Insights
Persistent White Blood Cell (WBC) excretion in infants with allergic proctocolitis did not impact weight gain in the first year. This finding suggests inflammatory stool markers may have limited predictive value for impaired growth in these children.
Area of Science:
- Pediatric Gastroenterology
- Allergy and Immunology
- Clinical Nutrition
Background:
- Allergic proctocolitis in infants can manifest as impaired weight gain and failure to thrive.
- The association between White Blood Cell (WBC) excretion and subsequent weight gain after complementary feeding in allergic proctocolitis is not well understood.
Purpose of the Study:
- To investigate whether persistent WBC excretion in infants with allergic proctocolitis is associated with impaired weight gain during the first year of life.
Main Methods:
- A prospective cohort study followed 85 children with allergic proctocolitis from birth to 1 year.
- Weight gain and WBC excretion were monitored, comparing infants with and without persistent excretion.
- Data were analyzed using SPSS statistical software.
Main Results:
- Persistent WBC excretion was more common in boys (p=0.023) but did not differ significantly in age distribution (p=0.35).
- No significant difference in standardized weight changes was observed between infants with and without persistent WBC excretion (p >0.05).
Conclusions:
- Persistent leukocyte excretion in allergic proctocolitis does not appear to negatively affect infant weight gain.
- Inflammatory stool markers may have limited predictive value for growth impairment in allergic proctocolitis.
- Further research with larger cohorts and refined biomarkers is needed to understand long-term implications.
Introduction/Objective:
In children affected by allergic proctocolitis, impaired weight gain and developmental failure to thrive can be a prominent manifestation. However, it remains unclear whether the association between White Blood Cell (WBC) excretion in these patients and the occurrence of food allergies is associated with subsequent impaired weight gain after the start of complementary feeding.
Materials And Methods:
In this prospective cohort study, 85 children with allergic proctocolitis were followed from birth to 1 year of age regarding continued WBC excretion, weight gain, and the presence or absence of allergic symptoms. Also, the weight gain of children was examined and compared between those with continued leukocyte excretion and those without. Data were analyzed using SPSS statistical software version 26.
Results:
The age distribution of infants in the two groups with and without persistent WBC excretion did not differ significantly (p =0.35). However, the gender distribution was significantly different, with persistent excretion higher in boys (p =0.023). Examination of standardized weight changes showed no significant difference between the two groups, with and without persistent WBC excretion (p >0.05).
Discussion:
Persistent leukocyte excretion did not affect weight gain, consistent with reports that inflammatory stool markers have limited predictive value in allergic proctocolitis. Future studies with larger samples and refined inflammatory biomarkers are needed to clarify the clinical significance and potential long-term allergic implications of persistent intestinal inflammation.
Conclusion:
Persistent WBC excretion in children with allergic proctocolitis was observed in some of the patients, but was not associated with impaired weight gain during the first year of life.

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...
