Chronic active hepatitis at Baragwanath Hospital
Summary
This study identified four main causes of chronic active hepatitis (CAH) in Black South African patients: autoimmune, drug-induced, hepatitis B virus-related, and alcohol-related. Autoimmune causes were most common, while alcohol-related CAH occurred only in males.
Area of Science:
- Hepatology
- Immunology
- Public Health
Background:
- Chronic active hepatitis (CAH) is a significant liver condition with diverse etiologies.
- Understanding the etiological landscape of CAH in specific populations is crucial for targeted interventions.
- Previous studies on CAH in South African Black populations are limited.
Purpose of the Study:
- To retrospectively analyze the etiological categories of chronic active hepatitis (CAH) in Black patients at Baragwanath Hospital, Johannesburg.
- To identify the prevalence and clinical characteristics of different CAH subtypes within this demographic.
- To assess the occurrence of CAH in relation to common risk factors in the South African Black population.
Main Methods:
- Retrospective analysis of 35 Black patients diagnosed with chronic active hepatitis (CAH) between 1972 and 1980.
- Categorization of CAH based on etiological factors: autoimmune, drug-induced, hepatitis B virus (HBV)-related, and alcohol-related.
- Clinical data review including presenting symptoms, systemic features, liver status, and presence of cirrhosis.
Main Results:
- Four major etiological categories were identified: autoimmune (57%), drug-induced (17%), HBV-related (14%), and alcohol-related (11%).
- Alcohol-related CAH was exclusively observed in males, presenting with upper abdominal pain.
- Autoimmune CAH frequently presented with systemic features like skin rashes and congestive cardiac failure; jaundice was common in other types. Cirrhosis was present in approximately 50% of patients.
- Hepatitis B virus-related CAH showed an absence of tissue non-specific auto-antibodies.
Conclusions:
- Autoimmune factors represent the predominant cause of chronic active hepatitis (CAH) in this cohort of Black South African patients.
- Despite the prevalence of risk factors like hepatitis B infection and alcohol abuse, CAH remains relatively uncommon in South African Blacks.
- Clinical presentation varies significantly among etiological subtypes, aiding in differential diagnosis.
