Thrombotic Disease in Hemophilic Patients: Is This a Paradox in a State of Hypocoagulability? Diagnostics (Basel) 2024; 14:286.

Abstract
Hemophilia patients have a deficiency in or dysfunction of clotting factors, which can lead to a bleeding tendency. However, paradoxically, some hemophilia patients may also be at an increased risk of developing thrombotic events such as deep vein thrombosis or pulmonary embolism. The pathophysiology of thrombosis in hemophilia patients is not fully understood, but it is thought to involve a complex interplay of various factors, including the severity of the hemophilia, the presence of other risk factors such as obesity, smoking, or the use of hormonal therapies, and the presence of certain genetic mutations that increase the risk of thrombosis. In addition, it has been suggested that the use of clotting factor replacement therapy, which is a standard treatment for hemophilia, may also contribute to the development of thrombosis in some cases.

Abstract
Hemophilia A is an inherited insufficiency of Factor VIII (FVIII), one of the critical clotting factors. The gold standard for the management of moderate-to-severe hemophilia A is prophylaxis using regular replacement therapy with clotting factor concentrates. Compared with conventional treatment, extended half-life products reduce the burden of frequent factor replacement injections. Of note, up to 30% of patients with hemophilia A receiving prophylactic factor infusions develop "inhibitors," neutralizing anti-FVIII autoantibodies. Therapeutic options for patients with hemophilia A and inhibitors include the immune tolerance induction (ie, eradication of inhibitors) and the management of acute bleeds with bypassing agents and/or emicizumab. Emicizumab is a biphasic monoclonal antibody mimicking activated FVIII, approved for patients with hemophilia A with/without inhibitors. Gene therapy is an emerging therapy for hemophilia A, essentially curing patients with hemophilia A or transforming them to a milder phenotype by establishing continuous endogenous expression of FVIII after one-time treatment.

Current and Emerging Approaches for Pain Management in Hemophilic Arthropathy. Pain Ther 2022; 11:1-15. [PMID: 35020184 PMCID: PMC8861243 DOI: 10.1007/s40122-021-00345-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Accepted: 12/07/2021] [Indexed: 12/26/2022] Open
Abstract
Introduction Hemophilia is an inherited bleeding hematological disorder characterized by the partial or complete deficiency of clotting factor VIII or IX. Hemophilic arthropathy is the consequence of repeated joint bleeding (hemarthrosis) and its management is based on the prevention of acute bleeding through the administration of the deficient clotting factor concentrate or non-factor therapies. In addition, the management of acute and chronic pain is pivotal in hemophilic arthropathy in order to restore function and allow rehabilitation of the joint.
Methods We conducted a qualitative review of the literature regarding current and emerging strategies for pain treatment in hemophilic arthropathy. This review considers systemic and local pharmacological and non-pharmacological interventions for acute and chronic pain management.
Results In hemophilic arthropathy, pain management is based on analgesics such as paracetamol, which represents the first choice for acute and chronic pain in adults and children, in association with opioids for adults. Non-steroidal anti-inflammatory drugs inhibit platelet function, so that the currently preferred drugs are short courses of cyclooxygenase 2 inhibitors. Local treatment with intra-articular injections of corticosteroids is an option for refractory cases and physiotherapy has an important role after hemarthrosis and for the long-term management of chronic pain for both pediatric and adult patients.
Conclusions The management of pain in hemophilia requires more standardization. Meanwhile, the safest drugs should be used at the lowest effective dosage and for periods as short as possible. For the non-pharmacological management of pain in these patients, a multidisciplinary team including hematologists, orthopedic surgeons, rheumatologists, and physiotherapists is warranted.

Abstract
The prospect of hemophilia patients has dramatically improved in the last few decades with the introduction of various interventions that can effectively treat or prevent their bleeding risk. The life expectancy of patients can now reach that of the healthy population, but this has paved the way for several previously unrecognized morbidities to manifest in older adults with hemophilia. Such clinical complications are attributed to suboptimal management or poor access to effective therapy during childhood as well as chronicity and prolonged exposure to the underlying pathophysiology of the disease and its treatment. Complications common in the aging population are also becoming increasingly relevant in this vulnerable patient subgroup. In this review, we highlight peculiarities of such morbidities including chronic viral infections and liver disease, debilitating joint impairment and bone disease, cardiovascular and chronic kidney disease, and cancers. We also reflect on topics of special interest in adulthood such as sexuality.

