Objective: To explore the effect of topical cannabidiol (CBD) in treating digital ulcers in patients with systemic sclerosis (SSc)., Methods: In total, 45 patients with SSc who had digital ulcers were consecutively enrolled between January 2019 and December 2019. Of the participants, 25 were treated with CBD during surgical debridement and 20 were treated with standard local therapy. A numeric rating scale for pain and Health Assessment Questionnaire Disability Index were administered at the baseline and at the end of treatment., Results: Local treatment with CBD was significantly associated with lower pain scores, higher health assessment scores, and an increase in participants' total hours of sleep. Patients in the control group more frequently required additional analgesic therapy., Conclusions: Topical CBD may be a valuable tool to treat pain related to digital ulcers in patients with SSc., (Copyright © 2022 the Author(s).

Abstract: During the last years there has been an increasing availability of drugs (biologics and small molecules) with different mechanisms of action (MoA) in psoriatic arthritis (PsA). New issues about treatment strategies have arisen. The main aim of this study is to verify if there is a difference in terms of clinical efficacy (i.e. retention rate) between cycling (i.e. treating patients with the same MoA after the failure of the previous one) or swap (i.e choosing drugs with a MoA different from the failed previous one) strategies in PsA.In this mono-centric medical records review study, PsA patients treated with biologics, apremilast or tofacitinib were enrolled. Every prescription was clustered in three groups: cycling (CG), swap (SG) or first line group (1LG). Kaplan-Meier analysis and Cox test estimated and compared drugs' retention rate in CG, SG and 1LG. P < .05 was considered statistically significant.One hundred eighty-three PsA patients were enrolled (9967 patient-months). In CG and 1LG the more prescribed drugs were tumor necrosis factor inhibitor (respectively 99% and 89%), in SG interleukin 17 inhibitor (60%). There were no differences in terms of sex, age, disease duration, and retention rate between CG and SG. The 18-months retention rate of 1LG, SG and CG was 77%, 60%, and 51% respectively. The CG retention rate was lower than in 1LG (P = .03).The findings of this study suggest that in PsA the swap strategy gives no remarkable advantage compared to cycling. However, patients undergoing swap strategy may experience the same failure rate observed in naives., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2021 the Author(s).
