Abstract
Specific psychological treatments have demonstrated efficacy and represent the first-line approaches recommended for anorexia nervosa, bulimia nervosa, and binge-eating disorder. Unfortunately, many patients, particularly those with anorexia nervosa, do not derive sufficient benefit from existing treatments, and better or alternative treatments for eating disorders are needed. Less progress has been made in developing pharmacologic options for eating disorders. No medications approved for anorexia nervosa exist, and only one each exists for bulimia nervosa and for binge-eating disorder; available data indicate that most patients fail to benefit from available medications. Longer and combined treatments have generally not enhanced outcomes. This review presents emerging findings from more complex and clinically relevant adaptive treatment designs, as they offer some clinical guidance and may serve as models for future enhanced treatment research.

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.

Yu S, Zhang Y, Shen C, Shao F. Efficacy of pharmacotherapies for bulimia nervosa: a systematic review and meta-analysis. BMC Pharmacol Toxicol 2023; 24:72. [PMID: 38042827 PMCID: PMC10693702 DOI: 10.1186/s40360-023-00713-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Accepted: 11/24/2023] [Indexed: 12/04/2023] Open
Abstract
OBJECTIVE The main purpose was to evaluate the efficacy and tolerability of different medications used to treat bulimia nervosa (BN). METHODS Randomized controlled trials (RCTs) were identified from published sources through searches in PubMed, Cochrane Library, Web of Science, and Embase from inception to November 2022. Primary outcomes were changes in the frequency of binge eating episodes and vomiting episodes from baseline to endpoint. Secondary outcomes were differences in the improvement of scores in depressive symptoms, tolerability (dropout due to adverse events) and weight change. RESULTS The literature search ultimately included 11 drugs, 33 studies and 6 types of drugs, 8 trials with TCAs (imipramine, desipramine), 14 with SSRIs (fluoxetine, citalopram and fluvoxamine), 6 with MAOIs (phenelzine, moclobemide and brofaromine), 3 with antiepileptic drugs (topiramate), 1 with mood stabilizers (lithium), and 1 with amphetamine-type appetite suppressant (fenfluramine). The reduction in binge eating episodes was more likely due to these drugs than the placebo, and the SMD was -0.4 (95% CI -0.61 ~ -0.19); the changes in the frequency of vomiting episodes (SMD = -0.16, 95% CI -0.3 ~ -0.03); weight (WMD = -3.05, 95% CI -5.97 ~ -0.13); and depressive symptoms (SMD = -0.32, 95% CI -0.51 ~ -0.13). However, no significant difference was found in dropout due to adverse events (RR = 1.66, 95% CI 1.14 ~ 2.41). CONCLUSIONS This meta-analysis indicates that most pharmacotherapies decreased the frequency of binge-eating and vomiting episodes, body weight, and depressive symptoms in BN patients, but the efficacy was not significant. In each drug the efficacy is different, treating different aspects, different symptoms to improve the clinical performance of bulimia nervosa.

Abstract
BACKGROUND The concurrent assessment of weight and affective psychopathology outcomes relevant to the psychopharmacology of major eating disorders (EDs), namely anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED), warrants systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS PubMed, Scopus, and ClinicalTrials.gov were inquired from inception through August 31st, 2022, for RCTs documenting any psychopharmacological intervention for EDs diagnosed according to validated criteria and reporting weight and psychopathology changes. Adopted keywords were: "anorexia nervosa," "bulimia nervosa," "binge eating disorder," "antidepressant," "antipsychotic," and "mood stabilizer." No language restriction applied. RESULTS 5122 records were identified, and 203 full-texts were reviewed. Sixty-two studies entered the qualitative synthesis (AN = 22, BN = 23, BED = 17), of which 22 entered the meta-analysis (AN = 9, BN = 10, BED = 3). Concerning BMI increase in AN, olanzapine outperformed placebo (Hedges'g = 0.283, 95%C·I. = 0.051-0.515, I2 = 0 %; p = .017), whereas fluoxetine failed (Hedges'g = 0.351, 95%C.I. = -0.248 to 0.95, I2 = 63.37 %; p = .251). Fluoxetine not significantly changed weight (Hedges'g = 0.147, 95%C.I. = -0.157-0.451, I2 = 0 %; p = .343), reducing binging (Hedges'g = 0.203, 95%C.I. = 0.007-0.399, I2 = 0 %; p = .042), and purging episodes (Hedges'g = 0.328, 95%C.I. = -0.061-0.717, I2 = 58.97 %; p = .099) in BN. Lisdexamfetamine reduced weight (Hedges'g = 0.259, 95%C.I. = 0.071-0.446, I2 = 0 %; p = .007) and binging (Hedges'g = 0.571, 95%C.I. = 0.282-0.860, I2 = 53.84 %; p < .001) in BED. LIMITATIONS Small sample size, short duration, and lack of reliable operational definitions affect most of the included sponsored RCTs. CONCLUSIONS The efficacy of different drugs varies across different EDs, warranting additional primary studies recording broad psychopathological and cardiometabolic outcomes besides weight, especially against established psychotherapy interventions.