Abstract
Comprehensive evidence-based guidelines and well-validated assessment scales for pain in people with hemophilia (PwH) are needed. Here, we report 28 statements covering five topics on pain assessment and management in pediatric and adult PwH that were developed by 60 Italian hemophilia specialists during a Delphi consensus process. Overall, a clear consensus was achieved for 19 of the 28 statements. Consensus was reached on all statements on the topic of pain assessment and quality of life (QoL), including the need for regular pain assessment on a quantitative scale, the importance of distinguishing between different pain types, and the need to evaluate the impact of pain on patient QoL. The other four topics concerned acute and chronic pain management in adults and in children. Consensus was reached on statements regarding non-pharmacologic treatment and the use of first-line paracetamol (acetaminophen). There was a lack of consensus regarding the use of non-steroidal anti-inflammatory drugs, cyclooxygenase-2 inhibitors, or opioids.

Abstract
Novel candidates of thiazolo[4,5-d]pyrimidines (9a-l) were synthesized and their structures were elucidated by spectral and elemental analyses. All the novel derivatives were screened for their cyclooxygenase inhibitory effect, anti-inflammatory activity and ulcerogenic liability. All the new compounds exhibited anti-inflammatory activity, especially 1-(4-[7-(4-nitrophenyl)-5-thioxo-5,6-dihydro-3H-thiazolo[4,5-d]pyrimidin-2-ylideneamino]phenyl)ethanone (9g) was the most active derivative with 57%, 88% and 88% inhibition of inflammation after 1, 3 and 5h, respectively. Furthermore, this derivative 9g recorded higher anti-inflammatory activity than celecoxib which showed 43%, 43% and 54% inhibition after 1, 3 and 5h, sequentially. Moreover, the target derivatives 9a-l demonstrated moderate to high potent inhibitory action towards COX-2 (IC50 = 0.87-3.78 µM), in particular, the derivatives 9e (IC50 = 0.92 µM), 9g (IC50 = 0.87 µM) and 9k (IC50 = 1.02 µM) recorded higher COX-2 inhibitory effect than the selective COX-2 inhibitor drug celecoxib (IC50 = 1.11 µM). The in vivo potent compounds (9e, 9g and 9k) caused variable ulceration effect (ulcer index = 5-12.25) in comparison to that of celecoxib (ulcer index = 3). Molecular docking was performed to the most potent COX-2 inhibitors (9e, 9g and 9k) to explore the binding mode of these derivatives with Cyclooxygenase-2 enzyme.

Abstract
In recent decades, several improvements in hemophilia care have resulted in increased quality of life and life expectancy for those affected by this inherited hemorrhagic condition. Nowadays, individuals with hemophilia enjoy a life expectancy at birth close to that of males in the general population. As a consequence of the increasing age of the hemophilia population, a growing number of these patients develop age-related co-morbidities, such as cardiovascular disease and cancer, the management of which represents a new challenge for caregivers at hemophilia treatment centers. This narrative review focuses on the clinical problems arising in older people with hemophilia, with particular attention to the optimal therapeutic strategies.

Abstract
Joint pain secondary to chronic arthropathy represents one of the most common and debilitating complications of haemophilia, often requiring analgesic care. When compared with nonselective non-steroidal anti-inflammatory drugs (ns-NSAIDs), selective COX-2 inhibitors (coxibs) offer the major advantage of not increasing the bleeding risk, thus being a better choice of analgesics for haemophilia patients. However, several studies have highlighted the cardiovascular risks posed by coxibs and NSAIDs. Given the assumed protection against thrombosis conferred by the deficiency in coagulation factors VIII or IX, these precautions regarding the use of coxibs and NSAIDs have never really been taken into account in haemophilia management. However, contrary to what has long been suspected, haemophilia patients are indeed affected by the same cardiovascular risk factors as nonhaemophiliac patients. Further studies should be conducted to evaluate the impact of NSAIDs on cardiovascular risks and the prevalence of hypertension in haemophilia patients.

Abstract
Although the funding of rare diseases such as haemophilia in developing countries remains a low priority, pressures on the funding of haemophilia treatment are also emerging in developed economies affected by the global economic downturn and the other demands on health care budgets. This is leading advisory bodies and payers alike to explore the tools of Health Technology Assessment (HTAs) in deriving recommendations for reimbursement policies. In particular, the use of cost utility analysis (CUA) in deriving costs per quality adjusted life year (QALY) for different interventions is being used to rank interventions in order of priorities relative to a threshold cost per QALY. In these exercises, rare chronic disorders such as haemophilia emerge as particularly unattractive propositions for reimbursement, as the accepted methodology of deriving a CUA. For e.g. the use of prophylaxis in haemophilia leads to a range of costs/QALY which exceed the willingness to pay thresholds of most payers. In this commentary, we review the principles utilized in a recent systematic review of the use of haemophilia products carried out in Sweden as part of an HTA. We suggest that ranking haemophilia related interventions with the standard interventions of therapeutics and public health in CUA comparisons is inappropriate. Given that haemophilia treatment is a form of blood replacement therapy, we propose that such comparisons should be made with the interventions of mainstream blood transfusion. We suggest that unequivocally effective treatments such as haemophilia therapies should be assessed differently from mainstream interventions, that new methodologies are required for these kinds of diseases and that evidence of a societal willingness to support people with rare disorders needs to be recognized when reimbursement policies are developed.

