简要总结
In around 90% of the patients with MPNs, an acquired mutation that promotes JAK/STAT signaling is identified [3, 4]. The JAK/STAT pathway transduces signals from cytokines including erythropoietin, thrombopoietin, and granulocyte colony-stimulating factor.24 A point mutation that activates JAK2, JAK2V617F, is present in around 95% of patients with PV and 40% to 60% of patients with ET and MF
详细描述
All patients will be subjected to a thorough assessment of history, complete clinical examination, and investigations as complete blood picture including neutrophil-lymphocyte ratio which will be analyzed with automated blood count analyzers, serum uric acid, serum creatinine and lipid profile. All patients will undergo carotid imaging using Colour Doppler ultrasonography for assessment of carotid plaque burden.
The control group will undergo carotid ultrasonography who will be recruited among apparently healthy volunteers aiming to match the patient group regarding age, sex and classical risk factors for atherosclerosis as arterial hypertension, hyperlipidemia, diabetes, smoking or obesity.

主要结局
Neutrophil-Lymphocyte Ratio in Patients with Philadelphia Negative Myeloproliferative Neoplasms
时间窗: baseline
All patients will be subjected to a thorough assessment of history, complete clinical examination, and investigations as complete blood picture including neutrophil-lymphocyte ratio which will be analyzed with automated blood count analyzers, serum uric acid, serum creatinine and lipid profile.
Carotid Plaque Burden in Patients with Philadelphia Negative Myeloproliferative Neoplasms
时间窗: baseline
All patients will undergo carotid imaging using Colour Doppler ultrasonography for assessment of carotid plaque burden. Extracranial carotid arteries were divided into three sectors on each side: common carotid artery and its bulb, internal carotid artery, and external carotid artery. At least one plaque in any sector was scored 1 point, while the absence of plaques was scored 0. Thus, the carotid plaque score ranged from 0 (absence of plaques) to 6 (plaques in all sectors)
