Clostridium Infections - Top 30 Publications

Recurrent bacteremia and liver abscess caused by Clostridium difficile: A case report.

Clostridium difficile bacteremia (CDB) and liver abscess is a quite rare presentation of C. difficile infection.

Botulism: Diagnosis and Therapy.

Background Botulism is a rare, life-threatening, time-critical neuroparalytic disease that is frequently a subject of differential diagnostic considerations. But there is much uncertainty regarding diagnosis and therapy. Rapid diagnosis, early antitoxin dose, consistent food hygiene and the sensitization of the population can help to reduce incidence, morbidity and mortality. Methods This overview is based on an epidemiological data inquiry (RKI, ECDC, CDC, WHO) and a selective literature research (pubmed till March 2017). Additionally, the German botulism guideline (2012) and own diagnostical experiences were taken into account. Results The incidence of botulinum toxin intoxication induced by ubiquitous spore-forming Clostridium botulinum (main representative) is < 0.01/100 000 EU citizens. Foodborne botulism is a pure intoxication syndrome (most common form) due to improperly prepared or incorrectly stored food. Wound and infant botulism are kinds of "toxico-infections". A "bulbar" neuroparalysis is a main symptom progressing to a flaccid tetraparesis up to respiratory paralysis. Infant botulism is presented non-specific and is treated only symptomatically; but a special human-derived antitoxin is available at international pharmacies. In case of suspected foodborne or wound botulism antitoxin must be administered as soon as possible, which may also be effective 24 hours after symptoms onset. There is no evidence for adjuvant treatment except of intensive care unit (ICU) therapy. Conclusion Despite typical symptomatology botulism is often diagnosed too late. Early antitoxin administration and ICU therapy are crucial for survival. A consultant laboratory should be contacted for advice.

Six Things You Can Do Today to Prevent Hospital-Onset C. difficile Tomorrow.

Some lesser-known advice on keeping patients safe.

Faecal microbiota transplantation for <em>Clostridium difficile</em>-associated diarrhoea: a systematic review of randomised controlled trials.

Faecal microbiota transplantation (FMT) has emerged as a useful approach for treating Clostridium difficile-associated diarrhoea (CDAD). Randomised controlled trials (RCTs) have recently evaluated its effectiveness, but systematic reviews have focused on evidence from case series. We therefore conducted a systematic review and meta-analysis of RCTs evaluating the effectiveness of FMT for treating CDAD.

Predictors of 30-Day Mortality in Hospitalized Patients with Clostridium difficile Infection.

Clostridium difficile infection (CDI) is a significant cause of morbidity and mortality and is the most common nosocomial infection in the United States, with associated annual costs of approximately $3 billion. The epidemiology of CDI has changed with the identification of novel risk factors for incident and recurrent CDI. The aim of this study was to identify the predictors of 30-day mortality in hospitalized patients with CDI.

Diphtheria, pertussis, and tetanus: evidence-based management of pediatric patients in the emergency department

Diphtheria, pertussis, and tetanus are potentially deadly bacterial infections that are largely preventable through vaccination, though they remain in the population. This issue reviews the epidemiology, pathophysiology, diagnosis, and current recommended emergency management of these conditions. Disease-specific medications, as well as treatment of the secondary complications, are examined in light of the best current evidence. Resources include obtaining diphtheria antitoxin from the United States Centers for Disease Control and Prevention and best-practice recommendations with regard to testing, involvement of government health agencies, isolation of the patient, and identification and treatment of close contacts. Most importantly, issues regarding vaccination and prevention are highlighted.

Risk of surgical site infection, acute kidney injury, and Clostridium difficile infection following antibiotic prophylaxis with vancomycin plus a beta-lactam versus either drug alone: A national propensity-score-adjusted retrospective cohort study.

