Background: EPHB4 loss of function is associated with type 2 capillary malformation-arteriovenous malformation syndrome, an autosomal dominant vascular disorder. The phenotype partially overlaps with hereditary haemorrhagic telangiectasia (HHT) due to epistaxis, telangiectases and cerebral arteriovenous malformations, but a similar liver involvement has never been described., Methods: Members of the French HHT network reported their cases of EPHB4 mutation identified after an initial suspicion of HHT. Clinical, radiological and genetic characteristics were analysed., Results: Among 21 patients with EPHB4 , 15 had a liver imaging, including 7 with HHT-like abnormalities (2 female patients and 5 male patients, ages 43-69 years). Atypical epistaxis and telangiectases were noted in two cases each. They were significantly older than the eight patients with normal imaging (median: 51 vs 20 years, p<0.0006).The main hepatic artery was dilated in all the cases (diameter: 8-11 mm). Six patients had hepatic telangiectases. All kind of shunts were described (arteriosystemic: five patients, arterioportal: two patients, portosystemic: three patients). The overall liver appearance was considered as typical of HHT in six cases.Six EPHB4 variants were classified as pathogenic and one as likely pathogenic, with no specific hot spot., Conclusion: EPHB4 loss-of-function variants can be associated with HHT-like hepatic abnormalities and should be tested for atypical HHT presentations., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Riociguat and balloon pulmonary angioplasty (BPA) are treatment options for inoperable chronic thromboembolic pulmonary hypertension (CTEPH). However, randomised controlled trials comparing these treatments are lacking. We aimed to evaluate the efficacy and safety of BPA versus riociguat in patients with inoperable CTEPH., Methods: In this phase 3, multicentre, open-label, parallel-group, randomised controlled trial done in 23 French centres of expertise for pulmonary hypertension, we enrolled treatment-naive patients aged 18-80 years with newly diagnosed, inoperable CTEPH and pulmonary vascular resistance of more than 320 dyn·s/cm 5 . Patients were randomly assigned (1:1) to BPA or riociguat via a web-based randomisation system, with block randomisation (block sizes of two or four patients) without stratification. The primary endpoint was change in pulmonary vascular resistance at week 26, expressed as percentage of baseline pulmonary vascular resistance in the intention-to-treat population. Safety analyses were done in all patients who received at least one dose of riociguat or had at least one BPA session. Patients who completed the RACE trial continued into an ancillary 26-week follow-up during which symptomatic patients with pulmonary vascular resistance of more than 320 dyn·s/cm 5 benefited from add-on riociguat after BPA or add-on BPA after riociguat. This trial is registered at ClinicalTrials.gov, NCT02634203, and is completed., Findings: Between Jan 19, 2016, and Jan 18, 2019, 105 patients were randomly assigned to riociguat (n=53) or BPA (n=52). At week 26, the geometric mean pulmonary vascular resistance decreased to 39·9% (95% CI 36·2-44·0) of baseline pulmonary vascular resistance in the BPA group and 66·7% (60·5-73·5) of baseline pulmonary vascular resistance in the riociguat group (ratio of geometric means 0·60, 95% CI 0·52-0·69; p<0·0001). Treatment-related serious adverse events occurred in 22 (42%) of 52 patients in the BPA group and five (9%) of 53 patients in the riociguat group. The most frequent treatment-related serious adverse events were lung injury (18 [35%] of 52 patients) in the BPA group and severe hypotension with syncope (two [4%] of 53 patients) in the riociguat group. There were no treatment-related deaths. At week 52, a similar reduction in pulmonary vascular resistance was observed in patients treated with first-line riociguat or first-line BPA (ratio of geometric means 0·91, 95% CI 0·79-1·04). The incidence of BPA-related serious adverse events was lower in patients who were pretreated with riociguat (five [14%] of 36 patients vs 22 [42%] of 52 patients)., Interpretation: At week 26, pulmonary vascular resistance reduction was more pronounced with BPA than with riociguat, but treatment-related serious adverse events were more common with BPA. The finding of fewer BPA-related serious adverse events among patients who were pretreated with riociguat in the follow-up study compared with those who received BPA as first-line treatment points to the potential benefits of a multimodality approach to treatment in patients with inoperable CTEPH. Further studies are needed to explore the effects of sequential treatment combining one or two medications and BPA in patients with inoperable CTEPH., Funding: Programme Hospitalier de Recherche Clinique of the French Ministry of Health and Bayer HealthCare., Translation: For the French translation of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests XJ, PB, HB, MJ, LS, OS, FP, CP, LG, EF, DM, MH, and GS report grants from the French Ministry of Health and Bayer HealthCare, during the conduct of the study.

