Hereditary Hemorrhagic Telangiectasia (HHT) is a genetic disorder of angiogenesis associated with disabling epistaxis. Management of these nose bleedings requires more effective treatment. Propranolol, a beta-blocker, is a potentially useful therapeutic considering its anti-angiogenic properties. Our objective is to explore the efficacy of propranolol, three months after its introduction, on the cumulative duration of epistaxis in HHT patients.
This study is a double-blinded, randomized controlled trial to evaluate the efficacy of an intranasal topical timolol gel in the care for epistaxis in adults with hereditary hemorrhagic telangiectasia.
Investigators will test the value of very low dose Pazopanib administered to patients with hereditary hemorrhagic telangiectasia for the reduction in the severity of nose bleeds in those with frequent and long duration bleeding episodes.
Hereditary hemorrhagic telangiectasia (HHT) is associated with recurrent epistaxis in 90% of cases. Good response to hormone treatment has been documented, although its use remains controversial. A double-blind placebo-controlled trial with estrogen treatment did not show any benefit over placebo. The aim of this study is to examine the efficacy of an antiestrogenic agent, TAMOXIFEN, in the treatment of HHT-associated epistaxis. The study will include up to 60 patients, over 18...
OBJECTIVES: I. Evaluate migraine prophylaxis with soy protein isolate in patients with hereditary hemorrhagic telangiectasia. II. Assess whether soy protein isolate reduces the frequency and severity of epistaxis and gastrointestinal bleeding in these patients.
This is a Phase II placebo-controlled double-blind study of pomalidomide in patients with hereditary hemorrhagic telangiectasia (HHT) with moderate to severe epistaxis who require parenteral iron infusions or blood transfusions. A total of 159 patients will be randomized 2:1 to treatment with oral pomalidomide or matching placebo for 24 weeks. Mean change from baseline to 24 weeks in the Epistaxis Severity Score (ESS) will be compared between treatment groups to determine pomal...
This study will investigate the effectiveness of oral doxycycline for the treatment of recurrent nasal hemorrhage in Hereditary Hemorrhagic Telangiectasia (HHT) subjects. The primary outcome for the trials will be the reduction of epistaxis severity (minutes of bleeding per week). The biological outcomes of interest are the regression of vascular malformations as well as tissue and circulation biomarkers of the relevant mechanistic pathways. A Phase II, randomized double-blind ...
Hereditary haemorrhagic telangiectasia (HHT), also known as Rendu-Osler-Weber syndrome, is an inherited multisystemic disorder with recurrent epistaxis, mucocutaneous telangiectasia and visceral arteriovenous malformations. The purpose of this study is to provide data about multiple clinical aspects of HHT and responses to treatment. For comparison of some aspects also data of non-affected relatives is collected (second cohort). the questionnaire has been designed primarily for...
Current management strategies for severe and recurrent epistaxis secondary to Hereditary hemorrhagic telangiectasia (HHT) include surgical procedures, and uncomfortable nasal packing, both of which are often only short-term solutions. Floseal® may provide a non-invasive and less painful treatment option for epistaxis in HHT patients. This hemostatic agent has been shown to be an effective intraoperative hemostatic agent in a number of surgical procedures including endoscopic s...
OBJECTIVES: I. Collect data regarding the natural history of hereditary hemorrhagic telangiectasia (HHT). II. Establish genotype-phenotype correlations in HHT. III. Create a database of information for researchers throughout the world.
The investigators will study whether Pazopanib, taken daily for 6 months, will reduce the severity of nose bleeds in patients with hereditary hemorrhagic telangiectasia. Patients will either be provided drug or a placebo [sugar non-drug pill], and be tested for nose bleed severity throughout the trial, including particularly nose bleed duration. Investigators will also test for blood loss, as well as for safety.
The purpose of this research study is to determine whether Doxycycline can be used to control nosebleeds (epistaxis) for patients with Hereditary Hemorrhagic Telangiectasia (HHT). Patients with HHT will be randomized to one of 2 study arms: Doxycycline or Placebo for a period of 2 months followed by a 1-month washout period before switching treatments for a further 2 months period. Observation and evaluation will continue for a period of one month after treatment is completed.
Liver transplantation (LT) has been proposed as a curative treatment in hereditary hemorrhagic telangiectasia (HHT) with severe hepatic involvement. The investigating team provides a long-term evaluation of graft status after LT for HHT with a focus on the risk of recurrence. The present study included all patients prospectively followed up after LT for HHT in the Lyon Liver Transplant Unit from 1993 to 2010 with a survival of more than 1 year.
