Insights
Tropheryma whipplei was detected in Iranian children with acute diarrhea, suggesting its role in the condition. This finding highlights the need for healthcare awareness regarding T. whipplei infections in childhood diarrhea.
Area of Science:
- Microbiology
- Pediatrics
- Infectious Diseases
Background:
- Tropheryma whipplei is a suspected cause of childhood diarrhea globally.
- Data on T. whipplei prevalence in Iranian children with diarrhea is limited.
- This study investigated T. whipplei in children experiencing acute diarrhea in Iran.
Purpose of the Study:
- To determine the prevalence of Tropheryma whipplei in children with acute diarrhea in Iran.
- To assess the association between T. whipplei and the duration of diarrhea in pediatric patients.
Main Methods:
- Stool samples were collected from 130 children under 10 years old with acute diarrhea in Tehran.
- Genomic DNA was extracted and tested for T. whipplei using SYBR Green Real-time PCR.
- Positive samples were confirmed by PCR product sequencing.
Main Results:
- Tropheryma whipplei DNA was detected in 9.23% (12/130) of the stool samples.
- Diarrhea duration was significantly longer in T. whipplei-positive children (83.3%) compared to negative cases (45.8%).
- No significant association was found between T. whipplei infection and other demographic factors or clinical signs.
Conclusions:
- Tropheryma whipplei was identified in children with acute diarrhea in Iran.
- The findings suggest T. whipplei may be associated with childhood diarrhea in the region.
- Healthcare providers should consider T. whipplei in the differential diagnosis of childhood diarrhea in Iran.
Background:
Recently, Tropheryma whipplei has been suggested as one of the causative agents of diarrhea among children worldwide. Limited data is available on the prevalence of T. whipplei among children with diarrhea in most countries such as Iran. This study was conducted to evaluate the prevalence of T. whipplei in children with acute diarrhea in Iran.
Methods:
In this study, the stool samples were collected from 130 children under 10 years old with acute diarrhea from children's hospitals in Tehran city. Genomic DNA was extracted from stool samples and was tested for the presence of DNA of T. whipplei using the SYBR Green Real-time PCR method. Positive T. whipplei samples were finally confirmed by PCR Product sequencing.
Results:
The mean age of participants was 32.5 months, and 54.6% of children were female. Using the SYBR Green Real-time PCR, 9.23% (12/130) of samples were positive for T. whipplei, which were confirmed by sequencing. 66.67% of positive cases were males. The duration of diarrhea in infected children with T. whipplei (83.3%) was significantly longer (OR: 5.93, 95% CI 1.24-28.22) compared to children with negative results (45.8%). Other demographic factors and clinical signs had not a statistically significant relationship with T. whipplei infection.
Conclusions:
In this study, T. whipplei was detected in stool samples of children with acute diarrhea. The results indicated that T. whipplei could be associated with childhood diarrhea in Iran. The health care system and physicians should be aware of the presence of T. whipplei infection in Iran, especially in childhood diarrhea.

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.
