Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

Extraction of erythrocyte membrane proteins by sulfhydryl inhibitors. (1/73)

Human red cell membrane proteins were extracted by incubation of the ghost with hypotonic phosphate buffer (pH 7.4), N-ethylmaleimide and p-hydroxy-mercuribenzoate. In paroxysmal nocturnal hemoglobinuria (PNH), hereditary spherocytosis (HS) and hereditary elliptocytosis, the amount of proteins extracted by these procedures was significantly less than the amount extractable from the ghost of normal and aplastic anemia red cells. Polypeptide patterns of red cell membranes in these hematological disorders were essentially similar to those of normal ghosts. Analysis of the supernatant by SDS polyacrylamide gel electrophoresis revealed that this reduction was mainly due to the reduced amount of peripheral proteins extracted. The extraction of peripheral proteins by sulfhydryl reagents was accompanied by shape changes resulting in the formation of membrane vesicles, suggesting an important role of peripheral proteins in the maintenance of ghost shape. It is also suggested that qualitative abnormalities of peripheral proteins such as altered reactivity to sulfhydryl reagents and/or strong binding to the membrane are present in PNH, HS and hereditary elliptocytosis red cells.  (+info)

Acute onset hemoglobinemia and/or hemoglobinuria and sequelae following Rh(o)(D) immune globulin intravenous administration in immune thrombocytopenic purpura patients. (2/73)

Rh(o)(D) immune globulin intravenous (anti-D IGIV) was licensed by the United States Food and Drug Administration (FDA) in March 1995 to treat patients with immune thrombocytopenic purpura (ITP). Anti-D IGIV induces extravascular hemolysis, an expected adverse reaction that is consistent with the presumed mechanism of action. Between licensure and April 1999, the FDA received 15 reports of hemoglobinemia and/or hemoglobinuria following anti-D IGIV administration that met the case definition for this review. The mechanism responsible for hemoglobinemia and/or hemoglobinuria is unexplained. Review of these reports was prompted by the seriousness and the unexpectedness of treatment-associated sequelae experienced by 11 patients. Of these patients, 7 developed sufficient onset or exacerbation of anemia that orders were written for packed red blood cell transfusions, although only 6 patients were transfused. Eight patients experienced the onset or exacerbation of renal insufficiency, and 2 patients underwent dialysis. One patient died due to complications of exacerbated anemia. Six patients experienced 2 to 3 sequelae. Absent validated incidence data, a 1.5% estimated incidence rate from published clinical trial data and a 0.1% estimated reporting rate from FDA and drug utilization data were calculated for reported cases of hemoglobinemia and/or hemoglobinuria. This review presents the first case series of anti-D-IGIV-associated hemoglobinemia and/or hemoglobinuria and provides pretreatment and posttreatment clinical and laboratory findings of the case series patients. The primary purpose of this review is to increase awareness of this potentially serious occurrence among physicians and health care professionals who manage ITP patients treated with anti-D IGIV, thereby enabling prompt recognition and treatment of sequelae.

A model for the sickle hemoglobin fiber using both mutation sites. (3/73)

The standard molecular model of the fiber of the sickle hemoglobin (HbS: beta6 Glu-->Val) has been revised to allow both beta6 mutation sites to participate in intermolecular contacts, rather than only one beta6 site as previously thought, for four molecules per 14-molecule fiber cross section. This structure accurately predicts the copolymerization of hybridized mixtures of HbS with HbA or HbC (beta6 Glu-->Lys), which could not be reconciled with prior models in which only half the beta6 sites were required for assembly. This model suggests new contacts within the fiber and raises the question of whether these cross-linked double strands could possess added stability important in such processes as nucleation.  (+info)

Haemolysis complicating viral hepatitis in patients with glucose-6-phosphate dehydrogenase deficiency. (4/73)

