Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator.Purpura, Thrombocytopenic: Any form of purpura in which the PLATELET COUNT is decreased. Many forms are thought to be caused by immunological mechanisms.CD4 Lymphocyte Count: The number of CD4-POSITIVE T-LYMPHOCYTES per unit volume of BLOOD. Determination requires the use of a fluorescence-activated flow cytometer.Antigens, Human Platelet: Human alloantigens expressed only on platelets, specifically on platelet membrane glycoproteins. These platelet-specific antigens are immunogenic and can result in pathological reactions to transfusion therapy.Platelet Activation: A series of progressive, overlapping events, triggered by exposure of the PLATELETS to subendothelial tissue. These events include shape change, adhesiveness, aggregation, and release reactions. When carried through to completion, these events lead to the formation of a stable hemostatic plug.Hemostasis: The process which spontaneously arrests the flow of BLOOD from vessels carrying blood under pressure. It is accomplished by contraction of the vessels, adhesion and aggregation of formed blood elements (eg. ERYTHROCYTE AGGREGATION), and the process of BLOOD COAGULATION.Blood Coagulation: The process of the interaction of BLOOD COAGULATION FACTORS that results in an insoluble FIBRIN clot.Thrombosis: Formation and development of a thrombus or blood clot in the blood vessel.Microchemistry: The development and use of techniques and equipment to study or perform chemical reactions, with small quantities of materials, frequently less than a milligram or a milliliter.Blood Platelet Disorders: Disorders caused by abnormalities in platelet count or function.P-Selectin: Cell adhesion molecule and CD antigen that mediates the adhesion of neutrophils and monocytes to activated platelets and endothelial cells.Splenectomy: Surgical procedure involving either partial or entire removal of the spleen.von Willebrand Factor: A high-molecular-weight plasma protein, produced by endothelial cells and megakaryocytes, that is part of the factor VIII/von Willebrand factor complex. The von Willebrand factor has receptors for collagen, platelets, and ristocetin activity as well as the immunologically distinct antigenic determinants. It functions in adhesion of platelets to collagen and hemostatic plug formation. The prolonged bleeding time in VON WILLEBRAND DISEASES is due to the deficiency of this factor.Time Factors: Elements of limited time intervals, contributing to particular results or situations.Rabbits: The species Oryctolagus cuniculus, in the family Leporidae, order LAGOMORPHA. Rabbits are born in burrows, furless, and with eyes and ears closed.

Background: Coated-platelets, a subset of activated platelets observed with dual-agonist stimulation with collagen and thrombin, represent 30% of the platelet population in normal controls. In recently published work, we have shown that elevated coated-platelet levels (,45%) are predictive of stroke in asymptomatic carotid stenosis. We now investigate if platelet count and mean platelet volume (MPV) are related to coated-platelet levels.. Methods: Coated-platelet levels were measured in a cohort of asymptomatic outpatients referred for carotid ultrasound studies. Platelet count and mean platelet volume for ...
Background Platelet transfusions are used in modern clinical practice to prevent and treat bleeding in people who are thrombocytopenic due to bone marrow failure. Although considerable advances have been made in platelet transfusion therapy in the last 40 years, some areas continue to provoke debate, especially concerning the use of prophylactic platelet transfusions for the prevention of thrombocytopenic bleeding. This is an update of a Cochrane review first published in 2004, and previously updated in 2012 that addressed four separate questions: prophylactic versus therapeutic-only platelet transfusion policy; prophylactic platelet transfusion threshold; prophylactic platelet transfusion dose; and platelet transfusions compared to alternative treatments. This review has ...
Differential diagnosis of thrombocytosis is not always obvious. The routine clinical chemistry laboratory classically provides only limited help in distinguishing between reactive thrombocytosis (RT) and autonomous thrombocytosis, where platelet production escapes normal regulatory processes, and which is seen in myeloproliferative diseases (MPD) such as essential thrombocythemia and polycythemia vera. We explored the clinical use of platelet distribution width (PDW) in the differential diagnosis of thrombocytosis. During a 3-month period, 250 patients presenting with a platelet count , 500 x 10(9)/L were studied; 174 were classified as having RT, 42 had a diagnosis of MPD, and 34 patients were excluded because they had a hemopathy different from MPD, and either did or did not present a known etiologic factor for RT. First, we determined that in the RT group the value of PDW ...
BACKGROUND: Eltrombopag is an oral, non-peptide, thrombopoietin-receptor agonist that stimulates thrombopoiesis, leading to increased platelet production. This study assessed the efficacy, safety, and tolerability of once daily eltrombopag 50 mg, and explored the efficacy of a dose increase to 75 mg. METHODS: In this phase III, randomised, double-blind, placebo-controlled study, adults from 63 sites in 23 countries with chronic idiopathic thrombocytopenic purpura (ITP), platelet counts less than 30 000 per muL of blood, and one or more previous ITP treatment received standard care plus once-daily eltrombopag 50 mg (n=76) or placebo (n=38) for up to 6 weeks.