World Federation of Societies of Biological Psychiatry (WFSBP) guidelines update 2023 on the pharmacological treatment of eating disorders. World J Biol Psychiatry 2023:1-64.

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
PURPOSE Bulimia nervosa (BN) is an eating disorder characterized by binge eating, inappropriate compensatory behaviors, and body image concerns in persons at or above a healthy weight. BN is a serious disorder with medical sequelae and marked psychosocial impairment. To reduce and eliminate symptoms of BN, psychological and pharmacologic treatments for BN have been developed. We review the current state-of-the-art treatments for BN. METHODS We conducted a narrative review of the BN treatment literature to synthesize the current evidence base, provide recommendations, and propose future directions for BN treatment research. FINDINGS Currently, the first-line, state-of-the-art treatment for adults with BN is cognitive-behavioral therapy (CBT). Interpersonal therapy is a second-line evidence-based treatment for adults with BN, and dialectical behavior therapy and integrative cognitive-affective therapy are also promising. For BN in adolescents, family-based treatment for BN or CBT are evidence-based approaches. Pharmacotherapy is best considered adjunctive to psychotherapy in adults with BN but may be helpful, depending on the type of psychotherapy and whether psychotherapy is ineffective or unavailable. Fluoxetine 60 mg/d is the medication of choice for adults with BN. Little is known with respect to pharmacologic treatment of BN in adolescents, although fluoxetine 60 mg/d holds promise. IMPLICATIONS Despite decades of treatment-development research in BN, there is room for improvement because nearly 60% of those with BN do not achieve remission with specialty treatment and strikingly few randomized controlled trials for BN in adolescents exist. Moreover, the field should address issues related to treatment dissemination, access, and cost.

Abstract
There are few systematic studies of treatment of bulimia nervosa (BN) in adolescents. Although family-based treatment has demonstrated preliminary evidence to support involvement of caregivers in treatment, there is significant opportunity for improvement in mitigating binge-eating and purging symptoms among adolescents afflicted with BN. When caregivers are unable to participate in treatment, there is evidence that BN-specific cognitive behavioral therapy approaches are helpful for some adolescents. Further research is needed to determine for whom, and under what conditions certain types of family involvement might be most effective in adolescent treatment of BN.

Abstract
This paper reviews past and current progress in developing pharmacologic agents for the treatment of individuals with bulimia nervosa (BN). We searched the literature and clinical trial registries for compounds studied in BN, the related condition, binge eating disorder (BED), and preclinical models of binge-eating behavior. Drug classes evaluated included antidepressants, antiepileptic drugs, stimulants and other medications for attention-deficit/hyperactivity disorder, opioid antagonists, and weight loss agents, among others. The only available drugs with established efficacy in BN at this time include antidepressants (especially selective serotonin reuptake inhibitors [SSRIs]) and the antiepileptic topiramate, though the efficacy of these compounds is modest at best. The only medications we found currently receiving empirical study in people with BN were fluoxetine, other serotonergic antidepressants, intranasal naloxone, lisdexamfetamine dimesylate, phentermine-topiramate combination, the antiandrogenic oral contraceptive ethinyl estradiol plus drospirenone, and prazosin. Preclinical models suggest that nociceptin receptor antagonists, the selective serotonin 5-HT2C receptor agonist lorcaserin, monoamine stabilizers, and selective orexin-1 receptor antagonists might be helpful. We found no evidence of a drug developed specifically for the treatment of individuals with BN. Future areas for research in the pharmacotherapy of BN are suggested. Importantly, until drugs are developed specifically for eating disorders, drugs developed for other conditions that are centrally acting and associated with beneficial psychotropic effects and/or reduced appetite or weight loss might be considered for repurposing in BN.

Abstract
PURPOSE OF REVIEW Medications are commonly prescribed in the treatment of eating disorders. In this review, we discuss relevant medications used for the treatment of bulimia nervosa, binge eating disorder (BED), and anorexia nervosa. We focus on recent research developments, where applicable, in addition to discussing important findings from older studies to provide a complete synopsis of the current evidence base for eating disorder treatment using pharmacologic agents. RECENT FINDINGS Medications are generally useful for patients with bulimia nervosa and BED. For bulimia nervosa, antidepressant medications are the primary pharmacologic treatment and limited new research has been completed. For BED, lisdexamfetamine is reported to be generally well tolerated and effective, and is the first medication to be indicated by the US Food and Drug Administration for treatment of BED. For anorexia nervosa, there is limited evidence supporting benefits of medications. Second-generation antipsychotics, particularly olanzapine, appear to demonstrate some benefit for weight gain in anorexia nervosa, although are not advised as a stand-alone treatment. Transdermal administration of hormonal agents is also being explored for improving bone health in anorexia nervosa. SUMMARY Although pharmacotherapy has established utility in bulimia nervosa and BED, further research on medications for the treatment of eating disorders, particularly anorexia nervosa, is necessary.

