  Sloan-Kettering - Uncommon Myeloproliferative Disorders
Myeloproliferative disorders are diseases in which too many of certain types of blood cells -- monocytes, platelets, fibroblasts, red blood cells -- are made in the bone marrow, the spongy tissue inside the large bones in the body where red and white blood cells and platelets are made.
CMML is classified either as a myeloproliferative disease or a myelodysplastic syndrome and its treatment depends in part on how it manifests itself, but often entails blood transfusions and sometimes oral or intravenous chemotherapy to control the disease.
Polycythemia vera, a disease of the hematopoietic stem cells (cells that give rise to blood cells) is characterized by the overproduction of red blood cells by the bone marrow.

 Myeloproliferative disease - Wikipedia, the free encyclopedia
The myeloproliferative diseases are a group of diseases of the bone marrow where excess cells are produced.
They are related to, and may evolve into, myelodysplastic syndrome and acute myeloid leukemia, although the myeloproliferative diseases on the whole have a much better prognosis than these conditions.
The concept of myeloproliferative disease was first proposed in 1951 by the eminent hematologist William Dameshek.

 Myeloproliferative Disorders
Myeloproliferative disorders (MPDs) are characterized by the clonal proliferation of one or more hematopoietic cell lineages, predominantly in the bone marrow but sometimes in the liver and spleen as well.
The role and benefit of using chemotherapeutic agents early in the disease to reverse the fibrosis is highly controversial, and randomized clinical trials are needed to address this issue.
The incidence of the disease (2.38/100,000 population/year in Olmsted County, MN) is the lowest among the chronic myeloproliferative disorders.

With regard to the PV, the author notes in the summary that a better understanding of the influence of various therapies on outcome of the disease has been achieved, and a better understanding of the transformation of the disease into other lesions has been forthcoming.
With regard to the AMM, it is noted that the central role of the megakaryocyte in the pathology and pathophysiology of the disease seems unquestionable and that newer treatments for the disease have been proposed.
Finally, with regard to the PT, it is noted that genetic studies of the lesion depict it as a clonal hemopathy and that numerous trials of therapy have now been reported.

Usually increased in allergy, parasitic infestations, tuberculosis, brucellosis, collagen disease, Hodgkin's disease, myeloproliferative diseases, and the acute hypereosinophilic syndrome; increased also in angioneurotic edema, dermatitis, thymic disorders, radiotherapy, splenectomy, convalescence from a febrile illness, and hypoadrenocorticism (Addison disease).
Toxocaral disease (visceral larva migrans) is a typical parasitic disease in which eosinophil counts (eosinophils >30% on differential) are usually elevated.
This condition may not be a true leukemic myeloproliferative disease, although concepts of HES are controversial.

The myelodysplastic/myeloproliferative diseases (MDS/MPD) are clonal myeloid disorders that possess both dysplastic and proliferative features and that are not properly classified as either myelodysplastic syndromes (MDS) or chronic myeloproliferative disorders (CMPD).
In general, the treatment of these diseases is tailored to the manifestations, myeloproliferative or myelodysplastic, that predominate in the individual patient.
Myelodysplastic/Myeloproliferative Disease, Unclassifiable (MDS/MPD-U) (also known as mixed myeloproliferative/myelodysplastic syndrome, unclassifiable and “overlap” syndrome, unclassifiable) shows features of both myeloproliferative disease and myelodysplastic disease but does not meet the criteria for any of the other MDS/MPD entities.

 NIH Guide: CELLULAR AND GENETIC DISCOVERY TOWARD CURATIVE THERAPY IN MYELOPROLIFERATIVE DISORDERS (MPD)
MPD represents a broad range of clinical entities, which creats difficulties in prompt assignment of diagnosis, prediction of prognosis, characterization of disease evolution, and an orderly approach to research on the etiology and progression of disease.
Myeloproliferative disorders are considered clonal hematopoietic stem cell disorders characterized by excessive proliferation and production of one or more of the myeloid cells and are classified according to the predominant cells, such as chronic myelogenous leukemia (CML), chronic eosinophilic leukemia (CEL), polycythemia vera (PV), essential thrombocythemia (ET), and chronic idiopathic myelofibrosis (CIMF).
Laboratory and clinical correlative studies may be used to define meaningful disease characteristics that will improve early diagnosis and serve as basis for the development of novel, safer, and more effective therapy.

The NH(2)-terminal coiled-coil domain and tyrosine 177 play important roles in induction of a myeloproliferative disease in mice by Bcr-Abl.These studies directly demonstrated the important roles of Bcr sequences in induction of MPD by Bcr-Abl.
We found that the NH(2)-terminal coiled-coil (CC) domain was both essential and sufficient, even though not efficient, to activate Abl to induce an MPD in mice.
We have also shown that the Abl kinase activity within Bcr-Abl is essential for Bcr-Abl leukemogenesis, yet activation of the Abl kinase without Bcr sequences is not sufficient to induce MPD in mice.

 Familial Myeloproliferative Disease   (Site not responding. Last check: 2007-10-09)
The Myeloproliferative Disorders (MPDs) have been shown to arise from clonal expansion of a pluripotential hematopoietic precursor cell (PHPC) that possesses a growth advantage over other polyclonally derived PHPC's but still retains its pluripotentiality.
The occurrence of mixed phenotypes in familial MPD is entirely consistent with the accepted theory of MPD as a disease of the pluripotential hematopoietic precursor cell that manifests phenotypic heterogeneity of the expanded clone.
Transformations from one phenotypic variant to another during the course of MPD are common, and it would be surprising if only a single MPD variant were to appear in all involved members of a family with MPD.
