COPD linked to higher in-hospital death rates in patients with PAD
A growing body of evidence suggests that, along with other vascular beds, smoking and chronic obstructive pulmonary disease (COPD) affect the arteries of the lower limbs in terms of the development of peripheral arterial disease (PAD), reported Karsten Keller, MD, of the Johannes Gutenberg-University Mainz (Germany) and his colleagues.
This provided the rationale for their large database analysis of inpatients with concomitant COPD and PAD. They found that the additional presence of COPD was associated with increased in-hospital mortality in patients with PAD.
“Our data suggest that COPD increased the mortality of PAD patients by the factor 1.2-fold,” they wrote in Respiratory Medicine. “Unexpectedly, this increase was not driven by [myocardial infarction] as the life-threatening acute presentation of [coronary artery disease], but rather related to an increased risk for [pulmonary embolism] and a higher coprevalence of cancer.”
Dr. Keller and his colleagues inspected the German inpatient national database based on ICD codes. They identified 5,611,827 adult inpatients (64.8% men) diagnosed with PAD between January 2005 and December 2015, and of those, 13.6% also were coded for COPD. Overall, 277,894 PAD patients (5.0%) died in the hospital, Dr. Keller and his colleagues wrote.
The all-cause, in-hospital mortality was significantly higher in PAD patients with COPD, compared with those without COPD (6.5% vs. 4.7%, respectively; P less than .001), and cardiovascular events comprising pulmonary embolism (PE), deep vein thrombosis (DVT), and myocardial infarction (MI) occurred more often in coprevalence with PAD and COPD than in PAD without COPD.
In PAD patients, COPD was an independent predictor of in-hospital death (odds ratio, 1.16; 95% confidence interval, 1.15-1.17; P less than .001) as well as an independent predictor for PE (OR, 1.44; 95% CI, 1.40-1.49; P less than .001).
Overall, PAD patients with COPD were of similar age as (73 years), but stayed slightly longer in the hospital than (9 vs. 8 days), those without COPD. PAD patients without COPD revealed more often cardiovascular risk factors like essential arterial hypertension and diabetes, but the prevalence of cardiovascular diseases such as coronary artery disease and heart failure were more often found in PAD patients with COPD. In addition, cancer and renal insufficiency also were more common in PAD patients with COPD, according to the authors.
“Remarkably, PAD patients with COPD showed more frequently lower PAD stages than those without COPD. Especially, PAD stage IV was more prevalent in PAD patients without COPD (19.6% vs. 13.8%; P less than 0.001),” the authors stated. In addition, amputations were more often performed in PAD patients without COPD.
Dr. Keller and his colleagues had the following conclusions regarding the clinical implications of their study: “I) PAD patients with long-standing tobacco use might benefit from COPD screening and treatment. II) PAD patients with additional COPD should be monitored more intensively, and the treatment for COPD should be optimized. III) COPD increases the risk for PE, and it is critical not to overlook this life-threatening disease. IV) MI and PE are important causes of in-hospital death in PAD patients with and without COPD.”
The German Federal Ministry of Education and Research funded the study, and the authors reported having no conflicts.

ATTRACT trial shouldn’t detract from pharmacomechanical thrombolysis
CHICAGO – A closer look at the landmark ATTRACT trial of pharmacomechanical catheter-directed thrombolysis for acute deep vein thrombosis (DVT) shows multiple benefits for the intervention versus standard anticoagulation alone in the subset of participants with iliofemoral DVT, Kush R. Desai, MD, said at a symposium on vascular surgery sponsored by Northwestern University.
ATTRACT, a National Institutes of Health–sponsored, phase 3, multicenter, open-label, assessor-blinded study, was the first-ever randomized trial of pharmacomechanical catheter-directed thrombolysis (PCDT) for acute DVT.
The results caused a major stir because, despite a sound therapeutic rationale for the procedure, the incidence of chronic postthrombotic syndrome (PTS) at 24 months of follow-up was 47% in the PCDT plus anticoagulation group and 48% in controls on anticoagulation alone (N Engl J Med. 2017 Dec 7;377[23]:2240-52). Since then, that overall negative trial has been one of the hottest topics in DVT.
“This is the first thing your educated patients who come to the emergency department with DVT will ask about. It’s the first thing they’ll see when they go online and type in ‘thrombolysis DVT,’ ” noted Dr. Desai, an interventional radiologist at Northwestern University, Chicago.
But the trial has several major flaws, he cautioned. And contrary to popular opinion, ATTRACT is not the death knell for PCDT. Far from it.
“I don’t think the story stops with ATTRACT. This isn’t the end for PCDT in patients with iliofemoral DVT,” he asserted.
That’s in part because 301 of the 692 participants in ATTRACT had DVT of the femoropopliteal segment. That’s a population in which Dr. Desai and other interventionalists wouldn’t have anticipated seeing a benefit for PCDT, because their risk of PTS is so low.
“We know through historical data that patients with iliofemoral DVT are much more likely to develop PTS and to have recurrent DVT, so this is probably one of the major shortcomings of the trial,” he explained. “It’s through no fault of the trial investigators, because the study was planned years ago when we just didn’t know as much about PTS as we do now.
“The way I look at it is, I don’t practice in the way that ATTRACT was designed,” Dr. Desai said. “I don’t typically lyse or get referrals for lysis or thrombectomy in patients who have isolated femoropopliteal DVT. It has to involve at least the common femoral vein and frequently goes up to the iliac vein.”
The ATTRACT investigators’ recent subanalysis of the 391 participants with iliofemoral DVT showed that, although there was no difference between the two study arms in the occurrence of PTS through the first 24 months of follow-up, PCDT led to a 35% reduction in the incidence of moderate or severe PTS – by a margin of 18% versus 28% in controls.
Patients in the PCDT arm also experienced significantly greater improvement in venous disease-specific quality of life through 24 months, and a greater reduction in leg pain and swelling at 10 and 30 days (Circulation. 2018 Dec 4. doi: 10.1161/CIRCULATIONAHA.118.037425).
