Infectious diarrhea

Abdel-Naser Elzouki
Probiotics are live, nonpathogenic bacteria capable of colonizing the colonic mucosa. The most common probiotics include strains of Lactobacillus or Bifidobacteria, which are part of the normal gastrointestinal microbiota. Initial studies of selected probiotic species have suggested potential efficacy in several gastrointestinal diseases including inflammatory bowel diseases (particularly pouchitis), antibiotic-related diarrhea, Clostridium difficile toxin-induced colitis, infectious diarrhea, irritable bowel syndrome, and allergy...

Cases of Aeromonas diarrhea have been described all over the world. The genus Aeromonas includes ca. 30 species, of which 10 have been isolated in association with gastroenteritis. The dominating species that account for ca. 96% of the identified strains are Aeromonas caviae, A. veronii, A. dhakensis, and A. hydrophila. However, the role of Aeromonas as a true enteropathogen has been questioned on the basis of the lack of outbreaks, the non-fulfillment of Koch's postulates and the low numbers of acute illnesses in the only existing human challenge study...

ETHNOPHARMACOLOGICAL RELEVANCE: Andrographis paniculata is included in 'The National List of Essential Herbal Drugs A.D. 1999' of Thailand as an herbal drug for the treatment of common cold symptoms and non-infectious diarrhea. The therapeutic activities of A. paniculata are attributed to four major active diterpenoids: andrographolide (1), 14-deoxy-11, 12-didehydroandrographolide (2), neoandrographolide (3), and 14-deoxyandrographolide (4). However, the pharmacokinetic studies in humans of this plant were performed after a single oral dose administration and reported the parameters related to be of only 1...

BACKGROUND: The 2014 outbreak of Ebola virus disease (EVD) in West Africa was the largest ever recorded. Starting in September 2014, International Medical Corps (IMC) managed 5 Ebola treatment units (ETUs) in Liberia and Sierra Leone, which cumulatively cared for about 2,500 patients. We conducted a retrospective cohort study of patient data collected at the 5 ETUs over 1 year of operations. METHODS: To collect clinical and epidemiological data from the patient care areas, each chart was either manually copied across the fence between the high-risk zone and low-risk zone, imaged across the fence, or imaged in the high-risk zone...

Diarrhea is a common complication in solid organ transplant (SOT) recipients and may be attributed to immunosuppressive drugs or infectious organisms such as bacteria, viruses or parasites. Cryptosporidium usually causes self-limited diarrhea in immunocompetent hosts. Although it is estimated that cryptosporidium is involved in about 12% of cases of infectious diarrhea in developing countries and causes approximately 748000 cases each year in the United States, it is still an under recognized and important cause of infectious diarrhea in SOT recipients...

INTRODUCTION: Circulating anti-CdtB/anti-vinculin antibodies have been validated as biomarkers to distinguish IBS-D from IBD, but there is no experience with them in Latin America. MATERIALS AND METHODS: The analysis was carried out on patients seen at a FGIDs/motility clinic over the last 7 months for diarrhea with abdominal pain and/or bloating who were tested for these antibodies. The patients were diagnosed according to the Rome III criteria or with organic disorders, and those presenting with IBS were further classified as post-infectious (PI) or non-PI IBS...

BACKGROUND Clostridium difficile is the principal infectious cause of antibiotic-associated diarrhea and accounts for 12% of hospital-acquired infections. Recent literature has shown an increased risk of C. difficile infection (CDI) with proton pump inhibitor (PPI) use. OBJECTIVE To conduct a systematic assessment of the risk of hospital-acquired CDI following exposure to PPI. METHODS We searched multiple databases for studies examining the relationship between PPI and hospital-acquired CDI. Pooled odds ratios were generated and assessment for heterogeneity performed...

Vibrio cholerae is the etiological agent of the infectious disease cholera, which is characterized by vomiting and severe watery diarrhea. Recently, V. cholerae clinical isolates have demonstrated increased virulence capabilities, causing more severe symptoms with a much higher rate of disease progression than previously observed. We have identified single nucleotide polymorphisms (SNPs) in four virulence-regulatory genes (hapR, hns, luxO, and vieA) of a hypervirulent V. cholerae clinical isolate, MQ1795...

Chronic, non-infectious diarrhea can be caused by a variety of gastrointestinal diseases. In anamnesis, it is important to take accompanying warning symptoms and specific triggers into account. The fecal inflammatory marker calprotectin may help differentiating between organic and functional gastrointestinal disorders, but it is not specific. Among other options, gelling fibres, Loperamide and Cholestyramine as well as probiotics are available for the symptomatic treatment of chronic diarrhea. For long-term treatment of chronic diarrhea with the enkephalinase inhibitor racecadotril, which is approved for acute diarrhea, only limited data are available...

Impaired absorption of electrolytes is a hallmark of diarrhea associated with inflammation or enteric infections. Intestinal epithelial luminal membrane NHE3 (Na(+)/H(+) exchanger 3) and DRA (Cl(-)/HCO3 (-) exchanger) play key roles in mediating electroneutral NaCl absorption. We have previously shown decreased NHE3 and DRA function in response to short-term infection with enteropathogenic E. coli (EPEC), a diarrheal pathogen. Recent studies have also shown substantial downregulation of DRA expression in diarrheal model of infection with Citrobacter rodentium, the mouse counterpart of EPEC...

The strict anaerobe Clostridium difficile is the most common cause of nosocomial diarrhea, and the oxygen-resistant spores that it forms have a central role in the infectious cycle. The late stages of sporulation require the mother cell regulatory protein σK. In Bacillus subtilis, the onset of σK activity requires both excision of a prophage-like element (skinBs) inserted in the sigK gene and proteolytical removal of an inhibitory pro-sequence. Importantly, the rearrangement is restricted to the mother cell because the skinBs recombinase is produced specifically in this cell...

BACKGROUND: Campylobacter jejuni causes diarrhea worldwide; young children are most susceptible. Binding of virulent C. jejuni to the intestinal mucosa is inhibited ex vivo by α1,2-fucosylated carbohydrate moieties, including human milk oligosaccharides (HMOSs). OBJECTIVE: The simplest α1,2-fucosylated HMOS structure, 2'-fucosyllactose (2'-FL), can be predominant at ≤5 g/L milk. Although 2'-FL inhibits C. jejuni binding ex vivo and in vivo, the effects of 2'FL on the cell invasion central to C...