OBJECTIVES: I. Examine screening modalities for pulmonary vascular arteriovenous malformation (PAVM) in individuals with endoglin mutations. II. Examine the prevalence of cerebral arteriovenous malformations (CAVM) in individuals with hereditary hemorrhagic telangiectasia (HHT). III. Investigate whether modifier genes exist that determine which individuals with HHT due to an endoglin mutation develop PAVMs and which develop CAVMs. IV. Investigate the frequency of c...
Hereditary hemorrhagic telangiectasia (HHT) results from genetic deregulation of angiogenesis. It is characterized by mucocutaneous telangiectasia responsible for recurrent epistaxis affecting quality of life (anaemia, iron deficiency, social distress). More rarely, HHT is complicated by the appearance of pulmonary, hepatic or cerebral arteriovenous malformations that can lead to serious complications: cerebrovascular accidents, cerebral abscesses, high output heart failure, an...
The purpose of the study is to evaluate the safety and tolerability of pegylated interferon alpha-2b (PEG-Inton) in patients with severe complications related to Hereditary hemorrhagic telangiectasia (HHT).
OBJECTIVES: I. Evaluate the efficacy of octreotide, a somatostatin octapeptide analog, in decreasing gastrointestinal bleeding in patients with hormone-refractory hereditary hemorrhagic telangiectasia or senile ectasia.
Compare the frequency of epistaxis and quality of life related to nasal bleeding in patients with HHT colonized with sataphylococo before and after being treated with mupirocin ointment.
The recognized manifestations of HHT are all due to abnormalities in vascular structure. Epistaxis due to telangiectases formation is spontaneous, very variable, recurrent in 90% of patients, and associated with severe anemia in 2-10%. They also significantly reduce quality of life. Improvement in epistaxis has been shown in HHT patients after a liver transplantation. It was hypothesized that the immunosuppressive treatment (FK506) used to prevent rejection may have an a...
Hereditary haemorrhagic telangiectasia is a disease inherited as an autosomal dominant disease. Analysing DNA from affected and unaffected family members allows us to identify the location of disease genes by linkage analysis. Sequencing genes in the interval identified by linkage analysis allows us to identify which precise gene is mutated. Further functional studies can then determine why the mutations in that gene cause the disease.
The recognized manifestations of HHT are all due to abnormalities in vascular structure. Epistaxis are spontaneous, very variable, may occur as often as several times every day, and are recurrent in 90% of patients and associated with chronic and severe anemia in 2-10%. They also significantly reduce quality of life. Blood transfusions are sometimes required in 10-30% of patients. Previous studies showed that antiangiogenic treatments such as anti-VEGF treatment (bevacizumab) ...
The inherited disease hereditary haemorrhagic telangiectasia (HHT) causes bleeding from dilated fragile vessels, particularly in the nose and gut. However, many HHT patients develop deep venous thromboses and/or pulmonary embolism, necessitating treatments with anticoagulants that further impair control of their haemorrhagic state. Our initial observations using general coagulation tests suggest that the blood of HHT patients is intrinsically hypercoagulable. We hypothes...
Hereditary Haemorrhagic Telangiectasia (HHT, also known as Osler-Weber-Rendu Syndrome) is an disease that leads to the development of dilated and fragile blood vessels. We propose to obtain small skin samples from patients with HHT in order to analyze the samples using histological methods, and study the properties of vascular endothelial cells derived from patients. We hypothesize that these cells will show altered growth, migration, and protein synthetic differences when com...
The goal of this study is to better understand HHT, the symptoms and complications it causes ("outcomes") and how the disease impacts people's lives. The investigators are aiming to recruit and gather information together in the Registry from 1,000 HHT patients from four HHT Centres of Excellence in North America. The Investigators will collect long-term information about the people in the Registry, allowing the investigators to understand how the disease changes over time, and...
Hereditary Haemorrhagic Telangiectasia (HHT, also known as Osler-Weber-Rendu Syndrome) is an disease that leads to the development of dilated and fragile blood vessels. We propose to culture endothelial cells from patients with HHT, to culture cells that express the proteins mutated in HHT, namely endoglin and ALK-1. We will study the properties of these cells which will involve their growth in different conditions and anticipate that DNA, mRNA and proteins will be extracted fr...