And moderate to severe PTS is a key outcome, Dr. Desai continued. Multiple studies have shown that patients with PTS have a worse quality of life than those with chronic lung disease, arthritis, or diabetes. Moreover, the 5%-10% of patients with symptomatic DVT who develop the most-severe form of PTS – characterized by severe pain, chronic ulcerations, stasis dermatitis, venous claudication, and intractable edema – have a quality of life comparable with patients with cancer or heart failure.
The 1.5% incidence of major bleeding within 10 days in the PCDT group was 200% higher than in controls, but none of it was life threatening.
“This is reassuring: Nobody had intracranial hemorrhage; nobody had a GUSTO 5 bleed,” Dr. Desai said.
Another limitation of the ATTRACT trial is that all but one of the devices utilized for PCDT were used off label. They weren’t designed for venous application. Several on-label rheolytic, rotational thrombectomy, or clot aspiration devices have been approved since enrollment in ATTRACT was closed. Future randomized trials will utilize on-label devices in patients with acute iliofemoral DVT to clarify the role of PCDT.
It’s noteworthy that nearly half of ATTRACT participants developed PTS within 24 months of their DVT despite being on optimal anticoagulation. It’s a finding that underscores the need for improved therapies. That was the impetus for development of first-generation catheter-directed thrombolysis utilizing a percutaneously inserted catheter to infuse a fibrinolytic drug directly to the thrombus to dissolve it rapidly.
But that form of catheter-directed thrombolysis has major disadvantages, Dr. Desai explained: It’s a multiday procedure requiring ICU-level care and prolonged exposure to powerful lytic agents.
“This is where things have changed with PCDT,” he said. “We can now, with on-label devices, accelerate the thrombolysis time, reduce lytic exposure, and I think also reduce the bleeding risk, although that hasn’t been shown in a trial yet. PCDT also reduces the necessity for ICU-level care and prolonged hospitalization.”
Dr. Desai no longer performs multiday lytic procedures. “In fact, with the introduction of the newer on-label devices, I haven’t done a multiday unilateral limb lytic procedure in a couple years. I think we’ve gotten to the point where we don’t need to do that anymore.”
Indeed, PCDT makes recanalization possible as a single-day, single-session procedure.
Dr. Desai views the recent ATTRACT subanalysis as hypothesis generating.
“Should PCDT be the first-line treatment in all proximal DVT patients? No it should not – and that’s not what I would have advocated even before ATTRACT came out,” he explained. “It’s sort of a salvage procedure for patients with iliofemoral DVT and moderate to severe symptoms. And there are a significant number of such patients.”
Current understanding of the pathophysiology of PTS is that a nondissolved thrombus at the valve leaflets becomes inflammatory, with resultant valvular dysfunction leading to venous reflux and venous hypertension. PCDT is consistent with the open-vein hypothesis, which posits that, by eliminating thrombus much faster than achievable via anticoagulation, valve integrity is maintained and PTS is prevented.
Dr. Desai reported receiving consulting fees from AngioDynamics, Boston Scientific, Cook Medical, and Spectranetics.

EXPERT ANALYSIS FROM THE NORTHWESTERN VASCULAR SYMPOSIUM
Phase 3 data support apixaban for cancer-associated VTE
SAN DIEGO –
according to the Phase 3 ADAM VTE trial.The rates of major bleeding and clinically relevant nonmajor bleeding in patients who received apixaban were similar to those in patients who received dalteparin. However, the rate of VTE recurrence was significantly lower with apixaban than it was with dalteparin.
“[A]pixaban was associated with very low bleeding rates and venous thrombosis recurrence rates compared to dalteparin,” said Robert D. McBane II, MD, of the Mayo Clinic in Rochester, Minn., at the annual meeting of the American Society of Hematology.
The trial included 300 adults (aged 18 years and older) with active cancer and acute VTE who were randomized to receive apixaban (n = 150) or dalteparin (n = 150). The dose and schedule for oral apixaban was 10 mg twice daily for 7 days followed by 5 mg twice daily for 6 months. Dalteparin was given subcutaneously at 200 IU/kg per day for 1 month followed by 150 IU/kg daily for 6 months. Among the patients in the study, 145 patients in the apixaban arm and 142 in the dalteparin arm ultimately received their assigned treatment.
Every month, patients completed an anticoagulation satisfaction survey and bruise survey (a modification of the Duke Anticoagulation Satisfaction Scale). They also underwent lab testing (complete blood count, liver and renal function testing) and were assessed for outcomes, medication reconciliation, drug compliance, and ECOG status on a monthly basis.
Patient characteristics
Baseline characteristics were similar between the treatment arms. The mean age was 64 years in both arms, and roughly half of patients in both arms were female. Hematologic malignancies were present in 9% of patients in the apixaban arm and 11% in the dalteparin arm. Others included lung, colorectal,
pancreatic/hepatobiliary, gynecologic, breast, genitourinary, upper gastrointestinal, and brain cancers.
Of patients in the study, 65% of those in the apixaban arm and 66% in the dalteparin arm had distant metastasis, and 74% of patients in both arms were receiving chemotherapy while on study.
Patients had the following qualifying thrombotic events:
- Any pulmonary embolism (PE) – 55% of patients in the apixaban arm and 51% in the dalteparin arm
- Any deep vein thrombosis (DVT) – 48% and 47%, respectively
- PE only – 44% and 39%, respectively
- PE with DVT – 12% in both arms
- DVT only – 37% and 35%, respectively
- Lower extremity DVT – 31% and 34%, respectively
- Upper extremity DVT – 17% and 14%, respectively
- Cerebral venous thrombosis (VT) – 1% and 0%, respectively
- Splanchnic VT – 8% and 18%, respectively.
