polycythemia vera/hypoxia

Red blood cell metabolism was studied in male patients with polycythemia rubra vera (Vaquez disease) and compared to a reference sample of 74 healthy adults. A total of seventeen enzyme activities and seventeen metabolite concentrations were determined. In addition to the modifications of the

Thromboses represent a major cause of morbidity and mortality in polycythemia vera but the contributing mechanisms are not fully described. To evaluate whether environmental conditions such as altitude/hypoxia could impact thrombosis history, we retrospectively analyzed thrombosis history in 71

METHODS Female, 64 FINAL DIAGNOSIS: Polycythemia rubra vera Symptoms: Burning pain • cramps • hypesthesia • itching • paresthesia METHODS - Clinical Procedure: - Specialty: Neurology. OBJECTIVE Unusual clinical course. BACKGROUND The association between polycythemia vera and peripheral neuropathy

Leg ulcers are a frequent and serious complication of polycythemia vera (PV). They are caused by a synergic action of vascular, neurological and infectious physiopathologic mechanisms. Furthermore, cytostatic therapies commonly employed to control the myeloproliferative disease negatively interfere

In this retrospective investigation from Malmö, a city well-suited for epidemiologic studies, 177 patients (88 males and 89 females) with polycythemia vera (PV) were identified between 1950 and 1984. The incidence rate (number of cases/100,000/yr) in both sexes increased significantly, being 1.0 in

This review will focus on the molecular basis of certain polycythemic disorders. Primary polycythemias are characterized by acquired somatic or inherited germ-line mutations expressed within hematopoietic progenitors that cause increased accumulation of red blood cells. Polycythemia vera (PV), an

A 38-year-old male with a prior diagnosis of severe OSA (apnea-hypopnea index [AHI] 99/h) presented for transfer of care. He was successfully titrated to CPAP of 10 cm H₂O at an outside laboratory and was compliant with therapy with residual AHI 1.9/h. On presentation, he was

BACKGROUND Causes of leg ulcers vary widely, although venous insufficiency and peripheral arteriopathy are most common. Ulcers are much rarer in patients treated by hydroxyurea. METHODS A 66-year-old woman who had been treated with hydroxyurea for polycythemia vera for four years came to our

Symptomatic erythrocytosis developed in a 59-year-old man with polycystic kidney disease (PKD) while he was receiving maintenance hemodialysis. Major clinical and laboratory data suggested a diagnosis of polycythemia vera (PV), despite a normal serum alkaline phosphatase level and leukocyte count.

Polycythemia vera (PV) is one of the myeloproliferative diseases, and, as such, is an example of clonal hematopoiesis. The progeny of a single, abnormal, hematopoietic stem cell gain a growth advantage over their normal counterparts resulting in overproduction of red cells generally accompanied by

There is no single diagnostic marker for the only known type of primary acquired erythrocytosis, polycythemia vera (PV). The Polycythemia Vera Study Group (PVSG) used a combination of major and minor diagnostic criteria. However, these guidelines have some limitations and in the presence of newer
