Abstract
Objective To describe the epidemiology of healthcare-associated Clostridioides difficile infection (HA-CDI) in two Québec hospitals in Canada following the 2003 epidemic and to evaluate the impact of antibiotic stewardship on the incidence of HA-CDI and the NAP1/027 strain. Design Time-series analysis. Setting Two Canadian tertiary care hospitals based in Montréal, Québec. Patients Patients with a positive assay for toxigenic C. difficile were identified through infection control surveillance. All cases of HA-CDI, defined as symptoms occurring after 72 hours of hospital admission or within 4 weeks of hospitalization, were included. Methods The incidence of HA-CDI and antibiotic utilization from 2003 to 2020 were analyzed with available C. difficile isolates. The impact of antibiotic utilization on HA-CDI incidence was estimated by a dynamic regression time-series model. Antibiotic utilization and the proportion of NAP1/027 strains were compared biannually for available isolates from 2010 to 2020. Results The incidence of HA-CDI decreased between 2003 and 2020 at both hospitals from 26.5 cases per 10,000 patient-days in 2003 to 4.9 cases per 10,000 patient-days in 2020 respectively. Over the study period, there were an increase in the utilization of third-generation cephalosporins and a decrease in usage of fluoroquinolones and clindamycin. A decrease in fluoroquinolone utilization was associated with a significant decrease in HA-CDI incidence as well as decrease in the NAP1/027 strain by approximately 80% in both hospitals. Conclusions Decreased utilization of fluoroquinolones in two Québec hospitals was associated with a decrease in the incidence of HA-CDI and a genotype shift from NAP1/027 to non-NAP1/027 strains.

Abstract
IMPORTANCE Testing for enteric bacterial pathogens in patients hospitalized for more than 3 days is almost always inappropriate. Our study validates the utility of the 3-day rule and the use of clinical decision support tools to decrease unnecessary testing of enteropathogenic bacteria other than C. difficile. Overriding the restriction was very low yield. Our study highlights the importance of diagnostic stewardship and further refines the criteria for allowing providers to override the restriction while monitoring the impact of the interventions.

Abstract
PURPOSE Postoperative diarrhea (PD) remains one of the significant complications. Only a few studies focused on PD after minimally invasive surgery. We aimed to investigate PD after minimally invasive gastrectomy for gastric cancer. METHODS A total of 1476 consecutive patients with gastric cancer undergoing laparoscopic or robotic gastrectomy between 2009 and 2019 at our institution were retrospectively reviewed. PD was defined as continuous diarrhea for ≥ 2 days, positive stool culture, or positive clostridial antigen test. The incidence, causes, and related clinical factors were analyzed. RESULTS Of the 1476 patients, the median age was 69 years. Laparoscopic and robotic approaches were performed in 1072 (72.6%) and 404 (27.4%), respectively. Postoperative complications with Clavien-Dindo classification grade of ≥ IIIa occurred in 108 (7.4%) patients. PD occurred in 89 (6.0%) patients. Of the 89 patients with PD, Clostridium difficile, enteropathogenic Escherichia coli, and methicillin-resistant Staphylococcus aureus were detected in 24 (27.0%), 16 (33.3%), and 7 (14.6%) patients, respectively. Multivariate analysis revealed that age ≥ 75 years (OR 1.62, 95% CI [1.02-2.60], p = 0.042) and postoperative complications (OR 6.04, 95% CI [3.54-10.32], p < 0.001) were independent risk factors for PD. In patients without complications, TG (OR 1.88) and age of ≥ 75 years(OR 1.71) were determined as independent risk factors. CONCLUSION The incidence of PD following minimally invasive gastrectomy for gastric cancer was 6.0%. Older age and TG were obvious risk factors in such a surgery, with the latter being a significant risk even in the absence of complications.

The effect of fiber supplementation on the prevention of diarrhea in hospitalized patients receiving enteral nutrition: A meta-analysis of randomized controlled trials with the GRADE assessment. Front Nutr 2022; 9:1008464. [PMID: 36505240 PMCID: PMC9733536 DOI: 10.3389/fnut.2022.1008464] [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: 07/31/2022] [Accepted: 10/27/2022] [Indexed: 11/27/2022] Open
Abstract
Introduction Enteral nutrition (EN) in hospitalized patients has several advantages. However, post-feeding diarrhea occurs frequently and has been linked to negative outcomes. The EN formula itself may have an impact on how diarrhea develops, and fiber supplements may theoretically help patients experience less diarrhea. This study aimed to thoroughly evaluate whether adding fiber to EN decreases the likelihood of developing diarrhea and whether different types of fibers pose different effects on diarrhea (PROSPERO CRD 42021279971). Methods We conducted a meta-analysis on fiber supplementation in hospitalized adult patients receiving EN. We thoroughly searched PubMed, Medline, Embase, Scopus, Web of Science, CENTRAL, and ClinicalTrials.gov databases from inception to 1 September 2022. Only randomized controlled trials (RCTs) were included. Pooled results on the incidence of diarrhea were calculated using a random-effects model. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was applied. Only fiber types from soy polysaccharides (n = 4), psyllium (n = 3), mixed soluble/insoluble fiber (mixed fiber, n = 3), pectin (n = 2), and partially hydrolyzed guar gum (PHGG, n = 2) were examined in the sensitivity analysis. Results Among the 4,469 titles found, a total of 16 RCTs were included. Overall, compared to fiber-free formulas, fiber supplementation reduced the occurrence of diarrhea in patients receiving EN by 36% (pooled risk ratio [RR] of 0.64 [95% confidence interval (CI): 0.49-0.82, p = 0.005; I 2 = 45%]), with GRADE showing the evidence of moderate certainty. Only mixed fiber and PHGG significantly decreased the incidence of diarrhea according to the sensitivity analyses for fiber types (RR 0.54, 95%CI: 0.39-0.75, I 2 = 0% and RR 0.47, 95%CI: 0.27-0.83, I 2 = 0%, respectively). The results for the remaining fiber types were unclear. Conclusion According to a meta-analysis, fiber supplements help lessen post-feeding diarrhea in hospitalized patients receiving EN. However, not all fiber types produced successful outcomes. Diarrhea was significantly reduced by PHGG and mixed soluble/insoluble fiber.

Abstract
At present, the dramatic rise in antimicrobial resistance (AMR) among important human bacterial pathogens is reaching a state of global crisis threatening a return to the pre-antibiotic era. AMR, already a significant burden on public health and economies, is anticipated to grow even more severe in the coming decades. Several licensed vaccines, targeting both bacterial (Haemophilus influenzae type b, Streptococcus pneumoniae, Salmonella enterica serovar Typhi) and viral (influenza virus, rotavirus) human pathogens, have already proven their anti-AMR benefits by reducing unwarranted antibiotic consumption and antibiotic-resistant bacterial strains and by promoting herd immunity. A number of new investigational vaccines, with a potential to reduce the spread of multidrug-resistant bacterial pathogens, are also in various stages of clinical development. Nevertheless, vaccines as a tool to combat AMR remain underappreciated and unfortunately underutilized. Global mobilization of public health and industry resources is key to maximizing the use of licensed vaccines, and the development of new prophylactic vaccines could have a profound impact on reducing AMR.

Abstract
BACKGROUND AND AIM Clostridium difficile-associated diarrhea (CDAD) and enteral nutrition (EN)-associated diarrhea are the most common recognized etiologies of nosocomial diarrhea. However, in clinical practice, the data regarding how each etiology contributes to the diarrheal episodes are limited. We identify the causes and factors associated with post-feeding diarrhea. METHODS Using the data of patients enrolled in "Effect of Psyllium Fiber Supplementation on Diarrhea Incidence in Enteral Tube-Fed Patients: A Prospective, Randomized, and Controlled Trial", the randomized controlled trial showed no difference in diarrheal incidences between fiber-added and fiber-free formulas. Hence, we analyzed the data of all enrolled patients. The causes of diarrhea were classified according to pre-specified definitions. The factors associated with diarrhea were analyzed using logistic regression. RESULTS Diarrhea was found in 37.3% (n = 31/83). The most common cause was medication associated (61.3%). CDAD and EN-associated diarrhea were found in only 9.7% and 6.5%, respectively. Patients with baseline albumin <3 g/dL and underlying cerebrovascular disease were more likely to develop diarrhea (adjusted odds ratio 5.70, 95% confidence interval 1.79-20.51, and adjusted odds ratio 10.83, 95% confidence interval 2.96-48.57, respectively). Compared with those without diarrhea, the length of hospital stay in CDAD patients was significantly longer (+23.1 days, P = 0.02), a trend of longer hospital stay in patients with diarrhea from other causes was observed (+3.2 days, P = 0.096). CONCLUSIONS Our study found that the most common cause of post-feeding diarrhea is medication associated. Review and cessation of possible drugs should be undertaken before EN modification. CDAD accounts for <10% of diarrhea causes, but it impacts the clinical outcome and should be identified and treated properly.

