[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.

Carvalho FAC, Silva ROS, Santos BMRTD, Diniz AN, Vilela EG. CLINICAL OUTCOME AND SEVERITY OF CLOSTRIDIOIDES (CLOSTRIDIUM) DIFFICILE INFECTION AT A TERTIARY REFERRAL HOSPITAL IN BRAZIL. ARQUIVOS DE GASTROENTEROLOGIA 2023; 60:330-338. [PMID: 37792762 DOI: 10.1590/s0004-2803.230302023-36] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 06/21/2023] [Indexed: 10/06/2023]
Abstract
•The outcomes of CDI were evaluated in 65 patients with CDI in a Brazilian tertiary hospital. •Lack of clinical improvement after treatment and the severity score (ATLAS) increased the risk of death. •The use of multiple antimicrobial agents was associated with longer hospital stays. •Patients with high Charlson comorbidity index (>7) were more likely to recur. Background - Clostridioides difficile infection (CDI) is a potentially severe disease that can present with refractoriness, recurrence, and evolution to death. In Brazil, the epidemiology of CDI seems to differ from that of the United States and most European countries, with only one ribotype (RT) 027-related case and a high prevalence of RT106. Objective - The aim of this study was to evaluate the outcomes of CDI and its possible association with ribotypes at a university hospital in Brazil. Methods - A total of 65 patients with CDI were included and stool samples were submitted to A/B toxin detection and toxigenic culture, and toxigenic isolates (n=44) were also PCR ribotyped. Results - Patients' median age was 59 (20-87) years and there were 16 (24.6%) deaths. The median Charlson comorbidity index (CCI) was 4 (0-15) and 16.9% of the patients had CCI ≥8. The ATLAS score and non-improvement of diarrhea were related to higher mortality. A longer length of hospitalization was related to the enteral nutrition and use of multiple antibiotics. The period between CDI diagnosis and hospital discharge was longer in those who received new antibiotics after diagnosis, multiple antibiotics, and required intensive care treatment. Recurrence was associated with CCI >7. Twenty ribotypes were identified and RT106 was the most frequently detected strain (43.2%). No relationship was observed between the ribotypes and outcomes. CDI was present in patients with more comorbidities. Conclusion - Risk factors for higher mortality, longer hospital stay and recurrence were identified. A diversity of ribotypes was observed and C. difficile strains were not related to the outcomes.

Abstract
Background Inflammatory bowel disease (IBD) patients are at increased risk of Clostridium difficile infection (CDI), causing significant morbidity and mortality. This study examined CDI's prevalence, predisposing factors, and clinical outcomes in Saudi hospitalized IBD patients. Methods : A retrospective case-control study was conducted at a tertiary medical city in Riyadh, Saudi Arabia. All Saudi adult patients with IBD, admitted over the preceding four years were identified from the hospital's database. Eligible patients were divided into those with CDI and those without CDI. Binary logistic regression was used to determine the predisposing factors for CDI among admitted IBD patients. Results During the study period, 95 patients were admitted with IBD. Crohn's disease (CD) was the predominant type (71.6%), whereas 28.4% of the patients were with ulcerative colitis (UC). Only 16 (16.8%) patients had positive CDI. CDI-positive patients tend to have hypertension and previous use of steroids. Patients with UC tend to have a higher risk of CDI than those with CD. Most patients recovered from the CDI (81.3%) with a median time to CDI clearance of 14 days. Three patients (18.8%) had recurrent CDI; among them, one died. Conclusion The prevalence of CDI in Saudi IBD patients is similar to that reported elsewhere. UC, steroid treatment, and hypertension are risk factors for CDI in IBD patients. Recurrence of CDI in IBD patients is common and associated with a poor prognosis.

