Abstract
We investigated epidemiologic and molecular characteristics of healthcare-associated (HA) and community-associated (CA) Clostridioides difficile infection (CDI) among adult patients in Canadian Nosocomial Infection Surveillance Program hospitals during 2015–2019. The study encompassed 18,455 CDI cases, 13,735 (74.4%) HA and 4,720 (25.6%) CA. During 2015–2019, HA CDI rates decreased by 23.8%, whereas CA decreased by 18.8%. HA CDI was significantly associated with increased 30-day all-cause mortality as compared with CA CDI (p<0.01). Of 2,506 isolates analyzed, the most common ribotypes (RTs) were RT027, RT106, RT014, and RT020. RT027 was more often associated with CDI-attributable death than was non-RT027, regardless of acquisition type. Overall resistance C. difficile rates were similar for all drugs tested except moxifloxacin. Adult HA and CA CDI rates have declined, coinciding with changes in prevalence of RT027 and RT106. Infection prevention and control and continued national surveillance are integral to clarifying CDI epidemiology, investigation, and control.

Abstract
Clostridioides difficile is a leading cause of human antibiotic-associated diarrhoeal disease globally. Zoonotic reservoirs of infection are increasingly suspected to play a role in the emergence of this disease in the community and dogs are considered as one potential source. Here we use a canine case-control study at a referral veterinary hospital in Scotland to assess: i) the risk factors associated with carriage of C. difficile by dogs, ii) whether carriage of C. difficile is associated with clinical disease in dogs and iii) the similarity of strains isolated from dogs with local human clinical surveillance. The overall prevalence of C. difficile carriage in dogs was 18.7% (95% CI 14.8–23.2%, n = 61/327) of which 34% (n = 21/61) were toxigenic strains. We found risk factors related to prior antibiotic treatment were significantly associated with C. difficile carriage by dogs. However, the presence of toxigenic strains of C. difficile in a canine faecal sample was not associated with diarrhoeal disease in dogs. Active toxin was infrequently detected in canine faecal samples carrying toxigenic strains (2/11 samples). Both dogs in which active toxin was detected had no clinical evidence of gastrointestinal disease. Among the ten toxigenic ribotypes of C. difficile detected in dogs in this study, six of these (012, 014, 020, 026, 078, 106) were ribotypes commonly associated with human clinical disease in Scotland, while nontoxigenic isolates largely belonged to 010 and 039 ribotypes. Whilst C. difficile does not appear commonly associated with diarrhoeal disease in dogs, antibiotic treatment increases carriage of this bacteria including toxigenic strains commonly found in human clinical disease.

Abstract
Clostridioides difficile is an increasingly common pathogen both within and outside the hospital and is responsible for a large clinical spectrum from asymptomatic carriage to complicated infection associated with a high mortality. While diagnostic methods have considerably progressed over the years, the optimal diagnostic algorithm is still debated and there is no single diagnostic test that can be used as a standalone test. More importantly, the heterogeneity in diagnostic practices between centers along with the lack of robust surveillance systems in all countries and an important degree of underdiagnosis due to lack of clinical suspicion in the community, hinder a more accurate evaluation of the burden of disease. Our improved understanding of the physiopathology of CDI has allowed some significant progress in the treatment of CDI, including a broader use of fidaxomicine, the use of fecal microbiota transplantation for multiples recurrences and newer approaches including antibodies, vaccines and new molecules, already developed or in the pipeline. However, the management of CDI recurrences and severe infections remain challenging and the main question remains: how to best target these often expensive treatments to the right population. In this review we discuss current diagnostic approaches, treatment and potential prevention strategies, with a special focus on recent advances in the field as well as areas of uncertainty and unmet needs and how to address them.

Abstract
Objective: This single-center, retrospective, observational cohort study evaluates the
appropriateness of the BioFire® FilmArray® Gastrointestinal (GI) multiplex
PCR panel testing at a community-teaching hospital. Methods: All adult, hospitalized patients at Prisma Health Richland Hospital with a
documented GI multiplex PCR panel from 1 April 2015 through 28 February 2018
were included in the analysis. Inappropriate use of the GI panel was defined
as a test obtained without documented diarrhea, greater than 2 days of
hospitalization, redundant use with other diagnostic tests (e.g.
Clostridioides difficile PCR), or laxative use in the
preceding 48 h. Antibiotic use and host variables were compared between
groups with positive and negative results. Results: During the study period, 442 GI panels were obtained, among which 268 (61%)
were deemed inappropriate. Primary reasons for inappropriate testing were
lack of documented diarrhea (n = 92), greater than 2 days
of hospitalization (n = 116), having a duplicate C.
difficile PCR test ordered (n = 118), or
laxative use in the 48 h before testing (n = 36). A total
of 141 (32%) GI panels were positive. The most frequently identified
pathogens were C. difficile (51.1%,
n = 72), Enteropathogenic Escherichia coli
(17.7%, n = 25), and Norovirus GI/GII (12.1%,
n = 17). Patients with negative GI panel results were
initiated on antibiotics significantly less frequently than those with
positive GI panels (62.5% versus 80.2%,
p < 0.00001). Conclusion: Stewardship opportunities exist to optimize the diagnostic application of the
GI multiplex PCR panel.

