- Brief summaryBackground of the study:
Kawasaki disease is an acute systemic vasculitis in childhood, in which coronary artery aneurysms can develop as a complication. Kawasaki disease is the leading cause of acquired heart disease in childhood. Standard treatment consists of a single infusion of high dose intravenous immunoglobulin (IVIG) and acetylsalicylic acid (aspirin). Coronary artery aneurysms develop in 15-25% of untreated children. Treatment with IVIG has reduced this risk to less than 10%. The majority of patients recover quickly after the start of the IVIG treatment, but approximately 15-20% of children do not respond to this standard treatment. Children who are unresponsive to IVIG have an increased risk of developing aneurysms. Although Kawasaki disease was first described in 1967, the cause of the disease is still unknown. Since no causative pathogen(s) have been found, it is not clear which children are susceptible to Kawasaki disease. There is no test to diagnose Kawasaki disease. Difference in incidences observed between different ethnic populations and the results of twin studies, make it likely that the genetic predisposition of the child also plays a role. Questions about the future of these patients are also important. Are only children with coronary aneurysms at increased risk of cardiovascular diseases in later life, or are unaffected children also at risk due to the prior vasculitis? Previous studies are limited and often inconclusive.

Objective of the study:
The objective is to gain more insight in: 1. Possible causative agents of Kawasaki disease. At the moment no single causative agent has been identified despite the strong suspicion of an infectious etiology of the disease. 2. Genetic factors related to susceptibility and disease course of Kawasaki disease. 3. Influence of this pediatric vasculitis on long term cardiovascular outcome measures.

Study design:
Prospective, cross-sectional and (partly) longitudinal study

Study population:
All patients diagnosed with "Kawasaki disease" (according to the diagnostic criteria) in the participating centers will be asked to participate in the study.

Primary study parameters/outcome of the study:
1. Causative agents: one or more viruses / bacteria involved in triggering Kawasaki disease
2. Genetics: genetic variation in the human genome (e.g. single nucleotide polymorphisms [SNPs] in the IgG receptors (i.e. Fc-gamma receptors) is associated with disease susceptibility, course of the disease (coronary artery aneurysms), and the clinical reaction to standard treatment with IVIG
3. Long-term effects: assessment of a cardiovascular risk profile

Secundary study parameters/outcome of the study (if applicable):
- Nature and extent of the burden and risks associated with participation, benefit and group relatedness (if applicable): Additional blood and body fluids for microbial tests (microbiome analysis; DNA analysis). Another disadvantage of study participation is the traveling time for the families to visit our multidisciplinary outpatient care unit at the AMC (instead of the nearby hospital of admission) at 6-12 months after the acute onset of disease. During this standard visit the extra blood withdrawal for our study will be combined with the standard blood tests. During the ultrasound examination of the neck vessels, the patient must lie as still as possible, which can be difficult for a young child. The ultrasound examination will not exceed 20 minutes, is painless and has no known side- or after-effects.
