Fractionated administration of irinotecan and cisplatin for treatment of lung cancer: a phase I study. (1/2217)

A combination chemotherapy of irinotecan (CPT-11) and cisplatin (CDDP) has been reported to be active for lung cancer. In the previous trial, however, diarrhoea and leucopenia became the major obstacle for sufficient dose escalation of CPT-11 to improve the treatment outcome. We conducted a phase I study to investigate whether the fractionated administration of CDDP and CPT-11 at escalated dose was feasible and could improve the treatment outcome. Twenty-four previously untreated patients with unresectable non-small-cell lung cancer (NSCLC) or extensive disease of small-cell lung cancer (SCLC) were eligible. Both CDDP and CPT-11 were given on days 1 and 8, and repeated every 4 weeks. The dose of CDDP was fixed at 60 mg m(-2) and given by 1-h infusion before CPT-11 administration. The starting dose of CPT-11 was 40 mg m(-2), and the dose was escalated by an increase of 10 mg m(-2). The maximally tolerated dose of CPT-11 was determined as 60 mg m(-2) because grade 4 haematological or grade 3 or 4 non-haematological toxicities developed in six patients out of 11 patients evaluated. Diarrhoea became a dose-limiting toxicity. The objective response rates were 76% for NSCLC and 100% for SCLC. The recommended dose of CPT-11 and CDDP in a phase II study will be 50 mg m(-2) and 60 mg m(-2) respectively.  (+info)

Bronchoconstrictor effect of thrombin and thrombin receptor activating peptide in guinea-pigs in vivo. (2/2217)

1. Several thrombin cellular effects are dependent upon stimulation of proteinase activated receptor-1 (PAR-1) localized over the cellular surface. Following activation by thrombin, a new N-terminus peptide is unmasked on PAR-1 receptor, which functions as a tethered ligand for the receptor itself. Synthetic peptides called thrombin receptor activating peptides (TRAPs), corresponding to the N-terminus residue unmasked, reproduce several thrombin cellular effects, but are devoid of catalytic activity. We have evaluated the bronchial response to intravenous administration of human alpha-thrombin or a thrombin receptor activating peptide (TRAP-9) in anaesthetized, artificially ventilated guinea-pigs. 2. Intravenous injection of thrombin (100 microkg(-1)) caused bronchoconstriction that was recapitulated by injection of TRAP-9 (1 mg kg(-1)). Animal pretreatment with the thrombin inhibitor Hirulog (10 mg kg(-1) i.v.) prevented thrombin-induced bronchoconstriction, but did not affect bronchoconstriction induced by TRAP-9. Both agents did not induce bronchoconstriction when injected intravenously to rats. 3. The bronchoconstrictor effect of thrombin and TRAP-9 was subjected to tolerance; however, in animals desensitized to thrombin effect, TRAP-9 was still capable of inducing bronchoconstriction, but not vice versa. 4. Depleting animals of circulating platelets prevented bronchoconstriction induced by both thrombin and TRAP-9. 5. Bronchoconstriction was paralleled by a biphasic change in arterial blood pressure, characterized by a hypotensive phase followed by a hypertensive phase. Thrombin-induced hypotension was not subject to tolerance and was inhibited by Hirulog; conversely, hypertension was subject to tolerance and was not inhibited by Hirulog. Hypotension and hypertension induced by TRAP-9 were neither subject to tolerance nor inhibited by Hirulog. 6. Our results indicate that thrombin causes bronchoconstriction in guinea-pigs through a mechanism that requires proteolytic activation of its receptor and the exposure of the tethered ligand peptide. Platelet activation might be triggered by the thrombin effect.  (+info)

Primary percutaneous transluminal coronary angioplasty performed for acute myocardial infarction in a patient with idiopathic thrombocytopenic purpura. (3/2217)

A 72-year-old female with idiopathic thrombocytopenic purpura (ITP) complained of severe chest pain. Electrocardiography showed ST-segment depression and negative T wave in I, aVL and V4-6. Following a diagnosis of acute myocardial infarction (AMI), urgent coronary angiography revealed 99% organic stenosis with delayed flow in the proximal segment and 50% in the middle segment of the left anterior descending artery (LAD). Subsequently, percutaneous transluminal coronary angioplasty (PTCA) for the stenosis in the proximal LAD was performed. In the coronary care unit, her blood pressure dropped. Hematomas around the puncture sites were observed and the platelet count was 28,000/mm3. After transfusion, electrocardiography revealed ST-segment elevation in I, aVL and V1-6. Urgent recatheterization disclosed total occlusion in the middle segment of the LAD. Subsequently, PTCA was performed successfully. Then, intravenous immunoglobulin increased the platelet count and the bleeding tendency disappeared. A case of AMI with ITP is rare. The present case suggests that primary PTCA can be a useful therapeutic strategy, but careful attention must be paid to hemostasis and to managing the platelet count.  (+info)

