Development and performance of a hereditary hemorrhagic telangiectasia-specific quality-of-life instrument.

ABSTRACT: Hereditary hemorrhagic telangiectasia (HHT) is characterized by arteriovenous malformations and telangiectasia, with primary clinical manifestations of epistaxis and gastrointestinal bleeding and resultant anemia. HHT negatively affects health-related quality of life (HR-QoL); however, existing tools to measure HR-QoL are not HHT specific. Our objective was to develop an HHT-specific HR-QoL (HHT-QoL) instrument and evaluate its performance in a cross-sectional survey of individuals with HHT. Four HHT-specific questions were developed to evaluate the impact of HHT on productivity and social and personal interactions. An anonymous e-mail survey was conducted through Cure HHT. Participants also indicated their perceived HHT severity and completed 3 Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaires: Discretionary Social Activities, Social Roles, and Emotional Distress. Complete data were available for 290 participants who self-identified their HHT severity as mild (29%), moderate (46%), or severe (25%). The HHT-QoL scale was reliable (Cronbach's-α, 0.83). Principal components analysis indicated the instrument was unidimensional. Participants had low levels of QoL with their ability to participate in discretionary social activities (PROMIS mean 36.4 [standard deviation 14.3]) and perform in social roles (41.5 [17.2]), and the presence of a high level of emotional distress (64.8 [24.2]). The HHT-QoL score correlated negatively with PROMIS Discretionary Social Activities (r = -0.65) and Social Roles (r = -0.68) and positively correlated with PROMIS Emotional Distress (r = 0.51). In conclusion, the 4-item HHT-QoL instrument provides valuable insight and may be a useful addition to future clinical research in HHT.

Project description:BackgroundHereditary hemorrhagic telangiectasia (HHT) disease is a rare genetic disorder with symptoms and complications that can significantly affect patients' daily lives. To date, no scale has been validated to assess the specific symptoms of this disease on the quality of life (QOL) of HHT patients. This makes it difficult for clinicians to accurately measure the quality of life of patients with HHT. The present study aims to develop and validate a QOL measurement tool specific to HHT disease: the QOL questionnaire in HHT (QoL-HHT).MethodsA quantitative, non-interventional, multi-center study involving HHT patients in twenty French HHT expert centers was conducted. A calibration sample of 415 HHT patients and a validation sample of 228 HHT patients voluntarily participated in the study. Data were analyzed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), Exploratory Structural Equation Modeling (ESEM) analyses, reliability analyses, and correlational analyses.ResultsThe EFA, CFA and ESEM results allowed us to provide evidence of the factorial structure of a questionnaire composed of 24 items measuring 6 domains of QOL: Physical limitations, social relationships, concern about bleeding, relationship with the medical profession, experience of symptoms, and concern about the evolution of the disease. Cronbach's alpha coefficients (> 0.70) demonstrated reliable internal consistency of all the QoL-HHT scores (dimensions). The results of the test-retest provided further evidence of the reliability of the QOL-HHT scores over time. Correlational analyses provided evidence for the convergent validity of the QoL-HHT scores.ConclusionsWe developed a simple and quick self-assessment tool to measure quality of life specific to HHT disease. This study demonstrated reliability and validity of our QoL-HHT scores. It is a very promising tool to evaluate the impact of HHT disease on all aspects of the quality of life of HHT patients in order to offer them individualized medico-psycho-social support.Trial registrationClinicalTrials, NCT03695874.

Project description:Background and purposeThe presence of malformations of cortical development in patients with hereditary hemorrhagic telangiectasia has been reported on previous occasions. We evaluated a sample of adults with hereditary hemorrhagic telangiectasia for the presence of malformations of cortical development, spatial coincidence of malformations of cortical development and AVMs, and the coincidence of brain and pulmonary AVMs.Materials and methodsA total of 141 patients 18 years of age or older who were referred to the Augusta University hereditary hemorrhagic telangiectasia clinic and underwent brain MR imaging between January 19, 2018, and December 3, 2020, were identified. MR imaging examinations were reviewed retrospectively by 2 experienced neuroradiologists, and the presence of malformations of cortical development and AVMs was confirmed by consensus. Demographic and clinical information was collected for each case, including age, sex, hereditary hemorrhagic telangiectasia status by the Curacao Criteria, mutation type, presence of malformations of cortical development, presence of brain AVMs, presence of pulmonary AVMs, and a history of seizures or learning disabilities.ResultsFive of 141 (3.5%) patients with hereditary hemorrhagic telangiectasia had malformations of cortical development. Two of the 5 patients with polymicrogyria also had closed-lip schizencephaly. One of the patients had a porencephalic cavity partially lined with heterotopic GM. The incidence of spatially coincident polymicrogyria and brain AVMs was 40% (2/5 cases). Of the patients with hereditary hemorrhagic telangiectasia and malformations of cortical development, 4/5 (80%) had pulmonary AVMs and 2/5 (40%) had brain AVMs.ConclusionsTo our knowledge, we are the first group to report the presence of schizencephaly in patients with hereditary hemorrhagic telangiectasia. The presence of schizencephaly and porencephaly lends support to the hypothesis of regional in utero cerebral hypoxic events as the etiology of malformations of cortical development in hereditary hemorrhagic telangiectasia.

