Project description:PurposeTo assess the incidence, risk factors, and clinical outcomes associated with (Clostridioides difficile infection) CDI following urological surgery, which is the leading cause of nosocomial diarrhea and a growing public health burden.MethodsWe queried the National Surgical Quality Improvement Program (NSQIP) to identify patients undergoing urological surgery in 2015-2016. We evaluated the 30-day incidence and factors associated with postoperative CDI and 30-day hospital readmission and length of stay as secondary outcomes. Among the subset of patients undergoing radical cystectomy with urinary diversion (surgery with highest CDI incidence) we used multivariable logistic regression analysis to evaluate independent clinical and demographic factors associated with postoperative CDI.ResultsWe identified 98,463 patients during the study period. The overall 30-day incidence of CDI was 0.31%, but varied considerably across surgery type. The risk of CDI was greatest following radical cystectomy with urinary diversion (2.72%) compared to all other urologic procedures (0.19%) and was associated with increased risk of hospital readmission (p < 0.0001), re-operation (p < 0.0001), and longer mean length of stay (p < 0.0001) in this cohort. Among patients undergoing radical cystectomy with urinary diversion, multivariable logistic regression revealed that preoperative renal failure (OR: 5.30, 95% CI 1.13-24.9, p = 0.035) and blood loss requiring transfusion (OR: 1.67, 95% CI 1.15-2.44, p = 0.0075) were independently associated with CDI.ConclusionsIn a nationally representative cohort, the incidence of CDI was low but varied substantially across surgery types. CDI was most common following radical cystectomy and associated with potentially modifiable factors such as blood transfusion and significantly longer length of stay.

Project description:BackgroundPostinfection irritable bowel syndrome (PI-IBS) affects ~14% patients after acute bacterial enterocolitis.AimThe aim of this study was to conduct a systematic review and meta-analysis to find the prevalence of PI-IBS following Clostridioides difficile infection (CDI).MethodsWe systematically searched Medline, Embase, and Web of Science from inception through January 20, 2020 for cohort studies assessing PI-IBS following CDI. Primary outcome was pooled prevalence calculated using inverse variance heterogeneity model [MetaXL (v. 5.3)]. A priori subgroup analyses were done [by irritable bowel syndrome (IBS) diagnostic criteria-Rome vs. others, time of IBS diagnosis-<6 or >6 mo, exclusion or inclusion of pre-existing IBS and CDI treatment-antibiotic with fecal microbiota transplantation vs. antibiotic only]. Heterogeneity was considered substantial if I2>50%.ResultsFrom 2007 to 2019, 15 studies were included (10 prospective, 5 retrospective; 9 full-text, 6 abstracts). Data from 1218 patients were included in the quantitative analysis. Risk of bias was low in 7, medium in 4 and high in 4 studies. Pooled prevalence of PI-IBS was 21.1% (95% confidence interval, 8.2%-35.7%), I2=96%. Common PI-IBS subtypes were diarrhea-predominant in 46.3% (50) patients, and mixed in 33.3% (36) patients. Subgroup analyses by IBS diagnostic criteria, time of IBS diagnosis or CDI treatment did not significantly change the primary outcome (all P>0.05), nor decrease heterogeneity. Funnel plot analysis revealed publication bias.ConclusionsOver 20% of patients develop PI-IBS after CDI. Factors such as diagnostic criteria for IBS and CDI treatment did not affect prevalence, though small numbers limit the confidence in these conclusions. Larger, well conducted studies are needed to study PI-IBS in CDI.

Project description:ObjectivesTo investigate the relationship between Clostridium (Clostridioides) difficile strain characteristics and C. difficile infection (CDI) outcome.MethodsBetween October and December 2017, 16 hospitals collected epidemiological data according to the European Centre for Disease Prevention and Control (ECDC) surveillance protocol for CDI. C. difficile isolates were characterized by ribotyping, toxin genes detection and antibiotic susceptibility testing to metronidazole, vancomycin and moxifloxacin.ResultsThe overall mean CDI incidence density was 4.5 [95% CI 3.6-5.3] cases per 10,000 patient-days. From the 433 CDI cases, 330 (76.2%) were healthcare-associated, 52 (12.0%) cases were community-associated or of unknown origin and 51 (11.8%) CDI cases recurrent; a complicated course of CDI was reported in 65 cases (15.0%). Eighty-eight (20.3%) of patients died and 59 of them within 30 days after the CDI diagnosis. From the 379 C. difficile isolates, the most prevalent PCR ribotypes were 001 (n = 127, 33.5%) and 176 (n = 44, 11.6%). A total of 186 (49.1%) isolates showed a reduced susceptibility to moxifloxacin (> 4 mg/L) and 96.4% of them had Thr82Ile in the GyrA. Nineteen isolates revealed reduced susceptibility to metronidazole and two isolates to vancomycin (> 2 mg/L). A fatal outcome was associated with a reduced susceptibility to moxifloxacin, the advanced age of the patients and a complicated course of CDI (p<0.05). No association between ribotype, binary toxin and a reduced susceptibility to moxifloxacin and complicated course or recurrent CDI was found.ConclusionsA reduced susceptibility to moxifloxacin, in causative C. difficile strains was associated with fatal outcome of the patients, therefore it is an important marker in surveillance of CDI.

Project description:Clostridioides (Clostridium) difficile is the major cause of healthcare antibiotic-associated diarrhoea. However, extra-intestinal manifestations of Clostridioides (Clostridium) difficile infection (CDI) (including bacteremia and tissue infection) are extremely rare. We report a case of extraintestinal CDI after surgery. The isolate of C. difficile was not the PCR ribotype 027. However, this isolate produced toxins A and B. The patient underwent a follow-up examination 30 days after discharge, which showed complete recovery. This case report adds to existing knowledge of CDI.