SOUZA, AM et al. Platelet indices in dogs with thrombocytopenia and dogs with normal platelet counts. Arch. med. vet. [online]. 2016, vol.48, n.3, pp.277-281. ISSN 0301-732X. http://dx.doi.org/10.4067/S0301-732X2016000300005.. It is well known that thrombocytopenia is the most commonly acquired haemostatic disorder in dogs and can be potentially life-threatening. With the use of automated analysers, platelet indices such as Mean Platelet Volume (MPV), Platelet Distribution Width (PDW), and Platelet Large Cell Ratio (P-LCR), became routinely available, allowing data comparison and error checks which results in a more effective quality control. The aim of this study was to evaluate the pattern of platelet indices (MPV, PDW and P-LCR) in dogs ...
Platelet membrane glycoprotein Ib (GPIb), a receptor for von Willebrand factor and thrombin, is present on the platelet surface membrane, in intraplatelet stores, and in plasma (as the proteolytic fragment glycocalicin). We examined the hypothesis that after plasmin-mediated cleavage of platelet surface GPIb, platelets can replenish their surface GPIb pool. Incubation of washed platelets with plasmin (1 hour, 22 degrees C) resulted in loss of platelet surface GPIb, but further incubation (3 hours, 37 degrees C) in autologous plasma resulted in restoration of platelet surface GPIb, as determined by ristocetin-induced platelet agglutination and a flow cytometric assay of ...
Material and Methods: A total of 160 cases with cirrhosis due to any cause were included in this study. The study included both male and female subjects and was restricted to age 35-70 years. Exclusion criteria were also applied to this group of patients. All these patients underwent blood test for platelet count and ultrasound abdomen for splenic diameter. For each patient calculation of platelet/splenic ratio was determined with a cut off value of 909 determined. Values greater than this cut off were supposed not to have high risk esophageal varices. Upper gastrointestinal endoscopies were performed on all patients and then on the basis of endoscopy results the patients were divided into two groups, first group in which high risk EVs (grade 2 and grade 3) were present and second group in which they were absent. Subsequently sensitivity, specificity, predictive values and accuracy were ...
In this study, we show that the platelet surface expression of glycoprotein (GP) V is regulated by two independent mechanisms. While confirming that both thrombin and neutrophil elastase proteolyse GPV, we show that neutrophil cathepsin G, thrombin receptor activating peptide (TRAP), and a combination of ADP and epinephrine can each result in a decrease in the platelet surface expression of GPV by a nonproteolytic mechanism: a cytoskeletal-mediated redistribution of platelet surface GPV to the surface-connected canalicular system (SCCS). Four independent lines of evidence documented the nonproteolytic nature of this decrease in the platelet surface expression of GPV. First, flow cytometric studies showed that cathepsin G, TRAP, and ADP/epinephrine decreased the platelet surface expression of GPV without changing the total ...
Abstract:. Aims and Objective: To determine the role of Moringa oleifera on total platelet count alterations (T-PC) in rats treated with cadmium.

While these food groups are essential to help you combat instances of having platelet count low in number, its better to start on a diet with the help of your general practitioner or nutritionist, more importantly if you dont carry any guide with you. This is also important in order to specifically understand - what does a low platelet count mean - in your case and what thrombocytopenia treatment option is the most appropriate. Many people often disregard the occurrence of food allergies when they change their diet. Be careful, especially with regards to doubtful approaches. Food allergies can have severe side effects such as depression, constant fatigue and even cell destruction. In this event, allergic reactions caused by diet changes might actually lead to the destruction of healthy blood cells instead of the purpose of helping with regeneration of the ...

