Abstract
Identifying and distinguishing dormant and active bacterial spores are vital for biosecurity, food safety, and space exploration. Yet, there is a lack of simple, quick, and nondestructive methods to achieve this. The common Schaeffer-Fulton method is both sample-destructive and requires significant operator involvement. In this study, we employed lanthanide-beta-diketonate complexes to directly observe both dormant and germinated single spores. Staining is instantaneous and requires minimal sample processing. The complex stains areas outside the core of dormant spores, leaving the core hollow and nonfluorescent. However, upon germination, the complex enters the core, making it brightly fluorescent. This difference was noted in five bacterial species including Bacillus, Clostridium, and Clostridioides. Various lanthanides and beta-diketonates can be mixed to form a range of spore-visualizing complexes. Due to their low toxicity, these complexes allow for live imaging of single germinating spores. We demonstrate low-cost imaging using a USB microscope as well as imaging of spores in milk matrices. This method provides a valuable tool for studying bacterial spores.

J Hosp Infect 2023; 139:106-112. [PMID: 37451405 DOI: 10.1016/j.jhin.2023.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 07/07/2023] [Accepted: 07/07/2023] [Indexed: 07/18/2023]
Abstract
BACKGROUND Despite the growing clinical and economic burden of Clostridioides difficile infection (CDI), data on CDI in the intensive care unit (ICU) in the Asia-Pacific region are lacking. METHODS This retrospective study analysed 191 patients who were treated with CDI in the ICUs of three hospitals in South Korea from January 2017 to May 2021. Backward-stepwise multiple logistic regression was used to identify factors influencing the treatment response and mortality. RESULTS Fifty-eight patients (30.4%) were considered immunocompromised. The mean Charlson comorbidity index was 5.65 ± 2.39 (10-year survival rate: 21%), the APACHE II score was 20.86 ± 7.78 (mortality rate: 40%), the ATLAS score was 5.45 ± 1.59 (cure rate: 75%), and the SOFA score was 7.97 ± 4.03 (mortality rate: 21.5%). Fifty-eight (30.4%) of the CDI cases were severe and 40 (20.9%) were fulminant. Oral vancomycin or oral metronidazole was the most frequently first-line treatments (N = 57; 32.6%). The 10-day response rate was 59.7% and the eight-week overall mortality rate was 41.4%. Fulminant CDI (OR 0.230; 95% CI 0.085-0.623) and each one-unit increment in the SOFA score (OR 0.848; 95% CI 0.759-0.947) were associated with treatment failure. High APACHE II (OR 0.355; 95% CI 0.143-0.880) and SOFA (OR 0.164; 95% CI 0.061-0.441) scores were associated with higher mortality. CONCLUSIONS High-risk patients in the ICU had a higher mortality rate and a lower cure rate of CDI. Further research is required to provide more accurate prediction scoring systems and better clinical outcomes.

Association between epidemiologic case definition categories and adverse clinical outcome in patients with Clostridiodes difficile infection in San Francisco County, California: a five-year retrospective cohort study.

Abstract
BACKGROUND Understanding the predictors of adverse clinical outcomes following incident Clostridiodes difficile infection (CDI) can help clinicians identify which patients are at risk of complications and help prioritize the provision of their care. In this study, we assessed the associations between epidemiologic case definition categories and adverse clinical outcomes in patients with CDI in San Francisco County, California. METHODS We conducted a retrospective cohort study using CDI surveillance data (n = 3274) from the California Emerging Infections Program for the time period 2016 to 2020. After independent associations were established, two multivariable logistic and log-binomial regression models were constructed for the final statistical analysis. RESULT The mean cumulative incidence of CDI cases was 78.8 cases per 100,000 population. The overall recurrence rate and the 30-day all-cause mortality rate were 11.1% and 4.5%, respectively. After adjusting for potential confounders, compared to the community associated CDI cases, healthcare facility onset (AOR = 3.1; 95% CI [1.3-7]) and community-onset-healthcare facility associated (AOR = 2.4; 95% CI [1.4-4.3]) CDI cases were found to have higher odds of all-cause 30-day mortality. Community onset-healthcare facility-associated CDI case definition category was found to be significantly associated with an increased risk of recurrence of CDI (ARR = 1.7; 95% CI [1.2-2.4]). CONCLUSION Although the incidence of community-associated CDI cases has been rising, the odds of all-cause 30-day mortality and the risk of recurrent CDI associated with these infections are lower than healthcare facility onset and community-onset healthcare facility-associated CDI cases.

Abstract
Clostridioides difficile is an obligate anaerobic pathogen among the most common causes of healthcare-associated infections. It poses a global threat due to the clinical outcomes of infection and resistance to antibiotics recommended by international guidelines for its eradication. In particular, C. difficile infection can lead to fulminant colitis associated with shock, hypotension, megacolon, and, in severe cases, death. It is therefore of the utmost urgency to fully characterize this pathogen and better understand its spread, in order to reduce infection rates and improve therapy success. This review aims to provide a state-of-the-art overview of the genetic variation of C. difficile, with particular regard to pathogenic genes and the correlation with clinical issues of its infection. We also summarize the current typing techniques and, based on them, the global distribution of the most common ribotypes. Finally, we discuss genomic surveillance actions and new genetic engineering strategies as future perspectives to make it less difficile.

Early Prognostic Stratification of Clostridioides difficile Infection in the Emergency Department: The Role of Age and Comorbidities. J Pers Med 2022; 12:jpm12101573.