The optimal regimen for perioperative antimicrobial prophylaxis is controversial. Use of combination prophylaxis with a beta-lactam plus vancomycin is increasing; however, the relative risks and benefits associated with this strategy are unknown. Thus, we sought to compare postoperative outcomes following administration of 2 antimicrobials versus a single agent for the prevention of surgical site infections (SSIs). Potential harms associated with combination regimens, including acute kidney injury (AKI) and Clostridium difficile infection (CDI), were also considered.

Description and validation of a new automated surveillance system for Clostridium difficile in Denmark.

The surveillance of Clostridium difficile (CD) in Denmark consists of laboratory based data from Departments of Clinical Microbiology (DCMs) sent to the National Registry of Enteric Pathogens (NREP). We validated a new surveillance system for CD based on the Danish Microbiology Database (MiBa). MiBa automatically collects microbiological test results from all Danish DCMs. We built an algorithm to identify positive test results for CD recorded in MiBa. A CD case was defined as a person with a positive culture for CD or PCR detection of toxin A and/or B and/or binary toxin. We compared CD cases identified through the MiBa-based surveillance with those reported to NREP and locally in five DCMs representing different Danish regions. During 2010-2014, NREP reported 13 896 CD cases, and the MiBa-based surveillance 21 252 CD cases. There was a 99·9% concordance between the local datasets and the MiBa-based surveillance. Surveillance based on MiBa was superior to the current surveillance system, and the findings show that the number of CD cases in Denmark hitherto has been under-reported. There were only minor differences between local data and the MiBa-based surveillance, showing the completeness and validity of CD data in MiBa. This nationwide electronic system can greatly strengthen surveillance and research in various applications.

Paediatric otogenic tetanus: an evidence of poor immunization in Nigeria.

Suppurative otitis media is a common childhood infection that predisposes to otogenic tetanus. Tetanus is a vaccine preventable disease that is associated with high cost of care and mortality. This study highlights reasons for otogenic tetanus in Nigerian children and way of reducing the menace. This is a 5-year retrospective review of all patients managed for otogenic tetanus in at the Department of Otorhinolaryngology, University College Hospital, Ibadan. The data collected include demographic, clinical presentations, tetanus immunisation history, and duration of hospital admission, and management- outcome. There were 23 patients comprising of 13(56.5 %) males and 10 (43.5%) females, male to female ratio was 1.3:1. The age ranged between 11 months and12 years (mean age 3.4 years ± 2.1). All the patients presented with discharging ear, trismus and spasms. The onset of symptoms prior hospital presentation ranged between 2 - 11 days (mean 3.0 days ± 1.3). Only 12(52.1%) patients had complete childhood tetanus immunisation, 6(26.1) % had no tetanus immunisation and no other childhood immunisation, while 5(21.7%) had partial tetanus immunisation. The discharging ears were managed by self-medication and other harmful health practices. The hospital admission ranged from 20 days - 41days (average of 23days) and there were 3(13.0 %) death. Tetanus immunization was not received because of; non- availability of the vaccine at health centers, lack of health facility in communities, fear of complications from immunization, poor awareness of the immunization programme. Tetanus, an immunisable disease, is still a major problem in Nigeria.

Increasing Incidence of Multiply Recurrent Clostridium difficile Infection in the United States: A Cohort Study.

Clostridium difficile infection (CDI), the most common health care-associated infection, often recurs. Fecal microbiota transplantation is increasingly used to treat multiply recurrent CDI (mrCDI).

Characterization of Clostridium perfringens Strains Isolated from Healthy and Necrotic Enteritis-Afflicted Broiler Chickens.

