ABSTRACT
BACKGROUND:
The prevalence and factors associated with an increased risk of renal dysfunction in HIV-infected patients receiving or not receiving antiretroviral therapy (ART) have been poorly evaluated in observational settings.METHODS:
Patients in the ICONA Foundation cohort with at least two creatinine values available while still ART-naïve were enrolled in the study. A logistic regression analysis was performed to identify predictors of an estimated glomerular filtration rate (eGFR)<90 mL/min/1.73 m(2) at baseline. The incidence and predictors of a >20% reduction in eGFR from pre-combination ART (cART) levels (or a decrease from ≥90 to <90 mL/min/1.73 m(2) ) were evaluated by Poisson regression.RESULTS:
A total of 1505 patients were included in the study; 363 (24%) had eGFR<90 mL/min/1.73 m(2) at baseline. Older patients [odds ratio (OR) 1.58 per 10 years older; P<0.00001], female patients (OR 2.41 vs. male patients; P<0.00001), those who had diabetes and/or hypertension (OR 2.36 vs. neither; P<0.03) and patients with higher baseline CD4 count (OR 1.06 per 100 cells/µL higher; P<0.03) showed a greater risk of eGFR<90 mL/min/1.73 m(2) . Ninety-six patients experienced an eGFR decrease of >20% from pre-cART levels (6.8 per 100 person-years). Older age [relative risk (RR) 1.41 per 10 years older; P=0.005], female gender (RR 2.25 vs. male; P=0.003) and current exposure to didanosine (ddI), tenofovir and protease inhibitors were the major determinants.CONCLUSIONS:
We observed a relatively high rate of mild renal dysfunction in the absence of ART. In addition to traditional risk factors such as older age and diabetes/hypertension, female gender and current use of ddI, tenofovir and protease inhibitors were associated with a greater risk of decreased renal function as measured by eGFR.
