OBJECTIVE: To study the value of serum S100B protein and neuron-specific enolase (NSE) levels in predicting the severity of hand, foot and mouth disease (HFMD).
METHODS: Ninety children with HFMD were classified into three groups: common type, severe type, and critical type (n=30 each). Thirty healthy children were randomly selected as the control group. ELISA was used to measure serum levels of S100B protein and NSE before and at 7 days after treatment. The receiver operating characteristic (ROC) curve was used to evaluate the prediction efficiency of S100B protein and NSE for the severity of HFMD.
RESULTS: The critical type group had significant increases in the serum levels of S100B protein and NSE compared with the other three groups (P<0.01). The severe type group had significant increases in serum levels of S100B protein and NSE compared with the common type and control groups (P<0.01). The critical type and severe type groups had significant reductions in serum levels of S100B protein and NSE after treatment (P<0.05). Serum S100B protein had the highest Youden value of 0.611 at the cut-off value of 0.445 μg/L, with a sensitivity of 61% and a specificity of 100%, in the prediction of serious HFMD (including severe type and critical type HFMD). Serum NSE had the highest Youden value of 0.533 at the cut-off value of 5.905 μg/L, with a sensitivity of 80% and a specificity of 73%, in the prediction of serious HFMD. Combined measurements of these two parameters had a sensitivity of 86% and a specificity of 73% and had the highest predictive value for serious HFMD.
CONCLUSIONS: The serum levels of S100B protein and NSE help to predict the severity and treatment outcomes of HFMD. Combined measurements of these two parameters has a higher predictive value for serious HFMD.
