Insights
Probiotics significantly improved stool frequency and consistency in constipated children after four weeks. Early improvements in incontinence and pain were noted but not sustained long-term.
Area of Science:
- Pediatric Gastroenterology
- Microbiome Research
Background:
- Existing research on probiotics for childhood constipation yields inconsistent results.
- This study addresses the need for clearer evidence on probiotic efficacy.
Purpose of the Study:
- To evaluate the effectiveness of probiotics as an adjunct therapy for constipation in children.
- To compare outcomes in children receiving lactulose plus probiotics versus lactulose plus placebo.
Main Methods:
- A randomized, placebo-controlled trial involving 56 children aged 4-12 years with constipation.
- Participants received daily lactulose with either Protexin (probiotic) or placebo for four weeks.
- Outcomes measured included stool frequency, consistency, abdominal pain, fecal incontinence, and weight gain.
Main Results:
- Forty-eight children completed the study.
- Significant improvements in stool frequency (P=0.042) and consistency (P=0.049) were observed by week four.
- Early improvements in fecal incontinence (P=0.030) and abdominal pain (P=0.017) at week one were not significant by week four.
- Significant weight gain was noted by week one in the probiotic group.
Conclusions:
- Probiotics play a beneficial role in enhancing stool frequency and consistency in constipated children by the end of a four-week treatment period.
- While short-term symptom relief was observed, long-term benefits require further investigation.
Abstract:
Background. Inconsistent data exist about the role of probiotics in the treatment of constipated children. The aim of this study was to investigate the effectiveness of probiotics in childhood constipation. Materials and Methods. In this placebo controlled trial, fifty-six children aged 4-12 years with constipation received randomly lactulose plus Protexin or lactulose plus placebo daily for four weeks. Stool frequency and consistency, abdominal pain, fecal incontinence, and weight gain were studied at the beginning, after the first week, and at the end of the 4th week in both groups. Results. Forty-eight patients completed the study. At the end of the fourth week, the frequency and consistency of defecation improved significantly (P = 0.042 and P = 0.049, resp.). At the end of the first week, fecal incontinence and abdominal pain improved significantly in intervention group (P = 0.030 and P = 0.017, resp.) but, at the end of the fourth week, this difference was not significant (P = 0.125 and P = 0.161, resp.). A significant weight gain was observed at the end of the 1st week in the treatment group. Conclusion. This study showed that probiotics had a positive role in increasing the frequency and improving the consistency at the end of 4th week.
