  1. Clinical utility of subtyping binge eating disorder by history of anorexia or bulimia nervosa in a treatment sample. (United States)

    Utzinger, Linsey M; Mitchell, James E; Cao, Li; Crosby, Ross D; Crow, Scott J; Wonderlich, Stephen A; Peterson, Carol B


    This study examined whether having a history of anorexia nervosa (AN) or bulimia nervosa (BN) is associated with response to treatment in adults with binge eating disorder (BED). Data from 189 adults diagnosed with BED who were randomly assigned to one of three group cognitive-behavioral (CBT) treatments were analyzed to compare those with and without a history of AN/BN. A total of 16% of the sample had a history of AN/BN. The BED subgroup with a history of AN/BN presented with higher rates of mood disorders and greater eating-related symptom severity at baseline. Participants with a history of AN/BN also had higher global eating disorder (ED) symptoms at end of treatment (EOT), and more frequent objective binge-eating episodes at EOT and 12-month follow-up. These findings suggest that in adults with BED, a history of AN/BN is predictive of greater eating-related symptom severity following group-based CBT and poorer short- and long-term binge-eating outcomes. These findings suggest that considering ED history in the treatment of adults with BED may be clinically useful. © 2015 Wiley Periodicals, Inc.

    Pisetsky, Emily M; Thornton, Laura M; Lichtenstein, Paul; Pedersen, Nancy L; Bulik, Cynthia M


    We evaluated whether the prevalence of lifetime suicide attempts/completions was higher in women with a lifetime history of an eating disorder than in women with no eating disorder and assessed whether eating disorder features, comorbid psychopathology, and personality characteristics were associated with suicide attempts in women with anorexia nervosa, restricting subtype (ANR), anorexia nervosa, binge-purge subtype (ANBP), lifetime history of both anorexia nervosa and bulimia nervosa (ANBN), bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD). Participants were part of the Swedish Twin study of Adults: Genes and Environment (N = 13,035) cohort. Lifetime suicide attempts were identified using diagnoses from the Swedish National Patient and Cause of Death Registers. General linear models were applied to evaluate whether eating disorder category (ANR, ANBP, ANBN, BN, BED, PD, or no eating disorder [no ED]) was associated with suicide attempts and to identify factors associated with suicide attempts. Relative to women with no ED, lifetime suicide attempts were significantly more common in women with all types of eating disorder. None of the eating disorder features or personality variables was significantly associated with suicide attempts. In the ANBP and ANBN groups, the prevalence of comorbid psychiatric conditions was higher in individuals with than without a lifetime suicide attempt. The odds of suicide were highest in presentations that included purging behavior (ANBN, ANBN, BN, and PD), but were elevated in all eating disorders. To improve outcomes and decrease mortality, it is critical to be vigilant for suicide and identify indices for those who are at greatest risk.

    Fetissov, Sergueï O.; Hallman, Jarmila; Oreland, Lars; af Klinteberg, Britt; Grenbäck, Eva; Hulting, Anna-Lena; Hökfelt, Tomas


    The hypothalamic arcuate nucleus is involved in the control of energy intake and expenditure and may participate in the pathogenesis of eating disorders such as anorexia nervosa (AN) and bulimia nervosa (BN). Two systems are of particular interest in this respect, synthesizing α-melanocyte-stimulating hormone (α-MSH) and synthesizing neuropeptide Y, respectively. We report here that 42 of 57 (74%) AN and/or BN patients studied had in their plasma Abs that bind to melanotropes and/or corticotropes in the rat pituitary. Among these sera, 8 were found to bind selectively to α-MSH-positive neurons and their hypothalamic and extrahypothalamic projections as revealed with immunostaining on rat brain sections. Adsorption of these sera with α-MSH peptide abolished this immunostaining. In the pituitary, the immunostaining was blocked by adsorption with α-MSH or adrenocorticotropic hormone. Additionally, 3 AN/BN sera bound to luteinizing hormone-releasing hormone (LHRH)-positive terminals in the rat median eminence, but only 2 of them were adsorbed with LHRH. In the control subjects, 2 of 13 sera (16%) displayed similar to AN/BN staining. These data provide evidence that a significant subpopulation of AN/BN patients have autoantibodies that bind to α-MSH or adrenocorticotropic hormone, a finding pointing also to involvement of the stress axis. It remains to be established whether these Abs interfere with normal signal transduction in the brain melanocortin circuitry/LHRH system and/or in other central and peripheral sites relevant to food intake regulation, to what extent such effects are related to and/or could be involved in the pathophysiology or clinical presentation of AN/BN, and to what extent increased stress is an important factor for production of these autoantibodies.

