Danielsen AS, Franconeri L, Page S, Myhre AE, Tornes RA, Kacelnik O, Bjørnholt JV. Clinical outcomes of antimicrobial resistance in cancer patients: a systematic review of multivariable models. BMC Infect Dis 2023; 23:247. [PMID: 37072711 PMCID: PMC10114324 DOI: 10.1186/s12879-023-08182-3] [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: 07/27/2022] [Accepted: 03/17/2023] [Indexed: 04/20/2023] Open
Abstract
BACKGROUND Infections are major causes of disease in cancer patients and pose a major obstacle to the success of cancer care. The global rise of antimicrobial resistance threatens to make these obstacles even greater and hinder continuing progress in cancer care. To prevent and handle such infections, better models of clinical outcomes building on current knowledge are needed. This internally funded systematic review (PROSPERO registration: CRD42021282769) aimed to review multivariable models of resistant infections/colonisations and corresponding mortality, what risk factors have been investigated, and with what methodological approaches. METHODS We employed two broad searches of antimicrobial resistance in cancer patients, using terms associated with antimicrobial resistance, in MEDLINE and Embase through Ovid, in addition to Cinahl through EBSCOhost and Web of Science Core Collection. Primary, observational studies in English from January 2015 to November 2021 on human cancer patients that explicitly modelled infection/colonisation or mortality associated with antimicrobial resistance in a multivariable model were included. We extracted data on the study populations and their malignancies, risk factors, microbial aetiology, and methods for variable selection, and assessed the risk of bias using the NHLBI Study Quality Assessment Tools. RESULTS Two searches yielded a total of 27,151 unique records, of which 144 studies were included after screening and reading. Of the outcomes studied, mortality was the most common (68/144, 47%). Forty-five per cent (65/144) of the studies focused on haemato-oncological patients, and 27% (39/144) studied several bacteria or fungi. Studies included a median of 200 patients and 46 events. One-hundred-and-three (72%) studies used a p-value-based variable selection. Studies included a median of seven variables in the final (and largest) model, which yielded a median of 7 events per variable. An in-depth example of vancomycin-resistant enterococci was reported. CONCLUSIONS We found the current research to be heterogeneous in the approaches to studying this topic. Methodological choices resulting in very diverse models made it difficult or even impossible to draw statistical inferences and summarise what risk factors were of clinical relevance. The development and adherence to more standardised protocols that build on existing literature are urgent.

Risk factors for Clostridioides difficile infection in children: A systematic review and meta-analysis. J Hosp Infect 2022; 130:112-121. [PMID: 36108754 DOI: 10.1016/j.jhin.2022.09.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Revised: 08/30/2022] [Accepted: 09/01/2022] [Indexed: 11/21/2022]
Abstract
BACKGROUND Clostridioides difficile infection (CDI) is considered an urgent threat to human health by the US Centers for Disease Control and Prevention. In recent years, C. difficile is increasingly being reported as a cause of gastrointestinal diseases in children, and the prevalence of hospital-acquired CDI (HA-CDI) and community-acquired CDI (CA-CDI) in children is increasing. AIM To perform a systematic review and meta-analysis of risk factors for Clostridioides difficile infection (CDI) in children. METHODS MEDLINE/PubMed, EMBASE, Web of Science, Scopus, OVID, China National Knowledge Infrastructure, Wanfang (Chinese), SinoMed (Chinese), and Weipu (Chinese) databases were searched from inception through January 12, 2022. Observational studies (cohort, case-control, and cross-sectional) on CDI in children were included in the analysis. Data were pooled using a fixed or random-effects model, and odds ratios (ORs) were calculated. FINDINGS A total of 25 observational studies were included in the analysis. Prior antibiotic exposure (OR, 1.93; 95% confidence interval (CI), 1.25-2.97), prolonged hospitalization (OR, 14.68; 95% CI, 13.24-16.28), hospitalization history (OR, 3.67; 95% CI, 1.91-7.06), gastric acid suppressants (OR, 1.96; 95% CI, 1.41-2.73), male gender (OR, 1.18; 95% CI, 1.05-1.32), neoplastic disease (OR, 3.40; 95% CI, 2.85-4.07), immunodeficiency (OR, 4.18; 95% CI, 3.25-5.37), solid organ transplantation (OR, 4.56; 95% CI, 3.95-5.27) and enteral feeding (OR, 2.21; 95% CI, 1.15-4.62) were associated with an increased risk of CDI. CONCLUSION This systematic review and meta-analysis provides further evidence for the susceptibility factors of CDI to improve clinicians' awareness of CDI and effectively prevent C. difficile associated diarrhoea in children.

