Söderqvist G, Naessén S. Androgens impact on psychopathological variables according to CPRS, and EDI 2 scores: In women with bulimia nervosa, and eating disorder not otherwise specified. J Steroid Biochem Mol Biol 2023; 226:106217. [PMID: 36368624 DOI: 10.1016/j.jsbmb.2022.106217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 10/28/2022] [Accepted: 11/06/2022] [Indexed: 11/09/2022]
Abstract
Bulimia nervosa (BN) is characterized by binge eating, compensatory behavior, over-evaluation of weight and shape, which often co-occur with symptoms of anxiety and depression. Depression is the most common comorbid diagnosis in women with eating disorders. The role of androgens in the pathophysiology of depression has been recognized in recent years. However, the research on psychopathological comorbidity and androgen levels in bulimic disease is sparse. This study aimed to investigate, if there were any correlations between the androgens, testosterone (T), dehydroepiandrosterone sulphate (DHEAS), androstenedione (A4), 5α-dihydrotestosterone, (5α-DHT), and test scores of psychopathological variables, in women with bulimia nervosa (BN), eating disorder not otherwise specified of purging subtype (EDNOS-P) assessed by CPRS, and EDI 2. Women with DSM-IV diagnosis of BN (n = 36), EDNOS-P (n = 27), and healthy control subjects (n = 58) evaluated for fifteen psychopathological variables, i.a. depressive symptoms, impulsivity, personal traits, as well as serum androgen levels. All women were euthyroid, and polycystic ovarian syndrome (PCOS) diagnosis was excluded. Although androgen levels were almost equal for all three groups, significant correlations between core psychopathological symptoms (9/15) of bulimia nervosa and the most potent endogenous androgen, 5α-DHT, was found only in the EDNOS-P group. The role of 5α-DHT in women is not fully elucidated. Both animal and human studies have shown that the brain is able to locally synthesize steroids de novo and is a target of steroid hormones. Maybe these results can be interpreted in the light of differences in androgen receptor variability, metabolism and origin of T and 5α-DHT.

Binge Eating Disorder-The Point Prevalence among Polish Women with Polycystic Ovary Syndrome and Validity of Screening Tool for This Population. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 20:546. [PMID: 36612867 PMCID: PMC9819692 DOI: 10.3390/ijerph20010546] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 12/19/2022] [Accepted: 12/23/2022] [Indexed: 06/17/2023]
Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders which is associated with an increased risk of metabolic dysregulation. The elevated prevalence of obesity has been observed in women with PCOS. Since obesity is commonly associated with eating disturbances, including the binge eating disorder (BED), and since the hormonal changes in PCOS patients could influence the food intake model, we decided to estimate the prevalence of BED in PCOS patients and to assess the sensitivity and specificity of the Questionnaire for Binge Eating Screening (QBES) in PCOS patients. METHODS A total of 122 hospitalized women with PCOS aged 16-45 (M = 26; SD = 5.22) took part in the study. Binge eating disorder (BED) was diagnosed according to the DSM-5 diagnostic criteria. QBES was used as a screening tool for BED. RESULTS The point prevalence of BED in PCOS women according to DMS-5 criteria was 51 (42%). At least two positive answers to four QBES items had 100% sensitivity and 91% specificity. Positive answers to even only the first two questions from QBES had 98% sensitivity and 85% specificity. CONCLUSIONS Women with polycystic ovary syndrome are at a very high risk of binge eating behaviors. Screening for eating disorders should be a routine procedure in women with PCOS. The first two questions from QBES are a brief and relatively reliable screening tool that may be used in everyday practice with POSC patients.

Abstract
BACKGROUND ED psychopathology is becoming more prevalent in Iran. Negative affect has been found to be an important risk factor in eating disorder (ED) onset in research conducted in Western countries, and is also emerging as a potential vulnerability factor to ED psychopathology in Iran. Network theory offers a novel framework to understand the association between negative affect and ED psychopathology in Iran. The primary aim of the current study was to use network analysis to identify bridge symptoms (i.e., symptoms that activate or weaken symptoms in another cluster) across a negative affect and ED psychopathology network among Iranian college students. We also aimed to identify core symptoms (i.e., nodes that demonstrate the strongest connections to other nodes). METHOD Participants were Iranian college students (n = 637; 60.3% women) who completed the Farsi-eating disorder examination-questionnaire and Farsi-negative affect. We estimated a network of ED symptoms and negative affective states and identified bridge and central symptoms. RESULTS Hostility and shame emerged as central bridge symptoms across the negative affect and ED psychopathology clusters. The most central nodes were strong desire to lose weight, definite fear of losing control over eating, and binge eating episodes. CONCLUSION The negative affective states of hostility and shame may increase vulnerability to ED psychopathology among Iranian college students. Findings have important implications for ED prevention programs that should be examined in future research.

