Abstract
BACKGROUND Social dysfunction is a putative risk and maintaining factor for Eating Disorders (EDs). We assessed biological, emotional, and cognitive responses to a psychosocial stressor, in order to provide a multilevel investigation of the RDoC social process system in EDs. METHODS Patients were recruited among those seeking treatment for an ED. Cortisol response to Trier Social Stress Test (TSST) was measured in 105 subjects: 35 women with anorexia nervosa (AN), 32 with bulimia nervosa (BN) and 38 healthy women. Anxiety, hunger, and desire to eat throughout TSST were rated in a subgroup of them (23 AN, 21 BN, and 25 control women). Two-way ANOVAs with repeated measures were run to assess differences among groups. RESULTS The TSST-induced cortisol secretion of AN women was significantly higher than in BN and healthy women; this significance disappeared after controlling for body mass index. Compared to healthy women, both AN and BN women showed reduced cortisol reactivity that disappeared after controlling for trait anxiety and ineffectiveness. Both ED groups displayed increased anxiety response to TSST, while only AN group reported greater decreases in hunger and desire to eat. No significant correlations were found between cortisol and anxiety, hunger, or desire to eat in response to TSST. CONCLUSIONS People with EDs are characterized by blunted cortisol reactivity and greater anxiety, hunger, and desire to eat responses to a psychosocial stressor without any significant association between these measures. This study provides the first empirical and multilevel support to a deranged functioning of the RDoC "system for social process" in EDs.

Abstract
Depression is widely acknowledged to be a heterogeneous entity, and the need to further characterize the individual patient who has received this diagnosis in order to personalize the management plan has been repeatedly emphasized. However, the research evidence that should guide this personalization is at present fragmentary, and the selection of treatment is usually based on the clinician's and/or the patient's preference and on safety issues, in a trial-and-error fashion, paying little attention to the particular features of the specific case. This may be one of the reasons why the majority of patients with a diagnosis of depression do not achieve remission with the first treatment they receive. The predominant pessimism about the actual feasibility of the personalization of treatment of depression in routine clinical practice has recently been tempered by some secondary analyses of databases from clinical trials, using approaches such as individual patient data meta-analysis and machine learning, which indicate that some variables may indeed contribute to the identification of patients who are likely to respond differently to various antidepressant drugs or to antidepressant medication vs. specific psychotherapies. The need to develop decision support tools guiding the personalization of treatment of depression has been recently reaffirmed, and the point made that these tools should be developed through large observational studies using a comprehensive battery of self-report and clinical measures. The present paper aims to describe systematically the salient domains that should be considered in this effort to personalize depression treatment. For each domain, the available research evidence is summarized, and the relevant assessment instruments are reviewed, with special attention to their suitability for use in routine clinical practice, also in view of their possible inclusion in the above-mentioned comprehensive battery of measures. The main unmet needs that research should address in this area are emphasized. Where the available evidence allows providing the clinician with specific advice that can already be used today to make the management of depression more personalized, this advice is highlighted. Indeed, some sections of the paper, such as those on neurocognition and on physical comorbidities, indicate that the modern management of depression is becoming increasingly complex, with several components other than simply the choice of an antidepressant and/or a psychotherapy, some of which can already be reliably personalized.

Abstract
BACKGROUND In order to experimentally asses the role of socio-emotional problems in Eating Disorder (ED) psychopathology, we have measured affective states and ED-related attitudes in response to an acute psychosocial stress and their relationships with interpersonal sensitivity in people with Anorexia Nervosa (AN) and Bulimia Nervosa (BN). METHODS Twenty-one women with AN, 21 with BN and 27 healthy women underwent an acute psycho-social challenge, the Trier Social Stress Test. Anxiety feelings, hunger perception, amount of desired food and body dissatisfaction were measured throughout the experimental procedure. The relationships between these variables and with interpersonal sensitivity measures were explored through Pearson's correlation and mediation analyses. RESULTS Stress-induced anxiety was increased in people with EDs. People with AN showed reduced hunger perception, decreased desire for food and a negative association between anxiety feelings and desire for food. In people with EDs, baseline ineffectiveness predicted post-stress body dissatisfaction through the mediation of post-stress anxiety levels. LIMITATIONS The relatively low sample size and the lack of an experimental control condition are the main limitations of the study. CONCLUSIONS The present findings show, for the first time, the relationships between socio-emotional distress and ED-related attitudes in people with EDs, providing experimental support to the interpersonal model of EDs. This gives empirical evidence to treatments targeting interpersonal problems in EDs.