Abstract
Background Acute diarrheal illness in the United States is a significant cause of healthcare utilization and hospitalizations. For patients who develop diarrhea while hospitalized, testing for pathogens other than Clostridium difficile (C. difficile) using conventional stool testing is low yield. Newer testing modalities for infectious diarrhea such as the multiplex molecular stool testing provide an improved detection rate and a faster turn-around time compared to conventional stool testing. Methods We retrospectively examined the use of a multiplex molecular stool test at our institution for all hospital encounters over a two-year period to determine which organisms were identified ≤ 3 days and > 3 days after admission. Results A total of 2032 patients underwent multiplex molecular stool testing during the study period, with 1698 (83.6%) performed ≤ 3 days and 334 (16.3%) > 3 days after admission. An enteric non-C. difficile pathogen was identified more frequently when patients were tested ≤ 3 days after admission (350, 20.6%) as compared to > 3 days after admission (38, 11.4%, p<0.0001). Excluding coinfections, C. difficile was identified more frequently when patients were tested > 3 days after admission (64, 20.3%) versus another organism (30, 9.0%) (p<0.0001). Of those patients with a non-C. difficile pathogen identified > 3 days after admission, a bacterial pathogen amenable to treatment was only identified in 6% (21) of patients. Conclusion Multiplex molecular stool testing for patients tested > 3 days after admission is a low yield of information that could guide antimicrobial treatment decisions, and C. difficile testing is more useful in this clinical situation.

Laxative Use Does Not Preclude Diagnosis or Reduce Disease Severity in Clostridiodes difficile Infection. Clin Infect Dis 2021; 71:1472-1478. [PMID: 31584632 DOI: 10.1093/cid/ciz978] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2019] [Accepted: 10/01/2019] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND To optimize utility of laboratory testing for Clostridiodes difficile infection (CDI), the 2017 Infectious Diseases Society of America-Society for Healthcare Epidemiology of America (IDSA-SHEA) clinical practice guidelines recommend excluding patients from stool testing for C. difficile if they have received laxatives within the preceding 48 hours. Sparse data support this recommendation. METHODS Patients with new-onset diarrhea (≥3 bowel movements in any 24-hour period in the 48 hours before stool collection) and a positive stool C. difficile nucleic acid amplification test were enrolled. Laxative use within 48 hours before stool testing, severity of illness (defined by 4 distinct scoring methods), and clinical outcomes were recorded. RESULTS 209 patients with CDI were studied, 65 of whom had received laxatives. There were no significant differences in the proportion of patients meeting severe CDI criteria by 4 severity scoring methods in patients receiving versus not receiving laxatives (66.2% vs 56.3%, respectively; P = .224) by IDSA-SHEA, the primary scoring system. Similar rates of serious outcomes attributable to CDI, including death, intensive care unit admission, and colectomy, were observed in the laxative and no laxative groups. CONCLUSIONS Our study found similar rates of severe CDI and serious CDI-attributable clinical outcomes in CDI-diagnosed patients who did or did not receive laxatives. Precluding recent laxative users from CDI testing, as proposed by the IDSA-SHEA guideline, carries a potential for harm due to delayed diagnosis and treatment.

Abstract
Little information is available regarding the pathogens that cause diarrhea in hospitalized patients who also have various clinical problems. The purpose of this study was to determine the presence of pathogens in fecal samples of hospitalized patients all suffering diarrhea in addition to other problems in Mexico. Diarrheic stools from 240 patients were obtained in a third-level hospital in Monterrey, Mexico. PCR was used for the detection of Salmonella spp., Shigella spp., Campylobacter spp., Yersinia spp., Aeromonas spp., Clostridioides difficile, and norovirus GI and GII. The presence of trophozoites, cysts of protozoa, eggs, and/or helminth larvae was determined by microscopic observation. Of the 240 patients analyzed, 40.4% presented at least one of the pathogens analyzed. Norovirus was the pathogen most frequently found (28.6%), followed by bacteria (11.7%), and parasites (8.3%). The majority of co-infections were parasites + norovirus, and bacteria + norovirus. Norovirus was detected mainly in children aged 0 to 10 years (9/15, 60%). Patients aged 0-20 years did not present co-infections. Entamoeba coli and Entamoeba histolytica were the most common parasites, (8/240), and Salmonella was the most prevalent bacteria (10/240). This information can help design specific strategies useful for hospitalized people with a compromised status.

Abstract
BACKGROUND Although several risk factors for nosocomial diarrhea have been identified, the detail of association between these factors and onset of nosocomial diarrhea, such as degree of importance or temporal pattern of influence, remains unclear. We aimed to determine the association between risk factors and onset of nosocomial diarrhea using machine learning algorithms. METHODS We retrospectively collected data of patients with acute cerebral infarction. Seven variables, including age, sex, modified Rankin Scale (mRS) score, and number of days of antibiotics, tube feeding, proton pump inhibitors, and histamine 2-receptor antagonist use, were used in the analysis. We split the data into a training dataset and independant test dataset. Based on the training dataset, we developed a random forest, support vector machine (SVM), and radial basis function (RBF) network model. By calculating an area under the curve (AUC) of the receiver operating characteristic curve using 5-fold cross-validation, we performed feature selection and hyperparameter optimization in each model. According to their final performances, we selected the optimal model and also validated it in the independent test dataset. Based on the selected model, we visualized the variable importance and the association between each variable and the outcome using partial dependence plots. RESULTS Two-hundred and eighteen patients were included. In the cross-validation within the training dataset, the random forest model achieved an AUC of 0.944, which was higher than in the SVM and RBF network models. The random forest model also achieved an AUC of 0.832 in the independent test dataset. Tube feeding use days, mRS score, antibiotic use days, age and sex were strongly associated with the onset of nosocomial diarrhea, in this order. Tube feeding use had an inverse U-shaped association with the outcome. The mRS score and age had a convex downward and increasing association, while antibiotic use had a convex upward association with the outcome. CONCLUSION We revealed the degree of importance and temporal pattern of the influence of several risk factors for nosocomial diarrhea, which could help clinicians manage nosocomial diarrhea.

Abstract
BACKGROUND The National Health Service in England advises hospitals collect data on hospital-onset diarrhoea (HOD). Contemporaneous data on HOD are lacking. AIM To investigate prevalence, aetiology and management of HOD on medical, surgical and elderly-care wards. METHODS A cross-sectional study in a volunteer sample of UK hospitals, which collected data on one winter and one summer day in 2016. Patients admitted ≥72 h were screened for HOD (definition: ≥2 episodes of Bristol Stool Type 5-7 the day before the study, with diarrhoea onset >48 h after admission). Data on HOD aetiology and management were collected prospectively. FINDINGS Data were collected on 141 wards in 32 hospitals (16 acute, 16 teaching). Point-prevalence of HOD was 4.5% (230/5142 patients; 95% confidence interval (CI) 3.9-5.0%). Teaching hospital HOD prevalence (5.9%, 95% CI 5.1-6.9%) was twice that of acute hospitals (2.8%, 95% CI 2.1-3.5%; odds ratio 2.2, 95% CI 1.7-3.0). At least one potential cause was identified in 222/230 patients (97%): 107 (47%) had a relevant underlying condition, 125 (54%) were taking antimicrobials, and 195 (85%) other medication known to cause diarrhoea. Nine of 75 tested patients were Clostridium difficile toxin positive (4%). Eighty (35%) patients had a documented medical assessment of diarrhoea. Documentation of HOD in medical notes correlated with testing for C. difficile (78% of those tested vs 38% not tested, P<0.001). One-hundred and forty-four (63%) patients were not isolated following diarrhoea onset. CONCLUSION HOD is a prevalent symptom affecting thousands of patients across the UK health system each day. Most patients had multiple potential causes of HOD, mainly iatrogenic, but only a third had medical assessment. Most were not tested for C. difficile and were not isolated.

