CRP and Hypoalbuminemia: A review of published cases demonstrates a consistent association between KDSS and more severe systemic inflammation, IVIG resistance, and frequent cardiac involvement.[16,17] Taddio et al found KDSS patients had significantly higher CRP, lower hemoglobin, and hypoalbuminemia compared to typical KD cases, with 60% of KDSS patients showing IVIG resistance.[16] Similarly, in our case, initial administration of IVIG failed to induce clinical improvement, indicating IVIG resistance; the patient subsequently responded well to adjunctive corticosteroid therapy and comprehensive supportive care.
