Key clinical point: Tildrakizumab was able to reduce the occurrence of psoriatic arthritis (PsA) in patients with psoriasis by improving nailfold bleeding (NFB) and capillary enlargement, which are well-known risk factors for the development of PsA.
Major finding: NFB (hazard ratio [HR] 2.92; P = .003) and capillary enlargement (HR 4.61; P < .0001) were recognized as risk factors for PsA development; however, both conditions improved significantly after 1 month of tildrakizumab initiation, with the improvements being sustained up to 13 months (all P < .01). Therefore, tildrakizumab treatment significantly reduced the risk for PsA (HR 0.06; P = .007) in patients with psoriasis.
Study details: Findings are from a prospective cohort study which included 246 patients with psoriasis vulgaris having no prior exposure to systemic treatments and topical treatments for distal interphalangeal joints and nails who received either tildrakizumab (n = 20) or topical agents (n = 226).