Abstract
BACKGROUND There are uncertainties regarding associations of prior proton pump inhibitor (PPI) use with susceptibility for COVID-19 and risks associated with SARS-CoV-2 infection. We aimed to evaluate the associations of prior PPI use with outcomes in hospitalized patients with COVID-19. RESEARCH DESIGN AND METHODS We have retrospectively evaluated a total of 5959 consecutively hospitalized patients with COVID-19 from a tertiary-level institution in the period 3/2020-6/2021. Associations of prior PPI use with outcomes of in-hospital mortality, mechanical ventilation, intensive care unit stay, venous thromboembolism, arterial thrombosis, major bleeding, bacteremia, and Clostridioides difficile infection (C. diff.) were evaluated in entire and case-matched cohorts. RESULTS Among 5959 evaluated patients, there were 1967 (33%) PPI users. In an entire cohort, prior PPI use was associated with higher in-hospital mortality and higher occurrence of C. diff. Association of prior PPI use with mortality diminished, whereas association with C. diff. persisted after multivariable adjustments. In a matched cohort, prior PPI use was associated only with higher risk of C. diff. but not other outcomes in line with multivariable analysis. CONCLUSIONS Although prior PPI use might not have a significant impact on clinical course and mortality of SARS-CoV-2 infection, it may predispose patients to the development of complications like higher occurrence of C. diff. and thus substantially impact the course of treatment.

Abstract
PURPOSE OF REVIEW The chronic inflammatory bowel diseases (IBD), Crohn's disease, and ulcerative colitis, are associated with an increased risk of symptomatic Clostridium difficile infection (CDI). CDI may also masquerade as an IBD flare and complicate IBD management. This review provides a comprehensive overview of the epidemiology, diagnosis, and treatment of CDI in IBD patients. RECENT FINDINGS CDI remains common in IBD with complications including flares in disease activity, recurrent CDI episodes, and prolonged hospital stays. Newer IBD therapeutics including vedolizumab, ustekinumab, and tofacitinib are less likely to cause severe CDI. A high index of suspicion, rapid testing via a two-step method, and prompt treatment with vancomycin or fidaxomicin are paramount to managing CDI in IBD patients. Strategies to prevent recurrent CDI (rCDI) include the monoclonal antibody bezlotoxumab as well as fecal microbiota transplantation (FMT). FMT has a robust profile of safety and effectiveness in preventing rCDI in adults and children. SUMMARY Clinicians must remain vigilant in the prompt diagnosis and treatment of CDI in IBD patients. Corticosteroids, unnecessary antibiotics, and ongoing colonic inflammatory disease are modifiable risk factors. Improved infection control measures, newer IBD medications, and using effective CDI treatments will facilitate a reduced burden of severe CDI and complications for IBD patients.

Abstract
OBJECTIVE We evaluated the impact of test-order frequency per diarrheal episodes on Clostridioides difficile infection (CDI) incidence estimates in a sample of hospitals at 2 CDC Emerging Infections Program (EIP) sites. DESIGN Observational survey. SETTING Inpatients at 5 acute-care hospitals in Rochester, New York, and Atlanta, Georgia, during two 10-workday periods in 2020 and 2021. OUTCOMES We calculated diarrhea incidence, testing frequency, and CDI positivity (defined as any positive NAAT test) across strata. Predictors of CDI testing and positivity were assessed using modified Poisson regression. Population estimates of incidence using modified Emerging Infections Program methodology were compared between sites using the Mantel-Hanzel summary rate ratio. RESULTS Surveillance of 38,365 patient days identified 860 diarrhea cases from 107 patient-care units mapped to 26 unique NHSN defined location types. Incidence of diarrhea was 22.4 of 1,000 patient days (medians, 25.8 for Rochester and 16.2 for Atlanta; P < .01). Similar proportions of diarrhea cases were hospital onset (66%) at both sites. Overall, 35% of patients with diarrhea were tested for CDI, but this differed by site: 21% in Rochester and 49% in Atlanta (P < .01). Regression models identified location type (ie, oncology or critical care) and laxative use predictive of CDI test ordering. Adjusting for these factors, CDI testing was 49% less likely in Rochester than Atlanta (adjusted rate ratio, 0.51; 95% confidence interval [CI], 0.40-0.63). Population estimates in Rochester had a 38% lower incidence of CDI than Atlanta (summary rate ratio, 0.62; 95% CI, 0.54-0.71). CONCLUSION Accounting for patient-specific factors that influence CDI test ordering, differences in testing practices between sites remain and likely contribute to regional differences in surveillance estimates.

