Moderate anemia is associated with increased mortality and morbidity, including acute kidney injury (AKI), in surgical patients. A red blood cell (RBC)-specific antibody model was utilized to determine if moderate subacute anemia could result in tissue hypoxia as a potential mechanism of injury. Cardiovascular and hypoxic cellular responses were measured in transgenic mice capable of expressing hypoxia-inducible factor-1α (HIF-1α)-luciferase activity in vivo. Antibody-mediated anemia was associated with mild intravascular hemolysis (6 hours) and splenic RBC sequestration (day 4), resulting in a nadir hemoglobin concentration of 89{plus minus}13 g/L at day 4...

Chronic kidney disease (CKD) occurs in over one-third of patients with sickle cell disease (SCD) and can progress to end-stage renal disease. Unfortunately, current clinical assessments of kidney function are insensitive to early-stage CKD. Previous studies have shown that diffusion magnetic resonance imaging (MRI) can sensitively detect regional renal microstructural changes associated with early-stage CKD. However, previous MRI studies in patients with SCD have been largely limited to the detection of renal iron deposition assessed by T2 * relaxometry...

Objectives: Blood collections from peripheral intravenous catheters offer several benefits to patients, including reduced needle punctures and patient discomfort, but they risk reducing the quality of blood specimens analyzed by the laboratory. In an effort to balance analytical quality of test results with patient-centered care initiatives, a needle-less blood collection device called PIVO™ was evaluated at two institutions. The primary objective of this study was to assess the ability of the PIVO™ device to provide high-quality blood specimens for laboratory testing compared to current blood collection methods...

The eryptotic and hemolytic effects of a phytosterol (PS) mixture (β-sitosterol, campesterol, stigmasterol) and/or β-cryptoxanthin (β-Cx) at physiological serum concentration and their effect against oxidative stress induced by tert-butylhydroperoxide (tBOOH) (75 and 300 µM) were evaluated. β-Cryptoxanthin produced an increase in eryptotic cells, cell volume, hemolysis and glutathione depletion (GSH), without ROS overproduction and intracellular Ca2+ influx. Co-incubation of both bioactive compounds protected against β-Cx-induced eryptosis...

Demand for small diameter vascular grafts is growing. Main limitations of these grafts include induced thrombotic events, lack of in-situ endothelialization, intimal hyperplasia and poor mechanical properties which impair the graft patency rate in long term applications. Most of the used antithrombotic modification methods usually conflict with formation of endothelial cell monolayer on the grafts. Here, we synthesized a novel biodegradable elastic poly (ester ether urethane urea) (PEEUU) using poly (ethylene glycol) (PEG) and poly (diethylene glycol adipate) (PDEGA) as soft segments...

In the present study, two nanoparticles including lactose myristoyl carboxymethyl chitosan (LMCC) and algal polysaccharide myristoyl carboxymethyl chitosan (AMCC), were obtained for hepatic-targeted Adriamycin (ADM) drug delivery systems. ADM was successfully loaded into the LMCC or AMCC nanoparticle by dialysis. The release function and liver targeting of the nanoparticles was explored, and it was revealed that ADM release from the nanoparticles was greatest at acidic pH 5.5. ADM-conjugated nanoparticles were readily taken up by HU7 human hepatocellular carcinoma cells, relative to HT22 mouse hippocampal neuron cells in vitro...

BACKGROUND: Automatic photometric determination of the hemolysis index (HI) on serum and plasma samples is central to detect potential interferences of in vitro hemolysis on laboratory tests. When HI is above an established cut-off for interference, results may suffer from a significant bias and undermine clinical reliability of the test. Despite its undeniable importance for patient safety, the analytical performance of HI estimation is not usually checked in laboratories. Here we evaluated for the first time the random source of measurement uncertainty of HI determination on the two Abbott Architect c16000 platforms in use in our laboratory...

Thrombotic thrombocytopenic purpura is a rare thrombotic disease characterized by episodes of thrombocytopenia and microangiopathic hemolytic anemia due to disseminated microvascular thrombosis. Thrombotic thrombocytopenic purpura was first described in 1924 by Moschowitz as a disease presenting with a pentad of signs and symptoms (anemia, thrombocytopenia, fever, hemiparesis and hematuria). Previous studies have described atypical manifestations of thrombotic thrombocytopenic purpura such as hemolysis, anemia and thrombosis...

INTRODUCTION: Hereditary spherocytosis (HS) is the most common congenital hemolytic anemia, characterized by anemia, jaundice, and splenomegaly. The diagnosis of HS relies on symptoms of hemolysis, a family history of HS, and a positive laboratory test which is usually the osmotic fragility test (OFT). We conducted a study to assess the utility of mean corpuscular hemoglobin concentration (MCHC), mean corpuscular volume (MCV), mean sphered cell volume (MSCV), and mean reticulocyte volume (MRV) in the diagnosis of HS and if these are helpful in distinguishing cases of HS from immune hemolytic anemia...

Vaso-occlusive crisis (VOC) is the most common and debilitating complication of sickle cell disease (SCD); recurrent episodes cause organ damage and contribute to early mortality. Plasma placental growth factor (PlGF) levels are elevated in SCD and can further increase under hypoxic conditions in SCD mice. Treatment with a PlGF-neutralizing antibody (anti-PlGF Ab) in SCD mice reduced levels of monocyte chemoattractant protein-3, eotaxin, macrophage colony-stimulating factor, plasminogen activator inhibitor-1 significantly, and macrophage-derived chemokine and macrophage inflammatory protein-3β moderately; this may contribute to inhibition of leukocyte recruitment, activation, and thrombosis...

Hemolytic factor production by pathogenic Candida species is considered an important attribute in promoting survival within the mammal host through the ability to assimilate iron from the hemoglobin-heme group. Hemolytic capability has been evaluated for Candida species based on hemolysis zones on plate assay, analysis of hemolytic activity in liquid culture medium, and hemolysis from cell-free culture broth. The production of hemolytic factor is variable among Candida species, where C. parapsilosis is the less hemolytic species...

The complement system is essential for host defense, but uncontrolled complement system activation leads to severe, mostly renal pathologies, such as atypical hemolytic uremic syndrome or C3 glomerulopathy. Here, we investigated a novel combinational approach to modulate complement activation by targeting C3 and the terminal pathway simultaneously. The synthetic fusion protein MFHR1 links the regulatory domains of complement factor H (FH) with the C5 convertase/C5b-9 inhibitory fragment of the FH-related protein 1...

Building on the successful military experience, interest has been rekindled in transfusing whole blood (WB) early in the resuscitation of traumatically injured civilians, often before their ABO group is known. WB efficiently provides treatment for shock and coagulopathy, as well as platelet hemostatic function, to patients losing large volumes of blood. Unlike group O uncrossmatched red blood cells (RBCs), group O WB contains a substantial amount of plasma, which is incompatible with the RBCs of all non-group O recipients...

The cause of acute kidney injury during pregnancy and in the postpartum period can be particularly challenging to diagnose, especially when it is necessary to differentiate among preeclampsia; eclampsia; hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome; and thrombotic microangiopathies (TMAs). All these disease entities can present with kidney failure, microangiopathic hemolytic anemia, and thrombocytopenia. We present a teaching case of atypical hemolytic uremic syndrome in the postpartum period in a young woman who was found to have mutations of uncertain clinical significance in the complement cascade, including in C3, CFH, and CFI...
