Venous thromboembolism (VTE) is a chronic rather than acute disease. After withdrawal of secondary thromboprophylaxis, many patients will experience a subsequent episode of thrombosis. Of these patients, approximately 5% will die from pulmonary embolism. The risk of recurrent VTE depends on the number of risk factors and their severity. High-risk patients, i.e. those with a natural coagulation inhibitor deficiency, recurrent thrombosis, active cancer, the lupus anticoagulant or compound clotting defects most probably benefit from indefinite oral anticoagulation. In these patients the risk of bleeding due to anticoagulant treatment seems to be outweighed by the risk of VTE. Patients with hyperhomocysteinemia or high factor (F) VIII plasma levels are also at an increased risk of recurrence. The optimal duration of secondary thromboprophylaxis in these patients is currently under investigation. Patients with the heterozygous F V Leiden mutation or the G20210A mutation in the F II gene do not require extended anticoagulation since their risk of recurrence is similar as in patients without the aforementioned mutations. Patients with VTE secondary to surgery or trauma have a relatively low risk of recurrence. In these patients short-term secondary thromboprophylaxis (6 to 12 weeks) is justified whereas patients with a first episode of spontaneous VTE should be treated with oral anticoagulants for a longer period of time (3 to 6 months).

The Impact

Abstract. Background: Whether screening for thrombophilia is useful for patients after a first episode of venous thromboembolism (VTE) is a controversial issue. However, the impact of thrombophilia on the risk of recurrence may vary depending on the patient’s age at the time of the first VTE. Patients and methods: Of 1221 VTE patients (42 % males) registered in the MAISTHRO (MAin-ISar-THROmbosis) registry, 261 experienced VTE recurrence during a 5-year follow-up after the discontinuation of anticoagulant therapy. Results: Thrombophilia was more common among patients with VTE recurrence than those without (58.6 % vs. 50.3 %; p = 0.017). Stratifying patients by the age at the time of their initial VTE, Cox proportional hazards analyses adjusted for age, sex and the presence or absence of established risk factors revealed a heterozygous prothrombin (PT) G20210A mutation (hazard ratio (HR) 2.65; 95 %-confidence interval (CI) 1.71 - 4.12; p < 0.001), homozygosity/double heterozygosity for the factor V Leiden and/or PT mutation (HR 2.35; 95 %-CI 1.09 - 5.07, p = 0.030), and an antithrombin deficiency (HR 2.12; 95 %-CI 1.12 - 4.10; p = 0.021) to predict recurrent VTE in patients aged 40 years or older, whereas lupus anticoagulants (HR 3.05; 95%-CI 1.40 - 6.66; p = 0.005) increased the risk of recurrence in younger patients. Subgroup analyses revealed an increased risk of recurrence for a heterozygous factor V Leiden mutation only in young females without hormonal treatment whereas the predictive value of a heterozygous PT mutation was restricted to males over the age of 40 years. Conclusions: Our data do not support a preference of younger patients for thrombophilia testing after a first venous thromboembolic event.

AbstractAtrial fibrillation (AF) is commonly diagnosed in the setting of active cancer. Because of an increased risk of either thromboembolic events or bleeding, the decision to initiate therapeutic anticoagulation in patients with active cancer can be challenging. Moreover, little is still known about the optimal anticoagulation therapy in the setting of AF and cancer, and no guidelines are as yet available. Considering that nonvitamin K antagonist oral anticoagulants (NOACs) are recommended as alternatives to vitamin K antagonists for stroke prevention in AF patients with CHA2DS2-VASc score ≥2, the authors performed a systematic review of the current literature to describe the efficacy and safety of NOACs in AF patients with malignancy.

