BACKGROUND: Sickle cell disease (SCD) is a monogenic disease associated with multisystem morbidity. Vasculopathy caused by delicate imbalance between coagulation and endothelial systems plays a pivotal role in disease course. As Protein Z and Endothelin-1 genetic polymorphisms may increase the thrombotic risk, the aim of the current work was to verify the possible impact of Protein Z (PROZ G79A) and Endothelin-1 (EDN1 G5665T) polymorphisms on the clinic-laboratory features of the SCD in a cohort of Egyptian pediatric patients...

INTRODUCTION: The role of Pulmonary and Activation-Regulated Chemokine (PARC) in the physiopathology of Chronic Obstructive Pulmonary Disease (COPD) is not fully understood. The aim of the present study is to analyze the expression of PARC in lung tissue and its relationship with the vascular remodeling of the systemic and pulmonary arteries of COPD subjects. METHODS: To achieve this objective, protein and gene expression experiments, together with ELISA assays, were performed on the lung tissue, intercostal arteries and serum samples from COPD patients, non-obstructed smokers (NOS) and never-smokers (NS)...

Chronic hypoxia induces pulmonary hypertension and vascular remodeling, which are clinically relevant to patients with chronic obstructive pulmonary disease (COPD) associated with a decreased level of nitric oxide (NO). Oxidative stress and inflammation play important roles in the pathophysiological processes in COPD. We examined the hypothesis that daily administration of melatonin (10 mg/kg) mitigates the pulmonary hypertension and vascular remodeling in chronically hypoxic rats. The right ventricular systolic pressure (RVSP) and the thickness of pulmonary arteriolar wall were measured from normoxic control, vehicle- and melatonin-treated hypoxic rats exposed to 10% O₂ for 14 days...

OBJECTIVE: To investigate the expression of Toll-like receptor 4 (TLR4) and matrix metalloproteinase-9 (MMP-9) in patients with chronic obstructive pulmonary disease (COPD) and their clinical significance. PATIENTS AND METHODS: Paracancerous tissues from 48 patients with lung squamous cell carcinoma harvested during pulmonary lobectomy were studied. Twenty-four cases of COPD were chosen as the observation group and 24 cases of non-COPD as the control group. The degree of lung inflammation was observed; the ratio of the thickness of the wall to the external diameter of the pulmonary arterioles (WT%), and the ratio of the area of the wall to that of the pulmonary arterioles (WA%) were calculated...

BACKGROUND: Tobacco-induced pulmonary vascular disease is partly driven by endothelial dysfunction. The Sonic hedgehog (SHH) pathway is involved in vascular physiology. We sought to establish whether the SHH pathway has a role in pulmonary endothelial dysfunction in smokers. METHODS: The ex vivo endothelium-dependent relaxation of pulmonary artery rings in response to acetylcholine (Ach) was compared in 34 current or ex-smokers and 8 never-smokers. The results were expressed as a percentage of the contraction with phenylephrine...

OBJECTIVE: Patients with chronic obstructive pulmonary disease (COPD) often have abnormal ECGs. Our aim was to separate the effects on ECG by airway obstruction, emphysema and right ventricular (RV) afterload in patients with COPD. METHODS: A cross-sectional study was performed on 101 patients with COPD without left heart disease and 32 healthy age-matched controls. Body mass index (BMI) was measured, and pulmonary function tests, ECG, echocardiography and right heart catheterisation (only patients) were performed...

Over the past decade, there has been a major shift in chemotherapy from non-specific cytotoxic drugs to molecular targeted drug therapies. As more molecular targeted therapies are developed, new types of cardiovascular toxicities induced by targeted therapies are a growing problem. Cardiotoxicity induced by the human epidermal growth factor receptor-2 inhibitor trastuzumab manifests as decreased left ventricular ejection fraction. In contrast to anthracycline treatment, most cardiac events occur during trastuzumab treatment, but are reversed quickly when treatment is interrupted and cardiac intervention is established...

Background: Pulmonary arterial hypertension (PAH) is a rapidly degenerating and devastating disease of increased pulmonary vessel resistance leading to right heart failure. Palliative modalities remain limited despite recent endeavors to investigate the mechanisms underlying increased pulmonary vascular resistance, i.e. aberrant vascular remodeling and occlusion. However, little is known of the molecular mechanisms responsible for endothelial proliferation, a root cause of PAH-associated vascular remodeling...

Systemic sclerosis (SSc) is an autoimmune disease characterized by vascular dysfunction and excessive fibrosis, involving internal organs including the heart. The estimated prevalence of cardiac involvement in SSc is high and remains subclinical until the late stages. It is either primary, related to myocardial inflammation and fibrosis, or secondary, due to pulmonary arterial hypertension (SSc-PAH) or systemic hypertension, in those patients with renal involvement. Cardiovascular magnetic resonance (CMR) is a useful tool for the early assessment of cardiac involvement in SSc...

Astragalus polysaccharides (APS) have been shown to possess a variety of biological activities including anti-oxidant and anti-inflammation functions in a number of diseases. However, their function in pulmonary arterial hypertension (PAH) is still unknown. Rats received APS (200[Formula: see text]mg/kg once two days) for 2 weeks after being injected with monocrotaline (MCT; 60[Formula: see text]mg/kg). The pulmonary hemodynamic index, right ventricular hypertrophy, and lung morphological features of the rat models were examined, as well as the NO/eNOS ratio of wet lung and dry lung weight and MPO...

OBJECTIVE: The pulmonary vascular targeted treatment for systemic lupus erythematosus-associated pulmonary arterial hypertension is similar to other connective tissue disease-associated pulmonary arterial hypertension. In addition, there also appears to be a role for immunosuppression in the overall management. However, the optimal immunosuppressive regimen and what patients will respond to treatments are currently not clearly elucidated given the lack of randomized controlled trials on the subject...

BACKGROUND AND OBJECTIVE: A dilated pulmonary artery (PA) is a common finding in patients with pulmonary arterial hypertension (PAH). Little is known on the variations in PA size over time and whether these changes track with disease severity and/or predict long-term survival. METHODS: We included patients with PAH who had at least two computed tomography (CT) scans of the chest done on different visits. Both scans matched the use of i.v. contrast. RESULTS: Pairs of CT scans were compared in 113 PAH patients...
