RESUMO
Purpose of study consists in determining of trypsin indices in blood serum--pancreatitis marker--with children by periods of virus A hepatitis (VAH). 104 children at the age of 3 - 14, being ill with a mild icteric form of VAH, were observed. 69 children were food-allergic (FA), 17 children had a burdened allergic history, 18 children had neither FA, nor burdened allergic history (control group). All children observed during VAH course were tested for trypsin indices in blood serum by radioisotope analysis (RIA). Similar laboratory tests were carried out with 15 healthy children--comparison group (standard). Children having FA and a burdened allergic history during VAH acuity, as judged by trypsin indices in blood serum, had a complication--pancreatitis (reactive). Children with FA during VAH recovery, had a retention of increased indices of trypsin in blood serum indicating a prolonged course of pancreatitis.
