BACKGROUND: Cytomegalovirus (CMV) infection is one of the most important infectious diseases affecting recipients of kidney transplantation (KTx). However, the timing of seroconversion for CMV infection in seronegative recipients remains unclear. We evaluated CMV infections in CMV-seronegative recipients and the time to acquire antibodies against CMV. METHODS: We conducted a retrospective study of 228 recipients who underwent KTx between March 1988 and February 2018 at the Niigata University Hospital. The anti-CMV IgG antibody profile before and after transplantation was analyzed. Oral acyclovir or valganciclovir was used as prophylactic therapy for at least 6 months after transplantation. Cytomegalovirus infection was defined as CMV viremia detected using the CMV pp65 antigenemia assay. RESULTS: In this study, 50 cases (21.9%) were CMV-seronegative recipients. Over a median follow-up period of 126.7 months, 68% (34/50) of CMV-seronegative recipients experienced CMV viremia or overt disease symptoms as the first episode of CMV infection. The median duration from transplant to CMV infection was 69.0 days (range, 22-7426). All the recipients who experienced CMV infections acquired seroconversion. The median duration from KTx to seroconversion was 7.2 months (range, 2.8-252.3). Almost all CMV-seronegative recipients could acquire anti-CMV IgG antibodies within 2.5 years. In seronegative recipients whose donors were seronegative, no CMV viremia was found, and none developed anti-CMV IgG antibodies. CONCLUSIONS: In the clinical practice of CMV-seronegative recipients, we should consider that physicians must closely monitor the occurrence of CMV infection up until 2.5 years after KTx.

INTRODUCTION: Cytomegalovirus (CMV) is well established to be an independent risk factor for graft loss after kidney transplantation (KTx). Monitoring for CMV in the chronic phase is not defined in the current guideline. The effects of CMV infection, including asymptomatic CMV viremia, in the chronic phase are unclear. METHODS: We performed a single-center retrospective study to investigate incidence of CMV infection in the chronic phase, defined as more than 1 year after KTx. We included 205 patients who received KTx between April 2004 and December 2017. The CMV pp65 antigenemia assays to detect CMV viremia were continuously performed every 1-3 months. RESULTS: The median duration of the follow-up was 80.6 (13.1-172.1) months. Asymptomatic CMV infection and CMV disease were observed in 30.7% and 2.9% in the chronic phase, respectively. We found that 10-20% of patients had CMV infections in each year after KTx which did not change over 10 years. The history of CMV infection in the early phase (within 1 year after KTx) and chronic rejection were significantly associated with CMV viremia in the chronic phase. CMV viremia in the chronic phase was significantly associated with graft loss. DISCUSSION: This is the first study to examine the incidence of CMV viremia for 10 years post KTx. Preventing latent CMV infection may decrease chronic rejection and graft loss after KTx.

(Objective) Pregnancy in kidney transplant recipient continues to remain challenging due to a high rate of cesarean section along with preterm delivery, and concern for worsening renal function. This study examined the prognosis and perinatal management of post-transplant pregnancies. (Patients and methods) A total of nine post-transplant recipients at Niigata University Medical and Dental Hospital between 2007 and 2021 were retrospectively examined. (Results) All pregnancies were planned. Calcineurin inhibitors and steroids were continued, and antimetabolites were changed to azathioprine. The mean age at delivery was 33±3.8 years, and the mean time from renal transplantation to delivery was 6.5±3.5 years. Five patients (55.5%) had cesarean sections, while four (44.5%) patients had normal vaginal deliveries. The mean gestational age was 35±3.0 weeks, and the mean birth weight was 2,336±565.4 g. No congenital malformation was observed. The most common reason for early delivery was worsening renal function, seen in six (66.7%) patients. The mean serum creatinine level before pregnancy was 1.11±0.23 mg/dL and then worsened to 1.59±0.37 mg/dL during pregnancy. However, it recovered to 1.14±0.40 mg/dL after delivery. One patient had antibody-mediated rejection with donor specific antibody (DSA) prior to pregnancy, and her renal graft function worsened slightly after delivery. Another patient had a de novo DSA after delivery, which was not detected before pregnancy. (Conclusions) In our hospital, pregnancy in kidney transplant recipients were safe and renal graft function after delivery was relatively stable. Patients may require adjustment of calcineurin inhibitors during pregnancy, and the appearance of DSA after delivery should be noted.

BACKGROUND: The aim of this study was to determine the appropriate body mass index (BMI) in Japanese kidney transplant (KTx) recipients. We analyzed the effects of pre- and post-transplant (Tx) obesity on graft and patient survival, perioperative complications, post-transplant diabetes mellitus (PTDM), and cardiovascular disease (CVD) in Japanese KTx recipients. METHODS: This retrospective study included 269 recipients who underwent KTx from 2008 through 2020 at Niigata University Hospital. Obesity was defined as a body mass index (BMI) ≥25 kg/m2. We examined the association between pre- and post-Tx obesity and graft survival, patient survival, the incidence of PTDM and CVD, and perioperative surgical complications. RESULTS: The graft survival rate was lower in the pre-Tx BMI ≥25 kg/m2 group, although there was no significant difference in patient survival. There was no difference in graft and patient survival between the post-Tx BMI ≥25 kg/m2 group and the <25 kg/m2 group. A pre-Tx BMI ≥25 kg/m2 was an independent risk factor for biopsy-proven allograft rejection. New-onset DM after transplantation was significantly more common in the BMI ≥25 kg/m2 group than in the BMI <25 kg/m2 group (36% vs 13%; P = .002). The incidence of CVD was significantly higher in the post-Tx BMI ≥30 kg/m2 group than in the BMI <30 kg/m2 group (50% vs 11%; P = .023). There were no differences in surgical operating time, intraoperative blood loss, or perioperative complications between the obese and non-obese groups. CONCLUSION: Pre-Tx BMI ≥25 kg/m2 may be a risk factor for allograft rejection and graft loss. Post-Tx BMI should be <25 kg/m2 to reduce the risk for PTDM.

BACKGROUND: ABO antigens expressed on the red blood cells (RBCs) are not identical to those expressed on the renal endothelial cells. The isohemagglutinin assay employing the RBCs is the gold standard for evaluating anti-ABO antibody (Ab) levels. However, it remains unclear whether the anti-ABO Abs detected by the isohemagglutinin assay after ABO-incompatible (ABOi) kidney transplantations (KTx) that are not associated with antibody-mediated rejection can bind to renal graft endothelial cells. METHODS: Ninety plasma samples were collected from patients with stable graft function after ABO-compatible (ABOc) or ABOi KTx. Anti-ABO Ab titers were examined by both the isohemagglutinin assay and the CD31-ABO microarray, which was developed as a mimic of the ABO antigens expressed on the renal endothelial cells. RESULTS: The antibody titers detected by the isohemagglutinin assay and the CD31-ABO microarray after the ABOc KTx relatively correlated with each other. However, the CD31-ABO microarray results showed low antibody levels against donor blood group antigens after ABOi KTx and did not correlate with the isohemagglutinin assay. In contrast, the antibody levels against non-donor blood group antigens after ABOi KTx were comparable to those after the ABOc KTx. Fourteen patients received graft biopsies, and no antibody-mediated rejection was observed in ABOi KTx recipients, except for two patients who had anti-donor-HLA Abs. CONCLUSION: The present study suggested that the anti-ABO Abs detected by the isohemagglutinin assay after ABOi KTx with stable graft function were hyporeactive to the ABO antigen of graft renal endothelial cells.

