Position of the American Dietetic Association: Nutrition intervention in the treatment of anorexia nervosa, bulimia nervosa, and other eating disorders.

It is the position of the American Dietetic Association that nutrition intervention, including nutritional counseling, by a registered dietitian (RD) is an essential component of the team treatment of patients with anorexia nervosa, bulimia nervosa, and other eating disorders during assessment and treatment across the continuum of care. Diagnostic criteria for eating disorders provide important guidelines for identification and treatment. However, it is thought that a continuum of disordered eating may exist that ranges from persistent dieting to subthreshold conditions and then to defined eating disorders, which include anorexia nervosa, bulimia nervosa, and binge eating disorder. Understanding the complexities of eating disorders, such as influencing factors, comorbid illness, medical and psychological complications, and boundary issues, is critical in the effective treatment of eating disorders. The nature of eating disorders requires a collaborative approach by an interdisciplinary team of psychological, nutritional, and medical specialists. The RD is an integral member of the treatment team and is uniquely qualified to provide medical nutrition therapy for the normalization of eating patterns and nutritional status. RDs provide nutritional counseling, recognize clinical signs related to eating disorders, and assist with medical monitoring while cognizant of psychotherapy and pharmacotherapy that are cornerstones of eating disorder treatment. Specialized resources are available for RDs to advance their level of expertise in the field of eating disorders. Further efforts with evidenced-based research must continue for improved treatment outcomes related to eating disorders along with identification of effective primary and secondary interventions.

Temperament, character and suicide attempts in anorexia nervosa, bulimia nervosa and major depression.

OBJECTIVE: We examined the relation between personality traits as measured by the Temperament and Character Inventory (TCI) and a reported history of suicide attempts in women with anorexia nervosa, bulimia nervosa and major depression. METHOD: We compared the prevalence and severity of suicide attempts in women with anorexia nervosa (n = 68), bulimia nervosa (n = 152) and major depression with no history of an eating disorder (n = 59), and we examined the relation between the TCI scales and suicide attempts. RESULTS: Comparable numbers of women across the three groups had attempted suicide. The temperament dimension of high persistence and the character dimensions of low self-directedness and high self-transcendence were associated with a reported history of suicide attempts. CONCLUSION: Suicide attempts are equally common in women with eating disorders and women with depression. Whether the observed association between temperament and suicide attempts reflects correlates, causal factors or sequelae of suicide attempts is unknown.

A case of comorbid anorexia nervosa, bulimia nervosa, and Munchausen's syndrome.

Reports of comorbid eating disorders and Munchausen's syndrome are rare. As part of a follow-up study of the outcome of anorexia nervosa, medical records and direct structured psychiatric interview data were collected on all women treated for anorexia nervosa in Christchurch, New Zealand between 1981-1984. On interview, one participant received diagnoses of anorexia nervosa, bulimia nervosa, and factitious disorder (Munchausen's syndrome). The subject interwove symptoms of her eating disorders with factitious presentations on several occasions. This diagnosis had not been apparent prior to compilation of all medical records.

Position of the American Dietetic Association: nutrition intervention in the treatment of anorexia nervosa, bulimia nervosa, and eating disorders not otherwise specified (EDNOS).

More than 5 million Americans suffer from eating disorders. Five percent of females and 1% of males have anorexia nervosa, bulimia nervosa, or binge eating disorder. It is estimated that 85% of eating disorders have their onset during the adolescent age period. Although Eating Disorders fall under the category of psychiatric diagnoses, there are a number of nutritional and medical problems and issues that require the expertise of a registered dietitian. Because of the complex biopsychosocial aspects of eating disorders, the optimal assessment and ongoing management of these conditions appears to be with an interdisciplinary team consisting of professionals from medical, nursing, nutritional, and mental health disciplines (1). Medical Nutrition Therapy provided by a registered dietitian trained in the area of eating disorders plays a significant role in the treatment and management of eating disorders. The registered dietitian, however, must understand the complexities of eating disorders such as comorbid illness, medical and psychological complications, and boundary issues. The registered dietitian needs to be aware of the specific populations at risk for eating disorders and the special considerations when dealing with these individuals.