Abstract
PURPOSE OF THE STUDY To determine the prevalence of delayed discharges of elderly inpatients and associated costs. DESIGN AND METHODS We searched Medline, Embase, Global Health, CAB Abstracts, Econlit, Web of Knowledge, EBSCO - CINAHL, The Cochrane Library, Health Management Information Consortium, and SCIE - Social Care Online for evidence published between 1990 and 2015 on number of days or proportion of delayed discharges for elderly inpatients in acute hospitals. Descriptive and regression analyses were conducted. Data on proportions of delayed discharges were pooled using a random effects logistic model and the association of relevant factors was assessed. Mean costs of delayed discharge were calculated in USD adjusted for Purchasing Power Parity (PPP). RESULTS Of 64 studies included, 52 (81.3%) reported delayed discharges as proportions of total hospital stay and 9 (14.1%) estimated the respective costs for these delays. Proportions of delayed discharges varied widely, from 1.6% to 91.3% with a weighted mean of 22.8%. This variation was also seen in studies from the same country, for example, in the United Kingdom, they ranged between 1.6% and 60.0%. No factor was found to be significantly associated with delays. The mean costs of delayed discharge also varied widely (between 142 and 31,935 USD PPP adjusted), reflecting the variability in mean days of delay per patient. IMPLICATIONS Delayed discharges occur in most countries and the associated costs are significant. However, the variability in prevalence of delayed discharges and available data on costs limit our knowledge of the full impact of delayed discharges. A standardization of methods is necessary to allow comparisons to be made, and additional studies are required-preferably by disease area-to determine the postdischarge needs of specific patient groups and the estimated costs of delays.

The 3-day rule for stool cultures: should all patients with haematological malignancies be excluded? Clin Microbiol Infect 2018; 24:1342.e1-1342.e3. [PMID: 30017969 DOI: 10.1016/j.cmi.2018.07.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2018] [Revised: 07/03/2018] [Accepted: 07/04/2018] [Indexed: 11/22/2022]
Abstract
OBJECTIVES The '3-day rule' for stool culture ordering suggests that only selected inpatients with nosocomial diarrhoea should have stool cultures for enteropathogenic bacteria (EPBs). Patients with haematological malignancies are not included in this group. We have analysed the ordering of stool cultures at Laikon Hospital to investigate whether all patients with haematological malignancies should be excluded from the 3-day rule. METHODS We have retrospectively analysed all inpatient stool specimens sent to the microbiology laboratory for enteropathogenic bacteria culture at Laikon Hospital, Athens, Greece, between January 1, 2014 and December 31, 2014. We classified stool cultures sent after the third day as 'appropriate', 'excluded' with standard rule, 'excluded' with haematological malignancies, and 'inappropriate'. RESULTS During the study period, 1101/1593 inpatient stool cultures (69.1%) had been ordered after the third day of hospitalization. The total yield for inpatient EPB stool cultures was 0.7% (11/1593). The yield for 'appropriate' cultures was significantly higher than the yield of all 'excluded' specimens (3.7% (3/81) versus 0.3% (2/585), p 0.018) and to 'inappropriate' orders (3.7% (3/81) versus 0.0% (0/485), p 0.0028). There was no difference in the yield between specimens 'excluded' with the standard rule and 'excluded' with haematological malignancies. CONCLUSIONS In our hospital, the yield of stool cultures from patients with haematological malignancies is similar to that of patients 'excluded' from the standard 3-day rule. If patients with haematological malignancies were not excluded from the rule, we would reduce the inpatient stool cultures by 13.6% (217/1593) at the cost of missing one positive stool culture.

Abstract
Diarrhea often occurs during enteral nutrition. Recently, several reports showed that diarrhea improves by adding egg yolk lecithin, an emulsifier, in an enteral formula. Therefore, we evaluated if this combination could improve diarrhea outcomes. We retrospectively investigated the inhibitory effects on watery stools by replacing a polymeric fomula with that containing egg yolk lecithin. Then, we investigated the emulsion stability in vitro. Next, we examined the lipid absorption using different emulsifiers among bile duct-ligated rats and assessed whether egg yolk lecithin, medium-chain triglyceride, and dietary fiber can improve diarrhea outcomes in a rat model of short bowel syndrome. Stool consistency or frequency improved on the day after using the aforementioned combination in 13/14 patients. Average particle size of the egg yolk lecithin emulsifier did not change by adding artificial gastric juice, whereas that of soy lecithin and synthetic emulsifiers increased. Serum triglyceride concentrations were significantly higher in the egg yolk lecithin group compared with the soybean lecithin and synthetic emulsifier groups in bile duct-ligated rats. In rats with short bowels, the fecal consistency was a significant looser the dietary fiber (+) group than the egg yolk lecithin (+) groups from day 6 of test meal feedings. The fecal consistency was also a significant looser the egg yolk lecithin (-) group than the egg yolk lecithin (+) groups from day 4 of test meal feeding. The fecal consistency was no significant difference between the medium-chain triglycerides (-) and egg yolk lecithin (+) groups. Enteral formula emulsified with egg yolk lecithin promotes lipid absorption by preventing the destruction of emulsified substances by gastric acid. This enteral formula improved diarrhea and should reduce the burden on patients and healthcare workers.

Abstract
BACKGROUND Clostridium difficile is an anaerobic, spore-forming and Gram-positive bacillus. It is the major cause of antibiotic-associated diarrhea prevailing in hospital settings. The morbidity and mortality of C. difficile infection (CDI) has increased significantly due to the emergence of hypervirulent strains. Because of the poor clinical different between CDI and other causes of hospital-acquired diarrhea, laboratory test for C. difficile is an important intervention for diagnosis of CDI. OBJECTIVE Laboratory tests for CDI can broadly detect either the organisms or its toxins. Currently, several laboratory tests are used for diagnosis of CDI, including toxigenic culture, glutamate dehydrogenase detection, nucleic acid amplification testing, cell cytotoxicity assay, and enzyme immunoassay towards toxin A and/or B. This review focuses on the rapid testing of C. difficile toxins and currently available methods for diagnosis of CDI, giving an overview of the role that the toxins rapid detecting plays in clinical diagnosis of CDI.

Cost-Effectiveness Analysis of Six Strategies to Treat Recurrent Clostridium difficile Infection. PLoS One 2016; 11:e0149521. [PMID: 26901316 PMCID: PMC4769325 DOI: 10.1371/journal.pone.0149521] [Citation(s) in RCA: 48] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2015] [Accepted: 02/02/2016] [Indexed: 12/17/2022] Open
Abstract
Objective To assess the cost-effectiveness of six treatment strategies for patients diagnosed with recurrent Clostridium difficile infection (CDI) in Canada: 1. oral metronidazole; 2. oral vancomycin; 3.oral fidaxomicin; 4. fecal transplantation by enema; 5. fecal transplantation by nasogastric tube; and 6. fecal transplantation by colonoscopy. Perspective Public insurer for all hospital and physician services. Setting Ontario, Canada. Methods A decision analytic model was used to model costs and lifetime health effects of each strategy for a typical patient experiencing up to three recurrences, over 18 weeks. Recurrence data and utilities were obtained from published sources. Cost data was obtained from published sources and hospitals in Toronto, Canada. The willingness-to-pay threshold was $50,000/QALY gained. Results Fecal transplantation by colonoscopy dominated all other strategies in the base case, as it was less costly and more effective than all alternatives. After accounting for uncertainty in all model parameters, there was an 87% probability that fecal transplantation by colonoscopy was the most beneficial strategy. If colonoscopy was not available, fecal transplantation by enema was cost-effective at $1,708 per QALY gained, compared to metronidazole. In addition, fecal transplantation by enema was the preferred strategy if the probability of recurrence following this strategy was below 8.7%. If fecal transplantation by any means was unavailable, fidaxomicin was cost-effective at an additional cost of $25,968 per QALY gained, compared to metronidazole. Conclusion Fecal transplantation by colonoscopy (or enema, if colonoscopy is unavailable) is cost-effective for treating recurrent CDI in Canada. Where fecal transplantation is not available, fidaxomicin is also cost-effective.

