“…However eating orders in general lead to changes in electrolyte content and associated whole-body organ dysfunction including the heart. Hypotension and sinus bradycardia is common in AN [9]. This probably results from elevated parasympathetic tone, which occur to compensate for the starvation activity along with reduced metabolic expenditure.…”

“…Moreover, repolarisation abnormalities and prolongation of ECG Q-T interval are thought to be associated with ventricular arrhythmia and severe weight loss [26,32]. However, a number of studies of HRV have confirmed that these structural and functional abnormalities of the cardiovascular system provoked by AN are reversible after weight restoration [9,25,28,29,33]. This study indicated that HRV in ED patients is lower than control, especially HRV complexity measured by Sample Entropy.…”

“…Impaired ANS control of heart rate may be a consequence of an adaptation to oxidative stress and inflammation; both present in EDs [9,10] and can be explored using heart rate variability (HRV) analysis. Linear and nonlinear HRV features describe different characteristics of ANS influence on the heart [11,12].…”

“…No obstante, dado que en la anorexia nerviosa se han descrito innumerables carencias nutricionales, en dicha situación podrían necesitarse. Así ocurre con el calcio ante el rechazo de los lácteos 36 , el hierro en pacientes vegetarianos y/o con excesivo ejercicio 54,55 , el zinc si hay escasa ingesta de carne y/o ejercicio excesivo 56,57 , la tiamina y el ácido fólico si existe abuso de alcohol 58,59 y la vitamina D si hay rechazo de lácteos y/o baja exposición solar 60 . En relación con los déficits de tiamina se han recogido complicaciones como el síndrome de Wernicke 61 .…”

Review of nutritional and dietary management of anorexia nervosaFax: +34954278167 E-mail: ijl@tcasevilla.com L a anorexia nerviosa es un trastorno habitualmente de curso prolongado, con manifestaciones psicofísicas diversas 1 . Un porcentaje de pacientes puede morir, por suicidio o complicaciones físicas, siendo frecuente la muerte súbita por cardioarritmias 1-3 , que no guarda relación con la duración de la enfermedad o la edad, pero sí con un índice de masa corporal (IMC) < 12 y niveles muy bajos de albúmina sérica 4 , aunque el riesgo de dicho desenlace es poco predecible, dada la variable respuesta individual a la desnutrición y la influencia de otros factores 5,6 . En las complicaciones influyen el bajo peso, atracones, conductas purgativas, ejercicio extenuante y autolesiones 4 , siendo reversibles con una adecuada recuperación ponderal 7 . La prevalencia del trastorno es 0,2-0,5% 8 , afectando más a las mujeres 9 , pero con iguales efectos en los varones 10 . Aún sin demostrar que la ratio mujeres-hombres esté cambiando, lo que sí ha aumentado es el rango de edad de aparición, considerando que el rango tradicional de afectación era de 15 a 24 años para la mayoría de los casos 1 .La morbi-mortalidad asociada y la compleja naturaleza del trastorno, implican un tratamiento interdisciplinar 11 , muchas veces intensivo 12 , siendo los dietistas-nutricionistas los mejor cualificados para manejar aspectos dietético-nutricionales 13 , como el restablecimiento ponderal, el logro de una ingesta que cubra los requerimientos y una adecuada educación nutricional 4 .El objetivo del trabajo fue revisar los aspectos dietético-nutricionales del tratamiento de la anorexia nerviosa, enfatizando las tareas y estándares necesarios a proporcionar por parte de los dietistas-nutricionistas en el contexto de un equipo interdisciplinar y en diferentes ámbitos: ambulatorio, hospitalario y de hospitalización parcial (unidades de día).

Objective: The objective was to determine changes in heart rate variability (HRV) in response to orthostatic challenge in a convenience sample of patients with anorexia nervosa compared to age-matched controls. A decrease in HRV has been shown to correlate with an increased risk of heart attack in coronary artery disease and heart failure patients. Method:Clinical data and ECG recordings were collected from 37 patients with eating disorders of which 16 had a diagnosis of anorexia nervosa and 42 controls. HRV was analyzed using linear and nonlinear methods during rest and orthostatic challenge from sitting to standing.Results: Significant sympathovagal changes were identified in the anorexia nervosa group, especially with nonlinear HRV parameters and orthostatic challenge. Sample entropy, a nonlinear measure provided the best discrimination between the two groups on standing (1.58 ± 0.42 vs. 1.19 ± 0.4; p<0.0001) and when the change in HRV was measured from sitting to standing (-0.06 ± 0.36 vs. -0.42 ± 0.34; p<0.0001). The anorexia nervosa group had a significantly larger response to orthostatic challenge compared to the control group suggesting sympathetic dysfunction. Discussion: Including nonlinear measures and orthostatic challenge from an ECG recording of anorexia nervosa patients at initial clinical assessment on admission to hospital provides a noninvasive, sensitive tool to determine loss of normal physiological autonomic control of heart rate that may be related to an increased risk of arrhythmic events that requires further monitoring. Conclusion:Nonlinear HRV measures are more sensitive in identifying sympathetic and parasympathetic changes associated with orthostatic challenge in patients with anorexia nervosa.