Psychopharmacotherapy of anorexia nervosa, bulimia nervosa and binge-eating disorder.

Pharmacotherapy for anorexia nervosa is considered to be of limited efficacy. However, many studies suffer methodological limitations, and the utility of newer drugs in the treatment of anorexia has not been examined yet. Although there have been more fruitful investigations on the efficacy of medication in the management of bulimia nervosa, there are still many unresolved issues regarding the optimal management of partial remission during the acute treatment phase and the intensity and duration of pharmacotherapy to achieve optimal prophylaxis. Selective serotonin reuptake inhibitors (SSRIs) control the binge urges in binge-eating disorder, but more trials are required to investigate the utility of SSRIs and other agents in maintenance treatment. We review the current status of psychopharmacotherapy for anorexia nervosa, bulimia nervosa and binge-eating disorder and evaluate the merits of newer agents in the treatment of these disorders.

Serum leptin concentrations in patients with anorexia nervosa, bulimia nervosa and non-specific eating disorders correlate with the body mass index but are independent of the respective disease.

OBJECTIVE: Leptin, the product of the ob gene, is a recently discovered hormone secreted by adipocytes. Serum leptin concentrations increase in correlation with the percentage of body fat, but little else is known about the physiological actions of leptin in humans. The aim of this study was to determine the role of leptin in severe eating disorders, and whether its levels are correlated with the specific disease or exclusively with body weight. TESTS: Serum concentrations of human leptin were analysed by specific radioimmunoassay and compared with the individual body mass indexes (BMI). The correlations between serum leptin concentrations and BMI, age and height were analysed. PATIENTS: A total of 65 women were studied: 25 patients with anorexia nervosa, 20 women with bulimia nervosa, 6 women with a diagnosis of nonspecific eating disorder, and 14 normal-weight women who acted as controls. At the time of the study, the patients were non-cured, under treatment, and at different stages of therapeutic evolution. MEASUREMENTS: Plasma leptin levels were measured by specific radioimmunoassay. RESULTS: The mean serum leptin in the normal-weight women was 10.5 +/- 1.1 micrograms/l, compared with 7.6 +/- 1.1 micrograms/l in the anorexia nervosa patients (P < 0.05). This reduction in leptin levels was paralleled by the differences in BMI (21.4 +/- 0.4 vs 18.8 +/- 0.2) P < 0.05. These differences between the controls and anorexia nervosa patients were not observed in patients with bulimia nervosa who had a mean serum leptin level of 9.9 +/- 1.4 micrograms/l and BMI of 21.3 +/- 0.6, neither significantly different from controls. On the contrary, patients with non-specific eating disorders showed a large reduction in BMI (17.9 +/- 1.2, P < 0.05 vs control), and a parallel reduction in serum leptin levels, 4.5 +/- 1.0 (P < 0.05 vs controls). When individual values of leptin were plotted against BMI a wide range was observed in all groups; in the control subjects from 5.6 to 17.7 micrograms/l, in anorexia nervosa patients from 2.1 to 28.1 micrograms/l, in patients with bulimia nervosa between 2.6 and 25.9 micrograms/l, and in women with non-specific eating disorder from 2.0 to 8.9. No correlation was observed with the specific disease but in each group a significant correlation was observed only with BMI. CONCLUSIONS: Serum leptin levels in three groups of patients affected by severe eating disorders are not related to the specific pathology but are correlated with the individual BMI. The analysis of leptin values may be a useful index of assessing the adipose tissue stores in the clinical setting, but will be of no help for diagnosis nor prognosis of severe eating disorders.

Full syndromal versus subthreshold anorexia nervosa, bulimia nervosa, and binge eating disorder: a multicenter study.

