RESUMO
INTRODUCTION: Portal vein thrombosis in cirrhotic patients presents a significant clinical challenge. This study aims to (1) explore the impact of anticoagulation therapy on patient outcomes; (2) comparative outcomes in portal vein thrombosis treated between direct oral anticoagulant and Vitamin K Antagonist (VKA). MATERIALS AND METHODS: We leveraged the TriNetX database to analyze a cohort comprising 4224 patients with liver cirrhosis and PVT who were treated with anticoagulation, alongside a comparison group of 15,300 patients with the same conditions but not receiving anticoagulation therapy. RESULTS: The anticoagulated group showed a significant reduction in mortality (27.9 % vs. 34.2 %, HR = 0.723, 95 % CI: 0.678-0.770, P < 0.001). When comparing direct oral anticoagulant versus. VKA, in compensated liver cirrhosis, the direct oral anticoagulant group exhibited significantly lower mortality rates compared to VKA (17.7 % vs. 26.5 %, HR = 0.655, 95 % CI: 0.452-0.951, P = 0.025), with no significant difference in liver transplantation rates (4.0 % vs. 4.7 %, P = 0.080). In decompensated liver cirrhosis, the direct oral anticoagulant group exhibited lower mortality compared to the VKA group (23.6 % vs. 30.6 %, HR = 0.732, 95 % CI: 0.629-0.851, P < 0.001), and a higher frequency of liver transplantation was observed in the VKA group (10.6 % vs. 16.0 %, HR = 0.622, 95 % CI: 0.494-0.784, P < 0.001). Hospitalization rates were significantly lower in the direct oral anticoagulant group compared to the VKA group in decompensated cirrhosis (33.4 % vs. 38.3 %, HR = 0.830, 95 % CI: 0.695-0.992, P = 1.937). CONCLUSIONS: Our study offers compelling evidence supporting the use of anticoagulation therapy in liver cirrhosis with portal vein thrombosis. The use of DOACs in patients with both compensated and decompensated liver cirrhosis showed a marked mortality benefit.

INTRODUCTION: Gastrointestinal (GI) bleeding events (BEs) in von Willebrand disease (VWD) are difficult to diagnose and often recurrent. Limited data from clinical trials has led to lack of consensus on treatment options. AIM: Describe current treatments and outcomes for GI BEs in people with VWD. METHODS: This retrospective, observational, multicentre chart review study was conducted from January 2018 through December 2019 and included patients with inherited VWD with ≥1 GI BE in the preceding 5 years. Baseline characteristics, number and aetiology of BEs, associated GI-specific morbidities/lesions, treatment and outcomes were analysed descriptively. RESULTS: Sixty bleeds were reported in 20 patients with type 1 (20%), type 2 (50%) and type 3 (30%) VWD. During the 5-year study period, 31 (52%) BEs had one identified or suspected cause; multiple causes were reported in 11 (18%). Most GI BEs (72%) were treated with a combination of von Willebrand factor (VWF), antifibrinolytics and/or other haemostatic or non-haemostatic treatments. Time to resolution did not differ by VWF treatment use; however, BEs treated with non-VWF treatments tended to resolve later. In patients with GI-specific morbidities/lesions, 84% resolved with first-line treatment; time to resolution tended to be longer than in patients without such morbidities/lesions. Thirteen BEs occurred in patients receiving prophylaxis and 47 in patients receiving on-demand treatment; 18 BEs resulted in a switch to prophylaxis after bleed resolution. CONCLUSIONS: This study confirms the unmet need for the management of recurrent GI BEs in people with VWD and the need for prospective data, especially on prophylaxis.

In many patients referred with significant bleeding phenotype, laboratory testing fails to define any hemostatic abnormalities. Clinical practice with respect to diagnosis and management of this patient cohort poses significant clinical challenges. We recommend that bleeding history in these patients should be objectively assessed using the International Society on Thrombosis and Haemostasis (ISTH) bleeding assessment tool. Patients with increased bleeding assessment tool scores should progress to hemostasis laboratory testing. To diagnose bleeding disorder of unknown cause (BDUC), normal complete blood count, prothrombin time, activated partial thromboplastin time, thrombin time, von Willebrand factor antigen, von Willebrand factor function, coagulation factors VIII, IX, and XI, and platelet light transmission aggregometry should be the minimum laboratory assessment. In some laboratories, additional specialized hemostasis testing may be performed to identify other rare causes of bleeding. We recommend that patients with a significant bleeding phenotype but normal laboratory investigations should be registered with a diagnosis of BDUC in preference to other terminology. Global hemostatic tests and markers of fibrinolysis demonstrate variable abnormalities, and their clinical significance remains uncertain. Targeted genomic sequencing examining candidate hemostatic genes has a low diagnostic yield. Underlying BDUC should be considered in patients with heavy menstrual bleeding since delays in diagnosis often extend to many years and negatively impact quality of life. Treatment options for BDUC patients include tranexamic acid, desmopressin, and platelet transfusions.

