Abstract

Background and objectives: HIV-infected patients often undergo kidney biopsy. The risks of percutaneous ultrasound-guided kidney biopsy in this population are not well established. Design, setting, participants, & measurements: This was a case-control, single-center study of 1116 (243 with HIV infection and 873 without) consecutive ultrasound-guided biopsies from 1024 patients. The primary outcome was any major or minor complication. Major complications included biopsy-associated bleeding that required transfusion, angiography, or surgery; hypotension that required intervention; and death. Minor complications included development of a hematoma or gross hematuria. The odds of complication was assessed with logistic regression. Results: Overall complication rates (8.6 versus 7.2%) did not significantly differ between HIV-infected and noninfected individuals. HIV-positive status did not predict complication. In the entire cohort, hepatitis C infection was associated with a 2.08 (95% confidence interval [CI] 1.47 to 2.93) increased odds of complication, and each 10,000-cells/mm3 decrease in prebiopsy platelet count a 1.05 (95% CI 1.02 to 1.08) increased odds of complication. In addition, prebiopsy hematocrit <30% and estimated GFR <30 ml/min per 1.73 m2 were associated with major complication. Whereas the association of prebiopsy platelet count was not modified by HIV infection, hepatitis C/HIV co-infection was associated with a 5.71 (95% CI 1.89 to 17.2) increased odds of complication as compared with 1.27 (95% CI 0.73 to 2.19) in hepatitis C-positive/HIV-negative individuals. Conclusions: Ultrasound-guided percutaneous kidney biopsy is a relatively safe, well-tolerated procedure in the HIV-infected population. HIV-infected individuals who are co-infected with hepatitis C seem to be at greatest risk.
