Summary

Kawasaki disease (KD) is an acute self-limited vasculitis of infancy and early childhood. Most patients recover without sequelae although the inflammatory process causes permanent damage to the coronary arteries in 20-25% of untreated children. An infectious aetiology is suspected, but the causative agent has not been identified. The investigators aim to identify the genes underlying both susceptibility to Kawasaki disease, and the development of coronary artery aneurysms.

Detailed description

The problem to be addressed; Kawasaki disease is now the most common cause of acquired heart disease in children in Japan and North America. Kawasaki disease arises when genetically predisposed children encounter an as yet unidentified infectious agent which may cause only mild illness or no illness at all in children without the genetic predisposition. Other children may suffer permanent damage to the coronary arteries. Identification of the genes involved will help to improve understanding of the disease, and the development of better treatments. Objective The investigators aim to identify the genes underlying both susceptibility to Kawasaki disease, and the development of coronary artery aneurysms. Design The study will recruit nuclear families (affected child and their biological parents) through participating NHS hospitals or through the records of the UK Kawasaki Support Group. Study size 400 affected children and both biological parents (i.e. 1200 participants) Procedures Informed consent using age appropriate patient/parent/guardian information sheets will be taken from parents (or from children aged 16 and over), assent will be taken from the child under the age of 16 (if appropriate). Children recruited during the acute illness; routine clinical and laboratory data and research samples (blood, urine, throat swab). Children recruited retrospectively; study questionnaire (completed by parents), saliva samples.Saliva samples from parents
