Description
Güneş and co-authors compare nail changes across four inflammatory diseases in this 2026 prospective study. Psoriasis and its joint form are famous for nail damage. Rheumatoid arthritis and ankylosing spondylitis also inflame the body. Their nail signs, though, were little charted. The team examined 100 patients, 25 per disease, checking 1,000 fingernails by eye and 200 under a magnifier in a technique called onychoscopy.
Patterns differed clearly by disease: pitting and nail lifting dominated in psoriasis and psoriatic arthritis, white nails in ankylosing spondylitis, and rough vertical ridging in rheumatoid arthritis. Under magnification, clustered tiny blood vessels were typical of the psoriasis groups, while parallel vessel patterns marked rheumatoid arthritis. Some vessel signs tracked with inflammation markers in the blood, suggesting nail inspection could offer quick clues when separating these conditions.
