Psoriatic Arthritis: Your Joints, Skin and Treatment History as Research Data

Every figure in this guide comes from a published source, linked where it appears and kept in CureCircle's evidence base with the source's own words. It is not medical advice. Read on 7 November 2026.

Psoriatic arthritis sits between two specialties: the skin and the joints. Many people see a dermatologist for years before joint pain is recognised as part of the same disease, and then work through a series of medicines, from anti-inflammatories to methotrexate to biologics, until one controls both. That journey, with the scans, scores and the person's own account of pain, fatigue and skin, is what research on psoriatic arthritis needs.

How many people live with it

A 2024 meta-analysis found that the worldwide prevalence of psoriatic arthritis was 112 per 100,000 adults. A pooled analysis of population studies found new cases at 83 per 100,000 person-years.

The records worth keeping

NICE's guidance on spondyloarthritis and on biologic treatment describes the tests and assessments that leave records:

• X-rays of hands and feet: NICE recommends plain film X-ray of symptomatic hands and feet when psoriatic arthritis is suspected.
• Ultrasound of the hands, feet and tendon attachments if a diagnosis cannot be made from the X-ray.
• A response score on biologics: treatment is continued only with an adequate response using the Psoriatic Arthritis Response Criteria (PsARC) at 12 weeks.

People with psoriasis are offered an annual check for psoriatic arthritis, so your psoriasis records belong in the story too. If you do not have your scan reports or letters, ask your rheumatology service for a copy.

What sharing it is worth

CureCircle values every contribution with a public benchmark built from what health data has sold for. A complete psoriatic arthritis story with the records the guidance lists comes to about $74 per licence on the benchmark today. Every line and its source is on the psoriatic arthritis page, and the psoriasis guide covers the skin side.

A licence is not a one-off sale: the same de-identified story can be licensed to several research teams, and you earn a share each time.

People with psoriatic arthritis are also paid for their time directly: a published listing offered $120 for a 60-minute phone interview.

How to share it

You start by writing what you live with in your own words; a few quick questions follow, then an AI interviewer asks about the details only you know, and you rate every treatment you tried. You can add scan reports, blood results and clinic letters as PDFs or photos, and the AI reads them into your own medical file. Before anything is shared, you read the de-identified summary and decide.
