Official title
Clinical Study of Atorvastatin in the Treatment of Acute Kawasaki Disease Complicated With Coronary Artery Abnormalities in Children
Overview
The goal of this observational study is to learn about the safety and effects of atorvastatin in treatment of Chinese Kawasaki disease (KD) children complicated with coronary artery abnormalities (CAA) in acute phase. The main questions it aims to answer are: Is atorvastatin safe in Chinese children of acute KD? Does atorvastatin contribute to control the acute inflammation in KD and improve the CAA?
Detailed description
Kawasaki disease (KD) is acute self-limited vasculitis and occurs almost exclusively in childhood. It predominantly affects medium-sized arteries, most commonly coronary arteries. Although the use of intravenous immunoglobulin (IVIG) has obviously decreased the incidence of coronary arteries abnormalities (CAA), still a part of KD children occurs CAA, even medium, large or giant CA aneurysms. Coronary aneurysms can develop thrombus and arterial stenosis, which may cause severe cardiac events. Now KD has been the main cause of acquired heart disease in children in most areas of China mainland.
Studies have found that during the acute phase of KD, necrotizing arteritis occurs in coronary arteries. Oxidative stress, immune activation, and cellular infiltration of the vessel wall associated with secretion of proinflammatory cytokines, elastases, and matrix metalloproteinases (MMPs) are related to formation of coronary aneurysms. In addition, long-term KD vasculopathy appears ongoing vascular chronic inflammation and oxidative stress. Endothelial dysfunction, increased stiffness, and intima-media thickening have been noted in affected coronary arteries.
Statins, a hydroxymethylglutaryl coenzyme-A reductase inhibitors, has been widely used in adults for years not only for its reducing plasma cholesterol but also for its beneficial pleiotropic effects, including inflammation modulation, oxidative stress, endothelial function and angiogenesis, antithrombotic and antiplatelet effects. In recent years, statins have been considered to be used in KD children with coronary aneurysms. Several studies have shown reductions in high-sensitivity CRP, improved endothelial function and safety in such KD children treated with statins. The 2017 American Heart Association (AHA) scientific statement on KD has suggested that empirical treatment with low-dose statin may be considered for KD patients with past or current aneurysms, regardless of age or sex. The investigators have also conducted a follow-up study of atorvastatin used in long-term treatment of KD children with severe CAA. The results showed that long-term atorvastatin treatment was safe in Chinese KD children with CAA, but its dose was significantly lower than those been reported by previous studies abroad.
Based on the effects of statins on inhibition of MMP secretion and myofibroblast transformation which may anticipate the formation of CAA in acute KD, statins have been tried to be used in acute KD children with CAA. However, the relevant clinical data is very rare.Is atorvastatin safe in Chinese children of acute KD? Can atorvastatin actually contribute to control the acute inflammation of KD and improve CAA? The goal of this study is to learn about the safety and effects of atorvastatin in treatment of Chinese KD children complicated with CAA in acute phase.
Interventions
- Drug atorvastatin of dose level 1
The study is to be designed as dose-escalation protocol and enroll a minimum of 3 subjects per dose level (level 1, 0.15 mg/kg/day; level 2, 0.25 mg/kg/day; level 3, 0.4 mg/kg/day). Participants will take atorvastatin for 6 weeks. The dose-limiting toxicities (DLTs) are used to determine the maximum tolerated dose (MTD). - Drug atorvastatin of dose level 2
The study is to be designed as dose-escalation protocol and enroll a minimum of 3 subjects per dose level (level 1, 0.15 mg/kg/day; level 2, 0.25 mg/kg/day; level 3, 0.4 mg/kg/day). Participants will take atorvastatin for 6 weeks. The dose-limiting toxicities (DLTs) are used to determine the maximum tolerated dose (MTD). - Drug atorvastatin of dose level 3
The study is to be designed as dose-escalation protocol and enroll a minimum of 3 subjects per dose level (level 1, 0.15 mg/kg/day; level 2, 0.25 mg/kg/day; level 3, 0.4 mg/kg/day). Participants will take atorvastatin for 6 weeks. The dose-limiting toxicities (DLTs) are used to determine the maximum tolerated dose (MTD).