Antithrombotic efficacy of thrombin inhibitor L-374,087: intravenous activity in a primate model of venous thrombus extension and oral activity in a canine model of primary venous and coronary artery thrombosis. (4/2217)

The small molecule direct thrombin inhibitor L-374,087 was characterized across species in an in vitro activated partial thromboplastin clotting time (aPTT) assay and in vivo in rhesus monkey and dog thrombosis models. In vitro in rhesus, dog, and human plasma, L-374,087 concentrations eliciting 2-fold increases in aPTT were 0.25, 1.9, and 0.28 microM, respectively. In anesthetized rhesus monkeys, 300 microgram/kg bolus plus 12 microgram/kg/min and 300 microgram/kg bolus plus 30 microgram/kg/min L-374,087 i.v. infusions significantly reduced jugular vein thrombus extension, with both regimens limiting venous thrombus extension to 2-fold that of baseline thrombus mass compared with a 5-fold extension observed in the vehicle control group. Antithrombotic efficacy in the rhesus with the lower-dose regimen was achieved with 2.3- to 2.4-fold increases in aPTT and prothrombin time. In a conscious instrumented dog model of electrolytic vessel injury, the oral administration of two 10 mg/kg L-374,087 doses 12 h apart significantly reduced jugular vein thrombus mass, reduced the incidence of and delayed time to occlusive coronary artery thrombosis, and significantly reduced coronary artery thrombus mass and ensuing posterolateral myocardial infarct size. Antithrombotic efficacy in the dog was achieved with 1.6- to 2.0-fold increases in aPTT at 1 to 6 h after oral dosing with L-374,087. These results indicate significant antithrombotic efficacy against both venous and coronary arterial thrombosis with L-374,087 with only moderate elevations in aPTT or prothrombin time. The oral efficacy of L-374,087 characterizes this compound as a prototype for the further development of orally active direct thrombin inhibitors.  (+info)

Prospective randomized multicenter study comparing cyclosporin alone versus the combination of antithymocyte globulin and cyclosporin for treatment of patients with nonsevere aplastic anemia: a report from the European Blood and Marrow Transplant (EBMT) Severe Aplastic Anaemia Working Party. (5/2217)

We report the results of the first prospective randomized multicenter study of immunosuppressive treatment in patients with previously untreated nonsevere aplastic anemia (AA) as defined by a neutrophil count of at least 0.5 x 10(9)/L and transfusion dependence. Patients were randomized to receive cyclosporin (CSA) alone or the combination of horse antithymocyte globulin ([ATG] Lymphoglobuline; Merieux, Lyon, France) and CSA. The endpoint of the study was the hematologic response at 6 months. One hundred fifteen patients were randomized and assessable with a median follow-up period of 36 months; 61 received CSA and 54 ATG and CSA. In the CSA group, the percentage of complete and partial responders was 23% and 23%, respectively, for an overall response rate of 46%. A significantly higher overall response rate of 74% was found in the ATG and CSA group, with 57% complete and 17% partial responders (P =. 02). Compared with CSA alone, the combination of ATG and CSA resulted in a significantly higher median hemoglobin level and platelet count at 6 months. Fewer patients required a second course of treatment before 6 months due to a nonresponse. In the CSA group, 15 of 61 (25%) patients required a course of ATG before 6 months because of disease progression, compared with only 3 of 54 (6%) in the ATG and CSA group. The survival probabilities for the two groups were comparable, 93% (CSA group) and 91% (ATG and CSA group), but at 180 days, the prevalence of patients surviving free of transfusions, which excluded patients requiring second treatment because of nonresponse, death, disease progression, or relapse, was 67% in the CSA group and 90% in the ATG and CSA group (P =.001). We conclude that the combination of ATG and CSA is superior to CSA alone in terms of the hematologic response, the quality of response, and early mortality, and a second course of immunosuppression is less frequently required.  (+info)

Thrombopoietin: its role from early hematopoiesis to platelet production. (6/2217)

