Abstract:
Objective:To investigate the related risk factors affecting the prognosis of hemorrhagic fever with renal syndrome(HFRS) in children.Methods:A retrospective study was carried out.We selected 182 pediatric patients who met the diagnostic criteria for pediatric HFRS while hospitalized in the Intensive Care Department of the Affiliated Children′s Hospital of Xi′an Jiaotong University between July 2014 and December 2021 as the research objects.The severe and critical patients were taken as the observation group(24 cases), and the mild and moderate pediatric patients were taken as the control group(158 cases). The demographic, epidemiological data and clinically relevant indicators within 8 hours of pediatric patients after admission were collected.The 28-day death was the primary endpoint.Renal failure and pulmonary edema were secondary endpoint.The differences of clinically relevant indicators between the two groups were observed.Logistic regression was used to analyze the risk factors and receiver operating characteristic(ROC) curve was used to determine the predictive efficacy of different outcome prediction models.Results:There were no statistically significant differences in age, gender, and BMI between the two groups (all P>0.05). Compared the control group with the observation group, coagulation function indicators such as activated partial thromboplastin time (APTT)[(134±21)s vs.(164±34)s], D-dimer [(6.31±3.20)mg/L vs.(12.43±5.67)mg/L], von Willebrand factor (vWF)[(352±45)μg/L vs.(465±103)μg/L], and platelet(PLT)[(87±35)×10 9/L vs.(45±24)×10 9/L], Lactate(Lac)[(2.6±1.1)mmol/L vs.(6.0±2.0)mmol/L]were different significantly(all P<0.05). Additionally, the lymphocyte characteristic analysis indicator lymphocytes [(2 749±686)×10 6/L vs.(2 374±851)×10 6/L], CD3 + [(1 821± 487)×10 6/L vs.(1 065±539)×10 6/L], CD4 + /CD8 + (1.65±0.73)vs.(1.00±0.25), CD19 + [(559±105)×10 6/L vs.(487± 133)×10 6/L]were different significantly(all P<0.05). The inflammatory index procalcitonin(PCT) [(22±15)ng/L vs.(56±21)ng/L, P<0.05]was different significantly in two groups.The rate of continuous renaly replacement therapy, ventilator-assisted ventilation, vasoactive drugs and other treatment measures increased significantly in observation group than those in control group(all P<0.05). Multivariate logistic regression analysis was performed on the included indicators.With death as the primary endpoint, Lac, CD8 + , D-dimer, vWF and PCT were significantly associated with mortality, which were risk factors for death, while PLT and CD4 + /CD8 + were protective factors.With renal failure and pulmonary edema as secondary endpoint, CD8 + , D-dimer, Lac and PCT were risk factors for secondary endpoint.ROC curve analysis showed that the sensitivity, specificity and AUC of the risk factor prediction model related to the primary endpoint variables were 77.91%, 81.22% and 0.769, and which related to secondary endpoint variables were 87.61%, 77.59% and 0.891, respectively. Conclusion:The combinations of CD8 + , D-dimer, Lac, PCT and vWF have good predictive value for poor prognosis in children with HFRS.
