Background: The question of where to hospitalize extremely malnourished patients with anorexia nervosa (AN) is a real dilemma. On one hand, psychiatrists have to deal with severe medical complications that are not within their competences and that justify hospitalization in an internal medicine ward. On the other hand, medical doctors have to face psychic decompensations that would justify admission to a psychiatric ward. In this context, we share our experience of management of severely malnourished AN adult patients in a transdisciplinary specialized eating disorders (ED) unit, referral center for AN associated with somatic severity. Method: First, we described the modalities of care proposed to patients with AN hospitalized in the medical unit. Intensive medical care, both somatic and psychiatric, are provided thanks to a transdisciplinary therapeutic program, where objectives are to: medically stabilize the patient, initiate progressive refeeding and start supportive psychotherapy before being transferred to a psychiatric ED unit. Secondly, we conducted a retrospective descriptive study that included all adult patients with AN admitted for the first time to the unit, between November 1997 and January 2014, for severe malnutrition and/or complications of the ED. Objective was to specify patients’ characteristics: demographic, nutritional status, history of ED, care pathway. Results: Among a cohort of 386 adult patients with AN (21 males and 365 females) admitted for the first time in the unit, mean age was 29.4 (±11.5) years, mean BMI was 12.7 (±2.2) kg/m2. Before being supported in the unit, 78.2% of patients had already been hospitalized in other hospitals. Mean length of stay was 35.2 days. Patients were clinically serious and unstable because of life-threatening somatic complications due to a low BMI. During hospital stay, a temporary transfer to medical intensive care unit was necessary for 25.6% of patients. Average patient weight gain was 0.777 kg per week and 81.9% of patients benefited from enteral nutrition. Conclusion: This specialized transdisciplinary unit where physician nutritionists and psychiatrists coordinate medical care together, allow a better understanding and management of extreme malnutrition associated with AN. Thanks to their expertise, care teams are less critical and less rejecting towards patients. Thus, therapeutic alliance could be optimized.

BACKGROUND: Citrulline (CIT), is not extracted by the splanchnic area, can stimulate muscle protein synthesis and could potentially find clinical applications in conditions involving low amino acid (AA) intake, such as in malnourished older subjects. OBJECTIVE: Our purpose was to research the effects of CIT supplementation on protein metabolism in particular on non-oxidative leucine disposal (NOLD, primary endpoint), and splanchnic extraction of amino acids in malnourished older patients. DESIGN: This prospective randomized multicenter study determined whole-body and liver protein synthesis, splanchnic protein metabolism and appendicular skeletal muscle mass (ASMM) in 24 malnourished older patients [80-92 years; 18 women and 6 men] in inpatient rehabilitation units. All received an oral dose of 10 g of CIT or an equimolar mixture of six non-essential amino acids (NEAAs), as isonitrogenous placebo, for 3 weeks. RESULTS: NOLD and albumin fractional synthesis rates were not different between the NEAA and CIT groups. Splanchnic extraction of dietary amino acid tended to decrease (p = 0.09) in the CIT group (45.2%) compared with the NEAA group (60.3%). Total differences in AA and NEAA area under the curves between fed-state and postabsorptive-state were significantly higher in the CIT than in the NEAA group. There were no significant differences for body mass index, fat mass (FM), lean mass (LM) or ASMM in the whole population except for a tendential decrease in FM for the citrulline group (p = 0.089). Compared with Day 1, lean mass and ASMM significantly increased (respectively p = 0.016 and p = 0.018) at Day 20 in CIT-treated women (mean respective increase of 1.7 kg and 1.1 kg), and fat mass significantly decreased (p = 0.001) at Day 20 in CIT-group women (mean decrease of 1.3 kg). CONCLUSIONS: Our results demonstrate that CIT supplementation has no effect on whole-body protein synthesis or liver protein synthesis in malnourished older subjects. However, CIT supplementation was associated with a higher systemic AA availability. In the subgroup of women, CIT supplementation increased LM and ASMM, and decreased FM.