BACKGROUND AND OBJECTIVE: Thrombopoietin (TPO), also referred to as MpI ligand, is the most potent cytokine that physiologically regulates platelet production. With the availability of sufficient amounts of recombinant forms of the protein, the biological in vitro and in vivo activities of this cytokine have been extensively studied. The objective of this review is to summarize the published data focusing on TPO production and regulation and to discuss the pleiotropic biological action of this hormone. The review also highlights the results so far obtained in preclinical and clinical trials. EVIDENCE AND INFORMATION SOURCES: The material examined in this review includes data published by the author and articles or abstracts published in Journals covered by Medline. The author has contributed to the isolation of TPO, has been working in the field for several years and has contributed original papers on the TPO/MpI system in normal and pathologic situations. STATE OF THE ART: TPO is a hormone constitutively produced by the liver and kidneys. Plasma levels of TPO are regulated through receptor-mediated uptake, internalization and catabolism. First thought to be a lineage dominant factor promoting megakaryocytopoiesis, several lines of evidence indicate that TPO has pleiotropic effects on hematopoiesis. In vitro studies show that TPO alone, or in combination with early acting cytokines, stimulates the proliferation and enhances the expansion of primitive CD34+ CD38- hematopoietic progenitor cells. In vivo studies with c-mpl- and TPO-null mice reveal that the molecule sustains the survival and proliferation of early committed progenitor cells of various type. Preclinical and clinical trials indicate that recombinant TPO molecules increase platelet counts and megakaryocyte numbers in normal or mildly thrombocytopenic states. However, no significant effects of TPO administration on platelet recovery have so far been reported in patients subjected to intensive chemotherapy regimens. Recombinant molecules appear to be safe to administer and very little toxicity is reported. TPO augments the number of erythroid and myeloid committed progenitor cells in marrow, and mobilized stem cells in peripheral blood. PERSPECTIVES: The potential clinical use of TPO is still unclear. With the increased knowledge of the multiple effects of TPO on hematopoiesis, it is expected that future carefully monitored clinical trials will provide more information regarding the eventual benefits of this cytokine in the treatment of thrombocytopenia. At present, one successful application of TPO appears to be its addition in cytokine cocktails used to expand hematopoietic stem cells ex vivo.  (+info)

Patients with thrombocytosis have normal or slightly elevated thrombopoietin levels. (7/2217)

BACKGROUND AND OBJECTIVE: The distinction between clonal and reactive thrombocytoses is a frequent problem and implies different therapeutic options. As thrombopoietin (TPO) is the main regulator of megakaryocytopoiesis and thrombopoiesis, we measured TPO levels in patients with thrombocytosis in an attempt to understand the regulation and potential utility of distinguishing thrombocytoses. DESIGN AND METHODS: Serum TPO levels, platelet counts, mean platelet volume, hemoglobin, erythrocyte sedimentation rate and age were evaluated in 25 patients with clonal thrombocytosis (15 with essential thrombocythemia, 6 with polycythemia vera and 4 with chronic myeloid leukemia) and in 50 patients with reactive thrombocytosis distributed in three groups: 1) patients in post-surgical states; 2) patients with solid tumors; and 3) patients with inflammatory diseases. RESULTS: TPO levels were slightly increased in patients with clonal (135+/-50 pg/mL) and reactive (147+/-58 pg/mL) thrombocytosis compared with controls (121+/-58 pg/mL). Analyzing the different groups, patients with essential thrombocythemia had the lowest TPO levels (120+/-28 pg/mL) and patients with solid tumors the highest levels (162+/-59 pg/mL). Patients with clonal thrombocytosis were older, had higher platelet counts, mean platelet volume and hemoglobin, and lower erythrocyte sedimentation rate than patients with reactive thrombocytosis. INTERPRETATION AND CONCLUSIONS: Minor differences were observed in TPO levels between patients with primary and secondary thrombocytoses. Erythrocyte sedimentation rate, but not TPO levels, may be a useful tool for discriminating both types of thrombocytoses.  (+info)

Neutrophil activation and hemostatic changes in healthy donors receiving granulocyte colony-stimulating factor. (8/2217)

