Assessment of Vascular Function in Patients With Chronic Kidney Disease
Published on: June 16, 2014
Insights
Chronic kidney disease (CKD) is a common complication in HIV patients. Early detection and access to antiretroviral therapy (ART) improve kidney function, survival rates for dialysis, and transplant outcomes.
Area of Science:
- Nephrology
- Infectious Diseases
- HIV Medicine
Background:
- Chronic kidney disease (CKD) is a significant complication of HIV infection.
- HIV-associated nephropathy (HIVAN) and HIV-immune complex disease are key renal manifestations.
- The advent of antiretroviral therapy (ART) has altered the landscape of HIVAN, increasing focal segmental glomerulosclerosis prevalence.
Purpose of the Study:
- To review the impact of HIV infection on kidney health.
- To discuss the role of antiretroviral therapy (ART) in managing HIV-related kidney disease.
- To highlight the importance of early detection and management strategies for CKD in HIV-positive individuals.
Main Methods:
- Literature review of studies on HIV and kidney disease.
- Analysis of the effects of ART on renal function in HIV patients.
- Examination of outcomes for HIV-positive patients undergoing dialysis or kidney transplantation.
Main Results:
- ART has led to a decline in HIVAN incidence and improved overall kidney function.
- HIV-positive patients on ART show comparable survival rates on dialysis and successful outcomes with kidney transplantation.
- Many antiretroviral drugs require dose adjustment in patients with CKD.
Conclusions:
- Early screening for kidney disease upon HIV diagnosis and annually is crucial.
- Access to ART and preventative HIV programs are essential for reducing the burden of CKD in HIV.
- Kidney transplantation and dialysis are viable options for HIV-positive patients with advanced kidney disease.
Abstract:
Chronic kidney disease (CKD) is a frequent complication of HIV infection. The classic involvement of the kidney by HIV infection is HIV-associated nephropathy (HIVAN), occurring typically in young adults of African ancestry with advanced HIV disease in association with APOL1 high-risk variants. HIV-immune complex disease is histologically the second most common diagnosis. With the introduction of antiretroviral therapy (ART), there has been a decline in the incidence of HIVAN, with an increasing prevalence of focal segmental glomerulosclerosis. Several studies have demonstrated overall improvement in kidney function with initiation of ART. Many antiretroviral medications are partially or completely eliminated by the kidney and require dose adjustment in CKD. HIV-positive patients requiring either hemo- or peritoneal dialysis, who are stable on ART, are achieving survival rates comparable to those of dialysis patients without HIV infection. Kidney transplantation has been performed successfully in HIV-positive patients; graft and patient survival is similar to that of HIV-negative recipients. Early detection of kidney disease by implementation of screening on diagnosis of HIV infection and annual screening thereafter will have an impact on the burden of disease, together with access to ART. Programs for prevention of HIV infection are essential.
