Optimal Management of HIV Infected Adults at Risk for Kidney Complications in Nigeria

April 15, 2024 updated by: C. William Wester, Vanderbilt University Medical Center
In this study, the Investigators plan to determine the optimal means to prevent or slow the progression of kidney disease among genetically at-risk northern Nigerian HIV-infected adults. Based on data from studies of diabetic kidney disease that used medications that block the renin angiotensin aldosterone system (RAAS), we plan to evaluate whether or not RAAS inhibition (using a widely available medication that blocks RAAS) in HIV-infected adults produces similarly promising results.

Study Overview

Detailed Description

Individuals of African descent have a much higher risk for glomerular diseases. Specifically, there are two risk variants in the chromosome 22 APOL1 gene (G1/G2) and persons possessing 2 copies of these risk variants (G1/G1, G1/G2, or G2/G2), referred to as the high-risk (HR) genotype, are at high risk for non-diabetic kidney disease. Kopp et al. have shown that the APOL1 high-risk genotype confers sizeable odds ratios (OR) for FSGS (OR = 17), HIVAN (OR = 29 in the US; 89 in S. Africa), and hypertension-attributed end stage kidney disease (OR = 7). The presence of these risk variants is highest in West Africa, and specifically in Nigeria among persons of Hausa, Fulani, and Igbo descent. In the setting of untreated HIV infection, we have estimated that ~50% of individuals carrying the APOL1 HR genotype will develop chronic kidney disease (CKD). However, there is limited availability of dialysis and kidney transplantation in Nigeria, and most individuals will die soon after developing ESKD. Markers of kidney disease include microalbuminuria, proteinuria, and/or reduced estimated glomerular filtration rate (eGFR). All 3 have been associated with increased mortality in HIV+ adults. Increased urinary albumin excretion has diagnostic and prognostic value in the identification and confirmation of renal disease, and changes in albuminuria can be useful in assessing treatment efficacy as well as disease progression. Microalbuminuria, i.e., urine albumin to creatinine ratio (uACR) in the 30-300 mg/g range, is likely the earliest stage of CKD, analogous to diabetic microalbuminuria. The renin-angiotensin aldosterone system (RAAS) is the central player in the pathophysiology of CKD and blocking RAAS with angiotensin converting enzyme inhibitors (ACEi) is a well-recognized strategy to slow or halt renal disease progression in diabetics with CKD. To determine whether the presence of APOL1 HR genotype alters or predicts responsiveness to conventional therapy and if the addition of an ACEi to standard antiretroviral therapy (ART) reduces the risk for renal complications among West African adults, we will screen 2,600 HIV+ ART-experienced adults; to conduct the following Specific Aims:

  1. To determine the prevalence of APOL1 renal risk variants and assess whether APOL1 HR status correlates with prevalent albuminuria, eGFR, and/or prevalent CKD in a West African population.
  2. To assess whether RAAS inhibition (with the ACEi lisinopril) in addition to ART, compared to the existing standard-of-care (SOC), will significantly reduce the incidence of additional kidney disease manifestations. We will randomize ART-experienced (6+ months) adults with prevalent microalbuminuria (uACR 30-300 mg/g) and an eGFR of > 30 ml/min/1.73m2 to lisinopril (n=140) vs. SOC (n=140); and
  3. To determine whether the APOL1 HR genotype is associated with worse longitudinal renal outcomes in Nigerians with prevalent albuminuria.

WHOQOL-HIV scale evaluates quality of life based on physical, psychological, social, environmental, and spiritual domains, as well as level of independence. We will use the 31-question version, with each question rated on a 5-point Likert scale. Scores of questions within each domain are averaged to get domain score, and final score is mean of domain scores multiplied by 4. Final score ranges from 4 to 20, with 20 being optimal.