Bleeding, thrombosis, and death
The study’s primary endpoint was major bleeding, which did not occur in any of the apixaban-treated patients. However, major bleeding did occur in two (1.4%) patients in the dalteparin arm (P = .14).
A secondary endpoint was major bleeding plus clinically relevant nonmajor bleeding. This occurred in nine (6.2%) patients in the apixaban arm and nine (6.3%) in the dalteparin arm (P = .88).
The researchers also assessed VTE recurrence. One patient in the apixaban arm (0.7%) and nine in the dalteparin arm (6.3%) had VTE recurrence (P = .03).
The patient in the apixaban arm experienced cerebral VT, and the patients with recurrence in the dalteparin arm had leg (n = 4) or arm (n = 2) VTE, PE (n = 1), or splanchnic VT (n = 2).
One patient in each arm (0.7%) had arterial thrombosis.
There was no significant difference in cumulative mortality between the treatment arms (hazard ratio, 1.40; P = .3078).
Satisfaction and discontinuation
Overall, apixaban fared better than dalteparin in the monthly patient satisfaction surveys. At various time points, apixaban-treated patients were significantly less likely to be concerned about excessive bruising, find anticoagulant treatment a burden or difficult to carry out, or say anticoagulant treatment added stress to their lives, negatively impacted their quality of life, or caused them “a great deal” of worry, irritation, or frustration.
However, apixaban-treated patients were less likely than dalteparin recipients to have confidence that their drug protected them from VTE recurrence, while the apixaban recipients were more likely than the dalteparin group to report overall satisfaction with their treatment.
In addition, premature treatment discontinuation was more common in the dalteparin group than in the apixaban group – 15% and 4%, respectively (P = .0012).
“Apixaban was well tolerated with superior patient safety satisfaction, as well as significantly fewer study drug discontinuations compared to dalteparin,” Dr. McBane said. “I believe that these data support the use of apixaban for the acute treatment of cancer-associated venous thromboembolism.”
This study was funded by BMS/Pfizer Alliance. Dr. McBane declared no other conflicts of interest.

SAN DIEGO –
according to the Phase 3 ADAM VTE trial.The rates of major bleeding and clinically relevant nonmajor bleeding in patients who received apixaban were similar to those in patients who received dalteparin. However, the rate of VTE recurrence was significantly lower with apixaban than it was with dalteparin.
“[A]pixaban was associated with very low bleeding rates and venous thrombosis recurrence rates compared to dalteparin,” said Robert D. McBane II, MD, of the Mayo Clinic in Rochester, Minn., at the annual meeting of the American Society of Hematology.
The trial included 300 adults (aged 18 years and older) with active cancer and acute VTE who were randomized to receive apixaban (n = 150) or dalteparin (n = 150). The dose and schedule for oral apixaban was 10 mg twice daily for 7 days followed by 5 mg twice daily for 6 months. Dalteparin was given subcutaneously at 200 IU/kg per day for 1 month followed by 150 IU/kg daily for 6 months. Among the patients in the study, 145 patients in the apixaban arm and 142 in the dalteparin arm ultimately received their assigned treatment.
Every month, patients completed an anticoagulation satisfaction survey and bruise survey (a modification of the Duke Anticoagulation Satisfaction Scale). They also underwent lab testing (complete blood count, liver and renal function testing) and were assessed for outcomes, medication reconciliation, drug compliance, and ECOG status on a monthly basis.
Patient characteristics
Baseline characteristics were similar between the treatment arms. The mean age was 64 years in both arms, and roughly half of patients in both arms were female. Hematologic malignancies were present in 9% of patients in the apixaban arm and 11% in the dalteparin arm. Others included lung, colorectal,
pancreatic/hepatobiliary, gynecologic, breast, genitourinary, upper gastrointestinal, and brain cancers.
Of patients in the study, 65% of those in the apixaban arm and 66% in the dalteparin arm had distant metastasis, and 74% of patients in both arms were receiving chemotherapy while on study.
Patients had the following qualifying thrombotic events:
- Any pulmonary embolism (PE) – 55% of patients in the apixaban arm and 51% in the dalteparin arm
- Any deep vein thrombosis (DVT) – 48% and 47%, respectively
- PE only – 44% and 39%, respectively
- PE with DVT – 12% in both arms
- DVT only – 37% and 35%, respectively
- Lower extremity DVT – 31% and 34%, respectively
- Upper extremity DVT – 17% and 14%, respectively
- Cerebral venous thrombosis (VT) – 1% and 0%, respectively
- Splanchnic VT – 8% and 18%, respectively.
Bleeding, thrombosis, and death
The study’s primary endpoint was major bleeding, which did not occur in any of the apixaban-treated patients. However, major bleeding did occur in two (1.4%) patients in the dalteparin arm (P = .14).
A secondary endpoint was major bleeding plus clinically relevant nonmajor bleeding. This occurred in nine (6.2%) patients in the apixaban arm and nine (6.3%) in the dalteparin arm (P = .88).

Large cohort study IDs prognostic factors in thromboangiitis obliterans
CHICAGO – Nonwhite ethnicity and limb infection at diagnosis predict vascular events in patients with thromboangiitis obliterans (TAO), and the latter also predicts amputation, which occurs within 10 years of diagnosis in nearly a third of patients, according to findings from a large retrospective French cohort study.
After a mean follow-up of 5.7 years, 58.9% of 224 patients with TAO – also known as Buerger’s disease – experienced a vascular event, 21.4% experienced at least one amputation, and 1.3% died, Alexandre Le Joncour, MD, reported at the annual meeting of the American College of Rheumatology.
The 5- and 15-year vascular event-free survival rates were 45% and 28%, respectively, and the 10- and 15-year amputation-free survival rates were 74%, and 66%, respectively, said Dr. Le Joncour of Sorbonne University, Paris.
Of note, no significant difference was seen in the vascular event-free survival rates based on tobacco use levels (more than 22 pack-years vs. 22 or fewer pack-years; HR, 1.2), he said.
