This microbial imbalance is thought to contribute to the initiation and progression of the disease through mechanisms such as triggering abnormal immune responses, exacerbating inflammatory processes, and impairing the skin barrier.Read full original descriptionShow less
Evaluating the Safety and Efficacy of Lactobacillus Plantarum in Treating Psoriasis: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial
A growing body of evidence indicates that the pathogenesis of psoriasis may be closely linked to skin microbiome dysbiosis. Compared with healthy individuals, the composition and function of the skin microbiota in psoriasis patients exhibit significant alterations5,6. This microbial imbalance is thought to contribute to the initiation and progression of the disease through mechanisms such as triggering abnormal immune responses, exacerbating inflammatory processes, and impairing the skin barrier.
In-depth exploration of the interplay between psoriasis and the microbiome not only offers new perspectives for elucidating the disease's pathogenesis but also lays the groundwork for developing innovative microbiota-targeted diagnostic and therapeutic strategies. Thus, identifying novel therapeutic approaches that bridge psoriasis treatment and microbial regulation holds substantial clinical and social value.
While existing treatments for psoriasis have made some progress, research specifically focusing on the microbiota-psoriasis relationship remains relatively limited. Investigating the intrinsic connections between microecological balance and psoriasis management, and developing practical improvement strategies, is therefore of crucial practical significance for enhancing skin health and improving quality of life. This study aims to address this research gap and provide a new therapeutic option for individuals with psoriasis.
