Characterization of community-acquired Clostridioides difficile strains in Israel, 2020-2022. Front Microbiol 2023; 14:1323257. [PMID: 38169783 PMCID: PMC10758451 DOI: 10.3389/fmicb.2023.1323257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Accepted: 11/29/2023] [Indexed: 01/05/2024] Open
Abstract
Background The prevalence of community-acquired Clostridioides difficile infection (CA-CDI) has been rising, due to changes in antibiotics prescribing practices, emergence of hypervirulent strains and improved diagnostics. This study explored CA-CDI epidemiology by examining strain diversity and virulence factors of CA-CDI isolates collected across several geographical regions in Israel. Methods Stool samples of 126 CA-CDI patients were subjected to PCR and an immunoassay to identify toxin genes and proteins, respectively. Toxin loci PaLoc and PaCdt were detected by whole-genome sequencing (WGS). Biofilm production was assessed by crystal violet-based assay. Minimum inhibitory concentration was determined using the Etest technique or agar dilution. WGS and multi-locus sequence typing (MLST) were used to classify strains and investigate genetic diversity. Results Sequence types (ST) 2 (17, 13.5%), ST42 (13, 10.3%), ST104 (10, 8%) and ST11 (9, 7.1%) were the most common. All (117, 92.8%) but ST11 belonged to Clade 1. No associations were found between ST and gender, geographic area or antibiotic susceptibility. Although all strains harbored toxins genes, 34 (27%) produced toxin A only, and 54 (42.9%) strains produced toxin B only; 38 (30.2%) produced both toxins. Most isolates were biofilm-producers (118, 93.6%), primarily weak producers (83/118, 70.3%). ST was significantly associated with both biofilm and toxin production. Conclusion C. difficile isolates in Israel community exhibit high ST diversity, with no dominant strain. Other factors may influence the clinical outcomes of CDI such as toxin production, antibiotic resistance and biofilm production. Further studies are needed to better understand the dynamics and influence of these factors on CA-CDI.

Clostridioides difficile Infections among Pediatric Patients Hospitalized at an Oncology Department of a Tertiary Hospital in Poland. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1363. [PMID: 37629653 PMCID: PMC10456884 DOI: 10.3390/medicina59081363] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 07/16/2023] [Accepted: 07/20/2023] [Indexed: 08/27/2023]
Abstract
Background and Objectives: Gastrointestinal tract infections caused by Clostridioides difficile bacteria are diagnosed in pediatric patients with increasing frequency. Children treated at pediatric units are a group of patients at high risk of this infection; therefore, appropriate differential diagnostics and an individual approach to every case are of particular importance. The goal of the study was to assess the clinical parameters of patients with a confirmed CD infection and colonization. Materials and Methods: Every positive case was subjected to a retrospective analysis based on medical history and an infection notification note. Results: Positive results were obtained for 30 patients, among whom the results of 18 patients were considered to justify the diagnosis of an infection. In the remaining patients, treatment was not initiated in only three cases. Cases were detected where treatment was initiated despite the lack of sufficient clinical evidence. Conclusions: This study demonstrates that there are many factors that result in a high risk of the occurrence of CDI in oncology patients, such as antibiotic therapy, multiple hospitalizations, and myelosuppression.

Clinical prediction rule for identifying older patients with toxigenic clostridioides difficile at the time of hospital admission. BMC Geriatr 2023; 23:127. [PMID: 36879198 PMCID: PMC9990199 DOI: 10.1186/s12877-023-03808-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 02/08/2023] [Indexed: 03/08/2023] Open
Abstract
BACKGROUND This study aimed to develop and validate a clinical prediction rule to screen older patients at risk of being toxigenic Clostridioides difficile carriers at the time of hospital admission. METHODS This retrospective case-control study was performed at a university-affiliated hospital. Active surveillance using a real-time polymerase chain reaction (PCR) assay for the toxin genes of C. difficile was conducted among older patients (≥ 65 years) upon admission to the Division of Infectious Diseases of our institution. This rule was drawn from a derivative cohort between October 2019 and April 2021 using a multivariable logistic regression model. Clinical predictability was evaluated in the validation cohort between May 2021 and October 2021. RESULTS Of 628 PCR screenings for toxigenic C. difficile carriage, 101 (16.1%) yielded positive findings. To establish clinical prediction rules in the derivation cohort, the formula was derived using significant predictors for toxigenic C. difficile carriage at admission, such as septic shock, connective tissue diseases, anemia, recent use of antibiotics, and recent use of proton-pump inhibitors. In the validation cohort, the sensitivity, specificity, and positive and negative predictive values of the prediction rule, based on a cut-off value of ≥ 0.45, were 78.3%, 70.8%, 29.5%, and 95.4%, respectively. CONCLUSION This clinical prediction rule for identifying toxigenic C. difficile carriage at admission may facilitate the selective screening of high-risk groups. To implement it in a clinical setting, more patients from other medical institutions need to be prospectively examined.