Abstract
Borderline Personality Disorder (BPD) is a chronic debilitating psychiatric disorder characterized mainly by emotional instability, chaotic interpersonal relationships, cognitive disturbance (e.g., dissociation and suicidal thoughts) and maladaptive behaviors. BPD has a high rate of comorbidity with other mental disorders and a high burden on society. In this review, we focused on two compromised brain regions in BPD - the hypothalamus and the corticolimbic system, emphasizing the involvement and potential contribution of the endocannabinoid system (ECS) to improvement in symptoms and coping. The hypothalamus-regulated endocrine axes (hypothalamic pituitary - gonadal, thyroid & adrenal) have been found to be dysregulated in BPD. There is also substantial evidence for limbic system structural and functional changes in BPD, especially in the amygdala and hippocampus, including cortical regions within the corticolimbic system. Extensive expression of CB1 and CB2 receptors of the ECS has been found in limbic regions and the hypothalamus. This opens new windows of opportunity for treatment with cannabinoids such as cannabidiol (CBD) as no other pharmacological treatment has shown long-lasting improvement in the BPD population to date. This review aims to show the potential role of the ECS in BPD patients through their most affected brain regions, the hypothalamus and the corticolimbic system. The literature reviewed does not allow for general indications of treatment with CBD in BPD. However, there is enough knowledge to indicate a treatment ratio of a high level of CBD to a low level of THC. A randomized controlled trial investigating the efficacy of cannabinoid based treatments in BPD is warranted.

Abstract
Background: Growing evidences indicate that sex hormones have an effect on cognitive functions, and that Bulimia Nervosa (BN) is associated with cognitive impairment. The aim of this study was to determine the effect of hormonal contraception (HC) use on four cognitive functions that are impaired in patients with BN. Methods: This retrospective exploratory study included 103 women with a diagnosis of BN based on the DSM-5 criteria. Their age ranged from 15 to 45 years, and 46.6% were taking HC (oral, transdermal, or intrauterine). Cognition was assessed with the d2 test (attention), Iowa gambling task (IGT; decision making), Brixton spatial anticipation test (set shifting), and Rey-Osterrieth complex figure test (central coherence). Data were analyzed with logistic regression models to estimate the adjusted odds ratios (OR) and 95% confidence intervals (CI) of HC effect on the neuropsychological test scores. Results: In the multivariate model, HC use was significantly associated with better scores for two d2 test indices: F-score [OR = 0.98, 95% CI = (0.95; 0.99)] and final total score ratio [OR = 0.87, 95% CI = (0.77; 0.99)]. HC was also associated with a better understanding of the IGT explicit rules. No difference between the two groups (HC and non-HC use) was detected for set shifting and central coherence. Conclusions: This exploratory study suggests that HC could have effects on the sustained attention and concentration in women with BN. More studies are needed to confirm these results.

Abstract
Aggressive behavior exerts an enormous impact on society remaining among the main causes of worldwide premature death. Effective primary interventions, relying on predictive models of aggression that show adequate sensitivity and specificity are currently lacking. One strategy to increase the accuracy and precision of prediction would be to include biological data in the predictive models. Clearly, to be included in such models, biological markers should be reliably associated with the specific trait under study (i.e., diagnostic biomarkers). Aggression, however, is phenotypically highly heterogeneous, an element that has hindered the identification of reliable biomarkers. However, current research is trying to overcome these challenges by focusing on more homogenous aggression subtypes and/or by studying large sample size of aggressive individuals. Further advance is coming by bioinformatics approaches that are allowing the integration of inter-species biological data as well as the development of predictive algorithms able to discriminate subjects on the basis of the propensity toward aggressive behavior. In this review we first present a brief summary of the available evidence on neuroimaging of aggression. We will then treat extensively the data on genetic determinants, including those from hypothesis-free genome-wide association studies (GWAS) and candidate gene studies. Transcriptomic and neurochemical biomarkers will then be reviewed, and we will dedicate a section on the role of metabolomics in aggression. Finally, we will discuss how biomarkers can inform the development of new pharmacological tools as well as increase the efficacy of preventive strategies.

Abstract
We review the literature on aggression in women with an emphasis on laboratory experimentation and hormonal and brain mechanisms. Women tend to engage in more indirect forms of aggression (e.g., spreading rumors) than other types of aggression. In laboratory studies, women are less aggressive than men, but provocation attenuates this difference. In the real world, women are just as likely to aggress against their romantic partner as men are, but men cause more serious physical and psychological harm. A very small minority of women are also sexually violent. Women are susceptible to alcohol-related aggression, but this type of aggression may be limited to women high in trait aggression. Fear of being harmed is a robust inhibitor of direct aggression in women. There are too few studies and most are underpowered to detect unique neural mechanisms associated with aggression in women. Testosterone shows the same small, positive relationship with aggression in women as in men. The role of cortisol is unclear, although some evidence suggests that women who are high in testosterone and low in cortisol show heightened aggression. Under some circumstances, oxytocin may increase aggression by enhancing reactivity to provocation and simultaneously lowering perceptions of danger that normally inhibit many women from retaliating. There is some evidence that high levels of estradiol and progesterone are associated with low levels of aggression. We highlight that more gender-specific theory-driven hypothesis testing is needed with larger samples of women and aggression paradigms relevant to women.

