However, the exact relationship between coagulopathy and PHI remains unclear. The present study utilized a scoring system defined by the International Society of Thrombosis and Haemostasis to investigate whether a high DIC score is predictive for PHI. This study was a multicenter prospective design involving four hospitals, a 6-month observation, and follow-up. Of 352 traumatic brain injury （TBI） patients, serial CT scan indicated approximately one third of patients developed progressive hemorrhage, which was most frequently observed in the frontal, temporal, and orbitofrontal lobes of patients with brain contusion. PHI-positive patients exhibited poor prognosis, as indicated by prolonged length of hospital/intensive care unit stay and high mortality. More importantly, a DIC score after TBI, as well as patient age and sex, could serve as predictors for PHI. In addition, DIC scores were closely associated with injury severity. Therefore, the DIC scoring system facilitated early PHI diagnosis in TBI patients, and DIC scores might serve as a valuable predictor for TBI patients with PHI.展开更多

Among the morphological varieties of Acute Myeloid Leukaemia (AML), Acute Promyelocytic Leukaemia (APL) is well established to cause DIC. But there have been reports noted that abnormal DIC parameters also commonly observed in the patients with non-APL AML. This study evaluated the DIC parameters & DIC score according to International Society of Thrombosis and Haemostasis (ISTH) in newly diagnosed non-APL AML patients. <strong>Materials and Methods:</strong> This cross-sectional observational study was conducted in the Department of Haematology, BSMMU, Dhaka, Bangladesh. 48 newly diagnosed non-APL AML patients were enrolled. Platelets count was measured by auto analyzer (Sysmax XT 2000i/Pentra ABX-120DX) as well as checked manually. Prothrombin time, fibrinogen, D-Dimer were measured using STAGO Coagulation analyzer. The ISTH-DIC scoring system was used to calculate DIC score. The statistical analysis was carried out using the Statistical Package for Social Sciences version 24.0 for Windows. Chi-Square test & Fisher exact test was used for categorical variables. Unpaired t-test was used to compare mean between groups. For all statistical tests, p-value less than 0.05 was considered as statistically significant. <strong>Results: </strong>By analyzing 48 newly diagnosed patients with non-APL AML, found that DIC developed in 14.6% patients at presentation. Among the DIC parameters, PT and D-dimer were significantly higher in patients presented with DIC. Patients with DIC exhibit lower expression of CD117, CD34, HLA-DR and statistically significant association with negative expression of HLA-DR (p-value 0.034). No significant association was found between presence of DIC and age, gender, bleeding at presentation, morphological type, WBC count or peripheral blast percentage.<strong> Conclusion:</strong> Abnormalities of DIC parameters in common in patients with AML. A significant portion of patients with DIC have no apparent symptom or bleeding. So, routine screening of DIC parameter at presentation is recommended for early diagnosis & effective management of DIC.展开更多
