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 was closely linked to both mean platelet volume (MPV) and platelet count (PLT) (PDW = 79.5-0.005 PLT -3.5 MPV; r = 0.848, ...

DU PLESSIS, L.. Blood platelet counts, morphology and morphometry in lions, Panthera leo. Onderstepoort j. vet. res. [online]. 2009, vol.76, n.3, pp.317-321. ISSN 2219-0635.. Due to logistical problems in obtaining sufficient blood samples from apparently healthy animals in the wild in order to establish normal haematological reference values, only limited information regarding the blood platelet count and morphology of free-living lions (Panthera leo) is available. This study provides information on platelet counts and describes their morphology with particular reference to size in two normal, healthy and free-ranging lion populations. Blood samples were collected from a total of 16 lions. Platelet counts, determined manually, ranged between 218 and 358 x 109/l. Light microscopy showed mostly activated platelets of various sizes with prominent granules. At the ultrastructural level the platelets revealed typical mammalian platelet morphology. However, morphometric analysis revealed a ...

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 with thrombocytopenia and with normal platelet values. The results of 351 CBCs processed in an automated veterinary haematology counter Sysmex® pocH-100iV Diff were analysed. Two groups of dogs were established, those with thrombocytopenia (45) and those with ...

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 calculated, keeping in view the calculated cut off value and endoscopy findings ...

CLINICAL QUESTION: What is the optimal platelet count threshold for prophylactic platelet transfusions to minimize bleeding, platelet use, and adverse clinical outcomes in thrombocytopenic patients with hematological malignant neoplasms? BOTTOM LINE: Maintaining a higher platelet count threshold (≤20 × 109/L or ≤30 × 109/L) was not associated with less bleeding than the current standard (≤10 × 109/L), but required more platelet transfusions (low-quality evidence).

A pilot study showed that the ratio of CEC to platelet count (CEC/PC) was effective in predicting cirrhosis. Therefore, we evaluated CEC/PC in a larger cohort of patients, correlated it with cirrhosis, and compared its operating characteristics with previously described biomarker for cirrhosis, the AST/platelet ratio index (APRI). Methods: Fifty-three patients with cirrhosis, 20 matched healthy ...

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 counts.. When encountering thrombocytosis in the acute setting, the first step is to see if the patient had thrombocytosis before. ...

Platelet activation and consumption are common in critically ill patients and are associated with poorer prognosis. Mean platelet volume is a simple surrogate for platelet activation, with higher MPV being associated with worse clinical condition on a large array of clinical diagnoses. We therefore aimed to investigate associations between changes in platelet count and mean platelet volume (MPV) with prognosis and inflammatory cytokine values in critically ill patients. This study prospectively included 84 critically ill patients. Patients were stratified into four groups according to proportional changes in MPV (ΔMPV24h) and platelet count (ΔPlat24h) in the first 24 hours after admission. Mortality between groups was compared using the χ2 test. Logistic regression was performed using hospital mortality as outcome and Simplified Acute Physiology Score (SAPS 3), ΔPlat24h and ΔMPV24h as covariates. Concentrations of the following inflammatory mediators were measured using Miliplex® technology: IL1β

The lungs contribute in the final maturation of the circulating platelets, and some studies suggested that chronic lung disease (CLD) could impair circulating platelets maturation or count. Our aim was to study the validity of platelet count (PLT), mean platelet volume (MPV), and plateletcrit (PCT) as simple tools to assess chronic lung disease severity or predict its course. In 39 pediatric patients with CLD, we showed a significant rise in PLTs and PCT and a significant lower MPV when compared to normal controls (P values 0.003, 0.010, 0.004, respectively). Also, a significant positive correlation was detected between the C reactive protein (CRP) level and both the PLTs and PCT (r 0.327, 0.363 respectively) in addition to a significant reduction in MPV level in relation to the age of disease onset (P value 0.031). This study disagrees with the postulation that chronic lung disease could lead to the reduction of circulating platelets and emphasizes the role of increased platelets count and decreased

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 due to impaired production as in aplastic anemia. In addition, low MPV can correlate with abnormally small platelet size, sometimes a symptom of a spectrum referred to as Wiskott-Aldrich Syndrome (WAS), caused by a genetic mutation of the WAS gene. A typical ...

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 as to limit the use of this drug in clinical practice ...

It may be easy to say that no individual worldwide has never suffered from common colds. But when the illness is associated with streptococcus along with being improperly treated, it can lead to the development of valvular heart diseases. These diseases can make a person become vulnerable to the development of abnormal blood clots in the body.. There are several factors that can cause abnormal blood clotting in a person which can be damaging and life threatening. In order to prevent blood clots from harming the person, heparin use is usually suggested.. The use of heparin is a known and established rare causative factor associated to the development of thrombocytopenia in pregnancy. The development of low platelet count that results from the use of heparin is a condition referred to as Heparin-induced thrombocytopenia.. Considering that there are significant reasons where use of heparin is needed in pregnant woman, it puts them at risk to display a low platelet count.. When heparin is introduced ...