Abstract
In nonhumans, the sex steroid testosterone regulates reproductive behaviors such as fighting between males and mating. In humans, correlational studies have linked testosterone with aggression and disorders associated with poor impulse control, but the neuropsychological processes at work are poorly understood. Building on a dual-process framework, we propose a mechanism underlying testosterone’s behavioral effects in humans: reduction in cognitive reflection. In the largest study of behavioral effects of testosterone administration to date, 243 men received either testosterone or placebo and took the Cognitive Reflection Test (CRT), which estimates the capacity to override incorrect intuitive judgments with deliberate correct responses. Testosterone administration reduced CRT scores. The effect remained after we controlled for age, mood, math skills, whether participants believed they had received the placebo or testosterone, and the effects of 14 additional hormones, and it held for each of the CRT questions in isolation. Our findings suggest a mechanism underlying testosterone’s diverse effects on humans’ judgments and decision making and provide novel, clear, and testable predictions.

Abstract
OBJECTIVE Clinical studies suggest comorbidity between eating disorders and aggressive behaviors. This study examined the pattern of comorbidity between intermittent explosive disorder (IED) and eating disorders (ED). METHODS Data were analyzed from both the adult and adolescent samples of the National Comorbidity Survey-Replication (n = 19,430) and a clinical research sample (n = 1,642). RESULTS Lifetime prevalence of Any ED was elevated in IED vs. non-IED for both the community and clinical research samples. Though anorexia nervosa displayed no relationship with IED in either sample, bulimia nervosa was associated with IED in the community sample and binge eating disorder was associated with IED in both the community and clinical research samples. Onset of IED preceded onset of Any ED in at least 70% of comorbid IED/ED cases in both community and clinical research samples. Associations of IED with Any ED and bulimia nervosa in the community sample, and associations of IED with binge eating disorder in the clinical research sample, remained significant after controlling for other psychiatric disorders. CONCLUSIONS Individuals with IED are more likely to report lifetime prevalence of ED, particularly bulimic spectrum disorders. This finding, and the observation that the onset of IED occurs prior to the onset of ED in the majority of individuals, suggests that longitudinal studies are needed to clarify this relationship and determine whether IED is a risk factor for the development of ED. Early identification of individuals with IED or impulsive aggression may provide clinically useful information to determine most effective treatment interventions.

Abstract
Polycystic ovary syndrome (PCOS) is an endocrine disorder affecting 5-15% of reproductive-aged women and characterized by high levels of circulating androgens. Given that androgens have been implicated in the aetiology of several psychiatric disorders, it was hypothesized that women with PCOS have high risk for psychiatric comorbidity. We aimed to investigate this risk amongst women with PCOS, as well as in their siblings, to elucidate if familial factors underlie any potential associations. Using the Swedish national registers, we identified all women diagnosed with PCOS between 1990 and 2013 (n=24,385), their full-siblings (n=25,921), plus matched individuals (1:10/100) from the general population and their full-siblings. Psychiatric disorder diagnoses were identified including schizophrenia, bipolar disorder, depressive and anxiety disorders, eating disorders, personality and gender identity disorder, autism spectrum disorder (ASD), attention-deficit hyperactivity disorder (ADHD), tics, attempted and completed suicide. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using conditional logistic regression and adjusted ORs (AOR) were determined by adjustment for comorbid psychiatric disorders. Overall, women with PCOS had an increased odds of having at least one psychiatric disorder (OR=1.56 [95CI%, 1.51-1.61]). Crude ORs showed associations with nearly all psychiatric disorders included in this study. Following adjustment for comorbid psychiatric disorders, women with PCOS were still at a significantly increased risk for bulimia, schizophrenia, bipolar disorder, depressive and anxiety disorders, personality disorders, with the highest AORs for ASD (AOR=1.55 [95%CI, 1.32-1.81]) and tics (AOR=1.65 [95%CI, 1.10-2.47]). Significantly higher AORs were found for ASD in both brothers and sisters of women with PCOS, and for depressive, anxiety, and schizophrenia spectrum disorders in the sisters only. Notably, the crude ORs for attempted suicide were 40% higher in women with PCOS and 16% higher in their unaffected sisters. However, the AORs were greatly attenuated indicating that underlying psychiatric comorbidity is important for this association. Women with PCOS had higher risks for a range of psychiatric disorders not shown before. Elevated risk in their siblings suggests shared familial factors between PCOS and psychiatric disorders. This study is an important first step towards identifying the underlying mechanisms for risk of psychiatric disorders in women with PCOS. Health professionals treating women with PCOS should be aware that these patients - as well as their family members - are important targets for mental health care.

