Résumé : International audience
BACKGROUND: Mutations in the telomerase complex (TERT and TR) are associated with pulmonary fibrosis and frequent hematologic manifestations. The aim of this study was to characterize the prognosis of lung transplantation in patients with TERT or TR mutations. METHODS: Patients with documented TERT or TR mutations who received a lung transplant between 2007 and 2013 in France were identified via an exhaustive search of the lung transplantation network, one expert genetic laboratory, and the clinical research network on rare pulmonary diseases. RESULTS: There were 9 patients (7 men) with TERT (n = 6) or TR (n = 3) mutations who received a single (n = 8) or a double (n = 1) lung transplant for pulmonary fibrosis. Median age was 50 years (range, 35-61 years) at diagnosis and 52 years (range, 37-62 years) at the time of lung transplantation. Thrombocytopenia was present in 7 patients before lung transplantation. After lung transplantation, 6 patients developed myelodysplasia and/or bone marrow failure, directly contributing to death in 4 cases. Anemia was observed in 9 patients, and neutropenia was observed in 3 patients. The median survival after lung transplantation was 214 days (range, 59-1,709 days). CONCLUSIONS: Patients with mutations of the telomerase complex are at high risk of severe hematologic complications after lung transplantation, in particular, bone marrow failure. Specific recommendations should be developed for appropriate guidance regarding hematologic risk assessment before transplantation and management of the post-transplantation immunosuppressive regimen.

Résumé : International audience
Objective To guide nosology and classification of patients with eosinophilic granulomatosis with polyangiitis (EGPA) based on phenotype and presence or absence of ANCA. Methods Organ manifestations and ANCA status were retrospectively analyzed based on the presence or not of predefined definite vasculitis features or surrogates of vasculitis in patients asthma, eosinophilia, and at least one systemic organ manifestation attributable to systemic disease. Results The study population included 157 patients (mean age 49.4 ± 14.1), with a follow-up of 7.4 ± 6.4 years. Patients with ANCA (31%) more frequently had weight loss, myalgias, arthralgias, biopsy-proven vasculitis, glomerulonephritis on biopsy, hematuria, leukocytoclastic capillaritis and/or eosinophilic infiltration of arterial wall on biopsy, and other renal disease. A total of 41% of patients had definite vasculitis manifestations (37%) or strong surrogates of vasculitis (4%), of whom only 53% had ANCA. Mononeuritis multiplex was associated with systemic vasculitis (p = 0.005) and with the presence of ANCA (p < 0.001). Overall, 59% of patients had polyangiitis as defined by definite vasculitis, strong surrogate of vasculitis, mononeuritis multiplex, and/or ANCA with at least one systemic manifestation other than ENT or respiratory. Patients with polyangiitis had more systemic manifestations including arthralgias (p = 0.02) and renal disease (p = 0.024), had higher peripheral eosinophilia (p = 0.027), and a trend towards less myocarditis (p = 0.057). Using predefined criteria of vasculitis and surrogates of vasculitis, ANCA alone were found to be insufficient to categorise patients with vasculitis features. Conclusion We suggest a revised nomenclature and definition for EGPA and a new proposed entity referred to as hypereosinophilic asthma with systemic (non vasculitic) manifestations. © 2016 Elsevier B.V.

Résumé : International audience
Idiopathic pulmonary fibrosis (IPF) is the most frequent chronic idiopathic interstitial pneumonia in adults. The management of rare diseases in France has been organised by a national plan for rare diseases, which endorsed a network of expert centres for rare diseases throughout France. This article is an overview of the executive summary of the French guidelines for the management of IPF, an initiative that emanated from the French National Reference Centre and the Network of Regional Competence Centres for Rare Lung Diseases. This review aims at providing pulmonologists with a document that: 1) combines the current available evidence; 2) reviews practical modalities of diagnosis and management of IPF; and 3) is adapted to everyday medical practice. The French practical guidelines result from the combined efforts of a coordination committee, a writing committee and a multidisciplinary review panel, following recommendations from the Haute Autorité de Santé. All recommendations included in this article received at least 90% agreement by the reviewing panel. Herein, we summarise the main conclusions and practical recommendations of the French guidelines.

