Insights
Effective HIV treatment has increased liver disease in patients. Viral hepatitis coinfections, drug toxicity, and alcohol contribute to liver damage, necessitating vaccinations like anti-HAV for those with HIV.
Area of Science:
- Hepatology
- Infectious Diseases
- Public Health
Background:
- Combined antiretroviral therapy transformed human immunodeficiency virus (HIV) into a chronic condition.
- Liver disease is a leading cause of death in HIV-infected individuals, often due to cirrhosis and hepatocellular carcinoma from hepatitis B and C coinfections.
- Antiretroviral drug toxicity, nonalcoholic fatty liver disease, alcohol consumption, and viral hepatitis E and A infections also contribute to liver injury in this population.
Purpose of the Study:
- To review the spectrum of liver diseases affecting individuals living with HIV.
- To highlight the increasing incidence of noncirrhotic portal hypertension.
- To emphasize the importance of vaccination against hepatitis A virus (HAV) in at-risk HIV-positive individuals.
Main Methods:
- Literature review and synthesis of existing research on liver disease in HIV-infected populations.
- Analysis of etiological factors contributing to liver morbidity and mortality.
- Evaluation of current recommendations for liver disease management and prevention in HIV.
Main Results:
- Hepatitis C virus and hepatitis B virus coinfections are primary drivers of mortality through cirrhosis and hepatocellular carcinoma.
- Alcohol consumption plays a significant role in liver injury.
- Noncirrhotic portal hypertension is an emerging concern, and acute/chronic hepatitis E and A infections are reported causes of liver damage.
Conclusions:
- HIV management has shifted focus towards managing chronic comorbidities, including liver disease.
- Comprehensive strategies addressing viral coinfections, drug toxicity, alcohol use, and vaccinations are crucial for improving outcomes in HIV patients.
- Anti-HAV vaccination is recommended for at-risk individuals living with HIV to prevent HAV-related liver damage.
Abstract:
Introduction of effective combined antiretroviral therapy has made human immunodeficiency virus (HIV) infection a chronic illness. Substantial reductions in the number of acquired immunodeficiency syndrome- (AIDS-) related deaths have been accompanied by an increase in liver-related morbidity and mortality. Liver diseases rank in the first three most-common causes of death in HIV-infected persons. Mortality is mainly due to cirrhosis and hepatocellular carcinoma induced by hepatitis C virus and hepatitis B virus coinfection. However, antiretroviral drugs toxicity also plays a role. Nonalcoholic fatty liver disease is a common cause of liver injury as well. Nevertheless, alcohol consumption probably plays a pivotal role. Noncirrhotic portal hypertension, an uncommon condition observed in less than 1% of patients, is increasingly described. Finally, acute hepatitis A virus (HAV) and acute and even chronic hepatitis E virus infection have also been reported as causes of liver damage in HIV. Anti-HAV vaccination is thus recommended in persons at risk living with HIV.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
