Risk factors for the development of Clostridium difficile toxin-associated diarrhoea: a pilot study
Pharmacoepidemiology and Drug Safety
|January 5, 2002
Summary
Certain antibiotics like cephalosporins and erythromycin increase the risk of developing Clostridium difficile toxin-associated diarrhea. This pilot study identified key risk factors for this common hospital-acquired infection.
Area of Science:
- Infectious Diseases
- Microbiology
- Clinical Pharmacy
Background:
- Clostridium difficile toxin-associated diarrhea is a significant healthcare-associated infection.
- Antimicrobial agents are a known risk factor, but specific drug influences require further investigation.
Purpose of the Study:
- To investigate risk factors for Clostridium difficile toxin-associated diarrhea.
- To determine the differential influence of various antimicrobial agents on disease development.
Main Methods:
- Retrospective case-control study design.
- Inclusion of inpatient cases with stool-positive C. difficile toxin diarrhea.
- Matching of two controls per case based on age and admission type.
- Conditional logistic regression analysis for risk factor identification.
Main Results:
- Cephalosporins were identified as a statistically significant risk factor.
- Erythromycin was also found to be significantly associated with the condition.
- These findings highlight specific antibiotic classes linked to C. difficile infections.
Conclusions:
- Pilot study successfully identified key antimicrobial risk factors.
- Results support the need for a larger, prospective study to confirm findings.
- Informs antibiotic stewardship and infection control strategies.

01:26Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

01:18Dysbiosis of the Gut Microbiota
The human gut microbiome includes a diverse array of microbial species, including beneficial commensals and opportunistic pathogens, which interact to support host health. These microbes contribute to essential functions such as nutrient metabolism, immune system modulation, and maintenance of intestinal barrier integrity. However, disruptions to this equilibrium—referred to as dysbiosis—can have widespread physiological consequences.Dysbiosis is often characterized by reduced microbial...
01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
01:12Bacterial Toxins
Bacterial toxins are sophisticated virulence factors that enable pathogenic bacteria to interact with, invade, and damage host tissues. These toxins fall broadly into two types: protein exotoxins, which are secreted into the environment and target specific host receptors, and lipopolysaccharide endotoxins, which are structural components of the bacterial outer membrane released primarily during bacterial lysis or membrane shedding. Exotoxins generally act more selectively, binding to cell...
01:18Bacterial Gastroenteritis
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
