Higher rates of rejection in HIV-infected kidney transplant recipients on ritonavir-boosted protease inhibitors: 3-year follow-up study.

Rejection rates in HIV-infected kidney transplant (KTx) recipients are higher than HIV-negative recipients. Immunosuppression and highly active antiretroviral therapy (HAART) protocols vary with potentially significant drug-drug interactions, likely influencing outcomes. This is an IRB-approved, single-center, retrospective study of adult HIV-infected KTx patients between 5/2009 and 12/2014 with 3-year follow-up, excluding antibody-depleting induction.

Transplant renal artery stenosis: clinical manifestations, diagnosis and therapy.

Transplant renal artery stenosis (TRAS) is a well-recognized vascular complication after kidney transplant. It occurs most frequently in the first 6 months after kidney transplant, and is one of the major causes of graft loss and premature death in transplant recipients. Renal hypoperfusion occurring in TRAS results in activation of the renin-angiotensin-aldosterone system; patients usually present with worsening or refractory hypertension, fluid retention and often allograft dysfunction.

Histopathology of renal failure after heart transplantation: a diverse spectrum.

Background: Chronic kidney disease occurs frequently after heart transplantation and is associated with significant morbidity and mortality. Herein we describe the histopathology associated with renal failure in a cohort of heart transplant recipients.

Methods: Over a 4-year period all patients with an estimated GFR <30 ml/min/1.

Antibodies reactive to non-HLA antigens in transplant glomerulopathy.

Although T and B cell alloimmunity contribute to transplant injury, autoimmunity directed at kidney-expressed, non-HLA antigens may also participate. Because the specificity, prevalence, and importance of antibodies to non-HLA antigens in late allograft injury are poorly characterized, we used a protein microarray to compare antibody repertoires in pre- and post-transplant sera from several cohorts of patients with and without transplant glomerulopathy. Transplantation routinely induced changes in antibody repertoires, but we did not identify any de novo non-HLA antibodies common to patients with transplant glomerulopathy.

Factors associated with failure to list HIV-positive kidney transplant candidates.

With improved survival in the antiretroviral era, data from ongoing studies suggest that HIV patients can be safely transplanted. The disproportionate burden of HIV-related end-stage renal disease in minority populations may impose additional obstacles to successful completion of the transplant evaluation. We retrospectively reviewed 309 potentially eligible HIV patients evaluated for kidney transplant at our institution since 2000.
