Influence of lipids and obesity on haemorheological parameters in patients with deep vein thrombosis

SummaryIt is not well established whether haemorheological alterations constitute independent risk factors for deep vein thrombosis (DVT).We have determined in 149 DVT patients and in 185 control subjects the body mass index (BMI), the haemorheological profile: blood viscosity (BV), plasma viscosity (PV), fibrinogen (Fg), erythrocyte aggregation (EA), erythrocyte deformability (ED) and plasma lipids. In the crude analysis BMI, Fg, PV, EA, triglycerides (TG) and ApoB were statistically higher and HDL cholesterol (HDL-Chol) statistically lower in DVT patients than in controls. No differences in BV and ED were observed. After BMI adjustment, Fg, PV and EA remained statistically higher in DVT cases than in controls (P=0.013; P=0.012; P=0.013; P=0.028, respectively). When the risk of DVT associated with these variables (using cut-offs that corresponded to the mean plus one SD of the control group) was estimated, EA>8.2 and PV>1.28 mPa·s were significantly associated with DVT even further adjustment for lipids and obesity (OR=2.78, P=0.004; OR=1.91, P=0.024, respectively). However, PV did not remain statistically significant after additional adjustment for Fg. When we consider together all the analyzed variables in order to control every variable for each other, TG>175 mg/dl (OR=3,2,P=0.004) and BMI>30 kg/m2 (OR=3.5, P=0.003), were also independently associated with a greater risk of DVT. Our results suggest that increased EA constitute an independent risk factor for DVT. However, when associated to hyperlipidaemia and obesity it further increases thrombotic risk.

SummaryIn the present study 57 consecutive patients with a first episode of venographically proven deep vein thrombosis were investigated to evaluate the release of tissue-type plasminogen activator (t-PA) and of urokinase-type plasminogen activator (u-PA) in response to DDAVP stimulation as well as the resting plasminogen activator inhibitor (PAI) concentration, comparing this to the results obtained in 66 similar patients with a clinical suspicion of thrombosis but with a normal venogram. All assays were performed without knowledge of the patient's status.Four patients in the deep vein thrombosis-group (7%) had an absent u-PA antigen response upon DDAVP infusion, while a normal response was observed in all control subjects. Patients and controls showed similar increases in t-PA antigen level upon DDAVP. High resting PAI antigen levels were encountered in 5 patients in the deep vein thrombosis-group (9%) and in 6 subjects in the control group (9%).The results from this controlled study indicate that a defective release of u-PA may occur in patients with deep vein thrombosis and may have pathogenetic significance. Furthermore it is concluded that elevation of PAI levels cannot be considered as a specific risk factor for venous thrombosis.

SummaryTreatment with streptokinase (‘Kabikinase’) was given to 26 patients with venographically confirmed deep vein thrombosis extending into the popliteal vein or above. Treatment was continued for 4 days and the patients were allocated randomly to oral anticoagulant therapy or a course of treatment with ancrod (‘Arvin’) for 6 days followed by oral anticoagulant therapy. The degree of thrombolysis as judged by further venographic examination at 10 days was not significantly different between the 2 groups. The majority of patients showed clinical improvement but there was no appreciable difference between the groups at 3 and 6 months. Haemorrhagic complications were a more serious problem during the period of treatment with ancrod than during the equivalent period in the control group.

SummaryThe effect of subcutaneous low-dose heparin on postoperative deep-vein thrombosis (D. V. T.) (diagnosed by the 125I-labelled fibrinogen test) has been investigated in a trial of 143 patients undergoing the operation of total hip replacement. Two randomized studies were carried out: in one the scanning for D.V.T. was carried out daily for 7 days post operatively and in the other for 15 days. In both, the incidence of D.V.T. was significantly lower in the heparin-treated patients (P<0.005). Bilateral D.V.T. was also prevented (P<0.05), through the extension of D.V.T. to the distal veins of the thigh was not significantly reduced. Heparin treatment was, however, followed by a higher incidence of severe postoperative bleeding (P< 0.02) and wound haematoma formation (P< 0.005), and the postoperative haemoglobin was significantly lower than in the control group (P<0.005). A higher number of transfused blood units was also needed by the heparin treated patients (P<0.001).