Abstract
We examine the science and evidence supporting cognitive behavior therapy (CBT) for the treatment of bulimia nervosa and other eating disorders. Recent trials focusing on the abnormal cognitive and emotional aspects of bulimia have reported a remission rate of about 45%, and a relapse rate of about 30% within one year. However, an early CBT trial that emphasized the normalization of eating behavior had a better outcome than treatment that focused on cognitive intervention. In support of this finding, another treatment, that restores a normal eating behavior using mealtime feedback, has an estimated remission rate of about 75% and a relapse rate of about 10% over five years. Moreover, when eating behavior was normalized, cognitive and emotional abnormalities were resolved at remission without cognitive therapy. The critical aspect of the CBT treatment of bulimia nervosa therefore may actually have been the normalization of eating behavior.

Abstract
Anorexia nervosa and bulimia nervosa are serious psychiatric illnesses related to disordered eating and distorted body images. They both have significant medical complications associated with the weight loss and malnutrition of anorexia nervosa, as well as from the purging behaviors that characterize bulimia nervosa. No body system is spared from the adverse sequelae of these illnesses, especially as anorexia nervosa and bulimia nervosa become more severe and chronic. We review the medical complications that are associated with anorexia nervosa and bulimia nervosa, as well as the treatment for the complications. We also discuss the epidemiology and psychiatric comorbidities of these eating disorders.

Giner-Bartolomé C, Fagundo AB, Sánchez I, Jiménez-Murcia S, Santamaría JJ, Ladouceur R, Menchón JM, Fernández-Aranda F. Can an intervention based on a serious videogame prior to cognitive behavioral therapy be helpful in bulimia nervosa? A clinical case study. Front Psychol 2015; 6:982. [PMID: 26236261 PMCID: PMC4500862 DOI: 10.3389/fpsyg.2015.00982] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2015] [Accepted: 06/29/2015] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Several studies have highlighted the implications of impulsivity and novelty seeking for both the maintenance and the process of recovery from bulimia nervosa (BN). Cognitive behavioral therapy (CBT) is the treatment of choice for BN, but for some cases, this treatment alone might not be sufficient for reducing the high levels of impulsivity. The paper presents a case report of a patient with BN, examining the effectiveness of using a videogame (VG; Playmancer) as an additional intervention designed to address impulsivity. DESIGN Psychometric and neuropsychological measures were collected at baseline. After this assessment, Playmancer was applied prior to CBT, following an "A-B-A-C-A" single case experimental design. Impulsivity levels were assessed with the Conner's Continuous Performance Test II (CPT-II). After the Playmancer treatment, the patient started CBT, and the levels of impulsivity were recorded again. Finally, psychometric and neuropsychological measures were collected after treatment. Weekly frequency of binges and vomiting were also recorded during the entire procedure. RESULTS After the VG intervention, psychometric measures such as anxiety levels, impulsivity and novelty seeking decreased. Regarding the neuropsychological measures, impulsivity levels (measured with the CPT-II) progressively decreased throughout the intervention, and an improvement in decision making capacities was observed. Furthermore, the frequency of binges also decreased during and after the VG intervention. DISCUSSION This case report suggests that using the Playmancer VG to reduce impulsivity prior to CBT may enhance the final results of the treatment for BN.

Abstract
OBJECTIVE To provide a comprehensive review of pharmacotherapy and other biological treatments for eating disorders. METHOD Literature on this topic was systematically reviewed. RESULTS The bulimia nervosa (BN) literature underscores the utility of antidepressants, particularly SSRIs, in improving the symptoms of the disorder. The literature on binge eating disorder supports efficacy on reduction in binge eating frequency for a variety of compounds. However, such compounds have only modest effects on weight. Certain antiepileptic agents such as topiramate, if tolerated, are probably more useful in terms of weight loss. The number of controlled trials in patients with anorexia nervosa (AN) in particular has been quite small, and recent meta-analyses show disappointing results using atypical antipsychotics in AN. DISCUSSION The pharmacological treatment of eating disorders remains an underdeveloped field although drug therapy clearly plays a role in the treatment of those with BN and binge eating disorder. Other biological therapies have not been adequately studied.

Abstract
In recent years, research in the area of intervention development has been shifting from the traditional fixed-intervention approach to adaptive interventions, which allow greater individualization and adaptation of intervention options (i.e., intervention type and/or dosage) over time. Adaptive interventions are operationalized via a sequence of decision rules that specify how intervention options should be adapted to an individual's characteristics and changing needs, with the general aim to optimize the long-term effectiveness of the intervention. Here, we review adaptive interventions, discussing the potential contribution of this concept to research in the behavioral and social sciences. We then propose the sequential multiple assignment randomized trial (SMART), an experimental design useful for addressing research questions that inform the construction of high-quality adaptive interventions. To clarify the SMART approach and its advantages, we compare SMART with other experimental approaches. We also provide methods for analyzing data from SMART to address primary research questions that inform the construction of a high-quality adaptive intervention.

