Evaluation of Video-assisted Instructions of Nasal Self-packing in Patients With HHT

Hereditary Haemorrhagic Telangiectasia

Inserting nasal self-packings is a secure method leaving patients more self-confident. We provide a video on https://www.youtube.com/watch?v=LaioLYfSJ-E demonstrating how to use nasal self-packings.

Influence of Hypoxic Induced Factors in Patients With Hereditary Hemorrhagic Telangiectasia

Hereditary Hemorrhagic Telangiectasia

Patients with hereditary hemorrhagic telangiectasia (HHT) suffer from an inherited disorder leading to systemic vascular malformations. Mutations in several genes of the transforming growth factor (TGF)-β superfamily pathway influence angiogenesis in patients with HHT. The genetic loss of ALK1 or ENG alone are not sufficient to induce AVMs; environmental insults that could trigger angiogenesis (e.g. wounding) are also needed. In this study it will be analyzed if hypoxic induced factors could have an influence on the disease HHT.

Evaluation of Pazopanib on Bleeding in Subjects With Hereditary Haemorrhagic Telangiectasia

TelangiectasiaHereditary Hemorrhagic

This study will investigate whether pazopanib can reduce epistaxis and improve anaemia in subjects with hereditary haemorrhagic telangiectasia (HHT) at a dose that is well tolerated. The study will have 2 parts. Part A will be an open label, dose-escalation study in which up to 4 cohorts of approximately 6 subjects each will receive increasing doses of pazopanib for a maximum of 12 weeks. The dose in the first cohort will be 50mg per day and the maximum dose in a cohort will be 400 mg per day. Dose escalation will not occur as planned if the predefined safety stopping criteria are met or at least 4 subjects in a cohort have demonstrated efficacy (as measured by epistaxis, haemoglobin, transfusion or iron infusion requirements). If efficacy is demonstrated in Part A with an acceptable safety profile, Part B will be initiated to further define the optimal dose(s) including dose duration/schedule and to provide further support for the proof of mechanism. Approximately 15 subjects will participate and will be randomised to active or placebo in a ratio of 3:2. This part of the study will be double-blind.

Skin Imaging to Inform Laser Treatments

Port-Wine StainRosacea2 more

The purpose of this study is to obtain information (such as lesion depth, depth of the most superficial part of the lesion, and the size and density of blood vessels) with the assistance of an imaging device, and use this information to assist in selection of laser settings for the treatment of skin conditions. The imaging modality is called Optical Coherence Tomography (OCT). Multiple laser modalities will be used, including intense pulsed light lasers (BroadBand Light, Profractional Sciton), pulsed dye lasers (Vbeam Perfecta, Candela), long-pulse 755nm lasers (GentleLASE, Candela), Sciton long-pulse 1064nm lasers, and non-ablative and ablative fractional resurfacing lasers (Profractional, Sciton). All of the lasers noted above are the only ones that will be used in this study. These lasers have 510k clearance and are being used as per their approved indications in this study. The choice of laser type is based on the skin lesion and is recommended by the physician, and the subjects who are going to enroll in this study will already be planned to undergo laser treatment as a standard of care for their condition. This is a pilot study that will explore the utility of skin imaging in guiding the laser treatment of skin lesions.

Efficacy of a Bevacizumab Nasal Spray as a Treatment for Epistaxis in Hereditary Hemorrhagic Telangiectasia...

Hereditary Hemorrhagic TelangiectasiaEpistaxis

Hereditary Hemorrhagic Telangiectasia (HHT) is a rare (~ 1/6000) but ubiquitous genetic disease. It is associated with abnormal angiogenesis and autosomal dominant inheritance, leading to telangiectasias and arteriovenous fistulae. More than 95% of patients are concerned by epistaxis (nosebleeds). These events are spontaneous, repeated, irregular, both diurnal and nocturnal, a source of anemia, disabling and very socially embarrassing. Anti-angiogenic treatments, including bevacizumab, are a new therapeutic option in HHT. The aim of this study is to evaluate 3 months after the end of the treatment the efficacy on the duration of the nosebleeds with 3 different doses (25, 50 and 75 mg) of bevacizumab administered as a nasal spray in a repeated manner (3 administrations) in patients with Hereditary Hemorrhagic Telangiectasia complicated by nosebleeds. This randomized, double-blind, placebo-controlled, seamless phase II/III study is to be carried out on 4 groups of 20 patients for first step and 2 groups of 20 to 40 patients for second step

Studies of White Blood Cells Derived From HHT Patients

TelangiectasiaHereditary Hemorrhagic

Hereditary Haemorrhagic Telangiectasia (HHT, also known as Osler-Weber-Rendu Syndrome) is an inherited vascular disease that leads to the development of dilated and fragile blood vessels. The study goal is to culture white blood cells that express the proteins mutated in HHT and examine in the laboratory to explain aspects of the HHT disease phenotype.

Iron Deficiency and Hereditary Haemorrhagic Telangiectasia

Hereditary Haemorrhagic Telangiectasia

Managing iron deficiency is important for more than 1 billion individuals worldwide, to avoid blood transfusions, or excessive strain on vital organs that depend on iron-containing haemoglobin to deliver oxygen to the tissues. Iron deficiency is a particular problem for people with the inherited condition hereditary haemorrhagic telangiectasia (HHT). Their iron deficiency and anaemia results from blood losses, especially from the nose (nosebleeds, and they often need additional iron to replace that lost through bleeding. Our goal is to stratify HHT patients into high/low absorbers of iron; to define what extra iron they need to adjust for their current and likely future blood losses; and to work out how to achieve this most safely for each individual to improve their later health. We will test the hypothesis that informed assessment of iron intake and post absorption cellular profiles changes the recommendations for iron intake for HHT patients.