Abstract
OBJECTIVES Clostridioides difficile is an important pathogen of healthcare-associated gastrointestinal infections. Recently, an increased number of C. difficile infection (CDI) surveillance data has been reported from Asia. The aim of this review is to summarize the data on the prevalence, distribution and molecular epidemiology of CDI in the Middle and the Far East. METHODS Literature was drawn from a search of PubMed up to September 30, 2021. RESULTS The meta-analysis of data from 111 studies revealed the pooled CDI prevalence rate in the Middle and the Far East of 12.4% (95% CI 11.4-13.3); 48 studies used PCR for CDI laboratory diagnoses. The predominant types (RT)/sequence type (ST) differ between individual countries (24 studies, 14 countries). Frequently found RTs were 001, 002, 012, 017, 018 and 126; RT017 was predominant in the Far East. The epidemic RT027 was detected in 8 countries (22 studies), but its predominance was reported only in three studies (Israel and Iran). The contamination of vegetable and meat or meat products and/or intestinal carriage of C. difficile in food and companion animals have been reported; the C. difficile RTs/STs identified overlapped with those identified in humans. CONCLUSIONS A large number of studies on CDI prevalence in humans from the Middle and the Far East have been published; countries with no available data were identified. The number of studies on C. difficile from non-human sources is limited. Comparative genomic studies of isolates from different sources are needed.

Abstract
Objectives To describe the epidemiology and risk factors for Clostridioides difficile (C. difficile) colonization among young children in eight low-resource settings. Methods We tested 41 354 monthly non-diarrhoeal and diarrhoeal stools for C. difficile toxin genes (TcdA and TcdB) using quantitative PCR (qPCR) in 1715 children from birth to age two years in a multisite birth cohort study. We estimated the prevalence, cumulative incidence, and seasonality of C. difficile colonization and investigated the associations of C. difficile detection with risk factors of infection, markers of enteropathy, and growth. Results The prevalence of C. difficile detection was lower in diarrhoeal (2.2%; n = 151/6731) compared to non-diarrhoeal stools (6.1%; n = 2106/34 623). By 24 months of age, the cumulative incidence of C. difficile varied widely by site, with 17.9% (n = 44; Pakistan) to 76.3% (n = 148; Peru) of children having at least one positive stool. Only Bangladesh and Pakistan had seasonal differences in C. difficile detection. Female sex (adjusted risk ratio (aRR): 1.18; 95% CI: 1.02–1.35), cephalosporin use in the past 15 days (aRR: 1.73; 95% CI: 1.39–2.16), and treated water (aRR: 1.24; 95% CI: 1.02–1.50) were risk factors for C. difficile positivity. The presence of C. difficile was significantly associated with elevated faecal myeloperoxidase, neopterin, and α-1-antitrypsin, but no associations were found between C. difficile and child growth at 24 months of age. Discussion C. difficile colonization among children ages 0–2 years was variable across low-resource settings. Significant elevation of intestinal inflammation and barrier disruption markers associated with C. difficile detection suggests a subclinical impact of colonization.

Abstract
Clostridioides difficile infection is very common in immunocompromised children. Management is confounded by frequent asymptomatic colonization, multiple alternative etiologies for gastrointestinal symptoms, and high rates of relapse. Important considerations include indications for testing, appropriate choice of diagnostic tests, antibiotic therapy for initial and subsequent episodes, and primary and secondary prevention.

