Effect of obesity on red cell mass results. (1/454)

Measurement of red cell mass with isotope dilution remains an important diagnostic test in the evaluation of patients with suspected polycythemia vera (PCV). Results and reference ranges are typically expressed in units normalized for body weight (mL/kg). Obesity is common in polycythemic patients, and it is important to know how the various published normative ranges compare across a wide range of body weights. METHODS: We retrospectively reviewed 51 consecutive patients referred for red cell mass determination with 51Cr red blood cell dilution. Results were expressed in milliliters per kilogram (mL/kg) by using the actual patient weight and after adiposity adjustments using ideal body weight, body mass index (BMI) and combinations of height-weight, including body surface area. Results were classified as normal, elevated or PCV. RESULTS: There was a high prevalence of obesity in our population (28/51 [55%] with BMI > 27 kg/m2, BMI range 16.0-54.8 kg/m2). The method used to compensate for obesity had a dramatic effect on the derived red cell mass, the fraction of patients with elevated measurements and the fraction of patients meeting criteria for PCV. Concordance for categorization as normal, elevated or PCV by all methods was only 47.1%. CONCLUSION: Obesity is a common confounding factor in the interpretation of red cell mass measurements. Currently published reference ranges generate inconsistent results when extrapolated to obese patients. Further normative data on obese subjects are needed to determine which method (if any) is optimal.  (+info)

Posttranslational processing of the thrombopoietin receptor is impaired in polycythemia vera. (2/454)

Recently, we demonstrated a marked reduction in the expression of the thrombopoietin receptor, Mpl, in polycythemia vera (PV) platelets and megakaryocytes using an antiserum against the Mpl extracellular domain. To further examine this abnormality, we raised an antibody to the Mpl C-terminus. Immunologic analysis of PV platelets with this antiserum confirmed the reduction in Mpl expression. However, the C-terminal antiserum detected 2 forms of Mpl in PV platelets in contrast to normal platelets, in which a single form of Mpl was detected by both the extracellular domain and C-terminal antisera. Two-dimensional gel electrophoresis studies with isoelectric focusing in the first dimension identified normal platelet Mpl as an 85 to 92 kD protein with an isoelectric point (pI) of 5.5. PV platelets contained an additional 80 to 82 kD Mpl Mpl isoform with a pI of 6.5. Analysis of Mpl expressed by the human megakaryocytic cell line, Dami, showed 2 isoforms similar to those found in PV platelets suggesting a precursor-product relationship. Digestion of Dami cell and normal platelet lysates with neuraminidase converted the more acidic Mpl isoform to the more basic one, indicating that the 2 isoforms differed with respect to posttranslational glycosylation. Furthermore, in contrast to normal platelet Mpl, PV platelet Mpl was susceptible to endoglycosidase H digestion, indicating defective Mpl processing by PV megakaryocytes. The glycosylation defect was specific for Mpl, as 2 other platelet membrane glycoproteins, glycoprotein IIb and multimerin, were processed normally. Importantly, the extent of the PV platelet Mpl glycosylation defect correlated with disease duration and extramedullary hematopoiesis.  (+info)

Nonrandom chromosomal abnormalities in hematologic disorders of man. (3/454)

A nonrandom pattern of chromosomal abnormalities occurs in bone marrow cells obtained from patients with hematologic disorders who have an abnormal karyotype involving a C group chromosome. An additional number 8 chromosome is the most common abnormality, found in more than one-half of the patients studies. An additional number 9 chromosome and the loss of all or part of a number 7 are abnormalities that occur more often than might be expected by chance. It is proposed that specific human chromosomal abnormalities may be related to different specific etiologic agents.  (+info)

Electron microscopic x-ray microanalysis of normal and leukemic human lymphocytes. (4/454)

A comparative study of the elemental content of normal and leukemic cells was undertaken on a few subjects, using electron microscopic x-ray microanalysis. Phosphorus, sulfur, chlorine, calcium, copper, and zinc were detected in intracellular loci. The concentration of some of the above elements appeared to be disease related. In leukemic lymphocytes, the nuclear zinc was significantly lower than that recorded in normal lymphocytes, while the phosphorus was only moderately decreased. This suggests a faulty zinc uptake or binding in leukemic cells. The possible consequences of intracellular zinc deficiency are discussed.  (+info)

Cloning of PRV-1, a novel member of the uPAR receptor superfamily, which is overexpressed in polycythemia rubra vera. (5/454)

