Human immunodeficiency virus infection and the liver

Area of Science:

• Hepatology and Virology
• Immunology and Infectious Diseases

Background:

• Liver disease spectrum in HIV-infected individuals ranges from abnormal liver function to cirrhosis, non-alcoholic steatohepatitis, and hepatocellular cancer.
• HIV infection directly impacts liver cells, causing apoptosis, activation, and fibrosis.
• HIV alters gut permeability, increasing lipopolysaccharide, which affects liver function.

Purpose of the Study:

• To review recent changes in the epidemiology of liver disease in HIV-infected patients.
• To explore the pathogenesis and clinical presentation of liver disease in HIV, excluding viral hepatitis co-infections.
• To focus on liver disease issues pertinent to low and middle-income countries.

Main Methods:

• Literature review of recent studies on liver disease in HIV-infected individuals.
• Analysis of epidemiological data, focusing on pathogenesis and clinical manifestations.
• Specific consideration of factors relevant to low and middle-income country contexts.

Main Results:

• HIV infection contributes to a wide range of liver pathologies, including non-alcoholic fatty liver disease and hepatocellular carcinoma.
• Direct HIV infection of hepatocytes and altered gut permeability are key pathogenic mechanisms.
• Epidemiological patterns and clinical presentations are evolving, with significant implications for resource-limited settings.

Conclusions:

• Liver disease remains a critical concern for HIV-infected individuals, necessitating ongoing research and clinical attention.
• Understanding the specific pathogenesis and epidemiology is crucial for effective management, especially in low and middle-income countries.
• Further research is needed to address the unique challenges of liver disease in HIV patients within these regions.
