BACKGROUND: Renal disease in patients infected with HIV has evolved to include several lesions, including HIV-associated nephropathy (HIV-AN), which can promote progressive loss of renal function. Although angiotensin-converting enzyme inhibitors and corticosteroids are beneficial in selected patients, the effect of highly active antiretroviral therapy (HAART) on renal function is currently being explored. METHODS: We undertook a retrospective study to determine the types of renal lesions present in patients infected with HIV with renal insufficiency and/or proteinuria during the era of HAART availability and the effect of HAART on renal outcomes in these patients. Patients with HIV infection referred to the renal clinic from July 1996 through December 2000 were evaluated. Patient characteristics and data were collected including CD4 count, viral load, serum creatinine, blood pressure, proteinuria, renal ultrasound, and biopsy results, and treatment with HAART. Study endpoints were doubling of serum creatinine, initiation of dialysis, or death. RESULTS: Twenty-three patients met study criteria, 13 received HAART, and 10 did not. Baseline characteristics were similar except for renal function parameters, viral loads, and CD4 counts. A variety of lesions were noted on 12 renal biopsies. A clinical diagnosis of HIV-AN was made in the other 11 patients. Only 2 patients receiving HAART before renal evaluation were noted to have HIV-AN. In the HAART group, none of the patients, including those with HIV-AN, developed a doubling of serum creatinine. In the non-HAART group, all patients manifested a doubling of serum creatinine, 2 patients died, and 8 patients required dialysis. CONCLUSIONS: A variety of renal lesions are noted in patients infected with HIV during the HAART era. Patients who received HAART maintained stable renal function, whereas patients who did not required dialysis therapy or died with advanced renal failure. It seems that HAART may improve renal outcomes in patients with HIV and renal disease.