Project description:Our systematic review and meta-analysis of 40 studies (n = 3,905,559) identified gastric acid suppressants, recent hospitalization, antibiotic exposure, and certain comorbidities as independent predictors of healthcare-associated Clostridioides difficile infection (HA-CDI) among adult inpatients. Targeted antibiotic stewardship and judicious use of gastric acid suppressants can reduce the incidence of HA-CDI.

Project description:BackgroundMicrobiota restoration is highly effective to treat recurrent Clostridioides difficile infection (CDI) in observational studies (cure rates >90%) but efficacy in controlled clinical trials appears to be lower.ObjectivesTo perform an updated meta-analysis to assess the efficacy of microbiota restoration for recurrent CDI in open-label registered prospective clinical trials compared to randomized controlled trials (RCTs).DesignA systematic review and meta-analysis was conducted.Data sources and methodsA systematic search of various databases was performed up to July 2022 to identify studies of interest. Clinical trials of microbiota restoration for recurrent CDI with clinical resolution with one dose were included. We calculated weighted pooled rates (WPRs) with 95% confidence intervals (CIs).ResultsIn all, 19 clinical trials with 1176 recurrent CDI patients were included. Of the patients treated with microbiota restoration, 897 experienced a clinical cure with a single microbiota restoration therapy (WPR, 78%; 95% CI, 71-85%). There was significant heterogeneity among studies with an I2 of 88%. Analysis of trials with a control arm (non-microbiota restoration) revealed CDI resolution in 373 of 523 patients (WPR, 72%; 95% CI, 60-82%) with microbiota restoration. Among the nine open-label clinical trials, CDI resolution was seen in 524 of 653 patients after initial microbiota restoration (WPR, 84%; 95% CI, 74-92%). Comparison of resolution rates between RCTs and open-label trials revealed a lower cure rate in RCTs compared to open-label trials (WPR, 73 versus 84%, p < 0.0001).ConclusionsMicrobiota restoration in a randomized controlled setting leads to lower resolution rates compared to open label and observational settings, likely due to stricter definitions and inclusion criteria. Resolution rates in open-label studies were similar to observational studies.

Project description:BackgroundClostridioides difficile infection (CDI) is an infectious nosocomial disease caused by Clostridioides difficile, an opportunistic pathogen that occurs in the intestine after extensive antibiotic regimens.ResultsNine C. difficile strains (CBA7201-CBA7209) were isolated from nine patients diagnosed with CDI at the national university hospital in Korea, and the whole genomes of these strains were sequenced to identify their genomic characteristics. Comparative genomic analysis was performed using 51 reference strains and the nine isolated herein. Phylogenetic analysis based on 16S rRNA gene sequences confirmed that all 60 C. difficile strains belong to the genus Clostridioides, while core-genome tree indicated that they were divided into five groups, which was consistent with the results of MLST clade analysis. All strains were confirmed to have a clindamycin antibiotic resistance gene, but the other antibiotic resistance genes differ depending on the MLST clade. Interestingly, the six strains belonging to the sequence type 17 among the nine C. difficile strains isolated here exhibited unique genomic characteristics for PaLoc and CdtLoc, the two toxin gene loci identified in this study, and harbored similar antibiotic resistance genes.ConclusionIn this study, we identified the specific genomic characteristics of Korean C. difficile strains, which could serve as basic information for CDI prevention and treatment in Korea.

Project description:BackgroundFaecal microbiota transplantation (FMT) is effective for recurrent Clostridioides difficile infection (CDI), but inconsistent effect rates and uncertain evidence levels have warranted caution. To clarify, we aimed to establish the evidence of FMT for recurrent CDI, updated across different delivery methods, treatment regimens, and in comparison with standard antibiotics.MethodsIn this updated systematic review and meta-analysis, we searched PubMed, Scopus, Embase, Web of Science, Clinical Key, and Svemed+ for FMT literature published in English until November 11, 2019. We included observational and clinical trials with or without antibiotic comparators and excluded studies with below 8 weeks follow-up and fewer than 15 patients. The primary outcome was clinical outcome by week 8. We comprehensively extracted patient and procedural data. In a random-effects meta-analysis, we estimated the clinical effect for repeat or single FMT, different delivery methods, and versus antibiotics. We rated the evidence according to the Cochrane and GRADE methods. The PROSPERO preregistration number is CRD42020158112.FindingsOf 1816 studies assessed, 45 studies were included. The overall clinical effect week 8 following repeat FMT (24 studies, 1855 patients) was 91% (95% CI: 89-94%, I 2=53%) and 84% (80-88%, I 2=86%) following single FMT (43 studies, 2937 patients). Delivery by lower gastrointestinal endoscopy was superior to all other delivery methods, and repeat FMT significantly increased the treatment effect week 8 (P<0·001). Compared with vancomycin, the number needed to treat (NNT) for repeat FMT was 1·5 (1·3-1·9, P<0·001) and 2.9 (1·5-37·1, P=0·03) for single FMT. Repeat FMT had high quality of evidence.InterpretationHigh-quality evidence supports FMT is effective for recurrent CDI, but its effect varies with the delivery method and the number of administrations. The superior NNT for FMT compared with antibiotics suggests that patients may benefit from advancing FMT to all instances of recurrent CDI.FundingInnovation Fund Denmark (j.no. 8056-00006B).
