MEASUREMENT OF VITAMIN (D) AND ITS RELATION TO PSORIATIC ARTHRITIS PATIANTS.

Aim of the work:The aim of this study is to determine the prevalence of vitamin D deficiency/insufficiency in psoriatic arthritispatients. Methodology:This study was carried out on thirty psoriatic arthritispatients(21female,9male) ,Serum vitamin D by ELISA and Plain x-ray on both hands ,lumbosacral spine and sacroiliac joints. Results:In thirty psoaritic arthritis patients, we found 18 patients (60%) have deficiency in vitamin D level, 6 patients (20%) have insufficiency in vitamin D level and 6 patients (20%) have normal vitamin D level. 10% of selected patients have pitting of nails , 6.7% have oncholysis and 3.3% have Hyperkeratosis,20 of patients (66.7%) have elevated ESR (>20 mm/h),18Patients (60.0%) were CRP negative.26.7% of selected patients have hyperuricemia(>6mg/dl in male 5.5 mg/dl in female). In X-Ray hand, we found 40% of selected patients have joint space narrowing, 30% have sclerosis , 23.3% erosion and 13.3% of our patients have periostitis.In X-Ray sacroiliac joint, we found 23.3%of patients have blurring of sacroiliac joint, 16.7% of patients have Pseudowidnening, 13.3%of patients with sclorsis of S.I joint and 10% of patients have Ankylosisof joint .40% of selected patients have syndesmophytesin In X-Ray lumbosacral spine . Conclusion:Vitamin D deficiency/insufficiency is common among psoriatic arthritispatients and no association established between diseases activities and vitamin D level.