Abstract
Eating disorders are a significant source of psychiatric morbidity in young women and demonstrate high comorbidity with mood, anxiety, and substance use disorders. Thus, clinicians may encounter eating disorders in the context of treating other conditions. This review summarizes the efficacy of current and emerging treatments for anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Treatment trials were identified using electronic and manual searches and by reviewing abstracts from conference proceedings. Family based therapy has demonstrated superiority for adolescents with AN but no treatment has established superiority for adults. For BN, both 60 mg fluoxetine and cognitive behavioral therapy (CBT) have well-established efficacy. For BED, selective serotonin reuptake inhibitors, CBT, and interpersonal psychotherapy have demonstrated efficacy. Emerging directions for AN include investigation of the antipsychotic olanzapine and several novel psychosocial treatments. Future directions for BN and BED include increasing CBT disseminability, targeting affect regulation, and individualized stepped-care approaches.

Abstract
The paper presents a critical review (with search date 2010) of the major psychotropic medications assessed in eating disorders, namely antipsychotics, antidepressants, mood-stabilizing medications, anxiolytic and other agents. The evidence of efficacy of drug treatments is mostly weak or moderate. In addition, attrition rates are usually higher than for psychotherapies. However, there is support for use of antidepressants, particularly high-dose fluoxetine in bulimia nervosa, and anticonvulsants (topiramate) for binge-eating disorder. Low-dose antipsychotic medication may be clinically useful as adjunct treatment in acute anorexia, particularly where there is high anxiety and obsessive eating-related ruminations and failure to engage, but more trials are needed. Drug therapies such as topiramate and anti-obesity medication may aid weight loss in obese or overweight patients with binge-eating disorder; however, common or potentially serious adverse effects limit their use.

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
This review evaluated psychological treatments for Anorexia Nervosa, Bulimia Nervosa, and Binge Eating Disorder conducted in primary care. Five studies met inclusion criteria. Guided self-help cognitive-behavioral therapy via a self-help book may be a beneficial, first-line treatment for reducing binging and purging symptoms. Outcomes combining self-help with antidepressants remain unclear, although antidepressants alone may provide reduction of symptoms. High attrition and non-compliance rates among studies reviewed indicate the importance of a strong therapeutic alliance between provider and patient. Further research in primary care is needed to develop a standard of care for patients with eating disorders.

Abstract
BACKGROUND A retrospective chart review was undertaken in a private clinic to examine the clinical outcomes for patients with an eating disorder comorbid with depression or bipolar illness who underwent a referenced electroencephalographic (EEG) database analysis to help guide medication selection. METHOD We examined 33 charts for patients with the primary psychiatric diagnosis of an eating disorder and comorbid major depressive disorder or bipolar disorder who underwent a quantitative EEG database assessment to provide additional information for choices of medication. The current analysis includes data from 22 subjects who accepted treatments based on information from the referenced-EEG medication database. Hamilton Depression Rating Scale, Clinical Global Impression-Severity, Clinical Global Impression-Improvement, and hospitalization data were examined for these patients. RESULTS Patients whose EEG data was used for clinical treatment reported significant decreases in associated depressive symptoms (HDRS scores), overall severity of illness (Clinical Global Impression-Severity), and overall clinical global improvement (Clinical Global Impression- Improvement). This cohort also reported fewer inpatient, residential, and partial hospitalization program days following referenced-EEG compared with the two-year period prior to treatment. CONCLUSION These findings are consistent with previously reported data for patients with eating disorders and suggest the need for future studies using EEG data correlated with those from other patients with similar quantitative EEG features.

Abstract
Serotonergic dysregulation is thought to underlie much of the pathology in bulimia nervosa (BN). The purpose of this review is to expand the serotonergic model by incorporating specific and nonspecific contributions of estrogens to the development and maintenance of bulimic pathology in order to guide research from molecular genetics to novel therapeutics for BN. Special emphasis is given to the organizing theory of general brain arousal which allows for integration of specific and nonspecific effects of these systems on behavioral endpoints such as binge eating or purging as well as arousal states such as fear, novelty seeking, or sex. Regulation of the serotonergic system by estrogens is explored, and genetic, epigenetic, and environmental estrogen effects on bulimic pathology and risk factors are discussed. Genetic and neuroscientific research support this two-system conceptualization of BN with both contributions to the developmental and maintenance of the disorder. Implications of an estrogenic-serotonergic model of BN are discussed as well as guidelines and suggestions for future research and novel therapeutic targets.

