This study aims to review pediatric pulmonary hypertension (PH) by comparing the guidelines of the European Society of Cardiology (ESC)/European Respiratory Society (ERS), the American Heart Association (AHA)/American Thoracic Society (ATS), and the European Pediatric Pulmonary Vascular Disease Network (EPPVDN). All three sets of guidelines define PH as having a mean pulmonary artery pressure of ≥25 mmHg and accept the validity of the World Health Organization (WHO) classification system. Every child with a high index of suspicion for PH should undergo an initial work-up of chest X-rays, electrocardiography, and echocardiography...

Renal hypoxia is thought to be an important pathophysiological factor in the progression of chronic kidney disease (CKD) and the associated hypertension. In a previous study among CKD patients, supplementation with 100% oxygen reduced sympathetic nerve activity (SNA) and lowered blood pressure (BP). We aimed to assess the underlying haemodynamic modulation and hypothesized a decreased systemic vascular resistance (SVR). To that end, 19 CKD patients were studied during 15-min intervals of increasing partial oxygen pressure (ppO2) from room air (0...

RATIONALE: Page kidney is an uncommon condition that hypertension occurs secondary to microvascular ischemia and alternation of small-vessel hemodynamics due to external compression of renal parenchyma and activation of the renin-angiotensin-aldosterone system. There are no specific guidelines for the management of Page kidney in the literatures. PATIENT CONCERNS: A 17-year-old teenager who had Fontan procedure for tricuspid and pulmonary atresia in early childhood suffered from sudden onset of severe left flank pain during cardiac catheterization procedure...

OBJECTIVES: The CD40L/CD40 pathway is involved in the pathophysiology of atherothrombotic disease, and elevated levels of soluble CD40L (sCD40L) were reported in SLE patients. However, the clinical implication of sCD40L in SLE remains elusive. METHODS: We measured levels of plasma sCD40L in 241 SLE patients and 37 healthy controls and investigated its association with clinical manifestation and laboratory parameters. RESULTS: Levels of plasma sCD40L in SLE patients were significantly elevated compared with healthy controls (p=0...

Background: The fundoscopic examination of hypertensive patients, which is an established hypertension-related target organ damage (TOD), tends to be underutilized in clinical practice. We sought to investigate the relationship between retinal alterations and left atrium (LA) volumes by means of real-time, three-dimensional echocardiography (RT3DE), which is the most pivotal predictor of diastolic dysfunction. Methods: Our population consisted of 88 consecutive essential hypertensive patients (age 59...

Early vascular aging is a process associated with gradual alterations in the vessels, regarding to their structure and function, taking a more rapid course than normal biological aging in the arteries. In the presence of cardiovascular disease, these age-associated alterations are accelerated, contributing for the appearance or the progression of cardiovascular disease, such as high blood pressure, dyslipidemia, smoking and diabetes. Endothelin-1 (ET-1) is the most abundant and important endothelin produced by vascular cells...

Systemic sclerosis, also called scleroderma, is an immune-mediated rheumatic disease that is characterised by fibrosis of the skin and internal organs and vasculopathy. Although systemic sclerosis is uncommon, it has a high morbidity and mortality. Improved understanding of systemic sclerosis has allowed better management of the disease, including improved classification and more systematic assessment and follow-up. Additionally, treatments for specific complications have emerged and a growing evidence base supports the use of immune suppression for the treatment of skin and lung fibrosis...

Daily intake of low-dose aspirin after 12weeks of gestation is currently recommended as a preventative intervention in pregnancies in high risk of developing preeclampsia. This recommendation is based on epidemiological evidence, whereas experimental studies investigating the exact mechanisms of aspirin action during pregnancy are lacking. We previously showed that treating pregnant rats with a synthetic mimetic of unmethylated CpG DNA (bacterial DNA) caused preeclampsia-like characteristics such as maternal hypertension and increased cyclooxygenase (COX) expression and activity...

Pioneering work demonstrated that an unstable substance isolated from rabbit and pig aortas could relax arterial smooth muscle and inhibit platelet aggregation. Since then, prostacyclin (prostaglandin I2, PGI2) and its analogs have raised much pharmacological interest. In this review we detail how the PGI2 signaling pathway is much more complex than was initially anticipated, involving peroxisome proliferator-activated receptors (PPARs), prostaglandin transporters (PGTs), and PGI2-thromboxane A2 (TXA2) receptor (IP TP) heterodimerization...

BACKGROUND: Pulmonary hypertension (PH) is a life-threatening condition that may affect outcomes in patients with systemic lupus erythematosus (SLE). The role of antiphospholipid antibodies (aPL) on the risk of PH is controversial. Therefore our objective was to estimate the risk of PH (WHO groups 1-5) including associated pulmonary arterial hypertension (APAH, WHO group 1 only) related to aPL in patients with SLE. METHODS: Systematic review and meta-analysis were performed: MEDLINE, EMBASE, Cochrane Library, congress abstracts, and reference lists of eligible studies were searched through 2015...

Dysfunction of the NO/sGC/cGMP signaling pathway has been implicated in the pathogenesis of pulmonary hypertension (PH). Therefore, agents stimulating cGMP synthesis via sGC are important therapeutic options for treatment of PH patients. An unwanted effect of this novel class of drugs is their systemic hypotensive effect. We tested the hypothesis that aerosolized intra-tracheal delivery of the sGC stimulator BAY41-8543 could diminish its systemic vasodilating effect.Pharmacodynamics and -kinetics of BAY41-8543 after single intra-tracheal delivery was tested in healthy rats...

Apelin is the endogenous peptide APJ receptor, while APJ is a member of the G protein-coupled receptors family. Recent evidence strongly suggests that Apelin/APJ system influences apoptosis in various diseases through different signal pathways. In this review, we discuss the possible mechanisms by which the Apelin/APJ system inhibits apoptosis, including the phosphatidylinositol-3-kinase (PI3K)/Akt, ERK1/2, caspase signaling, and autophagy pathway. We also summarize the role of Apelin/APJ system in apoptosis in myocardial ischemia-reperfusion (I/R) injury, pulmonary artery hypertension, retinal neovascular disease, acute renal injury, skeletal homeostasis, and gastrointestinal diseases...

Renal sympathetic hyperactivity is critically involved in hypertension pathophysiology; renal denervation (RDN) presents a novel strategy for treatment of resistant hypertension cases. This study assessed effects of two RDN systems to detect acute intravascular, vascular and peri-vascular changes in the renal artery, and renal nerve alterations, in the sheep. The procedures using a single-point or multi-point ablation catheters, Symplicity Flex(TM), Medtronic versus EnligHTN(TM), St. Jude Medical were compared; the intact contralateral kidneys served as controls...

OBJECTIVES: Renal sympathetic denervation has been studied as a potential therapeutic option for patients with therapy-resistant hypertension; however, a significant proportion of patients do not show a significant reduction in blood pressure and are classified as non-responders. The objective of the present study was to assess whether a redo renal denervation procedure increases response rates. METHODS: We present a case series of three consecutive renal denervation non-responders treated with the multi-electrode radiofrequency St...
