Abstract

To evaluate the clinical value of aquaporin-4 (AQP-4) in hand, foot, and mouth disease (HFMD) and to evaluate therapeutic efficacy of magnesium sulfate (MgSO4) and its effect on AQP-4 expression. Children with HFMD were divided into a common group, a severe group and a critical group according to Chinese guidelines; children in the critical group were further divided into two subgroups: routine treatment group and MgSO4 group. Outcome measures included systolic blood pressure (SBP), Heart rate (HR), the levels of AQP-4, interleukin-6 (IL-6), norepinephrine (NE), and neuron-specific enolase (NSE). Serum AQP-4, IL-6, NE, and NSE levels varied significantly among the critical, severe, and common groups before and after treatment. There were no significant differences in AQP-4 levels in cerebrospinal fluid (CSF) between the critical and severe groups before and after treatment; however, CSF AQP-4 levels in these two groups were higher than those in the common group before treatment. Serum and CSF AQP-4 levels in convalescence decreased significantly in the critical and severe groups. SBP, HR and serum AQP-4, IL-6, NE, NSE levels, but not CSF AQP-4 levels, were significantly lower in MgSO4 group than in the routine treatment group. AQP-4 in serum, but not in CSF, is a candidate biomarker for evaluating the severity and prognosis of HFMD; MgSO4 can provide protection on children with critical HFMD.
