PurposeThis study was designed to determine if (1) alcoholics have a higher prevalence of hepatitis B virus (HBV) serologic markers than do non-alcoholic controls and (2) if they respond to hepatitis B vaccination in a manner similar to that of non-alcoholic controls.Patients And MethodsThe study was designed as a case-control study, and 129 Alaska Natives were recruited. Alcoholics were recruited from inpatient wards, outpatient clinics, a soup kitchen serving the homeless, and several alcohol rehabilitation centers; control subjects were recruited primarily from among Alaska Native Hospital employees. A standardized questionnaire, the Alcohol Dependency Scale (ADS), was administered to all participants. Each participant was screened for hepatitis B serologic markers, had liver function studies performed, and was examined for evidence of liver disease. Participants seronegative for HBV markers received three doses of hepatitis B vaccine. Linear regression analysis was performed to compare the amount of alcohol intake and variables associated with liver disease with the response to hepatitis B vaccination and antibody levels achieved. Using an ADS score of greater than 13, 64 participants were classified as chronic alcoholics, and 60 were classified as controls.ResultsHBV seropositivity was found in 22 alcoholics (34.4%) and seven controls (11.7%). After adjusting for age and sex, this difference was significant (chi 2 MH = 6.57, df = 1; p = 0.012). Abnormal levels of liver transaminase occurred significantly more often in alcoholic participants than in control subjects (chi 2 MH = 4.91, df = 1; p = 0.026). Of 95 seronegative persons, 72 received three doses of hepatitis B plasma-derived vaccine. Alcoholic subjects and control subjects did not differ significantly in their response to vaccination. Only four alcoholics and two controls did not develop antibody to hepatitis B surface antigen (anti-HBs) after hepatitis B vaccination, and two alcoholics and three controls had anti-HBs levels less than 10 SRU by radioimmunoassay. Mean anti-HBs levels measured in milli-international units (mIU) for the 62 responders showed a decrease in the anti-HBs level with increasing age (p less than 0.001). There was no difference in the mean anti-HBs log10 mIU between alcoholics and controls younger than 45 years of age, but in persons greater than 45 years of age, alcoholics had a lower mean anti-HBs log10 mIU level than did controls; this difference, however, was not significant (p greater than 0.10).ConclusionChronic alcoholics have a higher prevalence of HBV seromarkers than do age-matched controls. Seronegative alcoholics, especially those under age 45, respond well to hepatitis B vaccination, and such vaccination should be considered in all chronic alcoholic persons.