Abstract
BACKGROUND & AIMS We have recently reported specific fecal metabolomic changes in acute and short-term weight restored patients with anorexia nervosa (AN). In this study we explored the association between those metabolomic changes and patients' gut microbiome composition. METHODS The gut microbiome of AN women was sequenced in both the underweight phase (n = 21) and after short-term weight restoration (n = 16) and compared to that of 20 healthy women. According to a multi-omics approach, microbiome data were correlated with 49 relevant fecal metabolites previously characterized in our participants by an untargeted metabolomic procedure. RESULTS Compared to healthy women, AN patients showed a decreased intra-individual bacterial richness, an increased Bacteroidetes-to-Firmicutes abundance ratio and significant changes in the relative abundances of several bacteria at phylum, class, order, family and genus levels. These changes were observed in both the underweight and weight-restored condition. Moreover, the relationships among the 49 previously selected fecal metabolites and bacteria genera showed structures of different complexity among the 3 groups. In particular, a quarter of those relationships showed a divergent direction in the acutely ill patients with respect to the weight-restored ones or normal controls. Finally, in acutely ill patients 70% of those correlations showed a negative sign suggesting a prevalent metabolites consummation by gut microbiome. CONCLUSIONS These data confirm a profound perturbation in the gut microbiome composition of AN patients. Moreover, for the first time, they provide the evidence that in AN gut bacteria are connected with several fecal metabolites in a different way from normal controls and with divergent directions in the acute phase with respect to the weight-restored phase.

Abstract
PURPOSE Childhood trauma and parental bonding have been widely recognized as risk factors for eating disorders (EDs). However, their interplay in determining ED psychopathology has been poorly investigated. Consequently, we have assessed their interaction with core ED psychopathological symptoms. METHODS Fifty-seven patients with anorexia nervosa, 43 with bulimia nervosa and 77 healthy women completed the Childhood Trauma Questionnaire, the Parental Bonding Instrument and the Eating Disorder Inventory-2. Chi square test and regression analyses with a moderation model were performed to investigate the interplay between childhood trauma, parental bonding and ED symptoms such as ineffectiveness, social insecurity, drive to thinness, interoceptive awareness, impulsivity and perfectionism. RESULTS Compared to controls, patients with EDs showed higher levels of trauma and parental control perception and lower levels of parental care. Childhood maltreatment was more prevalent in patients with the affectionless control parental style. Moderation analyses revealed that higher maternal control significantly predicted the ED symptom of social insecurity only when participants experienced lower levels of emotional abuse. CONCLUSIONS These findings demonstrate an interplay between deranged problematic parental bonding and childhood trauma in promoting a possible vulnerability to social insecurity, one of the most central dimensions of ED psychopathology. This interaction might have psychotherapeutic implications. LEVEL OF EVIDENCE Level V, cross-sectional descriptive study.

Abstract
Background. Greater levels of insight may be linked with depressive symptoms among patients with schizophrenia, however, it would be useful to characterize this association at symptom-level, in order to inform research on interventions. Methods. Data on depressive symptoms (Calgary Depression Scale for Schizophrenia) and insight (G12 item from the Positive and Negative Syndrome Scale) were obtained from 921 community-dwelling, clinically-stable individuals with a DSM-IV diagnosis of schizophrenia, recruited in a nationwide multicenter study. Network analysis was used to explore the most relevant connections between insight and depressive symptoms, including potential confounders in the model (neurocognitive and social-cognitive functioning, positive, negative and disorganization symptoms, extrapyramidal symptoms, hostility, internalized stigma, and perceived discrimination). Bayesian network analysis was used to estimate a directed acyclic graph (DAG) while investigating the most likely direction of the putative causal association between insight and depression. Results. After adjusting for confounders, better levels of insight were associated with greater self-depreciation, pathological guilt, morning depression and suicidal ideation. No difference in global network structure was detected for socioeconomic status, service engagement or illness severity. The DAG confirmed the presence of an association between greater insight and self-depreciation, suggesting the more probable causal direction was from insight to depressive symptoms. Conclusions. In schizophrenia, better levels of insight may cause self-depreciation and, possibly, other depressive symptoms. Person-centered and narrative psychotherapeutic approaches may be particularly fit to improve patient insight without dampening self-esteem. Better insight seems associated with depressive symptoms in schizophrenia. Network analyses were used to explore this association in a large sample. Insight was associated with self-depreciation, guilt, and suicidal ideation. Although cross-sectional, data suggest causal direction from insight to depression.