    Full Text Available Background: Alexithymia is associated to Eating Disorders (ED and relevant for their prognosis but it is uncertain if it is ubiquitous, primary and necessary for ED outburst. Methods: 124 ED outpatients and 80 healthy controls were compared with the Toronto Alexithymia Scale, personality and psychopathology measures. Alexithymia and the other features are compared between anorexia nervosa (AN, bulimia nervosa (BN and control groups. Alexithymia-based clusters were explored and compared with controls. Alexithymia traits are correlated with the other features. Results: Difficulty in identifying feelings was ubiquitous in ED subjects. A Non-Alexithymic Cluster (NAC and an Alexithymic Cluster (ALC were found with no difference in AN/BN distribution. ALC displays disordered personality and high psychopathology. Self-directiveness and interoceptive awareness were independently related to alexithymia and to depressive feelings. These two features along with depressive features completely accounted for alexithymia variance. Conclusion: even though the difficulty in identifying feelings is ubiquitous in ED subjects, Alexithymia may not represent a primary trait but a complex dysfunction consequent to co-occurring character immaturity, altered interoceptive awareness, and depressive traits.

    Easter, Abigail; Naumann, Ulrike; Northstone, Kate; Schmidt, Ulrike; Treasure, Janet; Micali, Nadia


    To investigate dietary patterns and nutritional intake in children of mothers with eating disorders. Mothers (N = 9423) from a longitudinal general population birth cohort study, the Avon Longitudinal Study of Parents and Children, completed Food Frequency Questionnaires on their children at 3, 4, 7, and 9 years of age. Macronutrient intake was estimated, and dietary patterns were obtained using principal components analysis. Linear regression and mixed-effects models were used to assess dietary patterns and nutritional intake among children of women with lifetime anorexia nervosa (AN, n = 140), bulimia nervosa (BN, n = 170), or AN+BN (n = 71), compared with children of women without eating disorders (unexposed women, n = 9037). Children in the maternal AN and BN groups had higher scores on the "health conscious/vegetarian" dietary pattern compared with unexposed children. Less adherence to the "traditional" dietary pattern was observed in children of exposed mothers, with more pronounced differences in early childhood. Children of women with AN and BN had higher intake of energy and children of women with BN had higher intake of carbohydrates and starch and lower intake of fat, compared with children in the unexposed group. Maternal eating disorders are associated with altered offspring dietary patterns and macronutrient intake. Longitudinal changes in patterns of diet in children of women with eating disorders may increase the risk of weight gain or disordered eating later in life. Copyright © 2013 Mosby, Inc.

  6. Eating disorder symptomatology among ballet dancers. (United States)

    Ringham, Rebecca; Klump, Kelly; Kaye, Walter; Stone, David; Libman, Steven; Stowe, Susan; Marcus, Marsha


    The current study sought to compare eating disorder symptomatology among ballet dancers and individuals with restricting anorexia nervosa (RAN), bulimia nervosa (BN), and no eating pathology. Twenty-nine female ballet dancers completed assessments and were compared with an archival dataset of 26 women with RAN, 47 women with BN, and 44 women with no eating pathology. Eating disorder diagnoses and behaviors were assessed with a semi-structured clinical interview, the Eating Disorder Inventory (EDI), and a weight history interview. Eighty-three percent of dancers met lifetime criteria for AN (6.9%), BN (10.3%), AN+BN (10.3%), or EDNOS (55.0%). Moreover, dancers looked more similar to eating-disordered individuals than to control individuals on measures of eating pathology. Despite previous emphasis on the pathology AN, the current findings suggest that dancers frequently engage in binge eating and purging behaviors. Moreover, it appears that their pathology is as severe as that of non-dancing women with eating disorders. Copyright (c) 2006 by Wiley Periodicals, Inc.

