Evaluation of joint involvement in patients of psoriasis: an observational study
Abstract
Background Psoriasis is a common, genetically-determined inflammatory disease characterized by well-demarcated, erythematous scaly papules and plaques. Usually 20-30% of patients with psoriasis develop seronegative, peripheral and/or spinal arthropathies. Various patterns of arthritis have been reported in patients of psoriasis in different studies from different parts of world.Objective We carried out this clinical survey to find out different patterns of joint involvement in patients of psoriasis in this part of the world.Patients and methods All psoriatic patients of either sex and any age were enrolled from the inpatient and outpatient Dermatology departments of Allama Iqbal Medical College/Jinnah Hospital, Lahore from 1st April to 30th November 2006. They were thoroughly examined, investigated and recorded on the predesigned pro forma.Results Of 104 patients enrolled, 37 showed joint involvement and all were rheumatoid factor-negative. Symmetrical rheumatoid-like seronegative polyarthritis was the commonest pattern noted (43%) while cervical, temporomandibular and sternomanubrial joints involvement was not seen.Conclusion All forms of psoriatic arthropathy as mentioned by Moll and Wright were found in the present study, symmetrical rheumatoid-like seronegative polyarthritis being the most common.References
