Abstract

Ketones can reactivate the production of fetal hemoglobin (HbF) in vitro and in vivo. A reactivation of HbF by ketones, which are generated during starvation, remains largely speculative. Therefore, we investigated HbF in 31 women with anorexia nervosa or bulimia, using both of these as models of intermittent starvation ketosis. For comparison, we also studied 42 female control subjects matched for age. beta-Hydroxybutyrate levels were higher in patients than in controls (460 +/- 90 v 110 +/- 20 mumol/L; P < .0001). We correlated beta-hydroxybutyrate, metabolic, and hematologic parameters with HbF. HbF was measured with high pressure liquid chromatography. The data were analyzed with logistic regression analysis. An elevated HbF fraction (> 0.87%) was observed four times as often in patients than in controls (29% v 7%, P = .01). After adjustment for age, we found HbF elevations associated with beta-hydroxybutyrate levels (P = .005). No other correlations between the various metabolic/ hematologic parameters and HbF were significant. In conclusion, beta-hydroxybutyrate generated in starvation is associated with increased levels of HbF. Thus, unrestrained lipolysis can produce beta-hydroxybutyrate in sufficient quantities to indu...Continue Reading