Abstract
A number of studies have reported on dysfunctions in steroid secretion, including altered cortisol and testosterone levels in borderline personality disorder (BDP) patients compared to healthy controls. The present study extends findings from blood and saliva studies to the cumulative measure of hair steroids. We investigated women with BPD (n=18) and age- and education-matched healthy women (n=17). We did not find differences between BPD patients and healthy women (p=0.40) concerning hair cortisol levels but increased hair testosterone levels among BPD patients compared to controls (p=0.03). These results remained when restricting the analyses to unmedicated patients. Our data indicate altered long-term testosterone but not cortisol levels in females with BPD. Future studies should address the possible impact of altered testosterone on medical illness processes including metabolic syndrome in this population.

Abstract
Much remains to be understood about the etiology of eating disorders. There is substantial evidence that reproductive hormones, specifically estrogens, play a direct role in normal food intake. Evidence is increasing that the reproductive hormones play a role in the abnormal food intake associated with eating disorders. For example, there is an inverse association between estradiol and eating disorder symptoms. Preliminary studies also suggest that hormone augmentation may be a beneficial adjunct to the standard treatment of choice for eating disorders. However, research is limited, so definitive conclusions about the benefit of hormone augmentation in treatment cannot be drawn. Future research, with a focus on translational studies, should continue to explore the role of reproductive hormones in the vulnerability to and maintenance of eating disorders.

Kothari R, Gafton J, Treasure J, Micali N. 2D:4D ratio in children at familial high-risk for eating disorders: The role of prenatal testosterone exposure. Am J Hum Biol 2013; 26:176-82. [PMID: 24323736 PMCID: PMC3992907 DOI: 10.1002/ajhb.22495] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2013] [Revised: 11/13/2013] [Accepted: 11/25/2013] [Indexed: 11/05/2022] Open
Abstract
OBJECTIVES Markers of prenatal hormone exposure have been associated with the development of eating disorder (ED) behaviors. Our aim was to determine whether 2D:4D ratio, a marker for in utero testosterone exposure, is associated with risk for ED in a large population-based cohort: the Avon Longitudinal Study of Parents and Children (ALSPAC). METHODS This is the first study to investigate prenatal testosterone exposure in children at high-risk for ED, using 2D:4D as a marker. We compared children whose mothers reported a lifetime ED (anorexia, bulimia, or both; N = 446) to children whose mothers did not (n = 5,367). RESULTS Daughters of women with lifetime bulimia nervosa (BN) had lower 2D:4D ratio (B: -0.01, 95% CI: -0.02 to -0.002, P = 0.02), indicating higher prenatal testosterone exposure, than daughters of mothers unaffected by ED. No differences were observed in the male children of women with an ED. CONCLUSIONS Findings suggest that children at high-risk for BN may be exposed to higher levels of testosterone in utero. Fetal exposure to androgen excess is thought to be causal in the development of polycystic ovary syndrome (PCOS), a disorder which is highly comorbid with binge eating and BN. Future research should investigate the potential role of testosterone exposure in utero as a risk factor for BN and binge eating.

Abstract
To better understand how elevated androgen levels regulate food intake and obesity in females, we treated ovariectomized female mice with dihydrotestosterone (DHT) (non-aromatazable androgen), measured food intake and body weight, and evaluated physiological changes in liver function, glucose tolerance, and leptin resistance. Ovariectomized mice were treated with DHT or placebo. Mice were then fed a high fat diet under free-feeding or pair-feeding conditions for 3 months. We found that when DHT-treated ovariectomized mice had free access to food (free-feeding), they had increased food intake and higher body weight compared with control animals. These mice also had a significantly greater accumulation of fat in the liver and exhibited increased fasting glucose, impaired glucose tolerance, and resistance to leptin. However, when these mice were placed on a restricted diet and fed the same caloric amounts as controls (pair-feeding), their body weight increased at the same rate as control animals. This suggests that androgen regulates food intake through altered leptin sensitivity, and this increase of food intake could significantly contribute to an obesity phenotype. In summary, we demonstrated a role for androgen in the regulation of food intake and weight gain in females using a mouse model. This model will be useful to further elucidate the role of elevated androgen in females.