Polycythemia vera (PV) is a clonal stem cell disorder characterized by hyperproliferation of the erythroid, myeloid, and megakaryocytic lineages. Although it has been shown that progenitor cells of patients with PV are hypersensitive to several growth factors, the molecular pathogenesis of this disease remains unknown. To investigate the molecular defects underlying PV, we used subtractive hybridization to isolate complementary DNAs (cDNAs) differentially expressed in patients with PV versus normal controls. We isolated a novel gene, subsequently named PRV-1, which is highly expressed in granulocytes from patients with PV (n = 19), but not detectable in normal control granulocytes (n = 21). Moreover, PRV-1 is not expressed in mononuclear cells from patients with chronic myelogenous leukemia (n = 4) or acute myelogenous leukemia (n = 5) or in granulocytes from patients with essential thrombocythemia (n = 4) or secondary erythrocytosis (n = 4). Northern blot analysis showed that PRV-1 is highly expressed in normal human bone marrow and to a much lesser degree in fetal liver. It is not expressed in a variety of other tissues tested. Although PRV-1 is not expressed in resting granulocytes from normal controls, stimulation of these cells with granulocyte colony-stimulating factor induces PRV-1 expression. The PRV-1 cDNA encodes an open reading frame of 437 amino acids, which contains a signal peptide at the N-terminus and a hydrophobic segment at the C-terminus. In addition, PRV-1 contains 2 cysteine-rich domains homologous to those found in the uPAR/Ly6/CD59/snake toxin-receptor superfamily. We therefore propose that PRV-1 represents a novel hematopoietic receptor. (Blood. 2000;95:2569-2576)  (+info)

Acute myelogenous leukaemia and myelomonocytic blast crisis following polycythemia vera in HIV positive patients: report of cases and review of the literature. (6/454)

BACKGROUND: Acute myelogenous leukaemia (AML) and myeloproliferative diseases are rare in HIV-infected individuals and optimal treatment has not been defined. PATIENTS AND METHODS: We report on the cases of two HIV-infected men, one with AML and one with myeloid blast crisis after polycythaemia vera (PV). A comprehensive review of the available literature will be presented. RESULTS: Patient 1, a 57-year-old bisexual man known to be HIV seropositive for more than four years (CDC-category A1), presented with a pulmonary infiltrate. On admission WBC showed leukocytes 5.6 x 10(9)/l and the differential revealed 80% blasts. A diagnosis of AML FAB M0 was made. Pneumonia resolved under antibiotic treatment and the patient received induction chemotherapy. However, he once more developed multiple pulmonary infiltrates and died of respiratory failure despite broad spectrum antibiotic and antimycotic therapy. Autopsy revealed pulmonary aspergillosis. Patient 2 was a 63-year old HIV-positive hemophiliac (CDC A3) with a 10-year history of PV. On admission his white cell count showed leukocytes 256.6 x 10(9)/l with 82% blasts. Cytochemistry revealed myelomonocytic differentiation. The patient died of tumor lysis syndrome with renal and cardio-pulmonary failure two days later. CONCLUSIONS: This is the first report of an HIV-infected individual with AML M0. The literature describes the cases of 39 HIV+ patients with AML and only one further case with PV. The association of both, myeloproliferative disease and AML with HIV infection is coincidental. However, the proportion of FAB type M4/5 appears to be higher than in the general population. Despite a high risk of treatment associated mortality durable remissions can be achieved in a small proportion of HIV-infected patients with AML.  (+info)

Tumor-like splenic extramedullary hematopoiesis in a patient with myelofibrosis. (7/454)

A 61-year-old woman, who was diagnosed in 1982 as having polycythemia vera, was admitted to our hospital in July 1998 because of a splenic tumor in an enlarged spleen due to myelofibrosis. As it was difficult to identify the etiology of the splenic tumor, partial splenectomy was carried out. The resected tumor proved to be an extremely proliferative lesion as the result of extramedullary hematopoiesis. Since it is difficult to diagnose the etiology of splenic tumor, the collection and analysis of reports of relevant cases may well facilitate diagnosis.  (+info)

Towards a molecular understanding of polycythemia rubra vera. (8/454)

Polycythemia rubra vera (PV) is one of four diseases collectively called the myeloproliferative disorders (MPDs). Each disorder leads to an increased production of one or several hematopoietic cell lineages. MPDs arise from acquired mutations in a pluripotent hematopoietic stem cell. However, the molecular mechanisms leading to the development of these diseases are poorly understood. This review will summarize and evaluate recent advances in our understanding of one particular MPD, PV.  (+info)

The Janus kinase 2 gene (JAK2) codes for a tyrosine kinase (JAK2) that is associated with the cytoplasmic portion of a variety of transmembrane cytokine and growth factor receptors important for signal transduction in hematopoietic cells. Signaling via JAK2 activation causes phosphorylation of downstream signal transducers and activators of transcription (STAT) proteins (eg, STAT5) ultimately leading to cell growth and differentiation. The JAK2 V617F is located in exon 14 and present in 50% to 60% of primary myelofibrosis and essential thrombocythemia, and 95% to 98% of polycythemia vera (PV). In the rest of the polycythemia vera cases, over 50 different mutations have been reported within exons 12 through 15 of JAK2 and essentially all of the non-V617F JAK2 mutations have been identified in polycythemia vera. These mutations include point mutations and small insertions or deletions. Several of the exon 12 mutations have been shown to have biologic effects similar to those caused by the V617F ...