INTRODUCTION: Gene therapy is now a reality for individuals with haemophilia, yet little is known regarding the quality-of-life impact of factor correction. As few data exist, and recognizing the analogy to liver transplantation (OLTX), we identified OLTX+ and OLTX- men in the ATHNdataset to compare post-OLTX factor VIII and IX on quality of life (QoL) by Haem-A-QoL and PROMIS-29. METHODS: OLTX- were matched to OLTX+ by age, race, and haemophilia type and severity. Deidentified demographic data, including post-transplant factor levels, genotype and target joint disease were analysed by descriptive statistics. Haem-A-Qol and PROMIS-29 were compared in OLTX+ and OLTX- by student's t-test and univariate regression models. RESULTS: Of 86 people with haemophilia A (HA) or haemophilia B (HB) cared for at 10 haemophilia treatment centers (HTCs), 21 (24.4%) OLTX+ and 65 (75.6%) OLTX- were identified. OLTX+ and OLTX- had a similar frequency of target joint disease (p = .806), HA genotypes, null versus non-null (p = .696), and HIV infection (p = .316). At a median 9.2 years post-OLTX, median FVIII, .63 IU/mL [IQR 0.52-0.97] and FIX, .91 IU/mL [IQR .63-1.32], Haem-A-QoL, PROMIS-29, and HOT scores were comparable. Severe HA/HB had lower post-OLTX 'dealing with haemophilia' scores (p = .022) and higher 'sports and leisure' (p = .010) and 'view of yourself' scores (p = .024) than OLTX+ non-severe participants. Non-caucasian OLTX+ had significantly lower scores in sports and leisure (p = .042), future expectations (p = .021) and total score (p = .010). CONCLUSION: Nine years after OLTX, QoL is comparable to OLTX-, but significantly better in OLTX+ with severe than non-severe disease and in caucasians than non-caucasians.

ABSTRACT: Advanced practice providers (APPs) are critical to the hematology workforce. However, there is limited knowledge about APPs in hematology regarding specialty-specific training, scope of practice, challenges and opportunities in APP-physician interactions, and involvement with the American Society of Hematology (ASH). We conducted APP and physician focus groups to elucidate major themes in these areas and used results to inform development of 2 national surveys, 1 for APPs and 1 for physicians who work with APPs. The APP survey was distributed to members of the Advanced Practitioner Society of Hematology and Oncology, and the physician survey was distributed to physician members of ASH. A total of 841 APPs and 1334 physicians completed the surveys. APPs reported most hematology-specific knowledge was obtained via on-the-job training and felt additional APP-focused training would be helpful (as did physicians). Nearly all APPs and physicians agreed that APPs were an integral part of their organizations and that physician-APP collaborations were generally positive. A total of 42.1% of APPs and 29.3% of physicians reported burnout, and >50% of physicians felt that working with APPs had reduced their burnout. Both physicians and APPs reported interest in additional resources including "best practice" guidelines for APP-physician collaboration, APP access to hematology educational resources (both existing and newly developed resources for physicians and trainees), and greater APP integration into national specialty-specific professional organizations including APP-focused sessions at conferences. Professional organizations such as ASH are well positioned to address these areas.

Acquired bleeding disorders because of an autoimmune phenomenon are rare events. Acquired von Willebrand disease (aVWD) has been estimated as having a prevalence of 400 per million in the general population. Acquired hemophilia A (AHA), the most common of the acquired hemophilias, has an estimated incidence of 1.3-1.5 cases per million per year. Immune checkpoint inhibitors (ICI) targeting PD-1, PD-L1, and CTLA-4 are being used with increasing frequency for hematologic and oncologic disorders. Acquired hemophilias and aVWD have been reported with the use of ICI therapy. We performed a systematic review of the literature to identify cases of acquired bleeding disorders with ICI therapy and contribute our own institution's experience with a case of AHA after pembrolizumab therapy. Six cases of AHA, one case of aVWD, and one case of factor V inhibitor were identified in the literature. Inhibitors were successfully eradicated in five of the eight cases identified. We propose that a centralized registry, possibly through the Scientific and Standardization Subcommittee on Plasma Coagulation Inhibitors through the International Society on Thrombosis and Hemostasis (ISTH), be developed to record treatment and outcomes of this rare ICI complication in order to prognosticate risk and better understand optimal treatment strategies.