Introduction et but de l’etude L’anorexie mentale (AM) est la pathologie psychiatrique avec le plus haut taux de mortalite, notamment a cause de la denutrition. L’immunodepression cellulaire induite par cette denutrition severe pourrait etre a l’origine de l’apparition d’infections pulmonaires chroniques opportunistes (IPCO). Seuls quelques cas d’IPCO dans l’AM ont ete rapportes dans la litterature. Le but de cette etude etait d’identifier les facteurs associes aux IPCO dans une population de patients denutris atteints d’AM. Materiel et methodes Une etude observationnelle a ete realisee dans un service soins tertiaires dedie aux patients atteints d’AM et severement denutris. Le diagnostic d’IPCO a ete fait sur la presence de lesions suggestives au scanner thoracique, associe ou non a une identification microbiologique. Chaque patient avec un diagnostic d’IPCO a ete apparie sur l’âge et le sexe a deux patients non malades, hospitalises au cours de la meme periode. Les variables suivantes ont ete recueillies : poids, IMC, CRP, albuminemie, transthyretine, neutrophiles, lymphocytes, et identification des germes a la culture des expectorations le cas echeant. Le test t de Student et la regression logistique ont ete effectues pour determiner les parametres associes aux IPCO. Une analyse discriminante et des courbes de ROC ont ete realisees pour les variables significatives en univariee. Resultats et analyse statistique Entre 2004 et 2020, 1441 patients ont ete hospitalises et 31 avaient un diagnostic d’IPCO (2,2 %). Les patients atteints d’IPCO avaient un IMC inferieur (11,5 vs 13,0 ; p = 0,02), un taux de lymphocytes sanguins plus bas (763 vs 1637/mm3 ; p Conclusion L’IPCO est une des complications somatiques observees chez les patients avec AM. Cette etude observationnelle a identifie le taux de lymphocytes comme etant le principal facteur predictif d’IPCO. Des etudes prospectives sont necessaires pour confirmer ce seuil en prospectif et juger de l’utilite de realiser un scanner thoracique systematique pour ces patients.

Background The need to preserve operating room (OR) scheduling flexibility can challenge adherence to the 2-h pre-operative fasting period recommendation before elective surgery. Our primary objective was to assess the feasibility of a pre-operative carbohydrate (CHO) drink delivery strategy preserving OR scheduling flexibility. Methods During the 1st study phase, patients admitted for elective surgery fasted overnight (Control group); during the 2nd phase, patients fasted overnight and received a pre-operative CHO drink (CHO group). CHO delivery time was set to allow any patient to be ready for surgery 30 min ahead of the scheduled time and any patient with an operation scheduled in the afternoon to be ready at 13:00 hours; patients admitted the morning of an early morning operation would not be allowed to take a CHO drink. Results We included 194 patients in the Control group and 199 in the CHO group. In the CHO group, the morning CHO dose was delivered to 66.3% of the patients (95% CI 59.3–72.9%), with a median pre-operative fasting time period of 4 h 57 min. After excluding patients admitted the morning of an operation scheduled before 10:00 hours, the delivery rate was 77.2% (70.2–83.3%). Patients in the CHO group experienced significantly less pre-operative thirst (median 2 vs. 5 on a 0–10 scale, P < 0.0001) and hunger (0 vs. 2, P < 0.0001) than those in the Control group. Conclusion Although preservation of OR scheduling flexibility resulted in a longer fasting time than recommended, CHO drink can be made available to a large proportion of patients with significantly reduced perioperative discomfort.

L'infection par le VIH est une maladie aux facettes multiples. Cette infection virale chronique est, au moins a ces debuts, pauci symptomatique. Elle detruit pourtant progressivement le systeme immunitaire tout en provoquant des perturbations metaboliques aux consequences inattendues. Celles-ci vont constituer le lit de la denutrition chronique dont l'installation plus ou moins rapide dependra des conditions d'environnement du sujet infecte, jusqu'au moment ou les infections dites opportunistes, en raison de leur survenue avec l'immunodepression, vont elles-memes precipiter et rendre irreversible cette denutrition. Le controle par les anti-retroviraux de la multiplication du virus va totalement bouleverser les voies metaboliques precedemment mises a mal. Ces nouvelles perturbations vont laisser une trace visible sur la silhouette du sujet infecte alors que le developpement de l'atherosclerose semble etre promu par cette nouvelle situation metabolique. Ces differentes facettes doivent etre connues. L'extension de l'epidemie de sida a travers le monde conduira tous les praticiens quelques soit leur specialite a la rencontrer. La denutrition au premier plan des aspects nutritionnels du sida depuis 20 ans ne disparait pas. Elle reste une preoccupation majeure des pays depourvus de possibilite therapeutique et n'a pas disparu des pays occidentaux favorises. Les aspects metaboliques et nouveaux que la survie des malades fait apparaitre mettra en demeure bien des medecins de pouvoir repondre aux questions des malades.

