IL-17 inhibitors carried up to nearly five times the candidiasis risk of other psoriasis systemics
BADBIR's 118,000 person-years clarify infection risk by class; experts put oral JAK inhibitors first for severe alopecia areata; an IL-36 receptor antibody cleared pustules in a week in a small GPP trial; and a gene-expression score is pitched at adjuvant radiotherapy in high-risk cSCC.
The edition in brief
In the British Association of Dermatologists biologics register, 18,635 adults with psoriasis contributed 118,018 person-years on systemic treatment. Tuberculosis (0.19 per 1000 person-years) and meningitis (0.25) were rare and mostly followed TNF-α inhibitors, especially adalimumab. IL-17 inhibitors were the only class with raised candidiasis risk, with incidence rate ratios from 2.67 versus apremilast to 4.65 versus ustekinumab; individual IL-17 agents did not differ. A three-round Delphi of 31 US experts placed oral JAK inhibitors as primary long-term therapy for severe alopecia areata in adults, with dupilumab as an alternative in comorbid atopy and minoxidil, corticosteroids and topical agents as supplements. In a phase 2 trial in China, a single intravenous dose of recibokibart, an IL-36 receptor antibody, achieved near-clear pustulation at day 8 in 86.4% of 22 patients with a generalised pustular psoriasis flare versus 9.1% of 11 on placebo. A retrospective validation of an integrated 40-gene expression profile in 572 high-risk cutaneous squamous cell carcinomas reported over 95% negative predictive value for its lowest class and identified 12.9% as highest risk, with an apparent benefit from adjuvant radiotherapy.
Experts put oral JAK inhibitors first for severe alopecia areata
For adults with severe alopecia areata, treat an oral JAK inhibitor as long-term first-line therapy, with dupilumab as an option when atopy coexists.
A single IL-36 receptor antibody dose cleared GPP pustules within a week
Recibokibart is promising for GPP flares but remains investigational; manage flares now with established therapy and early specialist referral.
A 40-gene profile claims to pick out high-risk cSCC for adjuvant radiotherapy
Do not base adjuvant radiotherapy decisions on a gene expression profile yet; keep using clinicopathological staging and MDT review.
Ask about thrush before choosing an IL-17 inhibitor
Take a candidiasis history before prescribing an IL-17 inhibitor, and prefer an IL-23 inhibitor in those with recurrent thrush.
Match the psoriasis biologic to infection history: TB with TNF inhibitors, candida with IL-17
Choose the psoriasis biologic class with infection history in mind — avoid TNF inhibitors when TB risk is high and IL-17 inhibitors when candidiasis recurs.
