Marcolini F, Ravaglia A, Tempia Valenta S, Bosco G, Marconi G, De Ronchi D, Atti AR. Severe enduring anorexia nervosa (SE-AN) treatment options and their effectiveness: a review of literature. J Eat Disord 2024; 12:48. [PMID: 38654374 DOI: 10.1186/s40337-024-01006-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 04/16/2024] [Indexed: 04/25/2024] Open
Abstract
INTRODUCTION For nearly 20% of patients diagnosed with Anorexia Nervosa (AN), the eating disorder (ED) is prolonged and becomes long-lasting. It has been reported that patients diagnosed with Severe Enduring Anorexia Nervosa (SE-AN) have worse ED symptoms, higher rates of lifetime hospitalization, and lower psychosocial well-being compared to patients with shorter disease duration. OBJECTIVES This review aims to describe the treatments proposed to date and their effectiveness on SE-AN-related outcomes. METHODS We conducted a PubMed search for studies addressing the issue of treatment approach to SE-AN adults, that were published between 2003 and 2023, peer-reviewed, written in the English language, and available in full-text. Next, we inductively created relevant macro-themes by synthesizing the data from the included articles. RESULTS Of 251 PubMed studies, 25 articles were considered for data extraction, all published between 2003 and 2022. We identified three macro-themes. The first macro-theme, "Psychotherapy", mostly takes into consideration treatment effectiveness of cognitive behavioral therapy (CBT). Various reports determined its greater effectiveness compared to Specialist Supportive Clinical Management (SSCM), and one study proved that outpatient CBT is a valid alternative to hospitalization. The second one involves "Pharmacological Treatments". Research on dronabinol, a synthetic orexigenic cannabinoid, antipsychotics (in particular, olanzapine and haloperidol), and ketamine showed some mixed results regarding the often-complementary areas of weight gain and improvement in ED-related symptoms. Regarding the third macro-theme, "Brain Stimulation Therapies," such as Repetitive Transcranial Magnetic Stimulation (rTMS) and Deep Brain Stimulation (DBS), we found promising results in improving ED-related psychological traits (such as mood and anxiety), affective regulation, and quality of life. However, we have observed divergent results regarding outcome measures such as BMI and weight gain. CONCLUSIONS SE-AN patients are predicted to encounter both medical complications and psychological distress of increasing severity that will inevitably affect their quality of life; to our knowledge, research evidence on treatment options for SE-AN remains limited, and the methodological quality of studies is generally low. These findings denote the need to focus future research efforts on effective treatment strategies specific to long-lasting EDs.

Abstract
Eating disorders (EDs) are serious mental health conditions characterised by impaired eating behaviours and nutrition as well as disturbed body image, entailing considerable mortality and morbidity. Psychopharmacological medication is an important component in the treatment of EDs. In this review, we performed a historic analysis of pharmacotherapeutic research in EDs based on the scientific studies included in the recently published World Federation of Societies for Biological Psychiatry (WFSBP) guidelines for ED treatment. This analysis focuses on early approaches and trends in the methods of clinical pharmacological research in EDs, for example, the sample sizes of randomised controlled trials (RCTs). We found the development of psychopharmacological treatments for EDs followed advancements in psychiatric pharmacotherapy. However, the application of RCTs to the study of pharmacotherapy for EDs may be an impediment as limited participant numbers and inadequate research funding impede generalisability and statistical power. Moreover, current medication usage often deviates from guideline recommendations. In conclusion, the RCT model may not effectively capture the complexities of ED treatment, and funding limitations hinder research activity. Novel genetically/biologically based treatments are warranted. A more comprehensive understanding of EDs and individualised approaches should guide research and drug development for improved treatment outcomes.

