Abstract:
Background: Asthma is one of the most prevalent chronic diseases, affecting more than 300 million individuals globally. Inhaled corticosteroids (ICSs) are recommended as the primary therapy for managing and preventing asthma symptoms in current treatment guidelines. However, long-term use of ICSs could lead to multiple side effects, including skin changes. Methods: We identified ICS target genes using DrugBank and DGIdb databases and derived genetic instruments from cis-eQTL data in whole-blood samples (n = 31,684). GWAS data for facial aging traits (n = 423,999) and plasma metabolites (1400 metabolites, n = 8000) were analyzed. DNA methylation QTL (mQTL) data were used to explore epigenetic regulation. Mendelian randomization (MR) and colocalization analyses were performed to assess causality and shared genetic loci. Results: MR analysis suggested a significant link between genetically proxied ICSs (ORMDL3) and face aging in the European population. Further mediation analysis indicated that 5-Hydroxylysine partially mediates the relationship between ICSs and face aging. In addition, our analysis revealed the pleiotropic association of some novel DNA methylation sites of ORMDL3 with face aging, suggesting the possible regulatory mechanism that are involved in face aging. Conclusions: These findings, while exploratory, raise the hypothesis that ICSs may impact face aging through upregulation of ORMDL3 expression and 5-hydroxylysine metabolism and highlight the need for further pharmacological and clinical research to validate these potential effects.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
