Abstract

It has been indicated that disturbances in the production of certain pro-inflammatory cytokines might contribute to the development of osteoporosis in girls with anorexia nervosa (AN). The aim of the study was to determine whether girls with AN exhibited a relationship between IL-1β, IL-6, TNF-α, bone turnover markers (OC and CTx), OPG, sRANKL, and the OPG/sRANKL ratio. Serum IL-1β, IL-6, TNF-α, OC, CTx, OPG, and sRANKL were determined by ELISA in 59 girls with AN and in 17 healthy counterparts, aged 13 to 17 years. Girls with AN showed significant reduction in body weight, BMI, BMI-SDS, and Cole index compared to the controls. These changes were associated with a significant increase in IL-1β, IL-6, TNF-α, OPG, and sRANKL concentrations and a decrease in bone markers and the OPG/sRANKL ratio. Significant negative correlations were found between BMI, the Cole index and CTx, OPG (girls with AN); between BMI and OC, CTx as well as the Cole index and CTx (the control group - C); between BMI, the Cole index and IL-β1, IL-6, TNF-α, CTx in all study participants (group AN+C). The combined group AN+C also exhibited positive correlation between BMI, the Cole index, and the OPG/sRANKL ratio. Girls with AN showed positive correlations be...Continue Reading