Abstract
This study examined the hypothesis that lower prenatal androgen exposure and earlier puberty are associated with more dysfunctional eating attitudes and behaviors. Relationships between both age at menarche (AAM) and 2D:4D (a marker of prenatal androgen exposure), and EDI-2-Body Dissatisfaction, EDI-2-Drive for Thinness, and EDI-2-Bulimia scores, were examined in women using correlations and regressions. Earlier menarche was associated with higher drive for thinness after controlling for BMI and negative affect, but only in women who were not exclusively heterosexual. Higher 2D:4D was associated with higher Bulimia and Body Dissatisfaction scores, but only in exclusively heterosexual women, and relationships disappeared when covariates were controlled. Later AAM and higher 2D:4D were unique predictors of higher Bulimia scores for exclusive heterosexuals when BMI was controlled. These findings suggest future research should examine sexual orientation as a mediator or moderator of prenatal and postnatal organizational hormonal effects on women's disordered eating attitudes and behaviors.

Abstract
OBJECTIVE This study examines the prevalence of overt and covert aggression in women with bulimia nervosa (BN) as well as the relationship between the severity of BN and the frequency of aggressive acts. PATIENTS AND METHODS 20 female college students with BN and 20 control subjects completed self-report measures of aggressive behavior and eating disorder pathology. They also completed the Juvenile Health and Wellness Survey-76 to assess general risk taking and indices of sexual behavior and mental health. RESULTS BN subjects reported higher levels of both overt and covert aggression (p < .001). Overt aggression tended to be more premeditated, while the self-report of covert aggression behavior was more impulsive. Levels of aggressive behavior were significantly correlated with severity of BN (p < .01). Subjects with BN reported higher levels of risk-taking and sexual behaviors. CONCLUSIONS Aggression is an important clinical issue in BN. Subtypes of aggression suggest different pathways for overt and covert aggressive acts with impulsive covert aggression being more closely related to the binge-purge cycle. Awareness of subtypes of aggression in BN may have important clinical and treatment implications.

Abstract
Obesity, increased visceral fat and disturbed glucose metabolism have been found in borderline personality disorder (BPD) patients. These conditions are often associated with disturbed androgen metabolism. Elevated androgens in women are related to polycystic ovaries (PCO) and might have an impact on psychopathology. Thus, higher prevalence of PCO and elevated androgen levels are suspected in BPD. In the study, we examined 31 BPD patients and 30 healthy controls ultrasonographically for PCO and measured their serum levels of androgens and interacting hormones. Furthermore, influence on psychopathology of free testosterone (FT) serum level was assessed. PCO was significantly more prevalent in BPD patients (30.4%) compared to healthy controls (6.9%). Testosterone, FT, androstenedione (A), and 17alpha-hydroxyprogesterone (17-OHP) were significantly elevated in the BPD group independently of BMI. FT serum level significantly correlated with depressive symptoms. In summary, our data suggest a disturbed androgen metabolism in BPD patients.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a common hyperandrogenic endocrine disorder affecting women of fertile age. The aim of this study was to survey whether the rate of clinical psychiatric disorders in PCOS differs from the normal population. METHOD Women with PCOS (n=49) meeting the Rotterdam criteria for PCOS, and 49 age-matched controls identified from the population registry, were recruited. Trained clinicians used the MINI International Neuropsychiatric Interview to establish lifetime occurrence of Axis I DSM diagnoses. Serum-testosterone and sex hormone binding globulin were analyzed. RESULTS Women with PCOS had higher lifetime incidence of depressive episodes, social phobia, and eating disorders than controls. Suicide attempts were seven times more common in the PCOS group than in the controls. Current as well as lifetime use of antidepressants and anxiolytic drugs were more common in the PCOS group. CONCLUSIONS Previous studies have found that PCOS is associated with decreased quality of life and self-rated mental symptoms. This study demonstrates that PCOS is also linked to psychiatric syndromes as verified by structured clinical assessments. The clinical implication of this study is that clinicians treating women with PCOS should be aware that these women are a high risk group for common affective and anxiety disorders as well as suicide attempts.

Abstract
OBJECTIVE Despite evidence of a link between the behavioral and cognitive dimensions of aggressiveness and eating disorders, only few studies have tested this relation empirically. METHODS A total of 112 female patients with anorexia nervosa (n = 61) or bulimia nervosa (n = 51) and 631 young girls attending 7 high schools in the same health district as the patients (northeast Italy) were invited to fill in a set of self-report instruments including the Eating Attitudes Test, the Bulimic Investigatory Test of Edinburgh, the Body Attitudes Test, and the Buss-Perry Aggression Questionnaire (AQ). RESULTS In both healthy controls and patients, scores on the measures of eating disorder symptoms were positively related to the scores on the AQ: the strength of the association did not differ between healthy controls and patients. However, patients diagnosed with eating disorders were not more likely to disclose a propensity to aggression than the healthy controls drawn from the community: patients with anorexia nervosa scored lower than controls on the physical aggression and on the verbal aggression subscales of the AQ (P < .05). On the other hand, patients with bulimia nervosa scored higher than controls on the anger subscale of the AQ (P < .05) but did not differ from them on the other subscales of the questionnaire. CONCLUSIONS The results confirm the higher propensity to anger in patients with bulimia nervosa; in patients with anorexia nervosa, difficulties in expressing anger and outward-directed aggressiveness can be a prevailing feature. The younger age of controls and exclusive reliance on self-report measures might have concealed some differences between patients and community subjects.