Abstract
UNLABELLED Delayed discharges represent an inefficient use of acute hospital beds. Social isolation and referral to a public-funded rehabilitation unit were significant predictors of delayed discharges while admission from an institution was a protective factor for older hip fracture patients. Preventing delays could save between 11.2 and 30.7 % of total hospital costs for this patient group. INTRODUCTION Delayed discharges of older patients from acute care hospitals are a major challenge for administrative, humanitarian, and economic reasons. At the same time, older people are particularly vulnerable to social isolation which has a detrimental effect on their health and well-being with cost implications for health and social care services. The purpose of the present study was to determine the impact and costs of social isolation on delayed hospital discharge. METHODS A prospective study of 278 consecutive patients aged 75 or older with hip fracture admitted, as an emergency, to the Orthopaedics Department of Hospital Universitário de Santa Maria, Portugal, was conducted. A logistic regression model was used to examine the impact of relevant covariates on delayed discharges, and a negative binomial regression model was used to examine the main drivers of days of delayed discharges. Costs of delayed discharges were estimated using unit costs from national databases. RESULTS Mean age at admission was 85.5 years and mean length of stay was 13.1 days per patient. Sixty-two (22.3 %) patients had delayed discharges, resulting in 419 bed days lost (11.5 % of the total length of stay). Being isolated or at a high risk of social isolation, measured with the Lubben social network scale, was significantly associated with delayed discharges (odds ratio (OR) 3.5) as was being referred to a public-funded rehabilitation unit (OR 7.6). These two variables also increased the number of days of delayed discharges (2.6 and 4.9 extra days, respectively, holding all else constant). Patients who were admitted from an institution were less likely to have delayed discharges (OR 0.2) with 5.5 fewer days of delay. Total costs of delayed discharges were between 11.2 and 30.7 % of total costs (€2352 and €9317 per patient with delayed discharge) conditional on whether waiting costs for placement in public-funded rehabilitation unit were included. CONCLUSION High risk of social isolation, social isolation and referral to public-funded rehabilitation units increase delays in patients' discharges from acute care hospitals.

Abstract
BACKGROUND The epidemiology of Clostridium difficile infection (CDI) has changed over the past decades with the emergence of highly virulent strains. The role of asymptomatic C. difficile colonization as part of the clinical spectrum of CDI is complex because many risk factors are common to both disease and asymptomatic states. In this article, we review the role of asymptomatic C. difficile colonization in the progression to symptomatic CDI, describe the epidemiology of asymptomatic C. difficile colonization, assess the effectiveness of screening and intensive infection control practices for patients at risk of asymptomatic C. difficile colonization, and discuss the implications for clinical practice. METHODS A narrative review was performed in PubMed for articles published from January 1980 to February 2015 using search terms 'Clostridium difficile' and 'colonization' or 'colonisation' or 'carriage'. RESULTS There is no clear definition for asymptomatic CDI and the terms carriage and colonization are often used interchangeably. The prevalence of asymptomatic C. difficile colonization varies depending on a number of host, pathogen, and environmental factors; current estimates of asymptomatic colonization may be underestimated as stool culture is not practical in a clinical setting. CONCLUSIONS Asymptomatic C. difficile colonization presents challenging concepts in the overall picture of this disease and its management. Individuals who are colonized by the organism may acquire protection from progression to disease, however they also have the potential to contribute to transmission in healthcare settings.

Abstract
Background Fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) are poorly absorbed, short-chain carbohydrates that play an important role in inducing functional gut symptoms. A low-FODMAP diet improves abdominal symptoms in patients with inflammatory bowel disease and irritable bowel syndrome. However, there were no study for the effect of FODMAP content on gastrointestinal intolerance and nutritional status in patients receiving enteral nutrition (EN). Methods In this randomized, multicenter, double-blind, 14-day clinical trial, eligible hospitalized patients receiving EN (n = 100) were randomly assigned to three groups; 84 patients completed the trial (low-FODMAP EN, n = 30; moderate-FODMAP EN, n = 28; high-FODMAP EN, n = 26). Anthropometric and biochemical parameters were measured; stool assessment was performed using the King’s Stool Chart and clinical definition. Results Baseline values were not significantly different among the three groups. After the 14-day intervention, diarrhea significantly improved in the low-FODMAP group than in the moderate- and high-FODMAP groups (P < 0.05). King’s Stool scores in diarrhea subjects were significantly and steadily reduced in the low-FODMAP group compared with the other two groups (P for time and EN type interaction <0.05). BMI increased significantly in the low- and high-FODMAP groups during the intervention (P < 0.05 for both), and showed a trend toward increasing in the moderate-FODMAP group (P < 0.10). Serum prealbumin increased significantly in all groups by 14-day; by 3-day, it had increased to the levels at 14-day in the low-FODMAP group. At 14-day, serum transferrin had increased significantly in the moderate-FODMAP group. In addition, subjects were classified by final condition (unimproved, normal maintenance, diarrhea only improved, constipation only improved, and recurrent diarrhea/constipation improved). Seventy-five percent of the diarrhea improved group consumed the low-FODMAP EN formula. 38.5 and 46.2 % of recurrent diarrhea/constipation improved group consumed the low- and moderate-FODMAP EN respectively. BMI significantly increased in all groups except the unimproved. Prealbumin levels significantly increased in the diarrhea-improved and recurrent diarrhea/constipation groups at 3-day and continued by 14-day, and in the constipation-improved group at 14-day. Transferrin levels significantly increased in the diarrhea-improved and recurrent diarrhea/constipation groups at 14-day. Conclusion Low-FODMAP EN may improve diarrhea, leading to improved nutritional status and facilitating prompt recovery from illness.

Enteral tube feeding of patients with acute stroke: when does the risk of diarrhoea increase? Intern Med J 2015; 44:1199-204. [PMID: 25228255 DOI: 10.1111/imj.12586] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2014] [Accepted: 09/02/2014] [Indexed: 11/27/2022]
Abstract
BACKGROUND/AIM We aimed to evaluate the relationship between the length of time acute stroke patients underwent enteral tube feeding (ETF) and episodes of diarrhoea, and to investigate the temporal cut-off point at which diarrhoea risk increases. METHODS An observational, retrospective study was conducted on patients with acute stroke admitted to a Stroke Centre. Patients undergoing ETF (ETF group) and those not undergoing ETF (control group) were analysed and matched by age and stroke severity. Data regarding demographic and clinical variables were recorded. The analysis was conducted using a receiver operating characteristic (ROC) curve and multivariate analyses. RESULTS A total of 130 inpatients was included (age 75.08 ± 11.53 years, 56.2% men). The ETF group had higher diarrhoea frequency (27.7% vs 6.2%, P = 0.001). The length of time on ETF was associated with diarrhoea development (odds ratio (OR), 1.12 increment per day; 95% confidence interval (CI) 1.05-1.18; P < 0.001), after adjusting for confounders. The ROC curve showed 7 days on ETF as a cut-off point for diarrhoea risk. Seven days or more on ETF was independently associated with diarrhoea (OR, 6.26; 95% CI 1.66-23.62; P = 0.007), whereas less than 7 days was not when compared with the control group (OR, 0.38; 95% CI 0.04-3.91; P = 0.413). CONCLUSIONS The length of time on ETF is associated with diarrhoea development in patients with acute stroke, demonstrating a temporal cut-off point. Seven days or longer on ETF is related to the occurrence of diarrhoea, whereas less than 7 days on ETF does not show this effect.

