Recurrence of FSGS after Kidney Transplantation in Adults.

Background And Objectives: FSGS recurrence after kidney transplantation is a major risk factor for graft loss. However, the natural history, clinical predictors, and response to treatment remain unclear because of small sample sizes and poor generalizability of single-center studies, and disease misclassification in registry-based studies. We therefore aimed to determine the incidence, predictors, and treatment response of recurrent FSGS in a large cohort of kidney transplant recipients.

Clinical features and outcomes of kidney transplant recipients with focal segmental glomerulosclerosis recurrence.

Aim: Focal segmental glomerulosclerosis recurs in up to 30% and up to 80% of adult and pediatric kidney transplant recipients, respectively. There is no standard of care treatment. The purpose of this study was to evaluate clinical characteristics, treatments and outcomes of patients with focal segmental glomerulosclerosis recurrence (FSGSr).

A large, international study on post-transplant glomerular diseases: the TANGO project.

Background: Long-term outcomes in kidney transplantation (KT) have not significantly improved during the past twenty years. Despite being a leading cause of graft failure, glomerular disease (GD) recurrence remains poorly understood, due to heterogeneity in disease pathogenesis and clinical presentation, reliance on histopathology to confirm disease recurrence, and the low incidence of individual GD subtypes. Large, international cohorts of patients with GD are urgently needed to better understand the disease pathophysiology, predictors of recurrence, and response to therapy.

Clinical Presentation, Outcomes, and Treatment of Membranous Nephropathy after Transplantation.

There are scarce data about clinical presentation and outcomes of posttransplant membranous nephropathy (MN), and few reports include a large number of patients. This was a retrospective cohort including adult patients with posttransplant MN transplanted between 1983 and 2015 in a single center (n=41). Only patients with histological diagnosis of MN in kidney grafts were included.

Sepsis-like histoplasmosis in a kidney transplant patient.

Histoplasmosis is a fungus infection that mainly affects immunosuppressed patients. The authors present a case of a kidney transplant recipient who developed sepsis-like histoplasmosis, na atypical but severe manifestation of the disease. The fungus was found in blood and in a skin biopsy, and the treatment with liposomal amphotericin resulted in hepatotoxicity.

Genitourinary tuberculosis - a rare presentation of a still frequent infection in renal transplant recipients.

Mycobacterium tuberculosis infection in renal transplant recipients is associated with significant morbidity and mortality. Genitourinary tuberculosis is a less frequent presentation and a high level of suspicion is needed to avoid treatment delay. Management is challenging due to the interaction of calcineurin inhibitors with antituberculous medications and the known side effects of these drugs, with higher prevalence in this population.

Prospective Randomized Trial Investigating the Influence of Pharmaceutical Care on the Intra-Individual Variability of Tacrolimus Concentrations Early After Kidney Transplant.

Background: This study evaluated the influence of pharmaceutical care (PhC) in the intra-individual variability of dose-corrected whole blood tacrolimus (TAC) trough concentrations, adherence to immunosuppressive therapy and clinical outcomes.

Methods: We randomized 128 kidney transplant recipients to receive PhC consisted of predefined instructions provided by a pharmacist (PhC group, n = 64) or standard nurse staff instructions (control group, n = 64) from day 3 to day 90 after kidney transplantation. The study was powered to detect at least 50% reduction in the coefficient of variation (%CV), calculated from 6 dose-corrected whole blood TAC trough concentrations, in the PhC group.

Is there a role for urinary podocyte excretion assessment in lupus nephritis?

Objective: To establish the occurrence and intensity of podocyturia and its relation to grade of disease activity, as defined by clinical and laboratory criteria.

Methods: Prospective, cross-sectional study involving 50 patients with lupus nephritis and 29 controls, which had podocyturia levels determined from random urine samples using an immunofluorescence technique. Disease activity was graded by BILAG (renal criteria) and an additional system used in the service (S2).

Detection of podocyturia in patients with lupus nephritis.

Introduction: The podocyturia has been detected in glomerular diseases, such as lupus nephritis (LN), in which proteinuria is an important manifestation, and its occurrence seems to be limited to the active phase of the disease.

Objective: To evaluate podocyturia in LN patients, and the possible association with clinical disease activity.

Methods: We evaluated 56 patients with LN, that were classified in three groups according to the degree of clinical activity: Group B, no activity (n = 17), Group C with mild (n = 29) and Group D, moderate to severe activity (n = 10).