Isohemagglutinin assays employing red blood cells (RBCs) are the most common assays used to measure antibody titer in ABO-incompatible kidney transplantation (ABOi KTx). However, ABO antigens expressed on RBCs are not identical to those of kidney and antibody titers do not always correlate with clinical outcome. We previously reported that CD31 was the main protein linked to ABO antigens on kidney endothelial cells (KECs), which was different from those on RBCs. We developed a new method to measure antibody titer using a microarray of recombinant CD31 (rCD31) linked to ABO antigens (CD31-ABO microarray). Mass spectrometry analysis suggested that rCD31 and native CD31 purified from human kidney had similar ABO glycan. To confirm clinical use of CD31-ABO microarray, a total of 252 plasma samples including volunteers, hemodialysis patients, and transplant recipients were examined. In transplant recipients, any initial IgG or IgM antibody intensity &amp;gt;30,000 against the donor blood type in the CD31-ABO microarray showed higher sensitivity, specificity, positive predictive value, and negative predictive value of AABMR, compared to isohemagglutinin assays. Use of a CD31-ABO microarray to determine antibody titer specifically against ABO antigens expressed on KECs will contribute to precisely predicting AABMR or preventing over immunosuppression following ABOi KTx.

BACKGROUND: Although monofilament mesh-based repair is a safe and effective procedure for incisional hernia (IH) in organ transplant patients, there is no definite evidence of IH treatment for patients with graft rejection and enhanced immunosuppressive therapy. We report a successful case of large IH repair using an autologous thigh muscle fascia sheet in a kidney transplant patient. CASE PRESENTATION: A 69-year-old man had IH from the incision of kidney transplantation, which was performed 6 years ago. He had a large right lower abdominal distension hanging down to the inguinal portion. A computed tomography scan revealed a large IH with a maximum abdominal defect diameter of 15 cm. The hernia sac contained the intestine, colon, and transplanted kidney, which had pulled out along with the retroperitoneum and protruded into the abdominal wall. He had chronic active acute antibody-mediated rejection, which required frequent steroid pulse therapy and additional or adjusted immunosuppressive drugs. After total circumferential exposure of the hernia sac and abdominal fascia, the abdominal wall defect was closed using a horizontal mattress suture. The sutured line was covered with a thigh muscle fascia sheet harvested from the patient's right femur and attached to the closed fascia. He was discharged on postoperative day 13 without any complications, and no IH recurrence was observed 10 months after surgery. CONCLUSIONS: Hernia repair using autologous tissue could be a treatment option for post-transplant IH with a higher risk of infection.

BACKGROUND: As the number of long-term survivors after organ transplantation increases, malignancy has become a problem as a late complication. We herein report a case of endometrial cancer during the follow-up of pancreas transplantation after kidney transplantation. CASE PRESENTATION: A 49-year-old woman was diagnosed with endometrial cancer. The patient had developed type 1 diabetes at 8 years old and started insulin treatment, and at 29 years old, she started hemodialysis for diabetic nephropathy. At 31 years old, she received living donor kidney transplantation and withdrew from dialysis. Hypoglycemia unawareness began to occur frequently from around 36 years old, and at 48 years old, the patient underwent deceased donor pancreas transplantation after kidney transplantation and achieved insulin independence. At 49 years old, she was diagnosed with endometrial cancer. Surgical treatment (total abdominal hysterectomy with left salpingo-oophorectomy) was performed. The pathologic diagnosis was confirmed as stage 1A uterine endometrioid carcinoma grade 1. The postoperative course was uneventful. She was discharged from our hospital on postoperative day 8. There has been no evidence of recurrence and/or metastasis of endometrial cancer for 16 months since the surgery. CONCLUSIONS: Carcinogenesis after pancreas transplantation may be a lethal late complication. It is important to carry out regular screening examinations with carcinogenesis in mind.

We herein report the case of a 20 year-old-man who developed bronchiolitis obliterans after living-donor renal transplantation. The patient presented with dyspnea on exertion and wheezing two years after renal transplantation, and spirometry showed an obstructive pattern. Surgical lung biopsy revealed subepithelial fibrosis that constricted and obstructed the intrabronchiolar space. Based on these findings, the patient was diagnosed with bronchiolitis obliterans. He was prescribed bronchodilators and azithromycin, and he achieved stable respiratory function for two years. The differential diagnosis of respiratory symptoms after renal transplantation includes opportunistic infection and drug-induced lung injury; however, bronchiolitis obliterans should also be considered.

BACKGROUND: Cytomegalovirus (CMV) infection is one of the major factors that affect morbidity and mortality in kidney transplant (KTx) patients. The rate of CMV seropositivity in children before KTx is lower than that in adults; therefore, pediatric KTx patients have a higher risk of CMV infection. In Japanese pediatric KTx patients, preemptive therapy for CMV infection is a main conventional therapy. This study investigated whether this preemptive treatment would affect kidney function at 2 years post-KTx. METHODS: A total of 163 patients, that is approximately half of the Japanese pediatric KTx patients nationwide, were recruited to participate in our study. We compared the values of the sequential estimated glomerular filtration rate (eGFR) at two years post-KTx and other influencing factors in CMV viremia, CMV disease, and no-infection groups. RESULTS: Cytomegalovirus infection after KTx occurred in 75 patients (46.0%), 38.7% of whom developed CMV disease. The sequential eGFR values post-KTx did not differ significantly between the three groups. CMV infection was not significantly correlated with other factors, other infections (including Epstein-Barr [EB] virus infection), acute rejection (AR), or adverse events. Only prolonged duration of total hospitalization was significantly associated with CMV infection (P = .002). In the multivariate analysis, younger age, CMV infection, and adverse effects were independently significantly related to prolonged total hospitalization. CONCLUSION: Preemptive therapy for CMV infection evidenced by viremia and disease did not significantly influence kidney function in Japanese pediatric KTx patients at two years after the operation.

(Background) It has become evident in recent year that aldosterone has a pathogenic role in hypertension, heart failure and renal disease. Elevation of aldosterone occurs in a certain fraction of hemodialysis patients, and the adverse effects of hyperaldosteronism could pose a problem after kidney transplantation. Long-term effects of aldosterone level in renal transplant recipients remain unknown. (Materials and methods) All recipients underwent transplantation between 1996 and 2018 in Niigata university hospital were included in the study. Plasma renin activity (PRA) and plasma aldosterone concentration (PAC) were retrospectively analyzed in 210 recipients before and after kidney transplantation. (Results) Sixty percent of recipients had higher PRA than normal upper limit before and after transplantation. The use of angiotensin receptor blocker (ARB) or angiotensin-converting-enzyme inhibitor (ACEI) was significantly more frequent in the patients with hyperreninemia than those without one after transplantation. Sixty percent of recipients had higher PAC than normal upper limit before transplantation and it spontaneously decreased to normal level after transplantation in most of them. There was no significant correlation between PAC and blood pressure, recipient age, and renal graft function after transplantation. We divided the patients into two groups, with and without post-transplant hyperaldosteronemia. The patients with post-transplant hyperaldosteronemia (n=29) had higher diastolic blood pressure and less use of renin-angiotensin-aldosterone system (RAAS) inhibitors than those with normal PAC level. (Conclusions) The use of RAAS inhibitors should be considered in post-transplant hyperaldosteronemia patients to control blood pressure and to save their long-term renal graft and heart function.

