Renal Replacement Therapy in Patients With HIV Infection in a European Region: Outcomes Following Renal Transplantation

Introduction

The prognosis of HIV infection has improved dramatically in patients with end-stage renal disease (ESRD). Thus, HIV infection is no longer an absolute contraindication for renal transplantation.

Methods

A cross-sectional study was performed to analyze the characteristics of HIV patients receiving renal replacement therapy (RRT) in September 2011, using data from the Registry of Renal Patients in Andalusia. A retrospective cohort study was also carried out, analyzing patients receiving kidney transplants in the era of highly active antiretroviral therapy.

Results

In Andalusia in September 2011, 8744 patients were on RRT; of these, 48 had HIV infection (prevalence 0.54%). The RRT modality was very different between HIV-negative and HIV-positive patients: renal transplantation 49.2% and 16.7%, hemodialysis 46.8% and 81.3%, and peritoneal dialysis 4% and 2%, respectively. The most frequent ESRD etiology was glomerulonephritis (37.5%). Twenty-seven (56.3%) had hepatitis C coinfection. Only three patients (7.5%) were on the waiting list for renal transplantation. From 2001 to September 2011, 10 HIV-infected patients received a renal transplantation (median follow-up 40.5 months). The initial immunosuppressive treatment included tacrolimus and mycophenolate without induction therapy. Only two patients presented acute rejection, both borderline and corticosensitive. All remain alive and the graft survival was 100% in the first and third years posttransplant. We compared demographic and comorbidity variables between patients transplanted or included on the waiting list (n = 12) and patients excluded and never transplanted (n = 36). We found differences only in the ESRD etiology (higher incidence of glomerulonephritis in excluded patients).

Conclusions

Renal transplantation is safe in correctly selected HIV-infected patients. The number of patients on the waiting list is very small. This may reflect the high comorbidity but it is also possible that these patients are still not being assessed systematically for transplant in all centers.
