245 Possible Causes for Erythrocytes Increased, Erythrocytosis, Polycythemia

  • Myeloproliferative Disease

    Megakaryocyte and late erythroid progenitors were dramatically increased, with only modest expansion of early erythroid progenitors.[] Bone marrow fibrosis is also detected in the spent phase of chronic myelogenous leukemia and polycythemia vera. See Workup for more detail.[] erythrocyte production Lymphatic decompression injury Lymphatic malformation Lymphatic vesicle Lymphoreticular injury Megakaryocytic hyperplasia of bone marrow Mild bone[]

  • Polycythemia Vera

    The increased production of erythrocytes leads to elevated hematocrit and hemoglobin counts.[] […] as a primary polycythemia.[] ERYTHROCYTOSIS AND POLYCYTHEMIA VERA 1. In patients with erythrocytosis, which of the following is not characteristic of polycythemia vera?[]

  • Secondary Polycythemia

    And although these findings imply an increase in erythrocyte counts, they are not reliable indicators of polycythemia.[] Out of these 53 patients, 28 (53%) patients had PV and 25 (47%) patients had secondary erythrocytosis.[] Polycythemia rubra vera, or primary erythrocytosis (an increase of red blood cell mass) results from unstimulated over production of erythrocytes.[]

  • Stress Polycythemia

    The increased erythrocyte production results in thickening of the blood and an increased tendency toward clotting.[] Called also benign or stress erythrocytosis, Gaisbцck disease, pseudopolycythemia, and benign, chronic relative, hypertonic, or spurious p. Medical dictionary. 2011.[] Detection and accurate diagnosis of erythrocytosis is important regardless of its cause.[]

  • Polycythemia Neonatorum

    […] in the production of erythropoietin, hence an increased production of erythrocytes.[] Neonatal polycythemia often occurs in children with ABO or Rh incompatibility.[] […] conjunctivitis Inclusion: Ophthalmia neonatorum due to gonococcus D45 Polycythemia vera excludes: familial polycythemia (D75.0) secondary polycythemia (D75.1) D75.0 Familial erythrocytosis[]

  • Metastatic Renal Cell Carcinoma

    Polycythemia has also been described in mRCC patients. mRCC may be accompanied by amyloidosis, although its pathogenesis remains unclear.[] Paraneoplastic syndromes Around 25% of RCC patients will develop a paraneoplastic syndrome 19-21 : hypercalcemia (20%) hypertension (20%) polycythemia : from erythropoietin[] […] abdominal mass; [9] malaise, which is a general feeling of unwellness; [9] weight loss and/or loss of appetite; [10] anaemia resulting from depression of erythropoietin ; [8] erythrocytosis[]

  • Familial Polycythemia

    The increased erythrocyte production results in thickening of the blood and an increased tendency toward clotting.[] Their differentiation from polycythemia vera (PV) is crucial to avoid therapy which is otherwise reserved for PV patients.[] In some cases, the cause of erythrocytosis is unknown. Familial erythrocytosis can have different inheritance patterns depending on the gene involved.[]

  • Erythrocytosis

    Moreover, in case of low environmental partial pressure of oxygen, the number of erythrocytes automatically increases to preserve sustained oxygen delivery.[] Polycythemia Vera Erythremic Polycythemia and Erythrocytosis Last Updated on Wed, 04 May 2016 Hematology Increases in erythrocytes, hemoglobin, and hematocrit above the normal[] In addition, EPO levels are a very useful tool in recognizing the nature of erythrocytosis.[]

  • Cyanotic Congenital Heart Disease

    Repeated phlebotomy causes iron deficiency with microcytic erythrocytes, which increases the whole blood viscosity and, therefore, can potentially accentuate rather than decrease[] A rise of hematocrit above 75% resulted in return of symptoms, possibly due to marked increase of blood viscosity.[] […] cyanotic congenital heart disease who are not candidates for or had failed Fontan operation, palliation with an axillary arteriovenous fistula did not improve cyanosis or polycythemia[]

  • Chronic Obstructive Pulmonary Disease

    Chronic hypoxaemia increases 2,3-diphosphoglycerate (2,3-DPG) in erythrocytes, shifting the dissociation curve to the right and therefore increasing oxygen delivery to the[] This V/Q mismatch results in rapid circulation in a poorly ventilated lung, leading to hypoxemia and polycythemia.[] […] oxygen therapy (LTOT) In the first Denver studies of ambulatory oxygen, patients with chronic stable hypoxemia experienced remarkable reductions in pulmonary hypertension and erythrocytosis[]
