Background:

Psoriatic arthritis is a chronic systemic inflammatory condition characterized by arthritis associated with psoriasis of the skin and nails with negative rheumatoid factor and absence of rheumatoid nodules. Early diagnosis will help prevent unhelpful examinations and therapies and help in treating the patient in early stages of the disease.

Objective:

The objective was to compare the PASE(Psoriatic Arthritis Screening and Evaluation score) with the PASI (Psoriatic area severity index) score, NAPSI (Nail psoriasis severity index) score, duration of disease and treatment.

Materials and methods:

111 patients coming to Dermatology OPD and clinically diagnosed as psoriasis were taken for the study after taking a written informed consent. PASE score was compared with the other scores (PASI, NAPSI) as well as the clinical examination findings of the patient as well as the treatment medication and duration.

Results:

There was significant co–relation between the PASE score and the duration of disease and treatment. There was no significant co–relation between the PASE score with the PASI and NAPSI score.

Conclusion:

There is a significant increase in the incidence and severity of psoriatic arthritis with the duration of disease. They is no co–relation with the severity of skin or nail lesions in psoriasis and the severity of arthritis.