<b><i>Objective:</i></b> Our study aimed to analyse temporal trends in radioactive iodine (RAI) treatment for thyroid cancer over the past decade; to analyse key factors associated with clinical decisions in RAI dosing; and to confirm lower activities of RAI for low-risk patients were not associated with an increased risk of recurrence. <b><i>Methods:</i></b> Retrospective analysis of 1,323 patients who received RAI at a quaternary centre in Australia between 2008 and 2018 was performed. Prospectively collected data included age, gender, histology, and American Joint Committee on Cancer stage (7th ed). American Thyroid Association risk was calculated retrospectively. <b><i>Results:</i></b> The median activities of RAI administered to low-risk patients decreased from 3.85 GBq (104 mCi) in 2008–2016 to 2.0 GBq (54 mCi) in 2017–2018. The principal driver of this change was an increased use of 1 GBq (27 mCi) from 1.3% of prescriptions in 2008–2011 to 18.5% in 2017–2018. In patients assigned as low risk per ATA stratification, lower activities of 1 GBq or 2 GBq (27 mCi or 54 mCi) were not associated with an increased risk of recurrence. In patients assigned to intermediate- or high-risk categories who received RAI as adjuvant therapy, there was no difference in risk of recurrence between 4 GBq (108 mCi) and 6 GBq (162 mCi). <b><i>Conclusions:</i></b> Our data demonstrate an evolution of RAI activities consistent with translation of ATA guidelines into clinical practice. Use of lower RAI activities was not associated with an increase in recurrence in low-risk thyroid cancer patients. Our data also suggest lower RAI activities may be as efficacious for adjuvant therapy in intermediate- and high-risk patients.

Abstract Aim To determine to what extent active cancer influences the benefit–risk relationship among patients with atrial fibrillation receiving oral anticoagulants for stroke prevention. Methods In this cohort study of all patients with atrial fibrillation in the Swedish Patient register during 2006 to 2017, 8,228 patients with active cancer and 323,394 without cancer were followed up to 1 year after initiation of oral anticoagulants. Cox regression models, adjusting for confounders and the competing risk of death, were used to assess risk of cerebrovascular and bleeding events. Results Among patients treated with oral anticoagulants, the risk for cerebrovascular events did not differ between cancer patients and noncancer patients (subhazard ratio [sHR]: 1.12, 95% confidence interval [CI]: 0.98–1.29). Cancer patients had a higher risk for bleedings (sHR: 1.69, CI: 1.56–1.82), but not for fatal bleedings (sHR: 1.17, CI: 0.80–1.70). Use of nonvitamin K oral anticoagulants was associated with lower risk of both cerebrovascular events and bleedings compared with warfarin. Conclusion Patients with atrial fibrillation and active cancer appear to have similar net cerebrovascular benefit of oral anticoagulant treatment to patients without cancer, despite an increased risk of nonfatal bleedings. Use of nonvitamin K oral anticoagulants was associated with lower risk of all studied outcomes.

Introduction Immunomodulatory drugs used to treat multiple myeloma carry an increased risk of venous thromboembolic (VTE) disease. Previously published guidelines outline consensus opinion on how to mitigate this risk. Methods We collected baseline data to analyze how these strategies are utilized at our single institution and sought to improve the rates of anticoagulation for high-risk patients. This was done through a quality improvement project that added pharmacy/haematology oversight to the VTE risk assessment. Results Thirty-nine patients newly started on IMiDs were assessed for VTE risk. This information was passed on to the myeloma provider for consideration. Twenty-two patients were classified as high risk for VTE. Of the high-risk patients, 14 (64%) were placed on an anticoagulant for thromboprophylaxis. Eleven (79%) of the 14 used direct oral anticoagulants (DOACs). Eight high-risk patients did not receive an anticoagulant for thromboprophylaxis; 4 of these developed VTE. No patients on anticoagulation developed a VTE. This strategy had rare minor bleeding complications. Conclusion This quality action verifies guideline-based thromboprophylaxis in multiple myeloma and supports the benefit of pharmacy oversight in improving VTE rates. The use of DOACs in myeloma should be further explored.