A 68-year-old male patient received a living donor kidney transplantation 8 years earlier for end-stage kidney disease secondary to IgA nephropathy. His post-transplantation follow-up had been routinely performed with laboratory examinations, ultrasound, and computed tomography (CT). His kidney graft function had been excellent and stable, as shown by a baseline serum creatinine level of 1.0 mg/dL. At referral, regular follow-up ultrasound and CT showed allograft hydroureteronephrosis. He did not have any complaints, but his physical examination revealed right inguinal bulging that was 3.5 × 3.5 cm. Abdominal enhanced CT revealed transplant allograft hydroureteronephrosis due to ipsilateral herniation of ureteroneocystostomy into the right inguinal canal. His serum creatinine level was slightly elevated (1.1 mg/dL). Then, he underwent an open right inguinal hernia repair. Paraperitoneal allograft hydroureteronephrosis and bladder herniation was confirmed at surgery, and hernioplasty with polypropylene mesh reinforcement was successfully performed. The postoperative course was uneventful. He was discharged on the seventh day after surgery. Six weeks after surgery, CT revealed disappearance of allograft hydroureteronephrosis and no sign of inguinal hernia recurrence with the serum creatinine stable at 1.0 mg/dL. Transplant ureteral obstruction due to inguinal hernia is a rare complication after kidney transplantation. However, transplant ureter or bladder herniation should be considered in the differential diagnosis of graft hydroureteronephrosis for preventing allograft loss.

OBJECTIVES: To analyze the prevalence of systemic de novo thrombotic microangiopathy in ABO-incompatible kidney transplantation and risk factors associated with this condition. METHODS: A total of 201 patients who received living-donor kidney transplantation (114 patients with ABO-identical kidney transplantation and 87 patients with ABO-incompatible kidney transplantation) were retrospectively analyzed. Systemic de novo thrombotic microangiopathy was diagnosed clinically according to the presence of thrombocytopenia with microangiopathic hemolytic anemia and pathological findings of thrombotic microangiopathy. Anti-A and anti-B antibodies were purified from human plasma, and these antibodies' bindings to human kidney were investigated in vitro. RESULTS: ABO-incompatible kidney transplantation was a significant risk factor of systemic de novo thrombotic microangiopathy (odds ratio 55.9, 95% CI 1.8-8.9, P < 0.001) after transplantation. Multivariate logistic regression analysis showed that non-use of mycophenolate mofetil, pretreatment immunoglobulin G antibody titer ≥64-fold and pretransplant immunoglobulin M antibody titer ≥16-fold were significant risk factors for systemic de novo thrombotic microangiopathy in ABO-incompatible kidney transplantation. Microvascular inflammation of 1-h post-transplant biopsy could be observed more frequently in thrombotic microangiopathy patients than in non-thrombotic microangiopathy patients. Anti-A and anti-B antibodies purified from human plasma showed a strong in vitro reaction against human kidney when the antibody titer was ≥16-fold. CONCLUSIONS: Antibody titer should be decreased to ≤16-fold until the day of ABO-incompatible kidney transplantation by desensitization therapy including mycophenolate mofetil. The 1-h biopsy results might help to diagnose systemic de novo thrombotic microangiopathy.

Hepatitis E virus (HEV) infection has been recognized as an acute condition. However, recent reports have shown that immunocompromised patients, such as those receiving solid-organ transplantation, can develop chronic hepatitis with HEV infection. We report two cases of chronic hepatitis E after kidney transplantation (KT) who were successfully treated with ribavirin monotherapy. Several years after KT, both patients had sustained elevations in the levels of liver enzymes for a period of more than 6 months. Both patients had HEV infection, genotype 3a. Histological studies showed infiltration of inflammatory cells without fibrosis. Treatment included ribavirin monotherapy at a dosage of 600 mg daily for 3 months. One month after therapy initiation, HEV-RNA turned to negative, and remained negative at 24 weeks after ribavirin therapy without severe complications. Although the treatment of chronic hepatitis E is not fully established, ribavirin therapy can be a safe and effective treatment for chronic hepatitis E.

BACKGROUND: Brachytherapy is one of the standard treatments for localized prostate cancer (CaP). However, the feasibility of brachytherapy for renal transplant recipients (RTRs) is still uncertain. MATERIALS AND METHODS: Between August 2007 and March 2018, all patients who had undergone low-dose-rate (LDR) brachytherapy or high-dose-rate (HDR) brachytherapy for clinically localized CaP at our institution were retrospectively identified (n = 394). Of these patients, 3 had a history of renal transplantation. We reviewed all available clinical data retrospectively. RESULTS: All of the RTRs received ABO-incompatible renal grafts from their spouses and had stable renal graft function before the diagnosis of CaP. The median age at diagnosis of CaP was 65 years (range, 60-67 years). The median time between transplantation and brachytherapy was 7 years (range, 4-10 years). In all of the patients, clinical stage was cT1cN0M0. Two patients received 125I LDR-brachytherapy (dose, 145 Gy) and 1 patient was treated by 192Ir HDR brachytherapy (dose, 19 Gy in 2 fractions) combined with external beam radiation therapy of 39 Gy in 13 fractions. The median follow-up period after brachytherapy was 44 months (range, 34-50 months). During the follow-up period, none of the patients developed disease progression including biochemical recurrence or clinically significant adverse events associated with radiation therapy. CONCLUSIONS: LDR brachytherapy and HDR brachytherapy are safe and technically feasible in RTRs with CaP, and oncological outcomes in RTRs do not appear to be inferior to those of patients who did not receive renal transplant.

PURPOSE: The purposes of the present study were to evaluate growth rate of nonfunctioning adrenal incidentalomas (AIs) and their development to hormonal hypersecretion on follow-up. MATERIALS AND METHODS: A retrospective study was conducted from the electronic medical records. A total of 314 patients were diagnosed with adrenal tumors between 2000 and 2016. After excluding patients who had overt adrenal endocrine disorders or whose adrenal tumors were clinically diagnosed as metastatic malignancies, we investigated 108 patients with nonfunctioning AIs including characteristics, the treatment, the way of follow-up and pathology. RESULTS: Fifteen patients received immediate adrenalectomy because of the initial tumor size or patient's preference. Pathological examination revealed malignancy in 2 patients. In the remaining 93 patients, radiological examinations were performed periodically. Tumor enlargement of ≥ 1.0cm was observed in 8.6% of the patients who were followed up as nonfunctioning AIs with a median follow-up period of 61.5 months (range: 4-192). Eleven patients underwent adrenalectomy. On the pathological examinations, all of the tumors, which showed a size increase, were diagnosed as benign tumors. Regarding the followed up patients without adrenalectomy, only 2.4% of the patients had tumor enlargement during the prolonged follow-up. Furthermore, none of the patients developed hormonal hypersecretion or clinical signs such as obesity, glucose intolerance or poorly controlled hypertension. CONCLUSIONS: Tumor enlargement of AIs did not correlate with malignancy. The value of repeat radiological and hormonal examinations may be limited in the long-term follow-up of patients whose AIs are not enlarged.