Approach and Results-To model standard antiplatelet therapy, platelets were treated in vitro with aspirin, the P2Y12 receptor blocker prasugrel active metabolite, and aspirin plus prasugrel active metabolite. Different proportions of uninhibited platelets were then introduced. Light transmission aggregometry analysis demonstrated clear positive associations between proportions of drug-free platelets and percentage platelet aggregation in response to a range of platelet agonists. Using differential platelet labeling coupled with advanced flow cytometry and confocal imaging, we found aggregates formed in mixtures of aspirin-inhibited platelets and drug-free platelets were characterized by intermingled ...
An elevated platelet count can be primary or secondary. Primary thrombocytosis is called essential thrombocytosis. It is a form of myeloproliferative disease. However, platelets are also an acute phase reactant. This means that their number increases in states of stress. This is called reactive thrombocytosis. Trauma is definitely stressful. A deep vein thrombosis is also stressful. But was is the expected amount of thrombocytosis in major trauma? Is it 10%? 20%? Is 950,000 highly unlikely? There is no study that examined this specifically, but such high numbers are seen not infrequently.. Thrombosis with thrombocytosis occurs especially with essential thrombocytosis. Most of the thrombotic events are arterial, however venous thrombosis is possible. Thrombosis with reactive thrombocytosis has been described, but it is unlikely, especially with relatively low platelet ...

Mean platelet volume (MPV) is a machine-calculated measurement of the average size of platelets found in blood and is typically included in blood tests as part of the CBC. Since the average platelet size is larger when the body is producing increased numbers of platelets, the MPV test results can be used to make inferences about platelet production in bone marrow or platelet destruction problems. MPV is higher when there is destruction of platelets. This may be seen in inflammatory bowel disease, immune thrombocytopenic purpura (ITP), myeloproliferative diseases and Bernard-Soulier syndrome. It may also be related to pre-eclampsia, and recovery from, transient hypoplasia. Abnormally low MPV values correlate with thrombocytopenia when it is ...

In a prospective trial, the immediate and long-term haematological effects of amrinone were studied in sixteen patients with refractory cardiac failure. The platelet count was significantly and variably reduced in all patients and the reduction was related to log plasma amrinone concentration. Platelet survival was significantly reduced in those cases studied. No evidence of disseminated intravascular coagulation or intravascular platelet deposition was observed and the reduced platelet survival was not considered to be the result of an immunological process. Evidence of a marrow response to the reduced platelet count and survival was seen. Although no haemorrhagic symptoms were observed in the patients, the haematological side-effects were considered to be of such severity ...

Megakaryocytes generate platelets by remodeling their cytoplasm into long proplatelet extensions, which serve as assembly lines for platelet production. Although the mechanics of proplatelet elongation have been studied, the terminal steps of proplatelet maturation and platelet release remain poorly understood. To elucidate this process, released proplatelets were isolated, and their conversion into individual platelets was assessed. This enabled us to (a) define and quantify the different stages in platelet maturation, (b) identify a new intermediate stage in platelet production, the preplatelet, (c) delineate the cytoskeletal mechanics ...
Platelet Count-A platelet count is a type of lab test that measures the number of platelets in your blood. Know normal range, causes of high and low count
Introduction: S100A1 is a member of the S100 family of calcium-binding proteins. S100A1 controls Ca2+ dynamics in cardiomyocytes and plays an important role in heart failure. S100A1 is also strongly expressed in mouse platelets, but its role in platelet biology has not been investigated.. Goal: To determine the role of S100A1 in platelet activation and thrombosis.. Methods and Results: Platelet activation in response to threshold levels of convulxin, a specific agonist for the collagen receptor GPVI, showed significantly increased activation of αIIbβ3 integrin and α-granule release in S100A1-deficient (SKO) platelets compared with wild-type (WT) platelets. Consistently, SKO platelets also showed a more robust aggregation response to convulxin and collagen. In contrast, SKO ...
Platelets are cell fragments which are mainly an essential component when it comes to blood clotting and coagulation. The platelets along with the red blood cells and white blood cells, function together for the regulation and normal functioning of blood in our body. The blood cells have each of their own different life span as well as different functions. Among these three, the platelets are the smallest but one of the most important factors in blood clotting. If the platelets dont get regulated properly, such as when they dont get renewed at normal intervals, then the blood dysfunction or disorder might occur.. The general lifespan of a platelet is about 10 days. The normal platelet ...
Thrombocytopenia is one of many blood disorders where there is a low count of the platelet.

