Hereditary Hemorrhagic Telangiectasia (HHT) and Survival: The Importance of Systematic Screening and Treatment in HHT Centers of Excellence.

Els M de Gussem, Steven Kroon, Anna E Hosman, Johannes C Kelder, Martijn C Post, Repke J Snijder, Johannes J Mager,

Hereditary hemorrhagic telangiectasia (HHT), an autosomal dominant disease, is characterized by telangiectases and arteriovenous malformations (AVMs). Untreated AVMs, especially in the lungs-pulmonary AVMs (PAVMs)-can result in morbidity with a decreased life expectancy. We have investigated whether HHT patients, systematically screened for HHT-related organ involvement and treated if needed, have a ... Read more >>

The use of echo density to quantify pulmonary right-to-left shunt in transthoracic contrast echocardiography.

Steven Kroon, Mitch C J Van Thor, Veerle M M Vorselaars, Anna E Hosman, Martin J Swaans, Repke J Snijder, Hans-Jurgen Mager, Marco C Post,

<h4>Aims</h4>Transthoracic contrast echocardiography (TTCE) is the recommended screening tool to detect pulmonary right-to-left shunt (RLS) caused by pulmonary arteriovenous malformations (PAVMs). We assessed a novel method to quantify the RLS using the change in echo density (ED) following contrast injection.<h4>Methods and results</h4>An analysis of 437 consecutive patients [58% female, 47 years, ...

Prevalence and diagnostic value of nail fold capillary microscopy in hereditary hemorrhagic telangiectasia: A retrospective study.

Steven Kroon, Veronique Mm Vorselaars, Anna E Hosman, Martijn C Post, Repke J Snijder, Johannes J Mager,

Abnormal vasculature is a key feature of hereditary hemorrhagic telangiectasia (HHT) and can also present in the nail fold capillary beds. However, the exact prevalence and the clinical diagnostic value in HHT are still largely unknown. The nail fold can be easily and noninvasively inspected with a capillary microscope. We ...

Decreased Expression of Vascular Endothelial Growth Factor Receptor 1 Contributes to the Pathogenesis of Hereditary Hemorrhagic Telangiectasia Type 2.

Jérémy H Thalgott, Damien Dos-Santos-Luis, Anna E Hosman, Sabrina Martin, Noël Lamandé, Diane Bracquart, Samly Srun, Georgios Galaris, Hetty C de Boer, Simon Tual-Chalot, Steven Kroon, Helen M Arthur, Yihai Cao, Repke J Snijder, Frans Disch, Johannes J Mager, Ton J Rabelink, Christine L Mummery, Karine Raymond, Franck Lebrin,

<h4>Background</h4>Hereditary Hemorrhagic Telangiectasia type 2 (HHT2) is an inherited genetic disorder characterized by vascular malformations and hemorrhage. HHT2 results from ACVRL1 haploinsufficiency, the remaining wild-type allele being unable to contribute sufficient protein to sustain endothelial cell function. Blood vessels function normally but are prone to respond to angiogenic stimuli, leading ... Read more >>

Pulmonary Arterial Hypertension and Hereditary Haemorrhagic Telangiectasia.

Veronique M M Vorselaars, Anna E Hosman, Cornelis J J Westermann, Repke J Snijder, Johannes J Mager, Marie-Jose Goumans, Marco C Post,

Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant inherited disease characterised by multisystemic vascular dysplasia. Heritable pulmonary arterial hypertension (HPAH) is a rare but severe complication of HHT. Both diseases can be the result of genetic mutations in <i>ACVLR1</i> and <i>ENG</i> encoding for proteins involved in the transforming growth factor-beta ... Read more >>

Executive summary of the 12th HHT international scientific conference.

Jillian W Andrejecsk, Anna E Hosman, Luisa M Botella, Claire L Shovlin, Helen M Arthur, Sophie Dupuis-Girod, Elisabetta Buscarini, Christopher C W Hughes, Franck Lebrin, Christine L Mummery, Marco C Post, Johannes J Mager,

Hereditary hemorrhagic telangiectasia is an autosomal dominant trait affecting approximately 1 in 5000 people. A pathogenic DNA sequence variant in the ENG, ACVRL1 or SMAD4 genes, can be found in the majority of patients. The 12th International Scientific HHT Conference was held on June 8-11, 2017 in Dubrovnik, Croatia to ... Read more >>

Screening children for pulmonary arteriovenous malformations: Evaluation of 18 years of experience.

Anna E Hosman, Els M de Gussem, Walter A F Balemans, Andréanne Gauthier, Cees J J Westermann, Repke J Snijder, Marco C Post, Johannes J Mager,

<h4>Background</h4>Hereditary Hemorrhagic Telangiectasia (HHT) is an autosomal dominant disease with multi-systemic vascular dysplasia. Early diagnosis through screening is important to prevent serious complications. How best to screen children of affected parents for pulmonary arteriovenous malformations (PAVMs) is often subject to debate. Transthoracic contrast echocardiogram (TTCE) is considered optimal in screening ... Read more >>

Specific cancer rates may differ in patients with hereditary haemorrhagic telangiectasia compared to controls.

Anna E Hosman, Hannah L Devlin, B Maneesha Silva, Claire L Shovlin,

<h4>Background</h4>Hereditary haemorrhagic telangiectasia (HHT) is inherited as an autosomal dominant trait, affects ~1 in 5,000, and causes multi-systemic vascular lesions and life-limiting complications. Life expectancy is surprisingly good, particularly for patients over 60ys. We hypothesised that individuals with HHT may be protected against life-limiting cancers.<h4>Methods</h4>To compare specific cancer rates in ... Read more >>

Lifestyle and dietary influences on nosebleed severity in hereditary hemorrhagic telangiectasia.

B Maneesha Silva, Anna E Hosman, Hannah L Devlin, Claire L Shovlin,

<h4>Objectives/hypothesis</h4>To identify factors influencing the severity of epistaxis in hereditary hemorrhagic telangiectasia (HHT).<h4>Study design</h4>Participants with and without HHT were recruited from a specialist service and online following advertisement by the HHT Foundation International. Both groups were asked to complete a nonbiased questionnaire.<h4>Methods</h4>The reported effects of specific treatments or lifestyle factors ... Read more >>
