Background/Aim: The frequency of detecting cancer-associated venous thromboembolism (CAT) during chemotherapy is increasing. It is not desirable to discontinue chemotherapy for CAT. In this study, we investigated the feasibility of simultaneous progression of anticoagulant and anticancer therapy, focusing on drug interactions. Patients and Methods: We retrospectively evaluated patients with gastroenterological CAT from February 2017 to December 2020 at the Gifu University Hospital. When both chemotherapy and CAT treatments using edoxaban were performed in parallel and the thrombus disappeared, patients were defined as being Keep-ACT2 (keeping anticancer therapy and anticoagulant therapy) successful. The effect and safety of treatment strategy focusing on cytochrome P450 (CYP) metabolism using edoxaban were evaluated. Results: A total of 114 patients with CAT during chemotherapy were treated with edoxaban. Keep-ACT2 was successful in 101 (88.6%) cases. Clinically relevant non-major bleeding was observed in 5 cases (4.4%). All 114 patients were using some drug affected by CYP metabolism, and the median number of affected cases was 5. Conclusion: Combined use of edoxaban for CAT may lead to sustainable therapy for gastroenterological cancer patients who are administered several drugs.

Risk Of Bleeding

SummaryExisting clinical scores do not perform well in predicting bleeding in elderly patients with acute venous thromboembolism (VTE). We sought to derive an easy-to-use clinical score to help physicians identify elderly patients with VTE who are at high-risk of bleeding during extended anticoagulation (>3 months). Our derivation sample included 743 patients aged ≥65 years with VTE who were enrolled in a prospective multicenter cohort study. All patients received extended anticoagulation with vitamin K antagonists. We derived our score using competing risk regression, with the time to a first major bleeding up to 36 months of extended anticoagulation as the outcome, and 17 candidate variables as predictors. We used bootstrapping methods for internal validation. Sixty-six (9%) patients suffered major bleeding. The clinical score is based on seven clinical factors (previous bleeding, active cancer, low physical activity, anemia, thrombocytopenia, antiplatelet drugs/NSAIDs, and poor INR control). Overall, 48% of patients were classified as low-risk, 37% as moderate-risk, and 15% as high-risk of bleeding. The rate of major bleeding was 1.4 events in low-risk, 5.0 events in moderate-risk, and 12.2 events per 100 patientyears in high-risk patients. The c-statistic was 0.78 at 3 months and 0.71 at 36 months of extended anticoagulation. Model calibration was excellent (p=0.93). Internal validation showed similar results. This simple clinical score accurately identified elderly patients with VTE who are at high risk of major bleeding and who may not benefit from extended anticoagulation. Further validation of the score is important before its implementation into practice. The study is registered to https://clinicaltrials.gov as NCT00973596.This work was carried out at the Department of General Internal Medicine in the Bern University Hospital, Switzerland.

Background: Several studies suggest an increased incidence of thrombosis in COVID-19 patients. However, evidence on how to prevent and even treat it is scarce. The aim of this study was to compare the cumulative incidence of venous thromboembolism (VTE) of two different methods for lower extremity deep vein thrombosis (LE-DVT) diagnosis: systematic vs. clinically guided complete compression venous ultrasonography (CCUS). We conducted a monocentric, prospective, open-label, non-randomized study. All consecutive patients admitted in three intensive care units (ICUs) of University Hospital of Toulouse for COVID-19 pneumonia were included: one performed systematic screening for LE-DVT, the others did not. The primary outcome was the 21-day cumulative incidence of VTE. The secondary end points were the 21-day cumulative incidences of major bleeding and death.Results: Among the 78 patients included, 27 (34.6%) underwent systematic screening for DVT 7 ± 2 days after ICU admission. Thirty-two patients (41.0%) were diagnosed with VTE, with a 21-day cumulative incidence of 42.3% (95% CI, 31.4–55.2), without difference between screened and non-screened patients (hazard ratio 1.45, 95% CI, 0.72–2.93). In the screened group, the frequency of isolated DVT was higher (25.9 vs. 5.9%, p-value = 0.027), but the frequency of pulmonary embolism was not reduced (25.9 vs. 29.4%, p-value = 0.745). The 21-day cumulative incidences of major bleeding and death were 9.6% (95% CI, 4.7–19.2) and 10.3% (95% CI, 5.0–20.8), respectively, without difference between the two groups.Conclusions: A systematic screening for DVT in patients hospitalized in ICU was not associated with a higher diagnosis of VTE or a reduced diagnosis of PE.