Prevalence of and factors associated with inappropriate Clostridioides difficile testing in a teaching hospital in Korea. Antimicrob Resist Infect Control 2022; 11:70. [PMID: 35562785 PMCID: PMC9107266 DOI: 10.1186/s13756-022-01111-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Accepted: 04/29/2022] [Indexed: 11/15/2022] Open
Abstract
Background Given the increasing incidence of Clostridioides difficile infections in Korea, there has been an increase in inappropriate testing for C. difficile, which has rendered overdiagnosis of asymptomatic colonisers common. We aimed to investigate the appropriateness of C. difficile testing and the related factors. Methods We retrospectively reviewed the medical records of patients who were admitted to a 1300-bed tertiary-care teaching hospital in Korea and were tested for C. difficile infection from September 2019 to November 2019. We performed logistic regression analysis to investigate factors related to inappropriate testing. Further, a survey was conducted on physicians to assess the knowledge and ordering patterns of C. difficile testing. Results We included 715 tests from 520 patients in the analysis. Testing was classified as hospital-onset and community-onset and subclassified as appropriate and inappropriate following an algorithmic method. Among the 715 tests, 576 (80.6%) and 139 (19.6%) tests were classified as hospital-onset and community-onset, respectively. Among the hospital-onset tests, 297 (52%) were considered inappropriate. The risk of inappropriate testing increased when C. difficile tests were conducted in the emergency room (OR 24.96; 95% CI 3.12–199.98) but decreased in intensive care units (OR 0.36, 95% CI 0.19–0.67). The survey was conducted on 61 physicians. Internal medicine physicians had significantly higher scores than non-internal medicine physicians (7.1 vs. 5.7, p = 0.001). The most frequently ordered combination of tests was toxin + glutamate dehydrogenase (47.5%), which was consistent with the ordered tests. Conclusion Almost half of the C. difficile tests were performed inappropriately. The patient being located in the emergency room and intensive care unit increased and decreased the risk of inappropriate testing, respectively. In a questionnaire survey, we showed that internal medicine physicians were more knowledgeable about C. difficile testing than non-internal medicine physicians. There is a need to implement the diagnostic stewardship for C. difficile, especially through educational interventions for emergency room and non-internal medicine physicians.

Abstract
Background: The 2016 cumulative incidence of Clostridioides difficile infection (CDI) in Spain was reported by the European Center for Disease Control to be above the mean of other European countries. The aim of this multicenter prospective observational cohort study was to examine the risk factors that determine 90-day CDI recurrence in Catalonia, Spain. Methods: The study included 558 consecutive adults admitted to hospital who had a symptomatic, first positive CDI diagnosis. Sociodemographic, clinical and epidemiological variables were recorded. The primary outcome was 90-day CDI recurrence. Results: In this Catalan population, having received more than one course of antibiotics in the 30 days prior to CDI diagnosis (odds ratio: 2.459; 95% CI: 1.195–5.060; p = 0.015) and active chemotherapy (odds ratio: 4.859; 95% CI: 1.495–15.792; p = 0.009) are significant predictors of 90-day CDI recurrence. Conclusion: The identification of independent risk factors of 90-day CDI recurrence will enable the optimization of preventive measures in at-risk populations.

Risk Factors, Diagnosis, and Management of Clostridioides difficile Infection in Patients with Inflammatory Bowel Disease. Microorganisms 2022; 10:microorganisms10071315.