The term idiopathic thrombocytopenic purpura (ITP) describes an autoimmune disorder. Learn more about Idiopathic Thrombocytopenic Purpura (ITP)
The exact cause of the condition is not known. But it is believed that an autoimmune response causes idiopathic thrombocytopenic purpura (ITP).
Oxidized LDL and platelets play a central role in the pathogenesis of atherosclerosis and ischemic cardiovascular diseases. Lysophosphatidic acid (LPA) is a thrombogenic substance that accumulates in mildly-oxidized LDL and in human atherosclerotic lesions, and is responsible for the initial platelet activation, shape change, induced by mildly-oxidized LDL and extracts of lipid-rich atherosclerotic plaques (Siess et al., 1999 Proc Natl Acad Sci USA 1999). LPA directly induced platelet shape change in blood and platelet-rich plasma (PRP) obtained from all blood donors. Albumin was one of the main inhibiting factors of platelet shape change in plasma. Interestingly LPA, at concentrations slightly above plasma levels, induced platelet shape change and aggregation in ...
Initially, immune (idiopathic) thrombocytopenic purpura (ITP) was considered to be a disease of increased platelet destruction. Consequently, treatments for ITP patients were focused on reducing the destruction of platelets. However, recent research on the pathogenesis of ITP points to a role of suboptimal platelet production, and this has led to the development of new treatment options which increase platelet production such as the novel thrombopoiesis-stimulating agent, romiplostim. In two, multicentre, randomized, placebo-controlled, double-blinded, phase III trials, romiplostim was able to increase and sustain platelet counts in both splenectomized and non-splenectomized patients. Eighty-three per cent (69/83) of the romiplostim-treated patients achieved an overall ...

If the bruising and bleeding you are experiencing is determined to be a consequence of a low platelet count, your doctor may prescribe a blood cell growth factor. Blood cell growth factors are substances produced by your body to stimulate the bone marrow to produce more platelets. If you have a severely low platelet count, you may require treatment with platelet transfusions and occasionally, admission to the hospital until the platelets return to sufficient levels in the blood to prevent bleeding.. Oprelvekin (Neumega®): The blood cell growth factor approved by the Food and Drug Administration for the prevention of a low platelet count is ...

Reuters) - Scientists have for the first time created blood platelet cells by reprogramming stem cells derived from adult cells, offering the potential for a renewable supply of the fragile blood component.. Researchers at the Center for iPS Cell Research and Application at Kyoto University in Japan presented data here at a meeting of the American Society of Hematology showing they were able to create the cells in the laboratory and confirm they had the same life span as normal human platelets when infused in mice.. "The next step will be to conduct a trial to determine whether our platelets can function in the human body and potentially provide a stable supply of platelets at a predefined quality and quantity that can then be used for transfusion therapy," D. Koji Eto, professor at the Kyoto center and senior author of the study, said in a ...
Idiopatic thrombocytopenic purpura (ITP), a disorder characterized by autoantibody-mediated platelet destruction, may be primary or secondary to various illnesses including lymphoproliferative, autoimmune, or infectious diseases. There are increasing data on the association between Helicobacter pylori infection and idiopathic thrombocytopenic purpura and the significant increase in platelet count after bacterial eradication. The aim of this review is to consider the studies so far published on Helicobacter pylori infection and idiopathic thrombocytopenic purpura in order to evaluate a possible pathogenic correlation between these two conditions. A review of the literature data show that Helicobacter pylori eradication in patients with idiopathic thrombocytopenic purpura is effective in increasing platelet count in approximately half of the ...
inbook{d2d8fceb-9b60-4916-ad95-3b1f6f9113f7, abstract = {,p,Many pathogenic bacteria have been reported to interact with human platelets to mediate platelet activation and aggregation. The importance of these interactions to the immune response or pathogenesis of bacterial infection has not been clarified. It may therefore be valuable to assess platelet responses mediated by diverse strains of bacteria. Here, I describe a method to study platelet integrin activation and granule release using flow cytometry, and a complementary method to study platelet aggregation using a dedicated platelet aggregometer. The combination of these methods represents a rapid and cost-effective strategy to provide mechanistic insight on the type of platelet response mediated by the ...
Pivotal Phase 3 Romiplostim Study in Splenectomized Patients Meets Primary Endpoints Data Show Romiplostim Increased and Sustained Platelet Counts in Splenectomized Adult Patients with Immune Thrombocytopenic Purpura ATLANTA--(BUSINESS WIRE)--Dec. 8, 2007--Amgen Inc.

