Medical homes a boon to patients with bleeding disorders
As bleeding disorders are increasingly recognized as a national health priority, hematologists are focusing on how the patient-centered medical home – a widely accepted concept in primary care and in some specialties – can improve outcomes and quality life for their patients.
The patient-centered medical home is a model of health care delivery in which patients receive comprehensive, accessible care that is fully integrated across all providers and elements of a healthcare system.1 The concept emerged in the 1960s among pediatricians seeking to better coordinate care for children with complex medical needs. Since then, the patient-centered medical home has become a globally recognized standard – not only in primary care, but also in specialties such as endocrinology, oncology, and geriatric medicine. The movement to establish medical homes for patients with bleeding disorders is more recent and is receiving national attention.
Why a medical home?
The advent of prophylactic therapies for bleeding disorders has vastly improved the outlook for many patients compared to just a few decades ago. However, treatment options remain limited, and patients who have severe disease or complications – such as an inadequate treatment response or the development of inhibitory antibodies to replacement clotting factors – are at risk for recurrent breakthrough bleeding that can lead to synovitis and ultimately culminate in progressive, irreversible joint damage. The resulting pain and limitation of motion greatly compromises patients’ quality of life across physical, psychological, and social domains, undermines their ability to live and work independently, and greatly increases treatment costs.2-4 Family members, too, face high stress and lower quality of life when they struggle to obtain and manage treatment while caring for loved ones with bleeding disorders.5
For patients with bleeding disorders, a patient-centered medical home can help address or surmount these challenges, said Amy Shapiro, MD, medical director of the Indiana Hemophilia and Thrombosis Center in Indianapolis, Ind., which was the first hemophilia treatment center in the country to be formally certified as a medical home.
Dr. Shapiro explained that a patient-centered medical home leverages the care of an integrated multidisciplinary team to help optimize therapies and patient outcomes across all domains of life. She sees the medical home concept as a natural fit for patients with bleeding disorders, given the complexity of their needs and the number of specialties involved. “When you have hemophilia, you don’t just need a hematologist to manage your care. You need nurses, physical therapists, and social workers. You need coordinated care for genetic counseling. You also need to coordinate dental hygiene and surgical interventions, if these are required. Patients need nutrition counseling, and they may need assistance with education or career options if too many days are missed from work or school. Patients or their families may need counseling on choosing the right insurance program so they don’t choose a plan that may create more hardships for them because of their chronic disorder.”
Meeting these needs requires the help of an integrated care team, which many individuals with bleeding disorders lack. “If you are just out there in the community and you have medical issues that need to be dealt with, often the individuals themselves have to coordinate their own care, including their medications and their appointments with different specialists,” said Dr. Shapiro. “For example, a care provider may tell a patient that they need a physical therapist and give them some names, and then the patient has to take it from there and not only find the provider, but also determine if their insurance provides coverage.”
A medical home takes a completely different approach, she explained. “At my center, when we say you need a physical therapist, we have a physical therapist on staff. Our therapist provides an assessment and determines the need for ongoing PT and whether that can be done at home with a plan and intermittent oversight, or whether the patient needs a referral, and whether the person the patient is referred to needs education on how to provide PT for someone with hemophilia. A medical home provides all this in one place. It is a place where patients know they will receive either direct services, or support to shepherd their care and outcomes, and oversight of that support as well.”
Few studies have directly assessed the medical home model in the setting of bleeding disorders, but a number have evaluated the impact of integrated care, a more general term for the practice of coordinating multidisciplinary care to improve access and outcomes while eliminating redundancies and unnecessary costs. In a recent systematic review and meta-analysis of 27 nonrandomized studies of patients with hemophilia, integrated care was linked to lower mortality, fewer emergency room visits and hospitalizations, shorter lengths of stay in the hospital, and fewer missed days of school and work.6 Such findings, combined with promising outcomes data from studies of patient-centered medical homes in other disease settings, suggest that the patient-centered medical home can significantly benefit patients with bleeding disorders and their families and caregivers.
Creating a medical home
Establishing a patient-centered medical home can be challenging, involving a plethora of stakeholders and a considerable investment of time, energy, and resources. Organizations such as the National Committee for Quality Assurance and the Accreditation Association for Ambulatory Health Care have formal certification programs to help ensure that an inpatient or outpatient center that calls itself a medical home truly is one.7-8
The certification process requires centers to document activities in areas such as patients’ rights and responsibilities, administration and governance, patient and care team relationships, clinical records and other health information, and quality, comprehensiveness, continuity, and accessibility.7 Achieving certification is rigorous, often requiring centers to document compliance with more than 100 policies, procedures, and standards.
For the Indiana Hemophilia and Thrombosis Center, becoming certified as a medical home “was a multiyear process and an ongoing process,” said Dr. Shapiro. “It involves documentation of quality improvement initiatives, obtaining input from patients to document their satisfaction, and looking at all types of systems within our center and how we integrate care so that all those systems function together. It’s a difficult process, but treatment centers are a medical home for patients with bleeding disorders, and this is an effort to provide some documentation on a national level of how we’re doing everything that we are doing.”
She noted that the process of obtaining medical home certification may require an even higher level of commitment if a bleeding disorder (hemophilia) treatment center is embedded in a university or academic medical center. In this case, more stakeholders are involved, and more hoops may need to be jumped through to implement processes that meet medical home standards while still adhering to any requirements at the organizational level.
