Colonoscopic Fecal Bacteriotherapy in the Treatment of Recurrent Clostridium Difficile Infection - Results and Follow-up

Abstract Background. Vancomycin-resistant Enterococcus (VRE) is a major healthcare-associated pathogen and a well known complication among transplant and immunocompromised patients. We report on stool VRE clearance in a post hoc analysis of the Phase 2 PUNCH CD study assessing a microbiota-based drug for recurrent Clostridium difficile infection (CDI). Methods. A total of 34 patients enrolled in the PUNCH CD study received 1 or 2 doses of RBX2660 (microbiota suspension). Patients were requested to voluntarily submit stool samples at baseline and at 7, 30, and 60 days and 6 months after the last administration of RBX2660. Stool samples were tested for VRE using bile esculin azide agar with 6 µg/mL vancomycin and Gram staining. Vancomycin resistance was confirmed by Etest. Results. VRE status (at least 1 test result) was available for 30 patients. All stool samples for 19 patients (63.3%, mean age 61.7 years, 68% female) tested VRE negative. Eleven patients (36.7%, mean age 75.5 years, 64% female) were VRE positive at the first test (baseline or 7-day follow-up). Of these patients, 72.7%, n = 8 converted to negative as of the last available follow-up (30 or 60 days or 6 months). Of the other 3: 1 died (follow-up data not available); 1 patient remained positive at all follow-ups; 1 patient retested positive at 6 months with negative tests during the interim. Conclusions. Although based on a small sample size, this secondary analysis demonstrated the possibility of successfully converting a high percentage of VRE-positive patients to negative in a recurrent CDI population with RBX2660.

Background/Aim. In the last two decades the incidence of recurrent Clostridium difficile infection (CDI) has risen. The aim of this study was to determine the risk factors for the recurrent CDI among patients hospitalized with the initial CDI. Methods. We conducted a retrospective clinical trial at the Clinic for Infectious Diseases, Clinical Center of Vojvodina, Serbia, between January 2010 and January 2016. We enrolled 488 patients with the initial CDI who were treated with oral vancomycin (125 mg, 4 times per day) or oral metronidazole (400 mg, 3 times per day) for 10 days. After the completion of therapy, there was 60 days of the follow-up period for the assessment of the rates of relapse. To determine the risk factors for the CDI relapse, we compared the demographics, clinical and laboratory characteristics of the patients who had a relapse with the patients who had a stable clinical response. Results. Of the 488 cases, 29.09% recurred. The relapse occured in 22.72% patients who received vancomycin and in 36.60% patients treated with metronidazole (p = 0.038). A statistically significant effect on the CDI relapse had the comorbidities such as a malignancies (19.52% vs 8.82%, p = 0.023) and the postoperative CDI (25.67% vs 10.29%, p = 0.035), hipoalbuminemia (< 25 g/L) (70.27% vs 41.94%; p = 0.034) and the concomitant antibiotic therapy (50.67% vs 20.29%; p = 0.031). The persistence of C. difficile toxin in the stool at the end of treatment was registered in 22.32% of patients treated with metronidazole vs 9.09% of patients given vancomycin (p = 0.03). Conclusion. Our data suggest that the important risk factors for the CDI relapse are comorbidities (surgery within a month before developing CDI and malignancy), hipoalbuminemia (< 25g/L) and concomitant non-CDI antibiotics therapy. Vancomycin is more effective than metronidazole in the elimination of C. difficile toxins. The presence of C. difficile toxins in the stool after the successful completion of the initial CDI therapy does not affect significantly the occurrence of relapse.