Adult ITP is a serious chronic autoimmune disorder characterized by low platelet counts in the blood, a condition known as ...
Idiopathic Thrombocytopenic Purpura: Thrombocytopenia occurring in the absence of toxic exposure or a disease associated with decreased platelets. It is mediated by immune mechanisms, in most cases IMMUNOGLOBULIN G autoantibodies which attach to platelets and subsequently undergo destruction by macrophages. The disease is seen in acute (affecting children) and chronic (adult) forms.

We deserve no credit for the muddied waters of heparin-induced thrombocytopenia terminology. The concept of early, mild, nonimmune, clinically inconsequential heparin-induced thrombocytopenia was advanced years ago as heparin-induced thrombocytopenia type 1 (1). In fact, low platelet counts in some hospitalized patients may often be unrelated to heparin and may be due instead to infection, surgery, other drugs, and stresses. The recommendation to designate this as heparin-associated thrombocytopenia to distinguish it from serious heparin-induced thrombocytopenia (2) has not gained wide favor. Furthermore, separating heparin-induced thrombocytopenia from heparin-induced thrombocytopenia with thrombosis syndrome is artificial and misleading, since isolated heparin-induced ...
Dear Sir:. When platelets are activated, they increase in size and change from a quiescent disc to a swollen sphere. Large platelets are more reactive and likely aggregate more than small ones [1]. Mean platelet volume (MPV), an indicator of platelet size and activation, has been shown to predict ischemic stroke, myocardial infarction, and overall vascular mortality [2,3]. The IMProved Reduction of Outcomes: Vytorin Efficacy International Trial (IMPROVEIT) study showed that ezetimibe added to statin therapy further decreases low density lipoprotein cholesterol (LDL-C) levels and prevented acute coronary syndromes [4]. In this study, we investigated the lowering effect of LDL-C and MPV changes in patients who are on statin-ezetimibe combination therapy and those who receive statin monotherapy.. Patients with acute ischemic cerebral infarctions (n=120) were divided into those ...

When a well child comes to accident and emergency (A&E) with a history of sudden onset bruising, purpura and petechiae, and is found to have an isolated severe thrombocytopenia (TP), the diagnosis is usually obvious: acute immune thrombocytopenic purpura (ITP). But, could something more sinister be going on? Is ITP the correct diagnosis?. This article outlines the features that should make a clinician suspect there may be an alternative diagnosis. Aware of the possible differential diagnoses, the clinician can appropriately investigate and manage the child with ITP, and know when to refer to a paediatric haematologist for specialist help ...
Treatment of thrombocytopenia varies according to the cause. If thrombocytopenia is drug-induced, then removal of the offending agents should correct the condition.. Corticosteroids may be used to increase platelet production. Lithium carbonate or folate may also be used to stimulate the bone marrow production of platelets. Platelet transfusions may be used to stop episodic abnormal bleeding caused by a low platelet count. However, if platelet destruction results from an immune disorder, platelet infusions may have only a minimal effect and may be reserved for life-threatening bleeding.. Splenectomy may be necessary to correct thrombocytopenia caused by platelet destruction. A splenectomy should significantly reduce ...

Thrombocytopenia, encountered frequently among patients with HCV-related chronic hepatitis and cirrhosis, is usually aggravated during IFN-based antiviral therapy. In several large-scale clinical trials, the incidence of severe on-treatment thrombocytopenia was 3-5% among all patients with chronic hepatitis C [2-4]. In the current study, severe thrombocytopenia occurred more frequently (12.8%) in patients with baseline thrombocytopenia. Roomer et al. (2010) documented that patients with baseline thrombocytopenia were vulnerable to severe thrombocytopenia [5]. This group also found that severe thrombocytopenia was significantly associated with bleeding events. In the present study, severe thrombocytopenia did occur in some patients during antiviral therapy, but it was not followed by mortality or major morbidity. Instead, severe thrombocytopenia was associated with higher rates of premature discontinuation of therapy.. Thrombocytopenia is one of the extrahepatic ...

