Abstract
The aim of the present study was to further elucidate acute and chronic manifestations of Yersinia enterocolitica infection. During the period 1974–83, 458 hospitalized patients were diagnosed by antibody response and/or isolation of the microorganism. 64 patients had suffered from chronic conditions as rheumatic disease, inflammatory bowel disease, hepatitis, nephritis or thyroid disease for some time. Acute hepatic, renal, cardiac, pulmonary, pancreatic or neurologic involvement were observed in a substantial portion of patients; several had multiorgan disease. Acute insulin-dependent diabetes was seen in 2 patients, malignant mesothelioma in 2, and specific lymph node inflammation in 1. The patients were followed for 4–14 years (1987). 36/160 readmitted patients had abdominal pain and 26 had diarrhea; chronic colitis was demonstrated in 4. Some patients developed rheumatic conditions; others developed chronic disease of liver, kidneys, heart, pancreas, thyroid or nervous system. Chronic liver disease, in 22 patients, was correlated with positive tests for antinuclear antibody and rheumatoid factor; and might influence development of malignant disease, and mortality. A variety of acute and chronic clinical pictures may be associated with Y. enterocolitica infection, and further clinical research is required in this field.