Abstract
IntroductionThe use of coercive measures in clinical practice represents a common, but understudied problem in Europe. In 2002–2005, the European Commission funded the study “European Evaluation of coercion in psychiatry and harmonization of best clinical practice” (EUNOMIA), coordinated by the Department of Psychiatry of the University of Dresden and carried out in 12 European countries.ObjectivesThis study, carried out on the Italian EUNOMIA sample, aims to:1)assess the use of coercive measures in five Italian mental health inpatient units;2)identify the patients’ socio-demographic and clinical characteristics associated with the use of coercive measures;3)investigate the effect of coercive measures on the outcome of the patients.MethodsThe Italian sample included 294 admitted patients. Data were collected on coercive measures (physical restraint, seclusion and forced medication)ResultsAlmost 30% of the patients received coercive measures during their hospitalization; in particular, 22% received forced medication, 9% were restrained or fixed by mechanic devices, 7% were seclused. The most frequent reason for prescribing coercive measures was aggression against others. Patients who received coercive measures were more frequently male, with higher BPRS scores and a worse social functioning. At three months after discharge, they showed higher levels of positive symptoms, and reported more negative opinions on the need of hospital admission and on the appropriateness of psychiatric treatments.ConclusionsIn Italy coercive measures are in most of the cases applied to the patients affected by more severe psychopathology and disability.

Abstract
AbstractNumber and procedures of involuntary hospital admissions vary in Europe according to the different socio-cultural contexts. The European Commission has funded the EUNOMIA study in 12 European countries in order to develop European recommendations for good clinical practice in involuntary hospital admissions. The recommendations have been developed with the direct and active involvement of national leaders and key professionals, who worked out national recommendations, subsequently summarized into a European document, through the use of specific categories. The need for standardizing the involuntary hospital admission has been highlighted by all centers. In the final recommendations, it has been stressed the need to: providing information to patients about the reasons for hospitalization and its presumable duration; protecting patients’ rights during hospitalization; encouraging the involvement of family members; improving the communication between community and hospital teams; organizing meetings, seminars and focus-groups with users; developing training courses for involved professionals on the management of aggressive behaviors, clinical aspects of major mental disorders, the legal and administrative aspects of involuntary hospital admissions, on communication skills. The results showed the huge variation of involuntary hospital admissions in Europe and the importance of developing guidelines on this procedure.

Abstract
This chapter reviews the clinical presentation of bipolar I and bipolar II disorders, and in particular of manic, hypomanic, depressive, and mixed episodes. The DSM-5 operational criteria and the ICD-11 clinical descriptions and diagnostic guidelines are summarized, but several aspects that emerge from the literature and are not considered by those diagnostic systems are also covered. The divergences between those systems and the issues that remain controversial are pointed out, and the limitations of “specifiers” (or “qualifiers”) in accounting for the heterogeneity of depressive episodes are emphasized. Different clinical presentations of manic and depressive episodes in children and adolescents are also briefly described. It is concluded that the familiarity with the DSM-5 and/or the ICD-11 is not sufficient to ensure an appropriate approach to the diagnosis of mood episodes and disorders, in the absence of adequate training and clinical expertise.

Abstract
Improving real-life functioning is the main goal of the most advanced integrated treatment programs in people with schizophrenia. The Italian Network for Research on Psychoses previously explored, by using network analysis, the interplay among illness-related variables, personal resources, context-related factors and real-life functioning in a large sample of patients with schizophrenia. The same research network has now completed a 4-year follow-up of the original sample. In the present study, we used network analysis to test whether the pattern of relationships among all variables investigated at baseline was similar at follow-up. In addition, we compared the network structure of patients who were classified as recovered at follow-up versus those who did not recover. Six hundred eighteen subjects recruited at baseline could be assessed in the follow-up study. The network structure did not change significantly from baseline to follow-up, and the overall strength of the connections among variables increased slightly, but not significantly. Functional capacity and everyday life skills had a high betweenness and closeness in the network at follow-up, as they had at baseline, while psychopathological variables remained more peripheral. The network structure and connectivity of non-recovered patients were similar to those observed in the whole sample, but very different from those in recovered subjects, in which we found few connections only. These data strongly suggest that tightly coupled symptoms/dysfunctions tend to maintain each other's activation, contributing to poor outcome in schizophrenia. Early and integrated treatment plans, targeting variables with high centrality, might prevent the emergence of self-reinforcing networks of symptoms and dysfunctions in people with schizophrenia.

