Abstract
Extracranial arteriovenous malformations (AVMs) are regarded as rare diseases and are prone to complications such as pain, bleeding, relentless growth, and high volume of shunted blood. Due to the high vascular pressure endothelial cells of AVMs are exposed to mechanical stress. To control symptoms and lesion growth pharmacological treatment strategies are urgently needed in addition to surgery and interventional radiology. AVM cells were isolated from three patients and exposed to cyclic mechanical stretching for 24 h. Thalidomide and bevacizumab, both VEGF inhibitors, were tested for their ability to prevent the formation of circular networks and proliferation of CD31+ endothelial AVM cells. Furthermore, the effect of thalidomide and bevacizumab on stretched endothelial AVM cells was evaluated. In response to mechanical stress, VEGF gene and protein expression increased in patient AVM endothelial cells. Thalidomide and bevacizumab reduced endothelial AVM cell proliferation. Bevacizumab inhibited circular network formation of endothelial AVM cells and lowered VEGF gene and protein expression, even though the cells were exposed to mechanical stress. With promising in vitro results, bevacizumab was used to treat three patients with unresectable AVMs or to prevent regrowth after incomplete resection. Bevacizumab controlled bleeding, pulsation, and pain over the follow up of eight months with no patient-reported side effects. Overall, mechanical stress increases VEGF expression in the microenvironment of AVM cells. The monoclonal VEGF antibody bevacizumab alleviates this effect, prevents circular network formation and proliferation of AVM endothelial cells in vitro. The clinical application of bevacizumab in AVM treatment demonstrates effective symptom control with no side effects.

Abstract
BACKGROUND Studies evaluating health-related quality of life (HRQOL) in patients with hereditary hemorrhagic telangiectasia (HHT) have expanded rapidly in the past decade. These studies have evaluated QOL aspects ranging from the general QOL for patients living with HHT to intervention-specific outcomes. However, few tools have been fully validated across the spectrum of disease manifestations and interventions in HHT. OBJECTIVE In this scoping review, we aim to map the literature on HHT-QOL metrics, identify gaps, inform future QOL research, and facilitate future metric development. METHODS We analyzed articles in English that assessed at least 1 measure of general HRQOL, including physical health, mental health, social health, or intervention-specific QOL in patients with HHT. Searches across 2 bibliographic databases (PubMed and Scopus) yielded 186 articles after duplicates were removed. Sixty-three studies met eligibility criteria: 22 prospective studies (34.9%), 20 retrospective studies (31.7%), 12 cross-sectional studies (17.5%), 6 randomized controlled trials or secondary analyses of a randomized controlled trials (9.5%), 2 qualitative studies (3.2%), and 1 case-control study (1.6%). Two additional studies-1 prospective and 1 cross-sectional study-were identified at the October 2022 14th International HHT Conference and included, making a total of 65 studies. RESULTS The 65 eligible studies used 30 QOL instruments. Twenty studies characterized baseline HRQOL, and 45 studies evaluated QOL before and after treatment. Of those 45 studies, 37 evaluated HRQOL before and after therapies targeting epistaxis and nasal symptoms, 4 targeted therapies for liver arteriovenous malformations and high-output heart failure, 3 evaluated therapies for both epistaxis and gastrointestinal bleeding, and 1 evaluated treatment targeting gastrointestinal bleeding alone. CONCLUSIONS Comparison of results across studies remains challenging given the heterogeneity in outcomes measures. Further development of HHT-specific patient-reported outcomes instruments that capture the global illness experience of HHT is needed.

Abstract
Hereditary hemorrhagic telangiectasia (HHT) type 2 is an autosomal dominant disease in which one allele of the ACVRL1 gene is mutated. Patients exhibit disturbances in TGF-beta/BMP-dependent angiogenesis and, clinically, often present with severe nosebleeds as well as a reduced quality of life. The aim of our study was to use CRISPR/Cas9 to knockout ACVRL1 in normal induced pluripotent stem cells (iPSCs) and evaluate the effects on TGF-beta- and BMP-related gene expression as well as angiogenesis. The CRISPR/Cas9 knockout of the ACVRL1 gene was carried out in previously characterized wild-type (ACVRL1wt/wt) iPSCs. An HHT type 2 iPS cell line was generated via a single-allele knockout (ACVRL1wt/mut) in wild-type (ACVRL1wt/wt) iPSCs, resulting in a heterozygous 17 bp frameshift deletion in the ACVRL1 gene [NG_009549.1:g.13707_13723del; NM_000020.3:c.1137_1153del]. After the generation of embryoid bodies (EBs), endothelial differentiation was induced via adding 4 ng/mL BMP4, 2% B27, and 10 ng/mL VEGF. Endothelial differentiation was monitored via immunocytochemistry. An analysis of 151 TGF-beta/BMP-related genes was performed via RT-qPCR through the use of mRNA derived from single iPS cell cultures as well as endothelial cells derived from EBs after endothelial differentiation. Differential TGF-beta/BMP gene expression was observed between ACVRL1wt/wt and ACVRL1wt/mut iPSCs as well as endothelial cells. EBs derived from CRISPR/Cas9-designed ACVRL1 mutant HHT type 2 iPSCs, together with their isogenic wild-type iPSC counterparts, can serve as valuable resources for HHT type 2 in vitro studies.

