Summary
This study suggests a link between psoriasis and alopecia areata. Nail pitting in alopecia areata patients may indicate underlying psoriasis.
Area of Science:
- Dermatology
- Clinical Research
Background:
- Psoriasis (Ps) and alopecia areata (Aa) are common dermatological conditions.
- The potential co-occurrence and relationship between Ps and Aa require further investigation.
Purpose of the Study:
- To investigate the association between psoriasis and alopecia areata.
- To explore if nail pitting in alopecia areata is a manifestation of psoriasis.
Main Methods:
- A retrospective analysis of 5,033 patients examined between 1968 and 1975.
- Diagnosis of psoriasis and alopecia areata based on clinical examination.
Main Results:
- 407 patients were diagnosed with psoriasis (Ps) and 23 with alopecia areata (Aa).
- Five of the 23 Aa patients also had Ps.
- One Aa patient with nail pitting, whose sibling had Ps, was noted.
Conclusions:
- Evidence suggests a potential association between psoriasis and alopecia areata.
- Nail pitting observed in alopecia areata cases might be an indicator of psoriasis.
