Kawasaki disease: current aspects on aetiopathogenesis and therapeutic management.
ABSTRACT Kawasaki disease (KD) is a vasculitis that affects mainly children of 6 months to 4 years old. It is important to be early recognised so as to limit the inflammatory cascade that may lead to aneurysmatic dilatations of coronary arteries. The causative agent of KD has not been still indentified and the aetiopathogenetic theories are based on epidemiologic, laboratory and histological data. The management of the disease is divided according to the clinical stage and patients' follow up should be continued for years after the disease onset. The exact period is determined by the risk level of the KD.

ABSTRACT: Kawasaki disease is an acute systemic vasculitis of unknown etiology. Diagnosis is based on clinical criteria that include fever, exanthema, conjunctivitis, changes in the extremities, erythema of oral mucosa and lips and cervical lymphadenopathy. However, these criteria have low sensitivity and specificity and therefore, other clinical and laboratory features may be helpful in establishing the diagnosis, especially for cases of atypical or incomplete Kawasaki disease. Prognosis depends on the extent of cardiac involvement; coronary aneurysms develop in 20–25% of untreated patients and these may lead to myocardial infarction and sudden death. Treatment with high-dose intravenous immunoglobulin is effective in reducing the risk of coronary aneurysms in most cases and is the treatment of choice for initial Kawasaki disease.Journal of Autoimmunity 01/2014; · 8.15 Impact Factor

ABSTRACT: Kawasaki disease (KD) is an acute, multisystemic, febrile vasculitis of unknown aetiology, which affects young children mainly under 5 years of age. The clinical variability has until now prevented to decrypt KD aetiological factors. Recently, the importance of genetics and the pivotal role of the immune system have emerged. To investigate in this direction, genomic DNA from 74 Caucasian KD cases and 440 healthy controls has been analysed to characterize functional polymorphisms of relevant HLA class III genes: AGER -429 and -374, TNF -857, -308 and -238, HSPA1A +190, HSPA1B +1267 and HSPA1L +2437. Allele, genotype and haplotype frequencies were therefore compared with the chi-squared test and Fisher's exact test. Our data showed significant deviations between patients with Kawasaki disease and controls concerning the TNF -308 polymorphism genotype (GG: P = 0.0449) and allele (G,A: P = 0.0433) and -238 polymorphism genotype frequencies (AA: P = 0.0351). Moreover, we found differences concerning the HSPA1A +190 polymorphism (GC: P = 0.0317) and the HSPA1L +2437 polymorphism (TT: P = 0.0072; TC: P = 0.0250; T: P = 0.0037; C: P = 0.0037). The calculation of TNF -238 and HSPA1L haplotype frequencies also pointed out a statistically significant decrease in patients of CG haplotype (P = 0.0001), which could have a role in protecting from the inflammatory processes that characterize the disease progression. The results obtained point to a possible involvement of the entire HLA class III region in KD susceptibility.International Journal of Immunogenetics 07/2013; · 1.36 Impact Factor