Abstract
BACKGROUND The epidemiology and clinical course of Clostridioides difficile infection (CDI) in children, especially with cancer, are poorly defined. We aim to describe the epidemiology, clinical features and outcomes of CDI and to identify risk factors for recurrence in a pediatric oncology center. METHODS This is a retrospective cohort study of CDI in pediatric oncology and hematopoietic stem cell transplant (HSCT) patients in 2016 and 2017. CDI cases were identified by positive C. difficile test in symptomatic patients. CDI episodes were classified as incident, duplicate or recurrent and community-onset, hospital-onset or community-onset healthcare facility-associated. Data about clinical course and outcomes were abstracted. Risk factors for CDI recurrence were assessed by logistic regression. RESULTS One hundred seventy-eight patients 1 year of age and older developed 291 CDI episodes; 78% were incident and 22% recurrent. Underlying diagnoses were leukemia/lymphoma (57%) and solid/brain tumors (41%); 30% were HSCT recipients. Antibiotics, chemotherapy, antacids, steroids and laxatives were received by 96%, 82%, 70%, 47% and 15%, respectively. Half of the patients were neutropenic. Twenty-two percent of outpatients with CDI required hospitalization. Chemotherapy was delayed in 25%. There were no intensive care unit admissions nor deaths due to CDI. Exposure to H2-antagonists was identified as an independent risk factor for CDI recurrence. CONCLUSIONS Although CDI in pediatric oncology and HSCT patients was associated with chemotherapy delay and hospitalization in approximately a quarter of patients, it was not associated with morbidity or mortality because patients had no attributable intensive care unit admission nor death. H2-antagonists are independent risk factors for CDI recurrence.

Abstract
BACKGROUND Clostridioides difficile infection (CDI) is a significant source of morbidity in pediatric cancer patients. Few reports to date have evaluated risk factors and short-term outcomes for this population. METHODS We retrospectively evaluated pediatric oncology admissions at St Louis Children's Hospital from 2009 to 2018. All inpatient cases of diagnosed initial CDI were identified. We aimed to investigate the prevalence of CDI and associated risk factors, including coadmission with another patient with CDI, and to evaluate short-term outcomes including length of stay and delays in subsequent scheduled chemotherapy. RESULTS Review of 6567 admissions from 952 patients revealed 109 CDI cases (11.4% of patients). Patients with leukemia or lymphoma, compared to those with solid tumors, were more likely to have CDI (odds ratio [OR], 3 [95% CI, 1.4-6.6], and 3 [95% CI, 1.3-6.8], respectively). Autologous hematopoietic stem cell transplant (HSCT) was also a risk factor (OR, 3.5 [95% CI, 1.7-7.4]). Prior antibiotic exposure independently increased the risk for CDI (OR, 3.0 [95% CI, 1.8-4.8]). Concurrent admission with another patient with CDI also significantly increased the risk (OR, 84.7 [95% CI, 10.5-681.8]). In contrast to previous reports, exposure to acid-suppressing medications decreased the risk for CDI (OR, 0.5 [95% CI, .3-.7]). CDI was associated with increased length of stay (mean difference, 8 days [95% CI, 4.6-11.4]) and prolonged delays for subsequent chemotherapy (mean difference, 1.4 days [95% CI, .1-2.7]). CONCLUSIONS CDI in pediatric oncology patients significantly prolongs hospitalization and delays chemotherapy treatment plans. Interventions to control CDI will improve the care of pediatric oncology patients.

Abstract
Background Clostridium difficile infection (CDI) has an increasing pediatric prevalence worldwide. However, molecular characteristics of C. difficile in Chinese children with acute gastroenteritis have not been reported. Methods A five-year cross-sectional study was conducted in a tertiary children’s hospital in Zhejiang. Consecutive stool specimens from outpatient children with acute gastroenteritis were cultured for C. difficile, and isolates then were analyzed for toxin genes, multi-locus sequence type and antimicrobial resistance. Diarrhea-related viruses were detected, and demographic data were collected. Results A total of 115 CDI cases (14.3%), and 69 co-infected cases with both viruses and toxigenic C. difficile, were found in the 804 stool samples. The 186 C. difficile isolates included 6 of toxin A-positive/toxin B-positive/binary toxin-positive (A+B+CDT+), 139 of A+B+CDT−, 3 of A−B+CDT+, 36 of A−B+CDT− and 2 of A−B−CDT−. Sequence types 26 (17.7%), 35 (11.3%), 39 (12.4%), 54 (16.7%), and 152 (11.3%) were major genotypes with significant differences among different antimicrobial resistances (Fisher's exact test, P < 0.001). The A−B+ isolates had significantly higher resistance, compared to erythromycin, rifampin, moxifloxacin, and gatifloxacin, than that of the A+B+ (χ2 = 7.78 to 29.26, P < 0.01). The positive CDI rate in infants (16.2%) was significantly higher than that of children over 1 year old (10.8%) (χ2 = 4.39, P = 0.036). Conclusions CDI has been revealed as a major cause of acute gastroenteritis in children with various genotypes. The role of toxigenic C. difficile and risk factors of CDI should be emphatically considered in subsequent diarrhea surveillance in children from China.