Résumé : International audience
BACKGROUND: The timing of cardiac surgery after stroke in infective endocarditis (IE) remains controversial. We examined the relationship between the timing of surgery after stroke and the incidence of in-hospital and 1-year mortalities. METHODS: Data were obtained from the International Collaboration on Endocarditis-Prospective Cohort Study of 4794 patients with definite IE who were admitted to 64 centers from June 2000 through December 2006. Multivariate logistic regression and Cox regression analyses were performed to estimate the impact of early surgery on hospital and 1-year mortality after adjustments for other significant covariates. RESULTS: Of the 857 patients with IE complicated by ischemic stroke syndromes, 198 who underwent valve replacement surgery poststroke were available for analysis. Overall, 58 (29.3%) patients underwent early surgical treatment vs 140 (70.7%) patients who underwent late surgical treatment. After adjustment for other risk factors, early surgery was not significantly associated with increased in-hospital mortality rates (odds ratio, 2.308; 95% confidence interval [CI], .942-5.652). Overall, probability of death after 1-year follow-up did not differ between 2 treatment groups (27.1% in early surgery and 19.2% in late surgery group, P = .328; adjusted hazard ratio, 1.138; 95% CI, .802-1.650). CONCLUSIONS: There is no apparent survival benefit in delaying surgery when indicated in IE patients after ischemic stroke. Further observational analyses that include detailed pre- and postoperative clinical neurologic findings and advanced imaging data (eg, ischemic stroke size), may allow for more refined recommendations on the optimal timing of valvular surgery in patients with IE and recent stroke syndromes.

Résumé : International audience
BACKGROUND: There is no recommendation for treating pulmonary hypertension (PH) when associated with chronic obstructive pulmonary disease (COPD). OBJECTIVE: To evaluate the effect of PH-specific therapy in patients with COPD. METHODS: All successive patients with severe PH [mean pulmonary arterial pressure (mPAP) ≥35 mm Hg] and COPD, who received specific PH medication and who underwent right heart catheterization at baseline and after 3-12 months of treatment, were analyzed from a prospective database. RESULTS: Twenty-six patients were included with a median follow-up of 14 months. Mean forced expiratory volume in 1 s was 57 ± 20% of predicted, and mean forced expiratory volume in 1 s/forced vital capacity was 47 ± 12%. Dyspnea was New York Health Association classification stage (NYHA) II in 15%, NYHA III in 81% and NYHA IV in 4%. First-line treatments were endothelin receptor antagonists in 11 patients, phosphodiesterase-5 inhibitors in 11 patients, calcium blocker in 1 patient, combination therapy in 3 patients including 2 with a prostanoid. After 6 ± 3 months, pulmonary vascular resistance decreased from 8.5 ± 3 to 6.6 ± 2 Wood units (p extless 0.001), with significant improvement of cardiac index from 2.44 ± 0.43 to 2.68 ± 0.63 liters × min × m-2 (p = 0.015) and mPAP from 48 ± 9 to 42 ± 10 mm Hg (p = 0.008). There was no significant difference in dyspnea, 6-min walking distance, echocardiographic parameters or N-terminal pro-brain natriuretic peptide levels. There was no significant difference in arterial oxygen saturation after 3-12 months of treatment. CONCLUSIONS: Specific PH medications may improve hemodynamic parameters in COPD patients with severe PH. Appropriate prospective randomized studies are needed to evaluate the potential long-term clinical benefit of treatment

Résumé : International audience
Introduction: The value and challenges of long-term prophylaxis (LTP) in adolescents and young adults need further characterisation.Aim: To determine the proportions of adolescents and young adults with severe or moderately severe haemophilia in France under LTP and treatment on demand (OD).Methods: Patients 15 to 25 years old with haemophilia A or B, factor VIII/IX ≤ 2% and no current inhibitor could be included if they had been under factor VIII/IX treatment at least 12 months and kept a treatment and bleeding diary.Results: LTP was administered to 169/212 patients (79.7%) and OD treatment to 40/212 patients (18.9%). The most frequent reasons for initiating LTP were joint bleeding, target joints and frequent bleeds; whereas OD treatment was most often selected on the basis of mild bleeding phenotype or because of constraints on LTP. The mean annual bleed rate (ABR) in the OD group (6.33) was higher than in the LTP group (3.07, p < 0.001). Mean ABR did not differ significantly between age strata (15–18, > 18–21 and > 21–25 years), but was significantly higher for patients with severe haemophilia (4.02) as compared to those with moderate haemophilia (1.97, p = 0.002). No significant difference was observed in mean ABR for joint bleeds between the LTP and OD groups. Physician reported LTP compliance was good or excellent in 97.0% of patients.Conclusion: LTP is the predominant factor VIII/IX treatment among adolescents and young adults with severe or moderately severe haemophilia in France. LTP was associated with low ABR and high compliance. © 2017 The Authors

