With Psoriatic Arthritis, Bone Damage Increases With Age

The number of bone changes caused by psoriatic arthritis (PsA) goes up with age, according to researchers the University of Erlangen-Nuremberg in Germany.

The researchers found that bone erosions detected via imaging of the dominant hand increased from an average of 1.05 in people 20 to 40 to 2.0 at age 60, and the number of bone spurs went up from 7.5 in those 20 to 40 to 11.96 at age 60.

Previous research has suggested that psoriasis also has an underlying effect on bone. To learn more about these effects, the German researchers compared imaging results from 101 people with psoriatic arthritis (average age 50) — 55 of whom had psoriasis but no musculoskeletal symptoms and 47 healthy controls.

The researchers detected substantially more erosions and bone spurs in study participants whose psoriasis had begun at least 20 years earlier compared to those whose psoriasis skin involvement was less than 10 years in duration.
