Experience in managing psoriasis patients receiving targeted therapy during the covid-19 pandemic

Abstract

Introduction. With the onset of the COVID-19 pandemic the dermatological manifestations of the infection are widely discussed along with the correct management tactics for patients with severe chronic dermatoses, primarily those on immunosuppressive therapy. Immunocompromised patients are overly vulnerable to infections, which is especially important in the context of the pandemic. The article provides up-to-date literature information regarding the general risks of infection in patients receiving systemic immunomodulatory agents for the treatment of psoriasis, as well as evidence based treatment recommendations, including the example of our own clinical experience of using targeted therapy during the COVID-19 pandemic. Purpose of the study. The aim of the study was to analyze the therapeutic efficacy and safety of the systemic immunomodulatory drugs therapy in the context of the global COVID-19 pandemic. Materials and methods. The study included 142 patients with psoriasis receiving GEBD and small molecules therapy at the Department of Anti-Cytokine Therapy and Efferent Methods of Treatment of MNPCDK DZM. All patients were examined to deter-mine their level of IgM and IgG antibodies to the SARS-CoV-2 virus strain in the blood serum. All patients continued to receive therapy according to their individual dosing regimen. The study was conducted at a time of high morbidity in the city of Moscow. Results. The overall morbidity among the studied patients was 13.4% of which the majority were patients with an asymptomatic course of the disease. It should be noted that there was a low incidence rate among patients receiving therapy with IL-17 inhibitors (secukinumab, netakimab). Conclusion. Our study confirms worldwide records that there is no evidence of an increased risk of COVID-19 among patients receiving targeted therapy for psoriasis. In our opinion, the discuntinuation of the current treatment can lead to unjustified risks, such as a relapse of psoriasis, including with severe manifestations and subsequent possible ineffectiveness when resuming therapy. Potentially, the termination of therapy that suppresses the production of proinflammatory cytokines will lead to an increase in the “cytokine storm” and a worsening of the course of viral infection when it occurs.