Abstract
Clostridioides difficile infection (CDI) and inflammatory bowel disease (IBD) are two pathologies that share a bidirectional causal nexus, as CDI is known to have an aggravating effect on IBD and IBD is a known risk factor for CDI. The colonic involvement in IBD not only renders the host more prone to an initial CDI development but also to further recurrences. Furthermore, IBD flares, which are predominantly set off by a CDI, not only create a need for therapy escalation but also prolong hospital stay. For these reasons, adequate and comprehensive management of CDI is of paramount importance in patients with IBD. Microbiological diagnosis, correct evaluation of clinical status, and consideration of different treatment options (from antibiotics and fecal microbiota transplantation to monoclonal antibodies) carry pivotal importance. Thus, the aim of this article is to review the risk factors, diagnosis, and management of CDI in patients with IBD.

Abstract
BACKGROUND The study's objective was to investigate the incidence and risk factors associated with Clostridioides difficile (previously known as Clostridium) infection (CDI) in children with inflammatory bowel disease (IBD) in the province of Manitoba. METHODS Our longitudinal population-based cohort was comprised of all children and young adults aged <17 years diagnosed with IBD in the Canadian province of Manitoba between 2011 and 2019. The diagnosis of CDI was confirmed based on the Triage C. difficile immunoassay and polymerase chain reaction assay to detect the presence of toxigenic C. difficile. The Fisher exact test was used to examine the relationship between categorical variables. A Cox regression model was used to estimate the risk of CDI development in IBD patients. RESULTS Among 261 children with IBD, 20 (7.7%) developed CDI with an incidence rate of 5.04 cases per 1000 person-years, and the median age at diagnosis (interquartile range) was 12.96 (9.33-15.81) years. The incidence rates of CDI among UC and CD patients were 4.16 cases per 1000 person-years and 5.88 cases per 1000 person-years, respectively (P = 0.46). Compared with children without CDI, those who had CDI were at increased risk of future exposure to systemic corticosteroids (adjusted hazard ratio [aHR], 4.38; 95% confidence interval [CI], 1.46-13.10) and anti-tumor necrosis factor (anti-TNF) biologics (aHR, 3.31; 95% CI, 1.11-9.90). The recurrence rate of CDI in our pediatric IBD population was 25%. CONCLUSIONS Our findings confirm that children with IBD are at high risk of developing CDI, which may predict future escalation of IBD therapy.

Abstract
Clostridioides difficile (C.difficile) is a Gram-positive, spore-forming, toxin-producing anaerobic bacillus, which is one of the most common causes of health-care-associated infection developed mainly by elderly patients. The objective of this study was to assess mortality among the patients of the Hospital for Infectious Diseases in Warsaw related to C.difficile infection. Analysis was conducted of 1638 records reporting the medical histories of patients hospitalized for the first time due to Clostridioides difficile infection (CDI) in the Hospital for Infectious Diseases in Warsaw from 2010 to 2017. The inclusion criteria were any (principal or secondary) discharge diagnosis code for CDI according to ICD-10 and being an adult (≥ 18 years). 108 out of 1638 (7%) of the patients died. The median age in this group was 83 years. The largest number of deaths (90%) occurred in the group of patients aged 65 years or older and 81–90 years old (53% of all the deaths). In the multivariate logistic regression model relevant only to the age groups, not to sepsis—age over 80 and over 90 were independent predictors of death, increasing the risk of death by 3.4 and 1.8 times, respectively. The result of the receiver operating curve (ROC) analysis determined the age of 77 years as the threshold value, indicating the increased risk of death (AUC 0.727, standard error 0.025, 95% CI 0.678–0.776, p < 0.0001). In addition, other quantitative variables, namely CRP, creatinine and leucocytes were studied and turned out to be independent death predictors as well. The diagnosis of sepsis increased the risk of death fourfold (OR = 4.042; 95% Cl 2.4–6.7; p < 0.001). Increased inflammatory parameters, namely CRP and white blood cell count, advanced age, particularly over the age of 80, as well as a diagnosis of sepsis are independent risk factors for death and could be used as predictive markers of poor outcome in CDI.