Abstract
Background Vascular malformations in hereditary hemorrhagic telangiectasia (HHT) lead to chronic recurrent bleeding, hemorrhage, stroke, heart failure, and liver disease. There is great interest in identifying novel therapies for epistaxis in HHT given its associated morbidity and impact on quality of life. We aimed to measure the effectiveness of oral doxycycline for the treatment of epistaxis and explore mechanisms of action on angiogenic, inflammatory and pathway markers in HHT using a randomized controlled trial. Methods 13 HHT patients with epistaxis were recruited from the Toronto HHT Center at St. Michael’s Hospital. Recruitment was stopped early due to COVID-19-related limitations. The study duration was 24 months. Patients were randomly assigned to the treatment-first or placebo-first study arm. We compared the change in weekly epistaxis duration and frequency, biomarkers, blood measurements, and intravenous iron infusion and blood transfusion requirements between treatment and placebo. Results There was no significant difference in the change in weekly epistaxis duration (p = 0.136) or frequency (p = 0.261) between treatment and placebo. There was no significant difference in the levels of MMP-9, VEGF, ANG-2, IL-6 or ENG with treatment. Hemoglobin levels were significantly higher (p = 0.0499) during treatment. Ferritin levels were not significantly different between treatment and placebo. There was no significant difference in RBC transfusions between treatment periods (p = 0.299). Conclusion Overall, our study did not demonstrate effectiveness of doxycycline as a treatment for epistaxis in patients with HHT, though the study was underpowered. Secondary analyses provided new observations which may help guide future trials in HHT. Trial Registration ClinicalTrials.gov, NCT03397004.

Abstract
Previous studies have demonstrated that vascular endothelial growth factor (VEGF) is upregulated in patients with hereditary hemorrhagic telangiectasia (HHT). The use of Bevacizumab as an anti-angiogenic treatment agent seems promising. The purpose of the present in vitro study was to determine the efficacy and potential toxicity levels of bevacizumab on cell proliferation and VEGF concentrations in endothelial cells of HHT patients. In this in vitro study, endothelial cells from patients with HHT and HUVECs (control) were incubated with different concentration levels of bevacizumab (2, 4, 6, 8 or 10 mg/ml). After 24, 48 or 72 h, the cell proliferation was assessed by Alamar Blue® Assay and the VEGF levels in the cell culture supernatants were measured by VEGF-ELISA. All endothelial cells incubated with bevacizumab showed an initial decrease in cell proliferation. Cell proliferation recovered within 72 h in cell cultures incubated with concentration levels of up to 4 mg/ml bevacizumab, whereas those incubated with higher concentration levels showed a continuous decline in cell proliferation. VEGF expression decreased after 24 h in cell cultures incubated with bevacizumab concentration levels of 2 and 4 mg/ml but increased again after 48 h. Cell cultures incubated with bevacizumab concentration levels of 10 mg/ml showed a constant decline in VEGF expression without any tendency for recovery. Translating these results into daily clinical practice, the present study suggests that the intranasal submucosal injection of bevacizumab in HHT patients should not exceed a concentration level of 4 mg/ml. Overall, higher bevacizumab concentration levels not only reduce VEGF expression but pose a higher risk of toxic effects on endothelial cells as they jeopardize cell proliferation.

