Correlation between neutrophil to lymphocyte ratio and clinical features of cerebral venous sinus thrombosis / 国际脑血管病杂志

ABSTRACT

Objective:To investigate the neutrophil to lymphocyte ratio (NLR) and clinical manifestations, imaging manifestations and plasma D-dimer in cerebral venous sinus thrombosis (CVST) patients with headache as the first symptom.Methods:CVST inpatients with headache as the first symptom admitted to the First Affiliated Hospital of Nanjing Medical University from January 2012 to December 2019 were enrolled retrospectively as case group. In the same period, patients with similar headache symptoms and healthy subjects were included consecutively as control group. The differences of demographic data, biochemical indexes, blood routine indexes and plasma D-dimer were compared among the three groups. Multivariate logistic regression analysis was used to identify the independent correlation between NLR and plasma D-dimer and CVST with headache as the first symptom. According to the median NLR, patients with CVST were divided into low NLR group and high NLR group, and the differences in clinical manifestations, imaging manifestations and plasma D-dimer were compared between the two groups. Multiple linear regression analysis was used to determine the independent correlation between the reciprocal of NLR and plasma D-dimer and clinical features. Results:A total of 51 CVST inpatients with headache as the first symptom, 54 headache controls and 53 healthy controls were included in the study. There were significant differences in triglyceride ( P=0.002), fasting blood glucose ( P=0.044), serum albumin ( P=0.013), uric acid ( P=0.010), plasma D-dimer ( P<0.001), proportion of D-dimer negative patients ( P<0.001), mean corpuscular volume ( P=0.015), white blood cell count ( P<0.001), neutrophil count ( P<0.001), lymphocyte count ( P=0.005), monocyte count ( P=0.004), mean platelet volume ( P=0.010), platelet distribution width ( P=0.029), NLR ( P<0.001) and lymphocyte to monocyte ratio ( P<0.001) among the three groups. Post-hoc analysis showed that plasma D-dimer and NLR in the case group were significantly higher than those in the two control groups (all P<0.001). Multivariate logistic regression analysis with the headache control group and the healthy control group as references showed that NLR and plasma D-dimer were significantly and independently correlated with CVST with headache as the first symptom (all P<0.05). According to the median NLR (4.817 6), the case group was divided into low NLR group and high NLR group. The comparison showed that the onset time ( P=0.041), the proportion of patients with headache as the only symptom ( P=0.016) and the proportion of plasma D-dimer negative patients ( P=0.002) in the low NLR group were significantly higher than those of the high NLR group, and the proportion of patients with headache complicated with disturbance of consciousness ( P=0.032), plasma D-dimer ( P<0.001) and fasting blood glucose ( P<0.001) were significantly lower than those in the high NLR group. With the reciprocal of NLR as the dependent variable, multiple linear regression analysis showed that the reciprocal of NLR was independently negatively correlated with plasma D-dimer ( R=-0.521, P<0.001), and independently positively correlated with headache as the only symptom ( R=0.280, P=0.049). Conclusions:NLR was significantly increased in CVST patients with headache as the first symptom. It might help early diagnosis and clinical feature prediction of CVST patients.