Out of 20 patients with viral hepatitis whose glucose-6-phosphate dehydrogenase (G-6-PD) levels were normal, 14 had clinical evidence of a mild to moderate degree of haemolysis but in all the patients studied the half life of chromium-51-labelled red cells was shortened. Out of 18 viral hepatitis patients deficient in G-6-PD 17 had clinical evidence of haemolysis, and in eight this was more severe than in the group with normal G-6-PD values. Massive intravascular haemolysis occurred in four, three of whom died. The massive haemolysis was attributed to the presence of additional drug-induced oxidative stress to the G-6-PD-deficient red cells.  (+info)

Immune system dysfunction and autoimmune disease in mice lacking Emk (Par-1) protein kinase. (5/73)

Emk is a serine/threonine protein kinase implicated in regulating polarity, cell cycle progression, and microtubule dynamics. To delineate the role of Emk in development and adult tissues, mice lacking Emk were generated by targeted gene disruption. Emk(-/-) mice displayed growth retardation and immune cell dysfunction. Although B- and T-cell development were normal, CD4(+)T cells lacking Emk exhibited a marked upregulation of the memory marker CD44/pgp-1 and produced more gamma interferon and interleukin-4 on stimulation through the T-cell receptor in vitro. In addition, B-cell responses to T-cell-dependent and -independent antigen challenge were altered in vivo. As Emk(-/-) animals aged, they developed splenomegaly, lymphadenopathy, membranoproliferative glomerulonephritis, and lymphocytic infiltrates in the lungs, parotid glands and kidneys. Taken together, these results demonstrate that the Emk protein kinase is essential for maintaining immune system homeostasis and that loss of Emk may contribute to autoimmune disease in mammals.  (+info)

Targeted deletion of the CD59 gene causes spontaneous intravascular hemolysis and hemoglobinuria. (6/73)

The glycolipid-anchored glycoprotein CD59 inhibits assembly of the lytic membrane attack complex of complement by incorporation into the forming complex. Absence of CD59 and other glycolipid-anchored molecules on circulating cells in the human hemolytic disorder paroxysmal nocturnal hemoglobinuria is associated with intravascular hemolysis and thrombosis. To examine the role of CD59 in protecting host tissues in health and disease, CD59-deficient (CD59(-/-)) mice were produced by gene targeting in embryonic stem cells. Absence of CD59 was confirmed by staining cells and tissues with specific antibody. Despite the complete absence of CD59, mice were healthy and fertile. Erythrocytes in vitro displayed increased susceptibility to complement and were positive in an acidified serum lysis test. Despite this, CD59(-/-) mice were not anemic but had elevated reticulocyte counts, indicating accelerated erythrocyte turnover. Fresh plasma and urine from CD59(-/-) mice contained increased amounts of hemoglobin when compared with littermate controls, providing further evidence for spontaneous intravascular hemolysis. Intravascular hemolysis was increased following administration of cobra venom factor to trigger complement activation. CD59(-/-) mice will provide a tool for characterizing the importance of CD59 in protection of self tissues from membrane attack complex damage in health and during diseases in which complement is activated.  (+info)

Conservative treatment of hemolytic complication following coil embolization in two adult cases of patent ductus arteriosus. (7/73)

Two adult cases of relatively large patent ductus arteriosus (PDA) were treated by coil embolization, but were complicated by hemolysis that was successfully managed by medical treatment. Case 1 was a 67-year-old woman and Case 2 was a 71-year-old woman with a PDA of minimal diameter of 5.3 mm and 5.5 mm, respectively. The approach was via the pulmonary artery and 2 coils were delivered simultaneously into the ductus, known as the 'kissing coil technique'. Although immediately after the procedure only a small residual shunt was revealed by aortogram, hemolysis occurred for several hours after the procedure in both cases. A hemolytic complication usually needs additional coil embolization or surgical treatment, but in these 2 cases it was successfully treated by haptoglobin infusion to prevent nephropathy and by antiplasmin infusion to promote thrombus formation. Hemolytic complications of coil embolization of PDA can managed by medication when the residual shunt is minimal and the degree of hemolysis is mild.  (+info)

Exertional hemoglobinuria. (8/73)