Abstract
The prospects for many boys born with hemophilia today include a normal life expectancy and minimal to no joint disease. However, despite the availability of safe replacement clotting factor concentrates and effective antiviral treatment, the aging patient with hemophilia today faces many challenges. These include management of their hemophilia as well as the same age-related health issues as experienced in the general population. While increasing, data on the prevalence of comorbidities and their management in the hemophilia population remain limited. This review will focus on issues related to management of hemophilia and complications of cardiovascular, musculoskeletal, hepatic, and renal disease. Available research is summarized and potential approaches to management are discussed.

Abstract
Abstract
Improvements in hemophilia care and antiviral treatments have resulted in increases in median life expectancy for persons with congenital hemophilia A and B. Currently, 2% of hemophilia A and B patients surveyed in US comprehensive hemophilia treatment centers are 65 years of age or older and 15% are 45 years or older. Many of the complications of hemophilia, including intracranial hemorrhage, joint disease, and inhibitor development, increase with increasing age. Hepatocellular carcinoma and end-stage liver disease are increasing in the older hemophilia population due to infection with hepatitis C (HCV) and HCV/HIV coinfection. Older hemophilia patients also now face the same medical conditions associated with aging in the general population, including cardiovascular disease and cancer. Complex hemostatic management, sometimes in conjunction with antithrombotic management, with extensive cross-specialty clinical and laboratory coordination may be required for the care of the older hemophilia patient. Because elderly hemophilia patients currently represent a small portion of the overall hemophilia population, there is little in the way of clinical data to guide recommendations. Registry databases and cooperative group studies are needed for the development of evidence-based guidelines for the older hemophilia population, which is anticipated to expand in the future.

Older patients with hemophilia face many challenges related not only to hemophilia but also to general comorbidity associated with aging. Patients with hemophilia often have known risk factors for cardiovascular disease, such as hypertension and hepatitis C virus (HCV) infection, which may counteract any protective effects bestowed by the hypocoagulable state. Arthritis and joint disease are common and contribute to disability and pain. The high prevalence of chronic HCV infection has led to an increased risk for liver failure and hepatocellular carcinoma. Renal function and urological disorders are a concern in these patients, and issues related to sexuality are an important but often-overlooked issue. The use of routine procedures for general health maintenance in the elderly (e.g. colonoscopy) can be more complex in patients with hemophilia due to the inherent risk of bleeding, and serious disorders such as malignancy can be overlooked if signs of abnormal bleeding are attributed to hemophilia, rather than to cancer. Prospective studies are needed to address these challenges so that evidence-based guidance can be given to clinicians who treat older patients with hemophilia.

Abstract
Abstract
In persons with hemophilia, life expectancy is now approaching that of the general male population, at least in countries that can afford regular replacement therapy with coagulation factor concentrates. The new challenges for comprehensive treatment centers are thus to provide optimal health care for this aging population of patients, who often present not only with the comorbidities typically associated with hemophilia (arthropathy, chronic pain, blood-borne infections), but also with common age-related illnesses such as cardiovascular disease and cancer. There are no evidence-based guidelines for the management of these conditions, which often require drugs that interfere with hemostasis, enhance the bleeding tendency, and warrant more intensive replacement therapy. At the moment, elderly patients with hemophilia affected by other diseases should be managed like their age-group peers without hemophilia, provided replacement therapy is tailored to the heightened risk of bleeding associated with the need for invasive procedures and drugs that further compromise the deranged hemostasis. More detailed advice is provided on the schedules of replacement therapy needed to tackle cardiovascular diseases, such as acute coronary syndromes and nonvalvular atrial fibrillation, because these conditions will become more and more frequent challenges for the comprehensive treatment centers.

Abstract
AIM: To observe the efficacy of octreotide in the treatment of intractable Mallory-Weiss syndrome (MWS).
METHODS: Forty-seven MWS patients who did not respond to routine treatment within 24 h were randomly divided into two groups: treatment group (n = 24) and control group (n = 23). Patients in the control group were given an intravenous infusion of 40 mg omeprazole, once every 12 hours, while those in the treatment group were given the same dose of omeprazole as well as continuous intravenous administration of octreotide via a micro pump at a constant speed of 25 μg/h for three days.
RESULTS: After treatment with octreotide, hemostasis was achieved in 17 (70.8%) patients. The overall response rate achieved in the treatment group was significantly higher than that in the control group (91.67% vs 73.91%, P < 0.01). Moreover, the hemostasis success rate in the treatment group was significantly higher than that in the control group (P < 0.01).
CONCLUSION: Combined use of octerotide and omeprazole is more effective in the treatment of MWS patients who do not respond to routine treatment.