Abstract
INTRODUCTION Given its role in the disease pathophysiology, inhibition of VEGF-mediated angiogenesis has received attention as a potential strategy to reduce epistaxis associated with hereditary hemorrhagic telangiectasia (HHT). This study evaluates the efficacy of a submucosal injection of bevacizumab, a VEGF-inhibitor, in reducing the severity of epistaxis and improving quality of life when given at the time of operative electrocautery. METHODS This randomized, double-blinded placebo-controlled trial was conducted at a single institution from 2014 to 2019. Patients scheduled to undergo operative bipolar electrocautery of nasal telangiectasias were randomized to receive a submucosal injection of saline or bevacizumab at time of surgery. Surveys to assess epistaxis severity and quality-of-life (QOL), including the Epistaxis Severity Score (ESS) and Short Form 12 (SF-12), were administered preoperatively and at 1, 2, 4, and 6 months postoperatively. The minimal clinically important difference (MCID) of the ESS instrument is reported to be 0.71. RESULTS Of 39 patients enrolled, 37 (94.9%) completed the study. The saline group demonstrated reduced ESS versus baseline at 1 (-1.2, p = 0.01) and 4 (-1.2, p = 0.05) months post-procedure. The bevacizumab group demonstrated reduced ESS versus baseline at 1 (-2.3, p<0.001), 2 (-2.3, p<0.001), 4 (-2.0, p = 0.003), and 6 (-1.3, p = 0.05) months post-procedure. The additive benefit of bevacizumab over saline exceeded the MCID at 1, 2, and 4 months but the difference was not statistically significant. CONCLUSION The addition of a single treatment of submucosal bevacizumab may be associated with additional clinically meaningful benefit for up to 4 months when compared to electrocautery alone.

Abstract
Hereditary hemorrhagic telangiectasia (HHT; Rendu-Osler-Weber syndrome) affects the capillary and larger vessels, leading to arteriovenous shunts. Epistaxis is the main symptom impairing quality of life. The aim of the Osler Calendar is to offer information about the extent of the systemic disease and the current state of treatment. A care plan with information on the rare disease and self-treatment of epistaxis was created. Organ examinations and ongoing treatments were recorded. A questionnaire documents the treatment success, including patient satisfaction, frequency of hemorrhage and hemoglobin levels. The patients using the Osler Calendar for at least one year (n = 54) were surveyed. Eighty-five percent of patients (n = 46) used the calendar to gain information about HHT. Seventy-two percent (n = 39) used the Osler Calendar for instructions on the self-treatment of nosebleeds. The calendar increased patients’ understanding for the need for organ screenings from 48% (n = 26) to 81% (n = 44). Seventy-nine percent (n = 43) of patients confirmed that the Osler Calendar documented their therapeutic process either well or very well. Fifty-two percent (n = 28) saw an improvement in the therapeutic process due to the documentation. The Osler Calendar records the individual intensity of the disease and facilitates the communication between attending physicians. It is a tool for specialists to review treatment strategies. Furthermore, the calendar enhances patients’ comprehension of their condition.

Abstract
Hereditary hemorrhagic telangiectasia (HHT; Osler-Weber-Rendu syndrome; Morbus Osler) represents a syndrome affecting capillary vessels, leading to arteriovenous shunting. With an average worldwide prevalence of 1:5.000-8.000 HHT is considered an orphan disease. Arteriovenous shunts involve predominantly the nasal mucosa, the intestine, lung, liver and central nervous system. Epistaxis is the primary and most bothersome complaint of patients with HHT. A multistage therapeutic concept includes nasal ointment, laser therapy under local anesthesia and surgery under general anesthesia, as well as drug therapies. In addition, screening to determine affection of internal organs is carried out. Lesions that require therapy should be treated in an interdisciplinary setting. Treatment of lesions of the skin, oral and gastrointestinal mucosa and liver is carried out in regard to patients' symptoms, whereas vascular malformations of the lung and brain might need treatment without being symptomatic, due to possible life-threatening complications.