Patient characteristics and clinical factors found to independently predict vascular events included nonwhite ethnicity (hazard ratio, 2.35; P = .005) and limb infection at diagnosis (HR, 3.29; P = .045). Limb infection at diagnosis also independently predicted amputation (HR, 12.1; P less than .001), he said.
“But there was no significant [association with amputation] in patients who had claudication, critical ischemia, or ischemic ulcers/necrosis,” he noted, adding that a comparison of white and nonwhite patients showed that the groups were similar with respect to epidemiologic and cardiovascular factors, clinical symptom distribution, and rates of addiction to tobacco, alcohol, and illicit drugs.
It was also clear that patients who quit using tobacco had a significantly lower risk of amputation than did those who continued using tobacco (P = .001), he said, explaining that 43 of the 48 patients who experienced amputation were current smokers, and 5 were ex-smokers at the time of amputation.
Dr. Le Joncour and his colleagues included TAO patients diagnosed between 1967 and 2016 at a median age of 36 years at the time of first symptoms, with a median of 12 months from symptom onset until diagnosis. About 76% were men, and about 83% were white. Patients with diabetes, atherosclerosis, arterial emboli, connective tissue disease, and/or thrombophilia were excluded.
Vascular events in this study were defined as “an acute worsening of the disease course requiring treatment modifications,” and included critical ischemia (35% of cases), ulcers/necrosis (33%), claudication worsening (16%), deep vein thrombosis (3%), superficial phlebitis (7%), limb infection (4%), and “other” events (2%).
Major amputation was defined as “an amputation involving the tibio-tarsian articulation for lower limbs and the metacarpophalangeal articulation for upper limbs,” he explained.
The median time to amputation was 4 years, and patients who experienced amputation had a median age of 39 years. Half of the 48 patients who experienced amputation had one amputation, nearly a third had two amputations, and 19% had three amputations. About two-thirds had minor amputations and a third had major amputations.
The findings provide important prognostic information regarding TAO, Dr. Le Joncour said, noting that long-term data on outcomes in TAO patients have been lacking.
“We found specific characteristics that identified those at highest risk for subsequent vascular complications, and these factors are not only important predictors of vascular complications or relapse, but may also serve to adjust more aggressive management and close follow-up of these patients,” he concluded.
Dr. Le Joncour reported having no disclosures.

ASH releases new VTE guidelines
The new guidelines, released on Nov. 27, contain more than 150 individual recommendations, including sections devoted to managing venous thromboembolism (VTE) during pregnancy and in pediatric patients. Guideline highlights cited by some of the writing-panel participants included a high reliance on low-molecular-weight heparin (LMWH) agents as the preferred treatment for many patients, reliance on the D-dimer test to rule out VTE in patients with a low pretest probability of disease, and reliance on the 4Ts score to identify patients with heparin-induced thrombocytopenia.
The guidelines took more than 3 years to develop, an effort that began in 2015.
An updated set of VTE guidelines were needed because clinicians now have a “greater understanding of risk factors” for VTE as well as having “more options available for treating VTE, including new medications,” Adam C. Cuker, MD, cochair of the guideline-writing group and a hematologist and thrombosis specialist at the University of Pennsylvania, Philadelphia, said during a webcast to unveil the new guidelines.
Prevention
For preventing VTE in hospitalized medical patients the guidelines recommended initial assessment of the patient’s risk for both VTE and bleeding. Patients with a high bleeding risk who need VTE prevention should preferentially receive mechanical prophylaxis, either compression stockings or pneumatic sleeves. But in patients with a high VTE risk and an “acceptable” bleeding risk, prophylaxis with an anticoagulant is preferred over mechanical measures, said Mary Cushman, MD, professor and medical director of the thrombosis and hemostasis program at the University of Vermont, Burlington.
For prevention of VTE in medical inpatients, LMWH is preferred over unfractionated heparin because of its once-daily dosing and fewer complications, said Dr. Cushman, a member of the writing group. The panel also endorsed LMWH over a direct-acting oral anticoagulant, both during hospitalization and following discharge. The guidelines for prevention in medical patients explicitly “recommended against” using a direct-acting oral anticoagulant “over other treatments” both for hospitalized medical patients and after discharge, and the guidelines further recommend against extended prophylaxis after discharge with any other anticoagulant.
Another important takeaway from the prevention section was a statement that combining both mechanical and medical prophylaxis was not needed for medical inpatients. And once patients are discharged, if they take a long air trip they have no need for compression stockings or aspirin if their risk for thrombosis is not elevated. People with a “substantially increased” thrombosis risk “may benefit” from compression stockings or treatment with LMWH, Dr. Cushman said.
Diagnosis
For diagnosis, Wendy Lim, MD, highlighted the need for first categorizing patients as having a low or high probability for VTE, a judgment that can aid the accuracy of the diagnosis and helps avoid unnecessary testing.
For patients with low pretest probability, the guidelines recommended the D-dimer test as the best first step. Further testing isn’t needed when the D-dimer is negative, noted Dr. Lim, a hematologist and professor at McMaster University, Hamilton, Ont.
The guidelines also recommended using ventilation-perfusion scintigraphy (V/Q scan) for imaging a pulmonary embolism over a CT scan, which uses more radiation. But V/Q scans are not ideal for assessing older patients or patients with lung disease, Dr. Lim cautioned.
Management
Management of VTE should occur, when feasible, through a specialized anticoagulation management service center, which can provide care that is best suited to the complexities of anticoagulation therapy. But it’s a level of care that many U.S. patients don’t currently receive and hence is an area ripe for growth, said Daniel M. Witt, PharmD, professor and vice-chair of pharmacotherapy at the University of Utah, Salt Lake City.
The guidelines recommended against bridging therapy with LMWH for most patients who need to stop warfarin when undergoing an invasive procedure. The guidelines also called for “thoughtful” use of anticoagulant reversal agents and advised that patients who survive a major bleed while on anticoagulation should often resume the anticoagulant once they are stabilized.
