BK polyoma virus (BKV) belongs to Polyomaviridae family. It is a double-stranded DNA virus. Only a few cases of BKV--associated neurological disease in renal transplant recipients have been reported. BKV related central nervous system (CNS) infection may often remain unrecognized in immunocompromised patients. Here, we are reporting a case of BKV encephalitis post renal transplantation for the awareness of all physicians regarding this entity. [ABSTRACT FROM AUTHOR]

Aims and Objectives: The aim was to assess the prevalence and treatment of BK virus nephropathy (BKVN) in patients who underwent renal transplantation at a single center in South India with a 1-year follow-up analysis. To assess the efficacy of treatment with intravenous immunoglobulin (IvIg) in cases of proven BKVN. Materials and Methods: Three hundred and seventy-one patients underwent renal transplantation from 2018 to 2020. All were screened for BKVN with quantitative serum polymerase chain reaction (PCR) every 3 months for 1 year after transplant. Patients with positive tests underwent renal allograft biopsy. In all patients, antimetabolite was stopped, tacrolimus dose was reduced, and leflunomide was started. All patients with biopsy-proven BKVN were administered IvIg 2 grams/kg over 5 days and had a 1-year follow-up. Results: Fourteen patients had BK viremia; 12 had biopsy-proven BKVN. All were male with a mean age of mean age: 45.3 years ± 14.8 standard deviation (SD). Induction: basiliximab (7) and antithymocyte globulin (ATG) (7). Maintenance immunosuppression: tacrolimus, enteric-coated mycophenolate mofetil, and prednisolone. The median presentation time was 12 months. Mean graft function: baseline S. Creatinine of 1.32 mg/dL changed to 2.01 mg/dL at diagnosis. The mean presenting BKV PCR (copies/ml) was 44912 ± 56285 SD. No significant differences were observed in time of presentation, severity, mean tacrolimus level, and graft failure between patients receiving basiliximab or ATG. There were two relapses; two grafts failed. Class I BKVN had a better prognosis. Graft survival at 1 year was 85.71%. Conclusions: This is the first South Asian follow-up study of BKVN in kidney transplant recipients treated with IvIg. BKVN was documented in the first 15 months after transplant. There was no increased prevalence of BKVN in patients with ATG. Histopathological class has prognostic relevance with Class I having a better prognosis. Multipronged treatment, including IvIg, leads to 1-year graft survival of 85.71%. Long-term outcomes need follow-up. [ABSTRACT FROM AUTHOR]

Objectives: We aimed at creating a clinical profile of end-stage renal disease patients' gonadal function and assessing the impact of renal transplant on gonadal dysfunction. We studied the influence of age, vascular anastomosis, dialysis vintage, and immunosuppression on sexual dysfunction. Materials and Methods: Twenty adults were included. Hormones (luteinizing hormone [LH], follicle-stimulating hormone [FSH], testosterone, prolactin (PRL), and estrogen), menstrual history and International Index of Erectile Function (IIEF)-5 questionnaires were assessed before and after renal transplantation. Hormone evaluation was done by chemiluminescent microparticle immunoassay technology. Results: Seventeen patients were male and three patients were female. Native kidney diseases were chronic glomerulonephritis (10%), IgA nephropathy (20%), autosomal dominant polycyctic kidney disease (5%), diabetic nephropathy (5%), focal segmental glomerulosclerosis (5%), renal calculus disease (5%), membranous nephropathy (5%), and pauci-immune vasculitis (5%). Fifteen males had erectile dysfunction (ED) before transplant. Eleven patients showed an increase and six patients showed a decrease in IIEF scores posttransplantation. Statistically significant changes were observed in the mean levels of testosterone, LH, PRL, and FSH. Age at transplant showed a negative correlation with IIEF score. In five patients with an end to side anastomosis to the external iliac artery, all had an increase in IIEF score posttransplant. In 12 patients with an end to end anastomosis to the internal iliac artery, 5 patients (42%) had a decrease in IIEF score posttransplant. Conclusions: Incidence of ED was 88% in our study. About 65% patients showed an increase in IIEF score posttransplantation. Increasing age at the time of transplant was a significant risk factor for the presence of ED. Renal transplantation corrected hormonal abnormalities in men. About 100% of patients with an end to side arterial anastomosis showed improvement in IIEF scores. There was no effect of dialysis vintage and immunosuppression regimes on sexual dysfunction. [ABSTRACT FROM AUTHOR]

Introduction: Renal transplantation offers the best chance of survival to children with End Stage Renal Disease (ESRD). Patient survival and growth are superior in children with a renal allograft compared to dialysis. The aim of the study was to evaluate the outcomes of pediatric transplants done at a tertiary care hospital in Kochi, India over the study period. Materials and Methods: In this retrospective study, the data of children who underwent renal transplantation at Amrita Institute of Medical Sciences from 2002 to 2016 Kochi were analyzed. Results: Thirty-four children underwent renal transplantation over a 14-year period. Thirty-three underwent live related transplant whereas one underwent deceased donor transplantation. The mean age and weight of the recipients at transplantation was 14.3 years and 35.7 kg, respectively. Fourteen children were boys and twenty were girls. Thirty-one patients underwent hemodialysis prior to transplant, 2 were taken up preemptively, and 1 patient was on continuous ambulatory peritoneal dialysis. There were 5 documented urinary tract infections. No surgical complications were noted in the immediate post-transplant period. There were 5 episodes of acute rejection (14.7%). Two cases experienced Delayed Graft Function and the patient survival rate was 100%. Conclusions: Renal transplantation is a viable option to manage children with ESRD with satisfactory long term results and can be done in a developing nation's set-up. [ABSTRACT FROM AUTHOR]