[PMID: 31566760 DOI: 10.1002/lary.27889] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2018] [Revised: 11/27/2018] [Accepted: 12/03/2018] [Indexed: 11/12/2022]
Abstract
OBJECTIVES/HYPOTHESIS The objective of this study was to report for the first time on the results of submucosal injections of bevacizumab used in conjunction with cyanoacrylate glue sclerotherapy in hereditary hemorrhagic telangiectasia (HHT). STUDY DESIGN Retrospective analytic chart review. METHODS We performed a chart review that included all patients with HHT treated with intranasal bevacizumab and cyanoacrylate glue for refractory epistaxis at Lariboisiere University Hospital from 2013 with a minimum follow-up of 6 months. We injected 100 mg (25 mg/mL) of bevacizumab diluted in 2 mL of serum at the base of the telangiectasias, and sclerotherapy with an injection of cyanoacrylate glue was used adjunctively. Treatment efficacy was based on changes in Epistaxis Severity Scores (ESS) and the Bergler-Sadick Scale. Quality of life and patient satisfaction were evaluated using the Cantril Self-Anchoring Ladder (CL) and Likert scale, respectively. RESULTS Thirty-one patients were included, with a mean follow-up of 26.6 months. The average ESS score significantly decreased from 7.82 to 3.89 (P < .05). The Bergler-Sadick score significantly improved (P < .05) following the treatment, including the frequency (from 2.74 to 1.64) and the quantity (from 2.54 to 1.51) scales. Quality of life was significantly improved (P < .05) using the CL score (from 4.16 to 7.22). The Likert satisfaction scale related to the treatment efficacy was high, with an average of 7.03 out of 10. No complications were noted. CONCLUSIONS Submucosal injections of bevacizumab in conjunction with cyanoacrylate glue sclerotherapy significantly reduced epistaxis and improved the quality of life in HHT. Prospective comparative studies are needed to further evaluate the significance of this treatment modality. LEVEL OF EVIDENCE 3b Laryngoscope, 129:2210-2215, 2019.

Abstract
Introduction Nasal polyposis (NP) is a frequent problem during adulthood. Treatment of NP is primarily based on drugs, such as oral or topical steroids and in some types, by surgery. Despite of available therapeutic options for NP, recurrence after polypectomy is found. Vascular endothelial growth factor (VEGF) is a known factor involved in NP. Bevacizumab is a monoclonal antibody, which acts against VEGF. Aim Regarding the availability of bevacizumab and its use in ophthalmic off-label application, in this study, we hypothesized that it could be a choice of non-invasive treatment. The researchers aimed at evaluating the use of bevacizumab in vitro on the growth of NP. Materials and methods In this experimental study, the researchers used eight non-allergic NP tissues from patients admitted for polypectomy clinic of Imam Reza Hospital, Mashhad. Tissues were cultured in DMEM medium based on standard protocols in the presence or absence of bevacizumab (10 to 250 μM) then incubated. The mean of the responses was reported. The level of VEGF and MTT test for NP epithelial cell viability were determined for each group. Data were analyzed using the SPSS software. Results The researchers demonstrated that bevacizumab leads to a decrease in the level of VEGF (the most common cause of angiogenesis in NP) in media culture of NP, dose-dependently (P<0.001). The highest mean was related to the 10-μM group and the least mean was related to the 250-μM group. In MTT test after 5 days, it was shown that the percentage of viable epithelial NP cells (due to apoptosis) was decreased dose-dependently and could lead to resolving NP tissue (P<0.001), significantly. Conclusion This study showed that bevacizumab could help decrease the growth of NP tissue dose-dependently in organ culture in vitro by inhibiting VEGF. It seems that bevacizumab could be a good candidate for the treatment of non-allergic NP.

Abstract
OBJECTIVES Epistaxis is the most frequent clinical manifestation of hereditary hemorrhagic telangiectasia (HHT). Several topical, systemic, and surgical treatments have been tried, but none have been completely effective. The aim of the present study is to evaluate whether a combined treatment sclerotherapy and topical therapy with propranolol 0.5% nasal formulation would reduce the epistaxis due to HHT and improve patient's quality of life. METHODS An observational cross-sectional study was carried out. The primary outcome measure was frequency and severity of epistaxis as measured by the epistaxis severity score (ESS) at baseline (4 weeks before therapy) and at least 4 weeks after the treatment was implemented. Quality of life was analyzed using EuroQol-5D (EQ-5D) scale and visual analogue (VAS) scale before and after treatment. RESULTS A total of 38 consecutive patients subjected to the combined treatment were evaluated (mean age: 57.2 years, standard deviation [SD] = 13.9; 60.5% women). The mean time of treatment was 37.1 weeks (SD = 14.9). Combined therapy significantly reduces frequency and severity of epistaxis, with an ESS improvement of 5 points from 6.9 ± 2.6 to 1.9 ± 1.3 (P < 0.05); however, the EQ-5D scale increased from 0.66 ± 0.27 to 0.93 ± 0.12 (P < 0.05). The difference in VAS means showed an increase from 44.6 ± 28.3 to 82.5 ± 12.5 (P < 0.05). The increases in quality of life are in line with the drop in ESS. CONCLUSION The study demonstrated that combined therapy (sclerotherapy and topical nasal propranolol) significantly reduced the epistaxis due to HHT and increased patients' quality of life.

