Background:
Alcoholics have higher prevalence of hepatitis B virus (HBV) infection than non-alcoholics and such fact may influence in the development of liver cirrhosis and/or hepatocellular carcinoma.
Aim:
To evaluate the response to hepatitis B vaccine in alcoholics without liver cirrhosis.
Methods:
Twenty male alcoholics with mean age of 46.6 +/- 10.9 years were vaccinated; they ingested more than 80 g of ethanol/day for more than 10 years. As control group 40 male non-alcoholics with mean age of 37.8 +/- 9.7 years were also vaccinated. No serological evidence of contact with HBV, hepatitis C virus or human immunodeficiency virus was found among the subjects of both groups. The vaccine Euvax B (20 microg) was administered intramuscularly into the deltoid area at 0, 1 and 6 months. Serum anti-HBs were determined after one month of the last dose. Levels <10 mUI/mL were considered as non-response, between 10 and 99 mUI/mL as seroconversion, and > or = 100 mUI/mL as seroprotection.
Results:
No significant difference was found between alcoholics and controls, respectively, in the frequency of non-response (35.0% vs 32.5%), seroconversion (15.0% vs 15.0%) and seroprotection (50.0% vs 52.5%). Among responders, mean levels of anti-HBs in alcoholics (511 +/- 448 mUI/mL) were similar to the controls (696 +/- 410 mUI/mL). No negative interference on the response was associated with the body mass index, tabagism, being drinking or concurrent chronic pancreatitis without pancreatic insufficiency.
Conclusions:
Male alcoholics without liver cirrhosis had similar frequency and serum levels of anti-HBs to the non-alcoholics in response to HBV vaccination.
