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.