Abstract
BACKGROUND To meet the current recommendations for enteral tube feeding (ETF), we updated our previous practice in 2011 and began to use a 24-h delivery set hang time (DSHT). We evaluated the impact of this update on the risk of diarrhoea and in diarrhoea-free survival. METHODS Observational, retrospective study with historical controls on ischaemic and haemorrhagic stroke patients undergoing ETF. Diarrhoea occurrence (≥ 3 liquid stools in 24 h) was compared between patients with a 24 h DSHT (2011-2014) and a 72/96 h DSHT (2010-2011). The analysis was conducted using Kaplan-Meier curves and a Cox regression model. RESULTS A total of 175 patients were included [median age 81 years (IQR = 12), 46.9% males], 103 in the group with a 24 h DSHT and 72 in the group with a 72/96 h DSHT. The group with a 24 h DSHT had a lower diarrhoea frequency (13.6% vs. 34.7%, risk ratio: 0.39, 95% CI: 0.22-0.70, p = 0.001) and a lower diarrhoea incidence rate (0.87 vs. 2.32 cases of diarrhoea/100 patient*day, rate ratio: 0.37, 95% CI: 0.19-0.72, p = 0.004). The Kaplan-Meier curves showed a longer diarrhoea-free survival for this group (p = 0.003, log-rank test). A 24 h DSHT was associated with a lower risk of diarrhoea (HR = 0.27, 95% CI: 0.12-0.61, p = 0.002), adjusted by albumin, stroke severity, intravenous thrombolysis, the administration of clindamycin and cefotaxime, and the administration of an enteral formula for diabetic patients. CONCLUSIONS The 24 h DSHT was independently associated with a lower risk of diarrhoea and longer diarrhoea-free survival in hospitalised patients with acute stroke under ETF, compared with a 72/96 h DSHT.

Abstract
INTRODUCTION Aside from examination for Clostridium difficile, the yield of stool testing in hospital-onset diarrhea is poor. Clinical practice guidelines discourage overzealous stool testing in patients with diarrhea that develops after the third hospital day. However, the adoption of this recommendation into clinical practice is limited. Furthermore, the effect of microbiology laboratory improvements on hospital-onset diarrhea testing is largely unknown. METHODS A retrospective cohort study was conducted in a university-affiliated community-hospital and included all adult inpatients who developed diarrhea after hospitalization. RESULTS 132 adult patients (53% female) developed diarrhea after hospitalization in 2013. The cohort's mean age was 55.6 years. 46.2% of patients developed diarrhea in the first 3 days of hospitalization. Testing for parasites was negative in all examined 67 samples. Testing for C. difficile was positive in 13 cases (10.8%) out of 120 tested samples. Testing for other pathogens was positive in 1 sample (Campylobacter) out of 129 samples. Stool samples tested in the first 3 days of hospitalization were more likely to be positive (64.3 vs 35.7%, p = 0.1). Change in management was reported in 9 out of 14 patients (64.3%) with positive stool testing compared with 31 out of 118 patients (26.3%) with negative stool testing, p = 0.01. CONCLUSION Despite improvements in stool samples' testing, the yield continues to be low, especially in hospital-onset diarrhea past the third hospital day. Physicians' embracement of the '3-day rule' continues to be poor.

Abstract
Objective.To determine whether hydrogen peroxide vapor (HPV) decontamination can reduce environmental contamination with and nosocomial transmission of Clostridium difficile.Design.A prospective before-after intervention study.Setting.A hospital affected by an epidemic strain of C. difficile.Intervention.Intensive HPV decontamination of 5 high-incidence wards followed by hospital-wide decontamination of rooms vacated by patients with C. difficile-associated disease (CDAD). The preintervention period was June 2004 through March 2005, and the intervention period was June 2005 through March 2006.Results.Eleven (25.6%) of 43 cultures of samples collected by sponge from surfaces before HPV decontamination yielded C. difficile, compared with 0 of 37 cultures of samples obtained after HPV decontamination (P < .001). On 5 high-incidence wards, the incidence of nosocomial CDAD was significantly lower during the intervention period than during the preintervention period (1.28 vs 2.28 cases per 1,000 patient-days; P = .047). The hospital-wide CDAD incidence was lower during the intervention period than during the preintervention period (0.84 vs 1.36 cases per 1,000 patient-days; P = .26). In an analysis limited to months in which the epidemic strain was present during both the preintervention and the intervention periods, CDAD incidence was significandy lower during the intervention period than during the preintervention period (0.88 vs 1.89 cases per 1,000 patient-days; P = .047).Conclusions.HPV decontamination was efficacious in eradicating C. difficile from contaminated surfaces. Further studies of the impact of HPV decontamination on nosocomial transmission of C. difficile are warranted.

Abstract
During April 2007–April 2010, surveillance physicians in adult and pediatric medicine wards of three tertiary public hospitals in Bangladesh identified patients who developed hospital-acquired diarrhea. We calculated incidence of hospital-acquired diarrhea. To identify risk factors, we compared these patients to randomly selected patients from the same wards who were admitted > 72 hours without having diarrhea. The incidence of hospital-acquired diarrhea was 4.8 cases per 1,000 patient-days. Children < 1 year of age were more likely to develop hospital-acquired diarrhea than older children. The risk of developing hospital-acquired diarrhea increased for each additional day of hospitalization beyond 72 hours, whereas exposure to antibiotics within 72 hours of admission decreased the risk. There were three deaths among case-patients; all were infants. Patients, particularly young children, are at risk for hospital-acquired diarrhea and associated deaths in Bangladeshi hospitals. Further research to identify the responsible organisms and transmission routes could inform prevention strategies.

Abstract
Clostridium difficile is the most common cause of antibiotic-associated diarrhea, and it occasionally causes extraintestinal infections. We present a case of C. difficile-associated diarrhea that led to vertebral osteomyelitis associated with hardware. The osteomyelitis became symptomatic 2 years after the initial diarrheal event. C. difficile recovered from internal hardware sites cannot simply be regarded as a contaminant but should be treated.

Abstract
OBJECTIVE To provide a comprehensive review of the literature relating to Clostridium difficile (C. difficile) infection (CDI) in the pediatric population. METHODS Two investigators conducted independent searches of PubMed, Web of Science, and Scopus until March 31st, 2013. All databases were searched using the terms 'Clostridium difficile infection', 'Clostridium difficile associated diarrhea' 'antibiotic associated diarrhea', 'C. difficile', in combination with 'pediatric' and 'paediatric'. Articles which discussed pediatric CDI were reviewed and relevant cross references also read and evaluated for inclusion. Selection bias could be a possible limitation of this approach. FINDINGS There is strong evidence for an increased incidence of pediatric CDI. Increasingly, the infection is being acquired from the community, often without a preceding history of antibiotic use. The severity of the disease has remained unchanged. Several medical conditions may be associated with the development of pediatric CDI. Infection prevention and control with antimicrobial stewardship are of paramount importance. It is important to consider the age of the child while testing for CDI. Traditional therapy with metronidazole or vancomycin remains the mainstay of treatment. Newer antibiotics such as fidaxomicin appear promising especially for the treatment of recurrent infection. Conservative surgical options may be a life-saving measure in severe or fulminant cases. CONCLUSIONS Pediatric providers should be cognizant of the increased incidence of CDI in children. Early and judicious testing coupled with the timely institution of therapy will help to secure better outcomes for this disease.

Abstract
Clostridium difficile testing is shifting from toxin detection to C. difficile detection. Yet, up to 60% of patients with C. difficile by culture test negative for toxins and it is unclear whether they are infected or carriers. We reviewed medical records for 7046 inpatients with a C. difficile toxin test from 2005 to 2009 to determine the duration of diarrhea and rate of complications and mortality among toxin-positive (toxin+) and toxin- patients. Overall, toxin- patients had less severe diarrhea, fewer diarrhea days, and lower mortality (P < 0.001, all comparisons) than toxin+ patients. One toxin- patient (n = 1/6121; 0.02%) was diagnosed with pseudomembranous colitis, but there were no complications such as megacolon or colectomy for fulminant CDI among toxin- patients. These data suggest that C. difficile-attributable complications are rare among patients testing negative for C. difficile toxins. More studies are needed to evaluate the clinical significance of C. difficile detection in toxin- patients.

Abstract
Diarrhea is common among hospitalized patients but the causes are distinct from those of diarrhea in the community. We review existing data about the epidemiology of nosocomial diarrhea and summarize recent progress in understanding the mechanisms of diarrhea. Clinicians should recognize that most cases of nosocomial diarrhea have a noninfectious etiology, including medications, underlying illness, and enteral feeding. Apart from Clostridium difficile, the frequency of infectious causes such as norovirus and toxigenic strains of Clostridium perfringens, Klebsiella oxytoca, Staphylococcus aureus, and Bacteroides fragilis remains largely undefined and test availability is limited. Here we provide a practical approach to the evaluation and management of nosocomial diarrhea when tests for C. difficile are negative.

