ObjectivesThis study was conducted to analyze clinical characteristics, laboratory data, disease activity, and outcome of juvenile systemic lupus erythematosus (jSLE) patients from southern Turkey.MethodsFifty-three patients with jSLE diagnosed according to the revised American College of Rheumatology 1997 criteria between January 2005 and June 2018 were included in the present study.ResultsThe median age at the diagnosis was 12.8 (range, 5.1-17.7) years. The female to male ratio was 9.6:1. The most prevalent clinical features were mucocutaneous involvement (96.2%) and constitutional manifestations (94.3%). Renal manifestations, hematological manifestations, and neuropsychiatric involvement were detected in 40 (75%), in 38 (71.7%), and in 13 (24.5%) patients, respectively. Renal biopsy was performed to 49 patients (92.5%). Class IV lupus nephritis (LN) (34%) and class II LN (20.4%) were the most common findings. Mycophenolate mofetil, cyclophosphamide with corticosteroid were the main treatment options. Eighteen patients received rituximab and one tocilizumab. The mean SLE Disease Activity Index (SLEDAI) score at the time of diagnosis was 22.478.8 (range=3-49), and 1.34 +/- 1.85 (range=0-7) at last visit. Twenty-one patients (39.6%) had damage in agreement with Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (PedSDI; mean=0.60 +/- 0.94; range=0-5) criteria. Growth failure was the most prevalent cause of damage (n=13, 26%). One patient deceased due to severe pulmonary hemorrhage and multiple cerebral thromboses.Conclusion p id=Par4 jSLE patients in this cohort have severe disease in view of the higher frequency of renal and neurologic involvement. Nevertheless, multicenter studies are needed to make a conclusion for all Turkish children with jSLE.