Abstract
An update of the chapter on Mental, Behavioral and Neurodevelopmental Disorders in the International Classification of Diseases and Related Health Problems (ICD) is of great interest around the world. The recent approval of the 11th Revision of the ICD (ICD-11) by the World Health Organization (WHO) raises broad questions about the status of nosology of mental disorders as a whole as well as more focused questions regarding changes to the diagnostic guidelines for specific conditions and the implications of these changes for practice and research. This Forum brings together a broad range of experts to reflect on key changes and controversies in the ICD-11 classification of mental disorders. Taken together, there is consensus that the WHO's focus on global applicability and clinical utility in developing the diagnostic guidelines for this chapter will maximize the likelihood that it will be adopted by mental health professionals and administrators. This focus is also expected to enhance the application of the guidelines in non-specialist settings and their usefulness for scaling up evidence-based interventions. The new mental disorders classification in ICD-11 and its accompanying diagnostic guidelines therefore represent an important, albeit iterative, advance for the field.

Abstract
In psychiatry, the information conveyed by diagnosis (i.e., the "type" to which the individual patient is reconducted) is in itself insufficient for therapeutic and prognostic purposes. Hence the need for a more detailed characterization of the individual case, with a special focus on the assessment of low-order and high-order psychopathological dimensions, the evaluation of the severity of the clinical picture, the assessment of the stage of development of the disorder, and the exploration of a series of antecedent and concomitant variables. We should start to promote the construction and validation of tools guiding the clinician systematically in this characterization, trying to incorporate in this effort elements of the approaches that are currently presented as "alternative" to the ICD and DSM.

Abstract
BACKGROUND To assess psychometric proprieties of the short version of TEMPS-M in an Italian clinical sample of patients with bipolar disorder type I (BDI), type II (BDI) or cyclothymic disorder (CYC). METHODS All participants were recruited in two Italian university sites. They were asked to complete the Italian version of the short TEMPS-M, consisting of 35 items on a five-point Likert scale ranging from 1 to 5. The factorial structure of the instrument was assessed by principal components analysis with varimax rotation. The reliability of the subscales was assessed with Cronbach's alpha. RESULTS The 815 recruited patients had a diagnosis of BDI (430), CYC (227) or BDII (158); 60% of them were female and with a mean age of 44.4 (±14.6) years. Cronbach's alpha coefficients of subscales ranged from 0.808 to 0.898. The factor analysis confirmed five dimensions (depressive, cyclothymic, hyperthymic, irritable, anxious), as in the English version of the scale. All temperaments were more represented in CYC than in BDI patients. Depressive and anxious temperaments were more represented in BDII than in BDI; the hyperthymic temperament was represented more in BDI than in BDII patients. LIMITATIONS No other assessment instrument was used as a reference to assess the external or predictive validity of TEMPS-M; several socio-demographic and clinical characteristics have not been assessed. CONCLUSION The Italian version of the short TEMPS-M shows good reliability and validity. It might be used in clinical and research settings, for the dimensional exploration of the investigated domains.

Abstract
Prior studies using exploratory factor analysis provide evidence that negative symptoms are best conceptualized as 2 dimensions reflecting diminished motivation and expression. However, the 2-dimensional model has yet to be evaluated using more complex mathematical techniques capable of testing structure. In the current study, network analysis was applied to evaluate the latent structure of negative symptoms using a community-detection algorithm. Two studies were conducted that included outpatients with schizophrenia (SZ; Study 1: n = 201; Study 2: n = 912) who were rated on the Brief Negative Symptom Scale (BNSS). In both studies, network analysis indicated that the 13 BNSS items divided into 6 negative symptom domains consisting of anhedonia, avolition, asociality, blunted affect, alogia, and lack of normal distress. Separation of these domains was statistically significant with reference to a null model of randomized networks. There has been a recent trend toward conceptualizing the latent structure of negative symptoms in relation to 2 distinct dimensions reflecting diminished expression and motivation. However, the current results obtained using network analysis suggest that the 2-dimensional conceptualization is not complex enough to capture the nature of the negative symptom construct. Similar to recent confirmatory factor analysis studies, network analysis revealed that the latent structure of negative symptom is best conceptualized in relation to the 5 domains identified in the 2005 National Institute of Mental Health consensus development conference (anhedonia, avolition, asociality, blunted affect, and alogia) and potentially a sixth domain consisting of lack of normal distress. Findings have implications for identifying pathophysiological mechanisms and targeted treatments.