Abstract
Hereditary hemorrhagic telangiectasia (HHT) describes the presenting manifestations of a disorder that is characterized by pathologic blood vessels. HHT is inherited as an autosomal dominant trait with variable penetrance. The abnormal vascular structures (dysplasias) can affect all the organs in the human body. The link between a physical stimulus and new lesion development has been established for mucosal trauma owing to nasal airflow turbulence, for ultraviolet exposure to the fingers, and for mechanical trauma to the dominant hand. The pressing question then is whether HHT treatment constitutes a stimulus that is sufficient to trigger new lesion development.

Abstract
Objective Epistaxis is a primary complaint in 90% to 96% of patients with hereditary hemorrhagic telangiectasia (HHT). Numerous surgical and medical treatments aim to decrease the frequency and severity of epistaxis in this patient population. Bevacizumab is a recombinant, humanized monoclonal antibody to vascular endothelial growth factor, an angiogenic factor elevated in HHT. It has been used in several forms to treat epistaxis in HHT but thus far, evidence-based recommendations are limited. Study Design Systematic review with evidence-based recommendations. Methods A systematic review of the literature following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed using Embase, MEDLINE, MEDLINE In-Process/Epub, and Cochrane databases. English language abstracts were reviewed for relevance. Results Eleven manuscripts met inclusion criteria and were analyzed. Submucosal injection, submucosal injection plus laser coagulation, intravenous (IV), and topical formulations of bevacizumab were evaluated for their therapeutic impact on epistaxis in patients with HHT. Three randomized controlled trials failed to show topical bevacizumab to be more effective in controlling epistaxis than saline or other moisturizers. Conclusions The use of submucosal and IV bevacizumab shows promise, but further study is necessary to determine the true efficacy in the treatment of epistaxis as only grade C level exists currently. Based on the available literature, the use of topical bevacizumab is not recommended (grade B).

Abstract
OBJECTIVE To present a multiyear clinical experience with intravenous bevacizumab for the management of severe gastrointestinal bleeding and/or epistaxis in patients with hereditary hemorrhagic telangiectasia (HHT). PATIENTS AND METHODS All patients treated with intravenous bevacizumab for severe hereditary hemorrhagic telangiectasia-related bleeding from June 1, 2013, through January 31, 2017, were included in this report. Severity of epistaxis (determined using the Epistaxis Severity Score questionnaire); hemoglobin, iron, and ferritin levels; and quality of life data were collected serially in all patients. RESULTS Intravenous bevacizumab was administered to 34 patients using a standardized treatment protocol. Anemia was primarily related to severe epistaxis (n=15, 44%), severe gastrointestinal bleeding (n=4, 12%), or both (n=15, 44%), with a median baseline hemoglobin level of 9.1 g/dL (range, 8.3-10.5 gm/dL; to convert to mmol/L, multiply by 0.62). Red blood cell (RBC) transfusions had been administered to 28 patients (82%). Of these, 16 patients (47%) were RBC transfusion dependent and had received a median of 75 RBC transfusions (range, 4->500 RBC units) before bevacizumab initiation. The median length of follow-up was 17.6 months from the beginning of bevacizumab treatment (range, 3-42.5 months). There was a significant reduction in epistaxis severity scores (P<.001) and RBC transfusion requirements (P=.007) after completion of the initial bevacizumab treatment cycle. New-onset or worsened hypertension was noted in 4 patients, with 1 patient experiencing hypertensive urgency with a temporary decline in renal function. CONCLUSION Intravenous bevacizumab is an effective treatment option for patients with severe anemia related to epistaxis and/or gastrointestinal bleeding. Further studies are needed to establish a dose-response relationship as well as clinical, genetic, and biomarker predictors of response.

Abstract
Vascular anomalies comprise a spectrum of diseases that are broadly classified as tumors and malformations. Diagnosis is often challenging, given a wide range of clinical presentations with overlapping signs and symptoms. Accurate diagnosis is critical to determine prognosis and to generate a management plan, which frequently involves multiple subspecialists during different phases of treatment. An updated classification system provides structure and clear, consistent terminology, allowing for improved diagnosis, provider communication, and collaboration. Historically, treatment of vascular anomalies was primarily surgical and medical therapies were limited or ineffective. Recent discoveries of pharmacologic agents effective in treating vascular anomalies have broadened our medical therapeutic options, limiting the need for unnecessary or high-risk procedures and improving patients' quality of life.