TY - JOUR. T1 - Current management of polycythemia vera. AU - Tefferi, Ayalew. PY - 2002. Y1 - 2002. N2 - Over a century has elapsed since the first description of polycythemia vera (PV), and current treatment recommendations are primarily based on the results of clinical trials that were performed in the late 1960s and early 1970s. Continued identification and appropriate utilization of PV-specific biologic parameters may allow substantial modification of early diagnostic criteria. New cytoreductive treatment agents are increasingly being used without any evidence of superiority over conventional therapy. The role of aspirin is being readdressed by an ongoing controlled study. Transformation of PV into either myelofibrosis with myeloid metaplasia or acute leukemia remains a major complication that may not be influenced by current therapy..

Primary polycythemias are due to factors intrinsic to red cell precursors. Polycythemia vera (PCV), polycythemia rubra vera (PRV), or erythremia, occurs when excess red blood cells are produced as a result of an abnormality of the bone marrow.[3] Often, excess white blood cells and platelets are also produced. PCV is classified as a myeloproliferative disease. Symptoms include headaches and vertigo, and signs on physical examination include an abnormally enlarged spleen and/or liver. In some cases, affected individuals may have associated conditions including high blood pressure or formation of blood clots. Transformation to acute leukemia is rare. Phlebotomy is the mainstay of treatment. A hallmark of polycythemia is an elevated hematocrit, with Hct , 55% seen in 83% of cases.[4] A somatic (non-hereditary) mutation (V617F) in the JAK2 gene is found in 95% of cases, though also present in other myeloproliferative disorders.[5]. Primary familial polycythemia, also known as primary familial and ...

Inhibition of histone deacetylases may be an important target in patients with myeloproliferative neoplasms. This investigator-initiated, non-randomized, open-label phase II multi-centre study included 63 patients (19 essential thrombocythaemia, 44 polycythaemia vera) from 15 centres. The primary objective was to evaluate if vorinostat was followed by a decline in clonal myeloproliferation as defined by European Leukaemia Net. Thirty patients (48%) completed the intervention period (24 weeks of therapy). An intention-to-treat response rate of 35% was identified. Pruritus was resolved [19% to 0% (P=0.06)] and the prevalence of splenomegaly was lowered from 50% to 27% (P=0.03). Sixty-five per cent of the patients experienced a decrease in JAK2 V617F allele burden (P=0.006). Thirty-three patients (52% of patients) discontinued study drug before end of intervention due to adverse events (28 patients) or lack of response (5 patients). In conclusion, vorinostat showed effectiveness by normalizing ...
Abstract. Most patients with polycythemia vera (PV) and half of essential thrombocythemia (ET) possess an activating JAK2V617F mutation. The objective of this study was to better define the effect of JAK2V617F mutant allele burden on clinical phenotypes in Chinese patients, especially thrombosis. By real-time polymerase chain reaction (RT-PCR), the JAK2V617F mutation burden was detected in 170 JAK2V617F-positive patients, including 54 PV and 116 ET. The results showed that JAK2V617F allele burden was higher in PV than in ET (P, 0.001). Higher percentage of patients had JAK2V617F allele burden over 20% in PV than in ET (68.5% VS 26.7%) (P, 0.001). In PV patients, higher JAK2V617F allele burden was observed in female (P, 0.05) and leukocytosis patients (WBC above 10×109/L) (P, 0.001). Meanwhile, ET patients showed increased JAK2V617F allele burden in the group with higher hemoglobin (HGB above 150g/L) (P, 0.05), leukocytosis (WBC above 10×109/L) (P, 0.001), splenomegaly (P, 0.05) and thrombosis ...

