BACKGROUND AND AIMS: The main stages of cirrhosis (compensated and decompensated) have been substaged based on clinical, endoscopic, and portal pressure (determined by the hepatic venous pressure gradient, HVPG) features. Vasodilatation leading to a hyperdynamic circulatory state is central in the development of a late decompensated stage with inflammation being currently considered a key driver. We aimed to assess hepatic/systemic hemodynamics and inflammation (by C reactive protein, CRP) among the different substages of cirrhosis and to investigate their interrelationship and prognostic relevance...

BACKGROUND: Cell based therapy has been heralded as a novel, promising therapeutic strategy for cardiovascular diseases including pulmonary arterial hypertension (PAH). However, the low survival rate after transplantation due to cell death via anoikis is a major obstacle in stem cell therapy. Cells adhesion via Integrin alpha5beta1 (ITGA5B1) has a tendency to exert higher maximum forces. The present study aimed to evaluate the potential protective effect of ITGA5B1 on rat bone marrow mesenchymal stem cells (rBMSCs) from anoikis...

Feasibility, tolerance, and safety of intravenous infusions of allogeneic mesenchymal stem cell (MSC) therapy in lung transplant recipients with bronchiolitis obliterans syndrome (BOS) are not well established. MSCs were manufactured, cryopreserved, transported to our facility, thawed, and infused into nine recipients with moderate BOS (average drop in forced expiratory volume in 1 second was 56.8% ± 3.2% from post-transplant peak) who were refractory to standard therapy and not candidates for retransplant...

The overall survival of children with solid tumors has shown a substantial increase in the past decades due to progress in all of the disciplines involved in the treatment. The poor prognosis for advanced stages of disease and the morbidity related to therapeutic procedures are still a challenge. Innovations in the surgical treatment of solid tumors can contribute to increase the survival rate of affected children and to decrease the treatment-related morbidity. Considering these aspects, the successful implementation of innovations is described based on four examples...

To enhance the understanding of the left coronary artery originating from the pulmonary artery, we report a case of sudden cardiac arrest during exercise. After successful cardiopulmonary resuscitation, the patient underwent echocardiography and selective coronary angiography, and the disease was firmly diagnosed. Consequently, a thoracic surgery was performed. During the operation, the left coronary artery was transplanted to the root of the aorta and the pulmonary valve and artery were reconstructed. Finally, the surgery was successful...

Lung transplantation is a definitive treatment for select patients with end-stage pulmonary disease. Following transplantation, the reported rate of lung cancer is between 1-9% and is associated with a variety of risk factors, including smoking history and chronic immunosuppression. The majority of post-transplant lung cancer reported in the literature is histologically classified as non-small cell lung carcinoma (NSCLC). We report a unique case of early stage small cell lung carcinoma (SCLC) identified in the native lung following single lung transplantation...

Lung transplantation nowadays is a well-accepted and routine treatment for well selected patients with terminal respiratory disease. However, it took several decades of experimental studies and clinical attempts to reach this success. In this paper, we describe the early experimental activity from the mid-forties until the early sixties. The first clinical attempt in humans was reported by Hardy and Webb in 1963 followed by others with short survival only except for one case by Derom et al. who lived for 10 months...

Hepatic hydrothorax (HH) is a pleural effusion that develops in a patient with cirrhosis and portal hypertension in the absence of cardiopulmonary disease. Although the development of HH remains incompletely understood, the most acceptable explanation is that the pleural effusion is a result of a direct passage of ascitic fluid into the pleural cavity through a defect in the diaphragm due to the raised abdominal pressure and the negative pressure within the pleural space. Patients with HH can be asymptomatic or present with pulmonary symptoms such as shortness of breath, cough, hypoxemia, or respiratory failure associated with large pleural effusions...

The authors report the first case involving a patient with Wiskott-Aldrich syndrome who underwent single living-donor lobar lung transplantation after haematopoietic stem cell transplantation. Haematopoietic stem cell transplantation was performed at 1 year of age; however, he developed severe pulmonary complications. Although lung transplantation is generally contraindicated in patients with immunodeficiency disease, the patient was able to undergo living-donor lobar lung transplantation because his immunodeficiency and thrombocytopenia were well controlled as a result of haematopoietic stem cell transplantation...

Lung transplantation (LuTx) is an important treatment for a selected group of patients in the terminal stage of a number of lung diseases, which can bring them a significant improvement in quality of life and long-term survival. Nowadays a perioperative period is not significant limitation for patient survival due to the development of transplant surgery, but the period of months to years after LuTx is crucial for survival. The post-transplant period is very complicated for LuTx patients due to a special treatment regimen, special medication, especially immunosuppressive drugs and the possibility of many complications, whether early or late or acute or chronic...

Hepatic veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) is an unpredictable condition associated with endothelial-cell damage due to conditioning for hematopoietic stem-cell transplantation (HSCT) or chemotherapy without HSCT. Mortality in patients with VOD/SOS and multi-organ dysfunction (MOD) may be >80%. Areas covered: Defibrotide is the only approved drug for the treatment of severe hepatic VOD/SOS after HSCT in the European Union and hepatic VOD/SOS with renal or pulmonary dysfunction in the United States...

OBJECTIVES: Left ventricular dysfunction after pulmonary endarterectomy is well described. Left ventricular failure has only been described after lung transplantation for pulmonary arterial hypertension (PAH). We sought to identify factors that contribute to this failure and hypothesized that atrial septostomy before transplantation could prevent this complication. METHODS: From our database, all bilateral lung transplants for PAH (n = 24) and all pulmonary endarterectomies, with a minimal reduction of 800 dyn⋅s⋅cm-5 (n = 27), were selected...

Accumulating evidence shows a causative role for the bone marrow (BM) in the genesis and progression of pulmonary hypertension (PH). Engraftment of BM hematopoietic stem cells from PH patients to mice reproduces the cardiopulmonary pathology of PH. However, it is unknown whether healthy BM can prevent the development of right heart disease. Caveolin-1-deficient (CAV-1 KO) mice develop cardiopulmonary disease with manifestations resembling PH, including elevated right ventricular (RV) systolic pressure (RVSP), RV hypertrophy, and pulmonary endothelial proliferative disease...

Outcomes of hematopoietic stem cell transplantation (HSCT) have markedly improved over the past 2 decades, underscoring a need to better understand the long-term health effects of this intensive treatment modality. We describe the burden of chronic medical conditions and frail health among St. Jude Lifetime Cohort Study participants treated for childhood hematologic malignancies with HSCT (n = 112) or with conventional therapy (n = 1106). Chronic conditions and frail health were ascertained clinically and classified according to a modified version of the Common Terminology Criteria for Adverse Events (version 4...

Several endothelin receptor antagonists (ERAs) that were developed for the treatment of pulmonary arterial hypertension (PAH), including bosentan and sitaxentan, have been linked to clinically significant hepatocellular injury, as well as liver failure. We describe the first case of fulminant hepatitis to be reported in association with the ERA macitentan. This case was recently identified within the United States Food and Drug Administration Adverse Event Reporting System (FAERS) and and describes liver transplantation occuring 13 months following macitentan initiation in a young patient (23-years old) with idiopathic PAH New York Heart Association (NYHA) functional class III...
