Abstract
OBJECTIVES
The aims of the present study were to estimate the prevalence of renal impairment (RI) among HIV-infected adult patients and to investigate the associated factors.
METHODS
A cross-sectional survey was conducted in a French hospital-based cohort. Clearance of creatinine (CC) was calculated using the Cockcroft-Gault formula. Four stages of RI were defined: mild (60-90 mL/min), moderate (30-60), severe (15-30) and end stage (<15). Logistic regression models were used to investigate factors associated with RI.
RESULTS
The male/female ratio of the 2588 patients enrolled was 3:1 and the median age was 42 years. At the time of assessment of CC, the median CD4 count was 430 cells/microL and HIV plasma viral load (VL) was<50 copies/mL in 60%. The overall prevalence of RI was 39.0%: 34.2% mild, 4.4% moderate, 0.3% severe and 0.2% end-stage. Mild RI was associated with female gender [odds ratio (OR)=3.3: 95% CI 2.6-4.3)], age >50 years (OR=9.8: 7.4-13.0) and 40-50 years (OR=1.9: 1.5-2.4), body mass index (BMI) <22 kg/m(2) (OR=3.3: 2.7-4.3) and tenofovir exposure (OR=1.4: 1.0-1.9 for <1 year and OR=1.5: 1.2-2.0 for >1 year). Advanced RI (CC <60 mL/min) was associated with age >50 years (OR=5.6: 2.9-10.9) and 40-50 years (OR=2.2: 1.1-1.4), BMI <22 kg/m(2) (OR=1.5: 1.0-2.4), hypertension (OR=2.5: 1.4-2.5) and indinavir (IDV) exposure >1 year (OR=2.3: 1.5-3.6).
CONCLUSION
This survey confirms the high prevalence of RI in HIV-infected patients and indicates the importance of the investigation of renal function especially in women, older patients, those with a low BMI or treated with tenofovir or IDV.
