Hepatitis B vaccination in chronic alcoholics

Area of Science:

• Hepatology
• Immunology
• Vaccinology

Background:

• Hepatitis B virus (HBV) is linked to hepatocellular carcinoma.
• Alcoholics have a high prevalence of HBV infection.
• Preventing HBV infection in alcoholics is crucial.

Purpose of the Study:

• To assess the effectiveness of hepatitis B vaccination in alcoholic patients.
• To evaluate HBV vaccine response in patients with and without cirrhosis.

Main Methods:

• 32 cirrhotic patients received 3 or 4 doses of hepatitis B vaccine.
• Alcoholics without cirrhosis received 4 doses of hepatitis B vaccine.
• Antibody titers (anti-HBs) were measured at 6 months.

Main Results:

• No significant difference in vaccine response between 3- and 4-dose schedules in cirrhotic patients.
• 50% of cirrhotic patients showed no detectable anti-HBs.
• Alcoholics without cirrhosis had detectable anti-HBs, with a mean response of 97.7 +/- 4 SD.
• No difference in response based on sex, age, or alcohol intake status.

Conclusions:

• Alcoholic patients, especially those with cirrhosis, exhibit a deficient antibody response to hepatitis B vaccine.
• This impaired response may be specific to HBV vaccination and warrants further study.
• The findings suggest a potential link between HBV and liver damage in alcoholics that requires more research.
