Abstract
BACKGROUND Faecal microbiota transplantation (FMT) is a highly effective approach for refractory and recurrent Clostridioides difficile infection (CDI). Despite its excellent efficacy, FMT is not yet a routine procedure in most centres. There is very little experience with FMT based on lyophilized capsules, and data from European institutions are lacking. This article describes our experience with FMT to treat recurrent CDI using lyophilized oral capsules. METHODS A prospectively recorded single-centre case series of patients with recurrent CDI who underwent FMT between January 2018 and May 2019 were analysed. The primary outcome was defined as resolution of CDI without recurrences over a two-month period. Overall resolution was defined as resolution of diarrhoea without recurrence of CDI within two months after a further cycle of FMT. The FMT process involved oral ingestion of four or five lyophilized capsules in a single dose. All stool donors were rigorously screened. FINDINGS FMT was performed in 32 patients. Primary cure was achieved in 81.3% of patients, and the overall cure rate was 87.5%. FMT via lyophilized capsules was well tolerated. No FMT procedure-related adverse events and no further complications were observed for lyophilized-capsule FMT. CONCLUSIONS This initial clinical experience suggests that FMT based on oral lyophilized preparations is a safe, well-tolerated, and highly effective treatment for recurrent CDI. Administration of oral lyophilized capsules seems feasible in hospital routine and will enable FMT to be more widely used.

Abstract
BACKGROUND Rifaximin has been proposed as an alternative treatment for specific cases of Clostridium difficile infection (CDI) and intestinal decontamination. Rifaximin-resistant C. difficile has occasionally been reported. Antibiotic susceptibility testing relies on anaerobic agar dilution (reference method), which is cumbersome and not routinely used. There is no commercial test for detection of resistance to rifaximin. OBJECTIVES To assess resistance to rifaximin by C. difficile and to evaluate the correlation between the results of the rifampicin E-test and susceptibility to rifaximin. METHODS We compared the in vitro susceptibility of clinical CDI isolates to rifaximin over a 6-month period using the agar dilution method with susceptibility to rifampicin using the E-test. All isolates were characterized using PCR-ribotyping. Clinical data were recorded prospectively. RESULTS We recovered 276 consecutive C. difficile isolates and found that 32.2% of episodes were caused by rifaximin-resistant strains. The MICs for rifaximin ranged from <0.0009-256 mg/L, with a geometric mean (GM) of 0.256 mg/L, an MIC50/90 of 0.015/>256 mg/L. Rifaximin and rifampicin MICs were comparable, and all strains classed as resistant by agar dilution were correctly classified as resistant by E-test. The most common ribotypes were 001 (37.2%), 078/126 (14.3%), and 014 (12.0%). Ribotype 001 exhibited the highest MICs for rifaximin. CONCLUSIONS Resistance to rifaximin was common; resistance rates were higher in ribotype 001 strains. Susceptibility to rifaximin determined by agar dilution correlated with susceptibility to rifampicin determined using the E-test, including rifaximin-resistant strains. Our results suggest that the rifampicin E-test is a valid method for the prediction of rifaximin-resistant C. difficile.
