The incidence of invasive fungal infections has increased in recent years among transplant patients, with Trichosporon inkin being a rare but relevant etiological agent. This study examines the experience of our multidisciplinary lung transplant unit in the diagnosis and treatment of 6 cases of T. inkin infection in transplant patients from 2016 to 2023.

Shortened telomere length (STL) is associated with increased rates of interstitial lung diseases, malignancy, hematological disorders, and immunosuppressive treatment toxicities. In this single-center retrospective study, we aim to determine whether patients with interstitial lung diseases who have STL, as determined by quantitative PCR of buccal epithelial cells, exhibit worse post-transplant outcomes compared to recipients with normal telomere length. In our series of 26 patients, STL was associated with a higher incidence of chronic kidney disease following lung transplantation (100% vs 55%, P = .

Unlabelled: Our study aims to evaluate the effect of everolimus treatment on lung function in lung transplant (LT) patients with established chronic lung allograft dysfunction (CLAD).

Methods: This retrospective study included LT patients in two reference LT units who started everolimus therapy to treat CLAD from October 2008 to October 2016. We assessed the variation in the maximum forced expiratory volume in the first second (FEV) before and after the treatment.

Introduction And Objectives: Chronic thromboembolic disease refers to the presence of chronic thrombotic pulmonary vascular thrombosis without pulmonary hypertension (PH) at rest but with exercise limitation after pulmonary embolism (PE). Our aim was to evaluate the hemodynamic response to exercise in these patients and its correlation with the values reached in cardiopulmonary exercise testing.

Methods: We included symptomatic patients with persistent pulmonary thrombosis after PE.

Background: SARS-CoV2 infection causes high morbidity and mortality in lung transplant (LT) recipients. Vaccination with messenger RNA vaccines has been shown to play a key role in controlling the severity of infection in the general population. The aim of our study is to analyze whether vaccination with 2 doses of SARS-Cov2 provides immunity in LT recipients.

Background: The primary aim of this study was to analyze the survival of patients undergoing lung transplant (LT) with cytomegalovirus (CMV)-positive serologies at the time of transplantation, according to the presence of CMV events and according to the severity of these events. The secondary objective was to assess whether there are differences in the incidence of chronic lung allograft dysfunction (CLAD) according to the presence of these events.

Methods: This was an observational, single-center, retrospective study.

Background: Chronic lung allograft dysfunction (CLAD) is the leading cause of mortality after the first year of transplantation and treatments can have little impact on CLAD progression in some cases. The objective of this study was to evaluate the effectiveness and safety of antithymocyte globulin (ATG) in lung transplant recipients with CLAD.

Methods: We reviewed all patients from our center that had undergone a lung transplant between 2008 and 2019 and selected those with CLAD who were treated with ATG.

Antisynthetase Syndrome (ASS) is a subset of idiopathic inflammatory myopathies characterised by specific clinical features such as interstitial lung disease (ILD), fever, myositis, Raynaud's phenomenon, cutaneous involvement and arthritis related to the presence of anti-aminoacyl-tRNA-synthetase (anti-ARS) autoantibodies. Moreover, Pulmonary arterial hypertension (PAH) is a life-threatening complication associated with connective tissue diseases mainly systemic sclerosis (SSc-PAH). It has been suggested that PAH can complicate ASS patients but little is known about the prevalence and risk factors to develop this complication.

Article Synopsis
  • - Pulmonary arterial hypertension (PAH) is a serious condition with high morbidity and mortality, characterized by increased pressure in the lungs and right heart dysfunction; this study aimed to analyze patient outcomes and prognostic factors at a national center over 30 years.
  • - The study included 379 PAH patients from 1984 to 2014, revealing trends like an increase in complex disease types and a significant rise in upfront combination therapy over the years, indicating improved treatment approaches.
  • - Key prognostic factors identified included age, sex, etiology, and various clinical variables, with a median survival of 9 years and survival rates decreasing over time; the findings stress the need for adaptable, multidisciplinary PAH care.