Certification programs for patient-centered medical homes are not designed around specific disorders or diseases, but a closer look at their compliance metrics underscores how medical homes can benefit patients with bleeding disorders. For example, to receive medical home certification from the Accreditation Association for Ambulatory Health Care, a center needs to be able to document that patients’ care is not transferred without first making arrangements with a receiving health care provider, that the quality improvement programs are peer-led, and that these programs assess and address diverse measures of clinical performance, cost-effectiveness, and administrative functioning.7-9
Medical homes, the NHPCC, and Healthy People 2030
Creating patient-centered medical homes for patients with bleeding disorders is now a quality improvement objective of the National Hemophilia Program Coordinating Center, or NHPCC. Established in 2012 and funded by the federal Health Resources and Services Administration, the NHPCC partners with the eight regional hemophilia networks and more than 140 federally funded hemophilia treatment centers across the United States to identify gaps, standardize and improve access to care, and share and promote best practices for the treatment and management of blood disorders.10
In the United States, receiving care in a hemophilia treatment center (which, despite its name, typically offers care for other disorders such as von Willebrand disease) has been linked to lower mortality and fewer hospitalizations related to bleeding complications.11 To continue to improve on these outcomes, the NHPCC, regional networks, and hemophilia treatment centers are prioritizing medical homes and ranking their establishments alongside core objectives such as bettering patient and family engagement and improving the transition from pediatric to adult care.12
As part of this quality improvement work, the NHPCC, regional leadership, and hemophilia treatment centers meet regularly to identify needs and priorities, plan programs, and ensure that each center is meeting the goals and objectives set out by its federal grant.13 Such partnerships help improve and integrate care within a coordinated national framework, Dr. Shapiro said. “We all are charged with this same mission,” she added. “That doesn’t mean that every treatment center looks exactly the same, has the same number of staff, or does everything the same way, but we all have the same mission, and we know what that is. That is the work of the NHPCC, to determine and document that and help level and improve care throughout the country.”
The NHPCC also engages other stakeholders, including consumer agencies and professional organizations. Recent achievements have included a first-ever national patient needs assessment, a tandem technical needs assessment of hemophilia treatment centers, an educational outreach program for genetic counselors, a webinar on transitioning care for adolescents, a national survey of the federal 340B Drug Pricing Program, and a survey of minority patients to identify and characterize problems such as language and insurance barriers, the lack of culturally appropriate educational materials on blood disorders, and difficulties getting transportation to treatment centers or educational programs.14
In part because of this advocacy work, the U.S. Department of Health and Human Services recently included hemophilia for the first time in Healthy People, its evidence-based set of decade-long objectives aimed at improving the health of all Americans. In Healthy People 2030, the specific objective for hemophilia is to reduce the proportion of patients with severe disease who experience more than four joint bleeds per year to 13.3% (the current estimate is 16.9%).15
For Healthy People to prioritize hemophilia for the first time alongside much more common conditions such as diabetes and heart disease reflects the challenges of managing bleeding disorders and the efforts by the NHPCC and other stakeholders to raise awareness about current needs. To track progress in meeting the Healthy People 2030 objective, the NHPCC will work with federal partners to analyze patient-level data gathered through the Centers for Disease Control’s Community Counts Registry for Bleeding Disorders Surveillance program, which collects data from hemophilia treatment centers across the United States and includes patients with all levels of disease severity.
“The inclusion of bleeding disorders in Healthy People 2030 is really very significant,” said Dr. Shapiro. “These are disorders that affect less than 200,000 Americans, which is the definition of a rare disease in this context. To have hemophilia considered as a national priority is very important, not only for hemophilia, but also for other rare diseases that may in the future also be considered as being as of national importance in this way.”

This finding comes from a review of 10 years of clinical trials by the Children’s Oncology Group (COG), which showed that, among patients with B-ALL, 5-year event-free survival (EFS) and overall survival (OS) were inferior with boys, compared with girls, even when adjusted for prognostic factors, reported Sumit Gupta, MD, PhD, FRCPC, from the Hospital for Sick Children in Toronto.
“Inferior outcomes, although small in absolute terms, continue to exist among boys versus girls despite modern therapy and after adjusting for other risk factors. These persist also despite the longer duration of therapy among boys,” he said in an oral abstract presentation during the annual meeting of the American Society of Pediatric Hematology/Oncology. (Abstract 2025).
Among pediatric patients with T-cell lineage ALL (T-ALL), however, there were no significant sex-based differences in either EFS or OS, he said.
Although survival for children with ALL has continued to improve, previous studies found inferior survival outcomes in boys, and suggested that the difference might be explained by imbalances in risk factors.
To see whether sex-based disparities persist with modern intensive therapy protocols after adjustment for risk factors, and to determine whether there are sex-based differences in toxicities or patterns of treatment failure, Dr. Gupta and colleagues created a cohort of all patients age 1-30 years enrolled in frontline COG trial for B-ALL and T-ALL from 2004 to 2014.
During this period, boys received an extra year of maintenance. Cranial radiation was limited to B-ALL patients with slow treatment responses and central nervous system status 3, signifying definite CNS involvement. Among patients with T-ALL, cranial radiation was given to all intermediate- and high-risk patients.
