Abstract

Introduction: Anorexia nervosa (AN) is an eating disorder characterised with extremely low weight. Adipokines are adipose tissue-derived substances that show a wide spectrum of biological activities. We aimed to assess selected adipokine levels in women with AN before and after nutritional intervention. We also sought to examine whether BMI is the only confounding factor influencing adipokine assessment in AN.

Material and methods: Sixty-five women participated in the study: 20 individuals with AN before any treatment, 18 AN patients after nutritional intervention lasting for at least six months, and 27 women as controls. In all participants blood collection and anthropometric measurements were performed. ELISA was used for evaluation of leptin receptor, adiponectin and its isoforms, and resistin. Leptin was assessed with RIA, and visfatin was measured with EIA assay.

Results: Leptin and free leptin index (FLI) were lowest in treatment–naïve AN women. HMW-adiponectin and visfatin were enhanced in AN. Other adipokine levels showed no significant differences. When two subsets of anorexia nervosa were compared, only leptin, leptin receptor, and FLI were markedly different. When data were adjusted to BMI, leptin and FLI remained significantly different in the pre-treated AN subgroup when compared with the control group.

Conclusions: Our results suggest that leptin is the most important adipokine in AN. It is also important that in our AN population leptin and FLI are the only factors that are influenced not only by the fat content.