Clostridioides (Clostridium) difficile infection in Japanese hospitals 2008-2017: A real-world nationwide analysis of treatment pattern, incidence and testing density. J Infect Chemother 2020; 26:438-443. [PMID: 32081648 DOI: 10.1016/j.jiac.2019.11.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Revised: 10/30/2019] [Accepted: 11/09/2019] [Indexed: 01/04/2023]
Abstract
OBJECTIVE To characterize treatment pattern, incidence and diagnosis of hospital-onset Clostridioides difficile infection (CDI) in Japan, cases were studied over a 9-year period using a large, administrative database. METHODS This was a retrospective, cross-sectional analysis of inpatients at 320 Japanese Diagnosis-Procedure Combination (DPC) hospitals. Hospitalizations between April 2008 and March 2017 were extracted for patients aged ≥18 years. CDI was defined as CDI treatment plus CDI diagnosis or positive enzyme immunoassay (EIA) result. Endpoints included treatment (type, route, daily dose, duration), time to CDI onset from admission, and time to recurrence (rCDI) from the end of treatment. Chronological changes were reported for treatment pattern, CDI incidence and EIA testing. RESULTS The analysis included 11,823 CDI hospitalizations, 1359 with rCDI. Overall, oral metronidazole (MNZ), oral vancomycin (VCM), and intravenous MNZ were used in 50.2%, 42.1% and 1.2% of CDI hospitalizations, respectively. From 2009 to 2017, CDI hospitalizations treated with MNZ more than doubled and VCM more than halved. Median (Q1-Q3) time to CDI and rCDI onset was 25 (11-52) days and 10 (6-17.5) days, respectively. Median treatment duration ranged from 8 to 10 days and median dose was 1 g/day for both MNZ and VCM. CDI incidence remained steady from 2010 until 2017 (0.99/10,000 patient-days) and EIA testing density doubled from 2008 to 2017 (24.46/10,000 patient-days). CONCLUSION Oral MNZ has become the primary CDI treatment in Japanese DPC hospitals. The treatment duration and dose were aligned to the package insert. CDI diagnostic testing density increased over time, CDI incidence did not. CLINICAL TRIAL REGISTRATION NUMBER N/A.

Abstract
The burden of community-associated Clostridium difficile infection (CA-CDI) has increased. We aimed to describe the epidemiology of CA-CDI to inform future interventions. We used population-based linked surveillance data from 2012 to 2016 to describe socio-demographic factors, ribotype and mortality for all CA (n = 1303) and hospital-associated (HA, n = 1356) CDI. For 483 community-onset (CO) CA-CDI and 287 COHA-CDI cases, a questionnaire on risk factors was completed and we conducted a case-case study using logistic regression models for univariate and multivariable analysis. CA-CDI cases had lower odds of being male (adjusted odds ratio (AOR) 0.71, 95% confidence interval (CI) 0.58-0.87; P < 0.001), and higher odds of living in rural rather than urban settlement (AOR 1.5, 95% CI 1.1-2.1; P = 0.05) compared with HA-CDI cases. The distribution of ribotypes was similar in both groups with RT078 being most prevalent. CDI-specific death was lower in CA-CDI than HA-CDI (7% vs. 11%, P < 0.001). COCA-CDI had lower odds of having had an outpatient appointment in the previous 4 weeks compared with COHA-CDI (AOR 0.61; 95% CI 0.41-0.9, P = 0.01) and lower odds of being in a care home or hospice when compared with their own home, than COHA-CDI (AOR 0.66; 95% CI 0.45-0.98 and AOR 0.35; 95% CI 0.13-0.92, P = 0.02). Exposure to gastric acid suppressants (50% in COCA-CDI and 55% in COHA-CDI) and antimicrobial therapy (18% in COCA-CDI and 20% in COHA-CDI) prior to CDI was similar. Our analysis of community-onset cases suggests that other risk factors for COHA-CDI may be equally important for COCA-CDI. Opportunities to safely reduce antibiotic and gastric acid suppressants use should be investigated in all healthcare settings.