OBJECTIVE: The diagnostic criteria for anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED) establish symptom severity levels, which are used to separate full cases from partial cases. However, the value of these distinctions is unclear. METHOD: Three hundred eighty-five women with full or partial AN, BN, or BED were assessed at entry into a longitudinal study of eating disorders. RESULTS: Stepwise discriminant analysis revealed that full and partial BN were discriminated by the Yale-Brown-Cornell Eating Disorders Scale total scores (kappa =.46). However, it was not possible to discriminate between full and partial AN or BED. Discriminant analysis also demonstrated clear differences between full AN, BN, and BED. DISCUSSION: Full BN can be differentiated from partial BN by more severe eating disorder symptoms, whereas both full and partial AN and full and partial BED appear quite similar. These results emphasize the distinct nature of AN, BN, and BED, as well as the similarities between full and partial cases.

Fractures in patients with anorexia nervosa, bulimia nervosa, and other eating disorders--a nationwide register study.

OBJECTIVE: To study fracture risk in patients with anorexia nervosa (AN), bulimia nervosa (BN), or eating disorders not otherwise specified (EDNOS). METHOD: Cohort study including all Danes diagnosed with AN (n = 2,149), BN (n = 1,294), or EDNOS (n = 942) between 1977 and 1998. Each patient was compared with three randomly drawn age- and gender-matched control subjects. RESULTS: Fracture risk was increased in AN after diagnosis compared to controls (incidence rate ratio: 1.98, 95% CI: 1.60-2.44), but not before. The increased fracture risk persisted more than 10 years after diagnosis. A significant increase in fracture risk was found before diagnosis in BN (1.31, 95% CI: 1.04-1.64), with a trend towards an increase after diagnosis (1.44, 95% CI: 0.93-2.22). EDNOS patients had a significant increase in fracture risk before (1.39, 95% CI: 1.06-1.81) and after diagnosis (1.77, 95% CI: 1.25-2.51). DISCUSSION: The increased fracture risk many years after diagnosis indicates permanent skeletal damage.

Anorexia nervosa, bulimia nervosa: causal theories and treatment.

Anorexia nervosa and bulimia nervosa are eating disorders characterized by gross disturbances in eating behavior. Recently these disorders have reached near-epidemic proportions, affecting approximately 1.2 million adolescent and young adult females in the United States. The incidence in males is considerably less, and the prevalence rate has remained fixed at 5 percent during the last five years. The estimates of mortality range between 1 and 15 percent and are equally divided between medical complications (electrolyte disturbance, acute kidney failure, cardiac complications) and suicide. Successful treatment requires a combination of aggressive medical management, psychotherapy, behavioral management, food-intake management and nutritional counseling. This requires health care providers to understand 1) the psychological ramifications of these disorders, 2) the types of depression associated with them, 3) antidepressants used and therapeutic dosages, 4) correction of nutritional deficiencies, 5) outpatient management and 6) indications for hospitalization (inpatient management).

Serum salivary isoamylase levels in patients with anorexia nervosa, bulimia or bulimia nervosa.

Salivary isoamylase levels were studied in a sample of 35 women with bulimia, anorexia nervosa, or bulimia nervosa. Salivary isoamylase elevation was related to the presence of sham eating, evidenced by elevated isoamylase values in patients with bulimia nervosa or bulimia, and depressed isoamylase values in patients with anorexia nervosa. Salivary isoamylase levels may provide insight and have bearing on the functional interrelationship between appetite regulation and ingestive behavior in patients with eating disorders, as abnormalities may occur during both the cephalic as well as the oral phase of eating.

Clinical, psychopathological and personality correlates of interoceptive awareness in anorexia nervosa, bulimia nervosa and obesity.