Abstract
WHAT IS ALREADY KNOWN •The rate and severity of Clostridioides difficile infection (CDI) has increased throughout North America, the United Kingdom, and Europe. •Scattered evidence about the association of CDI with antidepressant medications use exists in the literature so far. What are the new findings: •The risk of Clostridioides difficile infection is higher in patients who are on mirtazapine, nortriptyline, or trazodone. •The prevalence rate of Clostridioides difficile infection in patients who were using antidepressant medications and the ones who did not, increased with age. Background - During the past decade, Clostridioides difficile infection (CDI) has become the most common cause of antibiotic-associated diarrhea. Several risk factors have been implicated. Scattered evidence about the association of CDI with antidepressant medications use exists in the literature so far. Therefore, we aim to investigate whether the risk of developing CDI is increased in hospitalized patients using antidepressant medications.Methods - Patients who were hospitalized were included in our cohort. We excluded individuals aged less than 18 years. A multivariate regression analysis was performed to calculate the risk of CDI accounting for potential confounders. Results - The risk of CDI in hospitalized patients was increased in individuals diagnosed with inflammatory bowel disease (OR: 4.44; 95%CI: 4.35-4.52), and in patients using clindamycin (OR: 1.55; 95%CI: 1.53-1.57), beta-lactam antibiotics (OR: 1.62; 95%CI: 1.60-1.64), PPI (OR: 3.27; 95%CI: 3.23-3.30), trazodone (OR: 1.31; 95%CI: 1.29-1.33), nortriptyline (OR: 1.25; 95%CI: 1.21-1.28), and mirtazapine (OR: 2.50; 95%CI: 2.46-2.54). After controlling for covariates, the risk of CDI was not increased in patients who were taking fluoxetine (OR: 0.94; 95%CI: 0.92-0.96). Conclusion - In contrary to fluoxetine; mirtazapine, nortriptyline, and trazodone were associated with increased risk of CDI in hospitalized patients.

Abstract
OBJECTIVE Clostridioides difficile infection (CDI) is among the most common cause of healthcare-associated infections. Persons requiring maintenance hemodialysis (MHD) are at increased risk of CDI and associated mortality compared to persons not requiring MHD. Given the clinical impact of CDI among persons requiring MHD, we aimed to quantify the burden of CDI and trends over time in this patient population. STUDY DESIGN A systematic review and meta-analysis of studies reporting rates of CDI among persons requiring MHD in MEDLINE, Embase, Web of Science Core Collection, CINAHL, and Cochrane Central Register of Controlled Trials were performed. Searches were conducted on May 17, 2021, and March 4, 2022. RESULTS In total, 2,408 titles and abstracts were identified; 240 underwent full text review. Among them, 15 studies provided data on rates of CDI among persons requiring MHD, and 8 of these also provided rates among persons not requiring MHD. The pooled prevalence of CDI among persons requiring MHD was 19.14%, compared to 5.16% among persons not requiring MHD (odds ratio [OR], 4.35; 95% confidence interval [CI], 2.07-9.16; P = .47). The linear increase in CDI over time was significant, increasing an average of 31.97% annually between 1993 and 2017 (OR, 1.32; 95% CI, 1.1-1.58; P < .01). The linear annual increase was similar among persons requiring and not requiring MHD (OR, 1.28; 95% CI, 1.13-1.45; P = .11). CONCLUSIONS Persons requiring MHD have a 4-fold higher risk of CDI compared to persons not requiring MHD, and rates of CDI are increasing over time in both groups.

