Background The efficacy and safety of the direct oral anticoagulants (DOACs) in fragile patients (age ≥ 75 years and/or creatinine clearance levels ≤ 50 mL/min and/or body weight ≤ 50kg) with venous thromboembolism (VTE) has not been evaluated. Methods We used the RIETE database to compare the rates of the composite of VTE recurrences or major bleeding during anticoagulation in fragile patients with VTE, according to the use of DOACs or standard anticoagulant therapy. Results From January 2013 to April 2018, 24,701 patients were recruited. Of these, 10,054 (41%) were fragile. Initially, 473 fragile patients (4.7%) received DOACs and 8,577 (85%) low-molecular-weight heparin (LMWH). For long-term therapy, 1,298 patients (13%) received DOACs and 5,038 (50%) vitamin K antagonists (VKAs). Overall, 95 patients developed VTE recurrences and 262 had major bleeding. Patients initially receiving DOACs had a lower rate of the composite outcome (hazard ratio [HR]: 0.32; 95% confidence interval [CI]: 0.08–0.88) than those on LMWH. Patients receiving DOACs for long-term therapy had a nonsignificantly lower rate of the composite outcome (HR: 0.70; 95% CI: 0.46–1.03) than those on VKAs. On multivariable analysis, patients initially receiving DOACs had a nonsignificantly lower risk for the composite outcome (HR: 0.36; 95% CI: 0.11–1.15) than those on LMWH, while those receiving DOACs for long-term therapy had a significantly lower risk (HR: 0.61; 95% CI: 0.41–0.92) than those on VKAs. Conclusions Our data suggest that the use of DOACs may be more effective and safe than standard therapy in fragile patients with VTE, a subgroup of patients where the risk for bleeding is particularly high.

SummaryIn patients with venous thromboembolism (VTE), the influence on outcome of using direct oral anticoagulants (DOACs) at non-recommended doses or regimens (once vs twice daily) has not been investigated yet. We used the RIETE (Registro Informatizado Enfermedad TromboEmbólica) registry to compare the outcomes in patients with VTE receiving DOACs according to the recommendations of the product label versus in those receiving non-recommended doses and/or regimens. The major outcomes were the rate of VTE recurrences, major bleeding and death during the course of therapy. As of March 2016, 1635 VTE patients had received DOACs for initial therapy and 1725 for long-term therapy. For initial therapy, 287 of 1591 patients (18 %) on rivaroxaban and 22 of 44 (50 %) on apixaban did not receive the recommended therapy. For long-term therapy, 217 of 1611 patients (14 %) on rivaroxaban, 29 of 81 (36 %) on apixaban and 15 of 33 (46 %) on dabigatran did not receive the recommended therapy. During the course of therapy with DOACs, eight patients developed VTE recurrences, 14 had major bleeding and 13 died. Patients receiving DOACs at non-recommended doses and/or regimens experienced a higher rate of VTE recurrences (adjusted HR: 10.5; 95 %CI: 1.28–85.9) and a similar rate of major bleeding (adjusted HR: 1.04; 95 %CI: 0.36–3.03) or death (adjusted HR: 1.41; 95 %CI: 0.46–4.29) than those receiving the recommended doses and regimens. In our cohort, a non-negligible proportion of VTE patients received non-recommended doses and/or regimens of DOACs. This use may be associated with worse outcomes.

Introduction: The clinical characteristics, treatment strategies and outcome of patients with venous thromboembolism (VTE) may vary from country to country. Materials and methods: The RIETE (Registro Informatizado su la Enfermedad TromboEmbolica) is an ongoing, prospective registry of consecutive patients with acute, objectively confirmed, symptomatic VTE. Our aim was to assess the influence of surgery and immobility for non-surgical reasons on 3-month outcomes of all Italian patients registered in the RIETE. Results: Through July 2008, 21,397 patients with acute VTE were registered in the RIETE. Of these, 896 (4.2%) were Italian, and 360 (40%) presented with pulmonary embolism (PE). Overall, 137 (15%) developed VTE after surgery; 156 (17%) developed VTE after >4 days of immobility, and 603 (67%) developed VTE in the absence of surgery or immobility. Most patients (83%) received initial therapy with low-molecular-weight heparin; 15% received unfractionated heparin. For long-term therapy, 63% of patients received vitamin K antagonists. The incidence of fatal PE during the first 3 months of therapy was 1.5% for patients with postoperative VTE, 7.7% for who developed VTE after immobility, and 1.2% for the remaining patients. The incidence of fatal bleeding among these patients was 1.5%, 1.9% and 0.3%, respectively. Of the 137 patients with postoperative VTE, 61% had received VTE prophylaxis. Of the 156 patients with recent immobility, 24% had received VTE prophylaxis. Conclusions: VTE arising after a period of immobility was associated with the highest rates of fatal PE and fatal bleeding during the first 3 months of therapy. The use of thromboprophylaxis in this population should be improved.

SummaryLong-term therapy with low-molecular-weight heparin (LMWH) is the treatment of choice for cancer patients with venous thromboembolism (VTE). However, the ideal doses of LMWH have not been thoroughly studied. We used the RIETE Registry data to assess the influence of the daily LMWH dosage on outcome during the first three months after VTE. We used propensity score-matching to compare patients who received <150 vs. those receiving ≥150 UI/kg/day LMWH. Up to July 2010, 3,222 cancer patients with VTE received long-term therapy with fixed doses of LMWH. Of these, 1,472 (46%) received <150 IU/kg/day (mean, 112 ± 28), and 1,750 received ≥150 IU/kg/day (mean, 184 ± 32). Results of the propensity score matching involved 1269 matched pairs. During follow-up, the incidence of pulmonary embolism (PE) recurrences was similar (1.2% vs. 1.9%), but patients receiving <150 IU/kg/day LMWH had a lower incidence of fatal PE than those treated with ≥150 IU/kg/day (0.2% vs. 1.0%; p=0.004). Multivariate analysis confirmed that patients receiving <150 IU/kg/day LMWH had a lower risk for fatal PE (odds ratio [OR]: 0.2; 95% confidence interval [CI]: 0.06–0.8) and for major bleeding (OR: 0.6; 95% CI: 0.3–1.0) than those treated with ≥150 IU/kg/day. In real life, one in every two cancer patients with VTE received lower doses of LMWH than those used in randomised trials, with large variations from patient to patient. Unexpectedly, patients treated with <150 IU/kg/day LMWH had fewer fatal PE cases and fewer major bleeding events than those receiving ≥150 IU/kg/day LMWH. This finding, however, should be validated in prospective clinical trials.

SummaryProblems with unfractionated heparin as an antithrombotic have led to the development of new therapeutic agents. Of these, low molecular weight heparin shows great promise and has led to out-patient therapy of DVT/PE in selected patients. Oral anticoagulants remain the choice for long-term therapy. More cost-effective ways to give oral anticoagulants are needed.
