Summary
This study details chronic hepatitis B (CHB) patient data from 1968-1988, revealing male predominance and common transmission routes. Chronic active hepatitis and liver cirrhosis were frequent, with some cases progressing to hepatocellular carcinoma.
Area of Science:
- Hepatology
- Virology
- Public Health
Context:
- Limited data on chronic hepatitis B (CHB) in the country, despite its high prevalence.
- CHB accounts for over 50% of all chronic hepatitis cases.
- Study period: 1968-1988, analyzing 164 CHB patients.
Purpose:
- To analyze epidemiological and clinical data of CHB patients.
- To understand transmission patterns and disease progression.
- To identify risk factors and outcomes in CHB.
Summary:
- 164 CHB patients (82.9% male) were studied; transmission routes included unknown (55%), vertical, and sexual. Commercial gammaglobulin was a suspected source in 8 cases.
- Chronic active hepatitis (43.9%) and liver cirrhosis (32.3%) were most common. HBeAg was predominant (66.4%).
- Progression from chronic lobular/persistent hepatitis to chronic active hepatitis and cirrhosis was observed. Hepatocellular carcinoma developed in 4.9% of patients.
Impact:
- Highlights the significant burden of CHB and its common clinical manifestations.
- Provides insights into disease progression and potential iatrogenic transmission.
- Informs public health strategies and clinical management of CHB.