OBJECTIVE: To determine the levels of interoceptive awareness (IA), which measures the ability of an individual to discriminate between sensations and feelings, and between the sensations of hunger and satiety, in eating disorder patients and to identify the clinical, psychopathological and personal variables correlated with IA. SAMPLING AND METHODS: Sixty-one restrictor anorectics, 61 binge-purging anorectics, 104 purging bulimics, 49 obese subjects with binge eating disorder (BED) and 47 obese subjects without BED were compared. They were assessed with the Eating Disorder Inventory-2, the Temperament and Character Inventory, and the Beck Depression Inventory, and their clinical and sociodemographic features were recorded. RESULTS: In all patients, the levels of IA were higher than the 'normal' ones; in bulimia nervosa, they were higher than in anorexia nervosa and obesity. Similar personal features and eating attitudes are shared by patients with bulimia nervosa and BED. In the total sample, the following variables independently correlate with IA: the Beck Depression Inventory, self- directedness and persistence. CONCLUSIONS: The importance of an altered IA in eating disorders is supported. Both depression and a perfectionist and poorly self-directive personality can lead to greater difficulties in discriminating hunger and satiety.

A polysomnographic study in young psychiatric inpatients: major depression, anorexia nervosa, bulimia nervosa.

The baseline EEG sleep patterns of 10 young depressed patients, 20 patients with anorexia nervosa, 10 patients with bulimia nervosa, and 10 healthy subjects were found to be indistinguishable, except for an increased REM density in the depressed patients. In eating disorder patients, a concomitant major depressive episode had no influence on EEG sleep. The results of the cholinergic REM sleep induction test revealed a significantly faster induction of REM sleep in the depressed patients when compared with the eating disorder patients and the control subjects. This indicates a subthreshold hypersensitivity of the REM sleep triggering cholinergic transmitter system in depressives, but not in eating disorder patients.

Cytokine production in patients with anorexia nervosa, bulimia nervosa, and obesity.

OBJECTIVE: We previously reported elevated serum levels of the cytokines interleukin-6 (IL-6) and transforming growth factor-beta (TGF-beta) in patients with anorexia nervosa (AN). We investigated the cellular production of these two cytokines and of interferon-gamma (IFN-gamma), interleukin-1alpha (IL-1alpha), and tumor necrosis factor-alpha (TNF-alpha) in subjects with AN, bulimia nervosa (BN), and obesity as well as in normal-weight control subjects. METHODS: Supernatant fluids from isolated peripheral blood mononuclear cells (PBMC) incubated with and without concanavalin A (ConA) were assayed for cytokine concentrations by enzyme-linked immunosorbent assay (ELISA). RESULTS: Significant differences across the four groups were found in the stimulated cellular production of IFN-gamma and IL-6. Stimulated IFN-gamma production was elevated in the AN group compared to controls. IL-6 production was significantly elevated in obese subjects relative to the two normal-weight groups, BN and controls, and tended to be higher in the AN group than in the controls, but not significantly so. IL-1alpha production was greater in obese subjects. CONCLUSION: The findings of increased IFN-gamma production and a tendency toward increased IL-6 production (both of which suppress food intake in animals) in individuals who severely restrict food intake suggest a potential role for these cytokines in the pathogenesis of AN. Elevated IL-6 and IL-1alpha production by PBMC in obese individuals requires further investigation to determine if these cytokines contribute to the development or perpetuation of obesity.

Average total energy expenditure in anorexia nervosa, bulimia nervosa, and healthy young women.

The double-labeled water method was used to measure average daily total energy expenditure (EE) in 11 healthy normal-weight women classified as unrestrained eaters, in 8 patients with anorexia nervosa, and in 8 patients with bulimia nervosa. The body mass index was 20.0 +/- 1.3 kg/m2 in the control group, 15.2 +/- 5.6 kg/m2 in the anorectic groups, and 19.7 +/- 1.9 kg/m2 in the bulimic group. EE was measured over a 2-week period during which weight remained constant in all groups and was 2357 +/- 504 kcal/day for the controls, 2510 +/- 920 kcal/day for the bulimics, and 2899 +/- 656 kcal/day for the anorectics. Differences were not significant among groups. Physical activity was recorded in diaries by all subjects. Anorectic patients showed significantly more activity than all other groups. The data suggest that EE is high in anorectic patients as a consequence of physical activity.