Sex differences small, but significant
The investigators identified a total of 8,202 patients (4,463 males and 3,739 females) with B-ALL, and 1,562 (1,161 males and 401 females) with T-ALL. Boys were likely to be older (P < .0001), and to have a small but significantly greater likelihood of having unfavorable B-ALL cytogenetics, compared with girls (P = .05).
Boys with B-ALL were less likely to be negative for minimal residual disease (76.1% vs. 78.1%, P = .04), but the opposite was true for those with T-ALL (59% vs. 56.8%, P = .01).
As noted before, among pediatric patients with B-ALL, EFS and OS were both inferior for males, with a hazard ratio for higher EFS rates in girls of 1.19 (P = .001) and a HR for OS of 1.17 (P = .046).
Both EFS and OS were similar between the sexes among patients with T-ALL.
The differences in EFS in patients with B-ALL was attributable to higher CNS relapses among boys (4.2% vs. 2.5%, P < .0001). The CNS relapses occurred at a median of 2.5 years in boys versus 2.1 years in girls, although most relapses occurred during therapy.
There were no differences in cumulative isolated bone marrow relapses, however.
Treatment-related mortality rates were the same, but osteonecrosis rates were significantly lower for boys, with a 5-year cumulative incidence of 5.2% versus 6.7% for girls (P = .001).
Possible explanations
Dr. Gupta noted that the inferior outcomes among boys may be attributable to extramedullary relapses among patients with B-ALL.
In addition, the lack of sex-based differences in T-ALL may be caused in part by the increased use of CNS radiation in this population. Previous studies in which CNS radiation was omitted showed an increase in CNS relapsed rates among boys but not girls, he pointed out.
“This does imply that in the more recent generation of T-lineage ALL treatment trials that we’ll need to monitor sex-based differences in outcome, as fewer and fewer patients with T-ALL disease received cranial radiation in these more recent trials and in contemporary therapy,” he said.
One possible mechanism for sex-based outcome differences might be differences in steroid metabolism, as suggested by the higher osteonecrosis rate among girls, he added.
In the question-and-answer following the presentation, William G. Woods, MD, from Emory University, Atlanta, asked what role testicular relapse played in outcomes.
Dr. Gupta replied that the investigators had considered that the excess risk for extramedullary relapse in boys might be accounted for by testicular relapse, but “when you take away testicular relapse from those numbers and really just concentrate on CNS, it’s still that substantial difference when you’re talking about B-lineage disease.”
In patients with T-ALL as well, CNS relapse was more common in boys after controlling for testicular relapse, he said.
Another audience member asked whether the data suggest a benefit to treating boys with CNS-penetrating drugs such as dexamethasone or high-dose methotrexate,
Dr. Gupta said that it’s still uncertain whether it is clinically sound to subject a boy with otherwise–standard-risk disease to more intensive high-risk therapy, given the relatively small absolute differences in outcomes between the sexes.
The study was supported by grants from the National Cancer Institute and the St. Baldrick’s Foundation. Dr. Gupta, Dr. Woods, and Dr. Meret had no relevant conflicts of interest to report.

FDA approves new treatment option for rare anemia
A rare, life-threatening anemia now has a new treatment option. The Food and Drug Administration announced the approval of pegcetacoplan (Empaveli) injection to treat adults with paroxysmal nocturnal hemoglobinuria (PNH). Pegcetacoplan is the first PNH treatment that binds to complement protein C3, according to the FDA announcement. Complement protein C3 is a key component of host immunity and defense.
Special concern
Because of the risk of severe side effects, the drug is available only through a restricted program under a risk evaluation and mitigation strategy (REMS). Serious infections can occur in patients taking pegcetacoplan that can become life-threatening or fatal if not treated early. According to the FDA, REMS are designed to reinforce medication use behaviors and actions that support the safe use of that medication, and only a few drugs require a REMS.
The most common other side effects are injection site reactions, diarrhea, abdominal pain, and fatigue.
Pegcetacoplan was approved based upon a study of 80 patients with PNH and anemia who had been taking eculizumab, a previously approved treatment. During 16 weeks of treatment, patients in the pegcetacoplan group had an average increase in their hemoglobin of 2.4 g/dL, while patients in the eculizumab group had an average decrease in their hemoglobin of 1.5 g/dL.
About the disease
PNH is caused by gene mutations that affect red blood cells, causing them to be defective and susceptible to destruction by a patient’s own immune system. Red blood cells in people with these mutations are defective and can be destroyed by the immune system, causing anemia.
Other symptoms include blood clots and destruction of bone marrow. The disease affects 1-1.5 people per million, with diagnosis typically occurring around ages 35-40, and a median survival of only 10 years after diagnosis, according to the FDA.

Omics analysis links blood type to COVID-19
A new analysis of gene expression and protein content in lung and blood tissue suggests that certain variants of the ABO gene, which plays a central role in determining blood type, may also influence susceptibility to COVID-19. Researchers at the University of British Columbia, Vancouver, analyzed data from three studies to link gene and protein expression in lungs and blood with genetic regions associated with COVID-19 susceptibility.
“These genes may also prove to be good markers for disease as well as potential drug targets,” said lead author Ana Hernandez Cordero, PhD, postdoctoral fellow with the Center for Heart Lung Innovation, University of British Columbia, in a statement. Dr. Cordero presented the study at the American Thoracic Society’s virtual international conference.