Necrotic enteritis (NE) is an important enteric disease in poultry, and Clostridium perfringens (CP) type A strains are the primary etiology. NE is responsible for annual losses of US $6 billion to the poultry industry in the United States. An increase in the incidence of NE has been also associated with withdrawal of antibiotic growth promoters from poultry feed. In this study, CP strains isolated from healthy and NE-afflicted birds were characterized microbiologically and molecularly, and their virulence was experimentally tested in chickens. All strains were hemolytic, lecithinase positive, and identified as CP by biochemical tests. Three distinct colony morphologies were seen in brain-heart infusion media with 0.3% agarose, FeSO4, and ZnCl2. The CP strains responded differently to iron chelation with 2,2'-bidypinol. PCR toxinotyping showed that all tested strains were alpha toxin-positive, seven (N11, N10, CP1, CP5, CP13, JGS, and Del1) were beta2-toxin-positive, and only one (Del1) was necrotic enteritis toxin B-like-positive. In vivo studies indicated that most isolates, including strain N11 isolated from the normal chicken gut, were sufficiently virulent to produce NE disease in the Eimeria/CP dual infection model. The Del1 and N11 strains merit further investigation to identify their virulence factors and immune-protective antigens.

Fatal course of takotsubo cardiomyopathy in a female with recurrent Clostridium difficile infection.

Among diverse triggering factors of stress-induced takotsubo cardiomyopathy (TC), a viral or bacterial infection is rarely observed. Sepsis is an exception, regardless of the etiologic pathogen, in which case an excess of catecholamines may result in acute left ventricular dysfunction. TC precipitated by Clostridium difficile infection (CDI) has been reported only in two patients so far.

Tetanus after cat scratch and bites in a previously immunized patient.

Tetanus is declining due to vaccination, professional labor management and appropriate wound care. Tetanus cases have been reported despite immunization. We report the case of a previously healthy 21 years old female patient that presented a mild generalized tetanus requiring admission after mild and recurrent cat scratch and bites. She had received six vaccine shots during childhood, and a booster dose five years earlier after a rabbit bite. Symptoms appeared seven weeks after the last contact, and included headache, muscle spasms and mild opisthotonus. Laboratory evaluation, including CSF analysis and microbiological investigation, as well as imaging studies were all normal. The patient received 6,000 IU of human antitoxin immunoglobulin. No autonomic manifestations or respiratory compromise were registered. Symptoms resolved rapidly and she was discharge after seven days with an order to complete a tetanus toxoid immunization schedule with three doses.

Effect of antibiotic stewardship on the incidence of infection and colonisation with antibiotic-resistant bacteria and Clostridium difficile infection: a systematic review and meta-analysis.

Antibiotic stewardship programmes have been shown to reduce antibiotic use and hospital costs. We aimed to evaluate evidence of the effect of antibiotic stewardship on the incidence of infections and colonisation with antibiotic-resistant bacteria.

Antibiotic prophylaxis for surgical site infections as a risk factor for infection with Clostridium difficile.

We aimed to measure the association between 2013 guideline concordant prophylactic antibiotic use prior to surgery and infection with Clostridium difficile.

Compliance with Clostridium difficile treatment guidelines: effect on patient outcomes.

Guidelines for the severity classification and treatment of Clostridium difficile infection (CDI) were published by Infectious Diseases Society of America (IDSA)/Society for Healthcare Epidemiology of America (SHEA) in 2010; however, compliance and efficacy of these guidelines has not been widely investigated. This present study assessed compliance with guidelines and its effect on CDI patient outcomes as compared with before these recommendations. A retrospective study included all adult inpatients with an initial episode of CDI treated in a single academic center from January 2009 to August 2014. Patients after guideline publication were compared with patients treated in 2009-2010. Demographic, clinical, and laboratory data were collected to stratify for disease severity. Outcome measures included compliance with guidelines, mortality, length of stay (LOS), and surgical intervention for CDI. A total of 1021 patients with CDI were included. Based upon the 2010 guidelines, 42 (28·8%) of 146 patients treated in 2009 would have been considered undertreated, and treatment progressively improved over time, as inadequate treatment decreased to 10·0% (15/148 patients) in 2014 (P = 0·0005). Overall, patient outcomes with guideline-adherent treatment decreased CDI attributable mortality twofold (P = 0·006) and CDI-related LOS by 1·9 days (P = 0·0009) when compared with undertreated patients. Compliance with IDSA/SHEA guidelines was associated with a decreased risk of mortality and LOS in hospitalized patients with CDI.

