Abstract
AIMS/BACKGROUND
Recently, there has been considerable interest in the potential anti-diabetic effects of erythropoietin in animal models. It is not known, however, whether endogenous erythropoietin is associated with glucose regulation in humans.
METHODS
We evaluated the longitudinal relationship between endogenous erythropoietin at 3-months postpartum and glucose homeostasis at 12-months postpartum in a cohort of 229 women with varying degrees of glucose intolerance in their recent pregnancy, a model of the early natural history of pre-diabetes/diabetes. The women reflected the full spectrum of glucose tolerance in pregnancy from normal (n=63) to mildly abnormal (n=65) to gestational impaired glucose tolerance (n=46) to gestational diabetes (n=55), and hence a broad range of future diabetic risk.
RESULTS
At 3-months postpartum, there was no difference in serum erythropoietin between these 4 groups (p=0.22). After covariate adjustment, erythropoietin was not associated with beta-cell function, insulin sensitivity, or glycemia at either 3- or 12-months postpartum. On multiple linear regression analyses, however, erythropoietin at 3-months emerged as an independent predictor of both systolic (beta=0.51326, p=0.003) and diastolic blood pressure (beta=0.3321, p=0.01) at 12-months.
CONCLUSION
Endogenous erythropoietin is not associated with glucose homeostasis early in the natural history of metabolic disease, but may be relevant to vascular health.