J Eat Disord 2023; 11:151. [PMID: 37674209 PMCID: PMC10481458 DOI: 10.1186/s40337-023-00862-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Accepted: 08/07/2023] [Indexed: 09/08/2023] Open
Abstract
BACKGROUND Off-label antipsychotic use is not uncommon in youth with anorexia nervosa (AN), aiming to enhance suboptimal weight restoration, yet its efficacy remains debated, especially in youth. METHODS Retrospective chart review of consecutively admitted inpatients (ages 8-18 years) with restricting/binge-purge AN, comparing youth with versus without antipsychotic treatment regarding baseline factors, treatment, and anthropometric outcome characteristics including all patients and matched subgroups. Matched subsamples were also compared regarding faster versus slower weight change (median split). Furthermore, within-subject analyses compared weight gain trajectories before versus after antipsychotic use in antipsychotic-treated youth. These results were then compared in a pre-/post design with the matched control group without antipsychotic treatment, using the mean duration until antipsychotic use in the antipsychotic-treated group as the dividing timeline, controlling for a potential order effect, in that later rather than earlier antipsychotic treatment for AN may be more successful. RESULTS Of 294 youth with AN (median age = 15.2 (interquartile range = 14.0, 16.6) years, females = 96.6%, restricting subtype = 81.0%, hospitalization duration = 98.2 ± 43.2 days), 44 (15.0%) underwent 52 antipsychotic trials (olanzapine = 63.5%). In multivariable analyses, antipsychotic use was independently associated with younger age, childhood physical abuse history, comorbid borderline personality traits, and lower pre-antipsychotic weight gain (p < 0.0001). In unmatched groups, antipsychotic-treated versus non-treated youth had significantly lower discharge anthropometric parameters, longer inpatient treatment, and lower weight change/week (p < 0.001-p = 0.005), without significant differences between olanzapine and non-olanzapine antipsychotics (p = 0.27-0.44). Non-significant antipsychotic effects on weight outcomes were confirmed in (1) matched subgroups of antipsychotic-treated versus non-treated youth (n = 43 each), (2) youth with faster versus slower weight gain (n = 21 vs. n = 22), and (3) antipsychotic-treated youth when comparing weight change before versus after antipsychotic use (n = 31). Moreover, in antipsychotic-treated youth, weight change/week remained significantly lower versus matched non-antipsychotic-treated youth (n = 31) both before (p = 0.053) and after (p = 0.006) the median time (5 weeks) until antipsychotic use. CONCLUSIONS In this naturalistic study, clinician's antipsychotic choice, given to a more severely ill subgroup of adolescents with AN, did not significantly improve overall worse weight change trajectories during inpatient treatment, even in matched subgroups. Randomized trials in individuals reflecting real-world samples are needed to evaluate the utility of antipsychotic treatment in youth with AN.

Abstract
OBJECTIVES This 2023 update of the WFSBP guidelines for the pharmacological treatment of eating disorders (EDs) reflects the latest diagnostic and psychopharmacological progress and the improved WFSBP recommendations for the assessment of the level of evidence (LoE) and the grade of recommendation (GoR). METHODS The WFSBP Task Force EDs reviewed the relevant literature and provided a timely grading of the LoE and the GoR. RESULTS In anorexia nervosa (AN), only a limited recommendation (LoE: A; GoR: 2) for olanzapine can be given, because the available evidence is restricted to weight gain, and its effect on psychopathology is less clear. In bulimia nervosa (BN), the current literature prompts a recommendation for fluoxetine (LoE: A; GoR: 1) or topiramate (LoE: A; GoR: 1). In binge-eating disorder (BED), lisdexamfetamine (LDX; LoE: A; GoR: 1) or topiramate (LoE: A; GoR: 1) can be recommended. There is only sparse evidence for the drug treatment of avoidant restrictive food intake disorder (ARFID), pica, and rumination disorder (RD). CONCLUSION In BN, fluoxetine, and topiramate, and in BED, LDX and topiramate can be recommended. Despite the published evidence, olanzapine and topiramate have not received marketing authorisation for use in EDs from any medicine regulatory agency.

Abstract
AbstractAnorexia nervosa (AN) is a type of eating disorder that has been increasing in incidence and has been encountered more commonly by physicians in their daily practice. Both environmental and genetic risk factors paired along with a more susceptible neurobiology are at play in the emerging resistance to treatment in AN. Preoccupations with intense fear of weight gain, dietary restrictions, excessive exercise, and how the individual is perceived by society mixed with underlying psychopathology all further add to the issue. Many patients who fall into this cycle of obsessive and restrictive patterns refuse to get treatment. As clinicians, it is essential we recognize the early signs of both eating disorders during the initial primary care appointments.To review the literature on the etiology of AN, possible misdiagnosis leading to inappropriate management of this condition, and understand the treatment-resistant AN and its management. Additionally, it will explore possible reasons that contribute to the resistance to treatment, the underlying psychopathology of anorexics, its genetic predisposition, psychiatric comorbidities, identification of the early signs and symptoms, and timely prevention.Early recognition by a physician includes a thorough history and physical examination, pertinent laboratory, and electrolyte studies, and identifying comorbid psychiatric conditions. The treatment of AN is intricate and requires a holistic approach. Treatment includes multiple modalities such as nutritional rehabilitation and psychosocial and pharmacological therapies. An interdisciplinary team of medical professionals for managing chronic AN is recommended.

Abstract
Drugs are widely prescribed for anorexia nervosa in the nutritional, somatic, and psychiatric fields. There is no systematic overview in the literature, which simultaneously covers all these types of medication. The main aims of this paper are (1) to offer clinicians an overview of the evidence-based data in the literature concerning the medication (psychotropic drugs and medication for somatic and nutritional complications) in the field of anorexia nervosa since the 1960s, (2) to draw practical conclusions for everyday practise and future research. Searches were performed on three online databases, namely MEDLINE, Epistemonikos and Web of Science. Papers published between September 2011 and January 2019 were considered. Evidence-based data were identified from meta-analyses, if there were none, from systematic reviews, and otherwise from trials (randomized or if not open-label studies). Evidence-based results are scarce. No psychotropic medication has proved efficacious in terms of weight gain, and there is only weak data suggesting it can alleviate certain psychiatric symptoms. Concerning nutritional and somatic conditions, while there is no specific, approved medication, it seems essential not to neglect the interest of innovative therapeutic strategies to treat multi-organic comorbidities. In the final section we discuss how to use these medications in the overall approach to the treatment of anorexia nervosa.