Abstract
INTRODUCTION Clostridioides difficile infection (CDI) is a major cause for antibiotic-associated diarrhea. Specific factors put the pediatrics at risk. International guidelines lists specific recommendations for the diagnosis and treatment of pediatric CDI. The practice of diagnosing and treating pediatric CDI in Saudi Arabia is slightly different from the recommendations of the guidelines. AREAS COVERED This review summarizes pediatric CDI in Saudi Arabia in terms of epidemiology, current diagnostics, and how the practice compares to recommendations of the guidelines, and available treatment options. EXPERT OPINION Although pediatric CDI epidemiology in Saudi Arabia doesn't impose a burden on the healthcare system, it should be noted that not all hospitals follow CDI diagnostic recommendations of international guidelines, which may result in cases underreporting. However, due to the presumed low CDI prevalence, the traditional regimen of oral metronidazole for non-severe CDI remains effective, whereas vancomycin is used for severe cases. While fidaxomicin is approved for pediatrics, its high acquisition cost and low CDI rates make it challenging for hospitals to use it. Overall, pediatrics at risk of CDI recurrence should be evaluated, such as reviewing current antibiotics for potential discontinuation. Future studies evaluating the epidemiology and treatment for CDI in Saudi children are needed.

Abstract
OBJECTIVE Few data are available to quantify the Clostridioides difficile infection (CDI) burden in US adults depending on Medicaid insurance status; thus, we sought to contribute to this body of information. METHODS Retrospective cohort study to identify adults with codes for CDI from 2011 to 2017 in MarketScan commercial and Medicaid databases (for those aged 25-64 years) and the CMS Medicare database (for those aged ≥65 years). CDI was categorized as healthcare-facility-associated (HCA-CDI) and community-associated CDI (CA-CDI). CDI incidence rates were compared by year, insurer, and age group. RESULTS The overall CDI incidence in the elderly was 3.1-fold higher in persons insured by Medicare plus Medicaid than in those insured by Medicare only (1,935 vs 618 per 100,000 person years (PY)), and the CDI incidence was 2.7-fold higher in younger adults with Medicaid compared to commercial insurance (195 vs 73 per 100,000 PY). From 2011 to 2017, HCA-CDI rates declined in the younger Medicaid population (124.0 to 95.2 per 100,000 PY; P < .001) but were stable in those commercially insured (25.9 to 24.8 per 100,000 PY; P = .33). In the elderly HCA-CDI rates declined from 2011 to 2017 in the Medicare-only population (403 to 318 per 100,000 PY; P < .001) and the Medicare plus Medicaid population (1,770 to 1,163 per 100,000 PY; P < .002). Persons with chronic medical conditions and those with immunocompromising conditions insured by Medicaid had 2.8- and 2.7-fold higher CDI incidence compared to the commercially insured population, respectively. The incidence of CDI was lowest in Medicaid and commercially insured younger adults without chronic medical or immunosuppressive conditions (67.5 and 45.6 per 100,000 PY, respectively). CONCLUSIONS Although HCA-CDI incidence decreased from 2011 to 2017 in elderly and younger adults insured by Medicaid, the burden of CDI remains much higher in low-income adults insured by Medicaid.

Abstract
BACKGROUND This study aims to demonstrate the utility of a threshold logistic approach to identifying thresholds for specific antibiotic use associated with Clostridioides difficile infection (CDI) in an English teaching hospital. METHODS A combined approach of nonlinear modeling and logistic regression, named threshold logistic, was used to identify thresholds and risk scores in hospital-level antibiotic use associated with hospital-onset, healthcare-associated (HOHA) CDI cases. RESULTS Using a threshold logistic regression approach, an incidence greater than 0.2645 cases/1000 occupied bed-days (OBD; 85th percentile) was determined as the cutoff rate to define a critical (high) incidence rate of HOHA CDI. Fluoroquinolones and piperacillin-tazobactam were found to have thresholds at 84.8 and 54 defined daily doses (DDD)/1000 OBD, respectively. Analysis of data allowed calculating risk scores for HOHA CDI incidence rates exceeding the 85th percentile, i.e. entering critical incidence level. The threshold-logistic model also facilitated performing 'what-if scenarios' on future values of fluoroquinolones and piperacillin-tazobactam use to understand how HOHA CDI incidence rates may be affected. CONCLUSION Using threshold logistic analysis, critical incidence levels and antibiotic use targets to control HOHA CDI were determined. Threshold logistic models can be used to inform and enhance the effective design and implementation of antimicrobial stewardship programs.