Résumé : International audience
Environmental health risk assessment is commonly used in France for risk management purposes. The Methodology section of the "Société française de santé environnement" (French Society for Environmental Health) seeks to improve the utility and implementation of risk assessment in France. An initial operational objective is to make a list of short-, intermediate- and long-term improvements. This inventory is based in part on the experience and expertise of society members in this area and in part on their analysis of "Science and Decisions: Advancing Risk Assessment" (National Research Council 2009). In this paper, the Society recommends modifications in the indications for and use of risk assessments, during each of the four stages of the process: hazard identification and dose-response assessment, exposure assessment, risk characterization, and results interpretation. Some may be implemented now, while others need consensus building or research because of gaps in knowledge. Environmental health risk assessment must be understood as a decision tool for risk management in situations of uncertainly. Thus, appropriate linkage is required between decision making and assessment, and between the methods and the expected results.
L'évaluation des risques sanitaires est fréquemment utilisée en France dans les processus de décision en santé environnementale. La section " Méthodologie d'évaluation des risques sanitaires " de la Société française de santé environnement (SFSE) s'est donnée pour objectif de proposer des éléments de réflexion et des outils méthodologiques en vue d'améliorer l'utilité et les pratiques de l'évaluation des risques sanitaires. Un premier objectif opérationnel est l'inventaire des améliorations possibles à court, moyen et long termes à apporter à la démarche et à son utilisation. Ce travail s'est fondé, d'une part, sur la pratique et l'expertise des membres de la section, et, d'autre part, sur une lecture critique du rapport " Science and Decisions : Advancing Risk Assessment " publié en 2009 par le National Research Council et portant également sur les évolutions de la démarche. Dans cet article, la section restitue les conclusions de cet inventaire critique et propose un certain nombre d'améliorations en termes d'indications et d'utilisations de l'évaluation des risques sanitaires pour chacune des quatre étapes : identification des dangers et relation dose-réponse ; évaluation de l'exposition ; caractérisation des risques ; et interprétation des résultats. Certaines recommandations peuvent être mises en oeuvre immédiatement ; d'autres, en préalable à leur mise en oeuvre, nécessitent un consensus ou encore de la recherche car les connaissances manquent. En conclusion, la section insiste sur le fait que l'évaluation des risques sanitaires doit être comprise comme une aide à la décision en situation d'incertitude ; l'articulation entre le contexte décisionnel et l'évaluation, sa méthodologie et les résultats attendus est donc primordiale.

Résumé : [b]Background[/b]: [i]Amblyomma variegatum[/i] and [i]A. hebraeum[/i] are two ticks of veterinary and human health importance in south-east Africa. In Zimbabwe they occupy parapatric (marginally overlapping and juxtaposed) distributions. Understanding the mechanisms behind this parapatry is essential for predicting the spatio-temporal dynamics of Amblyomma spp. and the impacts of associated diseases. It has been hypothesized that exclusive competition between these species results from competition at the levels of male signal reception (attraction-aggregation-attachment pheromones) or sexual competition for mates. This hypothesis predicts that the parapatry described in Zimbabwe could also be present in other countries in the region. [br/][b]Methods[/b]: To explore this competitive exclusion hypothesis we conducted field surveys at the two species' range limits in Mozambique to identify areas of sympatry (overlapping areas) and to study potential interactions (communicative and reproductive interference effects) in those areas. At sympatric sites, hetero-specific mating pairs were collected and inter-specific attractiveness/repellent effects acting at long and short distances were assessed by analyzing species co-occurrences on co-infested herds and co-infested hosts.[br/] [b]Results[/b]: Co-occurrences of both species at sampling sites were infrequent and localized in areas where both tick and host densities were low. At sympatric sites, high percentages of individuals of both species shared attachment sites on hosts and inter-specific mating rates were high. Although cross-mating rates were not significantly different for[i] A. variegatum[/i] and [i]A. hebraeum[/i] females, attraction towards hetero-specific males was greater for [i]A. hebraeum[/i] females than for A. variegatum females and we observed small asymmetrical repellent effects between males at attachment sites.[br/][b]Conclusions[/b]: Our observations suggest near-symmetrical reproductive interference between [i]A. variegatum[/i] and [i]A. hebraeum[/i], despite between-species differences in the strength of reproductive isolation barriers acting at the aggregation, fixation and partner contact levels. Theoretical models predict that sexual competition coupled with hybrid inviability, greatly reduces the probability of one species becoming established in an otherwise suitable location when the other species is already established. This mechanism can explain why the parapatric boundary in Mozambique has formed within an area of low tick densities and relatively infrequent host-mediated dispersal events.

