Образцы кала собирали в возрасте 13–14 дней. У недоношенных, родившихся в сроки гестации от 22 до 28 нед, к возрасту 2 нед установлена легкой степени недостаточность поджелудочной железы, у недоношенных детей с гестационным возрастом 28–32 нед в этот же возрастной период активность панкреатической эластазы достигала значений доношенных детей. Установлена зависимость между степенью недостаточности поджелудочной железы и гестационным возрастом новорожденных. У недоношенных новорожденных, находившихся на искусственном вскармливании, активность фекальной эластазы была значительно ниже, чем у детей, получавших грудное и смешанное вскармливание. Обоснована необходимость раннего проведения у таких новорожденных заместительной терапии для предупреждения экзокринной недостаточности поджелудочной железы.</p></abstract><trans-abstract xml:lang="en"><p>We studied the activity of fecal elastase in 54 premature newborns of a gestation period of 22–32 weeks. The samples of feces were collected at the age of 13–14 days. Premature children born at gestational age of 22–28 weeks had pancreatic insufficiency of light degree by 2 weeks of age, preterm infants with a gestational age of 28–32 weeks by 2 weeks of age had the values of pancreatic elastase equal to that of full-term children. The authors have established the relationship between the degree of pancreatic insufficiency and the gestational age of newborns. Fecal elastase activity was significantly lower in premature infants who received milk mixtures as compared to breast-fed infants or infants with mixed feeding. The study substantiated the necessity of early replacement therapy in such newborns to prevent exocrine pancreatic insufficiency.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>недоношенные</kwd><kwd>гестационный возраст</kwd><kwd>характер вскармливания</kwd><kwd>фекальная эластаза</kwd><kwd>недостаточность поджелудочной железы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>premature</kwd><kwd>gestational age</kwd><kwd>the type of feeding</kwd><kwd>fecal elastase</kwd><kwd>pancreatic insufficiency</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">McClean P., Weaver L.T.
