  Complications Portal hypertension may result in variceal bleeding, ascites and hepatic encephalopathy. Hepatic or portal vein thrombosis may also occur. Splenic infarction: usually self-limited and treated with fluids and opiate analgesics. [patient.info]

  For example, XL019 was halted in a Phase I trial owing to peripheral neuropathy despite dose reductions. 50 Phase III trials of fedratinib (SAR302503) found significant neurotoxicity, specifically Wernicke’s encephalopathy, 51 while studies with lestaurtinib [dovepress.com]

Hyperuricemia is due to enhanced turnover of hematopoietic tissue. 26 Mutation testing Testing for the JAK2 V617F mutation should be performed early during the diagnostic workup of suspected MPNs. [mpncanada.com]

Of patients with Budd-Chiari syndrome (hepatic-inferior vena cava obstruction), 10% to 13% have coexisting PV; therefore, testing for the presence of JAK2 V617F mutation is part of the routine workup for unexplained liver thrombosis. [clevelandclinicmeded.com]

  The study by Tefferi et al. [14] also showed some similarities with our study; they found older age group, normal to high platelet count and blast percentage et al. [15] was also in line with our observations. [ijpmonline.org]

  Decreasing platelet counts in ET to below 600 x 10 9 /L can decrease thrombotic complications. 46 High platelet counts (>1,000 x 10 9 /L) are associated with acquired von Willebrand disease resulting from the adsorption of von Willebrand multimers onto [clevelandclinicmeded.com]

Also, these cases may represent a clonal disorder with genetic instability allowing evolution to a more aggressive malignancy. [13] The prognosis in our patient could not be judged following ATT since the child was lost to follow up. [ijcasereportsandimages.com]

Even though the discovery of the Janus kinase 2 (JAK2), thrombopoietin receptor (MPL) and calreticulin (CALR) mutations have brought new insights into the complex pathogenesis of MPNs, the etiology of fibrosis is not well understood. [einstein.pure.elsevier.com]

Etiology The etiology of chronic IMF is unknown. Nonrandom chromosome abnormalities such as 9p, 20q-, 13q-, trisomy 8 or 9, or partial trisomy 1q are common, but no cytogenetic abnormality specific to the disease has been identified. [theoncologyinstitute.com]
