Description, clinical impact and early outcome of S. maltophilia respiratory tract infections after lung transplantation, A retrospective observational study.

Background And Research Question: S. maltophilia infections are associated with significant morbidity and mortality. Little is known regarding its presentation, management, and outcome in lung transplant recipients.

Thirty years of surgical management of pediatric pulmonary hypertension: Mid-term outcomes following reverse Potts shunt and transplantation.

Background: Reverse Potts shunt (RPS) and lung or heart-lung transplantation are life-extending surgical interventions for pediatric patients with severe pulmonary arterial hypertension (PAH). Robust criteria for identifying patients who will benefit from these procedures remain elusive. Based on 30 years of experience, we sought to refine the surgical indications.

A Patient-Centered Model of Fast-Track Lung Cancer Diagnosis.

Introduction: Despite the increasing importance of digital resources in modern life over the past decades, little is known about the impact of internet-based solutions on patient's health. We aimed to study the potential benefit of a digital platform helping patients to deal with abnormal chest CT scan revealing possible lung cancer.

Methods: We set up a fast-track lung cancer diagnosis pathway through a secure online platform.

Risk stratification in patients with pulmonary arterial hypertension at the time of listing for lung transplantation.

Background: It is unknown whether pulmonary arterial hypertension (PAH) risk stratification instruments could be helpful to support the decision to list a patient for lung transplantation (LT). Our aim was to evaluate contemporary risk assessment tools in a cohort of PAH patients listed for LT.

Methods: Consecutive PAH patients (without pulmonary veno-occlusive disease or unrepaired congenital heart disease) listed for LT at the French Pulmonary Hypertension Reference Center between January 2006 and December 2018 were included.

Use of anti-CMV immunoglobulins in lung transplant recipients: The French experience.

Rational: Pending the authorization of new anti-CMV drugs with fewer adverse effects, exploring the possibilities offered by CMV immunoglobulins (CMVIG) seems necessary. In France, access to CMVIG requires official authorization by the national Health authority and is restricted to second line rescue therapy for CMV infection/disease. The aim of this multicenter retrospective study is to describe the indications and clinical situations that justified its use in France.

Lung and heart-lung transplantation for children with PAH: Dramatic benefits from the implementation of a high-priority allocation program in France.

Purpose: Pulmonary arterial hypertension (PAH) is rare but remains fatal in infants and children despite the advance of targeted therapies. Lung transplantation (LTx), first performed in pediatric patients in the 1980s, is, with the Potts shunt, the only potentially life-extending option in patients with end-stage PAH but is possible only in tightly selected patients. Size-matching challenges severely restrict the donor organ pool, resulting-together with peculiarities of PAH in infants-in high waitlist mortality.

Transplantation for pulmonary arterial hypertension with congenital heart disease: Impact on outcomes of the current therapeutic approach including a high-priority allocation program.

Patients with end-stage pulmonary arterial hypertension due to congenital heart disease have limited access to heart-lung transplantation or double-lung transplantation. We aimed to assess the effects of a high-priority allocation program established in France in 2007. We conducted a retrospective study to compare waitlist and posttransplantation outcomes before versus after implementation of the high-priority allocation program.

Lung transplantation for idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is characterized by relentlessly progressive lung function impairment that is consistently fatal in the absence of lung transplantation, as no curative pharmacological treatment exists. The pace of progression varies across patients, and acute life-threatening exacerbations occur unpredictably, causing further sharp drops in lung function. Recently introduced antifibrotic agents slow the pace of disease progression and may improve survival but fail to stop the fibrotic process.

[Extracorporeal life support and heart-lung transplant in children].

Extracorporeal life support and heart and/or lung transplant are the last resort in children with end-stage cardiac and/or pulmonary failure and short-term life threaten. Currently, circulatory support is used as a bridge to recovery or as a bridge to transplant but not as a destination therapy. The Excor Berlin Heart is the long-lasting external pneumatic ventricular assist system that is currently available from infancy to adulthood.

Central versus peripheral cannulation of extracorporeal membrane oxygenation support during double lung transplant for pulmonary hypertension.

Objectives: Extracorporeal membrane oxygenation (ECMO) has become the standard of cardiopulmonary support during a sequential double lung transplant for pulmonary hypertension. Whether central or peripheral cannulation is the best strategy for these patients remains unknown. Our goal was to determine which is the best strategy by comparing 2 populations of patients.

De-novo donor-specific anti-HLA antibodies 30 days after lung transplantation are associated with a worse outcome.

