Abstract:
Objective:To investigate the expression and clinical significance of Beclin-1 and cytochromes C (CytC) in patients with hand, foot and mouth disease (HFMD).Methods:Sixty children with HFMD were classified into two groups of severe group and common group with 30 cases in each group. Another thirty children who underwent circumcision and had no underlying disease were selected as control group. Serum Beclin-1, CytC and S100B levels were detected before and after treatment. The levels of Beclin-1 and CytC in cerebrospinal fluid (CSF) of children with severe HFMD were detected before and after treatment. Receiver operating characteristic (ROC) curve was used to evaluate the prediction efficiency of Beclin-1 and CytC for the severity of HFMD.Results:Serum Beclin-1 and CytC levels in the severe group were higher than those in the other two groups ( P<0.01), and the common group showed significantly increased serum Beclin-1 and CytC levels as compared with the control group ( P<0.01). After treatment, the serum Beclin-1 and CytC levels decreased in both severe and common groups ( P<0.05). Compared with the common group, the severe group had remarkable increases in the levels of Beclin-1 and CytC in CSF ( P<0.01), which decreased significantly after treatment ( P<0.01). Serum Beclin-1 and CytC levels were positively correlated with the level of S100B protein. In the prediction of severe HFMD, serum CytC had the highest Youden value of 0.533 at the cut-off value of 38.785 ng/ml with a sensitivity of 56.67% and a specificity of 96.67%; serum Beclin-1 had the highest Youden value of 0.467 at the cut-off value of 6.560 ng/ml with a sensitivity of 46.67% and a specificity of 100.00%. Combined measurements of these two parameters had the highest predictive value for severe HFMD with a sensitivity of 76.67% and a specificity of 96.67%. Conclusions:Serum Beclin-1 and CytC levels were conducive to predict the severity and treatment outcomes of HFMD. Combined measurements of these two parameters had a higher predictive value for severe HFMD.
