a multi-center, randomized to compare the efficacy of ivig alone and ivig plus high-dose aspirin in kawasaki disease

Conditions: Kawasaki Disease

Summary: kawasaki disease (kd) is an acute febrile systemic vasculitis most commonly seen in children under the age of 5 years old. this trial has been designed as a multi-center, prospective, randomized controlled, evaluator-blinded trial with two parallel groups to determine whether ivig alone as the primary therapy in acute-stage kd is as effective as ivig combined with high-dose aspirin therapy. the primary endpoint is defined as cal formation at 6-8 weeks.

background: kawasaki disease (kd) is an acute febrile systemic vasculitis most commonly seen in children under the age of 5 years old. high-dose aspirin is often administered, but the duration of such treatment varies. many centers reduce the aspirin dose once the patient is afebrile, even before treating said patient with ivig. however, a randomized controlled trial regarding high-dose aspirin in the acute stage of kd has not previously been carried out. methods/design: this trial has been designed as a multi-center, prospective, randomized controlled, evaluator-blinded trial with two parallel groups to determine whether ivig alone as the primary therapy in acute-stage kd is as effective as ivig combined with high-dose aspirin therapy. the primary endpoint is defined as cal formation at 6-8 weeks. patients meeting the eligibility criteria are randomly assigned (1:1) to a test group (that receives only ivig) or a standard group (that receives ivig plus high-dose aspirin). this clinical trial is conducted at seven medical centers in taiwan. discussion: since high-dose aspirin has significant anti-inflammatory and anti-platelet functions, it does not appear to lower the frequency of disease outcomes. furthermore, it can decrease hemoglobin levels. therefore, the investigators have initiated this randomized controlled trial to determine whether high-dose aspirin is necessary in the acute stage of kd.

Eligibility criteria:
inclusion criteria: 1. male or female, under the age of 7 years old. 2. fulfilled the aha criteria for kd as explained below: 1. fever (more than 38.0℃ ear temperature) \> or = 5 days, as well as 4 of the 5 following symptoms 2. diffuse mucosal inflammation (strawberry tongue, dry and cracked lips) 3. bilateral non-purulent conjunctivitis 4. dysmorphous skin rashes 5. indurative edematous change over the hands and feet, or desquamation over the fingertips or toes 6. cervical lymphadenopathy (one or more nodule at least 1.5 cm in diameter) 3. an informed consent form (icf, appendix b) signed by the patient or a legal guardian. - exclusion criteria: 1. had symptoms that did not completely match the kd criteria. 2. had an acute fever for \ 10 days 3. ivig treatment at another hospital before being referred to the study center. 4. treatment with corticosteroids, other than the inhaled form, in the two weeks prior to joining the study; 5. the presence of a disease known to mimic kawasaki disease (such as adenovirus infection, toxic shock syndrome etc.). 6. previous kd diagnosis. 7. inability to take aspirin (such as history of hypersensitivity to aspirin, g6pd deficiency, recent herpes zoster infection or vaccination, etc.) 8. afebrile prior to enrollment 9. cal prior to enrollment 10. severe concomitant medical disorders (e.g., immunodeficiency, chromosomal anomalies, congenital heart diseases, metabolic diseases, nephritis, collagen diseases, etc.) 11. suspected to have an infectious disease, including sepsis, septic meningitis, peritonitis, bacterial pneumonia, varicella, and influenza 12. judged by the researcher to be unsuitable for this trial. -