Objective: Venous thromboembolism, including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common complaint in critically ill patients. Therefore, the present study was conducted to determine the effect of nursing interventions, based on the Wells results, on the incidence of DVT in intensive care unit (ICU) patients.Methods: The present clinical trial was conducted on 72 ICU patients without DVT and PE who met the inclusion criteria according to Wells score in Dr. Ganjavian Hospital, Dezful in 2012. The participants were investigated and randomly divided into intervention (n=36) and control groups (n=36). The intervention group received preventive nursing measures based on the risk level determined by the Wells score, and routine therapeutic interventions were performed for the control group. Then, patients were evaluated using Wells score, D-dimer testing, and Doppler sonography on the 1st, 5th, and 10th days. Data were finally coded and entered into SPSS version 23. Data analysis was performed using Chi-square, Fisher’s exact, and Mann–Whitney U tests.Results: The incidence of DVT in both groups showed that 2 patients of the control group who were identified to be at risk using the Wells score were diagnosed with DVT while none of the patients of the intervention group experienced DVT. The present study showed that 22.2% of the patients of the control group suffered from non-pitting edema, which was significantly different from the intervention group (p=0.005).Conclusion: The results of the present study showed that using the Wells score for early identification of the at-risk patients and nursing interventions based on this score’s results is helpful in the prevention of DVT. Appropriate nursing interventions were also effective in reducing the incidence of non-pitting edema in the lower extremities.

Background:There is limited published data on the association between malignancy and the location of venous thromboembolism (VTE) in the body. Aims:Assess the location of VTE in the body in patients with active cancer and compare these results in patients without malignancy. Methods:Consecutive patients enrolled in the Mayo Clinic VTE Registry between March 1, 2013 and November 30, 2019 for acute VTE were followed prospectively. Anatomical site of thrombosis and malignancy status were recorded. Patient outcomes were assessed in person, by mailed questionnaire, or by a scripted phone interview. Active cancer was defined as treatment for malignancy within the last six months or not yet in remission. Results:During the study period there were 2,798 patients with acute VTE (1256 with and 1542 without active cancer). Pulmonary emboli were more common in patients with active cancer compared to patients without cancer (49.5% vs. 39.7%, p<0.001). Upper extremity deep vein thrombosis (11.4 % vs. 7.7%, p<0.001), renal vein thrombi (1.4% vs. 0.2%, p<0.001) and splanchnic vein thrombi (9.3% vs. 6.0%, p=0.001) were all more common in patients with active cancer compared to patients without cancer. Conclusion:Compared to those without malignancy, patients with active cancer were more likely to have pulmonary emboli, upper extremity deep vein thrombosis, renal vein thrombi, and splanchnic vein thrombi.

Aim: Compare thrombotic risk in people with congenital hemophilia A (PwcHA) to the general non-hemophilia A (HA) population. Patients & methods: US claims databases were analyzed to identify PwcHA. Incidence rates of myocardial infarction, pulmonary embolism, ischemic stroke, deep vein thrombosis and device-related thrombosis were compared with a matched cohort without HA. Results: Over 3490 PwcHA were identified and 16,380 individuals matched. PwcHA had a similar incidence of myocardial infarction and pulmonary embolism compared with the non-HA population, but a slightly higher incidence of ischemic stroke and deep vein thrombosis. The incidence of device-related thrombosis was significantly higher in PwcHA. Conclusion: This analysis suggests that PwcHA are not protected against thrombosis, and provides context to evaluate thrombotic risk of HA treatments.

The prophylactic antithrombotic efficacy of a low molecular weight heparin was compared with a traditional unfractionated calcium heparin after orthopaedic surgery in 140 patients. Deep vein thromboses were detected in legs either by Doppler sonography or [125I]fibrinogen uptake tests in five (7.1%) and seven (10%) patients, respectively. The capacity of both drugs to prevent deep vein thrombosis was demonstrated. Compared with the control group, those who used low molecular weight heparin showed a significant increase of activated factor X inhibition and smaller increases in activated partial thromboplastin times. Tolerability of both drugs was good, with a low incidence of local side-effects.