A 16 years old boy had a typical exertional hemoglobinuria after walking with his new leather shoes on. The attacks of hemoglobinuria were associated with the appearance of an unstable hemoglobin in red cells. A slightly decreased fragility curve by 24 hr incubated red cells, the increase of autohemolysis and the appearance of heat labile hemoglobin were observed after exertion. These findings support that exertional hemoglobinuria may be regarded as a transitory erythropathia.  (+info)

Paroxysmal cold hemoglobinuria is a hemolytic syndrome. Hemolysis most commonly occurs intravascularly, after the antibody has passed through a cell attachment phase in the lower temperatures of the peripheral circulation.. The Donath-Landsteiner cold hemolysin is an unusual IgG antibody with anti-P specificity that was originally noted in cases of congenital or acquired syphilis. The disease it causes is termed paroxysmal cold hemoglobinuria.. The intravascular hemolysis is due to the unusual complement-activating efficiency of this IgG antibody. As its name implies, this antibody is associated with cold hemoglobinuria. This antibody, although uncommon, is most frequently found in children with viral infections. Hemolysis, even though sometimes severe, is usually mild and tends to resolve as the infection clears.. ...
TY - JOUR. T1 - Assessing donor chimerism using flow cytometry in paroxysmal nocturnal haemoglobinuria after stem cell transplantation--a case report.. AU - Raja Sabudin, Raja Zahratul Azma. AU - Hussin, Noor Hamidah. AU - Chooi Fun, Leong. AU - Ainoon, O.. AU - Cheong, S. K.. PY - 2006/12. Y1 - 2006/12. N2 - Paroxysmal nocturnal haemoglobinuria (PNH) is an acquired haemopoietic stem cell disorder arising from somatic mutation of the X-linked PIG-A gene which leads to deficiency of the glycosylphosphatidylinositol (GP1) membrane anchor proteins such as CD 59 (MIRL: membrane inhibitor of reactive lysis) and CD 55 (DAF: decay accelerating factor). Allogeneic peripheral blood stem cell transplant (PBSCT) is a curative mode of treatment in symptomatic PNH patients. Assessment of donor chimerism for PBSCT can be performed by various methods including short tandem repeat loci (STR) and variable number of tandem repeats (VNTR). Flow cytometry, which is much cheaper and faster, also can be used to ...
This volume reviews the fundamental understanding of this potentially life-threatening disease and the advances in treatment that have been achieved with the use of the monoclonal antibody eculizumab. Although the PIGA gene has been known for many years, the mechanism of clonal dominance in paroxysmal nocturnal hemoglobinuria is still largely unknown. This book, Paroxysmal Nocturnal Hemoglobinuria, discusses the direction of continuing research in this area, as well as the potential for the development of management guidelines. It serves as a valuable source of information for both basic scientists and physicians, especially immunologists targeting GPI-anchored proteins and complements, and hematologists specializing in bone marrow failure. ...
SUMMARY In contrast to all other intrinsic abnormalities of the erythrocyte, paroxysmal nocturnal hemoglobinuria (PNH) is an acquired, not an inherited, disorder. PNH arises as a consequence of somatic mutation, involving one or more hematopoietic stem cells, of PIGA, a gene located on the X chromosome that is required for synthesis of the glycosylphosphatidylinositol (GPI) moiety that anchors some proteins to the cell surface. Consequently, all GPI-anchored proteins (GPI-APs) that are normally expressed are deficient on the mutant hematopoietic stem cells and their progeny. The complement-mediated intravascular hemolytic anemia and the resulting hemoglobinuria that are the clinical hallmarks of PNH are a consequence of deficiency of the GPI-anchored complement regulatory proteins, CD55 and CD59. Although PNH is a neoplastic (clonal) disease, it is not a malignant disease in that there is no exaggerated proliferation of neoplastic cells and replacement of marrow or spread to other tissues, and ...

