Objective  To investigate the infection rates of toxin-producing Clostridium difficile and Candida albicans in patients with antibiotic-associated diarrhea (AAD) in West China Hospital of Sichuan University, analyze their clinical characteristics and make a survey of the therapy. Methods  Fecal specimens of AAD patients were collected in West China Hospital of Sichuan University from September 2014 to January 2015. Toxin-producing Clostridium difficile and Candida albicans were identified by polymerase chain reaction and then clinical data of cases was collected and analyzed. Results  Twenty-eight patients with Clostridium difficile infection were detected from the 126 AAD patients, 20 patients (15.9%) in whom were infected with toxin-producing Clostridium difficile. Type A+B+, type A-B+, and type A+B- accounted for 35.7% (10/28), 35.7% (10/28) and 28.6% (8/28), respectively. Fifty-four patients (42.9%) with yeast infection were detected. The predominant isolate was Candida albicans, accounting for 20.6% (26/126), and the others were Candida glabrata (n=11), Candida tropical (n=10), Candida parapsilosis (n=3), Saccharomyces cerevisiae (n=2), Pichia pastoris (n=1), and Kodamaea ohmeri (n=1). Toxin-producing Clostridium difficile strains and Candida albicans strains were both isolated from 3 patients (2.4%). The main antibiotics used in AAD ppatients were penicillins, carbapenems, third generation cephalosporins, and fluoroquinolones. AAD patients were all with underlying diseases at different degrees. The main treatments were probiotics and montmorillonite powder. Conclusion  The relatively high infection rates and complicated factors of AAD indicate that much more attention needs to be paid to the diagnosis and therapy of AAD by the clinical doctors.
