[Clinical- epidemiological characteristics and predictors of coronary complications in children of Argentina with Kawasaki disease]. / Características clínico-epidemiológicas y predictores de complicaciones coronarias en niños de Argentina con enfermedad de Kawasaki.

ABSTRACT

BACKGROUND: Kawasaki disease (EK) is an acute systemic vasculitis with a risk of developing coronary aneurysms. AIM: To describe the clinical and epidemiological characteristics of children with EK in Argentina and to analyse the risk factors for the development of coronary's complications (CC). METHODS: Multicenter, retrospective, cross-sectional, observational and analytical study. It included patients younger than 18 years of age diagnosed with EK in hospitals in Argentina, between January the 1st, 2010 and December the 31th, 2013. RESULTS: N = 193 subjects. Age medium 29 months. Total incidence 5 cases / 10,000 hospital discharges. CC was observed in 15.5% of patients. Increased risk factors for CC Elevated number of days with fever at the time of treatment placement (p = 0.0033); Increased of heart frequency (p = 0.0021), erythrosedimentation (ESR) (p = 0.005), C-reactive protein (CRP) (p < 0.0001), leukocytes (p = 0.0006), neutrophils (p = 0.0021); Decreased of hematocrit (p = 0.0007) and hemoglobin (p < 0.0001).Association with CC non-coronary cardiological alterations (OR = 10,818); PCR greater than 68 mg /L (OR = 11,596); leukocytes greater than 20,000 / mm3 (OR = 4.316); and ESR greater than 64 mm / 1 hour (OR = 4.267). CONCLUSION: The most frequent form of presentation was complete EK, the risk of CC was higher in males, younger than 5 years old, the risk factors (clinical and laboratory) were similar to those described in the literature.