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare clonal blood disorder that manifests with hemolytic anemia, bone marrow failure, and thrombosis. Many of the clinical manifestations of the disease result from complement-mediated intravascular hemolysis. Allogeneic bone marrow transplantation is the only curative therapy for PNH. Eculizumab, a monoclonal antibody that blocks terminal complement activation, is highly effective in reducing hemolysis, improving quality of life, and reducing the risk for
Intravascular hemolysis in Paroxysmal nocturnal hemoglobinuria (PNH) can effectively be controlled with eculizumab, a humanized monoclonal antibody that binds complement protein C5. We report here a retrospective comparison study between 123 patients treated with eculizumab in the recent period (|2005) and 191 historical controls (from the French registry). Overall survival (OS) at six years was 92% (95%CI, 87 to 98) in the eculizumab cohort versus 80% (95%CI 70 to 91) in historical controls diagnosed after 1985 (HR 0.38 [0.15 to 0.94], p=0.037).

Paroxysmal nocturnal hemoglobinuria (PNH) In this condition, the bone marrow--the soft spongy tissue that act as the blood manufacturing system for the entire body--produces defective red blood cells. The bodys natural defense system then destroys these defective red blood cells in a process is known as hemolysis.
Eculizumab is the current standard of care for the treatment of paroxysmal nocturnal hemoglobinuria (PNH); however, some patients continue to experience ongoing hemolysis and anemia, resulting in red blood cell transfusion dependence, unmet clinical needs, and economic burden. A real-world study presented at the 2020 ASH Annual Meeting observed an economic burden among patients with PNH treated with eculizumab, particularly among those dependent on blood transfusions.. The study included 151 patients aged ≥12 years from the IBM® MarketScan® Research Databases with two or more claims for eculizumab infusion between April 1, 2014, and Sept. 30, 2019. The index date was the first observed claim for eculizumab infusion with three or more months of continuous eligibility prior (baseline period). Patients were then stratified into transfusion-dependent (n=55; 36%; defined as one or more claims for blood transfusion within six months of any eculizumab infusion) and transfusion-free (n=96; 64%) ...

Results At baseline, vWF, sVCAM-1, the EMP count, and F1+2 and D-dimer levels were significantly elevated in the patients, including those with no history of clinical thrombosis. Treatment with eculizumab was associated with significant decreases in plasma markers of coagulation activation (F1+2, p=0.012, and D-dimers, p=0.01), and reactional fibrinolysis (P-AP, p=0.0002). Eculizumab treatment also significantly reduced plasma markers of endothelial cell activation (t-PA, p=0.0005, sVCAM-1, p,0.0001, and vWF, p=0.0047) and total (p=0.0008) and free (p=0.0013) TFPI plasma levels. ...

What: Shares of Alnylam Pharmaceuticals (NASDAQ:ALNY) were trading nearly 10% lower at 10:00 a.m. Monday after the company presented updated clinical data on two of its investigational compounds at the ongoing American Society of Hematology meeting.. So what: On Sunday the company gave an update on its ongoing Phase 1/2 trial of ALN-CC5, a compound being tested as a potential treatment for Paroxysmal Nocturnal Hemoglobinuria, or PNH. The results of the trial showed that ALN-CC5 achieved up to a 99% knockdown of Serum C5 levels and up to a 98% inhibition of Serum Hemolytic activity.. Those results managed to meet the companys goal of an 80% reduction in serum hemolytic activity and Alnylam management team believes that ALN-CC5 showed enough durability to possibly support a monthly, or even quarterly, dose regimen. The company will be transitioning the study to include patients with PNH by the end of this year and it plans on providing updated clinical data from this study by mid-2016.. In a ...