Lay Summary: Polycythemia vera is a chronic blood cancer that can cause severe complications and early death. Differences in clinical features and outcome have been observed in younger (age ≤ 45) versus older (age ≥ 65) patients with PV. We seek to understand the basis for these differences, and propose a series of genetic and functional studies to address these issues. The long term goal of this work is to leverage the findings from this study to improve longevity for patients with PV.. Full Summary: Polycythemia vera (PV) is a chronic myeloproliferative neoplasm (MPN) that is defined by erythrocytosis and associated with thrombotic complications and a propensity for transformation to myelofibrosis (MF) or secondary acute myeloid leukemia (sAML). Overall survival for patients with PV is substantially impaired compared to age-matched controls. Recent studies have identified age-related differences in disease characteristics and clinical outcome in PV, including distinct JAK2 V617F allele ...
CancerConnect News: A new drug called Jakafi® (ruxolitinib) appears to help patients with polycythemia vera (PV) maintain hematocrit control more effectively than best available therapy. These findings were presented at the 56th American Hematology Society Annual Meeting and Exposition, December 6-9, 2014, in San Francisco, California.[1]. Polycythemia vera is a slow-growing type of blood cancer that belongs to a group of blood disorders called myeloproliferative neoplasms (MPN). In these disorders, the bone marrow cells that produce blood cells develop and function abnormally. In PV the bone marrow makes too many blood cells, particularly red blood cells. These excess cells thicken the blood and can cause complications, such as a risk of blood clots or bleeding. Without treatment, PV can be life threatening and can eventually progress to more serious blood cancers, such as myelofibrosis or acute leukemia. Effective treatment, however, can significantly decrease risks and complications.. The ...

Polycythemia vera is one type of myeloproliferative disorder (MPD). Bone marrow contains stem cells that have the ability to mature into adult blood cells that enter the circulation, including red blood cells, white blood cells, and platelets. These stem cells are referred to as pluripotent hematopoeitic precursor cells, or PHPC, due to their versatility. Each PHPC can reproduce itself (clone), in addition to producing daughter cells, called blasts.. In MPD, one abnormal PHPC clone has an ability to overgrow and self-renew more effectively then normal PHPC clones. In polycythemia vera, there may be an increase in just the red blood cells, both the red and white blood cells, or in the red and white blood cells and platelets.. The abnormal PHPC clone is the result of mutations to genes in these cells. These mutations are not inherited, but happen during a persons lifetime. Why this happens to a given individual is unknown in most cases.. ...
Basel, June 13, 2015 - Novartis today announced long-term safety and efficacy results from the pivotal Phase III RESPONSE study evaluating Jakavi® (ruxolitinib) for the treatment of patients with polycythemia vera (PV) who are resistant to or intolerant of hydroxyurea. A preplanned analysis of the study at 18 months demonstrated that 80% of patients with inadequately controlled PV treated with Jakavi experienced a durable response of sustaining hematocrit less than 45% without the use of phlebotomy and reducing spleen size, two key measures of disease control, for at least one year[1]. Findings were presented at the 20th Congress of the European Hematology Association (EHA) in Vienna, Austria.. Polycythemia vera can lead to serious complications if inadequately controlled, and these data demonstrate the ability of Jakavi to provide a durable and comprehensive clinical benefit in this patient population, said lead study investigator Jean-Jacques Kiladjian, MD, PhD, Hôpital Saint-Louis et ...
Polycythemia vera is a serious, but very rare blood disorder in children. With polycythemia vera, the bone marrow makes too many red blood cells. The extra cells make the blood too thick. This may lead to blood clots. The clots can decrease the blood supply to organs, tissues, and cells.
Our interest was aroused in the significance of the association of duodenal ulcer and polycythemia vera as a result of observation of a patient who had both diseases. A review of the literature revealed interesting speculations in regard to the association of these conditions because of recent demonstrations of the relation of gastric secretion and hematopoietic function. It seemed reasonable that with the large amount of material available at this clinic some conclusions might be drawn as to the incidence of association of these diseases.. In the available medical textbooks, the gastrointestinal symptoms associated with polycythemia vera are minimized. Osler1 ...

The molecular pathogenesis of these disorders is unknown, but tyrosine kinases have been implicated in several related disorders. We investigated the role of the cytoplasmic tyrosine kinase JAK2 in patients with a myeloproliferative disorder.We obtained DNA samples from patients with polycythaemia vera, essential thrombocythaemia, or idiopathic myelofibrosis. The coding exons of JAK2 were bidirectionally sequenced from peripheral-blood granulocytes, T cells, or both. Allele-specific PCR, molecular cytogenetic studies, microsatellite PCR, Affymetrix single nucleotide polymorphism array analyses, and colony assays were undertaken on subgroups of patients.A single point mutation (Val617Phe) was identified in JAK2 in 71 (97%) of 73 patients with polycythaemia vera, 29 (57%) of 51 with essential
The most common are polycythemia vera, essential thrombocythemia, primary myelofibrosis, and chronic myelogenous leukemia (CML). The signs and symptoms of PV include: Polycythemia: Types list. Though there is no known cure for the disorder, there are many different types of polycythemia vera treatment to help lower a patients blood cell counts, decrease the viscosity of the blood, and prevent bleeding or clotting. When signs and symptoms are present, theyre the result of the thick blood that occurs with PV. It is most commonly found by doctors in men over 60 years of age. Signs may include: An increase in red blood cells, platelets and white bloods cells A high hematocrit (the proportion of red blood cells in the blood) An increase in hemoglobin concentration (a protein found in red blood cells) Low levels of erythropoietin (a hormone that controls red blood cell production) Additional tests may include: Secondary polycythemia - also called reactive polycythemia - is characterized by excessive ...