Abstract
BACKGROUND & AIMS In the past decade, there has been a growing epidemic of Clostridium difficile infection (CDI). During this time, use of proton pump inhibitors (PPIs) has increased exponentially. We evaluated the association between PPI therapy and the risk of CDI by performing a meta-analysis. METHODS We searched MEDLINE and 4 other databases for subject headings and text words related to CDI and PPI in articles published from 1990 to 2010. All observational studies that investigated the risk of CDI associated with PPI therapy and used CDI as an end point were considered eligible. Two investigators screened articles independently for inclusion criteria, data extraction, and quality assessment; disagreements were resolved based on consensus with a third investigator. Data were combined by means of a random-effects model and odds ratios were calculated. Subgroup and sensitivity analyses were performed based on study design and antibiotic use. RESULTS Thirty studies (25 case-control and 5 cohort) reported in 29 articles met the inclusion criteria (n = 202,965). PPI therapy increased the risk for CDI (odds ratio, 2.15, 95% confidence interval, 1.81-2.55), but there was significant heterogeneity in results among studies (P < .00001). This association remained after subgroup and sensitivity analyses, although significant heterogeneity persisted among studies. CONCLUSIONS PPI therapy is associated with a 2-fold increase in risk for CDI. Because of the observational nature of the analyzed studies, we were not able to study the causes of this association. Further studies are needed to determine the mechanisms by which PPI therapy might increase risk for CDI.

Abstract
The rising incidence of Clostridium difficile (C. difficile) infection or CDI is now a problem of pandemic proportions. The NAP1 hypervirulent strain of C. difficile is responsible for a majority of recent epidemics and the widespread use of fluoroquinolone antibiotics may have facilitated the selective proliferation of this strain. The NAP1 strain also is more likely to cause severe and fulminant colitis characterized by marked leukocytosis, renal failure, hemodynamic instability, and toxic megacolon. No single test suffices to diagnose severe CDI, instead; the clinician must rely on a combination of clinical acumen, laboratory testing, and radiologic and endoscopic modalities. Although oral vancomycin and metronidazole are considered standard therapies in the medical management of CDI, recently it has been demonstrated that vancomycin is the more effective antibiotic in cases of severe disease. Moreover, early surgical consultation is necessary in patients who do not respond to medical therapy or who demonstrate rising white blood cell counts or hemodynamic instability indicative of fulminant colitis. Subtotal colectomy with end ileostomy is the procedure of choice for fulminant colitis. When applied to select patients in a judicious and timely fashion, surgery can be a life-saving intervention. In addition to these therapeutic approaches, several investigational treatments including novel antibiotics, fecal bacteriotherapy and immunotherapy have shown promise in the care of patients with severe CDI.

Infection prevention and control practices related to Clostridium difficile infection in Canadian acute and long-term care institutions. Am J Infect Control 2011; 39:177-82. [PMID: 21458680 DOI: 10.1016/j.ajic.2011.01.007] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2010] [Revised: 01/12/2011] [Accepted: 01/20/2011] [Indexed: 11/21/2022]
Abstract
BACKGROUND Clostridium difficile is an important pathogen in Canadian health care facilities, and infection prevention and control (IPC) practices are crucial to reducing C difficile infections (CDIs). We performed a cross-sectional study to identify CDI-related IPC practices in Canadian health care facilities. METHODS A survey assessing facility characteristics, CDI testing strategies, CDI contact precautions, and antimicrobial stewardship programs was sent to Canadian health care facilities in February 2005. RESULTS Responses were received from 943 (33%) facilities. Acute care facilities were more likely than long-term care (P < .001) and mixed care facilities (P = .03) to submit liquid stools from all patients for CDI testing. Physician orders were required before testing for CDI in 394 long-term care facilities (66%)-significantly higher than the proportions in acute care (41%; P < .001) and mixed care sites (49%; P < .001). A total of 841 sites (93%) had an infection control manual, 639 (76%) of which contained CDI-specific guidelines. Antimicrobial stewardship programs were reported by 40 (29%) acute care facilities; 19 (54%) of these sites reported full enforcement of the program. CONCLUSION Canadian health care facilities have widely varying C difficile IPC practices. Opportunities exist for facilities to take a more active role in IPC policy development and implementation, as well as antimicrobial stewardship.

Abstract
Hospital acquired or nosocomial diarrhea affects up to one third of hospitalized patients. It increases mortality rates as well as length and costs of the hospital stay. Drug side effects are the predominant cause of nosocomial diarrhea whilst clostridium difficile is the most common infectious agent, whose development is closely linked to antibiotic usage. The causal therapy of mild clostridium difficile infections is controversially discussed. Nevertheless, the use of Metronidazol for mild cases and of vancomycin for severe forms of the disease is recommended. Diarrhea outbreaks might be caused by viruses and less often by Salmonella and Listeria. Norovirus infections are of outstanding importance. Rehydration and isolation to prevent the spread of this highly contagious virus are the only reasonable options as we still lack a proper therapy.

Abstract
INTRODUCTION Clostridium difficile-associated diarrhoea (CDAD) is the most common cause of nosocomial diarrhoea in the USA. In this study, we sought to determine the association between chronic kidney disease (CKD) and CDAD. METHODS A case-control study was designed to determine the association between CKD and CDAD in an urban hospital. Over a 2-year period, all patients diagnosed with CDAD (n = 188) were included as cases and the prevalence of CKD was calculated. Age- and sex-matched patients without CDAD were considered as controls with a ratio of 2:1 controls to cases. The prevalence of different stages of advanced CKD (stages 3-5) was determined and compared between groups. Also the calculated odds ratios (OR) were adjusted for multiple possible confounding variables using logistic regression analysis. RESULTS There was no significant difference in prevalence of advanced CKD between cases and controls (OR = 1.38, 95% confidence intervals (CI) = 0.90-2.12, P = 0.1365). The association between CKD and CDAD remained insignificant in subjects with CKD stages 3-5 who were not on dialysis (OR = 1.07, 95% CI = 0.65-1.77), P = 0.7970). However, the group with end-stage renal disease on dialysis showed a significant association (OR = 2.60, 95% CI = 1.25-5.41, P = 0.0165). Controlling for antibiotics as a possible confounding variable, yielded an OR that was not statistically significant (OR = 2.05, 95% CI = 0.94-4.47, P = 0.07), but still showing a trend towards increased risk. CONCLUSION End-stage renal disease may increase the risk of acquiring CDAD through unknown mechanisms. This suggests implementing better surveillance strategies for these patients and eliminating the known risk factors for CDAD.

Abstract
We conducted a prospective study to evaluate the prevalence and epidemiology of CDI in Kuwait government hospitals over a 3-year period, January 2003 to December 2005, to determine the ribotypes responsible for CDI and to estimate the prevalence of ribotype 027. We also conducted a case-control study to identify the risk factors in our patient population. A total of 697 stool samples from patients with suspected CDI were obtained and sent to Anaerobe Reference Laboratory, Faculty of Medicine, Kuwait University for Clostridium difficile toxin detection, culture and PCR ribotyping. During the period, 73 (10.5%) out of 697 patients met the case definition of CDI. Of these, 56 (76.7%) were hospital-acquired and 17 (23.3%) were from outpatient clinics. Thus, the prevalence of hospital-acquired CDI amongst patients with diarrhoea was 8% over the study period; the prevalence in 2003, 2004 and 2005 was 9.7%, 7.8% and 7.2%, respectively. Our data showed that 42.9% of the CDI patients were above 60 years, of which >79% were aged 71 years and above. Patients with CDI were more likely than the controls to have been exposed to immunosuppressive drugs and feeding via nasogastric tube. The most common ribotypes isolated during this study were 002, 001, 126 and 140 and they represent 55.1% of all isolates. PCR ribotype 027 was not isolated.