During thrombopoiesis, maturing megakaryocytes (MKs) migrate within the complex bone marrow stromal microenvironment from the proliferative osteoblastic niche to the capillary-rich vascular niche where proplatelet formation and platelet release occurs. This physiologic process involves proliferation, differentiation, migration, and maturation of MKs before platelet production occurs. In this study, we report a role for the glycoprotein PECAM-1 in thrombopoiesis. We show that following induced thrombocytopenia, recovery of the peripheral platelet count is impaired in PECAM-1-deficient mice. Whereas MK maturation, proplatelet formation, and platelet production under in vitro conditions were unaffected, we identified a migration defect in PECAM-1-deficient MKs in response to a gradient of stromal cell-derived factor 1 (SDF1), a major chemokine regulating MK migration within the bone marrow. This defect could be explained by defective PECAM-1(-/-) MK polarization of the SDF1 receptor CXCR4 and an increase

However, its use as additive in cell culture media showed inconsistent results on cell proliferation, and the inconsistent results may be due to variability of platelet counts or growth factor content. Standard protocols are lacking for the preparation of PC before it is applied as additive in cell culture media. The growth factor content of PC can be released by freeze-thaw cycles, which range from one to three cycles before use for cell culture media. This study aimed to measure base-line platelet counts and growth factor levels and compare to platelet counts and growth factor levels after one, two and three ...

Thrombocytopenia cases that are particularly resistant may require surgery called splenectomy, where the doctor removes the spleen from the body. Although the function of the spleen is not 100% understood, researchers show that it functions as a filter for the blood, and removes old red blood cells and platelets from the blood stream.. In some cases, the spleen becomes enlarged and stores more than the normal amount of what should only be taken from circulating platelets. This leads to thrombocytopenia. A splenectomy surgery is usually the most preferable low platelet count treatment option to cure the dysfunction; but, doctors generally tries first to use more conservative treatment options, considering that there is no way to undo splenectomy.. On average, splenectomies are successful for about 66 percent of the time. But, over time, it is still possible for thrombocytopenia to recur. People younger than 40 who have undergone splenectomy have a better chance to increase their number of ...

Answer (1 of 3): Low platelet count is known as thrombocytopenia. Symptoms of thrombocytopenia include excessive bleeding, bruising that is caused easily, and bleeding that is caused easily. Platelets are responsible for making a persons blood clot. This occurs when the platelets stick together and stick against the wall of the vessel or capillary. Platelet count can be affected by a persons race or environmental conditions. There are different conditions that can cause low platelet counts. Inherited diseases such as Benard Soulier syndrome or May Hegglin anomaly can cause low platelet counts resulting in heavy bleeding in even small skin lesions. Some people have low platelet count because their body does not produce enough platelets naturally. This can be due to some types of cancer (such as bone marrow cancers,) alcoholism, viral infections, inherited disorders, vitamin B12 deficiency, folic acid deficiency, osteoporosis or myelofibrosis. Some people acquire thrombocytopenia through platelets being

Endoscopic detection of esophageal varices [EV] especially the high risk esophageal varices [HREV] is recommended in cirrhotic patients. There are several studies about non-invasive markers to predict the presence of EV. The aim of this study was to evaluate platelet count to spleen diameter [P/D] ratio and platelet count to spleen area [P/A] ratio as predictors for EV and HREV in patients with liver cirrhosis. This prospective study included 100 cirrhotic patients without previous variceal hemorrhage or endoscopic intervesion. Biochemical, imaging and endoscopic findings were collected in all patients. Several parameters including P/D and P/A ratio were measured and their association with the presence of EV and HREV was tested. The results showed that only P/D and P/A ratios were found to be independent predictors for the presence of EV and HREV in multivariant analysis. For prediction of the EV formation in cirrhotic patients, P/D ratio at value

One interesting report was an update about the drug romiplostin (Nplate®) which has been FDA-approved for patients with idiopathic thrombocytopenic purpura (ITP). Patients with ITP have a low platelet count, not because of a bone marrow problem, but due to an autoimmune problem in which the immune system is attacking the platelets. This drug had been earlier studied in patients with MDS who also have a low platelet count and in the largest study, it was found that romiplostin did improve platelet counts in about 40 to 50% of MDS patients with low platelet counts. This is good news, since we now have a drug that works for platelets in the way that growth factors like erythropoietin (Procrit®) or darbepoetin (Aranesp®) work for low red blood cell counts. Romiplostin can be considered a platelet growth factor, also called a thrombopoietic growth factor (TPO). The problem was that while the randomized Phase 2 study was in progress, the data safety and monitoring board noticed that the patients ...