Biologic agents are a beneficial therapy for juvenile idiopathic arthritis (JIA). However, there is a lack of evidence with regard to management of these agents for JIA patients who undergo kidney transplantation (KTx). A 36-year-old woman with JIA who was treated with tocilizumab targeting interleukin-6 (IL-6) receptor underwent ABO-incompatible kidney transplantation (ABOi KTx). To prevent over-immunosuppression, tocilizumab was discontinued before ABOi KTx. Rituximab, tacrolimus, mycophenolate mofetil, everolimus, and methylprednisolone were used for immunosuppression. Clinical remission of joint pain was maintained for over 3 years despite complete discontinuation of tocilizumab. Both serum IL-6 and soluble IL-6 receptor levels were markedly decreased, suggesting that multitargeted immunosuppression for ABOi KTx induced long-term clinical remission of JIA through inhibition of the IL-6 pathway. However, levels of C-reactive protein (CRP) and matrix metalloproteinase-3 (MMP-3) gradually increased thereafter and abatacept was initiated to prevent joint deterioration. These levels decreased without any adverse events. The patient's renal graft function was well maintained.

(Backgrounds) The efficacy of bortezomib for chronic antibody mediated rejection (CAMR) after kidney transplantation is still obscure. (Materials and methods) CAMR were persisted in 5 recipients who were treated with plasma exchange, low dose of IVIG, steroid pulse therapy, and rituximab. 1.3 mg/m2 of bortezomib was administered on days 1, 4, 8, 11. Serum creatinine (sCr) levels, anti-HLA antibodies, and histology were analyzed. (Results) Stable sCr levels were obtained in 3 out of 5 recipients. No one lost renal graft function during follow-up periods. Anti-HLA class I antibodies were significantly decreased after bortezomib treatment, however anti-HLA class II antibodies were not changed. Histology showed no improvement at 6 months after bortezomib administration. Two recipients whose sCr levels increased during follow-up had already had interstitial fibrosis and tubular atrophy (IF/TA) in histology before bortezomib treatment. (Conclusions) The use of bortezomib after IF/TA could be detected in histology may not contribute to stabilize renal graft function in CAMR.

(Background) Long-term care is necessary for normal growth and development of pediatric recipients of kidney transplants. We report on our experience with pediatric kidney transplantation (KTx) during the past 19 years. (Methods) We retrospectively analyzed the data from 26 recipients who received KTx between 1996 and 2014 at Niigata University Hospital (one patient underwent two consecutive KTx during the designated period). All recipients were 16 years old or younger at the time of KTx. (Results) The graft survival rates at 1, 5, and 10 years after transplantation were 96%, 96%, and 88%, respectively. Three recipients lost the renal graft function due to graft thrombosis, antibody mediated rejection and steroid resistant rejection. Drug non-adherence was associated with rejection episodes, which led to the increasing of estimated glomerular filtration rate (eGFR) level. In addition, renal graft function was related to the growth after KTx. Eighteen recipients graduated from high school during follow-up periods and 17 recipients obtained employment. (Conclusion) Interventions promoting adherence should be implemented among pediatric recipients and parents to optimize graft survival and growth after KTx. Successful KTx contributed the high rate of social participation and employment after pediatric KTx.

The mechanism of long-term B cell immunity against donor blood group antigens in recipients who undergo ABO-incompatible (ABOi) living-donor kidney transplantation (LKTx) is unknown. To address this question, we evaluated serial anti-A and anti-B antibody titers in 50 adult recipients. Donor-specific antibody titers remained low (≤1:4) in 42 recipients (84%). However, antibodies against nondonor blood group antigens were continuously produced in recipients with blood type O. We stimulated recipients' peripheral blood mononuclear cells in vitro to investigate whether B cells produced antibodies against donor blood group antigens in the absence of graft adsorption in vivo. Antibodies in cell culture supernatant were measured using specific enzyme-linked immunosorbent assays (ELISAs). Thirty-five healthy volunteers and 57 recipients who underwent ABO-compatible LKTx served as controls. Antibody production in vitro against donor blood group antigens by cells from ABOi LKTx patients was lower than in the control groups. Immunoglobulin deposits were undetectable in biopsies of grafts of eight recipients with low antibody titers (≤1:4) after ABOi LKTx. One patient with blood type A1 who received a second ABOi LKTx from a type B donor did not produce B-specific antibodies. These findings suggest diminished donor-specific antibody production function in the setting of adult ABOi LKTx.

A 56-year-old woman had complained of two year's consecutive left-side abdominal pain. Retroperitoneal tumor was diagnosed and the patient was referred to our institute in December 2014. Laboratory data including endocrinological activity and serological markers were within the normal ranges. Imaging studies showed that the solid tumor measuring 5 cm in diameter was uncovered in the retroperitoneum, between the abdominal aorta and left kidney. The patient underwent surgical removal of the tumor with the left kidney because the mass was highly adhesive to the left ovarian vessels and left renal vein. Histological examination showed proliferating spindle cells in the tumor, and immunoreactivity for desmin and alfa-smooth muscle actin in tumor cells confirmed the diagnosis of leiomyosarcoma originated in left ovarian vein with left renal vein invasion. The patient has been free of disease 21 months after the surgery. Ovarian vein leiomyosarcoma is extremely rare and we have found 18 cases in literature. Furthermore, only three cases of leiomyosarcoma arising from the ovarian vein with the renal vein invasion were reported including our case.

<p>Hepatitis E identified as a zoonosis with a natural reservoir in pigs.<br/>Hepatitis E virus (HEV) infection attracted close attention in Japan after the fatal case of a patient with hepatitis E was reported in 2002, and after that reports of clinical HEV infection had increased rapidly. Infection via blood transfusion leads to further increased medical concerns. Subclinical infection is the most common situation, and rare cases of HEV infection develop acute hepatitis, which results in complete recovery. There were no data on chronic hepatitis E until recently. However, in organ-transplanted patients receiving immunosuppression therapy chronicity is a possibility, and these patients need close attention.<br/>Here we report four cases that developed hepatitis E after kidney transplantation and were diagnosed in our institution. We investigated the potential route of HEV infection and present a detailed clinical course in our cases.</p>

There have been few reports on allogeneic stem cell transplantation in patients who have previously undergone solid organ transplantation. The clinical course of such patients is not yet well recognized. Therefore, appropriate immunosuppressive prophylaxis for the rejection of a solid organ graft or for graft-versus-host disease has not yet been established. We present the case of a successful allogeneic stem cell transplantation in a patient who relapsed after a first allogeneic stem cell transplantation for myelodysplastic syndrome and who had previously undergone renal transplantation. The prophylaxis in this case for graft-versus-host disease and rejection of the transplanted kidney was mycophenolate mofetil and tacrolimus. No hyperacute rejection of the transplanted kidney was observed. However, the patient's renal function deteriorated after the cessation of the mycophenolate mofetil and the reduction of the tacrolimus. This deterioration seemed to be due to rejection with humoral immunity of donor lymphocytes, and we were able to control it by resuming the mycophenolate mofetil and local graft irradiation.

