PURPOSE: Diarrhea is one of the leading causes of mortality in children living in developing countries. The etiology of acute diarrhea in each healthcare center varies depending on place, time, and population. This study aimed to identify pathogen patterns in human immunodeficiency virus (HIV)-infected and non-HIV children suffering from acute diarrhea, using multiplex real time reverse transcriptase polymerase chain reaction (RT-PCR), in an Indonesian tertiary hospital. METHODS: This cross-sectional study was conducted at Dr...

INTRODUCTION: Diagnosis of Clostridioides difficile infection (CDI) depends on clinical presentation and laboratory testing. Stool diagnostic tests are essential for effective detection of toxigenic C. difficile strains. No study to date has evaluated the readability of microbiology labs in Saudi Arabia to test for CDI and evaluated the knowledge and practice of healthcare providers regarding CDI management. Therefore, this study aimed to assess the knowledge and practice of healthcare providers in Saudi Arabia regarding CDI diagnosis and treatment...

BACKGROUND: Diarrhea is a common complication of hematopoietic stem cell transplantation (HSCT) and is associated with substantial morbidity, but its etiology is often unknown. Etiologies of diarrhea in this population include infectious causes, chemotherapy- or medication-induced mucosal injury and graft-versus-host disease (GVHD). Distinguishing these potential causes of diarrhea is challenging since diarrheal symptoms are often multifactorial, and the etiologies often overlap in transplant patients...

OBJECTIVES: Fecal microbiota transplantation (FMT) is an emerging option for recurrent or refractory Clostridium difficile -associated diarrhea (CDAD). We describe a single-center experience of FMT in hematopoietic stem cell transplant (HSCT) recipients with CDAD in India. METHODS: A prospective observational study of HSCT recipients with CDAD who received FMT in our center. RESULTS: A total of 13 patients were included. All the patients were allogenic HSCT recipients; FMT was performed in seven patients due to refractory CDAD, in five patients due to the presence of both CDAD and graft vs host disease (GVHD), and in 1 patient due to recurrent CDAD...

A 74-year-old male presenting with bloody stools was diagnosed with advanced rectal cancer. He underwent robot- assisted low anterior resection and temporary ileostomy. Cefmetazole(CMZ)was administered during surgery and on postoperative day(POD)1. His postoperative course was generally good. On POD8, he developed abdominal fullness, vomiting, renal dysfunction, and hyperkalemia. Plain CT revealed small bowel ileus and outlet obstruction with ileostomy was suspected. A nasogastric tube was placed in the stomach, and a balloon catheter was inserted from the ileostomy to the oral side of the ileum...

Pseudomembranes in the large and small intestines are common in hospitalized patients that are immunosuppressed or on certain oral antibiotics. Pseudomembranous enterocolitis, histologically characterized by volcanic-like eruption of inflammatory cellular exudate from the mucosal surface, is mainly attributed to Clostridium difficile toxins and often presents with symptomatic diarrhea. Rarely, there are case reports of similar pseudomembranous lesions limited to the stomach in the absence of intestinal involvement...

BACKGROUND: Reactive arthritis and septic arthritis rarely present concomitantly in the same joint and patient. Reactive arthritis presenting after coronavirus disease 2019 is also exceedingly rare, with less than 30 cases reported thus far. Less common pathogens such as Clostridium difficile have been reported to cause reactive arthritis, especially in patients with a positive human leukocyte antigen B27, and therefore should be considered in diagnostic algorithms. The aim of this case report is to highlight the difficulties and precautions in discerning and diagnosing patients presenting with sudden swelling of the knee...

BACKGROUND AND AIMS: The goal was to identify microbial drivers of IBD, by investigating mucosal-associated bacteria and their detrimental products in IBD patients. METHODS: We directly cultured bacterial communities from mucosal biopsies from pediatric gastrointestinal patients and examined for pathogenicity-associated traits. Upon identifying C. perfringens as toxigenic bacteria present in mucosal biopsies, we isolated strains and further characterized toxicity and prevalence...

BACKGROUND: Antibiotic-associated diarrhea is a condition reported in 5-35% of patients treated with antibiotics, especially in older patients with comorbidities. In most cases, antibiotic-associated diarrhea is not associated with serious complications, but it can prolong hospitalization and provoke Clostridium difficile infection. An important role in the prevention of antibiotic-associated diarrhea is carried out by some probiotic strains such as Lactobacillus GG or the yeast Saccharomyces boulardii that showed good efficacy and a significant reduction in antibiotic-associated diarrhea...

