BACKGROUND Serotonin (5-HT) pathway abnormalities were demonstrated in anorexia nervosa (AN). Brain imaging studies on 5-HT receptors support this evidence. 4-(2-methoxyphenyl)-1-[2-(N-2-pyridinyl)-p-fluorobenzamido]-ethylpiperazine ([(18)F]MPPF) is a selective 5-HT(1A) receptor antagonist with an affinity close to that of endogenous 5-HT. METHODS In 24 subjects including 8 lean restrictive-type AN patients, 9 recovered from restrictive-type AN subjects and 7 age-matched control subjects, we assessed in vivo brain [(18)F]MPPF binding by positron emission tomography and eating-related psychopathological traits. Inter-groups differences in [(18)F]MPPF binding were evaluated by voxel-based analyses. RESULTS Restrictive AN patients presented increased [(18)F]MPPF binding in a selective area of the right cortex including part of the superior temporal gyrus, inferior frontal gyrus, parietal operculum, and temporoparietal junction. Striking regional similarities of increased [(18)F]MPPF binding were found in recovered from AN subjects. Most of the psychiatric scores were increased in restrictive AN patients, and elevated perfectionism and interpersonal distrust scores were noticed in subjects recovered from AN. CONCLUSIONS The persistent increased 5-HT(1A) receptor binding in frontotemporal region of recovered AN concomitantly with specific psychopathological traits support the hypothesis of an organic dysfunction of this area and corroborates with previous literature reports of AN cases induced by temporal lesions.

Objective: The adaptive mechanisms in response to excess energy supply are still poorly known in humans. Our aims were to define metabolic responses and changes in gene expression in skeletal muscle of healthy volunteers during fat overfeeding.

Resume Objectif L’anorexie mentale (AM) est un trouble du comportement alimentaire associant une denutrition, une amenorrhee et un trouble de l’image corporelle selon les criteres du DSM-IV. Peu d’etudes de suivi ont ete publiees. Nous avons realise une etude retrospective, portant sur la population de patientes anorexiques mentales restrictives ayant ete prises en charge de 1979 a 2004. Methodes Les donnees necessaires, elaborees a partir de l’inventaire de Morgan et Russell, ont ete recueillies entre mai et juillet 2004 a l’aide du dossier clinique et d’une enquete telephonique. Pour chaque patiente, ont ete notes la chronologie de la maladie, les caracteristiques morphologiques, le type de l’anorexie, le mode de prise en charge, l’histoire gynecologique et la situation professionnelle et conjugale. Resultats La population etudiee representait 206 patientes pour lesquelles la duree moyenne de suivi a ete de 8,3 ± 5,3 ans ; 55,8 % ont ete gueries sur les criteres IMC > 17,5 kg/m2 maintenu pendant 1 an et reprise de l’activite genitale ; 18,5 % sont entrees dans une forme chronique de la maladie et 25,7 % avaient encore une des deux composantes citees ci-dessus. Le taux de mortalite a ete de 1,8 %. En termes d’evolution de la maladie, l’âge de debut precoce lors de l’adolescence etait de bon pronostic. Par contre, l’intensite de la maigreur, un delai de prise en charge long, une frequence faible de consultation semblaient predictifs d’une issue defavorable. Conclusions La gravite de cette maladie est plutot liee a ses formes chronicisees qu’au nombre de deces qui lui sont directement imputables. Par contre, le versant psychopathologique n’a pas ete pris en compte et il semble important a evaluer puisque certains traits de personnalite sous-jacents apparaissent comme des facteurs de comorbidite.
