Can neutrophil-to-lymphocyte ratio predict cardiac involvement in kawasaki disease?

Introduction Kawasaki disease (KD) is an acute self-limited vasculitis, in which 1/3 of patients develop coronary artery lesions (CAL) if untreated. Although studies have explored potential biomarkers to predict patients with KD who are at risk of CAL, no useful single marker exists. The blood neutrophil to lymphocyte ratio (NLR) is identified as a potentially useful marker of clinical outcome in inflammatory diseases.