The word polycythemia simply means many cells in the blood. There are two forms of this disease: polycythemia vera and secondary polycythemia. Polycythemia vera (also called primary polycythemia) is a rare growth disorder of the bone marrow, occurring when the marrow is overactive and produces more blood cells than the…
We studied the relationship between JAK2 (V617F) mutant allele burden and clinical phenotype, disease progression and survival in patients with polycythemia vera (PV). The percentage of granulocyte mutant alleles was evaluated using a quantitative real-time polymerase chain reaction-based allelic discrimination assay. Of the 338 patients enrolled in this prospective study, 320 (94.7%) carried the JAK2 (V617F) mutation. Direct relationships were found between mutant allele burden and hemoglobin concentration (P=0.001), white blood cell count (P=0.001), spleen size (P=0.001) and age-adjusted bone marrow cellularity (P=0.002), while an inverse relationship was found with platelet count (P,0.001). During the study period, eight patients progressed to post-PV myelofibrosis (MF) (all carrying ,50% mutant alleles), while 10 patients developed acute myeloid leukemia (AML). The mutant allele burden was significantly related to the risk of developing myelofibrosis (P=0.029) and retained its significant ...
SUMMARY. The serum unsaturated vitamin B12-binding capacity (UBBC) was found to be of value in distinguishing polycythemia vera from other conditions that are accompanied by an elevated hematocrit or an absolute erythrocytosis and as an indicator of disease activity in polycythemia vera. The serum vitamin B12 level was of lesser value. Increased levels of serum vitamin B12 were observed in 36% and increased levels of UBBC in 70% of patients with untreated polycythemia vera and related myeloproliferative disorders, as contrasted with normal serum vitamin B12 levels in 98% and normal UBBC in 87% of cases of spurious (relative) polycythemia and isolated erythrocytosis (secondary and unclassified polycythemia). Serum vitamin B12 and UBBC levels in polycythemia vera treated only with phlebotomy did not differ from values in untreated cases, whereas patients whose erythroid activity had been controlled by myelosuppressive therapy had levels comparable to those in normal subjects. UBBC values were ...

Research in the Jerry Spivak Lab focuses on chronic myeloproliferative disorders, particularly their molecular mechanisms and methods for distinguishing them diagnostically and interventionally. By analyzing gene expression in polycythemia vera stem cells, we have learned that patients with polycythemia vera can be differentiated from those with erythrocytosis and can be diagnosed as having either aggressive or slow-growing disease. We are also studying the roles played by specific molecular markers in the pathogenesis and diagnosis of polycythemia vera.. Research Areas: stem cells, pathogenesis, polycythemia vera, myeloproliferative disorders ...
The quality of life (QoL) at the time of diagnosis of myeloproliferative neoplasm (MPN) has, to date, not been studied. One hundred and seventy-nine patients with MPN: 80 with essential thrombocythemia (ET), 73 with polycythemia vera (PV), 22 with primary myelofibrosis (PMF) and four with MPN undifferentiated, were included in this study. European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQC30) and the MPN-Symptom Assessment Form (MPN-SAF) were used to evaluate QoL. Fatigue was the most reported symptom in these patients. Patients with PV reported significantly higher mean scores for inactivity, dizziness, cough, itching, depression and lower total QoL compared to patients with ET. Patients with PV had significantly more headache and itching compared to patients with PMF. When the newly diagnosed patients with MPN were compared with a cohort of patients with MPN with mean disease duration of 7.8 years, the differences were most striking for ...

