RATIONALE TAFRO syndrome is a systemic inflammatory disease characterized by a constellation of symptoms: Thrombocytopenia, Anasarca, MyeloFibrosis, Renal dysfunction, and Organomegaly. Progressive renal insufficiency is a predominant symptom; however, the mechanism of acute kidney injury (AKI) remains unclear, probably because severe thrombocytopenia prevents kidney biopsy. We report a rare ca...

BACKGROUND Nephrotic syndrome in children is commonly associated with dyslipidemia, which is considered a risk factor for endothelial dysfunction and atherosclerosis. Recently new markers of endothelial dysfunction, such as asymmetric dimethylarginine (ADMA), have gained importance. Another L-arginine derivative--symmetric dimethylarginine (SDMA)--may reflect the glomerular filtration rate (GFR...

Impaired endothelial barrier function resulting in increased vascular permeability is a characteristic vascular response in preeclampsia, a hypertensive and multiple systemic disorder of human pregnancy. During the last two decades, endothelial function in preeclampsia has been intensively studied and significant progress has been made in understanding the cellular and molecular bases of the al...

Allogeneic stem cell transplantation is commonly used in the treatment of younger patients with severe hematological diseases, and endothelial cells seem to be important for the development of several posttransplant complications. Capillary leak syndrome is a common early posttransplant complication where endothelial cell dysfunction probably contributes to the pathogenesis. In the present stud...

Posterior Reversible Encephalopathy Syndrome (PRES) is an emergency medical condition with varied aetiology, presentation and outcomes reported in literature. It presents clinically as reversible subcortical vasogenic brain oedema caused by endothelial injury resulting from abrupt changes blood pressure or direct effects of cytokines on endothelium damage to barrier excessive exudation parenchy...

The possible role of vascular endothelial cell damage in the loss of intestinal crypt stem cells and the subsequent development of the gastrointestinal (GI) syndrome is addressed. Mice received whole-body epithermal neutron irradiation at a dose rate of 0.57 +/- 0.04 Gy x min(-1). An additional dose was selectively targeted to endothelial cells from the short-ranged (5-9 microm) particles relea...

BACKGROUND The presence of endothelial dysfunction with increased endothelin-1 plasma concentrations in patients with cardiac syndrome X is still under debate. The aim of the present study was to evaluate the presence of endothelial dysfunction in patients with cardiac syndrome X. METHODS AND RESULTS ++Endothelin-1 levels were evaluated with a sensitive radioimmunoassay with previous purifica...

background and objective: vascular endothelial growth factor (vegf) and its receptors (vegf-r1 and r2) are major regulators of angiogenesis. this study was designed to assess serum levels of vegf and vegf-r1 and their prognostic significance in newly diagnosed childhood acute leukemia. materials and methods: for this purpose, vegf and vegf-r1 were determined using enzyme linked immuno-sorbant a...
