Evidential Basis

Venous thromboembolic complications (VTEC) are acute and time-limited diseases. However, the recurrence rate after a first episode of VTEC is high and potentially life-threatening. Developed deep vein thrombosis (DVT) and thromboembolism of pulmonary artery (TEPA) are inevitably associated with use of anticoagulant therapy (ACT). A peculiarity of the modern clinical management of patients with VTEC is determination of duration of ACT. Aim. To study possibilities of prolonged anticoagulation therapy and secondary prevention of venous thromboembolic complications taking into consideration modern variants of drug therapy, on the basis of literature data. Search for literature was conducted in Medline and Elibrary databases including materials published in 2020. Randomized clinical and observational studies and meta-analyses, concerning prolonged therapy and secondary prevention of VTEC with vitamin K antagonists (VKA), peroral anticoagulants (POAC), sulodexide and aspirin, were analyzed. As it is evidenced by patho-physiological and epidemiological data, risk of VTEC recurrence in most patients is not resolved after the first 6 months of treatment with anticoagulants. In such situations it is reasonable to prolong anticoagulation for an indefinite period of time. However, sometimes a limiting factor for prolonged therapy with anticoagulants is bleedings caused by prolonged anticoagulation, sometimes leading to lethal outcome. Therefore, duration of treatment in the long-term period after an acute episode may rest on the balance between the risk of development of recurrence of venous thrombosis and bleeding, evaluated with the help of scales. The main achievement of recent years regarding prolonged therapy and secondary prevention of VTEC, are POAC, which in fact are new and alternative drugs that permitted the emergence of serious evidential basis in the range of means for treatment of this category of patients, sulodexide drug has appeared characterized by the minimal rate of development of large and clinically significant bleedings. Conclusion. The emergence of serious evidential basis for POAC with improved safety profiles, different pharmacokinetic profiles and dosage regimens, including sulodexide that has been actively used in recent years for secondary prevention of VTEC, will permit clinicians to differentially approach treatment of different clinical variants of venous thrombosis, to improve the results of therapy taking into account evaluation of the individual risk and comorbid diseases, and compliance of patients.

Abstract Carriers of a mutation in the prothrombin (clotting factor II) or factor V gene have a 2- to 4-fold greater risk for venous thromboembolism than subjects without the mutations. Whether both mutations also predispose to recurrent venous thromboembolism is unclear. Outpatients who had a first episode of proven symptomatic deep-vein thrombosis and a long-term follow-up were studied. The outcome measure was the cumulative incidence of confirmed venous thromboembolic complications. Two hundred fifty-one patients were enrolled in the study. Mean duration of follow-up was 8.3 years. The prothrombin gene mutation was demonstrated in 27 patients (prevalence, 10.8%; 95% CI, 6.9 to 14.6), and the factor V gene mutation was demonstrated in 41 patients (prevalence, 16.3%; 95% CI, 11.8 to 20.9). The cumulative incidence of venous thromboembolic complications after 10 years was 61.3% (95% CI, 35.7 to 87.9), and the hazard ratio was 2.4 (95% CI, 1.3 to 4.7; P = .004) in patients with the prothrombin gene mutation); the cumulative incidence of venous thromboembolic complications after 10 years was 55.2% (95% CI, 36.4 to 74.0), and the hazard ratio was 2.4 (95% CI, 1.4 to 4.1;P = .001) in patients with the factor V gene mutation. In comparison, the cumulative incidence of venous thromboembolic complications after 10 years was 23.1% (95% CI, 16.2 to 30.1) in patients without the mutations. Prothrombin and factor V gene mutations occur frequently in patients with venous thrombosis and are associated with an increased risk for recurrent venous thromboembolic complications

Optimal Duration

Clinical practice guidelines currently suggest extended anticoagulation therapy for primary and secondary prevention of venous thromboembolism (VTE). The optimal duration of anticoagulation has been an active area of clinical investigation for patients undergoing orthopedic surgeries and those diagnosed with a first episode of unprovoked VTE. Practice guidelines, VTE incidence, clinical predictors/mediators, and clinical trial evidence is reviewed to help pharmacists and other health care providers make an informed, patient-specific decision on the optimal duration of anticoagulation therapy. Extended anticoagulation up to 5 weeks following orthopedic surgery for primary VTE prevention and indefinitely following a first episode of unprovoked VTE for secondary VTE prevention should be considered only if the risk of bleeding is not high and the cost and burden of anticoagulation is acceptable to the patient. The optimal duration of anticoagulation therapy for primary or secondary prevention of VTE should include the health care provider and patient making a decision based on evaluation of individual benefits, risks, and preferences.