Myelodysplastic Syndrome (MDS) is a disease of the bone marrow characterized by anemia,neutropenia, and thrombocytopenia (low red blood cell, white blood cell, and platelet counts). MDS patients with thrombocytopenia who fail standard therapies require regular platelet transfusions which are expensive and inconvenient, and are a risk for further serious bleeding complications. The new treatment of MDS using azacitidine has shown to increase the survival rate of MDS patients including to improve platelet production over time. However,in the early cycles of treatment with azacitidine,the low platelet counts tend to exacerbate before they provide any clinical benefit..

Background Thrombocytosis (raised platelet count) is an emerging risk marker of cancer, but the association has not been fully explored in a primary care context.. Aim To examine the incidence of cancer in a cohort of patients with thrombocytosis, to determine how clinically useful this risk marker could be in predicting an underlying malignancy.. Design and setting A prospective cohort study using Clinical Practice Research Datalink data from 2000 to 2013.. Method The 1-year incidence of cancer was compared between two cohorts: 40 000 patients aged â?¥40 years with a platelet count of ,400 Ã- 109/L (thrombocytosis) and 10 000 matched patients with a normal platelet count. Sub-analyses examined the risk with change in platelet count, sex, age, and different cancer sites.. Results A total of 1098 out of 9435 males with thrombocytosis were diagnosed with cancer (11.6%; 95% confidence interval [CI] = 11.0 to 12.3), compared with 106 of 2599 males without thrombocytosis (4.1%; 95% CI = 3.4 to ...

Persons with leukemia are sometimes treated by replacing cancerous blood cells with early forms of normal blood cells taken from healthy persons. This process is called stem-cell transplantation. Chronic graft-versus-host disease (GVHD) is a common complication of stem-cell transplantation in which the transplanted cells attack the patients own tissues. Antibodies, which are made in a type of cell called B cells, are substances that normally help the body to fight off infection and get rid of foreign substances. When antibodies are directed against the bodys own cells, they are called autoantibodies. Chronic GVHD is thought to interfere with the regulation of the transplanted B cells so that they start to make the autoantibodies that damage body tissues. One possible consequence of chronic GVHD is a low platelet count (thrombocytopenia). Platelets are tiny cells in the bloodstream that are important in blood clotting, and patients with thrombocytopenia are therefore at risk for bleeding. ...

Two years ago, I felt some pain in the lymph glands under my jaw. The sonogram showed that my nodes were insignificantly reactive. My doctor told me to have a reqular blood test and it turned out that I had a low platelet count as well (80,000). Ive had a lot of tests since then and the number is going down every time! Its 45000 now. Almost all the results are normal except for platelets and some protein called Beta 2 microglobulin. My B2M was 2.17 mg/L in the first test, 9 months ago. After 6 months it increased to 2.23, and now its about 2.3. I asked my doctor if the result of B2M was important amd he answered No! Saying its not that high, and that they consider it when it, for example, doubles! One more thing that was not in its normal reference range when I first had the test was CMV IgG (126 and a few days later 230). My doctor has asked me to have another test in three months to see what will happen to the platelets, and said if it gets worse Im gonna have to go through a bone ...

We have hypothesized that androgen-mediated thrombocytosis promotes aggressive epithelial ovarian cancer biology. To test this hypothesis, we studied AR transactivation function indirectly through genotype analysis in a hospital-based cohort of women with epithelial ovarian carcinomas and examined clinical and pathologic findings in the context of preoperative platelet counts. Platelet expression of polymorphic ARs that correlate with transactivation function may differentially mediate release of angiogenic factors that function in ovarian cancer biology. We identified a statistically significant relationship between a short AR allelotype and preoperative thrombocytosis and found that the combination of short AR allelotype and thrombocytosis predicted decreased progression-free and overall survival. This combination was the sole independent predictor for suboptimal cytoreduction at initial exploratory surgery and approached statistical independence in multivariate analysis as a predictor for ...

Our data demonstrate thrombocytosis is associated with significantly increased 1-year mortality following admission with AECOPD. Thrombocytosis was associated with significantly increased inhospital mortality and correlated with markers of type II respiratory failure and exacerbation severity. Thrombocytosis was not associated with chronic comorbidities such as ischaemic heart disease, diabetes or renal impairment.. As with all association studies, our data cannot prove causation and the underlying mechanisms between thrombocytosis and death are not clear. McDonald et al demonstrated that 1-4 days of hypoxia resulted in thrombocytosis, and hypothesised that shedding of immature platelets from megakaryocytes was the mechanism.9 This hypothesis is supported by Wedzicha et al who established a negative correlation between mean platelet volume (MPV) and arterial oxygen tension,10 given that immature reticulated platelets have a larger MPV than mature circulating platelets. Larger, immature ...

