Reports Outline HIV/AIDS Findings from National Institute of Allergy and Infectious Diseases (NIAID)


2013 DEC 30 (NewsRx) -- By a News Reporter-Staff News Editor at AIDS Weekly -- Data detailed on Immune System Diseases and Conditions have been presented. According to news reporting from Bethesda, Maryland, by NewsRx journalists, research stated, "Microalbuminuria is a marker for early kidney disease and cardiovascular risk. The purposes of this study were to determine the prevalence of microalbuminuria in an HIV-infected clinic population, to test the predictive value of a single urine albumin/creatinine ratio (ACR) to identify persistent microalbuminuria and to examine covariates of microalbuminuria."

The news correspondents obtained a quote from the research from the National Institute of Allergy and Infectious Diseases (NIAID), "We conducted a prospective cohort study of HIV-infected subjects (n=182) without proteinuria (urine protein/creatinine ratio ?0.5 g/g), elevated serum creatinine, diabetes, or chronic inflammatory conditions. Subjects completed three research visits within 9 months. Microalbuminuria was defined as the geometric mean ACR of 25-355 mg/g for females and 17-250 mg/g for males. The prevalence of microalbuminuria was 14%. The negative predictive value of a single urine ACR determination was 98%, whereas the positive predictive value was only 74%. Microalbuminuria was similar among Black (15%) and non-Black (14%) subjects (p=0.8). Subjects with microalbuminuria were more likely to have hypertension (p=0.02) and metabolic syndrome (p=0.03). While duration of HIV infection and the level of HIV viremia were similar between groups, those with microalbuminuria were more likely to have a CD4 count <200 cells/?l (p=0.0003). In a multivariate logistic regression analysis, the only significant independent predictors of microalbuminuria were low CD4 count (p=0.018) and current ritonavir exposure (p=0.04). The prevalence of microalbuminuria in an HIV-infected clinic population was similar to earlier reports, and was associated with hypertension and impaired immune function."

According to the news reporters, the research concluded: "A single normal ACR determination effectively excludes microalbuminuria, whereas an elevated ACR requires confirmation."
