Liver affection associated with Yersinia enterocolitica infection.

During the last ten years, several clinical manifestations of Yersinia enterocolitica infection have been reported. Surgeons are especially aware of "the right iliac fossa syndrome", caused by mesenterial lymphadenitis and terminal ileitis. We suggest that Yersinia enterocolitica may also cause a clinical condition easily misinterpreted as cholecystitis, and accompanied by slightly elevated serum levels of ASAT, LD, AP and bilirubin. Apparently, this condition may run a chronic relapsing course. A report is given of two cases of liver affection associated wtih positive Y. ent. antibody titre. Case 1 would illustrate the chronic relapsing liver affection with stationary titre. In Case 2 an acute Au-negative hepatitis is accompanied by significant rise and fall in titre.