Abstract Background Retreatment tuberculosis (TB) disease is common in high-prevalence settings. The risk of repeated episodes of recurrent TB is unknown. We calculated the rate of recurrent TB per subsequent episode by matching individual treatment episodes over a period of 13 years. Methods All recorded TB episodes in Cape Town between 2003 and 2016 were matched by probabilistic linkage of personal identifiers. Among individuals with a first episode notified in Cape Town and who completed their prior treatment successfully we estimated the recurrence rate stratified by subsequent episode and HIV status. We adjusted person-time to background mortality by age, sex, and HIV status. Results A total of 292 915 TB episodes among 263 848 individuals were included. The rate of recurrent TB was 16.4 per 1000 person-years (95% CI, 16.2–16.6), and increased per subsequent episode (8.4-fold increase, from 14.6 to 122.7 per 1000 from episode 2 to 6, respectively). These increases were similar stratified by HIV status. Rates among HIV positives were higher than among HIV negatives for episodes 2 and 3 (2- and 1.5-fold higher, respectively), and the same thereafter. Conclusions TB recurrence rates were high and increased per subsequent episode, independent of HIV status. This suggests that HIV infection is insufficient to explain the high burden of recurrence; it is more likely due to a high annual risk of infection combined with an increased risk of infection or progression to disease associated with a previous TB episode. The very high recurrence rates would justify increased TB surveillance of patients with &gt;1 episode.

Introduction: Medicines don’t work in those who don’t take them. Although novel oral anticoagulants (NOACs) are more convenient than warfarin due to fewer drug-drug interactions and less need for laboratory monitoring, their considerable costs and lack of regular interactions with the healthcare system may also contribute to poor adherence. Little is known about the persistence and adherence in the era of NOACs, nor how such behaviors are associated with the risk of ischemic stroke and transient ischemic attack (TIA) among patients of varying baseline risk. Methods: We conducted a retrospective analysis using a large U.S. commercial insurance database, and identified 61,646 patients with atrial fibrillation who initiated one of OACs (warfarin, dabigatran, rivaroxaban and apixaban) between October 2010 and September 2014. We defined discontinuation as being off OACs for at least 3 months and adherence as the proportion of days covered of at least 80%. Cox proportional hazard models was used to examine whether the time that patients were off OACs, including both the gaps between medication fills and the time of discontinuation, increased the risk of ischemic stroke and TIA. Results: Approximately 1 in 3 patients discontinued OACs within one year after initiation and 1 in 10 switched to another OAC. The estimated likelihood of adherence was 0.77 during the time when patients were on their first-line medications. Apixaban had the highest continuation rate (65% at 1 year), while rivaroxaban had the best adherence (predicted probability of adherence 0.83). The event rate of stroke was 1.6 per 100 person years. Patients with high baseline risk (CHA2DS2-VASc ≥2) were more likely to have a stroke when they were off OACs for 1-3 months (HR=1.47, p<0.01), 3-6 months (HR=1.78, p<0.001) and ≥6 months (HR=2.16, p<0.001), compared to off OACs for less than a week. No significant effect was found among low-risk patients (CHA2DS2-VASc 0 or 1). Switching to another OAC was related to 22% increased risk of stroke (p=0.05). Conclusions: Despite their greater convenience relative to warfarin, discontinuation and nonadherence to NOACs is high. Lack of persistence and adherence was associated with increased risk of ischemic stroke and TIA among patients with elevated baseline risk.

Background:Atrial fibrillation (AF) is associated with an increased risk of cardioembolic stroke. The risk of cardioembolism is not adequately reduced with the administration of oral anticoagulants, since a number of patients continue to experience thromboembolic events despite receiving treatment. Therefore, identification of a circulating biomarker to identify these high-risk patients would be clinically beneficial.Objective:In the present article, we aim to review the available data regarding use of biomarkers to predict cardioembolic stroke in patients with AF.Methods:We performed a thorough search of the literature in order to analyze the biomarkers identified thus far and critically evaluate their clinical significance.Results:A number of biomarkers have been proposed to predict cardioembolic stroke in patients with AF. Some of them are already used in the clinical practice, such as d-dimers, troponins and brain natriuretic peptide. Novel biomarkers, such as the inflammatory growth differentiation factor-15, appear to be promising, while the role of micro-RNAs and genetics appear to be useful as well. Even though these biomarkers are associated with an increased risk for thromboembolism, they cannot accurately predict future events. In light of this, the use of a scoring system, that would incorporate both circulating biomarkers and clinical factors, might be more useful.Conclusions:Recent research has disclosed several biomarkers as potential predictors of cardioembolic stroke in patients with AF. However, further research is required to establish a multifactorial scoring system that will identify patients at high-risk of thromboembolism, who would benefit from more intensive treatment and monitoring.

