Uncontrolled hypertension is a significant problem in children with end stage kidney disease. We studied 10 children on chronic hemodialysis who received the endothelin-1 receptor antagonist, bosentan as adjunctive therapy in refractory systemic hypertension. Data were retrospectively analyzed on systolic (SBP) and diastolic blood pressure (DBP), antihypertensive medications and hospitalization...

INTRODUCTION Endothelins are involved in tissue inflammation, pain, edema and cell migration. Our genome-wide microarray analysis revealed that endothelin-1 (ET-1) and endothelin-2 (ET-2) showed a marked up-regulation in dorsal root ganglia during the acute phase of arthritis. We therefore examined the effects of endothelin receptor antagonists on the development of arthritis and inflammatory p...

The aims of this study were to investigate the role of endothelin-1 in FK506-induced hypertension and vascular dysfunction of rats treated with the drug for 8 (short-term) or 30 (long-term) days and to measure malondialdehyde levels in the kidneys. Kidney and mesentery of rats were perfused. In the short-term treated groups, there was no significant change in systolic blood pressure. The respon...

Methods The BENEFiT (Bosentan Effects in iNopErable Forms of chronIc Thromboembolic pulmonary hypertension) study was a double-blind, randomized, placebo-controlled study in CTEPH including patients with either inoperable CTEPH or persistent/recurrent pulmonary hypertension after PEA ( 6 months after PEA). Independent coprimary end points were change in PVR as a percentage of baseline and chang...

A 47 year old woman had had severe idiopathic pulmonary arterial hypertension since 1988. The patient declined treatment with prostanoids or lung transplantation. Her clinical course was extraordinarily stable with merely acenocoumarol and metolazone. In June 2002 right heart catheterisation was performed (mean pulmonary arterial pressure 68 mm Hg, cardiac index 2.0 l/min/m, mixed venous oxygen...

BACKGROUND Patients with Down's syndrome and shunt lesions are at high risk of developing pulmonary arterial hypertension (PAH) earlier than patients without Down's syndrome. However, data on the efficacy of PAH-specific therapy in patients with Down's syndrome are limited. The aim of this retrospective analysis was to determine the long-term efficacy of the dual endothelin receptor antagonist,...

The objective of this study was to investigate the effect a nonselective endothelin-1 (ET-1) receptor antagonist (bosentan) had on the acute myocardial remodeling process including left ventricular (LV) mast cells and matrix metalloproteinase (MMP) activity secondary to volume overload. Additionally, we investigated the overall functional outcome of preventative endothelin receptor antagonism d...

This paper presents the case of a young girl with idiopathic pulmonary hypertension, who developed signs of severe heart failure within a short period of time. Pharmacotherapy with sildenafil and bosentan (among other drugs) was ineffective. Heart catheterization revealed suprasystemic pressure in the pulmonary artery. At the age of 7.5 years, the patient underwent a surgical Potts shunt (namel...

Acute kidney injury (AKI), formly known as acute renal failure (ARF), is an abrupt and reversible decrease in function indicated by the glomerular filtration rate (GFR). Diclofenac-induced AKI due to toxic effect of it on glomeruli, resulting lesions.
 Furthermore, diclofenac causes autolysis, which increase intracellular osmolarity that leads proximal tubular dilatations. Lipoic acid (LA)...