Abstract
PURPOSE To investigate the presence of mood spectrum signs and symptoms in patients with anorexia nervosa, restricting subtype (AN-R) or bulimia nervosa (BN). METHOD 55 consecutive female patients meeting DSM-IV criteria for eating disorders (EDs) not satisfying DSM-IV criteria for Axis I mood disorders were evaluated with the Lifetime Mood Spectrum Self-Report (MOODS-SR) and the Mini-International Neuropsychiatric Interview (MINI). The MOODS-SR explored the subthreshold comorbidity for mood spectrum symptoms in patients not reaching the threshold for a mood disorder Axis I diagnosis. MOODS-SR included 161 items. Separate factor analyses of MOODS-SR identified 6 'depressive factors' and 9 'manic-hypomanic factors'. RESULTS The mean total score of MOODS-SR was significantly higher in BN than in AN-R patients (97.5 ± 25.4 vs 61.1 ± 38.5, respectively; p = 0.0001). 63.6 % of the sample (n = 35) endorsed the threshold of ≥61 items, with a statistically significant difference between AN-R and BN (39.3 % vs 88.9 %; χ 2 = 14.6; df = 1; p = 0.0001). Patients with BN scored significantly higher than AN-R patients on several MOODS-SR factors: (a) MOODS-SR depressive component: 'depressive mood' (11.2 ± 7.4 vs 16.0 ± 5.8; p < 0.05), 'psychomotor retardation' (5.4 ± 5.6 vs 8.9 ± 3.8; p = 0.003), 'psychotic features' (2.0 ± 1.8 vs 4.1 ± 1.6; p = 0.001), 'neurovegetative symptoms' (5.0 ± 2.6 vs 7.7 ± 1.7; p = 0.001); (b) MOODS-SR manic/hypomanic component: 'psychomotor activation' (4.3 ± 3.6 vs 7.4 ± 3.1; p = 0.002), 'mixed instability' (1.0 ± 1.5 vs 2.0 ± 1.6; p < 0.05), 'mixed irritability' (2.5 ± 1.8 vs 3.7 ± 1.6; p < 0.05), 'inflated self-esteem' (1.1 ± 1.4 vs 2.1 ± 1.6; p < 0.05), and 'wastefulness/recklessness' (1.0 ± 1.4 vs 2.0 ± 1.2; p = 0.009). CONCLUSIONS MOODS-SR identifies subthreshold mood signs/symptoms among patients with AN-R, and BN and with no Axis I comorbidity for mood disorders, and provides a better definition of clinical phenotypes.

Abstract
Anorexia nervosa (AN) is a severe psychiatric disorder without approved medication intervention. Every class of psychoactive medication has been tried to improve treatment outcome; however, randomized controlled trials have been ambiguous at best and across studies have not shown robust improvements in weight gain and recovery. Here we review the available literature on pharmacological interventions since AN came to greater public recognition in the 1960s, including a critical review of why those trials may not have been successful. We further provide a neurobiological background for the disorder and discuss how cognition, learning, and emotion-regulating circuits could become treatment targets in the future. Making every effort to develop effective pharmacological treatment options for AN is imperative as it continues to be a complex psychiatric disorder with high disease burden and mortality.

Abstract
The aim of this review was to summarize evidence from research on psychopharmacological options for adult patients with anorexia nervosa (AN). Database searches of MEDLINE and PsycINFO (from January 1966 to January 2014) were performed, and original articles published as full papers, brief reports, case reports, or case series were included. Forty-one papers were screened in detail, and salient characteristics of pharmacological options for AN were summarized for drug classes. The body of evidence for the efficacy of pharmacotherapy in AN was unsatisfactory, the quality of observations was questionable (eg, the majority were not blinded), and sample size was often small. More trials are needed, while considering that nonresponse and nonremission are typical of patients with AN.