Abstract
Clostridioides difficile infection (CDI) represents a significant cause of morbidity and mortality, mainly in older and frail subjects. Early identification of outcome predictors, starting from emergency department (ED) admission, could help to improve their management. In a retrospective single-center study on patients accessing the ED for diarrhea and hospitalized with a diagnosis of CDI infection, the patients’ clinical history, presenting symptoms, vital signs, and laboratory exams at ED admission were recorded. Quick sequential organ failure assessments (qSOFA) were conducted and Charlson’s comorbidity indices (CCI) were calculated. The primary outcomes were represented by all-cause in-hospital death and the occurrence of major cumulative complications. Univariate and multivariate Cox regression analyses were performed to establish predictive risk factors for poor outcomes. Out of 450 patients, aged > 81 years, dyspnea at ED admission, creatinine > 2.5 mg/dL, white blood cell count > 13.31 × 109/L, and albumin < 30 µmol/L were independently associated with in-hospital death and major complications (except for low albumin). Both in-hospital death and major complications were not associated with multimorbidity. In patients with CDI, the risk of in-hospital death and major complications could be effectively predicted upon ED admission. Patients in their 8th decade have an increased risk independent of comorbidities.

Abstract
The human gut microbiota consists of bacteria, archaea, fungi, and viruses. It is a dynamic ecosystem shaped by several factors that play an essential role in both healthy and diseased states of humans. A disturbance of the gut microbiota, also termed "dysbiosis", is associated with increased host susceptibility to a range of diseases. Because of splanchnic ischemia, exposure to antibiotics, and/or the underlying disease, critically ill patients loose 90% of the commensal organisms in their gut within hours after the insult. This is followed by a rapid overgrowth of potentially pathogenic and pro-inflammatory bacteria that alter metabolic, immune, and even neurocognitive functions and that turn the gut into the driver of systemic inflammation and multiorgan failure. Indeed, restoring healthy microbiota by means of fecal microbiota transplantation (FMT) in the critically ill is an attractive and plausible concept in intensive care. Nonetheless, available data from controlled studies are limited to probiotics and FMT for severe C. difficile infection or severe inflammatory bowel disease. Case series and observational trials have generated hypotheses that FMT might be feasible and safe in immunocompromised patients, refractory sepsis, or severe antibiotic-associated diarrhea in ICU. There is a burning need to test these hypotheses in randomized controlled trials powered for the determination of patient-centered outcomes.

Abstract
PURPOSE OF REVIEW The purpose of the review is to provide all the recent data focusing on the diagnostic and treatment of Clostridioides difficile infection in patients admitted in the ICU. RECENT FINDINGS In the ICU, diagnosis remains complicated with a large number of alternative diagnosis. The treatment classically relies on vancomycin but fidaxomicin and fecal microbiota transplantation are now potential solutions in selected indications. SUMMARY Data on ICU-related CDI remain limited and conflicting. To date, there is no unique and simple way to obtain a diagnosis for CDI, the combination of clinical signs and a two-step testing algorithm remains the recommended gold-standard. Two molecules can be proposed for first line treatment: vancomycin and fidaxomicin. Although metronidazole may still be discussed as a treatment option for mild CDI in low-risk patients, its use for ICU-patients does not seem reasonable. Several reports suggest that fecal microbiota transplantation could be discussed, as it is well tolerated and associated with a high rate of clinical cure. CDI is a dynamic and active area of research with new diagnostic techniques, molecules, and management concepts likely changing our approach to this old disease in the near future.

Abstract
OBJECTIVES To review published clinical evidence on management of Clostridioides difficile infection in critically ill patients. DATA SOURCES We obtained relevant studies from a PubMed literature review and bibliographies of reviewed articles. STUDY SELECTION We selected English-language studies addressing aspects of C. difficile infection relevant to critical care clinicians including epidemiology, risk factors, diagnosis, treatment, and prevention, with a focus on high-quality clinical evidence. DATA EXTRACTION We reviewed potentially relevant studies and abstracted information on study design, methods, patient selection, and results of relevant studies. This is a synthetic (i.e., not systematic) review. DATA SYNTHESIS C. difficile infection is the most common healthcare-associated infection in the United States. Antibiotics are the most significant C. difficile infection risk factor, and among antibiotics, cephalosporins, clindamycin, carbapenems, fluoroquinolones, and piperacillin-tazobactam confer the highest risk. Age, diabetes mellitus, inflammatory bowel disease, and end-stage renal disease are risk factors for C. difficile infection development and mortality. C. difficile infection diagnosis is based on testing appropriately selected patients with diarrhea or on clinical suspicion for patients with ileus. Patients with fulminant disease (C. difficile infection with hypotension, shock, ileus, or megacolon) should be treated with oral vancomycin and IV metronidazole, as well as rectal vancomycin in case of ileus. Patients who do not respond to initial therapy should be considered for fecal microbiota transplant or surgery. Proper infection prevention practices decrease C. difficile infection risk. CONCLUSIONS Strong clinical evidence supports limiting antibiotics when possible to decrease C. difficile infection risk. For patients with fulminant C. difficile infection, oral vancomycin reduces mortality, and adjunctive therapies (including IV metronidazole) and interventions (including fecal microbiota transplant) may benefit select patients. Several important questions remain regarding fulminant C. difficile infection management, including which patients benefit from fecal microbiota transplant or surgery.

Abstract
The gastrointestinal (GI) tract consists of trillions of organisms that support multiple functions in the body, from immunity, digestion, and absorption to drug metabolism. These microbes form an overall collection of microorganisms that form the body's microbiome. In critical illness, many of these functions are aberrant, and the microbiome is altered, leading to untoward effects. Some of the most common medications received by patients include antibiotics and proton pump inhibitors, which affect particular changes in the microbiome. In addition, patients receiving prolonged enteral and parenteral nutrition experience changes in the microbiological composition and diversity of their GI tracts. Research is ongoing to characterize the crosstalk between the microbiome and immune function as targets for drug and nutrition therapy.