Introduction et but de l’etude Le vieillissement est associe a la sarcopenie qui peut etre aggravee par la denutrition. Il a ete demontre que la citrulline (Cit) a la propriete de stimuler la synthese proteique musculaire et de diminuer la masse grasse chez le rat âge. Notre hypothese est que la Cit pourrait stimuler la synthese proteique musculaire et augmenter la masse musculaire chez la personne âgee denutrie, qui presente une resistance a l’anabolisme musculaire. Materiel et methodes Cette etude prospective, randomisee, multicentrique a inclus 29 patients âges denutris hospitalises en soins de suite. Ils recevaient, pendant 20 j, par voie orale, soit 10 g de Cit, soit un melange equimolaire de six acides amines non essentiels (AANE) comme placebo isoazote. La composition corporelle des patients etait evaluee par DEXA a j1 et a j20 : masse maigre totale (MM), masse maigre squelettique appendiculaire (MMSA), masse grasse (MG). Resultats Vingt-quatre patients ont termine l’etude. Les MM et MMSA etaient significativement augmentees a j20 par rapport a j1 dans le groupe Cit. La MG etait significativement diminuee dans le groupe Cit chez les femmes. Les variations de la MMSA et de la MG etaient significativement differentes entre les deux groupes chez les femmes ( Tableau 1 ). Conclusion Cette etude demontre pour la premiere fois que la Cit augmente la masse maigre et reduit la masse grasse chez des patients âges denutris hospitalises.

Introduction et but de l’etude La prise en charge nutritionnelle de la sarcopenie et de la denutrition est souvent peu efficace chez la personne âgee, notamment a cause de la resistance a l’anabolisme proteique postprandial. La citrulline stimule la synthese proteique musculaire chez le rat âge et chez l’homme jeune. Le but de cette etude etait de mesurer si la citrulline est efficace sur le turn over proteique des patients âges denutris hospitalises. Materiel et methodes Cette etude prospective (PHRC national de 2007, ClinicalTrials.gov Identifier : NCT00714675 ), randomisee et multicentrique a inclus 29 patients âges denutris hospitalises en soins de suite geriatrique. Ils recevaient tous, pendant 20 jours, par voie orale, soit 10 g de citrulline soit un melange iso-azote de 6 acides amines non essentiels. Le turn over proteique corps entier, la vitesse de synthese fractionnaire de l’albumine et la sequestration splanchnique ont ete mesures le 21e jour par une technique de dilution isotopique utilisant la (13C)-leucine et la 3D-leucine, chez des patients a jeun depuis 12 h et en situation postprandiale. Resultats Vingt-quatre patients ont termine l’etude. Il n’y a pas de modification du turn over proteique et de la synthese proteique corps entier (NOLD). La vitesse de synthese fractionnaire de l’albumine n’etait pas modifiee. En revanche, il existait une tendance a la diminution de l’extraction splanchnique des acides amines chez les patients traites par la citrulline (citrulline : 45,2 [26,2 ; 58,4] %/j, acides amines non essentiels : 60,3 [48,3 ; 69,7 %/j] p Conclusion Cette etude montre que la citrulline n’a d’effet ni sur la synthese proteique corps entier ni sur la vitesse de synthese fractionnaire de l’albumine. En revanche, elle tend a diminuer la sequestration splanchnique des acides amines et augmente leur biodisponibilite en peripherie. Ce processus etant une des cles de la synthese proteique, la citrulline pourrait etre un adjuvant nutritionnel interessant, en presence d’une prise en charge hypercalorique–hyperproteique, chez les personnes âgees denutries.