Abstract
BACKGROUND Treatments of eating disorders result too often in partial psychological and physical remission, chronicization, dropout, relapse and death, with no fully known explanations for this failure. In order to clarify this problem, we conducted three studies to identify the biochemical background of cognitive-behavioural psychotherapy (CBT), individual psychology brief psychotherapy (IBPP), and psychotherapy-pharmacotherapy with CBT + olanzapine in anorexics (AN) and bulimics (BN) by measuring the levels of plasma homovanillic acid (HVA) for dopamine secretion, plasma 3-methoxy-4-hydroxy-phenylglycol (MHPG) for noradrenalin secretion, and platelet [3H]-Paroxetin-binding Bmax and Kd for serotonin transporter function. The data were then compared with psychopathological and physical alterations. METHODS Study 1 investigated the effects of 4 months of CBT on plasma HVA, MHPG and [3H]-Par-binding in 14 AN-restricted, 14 AN-bingeing/purging, and 22 BN inpatients. Study 2 investigated the effects of 4 months of IBPP on plasma HVA in 15 AN and 17 BN outpatients. Study 3 investigated the effect of 3 months of CBT + olanzapine (5 mg/day) in 30 AN outpatients. The data were analyzed using one-way ANOVA for repeated measures for the changes between basal and post-treatment biological and psychological parameters, two-way ANOVA for repeated measures for the differences in the psychobiological data in the 3 groups, Spearman's test for the correlations between basal and final changes in the psychological and biological scores. RESULTS Study 1 revealed significant amelioration of the psychopathology in the AN and BN patients, no effects on HVA, MHPG or Paroxetin binding Kd, and a significant increase in Par-binding Bmax only in the BN patients. Study 2 revealed a significant effect of IBPP on psychopathology in the AN and BN patients, and a significant increase in HVA only in the BN patients. Study 3 revealed a significant positive effect of CBT + olanzapine therapy on the psychopathology and increased HVA values. No correlations were observed in the 3 groups between biological and psychological effects of the three treatments. CONCLUSIONS Our data advance suggestions on the mechanism of action of the three therapies; however, the lack of correlations between biochemical and psychological effects casts doubt on their significance.

Abstract
Psychotic disorders and eating disorders sometimes occur in the same person, and sometimes, but not always, at the same time. This can cause diagnostic confusion and uncertainty about treatment. This paper examines seven ways in which symptoms of both conditions can co-exist. The literature on this topic consists to a large extent of case reports, so that firm conclusions cannot be drawn from their examination. There is no consistent sequence in the co-occurrence of the two conditions-eating disorders sometimes precede, and sometimes follow the onset of psychosis. The advent of the psychosis, and sometimes the treatment of the psychosis can cure the eating disorder, but it can sometimes aggravate it. Psychosis is not necessarily a mark of severity in the course of an eating disorder, and food refusal can occur independent of severity in psychotic illness, but it can be a cause of death. There is some genetic association and some overlap of physiologic, cognitive and brain structure deficits in the two types of disorder. The connection between the two, however, remains speculative. The area of comorbidity and overlapping symptoms in psychiatry requires more research. Clinical recommendations include attention to the different individual ways in which these two disparate conditions often overlap.

Abstract
BACKGROUND Treatment resistance is an omnipresent frustration in eating disorders. Attempts to identify the features of this resistance and subsequently develop novel treatments have had modest effects. This selective review examines treatment resistant features expressed in core eating disorder psychopathology, comorbidities and biological features. Novel treatments addressing resistance are discussed. DESCRIPTION The core eating disorder psychopathology of anorexia nervosa becomes a coping mechanism likely via vulnerable neurobiological features and conditioned learning to deal with life events. Thus it is reinforcing and ego syntonic resulting in resistance to treatment. The severity of core features such as preoccupations with body image, weight, eating and exercising predicts greater resistance to treatment. Bulimia nervosa patients are less resistant to treatment with treatment failure related to greater body image concerns, impulsivity, depression, severe diet restriction and poor social adjustment. For those with binge eating disorder overweight in childhood and high emotional eating predicts treatment resistance. There is suggestive data that a diagnosis of an anxiety disorder and severe perfectionism may confer treatment resistance in anorexia nervosa and substance use disorders or personality disorders with impulse control problems may produce resistance to treatment in bulimia nervosa. Traits such as perfectionism, cognitive inflexibility and negative affect with likely genetic influences may also affect treatment resistance. Pharmacotherapy and novel therapies have been developed to address treatment resistance. Atypical antipsychotic drugs have shown some effect in treatment resistant anorexia nervosa and topiramate and high doses of SSRIs are helpful for treatment of resistant binge eating disorder patients. There are insufficient randomized controlled trials to evaluate the novel psychotherapies which are primarily based on the core psychopathological features of the eating disorders. CONCLUSION Treatment resistance in eating disorders is usually predicted by the severity of the core eating disorder psychopathology which develops from an interaction between environmental risk factors with genetic traits and a vulnerable neurobiology. Future investigations of the biological features and neurocircuitry of the core eating disorders psychopathology and behaviors may provide information for more successful treatment interventions.

