Vyas, Kaetan J., David Danz, Robert H. Gilman, Robert A. Wise, Fabiola León-Velarde, J. Jaime Miranda, and William Checkley. Noninvasive assessment of excessive erythrocytosis as a screening method for chronic mountain sickness at high altitude. High Alt Med Biol 16:162-168, 2015.--Globally, over 140 million people are at risk of developing chronic mountain sickness, a common maladaptation to l...
We postulate that repeated pregnancy loss, intrauterine growth restriction, and preeclampsia are caused by impaired elevation of uterine blood flow due to disturbed arteriogenesis of the uterine arcade. This hypothesis is based on the observation that pregnant human erythropoietin-overexpressing (plasma levels elevated 12-fold) mice (termed tg6 mice) suffering from excessive erythrocytosis gene...
Several etiologies have been proposed for erythrocytosis associated with uterine leiomyoma. We report a case of erythrocytosis associated with a large uterine leiomyoma, in which specific immunostaining for erythropoietin was positive. A 55-year-old woman, gravida 0, para 0, was referred to our hospital for treatment for a large uterine myoma and erythrocytosis. She had no vaginal bleeding afte...
The transcription of the erythropoietin (EPO) gene is tightly regulated by the hypoxia response pathway to maintain oxygen homeostasis. Elevations in serum EPO level may be reflected in an augmentation in the red cell mass, thereby causing erythrocytosis. Studies on erythrocytosis have provided insights into the function of the oxygen-sensing pathway and the critical proteins involved in the re...
Hemoglobin (Hb) Sherwood Forest is a rare high-affinity hemoglobin first described in 1977, arising from an Arg to Thr substitution at codon 104 of the beta chain. This hemoglobin variant has been identified in few individuals and has been associated with a compensatory erythrocytosis in the homozygous state. Prior scarce case reports have noted that heterozygotes for this variant are phenotypi...
Background: Post-transplant erythrocytosis (PTE) is characterized by persistent hematocrit level above 51% that develops in 10-20% of kidney recipients, mostly 2 years after kidney transplantation. PTE is self limited in 25% of the patients but can be persistent in other patients with an increased susceptibility for thrombosis. The purpose of this study was to identify the risk factors for deve...
Anemia is a common complication in end-stage renal disease (ESRD) patients. On the other hand, idiopathic erythrocytosis is extremely rare, with only a few cases reported in the literature. We present a case of erythrocytosis that developed after initiating hemodialysis. A 68-year-old male with a history of ESRD secondary to diabetes presented with erythrocytosis that started a few months after...