Abstract
Objectives Hereditary hemorrhagic telangiectasia (HHT) is characterized by the presence of vascular malformations with an absence of capillaries between arteries and veins. One major manifestation site is the nasal mucous membrane where recurrent nosebleeds occur. Our clinical strategy to treat patients with HHT has the aim to reduce nasal bleeding long-term with minimal local and general side effects. Methods We describe staged diagnosis and therapy including individual medical treatments of 97 patients with HHT. The success of treatment is monitored with a systematic questionnaire. Results The neodymium-doped yttrium aluminium garnet (Nd:YAG) laser therapy remains standard treatment of choice with no major side effects despite the need for repeated treatment. In addition new treatment strategies like nasal occlusion, local drug therapy, and nasal septal splinting show initial success. Conclusion Improvement of the quality of life of HHT patients can be achieved by a multimodal concept. Several new treatment strategies like nasal septal splinting and nasal occlusion successfully expand the range of established methods. Further studies have to prove the safety and long-term effectiveness of the described individual medical treatments.

Abstract
BACKGROUND Hereditary haemorrhagic telangiectasia is a genetic disease that leads to multiregional angiodysplasia. Severe recurrent epistaxis is the most common presentation, frequently leading to severe anaemia. Several therapeutic approaches have been investigated, but they are mostly palliative and have had variable results. We aimed to assess the efficacy of thalidomide for the reduction of epistaxis in patients with hereditary haemorrhagic telangiectasia that is refractory to standard therapy. METHODS We recruited patients aged 17 years or older with hereditary haemorrhagic telangiectasia who had severe recurrent epistaxis refractory to minimally invasive surgical procedures into an open-label, phase 2, non-randomised, single-centre study at IRCCS Policlinico San Matteo Foundation (Pavia, Italy). We gave patients thalidomide at a starting dose of 50 mg/day orally. If they had no response, we increased the thalidomide dose by 50 mg/day increments every 4 weeks, until a response was seen, up to a maximum dose of 200 mg/day. After patients had achieved a response, they continued treatment for 8-16 additional weeks. The primary endpoint was the efficacy of thalidomide measured as the percentage of patients who had reductions of at least one grade in the frequency, intensity, or duration of epistaxis. We followed up patients each month to assess epistaxis severity score and transfusion need, and any adverse events were reported. We included all patients who received any study drug and who participated in at least one post-baseline assessment in the primary efficacy population. The safety population consisted of all patients who received any dose of study treatment. This trial is registered with ClinicalTrials.gov, number NCT01485224. FINDINGS Between Dec 1, 2011, and May 12, 2014, we enrolled 31 patients. Median follow-up was 15·9 months (IQR 10·1-22·3). Three (10%, 95% CI 2-26) patients had a complete response, with bleeding stopped, 28 (90%, 95% CI 74-98) patients had partial responses. Overall, all 31 (100%, 89-100) patients responded to therapy with a significant decrease in all epistaxis parameters (p<0·0001 for frequency, intensity, and duration). A response was achieved by 25 (81%) patients at 50 mg/day of thalidomide, five (16%) patients at 100 mg/day, and one (3%) patient at 150 mg/day. Patients had only non-serious, grade 1 adverse effects, the most common of which were constipation (21 patients), drowsiness (six patients), and peripheral oedema (eight patients). One patient died a month after the end of treatment, but this was not deemed to be related to treatment. INTERPRETATION Low-dose thalidomide seems to be safe and effective for the reduction of epistaxis in patients with hereditary haemorrhagic telangiectasia. Our findings should be validated by further studies with larger patient populations, longer follow-up, and that also assess the benefit for quality of life. FUNDING Telethon Foundation.

Abstract
BACKGROUND There are currently no guidelines in the UK for the specific management of hereditary haemorrhagic telangiectasia related epistaxis. The authors aimed to review the literature and provide an algorithm for the management of hereditary haemorrhagic telangiectasia related epistaxis. METHOD The Medline and Embase databases were interrogated on 15 November 2013 using the search items 'hereditary haemorrhagic telangiectasia' (title), 'epistaxis' (title) and 'treatment' (title and abstract), and limiting the search to articles published in English. RESULTS A total of 46 publications were identified, comprising 1 systematic review, 2 randomised, controlled trials, 27 case series, 9 case reports, 4 questionnaire studies and 3 in vitro studies. CONCLUSION There is a lack of high-level evidence for the use of many of the available treatments for the specific management of epistaxis in hereditary haemorrhagic telangiectasia. Current management should be based on a multidisciplinary team approach involving both a hereditary haemorrhagic telangiectasia physician and an ENT surgeon, especially when systemic therapy is being considered. The suggested treatment algorithm considers that the severity of epistaxis merits intervention at different levels of the treatment ladder. The patient should be assessed using a reproducible validated assessment tool, for example an epistaxis severity score, to guide treatment. More research is required, particularly in the investigation of topical agents targeting the development and fragility of telangiectasiae in hereditary haemorrhagic telangiectasia.