Abstract
Here we report on a case series chart review conducted on nine severe and treatment-resistant patients with anorexia nervosa, body mass index < 13 kg/m(2), and a delusional body image disturbance. Patients received low doses of haloperidol during hospitalization. Haloperidol was well tolerated. The delusional body image disturbance and the drive for thinness were subjectively perceived as less intense. BMI increased from the initial 12.2 ± 0.5 to 16.0 ± 1.5 kg/m(2). Mean pulse rate and blood pressure did not change significantly from admission to discharge (66 ± 11.6 bpm; 91/56 mmHg vs 77 ± 12.0 bpm; 102/66 mmHg). Mean of QTc, available from electrocardiograms performed during hospitalization, was 413 ± 38.5 ms (range 342-469 ms). Further investigations are warranted to elucidate clinical usefulness and safety of low doses of haloperidol for patients with treatment-resistant anorexia and delusional body image disturbance.

Abstract
With this paper we aimed to describe a case of a woman affected by Anorexia Nervosa Restricting subtype (AN-R) with delusional symptoms, visual hallucinations and severe body image distortion. We discussed the main AN diagnosis and whether delusional symptoms could be related to severity of AN describing also the use of olanzapine in such a severe clinical condition. The use of olanzapine was found to be effective to reduce both delusions and body distortions, and to improve compliance to treatments. We found a severe delusional symptomatology with mystic, omnipotence and persecution features. The psychotic structure seemed preceding the eating disorder and was also found to be worsened by emaciation. The use of antipsychotic helped reducing delusional symptoms and improving compliance to treatments. Finally, the dynamically oriented therapeutic relationship helped the patient to gain weight and to achieve a full recovery from psychotic symptoms.

Abstract
OBJECTIVE Many patients with anorexia nervosa develop an intractable and debilitating illness course. Our aims were to (i) conduct a systematic review of randomised controlled trials (RCTs) of treatment for chronic anorexia nervosa participants, and (ii) identify research informing novel therapeutic approaches for this group. METHODS Systematic search (SCOPUS plus previous reviews date 2011) of literature for (i) RCTs of treatment that included anorexia nervosa participants with a mean duration of illness of at least 3 years, (ii) studies reporting new treatments addressing factors associated with chronicity. RESULTS Evidence of efficacy for treatment approaches in severe and enduring anorexia nervosa is limited. Only one unpublished RCT designed to test a specific psychological approach for these patients was identified. There is a probable advantage for specialist psychotherapy over treatment as usual, and a promising study of relapse prevention with cognitive behaviour therapy (CBT) for anorexia nervosa (CBT-AN). Open trials have, however, reported developments in psychological therapies that warrant further specific evaluation. These include forms of CBT modified for anorexia nervosa, cognitive remediation therapy with emotion skills training, the Maudsley Model for Treatment of Adults with Anorexia Nervosa, the Community Outreach Partnership Program, Specialist Supportive Clinical Management and the approach of Strober with its emphasis on therapeutic alliance and flexible goals. CONCLUSIONS Treatment trials need to move beyond targeting core eating disorder pathology (primarily weight restoration) and examine efficacy and effectiveness in minimising harm and reducing personal and social costs of chronic illness. There is also a need to develop better definitions of chronicity, with or without treatment 'resistance' specifiers.

Abstract
Anorexia nervosa (AN) is a severe psychiatric disorder associated with food avoidance and malnutrition. In this study, we wanted to test whether we would find brain reward alterations in AN, compared with individuals with normal or increased body weight. We studied 21 underweight, restricting-type AN (age M 22.5, SD 5.8 years), 19 obese (age M 27.1, SD 6.7 years), and 23 healthy control women (age M 24.8, SD 5.6 years), using blood oxygen level-dependent functional magnetic resonance brain imaging together with a reward-conditioning task. This paradigm involves learning the association between conditioned visual stimuli and unconditioned taste stimuli, as well as the unexpected violation of those learned associations. The task has been associated with activation of brain dopamine reward circuits, and it allows the comparison of actual brain response with expected brain activation based on established neuronal models. A group-by-task condition analysis (family-wise-error-corrected P<0.05) indicated that the orbitofrontal cortex differentiated all three groups. The dopamine model reward-learning signal distinguished groups in the anteroventral striatum, insula, and prefrontal cortex (P<0.001, 25 voxel cluster threshold), with brain responses that were greater in the AN group, but lesser in the obese group, compared with controls. These results suggest that brain reward circuits are more responsive to food stimuli in AN, but less responsive in obese women. The mechanism for this association is uncertain, but these brain reward response patterns could be biomarkers for the respective weight state.

