Study of the effect of probiotics on the therapeutic effect obtained in the reduction of allergic symptoms in patients diagnosed with atopic dermatitis

Introduction: Atopic dermatitis (AD) is a chronic inflammatory skin disease posing a significant burden on healthcare resources and patients' quality of life. It is a complex disease with a wide spectrum of clinical presentations and combinations of symptoms. Atopic dermatitis affects up to 20% of children and up to 3% of adults. Recent data show that its prevalence is still increasing, especially in low-income countries. This study aimed to check whether the use of probiotic therapy affects the reduction of allergic symptoms in patients diagnosed with AD. Material and methods: Questionnaires of 70 respondents diagnosed with AD who took a probiotic for at least 5 days were analysed. To conduct the study, an anonymous, original survey was used in the form of a form created on Google Drive consisting of 19 questions with the possibility of answering both single and multiple choice and with the possibility of providing your own answer. Results: The most beneficial strains affecting the reduction of allergic symptoms are bacteria of the genus Lactobacillus . The average duration of use of probiotic therapy to reduce allergic symptoms is from 2 weeks to 3 months. Conclusions: The study showed that the implementation of probiotic therapy shortens the duration of therapy for AD and reduces allergic symptoms such as redness, itching of the skin and allergic rhinitis co-occurring in patients with AD.