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 now been split into four smaller reviews looking at these questions individually; this review compares prophylactic platelet transfusion thresholds. Objectives To determine whether different platelet transfusion thresholds for

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. Patients were randomly assigned in a 2:1 ratio of eltrombopag:placebo by a validated randomisation system. After 3 weeks, patients with platelet counts less than 50 000 per microL could increase study drug to 75 mg. The primary endpoint was the proportion of patients achieving platelet counts 50 000 per microL or more at day 43. All participants who

Severe thrombocytopenia should be corrected by prophylactic platelet transfusion prior to central venous catheter (CVC) insertion, according to national and international guidelines. Even though correction is thought to prevent bleeding complications, evidence supporting the routine administration of prophylactic platelets is absent. Furthermore, platelet transfusion bears inherent risk. Since the introduction of ultrasound-guided CVC placement, bleeding complication rates have decreased. The objective of the current trial is, therefore, to demonstrate that omitting prophylactic platelet transfusion prior to CVC placement in severely thrombocytopenic patients is non-inferior compared to prophylactic platelet transfusion. The PACER trial is an investigator-initiated, national, multicentre, single-blinded, randomised controlled, non-inferior, two-arm trial in haematologic and/or intensive care patients with a platelet count of between 10 and 50 × 109/L and an indication for CVC placement. Consecutive

Aim: To evaluate the combined and individual effects of thioxanthene containing antipsychotic and anti-platlet drug on Mean Platelet Volume (MPV) and Platelet Distribution Width (PDW) in rats.. Methods: This investigational study comprised of 100 albino rats of both sexual orientation, they were of 300 g to 350 g. We got ten groups, in which each group consisted of 10 rats (n=10).Ozagrel was used as anti-platelet and Zuclopenthixol was used as thioxanthene containing antipsychotic. Rats were treated with defined doses of Ozagrel and thioxanthene containing anti-psychotic (Zuclopenthixol) alone and in joined for three weeks (21 days). Blood test at 0, seventh, fourteenth and last day of study were taken. Mean Platelet Volume and Platelet Distribution Width were estimated from blood tests by using standard research center procedure. Results were accumulated and abridged by applying statistics. Correlation was framed between all days incentive to zero day values.. Results: Anti-psychotic drug and ...

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 each subject were recorded from the VA electronic medical record at the closest possible time period (within ≤6 months) to the date of coated-platelet sample. Correlations between each parameter and coated-platelet levels were determined and those reaching significance at p≤0.1 were included in a multiple regression model with LDL and systolic blood pressure (SBP), variables previously ...

Abstract:. Aims and Objective: To determine the role of Moringa oleifera on total platelet count alterations (T-PC) in rats treated with cadmium. Materials and Methods: In the present study female adult Wistar Albino rats, (180-200) gm were divided into, Group I-normal control, Group II-pretreated control, group III-cadmium treated , group IV- pre-treated with Moringa oleifera leaf extract (MOE) and then administered oral cadmium for a day, with n=6 each Results: Indicate that the pre-treatment with MOE (100 mg/kg/bw) prior to cadmium infusion augmented the level of total platelet count (p≤0.001) as compared to the cadmium-exposed group, which might have a role in clotting mechanisms also. Conclusion: Moringa oleifera extract has a beneficial effect on platelet count in cadmium-induced animal model.. ...

Inflammatory bowel disease (IBD)-like colitis is a known entity in glycogen storage disease (GSD) type 1b patients. The mean age of the reported cases with IBD-like colitis was 12 +/- 5 years, and all had absolute neutrophil count (ANC) less than 1,000 cells/mu l. We report a three-year-old girl with GSD type 1b that was dignosed by mutation analysis. The patient was hospitalized with fever, diarrhea, and perioral and anal ulcers. Colonoscopy was performed and IBD-like colitis was diagnosed. The patient had elevated platelet count beyond the age of three months, but IBD-like colitis was diagnosed at three years of age. An elevated platelet count may be a warning sign for the IBD-like colitis in young patients with GSD type 1b. ...

What is Thrombocytopenia? Low Platelet Count! Steps to Regain a Healthy Count! What is Thrombocytopenia? It is a Low Platelet Count. There are many factors that can cause thrombocytopenia. The condition can be inherited or acquired. Inherited means your parents pass the gene for the condition to you. Acquired means you arent born with the condition, but you develop it. Sometimes the cause of thrombocytopenia isnt known. In this article I share with you the steps that you can take to regain a healthy coun

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 called Neumega®. Clinical studies have shown that Neumega® prevents thrombocytopenia and decreases the need for platelet transfusions in some patients at high risk for developing a low platelet count.. Platelet transfusion: A platelet transfusion is the addition of platelets into your blood from an outside source, such as a blood bank. Platelet transfusions ...

