Résumé

BACKGROUND: Cardiopulmonary bypass (CPB) initiates an inflammatory cascade, predisposing the patient to a number of infections. The stress of surgery and anaesthesia further expose the patient to a variety of non-infectious complications. We report a group of patients who developed granulomatous disease after open heart surgery. METHODS: We retrospectively analysed a subset of patients who developed a syndrome of fever, jaundice and hepatomegaly after open heart surgery. We recruited age- and sex-matched controls who underwent open heart surgery during the same period (July 2002-July 2004). Details of demographic profiles, diagnostic evaluation and drug treatment were noted and compared between the two groups using the SPSS software. RESULTS: Five patients were identified to have the specific syndrome of high grade intermittent fever with jaundice and hepatomegaly with investigations revealing an intrahepatic cholestasis. A detailed evaluation revealed granulomas in tissue specimens of the bone marrow and/or liver in these patients. An extensive evaluation for an alternative aetiological agent was non-contributory. CONCLUSION: We found granulomatous hepatitis in 5 patients following open heart surgery and they were given conventional antituberculous therapy to which they responded. It is possible that in these patients, tuberculosis was re-activated from a dormant focus due to a period of transient immunodeficiency caused by an extracorporeal circulation.
