Infestation with Demodex mites was significantly more common in patients with rosacea compared with healthy controls, based on data from a meta-analysis of 1,513 adults with rosacea. The findings were published in the September issue of the Journal of the American Academy of Dermatology.
The cause of rosacea remains unclear and differs within subgroups, but previous studies have suggested an association between rosacea and the presence of Demodex mites, wrote Yin-Shuo Chang, MD, and Yu-Chen Huang, MD, both of Taipei Medical University, Taiwan (J Am Acad Dermatol. 2017; 77[3]:441-7).