We report the final two-year end-of-study results from the first clinical trial investigating combination treatment with ruxolitinib and low-dose pegylated interferon-α2 (PEG-IFNα2). The study included 32 patients with polycythemia vera (PV) and 18 with primary- or secondary myelofibrosis (MF); 46 patients were previously intolerant or refractory to PEG-IFNα2. The primary outcome was efficacy, based on hematological parameters, quality of life measurements, and JAK2 V617F allele burden. We used the 2013 ELN and IWG-MRT response criteria, including response in symptoms, splenomegaly, peripheral blood counts, and bone marrow. Of 32 patients with PV, 10 (31%) achieved remission; 3 (9%) achieved complete remission. Of 18 patients with MF, 8 (44%) achieved remission; 5 (28%) achieved complete remission. The cumulative incidence of peripheral blood count remission was 0.85 and 0.75 for patients with PV and MF, respectively. MPN-SAF total symptom score decreased from 22 (95%CI, 16-29) at baseline to ...
Polycythemia vera (PV) and essential thrombocythemia (ET) are myeloproliferative neoplasms with variable risk of evolution into post-PV and post-ET myelofibrosis, from now on referred to as secondary myelofibrosis (SMF). No specific tools have been defined for risk stratification in SMF. To develop a prognostic model for predicting survival, we studied 685 JAK2, CALR, and MPL annotated patients with SMF. Median survival of the whole cohort was 9.3 years (95% CI: 8-not reached-NR-). Through penalized Cox regressions we identified negative predictors of survival and according to beta risk coefficients we assigned 2 points to hemoglobin level |11 g/dl, to circulating blasts ⩽3%, and to CALR-unmutated genotype, 1 point to platelet count |150 × 109/l and to constitutional symptoms, and 0.15 points to any year of age. Myelofibrosis Secondary to PV and ET-Prognostic Model (MYSEC-PM) allocated SMF patients into four risk categories with different survival (P|0.0001): low (median survival NR; 133 patients),

Advanced polycythemia vera (PV) may occur in a subset of patients with elevated hematocrit levels plus elevated white blood cell counts or disease related symptoms, despite treatment with HU at the maximum tolerated dose and phlebotomy.
Polycythemia vera is a rare blood disorder that occurs more often in men than in women. Its rarely seen in anyone under age 40. PV is usually associated with a gene mutation called JAK2 V617F. The JAK2 gene handles production of a protein that helps make blood cells. About 95 percent of people with PV have this mutation.. Mutations are changes or damage in the bodys DNA. DNA is responsible for all of your physical characteristics, from eye color to fingerprints. The mutation that causes PV can be acquired, which means something has damaged the DNA (instead of being born with it) and passed on within families. More research needs to be done to understand what causes the genetic mutation behind PV.. If you have PV, the genetic mutation causes your bone marrow to produce too many red blood cells. The production of red blood cells within your bone marrow is normally tightly regulated. Having too many red blood cells in your bloodstream can cause the blood to clot and lead to dangerous ...

If you suffer from polycythemia vera, which is a serious disease that can result in death, you may be unable to work. In those situations, you may qualify for Social Security disability benefits. The Social Security Administration (SSA) oversees the Social Security Disability Insurance (SSDI) program, which provides monthly benefits to disabled workers. In order to be eligible for SSDI, you have to have worked enough to pay in sufficient taxes to the SSA and to have earned an adequate amount of credits. The monthly benefits paid through SSDI can help relieve the financial stress of being unable to work. In some instances, you may have dependents who are also eligible to receive benefits if you approved. Polycythemia vera is a disorder that impacts the bodys bone marrow. If you suffer from this condition, your body creates too many red blood cells, platelets, and white blood cells. The over-production of red blood cells can cause a variety of symptoms, including some which are life-threatening. ...
In polycythemia vera (PV) and essential thrombocythemia (ET) the discovery of the presence of JAK2V617F mutations indicates that tyrosine kinase activation is a common pathogenetic mechanism in Ph- MPD.1 The main therapeutic goal is to diminish the risk of clinical complications without increasing the risk of the development of myelofibrosis or acute leukemia. Hydroxyurea (HU) is widely used as a first line myelosuppressive therapy for patients with PV and ET.2,3 The control of the thrombocytosis is usually rapid and effective with initial treatment with HU,2 but the effect upon the JAK2V617F allele burden has not been studied. The JAK2V617F expression has been shown to decrease with IFN therapy and in some patients the mutated clone even seems to be eradicated.4 The aim of this study was to investigate the JAK2V617F response of HU treatment in newly diagnosed patients with PV or ET. Nine patients with PV and 9 with ET positive for JAK2V617F with high risk MPD3 and need for myelosuppressive ...
The Philadelphia chromosome negative myeloproliferative neoplasms (MPN) are a group of clonal hematological malignancies that are characterized by a chronic course which can be punctuated by a number of disease related events including thrombosis, hemorrhage, pruritis and leukemic transformation. These disorders include Polycythemia Vera (PV), Essential Thrombocythemia (ET) and Primary Myelofibrosis (PM). Recently an acquired somatic mutation in the intracellular kinase, JAK2 (JAK2V617F) has been observed in 95% of patients with PV, 50% of patients with ET and 50% of patients with primary myelofibrosis. At present the chemotherapeutic agent hydroxyurea is the standard of care for high risk patients with PV. Concern exists about prolonged use of this drug leading to leukemia and the inability of hydroxyurea to eliminate the malignant clone.. Interferon (rIFN -2b), is a drug that appears to be non-leukemogenic, and may have a preferential activity on the malignant clone in PV, as suggested by ...
Extramedullary hematopoiesis (EMH) can occur in many disorders including thalassemias, polycythemia rubra vera, myelofibrosis, hemolytic anemia and other hemoglobinopathies. Spinal cord compression due to EMH in thalassemia was first reported by Gatto in 1954.2 It usually has a predilection for the lower thoracic spine where the limited mobility and narrow spinal canal predisposes itself to spinal cord compression.3,6 Most cases present with paraparesis, sensory impairment and occasionally sphincter disturbances. Complete paraplegia has been reported very rarely in thalassemia and occurs more frequently in polycythemia rubra vera and sickle cell anemia.1 The diagnostic procedure of choice is magnetic resonance imaging (MRI) which characteristerically shows an isointense mass with a high spinal intensity rim on T1-weighted images and a hyperintense mass on T2-weighted images.4 The diagnosis is based on strong clinical suspicion in the presence of diffuse bone marrow hyperplasia along with ...

