Nail Changes May Indi­cate Psoriatic Arthritis

Certain nail features can help doc­tors distinguish between psoriasis and psoriatic arthritis, and possibly lead to earlier or improved treatment for PsA, a new study suggests. In the analysis of 1,092 patients with either PsA or psoriasis only, researchers found that nail changes were more common among those with PsA than psoriasis only. Transverse (side-to-side) grooves, splinter hemorrhages (small broken blood vessels under the nails) and onycholysis (separation of the nail from the nail bed) were associated with arthritis. Transverse grooves were significantly associated with arthritis in the joint closest to the nail and enthesitis, inflammation where the tendons and ligaments insert into the bone.

Enthesitis and Dactylitis Associated With Greater Disease Burden

The presence of dactylitis – inflammation of the fingers and/or toes – and enthesitis – inflammation of the sites where the tendons or ligaments insert into the bone – can have important implications for people with PsA. A study of 1,567 PsA patients found that, overall, those with dactylitis or enthesitis had greater disease activity.

Additionally those with enthesitis had worse functional status, reported more pain and fatigue and were more likely to have work impairment. The study’s authors say their findings underscore the importance of identifying, assessing and managing enthesitis and dactylitis in people with PsA.