OBJECTIVE: The lymphocyte immunosuppressant sensitivity test has been used to predict the pharmacodynamics of immunosuppressive drugs for the purpose of preventing acute rejection and infection after renal transplantation. On the other hand, measuring the ATP levels in peripheral CD4+ lymphocytes is also able to monitor the risks of rejection and infection in transplant recipients. In the present study, we examined the relationship between the mycophenolic acid pharmacodynamics and the ATP levels in peripheral lymphocytes before and after renal transplantation. METHODS: We examined both the pharmacological efficacy of mycophenolic acid and the lymphocyte ATP levels before and 2, 4 and 6 weeks after the operation in 20 renal transplant recipients. The drug's pharmacological efficacy was evaluated by the 50% inhibitory concentration of the drug against the in vitro proliferation of peripheral blood lymphocytes activated by T cell mitogen. The ATP levels in peripheral CD4+ lymphocytes were measured by the Immuknow assay kit. The relationships between the mycophenolic acid pharmacodynamics and ATP levels in peripheral lymphocytes were examined in these recipients. RESULTS: The immunosuppressive effects of mycophenolic acid against mitogen-activated lymphocyte proliferation were significantly and positively correlated with the lymphocyte ATP levels, but only at 6 weeks after transplantation. The relationship was not significant before or at 2 or 4 weeks after the operation. CONCLUSION: Our present data raised the possibility that evaluating the pharmacological efficacy of mycophenolic acid pre-transplantation and monitoring the ATP level 6 weeks after transplantation can predict the risk of rejection and/or infection in renal transplant recipients.

A 36-year-old female received protocol biopsy at 1 month after living donor kidney transplantation. At 3 months post-transplantation, presence of a growing cystic mass in the kidney graft which had not been detected preoperatively, was demonstrated by ultrasound and computed tomography. The patient had an abdominal pain around the graft. Percutaneous drainage and sclerotherapy with minocyclin were performed twice, but the cystic mass, nevertheless, became enlarged and the abdominal pain recurred again. Laparoscopic fenestration was then performed. Immunohistochemistry of the cystic mass wall showed that it was CD34 (-), EMA (-), Megalin (-), but D2-40 (+). These results suggested that the cystic mass was derived from lymphatic vessels, which developed into lymphocele in the graft. We concluded that lymphatic vessels could have been injured and obstructed by the protocol biopsy. This is the first report of successful laparoscopic fenestration for lymphocele in the kidney graft.

OBJECTIVES: The adenosine triphosphate assay using peripheral lymphocytes may be useful to evaluate the risks of acute rejection and infection in kidney transplant patients. We used the adenosine triphosphate assay to evaluate differences between recipients who were treated with cyclosporine- or tacrolimus-based immunosuppressive therapy. MATERIALS AND METHODS: Adenosine triphosphate levels were measured in peripheral CD4+ cells before and after transplant and were correlated with clinical outcomes in 45 kidney transplant recipients. These recipients received immunosuppressive therapy with either cyclosporine (23 patients) or tacrolimus (22 patients). RESULTS: Adenosine triphosphate levels were significantly lower in the cyclosporine- than tacrolimus-based therapy groups from 2 to 6 weeks after transplant. Adenosine triphosphate levels were similar between these groups before and 1 week after transplant. The frequency of cytomegalovirus infection was greater in the recipients who received cyclosporine (17 patients [74%]) than tacrolimus (6 patients [27%]; P ≦ .003). The frequency of acute rejection episodes was similar between the cyclosporine and tacrolimus groups. CONCLUSIONS: These observations suggest that cyclosporine-based immunosuppressive therapy causes excessive immunosuppression compared with tacrolimus-based therapy, evidenced by the lymphocyte adenosine triphosphate levels. The adenosine triphosphate assay using peripheral CD4+ cells may be a useful method for predicting the occurrence of cytomegalovirus infections in kidney transplant recipients.

BACKGROUND: Patient and graft survival after successful kidney transplantation (KT) have improved despite an increase in the number of challenging cases. Various factors have evolved during the long history of kidney transplantation. METHODS: Between 1988 and 2012, a total of 292 living donor and 56 deceased donor KTs were performed at Niigata University Hospital. Long-term patient and graft survival and changes in background during a 20-year period in a single center were retrospectively analyzed. RESULTS: Excellent patient survival rates of 95.1% at 20 years for living donor KT and 96.2% at 15 years for deceased donor KT were observed. Graft survival rates at 1, 5, 10, 15, and 20 years were 96.8%, 95.4%, 83.1%, 61.8%, and 56.2% in living donor KT, respectively. In contrast, graft survival rates at 1, 5, 10, and 15 years in deceased donor KT were 89.0%, 80.3%, 77.3%, and 33.8%, respectively. These survival rates have dramatically improved since 2002 (91.7% for living and 80.9% for deceased donor KT at 10 years post-transplantation). The number of elderly recipients (older than 60 years) and the percentage of grafts donated from spouses have increased. The rejection rate decreased and the cytomegalovirus antigenemia-positive rate increased during the 20-year period assessed. The percentage of pre-emptive KTs progressively increased, with graft survival in this group tending to be better than non-preemptive KTs. The causes of graft loss were chronic allograft dysfunction (54.7%), acute rejection (11.1%), and malignancies (9.4%). After living donor KT, the principal predictors of graft loss were if the recipient was younger than 30 years, if the donor was older than 50 years, and if the rejection episodes occurred after living donor KT. In contrast, the only risk factor in the case of deceased donor KT occurred after transplantation from donors who were older than 50 years. CONCLUSIONS: A summary of the long-term outcome of KT over 20 years in a single center has been reported. Along with the changes in patient backgrounds, immunosuppressive drugs, and our knowledge of transplantation, patient and graft survival outcomes have also changed. Investigation into such outcomes during a different transplantation era is required to fully appreciate advances in KT.