For patients who develop heparin-induced thrombocytopenia, the 4Ts score is the best way to make a more accurate diagnosis and boost the prospects for recovery, said Dr. Cuker (Blood. 2012 Nov 15;120[20]:4160-7). The guidelines cite several agents now available to treat this common complication, which affects about 1% of the 12 million Americans treated with heparin annually: argatroban, bivalirudin, danaparoid, fondaparinux, apixaban, dabigatran, edoxaban, and rivaroxaban.
ASH has a VTE website with links to detailed information for each of the guideline subcategories: prophylaxis in medical patients, diagnosis, therapy, heparin-induced thrombocytopenia, VTE in pregnancy, and VTE in children. The website indicates that additional guidelines will soon be released on managing VTE in patients with cancer, in patients with thrombophilia, and for prophylaxis in surgical patients, as well as further information on treatment. A spokesperson for ASH said that these additional documents will post sometime in 2019.
At the time of the release, the guidelines panel published six articles in the journal Blood Advances that detailed the guidelines and their documentation.
The articles include prophylaxis of medical patients (Blood Advances. 2018 Nov 27;2[22]:3198-225), diagnosis (Blood Advances. 2018 Nov 27;2[22]:3226-56), anticoagulation therapy (Blood Advances. 2018 Nov 27;2[22]:3257-91), pediatrics (Blood Advances. 2018 Nov 27;2[22]:3292-316), pregnancy (Blood Advances. 2018 Nov 27;2[22]:3317-59), and heparin-induced thrombocytopenia (Blood Advances. 2018 Nov 27;2[22]:3360-92).
Dr. Cushman, Dr. Lim, and Dr. Witt reported having no relevant disclosures. Dr. Cuker reported receiving research support from T2 Biosystems.

For patients with low pretest probability, the guidelines recommended the D-dimer test as the best first step. Further testing isn’t needed when the D-dimer is negative, noted Dr. Lim, a hematologist and professor at McMaster University, Hamilton, Ont.
The guidelines also recommended using ventilation-perfusion scintigraphy (V/Q scan) for imaging a pulmonary embolism over a CT scan, which uses more radiation. But V/Q scans are not ideal for assessing older patients or patients with lung disease, Dr. Lim cautioned.
Management
Management of VTE should occur, when feasible, through a specialized anticoagulation management service center, which can provide care that is best suited to the complexities of anticoagulation therapy. But it’s a level of care that many U.S. patients don’t currently receive and hence is an area ripe for growth, said Daniel M. Witt, PharmD, professor and vice-chair of pharmacotherapy at the University of Utah, Salt Lake City.
The guidelines recommended against bridging therapy with LMWH for most patients who need to stop warfarin when undergoing an invasive procedure. The guidelines also called for “thoughtful” use of anticoagulant reversal agents and advised that patients who survive a major bleed while on anticoagulation should often resume the anticoagulant once they are stabilized.
For patients who develop heparin-induced thrombocytopenia, the 4Ts score is the best way to make a more accurate diagnosis and boost the prospects for recovery, said Dr. Cuker (Blood. 2012 Nov 15;120[20]:4160-7). The guidelines cite several agents now available to treat this common complication, which affects about 1% of the 12 million Americans treated with heparin annually: argatroban, bivalirudin, danaparoid, fondaparinux, apixaban, dabigatran, edoxaban, and rivaroxaban.
ASH has a VTE website with links to detailed information for each of the guideline subcategories: prophylaxis in medical patients, diagnosis, therapy, heparin-induced thrombocytopenia, VTE in pregnancy, and VTE in children. The website indicates that additional guidelines will soon be released on managing VTE in patients with cancer, in patients with thrombophilia, and for prophylaxis in surgical patients, as well as further information on treatment. A spokesperson for ASH said that these additional documents will post sometime in 2019.
At the time of the release, the guidelines panel published six articles in the journal Blood Advances that detailed the guidelines and their documentation.
The articles include prophylaxis of medical patients (Blood Advances. 2018 Nov 27;2[22]:3198-225), diagnosis (Blood Advances. 2018 Nov 27;2[22]:3226-56), anticoagulation therapy (Blood Advances. 2018 Nov 27;2[22]:3257-91), pediatrics (Blood Advances. 2018 Nov 27;2[22]:3292-316), pregnancy (Blood Advances. 2018 Nov 27;2[22]:3317-59), and heparin-induced thrombocytopenia (Blood Advances. 2018 Nov 27;2[22]:3360-92).
Dr. Cushman, Dr. Lim, and Dr. Witt reported having no relevant disclosures. Dr. Cuker reported receiving research support from T2 Biosystems.
The new guidelines, released on Nov. 27, contain more than 150 individual recommendations, including sections devoted to managing venous thromboembolism (VTE) during pregnancy and in pediatric patients. Guideline highlights cited by some of the writing-panel participants included a high reliance on low-molecular-weight heparin (LMWH) agents as the preferred treatment for many patients, reliance on the D-dimer test to rule out VTE in patients with a low pretest probability of disease, and reliance on the 4Ts score to identify patients with heparin-induced thrombocytopenia.
The guidelines took more than 3 years to develop, an effort that began in 2015.
An updated set of VTE guidelines were needed because clinicians now have a “greater understanding of risk factors” for VTE as well as having “more options available for treating VTE, including new medications,” Adam C. Cuker, MD, cochair of the guideline-writing group and a hematologist and thrombosis specialist at the University of Pennsylvania, Philadelphia, said during a webcast to unveil the new guidelines.
Prevention
For preventing VTE in hospitalized medical patients the guidelines recommended initial assessment of the patient’s risk for both VTE and bleeding. Patients with a high bleeding risk who need VTE prevention should preferentially receive mechanical prophylaxis, either compression stockings or pneumatic sleeves. But in patients with a high VTE risk and an “acceptable” bleeding risk, prophylaxis with an anticoagulant is preferred over mechanical measures, said Mary Cushman, MD, professor and medical director of the thrombosis and hemostasis program at the University of Vermont, Burlington.