Abstract
Clostridium difficile (CD) diagnosis is very varied and under discussion. Different research groups disagree on the clinical significance of patients with negative direct toxin and positive polymerase chain reaction (PCR) or even more with direct toxin and glutamate dehydrogenase (GDH) both negatives, but CD detected by toxigenic culture (TC). The objective was to analyze the characteristics of patients with 3 different diagnostic criteria. We compared these 3 groups of patients: group 1: (GDH+/direct toxin+/PCR+), group 2: (GDH+/direct toxin-/PCR+) and group 3: (GDH-/direct toxin-/PCR not done/TC+). The proportion of patients with CD infection (CDI) (not colonization) for groups 1 to 3 was, respectively, 90.3%, 95.4%, and 59.1%. No differences between severity (40.8%, 38.5%, 27.3%), recurrence (20.3%, 24.1%, 7.6%), or related mortality (12.5%, 5.2%, 0%) were found within the 3 groups of patients. Laboratory clinical results should not be used as the only tool to differentiate CDI versus colonization or severity. We recommend that PCR or a second-look TC be performed on all patients.

Abstract
Background There is a reported association between proton pump inhibitor (PPI) exposure and increased risk of Clostridium difficile infection (CDI), but less is known about how this class of medications taken during treatment might influence mortality after CDI. Here we examine 180-day mortality rates in a cohort of CDI elders and its association with exposure to PPIs. We conducted a retrospective cohort study of elderly patients (> 65 years of age) diagnosed and treated for CDI in the years 2014–2016 (n = 874) in the Umass Memorial Health Care system, which represents both academic and community healthcare. Patient characteristics and medication use was extracted from the electronic medical record (EMR) and 6 month mortality data was obtained via the Center for Disease Control National Death Index. A Cox proportional hazards model was used to estimate hazard ratios associated with medication exposures and other relevant variables. Results Of the 874 elderly adults treated for CDI, 180-day all-cause mortality was 12.4%. Exposure to a PPI was associated with a 55% reduced risk of mortality (adjusted hazard ratio (aHR) 0.45; 95% confidence interval (CI) 0.28–0.72). In our Cox model, increasing age (aHR 1.45; 95% CI 1.14–1.84), those with severe CDI infections (aHR 1.87; 95% CI 1.22–2.88), and those with hospital acquired CDI (aHR 3.01; 95% CI 1.81–4.99) also had increased 180 day mortality risk. There were similar associations noted with both 90 day and 1-year mortality. Conclusion Use of PPIs during CDI treatment in elderly patients is associated with decreased 180-day mortality. Although use of PPIs has been associated with an increased risk of CDI, it appears to be protective against mortality when used during the treatment phase.

Abstract
BACKGROUND AND AIM Clostridium difficile infection [CDI] is a significant concern in inflammatory bowel disease [IBD]. Risk factors and consequences associated with CDI in inflammatory bowel disease [IBD] patients are important to characterize. The aim of this research was to perform a systematic review and meta-analysis on risk factors and outcomes associated with CDI in IBD patients. METHODS Multiple databases were searched for studies investigating risk factors, colectomy and mortality risk in IBD patients with and without CDI. This was stratified by short [<3 months] and long-term [>1 year] outcomes. Summary estimates were calculated using a random-effects model. Quality assessment used the Newcastle-Ottawa scale. RESULTS Twenty-two studies met inclusion criteria. Antibiotics use within 30 days of diagnosis was associated with CDIs (odds ratio [OR]: 1.85, 95% confidence interval [CI]:1.36, 2.52). Colonic involvement in Crohn's disease patients was associated with significantly higher CDI rates [OR: 2.76, 95% CI: 1.75, 4.35]. There was a significant association between biologic medication use and CDI [OR: 1.65, 95% CI: 1.18, 2.30], with minimal heterogeneity [I2 = 4.0%]. The long-term colectomy risk was significantly higher for IBD patients with CDI compared with that for IBD patients without CDI [OR: 2.22, 95% CI: 1.17, 4.18]. Significantly higher mortality was found for CDI in IBD patients both short-term [OR: 3.84, 95% CI: 2.62, 5.61] and long-term [OR: 3.65, 95% CI: 1.58, 8.44]. Substantial heterogeneity existed. Most studies were of moderate quality. CONCLUSION Colonic involvement, and biologic and antibiotic use appear to be risk factors associated with CDI among IBD patients. CDI is associated with increased short- and long-term mortality.