Abstract
The present small pilot study was designed to demonstrate the feasibility and relevance of using salivary assessments of biological markers to model a complex biological substrate of aggressive behavior. Five college-aged males completed the State-Trait Anger Expression Inventory on enrollment and provided saliva samples at 2000, 0200 and 0800 h during one mid-week 24-h period for three consecutive weeks. Saliva samples were assayed for cortisol (C), dehydroepiandrosterone (DHEA), and testosterone (T). All three biological measures showed stable circadian rhythms for each individual across the weeks of the study. Circadian variations indicate the importance, for C in particular, of including collection at 0200 h. Examination of the relationship among C, DHEA and T and the scales of the State-Trait Anger Expression Inventory provides preliminary evidence of an acceptable methodology to study complex interrelationships based on both levels and circadian variations of all three biological measures. This study demonstrates the feasibility of using salivary collection and assays to assess the level and stability of circadian variation in biological markers, and the necessity of formulating complex models to investigate the relationship between biology and behavior.

Abstract
High androgen levels in women with bulimia nervosa may promote bulimic behavior. The aim of the present study was to investigate the effects of an antiandrogenic oral contraceptive (OC) on appetite and eating behavior in women with bulimia nervosa compared to healthy controls. Twenty-one women with bulimia nervosa and 17 healthy controls matched for age and body mass index participated in the study. Basal and meal-related appetite and secretions of the satiety peptide cholecystokinin (CCK) and the appetite-stimulating peptide ghrelin were studied before and after 3 months of treatment with an antiandrogenic OC (30 microg ethinyl estradiol combined with 3 mg drospirenone). Bulimic behavior was evaluated in relation to changes in hormone levels. Before treatment, bulimic women had higher frequency of menstrual disturbances, acne and hirsutism and higher levels of testosterone but lower meal-related CCK secretion than controls. OC treatment reduced meal-related hunger and gastric distention in bulimics. CCK secretion in response to the meal was unchanged in bulimic women but decreased in the controls. Ghrelin secretion was comparable between groups and did not change in response to OC treatment. The treatment improved bulimic behavior in relation to a decline in testosterone levels in the entire group. Our results support the suggestion that androgens play a role in bulimic behavior. Treatment with an antiandrogenic OC may serve as a new strategy for treatment of bulimia nervosa and particularly in those patients with hyperandrogenic symptoms.

Abstract
Abstract. Numerous studies have investigated the relationship between testosterone (T) and aggression but yielded inconsistent findings in healthy subjects. One possible reason for this might be the measurement of actual T-levels, ignoring that its role in neurodevelopment seems to be of predominant importance. The aim of our study was to further elucidate the effects of T availability during early phases of gestation, operationalized by the measurement of the 2nd to 4th digit ratio (2D:4D), on behavioral aggression in healthy volunteers. A low 2D:4D (indicating a long ring finger relative to the index finger) relates to high levels of prenatal T. A total number of 171 healthy subjects (98 men, 73 women) ranging in age from 20 to 30 years were tested. Participants were subjected to a modified version of a competitive reaction-time task, a commonly used and well-established tool to elicit and measure aggression (Taylor paradigm). They also completed self-report scales on trait aggression. Ventral surface scans of both hands were used to determine the 2D:4D ratio. As expected, the 2D:4D was lower in men as compared to women for both hands. Moreover, in contrast to questionnaire data, men reveal higher levels of aggression in the computer task compared to women. Finally, a negative correlation between 2D:4D and aggression was found in males but not in females. Results are discussed with respect to the usefulness of the 2D:4D construct as well as to sex differences in organizational effects of T.

