Yersinia enterocolitica infection in children.
The clinical presentation, course and outcome of Yersinia enterocolitica infection was studied prospectively in 125 children. Enteric forms occurred in 114 children (92 enteritis, 20 pseudoappendicitis, 2 chronic ileitis), of whom 17 also had extramesenteric manifestations; 11 children had one or more extramesenteric forms without enteric disease. Enteritis occurred more frequently in young children whereas serious forms and extramesenteric forms were more common in children older than 6 years of age (P < 0.001). Arthritis was observed in 13 children and extensive lymphadenopathy in 11; 1 child had septicemia with pleurisy, 1 had vasculitis, 1 had cholecystitis and 4 had erythema nodosum. Diagnosis was established by positive culture in 100 (80%) children and by agglutinin test in 11 of 45 (24%), demonstration of circulating specific anti-IgA and anti-IgG to Yersinia outer membrane proteins in 47 of 48 (98%) and detection of antigen in biopsies in 28 of 33 (85%) children. The 2 latter methods were superior to the agglutinin test. Serotype O3 and O9 predominated. The frequency and seriousness of complications may justify the use of antibiotics for Yersinia enteritis in children 6 years of age or older.