Résumé : No matter which production system is considered (5% milk farms, 95% meatfarms), the Salers breed of cattle carries a strong image. Our work aims at showing that the development of the main territory in which the breed is found may rely on specific and identified products afforded by the breed. Multidisciplinary research (animal science, economics, food quality) and different methods (surveys, follow-up, and experimentation) were implemented. The experiments focused on the control of various types of production (milk, carcasses) and on a detailed description of the products (meat, cheese), given the attributes and the special behaviour of the animals. A before-weaning feeding approach favouring milk and forage later proves more efficient for finishing the young Salers male (15 months). The meat from these young bulls is clear, classified as mid-range quality, and can be sold in supermarkets. Parallel observations were made on farms and specific protein markers of juiciness were identified. Milk from Salers cows differs from that of Holstein especially in the nature of the fatty acids. Calf suckling before milking reinforces the differences. Cheeses made with raw milk from the breed differ in their textures and flavours. The cow must however be milked with her calf and the level of labour required impedes economic valorisation of the breed. Consumer surveys have confirmed the strong image of the breed that has a good potential for commercial development. Willingness to pay for identified products, however, is stronger for cheese (up to 30%) than for meat (up to 10%). Recognized qualities of products identified as issued from Salers cattle and originality in production systems can bring significant gains to various local actors, which can be considered as territorial rents.
La race bovine Salers bénéficie d’une image forte et reconnue, indépendante du système de production, laitier pour 5 % des élevages, ou allaitant pour 95 %. Pour autant le développement du « berceau de la race » peut-il s’appuyer sur les combinaisons de productions spécifiques et identifiées qu’autorise cette race ? Des recherches multidisciplinaires (zootechnie, économie, qualité des aliments) et des méthodes d’investigation variées (enquêtes, suivis, expérimentation) ont été mises en œuvre pour répondre à cette question. Les expérimentations ont porté sur la maîtrise des itinéraires de production (lait, carcasses) et la connaissance fine des produits (fromages, viandes), compte tenu des aptitudes et du comportement de la race. Une conduite alimentaire privilégiant le lait et les fourrages avant sevrage est ainsi plus efficace pour la production d’un jeune bovin Salers (15 mois). La viande de ces taurillons est claire, classée en gamme intermédiaire, mais peut se valoriser en grande et moyenne distribution. Le lait des vaches Salers diffère de celui des vaches Holstein surtout par la nature de ses acides gras. La tétée d’amorçage du veau spécifique de la race et difficile à supprimer, renforce les différences de composition. Les fromages fabriqués avec ce lait traité à l’état cru diffèrent par leurs textures et arômes. Une filière laitière pérenne pourrait bien valoriser ces différences mais la pénibilité de la traite faite obligatoirement en présence du veau reste un obstacle. Des enquêtes auprès de consommateurs ont confirmé la forte image de la race vectrice de valorisation économique. Leur consentement à payer pour des produits identifiés est cependant plus fort pour le fromage (jusqu’à 30 %) que pour la viande (jusqu’à 10 %). Les qualités reconnues des produits identifiés comme issus de vaches Salers et l’originalité des systèmes de production peuvent apporter des plus-values significatives aux divers acteurs locaux, ce qui peut correspondre à une forme de rente territoriale.
