Filter by:Pulmonary rehabilitation is effective in the treatment of pulmonary hypertension (PH). However, the beneficial effects of such intervention have been seen to disappear over time in other chronic diseases. The objective of the project is to evaluate the efficacy of an urban exercise program after a rehabilitation program and to identify possible determinants of sustainability of the effect, both in patients and in a murine experimental model. Methodology: 1) Study in humans: randomized study (urban training) in 80 patients with PH. The main variable is the improvement in physical activity measured by accelerometry at 12 months. Improvements in bioimpedance and aerobic capacity will be analysed as secondary variables, as well as possible determinants of vascular function that guarantee the sustainability of the effect (pulse wave velocity, endothelial function, metabolic profile and other plasma biomarkers), and all of them will be correlated with the evolution of the disease (admission due to clinical deterioration). 2) Studies in a murine experimental model: Mice with pulmonary hypertension induced by the administration of SU5416 (sugen) and exposure to hypoxia for 3 weeks will be studied after a three-week rehabilitation program. Half of them will exercise 1-2 days a week for 4 more weeks. At the end of the program, the right ventricular pressure will be measured and subsequently the animals will be sacrificed. Morphometric studies will be performed on lung, cardiac and muscular tissue. Vascular endothelial function and autophagy will be also measured. The differences in these variables between the different experimental groups will be analysed.
Patients with pulmonary hypertension underwent (routine) Holter ECG and were screened for (malignant) arrhyhtmias. Results of Holter ECGs were correlated with clinicial and technical data (echocardiography and right heart catheterization).
ADAMTSL4 (A disintegrin and metalloproteinase with thrombospondin motifs like) is a member of the ADAMTSL family. ADAMTSL4 is one of the family of 7 ADAMTS-Like proteins, themselves part of the Thrombospondin type 1 repeat (TSR) superfamily of proteins. These 7 proteins are divided into two distinct clades, of which ADAMTSL4 and ADAMTS-Like 6 form part of one clade, differing from ADAMTS-Like 1, ADAMTS-Like 3 and ADAMTS-Like 7 by lacking immunoglobulin repeat regions. ADAMTSL4 is widely expressed in brain, colon, heart, kidney, liver, lung, pancreas and spleen, yet, its precise role is unclear. in addition, ADAMTSL4 protein high expression to the medial layer of the arterial wall, and medial vascular smooth muscle cells specifically.
Heart failure (HF) is a syndrome, resulting from structural or functional impairment of ventricular filling or ejection of blood. Effective HF management depends on accurate and rapid diagnosis requiring assessment of symptoms and physical signs in combination with advanced and expensive imaging tools. However, several challenges arise from the traditional symptom-based diagnosis because co-morbidities of HF have similar presentations. This implies the need for a deeper knowledge of mechanistic links among genetic and epigenetic events governing the pathophysiology of HF leading to a novel molecular-based system to differentiate HF phenotypes. Now, it is emerging that the pathophysiology of HFpEF and HFrEF is different, it provides an opportunity to identify biomarker candidates that could aid in HF diagnosis and stratification between these two forms of the disease. The aim of PRESMET project is to perform liquid biopsy strategies to identify novel putative non-invasive epigenetic-sensitive biomarkers that could be used either alone or in combination with established diagnostic tests, such as natriuretic peptide, to help differentiate HFpEF from HFrEF. The Investigators will perform DNA methylation analysis on CD4+ T cells isolated from patients versus controls. Remarkably, big data generated from NGS tools will be analyzed by advanced network-oriented algorithms. Our results may provide a useful clinical roadmap in order to improve precision medicine and personalized therapy of HF.
Hypersensitivity pneumonitis (HP) is a complex immune mediated disorders caused by repeated inhalation of and sensitization to wide range of antigens including organic particles and chemical compounds, leading to exaggerated immuneresponse. Hypersenstivity pneumonitis is a common form of diffuse parenchymal lung diseases in Egypt .Pulmonary hypertension has been found as a complication of a number of diseases affecting the lung interstitium, including hypersensitivity pneumonitis, with subsequent affection of the life expectancy Rationale of the study: to find predictors for the development of pulmonary hypertension in patients with hypersensitivity pneumonitis
Our study aims to investigate the changes in muscle strength and muscle mass in PAH patients compared to healthy individuals and determine its effects on prognosis. Further categorization of PAH patients based on their NYHA class will help determine if their handgrip strength decreases while progressing from NYHA class 1 to 4. This in turn allows us to examine if the handgrip test can be considered as an alternative to a 6-minute walking test (6MWT). The Jamar Hydraulic Hand Dynamometer device in our hospital is used for measuring the handgrip strength test. The data of the included subjects in this study are obtained and recorded from the existing files. Also, the handgrip strength test data will be recorded after the investigation
Children with pulmonary hypertension (PH) engage in less physical activity than their peers. This is a concern since adult data support exercise as a non-pharmacologic treatment for PH. Despite adult data, therapeutic exercise has not been widely adopted in pediatric PH. Investigators have previously demonstrated that children with PH have less skeletal muscle mass in association with worse exercise performance. Interventions to increase physical activity and skeletal muscle mass may improve exercise performance and quality of life in children with PH. This study will use wearable activity monitoring devices to promote physical activity in a 16-week pilot intervention in children and teenager with PH.
This is a FIH, double-blind, placebo-controlled, within-group randomised, trial designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of single and multiple ascending oral doses of compound 106 (C106) in healthy females of non-childbearing potential and healthy males. The trial will be conducted in 2 parts: Part A, single ascending dose (SAD) including a food interaction cohort: safety, tolerability, and PK in healthy males and healthy females of non-childbearing potential receiving single ascending doses of C106. Part B, multiple ascending dose (MAD): safety, tolerability, and PK in healthy males and healthy females of non-childbearing potential receiving twice daily multiple ascending doses of C106 for 8 days.
Recruit at least 700 PH patients, follow up every 6 months based on a computerized follow-up system. Primary outcomes are adverse drug events and all-cause death.
