Antibiotic use, vitamin A deficiency, malnutrition, and lower respiratory infection (LRI) are key risk factors for persistent diarrhea (PD) in children. Identifying these factors can help reduce mortality from this condition.
Area of Science:
- Pediatrics
- Infectious Diseases
- Nutritional Science
Background:
- Persistent diarrhea (PD) is a significant cause of childhood morbidity and mortality globally.
- Identifying specific risk factors is crucial for effective prevention and management strategies.
Purpose of the Study:
- To determine risk factors associated with persistent diarrhea (PD).
- To identify risk factors contributing to deaths caused by PD.
Main Methods:
- A prospective case-control study involving 60 children with PD and 60 with acute diarrhea (AD).
- Data collected through detailed history, examination, and investigations.
- Statistical analysis included univariate and multivariate logistic regression to calculate Odds Ratios.
Main Results:
- Univariate analysis identified antibiotic use, steroid use, anemia, vitamin A deficiency, malnutrition, LRI, UTI, oral candidiasis, and hyponatremia as significant risk factors for PD.
- Multivariate analysis revealed prior antibiotic use, vitamin A deficiency, malnutrition, and LRI as independent predictors of PD.
- Mortality risk factors included frequent stools (>10/day), severe malnutrition, oral candidiasis, hypoalbuminemia, and HIV positivity.
Conclusions:
- Clinicians should be aware of identified risk factors to implement timely interventions.
- Early recognition and management of these risk factors can potentially decrease mortality associated with persistent diarrhea.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
Drugs for Treatment of Diarrhea-Predominant IBS
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...