Thrombocytopenic purpura are purpura associated with a reduction in circulating blood platelets which can result from a variety of causes, such as kaposi sarcoma. By tradition, the term idiopathic thrombocytopenic purpura is used when the cause is idiopathic. However, most cases are now considered to be immune-mediated. Another form is thrombotic thrombocytopenic purpura. Diagnosis is done by the help of symptoms and only blood count abnormality is thrombocytopenia.

SUMMARY The numbers of platelet transfusions administered in the United States increased dramatically during the 1980s, and has continued to grow as increasingly aggressive medical and surgical treatments have been developed and become more widely available. In particular, the growth of more intensive treatments for hematologic and other malignancies has spurred demands for platelet transfusion support and put pressure on platelet inventories nationwide.. The response to a platelet transfusion is affected by platelet recovery and platelet survival and includes the random loss of platelets in maintaining endothelial integrity. In a normal individual, weighing 70 kg, approximately 4.8 × 1010 platelets per day will be consumed maintaining the ...

Abstract: We performed a prospective pilot study on 12 patients to evaluate the efficacy of the anti-CD20 monoclonal antibody rituximab in relapsed idiopathic thrombocytopenic purpura (ITP). Inclusion criteria were relapse of ITP with a thrombocyte count ,20 000 µL−1 and unsuccessful corticosteroid treatment. Eleven patients had a previous splenectomy, five patients had unsuccessful cytotoxic treatment, and six patients were refractory to intravenous immunoglobulins before rituximab therapy. Response criteria were as follows. Complete remission (CR): normalization of thrombocyte count for at least 30 d. Partial remission (PR): an increase of thrombocytes to above 30 000 µL−1 for at least 30 d. Minor response (MR): any increase above 30 000 µL−1 for less than 30 d but more than 10 d. No response (NR): failure to achieve any of the above responses. Treatment plan: We administered 375 mg m−2 of rituximab once weekly on up to four consecutive ...
BACKGROUND: Acute idiopathic thrombocytopenic purpura(ITP) is one of the common hematologic disorders in children. Bone marrow aspiration(BMA) is often performed in children with acute ITP to rule out leukemia, aplastic anemia or other hematologic diseases. However, whether BMA is needed in children with typical clinical and hematological features of acute ITP have been questioned. This study was performed to examine the proper indication of BMA in acute childhood ITP. MATERIALS AND METHODS: The medical records and BMA reports of children with the provisional diagnosis of acute ITP were reviewed from January 1984 to December 2000. Patients were divided into two groups, one with typical and another with atypical clinical and hematological features of acute ITP. Typical acute ITP group was characterized by the history of previous viral infection, well being appearance, no hepatosplenomegaly, no lymphadenopathy, normal Hb, WBC, neutrophil count and peripheral ...

Since 1931, sporadic reports have appeared noting an apparent association between hyperthyroidism and idiopathic thrombocytopenic purpura (ITP) (1-4). During a recent survey of our patients with ITP (5), we were impressed with what seemed to be an increased prevalence of hyperthyroidism in this group. This observation prompted us to study patients with ITP who were clinically euthyroid to determine if latent Graves disease existed in this population.. The data reported here indicate that there is indeed an increased prevalence of hyperthyroidism and of latent Graves disease in patients with ITP. They suggested that these two diseases may share a similar ...

On November 20, 2008, the U. S. Food and Drug Administration (FDA) approved eltrombopag tablets (Promacta ®, GlaxoSmithKline Inc.) for the treatment of thrombocytopenia in patients with chronic immune (idiopathic) thrombocytopenic purpura (ITP) who have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy.. Eltrombopag is an orally-administered thrombopoietin receptor agonist that stimulates bone marrow megakaryocytes to produce platelets. Data supporting this indication were derived from a controlled clinical study of patients treated over a six week period, and a single-arm extension study treating patients for multiple months.. Further studies for long-term efficacy and safety have since been performed. In September 2010, NICE (The National Institute for Health and Clinical Excellence, the drug efficacy and certifying agency for England and Wales) decided to "not recommend" the drug for the above indications, citing high costs as the primary ...

