Evaluation of the sphingolipidomic profile in women with anorexia nervosa: relationships with parameters related to body composition, cardiovascular function, glucometabolic homeostasis, and lipoprotein metabolism

Abstract: Anorexia nervosa (AN) is a metabolic-psychiatric disease, in which, besides an extremely low body weight, there is a paradoxical dyslipidemia. Objectives. The aims of the present study were (1) to carry out a sphingolipidomic profiling in a group of women with AN (n = 28; body mass index [BMI]: 15.54 [13.96–16.32] kg/m2) compared to a normal-weight healthy (NWH) group (n = 30; BMI: 22.05 [19.67–23.72] kg/m2), and (2) to correlate plasma levels of single or total sphingolipids with parameters related tobody composition, cardiovascular function, glucometabolic homeostasis, and lipoprotein metabolism. Results. Age, weight, BMI, fat mass (FM) (%), and fat-free mass (FFM) (kg) were significantly lower in women with AN than in the NWH group. Women withAN exhibited lower values of both systolic and diastolic blood pressure than the NWH group. Glucose, insulin, and HOMA-IR were significantly lower in women with AN than in the NWH group. Finally, C-reactive protein (CRP) was significantly higher in NWH women than in those with AN. Among all the sphingolipid species evaluated, 16 were significantly increased in AN (single species or whole family of summed species), while 6 were decreased. The highest significant correlations of sphingolipidomic profiling were mainly concentrated within parameters related to body composition. Conclusions. Women with AN have a specific sphingolipidomic profile that could hopefully serve as a markerfor monitoring treatment effectiveness. These data cannot be made publicly available as they include sensitive information, but they can be made available upon reasonable request of interested researchers to the corresponding author, who will forward a data transfer agreement request to the relevant Ethical Committee.