Abstract
Accumulating evidence has suggested that brain-derived neurotrophic factor (BDNF) plays a role in eating behaviours, and that BDNF-heterozygous (+/-) mice exhibit abnormal behaviours (e.g. obesity, anxiety and aggression). The present study was undertaken to determine whether or not dietary restriction (DR) alters the behaviours in BDNF(+/-) mice, as DR has been shown to exert a number of beneficial effects on the brain. Eight-week-old male wild-type (+/+) and BDNF(+/-) mice were divided into two groups, ad libitum (AL) diet group and DR group, for 16 weeks. After carrying out a behavioural evaluation, we determined the BDNF mRNA levels, as well as mRNA levels for subtypes (5-HT(1A), 5-HT(1B), 5-HT(2A) and 5-HT(2C)) of the 5-HT receptor and 5-HT transporter (5-HTT), protein levels of BDNF and concentrations of 5-HT and 5-HIAA in the hypothalamus, hippocampus and frontal cortex. DR significantly ameliorated behaviours including obesity, anxiety and aggression in BDNF(+/-) mice. The concentrations of 5-HT and 5-HIAA in the frontal cortex, and 5-HT in the hippocampus, of BDNF(+/-) mice were significantly lower than those of wild-type mice. Interestingly, DR significantly increased the levels of 5-HT and 5-HIAA in the frontal cortex of BDNF(+/-) mice. These findings suggest that DR may alter the behaviours in BDNF(+/-) mice, and that the 5-HT system may be implicated in the beneficial effects of DR on these behaviours.

Abstract
An association between bulimia nervosa and polycystic ovary syndrome (PCOS) has been suggested but also questioned. Since there is still a controversy about this issue, we investigated clinical and biochemical symptoms of PCOS according to the new diagnostic criteria in a large group of bulimic women compared with controls. Seventy-seven women with bulimia and 59 matched healthy women were investigated with respect to menstrual status, polycystic ovaries, hirsutism, acne and sex hormone levels. We found increased occurrence of menstrual disturbances, hirsutism and PCOS in bulimic women, whereas ovarian variables and acne did not differ from controls. Hirsutism score and indices of biologically active testosterone were positively correlated in bulimics but not in controls, while there were no major differences in serum androgens. In conclusion, this study supports an increased frequency of PCOS in bulimic women and may also indicate increased androgen sensitivity in these women. PCOS may promote bulimic behavior since androgens have appetite-stimulating effects and could impair impulse control. Menstrual disturbances and clinical signs of hyperandrogenism should be evaluated in bulimics in order to provide adequate medical care and treatment.

Abstract
Anorexia nervosa (AN), bulimia nervosa (BN) and binge eating disorder (BED) comprise the currently recognised eating disorders. Although distinct diagnostic entities, they share certain forms of comorbid psychopathology, particularly anxiety and mood disorders. BN and BED have been studied most intensively as targets for pharmacotherapy. The list of drugs tested in eating disorders is substantial; however, the number of therapeutic classes of medications tested in these conditions is relatively modest. Antidepressant medications, including tricyclic antidepressants, selective serotonin re-uptake inhibitors, as well as some of the novel antidepressants, have shown evidence of some therapeutic value in both BN and BED. Their efficacy in AN, however, has been disappointing. The pharmacological options for AN are very limited. The number of controlled trials that have been conducted is small, and the research that has been successfully completed has generally failed to demonstrate medication efficacy. Patients with BN typically show reduced binge eating and purging frequency in medication trials, but rarely attain abstinence. In BED, patients often measure the value of their medication therapy by its ability to stimulate weight loss, which is another area on which future pharmacotherapy may improve. Novel pharmacological interventions are needed for each of these conditions. Peptide hormones are increasingly being evaluated for eating disorder treatment, including ghrelin agonists, neuropeptide Y1 and -5 antagonists, orexin receptor antagonists, corticotropin-releasing factor receptor 2 antagonists, histamine 3 antagonists, melanocortin 4 receptor antagonists, beta3-adrenoceptor agonists, 5-hydroxytryptamine-2A antagonists and growth hormone agonists. Although these compounds are in early phases of clinical testing for eating disorder treatments, data from these studies will be instructive in the quest for effective pharmacotherapy for these conditions. An overview of the current pharmacotherapy options for eating disorders is presented with a discussion of the emerging potential treatments.

Abstract
Anger and aggressive behaviours, especially those self-directed, are frequent in subjects suffering from anorexia nervosa and bulimia nervosa. They increase the complexity of the clinical features, change the prognosis and cause a more difficult management of these disorders. In order to elucidate the complex relationships between eating disorders, anger and aggressiveness, the history of traumatic experiences, the prevalence of dissociative, obsessive, impulsive and compulsive symptoms, as well as the role of severe personality disorders in subjects suffering from anorexia nervosa, bulimia nervosa and self-injurious behaviours are considered. In the final section of this paper, a model exploring such a relationship in the light of the undefined sense of self is described.