Abstract
Clostridioides difficile (formerly Clostridium difficile) infection (CDI) represents a worrisome condition, often underestimated, with severe clinical presentations, frequently requiring intensive care unit (ICU) admission. The aim of the present expert statement was to give an overview of the management of CDI in critically ill patients, for whom CDI represents a redoubtable problem, in large part related to the use and abuse of antibiotics. The available knowledge about pathophysiology, risk factors, diagnosis and treatment concerning critical care patients affected by CDI has been reviewed, even though most of the existing information come from studies performed outside the ICU and the evidence on several issues in this specific context is scarce. The adoption of potential preventive and therapeutic strategies aimed to stem the phenomenon were discussed, including the faecal microbiota transplantation. This possibility could represent a highly interesting option in critically ill patients, but current evidence is limited and future well designed studies are needed. A special insight on the specific challenges that the ICU physicians may face caring for the critically ill patients with CDI was also proposed.

Abstract
AbstractThe learning hospital is distinguished by ceaseless evolution of erudition, enhancement, and implementation of clinical best practices. We describe a model for the learning hospital within the framework of a hospital infection prevention program and argue that a critical assessment of safety practices is possible without significant grant funding. We reviewed 121 peer-reviewed manuscripts published by the VCU Hospital Infection Prevention Program over 16 years. Publications included quasi-experimental studies, observational studies, surveys, interrupted time series analyses, and editorials. We summarized the articles based on their infection prevention focus, and we provide a brief summary of the findings. We also summarized the involvement of nonfaculty learners in these manuscripts as well as the contributions of grant funding. Despite the absence of significant grant funding, infection prevention programs can critically assess safety strategies under the learning hospital framework by leveraging a diverse collaboration of motivated nonfaculty learners. This model is a valuable adjunct to traditional grant-funded efforts in infection prevention science and is part of a successful horizontal infection control program.

Abstract
To determine the occurrence of diarrhea and associated factors in critically ill patients with traumatic brain injury (TBI) in use of nutritional therapy. Prospective cohort study conducted in an Intensive Care Unit (ICU) of a General Hospital reference in trauma. We evaluated TBI patients who stayed less than 72 h in the ICU, who were using EN for at least 48 h. Definition of diarrhea it was considered three or more episodes of liquid stools or semi-liquid at 24 h. For analysis were evaluated demographic, epidemiological, clinical and nutritional data. Twenty-three patients were evaluated, being 86.9% male, median 33 years old (IQR = 25-52 years) and 16-day ICU stay (IQR = 10-26 days). Diarrhea occurred in 69.6% of the patients and they had a longer time in the ICU (p = 0.007). All patients who used combination prokinetic therapy (metoclopramide and erythromycin) and used antibiotics for more than 8 days had diarrhea (p = 0.057 and p = 0.007, respectively). The incidence of diarrhea was high in TBI patients with enteral nutrition and was associated with the use of antibiotics for more than one week.

Bayesian joint modeling of bivariate longitudinal and competing risks data: An application to study patient-ventilator asynchronies in critical care patients. Biom J 2017; 59:1184-1203.

Abstract
Mechanical ventilation is a common procedure of life support in intensive care. Patient-ventilator asynchronies (PVAs) occur when the timing of the ventilator cycle is not simultaneous with the timing of the patient respiratory cycle. The association between severity markers and the events death or alive discharge has been acknowledged before, however, little is known about the addition of PVAs data to the analyses. We used an index of asynchronies (AI) to measure PVAs and the SOFA (sequential organ failure assessment) score to assess overall severity. To investigate the added value of including the AI, we propose a Bayesian joint model of bivariate longitudinal and competing risks data. The longitudinal process includes a mixed effects model for the SOFA score and a mixed effects beta regression model for the AI. The survival process is defined in terms of a cause-specific hazards model for the competing risks death or alive discharge. Our model indicates that the SOFA score is strongly related to vital status. PVAs are positively associated with alive discharge but there is not enough evidence that PVAs provide a more accurate indication of death prognosis than the SOFA score alone.

Abstract
Background/Aims Proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs) are commonly prescribed for stress ulcer prophylaxis (SUP) in critically ill patients. Several studies have suggested that the use of PPIs is a potential risk factor for Clostridium difficile infection (CDI). We compared the incidences of CDI in the PPI group and H2RA group for SUP in critically ill patients. Methods From August 2005 to July 2012, the incidences of CDI were retrospectively analyzed in patients who were admitted directly to intensive care units and stayed for more than 3 days. SUP-related CDI was defined as a CDI diagnosed during the SUP period. Patient clinical data were analyzed to identify potential risk factors for SUP-related CDI. Results Of the 1,005 patients enrolled (444 patients received PPI and 561 received H2RA), 38 (3.8%) were diagnosed with SUP-related CDI. The incidence of SUP-related CDI was considerably higher in patients who received PPI than in those who received H2RA (6.7% vs 1.8%). PPI use for SUP (odds ratio [OR], 3.3; confidence interval [CI], 1.5 to 7.1; p=0.003) and diabetes mellitus (OR, 2.3; CI, 1.2 to 4.7; p=0.019) were independent risk factors for SUP-related CDI. Conclusions PPI therapy is associated with a higher risk of SUP-related CDI than H2RA therapy in critically ill patients.

