Causes and outcomes of hepatic fibrosis in persons living with HIV.
Yen. Debra W DW; Sherman. Kenneth E KE
Key Findings
- HIV‑associated non‑alcoholic fatty liver disease (NAFLD) is common and linked to rapid fibrosis, especially with high visceral fat.
- Some antiretroviral drugs (e.g., integrase inhibitors) can cause weight gain, indirectly worsening liver fat accumulation.
- Tesamorelin and CCR5 blockers are highlighted as emerging therapies that may improve liver health in HIV patients.
Practical Outcomes
- If you have HIV and are concerned about liver health, keep an eye on body fat and discuss weight‑neutral ART options with your doctor. Tesamorelin may become a useful tool for reducing liver fat, but you’ll need to wait for more robust trial results before using it off‑label. Monitoring liver enzymes and fibrosis markers remains essential.
Summary
People with HIV often develop fatty liver disease that can lead to scarring, especially if they gain belly fat from some newer HIV meds. While many drugs can affect the liver, a growth‑hormone‑releasing peptide called tesamorelin looks promising for treating this fat‑related liver damage, but solid clinical data are still limited.
Abstract
The epidemiology of liver disease in people living with HIV has evolved since the arrival of effective hepatitis C virus (HCV) treatment. Nonalcoholic fatty liver disease (NAFLD) in HIV patients is highly prevalent while hepatitis D, hepatitis E, and occult hepatitis B remain underappreciated. We discuss mechanisms of fibrosis in HIV and review clinical outcomes of HIV-associated liver diseases. HIV-HCV co-infection is receding as a cause of progressive liver disease, but fibrosis biomarkers after HCV treatment remain elevated. Antiretroviral therapy (ART) with anti-hepatitis B virus (HBV) activity promotes stable liver disease, but oversimplifying ART regimens in unrecognized suppressed HBV may lead to activation of HBV. A high prevalence of fibrosis and rapid progression of fibrosis are seen in HIV-associated NAFLD, with visceral fat as a major risk factor. Newer ART such as integrase strand inhibitors may have limited intrinsic hepatoxicity but do increase weight, which may secondarily lead to hepatic steatosis. Promising therapies for HIV-associated NAFLD include tesamorelin and CCR5 blockade agents. Our understanding of the natural history and pathogenesis of liver diseases in HIV has advanced and adapted to the changing landscape of liver disease in this population. Future research should evaluate long-term clinical and histological outcomes, prevention strategies, and treatment options to improve morbidity and mortality in HIV-related liver diseases.