Oncological patients are a high-risk group for venous thromboembolic complications. These complications significantly impair the outcome of antitumor treatment and take a leading place in the structure of mortality. Treatment of venous thromboembolic complications in oncological patients is a serious challenge. When selecting an anticoagulant, the physician should consider its efficacy and safety and possible drug interactions. Based on results of multiple studies presented in this article, physicians will be able to choose an optimum therapeutic tactics and secondary prevention of thromboembolic complications for this group of patients.

A Prospective Study

SummaryPostoperative venous thromboembolic complications are commonly seen after total replacement of the hip or knee. Recently, an inherited defect with resistance to the anticoagulant activity of activated protein C (APC-resistance) has been detected. APC-resistance seems to be a common risk factor, especially in Sweden, and it increases the propensity for venous thrombosis. This study assesses the prevalence of APC-resistance in a general population and its clinical significance for patients undergoing surgery associated with a high risk of thromboembolic complications. In a prospective cohort study, we analysed for APC-resistance in 645 consecutive patients before elective replacement of the hip or knee at 3 hospitals in southern Sweden. Thromboprophylaxis with LMWH-heparin was given to all patients throughout the hospitalisation period. We recorded events of clinical thromboembolism for 3 months postoperatively. Venography, ultrasonography or pulmonary scintigraphy was requested by the clinicians according to the existing routines, i.e. only patients with symptoms of thromboembolism were examined. A thromboembolic complication was registered in 20 (3.1%) patients. Fifty per cent of the venous thrombi had a proximal location. Only 0.3% of the patients had verified pulmonary embolism. APC-resistance was found in 14.1% of the patients, of whom 9.9% had experienced postoperative thromboembolism compared with 2.0% of the patients without APC-resistance (p <0.0007). We conclude that APC-resistance is a frequent risk factor for symptomatic postoperative deep venous thrombosis with an estimated relative risk of 5.0 (95% confidence interval: from 1.9 to 12.9) in elective replacement of the hip or knee.

Abstract Purpose of review Describe the role of inferior vena cava filter (IVCF) retrieval in patients on chronic anticoagulation given the overlap of these treatment options in the management of patients with venous thromboembolic disease. Recent findings Despite the increase in IVCF retrievals since the Food and Drug Administration safety communications in 2010 and 2014, retrieval rates remain low. Previous studies have shown that longer filter dwell times are associated with greater risk for filter complications and more difficulty with filter retrievals. Recent findings suggest that complications are more frequent in the first 30 days after placement. Summary The decision to retrieve an optional IVCF is individualized and requires diligent follow-up with consistent re-evaluation of the need for the indwelling IVCF, particularly in those on long-term anticoagulation therapy.

Objective: To evaluate the association between the Factor V Leiden (FV R506Q) and prothrombin gene (FII G20210A) mutations and deep venous thrombosis (DVT) in young people. Methods: Blood samples were drawn from 199 subjects: 100 healthy controls and 99 unselected patients, with an objectively documented first episode of DVT under 40 years old. DNA analysis was performed using the polymerase chain reaction. Results: The mean age in the patient cohort was 27 years (range 16–40) and 68 (68.7%) were women. Patient prevalences were 20.6% and 10.1% for FV R506Q and FII G20210A, respectively. In the control group, carrier frequencies were 2% and 5%, respectively. We found an increased overall relative risk of DVT with statistical significance for FV R506Q carriers (OR: 12.8; 95% CI: 2.9–56.7; P < 0.001), but not for FII G20210A mutation (OR: 2.1; 95% CI: 0.7–6.5; P = 0.19). Conclusions: Our results suggest a possible increase in DVT risk for the young G20210A allele carriers, which can be more expressed in the presence of a circumstantial risk factor. There is extremely strong evidence that the Factor V Leiden mutation is an important risk factor in the development of a first episode of DVT in young people.