By blocking the complement cascade with eculizumab, clinically evident intravascular hemolysis in PNH is abolished. 8 In this study, we tested for the presence of C3 fragments on the surface of PNH red cells as a possible mechanism for the residual hemolysis occurring in some eculizumab-treated patients. We observed increased levels of C3 fragments on the surface of PNH red cells in many patients who were receiving eculizumab, as also recently reported by Risitano et al.19 The deposition of C3 fragments on PNH red blood cells in this setting could represent the revelation of a pathway of red cell clearance in PNH which is usually obscured by the rapidity of intravascular hemolysis in the absence of eculizumab therapy. Indeed, a small proportion of red cells from a patient with PNH not treated with eculizumab was shown by flow cytometric analysis to have C3 deposition that was undetectable by DAT. This is likely due to the lack of sensitivity of the DAT assay and demonstrates that low levels of ...
Paroxysmal nocturnal haemoglobinuria (PNH) is a clonal haematopoietic stem cell (HSC) disease that presents with haemolytic anaemia, thrombosis and smooth muscle dystonias, as well as bone marrow failure in some cases. PNH is caused by somatic mutations in PIGA (which encodes phosphatidylinositol N-acetylglucosaminyltransferase subunit A) in one or more HSC clones. The gene product of PIGA is required for the biosynthesis of glycosylphosphatidylinositol (GPI) anchors; thus, PIGA mutations lead to a deficiency of GPI-anchored proteins, such as complement decay-accelerating factor (also known as CD55) and CD59 glycoprotein (CD59), which are both complement inhibitors. Clinical manifestations of PNH occur when a HSC clone carrying somatic PIGA mutations acquires a growth advantage and differentiates, generating mature blood cells that are deficient of GPI-anchored proteins. The loss of CD55 and CD59 renders PNH erythrocytes susceptible to intravascular haemolysis, which can lead to thrombosis and to much

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare acquired, life-threatening disease of the blood. The disease is characterized by destruction of red blood cells (hemolytic anemia), blood clots (thrombosis), and impaired bone marrow function (not making enough of the three blood components). PNH affects 1-1.5 persons per million of the population and is primarily a disease of younger adults. The median age of diagnosis is 35-40 years of age, with occasional cases diagnosed in childhood or adolescence. PNH is closely related to aplastic anemia. In fact, up to 30% of newly diagnosed cases of PNH evolve from aplastic anemia. Similarly, the risk of developing PNH after treatment for aplastic anemia with immunosuppressive therapy (anti-thymocyte globulin and cyclosporine) is approximately 20-30%. The median survival after diagnosis is 10 years; however, some patients can survive for decades with only minor symptoms.. PNH occurs when mutations of a gene called PIG-A occur in a bone marrow stem cell. ...
Blood 1998 Dec 1;92(11):4439-45 Abstract quote Hemolytic anemia is a major feature of paroxysmal nocturnal hemoglobinuria (PNH). Intravascular red blood cell (RBC) destruction is caused by increased sensitivity of the abnormal erythrocyte to complement-mediated lysis, due to the GPI absence of a membrane-bound glycosylphosphatidylinositol (GPI)-linked protein, which functions as an inhibitor of reactive lysis (CD59). Both in vivo and in vitro models have suggested the feasibility of cell-to-cell transfer of GPI proteins, and patients with hemolysis could potentially benefit from transfer of CD59 to their deficient erythrocytes. We studied the ability of RBC components prepared from outdated packed RBC collections, as well as high-density lipoprotein (HDL) preparations, rich in CD55 and CD59, to promote protein transfer, as assessed by flow cytometry, immunoblotting, and susceptibility to complement-mediated lysis. By flow cytometry, CD55 and CD59 were present on RBC-derived microvesicles that ...
Paroxysmal nocturnal hemoglobinuria (PNH) is a clonal bone marrow disorder, resulting from an acquired, somatic X-linked mutation of the PIG-A gene in an hematopoietic stem cell. Absence of PIG-A function in a cell prevents synthesis of the glycosylphosphatidylinositol (GPI) moiety, which anchors many different types of proteins to the cell membrane. Intravascular red cell destruction, the hallmark of the disorder, is caused by susceptibility of the abnormal erythrocyte to complement-mediated lysis; this sensitivity is due to lack of CD59, a potent inhibitor of the late components of complement and reactive lysis. In vitro studies from this laboratory have demonstrated transfer of GPI-linked proteins, CD55 and CD59, from normal to deficient cells and transfer is associated with resistance to hemolysis. Patients with PNH frequently require transfusion as their standard care. In addition, patients with all blood groups requiring transfusion will often receive compatible group O blood. Group O ...
The term nocturnal refers to the belief that hemolysis is triggered by acidosis during sleep. However, this observation was later disproved. In individuals with paroxysmal nocturnal hemoglobinuria, hemolysis has been shown to occur throughout the day, but the urine concentrated overnight produces the dramatic change in color.[1] It is most noticeable in the morning, upon passing urine that has accumulated in the bladder during the night.[2] ...
The cause of paroxysmal nocturnal hemoglobinuria is an acquired somatic mutation of the PIG-A-gene in either one or several pluripotent hematopoietic stem cells of the bone marrow [8, 9]. Not all stem cells of the bone marrow are affected, hence a so-called mosaic situation exists. Additional pathophysiological mechanisms may include an autoimmunity-mediated depletion of GPI+-, i.e. healthy stem cells leading to secondary accumulation of GPI-deficient PNH stem cells, and the existence of an intrinsic growth advantage by the GPI deficient stem cells [10]. The predominant consequence of GPI deficiency on peripheral blood cells is the absence of so-called complement-inactivating proteins, especially from the surface of erythrocytes. In this regard, particular mention must be made of CD55, the so-called decay-accelerating factor (DAF) and/or CD59, the membrane inhibitor of reactive lysis (MIRL) [11]. Once complement is activated the red blood cells become vulnerable to terminal ...