Abstract
GOALS To examine if intake of Lactobacillus plantarum can prevent gastrointestinal side effects in antibiotic-treated patients. BACKGROUND Diarrhea is a common side effect of treatment with antibiotics. Some studies indicate that the risk of antibiotic-associated diarrhea can be reduced by administration of certain probiotic microorganisms. STUDY Patients treated for infections at a university hospital infectious diseases clinic were randomized to daily intake of either a fruit drink with L. plantarum 299v (10(10) colony forming units/d) or a placebo drink, until a week after termination of antibiotic treatment. Subjects recorded the number and consistency of stools as well as gastrointestinal symptoms until up to 3 weeks after last intake of test drink. Fecal samples were collected before the first intake of test drink and after termination of antibiotic therapy and analyzed for Clostridium difficile toxin. RESULTS Clinical characteristics on admission were similar in the 2 groups. The overall risk of developing loose or watery stools was significantly lower among those receiving L. plantarum [odds ratio (OR), 0.69; 95% confidence interval (CI), 0.52-0.92; P=0.012], as was development of nausea (OR, 0.51; 95% CI, 0.30-0.85; P=0.0097). Diarrhea defined as > or =3 loose stools/24 h for > or =2 consecutive days was unaffected by the treatment (OR, 1.4; 95% CI, 0.33-6.0; P=0.86). No significant differences regarding carriage of toxin producing C. difficile were observed between the groups. CONCLUSIONS Our results indicate that intake of L. plantarum could have a preventive effect on milder gastrointestinal symptoms during treatment with antibiotics.

Abstract
AIM While the incidence of Clostridium difficile-associated diarrhoea (CDAD) has increased sharply over the last 15 years, its risk factors are still not well defined. The aim of this study was to review cases of CDAD at the major teaching hospital in Tasmania, Australia, to identify risk factors for CDAD and their association with prognosis. METHODS A retrospective review of the medical records of adult patients admitted to the hospital between January 1994 and December 1996 was performed. Sixty-four patients who developed CDAD prior to or during their admission, and an additional 120 diarrhoea-free patients (the control group) were studied. An extensive range of demographic and clinical variables were recorded, and the differences between the control group and patients with CDAD were evaluated. RESULTS The CDAD patients had a median age of 66 years (range 22-95 years), with females accounting for 52% of cases. There were no significant demographic differences from the control group. Identifiable risk factors for developing CDAD were severe underlying disease, renal impairment, exposure to antibiotics or antineoplastic agents, and the use of total parenteral nutrition or nasogastric feeding. Cephalosporins were the most frequently used antibiotics in both CDAD and control patients, with cefotaxime being the only antibiotic which was identified as being significantly associated with an increased risk of CDAD. The median length of diarrhoea episodes was 9 days (range 1-60 days). The mortality rate was 17.2%, and factors associated with a poor prognosis were older age, severe underlying disease, renal impairment and failure to treat with metronidazole or vancomycin. Delay in starting specific treatment and use of codeine were related to prolonged CDAD. CONCLUSION CDAD is a growing contributor to hospital morbidity and costs. Severely ill patients with compromised immune function are particularly susceptible, with antibiotic use being a major risk factor. Prompt diagnosis and initiation of treatment are important factors in the improvement of prognosis.

Abstract
BACKGROUND We carried out a survey to identify the infection prevention and control practices in place in Canadian hospitals participating in the Canadian Nosocomial Infection Surveillance Program (CNISP). METHODS An infection prevention and control practices survey was sent to CNISP hospitals at the beginning of November 2004, the same time that CNISP started a 6-month prospective surveillance for Clostridium difficile infection (CDI) to evaluate their infection prevention and control measures and laboratory methods for C difficile. RESULTS A total of 33 hospitals completed and returned the survey. Infection control precautions were initiated in 18 hospitals (55%) due to the presence of a symptomatic patient before the C difficile laboratory tests were available. All of the hospitals used gloves and gowns as additional precautions. Twenty-three hospitals (70%) tested liquid stools based on a clinician's order, and 8 (24%) tested all liquid stools submitted whether of not C difficile testing was requested. The hospitals used 1 of 3 different products as a standard hospital-wide disinfectant; 24 (73%) used a quaternary ammonium compound, 8 (24%) used accelerated hydrogen peroxide, and 1 (3%) used a hypochlorite solution (1:10 bleach solution). CONCLUSION Although the hospitals used contact precautions quite uniformly, considerable variation was seen among hospitals in terms of testing strategies, cleaning and disinfection protocols and products, and isolation practices. The timing for the initiation of infection control precautions is important to prevent secondary transmission of CDI. Most of the hospitals implemented precautions while waiting for the toxin assay results.

Abstract
OPT-80, a novel, minimally absorbed macrocycle, is a candidate treatment option for Clostridium difficile infection (CDI) based on cure without recurrence of CDI in the hamster challenge model, good in vitro activity against C. difficile, and relative sparing of commensal gram-negative anaerobes. In this open-label, dose-ranging clinical trial, 48 evaluable subjects were randomized to receive either 50, 100, or 200 mg of OPT-80 orally every 12 h for 10 days as treatment for mild to moderately severe CDI. OPT-80 was well tolerated by all subjects. Plasma concentrations were below the lower limit of quantitation in almost one-half of patients and typically <or=20 ng/ml across the dose range; the mean fecal concentrations exceeded the MIC at which 90% of the isolates tested are inhibited by 2,000- to 10,000-fold with increasing dosages. Resolution of diarrhea within 10 days was achieved in 10/14 patients (71%), 12/15 patients (80%), and 15/16 patients (94%), and the median time to resolution of diarrhea was reduced from 5.5 to 3.0 days with increasing dosages. Across all groups, the clinical cure rate, which was defined as resolution of diarrheal disease without the need for further treatment, was 41/45 patients (91%). Recurrence of CDI at approximately 1 month after treatment was observed in two (5%) patients, one each in the 100-mg and 400-mg groups. The apparent high clinical response, good tolerance, low recurrence rate, and more-complete and rapid symptom control with the highest dosage support the selection of the 200-mg twice-daily dose for further clinical development of OPT-80 for treatment of CDI.

Abstract
Infectious diarrhea is an important public health problem worldwide. Research has provided new insights into the mechanisms of diarrhea caused by various pathogens that are classified as noninflammatory, inflammatory or invasive. These three groups of organisms cause two diarrheal syndromes--noninflammatory diarrhea and inflammatory diarrhea. The noninflammatory diarrheas are caused by enterotoxin-producing organisms such as Vibrio cholerae and enterotoxigenic Escherichia coli, or by viruses that adhere to the mucosa and disrupt the absorptive and/or secretory processes of the enterocyte without causing acute inflammation or mucosal destruction. Inflammatory diarrhea is caused by two groups of organisms--cytotoxin-producing, noninvasive bacteria (e.g. enteroaggregative Escherichia coli, enterohemorrhagic Escherichia coli and Clostridium difficile), or by invasive organisms (e.g. Salmonella spp., Shigella spp., Campylobacter spp., Entamoeba histolytica). The cytotoxin-producing organisms adhere to the mucosa, activate cytokines and stimulate the intestinal mucosa to release inflammatory mediators. Invasive organisms, which can also produce cytotoxins, invade the intestinal mucosa to induce an acute inflammatory reaction, involving the activation of cytokines and inflammatory mediators. Regardless of the underlying mechanism they use, these various types of pathogen have all successfully evolved to evade and modulate the host defense systems. The mechanisms by which the different pathogens invade the host and cause infectious diarrhea are the topic of this Review.

Abstract
RACIONAL: Diarréia nosocomial parece ser comum em unidades de terapia intensiva, embora sua epidemiologia seja pouco documentada em nosso meio. OBJETIVO: Determinar a incidência e fatores de risco de diarréia entre pacientes adultos internados em unidade de terapia intensiva. MÉTODOS: Foram incluídos prospectivamente 457 pacientes no período entre outubro de 2005 e outubro de 2006. Dados demográficos, clínicos e bioquímicos, bem como aspecto e número de evacuações eram registrados diariamente até a saída do paciente do setor. RESULTADOS: Diarréia ocorreu em 135 (29,5%) pacientes, durando em média 5,4 dias. O tempo do seu início em relação à internação foi de 17,8 dias e casos similares de diarréia no mesmo período foram registrados em 113 (83,7%) pacientes. A mortalidade hospitalar foi maior nos pacientes com diarréia do que naqueles sem esta intercorrência. Na análise multivariada através de modelo de regressão logística, apenas o número de antibióticos (OR 1,65; IC 95% = 1,39-1,95) e o número de dias de antibioticoterapia (OR 1,16; IC 95% = 1,12-1,20) associaram-se estatisticamente com a ocorrência de diarréia. Cada dia de acréscimo a mais da antibioticoterapia aumentou em 16% o risco de diarréia (IC 12% a 20%), enquanto a adição de um antibiótico a mais ao esquema antimicrobiano aumentou as chances de ocorrência de diarréia em 65% (IC 39% a 95%). CONCLUSÃO: A incidência de diarréia nosocomial na unidade de terapia intensiva é elevada (29,5%). Os principais fatores de risco para sua ocorrência foram número de antibióticos prescritos e duração da antibioticoterapia. Além das precauções entéricas, a prescrição judiciosa e limitada de antimicrobianos, provavelmente reduzirá a ocorrência de diarréia neste setor.