Dr. Cordero noted that genomewide association studies have been used to identify genetic regions associated with COVID-19 susceptibility, but they cannot be used to identify specific genes. To pinpoint genes, the researchers employed integrated genomics, which combines Bayesian colocalization summary-based Mendelian randomization and Mendelian randomization.
Searching for candidate genes
The researchers combined genetic data and transcriptomics data, which are a measurement of the messenger RNA produced in a cell. Messenger RNA is used as a blueprint for protein production. The genetics data came from the COVID-19 Host Genetics Initiative genomewide association meta-analysis version 4 (patients with COVID-19 vs. patients without COVID-19). Blood transcriptomics data came from the INTERVAL study (n = 3301), and lung transcriptomics data came from the Lung eQTL study (n = 1038). “From the integration of these three datasets we identified the candidate genes that are most likely to influence COVID-19 through gene expression. We further investigated the most consistent candidate genes and tested the causal association between their plasma protein levels and COVID-19 susceptibility using Bayesian colocalization and Mendelian randomization,” said Dr. Cordero during her talk.
Susceptibility drivers
The researchers identified six genes expressed in the lung and five expressed in blood that colocalized with COVID-19 susceptibility loci. They found that an increase in plasma levels of ABO was associated with greater risk for COVID-19 (Mendelian randomization, P = .000025) and that expression of the SLC6A20 gene in the lung was also associated with higher COVID-19 risk. They also found novel associations at genes associated with respiratory diseases, such as asthma, as well as genes associated with the host immune responses, such as neutrophil and eosinophil counts.
Possibly protective?
Within the ABO gene, the research also turned up evidence that blood type O may be protective against COVID-19. “The most significant variant used for the Mendelian randomization test was in complete linkage disagreement with the variant responsible for the blood type O genotype, conferring reduced risk,” said Dr. Cordero.
The study’s method is a powerful technique, said Jeremy Alexander Hirota, PhD, who was asked to comment. “The present study uses integrative omics to determine COVID-19 susceptibility factors which would have been challenging to identify with a single technology,” said Dr. Hirota, who is an assistant professor of medicine at McMaster University, Hamilton, Ont.; an adjunct professor of biology at the University of Waterloo (Ont.); and an affiliate professor of medicine at the University of British Columbia. He trained with the senior author of the study but was not directly involved in the research.
The host response is widely believed to be most responsible for the symptoms of COVID-19, so it isn’t surprising that host genes can be identified, according to Dr. Hirota. The identification of variants in the ABO protein is interesting, though. It suggests ‘that systemic effects beyond respiratory mucosal immunity are a driver for susceptibility.’ To my understanding, ABO protein is not expressed in the respiratory mucosa, which is a common site of first contact for SARS-CoV-2. The links between blood ABO levels and initial infection of the respiratory mucosa by SARS-CoV-2 are unclear,” he said.
Severity link needed
Dr. Hirota also said that although the study points toward associations with susceptibility to COVID-19, it isn’t clear from the available data whether such associations are related to severity of disease. “If the [patients with gene variants] are more susceptible but [the disease is] less severe, then the results need to be interpreted accordingly. If the susceptibility is increased and the severity is also increased, maybe measured by increased risk for ICU admission, ventilator use, or mortality, then the work carries a much more important message. Future studies extending this work and integrating measures of severity are warranted to better understand the clinical utility of these findings for managing COVID-19 patients optimally,” said Dr. Hirota.
It’s also unclear whether the study populations are reflective of the populations that are currently at highest risk for COVID-19, such as residents of India, where the burden of disease is currently severe.
Dr. Cordero and Dr. Hirota disclosed no relevant financial relationships.

The links between blood ABO levels and initial infection of the respiratory mucosa by SARS-CoV-2 are unclear,” he said.
Severity link needed
Dr. Hirota also said that although the study points toward associations with susceptibility to COVID-19, it isn’t clear from the available data whether such associations are related to severity of disease. “If the [patients with gene variants] are more susceptible but [the disease is] less severe, then the results need to be interpreted accordingly. If the susceptibility is increased and the severity is also increased, maybe measured by increased risk for ICU admission, ventilator use, or mortality, then the work carries a much more important message. Future studies extending this work and integrating measures of severity are warranted to better understand the clinical utility of these findings for managing COVID-19 patients optimally,” said Dr. Hirota.
It’s also unclear whether the study populations are reflective of the populations that are currently at highest risk for COVID-19, such as residents of India, where the burden of disease is currently severe.
Dr. Cordero and Dr. Hirota disclosed no relevant financial relationships.

Patients with CLL have significantly reduced response to COVID-19 vaccine
Patients with chronic lymphocytic leukemia (CLL) have increased risk for severe COVID-19 disease as well as mortality.
Such patients are likely to have compromised immune systems, making them respond poorly to vaccines, as has been seen in studies involving pneumococcal, hepatitis B, and influenza A and B vaccination.
In order to determine if vaccination against COVID-19 disease will be effective among these patients, researchers performed a study to determine the efficacy of a single COVID-19 vaccine in patients with CLL. They found that the response rate of patients with CLL to vaccination was significantly lower than that of healthy controls, according to the study published in Blood Advances.
