Hereditary Haemorrhagic Telangiectasia (HHT) is as an autosomal dominant trait characterized by frequent nose bleeds, mucocutaneous telangiectases, arteriovenous malformations (AVMs) of the lung, liver and brain, and gastrointestinal bleedings due to telangiectases. HHT is originated by mutations in genes whose encoded proteins are involved in the transforming growth factor β (TGF-β) family signalling of vascular endothelial cells. In spite of the great advances in the diagnosis as well as in the molecular, cellular and animal models of HHT, the current treatments remain just at the palliative level...

t Hereditary Hemorrhagic Telangiectasia (HHT), also known as Osler-Weber-Rendu Disease, is an autosomal dominant genetic disorder that is characterized by the abnormal development of blood vessels. While the pathophysiology underlying the development of pulmonary hypertension (PH) in patients with HHT is not fully understood, it is believed to occur by one of two mechanisms: increases in pulmonary vascular resistance or cardiac output. In the following report, we describe an interesting case of a 26-year-old woman with HHT whose right heart catheterization initially demonstrated PH with elements of both pre- and post-capillary PH...

Hepatopulmonary syndrome (HPS) is a severe complication of advanced liver disease associated with an extremely poor prognosis. HPS is diagnosed in 4-47% of patients with cirrhosis and in 15-20% of candidates for liver transplantation. In addition, severe hypoxia is associated with a high risk of complications of liver transplantation (a 30% chance during the first 90 days) and increases the gap between transplantation and improving arterial oxygenation. The pathogenesis of HPS is not fully understood, and no effective pharmacological treatment has been developed yet...

BACKGROUND AND PURPOSE: There is a high prevalence of right-to-left shunting pulmonary arteriovenous malformations (PAVMs), which are stroke risk factors, in hereditary hemorrhagic telangiectasia (HHT) patients. While the prevalence of ischemic complications in HHT patients is known, the prevalence of silent brain infarcts (SBI) remains unknown. The purpose of this study was to determine the prevalence and risk factors for SBI in HHT patients. MATERIALS AND METHODS: Our institutional HHT database was queried to identify HHT patients who received a baseline screening brain MRI from January 2000 to February 2017...

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is a vascular disorder characterized by arteriovenous malformations in the brain, liver, and lungs. Pulmonary hypertension (PH) is increasingly recognized as a severe complication of HHT. However, there are no studies describing the prevalence of PH in HHT compared to HHT-negative controls. OBJECTIVE: To assess the estimated prevalence of PH in patients with HHT compared to HHT-negative controls. METHODS: All consecutive subjects screened for HHT with available genetic testing and echocardiography-based peak tricuspid regurgitation velocity (TRV) measurement were included...

BACKGROUND: Massive pulmonary emboli can cause an abrupt onset of symptoms simultaneous with large pulmonary artery occlusions. In contrast, the temporal relationship between pulmonary vascular occlusion by smaller emboli and the development of symptoms of pulmonary infarction is unknown. We describe the time interval between embolization and the onset of clinical symptoms and signs compatible with pulmonary infarction. METHODS: We examined the records of 56 patients with hereditary hemorrhagic telangiectasia (HHT) who underwent therapeutic balloon embolization of pulmonary arteriovenous malformation (PAVM) in a single center after noting that some of them experienced symptoms and signs compatible with pulmonary infarction...

Background -Most AVMs are localized and occur sporadically; however they also can be multifocal in autosomal dominant disorders, such as Hereditary Hemorrhagic Telangiectasia (HHT) and Capillary Malformation-Arteriovenous Malformation (CM-AVM). Previously, we identified RASA1 mutations in 50% of patients with CM-AVM. Herein we studied non-RASA1 patients to further elucidate the pathogenicity of CMs and AVMs. Methods -We conducted a genome-wide linkage study on a CM-AVM family. Whole exome sequencing was also performed on 9 unrelated CM-AVM families...

Intranasal bevacizumab injections have been used in treating hereditary hemorrhagic telangiectasia (HHT)-related epistaxis since 2009. It is believed to be a safe and effective treatment for a selected group of HHT patients in reducing frequency and intensity of epistaxis, with few or none adverse effects. In this case report, however, we will describe a patient who developed bilateral osteonecrosis in the knees while undergoing regular intranasal submucosal bevacizumab injections. Although osteonecrosis previously has been documented in patients receiving bevacizumab intravenously in oncologic doses, thus far it has not been reported in patients treated with intranasal submucosal injections...

A 70-year-old patient with known hereditary haemorrhagictelangiectasia (HHT) was seen regularly in our outpatient clinic. He underwent multiple therapeutical interventions, including both surgical and medical, for the treatment of recurrent epistaxis without sustained success. Due to a concurrent diagnosis of idiopathic pulmonary fibrosis, treatment with the tyrosine kinase inhibitor nintedanib was initiated, after which point the patient reported a dramatic and unanticipated improvement in his epistaxis and skin telangiectasia...

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is a rare genetic disorder known for its debilitating symptoms. More than 90% of patients with HHT experience epistaxis, and they average up to 18 bleeds per month. We review the current literature on the pathophysiology, clinical presentation, and management of HHT. METHODS: We searched MEDLINE, EMBASE, and PubMed and identified 19 articles published since 2000 with current information on HHT. RESULTS: HHT is a disease more commonly associated with significant morbidity rather than mortality...

Intravenous bevacizumab decreased mucosal bleeding in some patients with hereditary hemorrhagic telangiectasia (HHT). We treated a 47-year-old male who had HHT, severe epistaxis, and gastrointestinal bleeding, alcoholic cirrhosis, and portal hypertension with intravenous bevacizumab 2.5 mg/kg every 2 weeks. We tabulated these measures weekly during weeks 1-33 (no bevacizumab); 34-57 (bevacizumab); and 58-97 (no bevacizumab): hemoglobin (Hb) levels; platelet counts; units of transfused packed erythrocytes (PRBC units); and quantities of iron infused as iron dextran to support erythropoiesis...

BACKGROUND: Children with Hereditary Hemorrhagic Telangiectasia (HHT) may have pulmonary arteriovenous malformations (AVMs), which can lead to symptoms of shortness of breath, exercise intolerance, clubbing, cyanosis and hemoptysis. However, some patients with pulmonary AVMs may be asymptomatic, placing them at risk for complications such as stroke or brain abscess if they are not identified and treated. This study examines the incidence of signs and symptoms associated with pulmonary AVMs in children with HHT known to have pulmonary AVMs...

REVIEW
Omar Bari, Philip R Cohen
Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant condition with a prevalence of ~1 in 5,000 individuals. The pathophysiology of this condition centers on the lack of capillary beds between arterioles and venules, leading to direct contact between these vessels. This results in telangiectases on characteristic locations such as the face, fingers, mouth, and nasal mucosa. Visceral arteriovenous malformations (AVMs) are also observed in many patients, and these are most commonly seen in the brain, gastrointestinal tract, and lungs...
