ABSTRACT
Objective:
To explore the prognostic values of peripheral blood cell parameters neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and mean platelet volume-to-lymphocyte ratio (MPVLR) in children under the age of 4 years with infection-associated hemophagocytic syndrome (IAHS).Methods:
The clinical data of 70 children under the age of 4 years with IAHS treated in the First Affiliated Hospital of Zhengzhou University from January 2015 to October 2020 were analyzed retrospectively, including the changes in peripheral blood cell parameters at the time of diagnosis, and 2, 4 and 8 weeks after treatment. Mann- Whitney U test was used to compare the differences in peripheral blood cell parameters of IAHS children with different prognosis statues.The prognostic values of NLR, PLR and MPVLR were evaluated by plotting receiver operating characteristic (ROC) curves.The optimal cut-off value was determined by Youden index.Children were grouped according to the optimal cut-off values of NLR, PLR and MPVLR.The survival rate was estimated by Kaplan-Meier method, followed by Log- rank test for pairwise comparison.Results:
(1)Compared with the survival group, NLR, PLR and MPVLR were significantly higher at the diagnosis in the death group(all P<0.001). (2)ROC curves showed that the area under the curve(AUC) of NLR, PLR and MPVLR to predict the prognosis of children with IAHS were 0.805, 0.815 and 0.772, respectively.When the optimal cut-off value of NLR, PLR and MPVLR were 0.73, 32.86 and 14.19, respectively, the sensitivity and specificity were 69.57% and 89.36%, 86.96% and 68.09%, and 60.87% and 89.36%, respectively.(3)According to the optimal cut-off value, the total survival time of children in NLR>0.73 group was significantly shorter than that in NLR ≤ 0.73 group, and that of children in PLR>32.86 group was significantly shorter than that in PLR ≤ 32.86 group; the total survival time of children in MPVLR>14.19 group was significantly shorter than that in MPVLR ≤ 14.19 group(all P<0.001). (4)After 2 weeks of treatment, the NLR and MPVLR in the death group were significantly higher than those in the survival group(all P<0.05). After 2, 4 and 8 weeks of treatment, NLR, PLR and MPVLR in the survival group were significantly improved as compared with those at the diagnosis(all P<0.05), but there was no significant change in the death group(all P>0.05).Conclusions:
NLR, PLR and MPVLR at the time of diagnosis have a certain predictive value for the prognosis of children under the age of 4 years with IAHS.Monitoring their changes in the early stage of treatment is helpful to judge the prognosis.
