Efficacy and tolerability of system isotretinoin and effect of this therapy on the quality of life of patients with severe and moderate acne

Background. The relationship between acne and depression is being actively studied by the medical community. Question is depression a restriction in prescribing or a side effect when using systemic isotretinoin remains controversial. Noteworthy is the presence in the scientific literature of data on the possible positive effect of adequately and timely prescribed acne therapy on the psychoemotional state of patients with this ailment. Aims. The aim of our study was to evaluate the effectiveness of therapy with systemic isotretinoin in patients with moderate and severe acne, to assess the effect of the therapy on the quality of life of patients, as well as the persistence of remission after the end of the course of therapy with systemic retinoid. Methods. We observed 32 patients with moderate and severe acne, the average age of patients was 24 years, the duration of the disease was on average 8 years. All patients underwent therapy with systemic isotretinoin at an average daily dose of 0.5-1.0 mg/kg until a cumulative dose of 120-150 mg/kg was reached. The effectiveness and tolerability of the therapy was assessed, as well as the quality of life of patients was assessed using the dermatological index of the quality of life (DQL), the dermatological akne index (DIA), the HADS scale (anxiety and depression scale). The indicators were assessed before the start of therapy, during therapy, at the end of the course of treatment with systemic isotretinoin, and also 12 months after the end of therapy. Results. 100% of patients achieved clinical remission as a result of treatment with systemic isotretinoin. Before starting therapy with systemic isotretinoin, the indices were as follows: DQL 18 (15-20), HADS 10 (7-16) and DIA 13 (6-15) scores. By the end of the therapy, the indices decreased to 1 (0-1), 2 (0-4) and 1 (0-1) points, respectively (p < 0.001). 12 months (year) after the end of therapy with systemic isotretinoin, the indices remained at zero or one level in all patients: DQL 1 (0-1), HADS 0 (0-1) and CIA 1 (0-1) points (p < 0.001). Conclusion. A causal relationship between the intake of systemic isotretinoin and the development of depression has not been established. Systemic isotretinoin therapy was effective in all patients (100%), was well tolerated and had a positive effect on the psychoemotional status of patients with acne. 12 months after the end of therapy with the drug Erase, stable remission of the disease was noted in all patients