ABO incompatible renal transplant recipients were administered immunosuppressive agents from one month before operation as desensitization immunosuppressive therapy. Lymphocyte-immunosuppressant sensitivity test(LIST)can predict the pharmacological efficacy for renal transplant recipients at just before transplantation. However, in case of ABO incompatible renal transplantation, the evaluation point of LIST has been unclear either at the beginning of desensitization immunosuppressive therapy or just before renal transplantation. Therefore, we evaluated pharmacological efficacies of tacrolimus(Tac), cyclosporine(CyA), and mycophenolic acid(MPA)by LIST, as well as ATP amounts in peripheral blood mononuclear cells(PBMCs)of patient origin, at both the beginning of desensitization immunosuppressive therapy and just before renal transplant operation. The study includes patients treated by Tac without basiliximab(Bax) (n=8), patients treated by Tac with Bax(n=10), and patients treated by CyA with Bax(n=11) immunosuppressive therapy. In the recipients treated by Tac without Bax, the rate of acute rejection episodes of the Tac high sensitivity group was significantly higher than that of the low Tac sensitivity group at only just before operation(p=0.022). However, the rate of cytomegarovirus (CMV)infection did not significantly correlate with Tac sensitivity. The rate of acute rejection episode or CMV infection was not significantly different between the above two patient subgroups at the beginning of desensitization immunosuppressive therapy. From these observations, we concluded that LIST should be carried out for the evaluation of Tac pharmacological efficacy at just before operation to predict occurrence of acute rejection episodes in renal transplantation.

BACKGROUND: Vascular endothelial cells (VECs) play crucial roles in physiological and pathologic conditions in tissues and organs. Most of these roles are related to VEC plasma membrane proteins. In the kidney, VECs are closely associated with structures and functions; however, plasma membrane proteins in kidney VECs remain to be fully elucidated. METHODS: Rat kidneys were perfused with cationic colloidal silica nanoparticles (CCSN) to label the VEC plasma membrane. The CCSN-labeled plasma membrane fraction was collected by gradient ultracentrifugation. The VEC plasma membrane or whole-kidney lysate proteins were separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis and digested with trypsin in gels for liquid chromatography-tandem mass spectrometry. Enrichment analysis was then performed. RESULTS: The VEC plasma membrane proteins were purified by the CCSN method with high yield (approximately 20 μg from 1 g of rat kidney). By Mascot search, 582 proteins were identified in the VEC plasma membrane fraction, and 1,205 proteins were identified in the kidney lysate. In addition to 16 VEC marker proteins such as integrin beta-1 and intercellular adhesion molecule-2 (ICAM-2), 8 novel proteins such as Deltex 3-like protein and phosphatidylinositol binding clathrin assembly protein (PICALM) were identified. As expected, many key functions of plasma membranes in general and of endothelial cells in particular (i.e., leukocyte adhesion) were significantly overrepresented in the proteome of CCSN-labeled kidney VEC fraction. CONCLUSIONS: The CCSN method is a reliable technique for isolation of VEC plasma membrane from the kidney, and proteomic analysis followed by bioinformatics revealed the characteristics of in vivo VECs in the kidney.

Pentraxin-3 (PTX3) is an acute phase reactant produced by a variety of cell types at sites of local inflammation. We examined by immunohistochemistry renal biopsies from patients with acute rejection (n = 10), protocol biopsies without rejection (n = 37), and peri-operative donor biopsies of the same transplant patients (n = 94) for intra-renal expression of PTX3, and its correlation with clinical, laboratory, and histopathologic parameters. PTX3 was mainly expressed in the interstitium of renal allograft. In the non-rejection biopsies (pre- and post-reperfusion and protocol biopsies), PTX3 expression area (PTX3%) was equally maintained at a low level, whereas in the rejection biopsies, PTX3% was significantly higher (p < 0.0001). Treatment of acute rejection resulted in a significant reduction of PTX3% (p < 0.0001). PTX3% positively correlated with the degree of allograft dysfunction and acute rejection scores of Banff classification (2009). This study suggests that PTX3% may be an available histological marker of acute renal allograft rejection.

The lymphocyte immunosuppressant sensitivity test (LIST) with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay procedure can predict the pharmacological efficacy of immunosuppressive agents. A previous study reported the pharmacological efficacy of tacrolimus evaluated by LIST just before renal transplantation significantly correlated with the incidence of acute rejection episodes. However, the pharmacological efficacy of tacrolimus has not been estimated after renal transplantation. Therefore, the present study evaluated the pharmacological efficacy of tacrolimus by LIST using the MTT assay procedure before and 1, 3, and 12 months after transplantation in 17 renal transplant recipients that received tacrolimus-based immunosuppressive therapy. The tacrolimus pharmacological efficacies before and after the procedure were also compared with incidence of acute rejection and cytomegalovirus (CMV) infection episodes. The individual values of tacrolimus 50% inhibition of lymphocyte proliferation (IC50) varied widely before transplantation, and the mean value of the IC50 was 126.4 ± 337.7 ng/ml. The patients were divided into two groups according to the tacrolimus IC50 values evaluated before transplantation. The rate of acute rejection episodes in the tacrolimus high-sensitivity group was significantly lower than that in the tacrolimus low-sensitivity group (p = 0.005). The tacrolimus IC50 deviation between patients expanded further at one and three months after surgery. However, the sensitivity deviation almost converged at 1 year after surgery. Moreover, the pharmacological efficacy of tacrolimus evaluated at 1, 3, and 12 months after transplantation did not significantly correlate with the incidence of acute rejection episodes. The pharmacological efficacies of tacrolimus evaluated at both before and after surgery were not significantly correlated with the episodes of CMV infection. These findings suggest that the pharmacological efficacy of tacrolimus evaluated with LIST before surgery is a useful biomarker for predicting the occurrence of acute allograft rejection in renal transplantation.

Basiliximab is a recently developed immunosuppressive agent for the prevention of acute allograft rejection in renal transplant recipients. The combination use of basiliximab and a calcineurin inhibitor was suggested to be more effective in comparison to immunosuppressive therapy using calcineurin inhibitor without basiliximab. Cyclosporine has been generally administered with basiliximab for renal transplant recipients. However, in cases of tacrolimus-based immunosuppressive regimen, the clinical efficacy and safety of combined use of tacrolimus and basiliximab remains to be elucidated. This study evaluated the tacrolimus pharmacological efficacy using a lymphocyte immunosuppressant sensitivity test (LIST) with MTT assay procedures in 16 cases of renal transplant recipients treated by tacrolimus without basiliximab and in 13 cases treated by tacrolimus in combination with basiliximab. The rate of acute rejection episodes in the recipients treated with tacrolimus plus basiliximab was 1/13 (7.7%), whereas the rate in the recipients treated with tacrolimus without basiliximab was 6/16 (37.5%). The recipients were divided into two groups according to their peripheral blood mononuclear cell (PBMC) sensitivity to tacrolimus [i.e., including a tacrolimus high sensitivity group (IC(50) <1.0 ng/ml) and a low sensitivity group (IC(50) >1.0 ng/ml). In the recipients treated with tacrolimus without basiliximab, the rate of acute rejection episodes in the tacrolimus high sensitivity group was 1/10 (10.0%), which was significantly lower than the rate in the low sensitivity group of 5/6 (83.3%; p = 0.008). The incidence of cytomegalovirus infection was not significantly different between the tacrolimus high and the low sensitivity groups of the recipients treated with tacrolimus with and without basiliximab. Therefore, in the case of selected tacrolimus-based immunosuppressive therapy for renal transplant recipients, the tacrolimus pharmacological efficacy should be evaluated using LIST at a time just before the transplant procedure in order to accurately predict allograft rejection. The data also suggested that low tacrolimus sensitivity recipients should be treated with tacrolimus-based immunosuppressive therapy in combination with basiliximab.

