Prevalence and Early Markers of Atherosclerosis in Adults With a History of Kawasaki Disease (Kawasaki)
Kawasaki disease (KD) is an acute systemic vasculitic syndrome with coronary tropism.
It has been reported worldwide, but it is ten times more common in Asian population. The annual incidence in children under 5 years in Europe is estimated at 8 to 100000. It is the second vasculitis of the child by its frequency after rheumatoid purpura. It occurs in 80% of cases between 1 and 5 years, with a maximal incidence around the age of 12 months.
It may results in acquired heart disease in children in developed countries, and may be the cause of premature coronary artery disease in adulthood.
A polymorphism was recently associated with the occurrence of disease in a Japanese and U.S population. (C allele of SNP itpkc_3, with a risk multiplied by 2). However, data are conflicting on this issue and the prevalence of this allel is unknown in North America and Europe populations.
The clinical picture of KD associate a persistent fever and an antipyretics resistance with mucocutaneous signs and bulky cervical lymphadenopathy usually unilateral. Diagnosis is confirmed by the presence of five clinical signs (major criteria). The presence of inconsistent coronary lesions in cardiac ultrasound can confirm the diagnosis.
KD can resolve spontaneously with no treatment. The severity of the disease is primarily related to complications of coronary aneurysms in acute or chronic stages.
Several arguments support the fact that adult patients have diffuse vascular lesions different from aneurysmal lesions initially described in childhood.
Despite abundance of publications on KD, there is no prospective or retrospective study which explored anomalies resulting from KD in adult subjects.
Therefore, this project will describe the patient's vascular evolution, the prevalence of atherosclerotic lesions and to determine the biological and functional abnormalities, markers of accelerated atherosclerosis.
Hypothesis : A history of Kawasaki disease represents a cardiovascular risk factor in adulthood.
The main objective is to evaluate the prevalence of atherosclerotic lesions, their extent and their severity in adults with a history of KD in childhood compared to a control population.