For prevention of VTE in medical inpatients, LMWH is preferred over unfractionated heparin because of its once-daily dosing and fewer complications, said Dr. Cushman, a member of the writing group. The panel also endorsed LMWH over a direct-acting oral anticoagulant, both during hospitalization and following discharge. The guidelines for prevention in medical patients explicitly “recommended against” using a direct-acting oral anticoagulant “over other treatments” both for hospitalized medical patients and after discharge, and the guidelines further recommend against extended prophylaxis after discharge with any other anticoagulant.
Another important takeaway from the prevention section was a statement that combining both mechanical and medical prophylaxis was not needed for medical inpatients. And once patients are discharged, if they take a long air trip they have no need for compression stockings or aspirin if their risk for thrombosis is not elevated. People with a “substantially increased” thrombosis risk “may benefit” from compression stockings or treatment with LMWH, Dr. Cushman said.

Tofacitinib and TNF inhibitors show similar VTE rates
CHICAGO – Rheumatoid arthritis patients treated with tofacitinib did not have a significantly increased incidence of hospitalization for venous thromboembolism, compared with patients treated with a tumor necrosis factor (TNF) inhibitor, in a study of more than 50,000 U.S. patients culled from a pair of health insurance databases.
The Janus kinase inhibitor class of agents, including tofacitinib (Xeljanz), has acquired a reputation for causing an excess of venous thromboembolic events (VTE) (Drug Saf. 2018 Jul;41[7]:645-53). To assess this in a real-world setting Seoyoung C. Kim, MD, and her associates took data from Medicare patients during 2012-2015 and from Truven MarketScan for commercially insured patients during 2012-2016 and derived a database of 16,091 RA patients on newly begun treatment with a TNF inhibitor and 995 newly begun on tofacitinib in the Medicare data, and 32,164 RA patients newly started on a TNF inhibitor and 1,910 on tofacitinib in the Truven database. The analysis excluded patients with a history of VTE.
Using propensity score–adjusted matching of patients in the two treatment arms in both of these databases, and using a VTE event – either a pulmonary embolism or deep-vein thrombosis that resulted in hospitalization – as the primary endpoint, the results showed statistically nonsignificant excesses of VTE in the patients treated with tofacitinib, compared with a TNF inhibitor, Dr. Kim reported in a poster she presented at the annual meeting of the American College of Rheumatology.
In the adjusted comparison, the Medicare data showed a nonsignificant 12% higher VTE rate in the tofacitinib-treated patients, while the Truven data showed a nonsignificant 55% higher rate of VTE during tofacitinib treatment. When the data were pooled, the result was a 33% higher rate of VTE while on tofacitinib treatment, which was not statistically significant.
Dr. Kim cautioned that the low rate of VTE events, especially among the patients on tofacitinib, limited the precision of the results. The combined data included 2,905 patients on tofacitinib treatment who had 15 VTE events, a rate of 0.77 events/100 person-years of follow-up. This compared with a rate of 0.52/100 person-years among patients on a TNF inhibitor. Thus, in both treatment groups the absolute VTE rate was low.
The most reliable finding from the analysis is that it “rules out a large increase in the risk for VTE events with tofacitinib,” said Dr. Kim, a rheumatologist at Brigham and Women’s Hospital in Boston.
The researchers also ran an analysis that included not only VTE events that resulted in hospitalization but also VTE events managed on an outpatient basis. Dr. Kim did not report the specific numbers involved in this calculation, but she reported that, when her group included both types of VTE events, the patients treated with tofacitinib had a nonsignificant 12% lower rate of events, compared with patients treated with a TNF inhibitor.

All patients with VTE have a high risk of recurrence
Recurrence risk is significant among all patients with venous thromboembolism (VTE), though recurrence is most frequent in patients with cancer-related VTE, according to a nationwide Danish study.
Ida Ehlers Albertsen, MD, of Aalborg (Denmark) University Hospital and her coauthors followed 73,993 patients who were diagnosed with incident VTE during January 2000–December 2015. The patients’ VTEs were classified as either cancer-related, unprovoked (occurring in patients without any provoking factors), or provoked (occurring in patients with one or more provoking factors, such as recent major surgery, recent fracture/trauma, obesity, or hormone replacement therapy).
The researchers found similar risks of recurrence among patients with unprovoked and provoked VTE at 6-month follow-up, with rates per 100 person-years of 6.80 and 6.92, respectively. By comparison, the recurrence rate for cancer-related VTE at 6 months was 9.06. The findings were reported in the American Journal of Medicine.
However, at 10-year follow-up the rates were 3.70 for cancer-related VTE, 2.84 for unprovoked VTE, and 2.22 for provoked VTE, which reinforces the belief that “unprovoked venous thromboembolism is associated with long-term higher risk of recurrence than provoked venous thromboembolism.”
Additionally, at 10-year follow-up, the absolute recurrence risk of cancer-related VTE and unprovoked VTE were both at approximately 20%, with recurrence risk of provoked VTE at just above 15%. Compared with the recurrence risk of provoked VTE at 10-year follow-up, the hazard ratios of cancer-related VTE and unprovoked VTE recurrence risk were 1.23 (95% confidence interval, 1.13-1.33) and 1.18 (95% CI, 1.13-1.24), respectively.
The coauthors observed several challenges in comparing their study to previous analyses on recurrent risk, noting that the definition of provoked VTE “varies throughout the literature” and that the majority of VTE studies “provide cumulative incidence proportions and not the actual rates.” They also stated that indefinite or extended therapy for all VTE patients comes with its own potential complications, even with the improved safety of non–vitamin K antagonist oral anticoagulants, writing that “treatment should be given to patients where the benefits outweigh the risks.”