Abstract
AbstractObjective:To summarize risk factors for Clostridioides (formerly Clostridium) difficile infection (CDI) in hospitalized pediatric patients as determined by previous observational studies.Design:Meta-analysis and systematic review.Patients:Studies evaluating risk factors for CDI in pediatric inpatients were eligible for inclusion.Method:We systematically searched MEDLINE, Web of Science, Scopus, and EMBASE for subject headings and text words related to CDI and pediatrics from 1975 to 2017. Two of the investigators independently screened studies, extracted and compiled data, assessed study quality, and performed the meta-analysis.Results:Of the 2,033 articles screened, 14 studies reporting 10,531,669 children met the inclusion criteria. Prior antibiotic exposure (odds ratio [OR], 2.14; 95% confidence interval [CI], 1.31–3.52) and proton pump inhibitor (PPI) use (OR, 1.33; 95% CI, 1.07–1.64) were associated with an increased risk of CDI in children. Subgroup analyses using studies reporting only adjusted results suggested that prior antibiotic exposure is not a significant risk factor for CDI. H2 receptor antagonist (H2RA) use (OR, 1.36; 95% CI, 0.31–5.98) and that female gender (OR, 0.87; 95% CI, 0.74–1.03) did not play a significant role as a risk factor for developing CDI.Conclusion:Prior antibiotic exposure appears to be an important risk factor for CDI based on the combined analysis but not significant using adjusted studies. PPI use was associated with an increased risk of CDI. Judicious and appropriate use of antibiotics and PPIs may help reduce the risk of CDI in this vulnerable population.

Abstract
Clostridium difficile infection (CDI) continues to have clinical and economic impact across all health care settings. Pediatrics accounts for a small percentage of worldwide infection; however, screening and diagnosis are confounded by asymptomatic colonization in young infants. Metronidazole and oral vancomycin have historically been the agents used to manage CDI in both pediatrics and adults. Newer agents and alternative therapies, such as fecal microbiota transplantation, may offer additional benefit. Recent guidelines updates from the Infectious Diseases Society of America and the Society for Healthcare Epidemiology of America separate pediatric and adult recommendations for epidemiology, diagnosis, and treatment. This review will discuss the risk factors, management, prevention, and updated guideline recommendations for CDI in the pediatric population.

Abstract
Abstract To increase understanding of the epidemiology, risks, consequences and resource utilization of Clostridium difficile infection (CDI) in Japan, a systematic literature review was undertaken of relevant publications from January 2006 to November 2017. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and methods, 55 articles met the criteria for full review. The majority (58%) of studies were from a single site, with the most recent data from 2015. The incidence, reported prevalence and recurrence rate of CDI in Japan were 0.8–4.71/10,000 patient-days, 0.3–5.5/1000 patients and 3.3–27.3%, respectively, and varied according to setting, population, CDI definition and detection method. Most C. difficile isolates associated with CDI in Japan were toxin A+B+, with a low level of C. difficile binary toxin-positive (CDT+) strains (0–6.8% reported across studies). The most common C. difficile PCR ribotypes associated with infection in Japan were smz/018, 002, 052 and 369. Data regarding the impact of CDI on length of hospital stay were limited. Reported all-cause mortality in patients with CDI ranged from 3.4 to 15.1% between 2007 and 2013. Two studies assessed risk factors for CDI recurrence, identifying malignant disease, intensive care unit hospitalization and use of proton pump inhibitors as factors increasing the risk of initial and/or recurrent CDI. No study analyzed initial CDI treatment in relation to recurrence.