Proton Pump Inhibitors Do Not Increase Risk for Clostridium difficile Infection in the Intensive Care Unit. Am J Gastroenterol 2016; 111:1641-1648. [PMID: 27575714 PMCID: PMC5096970 DOI: 10.1038/ajg.2016.343] [Citation(s) in RCA: 49] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2016] [Accepted: 07/25/2016] [Indexed: 12/11/2022]
Abstract
OBJECTIVES Patients in the intensive care unit (ICU) frequently receive proton pump inhibitors (PPIs) and have high rates of Clostridium difficile infection (CDI). PPIs have been associated with CDI in hospitalized patients, but ICU patients differ fundamentally from non-ICU patients and few studies have focused on PPI use exclusively in the critical care setting. We performed a retrospective cohort study to determine the associations between PPIs and health-care facility-onset CDI in the ICU. METHODS We analyzed data from all adult ICU patients at three affiliated hospitals (14 ICUs) between 2010 and 2013. Patients were excluded if they had recent CDI or an ICU stay of <3 days. We parsed electronic medical records for ICU exposures, focusing on PPIs and other potentially modifiable exposures that occurred during ICU stays. Health-care facility-onset CDI in the ICU was defined as a newly positive PCR for the C. difficile toxin B gene from an unformed stool, with subsequent receipt of anti-CDI therapy. We analyzed PPIs and other exposures as time-varying covariates and used Cox proportional hazards models to adjust for demographics, comorbidities, and other clinical factors. RESULTS Of 18,134 patients who met the criteria for inclusion, 271 (1.5%) developed health-care facility-onset CDI in the ICU. Receipt of antibiotics was the strongest risk factor for CDI (adjusted HR (aHR) 2.79; 95% confidence interval (CI), 1.50-5.19). There was no significant increase in risk for CDI associated with PPIs in those who did not receive antibiotics (aHR 1.56; 95% CI, 0.72-3.35), and PPIs were actually associated with a decreased risk for CDI in those who received antibiotics (aHR 0.64; 95% CI, 0.48-0.83). There was also no evidence of increased risk for CDI in those who received higher doses of PPIs. CONCLUSIONS Exposure to antibiotics was the most important risk factor for health-care facility-onset CDI in the ICU. PPIs did not increase risk for CDI in the ICU regardless of use of antibiotics.

Abstract
Abstract
Introduction: The increased incidence of nosocomial infections in intensive care units, with frequent occurrence of multiresistant pathogens increase mortality and often raises therapeutic problems.
Objectives: to assess the incidence of nosocomial infections, and risk factors.
Methods: The study includes 125 patients hospitalized in the Clinic of Anesthesiology and Intesive Care in the Emergency County Hospital and Cardiovascular Surgery Targu Mures. The patients were divided into two groups: the control group (n = 99), patients who did not develop infections during hospitalization in the ICU and the group with infection (n = 26).
Results: The incidence of nosocomial infections in our intensive care unit was 19.1%, the most common pathogen being Acinetobacter baumanii. There were no significant differences between the two groups regarding demographic data, the most important risk factor was chronic alcohol consumption. SAPS II. and SOFA scores showed higher values in the group with infection on the day of admission. This group showed lower levels of arterial blood oxygen (Horowitz index), lower sodium level, and higher number of platelets compared to the control group. The mortality in the group with infection was 47.65% compared to the control.
Conclusions: Nosocomial infections in critically ill patients are associated with hypoxemia, thrombocytopenia, hyponatremia and a bad outcome.

Epidemiological and economic burden of Clostridium difficile in the United States: estimates from a modeling approach. BMC Infect Dis 2016; 16:303.

Abstract
BACKGROUND Despite a large increase in Clostridium difficile infection (CDI) severity, morbidity and mortality in the US since the early 2000s, CDI burden estimates have had limited generalizability and comparability due to widely varying clinical settings, populations, or study designs. METHODS A decision-analytic model incorporating key input parameters important in CDI epidemiology was developed to estimate the annual number of initial and recurrent CDI cases, attributable and all-cause deaths, economic burden in the general population, and specific number of high-risk patients in different healthcare settings and the community in the US. Economic burden was calculated adopting a societal perspective using a bottom-up approach that identified healthcare resources consumed in the management of CDI. RESULTS Annually, a total of 606,058 (439,237 initial and 166,821 recurrent) episodes of CDI were predicted in 2014: 34.3 % arose from community exposure. Over 44,500 CDI-attributable deaths in 2014 were estimated to occur. High-risk susceptible individuals representing 5 % of the total hospital population accounted for 23 % of hospitalized CDI patients. The economic cost of CDI was $5.4 billion ($4.7 billion (86.7 %) in healthcare settings; $725 million (13.3 %) in the community), mostly due to hospitalization. CONCLUSIONS A modeling framework provides more comprehensive and detailed national-level estimates of CDI cases, recurrences, deaths and cost in different patient groups than currently available from separate individual studies. As new treatments for CDI are developed, this model can provide reliable estimates to better focus healthcare resources to those specific age-groups, risk-groups, and care settings in the US where they are most needed.

Abstract
This tutorial presents a systematic approach to the management of diarrhea in the critical care setting. Diarrhea is a common and prevalent problem in critically ill patients. Despite the high prevalence, its management is far from simple. Professionals are confronted with a myriad of definitions based on frequency, consistency, and volume. The causes are complex and multifactorial, yet enteral tube feeding formula is believed to be the perpetrator. Potential causes for diarrhea are discussed, and 3 case reports provide context to examine the treatment from a nutrition perspective. Each scenario is comprehensively addressed discussing potential causes and providing specific clinical strategies contributing to improved bowel function in this patient group. The approach used for diarrhea management is based on a complete understanding of enteral tube formula, their composition, and their impact in the presence of gut dysfunction. Choosing the right feeding formula may positively influence bowel function and contribute to improved nutrition.

