Filter by:Computed tomography (CT) is the modality of choice to characterize pulmonary arteriovenous malformations (PAVMs) in patients with hereditary haemorrhagic telangiectasia (HHT). The objective of this study was to determine if CT findings were associated with frequency of brain abscess and ischaemic stroke. This retrospective study included patients with HHT-related PAVMs. CT results, PAVM presentation (unique, multiple, disseminated or diffuse), the number of PAVMs and the largest feeding artery size, were correlated to prevalence of ischaemic stroke and brain abscess.
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 have anemia and/or 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 pomalidomide efficacy.
Hereditary Haemorrhagic Telangiectasia (HHT) is a rare inherited genetic disease of autosomal dominant inheritance with a prevalence of 1/6000. It is manifested by haemorrhages, mucocutaneous telangiectasias and visceral arteriovenous malformations. These symptoms significantly affect the daily lives of patients, their social relationships and their working lives. HAS (Haute Autorité de Santé) national recommendations focus on assessing and improving the quality of life (QOL) of patients. Many scales for measuring QOL exist but they are most often general and therefore have the disadvantage of not taking into account the particularities of pathologies and their symptoms and do not allow to have a precise vision of their impact on QOL. It is important to be able to evaluate this impact, to determine its nature and to quantify it so that health professional can adapt their proposal for the management of HHT patients. And only the development of a specific and validated QOL measurement scale will allow them to access this information. The aim of this study is to develop a scale of measurement of quality of life in HHT disease and to validate it, a scale specific to HHT, simple and fast to fill by the patients themselves.
Hereditary Haemorrhagic Telangiectasia (HHT) is a rare inherited genetic disease of autosomal dominant inheritance with a prevalence of about 1/5000. It is manifested by haemorrhage, mucocutaneous telangiectasia and visceral arteriovenous malformations (AVMs) (lung, liver and nervous system). Severe complications during pregnancy in HHT are rare but considered high risk. Intracranial or pulmonary haemorrhage, stroke and heart failure have been reported in some women with HHT during pregnancy. These complications occur most often in the second and third trimesters when maternal physiological changes such as peripheral vasodilatation and increased cardiac output are at their peak. Previous retrospective studies were conducted with numbers ranging from 40 to 97 patients and highlighted the importance of early screening of complications and specific management. The aim of this study is to describe, on a larger number of patients, the obstetric and neonatal complications in patients with HHT and followed in the French Reference Center for HHT.
This study is conducted to evaluate the safety of THR-317 when administered intravitreally and to assess the compound's efficacy in reducing central subfield thickness (CST) and improving best-corrected visual acuity (BCVA) in subjects with macular telangiectasia Type 1 (MacTel 1).
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, and massive hemoptysis (1). The intensity of symptoms increases with age but with significant individual variability, even for the same mutation in the same family. Thus, while the mutations responsible for the disease have been identified, the pathophysiology is not fully understood because these mutations do not explain the great diversity of clinical presentations. Other factors not yet identified probably play an important role. Angiogenic T cells (TANG) are a newly individualized T cell population, defined by a CD4+CXCR4+CD31+ phenotype, which plays a key role in differentiating endothelial progenitors (2). In an earlier study, the investigators showed that patients with HHT had a decrease in CD4+ and CD8+ LT compared to a cohort of healthy subjects (3). They hypothesize that the lymphopenia mainly involves TANG, whose quantification could make it possible to assess the individual level of angiogenesis during HHT. The evaluation of the TANG levels could thus make it possible to personalize HHT management.
The goal is to compare a novel yellow laser, based on semiconductor technology, with traditional green laser, in the treatment of cheek telangiectasias. The trial design is randomized split-face double-blinded study with 20-30 volunteers. The improvement will be assessed using a 7-point Telangiectasia Grading Scale.
This is a two armed Single Masked Pilot Study enrolling participants with Macular Telangiectasia Type 2 who will be randomized to undergo either a subthreshold photothermal treatment or a sham procedure to one eye. The participants will be followed for one year with visits at 1 month, 3 months, 6 months and 12 months post-treatment (laser or sham). Due to the small number of participants enrolled in this study the data will be analyzed by descriptive statistics and exploratory figures. Summary statistics will be produced for study and fellow eyes.
This study is a phase 3, randomized, multi-center study to evaluate the efficacy and safety of the NT-501 implants in participants with macular telangiectasia type 2.