Today we will be discussing fetal and neonatal alloimmune thrombocytopenia, also referred to as NAIT, which affects about 1 in 1,000 births. NAIT is caused by maternal alloantibodies to specific platelet antigens, usually human platelet antigen 1a also referred to as HPA-1a. These antigens may be inherited from the father but are absent in the mother. Only 2% of women are HPA-1a negative and at risk to produce these alloantibodies which can lead to fetal thrombocytopenia.. Dr. Bussel, who wrote an Editorial on the subject, discusses the morbidity and mortality associated with NAIT.. "If the platelets are low enough, there is a serious risk of bleeding. When the fetal platelet get low enough, then the fetus may bleed in the brain and most of the bleeding in the brain that happens in fetuses and neonates affected by NAIT, occurs in utero, not after birth.". Currently, there ...
BACKGROUND: Thrombocytopenia occurs early during malarial infection, but its underlying mechanism is unclear. Secretion of von Willebrand factor (vWF) occurs on endothelial cell activation, and it plays an important role in platelet agglutination. METHODS: In 14 healthy human volunteers who were experimentally infected with Plasmodium falciparum, we studied vWF secretion and proteolysis as well as the relationship between changes in circulating platelet numbers and plasma levels of vWF and activated vWF. RESULTS: Platelet numbers started to decrease between days 7 and 9 after infection, which corresponded to the earliest phase of blood-stage infection. With the decrease in platelet numbers, levels of vWF, vWF propeptide (markers of chronic and acute endothelial cell activation, respectively), and activated vWF (exposing the glycoprotein Ib alpha ...
Type and quantity of replacement treatment, together with haematological and immunological parameters were determined in 37 boys with severe haemophilia A and 41 children with other bleeding disorders. The quantity of factor VIII concentrate given to boys with severe haemophilia A (mean U/year) showed a significant inverse correlation with total white cell counts, lymphocyte counts, platelet counts, and the ratio of monoclonal antibody defined T lymphocyte subsets, T4 and T8 (T4:T8). Of the boys with severe haemophilia A, 49% had inversed T4:T8 ratios and 24% had thrombocytopenia. Treatment with high dose factor VIII concentrate (more than 25 000 U/year) was associated with low platelet counts, low lymphocyte counts, low T4:T8 ratios, and hypergammaglobulinaemia. In ...
Platelet storage pool deficiencies are rare platelet abnormalities that cause a mild to moderate bleeding disorder. Platelet storage pool deficiencies consist of a number of disorders characterized by a reduction in the number and content of certain types of platelets, called dense granules and alpha granules. The dense granules in platelets serve as a "storage pool" for adenosine triphosphate (ATP), adenosine diphosphate (ADP), serotonin, calcium, and pyrophosphate, which are secreted when platelets are activated. It is thought that the reduced release of ADP may result in the prolonged bleeding times ...

Approach and Results-Among various ABC transporters, ABCB6 was highly expressed in megakaryocyte progenitors, exhibiting the same pattern of expression of genes involved in heme synthesis pathway. Transplantation of Abcb6−/− bone marrow into Ldlr−/− recipient mice resulted in expansion and proliferation of megakaryocyte progenitors, attributable to increased reactive oxygen species production in response to porphyrin loading. The enhanced megakaryopoiesis in Abcb6−/− bone marrow-transplanted mice was further illustrated by increased platelet counts, mean platelet volume, and platelet activity. Platelets from Abcb6−/− bone marrow-transplanted mice had higher levels of chemokine (C-C motif) ligand 5, which was associated with increased plasma chemokine (C-C motif) ligand 5 levels. There were also increased ...

The present study demonstrates that in type 2 DM patients with CAD receiving maintenance aspirin and clopidogrel therapy, the presence of moderate/severe CKD is associated with higher degrees of platelet reactivity compared with patients with normal renal function/mild CKD. In particular, after adjustment for potential confounders, patients with creatinine clearance ,60 ml/min had an almost 4-fold increase in the likelihood of showing high platelet reactivity after ADP stimuli and over a 2-fold increase in high platelet reactivity after collagen stimuli. Importantly, these patients with high platelet aggregability also have increased markers of platelet activation. Overall, these findings are indicative not only of dysfunctional purinergic signaling mediated ADP receptors but also of the presence of a hyper-reactive ...

