Proteinuria and Albuminuria among a Global Primary CVD Prevention Cohort of PWH: Prevalence and Associated Factors

Objective(s): To determine baseline prevalence of proteinuria and albuminuria among REPRIEVE participants and evaluate associated risk factors. Design: Cross sectional analysis of a baseline sample of participants from the REPRIEVE Trial. Methods: REPRIEVE is an international primary cardiovascular prevention RCT of pitavastatin calcium vs. placebo among PWH on antiretroviral therapy. A representative subset (2791 participants) had urine collected at study entry. Urine protein to creatinine ratios (uPCR) and albumin to creatinine ratios (uACR) were classified as normal, moderately increased and severely increased. These were dichotomized to Normal or Abnormal for log-binomial regression analysis. Demographic, cardiometabolic, and HIV-specific data were compared among those with normal versus abnormal results. Results: Overall, median age 49 years, 41% female sex, 47% black or African American race, 36% had eGFR <90 mL/min/1.73mm². For uPCR, 27% had moderately or severely increased values. For uACR, 9% had moderately or severely increased values. In the fully adjusted model for proteinuria, female sex, older age, residence in sub-Saharan Africa or East Asia, lower BMI, lower CD4 cell count, and use of TDF were associated with abnormal values. In the fully adjusted model for albuminuria, a diagnosis of HTN was associated with abnormal values. Conclusions: Abnormal proteinuria and albuminuria remain common (27% and 9%) despite controlled HIV. Lower current CD4 count and TDF use were strongly associated with proteinuria. Certain modifiable comorbidities, including HTN and smoking, were associated with abnormal values. In PWH with preserved eGFR, urine measures identify subclinical kidney disease and afford the opportunity for intervention.
