To date, the diagnosis of polycythemia vera (PV) relies on clinical criteria. We have recently described the overexpression of a hematopoietic receptor, polycythemia rubra vera-1 (PRV-1), in patients with PV. Here, we report a quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) assay for the measurement of PRV-1 mRNA levels. We have determined PRV-1 expression in 71 patients w...

We searched for JAK2 exon 12 mutations in patients with JAK2 (V617F)-negative myeloproliferative disorders. Seventeen patients with polycythemia vera (PV), including 15 sporadic cases and 2 familial cases, carried deletions or duplications of exon 12 in circulating granulocytes but not in T lymphocytes. Two of the 8 mutations detected were novel, and the most frequent ones were N542-E543del and...

During the study of an inbred strain of Wistar rats which spontaneously develop hypertension when they reach a weight of approximately 150 g, it was found that these animals also develop an erythrocytosis. A significant increase in red cell count was observed in spontaneously hypertensive (SH) rats (8-11 x 10(6) RBC/mm(3)) when compared with normotensive rats (6-7 x 10(6) RBC/mm(3)) of the same...

Every day, doctors are faced with severe patients various diseases, which is aggravated due to comorbidities. However, the management of such complicated surgical pathologies, treatment involves exclusively intervention. The case describes a patient critical aortic valve stenosis, hemodynamically significant coronary metabolic and hematological disorders, as well respiratory pathology. In order...

Hemoglobin Crete, 1 29 (H7) ala -k pro, is #{149} new mutant hemoglobin (Hb) with high oxygen affinity that was discovered in a Greek family in various combinations with #{176}and #{244} ’-thaIassemia. The propositus. who presented an unusual clinical picture of an “overcompenseted” hemolytic state. with erythrocytosis. splenomegaly. abnormal red cell morphology, and marked erythroid hyperplasi...

Polycythaemia may complicate or be the presenting feature ofa wide variety of different pathologies. Early diagnosis and treatment of primary polycythaemia will significantly reduce the morbidity and mortality associated with this condition. Patients with a raised packed cell volume are divided into those with a raised red cell mass (absolute polycythaemia), and those with a red cell mass withi...

Congenital erythrocytosis (CE) is a rare and heterogeneous disease. The high oxygen affinity hemoglobin (Hb) variants are the most common cause of CE. Herein, we report a Korean patient with isolated erythrocytosis. A 25-year-old man was referred to our hospital for evaluation of high Hb level (Hb 20.4 g/dL, hematocrit 58%, reticulocyte count 2.90%, white blood cell count 6.83×10⁹/L, and platel...

Studies of marrow regulation were carried out in two families with recessively expressed erythrocytosis. The erythrocytosis in the affected individuals was associated with increased erythropoietin (ESF) production. However, hormone production was uninfluenced by alterations In the 02 carrying capacity of the blood when the hematocrit was lowered acutely by phlebotomy. Hemoglobin and red cell fu...