Study details
The study (NCT04746092) assessed the humoral immune responses to BNT162b2 mRNA COVID-19 (Pfizer) vaccination in adult patients with CLL and compared responses with those obtained in age-matched healthy controls. Patients received two vaccine doses, 21 days apart, and antibody titers were measured 2-3 weeks after administration of the second dose, according to Yair Herishanu, MD, of the Tel-Aviv Sourasky Medical Center, Tel Aviv University, and colleagues.
Troubling results
The researchers found an antibody-mediated response to the BNT162b2 mRNA COVID-19 vaccine in only 66 of 167 (39.5%) of all patients with CLL. The response rate of 52 of these responding patients with CLL to the vaccine was significantly lower than that occurring in 52 age- and sex-matched healthy controls (52% vs. 100%, respectively; adjusted odds ratio, 0.010; 95% confidence interval, 0.001-0.162; P < .001).
Among the patients with CLL, the response rate was highest in those who obtained clinical remission after treatment (79.2%), followed by 55.2% in treatment-naive patients, and it was only 16% in patients under treatment at the time of vaccination.
In patients treated with either BTK inhibitors or venetoclax with and without anti-CD20 antibody, response rates were low (16.0% and 13.6%, respectively). In particular, none of the patients exposed to anti-CD20 antibodies less than 12 months prior to vaccination responded, according to the researchers.
Multivariate analysis showed that the independent predictors of a vaccine response were age (65 years or younger; odds ratio, 3.17; P = .025), sex (women; OR, 3.66; P = .006), lack of active therapy (including treatment naive and previously treated patients; OR 6.59; P < .001), IgG levels 550 mg/dL or greater (OR, 3.70; P = .037), and IgM levels 40mg/dL or greater (OR, 2.92; P = .017).
Within a median follow-up period of 75 days since the first vaccine dose, none of the CLL patients developed COVID-19 infection, the researchers reported.
“Vaccinated patients with CLL should continue to adhere to masking, social distancing, and vaccination of their close contacts should be strongly recommended. Serological tests after the second injection of the COVID-19 vaccine can provide valuable information to the individual patient and perhaps, may be integrated in future clinical decisions,” the researchers concluded.
The study was sponsored by the Tel-Aviv Sourasky Medical Center. The authors reported that they had no conflicts of interest.

Health costs over 25 times higher for hemophilia B patients than controls
As the burden of hemophilia B in patients increases from mild to severe forms of the disease, the already high economic cost of treatment rises significantly, according to a large retrospective database study.
Researchers developed four profile categories (mild, moderate, moderate-severe, and severe) for men with hemophilia B on the basis of the frequency of hemorrhage events and factor IX replacement claims as identified from the IBM MarketScan database (June 2011–February 2019). The mean annual health care resource use (HRU) and costs were compared between 5,454 patients with hemophilia B and 1:1 demographically matched controls.
Economic burden
Total health care costs rose with increasingly severe clinical profiles, with hemophilia-related treatments being the primary cost driver, researchers led by Tyler W. Buckner, MD, of the University of Colorado at Denver, Aurora, wrote in Blood Advances.
This was particularly true among patients with more severe clinical profiles, who were more likely to be on prophylaxis with all of its associated costs.
The mean overall total costs incurred by patients with hemophilia B over the study period were $201,635 versus $7,879 for matched controls, a more than 25-fold difference (P < .001). In addition, across all four clinical profiles categories, all-cause total costs, medical costs, and pharmacy costs were significantly higher among patients with hemophilia B than matched controls (P < .001 for all), the researchers added.
Annual total health care costs also increased with increasing severity of hemophilia B clinical profiles, ranging from $80,811 and $137,455 in the mild and moderate groups to $251,619 and $632,088 in the moderate-severe and severe groups, respectively.
“Hemophilia-related treatments represented the primary cost driver. HRU was uniformly higher among patients with hemophilia B across clinical profiles, medical service types examined, and with respect to opioid use. The significant burden highlights that unmet needs remain in hemophilia B,” the researchers concluded.

Trends in the management of pulmonary embolism
One of the newest trends in pulmonary embolism management is treatment of cancer associated venous thromboembolism (VTE) which encompasses deep vein thrombosis (DVT) and PE. Following the clinical management of cancer-associated venous thromboembolism in the hospital, direct oral anticoagulant therapy at discharge is your starting point, except in cases of intact luminal cancers, Scott Kaatz, DO, MSc, FACP, SFHM, said during SHM Converge, the annual conference of the Society of Hospital Medicine.
Dr. Kaatz, of the division of hospital medicine at Henry Ford Hospital, Detroit, based his remarks on emerging recommendations from leading medical societies on the topic, as well as a one-page algorithm from the Anticoagulation Forum that can be accessed at https://acforum-excellence.org/Resource-Center/resource_files/1638-2020-11-30-121425.pdf.
For the short-term treatment of VTE (3-6 months) for patients with active cancer, the American Society of Hematology guideline panel suggests direct oral anticoagulants, such as apixaban, edoxaban, or rivaroxaban, over low-molecular-weight heparin (LMWH) – a conditional recommendation based on low certainty in the evidence of effects.
Dr. Kaatz also discussed the latest recommendations regarding length of VTE treatment. After completion of primary treatment for patients with DVT and/or PE provoked by a chronic risk factor such as a surgery, pregnancy, or having a leg in a cast, the ASH guideline panel suggests indefinite antithrombotic therapy over stopping anticoagulation. “On the other hand, patients with DVT and/or PE provoked by a transient factor typically do not require antithrombotic therapy after completion of primary treatment,” said Dr. Kaatz, who is also a clinical professor of medicine at Wayne State University, Detroit.
