N2 - BACKGROUND: mRNA-based COVID-19 vaccines have short and long-term efficacy in healthy individuals, but their efficacy in patients with psoriasis receiving immunomodulatory therapy is less studied.OBJECTIVE: To investigate long-term immunity after COVID-19 vaccination in patients with psoriasis receiving immunomodulatory therapy.METHODS: A prospective cohort study including patients (n = 123) with psoriasis receiving methotrexate (MTX) or biologics and controls (n = 226). Only mRNA-based COVID-19 vaccines administered with standard intervals between doses were investigated. Markers of immunity included SARS-CoV-2 spike-glycoprotein specific IgG and IgA, neutralizing capacity, and interferon-gamma release from T-cells stimulated with peptides of the SARS-CoV-2 spike-glycoprotein.RESULTS: The proportion of IgG responders was lower 6 months after vaccination in patients receiving anti-TNF compared to controls. Anti-TNF treatment was associated with lower IgG levels (β=-0.82, 95% CI -1.38 to -0.25: P = 0.001). The median neutralizing index was lower in the anti-TNF group, 50% inhibition (IQR 37-89) compared to controls, 98% inhibition (IQR 96-99), P < 0.001. Cellular responses were numerically lowest in anti-TNF group.CONCLUSIONS: Treatment with anti-TNF has an impact on the immunity elicited by mRNA-based COVID-19 vaccination in patients with psoriasis, resulting in a faster waning of humoral and cellular markers of immunity, however, the clinical implications are unknown.
