Obstruction of urine flow at the level of the pelvo-ureteric junction (UPJO) and subsequent development of hydronephrosis is one of the most common congenital renal malformations. UPJO is associated with development of salt-sensitive hypertension, which is set by the obstructed kidney, and with a stimulated renin-angiotensin-aldosterone system (RAAS) in rodent models. This study aimed at investigating the hypothesis that i) in pediatric patients with UPJO the RAAS is activated prior to surgical relief of the obstruction; ii) in rats with UPJO the RAAS activation is reflected by increased abundance of renal aldosterone-stimulated Na+ transporters; and iii) the injured UPJO kidney allows aberrant filtration of plasminogen leading to proteolytic activation of the epithelial sodium channel gamma subunit (γ-ENaC)...

The benefits of inhibiting the renin-angiotensin-aldosterone system (RAAS) are well established for left ventricular dysfunction, but remain unknown for right ventricular (RV) dysfunction. The aim of the current meta-analysis is to investigate the role of RAAS inhibition on RV function in those with or at risk of RV dysfunction. Medline, PubMed, EMBASE and Cochrane Libraries were systematically searched and 12 studies were included for statistical synthesis, comprising 265 RAAS inhibition treatment patients and 265 placebo control patients...

Renin-angiotensin-aldosterone system (RAAS) plays a crucial role in maintaining water and electrolytes homeostasis and its deregulation contributes to the development of arterial hypertension. Since the historical description of the "classical" RAAS, a dramatic increase in our understanding of the molecular mechanisms underlying the development of both essential and secondary hypertension has occurred. Approximatively 25% of the patients affected by arterial hypertension display low renin levels, a definition that is largely arbitrary and depends on the investigated population and the specific characteristics of the assay...

Sodium glucose cotransporter 2 (SGLT2) inhibitors are a relatively new class of anti-hyperglycemic drugs with a distinctive mechanism of action focusing on renal absorption ofglucose. Apart from its anti-hyperglycemic effects, a multitude of research studies on this classhave revealed that these drugs have far more versatile and comprehensive pharmacologicaleffects than previously believed. Approximately 30% of FDA approved drugs are repurposedand used for indications other than those they were initially intended for...

OBJECTIVE: Emerging evidence support a positive, bidirectional and clinical relevant interaction between parathyroid hormone (PTH) and the renin-angiotensin-aldosterone-system (RAAS). A beneficial effect of the widely used RAAS inhibitors might include a PTH lowering effect, as high PTH levels may be harmful to cardiovascular health. We aimed to investigate whether PTH levels are lowered by short-term treatment with an angiotensin 2 receptor blocker (valsartan) independently of co-administration of vitamin D3...

INTRODUCTION: Renal artery aneurysm (RAA) is a rare clinical entity with an estimated prevalence of 0.15% to 0.1%in the general population. The majority of patients present asymptomatically and the diagnosis is made incidentally during a hypertension study test, and more rarely, fortuitously after backache. Indications to treat have been subject of intense debate, nevertheless there seems to be some consensus that RAAs greater than 2 cm in diameter, expanding RAA, with thrombus or in pregnant women should be treated...

BACKGROUND: Qiliqiangxin capsule (QLQX), composed of 11 herbs, is an effective traditional Chinese medicine (TCM) that has been widely used for treatment of chronic heart failure (CHF) in China. In the Chinese pharmacopoeia (Ch.P.) only astragaloside was described as the marker component to control the quality of QLQX, which could not reflect the overall effectiveness. PURPOSE: The aim of this work was to investigate the quality markers (Q-markers) of QLQX based on the association of the pharmacodynamics (PD) of inhibitory effect on activated renin-angiotensin-aldosterone system (RAAS) and the pharmacokinetics (PK) of bioactive compounds according to the Q-marker theory...

Hajdu Cheney syndrome is a rare autosomal dominant skeletal dysplasia, with multi-organ involvement, caused by pathogenic variants in NOTCH2. It is characterized by progressive focal bone destruction, including acro-osteolysis and generalized osteoporosis, craniofacial anomalies, hearing loss, cardiovascular involvement and polycystic kidneys. Distinct radiographic findings, such as a serpentine fibula, may aid in facilitating the diagnosis. Despite several dozens of cases described in the literature, diagnosis often remains elusive, resulting in many cases in a delay in diagnosis reaching adolescence or adulthood...

BACKGROUND: Augmented sympathetic nerve activity (SNA) and renin-angiotensin-aldosterone system (RAAS) activity are involved in the pathogenesis of hypertension (HT) accompanied by chronic kidney disease (CKD). Oxidative stress in the hypothalamus increases SNA in HT. Administration of an angiotensin ΙΙ receptor blocker (olmesartan; OLM) or renal denervation (RDN) exerts an antihypertensive effect in HT with CKD; however, the precise mechanisms of the combination therapy are not fully elucidated...

Fragile X Syndrome (FXS), the most common form of inherited mental retardation, is caused by a trinucleotide repeat expansion (CGG) in the 5'-untranslated region of the Fragile X Mental Retardation 1 (FMR1) gene located at Xq27.3. Patients with fragile X -related mental retardation, carry the full mutation CGG-repeat expansions (>200 CGG repeats), which are generally accompanied by hypermethylation of the promoter region, with the consequent transcriptional silencing of the FMR1 gene and absence of the encoded FMR1 protein (FMRP)...

BACKGROUND: The prevalence of type 2 diabetes mellitus (T2DM) is increasing worldwide. T2DM is associated with serious macro- and microvascular complications. In particular, diabetic kidney disease (DKD), which begins with excessive urinary albumin excretion, has a significant impact on affected individuals and is costly to healthcare services. Inhibition of the renin-angiotensin-aldosterone system (RAAS) with angiotensin converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) significantly reduces albuminuria in diabetes, but this effect is not observed in all those treated...

The present study is the first reported case of a patient undergoing esophagectomy with ectopic aortic arch secondary to a large esophageal cancer, which was pre-operatively misdiagnosed with a right-side aortic arch (RAA). The patient, a 54-year-old male, was first admitted to our hospital for esophagectomy owing to esophageal squamous cancer and had complained of progressive dysphasia for 3 months. Chest computed tomography (CT) revealed a mass in the middle thoracic esophagus. Furthermore, the three-dimensional CT of the thoracic great arteries showed a possible RAA and a curved descending aorta...

Diabetic kidney disease (DKD) is a major factor associated with increased cardiovascular (CV) and all-cause mortality and morbidity in patients with diabetes. Current standard therapy includes intensive management of hyperglycemia and blood pressure control with renin-angiotensin-aldosterone system (RAAS) blockers. Despite the implementation of this strategy, DKD remains the leading cause of end-stage renal disease (ESRD), mainly because of the increasing burden of diabetes mellitus. The aim of this review is to evaluate the available evidence, focusing on the benefit of current treatment in the development and progression of DKD...

Renin-angiotensin-aldosterone system (RAAS) plays important roles in regulating renal hemodynamics and functions, as well as in the pathophysiology of hypertension and renal disease. In the kidney, angiotensin II (Ang II) production is controlled by independent multiple mechanisms. Ang II is compartmentalized in the renal interstitial fluid with much higher concentrations than those existing in the circulation. Inappropriate activation of the intrarenal RAAS is an important contributor to the pathogenesis of hypertension and renal injury...