The relationship between the percent phagocytosis of platelets by differentiated THP-1 cells was examined using flowcytometry and the peripheral platelet counts as well as platelet-associated IgG (PAIgG) in 36 patients with secondary dengue virus (DV) infections. The percent phagocytosis and the levels of PAIgG were significantly increased in these patients during the acute phase compared with the healthy volunteers. The increased percent phagocytosis and PAIgG found during the acute phase significantly decreased during the convalescent phase. An inverse correlation between platelet count and the percent phagocytosis (P = 0.011) and the levels of PAIgG (P = 0.041) was found among these patients during the acute phase. No correlation was found, however, between the percent phagocytosis and the levels of PAIgG. Our present data suggest that accelerated platelet phagocytosis occurs during the acute phase of secondary DV infections, and it is one of the mechanisms of thrombocytopenia in this disease.

A review in people with blood cancers receiving intensive chemotherapy or a stem cell transplant found that overall giving platelet transfusions when the platelet count is less than 10 x 109/L reduced the number of bleeding events and days with significant bleeding.[15] However, this benefit was only seen in certain patient groups, and people undergoing an autologous stem cell transplant derived no obvious benefit.[15] Despite prophylactic platelet transfusions, people with blood cancers often bleed, and other risk factors for bleeding such as inflammation and duration of thrombocytopenia should be considered.[13]. There is little evidence for the use of preventative platelet transfusions in people with chronic bone marrow failure, such as myelodysplasia or aplastic anemia.[16] Multiple guidelines recommend prophylactic platelet transfusions are not used routinely in people with chronic bone marrow failure, and instead an individualised approach should be taken.[11][10][13]. Several studies have ...

Review question We evaluated the evidence about whether giving agents that can replace, or reduce platelet transfusion (artificial platelets, platelet-poor plasma, fibrinogen concentrate, recombinant activated factor VII (rFVIIa), recombinant factor XIII (rFXIII), recombinant interleukin (rIL)6 or rIL11, desmopressin (DDAVP), thrombopoietin (TPO) mimetics or antifibrinolytic drugs), to people with a low platelet count prevents bleeding and whether these alternative agents are associated with side effects. Our target population was people with bone marrow disorders which prevent them from producing enough platelets. We excluded people undergoing intensive chemotherapy or stem cell transplantation.. Background People with low platelet counts due to bone marrow disorders are vulnerable to bleeding which may be severe or life-threatening. In order to treat, or prevent bleeding, they are often given platelet transfusions. However, platelet transfusions are associated with risks such as infection and ...

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 manifestations of HCV infection. ...

INTRODUCTION: in recent years, it is suggested that platelet histogram indices, such as mean platelet volume (MPV) may be related to the activity of rheumatoid arthritis (RA). The aim of this study was to assess relationship between MPV and activity of rheumatoid arthritis. METHODS: sixty consecutive patients fulfilling the American College of Rheumatology (ACR) criteria for RA were recruited from the rheumatology outpatient clinics in Semnan, Iran. Current disease activity score (DAS-28 score) was assessed at baseline, 2 months and 4 months after the admission time and beginning of the treatment schedule. Complete blood count (including MPV), C-reactive protein (CRP) and ESR were measured in each visit. MPV was analyzed by the Cell Dyne 3500 automated blood cell counter. RESULTS: there was a significant reduction in DAS-28 score within 4 months of total assessment (from 4.47 2.24 versus 3.18 1.55) (p < 0.001). There was no significant difference in MPV levels at the three study time points. No

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 endothelium, less than the number of platelets in a single concentrate. However, many clinical conditions can adversely affect platelet recovery and platelet survival in the circulation. Prophylactic platelet transfusion is an important part of supportive ...

This is the protocol for a review and there is no abstract. The objectives are as follows: To compare the relative efficacy of different treatments for thrombocytopenia (artificial platelet substitutes, platelet-poor plasma, fibrinogen, rFVIIa, rFXIII, thrombopoietin mimetics, antifibrinolytic drugs or platelet transfusions) in patients with chronic bone marrow failure and to derive a hierarchy of potential alternate treatments to platelet transfusions.

AU - Wityk, Robert J.. PY - 2003/7. Y1 - 2003/7. N2 - Impaired platelet function has been associated with an increased propensity for intracerebral hemorrhage (ICH). The role of platelet count and dysfunction in spontaneous ICH (SICH) is poorly understood. We tested the hypotheses that patients with SICH have subtle platelet dysfunction associated with ICH progression and larger ICH size. In a retrospective case series, we compared platelet counts in patients with SICH with age-matched controls with neuromuscular disorders admitted to a Neurosciences Critical Care Unit (NCCU). In a subset of patients, platelet function was measured within one week of ICH. Computerized tomography (CT) scans were performed within 24 hours of the event and ICH volume determined by the ABC/2 method. Comparison of 43 patients ...