After completion of primary treatment for patients with unprovoked DVT and/or PE, the ASH guideline panel suggests indefinite antithrombotic therapy over stopping anticoagulation. “The recommendation does not apply to patients who have a high risk for bleeding complications,” he noted.
Transient or reversible risk factors should be also considered in length of VTE treatment. For example, according to guidelines from the European Society of Cardiology, the estimated risk for long-term VTE recurrence is high (defined as greater than 8% per year) for patients with active cancer, for patients with one or more previous episodes of VTE in the absence of a major transient or reversible factor, and for those with antiphospholipid antibody syndrome.
Dr. Kaatz also highlighted recommendations for the acute treatment of intermediate risk, or submassive PE. The ESC guidelines state that if anticoagulation is initiated parenterally, LMWH or fondaparinux is recommended over unfractionated heparin (UFH) for most patients. “The reason for that is, one drug-use evaluation study found that, after 24 hours using UFH, only about 24% of patients had reached their therapeutic goal,” Dr. Kaatz said. Guidelines for intermediate risk patients from ASH recommend anticoagulation as your starting point, while thrombolysis is reasonable to consider for submassive PE and low risk for bleeding in selected younger patients or for patients at high risk for decompensation because of concomitant cardiopulmonary disease. “The bleeding rates get much higher in patients over age 65,” he said.
Another resource Dr. Kaatz mentioned is the Pulmonary Embolism Response Team (PERT) Consortium, which was developed after initial efforts of a multidisciplinary team of physicians at Massachusetts General Hospital. The first PERT sought to coordinate and expedite the treatment of pulmonary embolus with a team of physicians from a variety of specialties. In 2019 the PERT Consortium published guidelines on the diagnosis, treatment, and follow-up of acute PE. “It includes detailed algorithms that are a little different from the ASH and ESC guidelines,” Dr. Kaatz said.

He has also received research funding from Janssen, Bristol-Myers Squibb, and Osmosis.

Pediatric cancer survivors at risk for opioid misuse
Survivors of childhood cancers are at increased risk for prescription opioid misuse compared with their peers, a review of a claims database revealed.
Among more than 8,000 patients age 21 or younger who had completed treatment for hematologic, central nervous system, bone, or gonadal cancers, survivors were significantly more likely than were their peers to have an opioid prescription, longer duration of prescription, and higher daily doses of opioids, and to have opioid prescriptions overlapping for a week or more, reported Xu Ji, PhD, of Emory University in Atlanta.
Teenage and young adult patients were at higher risk than were patients younger than 12, and the risk was highest among patients who had been treated for bone malignancies, as well as those who had undergone any hematopoietic stem cell transplant.
“These findings suggest that health care providers who regularly see survivors should explore nonopioid options to help prevent opioid misuse, and screen for potential misuse in those who actually receive opioids,” she said in an oral abstract presented during the annual meeting of the American Society of Pediatric Hematology/Oncology.
“This is a really important topic, and something that’s probably been underinvestigated and underexplored in our patient population,” said session comoderator Sheri Spunt, MD, Endowed Professor of Pediatric Cancer at Stanford (Calif.) University.
Database review
Dr. Ji and colleagues used the IBM MarketScan Commercial Claims and Encounters database from 2009 to 2018 to examine prescription opioid use, potential misuse, and substance use disorders in pediatric cancer survivors in the first year after completion of therapy, and to identify factors associated with risk for misuse or substance use disorders. Specifically, the period of interest was the first year after completion of all treatments, including surgery, chemotherapy, radiation, and stem cell transplant (Abstract 2015).
They looked at deidentified records on any opioid prescription and for treatment of any opioid use or substance use disorder (alcohol, psychotherapeutic drugs, marijuana, or illicit drug use disorders).
They defined indicators of potential misuse as either prescriptions for long-acting or extended-release opioids for acute pain conditions; opioid and benzodiazepine prescriptions overlapping by a week or more; opioid prescriptions overlapping by a week or more; high daily opioid dosage (prescribed daily dose of 100 or greater morphine milligram equivalent [MME]; and/or opioid dose escalation (an increase of at least 50% in mean MMEs per month twice consecutively within 1 year).
They compared outcomes between a total of 8,635 survivors and 44,175 controls, matched on a 1:5 basis with survivors by age, sex, and region, and continuous enrollment during the 1-year posttherapy period.
In each of three age categories – 0 to 11 years, 12 to 17 years, and 18 years and older – survivors were significantly more likely to have received an opioid prescription, at 15% for the youngest survivors vs. 2% of controls, 25% vs. 8% for 12- to 17-year-olds, and 28% vs. 12% for those 18 and older (P < .01 for all three comparisons).
Survivors were also significantly more likely to have any indicator of potential misuse (1.6% vs. 0.1%, 4.6% vs. 0.5%, and 7.4% vs. 1.2%, respectively, P < .001 for all) and both the youngest and oldest groups (but not 12- to 17-year-olds) were significantly more like to have opioid or substance use disorder (0.4% vs. 0% for 0-11 years, 5.76% vs. 4.2% for 18 years and older, P < .001 for both).
