Serum survivin in acne versus post-acne scarring and the possible effect of isotretinoin therapy on its level.

INTRODUCTION Acne vulgaris is a common chronic inflammatory disorder of the pilosebaceous unit. Survivin is an apoptosis inhibitor protein, and it contributes crucially to cell cycle regulation. This study measures the serum level of survivin in acne and post-acne scarring patients, and assesses the possible effect of isotretinoin therapy on its level. METHODS Sixty participants, including 40 acne patients (Group IA, IB), and 20 age- and sex-matched controls (Group II) were included. Group IA included 20 patients with active moderate-to-severe acne without scarring, and this group was further prescribed oral isotretinoin therapy for 3 months. Group IB included 20 patients with post-acne scarring of a duration not more than 6 months, without evident active acne lesions. Serum survivin levels were measured in the three groups using an enzyme-linked immunosorbent assay. RESULTS There was a statistically significant higher serum survivin level in the acne scar group, followed by the active acne group, than in controls. In addition, there was a statistically significant reduction in survivin levels after treatment, and it was positively correlated with a reduction in the global acne grading system (GAGS) in the active acne group. CONCLUSIONS Survivin may play a role in the evolution of acne and acne scarring, and it could be a possible target for isotretinoin therapy.