Abstract Funding Acknowledgements Type of funding sources: None. Background- Low molecular weight heparin (LMWH) and direct oral anticoagulants (DOACs) have been proven to be more effective in the management of venous thromboembolism (MVTE). The efficacy and safety of LMWH or DOACs in treatment of recurrent or malignancy induced VTE is not studied in literature. Objective To compare the efficacy and safety of LMWH and  DOACs in the management of malignancy induced  VTE Methods- Electronic databases ( PubMed, Embase, Scopus, Cochrane) were searched from inception to November  28th, 2020. Dichotomous data was extracted for prevention of VTE and risk of major bleeding in patients taking either LMWH or DOACs. Unadjusted odds ratios (OR) were calculated from dichotomous data using Mantel Haenszel (M-H) random-effects with statistical significance to be considered if the confidence interval excludes 1 and p < 0.05.  Results- Three studies with 2607 patients (DOACs n = 1301 ; LMWH n = 1306) were included in analysis. All the study population had active cancer of any kind diagnosed within the past 6 months. Average follow-up period for each trial was 6 months. Patients receiving DOACs have a lower odds of recurrence of MVTE as compared to LMWH( OR 1.56; 95% CI 1.17-2.09; P = 0.003, I2 = 0). There was no significant difference in major bleeding among patients receiving LMWH or DOACs  (OR-0.71, 95%CI 0.46-1.10, P = 0.13, I2 = 22%) (Figure 1). We had no publication bias in our results (Egger’s regression p > 0.05). Conclusion- DOACs are superior to LMWH in prevention of MVTE and have similar major bleeding risk as that of LMWH.

Background: Anticoagulation monitoring practices vary during extracorporeal membrane oxygenation (ECMO). The Extracorporeal Life Support Organization describes that a multimodal approach is needed to overcome assay limitations and minimize complications. Objective: Compare activated clotting time (ACT) versus multimodal approach (activated partial thromboplastin time (aPTT)/anti-factor Xa) for unfractionated heparin (UFH) monitoring in adult ECMO patients. Methods: We conducted a single-center retrospective pre- (ACT) versus post-implementation (multimodal approach) study. The incidence of major bleeding and thrombosis, blood product and antithrombin III (ATIII) administration, and UFH infusion rates were compared. Results: Incidence of major bleeding (69.2% versus 62.2%, p = 0.345) and thrombosis (23% versus 14.9%, p = 0.369) was similar between groups. Median number of ATIII doses was reduced in the multimodal group (1.0 [IQR 0.0-2.0] versus 0.0 [0.0 -1.0], p = 0.007). The median UFH infusion rate was higher in the ACT group, but not significant (16.9 [IQR 9.6-22.4] versus 13 [IQR 9.6-15.4] units/kg/hr, p = 0.063). Fewer UFH infusion rate changes occurred prior to steady state in the multimodal group (0.9 [IQR 0.3 -1.7] versus 0.1 [IQR 0.0-0.2], p < 0.001). Conclusion: The incidence of major bleeding and thrombosis was similar between groups. Our multimodal monitoring protocol standardized UFH infusion administration and reduced ATIII administration.

AbstractAlthough extracorporeal membrane oxygenation (ECMO) is increasingly utilized, only a limited level of experience has been reported in postpartum cardiopulmonary failure. Ten critically ill postpartum patients who received ECMO were included between January 2010 and December 2018 in this retrospective observational study. The main indication for ECMO support was peripartum cardiomyopathy (n = 5), followed by postpartum hemorrhage (n = 2). Nine patients initially received veno-arterial ECMO, and one patient received veno-venous ECMO. Major bleeding occurred in six patients. The median number of units of red blood cells (RBC) transfused during ECMO was 14.5 units (interquartile range 6.8–37.8 units), and most RBC transfusions occurred on the first day of ECMO. The survival-to-discharge rate was 80%. Compared to the survival outcomes in female patients of similar age who received ECMO, the survival outcomes were significantly better in the study population (56% versus 80%, P = 0.0004). Despite the high risk of major bleeding, ECMO for patients with postpartum cardiac or respiratory failure showed excellent survival outcomes. ECMO is feasible in these patients and can be carried out with good outcomes in an experienced centre.

AbstractEfficacy and safety of anticoagulant treatment for venous thromboembolism (VTE) may vary in patients with different cancer sites. We evaluated the rates of VTE recurrence and major bleeding and the relative efficacy and safety of 6-month treatment with oral apixaban or subcutaneous dalteparin in patients with different cancer sites randomized in the Caravaggio study. Primary cancer was located at gastrointestinal sites in 375 patients (32.5%), lung in 200 (17.3%), breast in 155 (13.4%), genitourinary sites in 139 (12%), gynecological sites in 119 (10.3%), and was hematological in 85 patients (7.4%). Rates of VTE recurrence were 10.9% in patients with gynecological, 8.8% with gastrointestinal, 6.5% with genitourinary, and 5.5% with lung cancer with lower rates in the other sites of cancer. Rates of major bleeding were 7.2% in patients with genitourinary and 4.8% with gastrointestinal cancer, with lower rates in patients with other sites of cancer. The observed absolute risk difference in VTE recurrence in favor of apixaban was 11.9% in patients with gynecological, 5.5% with lung, 3.7% with genitourinary cancer, and 0.6% with gastrointestinal cancer. None of the risk differences was statistically significant. The rates of major bleeding in patients treated with apixaban or dalteparin was similar across patients with different cancer sites. In conclusion, recurrences appear to be more common in patients with gastrointestinal and gynecological cancer and major bleedings in patients with genitourinary and gastrointestinal cancer. Oral apixaban is a valid oral alternative to subcutaneous dalteparin for the treatment of a large spectrum of patients with cancer-associated VTE.

