Prevalence of hepatitis B virus infection among alcoholic patients with liver disease
Insights
Hepatitis B virus (HBV) infection is more common in alcoholics with liver disease than in the general population. This suggests HBV may contribute to liver damage in alcoholics beyond alcohol
Area of Science:
- Hepatology
- Virology
- Gastroenterology
Background:
- Alcoholic liver disease is a significant health concern.
- The role of viral infections, specifically hepatitis B virus (HBV), in the pathogenesis of liver disease among alcoholics requires further investigation.
- Co-infection with HBV may influence the progression and severity of liver damage in individuals with a history of alcohol abuse.
Purpose of the Study:
- To investigate the prevalence of hepatitis B virus (HBV) infection in patients suffering from liver disease attributed to alcohol consumption.
- To determine if HBV infection plays a role in the development or exacerbation of liver damage in this patient group.
Main Methods:
- A cohort of 253 alcoholic patients with liver disease was studied over 15 months.
- Serological markers for hepatitis B virus (HBV) infection (HBsAg, anti-HBs) were assessed.
- Liver biopsy specimens from a subset of patients were analyzed for etiological factors.
Main Results:
- 31% of alcoholic liver disease patients exhibited serological evidence of past or present HBV infection.
- This prevalence was significantly higher compared to an age-matched control group.
- Among HBsAg-positive patients, liver biopsies often lacked clear signs of alcohol as the sole cause of liver damage.
Conclusions:
- Hepatitis B virus (HBV) infection is more prevalent in alcoholics with liver disease than previously recognized.
- The findings suggest that HBV may be a contributing or alternative etiological factor in liver disease among alcoholics.
- Alternative or co-existing etiologies, including HBV, should be considered in the diagnosis and management of liver disease in alcoholic patients.
Abstract:
The aim of this investigation was to elucidate a possible role of hepatitis B virus (HBV) in the pathogenesis of liver diseases in alcoholics. Two hundred and fifty-three alcoholics with liver disease were admitted to two medical departments in Copenhagen during a 15 months period. Seventy-nine patients (31%) showed serological signs (HBsAg, anti-HBs) of previous or active HBV infection. This is a significantly higher prevalence than found in an age-matched control population. Among the 79 patients with HBV markers, a total of 11 was found to be HBsAg-positive. From these 11 patients liver specimens were available for re-evaluation in nine cases. In only three of these liver biopsies, morphological changes indicating alcohol as the aetiological cause were found. In conclusion, different or concomitant aetiology must be considered in alcoholics with liver disease.
