Neutrophil myeloperoxidase measurement uncovers masked megaloblastic anemia.
We report the observation of a high neutrophil myeloperoxidase activity (MPXI) in patients with megaloblastic anemia. MPXI is rapidly measured as part of an automated complete blood count (Technicon H*1, Technicon Instruments Corp, Tarrytown NY). We describe the range of MPXI levels in healthy and patient populations and in 10 cases of megaloblastic anemia, including five having elevated mean c...

متن کاملMasked polycythaemia vera is genetically intermediate between JAK2V617F mutated essential thrombocythaemia and overt polycythaemia vera
Polycythaemia vera (PV) can be defined as a myeloproliferative neoplasm (MPN) with erythrocytosis and JAK2V617F (or an equivalent marker of clonality). While these simple criteria are sufficient for most cases of overt PV, an estimated 10–15% of PV patients do not have an elevated haemoglobin concentration (Hb) and may mimic JAK2-positive essential thrombocythaemia (ET). This poses a problem fo...
متن کاملSimultaneous occurrence of multiple aetiologies of polycythaemia: renal cell carcinoma, sleep apnoea syndrome, and relative polycythaemia in a smoker with masked polycythaemia rubra vera.
A 58 year old male heavy smoker presented with intracranial haemorrhage and erythrocytosis. Four aetiologies of polycythaemia--polycythaemia rubra vera (PRV), renal cell carcinoma, sleep apnoea syndrome, and relative polycythaemia--were found to be associated with the underlying causes of erythrocytosis. He did not fulfill the diagnostic criteria for PRV at initial presentation, but an erythrop...
متن کاملDelirium Precipitated by Polycythaemia
While there was no denial of the organic etiology of delirium, based on a huge body of references that surpassed million hits related to the subject. The etiologies of delirium are diverse and multifactorial and often reflect the pathophysiological consequences of an acute medical illness, medical complication or drug intoxication. Delirium can have a widely variable presentation, and is often ...
