Serum ESF titers were measured in 42 polycythemic patients using the fetal mouse liver cell bioassay. ESF titers in patients with secondary polycythemia differed significantly from those in patients with polycythemia vera (p less than 0.0001). Among the 21 patients with secondary polycythemia, 1 patient had an ESF titer less than 10 mU/ml (the lower limit of sensitivity) and 20 had ESF titers t...

BACKGROUND AND OBJECTIVE It has been suggested that the determination of serum erythropoietin (sEpo) may be useful in distinguishing between polycythemia vera (PV), relative polycythemia and secondary polycythemia (SP), but no conclusive evidence has yet been provided for this. In the present work, we evaluated the role of sEpo in the differential diagnosis of polycythemia vera and its usefulne...

OBJECTIVE To present a case with nephrotic syndrome due to minimal change disease and polycythemia. CLINICAL PRESENTATION AND INTERVENTION A 20-year-old female was admitted to our clinic for edema and severe proteinuria present with minimal change disease since the age of 7 years. Polycythemia was found during the last activation of nephrotic syndrome. The patient was placed on glucocorticoid...

The effects of primary and secondary polycythemia on circulatory and ventilatory events have been the center of much investigation. There has, however, been sharp disagreement about the clinical merit of phlebotomy in cases of secondary polycythemia. Howarth, et al.' and Lewis, et al.,' among others, have concluded, although for somewhat different reasons, that therapeutic phlebotomy is detrime...

Abstract: Objectives: The aim of this study was to estimate the prevalence anemia among COVID-19 patients in Saudi Arabia and evaluate their hematological parameters. Materials Methods: A descriptive, cross-sectional, hospital-based conducted between February 2021 March 2021, data collection covered period September 2020 2021. All were hospitalized for confirmed COVID-19. Results: total 6048 in...

ary polyeythemia is diagnosed when the patient has polycythemia associated with cyanotic heart disease or lung disease in the absence of leukoeytosis, high platelet count, and splenic enlargement. The differentiation of polycythemia vera from secondary polycythemia is sometimes a difficult task. Ratto, Briscoe, Morton, and Comroel have discussed the theoretical reasons that make this distinctio...

The regulation of erythropoiesis was control cultures. Erythropoietin was studied in patients with polycythemia ineffective in stimulating iron incorpovera and chronic granulocytic Ieukeration into heme in five patients with mia (CGL). An in vitro culture system polycythemia vera. The marrow rewas employed to determine the response to erythropoietin in vitro was sponse of bone marrow cells to e...

A 59-year-old female with diabetes mellitus presented with hypercalcemia and polycythemia. Her serum calcium and intact parathyroid hormone (iPTH) levels were increased, and Tc-99m sesta-MIBI scanning showed hot uptake in the lower portion of the left thyroid lobe. After parathyroidectomy, her calcium, iPTH, and polycythemia were normalized. In conclusion, the differential diagnosis of polycyth...
