抜粋

Anorexia nervosa (AN) is a chronic psychiatric disorder which is characterized by patient-induced weight loss. Complications in many organ systems can be seen in AN such as cardiovascular, gastrointestinal, and endocrine system including hypothalamic-pituitary-adrenal axis, even after recovery of body weight by treatment. Urinary steroid profile analysis using gas chromatography/mass spectrometry (GC/MS) in selected ion monitoring (SIM) has been reported to be useful for the diagnosis of abnormal steroidogenesis in newborn infants, childhood, and adults. The aim of this study was to analyze the circadian variation of cortisol secretion in patients with anorexia nervosa (AN) in childhood and adolescence after recovery of body weight by treatment using GC/MS in SIM. The subjects were 7 healthy young adults (20-23 yr of age, BMI 19.7-24.8 kg/m2) and 5 AN patients in childhood and adolescence (13-19 yr of age), who had recovered body weight by treatment (BMI 15.4-19.3 kg/m2; 3rd-25th to 50th percentile). Urine samples were collected for 26 hours (from 21:00 to 23:00 next day) at each urination. In each sample, the cortisol metabolites were measured by GC/MS in SIM. The sum of all cortisol metabolites was calculated as mg/g creatinine. In all 5 AN patients in childhood and adolescence, the circadian variation of the sum of cortisol metabolites was observed and was similar to that in healthy young adults. Although our data are preliminary, in patients with AN in childhood and adolescence, who have recovered body weight by treatment, the circadian variation of cortisol secretion may be conserved.