Project description:BackgroundDespite the considerable burden that hereditary hemorrhagic telangiectasia (HHT) imposes, few studies have investigated its effect on health-related quality of life (HRQoL). We aimed to assess the impact of HHT on psychosocial QoL and identify demographic and clinical factors associated with lower QoL.MethodsWe conducted an international, cross-sectional study of 1042 adults with HHT within the Cure HHT network, between 2022 and 2023. We used an online survey that included 5 standardized instruments to evaluate patients' perceptions of the impact of HHT on their QoL: Epistaxis Severity Score (ESS); Nasal Outcome Score for Epistaxis in Hereditary Hemorrhagic Telangiectasia (NOSE-HHT); Patient-Reported Outcomes Measurement Information System (PROMIS) Fatigue - Short Form 8a - Fatigue interfere scale (PROMIS-Fatigue 8a); Hospital Anxiety and Depression Scale (HADS-A and HADS-D); and Short Form Health Survey (SF-36). Statistical analyses included Spearman's correlations, univariate analyses, Tukey's honestly significant difference, and Kruskal-Wallis tests.Results565/1042 (54%) participants completed the survey. The most common symptoms were epistaxis 521/565 (92%) and fatigue 446/565 (79%). There were strong positive correlations between HADS-A and ESS (2.6 [95% CI 1.7-3.6]) and NOSE-HHT (4 [3.2-5]); HADS-D and ESS (1.4 [1.3-1.5]) and NOSE-HHT (4.4 [3.4-5.7]); PROMIS Fatigue 8a and ESS (8.2 [6.3-10]) and NOSE-HHT (5.9 [5.2-6.6]); and SF-36 scores and ESS (- 26.4 [- 33 to - 19.9]) and NOSE-HHT (- 33.1 [- 39.7 to - 28.6]). Liver failure and seizures indicated a higher likelihood of depression (3.1 [1-5.2]), anxiety (3 [0.6-5.4]), and fatigue (9.6 [4.7-14.5]). Seizures were associated with depression (2.9 [1.8-3.9]), anxiety (2.9 [1.7-4.1]), and fatigue (5 [2.34-7.7]). Participants expressed a substantial effect on their physical (143/560 [25%]), role (140/556 [25%]), emotional (124/554 [22%]), social (104/556 [18%]), and cognitive (64/550 [11%]) functioning. However, more participants considered extremely important to improve their physical (289/560 [51%]), cognitive (266/550 [47%]), role (253/556 [43%]), emotional (243/554 [45%]), and social (233/556 [41%]) functioning affected by HHT.ConclusionsSevere epistaxis is associated with higher rates of depression, anxiety, and fatigue. Participants expressed desire for improvement in a broad range of functional domains disturbed by HHT. This suggests a need for increased awareness, resources, and more effective interventions to improve the QOL of patients with HHT.

Project description:BackgroundHereditary hemorrhagic telangiectasia (HHT) is characterized by extensive telangiectasias and arteriovenous malformations. The primary clinical manifestation is epistaxis that results in iron-deficiency anemia and reduced health-related quality of life.MethodsWe conducted a randomized, placebo-controlled trial to evaluate the safety and efficacy of pomalidomide for the treatment of HHT. We randomly assigned patients, in a 2:1 ratio, to receive pomalidomide at a dose of 4 mg daily or matching placebo for 24 weeks. The primary outcome was the change from baseline through week 24 in the Epistaxis Severity Score (a validated bleeding score in HHT; range, 0 to 10, with higher scores indicating worse bleeding). A reduction of 0.71 points or more is considered clinically significant. A key secondary outcome was the HHT-specific quality-of-life score (range, 0 to 16, with higher scores indicating more limitations).ResultsThe trial was closed to enrollment in June 2023 after a planned interim analysis met a prespecified threshold for efficacy. A total of 144 patients underwent randomization; 95 patients were assigned to receive pomalidomide and 49 to receive placebo. The baseline mean (±SD) Epistaxis Severity Score was 5.0±1.5, a finding consistent with moderate-to-severe epistaxis. At 24 weeks, the mean difference between the pomalidomide group and the placebo group in the change from baseline in the Epistaxis Severity Score was -0.94 points (95% confidence interval [CI], -1.57 to -0.31; P = 0.004). The mean difference in the changes in the HHT-specific quality-of-life score between the groups was -1.4 points (95% CI, -2.6 to -0.3). Adverse events that were more common in the pomalidomide group than in the placebo group included neutropenia, constipation, and rash.ConclusionsAmong patients with HHT, pomalidomide treatment resulted in a significant, clinically relevant reduction in epistaxis severity. No unexpected safety signals were identified. (Funded by the National Heart, Lung, and Blood Institute; PATH-HHT Clinicaltrials.gov number, NCT03910244).