Despite the differences in recurrence rates at 6-month and 10-year follow-up, the coauthors suggested that enough risk was present in all types to warrant additional studies and reconsider how VTE patients are categorized.
“A high recurrence risk in all types of venous thromboembolism indicates that further research is needed to optimize risk stratification for venous thromboembolism patients,” they wrote.
The study was partially funded by a grant from the Obel Family Foundation. Some authors reported financial disclosures related to Janssen, Bayer, Roche, and others.

EHR-guided strategy reduces postop VTE events
BOSTON – Avoiding could result in a reduction in VTE rates, a speaker said at the annual clinical congress of the American College of Surgeons.
The VTE rate dropped by about one-quarter in the trauma care pathway at the University of Pittsburgh Medical Center (UPMC) after implementation of algorithms to risk-stratify patients and guide nursing staff, said Matthew D. Neal, MD, FACS, the Roberta G. Simmons Assistant Professor of Surgery at the University of Pittsburgh.
By incorporating algorithms into the electronic health record (EHR), UPMC was able to realize a “dramatic” 72% reduction in missed doses, from 4,331 missed doses in 2014 to 1,193 in 2015, Dr. Neal told attendees in a session focused on hot topics in surgical patient safety.
That decrease in missed doses has translated into a decreased rate of VTE, from an already relatively low rate of 1.5% in 2015, to 1.1% in 2017, representing a 26.7% reduction, according to data Dr. Neal shared in his podium presentation.
“This has been a sustainable event for us, largely linked to the implementation of an EHR-guided risk assessment pathway to guide the implementation of VTE prophylaxis,” he said.
The change was safe, he added, noting that, since utilization of this pathway, there have been no significant increases in the rate of bleeding events among patients who have mandatory orders.
These results corroborate those of some previous investigations, including one key study from the Johns Hopkins Hospital that described the adoption of a mandatory computerized clinical decision support tool to improve adherence to best practices for VTE prophylaxis.
After incorporation of the tool in the computerized order entry system, there was a significant increase in VTE prophylaxis, translating into a significant drop in preventable harm from VTE, from 1.0% to 0.17% (P = .04), investigators reported in JAMA Surgery.
Reducing missed doses is one of the major contributing factors to decreased VTE rates, according to Dr. Neal.
Missed doses of enoxaparin correlate with increased incidence of deep vein thrombosis (DVT) in trauma and general surgery patients, according to results of one prospective study Dr. Neal described. In that study of 202 patients, reported in JAMA Surgery, DVTs were seen in 23.5% of patients with missed doses, compared with 4.8 for patients with no missed doses (P < .01).
“We need to understand how to risk assess and how to utilize our EHR as a tool,” Dr. Neal told attendees.
Dr. Neal reported disclosures related to Janssen Pharmaceuticals, CSL Behring, Accriva Diagnostics, and Haemonetics, as well as a U.S. patent for a treatment of infectious and inflammatory disorders, and laboratory funding from the National Institutes of Health, Department of Defense, and the Biomedical Advanced Research and Development Authority.

After incorporation of the tool in the computerized order entry system, there was a significant increase in VTE prophylaxis, translating into a significant drop in preventable harm from VTE, from 1.0% to 0.17% (P = .04), investigators reported in JAMA Surgery.
Reducing missed doses is one of the major contributing factors to decreased VTE rates, according to Dr. Neal.
Missed doses of enoxaparin correlate with increased incidence of deep vein thrombosis (DVT) in trauma and general surgery patients, according to results of one prospective study Dr. Neal described. In that study of 202 patients, reported in JAMA Surgery, DVTs were seen in 23.5% of patients with missed doses, compared with 4.8 for patients with no missed doses (P < .01).
“We need to understand how to risk assess and how to utilize our EHR as a tool,” Dr. Neal told attendees.
Dr. Neal reported disclosures related to Janssen Pharmaceuticals, CSL Behring, Accriva Diagnostics, and Haemonetics, as well as a U.S. patent for a treatment of infectious and inflammatory disorders, and laboratory funding from the National Institutes of Health, Department of Defense, and the Biomedical Advanced Research and Development Authority.

BOSTON – Avoiding could result in a reduction in VTE rates, a speaker said at the annual clinical congress of the American College of Surgeons.
The VTE rate dropped by about one-quarter in the trauma care pathway at the University of Pittsburgh Medical Center (UPMC) after implementation of algorithms to risk-stratify patients and guide nursing staff, said Matthew D. Neal, MD, FACS, the Roberta G. Simmons Assistant Professor of Surgery at the University of Pittsburgh.
By incorporating algorithms into the electronic health record (EHR), UPMC was able to realize a “dramatic” 72% reduction in missed doses, from 4,331 missed doses in 2014 to 1,193 in 2015, Dr. Neal told attendees in a session focused on hot topics in surgical patient safety.
That decrease in missed doses has translated into a decreased rate of VTE, from an already relatively low rate of 1.5% in 2015, to 1.1% in 2017, representing a 26.7% reduction, according to data Dr. Neal shared in his podium presentation.
“This has been a sustainable event for us, largely linked to the implementation of an EHR-guided risk assessment pathway to guide the implementation of VTE prophylaxis,” he said.
The change was safe, he added, noting that, since utilization of this pathway, there have been no significant increases in the rate of bleeding events among patients who have mandatory orders.

VTE risk may be high throughout disease course in uterine serous carcinoma
Uterine serous carcinoma patients may have a high risk of venous thromboembolism (VTE), not just in the postoperative period, but throughout the natural history of the disease, results of a retrospective analysis suggest.
Most patients developed VTE either before staging surgery or more than 6 months postoperatively, according to results of the analysis reported in Obstetrics & Gynecology.
Nearly one-third (31%) of the women developed VTE while receiving chemotherapy, reported Gregory M. Gressel, MD, a gynecologic oncology fellow at Montefiore Medical Center, New York, and his coinvestigators.