Abstract
BACKGROUND A specific manual-based form of cognitive behavioural therapy (CBT) has been developed for the treatment of bulimia nervosa (CBT-BN) and other common related syndromes such as binge eating disorder. Other psychotherapies and modifications of CBT are also used. OBJECTIVES To evaluate the efficacy of CBT, CBT-BN and other psychotherapies in the treatment of adults with bulimia nervosa or related syndromes of recurrent binge eating. SEARCH STRATEGY Handsearch of The International Journal of Eating Disorders since first issue; database searches of MEDLINE, EXTRAMED, EMBASE, PsycInfo, CURRENT CONTENTS, LILACS, SCISEARCH, CENTRAL and the The Cochrane Collaboration Depression, Anxiety & Neurosis Controlled Trials Register; citation list searching and personal approaches to authors were used. Search date June 2007. SELECTION CRITERIA Randomised controlled trials of psychotherapy for adults with bulimia nervosa, binge eating disorder and/or eating disorder not otherwise specified (EDNOS) of a bulimic type which applied a standardised outcome methodology and had less than 50% drop-out rate. DATA COLLECTION AND ANALYSIS Data were analysed using the Review Manager software program. Relative risks were calculated for binary outcome data. Standardised mean differences were calculated for continuous variable outcome data. A random effects model was applied. MAIN RESULTS 48 studies (n = 3054 participants) were included. The review supported the efficacy of CBT and particularly CBT-BN in the treatment of people with bulimia nervosa and also (but less strongly due to the small number of trials) related eating disorder syndromes.Other psychotherapies were also efficacious, particularly interpersonal psychotherapy in the longer-term. Self-help approaches that used highly structured CBT treatment manuals were promising. Exposure and Response Prevention did not enhance the efficacy of CBT.Psychotherapy alone is unlikely to reduce or change body weight in people with bulimia nervosa or similar eating disorders. AUTHORS' CONCLUSIONS There is a small body of evidence for the efficacy of CBT in bulimia nervosa and similar syndromes, but the quality of trials is very variable and sample sizes are often small. More and larger trials are needed, particularly for binge eating disorder and other EDNOS syndromes. There is a need to develop more efficacious therapies for those with both a weight and an eating disorder.

Abstract
Numerous symptoms related to eating disorders have been shown to be influenced by serotonergic (5-HT) functioning, with the 5-HT(2A) receptor subtype being one of the most relevant involved in the pathophysiology of bulimia nervosa (BN). In line with this, Ca(2+) mobilization as mediated by 5-HT(2) receptors in platelets was shown to serve as a peripheral model for central nervous 5-HT functioning. Here, the 5-HT-induced intracellular Ca(2+) mobilization in platelets was measured in 13 female normal weight bulimic patients (14-18 years) upon admission and at the end of inpatient treatment. Findings were compared to 21 age-matched healthy female adolescents. 5-HT-induced Ca(2+) release was significantly decreased in bulimic patients upon admission and normalized during inpatient treatment. Antidepressive medication caused a significant improvement. The data provide further evidence that altered 5-HT(2) receptor functioning is involved in the pathophysiological underpinnings in BN.

Abstract
OBJECTIVE The objectives of this article were to study the course and outcome of longstanding eating disorders (ED) 5 years after completing treatment and to identify subgroups of patients with different course and outcome. METHOD A total of 77 patients with a mean age of 30 years were assessed at the beginning and end of in-patient therapy and at 1-, 2- and 5-year follow-up, respectively. RESULTS Of the 90% who participated in the 5-year follow-up, 46 patients (61%) had improved, and 30 (39%) did not meet diagnostic criteria for an ED. Cluster analysis identified a group of patient with no improvement over time. CONCLUSION Overall, the course is favourable, but a subgroup of patients with no improvement over time may need intensified treatment efforts.

Abstract
In the past 40 years, cognitive-behavior therapy (CBT) has emerged as the initial treatment of choice for patients with mild to moderate depression, anxiety disorders and other problems. In this paper, we discuss issues related to the dissemination and implementation of CBT in various practice settings as well as the use of manuals, computers, the telephone, and the Internet to aid dissemination and implementation. We review key aspects of CBT dissemination, such as the reach of CBT, models of dissemination, and obstacles and barriers to dissemination including patient interest, therapist training and research priorities. The effectiveness of manualized programs is considered, as well as the increasing sophistication of computer-assisted therapy. Stepped-care approaches are discussed as a viable solution to some of these barriers. We provide two examples of successful CBT dissemination, the Staying Free program, a smoking cessation program for inpatients, and the Improving Access to Psychological Therapies program in Britain, which aims to improve access to psychological therapy. We argue that two critical factors will determine the success of implementation of CBT in this century: 1) mandated outcomes and 2) leadership.

Abstract
Anorexia nervosa (AN), bulimia nervosa (BN) and binge-eating disorder (BED) are the three main eating disorders. Antidepressants, antipsychotics, anticonvulsants, prokinetic agents, opiate antagonists, appetite suppressants, tetrahydrocannabinol, cyproheptadine, zinc and ondansetron have been tested, and are frequently associated with psychological treatment. Selective serotonin reuptake inhibitors have a proven efficacy in BN and binge eating disorder. Other treatments, such as atypical antipsychotics in AN, anticonvulsants in BN and BED, and naltrexone and ondansetron in BN, may be promising, but lack the appropriate trials. The development of genetic researches in eating disorders may help the clinician to choose the most appropriate treatment in forthcoming years, using genetic polymorphisms of vulnerability genes, those linked to endophenotypes, or genes implicated in the metabolism of the drug treatment.

OBJECTIVE The purpose of this article is to review the extant treatment literature on bulimia nervosa and to offer suggestions for future research directions. METHOD The available treatment studies regarding both pharmacotherapy and psychotherapy are reviewed. RESULTS Both pharmacotherapy and psychotherapy appear to play a role in the treatment of bulimia nervosa; however, available data suggest that cognitive behavioral therapy remains the treatment of choice. CONCLUSION Additional work is clearly indicated regarding assisted and unassisted self-help. An enhanced form of CBT and the integrative cognitive-affective therapy both deserve further study. New approaches need to be piloted. More research is needed on treatment modeling.