Background: The impact of de-novo donor-specific anti-HLA antibodies (DSA) on patient and graft survival after lung transplantation remains controversial. We analyzed DSA that developed at Day 7 and Month (M) 1, M3, M6 and M12 after lung transplantation and evaluated their impact on chronic lung allograft dysfunction (CLAD) development and survival.

Methods: One hundred thirty-four patients who underwent lung transplantation at our institution between November 2007 and August 2013 were included in this study.

Nonspecific interstitial pneumonia: survival is influenced by the underlying cause.

Idiopathic, nonspecific interstitial pneumonia (NSIP) is most often associated with various clinical disorders, including connective tissue diseases (CTDs) and chronic hypersensitivity pneumonitis (cHP). Emerging evidence also suggests that "idiopathic" NSIP may be the lung manifestation of undifferentiated CTD (UCTD). However, whether or not NSIP outcome is influenced by the underlying cause remains uncertain.

Prognostic relevance of histological variants in nonspecific interstitial pneumonia.

Aims: Although histological non-specific interstitial pneumonia (NSIP) is concisely defined, overlap with other patterns is described. While most frequently idiopathic, NSIP is seen in various clinical contexts such as connective tissue diseases (CTDs) and chronic hypersensitivity pneumonitis (cHP). This study was designed to determine if NSIP could be separated into subgroups based on minor histological features and to correlate these subgroups with clinical associations and survival.

Efficacy of rituximab in systemic manifestations of primary Sjogren's syndrome: results in 78 patients of the AutoImmune and Rituximab registry.

Objectives: To evaluate the efficacy and safety of rituximab in patients with primary Sjögren's syndrome (pSS).

Methods: The AutoImmune and Rituximab registry has included 86 patients with pSS treated with rituximab, prospectivey followed up every 6 months for 5 years.

Results: Seventy-eight patients with pSS (11 men, 67 women), who already had at least one follow-up visit, were analysed.

Active chronic sarcoidosis is characterized by increased transitional blood B cells, increased IL-10-producing regulatory B cells and high BAFF levels.

Background: Sarcoidosis is a multisystemic disease of unknown etiology characterized by a disproportionate Th1 granulomatous immune response in the organs involved. Plasmatic hypergammaglobulinemia and B cell accumulation in granulomatous lesions suggest the possible role of humoral immune responses in the pathogenesis of sarcoidosis. The purpose of this study is to describe B cell peripheral compartment in sarcoidosis.

Pulmonary Langerhans cell histiocytosis-associated pulmonary hypertension: clinical characteristics and impact of pulmonary arterial hypertension therapies.

Background: Precapillary pulmonary hypertension (PH) is a complication of pulmonary Langerhans cell histiocytosis (PLCH) associated with increased mortality. However, outcomes and efficacy of pulmonary arterial hypertension (PAH) therapies in patients with PH complicating PLCH(PLCH-PH) remain unknown.

Methods: Consecutive patients with PLCH with PH confirmed by right-sided heart catheterization were included in the study.

The spectrum of lung involvement in collagen vascular-like diseases following allogeneic hematopoietic stem cell transplantation: report of 6 cases and review of the literature.

Multisystem autoimmune diseases occurring after allogeneic hematopoietic stem cell transplantation are infrequent, late-onset manifestations that resemble well-defined collagen vascular disorders. Because the lung is frequently involved in the course of connective tissue disorders, we focused on lung manifestations occurring in autoimmune diseases following allogeneic stem cell transplantation. In the present series, we report 6 patients with systemic lupus erythematous, mixed connective tissue disease, Sjögren syndrome, polymyositis, and ANCA-positive vasculitis who presented with a spectrum of pulmonary manifestations affecting the airways, lung parenchyma, and probably respiratory muscles.

Risk factors for pneumonia in immunocompromised patients with influenza.

Background: Immunocompromised patients with influenza are at higher risk of pneumonia and death. However, risk factors for progression to pneumonia still need evaluation.

Methods: Retrospective study in immunocompromised patients with influenza-related respiratory infections.

[Pulmonary Langerhans cell histiocytosis in adults].

Pulmonary Langerhans-cell histiocytosis in adults is a rare condition of unknown etiology characterized by the accumulation of Langerhans cells organized in granulomas involving the distal bronchioles and destroying their walls. It occurs in young subjects who smoke, with frequency peaking between 20 and 40 years. High-resolution thoracic CT is essential for diagnosis; in typical forms it shows a combination of nodules, cavitary nodules, thick-walled cysts, and thin-walled cysts.
