Excess alcohol consumption is associated with numerous metabolic changes and homeostasis disturbances of many macro- and micro-elements in the body. It has been associated with multiple pathologies at all levels. In the digestive apparatus, alcohol has generally been related to its toxic effects upon the liver. Alpha-1 antitrypsin (α-1 AT or AAT) plays an important role in controlling inflammation, coagulation and repair mechanisms in the body and most α-1 AT in the body is produced by the liver; from the other hand, Intrinsic factor (IF), which is a glycoprotein produced by the parietal cells of the stomach is necessary for the absorption of vitamin B12 in the small intestine. This study was designed to assess serum levels of α-1 AT and anti-IF Abs (IgG) among heavy alcoholics to clarify the relationship between alcohol addiction and such liver and/or stomach disorders. Fifty-four consecutive alcohol-dependent males were enrolled as a target group and 30 age matched males were considerate as a control group. The level of alpha-1 antitrypsin (α-1 AT) and anti-intrinsic factor (IF) antibodies were investigated by single radial immunodiffusion (SRID) and enzyme-linked immunosorbent assay (ELISA) respectively. We found from a total of 54 alcoholic patients that the mean age of patients is 37.5 years with a progressive increase in cases at third decade of age. They reported an average addiction period of more than 18 years. Most patients (93%) were currently smoking; and 18.5% were psychiatric; about 9% of them used to have co-addictions like heroin, valium and artin; another 9% had multiple sclerosis. We observed a non significant decrease of α-1 AT levels in alcoholics compared to control group (p>0.05), while there was a high significant increase in the level of anti-IF Abs in alcoholics, sera compared with control group (p<0.05). Furthermore; the serum level of α-1 AT and anti-IF Abs in alcoholic group are not related to age of starting consumption of alcohol. Specifically, we found no significant differences in the levels of α-1 AT and anti-IF Abs between those who start drinking prior to age 18 years (N=32), and after age 18 years (N=22) p>0.05. On the other hand; there is a statistically significant correlation between α-1 AT levels and the duration of alcohol consumption (p<0.05); similarly; theere was a highly significant correlation between the levels of anti-IF Abs and the duration of alcohol consumption was observed (p<0.05).The results suggest that Excess alcohol consumption is associated with numerous metabolic changes and homeostasis disturbancesof many macro- and micro-elements in the body. It has been associated with multiple pathologies at all levels.