Circulating leptin in patients with anorexia nervosa, bulimia nervosa or binge-eating disorder: relationship to body weight, eating patterns, psychopathology and endocrine changes.

A decreased production of leptin has been reported in women with anorexia nervosa (AN) and has been attributed merely to the patients' reduced body fat mass. The extent to which eating patterns, purging behaviors, psychopathology and endocrine changes may contribute to the genesis of leptin alterations has not been deeply investigated. Therefore, we measured plasma levels of leptin, glucose and other hormones in three groups of eating disorder patients with different body weight (BW), eating patterns and purging behaviors. Sixty-seven women, 21 with AN, 32 with bulimia nervosa (BN), 14 with binge-eating disorder (BED) and 25 healthy females volunteered for the study. We found that circulating leptin was significantly reduced in AN and BN patients, but significantly enhanced in women with BED. In anorexics, plasma glucose was decreased, whereas plasma cortisol was enhanced; blood concentrations of 17beta-estradiol and prolactin (PRL) were reduced in both AN, BN and BED patients. In all subject groups, a strong positive correlation emerged between plasma levels of leptin and the subjects' BW or body mass index, but not between leptin and psychopathological measures, plasma glucose, cortisol, PRL and 17beta-estradiol. Since leptin was reduced in both underweight anorexics and normal weight bulimics, but increased in overweight BED women, who compulsively binge without engaging in compensatory behaviors, we suggest that factors other than BW may play a role in the determination of leptin changes in eating disorders.

No evidence for involvement of the leptin gene in anorexia nervosa, bulimia nervosa, underweight or early onset extreme obesity: identification of two novel mutations in the coding sequence and a novel polymorphism in the leptin gene linked upstream region.

Mutations in the leptin gene can result in profound obesity in both rodents and humans. In humans, serum leptin levels correlate with body mass index (BMI: kg m(-2)). However, in patients with anorexia nervosa (AN) leptin levels are lower than in BMI-matched healthy controls. We had previously argued that genes involved in weight regulation should be considered as candidate genes for AN. To investigate this hypothesis we screened the coding region of the leptin gene and part of the leptin gene linked upstream region (LEGLUR) in 49 patients with AN and 315 children and adolescents with extreme obesity. Two novel mutations in the coding region (Ser-91-Ser; Glu-126-Gln), each found in a single proband, and a novel polymorphism in the LEGLUR (position -1387 G/A; frequency of both alleles approximately 0.50) were identified. Tests for association of LEGLUR polymorphism alleles were negative by comparing allele frequencies between 115 AN patients, 71 bulimia nervosa patients, 315 extremely obese children and adolescents, 141 healthy underweights and 50 controls that were not selected for body weight. Tests for transmission disequilibrium were also negative. Hence, an influence of variations in the leptin gene on eating disorders or extreme early onset obesity could not be detected.

Post-surgical refusal to eat: anorexia nervosa, bulimia nervosa or a new eating disorder? A case series.

Speculation concerning the role of psychiatric disorders in patients undergoing bariatric surgery is abundant in the literature. Psychiatric factors predicting the success or failure of bariatric surgery have not been adequately described. However, an increasing number of cases of eating disorders in the postoperative period are being reported. A concise literature review and 5 cases are presented with the purpose of studying the specific pathological eating habits of these patients. The criteria for Anorexia or Bulimia Nervosa were not fulfilled in most of the reports studied and were not met by the 5 patients described. The criteria for a new eating disorder (Post-Surgical Eating Avoidance Disorder, PSEAD) are proposed.
