Association of Inflammatory Biomarkers and Ferritin With Severity of Pediatric Systemic Lupus Erythematosus Patients

The goal of this observational study is to learn about the association of inflammatory biomarkers (SII, NLR, and PLR) and ferritin with disease severity in pediatric systemic lupus erythematosus (pSLE) patients. The main question it aims to answer is: Are higher levels of SII, NLR, PLR, and ferritin associated with greater disease severity (mild, moderate, severe based on SLEDAI-2K score) in pediatric SLE patients? Participants diagnosed with pediatric SLE will undergo routine blood tests to measure complete blood counts (NLR, PLR, SII) and serum ferritin, and their disease severity will be assessed using the SLEDAI-2K scoring system