Use of generic drugs is recommended because of their economic advantage. However, bland and generic drugs have never been compared from the view point of their pharmacological efficacy by lymphocyte immunosuppressant-sensitivity test(LIST)with 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide(MTT)assay procedure. In this study, we evaluated the pharmacological efficacy of the bland and its generic drugs of methylprednisolone sodium succinate by LIST using peripheral blood mono nuclear cells (PBMCs) obtained from one healthy volunteer. The results showed wide difference of 90％ confidence interval between IC50 logarithmic value； however, there were no statistically significant difference in IC50 logarithmic values between these drugs. We concluded from these data that immunosuppressive pharmacological efficacy of these generic methylprednisolone sodium succinate was almost equivalent to that of the bland drug. However, further investigation is recommended to evaluate and confirm the pharmacological and economic advantage between bland and generic drugs by LIST.

BK virus (BKV) nephropathy is one of the major causes of allograft dysfunction or graft loss in kidney transplant recipients. Early diagnosis and timely reduction in immunosuppressant is important for proper treatment. We report a 35-yr-old male case of cadaveric renal transplantation with BK viral related tubulointerstitial nephritis complicated by acute rejection. The diagnostic biopsy showed severe inflammatory infiltrates, tubulitis, and peritubular capillaritis. Discontinuation of mycophenolate mofetil, prednisone pulse therapy, and r-globulin was successful in relieving allograft dysfunction.

OBJECTIVES: Cyclosporine and tacrolimus are calcineurin inhibitors that are used to prevent acute rejection in renal transplant recipients. The lymphocyte immunosuppressant sensitivity test (LIST) can predict the pharmacological efficacy of these immunosuppressive agents for renal transplant recipients. There is a correlation between cyclosporine and tacrolimus pharmacological efficacy as evaluated by LIST by the 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) assay procedure prior to renal transplantation. However, the LIST can also evaluate patients before and after the transplantation. MATERIALS AND METHODS: The present study examined the relationship between cyclosporine and tacrolimus pharmacological efficacy by LIST using the MTT assay in 16 renal transplant recipients at 1, 3 and 12 months after transplantation, as well as before the operation. RESULTS: The relationship of cyclosporine and tacrolimus pharmacological efficacy gave a significant Kendall and Spearman's coefficient correlation in these transplant recipients by the LIST using the MTT assay procedure immediately prior to renal transplantation (rk = 0.711, rs = 0.877, p < 0.01). Furthermore, correlations between the cyclosporine and tacrolimus IC50 values were also observed with a significant Kendall and Spearman's coefficient correlation at 1 and 12 months after transplantation (rk1month = 0.65, rs1month = 0.829, p < 0.01, and k12month = 0.433, rs12month = 0.603, p < 0.01, respectively). However, no statistically significant relationship was observed between the pharmacological efficacies of the calcineurin inhibitors at 3 months after transplantation (rk3month = 0.117, rs3month = 0.1, p > 0.05). CONCLUSIONS: Both cyclosporine and tacrolimus exhibit pharmacological efficacy by the inhibition of calcineurin. However, the correlation between cyclosporine and tacrolimus pharmacological efficacies may be altered, due to immunosuppressive therapy or clinical events at 3 months after renal transplantation.

The lymphocyte immunosuppressant sensitivity test (LIST) can predict the pharmacological efficacy of immunosuppressive agents. We herein estimated the mycophenolic acid efficacy using LIST before and 1, 3, and 12 months after the operation in 15 renal transplant recipients. The pharmacological efficacy of mycophenolic acid as assessed before transplantation showed small individual variations, whereas the variability greatly increased at 1 and 3 months after transplantation. Furthermore, the individual IC50 variation among these subjects at 1-year after operation was closely similar to that observed before surgery. No significant implications of these individual differences in the mycophenolic acid sensitivity were noted in regard to the clinical courses of these recipients.

At the age of three yr, a male patient had surgical treatment for bilateral vesicoureteral reflux (VUR), and at the age of 19 yr, he developed nephrotic syndrome because of focal segmental glomerulosclerosis (FSGS). His renal function deteriorated despite treatment with temocapril and aspirin, and dialysis treatment was started when he was 19. After nine yr of dialysis, he received a living kidney transplantation from his 58-yr-old father, who had a long history of hypertension. A graft biopsy before perfusion showed moderate arteriolosclerosis. As urine protein increased to 2.15 g/d at 16 months after kidney transplantation, the graft biopsy was performed again. FSGS lesion with severe arteriosclerosis was recognized under light microscope, while the effacement of podocyte foot processes was seldom observed. The alteration of calcineurin inhibitor from cyclosporine to tacrolimus, combined with the new administration of angiotensin receptor antagonist (valsartan) and aldosterone receptor blocker, successfully decreased the amount of urine protein to 0.8 g/d within two wk. We considered that the present case showed two distinct types of FSGS lesions--one because of VUR and the other because of cyclosporine arteriolopathy--in each native kidney and transplanted kidney.

Nonocclusive mesenteric ischemia (NOMI) is an infrequent and fatal disorder. We describe a 54-year-old man who developed NOMI during the peritransplant period following ABO-incompatible living-donor kidney transplantation, but who was successfully treated with his renal graft function unimpaired. Abdominal pain appeared on the sixth postoperative day (POD), and emergency surgery was performed on POD 8. Discontinuous segmental necrosis extended throughout the small intestine, and the necrotic segments were entirely removed. He thereafter had ischemia of the ascending colon, which was treated with colectomy, and prostaglandin E1 delivered through the related artery prevented advanced necrosis. Temporary colostomy was closed 20 months after surgery. He maintains excellent graft function at present without secondary disorder. There has been no ABO-incompatible kidney transplant recipient complicated with NOMI. However, patients with end-stage renal disease are at the highest risk for this lethal condition, and physicians and urologists should correctly recognize its diagnostics and therapeutics.

OBJECTIVE: Lymphocyte immunosuppressant sensitivity test (LIST) is useful for predicting the pharmacological efficacy of immunosuppressive agents. In this study, the pharmacological efficacy of cyclosporine was estimated by LIST before and after renal transplantation. METHODS: Lymphocyte immunosuppressant sensitivity test was performed by the 3-(4,5-dimethylthiazol-2-yl)-2,5diphenyltetrazolium bromide (MTT) assay before and at 1, 3, and 12 months after transplantation in 19 consecutive renal transplant recipients. RESULTS: There was wide intersubject variability in cyclosporine IC50 before transplantation [Mean (SD) of 593.9 (1067.6) ng/mL]. This variability worsened 1 month after transplantation [525.7 (1532.7) ng/mL] but decreased at 3 months (193.5 (347.9) ng/mL) and 12 months (75.4 (95.4) ng/mL). In this small study, observed differences in IC50 values for the individual subjects at various time intervals was not associated with the occurrence of rejection, graft loss, and infection episodes. CONCLUSION: Lymphocyte sensitivity to cyclosporine assessed by the LIST assay showed a high level of inter-subject variability particularly before and 1 month after transplantation. The observed difference in IC50 values was not associated with clinical outcome in this small study.