Granulocyte colony-stimulating factor (G-CSF) enhances neutrophil functions in vitro and in vivo. It is known that neutrophil-derived products can alter the hemostatic balance. To understand whether polymorphonuclear leukocyte (PMN) activation, measured as PMN degranulation and phenotypical change, may be associated to hemostatic alterations in vivo, we have studied the effect of recombinant human G-CSF (rHuG-CSF) administration on leukocyte parameters and hemostatic variables in healthy donors of hematopoietic progenitor cells (HPCs). Twenty-six consecutive healthy donors receiving 10 micrograms/kg/d rHuG-CSF subcutaneously for 5 to 7 days to mobilize HPCs for allogeneic transplants were included in the study. All of them responded to rHuG-CSF with a significant white blood cell count increase. Blood samples were drawn before therapy on days 2 and 5 and 1 week after stopping rHuG-CSF treatment. The following parameters were evaluated: (1) PMN activation parameters, ie, surface CD11b/CD18 antigen expression, plasma elastase antigen levels and cellular elastase activity; (2) plasma markers of endothelium activation, ie, thrombomodulin (TM) and von Willebrand factor (vWF) antigens; (3) plasma markers of blood coagulation activation, ie, F1+2, TAT complex, D-dimer; and (4) mononuclear cell (MNC) procoagulant activity (PCA) expression. The results show that, after starting rHuG-CSF, an in vivo PMN activation occurred, as demonstrated by the significant increment of surface CD11b/CD18 and plasma elastase antigen levels. Moreover, PMN cellular elastase activity, which was significantly increased at 1 day of treatment, returned to baseline at day 5 to 6, in correspondence with the elastase antigen peak in the circulation. This change was accompanied by a parallel significant increase in plasma levels of the two endothelial and the three coagulation markers. The PCA generated in vitro by unstimulated MNC isolated from rHuG-CSF-treated subjects was not different from that of control cells from untreated subjects. However, endotoxin-stimulated MNC isolated from on-treatment individuals produced significantly more PCA compared with both baseline and control samples. All of the parameters were decreased or normal 1 week after stopping treatment. These data show that rHuG-CSF induces PMN activation and transiently affects some hemostatic variables in healthy HPC donor subjects. The clinical significance of these findings remains to be established.  (+info)

In patients with thrombocytopenia, it can be difficult to predict a patients bleeding risk based on platelet count alone. Platelet reactivity may provide additional information; however, current clinical assays cannot reliably assess platelet function in the setting of thrombocytopenia. New methods to study platelet reactivity in thrombocytopenic samples are needed. In this study, we sought to develop a laboratory model of thrombocytopenia using blood from healthy subjects that preserves the whole blood environment and reproducibly produces samples with a specific platelet count and hematocrit. We compared the activation state of unstimulated and agonist-stimulated platelets in thrombocytopenic samples derived from this method with normocytic controls. Whole blood was diluted with autologous red blood cell concentrate and platelet-poor plasma, which were obtained via centrifugation, in specific ratios to attain a final sample with a predetermined platelet count and hematocrit.

Platelets are an important blood component that helps in controlling bleeding. The most abundant particle in our blood is the platelet that causes the blood to clot whenever theres a cut or injury, thereby stopping the bleeding in minutes. Now, there are tens and thousands of platelets in normal which help in this process. But in cases of certain diseases and illness like dengue etc the platelets gets destroyed by the infective germ, making the body prone to bleeding. Such a low count of platelet can cause serious brain damage and other organ damage. Apart from a blood transfusion, the most trusted way to increase your platelet count is by eating low platelets treatment food. Foods to increase platelet count are often used as basic preventive care and home remedy for diseases like dengue.

Immune thrombocytopenia (ITP) is a heterogeneous autoimmune disease characterized by the presence of platelet autoantibodies, low platelet counts and an increased risk of bleeding. TPO receptor agonists which stimulate platelet production have been shown to be remarkably effective in ITP. Their use as a short-term means of elevating platelet counts in preparation for surgical procedures has not yet been adequately evaluated.. Many patients with moderate to severe ITP (platelet count less than 50 x 10exp9/L) have stable platelet counts and do not bleed; however, when surgeries or invasive procedures become necessary, additional treatment is often required to increase the platelet count to achieve adequate hemostasis. Although specific guidelines for surgical platelet count thresholds in ITP are lacking, platelet transfusion guidelines recommend a platelet count of 50 - 100 x10exp9/L for the vast majority of surgical procedure; 50x10exp9/L is a typical threshold for minor surgeries like tooth ...

