Outcomes of HIV-infected Patients on Dialysis: Experience at a Tertiary Care Center

Background: Human immunodeficiency virus (HIV) infection is a major public health problem. These patients are at an increased risk for end-stage kidney disease. Both hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) are the accepted modalities of treatment. Materials and methods: In this retrospective study, we included all HIV-positive end-stage kidney disease (ESKD) patients who were on dialysis - HD or CAPD - for at least 1 month. Data were collected from the dialysis charts and analyzed. Results: There were 20 patients in the CAPD group and 76 patients in the HD group. Mean age was 49.6 +/- 8.73 years in the CAPD group and 46.28 +/- 9.02 years in the HD group. Hypertension and diabetes were the common causes for ESKD. Mean survival was slightly better in CAPD group (20.94 vs. 15.46 months). The HD group had higher mortality within 12 months of dialysis initiation, and infection was the cause for early deaths. Mean infection episodes was 2.1 in HD group and 3.1 in CAPD group. CAPD patients with low albumin (<2.5 g/dl) had higher peritonitis rates. Conclusion: Managing HIV-positive dialysis patients remains challenging. In our study, survival was marginally better in the CAPD group. In both groups, low CD4 count was associated with more infections and low albumin with more peritonitis episodes. A study incorporating more peritoneal dialysis (PD) patients, longer follow-ups, and a matched non-HIV control will throw more light on patient outcomes.
