Collagenous enteritis as a rare cause of exudative enteropathy in a child. Case report

Exudative enteropathy (EE) syndrome can be associated with various diseases of the gastrointestinal tract (GIT) and is manifested by edematous syndrome, hypoproteinemia, hypoalbuminemia, lymphocytopenia, hypogammaglobulinemia, and an increase in the level of α-1-antitrypsin in the feces. More than 60 medical conditions are associated with loss of protein through the gastrointestinal tract, including erosive-ulcerative diseases of the gastrointestinal tract, non-erosive lesions of the mucous membrane causing an increase in the permeability of the intestinal wall, as well as disorders with an increase in pressure in the lymphatic system. Correct diagnosis and timely replacement and pathogenetic therapy are essential for the rapid cessation of pathological losses, the recovery of the proteinogram, and the prevention of life-threatening complications. Collagenous enteritis is one of the rare diseases of the small intestine associated with EE syndrome. The article presents a clinical case of a young child with EE and collagenous enteritis. The stages of the diagnostic workup in detecting EE syndrome in the child are discussed, and the pathogenetic factors that determined the development of this disorder are considered.
