RESUMO
OBJECTIVE: To evaluate practice variation in pharmacologic management in the International Kawasaki Disease Registry (IKDR). STUDY DESIGN: Practice variation in intravenous immunoglobulin (IVIG) therapy, anti-inflammatory agents, statins, beta-blockers, antiplatelet therapy, and anticoagulation was described. RESULTS: We included 1627 patients from 30 IKDR centers with maximum coronary artery aneurysm (CAA) z scores 2.5-4.99 in 848, 5.0-9.99 in 349, and ≥10.0 (large/giant) in 430 patients. All centers reported IVIG and acetylsalicylic acid (ASA) as primary therapy and use of additional IVIG or steroids as needed. In 23 out of 30 centers, (77%) infliximab was also used; 11 of these 23 centers reported using it in <10% of their patients, and 3 centers used it in >20% of patients. Nonsteroidal anti-inflammatory agents were used in >10% of patients in only nine centers. Beta-blocker (8.8%, all patients) and abciximab (3.6%, all patients) were mainly prescribed in patients with large/giant CAAs. Statins (2.7%, all patients) were mostly used in one center and only in patients with large/giant CAAs. ASA was the primary antiplatelet modality for 99% of patients, used in all centers. Clopidogrel (18%, all patients) was used in 24 centers, 11 of which used it in >50% of their patients with large/giant CAAs. CONCLUSIONS: In the IKDR, IVIG and ASA therapy as primary therapy is universal with common use of a second dose of IVIG for persistent fever. There is practice variation among centers for adjunctive therapies and anticoagulation strategies, likely reflecting ongoing knowledge gaps. Randomized controlled trials nested in a high-quality collaborative registry may be an efficient strategy to reduce practice variation.

OBJECTIVE: To describe the similarities and differences in the evaluation and treatment of multisystem inflammatory syndrome in children (MIS-C) at hospitals in the US. STUDY DESIGN: We conducted a cross-sectional survey from June 16 to July 16, 2020, of US children's hospitals regarding protocols for management of patients with MIS-C. Elements included characteristics of the hospital, clinical definition of MIS-C, evaluation, treatment, and follow-up. We summarized key findings and compared results from centers in which >5 patients had been treated vs those in which ≤5 patients had been treated. RESULTS: In all, 40 centers of varying size and experience with MIS-C participated in this protocol survey. Overall, 21 of 40 centers required only 1 day of fever for MIS-C to be considered. In the evaluation of patients, there was often a tiered approach. Intravenous immunoglobulin was the most widely recommended medication to treat MIS-C (98% of centers). Corticosteroids were listed in 93% of protocols primarily for moderate or severe cases. Aspirin was commonly recommended for mild cases, whereas heparin or low molecular weight heparin were to be used primarily in severe cases. In severe cases, anakinra and vasopressors frequently were recommended; 39 of 40 centers recommended follow-up with cardiology. There were similar findings between centers in which >5 patients vs ≤5 patients had been managed. Supplemental materials containing hospital protocols are provided. CONCLUSIONS: There are many similarities yet key differences between hospital protocols for MIS-C. These findings can help healthcare providers learn from others regarding options for managing MIS-C.

OBJECTIVE: To determine the safety and pharmacokinetics of etanercept (Amgen, Thousand Oaks, California) a tumor necrosis factor-α receptor blocker, in children with acute Kawasaki disease (KD). Standard therapy of acute KD includes intravenous immunoglobulin (IVIG) and high-dose aspirin, but a substantial number of patients are refractory and require additional treatment. Tumor necrosis factor-α levels are elevated in children with KD, suggesting a role for etanercept in treatment. STUDY DESIGN: We performed a prospective open-label trial of etanercept in patients with KD (age range, 6 months-5 years; n = 17) meeting clinical criteria and with fever ≤ 10 days. All received IVIG and high-dose aspirin. They received etanercept immediately after IVIG infusion and then weekly two times. For the initial safety evaluation, the first 5 patients received 0.4 mg/kg/dose. Subsequent subjects received 0.8 mg/kg/dose. RESULTS: Fifteen patients completed the study. The pharmacokinetics were similar to that in older children in published series. No serious adverse events related to etanercept occurred. No patient demonstrated prolonged or recrudescent fever requiring re-treatment with IVIG. No patient showed an increase in coronary artery diameter or new coronary artery dilation/cardiac dysfunction. CONCLUSION: Etanercept appears to be safe and well tolerated in children with KD. The data support performance of a placebo-controlled trial.