Abstract
Hereditary hemorrhagic telangiectasia (HHT), also known by the eponym Osler-Weber-Rendu syndrome, is a group of related disorders inherited in an autosomal dominant fashion and characterized by the development of arteriovenous malformations (AVM) in the skin, mucous membranes, and/or internal organs such as brain, lungs, and liver. Its prevalence is currently estimated at one in 5,000 to 8,000. Most cases are due to mutations in the endoglin (HHT1) or ACVRLK1 (HHT2) genes. Telangiectasias in nasal and gastrointestinal mucosa generally present with recurrent/chronic bleeding and iron deficiency anemia. Larger AVMs occur in lungs (~40%-60% of affected individuals), liver (~40%-70%), brain (~10%), and spine (~1%). Due to the devastating and potentially fatal complications of some of these lesions (for example, strokes and brain abscesses with pulmonary AVMs), presymptomatic screening and treatment are of utmost importance. However, due to the rarity of this condition, many providers lack an appreciation for the whole gamut of its manifestations and complications, age-dependent penetrance, and marked intrafamilial variation. As a result, HHT remains frequently underdiagnosed and many families do not receive the appropriate screening and treatments. This article provides an overview of the clinical features of HHT, discusses the clinical and genetic diagnostic strategies, and presents an up-to-date review of literature and detailed considerations regarding screening for visceral AVMs, preventive modalities, and treatment options.

Abstract
Patients harboring brain arteriovenous malformation (bAVM) are at life-threatening risk of rupture and intracranial hemorrhage (ICH). The pathogenesis of bAVM has not been completely understood. Current treatment options are invasive, and ≈ 20 % of patients are not offered interventional therapy because of excessive treatment risk. There are no specific medical therapies to treat bAVMs. The lack of validated animal models has been an obstacle for testing hypotheses of bAVM pathogenesis and testing new therapies. In this review, we summarize bAVM model development and bAVM pathogenesis and potential therapeutic targets that have been identified during model development.

Abstract
BACKGROUND Hereditary hemorrhagic telangiectasia (HHT) is a dominantly inherited genetic vascular disorder in which epistaxis is the most frequent manifestation, responsible for high morbidity. Management of this symptom has no standard, and local treatments are often aggressive. Their efficacy is variable and has not been proven. Anti-angiogenic drugs, such as bevacizumab, are a new treatment strategy. Its systemic administration in patients with HHT improves liver damage-related symptoms and epistaxis. To limit the systemic adverse effects of bevacizumab and to ease administration, a local administration seems suitable. PRIMARY OBJECTIVE To evaluate the tolerance of increasing doses of bevacizumab administered as a nasal spray in patients with HHT-related epistaxis. Secondary objectives were to study the bioavailability and efficacy of bevacizumab against epistaxis when given as a nasal spray. METHODOLOGY Phase 1, randomized, double-blind, placebo-controlled, monocentric study performed sequentially (dose escalation) on 5 groups of 8 patients. Each group was made up of 6 verum and 2 placebos. Five increasing doses of bevacizumab nasal spray (25 mg/mL) were evaluated: 12.5, 25, 50, 75 and 100 mg. RESULTS A total of 40 patients were included between October 2011 and October 2012. Bevacizumab nasal spray was well tolerated in all patients and the drug was not detected in their serum. No dose limiting toxicity was observed. No efficacy was observed at any dose in this study. CONCLUSION Based on these results, bevacizumab nasal spray is a safe treatment of epistaxis in HHT. However, a randomized Phase 2 study is needed to determine its efficacy. TRIAL REGISTRATION ClinicalTrials.gov Identifier #NCT01507480.