Abstract
Prompted by previous studies suggesting that bulimia nervosa in women may be associated with elevated serum levels of testosterone, we have evaluated the possible effect of androgen antagonism in this condition. To this end, women meeting the DSM-IV criteria of bulimia nervosa, purging type, were treated in a one-center study with the androgen receptor antagonist flutamide (n = 9), the serotonin reuptake inhibitor citalopram (n = 15), flutamide plus citalopram (n = 10), or placebo (n = 12) for 3 months using a double-blind design. Self-rated global assessment of symptom intensity suggests all active treatments to be superior to placebo. The reduction in binge eating compared with baseline was statistically significant in both groups given flutamide but not in the groups given citalopram only or placebo. A moderate and reversible increase in serum transaminase levels led to discontinuation in two subjects in the flutamide group. It is concluded that blockade of androgen receptors may reduce some of the symptoms of bulimia nervosa in women.

Abstract
The association between alcohol and aggressive behavior is well established although a direct causal relationship has proven hard to demonstrate. There are, however, indications that alcohol facilitates aggression in individuals who already have a predisposition to behave aggressively. Aggressive personality disorders have in turn been explained by elevated testosterone level. A one-to-one relation between increased levels of testosterone and aggression has been, nevertheless, difficult to reveal. Two metabolites of testosterone, estradiol and 5alpha-dihydrotestosterone (DHT), have been studied much less in human aggressive behavior. Estradiol might reduce androgenic effects and have a counterbalancing influence on aggression. DHT, again, has a much higher affinity than testosterone to androgen receptors, and there are indications that some of the effects of testosterone-mediating aggressive behavior occur after aromatization. Disregard of seasonal and circadian fluctuations in male testosterone production might be responsible for some of the inconclusive testosterone-aggression results. In addition, increasing age decreases both aggressive behavior and testosterone production in males. Cortisol has yielded conflicting results as a mediator in aggressive behavior. Both higher and lower levels have been reported in aggressive and abusive men. Finally, the acute and chronic effects of alcohol influence the steroid hormone levels in various ways. The present understanding of the etiology of aggression is still vague. It is clear that a multidimensional approach, combining both biological and psychosocial factors, will be necessary for the development of a more general concept of human aggression in the future.

Abstract
Urinary steroid components were measured after enzyme hydrolysis and methoxym-silyl derivatization by capillary gas chromatography in young women with eating disorders. Using three internal standards, programmed temperature from 50 to 300 degrees C and flame ionization detection, on ULTRA-1 capillary column the separation of 28 steroid components is possible. Fifteen young women with different eating disorders, i.e. anorexia nervosa, bulimia nervosa and bulimarexia (aged 16-28 years) and 15 healthy women (aged 22-26 years) collected 24-h urine. A significant decrease of dehydroepiandrosterone (p<0.05) and a significant elevation of the stress marker allo-tetrahydrocorticosterone (p<0.05) were observed in the patients with compared to the controls. Among the patients two groups were defined due to a significant difference in the content of the cortisol metabolites compared to each other and to controls (p<0.01). The results confirm the role of dehydroepiandrosterone in eating disorders. The increased level of the stress marker allo-tetrahydrocorticosterone refers to the involvement of stress in these diseases, but the relevance of hormone alteration to the pathophysiology of eating disorders remains to be elucidated. The reason of the differences in cortisol metabolites levels in some patients needs further investigations.

Abstract
OBJECTIVE To study self-reported competencies and problems in adolescent girls with eating disorders, anorexia nervosa (AN), bulimia nervosa (BN), and eating disorder not otherwise specified (EDNOS) compared to matched normal controls. METHOD The Youth Self-Report (YSR) was completed by 211 girls between 13 and 17 years of age with eating disorders and 211 controls matched for age, sex, and geographical area. RESULTS Girls with eating disorders scored lower on all competence scales and higher on most problem 'scales compared to controls. Type of diagnosis had no effect on competence scales, but BN-patients scored higher than AN- and EDNOS-patients on many problem scales. AN-bingers/purgers reported more problems than restrictors on somatic complaints, delinquent behaviour, and the externalizing dimension. DISCUSSION We conclude that the YSR gives important information concerning self-reported competencies and concomitant symptoms of general psychopathology in eating disordered adolescent girls.

Abstract
OBJECTIVE To explore the links between propensity to aggression and eating disorders in a sample of school-aged adolescents in a northeastern area of Italy. METHOD In a mixed male-female sample of 1000 adolescents (10% of the district's population aged 15-19 years) we administered the Eating Attitudes Test, the Bulimic Investigatory Test of Edinburgh and the Body Attitudes Test, as measures of abnormal eating attitudes and behaviours, and the Aggression Questionnaire, as a measure of the propensity to aggression. RESULTS Females scored significantly higher than males at all eating disorders inventories (P < 0.0001). Males scored higher than females at the Aggression Questionnaire. In both genders, there was a positive correlation between scores at any of the eating disorders inventories and those at the Aggression Questionnaire (P < 0.0001). CONCLUSION Overtly expressed aggression might have a negative impact on the course of eating disorders and on the compliance with treatment, also enhancing the risk of suicide.