Assessing the effect of patient screening and isolation on curtailing Clostridium difficile infection in hospital settings.

Patient screening at the time of hospital admission is not recommended as a routine practice, but may be an important strategy for containment of Clostridium difficile infection (CDI) in hospital settings. We sought to investigate the effect of patient screening in the presence of asymptomatic carriers and in the context of imperfect patient isolation.

Treatment With Fecal Microbiota Transplantation: The Need for Complete Methodological Reporting for Clinical Trials.

Fulminant Course of a Clostridium Perfringens Infection with Pathognomonic CT finding.

History and clinical findings A 74-year old woman was accepted by the emergency room with severe chest and abdominal pain. She complained about regurgitation after ingestion of food followed by sharp pain in her breast. Investigations A first examination of the patient showed a tachypnoea und tachycardia up to 122 beats per minute, the body temperature measured on admission was 38.7 °C. Due to hemolysis only a few of the requested parameters could be evaluated. CRP was increased with 8.32 mg/dl. The hemoglobin dropped from 12.0 g/dl to 10.3 g/dl during 4 hours. A computed tomography scan was done because of severe worsening of the patient's condition. The CT scan showed two cavities in the right lobe of the liver filled with gas. Treatment and course Initial antibiotic therapy with Ceftriaxon was immediately started. During her stay in the emergency room the patient showed a severe worsening of her condition. Therefore a CT scan was initiated after the abdominal ultrasound revealed nothing specific. During the CT examination the patient stopped breathing sufficiently, followed by hematuria and vomiting a large amount of blood. The patient died 8.5 hours of an irreversible cardiovascular failure after admission to the hospital. Conclusion A rapid decline of the patient's condition in addition to hemolysis and a gas-filled liver necrosis are pathognomonic signs for an infection with clostridium perfringens which requires immediate treatment. Only an immediate surgical intervention in combination with an adapted antibiotic increases chances of survival in patients with clostridia.

Identification of novel risk factors for community-acquired Clostridium difficile infection using spatial statistics and geographic information system analyses.

The rate of community-acquired Clostridium difficile infection (CA-CDI) is increasing. While receipt of antibiotics remains an important risk factor for CDI, studies related to acquisition of C. difficile outside of hospitals are lacking. As a result, risk factors for exposure to C. difficile in community settings have been inadequately studied.

Changes in microbial ecology after fecal microbiota transplantation for recurrent C. difficile infection affected by underlying inflammatory bowel disease.

Gut microbiota play a key role in maintaining homeostasis in the human gut. Alterations in the gut microbial ecosystem predispose to Clostridium difficile infection (CDI) and gut inflammatory disorders such as inflammatory bowel disease (IBD). Fecal microbiota transplantation (FMT) from a healthy donor can restore gut microbial diversity and pathogen colonization resistance; consequently, it is now being investigated for its ability to improve inflammatory gut conditions such as IBD. In this study, we investigated changes in gut microbiota following FMT in 38 patients with CDI with or without underlying IBD.

Protective Factors in the Intestinal Microbiome Against Clostridium difficile Infection in Recipients of Allogeneic Hematopoietic Stem Cell Transplantation.

Clostridium difficile infection (CDI) is a frequent complication in recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT), who receive intensive treatments that significantly disrupt the intestinal microbiota. In this study, we examined the microbiota composition of allo-HSCT recipients to identify bacterial colonizers that confer protection against CDI after engraftment.

Health Maintenance Deficits in a Fully Insured Population of Adolescents With Chronic Medical Conditions.