Introduction: Patients with cancer are at high risk for recurrent thromboembolic phenomenon. Use of novel oral anticoagulants (NOAC) for treatment of venous thromboembolism (VTE) in such patients is controversial. We conducted this updated meta-analysis to evaluate the pooled efficacy and safety of NOAC in patients with cancer. Methods: We did systematic search of PubMed and Cochrane library databases for randomized controlled trials comparing NOAC with low molecular weight heparin (LMWH) for VTE treatment in cancer patients till April 2020. The efficacy outcomes were recurrent VTE and all-cause mortality rates, and the primary safety outcome was incidence of major bleeding rate. Results: Four randomized controlled studies comparing NOAC with LMWH (1446 patients in NOAC group and 1448 patients in LMWH group) were included in our study. Use of NOAC lead to significant reduction in recurrent VTE rate (odds ratio (OR): 0.55 [0.36-0.84], I 2 = 45 %, p value = 0.006) (Figure 1). However, we did not find any significant difference in rate of major bleeding (OR: 1.30 [0.76-2.23], I 2 = 35%, p value = 0.34) (Figure 2) and all-cause mortality (OR: 1 [0.80 - 1.26], I 2 = 33%, p value = 0.98). Conclusions: This updated meta-analysis showed comparatively lower pooled recurrent VTE rate in patient being treated with NOAC, whereas similar rates of major bleeding and all-cause death. NOAC are more efficacious and has similar safety profile compared with LMWH.

SummaryCancer patients with acute venous thromboembolism (VTE) have an increased incidence of recurrences and bleeding complications while on anticoagulant therapy. Methods RIETE is an ongoing registry of consecutive patients with acute VTE. We tried to identify which cancer patients are at a higher risk for recurrent pulmonary embolism (PE), deep vein thrombosis (DVT) or major bleeding. Up to May 2007, 3, 805 cancer patients had been enrolled in RIETE. During the first three months of follow-up after the acute, index VTE event, 90 (2.4%) patients developed recurrent PE, 100 (2.6%) recurrent DVT, 156 (4.1%) had major bleeding. Forty patients (44%) died of the recurrent PE,46 (29%) of bleeding. On multivariate analysis, patients aged <65 years (odds ratio [OR]: 3.0; 95% confidence interval [CI]: 1.9–4.9), with PE at entry (OR: 1.9; 95% CI: 1.2–3.1), or with <3 months from cancer diagnosis to VTE (OR: 2.0; 95% CI: 1.2–3.2) had an increased incidence of recurrent PE. Those aged <65 years (OR: 1.6; 95% CI: 1.0–2.4) or with <3 months from cancer diagnosis (OR: 2.4; 95% CI: 1.5–3.6) had an increased incidence of recurrent DVT. Finally, patients with immobility (OR: 1.8; 95% CI: 1.2–2.7), metastases (OR: 1.6; 95% CI: 1.1–2.3), recent bleeding (OR: 2.4; 95% CI: 1.1–5.1), or with creatinine clearance <30 ml/ min (OR: 2.2; 95% CI: 1.5–3.4), had an increased incidence of major bleeding. With some variables available at entry we may identify those cancer patients withVTE at a higher risk for recurrences or major bleeding.

Background: Bronchiectasis is a chronic inflammation of the bronchi with recurrent infections and hemoptysis. The MAGELLAN study compared oral rivaroxaban, 10 mg once daily (QD), for 35 ± 4 days with subcutaneous enoxaparin 40 mg QD for 10 ± 4 days followed by placebo for 25 ± 4 days to prevent venous thromboembolism in patients hospitalized with an acute medical illness. MAGELLAN included a subset of patients with bronchiectasis. In a post hoc analysis, we evaluated the incidence and severity of pulmonary bleeding in patients with bronchiectasis who were hospitalized for an acute medical illness. This analysis included MAGELLAN patients diagnosed with bronchiectasis at baseline. Patients were evaluated by treatment group for International Society on Thrombosis and Haemostasis major bleeding, non-major clinically relevant (NMCR) bleeding, and the composite of the 2 (ie, clinically relevant bleeding). Results: Medically ill patients with bronchiectasis were randomized to rivaroxaban (n = 60) or enoxaparin/placebo (n = 61). There were 2 fatal pulmonary bleeds and 1 fatal gastrointestinal bleed in the rivaroxaban arm and no fatal or major bleeding in the enoxaparin/placebo arm. The incidence of major bleeding was 5% in the rivaroxaban arm. One NMCR bleed occurred in the rivaroxaban arm and 2 NMCR bleeds occurred in the enoxaparin/placebo arm. The incidence of clinically relevant bleeding was 6.7% versus 3.3% in the rivaroxaban and enoxaparin/placebo groups, respectively (relative risk = 2.06 [95% confidence interval: 0.351-12.046]). Conclusion: In-patients hospitalized with bronchiectasis and an acute medical illness, clinically relevant bleeding, including fatal pulmonary hemorrhage, occurs more frequently with extended rivaroxaban thromboprophylaxis than with enoxaparin followed by placebo.
