Abstract
BACKGROUND & AIMS: Clostridium difficile is recognized as the major cause of nosocomial gastroenteritis usually related to antibiotic treatment. Although treatable, C. difficile--associated disease (CDAD) tends to recur in many patients. The purpose of the study was to analyze the risk factors for recurrence in patients with CDAD after the first treatment with vancomycin, metronidazole or both.
METHOD: We conducted a retrospective study of all patients admitted to the Teaching Hospital of Infectious Diseases Cluj-Napoca, Romania, between January 2011 and October 2012 with the diagnosis of CDAD or who developed diarrhoea after admission. A clinical diagnosis was made and culture and toxin A and B detection were carried out. We performed a statistical analysis taking into consideration: age, gender, previous hospital exposure, previous antibiotic treatment, and treatment duration. The patients were followed-up for at least 60 days.
RESULTS: We included 306 patients (177 women and 129 men) with a median age of 71 years; 208 patients (68%) had prior hospitalization and 195 (64%) had received prior antibiotic treatment. Actual treatment consisted of vancomycin in 76 (25%) patients, metronidazole in 132 (43%) and both combined in 98 (32%) patients. The average duration of treatment was 10 days. Sixty patients (20%) experienced 95 recurrences and 9 patients died (3%). Treatment with metronidazole, vancomycin or both for 10 or more days did not prevent recurrences. Age over 70 (RR 1.5, CI 95%: 1.055-2.71) and use of PPI (RR 1.3, CI 95%: 1.16-3.1) significantly increased the risk of first recurrence of CDAD.
CONCLUSIONS: CDAD recurrence rates were similar to those reported in the literature. The risk of first recurrence was significantly higher in patients older than 70 who also received PPI treatment.