Abstract
BACKGROUND Clostridium difficile is a key culprit underlying nosocomial infectious diarrhea. We investigated the effect of C difficile-associated diarrhea (CDAD) on morbidity and mortality in severely burned children and CDAD risk factors. METHODS After review of 2,840 records, 288 pediatric burn patients were identified as having stool output of >10 mL•kg(-1)•min(-1) for ≥2 successive days and had stool samples immunoassayed for toxins A and B. A case control analysis was performed by matching cases to controls via logistic regression and propensity scores so that age, admission time, and time of occurrence could be controlled; the endpoints were mortality and hospitalization time. RESULTS Eighteen patients tested positive for C difficile toxins (median age, 4 years; mean total body surface area burned, 59%). In the CDAD group, unadjusted in-hospital mortality was 28% (odds ratio, 5.4; 95% CI, 1.7-16.7; P = .01). Hospitalization averaged 48 days in the CDAD group and 38 days in the non-CDAD group (P = .24). Duration of stay per percent total body surface area burned was greater in the CDAD group (0.82 ± 0.4 vs 0.60 ± 0.4; P = .03), as were prolonged bouts of diarrhea complicated by acidosis (13 ± 16 vs 4 ± 5 days; P < .005). Of the 18 possible risk factors evaluated, inhalation injury diagnosed at admission occurred more often in CDAD patients than matched controls (59% vs 31%; P = .04). CONCLUSION CDAD during hospitalization is associated with greater mortality after burns. Inhalation injury increases the likelihood of C difficile infection. Whether C difficile infection is an indication of greater illness among certain burned patients is unknown.

Abstract
Incidence, pathogenesis, diagnostic techniques and therapeutic management of CDI have prompted abundant and adequate recent literature. However, report on clinical manifestations of CDI is frequently biased by the type of patients selected, the retrospective nature of many papers, the epidemic or endemic characteristics of the population reported. This article seeks to review some less discussed clinical and epidemiological aspects of CDI trying to include the clinical manifestations of this disease in unselected populations and also including discussion of CDI in specific groups of patients such as patients without colon and rectum, pediatric and critical care patients.

Abstract
SUMMARYOver the past two decades Clostridium difficile infection (CDI) has appeared as a major public health threat. We performed a retrospective study based on the records of patients hospitalized for CDI at the University Hospital in Krakow, Poland, between 2008 and 2014. In the study period, CDI occurred in 1009 individuals. There were 790 (78%) individuals who developed infection only once, whereas 219 (22%) developed infection more than once. The percentage of deaths within 14 days of CDI confirmation was 2·4%, with a mean age of 74·2 ± 15·9 years. Crude mortality was 12·9% in medical wards, 5·6% for surgical wards and 27·7% in the ICU setting. The time span between diagnosis and death was 5·1 days on average. Between 2008 and 2012 a 6·5-fold increase of CDI frequency with a posterior stabilization and even reduction in 2013 and 2014 was observed. According to the data analysed, 2/3 patients in our population developed CDI during their hospitalization even though they were admitted for different reasons. Medical wards pose a significantly higher risk of CDI than the surgical ones. Age is a risk factor for CDI recurrence. In the case of patients who died, death occurred shortly after diagnosis. The first CDI episode poses much higher risk of mortality than the consecutive ones.

Abstract
PURPOSE Despite the high concentration of patients with known risk factors for Clostridium difficile infection (CDI) in intensive care units (ICUs), data on ICU patients are scarce. The aim of this study was describe the incidence, clinical characteristics, and evolution of CDI in critically ill patients. MATERIALS AND METHODS From 2003 to 2012, adult patients admitted to an ICU (A-ICU) and positive for CDI were included and classified as follows: pre-ICU, if the positive sample was obtained within ±3 days of ICU admission; in-ICU, if obtained after 3 days of ICU admission and up to 3 days after ICU discharge. RESULTS We recorded 4095 CDI episodes, of which 328 were A-ICU (8%). Episodes of A-ICU decreased from 19.4 to 8.7 per 10000 ICU days of stay (P < .0001). Most A-ICU CDIs (66.3%) were mild to moderate. Pre-ICU episodes accounted for 16.2% and were more severe complicated than in-ICU episodes (11% vs 0%; P = .020). Overall mortality was 28.6%, and CDI-attributable mortality was only 3%. CONCLUSION The incidence of A-ICU CDI has decreased steadily over the last 10 years. A significant proportion of A-ICU CDI episodes are pre-ICU and are more severe than in-ICU CDI episodes. Most episodes of A-ICU CDI were nonsevere, with low associated mortality.

Abstract
Introduction Clostridium difficile infection (CDI) is a common cause of nosocomial diarrhea. Metronidazole and vancomycin are the primary treatment options for CDI, but increasing rates of antimicrobial resistance and severe, refractory disease have prompted the need for alternative agents. Tigecycline has previously demonstrated favorable in vitro activity against C. difficile isolates, but clinical data on its use in the treatment of CDI are severely lacking. The objective of this study was to describe our experience using tigecycline in the treatment of severe and severe complicated CDI. Methods This was a retrospective case series of hospitalized patients with severe and severe complicated CDI who were treated with tigecycline. Disease severity assessments were determined according to current practice guidelines. Diagnosis of toxigenic CDI was confirmed by polymerase chain reaction and patients were excluded if they received tigecycline for <48 h. Data were collected by review of the electronic medical record. The primary outcome was clinical cure. Secondary outcomes were sustained response, hospital mortality, and 28-day all-cause mortality. Results A total of 7 cases of severe and complicated CDI were reviewed. Intravenous tigecycline administered as a 100-mg loading dose followed by 50 mg twice daily resulted in clinical cure in 85.7% (n = 6/7) of cases. The majority of patients (n = 4/5) were treated with the novel triple therapy combination of tigecycline, vancomycin, and metronidazole and resulted in clinical cure in 80% (n = 4/5) cases. Sustained response at 28 days was 100% among evaluable cases (n = 5/5). Hospital mortality did not occur in any patients, and 28-day all-cause mortality was 28.6% (n = 2/7). Conclusion Tigecycline appears to be a reasonable addition to the therapeutic regimen in the treatment of severe or complicated CDI, including cases that are refractory to standard therapy. A prospective clinical trial confirming these observational findings is warranted.

