Incidence of microalbuminuria in ambulatory patients with acquired immunodeficiency syndrome.
Nephropathies associated with human immunodeficiency syndrome (HIVAN) are characterized by gross proteinuria, lack of change in blood pressure, and various histologic lesions. The present study prospectively measured microalbuminuria in 72 HIV-seropositive patients (3 asymptomatic, 32 AIDS-related complex, 37 AIDS) screened for Phase I clinical pharmacology studies. There were 14 patients (19.4%) that had abnormal urinary levels of microalbumin; 7 of these patients (50%) had proteinuria similar to those values found in diabetic nephrotic syndrome. Microalbumin levels were not correlated with race, sex, risk factors of AIDS, disease history, or concurrent drug therapy. In contrast, urinary microalbumin levels were correlated with CD 4 T-cell and WBC counts, tumor necrosis factor alpha and beta 2-microglobulin levels, suggesting an association between AIDS progression and microalbuminuria. By monitoring urinary microalbumin levels, those patients susceptible to the development of nephrotic syndrome could be identified and prophylactic measures initiated.
