Possibilities of using topical retinoids and azelaic acid in acne therapy

Abstract

Background. Acne is a common, complex and multifactorial inflammatory disease that results from a variety of causes. Acne therapy is an urgent problem of dermatocosmetology. The clinical manifestations of dermatosis can be alleviated, and its long-term consequences can be prevented by early diagnosis and timely initiation of treatment, affecting multifaceted all parts of the pathogenesis.
 Aims. To evaluate the clinical efficacy and safety of the use of monotherapy of 0.1% adapalene cream (Adaclean) with combined external therapy of 0.1% adapalene cream (Adaclean) with 20% azelaic acid cream (Azix-Derm) in the treatment of mild to moderate acne.
 Methods. Under our supervision at the Department of Plastic Reconstructive Surgery, Cosmetology and Regenerative Medicine of the State Budgetary Educational Institution of Higher Professional Education Rost of the State Medical University of the Ministry of Health of Russia, the clinics “Ekaterininskaya” and “MIR-O-MED” there were 50 patients aged 12 to 50 years (18 (36%) men and 32 (64%) women) with mild and moderate acne. Patients with comedonal acne, in the absence of multiple inflammatory elements, which made up group 1 of observation (n = 16), were prescribed Adaclean cream, 1 time per day (evening) against the background of skin care. In the group with mild to moderate papulo-pustular acne and post-inflammatory changes (group 2, n = 34), patients were prescribed a combination of 0.1% adapalene cream and 20% azelaic acid cream (Adaclean (evening) and Azix-Derm (morning)). The follow-up period was 6 months.
 Results. Total clinical remission after 6 months therapy was achieved in 70% of cases, a significant improvement — in 28%, improvement — in 2%. In patients with a comedonal form of acne against the background of monotherapy with Adaclean cream, clinical recovery was obtained in 44% of patients, a significant improvement — in 50%, and an improvement — in 6%. In patients from the group of papulo-pustular acne of mild to moderate severity, after 3 months the use of complex therapy Adaclean and Azix-Derm noted almost complete relief of the inflammatory process; after 6 months therapy clinical recovery was recorded in 58%, significant improvement — in 36%; 6% showed partial improvement, which is associated with irregular use of drugs and skin care products. After 6 months combined treatment was able to achieve regression of dyschromia in 18–46% of patients, atrophic scars — in 5–22%, which significantly improved the results of therapy and made it possible to achieve a good cosmetic effect.
 Conclusion. The combined use of drugs for external use of adapalene (Adaclean) and AK (Azix-Derm) in the treatment of papulo-pustular acne of mild and AK (Azix-Derm) in the treatment of papulo-pustular acne of mild and moderate severity can significantly increase the effectiveness of treatment, achieve a stable clinical effect and remission of the disease, as well as improve the quality of life of patients.