Abstract
OBJECTIVES The treatment of eating disorders is a complex process that relies not only on the use of psychotropic drugs but should include also nutritional counselling, psychotherapy and the treatment of the medical complications, where they are present. In this review recommendations for the pharmacological treatment of eating disorders (anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED)) are presented, based on the available literature. METHODS The guidelines for the pharmacological treatment of eating disorders are based on studies published between 1977 and 2010. A search of the literature included: anorexia nervosa bulimia nervosa, eating disorder and binge eating disorder. Many compounds have been studied in the therapy of eating disorders (AN: antidepressants (TCA, SSRIs), antipsychotics, antihistaminics, prokinetic agents, zinc, Lithium, naltrexone, human growth hormone, cannabis, clonidine and tube feeding; BN: antidepressants (TCA, SSRIs, RIMA, NRI, other AD), antiepileptics, odansetron, d-fenfluramine Lithium, naltrexone, methylphenidate and light therapy; BED: antidepressants (TCA, SSRIs, SNRIs, NRI), antiepileptics, baclofen, orlistat, d-fenfluramine, naltrexone). RESULTS In AN 20 randomized controlled trials (RCT) could be identified. For zinc supplementation there is a grade B evidence for AN. For olanzapine there is a category grade B evidence for weight gain. For the other atypical antipsychotics there is grade C evidence. In BN 36 RCT could be identified. For tricyclic antidepressants a grade A evidence exists with a moderate-risk-benefit ratio. For fluoxetine a category grade A evidence exists with a good risk-benefit ratio. For topiramate a grade 2 recommendation can be made. In BED 26 RCT could be identified. For the SSRI sertraline and the antiepileptic topiramate a grade A evidence exists, with different recommendation grades. CONCLUSIONS Additional research is needed for the improvement of the treatment of eating disorders. Especially for anorexia nervosa there is a need for further pharmacological treatment strategies.

Abstract
OBJECTIVE The pathophysiology of eating disorders such as anorexia nervosa (AN) and bulimia nervosa (BN) has been linked to an impaired dopaminergic neurotransmission, still the origin of this disturbance remains unknown. The aim of the present study was, therefore, to evaluate whether the expression of dopaminergic genes is altered in the blood of patients suffering from eating disorders and if these alterations can be explained by changes in the promoter specific DNA methylation of the genes. METHOD We used quantitative real-time PCR to measure both the expression and the promoter specific DNA methylation of the dopamine transporter (DAT), and the D2 (DRD2) and D4 receptor (DRD4) gene in the blood of 46 patients (22 AN, 24 BN) and 30 healthy controls. RESULTS Patients showed an elevated expression of DAT mRNA when compared with the controls and a downregulation of the DRD₂ expression. The upregulation of the DAT gene was accompanied by a hypermethylation of the gene's promoter in the AN and BN group while a significant hypermethylation of the DRD₂ promoter was only present in the AN group. No differences in expression or methylation were found for the other dopamine receptors investigated. DISCUSSION Our study shows a disturbed expression of dopaminergic genes that is accompanied by a dysregulation of the epigenetic DNA methylation. Further studies are necessary to provide more insight into the epigenetic dysregulation of the dopaminergic neurotransmission in the pathophysiology of eating disorders.

Abstract
Anorexia nervosa and bulimia nervosa are primarily psychiatric disorders characterized by severe disturbances of eating behavior. Eating disorders are most prevalent in the Western culture where food is in abundance and female attractiveness is equated with thinness. Eating disorders are rare in countries like India. Despite a plethora of management options available to the mental health professionals, no major breakthrough has been achieved in recent years. Nutritional rehabilitation along with some form of re educative psychotherapy remains the mainstay of management of anorexia nervosa. In bulimia nervosa, both fluoxetine and cognitive behavior therapy have been found to be effective. Although the above-mentioned management options have been in use for decades, the active ingredient is still to be ascertained.

Abstract
OBJECTIVE A systematic analysis of data collected with the Eating Disorder Inventory (EDI) was made. METHOD A literature search identified 94 sources in which the mean values of the EDI or EDI-2 subscales were reported, comprising 310 samples differing by sex, age, diagnosis, language, ethnicity, or some other relevant attribute. The total number of respondents was 43,722, from 25 different countries, having used the EDI in one of the 16 languages (1-94). RESULTS The factorial structure of the aggregate means of the EDI subscales, for both clinical versus nonclinical and Western versus non-Western samples, was almost identical suggesting generalizability across languages and cultures. Non-Western participants scored higher than Western participants on virtually all EDI subscales, both in normal and eating-disordered samples. It was shown that age is a risk factor when someone is already diagnosed with an eating disorder but, in the general population, increasing age reduces the likelihood of being afflicted by eating disorders. DISCUSSION Symptoms of eating disorders are more pronounced in non-Western than in Western samples.

Abstract
OBJECTIVE To review selected issues regarding the development of drug treatments for anorexia nervosa (AN). METHOD The existing pharmacotherapy literature for AN is reviewed, and the theoretical and practical considerations are discussed. RESULTS A very wide variety of drugs have been examined in AN, generally with negative results. There are a number of potential reasons for this finding, including compliance, nutritional deficits, selection of the wrong targets or the wrong outcome measures, use of monotherapy, lack of animal models, or factors intrinsic to AN. CONCLUSION Pharmacotherapy provides little benefit in the treatment of AN at present. Several strategies might lead to the identification of more effective agents, including new measurement strategies, identification of novel pharmacologic targets, and consideration of a clinical trials network.

