ABSTRACT
Introduction:
Anorexia nervosa (AN) can co-occur with hypercarotenemia, a clinical condition characterized by elevated ß-carotene in plasma and skin tissue. Carotenoids have known anti-obesogenic effects in adipocyte biology. Thus, carotenoids may potentially play a retarding role in weight gain during the recovery of AN patients. This study evaluated the plasma carotenoid profile and subcutaneous adipose tissue (SAT) in a cohort of AN patients and normal weight (NW) controls.Methods:
Plasma concentrations of α-carotene, ß-carotene, ß-cryptoxanthin, and lycopene were determined by HPLC analysis. SAT thicknesses were measured by a highly accurate and reliable ultrasound technique. Information on dietary intakes were collected by repeated 24-h recalls.Results:
Sixty-two females (AN n = 18, NW n = 44) were included. The concentrations of ß-cryptoxanthin (p = 0.045) and lycopene (p = 0.004) were significantly lower in AN patients. ß-carotene levels were higher in AN patients (n.s.) and α-carotene did not differ significantly. SAT thickness was significantly lower in AN patients compared to controls (p < 0.001). ß-carotene was significantly negative (r s = -0.471) and lycopene significantly positive (r s = 0.366) correlated with SAT. The correlation of ß-carotene and SAT was even higher in the AN group alone (r s = -0.742). Also, ß- cryptoxanthin and the sum of provitamin A carotenoids were correlated to SAT (r s = -0.647 and r s = -0.746, respectively) in AN patients. Fruits and vegetable intake did not differ significantly between AN and NW but adjusted for SAT, AN patients consumed relatively higher amounts (p = 0.006).Conclusion:
Higher plasma ß-carotene concentrations were associated with reduced SAT levels, most probably due to a reduced ability of the remaining adipose tissue to store carotenoids. Thus, the antiobesity effects of carotenoids might impact the treatment success of undernutrition and AN. A systemic carotenoid overload may contribute to changes in adipogenesis and metabolic capacities for energy storage. Therefore, high plasma ß-carotene may be a marker of delay in weight recovery in AN patients. Interventional studies should consider including carotenoid-status in AN treatment.
