Background: No currently approved treatment for pediatric plaque psoriasis selectively targets interleukin (IL)-23. In adults, guselkumab (a selective IL-23 inhibitor targeting the p19 subunit) demonstrated substantial efficacy with a favorable safety profile in treating moderate-to-severe plaque psoriasis.
Objective: PROTOSTAR (NCT03451851) evaluated the efficacy and safety of guselkumab in pediatric patients with moderate-to-severe plaque psoriasis.
Background: Suboptimal influenza and pneumococcal vaccination rates have been reported before the COVID-19 pandemics in certain populations at risk for severe infection. The aim of this longitudinal cohort study was to investigate changes in influenza and pneumococcal vaccination rates and patient perceptions in patients with psoriasis (PsO) before and during the pandemic.
Methods: Data on vaccination, patient and disease characteristics, comorbidity, and patient perceptions were collected with questionnaires before and during the pandemic approximately one year later.