Abstract
In this retrospective cohort of adult hematology-oncology and transplant patients, discontinuation of universal gloving did not result in significant changes in rates of central line-associated bloodstream infection, Clostridioides difficile infection, or vancomycin-resistant Enterococcus colonization. Active surveillance and subsequent isolation may be a viable alternative strategy to universal precautions.

Abstract
BACKGROUND Clostridioides difficile is the leading cause of hospital-onset diarrhea and is associated with increased lengths of stay and mortality. While some hospitals have successfully reduced the burden of C. difficile infection (CDI), many still struggle to reduce hospital-onset CDI. Nurses-because of their close proximity to patients-are an important resource in the prevention of hospital-onset CDI. OBJECTIVE Determine whether there is an association between the nurse work environment and hospital-onset CDI. METHODS Survey data of 2016 were available from 15,982 nurses employed in 353 acute care hospitals. These data, aggregated to the hospital level, provided measures of the nurse work environments. They were merged with 2016 hospital-onset CDI data from Hospital Compare, which provided our outcome measure-whether a hospital had a standardized infection ratio (SIR) above or below the national average SIR. Hospitals above the average SIR had more infections than predicted when compared to the national average. RESULTS In all, 188 hospitals (53%) had SIRs higher than the national average. The odds of hospitals having higher than average SIRs were significantly lower, with odds ratios ranging from 0.35 to 0.45, in hospitals in the highest quartile for all four nurse work environment subscales (managerial support, nurse participation in hospital governance, physician-nurse relations, and adequate staffing) than in hospitals in the lowest quartile. CONCLUSIONS Findings show an association between the work environment of nurses and hospital-onset CDI. A promising strategy to lower hospital-onset CDI and other infections is a serious and sustained commitment by hospital leaders to significantly improve nurse work environments.

Abstract
Clostridial enteric diseases, called enterotoxemia, are caused by Clostridium perfringens toxinotypes in sheep and other ruminants. This study aimed to describe the molecular characterization of C. perfringens isolates in diarrhoeic sheep (Ovis aries) flocks in the southeast of Iran. Fecal/intestinal samples were collected from diarrhoeic (n=116), dead (n= 13), and healthy (n=63) sheep over four years (2016-2020) and subjected to bacteriological and molecular examinations. The C. perfringens isolates were typed by polymerase chain reaction targeting genes, namely 16SrRNA, CPA, CPB, ETX, IAP, CPE, and NetB. The overall prevalence of C. perfringens was 28.6% among the studied sheep, and there was a significant relationship between its isolation rate and diarrhea (P<0.001). The C. perfringens isolation rate also decreased with animal age (P=0.012) and was significantly higher in late winter and spring (P=0.000). The most prevalent toxinotypes were types A (52.4%), D (22.2%), and F (18.5%), in that order. Moreover, C, G, and B types were found in 4.2%, 1.6%, and 1.1% of the isolates, respectively, and no type E was detected. The CPE gene was detected in 32.3% of all isolates, and the diarrhoeic sheep were most likely to yield CPE+ strains of C. perfringens (93.1%). These findings highlight the importance of CPE+ strains of C. perfringens in sheep enteritis and suggest that the high presence of type F needs to be considered in new clostridial vaccines containing this toxinotype. It is noteworthy that the present study reported the isolation of C. perfringens type F, type G, and the CPE+ strains of type B from diarrhoeic sheep for the first time.

