Persistent neutrophilia progressing to polycythemia vera

Treatment of polycythemia vera.

BACKGROUND AND OBJECTIVE Current guidelines for the management of patients with polycythemia vera (PV) derive from a few clinical trials and several uncontrolled clinical studies. The purpose of this paper is to critically review the available evidence in literature for selecting the best treatment in the single patient. METHODS The authors have been working in this field contributing origina...

Pathogenesis of polycythemia vera.

BACKGROUND AND OBJECTIVE Polycythemia vera (PV) is an acquired clonal myeloproliferative disorder characterized by increased production of mature red cells. We still lack a molecular target responsible for this disorder; however, recent investigations have focused on a number of molecules involved in signal transduction pathways mediated by erythropoietin (Epo) and other growth factors. Here we...

Muramidase in polycythemia vera.

Polycythemia vera: a review.

Polycythemia vera (PV) is a clonal stem cell disorder characterized by increased erythrocyte production. Its etiology is not fully understood, and hemorrhage, thrombosis, and hyperviscosity may occur at any time during the course of this disorder. Treatment depends on the most affected cell type, duration and severity of the condition, and patient age. PV treatment can involve phlebotomy, admin...

Immunotherapy and polycythemia vera

Polycythemia vera (PV) is a chronic myeloproliferative disorder characterized by abnormal growth of erythroid precursors in the bone marrow. Almost all patients with PV, around 97%, have a mutation in Janus kinase 2 (JAK2). It is through the activation of JAK/Signal Transducers and Activators of Transcription (STAT) protein signaling pathway that the JAK2 mutation is thought to induce cellular ...
