Renal Doppler Resistance Indices in Kidney Transplant Recipients With Proteinuria.

Background: The onset of proteinuria in renal transplant recipients may be associated with an increased risk of allograft failure. Little is known about the relationships between factors influencing proteinuria and the Doppler ultrasound (DU) intrarenal resistive index (RI) and pulsatility index (PI) among donor recipients with proteinuria <1000 mg/24 h.

Methods: We assessed correlations between the DU RI and PI and protein content in 93 selected renal transplant recipients: 62 patients with proteinuria 100 to 299 mg/24 h, 16 patients with proteinuria 300 to 499 mg/24 h, and 15 patients with proteinuria 500 to 999 mg/24 h.

Doppler ultrasound findings in kidney transplant recipients with and without of new onset diabetes mellitus beyond 5 years after transplantation.

Objective: Renal Doppler Ultrasound (RDU) indices: resistive index (RI) and pulsatility index (PI) are frequently applied as a noninvasive method that measured possible causes of allograft dysfunction in kidney transplant patients. We aimed to compare long-term prognosis and associated risk factors including the RDU markers in recipients with and without new-onset diabetes after transplantation (NODAT) beyond 5 years after kidney transplantation.

Methods: A prospectively maintained database of 137 kidney allograft recipients, transplanted in a single center, maintained on reduced tacrolimus-based immunosuppressive regimen and angiotensin receptor blocker (ARB) was retrospectively analyzed.

Late-Onset BK Viruria in Renal Transplant Recipients.

Background: Most cases of BK virus (BKV) infections emerge within the 1st years of kidney transplantation. We aimed to determine the prevalence of late-onset BKV infection and whether there are any differences between risk factors in early and late BKV infections.

Methods: In this single-center retrospective study, we reviewed 300 kidney transplant recipients that were under regular follow-up and selected recipients with BKV infection and recorded associated risk factors, connection with immunosuppression, and responses to modification of treatment.

HLA-identical sibling renal transplantation: influence of donor and recipient gender mismatch on long-term outcomes.

Background: Long-term function of living-related kidney allograft depends on multiple variables. The aim of the present study was to assess the influence of donor and recipient gender mismatch on the short and long-term outcomes in human leukocyte antigen (HLA)-identical sibling renal transplants (SRTs) receiving induction therapy and different immunosuppressive regimens.

Material And Methods: Twenty-nine recipients who were grafted from their HLA-identical siblings between 1994 and 2008 were divided into 2 groups (same and mismatched) according to gender of donor and recipient.

Determining renal resistive and pulsatility indexes long-term after kidney transplantation in kidney transplant recipients on cyclosporine a-, tacrolimus-, or sirolimus-based regimens.

Background: Renal Doppler ultrasound intrarenal resistive index (RI) and pulsatility index (PI) are 2 noninvasive Doppler ultrasonographic markers to determine kidney allograft function, and have been used mainly for diagnosing allograft dysfunction during early posttransplantation periods. Little is known about the stability of RI and PI in allograft recipients receiving cyclosporine A (CyA)-, tacrolimus (TAC)-, or sirolimus (SRL)-based immunosuppressive regimens long-term after kidney transplantation.

Methods: This study assessed RI and PI by Doppler ultrasonography in 155 kidney allograft recipients between July 2012 and March 2013.
