title: Correlation between psychometric and biological parameters in anorexic and bulimic patients during and after an intensive day hospital treatment.
abstract: This study describes: 1. The therapeutic effects on anorexia nervosa (AN) and bulimia nervosa (BN) patients of a psycho-nutritional intensive day-hospital program; 2. The possible correlation between the changes observed in the psychometric tests and the variations of a number of biological parameters. Forty-six female patients (24 AN and 22 BN) were assessed through a semi-structured clinical interview based on DSM-IV criteria for Eating Disorders (ED) and a number of psychometric tests (SCL-90R, BDI, EDI-2, EAT-40, BITE, BAT) at the beginning and at the end of treatment, and after a 6-month follow-up. At these three times, we also assessed the plasma level of leptin, cortisol, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and 17beta-estradiol together with body mass index (BMI) and menstrual cycle. From beginning to discharge, the scores on all psychometric tests improved in the whole sample, except for the Perfectionism subscale of EDI-2 in both groups (AN and BN), the Anger-Hostility, Phobic Anxiety and Paranoid Ideation subscales of SCL-90 and the Interpersonal Distrust subscale of EDI-2 in the BN group. At follow-up, there was a worsening of the BITE scores and of a number of EDI-2 subscales, especially in the AN subgroup - with these changes correlating with the trend of BMI. In AN patients, plasma leptin levels changed from the beginning to the end of treatment and at follow-up according to BMI changes. The mean plasma leptin level in the BN subgroup was higher than in the AN one. We found a statistically significant correlation with the scores of BDI, SCL-90R Depression and Ineffectiveness subscales, EAT-40, BITE-Symptom subscale and the trend of menses dividing these patients into two subgroups (according to the plasma leptin concentration, higher or lower than the top leptin level in the anorexics). These data seem to confirm that leptin secretion doesn't correlate univocally to BMI.
