Increased risk of superficial fungal infections among psoriasis patients receiving systemic treatment: A nationwide retrospective population-based cohort study

Abstract Previous meta-analyses or large cohort studies of risk for onychomycosis or mucocutaneous candidiasis in psoriasis patients has been reported. We conducted the retrospective nationwide population-based cohort study to assess the incidence and risk of superficial fungal infections among patients with psoriasis receiving systemic treatment. Our study showed an increased risk of superficial fungal infection among patients with psoriasis receiving systemic treatment regardless of treatment type.