UNLABELLED Elderly patients represent a high risk category among subjects with atherosclerosis, due to the presence of comorbidities and suboptimal response to antiplatelet drugs. Mean platelet volume (MPV) has been indicated as a marker of platelet reactivity, with contrasting data on its role on coronary artery disease. Aim of the present study was to evaluate the impact of age on the MPV and its role on the extent of coronary artery disease (CAD). METHODS Our population is represented by a cohort of 3750 patients undergoing coronary angiography. Elderly were defined according to age ≥ 75 years. MPV was measured at admission. Significant coronary artery disease was defined as a stenosis |50% in at least 1 coronary vessel, while severe CAD was defined as left main and/or three-vessel disease. RESULTS A total of 1170 out of 3750 (31.2%) patients were ≥ 75 years old. Advanced age was associated with female gender (p|0.001), hypertension (p|0.001), renal failure (p|0.001), previous myocardial

BACKGROUND: c-Kit is a proto-oncogene that encodes tyrosine kinase receptor (CD117). Mean platelet volume (MPV) is a useful marker, providing information on platelet function and diameter.

Maternal anti-Ro and anti-La antibodies Associated with complete fetal heart block in 5-10% of cases. Immune (idiopathic) thrombocytopenic purpura • Immune thrombocytopenic purpura (ITP) is a maternal disease characterized by the presence of circulating antiplatelet antibodies. It should be distinguished from alloimmune thrombocytopenia (ATP) in which maternal platelet counts are normal, but antiplatelet antibodies (usually anti-PLA1/2) cross the placenta to cause fetal thrombocytopenia and possibly intraventricular hemorrhage. ATP is analogous to rhesus (Rh) disease of platelets. • Differential diagnosis. Pre-eclampsia, coagulopathy, drugs, gestational thrombocytopenia. • Complications. IgG can cross the placenta and cause fetal thrombocytopenia. However, the correlation between maternal and fetalplatelet counts is poor. Fetal intraventricular hemorrhage in the setting of ITP is rare. • Management. Corticosteroids may be necessary if maternal thrombocytopenia is severe. Intravenous Ig, ...

Polycystic ovary syndrome (PCOS)is closely associated with insulin resistance and hyperinsulinemia as well as with increased incidence in diabetes, hypertension, dyslipidemia and atherosclerosis. Indeed, subjects with PCOS were reported to carry an increased long-term cardiovascular risk, among others. Aiming to correlate the mean platelet volume, the thromboxane A2 level and the PCOS, an observational study was planned. Clinical evaluation of metabolic outcomes in PCOS patients is compared to a placebo group ...

Background Our aim in this study was to investigate whether mean platelet volume (MPV) value could be used as an early marker to predict pelvic inflammatory disease (PID).

A 70-year-old man was admitted with generalized seizures. The initial laboratory evaluation showed normal blood counts (platelet count, 303 109/L) and normal coagulation studies. Dilantin therapy was started and a left parietal hemorrhage was diagnosed. Nine days later, a left lower lobe pneumonia developed that was treated with gentamicin and ceftriaxone. On day 19, because of persistent fever, this antibiotic treatment was discontinued and mezlocillin therapy was started. The platelet count on that day was 388 109/L. On days 20 to 22, platelet counts were between 368 and 421 109/L; blood counts were not checked on days 23, 24, and 25. On day 26, the platelet count was 1 109/L, with a normal leukocyte count, hemoglobin concentration, prothrombin time, and partial thromboplastin time. The patient was clinically stable with no overt bleeding. Six units of random donor platelet concentrates were transfused; the platelet count 1 hour after transfusion was 83 109/L. Therapy with mezlocillin and ...

GlaxoSmithKline reported positive results from two phase II trials of Promacta - a non-peptide thrombopoietin receptor agonist (platelet growth factor) which can stimulate the growth and differentiation of bone marrow cells that priduce blood platelets - for the treatment of chronic hepatitis C-associated thrombocytopenia and chronic Idiopathic thrombocytopenic purpura (ITP). The first study was an international, multicenter, double-blind, randomized, placebo-controlled, dose-ranging study. A total of seventy-four HCV-infected subjects with platelet counts between 20,000 and 70,000/mL were enrolled. The subjects received Promacta (30mg, 50mg, or 75mg daily) or placebo for four weeks (pre-antiviral phase).. The primary endpoint was platelet count increase to greater than or equal to 100,000/mL at week four. The subjects could then initiate antiviral therapy and continue Promacta or placebo for 12 additional weeks (antiviral phase).. The primary endpoint was reached by 75%, 79% and 95% of subjects ...

Circulating platelets consist of subpopulations with different age, maturation state and size. In this review, we address the association between platelet size and platelet function and summarize the current knowledge on platelet subpopulations including reticulated platelets, procoagulant platelets and platelets exposing signals to mediate their clearance. Thereby, we emphasize the impact of platelet turnover as an important condition for platelet production in vivo. Understanding of the features that characterize platelet subpopulations is very relevant for the methods of platelet concentrate production, which may enrich or deplete particular platelet subpopulations. Moreover, the concept of platelet size being associated with platelet function may be attractive for transfusion medicine as it holds the perspective to separate platelet subpopulations with specific functional capabilities.