Abstract
OBJECTIVE To examine the impact of hospital-onset Clostridium difficile infection (HOCDI) on the outcomes of patients with sepsis. BACKGROUND Most prior studies that have addressed this issue lacked adequate matching to controls, suffered from small sample size, or failed to consider time to infection. DESIGN Retrospective cohort study. SETTING AND PATIENTS We identified adults with a principal or secondary diagnosis of sepsis who received care at 1 of the institutions that participated in a large multihospital database between July 1, 2004 and December 31, 2010. Among eligible patients with sepsis, we identified patients who developed HOCDI during their hospital stay. MEASUREMENTS We used propensity matching and date of diagnosis to match cases to patients without Clostridium difficile infections and compared outcomes between the 2 groups. MAIN RESULTS Of 218,915 sepsis patients, 2368 (1.08%) developed HOCDI. Unadjusted in-hospital mortality was significantly higher in HOCDI patients than controls (25% vs 10%, P < 0.001). After multivariate adjustment, in-hospital mortality rate was 24% in cases vs. 15% in controls. In an analysis limited to survivors, adjusted length of stay (LOS) among cases with Clostridium difficile infections was 5.1 days longer than controls (95% confidence interval: 4.4-5.8) and the median-adjusted cost increase was $4916 (P < 0.001). CONCLUSIONS After rigorous adjustment for time to diagnosis and presenting severity, hospital-acquired Clostridium difficile infection was associated with increased mortality, LOS, and cost. Our results can be used to assess the cost-effectiveness of prevention programs and suggest that efforts directed toward high-risk patient populations are needed.

Abstract
BACKGROUND Clostridium difficile infection (CDI) can lead to complications, recurrence, and death. Numerous studies have assessed risk factors for these unfavourable outcomes, but systematic reviews or meta-analyses published so far were limited in scope or in quality. METHODS A systematic review was completed according to PRISMA guidelines. An electronic search in five databases was performed. Studies published until October 2013 were included if risk factors for at least one CDI outcome were assessed with multivariate analyses. RESULTS 68 studies were included: 24 assessed risk factors for recurrence, 18 for complicated CDI, 8 for treatment failure, and 30 for mortality. Most studies accounted for mortality in the definition of complicated CDI. Important variables were inconsistently reported, such as previous episodes and use of antibiotics. Substantial heterogeneity and methodological limitations were noted, mainly in the sample size, the definition of the outcomes and periods of follow-up, precluding a meta-analysis. Older age, use of antibiotics after diagnosis, use of proton pump inhibitors, and strain type were the most frequent risk factors for recurrence. Older age, leucocytosis, renal failure and co-morbidities were frequent risk factors for complicated CDI. When considered alone, mortality was associated with age, co-morbidities, hypo-albuminemia, leucocytosis, acute renal failure, and infection with ribotype 027. CONCLUSION Laboratory parameters currently used in European and American guidelines to define patients at risk of a complicated CDI are adequate. Strategies for the management of CDI should be tailored according to the age of the patient, biological markers of severity, and underlying co-morbidities.

Abstract
Severe colitis, an umbrella encompassing several entities, is one of the most common acute gastrointestinal disorders resulting in critical illness. Clostridium difficile infection is responsible for the majority of nosocomial diarrhea with fulminant C difficile colitis (CDC) carrying a high mortality. Optimal outcomes can be achieved by early identification and treatment of fulminant CDC, with appropriate surgical intervention when indicated. Ischemic colitis, on the other hand, is uncommon with a range of etiological factors including abdominal aortic surgery, inotropic drugs, rheumatoid diseases, or often no obvious triggering factor. Most cases resolve with nonsurgical management; however, prompt recognition of full-thickness necrosis and gangrene is crucial for good patient outcomes. Fulminant colitis is a severe disease secondary to progressive ulcerative colitis with systemic deterioration. Surgical intervention is indicated for hemorrhage, perforation, or peritonitis and failure of medical therapy to control the disease. Although, failure of medical management is the most common indication, it can be difficult to define objectively and requires a collaborative multidisciplinary approach. This article proposes some simple management algorithms for these clinical entities, with a focus on critically ill patients.

Abstract
Patients in the setting of the intensive care unit can develop intra-abdominal complications that may worsen outcome. Clinical suspicion of such complications coupled with early diagnosis and treatment may reduce morbidity and mortality associated with these processes. This article addresses the diagnosis and management of some of the common causes of intra-abdominal catastrophes.

