Psoriatic arthritis and nail changes: exploring the relationship

Area of Science:

• Rheumatology
• Dermatology
• Clinical Research

Background:

• Psoriatic arthritis (PsA) presents with diverse articular and extra-articular symptoms.
• The link between PsA and skin conditions is well-documented.
• The association between PsA and psoriatic nail changes is less understood.

Purpose of the Study:

• To review the existing literature on the relationship between psoriatic arthritis and nail changes.
• To synthesize findings on the prevalence and types of nail involvement in PsA patients.

Main Methods:

• A comprehensive literature search was conducted using PubMed, MEDLINE, and EMBASE.
• The review encompassed studies published from 1964 to 2012.
• Twenty-one articles were included in the final analysis.

Main Results:

• Nail changes were present in an average of 66% (SD 17.7) of patients with PsA.
• The specific types of nail changes and their correlations varied significantly across the reviewed studies.
• A high degree of variability was observed in the reported data.

Conclusions:

• The literature on nail changes in PsA shows considerable heterogeneity in findings.
• Further large-scale studies are recommended to better understand nail involvement in PsA.
• Standardized methodologies are needed for future research on psoriatic nail disease.