Among patients with any opioid prescription, survivors were significantly more likely than were controls of any age to have indicators for potential misuse. For example, 13% of survivors aged 18 years and older had prescriptions for high opioid doses, compared with 5% of controls, and 12% had prescription overlap, vs. 2%.
Compared with patients with leukemia, patients treated for bone malignancies had a 6% greater risk for having any indicator of misuse, while patients with other malignancies were at slightly lower risk for misuse than those who completed leukemia therapy.
Patients who received any stem cell transplant had an 8.4% greater risk for misuse compared with patients who had surgery only.
Opioids pre- and posttreatment?
“Being someone who takes care of a lot of bone cancer patients, I do see patients with these issues,” Dr. Spunt said.
Audience member Jack H. Staddon, MD, PhD, of the Billings (Montana) Clinic, noted the possibility that opioid use during treatment may have been carried on into the posttreatment period, and asked whether use of narcotics during treatment was an independent risk factor for posttreatment narcotic use or misuse.
The researchers plan to investigate this question in future studies, Dr. Ji replied.

Survivors of childhood cancers are at increased risk for prescription opioid misuse compared with their peers, a review of a claims database revealed.
Among more than 8,000 patients age 21 or younger who had completed treatment for hematologic, central nervous system, bone, or gonadal cancers, survivors were significantly more likely than were their peers to have an opioid prescription, longer duration of prescription, and higher daily doses of opioids, and to have opioid prescriptions overlapping for a week or more, reported Xu Ji, PhD, of Emory University in Atlanta.
Teenage and young adult patients were at higher risk than were patients younger than 12, and the risk was highest among patients who had been treated for bone malignancies, as well as those who had undergone any hematopoietic stem cell transplant.
“These findings suggest that health care providers who regularly see survivors should explore nonopioid options to help prevent opioid misuse, and screen for potential misuse in those who actually receive opioids,” she said in an oral abstract presented during the annual meeting of the American Society of Pediatric Hematology/Oncology.
“This is a really important topic, and something that’s probably been underinvestigated and underexplored in our patient population,” said session comoderator Sheri Spunt, MD, Endowed Professor of Pediatric Cancer at Stanford (Calif.) University.
Database review
Dr. Ji and colleagues used the IBM MarketScan Commercial Claims and Encounters database from 2009 to 2018 to examine prescription opioid use, potential misuse, and substance use disorders in pediatric cancer survivors in the first year after completion of therapy, and to identify factors associated with risk for misuse or substance use disorders. Specifically, the period of interest was the first year after completion of all treatments, including surgery, chemotherapy, radiation, and stem cell transplant (Abstract 2015).
They looked at deidentified records on any opioid prescription and for treatment of any opioid use or substance use disorder (alcohol, psychotherapeutic drugs, marijuana, or illicit drug use disorders).
They defined indicators of potential misuse as either prescriptions for long-acting or extended-release opioids for acute pain conditions; opioid and benzodiazepine prescriptions overlapping by a week or more; opioid prescriptions overlapping by a week or more; high daily opioid dosage (prescribed daily dose of 100 or greater morphine milligram equivalent [MME]; and/or opioid dose escalation (an increase of at least 50% in mean MMEs per month twice consecutively within 1 year).
They compared outcomes between a total of 8,635 survivors and 44,175 controls, matched on a 1:5 basis with survivors by age, sex, and region, and continuous enrollment during the 1-year posttherapy period.
In each of three age categories – 0 to 11 years, 12 to 17 years, and 18 years and older – survivors were significantly more likely to have received an opioid prescription, at 15% for the youngest survivors vs. 2% of controls, 25% vs. 8% for 12- to 17-year-olds, and 28% vs. 12% for those 18 and older (P < .01 for all three comparisons).
Survivors were also significantly more likely to have any indicator of potential misuse (1.6% vs. 0.1%, 4.6% vs. 0.5%, and 7.4% vs. 1.2%, respectively, P < .001 for all) and both the youngest and oldest groups (but not 12- to 17-year-olds) were significantly more like to have opioid or substance use disorder (0.4% vs. 0% for 0-11 years, 5.76% vs. 4.2% for 18 years and older, P < .001 for both).

High variability found in studies assessing hemophilia-related pain
Chronic pain is a common condition among people with hemophilia and is associated with joint deterioration because of repeated joint bleeds. This systematic review and meta-analysis aimed to determine the prevalence of chronic pain because of hemophilia and to analyze its interference in the lives of patients, according to Ana Cristina Paredes, a PhD student at the University of Minho, Braga, Portugal, and colleagues.
The manuscripts included in the study, which was published online in the Journal of Pain, were mostly observational, cross-sectional studies and one prospective investigation, published between 2009 and 2019.
The issue of pain is particularly important among people with hemophilia, as many adult patients suffer from distinct degrees of arthropathy and associated chronic pain, due to the lifelong occurrence of hemarthrosis, the authors noted. In an important distinction, according to the authors, people with hemophilia may therefore experience both acute pain during bleeds and chronic pain caused by joint deterioration. Acute pain ceases with the resolution of the bleeding episode, but the chronic pain is significantly more challenging, since it persists in time and may trigger changes in the nervous system, leading to peripheral or central sensitization.
Data in the assessed studies were collected from a variety of sources: hemophilia centers, online surveys, by mail, or through a national database, with return rates ranging from 29.2% to 98%. Overall, these studies comprised 4,772 adults, with individual sample sizes ranging from 21 to 2,253 patients, the authors added.