Abstract
OBJECTIVE Activity-based anorexia is an animal model of anorexia nervosa in which limited access to standard lab chow combined with voluntary wheel running leads to hypophagia and severe weight loss. This study tested whether activity-based anorexia could be prevented or reversed with palatable foods. METHOD Male rats were divided into sedentary or ad libitum-running groups and maintained on 1 h daily access to standard chow plus one of the following: sugar, saccharin, vegetable fat (shortening), or sweet high-fat chow. RESULTS Access to the sweet high-fat chow both reversed and prevented the weight loss typical of activity-based anorexia. Vegetable fat attenuated body weight loss, but to a lesser degree than the sweet high-fat diet. The addition of saccharin or sucrose solutions to the standard lab-chow diet had no effect. CONCLUSION The results suggest that certain palatable diets may affect the development of, and recovery from, activity-based anorexia.

Abstract
Dopaminergic abnormalities have been described in anorexia nervosa but studies about plasma level of homovanillic acid (pHVA) have yielded conflicting results probably due to the small number and the heterogeneity of patients. Plasma HVA, nutritional and hormonal parameters and several scales - the Eating Attitudes Test (EAT), the Beck Depression Inventory (BDI), the Leyton Obsessional Inventory-child version (LOI-C) and the State and Trait Anxiety Inventory (STAI) - were assessed in 44 adolescent anorexia nervosa patients (mean age 14.7 years, SD 1.7) consecutively admitted to an Eating Disorder Unit. They were evaluated at admission, at discharge and, in 34 cases, after 9 months of follow-up. pHVA was also assessed in 16 control adolescents. Patients had significantly higher pHVA than controls (p = .002). About 31% of patients had a very high level of pHVA, a significantly higher (p = .006) mean score in the BDI and a non significantly higher mean score in the EAT. After weight recovery some laboratory parameters improved as well as the EAT (p = .019), the BDI (p = 001) and the Interference score of the LOI-C (p = .004). Moreover, pHVA decreased significantly (p=.036). At follow-up, patients with normal weight had lower (p = .037) pHVA than patients with low weight. The conclusion would be that there is a dopaminergic dysfunction in anorexic patients, specially in a subgroup with high depressive and anorexic symptomatology. With weight recovery and psychopathological improvement, pHVA tends to normalization.

Abstract
Schizotypal personality disorder (SPD) has rarely been reported as an eating disorder-related personality trait. A 23-year-old woman was diagnosed as having anorexia nervosa binge eating/purging type. At the age of 53 years, she was admitted to Jikei University Hospital because of excessive bodyweight loss. She was diagnosed as having SPD based on bizarre behavior, ideation and a tendency to seek isolation. She was treated with low-dose antipsychotics, and her impulsive behavior improved. The patient's SPD was considered to have had a psychopathological contribution to her chronic episodes of anorexia nervosa.

Abstract
Dopamine impairments occur in anorexia nervosa. The aim of this study was to see whether treatment with the atypical dopamine antagonist antipsychotic olanzapine improves the disorder. Thirty anorexics, 18 restricted and 12 bingeing-purging, underwent a 3-month course of cognitive behavioral therapy, plus at random and double-blinded oral olanzapine (2.5 mg for 1 month, 5 mg for 2 months) in half and oral placebo in the other half of them. BMI, psychopathological aspects (eating disorder inventory, Hamilton Rating Scale, Buss-Durkee Rating Scale, Yale Brown Cornell for Eating Disorders Rating Scale, temperament-character inventory), and homovanillic acid blood concentrations for dopamine secretion, were monitored at baseline and then monthly during the trial. At the end of the trial BMI, total eating disorder inventory, total Yale Brown Cornell for Eating Disorders Rating Scale, Buss-Durkee Rating Scale, Hamilton Rating Scale scores and in olanzapine-treated patients the subitems of eating disorder inventory ineffectiveness and maturity fear, of Buss-Durkee Rating Scale direct aggressiveness, of temperament-characteristic inventory persistence had improved significantly. When stratified for anorexia nervosa subtype, BMI changes were significant among anorexia nervosa bingeing-purging patient, 'depression' (Hamilton Rating Scale) and 'direct aggressiveness' (Buss-Durkee Rating Scale) among anorexia nervosa bingeing-purging patients, 'persistence' (temprerament-characteristic inventory), among anorexics restricted patients, with a trend toward significance for obsessivity-compulsivity (Yale Brown Cornell for Eating Disorders Rating Scale). homovanilic acid blood levels increased significantly in the cognitive behavioral therapy+olanzapine group. No correlations were observed between homovanilic acid concentrations and psychopathological parameters. The pharmacological treatment can significantly improve specific aspects of anorexia nervosa.