In this study we investigate the promoter methylation of these genes in the pathogenesis of MPNs and secondary erythrocytosis/thrombocythemia ...
A number of widely held misconceptions result in inappropriate venesection. First, that it is performed to prevent the risk of stroke, therefore secondly, that it should be done routinely to keep the haematocrit , 65% regardless of symptoms, and thirdly that volume replacement is not required.. The idea that hyperviscosity is a risk factor for cerebral arterial thrombosis in adults with cyanotic heart disease has arisen from studies in other patient groups. This, along with the observation that symptoms of reduced cerebral blood flow secondary to hyperviscosity are transiently relieved by venesection, has led to the widespread belief that haematocrit levels in patients with cyanotic heart disease should not be allowed to rise too high.. The risk of vascular occlusion in patients with primary polycythaemia rubra vera relates both to degree of erythrocytosis and to thrombocytosis, and treatment guidelines in this disease recommend venesection to maintain a haematocrit ⩽ 45.2 6Haematologists ...
The PRV-1 gene has been proposed as a marker of polycythaemia vera (PV). PRV-1 and NB1 are alleles of the polymorphic gene CD177, which belongs to the Ly-6/uPAR superfamily, and their coding regions differ at only four nucleotides. We studied neutrophil CD177 mRNA levels in normal subjects and in 235 patients with Ph-negative chronic myeloproliferative disorders (CMD), including PV, essential thrombocythaemia and myelofibrosis with myeloid metaplasia. Additional disease states were investigated for comparison. Highly variable neutrophil CD177 mRNA levels were observed in normal individuals. Neutrophils isolated from the bone marrow, or from peripheral blood following granulocyte colony-stimulating factor administration showed markedly higher CD177 expression than circulating granulocytes on steady state. Increased neutrophil CD177 mRNA levels were detected in all CMD. Elevated values were also found in reactive conditions and in disorders such as chronic myeloid leukaemia and myelodysplastic ...

An erythrocytosis arises when the red cell mass is increased. This can be due to a primary intrinsic defect in the erythroid progenitor cells or secondary to erythropoietin production from some source. Primary and secondary causes can be congenital or acquired. Rare, primary congenital defects are due to mutations leading to truncation of the erythropoietin receptor. The main acquired, primary erythrocytosis is polycythaemia vera. Among the congenital secondary causes, a number of defects in the genes in the oxygen-sensing pathway have recently been described, which lead to a secondary erythrocytosis. An extensive list of acquired secondary causes needs to be considered. A number of patients do not have an identifiable cause of erythrocytosis and are therefore described as having idiopathic erythrocytosis. Investigation should commence with careful clinical evaluation. Determination of the erythropoietin level is then a first step to guide the further direction of investigation. In those with ...
Conclusions:. Essential thrombocythemia, primary myelofibrosis, and polycythemia vera patients exhibited different patterns of cytokine production, as revealed by cytokine network correlations.

