Abstract
This study aimed to explore the potential causal relationships between rosacea and Parkinson’s disease, Alzheimer’s disease, anxiety disorders, and depression with MR analysis. Genetic data for rosacea and the four neurodegenerative and neuropsychiatric disorders were sourced from GWAS databases. After completing stringent quality control procedures, SNPs meeting significance thresholds were selected as IVs. Our primary statistical analysis was conducted by IVW approach. To investigate the robustness of results, heterogeneity tests, sensitivity analyses, and pleiotropy assessments were conducted. Reverse MR analyses were subsequently carried out to further substantiate the causal relationships. The present study discovered a positive correlation between rosacea and an elevated risk of depression (OR = 1.0015, 95% CI = 1.0002–1.0027, P = 0.02). There is no causal evidence to support a connection between rosacea and Parkinson’s disease, Alzheimer’s disease, or anxiety disorders. Reverse MR analyses indicated no causal associations between these four disorders and the risk of rosacea. The findings reveal that individuals with rosacea may have an elevated risk of depression.
期刊介绍:
Archives of Dermatological Research is a highly rated international journal that publishes original contributions in the field of experimental dermatology, including papers on biochemistry, morphology and immunology of the skin. The journal is among the few not related to dermatological associations or belonging to respective societies which guarantees complete independence. This English-language journal also offers a platform for review articles in areas of interest for dermatologists and for publication of innovative clinical trials.