Background: Hereditary 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)., Methods: A 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., Results: The 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., Conclusions: We 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 Registration: ClinicalTrials, NCT03695874.

Rationale: The relationship between the initial treatment strategy and survival in pulmonary arterial hypertension (PAH) remains uncertain. Objectives: To evaluate the long-term survival of patients with PAH categorized according to the initial treatment strategy. Methods: A retrospective analysis of incident patients with idiopathic, heritable, or anorexigen-induced PAH enrolled in the French Pulmonary Hypertension Registry (January 2006 to December 2018) was conducted. Survival was assessed according to the initial strategy: monotherapy, dual therapy, or triple-combination therapy (two oral medications and a parenteral prostacyclin). Measurements and Main Results: Among 1,611 enrolled patients, 984 were initiated on monotherapy, 551 were initiated on dual therapy, and 76 were initiated on triple therapy. The triple-combination group was younger and had fewer comorbidities but had a higher mortality risk. The survival rate was higher with the use of triple therapy (91% at 5 yr) as compared with dual therapy or monotherapy (both 61% at 5 yr) ( P  < 0.001). Propensity score matching of age, sex, and pulmonary vascular resistance also showed significant differences between triple therapy and dual therapy (10-yr survival, 85% vs. 65%). In high-risk patients ( n  = 243), the survival rate was higher with triple therapy than with monotherapy or dual therapy, whereas there was no difference between monotherapy and double therapy. In intermediate-risk patients ( n  = 1,134), survival improved with an increasing number of therapies. In multivariable Cox regression, triple therapy was independently associated with a lower risk of death (hazard ratio, 0.29; 95% confidence interval, 0.11-0.80; P  = 0.017). Among the 148 patients initiated on a parenteral prostacyclin, those on triple therapy had a higher survival rate than those on monotherapy or dual therapy. Conclusions: Initial triple-combination therapy that includes parenteral prostacyclin seems to be associated with a higher survival rate in PAH, particularly in the youngest high-risk patients.

Rationale: Pulmonary hypertension (PH) associated with neurofibromatosis type 1 (NF1) is a rare and largely unknown complication of NF1. Objectives: To describe characteristics and outcomes of PH-NF1. Methods: We reported the clinical, functional, radiologic, histologic, and hemodynamic characteristics, response to pulmonary arterial hypertension (PAH)-approved drugs, and transplant-free survival of patients with PH-NF1 from the French PH registry. Measurements and Main Results: We identified 49 PH-NF1 cases, characterized by a female/male ratio of 3.9 and a median (minimum-maximum) age at diagnosis of 62 (18-82) years. At diagnosis, 92% were in New York Heart Association functional class III or IV. The 6-minute-walk distance was 211 (0-460) m. Pulmonary function tests showed low Dl CO (30% [12-79%]) and severe hypoxemia (Pa O 2 56 [38-99] mm Hg). Right heart catheterization showed severe precapillary PH with a mean pulmonary artery pressure of 45 (10) mm Hg and a pulmonary vascular resistance of 10.7 (4.2) Wood units. High-resolution computed tomography images revealed cysts (76%), ground-glass opacities (73%), emphysema (49%), and reticulations (39%). Forty patients received PAH-approved drugs with a significant improvement in functional class and hemodynamic parameters. Transplant-free survival at 1, 3, and 5 years was 87%, 54%, and 42%, respectively, and four patients were transplanted. Pathologic assessment showed nonspecific interstitial pneumonia and major pulmonary vascular remodeling. Conclusions: PH-NF1 is characterized by a female predominance, a low Dl CO , and severe functional and hemodynamic impairment. Despite a potential benefit of PAH treatment, prognosis remains poor, and double-lung transplantation is an option for eligible patients.