SummaryInherited thrombophilic states are associated with an increased risk for deep vein thrombosis (DVT), but whether they are also risk factors for superficial vein thrombosis (SVT) is uncertain. We assessed the risk conferred by inherited thrombophilic states in patients with a first episode of SVT in whom the coexistence of DVT had been ruled out by ultrasonography. Sixty-three patients with SVT, after exclusion of patients with varicose veins, malignant or autoimmune disease, and 537 healthy individuals were investigated. The G1691A mutation in the factor V gene, the G20210A mutation in the prothrombin gene, and deficiencies of the naturally occurring inhibitors of coagulation (antithrombin, protein C, protein S) were searched. The prevalence of each thrombophilic state was higher in patients than in controls. The odds ratios for SVT were 6.1 (95% confidence interval [CI], 2.6 to 14.2) in patients with the G1691A factor V mutation, 4.3 (95% CI, 1.5 to 12.6) in those with the G20210A prothrombin mutation, and 12.9 (95% CI, 3.6 to 46.2) in those with deficiencies of the naturally occurring inhibitors of coagulation taken together. Risks did not substantially change when the analysis was restricted to 43 patients who had SVT as their only thrombotic manifestation, being 4.3 (95% CI, 1.5 to 12.3) in patients with factor V mutation, and 3.6 (95% CI, 1.0 to 13.1) in those with the prothrombin mutation. Among the circumstantial risk factors investigated (surgery, trauma, prolonged immobilization, oral contraceptives and pregnancy or puerperium), pregnancy or puerperium was the most frequently associated with SVT, being present in 38% of women. Our findings indicate that inherited thrombophilic states are associated with an increased risk for SVT. Hence, a laboratory search of these alterations is recommended in patients with SVT, because it allows the identification of patients at high risk of DVT in whom antithrombotic prophylaxis is particularly warranted.

Abstract Pulmonary embolism (PE) is the most frequently missed diagnosis in the urgent clinical department with serious consequences. Patients with unprovoked PE have increased risk of recurrent PE. Approximately 5 to 8% of PE patients have inherited thrombophilias. A solated homocystinemia is a rare cause of unprovoked acute pulmonary embolism. Timely diagnosis and proper treatment can prevent complications, costs and mortality and provide patient better quality of life. We are presenting a 42-year-old woman was admitted to our emergency department with the first episode of severe dyspnea and chest pain. She had no history of previous cardiovascular or respiratory disease and no history of previous pulmonary embolism (PE) or deep vein thrombosis (DVT). Urgent echocardiography showed indirect signs of pulmonary embolism which was confirmed by the pulmonary artery CT angiography performed one day after the patient’s admission. After two days of heparin infusion, she developed a hemodynamic instability with cardiogenic shock and was treated successfully with fibrinolysis. After the clinical stabilization, she was put on the rivaroxaban therapy, which was recommended for additional six months. The thrombophilia profile was done two weeks after stopping the therapy with rivaroxaban. The thrombophilia panel came back positive for high levels of homocysteine (67 μmol/L), with other thrombophilia results within normal limits. The patient was stable during the follow-up period. Pulmonary embolism should be always suspected in younger patients with acute severe dyspnea even without provocable risk factors. High suspicion level and fast diagnosis are lifesaving. In younger patients presented with unprovoked pulmonary embolism, clinicians should consider inherited prothrombotic factors and homocystinemia as a potential cause. Rescue fibrinolysis is a lifesaving therapy in hemodynamic worsening in intermediate high-risk PE patients. A longer anticoagulation therapy should be considered in these cases with novel oral anticoagulants that are recommended as safer and superior therapy.
