Popis: Experimental pancreatitis can be induced by an ethionine-containing, choline-deficient diet in mice. We investigated the role of circulating alpha 1-antitrypsin in this model using two strains of mice: ICR and C57BL-6. A 50% reduction in circulating alpha 1-antitrypsin occurred in all mice by day three of diet exposure. Total protein was reduced by only 9% and albumin was unchanged. Female mice of both strains had significantly lower alpha 1-antitrypsin levels than male mice prior to and after diet exposure. This was associated with significantly greater mortality in both female strains. Interstrain comparisons showed a significantly higher mortality in the C57BL-6 females (100%) compared to the ICR females (58%); this corresponded to significantly lower alpha 1-antitrypsin levels in C57BL-6 females. Regardless of sex or strain, alpha 1-antitrypsin levels prior to and after diet exposure were significantly higher in mice surviving than in mice dying. We conclude that circulating alpha 1-antitrypsin is a predictor of mortality from diet-induced pancreatitis.