Abstract
Clostridioides (formerly: Clostridium) difficile infection (CDI) is a major cause of diarrhoea for inpatients as well as outpatients. Usually, CDI is healthcare-associated but the number of community-acquired infections is increasing. CDI is generally associated with changes in the normal intestinal microbiota caused by administration of antibiotics. Elderly and immunocompromised patients are at greater risk for CDI and CDI recurrence. Recently, the treatment options of CDI have undergone major changes: current recommendations speak against using metronidazole for primary CDI, fidaxomicin and bezlotoxumab have been added to the treatment armamentarium and microbial replacement therapies have emerged. Several other therapies are undergoing clinical trials. In this article, we review current treatment guidelines, present the most recent data on the options to treat CDI and glance towards future developments.KEY MESSAGESThe cornerstones for the treatment of CDI are vancomycin and fidaxomicin. Metronidazole should be used only in mild-to-moderate disease in younger patients who have no or only few risk factors for recurrence.In recurrent CDI, bezlotoxumab infusion (a monoclonal antibody against C. difficile toxin B) may be considered as an adjunctive therapeutic strategy in addition to the standard care provided to patients with several risk factors for recurrence.Faecal microbiota transplantation (FMT) should be offered to patients with frequently recurring CDI.

Abstract
BACKGROUND Previous decades have witnessed a change in the epidemiology of Clostridium difficile infections. This study aimed to determine temporal trends in the incidence of C difficile infection across geographic regions. METHODS An initial search of the relevant literature was conducted from date inception to October 2018 without language restriction. We estimated the pooled incidences using logit transformation, weighted by inverse variance. The Joinpoint Regression Analysis Program was used to explore its temporal trend. RESULTS Globally, the estimated incidence of C difficile infection increased from 6.60 per 10,000 patient-days in 1997 to 13.8 per 10,000 patient-days in 2004. Thereafter, a significant downward trend was observed, at -8.75% annually until 2015. From 2005 to 2015, the incidences in most European countries decreased at a rate between 1.97% and 4.11% per annum, except in France, where an increasing incidence was observed (β = 0.16; P < .001). The incidences have stabilized in North America over the same period; however, in Asia, the incidence increased significantly from 2006 to 2014 (annualized percentage change = 14.4%; P < .001). The increase was greatest in Western Asian countries, including Turkey and Israel (β > 0.10; P < .004). CONCLUSIONS This study revealed rapid changes in the incidence of C difficile infection. This meta-analysis should inform the allocation of resources for controlling C difficile infection and future surveillance efforts in countries where epidemiologic information on C difficile infection remains sparse.

Abstract
Clostridioides difficile (formerly Clostridium) is a major cause of healthcare associated diarrhea, and is increasingly present in the community. Historically, C difficile infection was considered easy to diagnose and treat. Over the past two decades, however, diagnostic techniques have changed in line with a greater understanding of the physiopathology of C difficile infection and the use of new therapeutic molecules. The evolution of diagnosis showed there was an important under- and misdiagnosis of C difficile infection, emphasizing the importance of algorithms recommended by European and North American infectious diseases societies to obtain a reliable diagnosis. Previously, metronidazole was considered the reference drug to treat C difficile infection, but more recently vancomycin and other newer drugs are shown to have higher cure rates. Recurrence of infection represents a key parameter in the evaluation of new drugs, and the challenge is to target the right population with the adapted therapeutic molecule. In multiple recurrences, fecal microbiota transplantation is recommended. New approaches, including antibodies, vaccines, and new molecules are already available or in the pipeline, but more data are needed to support the inclusion of these in practice guidelines. This review aims to provide a baseline for clinicians to understand and stratify their choice in the diagnosis and treatment of C difficile infection based on the most recent data available.