Abstract
Background: Critically ill patients are at high risk for acquiring Clostridium difficile infection. The aim of this study was to investigate the prevalence, severity, and outcome of neurointensive care unit (NICU) acquired Clostridium difficile associated disease (CDAD). Materials and Methods: Intensive care admission and hospital infection control databases from April 2008 to August 2010 were studied and the case notes reviewed retrospectively. Diarrhea was classified as mild, moderate, or severe based on the frequency and volume. Information on demographics, risk factors for CDAD, presentation, and course of the disease was gathered. Admission diagnosis, days of NICU stay, and incidence of complications were noted. Results: In the time period studied, 9 out of 2212 patients (prevalence rate 0.4%) admitted to the intensive care unit (ICU) for a total of 10,825 bed days (incidence rate 8.3 per 10,000 bed days) acquired CDAD. Median age was 55 (IQR 20–72) years. The median NICU stay was 26 (IQR 11–103) days. The median duration between ICU admission and development of CDAD was 11 (IQR 3–93) days. Four patients (44%) had moderate CDAD. Concurrent infections occurred in seven (77%) patients. The most frequently prescribed antimicrobials prior to CDAD were cephalosporins (71%). The apparent risk factors in this group included age>65 year (22%) and antibiotics (67%) among others. One patient developed CDAD colitis. Three patients had a perceived delay in discharge from the ICU (1–8 days) due to their infective status. No mortality was ascribed to CDAD. Conclusion: The prevalence rate (0.4%) and morbidity of CDAD in the unit are low. A larger database is needed to better analyze the associated risk factors in this subgroup of patients. A possible increase in disease burden due to a delay in discharge from the ICU merits further evaluation.

Abstract
PURPOSE We assessed factors associated with mortality and complicated course in the case of Clostridium difficile infection (CDI) acquired in the intensive care unit (ICU). METHOD Retrospective cohort study conducted from 1 January 2002 through 1 January 2012. All patients who acquired CDI in our ICU were included. RESULTS Thirty-one patients were included. Twenty patients (65 %) had mild colitis, 8 (25 %) moderate colitis, and 3 (10 %) severe colitis. Initial antibiotherapy was metronidazole (n = 30, 97 %) and vancomycin (n = 1, 3 %). Seventeen patients (55 %) experienced at least one complication: failure of initial treatment (n = 16, 52 %), shock (n = 11, 34 %), need for surgery (n = 1, 3 %) or renal replacement (n = 4, 13 %), or death (n = 8, 26 %). Risk factors of ICU mortality were history of corticosteroids prescription, prolonged ICU stay, low serum albumin level, and high Sequential Organ Failure Assessment (SOFA) score at the time of CDI diagnosis. Factors associated with a complicated course were high Simplified Acute Physiology Score (SAPS II), high SOFA score, and low serum albumin level at the time of CDI onset. CONCLUSION Risk factors of poor outcome in patients with CDI acquired in the ICU are different from those in the general population suffering from CDI. The implementation of treatment algorithms taking into account these factors may reduce complication rates in this specific population.

Abstract
Clostridium difficile is a formidable problem in the twenty-first century. Because of injudicious use of antibiotics, the emergence of the hypervirulent epidemic strain of this organism has been difficult to contain. The NAP1/BI/027 strain causes more-severe disease than other widely prevalent strains and affects patients who were not traditionally thought to be at risk for Clostridium difficile infection. Critically ill patients remain at high risk for this pathogen, and preventive measures, such as meticulous contact precautions, hand hygiene, environmental disinfection, and, most importantly, antibiotic stewardship, are the cornerstones of mitigation in the intensive care unit.

Abstract
BACKGROUND Antimicrobial treatment in critically ill patients can either be started as soon as infection is suspected or after objective data confirm an infection. We postulated that delaying antimicrobial treatment of patients with suspected infections in the surgical intensive care unit (SICU) until objective evidence of infection had been obtained would not worsen patient mortality. METHODS We did a 2-year, quasi-experimental, before and after observational cohort study of patients aged 18 years or older who were admitted to the SICU of the University of Virginia (Charlottesville, VA, USA). From Sept 1, 2008, to Aug 31, 2009, aggressive treatment was used: patients suspected of having an infection on the basis of clinical grounds had blood cultures sent and antimicrobial treatment started. From Sept 1, 2009, to Aug 31, 2010, a conservative strategy was used, with antimicrobial treatment started only after objective findings confirmed an infection. Our primary outcome was in-hospital mortality. Analyses were by intention to treat. FINDINGS Admissions to the SICU for the first and second years were 762 and 721, respectively, with 101 patients with SICU-acquired infections during the aggressive year and 100 patients during the conservative year. Compared with the aggressive approach, the conservative approach was associated with lower all-cause mortality (13/100 [13%] vs 27/101 [27%]; p=0·015), more initially appropriate therapy (158/214 [74%] vs 144/231 [62%]; p=0·0095), and a shorter mean duration of therapy (12·5 days [SD 10·7] vs 17·7 [28·1]; p=0·0080). After adjusting for age, sex, trauma involvement, acute physiology and chronic health evaluation (APACHE) II score, and site of infection, the odds ratio for the risk of mortality in the aggressive therapy group compared with the conservative therapy group was 2·5 (95% CI 1·5-4·0). INTERPRETATION Waiting for objective data to diagnose infection before treatment with antimicrobial drugs for suspected SICU-acquired infections does not worsen mortality and might be associated with better outcomes and use of antimicrobial drugs.

Abstract
Background Clostridium difficile infection (CDI) is a common cause of diarrhoea in hospitalised patients. Around the world, the incidence and severity of CDI appears to be increasing, particularly in the northern hemisphere. The purpose of this integrative review was to investigate and describe mortality in hospitalised patients with CDI. Methods A search of the literature between 1 January 2005 and 30 April 2011 focusing on mortality and CDI in hospitalised patients was conducted using electronic databases. Papers were reviewed and analysed individually and themes were combined using integrative methods. Results All cause mortality at 30 days varied from 9% to 38%. Three studies report attributable mortality at 30 days, varying from 5.7% to 6.9%. In hospital mortality ranged from 8% to 37.2% Conclusion All cause 30 day mortality appeared to be high, with 15 studies indicating a mortality of 15% or greater. Findings support the notion that CDI is a serious infection and measures to prevent and control CDI are needed. Future studies investigating the mortality of CDI in settings outside of Europe and North America are needed. Similarly, future studies should include data on patient co-morbidities.

