“…It is a multicausal disorder, resulting from complex interactions between psychosocial and biological factors. Above all, it affects young women, generally without other diseases [1]. Thus, anorexia nervosa is a good model to study the effects of malnutrition on the respiratory system, since it excludes the consequences that some chronic diseases can have on the lung.…”

Background: Anorexia nervosa is a good model to study the effects of malnutrition on the respiratory system, since it excludes the consequences that some chronic diseases can have on the lung. Objective: The objective of this study was to assess pulmonary function and alterations in the respiratory system in patients with anorexia nervosa. Methods: Twenty-two women, 12 with anorexia nervosa and 10 healthy volunteers, were studied. Anthropometric data were gathered for all the participants. In every case, an arterial blood gas test and functional respiratory study, that included spirometry, plethysmography, measure of maximum muscular respiratory pressure and study of the ventilatory pattern at baseline and after hypercapnic stimulation, were performed. Results: No significant differences were found in mean age and height in both groups of patients but there was a difference in body mass index (p < 0.05). In pulmonary function tests, an increase in residual volume (RV), RV/total lung capacity (TLC) ratio and functional residual capacity and a decrease in maximum respiratory pressure were found in patients with anorexia nervosa compared to the control group (p < 0.05). Differences were also found in the ventilatory pattern, with a reduction in minute ventilation and occlusion pressure as well as a decreased response of these parameters to hypercapnic stimulation (p < 0.05) in the patients with anorexia nervosa. Conclusion: In patients with anorexia nervosa, a significant elevation in RV, in the RV/TLC ratio and in functional residual capacity and a decrease in the maximum respiratory pressure were noted. In addition, they present an alteration in the central respiratory drive and a response of the respiratory system to hypercapnic stimulation. Although these alterations have no repercussion on the maintenance of gas exchange in baseline conditions, they may have in extreme situations.

Objective: Our aim was to examine the relationship between resting energy expenditure (REE) and circulating leptin levels during long-term refeeding in adolescent girls with anorexia nervosa (AN). Method: We measured REE, the plasma leptin level, the free T 3 level, body surface area (BSA), and dietary energy intake in AN adolescents before and 8 weeks after refeeding therapy. Results: All parameters in AN subjects before the refeeding therapy were significantly lower than those in AN subjects after the therapy and in the controls. There were no significant differences in REE and BSA between posttherapy AN subjects and controls, but plasma leptin levels in the posttherapy AN subjects were still significantly lower than those in the controls. Significant correlations between REE and BSA were detected in the AN subjects both before and after the refeeding therapy, but REE did not correlate significantly with plasma leptin level in either of the AN groups. Discussion: Our results suggest that the REE in AN subjects after long-term refeeding therapy is not associated with the changes in plasma leptin levels but with BSA.