Abstract
Bulimia nervosa is a disorder of complex etiology that tends to occur in young women. These individuals binge eat and purge by vomiting or other means, and often have depression, anxiety, substance abuse and extremes of impulse control. It is thought that binge eating and purging behaviors are, at least in part, a means of coping with dysphoric mood states and interpersonal stress. Bulimic symptoms are not likely to abate without development of new coping skills and behaviors. In the past 25 years, considerable progress has been made in developing specific psychotherapies and medication for the treatment of bulimia nervosa. Despite this progress, many individuals have partial responses to therapy and may remain chronically ill. This complex illness often requires a multidisciplinary team of professionals for effective management and, despite significant advances in treatment, bulimia nervosa continues to present major challenges for providers of care.

Abstract
The most studied and most frequently used pharmacologic treatments in bulimia nervosa are the selective serotonin reuptake inhibitors (SSRIs), in particular, fluoxetine. Less is known about the efficacy of the other SSRIs. To compare fluoxetine with citalopram in the treatment of bulimic patients, 37 bulimic patients were randomized to receive fluoxetine (n=18) or citalopram (n=19); these patients were assessed with regard to clinical (ie, body mass index, pathologic behaviors), psychopathologic (Eating Disorder Inventory-2, Body Shape Questionnaire, Binge-Eating Scale, Beck Depression Inventory), personality (Temperament and Character Inventory), and clinical global impression measures. These measures were compared between the 2 treatment groups at baseline and at the end of treatment. Dropout rates were similar in the 2 groups. Both groups showed significant improvement in eating psychopathology, angry feelings, and clinical global impression. Patients in the fluoxetine group displayed a greater reduction in introjected anger, whereas those in the citalopram group displayed a greater reduction in depressive feelings. Both treatments showed some effect on outcome measures, but efficacy profiles did not overlap. Citalopram may be useful in depressed patients with bulimia, whereas fluoxetine is more specific for those with introjected anger and bulimia.

Abstract
Recent advances in obesity research focused on neuroendocrine control of food intake, appetite and body weight balance. Gut hormones, which are sequentially released from different regions of the gut, send signals to the areas of appetite control in the central nervous system causing a release of counter-regulatory hormones also originating from the gastrointestinal system. Ghrelin, a peptide secreted from the gastric fundus is released just before meal intake and stimulates hunger and food intake. Recently, peptide YY has been suggested to counteract ghrelin by inducing satiety and reducing appetite and caloric intake. While the effects of PYY on various gastrointestinal functions are well described, its action on weight loss is less known. Controversial results on the effect of exogenous administration of PYY(3-36) opened the discussion on the respective roles of PYY and/or PYY(3-36) in body weight homeostasis in man.

Abstract
Manual-based cognitive behavior therapy (CBT) is presently the most effective treatment of bulimia nervosa. Its efficacy is limited, however. Different strategies for improving upon current manual-based CBT are discussed, including combining CBT with antidepressant medication, integrating CBT with alternative psychological therapies, and expanding the scope and flexibility of manual-based CBT. CBT is underutilized in clinical practice. Dissemination of evidence-based treatment is a priority. Research on anorexia nervosa is minimal. Effective treatments have yet to be developed, although the Maudsley method of family therapy has shown the most promise in the treatment of adolescents. The most commonly seen eating disorders in clinical practice are those classified as "eating disorder not otherwise specified." With the exception of binge eating disorder (BED), however, they have been neglected by researchers. Several psychological therapies have been shown to be effective in treating BED. Controversy exists over whether treatment-specific effects have been identified. Whereas treatments have proved effective in eliminating binge eating and associated eating disorder psychopathology, achieving clinically significant weight loss remains a challenge.

Abstract
The purpose of this review is to discuss pharmacological options for the treatment of patients with eating disorders. Sequentially described are pharmacotherapy studies of anorexia nervosa (AN), bulimia nervosa (BN) and binge-eating disorder (BED). The quantity of drug trials performed with AN patients has been very limited. While the majority of studies have failed to show medication efficacy for the acute treatment of AN, there is data which suggests that fluoxetine hydrochloride may play a role in preventing relapse during maintenance therapy. Atypical antipsychotics, most often olanzapine, have shown promise in a number of uncontrolled studies. BN has been most extensively studied, with the majority of pharmacological trials focusing on antidepressants. Fluoxetine, at a dose of 60 mg/day, is FDA-approved for the treatment of BN. Psychotherapy, particularly cognitive behavioural therapy (CBT) is of well-established utility in BN and data suggests that the combination of an antidepressant plus CBT is superior to either treatment alone. Recently, there has been interest in the 5-HT3 antagonist, ondansetron, and the anticonvulsant, topiramate. BED investigators have focused largely on antidepressants, which may reduce symptoms of depression and augment psychotherapy. While sibutramine and topiramate have both been associated with weight loss in controlled trials, the former appears to be fairly well-tolerated and the latter appears to be responsible for the emergence of significant cognitive and peripheral nervous system side effects in some patients. Further pharmacological research with eating disorder patients is needed, particularly in the areas of AN and BED. Also, pharmacological augmentation strategies for those not responding to primary therapies should be explored.

