Özet

Introduction: Juvenile Systemic Lupus Erythematosus (jSLE) is a rare pediatric rheumatic disease marked by systemic inflammation that can cause organ damage. Compared to adults, it often follows a more severe course in children. Corticosteroids are widely used for their rapid antiinflammatory effects; however, their adverse events have made steroidsparing strategies increasingly important in disease management. Objectives: This study aimed to evaluate the impact of corticosteroid use on disease activity and damage index in patients diagnosed with jSLE. Methods: This was a multicenter, retrospective study including patients who were followed for at least 12 months due to jSLE. Lowdose corticosteroid therapy was defined as 0.01–0.03 mg/kg/day (maximum 7.5 mg/day) of prednisolone. The annual cumulative steroid dose (mg/day) was calculated by dividing the total amount of steroid received on treatment days by the product of 365.25 and the number of years. Data collected included SLE Disease Activity Index (SLEDAI) and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) at the initial and final visits, laboratory findings, and flare characteristics Results: A total of 138 patients from 11 centers were enrolled. Of these, 121 (87.7%) were female and 17 (12.3%) were male. The median age at diagnosis was 14 years (range: 2–16), and the median follow-up period was 36 months (range: 12–170). At diagnosis, 21 patients had organ damage, while 19 had organ damage at their last visit. Of the 10 patients who had damage at diagnosis, damage persisted in the final visit. Observed damage included cataracts (n=5, 3.6%), nephroticrange proteinuria (n=5, 3.6%), erosive arthritis (n=4, 2.9%), cognitive dysfunction (n=3, 2.3%), avascular necrosis (n=2, 1.4%), and one patient each (0.7%) with decreased GFR (<50%), retinal changes or optic atrophy, venous thrombosis, pancreatic insufficiency, stroke, transverse myelitis, end-stage renal disease, pulmonary hypertension, pleural fibrosis, reduced lung capacity, previous myocardial infarction, valvular involvement, muscle atrophy, vertebral height loss, and scarring alopecia. Although follow-up durations were similar between groups, patients with damage had higher SLEDAI scores at both initial and final visits and took longer to achieve low-dose steroid therapy. Additionally, the proportion of patients who achieved Lupus Low Disease Activity State (LLDAS) was significantly lower in the damage group (p=0.02). Conclusion: Organ damage in jSLE is associated with increased morbidity and mortality. Identifying and mitigating factors that contribute to long-term damage is essential. While glucocorticoids are effective and accessible agents for disease control, they should be used at the lowest effective dose and for the shortest duration possible to minimize adverse outcomes.