BACKGROUND: Excessive or abnormal mucocutaneous bleeding (MCB) may impact all aspects of the physical and psychosocial wellbeing of those who live with it (PWMCB). The evidence base for the optimal diagnosis and management of disorders such as inherited platelet disorders, hereditary hemorrhagic telangiectasia (HHT), hypermobility spectrum disorders (HSD), Ehlers-Danlos syndromes (EDS), and von Willebrand disease (VWD) remains thin with enormous potential for targeted research. RESEARCH DESIGN AND METHODS: National Hemophilia Foundation and American Thrombosis and Hemostasis Network initiated the development of a National Research Blueprint for Inherited Bleeding Disorders with extensive all-stakeholder consultations to identify the priorities of people with inherited bleeding disorders and those who care for them. They recruited multidisciplinary expert working groups (WG) to distill community-identified priorities into concrete research questions and score their feasibility, impact, and risk. RESULTS: WG2 detailed 38 high priority research questions concerning the biology of MCB, VWD, inherited qualitative platelet function defects, HDS/EDS, HHT, bleeding disorder of unknown cause, novel therapeutics, and aging. CONCLUSIONS: Improving our understanding of the basic biology of MCB, large cohort longitudinal natural history studies, collaboration, and creative approaches to novel therapeutics will be important in maximizing the benefit of future research for the entire MCB community.
More people experience mucocutaneous bleeding (MCB), affecting tissues like skin and gums, than have hemophilia A or B. MCB is not understood as well as hemophilia. Common types of MCB include nosebleeds, bleeding gums, heavy menstrual bleeding, and digestive tract bleeding. Mucocutaneous inherited bleeding disorders include inherited platelet disorders, hereditary hemorrhagic telangiectasia (HHT), hypermobility spectrum disorders (HSD) and Ehlers-Danlos syndromes (EDS), von Willebrand Disease (VWD), and others. Diagnosing and treating MCB is complicated and sometimes medical providers dismiss the bleeding that patients report when they cannot find a medical explanation for it. Many people with mucocutaneous bleeding (PWMCB) do not receive the care they need; for example, women with VWD live with symptoms for, on average, 16 years before they are diagnosed in the US. This struggle to obtain care has important negative impacts on patients' physical and psychological health and their quality-of-life. The National Hemophilia Foundation (NHF), a large US bleeding disorders patient advocacy organization, set out to develop a National Research Blueprint for Inherited Bleeding Disorders focused on community priorities. They brought together a group of patients, providers, and researchers with MCB expertise to identify the research that would most improve the lives of PWMCB through targeted and accessible diagnostics and therapies. We report in this paper that research is needed to better understand the biology of MCB and to define the mechanisms of disease in these disorders. We also describe high priority research questions for each of the main disorders, novel therapeutics, and aging.

For reproductive-aged women, the symptom of heavy menstrual bleeding is highly prevalent and a major contributor to iron deficiency and its most severe manifestation, iron deficiency anemia. It is recognized that these 2 clinical entities are not only highly prevalent, but their interrelationship is poorly appreciated and frequently normalized by society, healthcare providers, and affected girls and women themselves. Both heavy menstrual bleeding and iron deficiency, with or without anemia, adversely impact quality of life-heavy menstrual bleeding during the episodes of bleeding and iron deficiency on a daily basis. These combined issues adversely affect the lives of reproductive-aged girls and women of all ages, from menarche to menopause, and their often-insidious nature frequently leads to normalization. The effects on cognitive function and the related work and school absenteeism and presenteeism can undermine the efforts and function of women in all walks of life, be they students, educators, employers, or employees. There is also an increasing body of evidence that suggests that iron deficiency, even in early pregnancy, may adversely impact fetal neurodevelopment with enduring effects on a spectrum of cognitive and psychological disorders, critically important evidence that begs the normalization of iron stores in reproductive-aged women. The authors seek to raise individual, societal, and professional awareness of this underappreciated situation in a fashion that leads to meaningful and evidence-based changes in clinical guidance and healthcare policy directed at preventing, screening, diagnosing, and appropriately managing both disorders. This manuscript provides evidence supporting the need for action and describes the elements necessary to address this pervasive set of conditions that not only affect reproductive-aged girls and women but also the lives of children everywhere.