Data from a Phase II study of eltrombopag, an oral investigational drug that increases the production of platelets, demonstrate that the compound was effective in increasing platelet counts in patients with chronic Immune Thrombocytopenic Purpura (ITP), a disorder characterized by episodes of frequent spontaneous bruising, mucosal bleeding, and in severe cases intracranial hemorrhage, and acute episodes of severe bleeding.

Results: During the study period, 2667 patients were admitted to the NICU and 395 (14%) had thrombocytopenia during hospitalization. The rate of IVH was 7.3%. Multiple logistic regression analysis showed that although lower platelet counts were associated with a higher IVH rate, the effects of respiratory distress syndrome (RDS), sepsis, and patent ductus arteriosus (PDA) were more prominent than the degree of thrombocytopenia. Thirty patients (7%) received PT, and these patients showed a significantly higher mortality rate than that of their non-PT counterparts (p , 0.001). In addition, it was found that the use of PMI-based criteria for PT in our patients would reduce the rate of PT by 9.5% (2/21 ...

A method for determining platelet activation by utilizing numeric counts of platelets before a sample of platelets has been activated and after the activatable platelets are activated with a platelet activation agonist and using the difference between such counts as an, indication of the platelet activity of the sample. There is also disclosed a method for using the electronic impedance cell counting technique for determining platelet activation wherein EDTA is used as a preservative by counting the platelets in an EDTA preserved sample using an electronic impedance cell counting technique and subtracting from that number the number of platelets remaining after the activatable platelets in a second sample have been activated with a platelet agonist in the absence of EDTA and using that difference as a measure of platelet activity.

Platelets are the first responders to a bleeding incident. If the full platelet force does not arrive on the scene, bleeding will continue and peticheae, bruises, and perhaps even hemorrhaging will occur. A decreased platelet force (thrombocytopenia) may be caused by several diseases or disorders. On the other hand, a low platelet count may not actually mean that the full platelet force is not available to respond. It is up to the laboratory professional to determine if there is anything in the collection procedure that has artificially produced this low count. This course will increase your understanding of various authentic causes of thrombocytopenia and will alert you to various causes of spurious thrombocytopenia that you, as a medical laboratory scientist should be able to recognize and correct to prevent false reporting of thrombocytopenia..

secondly, his platelet levels are dropping to dangerously low levels. a normal platelet count might be between 150,000 and 200,000 and his results from this afternoon came back at 70,000. this is such a low level that his neonatologist immediately ordered a new test to rule out a lab error. the second test indicated that his platelet count was 60,000. the elevated direct bilirubin and decreased platelets are cause for enough concern that hes being put on increased surveillance which means theyll run blood tests more frequently ( which also means that he might need another transfusion since they need to draw blood for the tests ). as always, there are multiple Educated Guesses that could possibly explain the lab results. his increasingly elevated direct bilirubin levels might be due to his latest blood transfusion, since transfused blood cells die more quickly than regular blood cells and direct bilirubin can be a by-product of the red blood cell death. his diminished platelets might be ...

Platelet Rich Plasma (PRP) / Stem Cell Prolotherapy is based on the same theory and methodology as dextrose Prolotherapy, however, the solution used is a high-density concentration of the patients circulating platelet levels isolated and concentrated by bidirectional centrifugation. Enhanced healing capability is possible when platelet concentrations are increased within injured or damaged tissue. For many years, the importance of platelets was thought to be formation of plugs, useful in reduction of bleeding in the tissues. It is now recognized that this may represent the least important function served by platelets. Platelets contain a significant number of key signal proteins, growth factors, chemokines, cytokines and other pro-inflammatory bioactive factors that initiate and regulate basic aspects of the inflammatory cascade resulting in natural wound healing. Elevated platelet concentrations are also known to stimulate the proliferation, differentiation and migration of needed ...

Result column: The result column shows counts that fall within the normal range.. Flag column: The flag column shows counts that are lower (L) or higher (H) than the normal range.. Reference Interval (or Reference Range) column: The reference interval shows the normal range for each measurement for the lab performing the test. Different labs may use different reference intervals.. White blood cells: White blood cells help protect individuals from infections. The above CBC report shows that the patients total white cell count is 1.5, which is lower than the normal range of 4.0-10.5. The low white cell count increases the risk of infection.. Differential: This portion of the CBC shows the counts for the 5 main kinds of white cells, either as percentages (the first 5 counts), or as the absolute number of cells (the second 5 counts).. Absolute neutrophil count: Neutrophils are the main white blood cell for fighting or preventing bacterial or fungal infections. In the CBC report, neutrophils may ...

