title: Acute infective colitis caused by endemic pathogens in western Europe: endoscopic features.
abstract: In a 4-year period 45 patients were admitted to our gastroenterological u nit with acute infective colitis. The endemic pathogens responsible for the colitis were Yersinia enterocolitica (46%), Campylobacter fetus jejuni (20%), common Salmonellae (13%), less virulent strains of Shigella (9%), Entamoeba hystolytica (7%) and Cytomegalovirus (4%). These microorganisms caused very severe disease in 18% of the patients, who were mostly predisposed. While Salmonella- and amoebic colitis always mimicked ulcerative colitis by the presence of diffuse lesions, the other pathogens caused focal colitis, thus necessitating differential diagnosis vis a vis Crohn's colitis. Two patients (4%) died of complications, while 93% of the patients were cured by proper antimicrobial therapy. In the same period 12 patients were admitted with an acute attack of inflammatory bowel disease due to an intercurrent infection with the same pathogens. In most of these patients clinical remission of IBD was achieved by treating the intercurrent infection. These data indicate that in the presence of an acute attack of colitis an infective etiologic agent must always be sought, and that an attack of chronic idiopathic inflammatory bowel disease may be caused by an intercurrent infection.