Searches in PubMed and Scopus were performed by two reviewers independently. Data regarding treatment failure and recurrence following metronidazole and vancomycin treatment were extracted and analysed. In total, 39 articles (7005 patients) were selected for inclusion in the systematic review. The reported treatment failure was 22.4% with metronidazole (16 studies) and 14.2% with vancomycin (8 studies). Recurrence of CDI occurred in 27.1% of patients following metronidazole treatment (18 studies) and 24.0% of patients following vancomycin treatment (8 studies). Mean treatment failure and recurrence in the selected studies was 22.3% (24 studies) and 22.1% (37 studies). The reported outcomes depended on the study design (higher in prospective and retrospective cohort studies than in randomised controlled trials), geographic location of the study (higher in North America than in Europe and Asia), funding (higher in studies funded by non-profit organisations than pharmaceutical companies), mean age of the studied population (higher in older patients) and duration of follow-up (higher in studies with follow-up >1 month). In conclusion, infection with C. difficile is associated with 22.4% and 14.2% treatment failure and 27.1% and 24.0% recurrence after treatment with metronidazole and vancomycin, respectively. The variation in the reported outcomes amongst studies depends on the study design, location, funding, age and follow-up period.

Abstract
OBJECTIVES To determine the prevalence, severity, and outcome associated with Clostridium difficile-associated disease (CDAD) acquired while in the cardiothoracic intensive care unit (CTICU). DESIGN A 5-year retrospective study. SETTING The CTICU. PARTICIPANTS All CTICU patients with a positive C difficile stool toxin assay 48 hours after admission. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The results of all CTICU patients with a positive C difficile stool toxin assay were obtained from the Microbiology Department. Each patient's medical notes and charts then were reviewed in turn. A total of 27 of 5,199 (0.5%) CTICU patients acquired CDAD. The median age was 74 years (IQR 68-77), and 17 (63%) patients were male. There were 21 (78%) surgical patients; 13 (62%) were elective admissions. The most frequent diagnosis on admission was valvular heart disease (10 [37%] patients). Sixteen (59%) patients underwent coronary artery bypass graft (CABG) surgery and/or valvular heart surgery. The median interval between CTICU admission and CDAD diagnosis was 10 days (IQR 5-18). Previously identified risk factors for ICU-acquired CDAD included age >65 years (23), antibiotic use (26), and medical device requirements (27). At the time of diagnosis, 14 (52%) patients had moderate CDAD. After treatment initiation, 8 (30%) patients developed worsening CDAD. The 30-day in-hospital mortality rate for CTICU-acquired CDAD was 26% (7 patients). CONCLUSIONS C difficile-associated disease rarely is acquired in the CTICU. Approximately one third of patients may experience disease progression, and just over a quarter may die within 30 days of diagnosis. The implementation of recommended severity definitions and treatment algorithms may reduce complication rates and merits prospective evaluation.

Abstract
Clostridium difficile infection (CDI) management has become more daunting over the past decade because of alarming increases in CDI incidence and severity both in the hospital and in the community. This increase has concomitantly caused significant escalation of the health-care economic burden caused by CDI, and it will likely be translated to increased ICU admission and attributable mortality. Some possible causes for difficulty in management of CDI are as follows: (1) inability to predict and prevent development of severe/complicated or relapsing CDI in patients who initially present with mild symptoms; (2) lack of a method to determine who would have benefited a priori from initiating vancomycin treatment first instead of treatment with metronidazole; (3) lack of sensitive and specific CDI diagnostics; (4) changing epidemiology of CDI, including the emergence of a hypervirulent, epidemic C difficile strain associated with increased morbidity and mortality; (5) association of certain high-usage nonantimicrobial medications with CDI; and (6) lack of treatment regimens that leave the normal intestinal flora undisturbed while treating the primary infection. The objective of this article is to present current management and prevention guidelines for CDI based on recommendations by the Society for Healthcare Epidemiology of America and Infectious Diseases Society of America and potential new clinical management strategies on the horizon.

Abstract
BACKGROUND Vancomycin-resistant Enterococcus (VRE) colonization of the gastrointestinal tract shares similar risk factors with Clostridium difficile infection. We sought to elucidate the prevalence and risk factors of VRE colonization associated with C difficile infection. METHODS All adult inpatients with C difficile infection from July 2006 to October 2006 were prospectively evaluated. All C difficile toxin-positive stool samples were screened for detection of VRE. Risk factors for VRE colonization were compared in patients with C difficile infection with and without VRE colonization. RESULTS Of the 158 cases of C difficile infection evaluated, 88 (55.7%) involved VRE colonization. Independent risk factors for VRE colonization were admission from long-term care facilities (P = .013), dementia (P = .017), and hospitalization in the previous 2 months (P = .014). No statistically significant difference between C difficile infection cases with and without VRE colonization in terms of previous receipt (within 1 month) of antibiotics, including metronidazole and vancomycin, was found on multivariate analysis. C difficile infection cases with VRE colonization had a higher prevalence of coinfection with methicillin-resistant Staphylococcus aureus (P = .002) and Acinetobacter spp (P = .006). CONCLUSION VRE colonization was associated with >50% of C difficile infection cases and with a higher rate of coinfection with multidrug-resistant pathogens. Given the high rate of C difficile infection associated with VRE colonization, active surveillance of VRE in patients with C difficile infection is reasonable in high-risk settings.