    The objective of the study was to determine whether levels of biochemical and haematological parameters in patients with eating disorders (EDs) varied from the general population. Whilst dietary restrictions can lead to nutritional deficiencies, specific abnormalities may be relevant to the diagnosis, pathogenesis and treatment of EDs. With ethics approval and informed consent, a retrospective chart audit was conducted of 113 patients with EDs at a general practice in Brisbane, Australia. This was analysed first as a total group (TG) and then in 4 ED subgroups: Anorexia nervosa (AN), Bulimia nervosa (BN), ED Not Otherwise Specified (EDNOS), and AN/BN. Eighteen parameters were assessed at or near first presentation: cholesterol, folate, vitamin B12, magnesium, manganese, zinc, calcium, potassium, urate, sodium, albumin, phosphate, ferritin, vitamin D, white cell count, neutrophils, red cell count and platelets. Results were analysed using IBM SPSS 21 and Microsoft Excel 2013 by two-tailed, one-sample t-tests (TG and 4 subgroups) and chi-square tests (TG only) and compared to the population mean standards. Results for the TG and each subgroup individually were then compared with the known reference interval (RI). For the total sample, t-tests showed significant differences for all parameters ( p  data would support routine measurement of a full blood count and electrolytes, phosphate, magnesium, liver function tests, ferritin, vitamin B12, red cell folate, vitamin D, manganese and zinc for all patients at first presentation with an ED.

  8. Artificial grammar learning in individuals with severe aphasia. (United States)

    Zimmerer, Vitor C; Cowell, Patricia E; Varley, Rosemary A


    One factor in syntactic impairment in aphasia might be damage to general structure processing systems. In such a case, deficits would be evident in the processing of syntactically structured non-linguistic information. To explore this hypothesis, we examined performances on artificial grammar learning (AGL) tasks in which the grammar was expressed in non-linguistic visual forms. In the first experiment, AGL behavior of four aphasic participants with severe syntactic impairment, five aphasic participants without syntactic impairment, and healthy controls was examined. Participants were trained on sequences of nonsense stimuli with the structure A(n)B(n). Data were analyzed at an individual level to identify different behavioral profiles and account for heterogeneity in aphasic as well as healthy groups. Healthy controls and patients without syntactic impairment were more likely to learn configurational (item order) than quantitative (counting) regularities. Quantitative regularities were only detected by individuals who also detected the configurational properties of the stimulus sequences. By contrast, two individuals with syntactic impairment learned quantitative regularities, but showed no sensitivity towards configurational structure. They also failed to detect configurational structure in a second experiment in which sequences were structured by the grammar A(+)B(+). We discuss the potential relationship between AGL and processing of word order as well as the potential of AGL in clinical practice. © 2013 Published by Elsevier Ltd.

  9. Effects of cognitive-behavioral therapy on Eating Disorders: neurotransmitter secretory response to treatment. (United States)

    Brambilla, F; Dalle Grave, R; Calugi, S; Marchesini, G; Baroni, S; Marazziti, D


    The effects of cognitive-behavioral therapy (CBT) on central dopamine (DA), noradrenaline (NE) and serotonin (5-HT) secretion were studied in a group of 50 female inpatients, of which 14 suffered from anorexia nervosa restricted type (AN-R), 14 from anorexia nervosa bingeing-purging type (AN-BP), and 22 from bulimia nervosa (BN). The aim of the study was to see whether or not CBT modifies the secretion of central DA (blood homovanillic acid=HVA), NE (blood 3-methoxy-4-hydroxy-phenylglycol=MHPG) and the 5-HT transporter (as evaluated by the platelet paroxetine binding=[(3)H]-Par-binding), if the physical and psychological effects of CBT correlate with changes of the neurotransmitter secretion; and if the biological effects of CBT are linked to specific psychopathological aspect of the disorders. The treatment lasted 20 weeks. Body-mass Index, bingeing and purging, specific AN-BN psychopathological (EDE 12-OD), depression (Beck Inventory), anxiety (STAY Form-Y-1), impulsiveness (Barratt Impulsiveness Scale), self-esteem (Rosenberg Self-Biochemical Scale) and temperament (Temperament and Character Inventory, Cloninger Scale) were assessed at baseline and at the end of the treatment. CBT significantly improved the psychophysical aspects of the diseases. HVA and MHPG concentrations did not change. The [(3)H]-Par-binding parameters, the maximum binding capacity (B(max)) and dissociation constant (K(d)) values did not change in either AN-R or AN-BP patients, while the [(3)H]-Par B(max) (and not the K(d)) increased significantly in BN patients. Correlations emerged between basal and final [(3)H]-Par B(max) values and psychopathological scores, but not between CBT-induced differences between basal and final values. Our data suggest that only in BN CBT may act through changes in 5-HT system function. Copyright 2009 Elsevier Ltd. All rights reserved.