Abstract Introduction: May-Thurner syndrome (MTS) is characterised by compression of the left external iliac vein by overriding right common iliac artery resulting in venous stasis. It carries a higher risk of left iliofemoral deep vein thrombosis (DVT), however the prevalence and management guidelines are unclear in pediatrics. We reviewed the prevalence of MTS in children diagnosed with left iliofemoral DVT at our center, associated prothrombotic risk factors and their clinical outcomes. Methods: This is a retrospective audit of pediatric patients (<18 years) with left iliofemoral DVT treated at the IWK Health Center from January 1 2008 to December 31 2020. Results: Twelve pediatric patients with left iliofemoral DVT were identified at our center and all patients except one had MRV/CTV during their course of anticoagulation to evaluate for MTS. MTS was diagnosed on imaging in 8 of the eleven evaluable patients with DVT and one patient had an incidental diagnosis of MTS with no DVT. The median age at diagnosis of MTS was 15 years (13-16), male:female ratio of 1:8. The overall prevalence rate was of MTS was 72.72% (8/11) in patients with left iliofemoral DVT. All patients with iliofemoral DVT and MTS had at least one other prothrombotic risk factor- initiation of estrogen containing contraceptive pills in the preceding 3 months of the DVT (n=5), inherited thrombophilia (n=2) and obesity (n=2). All patients with MTS were referred to vascular surgery. Only one patient required catheter directed thrombolysis and stenting at presentation of DVT, the remaining 7 patients were managed with anticoagulation alone. Complete (n=1) or partial (n=7) resolution of the thrombus was seen in all 8 patients. Median duration of follow up was 3 years. Recurrent DVT was seen in 1 patient and two patients came off anticoagulation at 6 months post therapy. Post thrombotic syndrome was seen in 4 patients, mild in 3 and moderate in 1; as per modified Villalta score. Conclusion: We observed a high prevalence of MTS in patients with left iliofemoral DVT which may be due our screening approachwith upfront radiographic evaluation for MTS in all patients with left iliofemoral DVT. A second pro-thrombotic risk factor was identified in all patients, which raises the possibility of a "two hit theory" for the occurrence of DVT in MTS. Compared to published adult studies, majority of our pediatric patients were managed conservatively with anticoagulation therapy alone. Disclosures No relevant conflicts of interest to declare.

Objective. To explore the effects of epidural anesthesia and general anesthesia on perioperative cognitive function and deep vein thrombosis (DVT) in patients undergoing total knee arthroplasty (TKA). Methods. Total of 68 patients undergoing TKA in our hospital from September 2019 to March 2021 were selected and divided into the control group under general anesthesia and the observation group under epidural anesthesia according to the different anesthesia methods, 34 patients in each group. TKA was selected in both groups and performed by the same group of physicians, anesthesiologists, and nursing staff. The mean arterial pressure (MAP), heart rate (HR), and blood oxygen saturation (SpO2) were observed immediately before anesthesia (T1), 30 min after anesthesia (T2), after surgery (T3), and 1 d after surgery (T4). The changes of platelet (PLC), fibrinogen (Fbg), prothrombin time (PT), activated partial thrombin time (APTT), and other coagulation indicators were recorded. The Montreal Cognitive Assessment (MoCA) scores before surgery and 1 d and 3 d after surgery were observed. The blood samples of the two groups were collected before surgery and 1 d and 3 d after surgery, and the levels of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in the peripheral blood of the two groups were measured by ELISA. The number of postoperative mental disorders and DVT in the two groups was calculated. Results. The MAP and HR of T4 were lower than those of T1, T2, and T3. The MAP of T2, T3, and T4 in the observation group was lower than that in the control group ( P < 0.05 ), and the SpO2 of T1–T4 in the two groups did not change significantly, and there was no significant difference between the two groups ( P > 0.05 ). Compared with T1, there was no significant difference in PLC, Fbg, and PT in the observation group T4 ( P > 0.05 ), and APTT was lower than T1 ( P < 0.05 ). The PLC, PT, and APTT of T4 in the control group were all lower than those of T1 ( P < 0.05 ), and there was no significant difference between Fbg and T1 ( P > 0.05 ). The PLC, Fbg, and PT of T4 in the observation group were higher than those in the control group, while APTT was lower than that in the control group ( P < 0.05 ). The MoCA scores of patients in both groups on the 1st and 3rd day after operation were lower than those before operation, and the observation group was higher than that in the control group ( P < 0.05 ). The BDNF and NGF of patients in both groups were lower than those before operation on the 1st day after operation, and the BDNF and NGF in the observation group were higher than those in the control group on the 1st and 3rd day after operation ( P < 0.05 ). The mental disorder (2.94%) and DVT incidence (2.94%) in the observation group were lower than those in the control group (29.41%, 26.47%) ( P < 0.05 ). Conclusion. Epidural anesthesia for patients with TKA can obtain better clinical effects, maintain stable hemodynamic and coagulation states, reduce stress response of patients at the same time, and reduce perioperative cognitive dysfunction and the incidence of DVT in patients.
