Introduction: Dimethyl fumarate (DMF) is approved as oral systemic treatment for moderate-to-severe psoriasis. Scarce evidence is available for DMF treatment in psoriatic patients at the time of COVID-19 pandemic. The objective of this study was to assess the long-term effectiveness and safety of DMF monotherapy in moderate-to-severe psoriasis during the COVID-19 pandemic period. Methods: This multicenter, retrospective study included patients with moderate-to-severe psoriasis who had received a 48-week DMF treatment during the COVID-19 pandemic. Selected outcomes were: variation of mean PASI, proportion of patients achieving PASI50 and PASI75, variation of mean PGA and face PGA, genital PGA, scalp PGA, mean itch VAS and mean DLQI. Results: Forty-four patients were enrolled, and four patients became COVID-19 positive during the observation period but did not discontinue DMF therapy. DMF produced a significant improvement of signs and symptoms of psoriasis as expressed by mean PASI variation from 13.07 at baseline to 6.11 at week 48 (p < 0.0001), itch VAS from 3.22 at baseline to 1.18 at week 48 (p < 0.001), PGA from 2.84 at baseline to 1.30 at week 48 (p < 0.0001) and DLQI from 13.09 at baseline to 6.07 at week 48 (p < 0.0001). The percentage of patients who achieved PASI50 and PASI75 was 4.55% at week 4 and 59.09% at week 48 and 0% at week 4 and 22.73% at week 48, respectively. A clinical important decrease of mean PGA score was observed in all subgroups, face psoriasis, genital psoriasis and scalp psoriasis. Adverse events were predictable and manageable. Conclusions: DMF monotherapy is an effective and safe treatment option in moderate-to-severe psoriasis also in patients who develop SARS-CoV-2 infection.

Abstract

Introduction: Dimethyl fumarate (DMF) is approved as oral systemic treatment for moderate-to-severe psoriasis. Scarce evidence is available for DMF treatment in psoriatic patients at the time of COVID-19 pandemic. The objective of this study was to assess the long-term effectiveness and safety of DMF monotherapy in moderate-to-severe psoriasis during the COVID-19 pandemic period. Methods: This multicenter, retrospective study included patients with moderate-to-severe psoriasis who had received a 48-week DMF treatment during the COVID-19 pandemic. Selected outcomes were: variation of mean PASI, proportion of patients achieving PASI50 and PASI75, variation of mean PGA and face PGA, genital PGA, scalp PGA, mean itch VAS and mean DLQI. Results: Forty-four patients were enrolled, and four patients became COVID-19 positive during the observation period but did not discontinue DMF therapy. DMF produced a significant improvement of signs and symptoms of psoriasis as expressed by mean PASI variation from 13.07 at baseline to 6.11 at week 48 (p < 0.0001), itch VAS from 3.22 at baseline to 1.18 at week 48 (p < 0.001), PGA from 2.84 at baseline to 1.30 at week 48 (p < 0.0001) and DLQI from 13.09 at baseline to 6.07 at week 48 (p < 0.0001). The percentage of patients who achieved PASI50 and PASI75 was 4.55% at week 4 and 59.09% at week 48 and 0% at week 4 and 22.73% at week 48, respectively. A clinical important decrease of mean PGA score was observed in all subgroups, face psoriasis, genital psoriasis and scalp psoriasis. Adverse events were predictable and manageable. Conclusions: DMF monotherapy is an effective and safe treatment option in moderate-to-severe psoriasis also in patients who develop SARS-CoV-2 infection.