Conflicting results
Overall, there was a widely varying prevalence of hemophilia-related chronic pain reported across studies. Additionally, methodologies and sample characteristics varied widely. The meta-analyses revealed high heterogeneity between studies, and, therefore, pooled prevalence estimates values must be interpreted with caution, the authors stated.
All of the 11 selected studies included for meta-analysis and review reported on the prevalence of chronic pain caused by hemophilia. Chronic pain was assessed using direct questions developed by the authors in eight studies and using the European Haemophilia Therapy Standardization Board definition in three studies. The prevalence for global samples ranged widely from 17% to 84%.
Although there was high heterogeneity, the random-effects meta-analysis including all studies demonstrated a pooled prevalence of 46% of patients reporting chronic pain. Subgroup analyses of studies including all disease severities (mild, moderate, and severe; seven studies) revealed a pooled prevalence of 48%, but also with high heterogeneity. Looking at severe patients only (six studies), the chronic pain prevalence ranged from 33% to 86.4%, with a pooled prevalence of 53% and high heterogeneity, the authors added.
The wide disparity of the chronic pain prevalence seen across the studies is likely because of the fact that some investigations inquired about pain without distinguishing between acute (hemarthrosis-related) or chronic (arthropathy-related) pain, and without clarifying if the only focus is pain caused by hemophilia, or including all causes of pain complaints, according to the researchers.
“Concerning hemophilia-related chronic pain interference, it is striking that the existing literature does not distinguish between the impact of acute or chronic pain. Such a distinction is needed and should be made in future studies to ensure accurate accounts of hemophilia-related pain and to fully understand its interference according to the type of pain (acute vs. chronic). This information is relevant to promote targeted and effective treatment approaches,” the researchers concluded.
The research was supported by a Novo Nordisk HERO Research Grant 2015, the Portuguese Foundation for Science and Technology, and the Foundation for Science and Technology in Portugal. The authors declared they had no conflicts of interest.

AHA guidance on blood clots linked to COVID-19 vaccine
A newly released report is offering guidance concerning rare conditions associated with COVID-19 as well as vaccines against the virus.
The report was released April 29, 2021, by the American Heart Association/American Stroke Association Stroke Council Leadership in answer to the decision April 23 by the Centers for Disease Control and Prevention and the Food and Drug Administration to lift an earlier “pause” in administration of the Johnson & Johnson (Janssen) vaccine.
That pause had been put in place after reports were received of a possible association between the J&J vaccine and cerebral venous sinus thrombosis (CVST) and thrombosis-thrombocytopenia syndrome (TTS, blood clots plus low blood platelets). CVST and TTS were also linked to patients in Europe and Canada who received the AstraZeneca COVID-19 vaccine.
However, the new report noted that these conditions are very rare.
“The risk of CVST due to infection with COVID-19 is 8-10 times higher than the risk of CVST after receiving a COVID-19 vaccine,” lead author Karen L. Furie, MD, chair of the department of neurology at Brown University, Providence, R.I., said in a press release.
“The public can be reassured by the CDC’s and FDA’s investigation and these statistics – the likelihood of developing CVST after a COVID-19 vaccine is extremely low,” said Dr. Furie, adding that the authors “urge all adults to receive any of the approved COVID-19 vaccines.”
The new guidance, which was published online April 29, 2021, in Stroke, discusses signs and symptoms of CVST and TTS, as well as vaccine-induced immune thrombotic thrombocytopenia (VITT). It also recommends best options for treating these conditions.
Assessing 81 million patients
In their analysis, the investigators assessed a database of 59 health care organizations and 81 million patients, 98% of whom were in the United States.
Of almost 514,000 patients diagnosed with COVID-19 between January 2020 and March 2021, 20 also received a diagnosis of CVST.
Among about 490,000 adults who received either the Pfizer or Moderna vaccines, there were no diagnosed cases of thrombocytopenia.
Dr. Furie reiterated that CVST blood clots “are very rare adverse events,” but recommended that any patient in the ED with a suspected clot should be screened immediately to determine if they received a COVID vaccine during the previous few weeks.
For those who have recently received the COVID-19 vaccine, a suspected clot should be treated with nonheparin anticoagulants, Dr. Furie said.
“No heparin products in any dose should be given for suspected CVST, TTS, or VITT. With the right treatment, most patients can have a full recovery,” she added. The report includes additional, detailed treatment recommendations if one of these conditions are suspected.
Rare events
The authors noted that cases of TTS/VITT occurred up to 2.5 weeks after receiving the J&J vaccine in the United States and up to 3.5 weeks after receiving the AstraZeneca vaccine in Europe.
An April 23 report from the CDC and FDA noted that, out of almost 7 million adults who received the J&J vaccine, the agencies investigated only 15 reported cases of TTS.
An April 7 report from the European Medicines Agency noted that, out of more than 25 million people who received the AstraZeneca vaccine in the European Union, it found 62 cases of CVST.
A statement put out by the American Heart Association/American Stroke Association urges “everyone to receive a COVID-19 vaccine” as soon as possible.
“We are confident the benefits of vaccination far exceed the very small, rare risks,” the organizations said. “The risks of vaccination are also far smaller than the risk of COVID-19 and its potentially fatal consequences.”