Abstract
Characterized primarily by a low body-mass index, anorexia nervosa is a complex and serious illness1, affecting 0.9-4% of women and 0.3% of men2-4, with twin-based heritability estimates of 50-60%5. Mortality rates are higher than those in other psychiatric disorders6, and outcomes are unacceptably poor7. Here we combine data from the Anorexia Nervosa Genetics Initiative (ANGI)8,9 and the Eating Disorders Working Group of the Psychiatric Genomics Consortium (PGC-ED) and conduct a genome-wide association study of 16,992 cases of anorexia nervosa and 55,525 controls, identifying eight significant loci. The genetic architecture of anorexia nervosa mirrors its clinical presentation, showing significant genetic correlations with psychiatric disorders, physical activity, and metabolic (including glycemic), lipid and anthropometric traits, independent of the effects of common variants associated with body-mass index. These results further encourage a reconceptualization of anorexia nervosa as a metabo-psychiatric disorder. Elucidating the metabolic component is a critical direction for future research, and paying attention to both psychiatric and metabolic components may be key to improving outcomes.

Abstract
OBJECTIVE The interplay among personality traits, anxiety and eating symptoms in candidates for bariatric surgery has never been investigated through the network analysis approach. Thus, we aimed to use this method to identify the key psychological traits that characterize these individuals and to assess their role as predictors of surgical outcomes. METHODS One-hundred-eighty-five candidates for bariatric surgery filled in the State Trait Anxiety Inventory (STAI), the Revised Restraint Scale, the Power of Food Scale and the Temperament and Character Inventory-Revised (TCI-R) questionnaires. All these variables were included in a network analysis. Then, the most central network nodes were entered as independent variables in a regression model that included 9-month follow-up weight outcomes as the dependent variable. RESULTS The network has showed a good stability. TCI-self directedness and harm avoidance scores and STAI state and trait anxiety scores were the nodes with the highest centrality in the network. Weight outcomes were assessed in 64 patients at follow-up. Among central nodes, low TCI-self directedness was found to be the only significant independent predictor of worse weight outcome. CONCLUSIONS Our findings show for the first time the interplay between personality traits and symptoms in candidates for bariatric surgery combining the network approach with a follow-up evaluation. Low self-directedness has been proved to be the node with highest centrality and the only predictor of short-term weight outcome. These data suggest the importance to take into consideration personality and psychological variables either in the pre-surgery assessment or as possible targets for pre or post-surgery psychotherapeutic interventions.

Abstract
Objectives: Childhood maltreatment is a non-specific risk factor for eating disorders (EDs). However, so far, no study has assessed the impact of childhood maltreatment on brain structure of adults with EDs. Therefore, we investigated brain area volumes and fibre tract integrity of childhood maltreated (Mal) and non-maltreated (noMal) patients with EDs. Methods: Thirty-six ED women and 16 healthy women underwent an MRI scan, including acquisition of a diffusion tensor imaging (DTI) sequence and a high-resolution T1-weighted scan. ED participants were classified as Mal (18 patients) or noMal (18 patients) according to their childhood exposure to traumatic events assessed by the Childhood Trauma Questionnaire (CTQ). Results: Significantly reduced grey matter volume was detected in the right paracentral lobule and in the left inferior temporal gyrus of Mal patients. DTI analyses revealed reduced white matter integrity in the corpus callosum, internal capsule, posterior thalamic radiation, longitudinal fasciculus and corona radiata of Mal patients. Negative correlations emerged between white/grey matter changes and CTQ emotional and physical neglect scores. Conclusions: These results show that childhood trauma affects the integrity of brain structures modulating brain processes, such as reward, taste and body image perception, which play a fundamental role in the psychopathology of EDs.