The current national monitoring of routine wellness care and vaccine uptake does not provide data on health maintenance among pediatric populations with chronic medical conditions. In this case-control study that analyzes wellness visits and vaccine uptake among adolescents, ages 16 to 18 years, we identified 938 without (controls) and 74 with (cases) 1 of 12 specific chronic medical conditions. The PPSV23 (23-valent pneumococcal polysaccharide vaccine) is recommended by the Advisory Committee on Immunization Practices for these 12 conditions and served as a measure of uptake for medically indicated vaccines. Our controls were twice as likely as cases to have a documented well visit in the past year, and there was a significantly higher proportion of controls than cases vaccinated with Tdap (tetanus toxoid, reduced diphtheria toxoid, acellular pertussis), MCV-4 (quadrivalent meningococcal conjugate), and HPV (human papillomavirus), all P < .05. More than 60% of cases failed to receive PPSV23. Adolescents with chronic medical conditions are at high risk of neglecting routine health maintenance.

Nursing a critically ill tetanus patient in an intensive care unit in Zambia.

The global incidence of tetanus has been gradually reducing. Improvements in vaccination and health education programmes and the World Health Organization campaign to eradicate maternal and neonatal tetanus have all resulted in fewer presentations globally. Unfortunately, tetanus mortality remains a significant problem for many developing countries, owing to inadequate vaccination programmes or to conflict or humanitarian disasters during which vaccination programmes are stopped or there is sporadic cover. This case study explores the care of a tetanus patient in an intensive care unit in Zambia, a lower-middle-income country in sub-Saharan Africa.

Higher Incidence of Clostridium difficile Infection Among Individuals With Inflammatory Bowel Disease.

Studies of Clostridium difficile infections (CDIs) among individuals with inflammatory bowel disease (IBD) have used data from single centers or CDI administrative data codes of limited diagnostic accuracy. We determined the incidence, risk factors, and outcomes after CDI in a population-based cohort of patients with IBD and laboratory confirmation diagnoses of CDI.

Management of antibiotic-associated pseudomembranous colitis in Non-hospitalized and hospitalized patients.

Proper management of antibiotic-associated pseudo membranous colitis is not clear. This article is to investigate proper treatment of antibiotic-associated pseudo membranous colitis. Data of 67 patients (aged 18-69 years, with 31 males and 46 females) with antibiotic-associated pseudo membranous colitis were retrospectively analyzed including the demography, antibiotics to induce and for treatment of the pseudo membranous colitis, and other supportive measures. All 67 patients had a positive cytotoxin test, which confirmed the pseudo membranous colitis. Antibiotics which induced the pseudo membranous colitis included clindamycin, ofloxacin, piperacillin, cefatriaxone, penbritin and ceftazidime. Once the correct diagnosis was made, the culprit antibiotics were discontinued immediately, and narrow-spectrum antibiotics like metronidazole and vancomycin were administered in combination with correction of fluid and electrolyte abnormalities, use of vitamins C and B complex to repair the intestinal mucosa, and avoidance of antispasmodic and antidiarrheal agents. After appropriate treatment for 2-20 days, all patients recovered with no sequela. Sixty-two patients were clinically cured while five (7.5%) had diarrhea recurrence within two months of the end of therapy. Retreatment with tapering and extended period of metronidazole and/or vancomycin led to complete recovery of the patients. Multiple antibiotic agents are associated with pseudo membranous colitis, and correction of fluid and electrolyte abnormalities and use of vitamins to repair the intestinal mucosa should be performed to speed up the cure process.

Tracking microbial colonization in fecal microbiota transplantation experiments via genome-resolved metagenomics.

Fecal microbiota transplantation (FMT) is an effective treatment for recurrent Clostridium difficile infection and shows promise for treating other medical conditions associated with intestinal dysbioses. However, we lack a sufficient understanding of which microbial populations successfully colonize the recipient gut, and the widely used approaches to study the microbial ecology of FMT experiments fail to provide enough resolution to identify populations that are likely responsible for FMT-derived benefits.