Acute Cytomegalovirus (CMV) infection seldom presents with hemolytic anemia in an immunocompetent host. When hemolysis does occur, it is typically immune mediated and extravascular, but can be intravascular with the degree of anemia ranging from mild to severe. We report a case of a healthy 27-year-old woman who presented with jaundice and non-immune mediated intravascular hemolysis as an initial feature of acute CMV infection. Viral etiologies (including CMV) should be considered in the differential diagnosis of patients with Coombs negative intravascular hemolysis.
Intravascular erythrocyte destruction, accompanied by the release of pro-oxidative and pro-inflammatory components hemoglobin and heme, is a common event in the pathogenesis of numerous diseases with heterogeneous etiology and clinical features. A frequent adverse effect related to massive hemolysis is the renal injury and inflammation. Nevertheless, it is still unclear whether heme - a danger-associated molecular pattern and ligand for TLR4 or upstream hemolysis-derived products are responsible for these effects. Well-characterized animal models of hemolysis with kidney impairment are needed to investigate how hemolysis drives kidney injury and to test novel therapeutic strategies. Here we characterized the pathological processes leading to acute kidney injury and inflammation during massive intravascular hemolysis, using a mouse model of phenylhydrazine (PHZ)-triggered erythrocyte destruction. We observed profound changes in mRNA levels for markers of tubular damage (Kim-1, NGAL) and regeneration
Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired hematopoietic stem cell disorder.12 The most common clinical manifestations of PNH include intravascular hemolysis, venous thrombosis, bone marrow failure, and occasional transition to a myelodysplastic syndrome or acute leukemia. The main biochemical feature in PNH is the absence of glycosyl-phosphatidylinositol (GPI)-anchored proteins on the surface of the affected cells, because of incomplete bioassembly of the GPI anchor affixing each protein to the cell surface. The lack of GPI-anchored complement regulatory proteins, including CD55 but especially CD59, results in complement-mediated hemolysis and hemoglobinuria, which is a major clinical manifestation of PNH and an important cause of morbidity and mortality (see Figures 2A and 2B). A humanized monoclonal anti-C5 antibody (eculizumab) that inhibits terminal complement protein activation has recently been approved for PNH in the US and Europe,13-15 suggesting that blocking complement ...
High sensitivity flow cytometry testing for paroxysmal nocturnal hemoglobinuria (PNH) is a test done on patients peripheral blood to screen for the presence or absence of PNH clones and/or to follow PNH clonal populations. The lower limit of detection of a PNH clone for the Spectrum Health laboratory has been validated as 0.01% (1:10,000) for red cells, 0.01% (1:10,000) for granulocytes and 0.1% for monocytes (1:1000).. The results from PNH flow cytometry testing can guide the clinical team in classifying a patients disease appropriately, analyzing the risk of disease progression, and choosing appropriate testing to monitor response to treatment. Therefore, the PNH flow cytometry test result will now include a pathologists interpretation based on the new recommendations given in Updated ICCS/ESCCA Consensus Guidelines for the Clinical Utility of Testing for GPI-Anchor Deficient Clones in Paroxysmal Nocturnal Hemoglobinuria (PNH) and other Bone Marrow Disorders (Accepted article by Dezern and ...