Rheumatoid Arthritis And Low Blood Platelets Count- thrombocytopenia the term for low blood platelets if you suffer from thrombocytopenia,you lack required platelets in your blood.
Mucosal healing (MH) has been indicated as the therapeutic goal for ulcerative colitis (UC). Platelet count is known as an inflammation evaluation. However, the association between platelet count and MH among patients with UC is still scarce. We therefore assessed this issue among Japanese patients with UC. The study subjects consisted of 345 Japanese patients with UC. Platelet count was divided into quartiles on the basis of the distribution of all study subjects (low, moderate, high, and very high). Several endoscope specialists were responsible for evaluating MH and partial MH, which was defined as a Mayo endoscopic subscore of 0 and 0-1, respectively. Estimations of crude odds ratios (ORs) and their 95% confidence intervals (CIs) for partial MH and MH in relation to platelet count were performed using logistic regression analysis. Age, sex, CRP, steroid use, and anti-Tumor necrosis factor α (TNFα) preparation were selected a priori as potential confounding factors. The percentage of partial MH and

TPO-RAs could be theoretically useful in IT patients in two clinical contexts. Short-term treatment courses could be used to transiently increase platelet count in preparation for elective surgery or invasive procedures. Moreover, patients at high risk of spontaneous bleeding may benefit from long-term administration. Results obtained so far are promising in that they indicate that TPO-RAs may be effective, but experience in this field is still limited.. In a small clinical trial, 12 consecutive patients with MYH9-RD and platelet counts lower than 50 × 109/L were treated with eltrombopag for 3-6 weeks. Eleven patients responded, and 8 of them achieved major responses (platelet count higher than 100 × 109/L or three times the baseline value). Treatment was well tolerated and bleeding diathesis disappeared in 8 of 10 patients with spontaneous bleeding at baseline [10]. Based on these results, one patient with MYH9-RD and ,20 × 109 platelets/L received eltrombopag for preparation to a major ...
The first person is an elderly woman, in the infusion center to get platelets. Normal platelet count is 150-400 and you can walk around with a platelet count of 80 and in general be ok. Her platelet count was six. At 15 they give you a platelet transfusion. So she is basically a train wreck waiting to happen. Brain bleeds, internal organ leakage - nasty stuff. You really need platelets to do what youd like to do - like walk around without having your organs bleed internally. So youd expect this woman to be super stressed, or terrified or something. But no. She just walks in (carefully, because if you bruise yourself when your platelet count is six, you are some kind of fucked.) Sits in the chair, gets hooked up, calm as can be and sucks up the life giving platelets. And oh yeah, she has an incurable blood disease and will be dead in six months. And her daughter is with her, bemoaning how the universe can allow someone to hit and run her car while shes transporting her dying mother to the ...
we got quite a scare after bro is diagnosed with dengue. it all started with fever, loss of appetite and pananamlay for 2 days. of course, we thought its just the usual fever, flu that can be cured with a dose of tempra. his fever went on-off for 2 days and mama, the paranoid that she is (well, good for all of us na rin) urged him to see the doc. the first time, it was holiday so we just went to the ER ang got some stronger meds. the attending physician wanted to admit him but mama wanted him to be checked by our doctor personally. so off we went home. the next day, ayun... after series of tests, it was confirmed. DENGUE. normal platelet count should be above 150k but his is 104K. blood transfusion will be administered when it reaches 20K. thats the SOP, as i know. i dont know much about dengue and anything that keeps a person hospitalized is enough for me to be worried. who wouldnt la?! i read related stuff in the internet, even suggested this one drink to help increase platelet count... ...

Bloodwork and Platelet count - Im back again, I had breast cancer in late 2017 and had a lumpectomy.  I just got my blood tested as my hair is falling out for some reason . Im not doing chemo or radiation or being treated for cancer at this time.  My bloodwork is back I know the results and I do have a doctor apt wednesday. I got my results from dyna care. My platelet count is high as well at my white blood cells and my WBC is high too. Im not sick at all . But Im so tired and not a normal tired . I have been tired for about three months anyway.  I had a mammogram in Aug and it came back ok. Im worried the cancer has spread into my blood now.  Has anyone else had this issue and it turned out to be cancer . I just dont have a good feeling inside I need some advice or suggestions  Thankyou  - Share your thoughts!
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).

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 ...

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

AU - Luviah, Evah. AU - Adiwinata, Jeanne. PY - 2014/1/1. Y1 - 2014/1/1. N2 - Platelet concentrate (PC) has been used as substitute to the use of fetal bovine serum (FBS) in cell culture media. 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 ...
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

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 ...

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 ...
