Epidemiology of Diabetes Mellitus in Patients With Psoriatic Arthritis: Current Evidence.

What was studied

This review asked how common diabetes is in people with psoriatic arthritis. It searched databases up to February 2025. It included studies that only observed people. It analysed 293,582 patients with psoriatic arthritis. Patients were split into groups where treatment was shared and groups where it was not.

What they found

The abstract gives the overall share with diabetes for both groups. Rates differed by region. Where treatment was not shared, South America and Asia had higher rates. Europe and North America had lower rates. Where treatment was shared, South America was highest, then Asia. Age, type of diabetes, region and study design added to the gaps between studies. Small-study effects were seen in one subgroup. They were also seen in people on drugs plus biologics.

What it means for patients

The authors say diabetes rates link to the type of study and to region. They say the findings support routine screening for metabolic problems in psoriatic arthritis. They say studies that follow people over time are needed.

Why it is not certain yet

The studies differed a lot from each other. Small-study effects can skew results. These were observational studies, which show how common a problem is, not why. Rates were linked to region and study type, but the abstract does not show why.
