[Genetic susceptibility to pancreatitis].
Pancreatitis is a complicated polyetiological disease rather frequently met with. Inflammatory degenerative changes in the pancreas are the underlying cause of the condition which in acute cases may give rise to irreversible pancreonecrosis, and in chronic ones--to fibrosis development and severe pain syndrome. Of utmost importance is the patient's genetic susceptibility to pancreatitis. The purpose of the study is to assay the role of genetic factors involved in the etiopathogenesis of pancreatitis. The interest focused on alpha1 antitrypsin (alpha 1 AT) arises from the fact that its mutant forms are implicated in the destructive processes within the organism. The reduced inhibitory activity of alpha 1 AT enhances the action exerted by the proteolytic enzymes--trypsin and chymotrypsin [correction of hemotrypsin]. Impairment of the balance between proteases and their inhibitors plays certain role in pancreatitis development. Seventy patients, 44 men and 26 women, are covered by the study, with 42 of them presenting acute pancreatitis, and 28--chronic relapsing form. A high rate of alpha 1 AT mutant genes carrier state is established--14.28 per cent, exceeding statistically significantly the incidence of alpha 1 AT variants in the Bulgarian population--4.95 per cent (p < 0.01). In acute pancreatitis patients the incidence of alpha 1 AT variants is 2.38 per cent, and in chronic forms--32.14 per cent. In pancreatitis patients alpha 1 AT deficit brings about genetic predisposition to serious complications, e.g. chronification of the process. Individual therapeutic approach is mandatory, with Kontrikal used in chronic relapsing pancreatitis in the form of substitutive medication, and in acute pancreatitis--according to judgement depending on the clinical picture and laboratory findings.
