The prevalence of gastric autoantibodies in chronic alcoholics.Am J Gastroenterol. 1975 Sep; 64(3):187-90.AJ
One hundred fifty alcoholic men and women and 150 age and sex-matched nonalcoholic controls (after exclusion of pernicious anemia and cancer of the stomach) were evaluated for the presence of parietal cell antibodies (PCA). Blocking and binding intrinsic factor antibodies (IFA) were determined in the PCA positive sera. The prevalence and age and sex distribution of PCA in the alcoholics and nonalcoholics was identical. In alcoholics above the age of 60 years, the incidence of PCA, although higher than in those of the younger age group was similar to that in the nonalcoholics of the same age group (in men 6.3 percent and 7.3 percent and in women 7.5 percent and 10.0 percent respectively). Antral gastritis of moderate or severe degree was the frequent lesion in alcoholics. This form of gastritis was not associated with any significant increase in the incidence of PCA. No patients with sera positive for IFA were detected among the 22 PCA positive patients. There is no evidence for humoral derangement of the gastric autoimmunity in chronic alcoholics.