The risk was highest in women with cardiovascular disease, hypertension, and stage III and IV disease, they said.
“Although this is a retrospective study, it generates the hypothesis that venous thromboembolism prophylaxis may be beneficial in women with active uterine serous carcinoma, at least while receiving treatment such as neoadjuvant or adjuvant chemotherapy,” Dr. Gressel and his coauthors noted.
Historically, clinical practice guidelines have focused on risk stratification in the perioperative period due to the strong association between cancer-related VTE and surgery, the authors wrote.
To better assess the timing and risk factors associated with clot development, Dr. Gressel and his colleagues abstracted clinical data from the medical records of 413 patients with uterine serous carcinoma between 1999 and 2016 at one center in New York, about half of whom identified as black and one-quarter as Hispanic.
Eighty-four percent of the patients were diagnosed with VTE before or after the 6-week postoperative window when thromboprophylaxis typically is recommended, and 31% developed clots during chemotherapy, the investigators reported. The median time to clot development was 7.2 months after diagnosis, and, after excluding patients who developed clots preoperatively or during chemotherapy, the investigators found the median time from surgery to VTE was 13.2 months.
Patients with stage III and IV disease were, respectively, 2.6 and 4 times more likely to develop thrombosis, compared with patients with stage I disease. Conversely, age, body mass index, and race were not associated with VTE diagnosis.
Patients who developed VTE on chemotherapy had a median Khorana score of 1, which corresponds to an intermediate risk of VTE, the investigators said, adding that pharmacologic prophylaxis is recommended only in patients with scores of 3 or higher.
“Ours is not the first report to posit that currently available venous thromboembolism risk stratification tools are of limited utility in gynecologic oncology patients,” said Dr. Gressel and his coauthors.
However, larger prospective studies are needed, not only to look at the utility of Khorana scoring in this high-risk histologic subtype, they said, but also to test their hypothesis that VTE prophylaxis may be beneficial during chemotherapy or other active treatment.
Dr. Gressel and his colleagues reported no conflicts of interest. The study was supported by the National Institutes of Health and a grant from the National Center for Advancing Translational Science.

It has been reported in previous literature that the risk of developing VTE is typically within 48 hours of surgical staging, and guidelines have focused on risk factors to identify patients needing extended thromboprophylaxis after surgery. Therefore, Gressel et al. set forth to identify risk factors and timing of development of VTE in women with uterine serous carcinoma.
The study retrospectively evaluated 413 women with uterine serous cancer from 1999 to 2016. Of these, 70 women (about 17%) were diagnosed with a VTE. There was not a statistically significant association between age, body mass index, race, or surgical approach with risk of VTE. However, stage and/or having two or more medical comorbidities were significant. Compared with stage I patients, stage III and IV patients had a 2.6- and fourfold increase in risk, respectively. Not surprisingly, hypertension and cardiovascular disease (CVD) were independently associated with risk of VTE development; odds ratio 2.97 and 1.87, respectively. Interestingly, in the women diagnosed with VTE, 84% were outside the 6-week postoperative period and 31% occurred during chemotherapy treatment. The median time to develop VTE was 13.2 months and occurred sooner in women with advanced stage.
In this study, the majority of patients developed a VTE outside of the standard 28-day thromboprophylaxis window. This finding suggests that there is a subset of patients who would benefit from longer duration of thromboprophylaxis. Perhaps patients with hypertension, CVD, and/or advanced stage malignancy would benefit from thromboprophylaxis throughout their treatment.
Based on the data presented, at this time, we cannot recommend treating patients with the above risk factors during the entirety of their care. Although further studies and even a nomogram may help determine who is likely to benefit from prolonged prophylaxis, it is unknown if doing so would result in significant decreased morbidity or increased adverse events (e.g. bleeding, thrombocytopenia). However, this should remain a topic for further evaluation and providers should remain vigilant for prevention and diagnosis of VTE in at-risk patients by adhering to validated risk assessment tools and clinical evaluation.

Rivaroxaban gains indication for prevention of major cardiovascular events in CAD/PAD
announced on October 11.
when taken with aspirin, Janssen PharmaceuticalsThe Food and Drug Administration’s approval was based on a review of the 27,000-patient COMPASS trial, which showed last year that a low dosage of rivaroxaban (Xarelto) plus aspirin reduced the combined rate of cardiovascular disease events by 24% in patients with coronary artery disease and by 28% in participants with peripheral artery disease, compared with aspirin alone. (N Engl J Med. 2017 Oct 5;377[14]:1319-30)
The flip side to the reduction in COMPASS’s combined primary endpoint was a 51% increase in major bleeding. However, that bump did not translate to increases in fatal bleeds, intracerebral bleeds, or bleeding in other critical organs.
COMPASS (Cardiovascular Outcomes for People Using Anticoagulation Strategies) studied two dosages of rivaroxaban, 2.5 mg and 5 mg twice daily, and it was the lower dosage that did the trick. Until this approval, that formulation wasn’t available; Janssen announced the coming of the 2.5-mg pill in its release.
The new prescribing information states specifically that Xarelto 2.5 mg is indicated, in combination with aspirin, to reduce the risk of major cardiovascular events, cardiovascular death, MI, and stroke in patients with chronic coronary artery disease or peripheral artery disease.
This is the sixth indication for rivaroxaban, a factor Xa inhibitor that was first approved in 2011. It is also the first indication for cardiovascular prevention for any factor Xa inhibitor. Others on the U.S. market are apixaban (Eliquis), edoxaban (Savaysa), and betrixaban (Bevyxxa).
COMPASS was presented at the 2017 annual congress of the European Society of Cardiology. At that time, Eugene Braunwald, MD, of Harvard Medical School and Brigham and Women’s Hospital in Boston, commented that the trial produced “unambiguous results that should change guidelines and the management of stable coronary artery disease.” He added that the results are “an important step for thrombocardiology.”