BACKGROUND: It is generally admitted that ABO(H) blood group antigens are linked to lipids and proteins. Although glycolipids carrying ABO antigens have been well characterized in human kidneys, glycoproteins carrying ABO antigens are largely unknown, and their molecular properties remain to be elucidated. METHODS: All the blood group A antigen-linked proteins in human kidney could be solubilized and captured on immobilized Helix pomatia lectin that recognizes A antigens. These proteins were separated on SDS-PAGE gels. The gel pieces containing protein bands immunoreactive with anti-A antibody were excised, in-gel digested with trypsin, and analyzed by nanoLC tandem mass spectrometer. Protein candidates that carry ABO antigens were confirmed by immunoprecipitation and double-labeled immunofluorescense microscopy. RESULTS: All the glycoproteins carrying ABO antigens were found to be Asn-linked glycoproteins, and presented as multiple bands on SDS-PAGE with molecular masses ranging from 60 to 270 kDa. The protein bands were subjected for mass spectrometric analysis, which identified 121 distinct proteins with high confidence. Of the identified proteins, 55 N-glycosylated, membrane proteins were selected as glycoprotein candidates that carry ABO antigens. Among them, most abundantly expressed proteins as estimated by the number of peptide matches in the MS spectrometric analysis, such as platelet endothelial cell adhesion molecule 1, plasmalemmal vesicle-associated protein, and von Willebrand factor, were further characterized. CONCLUSIONS: Several glycoproteins were identified that represented major glycoproteins carrying ABO antigens in the human kidney, which exhibited distinct features in localization to most of vascular endothelial cells.

The lymphocyte immunosuppressant-sensitivity test (LIST) has been reported extensively as being able to estimate the pharmacological efficacy of immunosuppressive drugs in individual patients. This study measured the IC50 values for 6 drugs, cyclosporine, tacrolimus, methylprednisolone, 6-mercaptopurine, mycophenolic acid, and mizoribine, against mitogen-induced proliferation of peripheral-blood lymphocytes in 29 renal transplant recipients. We also examined relationship between the IC50 values and 4 factors; age, duration of dialysis, percentage of lymphocytes in total white blood cells, and blastogenesis stimulation index by mitogen. There were no significant correlations between the IC50 values and these factors, except that the tacrolimus IC50 value was correlated weakly with the stimulation index (p<0.05, r=-0.429). It was concluded that the pharmacological efficacy of immunosuppressive drugs cannot be inferred from the patient characteristics or their laboratory data. LIST is an effective method to elucidate the pharmacodynamic properties of immunosuppressive agents in individual renal transplant recipients without being influenced by the recipient clinical data.

We present the case of a young lady who developed renal cell carcinomas (RCC) in the allograft and bilateral native kidneys metachronously within one year. She received a living donor kidney transplantation from her father. A solid tumor of 4 cm in diameter was uncovered first in the allograft kidney 103 months after transplantation, and was treated with graftectomy. Six months after graftectomy, a right renal tumor measuring 3.5 cm and left renal tumors emerged in the native kidneys. She underwent laparoscopic right and left radical nephrectomy in separate sessions. The pathological diagnosis in the allograft and right renal tumors was clear cell RCC with eosinophilic cytoplasm and that in the left kidney was clear cell carcinoma. Fluorescence in situ hybridization and human leukocyte antigen typing showed that each tumor was most probably primary disease. She was free of disease 18 months postoperatively. This is the first report on RCC arising both in the allograft and bilateral native kidneys.

Kidney transplantation has a powerful influence on the nutritional status of patients with end-stage renal disease. How to control diet varies in different races and periods after kidney transplantation. In general, malnutrition in patients with end-stage renal disease slowly recovers after kidney transplantation; however, several dietary interventions are required throughout the post transplant course. While hyperalimentation is warranted to control the hypercatabolic state immediately following the transplant operation, dietary restriction of protein, salt and calories is recommended to prevent life-style related diseases, which affect patient and graft survival. No consensus on dietary control in kidney transplant recipients has been reached yet. Herein, we present the nutritional status of Japanese kidney allograft recipients, discuss some unresolved nutritional problems and review the recent literature.

BACKGROUND: In Japan, ABO-incompatible (ABO-I) kidney transplantation began in 1989; these transplantations have flourished because of the lack of cadaveric donors, and more than 600 cases were performed up to 2004. Splenectomy has been considered to be necessary for successful ABO-I kidney transplantation, and the majority of pre-conditioning protocols include splenectomy in Japan. However, we have lost some grafts due to antibody-mediated rejection (AMR) accompanying explosive elevation of anti-A/B antibody (Ab) titer even though the patients had a low pre-operative Ab titer. PATIENTS AND METHODS: We utilized two doses of anti-CD20, rituximab, simply combined with mycophenolate mofetil (MMF)/low-dose steroid desensitization started 1 month before surgery in ABO-I kidney transplantation. Two sessions of pre-operative Ab removal by double filtration plasmapheresis or plasma exchange were carried out. We performed six ABO-I kidney transplantations without splenectomy. Anti-A/B Ab titers were more than 16 to 32 times before treatment. We did not plan any post-operative repeated Ab removal or intravenous immunoglobulin G (IVIG). RESULTS: Pre-operative anti-A/B Ab titers were successfully reduced to less than eight times in all cases. Except for one case in which we had to remove the graft due to aspiration pneumonia and methicillin-resistant staphylococcus epidermidis (MRSE) sepsis, the other five cases did not experience antibody-mediated rejection (AMR). An additional session of post-operative Ab removal and/or IVIG was not necessary. In all patients, B cells (CD19+, CD20+, CD21+) and activated T cells (CD25+) were selectively suppressed, although CD3+, CD4+ and CD8+ cell populations remained stable, thus we call our protocol "pinpoint targeted immunosuppression." Plasma immunoglobulin level was also successfully suppressed, especially after 6 weeks of surgery. CONCLUSION: Anti-CD20/MMF desensitization is safe and allows successful ABO-I kidney transplantation without splenectomy.

Vascular endothelial cells (ECs) are considered to be a primary target for injury in allograft rejection. However, the relationship between serum antibody activity to ECs and rejection episodes has not been examined extensively in renal transplantation. Twenty-two renal transplant recipients were included in this study. Serum antibody activity to vascular endothelial cells (AECA) was measured using a cellular enzyme-linked immunosorbent assay (ELISA) in which human umbilical vein endothelial cells (HUVEC) and human glomerular endothelial cells (HGEC) were preincubated with TNF-alpha used as target cells. Serum samples were obtained just before transplantation and once a week during the immediate 1-3-month post-transplantation period. There was a significant correlation between the presence of AECA against HGEC and rejection episodes (P < 0.05). Patients with multi-episodes of rejection showed significantly higher frequencies of AECA than patients with mono-episodic rejection (P < 0.0005). It should be noted that patients suffering from multi-episodes of rejection revealed higher AECA titres before transplantation. These findings imply that the HGEC-ELISA could be used as a prospective, informative test to identify patients with a higher risk of acute rejection in renal transplantation.
