Background There is under reporting of prevalence of Psoriatic Arthritis among patients with psoriasis in India. The data on prevalence of PsA among patients of the psoriasis varies from 6.25% to 48% in western countries. , A relatively low figures are reported from Asian countries.
Objectives To determine the reporting of psoriatic arthritis from dermatology point of view
Methods In this observational study, we identified subjects from hospital recordswho were diagnosed with psoriasisand psoriatic arthritis between 1/07/2010till 31/05/2014and 01/01/2015 till 31/12/2015 inDepartment Dermatologyin a tertiary care Hospital.Age-and sex-specific incidence rates were recorded.In order to sensitize dermatologists about the aspect of psoriatic Arthritis series of close group meetings between dermatologists and Rheumatologists were conducted in order to pick up Arthritis in patients of Psoriasis. Six months post educational intervention, observation of the hospital records regardingdiagnosis of psoriasis and psoriatic Arthritis were recorded.
Results A total of 16842 patients were reviewed during the pre-education intervention period between 01/07/2010 till 31/05/2014. Out of these 771 (4.57%) patients were recorded as psoriasis but none of the patients were recorded as psoriatic arthritis. The mean± SD age of patients with psoriasis was 43.34± 16.72 years, 50.1% were males.A total of 6012 patients were reviewed during the post- education intervention period between 01/01/2015 till 31/12/2015. Out of these 331 (4.92%) patients were recorded as psoriasis and 35 (0.58%) patients were recorded as both psoriasis and psoriatic arthritis. The psoriatic arthritis patients were referred to rheumatologists and all were found to have PsA according to classification of psoriatic arthritis (CASPAR) criteria.The prevalence rate of psoriasis and psoriatic arthritis with age ≤10 years, 11–25 years, 26–50 years, 51–70 years, and >70 years was found to be 2.06% and 0%, 9.98% and 0.01%,52.9% and 0.9%, 29.8% and 0.8% and 5.2% and 0.6% respectively. The highest prevalence rate of psoriasis and psoriatic arthritis both was between 26–50 years of age
Conclusions Psoriatic Arthritis is underreported from dermatology registries. Rheumatologist and dermatologist should share a platform regarding the concept of Psoriatic Arthritis in patients with psoriasis
