Study of Skin Microbiome in Patients With Alopecia Areata: Case Control Study

This study investigated the skin microbiome in 50 Egyptian subjects, including 25 patients with alopecia areata (AA) and 25 healthy controls. The research found no significant difference in Staphylococcus epidermidis gene expression between AA patients and healthy subjects. However, there was a significant negative correlation between the relative gene expression of Staphylococcus epidermidis and the SALT score, suggesting that changes in the skin microbiome, particularly the expression of Staphylococcus epidermidis, may be linked to the severity of alopecia areata. This indicates that targeting the 16S region of Staphylococcus epidermidis could potentially help assess AA severity.