Abstract
BACKGROUND & AIMS Inflammatory bowel disease (IBD) is a widespread gastrointestinal inflammatory disorder with globally increasing incidence. Clostridioides difficile infection (CDI) often occurs in patients with intestinal dysbiosis, such as after antibiotic therapy. Patients with IBD have increased incidence of CDI and the clinical outcome of IBD is reportedly worsened by CDI. However, the underlying reasons remain poorly understood. METHODS We performed a retrospective single-center and a prospective multicenter analysis of CDI in patients with IBD, including genetic typing of C difficile isolates. Furthermore, we performed a CDI mouse model to analyze the role of the sorbitol metabolization locus that we found distinguished the main IBD- and non-IBD-associated sequence types (STs). Moreover, we analyzed sorbitol concentration in the feces of patients with IBD and healthy individuals. RESULTS We detected a significant association of specific lineages with IBD, particularly increased abundance of ST54. We found that in contrast to the otherwise clinically predominant ST81, ST54 harbors a sorbitol metabolization locus and was able to metabolize sorbitol in vitro and in vivo. Notably, in the mouse model, ST54 pathogenesis was dependent on intestinal inflammation-induced conditions and the presence of sorbitol. Furthermore, we detected significantly increased sorbitol concentrations in the feces of patients with active IBD vs patients in remission or healthy controls. CONCLUSIONS Sorbitol and sorbitol utilization in the infecting C difficile strain play major roles for the pathogenesis and epidemiology of CDI in patients with IBD. CDI in patients with IBD may thus be avoided or improved by elimination of dietary sorbitol or suppression of host-derived sorbitol production.

Abstract
BACKGROUND The incidence of Clostridioides difficile infection (CDI) is high in ulcerative colitis and is associated with disease flares and adverse outcomes. However, the data on the dynamics of CDI in patients with acute severe ulcerative colitis (ASUC) is rather scarce. We evaluated the prevalence of CDI in patients with ASUC. METHODS This retrospective analysis of a prospectively maintained cohort admitted to the All India Institute of Medical Sciences, India, from May 2016 to December 2021, included patients with ASUC (as per Truelove and Witts criteria) who were tested for CDI. CDI testing was performed using enzyme-linked immunoassay for toxins A and B. Risk factors for developing CDI were analyzed along with short-term outcomes of ASUC. Steroid failure was defined as the need for medical rescue therapy or colectomy. RESULTS Total 153 patients with ASUC were included (mean age 34.92 ± 12.24 years; males 56.2%; disease duration 36 (IQR: 16-55.5) months, pancolitis 67.3%). Ninety-eight (63.4%), 72 (47%) and 10 (6.5%) patients, respectively, had received steroids, azathioprine and biologics in the past. Forty patients (26.14%) had a prior history of ASUC. Among risk factors for CDI, 14% of the patients had prior admission within 30 days, 22.2% had a recent history of antibiotics and 3.9% had long-term non-steroidal anti-inflammatory drug intake. Only one sample was positive for Clostridioides difficile toxin assay. Tissue Cytomegalovirus DNA-PCR positivity was noted in 57 patients (37.3%). Fifty-seven patients (37.3%) had steroid failure, 35 required medical rescue therapy and 30 (19.6%) required colectomy (eight after medical rescue therapy failure). CONCLUSION Despite antecedent risk factors for CDI, the overall prevalence of CDI in ASUC was low and the outcomes were determined by underlying disease severity.

Abstract
Clostridioides difficile infection in older adults can result in severe infection, difficulty in treating, and complicated disease process, yet few studies have examined the characteristics of hospitalized older adults and recurrent Clostridioides difficile infection. A retrospective cohort study was conducted to explore the characteristics of hospitalized adults 55 years and older with initial Clostridioides difficile infection and recurrences by extracting routinely documented data in the electronic health record. A sample of 1,199 admissions on 871 patients was included, with a recurrence rate of 23.9% ( n = 208). During the first admission, there were 79 deaths (9.1%). Clostridioides difficile infection recurrence was more prevalent in patients between 55 and 64 years old, and if discharged to a skilled nursing facility or with home health services. Chronic diseases significantly more prevalent in recurrent Clostridioides difficile infection included hypertension, heart failure, and chronic kidney disease. On initial admission, no laboratory abnormalities were significantly associated with recurrent Clostridioides difficile infection. This study indicates the need for utilizing routinely captured electronic health record data during acute hospitalizations to aid in targeting care to reduce morbidity, mortality, and recurrence.