The normal circulating platelet count is maintained within relatively narrow limits (150,000-450,000 platelets/μL in Northern Europeans and 90,000-300,000 platelets/μL in people of Mediterranean descent). This difference is related to an inherited slight variation in individual platelet volume (size). The platelet volume is inversely related to the platelet count, so the mass of circulating platelets is the same for these 2 populations. Approximately one-third of platelets are sequestered in the spleen at any one time. Splenic sequestration of platelets can increase dramatically with splenomegaly. Since a platelet has a lifespan of approximately 9-10 days, some 15,000-45,000 platelets/μL must be produced each day to maintain a steady state. New platelet production is the responsibility of the megakaryocyte, a very large multinucleated cell (10,750 fL) found in relatively small numbers in the marrow (0.1% of marrow cells) (Figure 31-1). As with other hematopoietic cells, megakaryocytes are ...

We have established that our newborn baby with an intracranial haemorrhage has a low platelet count and have debated the likely cause for this.

The babys platelet count is…

After mysterious bruises appeared on her arms, a small cut on her tongue continued to bleed, and each day brought a struggle to maintain the life she knew, Joan went from disbelief through denial and finally learned she had immune thrombocytopenic purpura, ITP. ITP is a chronic autoimmune bleeding disorder, subjecting its victims to a lifetime struggle with low platelet counts and a constant fear of bleeding to death, or so Joan was led to believe.. The usual first line treatment for ITP, a high dose of prednisone, not only failed to help solve Joans bleeding problem, but was instrumental in causing a seizure and a heart condition. When a splenectomy and several other drugs suggested by her hematologist left her depressed, demoralized, with additional conditions to treat, and a platelet count that hovered near zero, she began her own search for a cure.. She experimented with energy medicine, herbs, meditation, and diet changes, applying what she knew from teaching science, seeking the advice of ...

ITP is an autoimmune disease affecting approximately 200,000 people in the United States. It is characterized by low platelet counts because of an increase in destruction and reduction of platelet production. The cause is unknown.. There are two basic types of ITP, acute and chronic. The chronic form has posed the largest challenge to treat and is associated with an increased tendency to bleed as the platelet count drops to a critical low level. All traditional therapies have focused on the destruction component of the disease and include immune modulation with corticosteroids, intravenous immunoglobulin (IVIG), splenectomy, cyclosporine, and in some cases targeted B cell destruction.. Eltrombopag was studied in two (A and B) separate multicenter, randomized, double-blind, placebo-controlled clinical trials involving 231 patients. Approximately 40 percent had had a splenectomy. More than 50 percent had received more than three therapies for their disease. Entry criteria and baseline platelet ...

This is a drug that is already FDA-approved to treat another blood disorder called Immune Thrombocytopenia Purpura (ITP) - a blood condition that occurs when the body makes antibodies against platelets and destroys them very quickly, resulting in low platelet counts. Eltrombopag (Promacta®) was originally developed to treat this condition, and has been available for about six years for that clinical indication. It is a medication that can be taken by mouth that mimics the action of the hormone thrombopoietin, a substance made by the body that is know to be very important to stimulate production of platelets, and thus it is termed a thrombopoietin mimetic. Since then, we designed a pilot trial to test its use in patients with severe aplastic anemia (SAA) who had failed other treatments, which were most often multiple rounds of immunosuppressive therapy. This is known as refractory SAA. When tested in this setting, it was found to not only improve platelet counts in some patients, but also ...

Rigels bleeding disorder drug clears first of two key trials. Rigel Pharmaceuticals Inc said its experimental drug to treat a bleeding disorder met its main goal in the first of two late-stage trials, sending its shares up 12 pct in premarket trade.. The drug, fostamatinib, is being studied to treat chronic immune thrombocytopenia (ITP) in which the immune system attacks and destroys the bodys own blood platelets.. About 18 percent of the 76 adult patients who were treated with fostamatinib achieved a stable platelet response in the study, compared with none on placebo.. Patients typically had an increase in platelet counts to a level above 50,000/uL within the initial weeks of treatment.. ITP patients can suffer extreme bruising, bleeding and fatigue due to low platelet counts. Chronic ITP affects an estimated 60,000 to 125,000 people in the United States.. Rigel said results from the second late-stage trial are expected in October or November.. The company expects to file an application for ...

Several growth factors feature prominently in the control of hematopoiesis. Thrombopoietin, a class I hematopoietic cytokine, plays critical roles in regulating hematopoietic stem cell numbers and also stimulates the production and differentiation of megakaryocytes, the bone marrow cells that ultimately produce platelets. Thrombopoietin interacts with the c-Mpl cell-surface receptor. Recently, several peptide and small-molecule agonists and antagonists of c-Mpl have been reported. We conducted a bioinformatics and molecular modeling study aimed at understanding the agonist activities of peptides that bind to c-Mpl, and developed new potent peptide agonists with low nanomolar activity. These agonists also show very high activity in human CD34+ primary cell cultures, and doubled the mean blood platelet counts when injected into mice. ...

A University of Utah School of Medicine-led study has identified a previously unknown but crucial component in the process to make platelets, a discovery that could help spare multiple myeloma patients from a dangerous side effect of the primary drug (bortezomib) used to treat their cancer.