Abstract
OBJECTIVE To determine the attributable cost and length of stay of hospital-acquired Clostridioides difficile infection (HA-CDI) from the healthcare payer perspective using linked clinical, administrative, and microcosting data. DESIGN A retrospective, population-based, propensity-score-matched cohort study. SETTING Acute-care facilities in Alberta, Canada. PATIENTS Admitted adult (≥18 years) patients with incident HA-CDI and without CDI between April 1, 2012, and March 31, 2016. METHODS Incident cases of HA-CDI were identified using a clinical surveillance definition. Cases were matched to noncases of CDI (those without a positive C. difficile test or without clinical CDI) on propensity score and exposure time. The outcomes were attributable costs and length of stay of the hospitalization where the CDI was identified. Costs were expressed in 2018 Canadian dollars. RESULTS Of the 2,916 HA-CDI cases at facilities with microcosting data available, 98.4% were matched to 13,024 noncases of CDI. The total adjusted cost among HA-CDI cases was 27% greater than noncases of CDI (ratio, 1.27; 95% confidence interval [CI], 1.21-1.33). The mean attributable cost was $18,386 (CAD 2018; USD $14,190; 95% CI, $14,312-$22,460; USD $11,046-$17,334). The adjusted length of stay among HA-CDI cases was 13% greater than for noncases of CDI (ratio, 1.13; 95% CI, 1.07-1.19), which corresponds to an extra 5.6 days (95% CI, 3.10-8.06) in length of hospital stay per HA-CDI case. CONCLUSIONS In this population-based, propensity score matched analysis using microcosting data, HA-CDI was associated with substantial attributable cost.

Abstract
Clostridium difficile associated disease is fundamentally associated with dysbiosis of the gut microbiome as a consequence of antibiotic use. This is because this sporulating, obligate anaerobe germinates and proliferates rapidly in the dysbiotic gut, which is an indirect consequence of their use. During its growth, C. difficile produces two toxins, toxin A (TcdA) and toxin B (TcdB), which are responsible for the majority of clinical symptoms associated with the disease. Three parenterally delivered vaccines, based on detoxified or recombinant forms of these toxins, have undergone or are undergoing clinical trials. Each offers the opportunity to generate high titres of toxin neutralising antibodies. Whilst these data suggest these vaccines may reduce primary symptomatic disease, they do not in their current form reduce the capacity of the organism to persist and shed from the vaccinated host. The current progress of vaccine development is considered with advantages and limitations of each highlighted. In addition, several alternative approaches are described that seek to limit C. difficile germination, colonisation and persistence. It may yet prove that the most effective treatments to limit infection, disease and spread of the organism will require a combination of therapeutic approaches. The potential use and efficacy of these vaccines in low and middle income countries will be depend on the development of a cost effective vaccine and greater understanding of the distribution and extent of disease in these countries.

Suárez-Bode L, Barrón R, Pérez JL, Mena A. Increasing prevalence of the epidemic ribotype 106 in healthcare facility-associated and community-associated Clostridioides difficile infection. Anaerobe 2018; 55:124-129. [PMID: 30550807 DOI: 10.1016/j.anaerobe.2018.12.002] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2018] [Revised: 12/08/2018] [Accepted: 12/10/2018] [Indexed: 02/08/2023]
Abstract
Clostridioides difficile is the leading cause of nosocomial diarrhea and antibiotics associated diarrhea, but it is also an increasingly common cause of community diarrhea. In recent years we have observed a progressive increase in the incidence of C. difficile infection (CDI) both at the hospital and community setting that could be explained by the dynamic epidemiology of C. difficile. The present study analyzes changes in the epidemiology of CDI for two years comparing healthcare facility-associated (HCFA) and community-associated (CA) CDI epidemiology, observed in a single laboratory setting. All new episodes of CDI diagnosed during the years 2015-2016 were included in the study and classified as HFCA-, CA- or indeterminate CDI. Isolates were characterized by ribotyping and antimicrobial susceptibility was also determined. A total of 272 primary episodes of different patients were included in the study and classified 55.5% as CA-, 32% as HO-HCFA, 6.25% as CO-HCFA and 6.25% as indeterminate CDI. Overall, ribotype 106 was the most prevalent and also, many patients who suffered recurrent episodes were associated with this ribotype (29%). In fact, ribotype 106 showed a significantly higher recurrence rate than other ribotypes (26% vs 11%, p = 0.03). Moreover, 46% of the moxifloxacin resistant isolates were ribotype 106. No significant differences of antimicrobial resistance were observed between HCFA- and CA-CDI isolates, although fluoroquinolone resistance rates were slightly higher in HCFA-CDI isolates (25% vs 18.5%), and fluoroquinolone resistant ribotypes 106 and 126 were more frequently associated to CA-CDI and ribotype 078 to HCFA-CDI. The increasing incidence of CDI in our health care area is partially explained by the growing prevalence of the epidemic ribotype 106, both in HFCA- and CA-CDI, probably favored by the higher resistance and recurrence rate associated to ribotype 106 isolates.