Abstract
BACKGROUND The aim of this study was to identify and evaluate adverse clinical outcomes following office-based sclerotherapy using sodium tetradecyl sulfate (STS) for epistaxis due to hereditary hemorrhagic telangiectasias (HHT or Osler-Weber-Rendu). METHODS A retrospective chart review of 36 adult patients treated with STS sclerotherapy for severe and/or recurrent epistaxis due to HHT was performed. RESULTS A total of 153 separate treatment sessions were analyzed. Each patient underwent an average of 4.3 sessions with an average of 7 intralesional injections per session. Bleeding during the procedure was experienced by 8 patients with a maximum reported blood loss of 200 mL in 1 patient, but less than 50 mL in all others. Seven patients reported some postinjection pain, which included nasal, cheek, and eye pain. Nasal congestion, sneezing, and vasovagal responses were each noted to occur 2 times. No complications of postprocedural visual loss, deep venous thrombosis/pulmonary embolus, transient ischemic attack (TIA)/stroke, or anaphylaxis were encountered. CONCLUSION Conventional therapies used in the management of HHT-related epistaxis, such as laser coagulation, septodermoplasty, selective arterial embolization, and Young's occlusion each have specific associated complications, including worsened epistaxis, septal perforation, foul odor, nasal crusting, and compromised nasal breathing. STS is a safe office-based treatment option for HHT-mediated epistaxis that is associated with exceedingly few of the aforementioned serious sequelae.

Abstract
A patient with hereditary hemorrhagic telangiectasia is a rare presentation to the otolaryngologist in clinical practice. They almost present with epistaxis, which is recurrent, spontaneous and can be functionally and socially debilitating for the patient. Diode laser cauterization and Avastin intranasal injection showed significant improvement in epistaxis severity score. We report a case of hereditary hemorrhagic telangiectasia with chronic epistaxis (hemoglobin 3.4 mg/dl) managed with Diode laser and intranasal Avastin injection with great improvement in life quality and decrease in epistaxis attacks. Despite all treatment options absolute eradication of epistaxis attacks is difficult to obtain in these cases.

Abstract
OBJECTIVE/HYPOTHESIS To evaluate the effectiveness of a standardized intranasal bevacizumab injection in treating hereditary hemorrhagic telangiectasia (HHT)-associated epistaxis. STUDY DESIGN Prospective pilot study. METHODS A total dose of 100 mg bevacizumab (25 mg/mL Avastin) was injected submucosally, 50 mg on each side. A total of 0.5 mL was injected in the sphenopalatine area, upper part of bony septum, upper part of the later nasal wall, and the anterior part of nasal floor. No cauterizations or laser therapy were done during or after the procedure. The hemoglobin level and grades of epistaxis were recorded before and monthly after the procedure. The IFT grading system (intensity [I], frequency [F] of epistaxis, and the amount of blood transfusion [T]) and epistaxis severity score (ESS) for hereditary hemorrhagic telangiectasia system were used. Quality of life (QoL) was evaluated before and 4 weeks after the procedure using the Short Form-36 Health Survey questionnaire, Cantril's Self-Anchoring Ladder questionnaire, and Slotosch disease-specific QoL questionnaire. RESULTS A significant improvement was found in IFT grading (P = .007), ESS grading (P = .001), and hemoglobin level (P = .01). The QoL differences were statistically not significant. CONCLUSIONS The four-injection site technique of intranasal administration of bevacizumab is an effective treatment option in HHT-associated epistaxis, at least on the short-term effect. Long-term and comparative studies are needed to further evaluate the significance of this treatment modality.

Abstract
Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal-dominantly inherited disease that occurs in approximately one in 5000 to 8000 people. Clinical diagnosis of HHT is made when a person presents three of the following four criteria: family history, recurrent nosebleeds, mucocutaneous telangiectasis, and arteriovenous malformations (AVM) in the brain, lung, liver and gastrointestinal (GI) tract. Although epistaxis is the most common presenting symptom, AVMs affecting the lungs, brain and GI tract provoke a more serious outcome. Heterozygous mutations in endoglin, activin receptor-like kinase 1 (ACVRL1; ALK1), and SMAD4, the genes involved in the transforming growth factor-β family signaling cascade, cause HHT. We report here the case of a 63 year-old male patient who presented melena and GI bleeding episodes, proven to be caused by bleeding from multiple gastric angiodysplasia. Esophagogastroduodenoscopy revealed multiple angiodysplasia throughout the stomach. Endoscopic argon plasma coagulation was performed to control bleeding from a gastric angiodysplasia. The patient has been admitted several times with episodes of hemoptysis and hematochezia. One year ago, the patient was hospitalized due to right-sided weakness, which was caused by left basal ganglia hemorrhage as the part of HHT presentation. In family history, the patient’s mother and elder sister had died, due to intracranial hemorrhage, and his eldest son has been suffered from recurrent epistaxis for 20 years. A genetic study revealed a mutation in exon 3 of ALK1 (c.199C > T; p.Arg67Trp) in the proband and his eldest son presenting epistaxis.
