Determinants of Magnitude of Pseudohyperkalemia in Thrombocytosis
نویسندگان
چکیده
The release of potassium from platelets is a well-known cause of pseudohyperkalemia in thrombocytosis. In predicting the magnitude of pseudohyperkalemia associated with thrombocytosis, previous investigations considered only the amount of potassium released from platelets during blood clotting, although the increment in serum potassium during blood clotting depends on the quantity of potassium released from platelets as well as the volume of distribution of the released potassium, which is inversely proportionate to the hematocrit. The present study proposes a new mathematical formula to predict the magnitude of increase in serum potassium during blood clotting, and accuracy of this formula has been tested in a patient with thrombocytosis.

Hyperkalemia is a potentially lethal condition. Pseudohyperkalemia should be always excluded before implementing treatment to prevent inappropriate cause of hypokalemia - equally a potentially lethal condition.

BACKGROUND Hyperkalemia is a potentially life-threatening medical condition; on the other hand pseudohyperkalemia is a benign entity, which should be suspected when serum potassium is elevated without concomitant electrolyte imbalances or remarkable degree of renal dysfunction. Patients seldom have the classical manifestations of hyperkalemia. Failure to recognize this condition causes anxiety ...

Background: We aimed to investigate the etiologic causes and the existence of Janus kinase 2 mutation (JAK2) in cases with thrombocytosis. Methods: In this retrospective study, patients, who were admitted to hematology clinic with thrombocytosis between 2013 and 2015, were investigated in terms of the etiological causes of thrombocytosis and the existence of JAK2 mutation. Results: We retrospe...

Neonatal thrombocytosis is a very rare phenomenon in infants born to addict mothers. It can be due to opioids withdrawal and occurs a few days after delivery. The etiology is unknown and it is eradicated gradually without any complication. The reported neonate was born to a heroin addict mother who has used methadone during pregnancy. The neonate was admitted in 14th day of life in neonatal int...
