Effect of synbiotic supplementation on children with atopic dermatitis: an observational prospective study.
The objective of this observational single-cohort prospective study was to assess the effect of synbiotic supplementation for 8 weeks in children with atopic dermatitis (AD). The synbiotic product contained Lactobacillus casei, Bifidobacterium lactis, Lactobacillus rhamnosus, Lactobacillus plantarum, fructooligosaccharide, galactooligosaccharide, and biotin. Patients were examined at baseline and at 8 weeks. Effectiveness of treatment was assessed with the Scoring Atopic Dermatitis (SCORAD) index. A total of 320 children (mean age 5.1 years, range 0-12 years) were included. The mean (SD) SCORAD index decreased from 45.5 (15.5) at baseline to 19.4 (14.6) at the end of treatment (P < 0.001), VAS score for pruritus decreased from 5.7 (2.2) to 2.3 (2.2) (P < 0.001), and VAS score for sleep decreased from 3.1 (2.5) to 1.1 (1.8) (P < 0.001). Percentage of children with moderate-severe disease decreased from 92.4% at baseline to 28.1% at week 8. In the multiple linear regression analysis, higher baseline SCORAD index (OR 0.51; 95% CI 0.41-0.61) and higher adherence (OR 7.29; 95% CI 1.85-12.73) were significantly associated with greater decrease in SCORAD index.
Supplementation with the multistrain synbiotic product may improve AD in children. What is known: • Pediatric atopic dermatitis (AD) is a common, troublesome condition with limited treatment options, which has been shown to be associated with dysbiosis in the intestinal microflora. • Results of controlled clinical trials (RCTs) on the effect of probiotics in children with AD have been disparate, although overall, the data favor probiotics over placebo, with multistrain supplements associated with better improvements in AD. What is new: • The results of this observational, prospective, open-label, single-cohort study on 320 children with AD younger than 12 years old suggest that supplementation with multistrain synbiotics (Lactobacillus casei, Bifidobacterium lactis, Lactobacillus rhamnosus, Lactobacillus plantarum, fructooligosaccharide, galactooligosaccharide, and biotin) helps to improve AD symptoms in children. • More than 80% of children experienced improvement in AD symptoms, as measured by Severity Scoring of Atopic Dermatitis (SCORAD) index and assessed by parents and physicians. The main predictive factors for improvement was adherence to synbiotic treatment and high baseline SCORE index; the change in SCORAD did not depend on age, gender, presence of concomitant treatment, duration, and type of AD (persistent vs with flares), other concomitant allergies or history of parental allergy.
