The utility of interleukin-23 intraclass switching in the treatment of plaque psoriasis: a retrospective review of 43 cases.

Interleukin (IL)-23 inhibitors are a class of injectable biologics, which include risankizumab, tildrakizumab and guselkumab, used for the treatment of moderate-to-severe psoriasis. This retrospective review sought to determine the value of IL-23 inhibitor intraclass switching among patients with psoriasis after they experienced loss of efficacy to any IL-23 inhibitor. We conducted a retrospective chart review, including 43 patients who underwent any of 6 potential iterations of IL-23 intraclass switching between November 2017 and November 2023.

Low rates of vaccination among atopic dermatitis, alopecia areata, psoriasis, and psoriatic arthritis patients on biologics.

Biologics and Janus kinase (JAK) inhibitors are immunomodulating and immunosuppressing medications utilized to treat atopic dermatitis (AD), psoriasis (PSO), psoriatic arthritis (PsA), and alopecia areata (AA). Special recommendations must be considered when prescribing vaccinations in this population, as the pneumococcal and herpes zoster vaccine are recommended to patients ≥ 19-years-old (rather than ≥ 65-years-old and ≥ 50-years-old as in the general population, respectively), along with a yearly influenza and up to date COVID-19 vaccination. Additionally, TNF-α and JAK-inhibitors may increase the risk of latent Hepatitis B virus (HBV) reactivation among high-risk patients.