Abstract
Background: The patients' appraisal, satisfaction and attitude toward research is crucial to obtain reliable information, in psychiatry frequently not objective.Aim: We operationalised the information derived from studies on satisfaction and attitude towards research and developed a standardized measure, whose internal consistency and factor structure was investigated.Method: The Questionnaire on Attitude towards Research and health Care (QuARC) is a 10-item self-report scale, administered to 116 patients with psychotic disorders participating in research protocols. Exploratory factor analysis was conducted and internal consistency evaluated.Results: Two factors have been identified: one labelled External Factor, including items related to information on the received treatment, relationship with third parties, and one labelled Internal Factor with items related to the disorder, perceived well-being and contribution to scientific knowledge. Cronbach's alpha internal consistencies were good.Conclusions: The QuARC is easy to use, well accepted, with good psychometric properties. The constructs identified are different from the original issues addressed (i.e. attitude and satisfaction), prevailing different constructs closer to the patient opinion on the research and personal condition. These constructs identify dimensions useful to delineate and understand the patients' experience of participating in a scientific project as well as their satisfaction.

Abstract
Two hundred forty six patients with eating disorders (EDs) recruited from eight Italian specialized treatment centres were administered with the World Health Organization "Encounter Form," a standardized schedule that makes it possible to characterize the clinical pathways that patients follow to reach specialized care. The median time from symptoms onset to specialized care was 114 weeks. Primary "points of access to care" were general practitioners (25%), psychiatrists (18%), and clinical nutritionists (17%), followed by various other carers. All patients received specific psychotherapy, whereas only 11% of them were given psychotropic drugs. EDs are characterized by complex care pathways, with low rates of direct access to specialized care. Although the role of general practitioners remains crucial, they tend to follow different clinical routes to refer ED patients. Educational programmes on EDs should be addressed to general practitioners and clinical nutritionists, in order to ease the transition of ED patients to a mental health care setting.

Abstract
OBJECTIVE Negative symptoms are currently viewed as having a 2-dimensional structure, with factors reflecting diminished expression (EXP) and motivation and pleasure (MAP). However, several factor-analytic studies suggest that the consensus around a 2-dimensional model is premature. The current study investigated and cross-culturally validated the factorial structure of BNSS-rated negative symptoms across a range of cultures and languages. METHOD Participants included individuals diagnosed with a psychotic disorder who had been rated on the Brief Negative Symptom Scale (BNSS) from 5 cross-cultural samples, with a total N = 1691. First, exploratory factor analysis was used to extract up to 6 factors from the data. Next, confirmatory factor analysis evaluated the fit of 5 models: (1) a 1-factor model, 2) a 2-factor model with factors of MAP and EXP, 3) a 3-factor model with inner world, external, and alogia factors; 4) a 5-factor model with separate factors for blunted affect, alogia, anhedonia, avolition, and asociality, and 5) a hierarchical model with 2 second-order factors reflecting EXP and MAP, as well as 5 first-order factors reflecting the 5 aforementioned domains. RESULTS Models with 4 factors or less were mediocre fits to the data. The 5-factor, 6-factor, and the hierarchical second-order 5-factor models provided excellent fit with an edge to the 5-factor model. The 5-factor structure demonstrated invariance across study samples. CONCLUSIONS Findings support the validity of the 5-factor structure of BNSS-rated negative symptoms across diverse cultures and languages. These findings have important implications for the diagnosis, assessment, and treatment of negative symptoms.

Abstract
BACKGROUND Metabolic dysfunctions in patients with bipolar disorder (BD) are critical factors that interfere with outcome, but only one study evaluated the influence of glucose dysmetabolism on the response to treatment with lithium. We aimed to investigate the potential impact of glucose metabolic status on clinical characteristics of BD patients and their response to treatment with different mood stabilizers in monotherapy or in combination. METHODS 45 BD patients with insulin resistance (IR) or type 2 diabetes mellitus (DM2) and 46 patients with normal glucose metabolism, treated with mood stabilizers for at least one year were assessed by diagnostic and rating instruments. Their clinical characteristics were compared and an ordinal logistic regression model was adopted to identify possible predictors of response to mood stabilizer treatments. RESULTS Compared to patients with normal glucose metabolism, BD patients with impaired glucose metabolism showed a worse clinical presentation of their psychiatric illness and a worse response to mood stabilizers. Ordinal logistic regression analysis evidenced that impaired glucose metabolism was the only predictor of poor response to mood stabilizers (OR 4.3; 95% CI: 1.7-11.1; p < 0.002). LIMITATIONS Cross-sectional design and the relatively small sample size, are the main limitations of our study. CONCLUSIONS Our findings expand literature data suggesting that BD patients with impaired glucose metabolism are at a greater risk of not responding to lithium as well as to different mood stabilizer treatments.
