Summary
Psoriatic arthritis frequently affects nails, with 86.5% of patients showing onychopathy. Common nail changes include subungual hyperkeratosis in toenails and pitting in fingernails.
Area of Science:
- Rheumatology
- Dermatology
- Orthopedics
Background:
- Psoriatic arthritis (PsA) is a chronic inflammatory disease.
- Nail involvement, or onychopathy, is a common manifestation in PsA patients.
- Limited data exists on the prevalence and specific features of onychopathy in PsA.
Purpose of the Study:
- To investigate the rate of nail involvement (onychopathy) in patients with psoriatic arthropathy.
- To identify the typical clinical features of onychopathy in this patient cohort.
Main Methods:
- A study was conducted on 52 patients diagnosed with psoriatic arthropathy.
- Patients were examined for the presence and characteristics of nail changes.
- Data collection focused on identifying specific types of onychopathy in both fingernails and toenails.
Main Results:
- Nail abnormalities were observed in a high percentage of patients, specifically 86.5%.
- The most frequent toenail alteration identified was subungual hyperkeratosis.
- The most common fingernail change noted was pitting.
Conclusions:
- Onychopathy is highly prevalent in patients with psoriatic arthropathy.
- Specific nail changes like subungual hyperkeratosis and pitting are characteristic findings.
- These findings highlight the significant association between psoriatic arthritis and nail disease.
