[Gastrointestinal hemorrhage in children against a background of viral and bacterial infections].

In the process of intensive therapy, 22 of 32 patients developed gastrointestinal bleeding against the background of acute virobacterial pneumonia. The degree of intoxication, hypoxia, impairment in the coagulative blood system, and the level of circulating immune complexes were the main factors, which defined severity of the state of a patient, massiveness of bleeding and outcome of the treatment. The bleeding developed, if the DIC-syndrome achieved the stage of consumptive coagulopathy, and the content of the middle molecular mass substances and circulating immune complexes exceeded 1.5-2-fold the age indices.
