Diagnosis effect of thrombelastography in chronic kidney disease

Abstract

Objective To discuss the diagnosis effect and clinical significance of thrombelastography in chronic kidney disease. Methods From June 2016 to February 2017, two hundred and seventy non-dialysis patients with chronic kidney disease (CKD) treated in the Fourth Hospital of Hebei Medical University were divided into non-hypercoagulable group and hypercoagulable group according to TEG comprehensive coagulation index.The changes of related clinical indexes between the two groups were analyzed and the related factors affecting the differences between the two groups were studied. Results The correlation between the two groups showed that the coagulation reaction time (R), coagulation formation time (K) and albumin in the hypercoagulable group were significantly lower than those in the non-hypercoagulable group ((4.69±0.94) min vs.(6.29±1.63) min, (0.93±0.13) min vs.(1.51±0.58) min, (27.54±7.81) g/L vs.(34.26±8.39) g/L, P=0.000) Angle angle, maximum thrombus strength (MA), fibrinogen, D-dimer, platelet count, protein/creatinine and protein content in hypercoagulable group were significantly higher than those in non-hypercoagulable group((76.76±2.23)°vs.(68.19±7.65)°; (75.13±3.81)mm vs.(66.35±7.81)mm; (4.28±0.93) g/L vs.(3.56±1.10) g/L ; 0.4(0.15, 0.91) mg/L vs.0.22(0.12, 0.52) mg/L; (276.03±127.15)×109/L vs.(198.18±78.46)×109/L; 5 430(2 579, 9 634) mg vs.2 620(692, 5 286) mg; 4 864(2 341, 7 712) mg/g vs.2 557(840, 5 805) mg/g, P 0.05). Correlation analysis of common clinical indicators showed that the comprehensive coagulation index (CI) was positively correlated with Angle angle, maximum thrombus strength, fibrinogen, platelet count, protein/creatinine and protein quantification (r=0.532, 0.522, 0.307, 0.354, 0.293, 0.216, P<0.05), was negatively correlated with coagulation reaction time, coagulation formation time and albumin (r=- 0.462, - 0.496, - 0.360, P<0.05). Logistic regression analysis showed that platelet count, albumin and fibrinogen were the influencing factors for the grouping of comprehensive coagulation index (OR (95%CI) : 1.007 (1.002-1.013), 0.868 (0.827-0.912), 1.510 (1.042-2.187), P<0.05). Conclusion TEG is a more sensitive indicator to reflect the coagulation status of patients with CKD, and has a certain guiding significance for anticoagulation treatment of patients with CKD; platelet count, albumin, fibrinogen are the factors affecting coagulation function of patients.
