Prevalence and Pattern of Chronic Kidney Disease in Antiretroviral-Naïve Patients with HIV/AIDS

Abstract

Background: Chronic renal failure and HIV/AIDS are both prevalent in Nigeria. We performed a cross-sectional analysis of renal function in newly diagnosed, treatment-naive HIV-infected patients before initiating highly active antiretroviral therapy. Methods: Treatment-inexperienced individuals were recruited. Patients with diabetes mellitus and hypertension were excluded. Plasma creatinine level was used to measure the estimated glomerular filtration rate ([eGFR] by Modification of Diet in Renal Disease equation). Predictors of creatinine and eGFR were determined by univariate and multivariate analyses. Results: We evaluated 183 patients. In all, 44 (24%) patients had a GFR <60 mL/min/1.73 m2, implying moderate chronic kidney disease (CKD). Considering the eGFR, 22 (12%) patients had stage 1, 117 (63.9%) stage 2, 13 (7.1%) stage 3, 27 (14.8%) stage 4, and 4 (2.2%) stage 5 CKD. Creatinine inversely correlated with CD4 (r = '.228, P =.025). CD4 predicts creatinine (odds ratio 1.6, 95% confidence interval 1.0-1.8, P =.003). Conclusion: In ART-naive patients, CKD is common, and low eGFR was associated with lower CD4 counts.