Background: It is generally accepted that shoes and floors are contaminated with pathogens including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and Clostridium difficile , yet correlation to clinical infection is not well established. Because floors and shoes are low-touch surfaces, these are considered non-critical surfaces for cleaning and disinfection. The purpose of this review is to assess peer-reviewed literature inclusive of floors and shoe soles as contributors to the dissemination of infectious pathogens within healthcare settings...

Clostridioides (formerly Clostridium) difficile is a major bacterial cause of post-antibiotic diarrhoea. The epidemiology of C. difficile infections (CDIs) has dramatically changed since the early 2000s, with an increasing incidence and severity across Europe. This trend is partly due to the emergence and rapid worldwide spread of the hypervirulent and epidemic PCR ribotype 027. Profiles of patients with CDI have also evolved, with description of community-acquired (CA) infections in patients with no traditional risk factors for CDI...

Helicobacter pylori infection is a prevalent global infection associated with several complications such as peptic ulcer, upper gastrointestinal bleeding, and stomach cancer. An imbalance in the gut microbiota composition or the relationship between the microbiota and the host may be implicated in the infection. To investigate this, we studied the intestinal microbiota of 50 newly infected adolescents with H. pylori compared with 50 age-matched and sex-matched healthy controls. The gut microbiota composition was assessed using real-time polymerase chain reaction (RT-PCR), and the fecal bacterial diversity and composition were compared between groups...

BACKGROUND: Most previous studies on Clostridium difficile infection (CDI) mainly focused on adults with underlying diseases or critical illnesses. However, the number of CDI cases in children has also significantly increased, especially the growth of community-acquired CDI, which has attracted attention. This study was conducted to examine the toxin gene characteristics and the risk factors associated with community-acquired CDI (CA-CDI) in children with diarrhea. METHODS: Children with diarrhea before admission or within 48 hours of hospitalization were included in the study...

Clostridium difficile ( Clostridioides difficile ) is a leading cause of nosocomial infections in hospitalized patients worldwide. Stool samples were collected from 112 inpatients admitted to different hospitals and were screened for C. difficile GDH + toxin A + B by immunoassay, and all positive samples by immunoassay were processed for molecular detection of C. difficile using the GeneXpert assay. C. difficile strains were detected in 12 (10.71%) out of 112 stool samples using the GDH + toxin A + B immunoassay method and toxigenic C...

INTRODUCTION: Postoperative (postop) management of pediatric perforated appendicitis varies significantly, and postop intra-abdominal abscesses (IAA) remain a significant issue. Between 2019 and 2020, our standardized protocol included routine postop labs after an appendectomy for perforated appendicitis. However, given the lack of predictive utility of these routine labs, we discontinued this practice in 2021. We hypothesize that discontinuing routine postop labs will not be associated with an increase in complication rates after an appendectomy for pediatric perforated appendicitis...

Fecal calprotectin (FCP) is used to monitor inflammatory bowel disease (IBD) activity and can also be elevated in gastrointestinal infections. Our study's objective was to quantify the relationship between FCP levels and lab-confirmed infections in people with and without IBD. We performed a cross-sectional study at a tertiary-care center of all encounters during which FCP and gastrointestinal pathogen polymerase-chain reaction (GI PCR) panel testings were conducted. Using non-parametric tests and quantile regression, we compared the FCP levels by IBD status and pathogen detection...

INTRODUCTION: Clostridium difficile is the most common cause of antibiotic-associated diarrhea and colitis. Several methods are available for the detection of C. difficile in stool samples. This study aimed to use glutamate dehydrogenase (GDH), toxin detection, culture and polymerase chain reaction (PCR) techniques for the diagnosis of this pathogen. METHODOLOGY: A total of 300 stool samples were collected from children with hospital acquired diarrhea (HA-D), community acquired diarrhea (CA-D), and hospitalized non-diarrheic children as control with ages ranging from 6 months to 6 years (mean 3...

BACKGROUND: The prevalence of Clostridium difficile infection (CDI) as a common complication among inflammatory bowel disease (IBD) has been reported to increase worldwide and has been associated with a poor IBD outcome. OBJECTIVES: In this study, our aim was to report on the prevalence of CDI among IBD vs. non-IBD patients in King Abdulaziz Medical City (KAMC). METHODS: This retrospective descriptive study was carried out between 2016 and 2020...
