Comparative evaluation of therapy results in mild acne

Abstract

Introduction. Mild acne is the most underestimated form of the disease.The aim of the study was to compare the results of external combination therapy with 15% azelaic acid gel + 1% clindamycin gel and benzoyl peroxide + clindamycin for mild papulopustular acne.Material and methods. An open comparative prospective observational study in parallel groups (12 weeks) included 96 people, 65 patients with mild papulo-pustular acne and a control group of 30 healthy individuals. Group I received 15% azelaic acid gel +1% clindamycin gel, group II – benzoyl peroxide gel + clindamycin. The number of acne elements, morphofunctional indicators of the facial skin, side effects were recorded.Results. As a result of treatment, the indicators of sebumetry significantly decreased: in group I in the T-zone 47.5 ± 11.3 units (p = 0.043) and in the U-zone 57.5 ± 6.3 units (p = 0.037), and in group II in the T-zone 37.1 ± 5.8 units (p = 0.015) and in the U-zone 48.7 ± 5.6 units (p = 0.027). The pore sizes decreased significantly: in group I in the T-zone 0.052 ± 0.010 mm (p = 0.046) and in the U-zone 0.054 ± 0.009 mm (p = 0.049), and in group II in the T-zone 0.039 ± 0.011 mm (p = 0.064) and in the U-zone 0.047 ± 0.013 mm (p = 0.041). In patients in group I, pigmentation indicators in the T-zone of 17.0 ± 2.8 units (p < 0.001) and the U-zone of 17.0 ± 2.8 units (p = 0.048) were normalized. In patients in both groups, there was a significant (p >< 0.05) decrease in the number of papulopustules.>˂ 0.001) and the U-zone of 17.0 ± 2.8 units (p = 0.048) were normalized. In patients in both groups, there was a significant (p ˂ 0.05) decrease in the number of papulopustules.Conclusion. When comparing the results of therapy with 15% azelaic acid gel + 1% clindamycin gel and benzoyl peroxide + adapalene for mild papulopustular acne, comparable efficacy and safety were revealed.
