    Abstract:
    In 3 divisions of internal medicine of teaching hospitals of the Comprehensive Hospital Drug Monitoring (CHDM) Foundation Bern/St Gallen, 42,920 patients consecutively admitted between 1974-1991 were investigated for adverse drug reactions. Of these 16,150 patients (38%) had received at least one systemically administered antibacterial drug during the hospital stay. Antibiotic-associated colitis included the following diagnoses: pseudomembranous colitis, hemorrhagic colitis and milder forms of colitis. We collected the data of these patients by searching for all diagnoses which might represent antibiotic-associated colitis (from the list of WHO adverse drug reaction terminology). 9 individual patients with one episode of probable antibiotic-associated colitis were found. In 5 of these cases, only one drug given during the hospital stay seemed to be implicated. An additional 32 patients were admitted with antibiotic-associated colitis in relation to treatment with the same groups of drugs before hospital admission. Based on the exposure pattern of the 9 patients with antibiotic-associated colitis compared to all patients exposed during hospital stay, we estimated the following frequencies related to the drug groups with at least 1,000 patients exposed: for all antibacterial chemotherapeutics 0.6/1000 (0.25-1.06); all penicillins 0.6/1000 (0.22-1.32), for benzyl-, phenoxy-, ureido-, isoxazolyl penicillins and methicillin 2.0/1000 (0.42-5.92) and aminopenicillin or analogues, with or without clavulanic acid 0.6/1000 (0.18-1.35). For cephalosporins the frequency is 1.4/1000 (0.17-5.12). Under sulfonamides combined with trimethoprim or related substances (5077 exposed patients) and fluoroquinolones (1043 exposed patients) no case was observed.(ABSTRACT TRUNCATED AT 250 WORDS)
