Urine catecholamines in children with severe Enterovirus A71 infection: comparison with paediatric septic shock

AbstractPurpose: Hypercatecholaminemia-related heart failure has been proposed as the main cause of enterovirus A71-related (EV-A71) early mortality. The purpose of this study was to measure urine catecholamine concentrations in severe EV-A71-infected children.Methods: A total of 35 children, aged 2.5 ± 2.1 years, were divided into three groups. Group I: 15 septic shock patients, group II: 17 EV-A71-stage-2 patients, and group III: 3 EV-A71-stage-4 patients. The laboratory results, cardiac biomarkers and urine catecholamine concentrations were statistically analysed.Results: Group I had the highest C-reactive protein (CRP) levels and group II had the lowest B-type natriuretic peptide (BNP) and its N-terminal prohormone among the groups (p = 0.039, 134 ug/gCr, norepinephrine (NE) >176 ug/gCr and vanillylmandelic acid (VMA) >11.7 mg/gCr were used...