Background & Aims: Long-term outcomes in portopulmonary hypertension (PoPH) are poorly studied in the current era of pulmonary hypertension management. We analysed the effect of pulmonary arterial hypertension (PAH)-targeted therapies, survival and predictors of death in a large contemporary cohort of patients with PoPH., Methods: Data from patients with PoPH consecutively enrolled in the French Pulmonary Hypertension Registry between 2007 and 2017 were collected. The effect of initial treatment strategies on functional class, exercise capacity and cardiopulmonary haemodynamics were analysed. Survival and its association with PAH- and hepatic-related characteristics were also examined., Results: Six hundred and thirty-seven patients (mean age 55 ± 10 years; 58% male) were included. Fifty-seven percent had mild cirrhosis, i.e. Child-Pugh stage A. The median model for end-stage liver disease (MELD) score was 11 (IQR 9-15). Most patients (n = 474; 74%) were initiated on monotherapy, either with a phosphodiesterase-5 inhibitor (n = 336) or with an endothelin-receptor antagonist (n = 128); 95 (15%) were initiated on double oral combination therapy and 5 (1%) on triple therapy. After a median treatment time of 4.5 months, there were significant improvements in functional class (p <0.001), 6-minute walk distance (6MWD) (p <0.0001) and pulmonary vascular resistance (p <0.0001). Overall survival rates were 84%, 69% and 51% at 1, 3 and 5 years, respectively. Baseline 6MWD, sex, age and MELD score or Child-Pugh stage were identified as independent prognostic factors. Survival from PoPH diagnosis was significantly better in the subgroup of patients who underwent liver transplantation (92%, 83% and 81% at 1, 3 and 5 years, respectively)., Conclusion: Survival of patients with PoPH is strongly associated with the severity of liver disease. Patients who underwent liver transplantation had the best long-term outcomes., Lay Summary: Portopulmonary hypertension is defined by the presence of pulmonary arterial hypertension in the context of chronic liver disease and is characterized by progressive shortness of breath and exercise limitation. The presence of severe pulmonary arterial hypertension in liver transplant candidates represents a contraindication for such a surgery; however, treatments targeting pulmonary arterial hypertension are efficacious, allowing for safe transplantation and conferring good survival outcomes in those who undergo liver transplantation., Competing Interests: Conflict of interest LS reports grants and personal fees from Actelion, grants and personal fees from MSD, grants and personal fees from GSK, outside the submitted work.

Background: Portopulmonary hypertension is defined by the presence of pulmonary arterial hypertension associated with portal hypertension. Its presence is a major stake for cirrhotic patients requiring liver transplantation (LT), with increased postoperative mortality and unpredictable evolution after transplantation. The aim was to study outcomes after liver transplantation in patients with portopulmonary hypertension and to identify factors associated with normalization of pulmonary hypertension., Methods: Patients with portopulmonary hypertension who underwent LT between 2008 and 2016 in 8 French centers were retrospectively included. Pulmonary artery pressure was established by right heart catheterization before and after LT. Primary endpoint was the normalization of pulmonary artery pressure after LT., Results: Twenty-three patients who received liver transplant between 2008 and 2016 were included. Two (8.7%) patients died in the immediate posttransplant period from right heart failure. With appropriate vasoactive medical treatment and LT, pulmonary arterial pressure was normalized in 14 patients (60.8%), demonstrating recovery from portopulmonary hypertension. In univariate analysis, the use of vasoactive combination therapy was the only prognostic factor for pulmonary arterial hypertension normalization after LT., Conclusions: Treatment of portopulmonary hypertension with a combination of vasoactive drugs allows LT with acceptable postoperative cardiovascular-related mortality and normalization of pulmonary hypertension in the majority of the patients.

This study aimed to describe the long-term outcomes of pulmonary arterial hypertension (PAH) induced by dasatinib.21 incident, right heart catheterisation-confirmed cases of dasatinib-induced PAH were identified from the French Pulmonary Hypertension Registry. Clinical and haemodynamic variables were compared from baseline to last follow-up (median (range) 24 (1-81) months).Median age was 52 years and 15 patients were female (71%). 19 patients received dasatinib for chronic myelogenous leukaemia for a median (range) duration of 42 (8-74) months before PAH diagnosis. No bone morphogenic protein receptor-2 ( BMPR2 ) mutations were found in the 10 patients tested. Dasatinib was uniformly discontinued and 11 patients received PAH medications. Four patients died during follow-up. New York Heart Association functional class improved from 76% in class III/IV to 90% in class I/II (p<0.01). Median (range) 6-min walk distance improved from 306 (0-660) to 430 (165-635) m (p<0.01). Median (range) mean pulmonary arterial pressure improved from 45 (30-70) to 26 (17-50) mmHg (p<0.01) and pulmonary vascular resistance from 6.1 (3.2-27.3) to 2.6 (1.2-5.9) Wood units (p<0.01). Patients treated with PAH medications had worse baseline haemodynamics but similar long-term outcomes to untreated patients. PAH persisted in 37% of patients.Dasatinib-induced PAH frequently improves after discontinuation but persisted in over one-third of patients, therefore systematic follow-up is essential., Competing Interests: Conflict of interest: Disclosures can be found alongside this article at erj.ersjournals.com, (Copyright ©ERS 2017.)