Abstract
BACKGROUND In 2011, the Australasian Society for Infectious Diseases (ASID) and the Australian Infection Control Association (AICA), now known as the Australasian College of Infection Prevention and Control (ACIPC), produced a position statement on infection control requirements for preventing and controlling Clostridium difficile infection (CDI) in healthcare settings. METHODS The statement updated in 2017 to reflect new literature available .The authors reviewed the 2011 position statement and critically appraised new literature published between 2011 and 2017 and relevant current infection control guidelines to identify where new evidence had become available or best practice had changed. RESULTS The position statement was updated incorporating the new findings. A draft version of the updated position statement was circulated for consultation to members of ASID and ACIPC. The authors responded to all comments received and updated the position statement. CONCLUSIONS This updated position statement emphasizes the importance of health service organizations having evidence-based infection prevention and control programs and comprehensive antimicrobial stewardship programs, to ensure the risk of C. difficile acquisition, transmission and infection is minimised.

Abstract
Clostridium difficile is a major cause of hospital-associated diarrhoea, and in severe cases leads to pseudomembranous colitis and toxic megacolon. The frequency of C. difficile infection (CDI) has increased in recent decades, with 453 000 cases identified in 2011 in the USA. This is related to antibiotic-selection pressure, disruption of normal host intestinal microbiota and emergence of antibiotic-resistant C. difficile strains. The burden of community-acquired CDI has been increasingly appreciated, with disease identified in patients previously considered low-risk, such as young women or patients with no prior antibiotic exposure. C. difficile has been identified in livestock animals, meat products, seafood and salads. It has been postulated that the pool of C. difficile in the agricultural industry may contribute to human CDI. There is widespread environmental dispersal of C. difficile spores. Domestic households, turf lawns and public spaces are extensively contaminated, providing a potential reservoir for community-acquired CDI. In Australia, this is particularly associated with porcine-derived C. difficile UK PCR ribotype 014/020. In this article, the epidemiological differences between hospital- and community-acquired CDI are discussed, including some emerging evidence for community-acquired CDI being a possible zoonosis.

Abstract
Cross-sectional studies suggest an increasing trend in incidence and relatively low recurrence rates of Clostridium difficile infections in Asia than in Europe and North America. The temporal trend of C. difficile infection in Asia is not completely understood. We conducted a territory-wide population-based observational study to investigate the burden and clinical outcomes in Hong Kong, China, over a 9-year period. A total of 15,753 cases were identified, including 14,402 (91.4%) healthcare-associated cases and 817 (5.1%) community-associated cases. After adjustment for diagnostic test, we found that incidence increased from 15.41 cases/100,000 persons in 2006 to 36.31 cases/100,000 persons in 2014, an annual increase of 26%. This increase was associated with elderly patients, for whom incidence increased 3-fold over the period. Recurrence at 60 days increased from 5.7% in 2006 to 9.1% in 2014 (p<0.001). Our data suggest the need for further surveillance, especially in Asia, which contains ≈60% of the world’s population.

Abstract
We studied healthcare-associated and community-associated Clostridium difficile infection (CDI) in Jersey, Channel Islands (2008–2012). The Island’s stable population has reliable denominator data, a clearly defined at-risk population, and healthcare contact that is easily followed. The vast majority of CDI cases had had recent healthcare contact, and true community-associated disease is extremely rare.Infect Control Hosp Epidemiol 2018;39:603–607

Abstract
OBJECTIVE To describe the impact and epidemiology of Clostridium difficile infection (CDI) in low- and middle-human development index (LMHDI) countries. METHOD Prospectively registered, systematic literature review of existing literature in the PubMed, Ovid and Web of Science databases describing the epidemiology and management of C. difficile in LMHDI countries. Risk factors were compared between studies when available. RESULTS Of the 218 abstracts identified after applying search criteria, 25 studies were reviewed in detail. The weighted pooled infection rate among symptomatic non-immunosuppressed inpatients was 15.8% (95% CI 12.1-19.5%) and was 10.1% (95% CI 3.0-17.2%) among symptomatic outpatients. Subgroup analysis of immunosuppressed patient populations revealed pooled infection rates similar to non-immunosuppressed patient populations. Risk factor analysis was infrequently performed. CONCLUSIONS While the percentages of patients with CDI in LMHDI countries among the reviewed studies are lower than expected, there remains a paucity of epidemiologic data evaluating burden of C. difficile infection in these settings.