GPI-Anchored Proteins. The majority of eukaryotic cell membrane proteins have hydrophobic amino acids stretches that consists of a transmembrane polypeptide chain, which embeds the proteins into phospholipids double layer of the membrane [18]. GPI anchored proteins are membrane bound proteins. Several proteins are linked to the outer cell membrane leaflet by GPI anchor. This structure involves three key elements: a core containing a phosphatidylinositol (PI) moiety, one glucosamine and three mannose molecules and one ethanolamine phosphate unit [19]. A peptide bond links the C-terminus of the protein polypeptide to the last moiety. The GPI-anchor is created in the endoplasmic reticulum and attached to the polypeptide post-translational by a transaminase enzyme [20-21]. Molecular Genetic Background. Until date, all PNH patients have had genetic mutations in an X-linked gene known as PIG-A [22, 23,9]. The PIG-A gene product is initially required in the assembly of GPI anchors [24]. Consequently, a ...

Background-The cause of inflammatory bowel disease (IBD) is unknown, and it is often difficult to obtain diagnostic histological specimens. In considering the diagnosis of IBD, other causes of enteritis should be excluded. We present a case that illustrates this.. Case report-A 32 year old man presented with a history of intermittent diarrhoea, vomiting, colicky abdominal pain, and weight loss. There was no history of foreign travel or recent contact with gastroenteritis, and he had no family history or past medical history of note. On examination, he was a pale thin man with central abdominal tenderness; other systems were unremarkable. Abnormal blood tests included a raised white cell count 20.4 × 106/l (normal 4-11 × 106), C-reactive protein (CRP) 246 mg/l (normal 1-6 mg/l), and ferritin 310 μg/l (normal 12-1200 μg/l). Stool cultures were negative for pathogenic organisms. Colonoscopy revealed patchy chronic inflammatory infiltration in the lamina propria and enteroscopy showed active ...
tients could have to travel if we create a single Emergency Centre, but some of this comes from a misunderstanding of what the proposed Urgent Care Centres are and what they can do.. These UCCs will be able to treat the majority of conditions our patients presently present at A&E with. Only those who need the most specialised treatment that an Emergency Centre will provide will need to come to the ED.. For those that need that level of specialist care, this single ED would bring together the right people under one roof. There is a whole body of evidence which shows that getting our patients the right treatment by the right people at the right time results in better outcomes for patients and, in the majority of cases, offsets any increase in travel time.. The case for a single Emergency Department serving patients in Shropshire, Telford & Wrekin and mid Wales, forms part of the recommendations in the Strategic Outline Case for the Sustainable Services Programme of The Shrewsbury and Telford ...

Paroxysmal nocturnal hemoblobinuria (PNH) is a rare bone marrow failure disorder that manifests with hemolytic anemia, thrombosis and peripheral blood cytopenias. The absence of two GPI-anchored proteins, CD55 and CD59, leads to uncontrolled complement activation that accounts for hemolysis and other PNH manifestations. GPI anchor protein deficiency is almost always due to somatic mutations in PIGA, a gene involved in the first step of GPI anchor biosynthesis; however, alternative mutations that cause PNH have recently been discovered. In addition, hypomorphic
Introduction Abdominal pain in PNH has never been investigated by in-vivo imaging studies. With MRI, we aimed to assess mesenteric vessels flow and small bowel wall perfusion to investigate the ischemic origin of abdominal pain. Materials and Methods Six PNH patients with (AP) and six without (NOP) abdominal pain underwent MRI. In a blinded fashion, mean flow (MF, quantity of blood moving through a vessel within a second, in mL·s-1) and stroke volume (SV, volume of blood pumped out at each heart contraction, in mL) of Superior Mesenteric Vein (SMV) and Artery (SMA), areas under the curve at 60 (AUC60) and 90 seconds (AUC90) and Ktrans were assessed by two operators. Results Mean total perfusion and flow parameters were lower in AP than in NOP group.
