Opis: Probiotics are known for their positive effects on the gut microbiota. There is growing evidence that the infant gut and skin colonization have a role in the development of the immune system, which may be helpful in the prevention and treatment of atopic dermatitis. This systematic review focused on evaluating the effect of single-strain probiotic lactobacilli consumption on treating children's atopic dermatitis. Seventeen randomized placebo-controlled trials with the primary outcome of the Scoring Atopic Dermatitis (SCORAD) index were included in the systematic review. Clinical trials using single-strain lactobacilli were included. The search was conducted until October 2022 using PubMed, ScienceDirect, Web of Science, Cochrane library and manual searches. The Joanna Briggs Institute appraisal tool was used to assess the quality of the included studies. Meta-analyses and sub meta-analyses were performed using Cochrane Collaboration methodology. Due to different methods of reporting the SCORAD index, only 14 clinical trials with 1124 children were included in the meta-analysis (574 in the single-strain probiotic lactobacilli group and 550 in the placebo group) and showed that single-strain probiotic lactobacilli statistically significantly reduced the SCORAD index compared to the placebo in children with atopic dermatitis (mean difference [MD]: -4.50; 95% confidence interval [CI]: -7.50 to -1.49; Z = 2.93; p = 0.003; heterogeneity I-2 = 90%). The subgroup meta-analysis showed that strains of Limosilactobacillus fermentum were significantly more effective than strains of Lactiplantibacillus plantarum, Lacticaseibacillus paracasei or Lacticaseibacillus rhamnosus. A longer treatment time and younger treatment age statistically significantly reduced symptoms of atopic dermatitis. The result of this systematic review and meta-analysis shows that certain single-strain probiotic lactobacilli are more successful than others in reducing atopic dermatitis severity in children. Therefore, careful consideration to strain selection, treatment time and the age of the treated patients are important factors in enhancing the effectiveness of reducing atopic dermatitis in children when choosing probiotic single-strain lactobacilli.

The impact of comorbidities on the severity of atopic dermatitis in children
Vojko Berce, Teja Marhold, Vid Delopst, 2022, izvirni znanstveni članek

Opis: Introduction: Atopic dermatitis (AD) is a chronic pruritic inflammatory skin disease. It is associated with atopy, impaired skin barrier, skin infections and several other comorbidities. Aim: To identify comorbidities and risk factors that influence the severity of AD in children. Material and methods: We performed a cross-sectional study involving 52 children newly diagnosed with AD. The severity of AD was assessed with the SCORing Atopic Dermatitis (SCORAD) clinical tool. Levels of serum tryptase, zinc, selenium, and immunoglobulins A, G, M and E (IgA, IgG, IgM, and total IgE, respectively) were determined as well as allergen-specific E antibodies (IgE) to the most common allergens. DNA samples from venous blood were screened for the most common mutations in the filaggrin gene. Results: The median age of patients was 30 months. The median SCORAD index in patients with atopy was 47.8, compared to 27.2 in non-atopic patients (p < 0.01). We also found a significantly higher median SCORAD of 61.2 in patients with low serum IgM levels compared to 34.9 in patients with normal serum IgM levels (p = 0.03). A history of impetigo was also associated with a higher median SCORAD of 56.2 compared to 34.0 in patients without impetigo (p = 0.01). Conclusions: Patients with AD and sensitisation to common allergens, low levels of IgM or a history of impetigo are at risk for more severe disease and, therefore, need more attention, meticulous skin care, proactive management and treatment of comorbidities, when possible.
