Topal IO, Polat AK, Zindancı I, et al. - The rates of adherence to systemic treatments were determined in patients with psoriasis during the COVID-19 pandemic. In addition, the causes of non-adherence were investigated.

• A cross-sectional multicenter study including a total of 342 patients with psoriasis (mean age of the patients: 45.9 ± 14.2 years; average duration of psoriasis: 192 ± 134.7 months).

• Analysis revealed that adherence to systemic therapy was 57.6%.

• The injection-therapy group and the oral-therapy group did not differ with respect to adherence to the treatment.

• Inability to go to the hospital (19.2%), concern about the COVID-19 infection (16.3%), and discontinuation by the doctor (13.7%) were described as the most frequent reasons for non-adherence to treatment.

• In the present study, there appeared a negative effect of psoriasis severity and duration of medicine use on adherence to treatment.
