Serum level of interleukin-15 in active alopecia areata patients and its relation to age, sex, and disease severity.

Introduction: Autoimmune mechanisms with evident genetic background are the main components of alopecia areata (AA) pathogenesis. Interleukin 15 (IL-15) is considered as an important signalling cytokine. Its disordered expression has been linked to inflammatory autoimmune disorders.

The effect of continuous high versus low dose oral isotretinoin regimens on dermcidin expression in patients with moderate to severe acne vulgaris.

The continuous low dose (LD) isotretinoin is frequently used in the treatment regimen for acne vulgaris. However, data about its antimicrobial are lacking. The present study aimed to investigate dermcidin expression and the effects of low and conventional dose isotretinoin on its expression in acne vulgaris patients.