Abstract
Recurrent Clostridioides difficile infection (RCDI) causes an increased burden on the healthcare system. We calculated RCDI incidence and identified factors associated with RCDI cases in New Haven County, Connecticut, USA, during 2015-2020 by using data from population-based laboratory surveillance. A subset of C. difficile cases had complete chart reviews conducted for RCDI and potentially associated variables. RCDI was defined as a positive C. difficile specimen occurring 2-8 weeks after incident C. difficile infection. We compared cases with and without RCDI by using multiple regression. RCDI occurred in 12.0% of 4,301 chart-reviewed C. difficile cases, showing a U-shaped time trend with a sharp increase in 2020, mostly because of an increase in hospital-onset cases. Malignancy (odds ratio 1.51 [95% CI 1.11-2.07]) and antecedent nitrofurantoin use (odds ratio 2.37 [95% CI 1.23-4.58]) were medical risk factors for RCDI. The 2020 increase may reflect the impact of the COVID-19 pandemic.

Abstract
Although Clostridioides difficile infection (CDI) incidence is high in the United States, standard-of-care (SOC) stool collection and testing practices might result in incidence overestimation or underestimation. We conducted diarrhea surveillance among inpatients >50 years of age in Louisville, Kentucky, USA, during October 14, 2019-October 13, 2020; concurrent SOC stool collection and CDI testing occurred independently. A study CDI case was nucleic acid amplification test‒/cytotoxicity neutralization assay‒positive or nucleic acid amplification test‒positive stool in a patient with pseudomembranous colitis. Study incidence was adjusted for hospitalization share and specimen collection rate and, in a sensitivity analysis, for diarrhea cases without study testing. SOC hospitalized CDI incidence was 121/100,000 population/year; study incidence was 154/100,000 population/year and, in sensitivity analysis, 202/100,000 population/year. Of 75 SOC CDI cases, 12 (16.0%) were not study diagnosed; of 109 study CDI cases, 44 (40.4%) were not SOC diagnosed. CDI incidence estimates based on SOC CDI testing are probably underestimated.

Abstract
Clostridioides difficile infection (CDI) is common after allogeneic hematopoietic cell transplantation (alloHCT). The determination of incidence, risk factors, and impact of CDI on alloHCT outcomes is an unmet need. The study examines all patients aged 2 years and older who received first alloHCT for acute myeloid leukemia (AML), acute lymphocytic leukemia (ALL), or myelodysplastic syndrome (MDS) between 2013 and 2018 at US centers and reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) data registry. In total, 826 patients with CDI and 6723 controls from 127 centers were analyzed. The cumulative incidence of CDI by day 100 was 18.7% (99% CI: 15-22.7%) and 10.2% (99% CI: 9.2-11.1%) in pediatric and adult patients, respectively, with a median time to diagnosis at day +13. CDI was associated with inferior overall survival (OS) (p = 0.0018) and a 2.58-fold [99% CI: 1.43-4.66; p < 0.001] increase in infection-related mortality (IRM). There was a significant overlap in the onset of acute graft versus host disease (aGVHD) and CDI. IRM increased to >4 fold when CDI + aGVHD was considered. Despite advances in the management of CDI, increased IRM and decreased OS still results from CDI.