Objectives: Despite the wide use of the 6 min walk distance (6MWD), no study has ever assessed its validity as a surrogate marker for haemodynamics and predictor of outcome in isolated pulmonary arterial hypertension associated with systemic sclerosis (SSc-PAH). We designed this work to address this issue., Methods: Treatment-naïve patients with SSc-PAH were prospectively included from two sources: the French PAH Network (a prospective epidemiological cohort) (n=83) and randomised clinical trials submitted for drug approval (Food and Drug Administration) (n=332). Correlations between absolute values of the 6MWD and haemodynamics at baseline, as well as between variations of 6MWD and haemodynamics during follow-up, were studied in both populations., Results: In the French cohort, baseline cardiac output (CO) (R(2)=0.19, p=0.001) and New York Heart Association class (R(2)=0.10, p<0.001) were significantly and independently correlated with baseline 6MWD in multivariate analysis. A significant, independent, but weaker, correlation with CO was also found in the Food and Drug Administration sample (R(2)=0.04, p<0.001). During follow-up, there was no association between the changes in 6MWD and haemodynamic parameters in patients under PAH-specific treatments., Conclusions: In SSc-PAH, CO independently correlates with 6MWD at baseline, but accounts for a small amount of the variance of 6MWD in both study samples. This suggests that other non-haemodynamic factors could have an impact on the walk distance. Moreover, variations of 6MWD do not reflect changes in haemodynamics among treated patients. Our results suggest that 6MWD is not an accurate surrogate marker for haemodynamic severity, nor an appropriate outcome measure to assess changes in haemodynamics during follow-up in treated SSc-PAH., (Published by the BMJ Publishing Group Limited.

Objectives: Our study purports to determine whether implantation of a prophylactic pacemaker in MD patients with HV interval ≥ 70 ms lowers the risk of sudden death, which may be essentially due to complete atrioventricular block., Background: Sudden death occurs more frequently in patients with myotonic dystrophy (MD) than in the control population., Methods: From 1994 to 2008, 100 consecutive patients were enrolled, 49 of whom were implanted., Results: During an average follow-up of 74 ± 39 months, 10 deaths occurred. Nine were due to respiratory failure. Only one sudden death occurred, whereas 46% of patients were considered at risk of sudden death according to the criteria of Groh et al. [5]. The incidence rate of sudden death was only 0.2 per 100 patient-years. One patient developed a paroxysmal syncopal sustained ventricular tachycardia., Conclusions: The prophylactic implantation of PM in MD patients who are identified as being at risk of sudden death according to Groh's criteria reduced the incidence rate of sudden death. The one sudden death in an implanted MD patient suggests the likelihood that pacemaker implantation did not totally forestall this event. Ventricular arrhythmias may be involved in the sudden deaths in MD patients, in which case the implantation of an implantable cardiac defibrillator could be indicated., (Copyright © 2010 Elsevier Ireland Ltd.

Purpose: To explore the feasability of imaging lung masses with a novel endobronchial linear-array transducer., Method: We used a linear-array transducer of 7 F (2.3 mm in diameter) operating at a center frequency of 10 MHz for endobronchial imaging. We used the probe in 20 subjects with suspected lung cancer to identify and measure the tumor; to asses the tumor's sonographic characteristics, bronchial wall invasion, and presence of lymph nodes; to guide a transbronchial needle aspiration (TBNA); and to evaluate potential side effects., Results: In all patients, the tumor was identified and the relationship with the bronchial wall correctly evaluated through the depiction of a 3-layer wall pattern. Bronchial wall invasion was suspected in 5 patients, small adjacent lymph nodes were detected in 3 patients, and a small pleural effusion was observed close to the lung lesion in 2 patients. The linear-array probe allowed the guidance of successful TBNA with no complications., Conclusion: This feasibility study shows that the prototype probe can be used to depict pulmonary lesions and to guide biopsy nodes. Larger series are needed to validate its usefulness in clinical work-ups and patients management.

Objective: Invasive aspergillosis is associated with a poor prognosis, especially in critically ill patients with cerebral involvement. We present two cases of cerebral invasive aspergillosis successfully treated in the intensive care unit with combination antifungal therapies and without surgery., Case Presentation: The first patient was a 49-year-old man with rheumatoid arthritis who received corticosteroid and cyclophosphamide treatment and developed pulmonary and cerebral invasive aspergillosis. After failure of voriconazole the patient had a successful outcome with voriconazole and liposomal amphotericin B therapy. The patient returned home after an 8-month hospital stay. The second patient was a 54-year-old woman with pulmonary neoplasia and corticosteroid treatment who developed pulmonary and cerebral invasive aspergillosis. After failure of voriconazole and liposomal amphotericin B therapy the patient had a favorable outcome with liposomal amphotericin B and caspofungin therapy. The patient died 10 months after initial diagnosis of cardiac tamponade unrelated to fungal infection., Discussions: These cases illustrate the improving prognosis of invasive aspergillosis due to the availability of new treatments, especially in cases of cerebral involvement. It also demonstrates that the outcome of critically ill patients requiring mechanical ventilation for invasive aspergillosis can be favorable. The treatment of patients with invasive cerebral aspergillosis in the intensive care setting should be encouraged.