[PMID: 18417321 DOI: 10.1016/j.nut.2008.02.004] [Citation(s) in RCA: 31] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2007] [Revised: 01/25/2008] [Accepted: 02/02/2008] [Indexed: 12/13/2022]
Abstract
OBJECTIVE This study examined the risk of diarrhea as a result of providing enteral nutrition in the hospital setting, adjusting for other clinical and therapeutic factors. METHODS Adults admitted to a general tertiary care university hospital, in clinical or surgical units, were enrolled in the study between June 2004 and May 2005 and prospectively followed during their hospital stay. For each patient treated with enteral nutrition (n = 302), a comparable non-treated patient from the same ward (who also received antibiotics previously) and was similarly cared for by the same hospital staff was included in the study (n = 302), constituting a double-cohort study. All patients were seen three times per week, on alternating days, until the occurrence of diarrhea or hospital discharge. Cox's regression analyses were applied for adjustments. RESULTS The incidence of diarrhea was 18% for patients receiving enteral nutrition and 6% for non-treated patients (P < 0.01). In multivariate analyses, enteral nutrition was independently associated with diarrhea (hazard ratio 2.7, 95% confidence interval 1.6-4.7), even adjusting for age (hazard ratio 1.02, 95% confidence interval 1.00-1.03) and hospitalization during the summer months (hazard ratio 2.4, 95% confidence interval 1.5-3.9). Patients for whom strict adherence to delivery-set washing-and-changing procedures was observed (on >75% of days) presented a lower incidence of diarrhea (6.5% versus 20.3%, P = 0.02; and 5.9% versus 19.8%, P = 0.05, respectively). CONCLUSION Providing enteral nutrition to the hospitalized elderly during the summer months is associated with a higher risk of diarrhea. Strategies aimed toward improvement in the quality of enteral nutrition practices should be evaluated to minimize this deleterious clinical outcome.

Abstract
Current therapies for Clostridium difficile infection (CDI) are encumbered by treatment failures and recurrences. Due to its high in vitro activity against C. difficile but low activity against the typical intestinal flora, minimal absorption, and durable cure in the hamster model of C. difficile infection, OPT-80 was considered for clinical development as a therapy for CDI. This trial consisted of two phases. Four single oral doses of OPT-80 (100, 200, 300, and 450 mg) were administered in a crossover manner to 16 healthy volunteers in a double-blind, placebo-controlled phase 1A study; a 1- to 2-week washout interval separated the treatments. In the double-blind phase 1B study, 24 healthy subjects were randomized to receive OPT-80 (150, 300, or 450 mg) or placebo for 10 days. In both studies, OPT-80's safety and tolerability were evaluated and the concentrations of OPT-80 and its primary metabolite (OP-1118) in plasma and feces were determined. OPT-80 levels in the urine were also analyzed for the phase 1A study. In both the single-dose and the multiple-dose studies, OPT-80 was well tolerated by all subjects in all dose groups. Maximal plasma concentrations were near or below the limit of quantification (5 ng/ml) across the dose range; urine concentrations were below the detection limit. The fecal total recovery of OPT-80 plus its major metabolite, OP-1118, approximated 100%. The tolerability, high fecal concentration, and low systemic exposure data from these studies support the further clinical development of OPT-80 as an oral therapy for CDI.

Abstract
BACKGROUND One of the side effects of antimicrobial therapy is a disturbance of the intestinal microbiota potentially resulting in antibiotic-associated diarrhea (AAD). In this placebo-controlled double-blind study, the effect of a multispecies probiotic on the composition and metabolic activity of the intestinal microbiota and bowel habits was studied in healthy volunteers taking amoxycillin. METHODS Forty-one healthy volunteers were given 500 mg amoxycillin twice daily for 7 days and were randomized to either 5 g of a multispecies probiotic, Ecologic AAD (10(9) cfu/g), or placebo, twice daily for 14 days. Feces and questionnaires were collected on day 0, 7, 14, and 63. Feces was analyzed as to the composition of the intestinal microbiota, and beta-glucosidase activity, endotoxin concentration, Clostridium difficile toxin A, short chain fatty acids (SCFAs), and pH were determined. Bowel movements were scored according to the Bristol stool form scale. RESULTS Mean number of enterococci increased significantly from log 4.1 at day 0 to log 5.8 (day 7) and log 6.9 (day 14) cfu/g feces (P < 0.05) during probiotic intake. Although no other significant differences were observed between both intervention groups, within each group significant changes were found over time in both microbial composition and metabolic activity. Moreover, bowel movements with a frequency >or=3 per day for at least 2 days and/or a consistency >or=5 for at least 2 days were reported less frequently in the probiotic compared to the placebo group (48%vs 79%, P < 0.05). CONCLUSIONS Apart from an increase in enterococci no significant differences in microbial composition and metabolic activity were observed in the probiotic compared with the placebo group. However, changes over time were present in both groups, which differed significantly between the probiotic and the placebo arm, suggesting that the amoxycillin effect was modulated by probiotic intake. Moreover, the intake of a multispecies probiotic significantly reduced diarrhea-like bowel movements in healthy volunteers receiving amoxycillin.

Abstract
AIM: To assess the incidence and analyze the risk factors for Clostridium difficile-associated diarrhea (CDAD) after living donor liver transplantation (LDLT) in adult.
METHODS: The micobiological data and medical records of 242 adult recipients that underwent LDLT at the Tokyo University Hospital were analyzed retrospectively. The independent risk factors for postoperative CDAD were identified.
RESULTS: Postoperative CDAD occurred in 11 (5%) patients. Median onset of CDAD was postoperative d 19 (range, 5-54). In the multivariate analyses, male gender (odds ratio, 4.56) and serum creatinine (≥ 1.5 mg/dL, odds ratio, 16.0) independently predicted postoperative CDAD.
CONCLUSION: CDAD should be considered in the differential diagnosis of patients with postoperative diarrhea after LDLT.

Abstract
We prospectively studied the comparative epidemiology and risk factors for Clostridium difficile, Clostridium perfringens, and Staphylococcus aureus antibiotic-associated diarrhea (AAD). Four thousand six hundred fifty-nine inpatient fecal specimens (11 months) were tested for C. difficile cytotoxin, C. perfringens enterotoxin, and S. aureus by Vero cell assay, enzyme-linked immunosorbent assay, and growth on fresh blood agar, respectively. Two distinct age-, sex-, and location-matched control patient groups were used for multivariate logistic regression risk factor analyses: symptomatic patients who were AAD pathogen negative and asymptomatic patients with histories of recent antimicrobial therapy. All AAD pathogen isolates were DNA fingerprinted. In AAD cases, the prevalences of C. difficile cytotoxin, C. perfringens enterotoxin, and S. aureus were 12.7%, 3.3%, and 0.2%, respectively (15.8% overall). Age of >70 years was a common risk factor. Other risk factors for infective AAD and C. difficile AAD included length of hospital stay and use of feeding tubes (length of stay odds ratios [OR], 1.017 and 1.012; feeding tube OR, 1.864 and 2.808). Female gender and use of antacids were significantly associated with increased risk of C. perfringens AAD (OR, 2.08 and 2.789, respectively), but unlike what was found for C. difficile AAD, specific antibiotic classes were not associated with increased risk. A limited number of genotypes caused the majority of C. difficile and C. perfringens AAD cases. Similar to what was found for C. difficile AAD, there was epidemiological evidence of C. perfringens AAD case clustering and reinfection due to different strains. C. difficile AAD was approximately 4 and 60 times more common than C. perfringens AAD and S. aureus AAD, respectively. Risk factors for these AAD pathogens differed, highlighting the need to define specific control measures. There is evidence of nosocomial transmission in cases of C. perfringens AAD.