Abstract
CONTEXT January, 2004, marked the publication of NICE guidelines for the treatment of eating disorders, a series of recommendations from a multidisciplinary, comprehensive, and rigorous process. The recommendations are assigned a grade from A (strong empirical support from well-conducted randomised trials) to C (expert opinion without strong empirical data). Over 100 recommendations were made, most of which were given a C grade. No specific recommendations were made for anorexia nervosa. Cognitive behavioural therapy for bulimia nervosa was assigned grade A because of the evidence showing that it is superior to other psychological and drug treatments. Antidepressants for bulimia nervosa were given grade B. No specific recommendations were made for atypical eating disorders except for binge-eating disorder (cognitive behavioural therapy was recommended [A]). STARTING POINT The methodological rigour of the NICE guidelines is in contrast with the current Practice Guideline for Eating Disorders (PGED) of the American Psychiatric Association. PGED does not detail criteria for evaluating supporting research. Instead of making clear recommendations, PGED is uncritically inclusive and emphasises subjective judgment of individual clinicians. The NICE guidelines balance recommending specific treatments against the importance of clinical judgment when guideline recommendations are not readily applicable. WHERE NEXT Evidence-based guidelines are limited by the quality of the available research and its clinical relevance. The NICE guidelines underscore the absence of sufficient evidence for guidance in several important areas, such as atypical eating disorders (eating disorders not otherwise specified) which are the most common. Research on the treatment of these atypical eating disorders is needed. Evidence-based psychological treatments are not routinely implemented in general practice. Dissemination of these demonstrably effective treatments poses a challenge, and learning how to implement evidence-based psychological treatments and monitor their use is a research priority.

Abstract
The pharmacological approach to bulimia nervosa is mainly based (BN) on selective serotonin reuptake inhibitors, but many elements suggest the possible involvement of the noradrenergic system in this disorder. The aim of the study was to assess the efficacy of reboxetine--a selective norepinephrine uptake inhibitor--in a sample of bulimic outpatients, after 3 months of treatment. Twenty-eight of 77 consecutively admitted patients with a DSM-IV diagnosis of BN (without Axis I comorbidity) received reboxetine. All patients were assessed at baseline (T0), and after 1 month (T1) and 3 months (T3), respectively, of treatment with reboxetine 4 mg/day. The subjects were administered the following questionnaires: Hamilton Rating Scale for Anxiety (HAM-A) and for Depression (HAM-D), Global Assessment Functioning (GAF), Eating Disorder Inventory-2 (EDI-2) and Body Shape Questionnaire (BSQ). Sixty percent of the patients were responsive to treatment(evaluated as a 50% decrease of bulimic behaviours). After 3 months of treatment, a significant reduction emerged in the scores of various EDI-2 subscales (Bulimia, Drive for Thinness, Body Dissatisfaction, Social Insecurity, Interpersonal Distrust, etc.) and in the BSQ total score. Moreover, depressive symptoms (HAM-D) and Global Functioning (GAF) scores showed a significant improvement. These data support a fast and favourable effect of reboxetine in the treatment of BN, both on symptoms and psychopathological features. Moreover, the specific and strong action of reboxetine on improvement of social functioning is also supported in this disorder.

Abstract
Tryptophan depleting protocols are commonly used to study the role of serotonin in mood disorders. The present study examined the impact of a tryptophan-deficient diet and fluoxetine on the serotonergic regulation of neuroendocrine function and body weight. We hypothesized that the regulation of postsynaptic 5-HT1Areceptors is dependent on the levels of 5-HT in the synapse. Rats on a control or a tryptophan-deficient diet received daily injections of saline or fluoxetine (5 or 10 mg·kg-1·day-1ip) from day 7 to day 21. The tryptophan-deficient diet produced a 41% reduction in the level of 5-HT but no change in the density of [3H]paroxetine-labeled 5-HT transporters. Treatment with fluoxetine inhibited the gain in weight in rats maintained on the control diet. The tryptophan-deficient diet produced a significant loss in body weight that was not significantly altered by treatment with fluoxetine. Treatment with fluoxetine produced a dose-dependent desensitization of hormone responses to injection of the 5-HT1Areceptor agonist (±)8-hydroxy-2-(di- n-propylamino)tetralin ((±)8-OH-DPAT). The tryptophan-deficient diet produced an increase in the basal levels of corticosterone but did not alter the basal levels of ACTH or oxytocin. Also, this diet inhibited the magnitude of 8-OH-DPAT-induced increase in plasma levels of ACTH and oxytocin but did not impair the ability of fluoxetine to desensitize the 5-HT1Areceptor-mediated increase in plasma hormones. These data suggest that a reserve of 5-HT enables fluoxetine to desensitize postsynaptic 5-HT1Areceptors in the hypothalamus. In conclusion, the profound physiological changes induced by tryptophan depletion may complicate the interpretation of studies using this experimental approach.

