RESUMO
Background and objectives: The HIV-associated renal diseases represent a spectrum. Indian data on this is sparse. This study was undertaken to find out the prevalence and clinicopathological spectrum of renal involvement in HIV among antiretroviral therapy (ART) naïve patients (Group 1) and among those on ART (Group 2). Methods: Systematic random sampling was undertaken to select 109 patients each from virology outpatient department (VOPD) and ART centre of a tertiary care hospital. They were screened and further investigated if renal involvement was found. Results: Renal involvement was present in 25/109 (22.94%) and 15/109 (13.76%) patients of Groups 1 and 2, respectively. Among patients of Groups 1 and 2, 9/24 (37.5%) and 2/13 (15.4%), respectively, had clinically significant proteinuria, but none in the nephrotic range. Statistically significant relationships of renal involvement were observed with CD4 count <100/µl and with low BMI. Of the patients of Group 2, 20% of those on a tenofovir-based regimen had renal involvement with tubular changes, while only 4.6% of those on other regimens had renal involvement. This difference was statistically significant (p<0.05; OR=5.25). Conclusion: Renal involvement was less common among those on ART. Low CD4 count and body mass index (BMI) were associated with renal dysfunction. Patients on a tenofovir-based regimen had more renal involvement compared with not on a tenofovir-based regimen.