Abstract
BACKGROUND Several lines of evidence support the possibility that disturbances of dopamine (DA) function could contribute to alterations of weight, feeding, motor activity, and reward in anorexia nervosa (AN). METHODS To assess possibly trait-related disturbances but avoid confounding effects of malnutrition, 10 women who were recovered from AN (REC AN) were compared with 12 healthy control women (CW). Positron emission tomography with [(11)C]raclopride was used to assess DA D2/D3 receptor binding. RESULTS The women who were recovered from AN had significantly higher [(11)C]raclopride binding potential in the antero-ventral striatum than CW. For REC AN, [(11)C]raclopride binding potential was positively related to harm avoidance in the dorsal caudate and dorsal putamen. CONCLUSIONS These data lend support for the possibility that decreased intrasynaptic DA concentration or increased D2/D3 receptor density or affinity is associated with AN and might contribute to the characteristic harm avoidance or increased physical activity found in AN. Most intriguing is the possibility that individuals with AN might have a DA related disturbance of reward mechanisms contributing to altered hedonics of feeding behavior and their ascetic, anhedonic temperament.

Abstract
The pathophysiology of anorexia nervosa (AN) is complex and involves alterations of serotonin, dopamine and histamine neurotransmitters. In addition, receptor activity is disturbed, presumably in response to the neurotransmitter changes. These alterations are reviewed in relation to symptomatology and outcome of AN. Neuropeptide and peripheral orexigenic and satiety peptide research is in its infancy but holds much promise to shed light on the pathophysiological mechanisms involved in this illness. Current drug therapies have not demonstrated the efficacy desired in the treatment of AN. Current therapies are reviewed and new drug targets are explored. Compounds that interact with serotonin, histamine and dopamine receptors may offer unique treatment opportunities. In the future, the manipulation of peptides may add to the therapeutic potential of pharmacotherapy.

Abstract
OBJECTIVE To review serotonergic and dopaminergic system function in anorexia nervosa in terms of potential modulation by atypical antipsychotic medications. METHOD A systematic review of clinical, neurobiological and functional neuroimaging findings of serotonergic and dopaminergic system activity in anorexia nervosa was conducted via MEDLINE, PsycINFO and EMBASE psychiatry databases, with a critical review of dysregulation of these systems as therapeutic targets for atypical antipsychotics, in context of evidence regarding the utility and efficacy of these medications in this syndrome. RESULTS There is evidence of persistently altered serotonergic and dopaminergic function in anorexia nervosa independent to weight-recovery. Case reports, open-label and single-blinded studies, albeit sparse, suggest that atypical antipsychotics may be beneficial in the management of anorexia nervosa psychopathology beyond weight gain. CONCLUSIONS Double-blind placebo controlled studies of atypical antipsychotics in anorexia nervosa with well defined outcome measures are required.

Abstract
Currently, no medications are approved by the FDA for the treatment of anorexia nervosa (AN). However, there are several promising pharmacological targets. Treatment includes a weight restoration and a weight maintenance phase and different pharmacological treatments may be useful in one phase, but not the other. Although cyproheptadine has some modest benefit during the weight restoration phase, it is not widely used. Fluoxetine administered during the weight maintenance phase decreases relapse rate. The medications currently being most widely studied are the atypical antipsychotics, particularly olanzapine. Emerging evidence suggests that some AN patients have psychotic symptoms that may respond to antipsychotic agents. There are promising case reports and open-label studies of the atypical antipsychotics, but as yet, no randomised, placebo-controlled, double-blind studies have been reported. Additional novel treatment approaches are urgently needed for this group of severely ill patients who have a high premature mortality rate.

Abstract
Anorexia nervosa (AN) is a complex mental disorder presenting psychiatric and physical symptoms. Literature recognizes the role of several factors in the pathogenesis of this disorder, according to the biopsychosocial model. Many mechanisms are still partly unclear. Endocrine and metabolic alterations usually occur in AN, probably having a role in its pathogenesis and in the disorder perseverance. In consideration of the multifactorial pathogenesis, a multidisciplinary approach is needed in the treatment of anorexic patients. Up-to-date psychotherapy, psychopharmacological, endocrine and nutritional treatments are considered effective in improving AN. Literature does not however provide evidence of a single validated psychopharmacotherapy for anorexic patients. It is known that psychopharmacotherapy can influence hormonal and metabolic states in some conditions, but for the moment few data are present about these effects in AN. This article aims to review the data about the psychopharmacotherapy role in AN, focusing on the endocrine and metabolic effects of anti-depressants (AD) and novel antipsychotic drugs which seem to be the most effective in AN. Scant data are however available and further research should provide more evidence about these effects and also assess whether the severity of the neuroendocrine, hormonal and metabolic impairments can predict the lack of response to the psychopharmacological treatment with AD and neuroleptics.
