In research published in Arthritis & Rheumatology, investigators developed and validated a tool called PRESTO that identifies patients with psoriasis who face an elevated risk for developing psoriatic arthritis and may therefore benefit from preventive therapies. The PRESTO calculator is available online.

The University of Toronto psoriasis cohort followed 635 patients with psoriasis, and 51 and 71 developed psoriatic arthritis during 1-year and 5-year follow-up periods, respectively. The risk of developing psoriatic arthritis within 1 year was higher in patients with younger age; male sex; family history of psoriasis; back stiffness; nail pitting (dents, ridges, and holes in the nails); joint stiffness; use of biologic medications; poor health; and pain severity. The risk of developing psoriatic arthritis within 5 years was higher in patients with morning stiffness, psoriatic nail lesion, psoriasis severity, fatigue, pain, and use of systemic non-biologic medication or phototherapy.

Taking these data into account, PRESTO uses a mathematical model to estimate a patient’s risk of developing psoriatic arthritis.

“The PRESTO tool could serve future efforts to reduce the progression from psoriasis to psoriatic arthritis. For example, PRESTO can be used to enrich prevention trials with at-risk populations. It can also identify patients with psoriasis who can benefit from early treatments, and it can serve as an educational tool for patients to increase awareness of psoriatic arthritis risk,” said corresponding author Lihi Eder, MD, PhD, of Women’s College Hospital and the University of Toronto, in Canada. “Ultimately, we hope that these efforts will improve the lives of people living with psoriatic disease.”

Brepocitinib Promising in Treatment of Psoriatic Arthritis

Brepocitinib is an oral drug that inhibits certain enzymes involved in inflammation (called tyrosine kinase 2 and Janus kinase 1) and is being tested for the treatment of several immunological diseases. A phase IIb randomised clinical trial published in Arthritis & Rheumatology recently generated promising efficacy and safety data for the use of brepocitinib in adults with moderately-to-severely active psoriatic arthritis.

Psoriatic arthritis is a type of arthritis that affects some people with psoriasis. It typically causes affected joints to become swollen, stiff and painful. Like psoriasis, psoriatic arthritis is a long-term condition that can get progressively worse.

Overall, 218 participants were randomised to receive either a low or high dose of brepocitinib or placebo for 1 year. After 16 weeks of treatment, 30 and 60mg daily doses of brepocitinib were superior to placebo at reducing signs and symptoms of psoriatic arthritis. Response rates were maintained or improved through week 52. Side effects were mostly mild or moderate.

“These data demonstrate striking efficacy and confirm the relevance of multiple signaling pathways dependent on the kinases targeted by brepocitinib in psoriatic arthritis,” said corresponding author Philip Mease, MD, of Swedish Medical Center/Providence St. Joseph Health and the University of Washington, in Seattle. “The safety is also reassuring for brepocitinib in this study.”