The control group consisted of age-and sex-matched 70 patients without any retinal vascular occlusion. Statistical comparison ...
Thrombocytopenia - The blood also contains cells called platelets. It is their function to clot the blood when bleeding occurs. Normally, platelet counts are above 150,000 per microliter. In about 35% of patients with Shwachman-Diamond syndrome this count is below that number; this is called thrombocytopenia. Easy bruisability is one indication of thrombocytopenia, but severe bleeding is unusual. Precautions may be required before dental work or surgery, and platelet transfusions or medications may be necessary to diminish the risk of abnormal bleeding ...

Our finding that mean platelet component is lower in acute myocardial infarction than in unstable angina, reflecting greater platelet activation, confirms the central role of thrombogenicity in the pathogenesis of acute coronary syndromes. Indeed, platelet activation was an independent predictor of the mode of presentation and, even in the subgroup of patients with unstable angina at high risk of future events, platelet activation was significantly lower than in those with myocardial infarction.. Some studies have not found a difference in platelet activation between unstable angina and myocardial infarction. However, Garlichs and colleagues2 found greater expression of the CD40 ligand in unstable angina than in myocardial infarction. This appears counterintuitive but may reflect greater hydrolysis and ...

Bernard-Soulier syndrome, also known as hemorrhagiparous thrombocytic dystrophy, is a rare disorder that prevents a person from being able to stop bleeding after an injury or surgery. A portion of our blood is made up of platelets, which are cells that help blood to clot and therefor stops bleeding. While people affected by Benard-Soulier syndrome have large platelets, they do not have enough. This means that something as small as a paper cut will not clot and stop bleeding for hours. Other symptoms of people affected with Bernard-Soulier syndrome are bleeding gums (the area around your teeth), easy bruising, and heavy menstrual periods. Type A Bernard-Soulier syndrome is different from others because of the specific gene that is affected. Talk with your doctor to find the best treatment if you or a loved one has been diagnosed with Bernard-Soulier syndrome ...
To delineate the critical top features of platelets necessary for balance and formation of thrombi, thromboelastography and platelet aggregation measurements were employed in whole blood of normal individuals and of those with Bernard-Soulier Syndrome (BSS) and Glanzmanns Thrombasthenia (GT). generation of stable thrombi, a potentially significant feature in individual medical results. Introduction An initial step in thrombus formation in the hurt vascular endothelium is the adhesion of platelets to shown subendothelial elements, e.g., von Willebrand Aspect (vWF), under high prices of shear, via the connections from the platelet glycoprotein (GP) 1b/V/IX receptor complicated with subendothelial vWF [1]. This tethering of platelets after that promotes their firmer binding to subendothelial collagen (COL) fibres via ...
Our study identifies distinct clinical, laboratory, and outcome differences between ticlopidine- and clopidogrel-associated TTP. More than 90% of the ticlopidine-associated TTP cases develop after more than 2 weeks of thienopyridine use. Among these patients, severe thrombocytopenia and preserved renal function at diagnosis is common, ADAMTS13 activity levels are frequently ,15%, and survival is 86% if TPE is administered versus 46% if TPE is not used. These findings are similar to those reported previously for idiopathic TTP cases with severely deficient ADAMTS13 activity levels (16,23,25). In contrast, three-quarters of the clopidogrel-associated TTP cases develop after 2 weeks or less of thienopyridine use. These patients are characterized by mild thrombocytopenia and renal insufficiency at diagnosis, ADAMTS13 activity levels ,15%, and survival rates that are similar with versus without TPE (72.4% and 66.7%), findings that are similar to those reported previously for TTP cases with ADAMTS13 ...
A 42-yr-old woman, at 38 weeks gestation of her fourth pregnancy (gravida 4, para 3) and obese (110 kg), experienced spontaneous onset of contractions. Her pregnancy was complicated by diet-controlled gestational diabetes and mild preeclampsia. Her platelet count on admission was 220,000/ml. An epidural was requested for labor analgesia and was placed without incident. The initial dosing of the epidural included a 2-ml, 2% lidocaine subarachnoid test dose followed 5 min later by a 5-ml, 2% lidocaine intravenous test dose; both test doses were considered negative. An appropriate bilateral sensory and mild motor block developed and an infusion of 0.1% bupivacaine with fentanyl 2 mcg/ml was initiated at 10 ml/h, producing excellent labor analgesia. Approximately 1 h after epidural placement, thoracic dermatomal levels to cold were confirmed at the umbilicus and the patient had a moderate lower extremity motor block. Ultrasound examination by ...