An acquired somatic mutation, Jak2V617F, was recently discovered in most patients with polycythemia vera (PV), chronic idiopathic myelofibrosis (CIMF), and essential thrombocythemia (ET). To investigate the role of this mutation in vivo, we transplanted bone marrow (BM) transduced with a retrovirus expressing either Jak2 wild-type (wt) or Jak2V617F into lethally irradiated syngeneic recipient mice. Expression of Jak2V617F, but not Jak2wt, resulted in clinicopathologic features that closely resembled PV in humans. These included striking elevation in hemoglobin level/hematocrit, leukocytosis, megakaryocyte hyperplasia, extramedullary hematopoiesis resulting in splenomegaly, and reticulin fibrosis in the bone marrow. Histopathologic and flow cytometric analyses showed an increase in maturing myeloid lineage progenitors, although megakaryocytes showed decreased polyploidization and staining for acetylcholinesterase. In vitro analysis of primary cells showed constitutive activation of Stat5 and cytokine

The chronic myeloproliferative disorders (CMPD) are a group of clinically related diseases characterized by clonal hematopoiesis with increased proliferation of one or more myeloid cell lineages. The identification of JAK2 mutations (JAK2V617F and JAK2 exon 12) in patients with CMPD is of great significance in the understanding of the molecular mechanisms underlined the pathogenesis of the disease contributing also to clinical management of patients. However, the precise pathogenetic contribution of JAK2 mutation is far from being fully elucidated and it is currently under intense investigation. Testing of JAK2 mutations has made the diagnosis of CMPD more precise than ever before, while genotype-phenotype associations have been identified. Furthermore, the discovery of JAK2 mutations facilitated the development of new targeted therapies and clinical trials are currently ongoing.
PV is a myeloproliferative disorder resulting in an elevated absolute red blood cell mass because of uncontrolled red blood cell production. This is typically associated with an increase in WBC and PLT production. The increase in WBCs and PLTs is secondary to an abnormal clone of hematopoietic stem cells with increased sensitivity to different maturation growth factors. PV is overall rare, occurring in 0.6-1.6 persons per million population. The peak incidence of PV is 50-70 years of age. However, PV may occur in persons of all age groups, including young adults and children, albeit rarely [11].. The increased hematocrit of PV is the main determinant of blood viscosity. As the viscosity increases, cerebral blood flow decreases [6, 7]. PLT marginalization with increased contact to vessel walls occurs, along with local effect of a high hematocrit on vessel walls [6, 7]. This fulfils all three components of Virchows triad [12], and is consistent with the thought that many strokes in polycythemic ...

BACKGROUND: Cancers result from the accumulation of somatic mutations, and their properties are thought to reflect the sum of these mutations. However, little is known about the effect of the order in which mutations are acquired. METHODS: We determined mutation order in patients with myeloproliferative neoplasms by genotyping hematopoietic colonies or by means of next-generation sequencing. Stem cells and progenitor cells were isolated to study the effect of mutation order on mature and immature hematopoietic cells. RESULTS: The age at which a patient presented with a myeloproliferative neoplasm, acquisition of JAK2 V617F homozygosity, and the balance of immature progenitors were all influenced by mutation order. As compared with patients in whom the TET2 mutation was acquired first (hereafter referred to as TET2-first patients), patients in whom the Janus kinase 2 (JAK2) mutation was acquired first (JAK2-first patients) had a greater likelihood of presenting with polycythemia vera than with

All MPNs arise from precursors of the myeloid lineages in the bone marrow. The lymphoid lineage may produce similar diseases, the lymphoproliferative disorders (acute lymphoblastic leukemia, lymphomas, chronic lymphocytic leukemia and multiple myeloma). Most Philadelphia chromosome negative cases have an activating JAK2 or MPL mutation.[4] Mutations in CALR have been found in the majority of JAK2 and MPL-negative essential thrombocythemia and myelofibrosis.[5][6] In 2005, the discovery of the JAK2V617F mutation provided the first evidence that a fraction of persons with these disorders have a common molecular pathogenesis.[7][8][9][10] Patients with JAK2V617F-negative polycythemia vera are instead positive for another class of activating JAK2 mutations - the JAK2 exon 12 mutations.[11]. A subset may additionally have mutations in the genes LNK, CBL, TET2, ASXL1, IDH, IKZF1 or EZH2; the pathogenetic contribution of these mutations is being studied.[citation needed]. ...

Andrew Latimer (17 May 1949, Guildford, Surrey, England) is an English musician and composer who is a founder member of the progressive rock band Camel. Best known as a guitarist and singer, Latimer is a flautist and keyboardist as well. Latimers most common guitar of choice is a Gibson Les Paul, but he is also known for playing Fender Stratocasters and other guitars. From the 1990s onward, he also played a Burny Super Grade, an 80s copy of the Gibson Les Paul Model. The amplifiers he uses range from Fender, Vox, and Marshall. He established a music production named Camel Productions which released Camels new albums: Dust And Dreams (1991), Harbour of Tears (1996), Rajaz (1999) and A Nod and a Wink (2002). In May 2007, Susan Hoover, Latimers wife, announced through the Camel Productions website and newsletter that Latimer had suffered from a progressive blood disorder polycythaemia vera since 1992, which had later progressed to myelofibrosis. This was part of the reason why Camel ceased ...