Abstract
BACKGROUND Bulimia nervosa and related syndromes such as binge eating disorder are common in young Western women. A specific manual-based form of cognitive behaviour therapy (CBT) has been developed for the treatment of bulimia nervosa (CBT-BN). Other psychotherapies, some from a different theoretical framework, and some modifications of CBT are also used. OBJECTIVES To evaluate the efficacy of CBT and CBT-BN and compare them with other psychotherapies in the treatment of adults with bulimia nervosa or related syndromes of recurrent binge eating. SEARCH STRATEGY A handsearch of The International Journal of Eating Disorders since its first issue; database searches of MEDLINE, EXTRAMED, EMBASE, PsycInfo, CURRENT CONTENTS, LILACS, SCISEARCH, CENTRAL and the The Cochrane Collaboration Depression, Anxiety & Neurosis Controlled Trials Register; citation list searching and personal approaches to authors were used. SELECTION CRITERIA All studies that have tested any form of psychotherapy for adults with non-purging bulimia nervosa, binge eating disorder and/or other types of eating disorders of a bulimic type (eating disorder, not otherwise specified, or EDNOS), and which applied a randomised controlled and standardised outcome methodology. DATA COLLECTION AND ANALYSIS Data were analysed using the Review Manager software program. Relative risks were calculated for binary outcome data. Standardized mean differences were calculated for continuous variable outcome data. A fixed effects model was used to analyse the data. Sensitivity analyses of a number of measures of trial quality were conducted. Data were not reported in such a way to permit subgroup analyses, but the effects of treatment on depressive symptoms, psychosocial and/or interpersonal functioning, general psychiatric symptoms and weight were examined where possible. Funnel plots were drawn to investigate the presence of publication bias. MAIN RESULTS The review supported the efficacy of cognitive-behavioural psychotherapy (CBT) and particularly CBT-BN in the treatment of people with bulimia nervosa and also (but less strongly due to the small number of trials) related eating disorder syndromes. CBT was also shown to be effective in group settings. Other psychotherapies were also efficacious, particularly interpersonal psychotherapy in the longer-term. Self-help approaches that used highly structured CBT treatment manuals, were promising albeit with more modest results generally, and their evaluation in bulimia nervosa merits further research. Exposure and Response Prevention did not appear to enhance the efficacy of CBT.Psychotherapy alone is unlikely to reduce or change body weight in people with bulimia nervosa or similar eating disorders. REVIEWERS' CONCLUSIONS There is a small body of evidence for the efficacy of cognitive-behaviour therapy in bulimia nervosa and similar syndromes, but the quality of trials is very variable and sample sizes are often small. More trials of CBT are needed, particularly for binge eating disorder and other EDNOS syndromes. Trials evaluating other psychotherapies and less intensive psychotherapies should also be conducted.

Abstract
Bulimia nervosa is a psychiatric condition that affects many adolescent and young adult women. The disorder is characterized by bingeing and purging behavior and can lead to medical complications. Thus, patients with bulimia nervosa commonly present in the primary care setting. Physical and laboratory examinations reveal markers of bulimia nervosa that are useful in making the diagnosis. Treatment is beneficial, and outcomes of early intervention are good. This article discusses the history, presentation, and tools needed for recognizing and treating bulimia nervosa in primary care.

Abstract
BACKGROUND To explore the personality, psychopathology, and clinical features of bulimic patients who do not complete psychotherapy, within a combined treatment. METHODS 86 patients with bulimia nervosa (BN; DSM-IV) were evaluated before beginning treatment. The Eating Disorder Inventory II (EDI-II), State-Trait Anger Expression Inventory (STAXI), and the Temperament and Character Inventory (TCI) were administered to all patients. RESULTS 3 subjects failed to engage in psychotherapy. Comparing patients who dropped out (n = 28) with those who did not drop out from psychotherapy (n = 55), significant differences were found in some psychopathologic (EDI-II, STAXI) and personality (TCI) variables. In particular, patients who dropped out from the treatment were more impulsive and more likely to feel anger; they were also less cooperative and less self-directive. No significant differences in sociodemographic, clinical variables and in response to fluoxetine were found between the two groups (dropout and completers). CONCLUSIONS We found a characteristic profile in the bulimic patients who dropped out from brief psychotherapy, i.e., they are less cooperative and more predisposed to anger. These data suggest that dropping out in a subgroup of BN patients could be related to borderline personality traits and to difficulties in making and maintaining a therapeutic relationship. Implications for treatment are discussed.

Abstract
Peptide YY (PYY) is the most potent orexigenic peptide or substance known. However, neither the underlying physiology of this hyperphagia nor PYY's natural role in brain are well understood. Thus, this review details the neuroanatomical sites, the neurochemical and systemic interactions, the food-related properties and the motivational factors that characterize hyperphagia elicited by central PYY. Emphasis also is given to evidence that central PYY has properties functionally distinct from neuropeptide Y. Finally, future research directions are outlined that aim at accelerating our understanding of the roles that brain PYY and PYY-preferring receptors occupy in normal and abnormal feeding behavior.
