Evaluation of Demographic, Clinical and Laboratory Features of Patients with Systemic Lupus Erythematosus in Kermanshah

Background: Systemic lupus erythematosus (SLE) is a worldwide autoimmune disease. The disease has different etiologies, clinical and laboratory symptoms between different geographical and racial groups, and sufficient knowledge of the type of symptoms in each region can play a proper role in diagnosis and treatment. Objectives: This study was performed to evaluate demographic, clinical and laboratory features of patients with systemic lupus erythematosus in Kermanshah. Methods: This study is descriptive, analytical and cross-sectional. The files of 150 patients with lupus during 2016 - 2018 in Imam Reza hospital in Kermanshah were reviewed. Results: Data analysis showed that patients at the time of referral were with musculoskeletal symptoms 37.3% (56 individuals), cutaneous-mucosal 32% (48 individuals), constitutional 51.3% (77 individuals), renal 62% (93 individuals), cardiac 6.7% (10 individuals), neurological manifestations 17.3% (26 individuals), pulmonary involvement 37.3% (56 individuals), and Hematological 71.3% (107 individuals). The anti-nuclear antibody (ANA) in 60% (90 individuals), anti-double strand DNA Antibody (anti-ds DNA) in 35.4% (53 individuals), C-Reactive Protein (CRP) in 44.6% (67 individuals), lower level of normal C3 and C4 in 33.3% (50 individuals) and 11.3% (17 individuals), respectively, lupus anticoagulant in 13.3% (20 individuals), antibody citrullinated peptide anti-cyclic (anti-CCP) in 14.9% (22 individuals), anticardiolipin IgM and IgG, in 6% (9 individuals) and 9.3% (14 individuals) of patients respectively were observed. Also, anemia was observed in 34% (51 individuals), leukopenia in 22% (33 individuals), and thrombocytopenia in 30.7% (46 individuals). Abnormal ESR (erythrocyte sedimentation rate) was seen in 59.3% (89 individuals) of patients. Leukopenia in men and positive CRP in women were more common (P = 0.014, P = 0.004). Conclusions: Despite the diverse clinical and laboratory manifestations of SLE in different racial and geographical groups, paying attention to these differences in each region can effectively diagnose the disease. As in this study, hematological manifestations had a higher percentage in the population of lupus patients in Kermanshah.
