Insights
Probiotics show a positive effect on atopic dermatitis (AD) in children, particularly single-strain treatments. However, more high-quality studies are needed to confirm these findings for pediatric AD management.
Area of Science:
- Pediatric Dermatology
- Microbiome Research
- Clinical Trials
Background:
- Atopic dermatitis (AD) is a common childhood skin condition.
- Probiotics are being investigated as a potential treatment for AD.
- This study evaluates the efficacy of probiotics in pediatric AD.
Purpose of the Study:
- To assess the effectiveness of probiotic interventions in improving the SCORAD (Severity of Atopic Dermatitis) value in children with AD.
- To systematically review randomized controlled trials (RCTs) comparing probiotic treatment to placebo for pediatric AD.
Main Methods:
- Systematic literature search of multiple databases (PubMed, Embase, Scopus, etc.) for RCTs published between January 2010 and January 2023.
- Included studies focused on pediatric patients with AD, assessing SCORAD values.
- Risk of bias and certainty of evidence were evaluated using Cochrane ROB 2.0.
Main Results:
- Analysis of 9 RCTs with 1000 patients revealed no significant difference in dichotomous outcomes between probiotic and control groups (p=0.23).
- Meta-analysis of continuous variables showed a significant improvement in SCORAD values with probiotic treatment (p=0.002).
- Subgroup analyses indicated no statistically significant effect of age, treatment duration, or probiotic species on SCORAD values.
Conclusions:
- Current evidence suggests limited but positive effects of probiotics on pediatric AD, especially single-strain formulations.
- High-quality studies are required to validate these findings due to limitations in the quantity and quality of included research.
Background:
Atopic dermatitis (AD) is a prevailing skin disease in childhood. Several studies have appraised probiotics as a strategy for treating AD. We aimed to assess the validity of probiotics in the treatment of AD in children.
Methods:
We systematically searched the PubMed/MEDLINE, Embase, Scopus, EBSCO, Web of Science and Cochrane library databases for randomized controlled trials (RCTs) that assessed the effect of probiotic treatment on SCORAD value in pediatric patients with AD compared with a placebo group between 1 January 2010 and 1 January 2023. The risk of bias and the certainty of evidence were assessed using Cochrane ROB 2.0.
Results:
A total of 10 outcomes from 9 RCTs involving 1000 patients were included. Three of these outcomes were analyzed as dichotomous variables in 373 patients. The other seven were analyzed for continuous variables in 627 patients. A meta-analysis of the random-effect model of the dichotomous variables demonstrated no significant difference between the probiotic and control groups [OR = 1.75, 95% confidence interval (CI) (0.70, 4.35), p = 0.23, I2 = 68%]. A meta-analysis of the random-effect model of continuous variables demonstrated significant differences between the probiotic and control groups [MD = -4.24, 95% CI (-7.78, -0.71), p = 0.002, I2 = 71%]. Subgroup analysis of continuous variables showed that the effects of children's age, treatment duration and probiotic species on the SCORAD value were not statistically significant.
Conclusion:
Evidence on the improvement effect of probiotics on pediatric patients with AD is limited. This study showed that single-strain probiotic treatment exerts a positive effect on AD. Restricted to the quantity and quality of incorporated studies, these conclusions have yet to be validated by high-quality studies.
