Article Synopsis
  • The study aimed to assess the effectiveness of multiple-target therapy for treating posttransplant focal segmental glomerulosclerosis, as there is no agreed-upon treatment strategy.
  • Thirteen patients underwent the therapy, with only 15.4% achieving complete or partial remission, while 38% faced graft loss within a year.
  • High rates of treatment discontinuation (77%) were noted, primarily due to infections, with cytomegalovirus being the most common complication, indicating that the therapy's effectiveness was limited.

The optimal immunosuppressive regimen for recipients of expanded criteria donor (ECD) kidneys has not been identified. In this single-center study, 171 recipients of ECD kidney transplants were randomized to receive antithymocyte globulin induction, and delayed introduction of reduced dose tacrolimus, prednisone and everolimus (r-ATG/EVR, n = 88), or mycophenolate (r-ATG/MPS, n = 83). No cytomegalovirus (CMV) pharmacological prophylaxis was used.

Introduction: The complex interaction between cytomegalovirus (CMV) infection and acute rejection after kidney transplantation is well recognized.

Methods: This single center retrospective cohort analysis investigated the incidence and risk factors associated with CMV infection after treatment for acute rejection (tAR) in kidney transplant recipients receiving only CMV preemptive therapy. Of the 938 kidney transplants performed between 04/30/2014 and 04/30/2015 we identified 87 (9.

Unlabelled: Cytomegalovirus (CMV) infection in kidney transplantation has changed its clinical spectrum, mostly due to the current and more effective immunosuppression. In the absence of preventive strategies it is associated with significant morbi-mortality.

Objective: This study evaluated the incidence of CMV events and its effect on outcomes of kidney transplantation in recipients without pharmacological prophylaxis or targeted preemptive treatment.

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.

Aim: This study was designed to identify optimal therapeutic sirolimus (SRL) concentrations in black kidney transplant recipients on reduced cyclosporine (CsA) exposure and prednisone.

Methods: Seventy patients (64 living/six deceased) received CsA (8-10 mg/kg/d), prednisone, and 15 mg loading dose followed by 5-mg fixed doses of SRL till day 7 when they were randomized to maintain SRL trough concentrations (high-performance liquid chromatography) of 8-12 (GI = 34) or 15-20 (GII = 36) ng/mL.

Results: Mean CsA concentrations were 109 +/- 53 vs.
