The two regimens of dalteparin combination therapy. *Aspirin (ASA) was decreased to 5 mg/kg/day if the patient was afebrile, clinically improving, and/or showed a CRP < 1.0 mg/dL. **Aspirin withdrawn after 1 month of illness unless there were cardiac sequelae. Dalteparin was administered until the patient was afebrile, clinically improving, and/or showed a CRP < 1.0 mg/dL. ***IVIG started on day 4 or 5 of illness (the first illness day was defined as the day of onset of fever >38°C).