INTRODUCTION: Women and girls with bleeding disorders face multiple bleeding challenges throughout their life. The most significant morbidity and mortality are due to heavy menstrual bleeding and postpartum hemorrhage in their reproductive years. The ASH/ISTH/NHF/WFH 2021 guidelines on diagnosing and managing von Willebrand disease (VWD) provide several new updates. AREAS COVERED: Women with VWD have a higher prevalence of heavy menstrual bleeding. The subpopulation of adolescents is particularly vulnerable, as the diagnosis is often delayed with increased comorbidity of iron deficiency anemia and associated symptoms. A detailed review is done on the prevalence of bleeding-related complications, especially heavy menstrual bleeding (HMB) and post-partum hemorrhage (PPH). The management strategies are also reviewed in detail, with a specific focus on the target factor levels and the use of antifibrinolytics. EXPERT OPINION: The 2021 ASH/ISTH/NHF/WFH diagnostic and management recommendations are reviewed with a specific focus on hormonal methods of HMB management and antifibrinolytics in this situation. The reviewed topics include neuraxial anesthesia, factor cutoff, and tranexamic acid use in the postpartum period.

OBJECTIVE: We assessed sociodemographic and clinical characteristics associated with depression and anxiety in individuals with Von Willebrand disease (VWD) aged ≥12 years. METHODS: The study collected data on patients' sociodemographic, joint problems and health-related quality of life (HRQoL) using EQ-5D-3L, 8-item patient health questionnaire for depression and 7-item Generalized Anxiety Disorder Questionnaire from participants in seven geographically diverse US haemophilia treatment centres. RESULTS: Analyses included 77 participants. The rates of depression and anxiety were 63.6% and 58.3%, respectively. Persons with low VWF displayed higher rates of depression (86.7%) or anxiety (69.2%) compared to those with VWD (58.1%, p = .04 for depression, and 55.9%, p = .38 for anxiety). Logistic regression analyses demonstrated that having joint problems (odds ratio [OR] = 6.3, confidence interval [CI] = 2.0-20.1) was the most important variable associated with depression, followed by being single, divorced, widowed, or separated in adult participants or parents of participants age < 18 years (OR = 7.0, CI = 1.7-29.0. The most important variable associated with anxiety was being single or lacking a partner (OR = 10.8, CI = 2.5-47.5), followed by age 12-17 years old (OR = 6.7, CI = 1.6-26.9), or having worse health compared to 3-months ago (OR = 12.3, CI = 1.3-116.2). Mean covariates adjusted EQ visual analogue scale score was significantly lower among persons with depression (68.77 ± 3.15 vs. 77.58 ± 4.24, p = .03) than those without depression. CONCLUSIONS: Our study revealed concerning levels of depression and anxiety in this VWD sample. Lack of social support was determined an important factor associated with depression and anxiety in this sample. Mental health screening is critical in VWD clinical evaluation and care.

The challenge of pregnancy can be significant to the point of being life-threatening in a woman with a bleeding disorder. Additionally there can be a risk to the fetus and the neonate. A hemostatic defect can affect the course of the pregnancy, but the impact is most feared around delivery in the immediate and the extended post partum period, requiring rapid identification and prompt referral to a hematologist for assistance in management. Identifying the type of congenital bleeding disorder and knowing its inheritance pattern is crucial during counseling prior to conception and in preparation for delivery. A comprehensive approach by a specialized and experienced team in a tertiary care center with access to adequate laboratory monitoring and therapies can facilitate the process. The multidisciplinary team should include a hematologist, an obstetrician, a pediatric hematologist, an anesthesiologist, and in select cases a clinical geneticist and a maternal fetal medicine specialist. In this review article, we will detail the diagnostic path and management of pregnancy and delivery in women with some inherited bleeding disorders, in particular those affected by hemophilia A (HA), hemophilia B (HB), and von Willebrand disease (VWD).
RESUMO
Prior studies report a greater incidence of second primary malignancy (SPM) among patients with myeloproliferative neoplasms, although the true risk in primary myelofibrosis (PMF) has not been elucidated. We utilized the Surveillance, Epidemiology, and End Results database to evaluate the risk of SPM in PMF patients and analyzed the effects of sociodemographic factors on the risk of SPM. Out of 5273 patients, 385 patients (7.30%) developed SPM. SPM occurred at SIR of 1.95 (95% CI 1.76-2.15) and AER of 149.01 per 10,000 population. A significantly higher incidence of melanoma (SIR 1.76, 95% CI 1.01-2.86), lymphoma (SIR 3.38, 95% CI 2.28-4.83), and leukemia (SIR 27.19, 95% CI 23.09-31.81) was observed. The risk was significantly higher in patients ≤60 years, males, chemotherapy recipients, within 5 years of PMF diagnosis, and for PMF diagnosed after 2009.