Abstract
BACKGROUND Clostridium difficile (C. difficile) is a Gram-positive, anaerobic, spore-forming bacillus that can cause pseudomembranous colitis and other C. difficile-associated diseases, resulting in significant morbidity and mortality. The incidence and clinical features vary by geography. METHODS In this cross-sectional study, we examined the incidence and clinical features of C. difficile infection (CDI) within a 2,900-bed academic medical center in a southern area of China from January 1, 2017, to December 31, 2020. All adult inpatients (aged ≥ 18 years) who submitted loose stool samples for C. difficile testing over this period were considered for the study. RESULTS This cross-sectional study showed that the average incidence of CDI was 2.07 cases/100,000 hospital patient-days. The mean age of these inpatients was 71.21 ± 2.83 years (range 30 - 93 years), and 83.61% (51/61) were treated in medical units. We found that 85.25% (52/61) of inpatients with CDI were aged > 60 years. Multivariate logistic regression analysis revealed that age > 60 years, and admission to the geriatric treatment unit or neurosurgery treatment unit were indeed independent risk factors for CDI in inpatients. CONCLUSIONS The incidence of CDI in the southern area of China was low. Age > 60 years, and treatment in geriatric or neurosurgery units were independent risk factors for CDI inpatients.

Abstract
BACKGROUND Antimicrobial susceptibility testing (AST) is not routinely performed for Clostridioides difficile and data evaluating minimum inhibitory concentrations (MICs) are limited. We performed AST and whole genome sequencing (WGS) for 593 C. difficile isolates collected between 2012 and 2017 through the Centers for Disease Control and Prevention's Emerging Infections Program. METHODS MICs to 6 antimicrobial agents (ceftriaxone, clindamycin, meropenem, metronidazole, moxifloxacin, and vancomycin) were determined using the reference agar dilution method according to Clinical and Laboratory Standards Institute guidelines. Whole genome sequencing was performed on all isolates to detect the presence of genes or mutations previously associated with resistance. RESULTS Among all isolates, 98.5% displayed a vancomycin MIC ≤2 μg/mL and 97.3% displayed a metronidazole MIC ≤2 μg/mL. Ribotype 027 (RT027) isolates displayed higher vancomycin MICs (MIC50: 2 μg/mL; MIC90: 2 μg/mL) than non-RT027 isolates (MIC50: 0.5 μg/mL; MIC90: 1 μg/mL) (P < .01). No vanA/B genes were detected. RT027 isolates also showed higher MICs to clindamycin and moxifloxacin and were more likely to harbor associated resistance genes or mutations. CONCLUSIONS Elevated MICs to antibiotics used for treatment of C. difficile infection were rare, and there was no increase in MICs over time. The lack of vanA/B genes or mutations consistently associated with elevated vancomycin MICs suggests there are multifactorial mechanisms of resistance. Ongoing surveillance of C. difficile using reference AST and WGS to monitor MIC trends and the presence of antibiotic resistance mechanisms is essential.

Abstract
Patients with inflammatory bowel disease (IBD) have a higher incidence of Clostridioides difficile infection (CDI). Previous studies have demonstrated negative clinical outcomes in IBD patients with CDI compared to patients without CDI. The clinical presentation of CDI is indistinguishable from IBD exacerbation, thus posing a frequent clinical dilemma on the role of Clostridioides infection in the testing, diagnosis, and treatment of these patients. To compare clinical outcomes of CDI in patients with IBD to those without IBD. Retrospective cohort of adult patients admitted to Rabin Medical Center Israel between the years 2014 and 2020 with a concurrent diagnosis of IBD and CDI. Matching 1:2 was performed between the IBD patients and the non-IBD population with respect to age and sex. Sixty-seven patients with IBD and 134 patients without IBD were included in the study. The groups' median age was 40.6 (interquartile range [IQR] of 29.8-68.9), with 45.8% male and 54.2% female. The non-IBD group had a higher Charlson score with 2 (IQR 0; 5) versus 0 (IQR 0; 4) in the IBD group (P value <.01). Patients with IBD had more exposure to systemic antibiotics, 71.1% versus 26.3% (P value <.01). In a multivariable analysis we found no difference in 90-day mortality and rate of relapse between the 2 study groups with an odds ratio of 1.709 (95% confidence interval 0.321-9.905) and odds ratio of 0.209 (95% confidence interval 0.055-1.513) respectively. In our cohort patients with IBD who present with diarrhea and concomitant CDI have similar rates of relapse and mortality compared with patients without IBD.
