Clinical epidemiology of eating disorders: results from the Sesto Fiorentino study.

BACKGROUND: It is speculated that clinical samples do not fully reflect the characteristics of eating disorders (EDs) as they are in the general population, especially in their lowest range of severity. The present article reports the prevalence of EDs in a community sample aged >14 years, their clinical and psychopathological features, and their course and outcome on naturalistic grounds. METHODS: The Sesto Fiorentino Study is a three-phase community-based survey where 2,355 out of 2,500 people representative of the population aged >14 years living in Sesto Fiorentino were evaluated by their own general practitioner using the Mini International Neuropsychiatric Interview plus six additional questions. All those who had positive results plus a probability sample of the non-cases were re-interviewed by psychiatrists using the Florence Psychiatric Interview. The subjects who reported ED symptoms were subsequently administered the Eating Disorder Examination (12th edition). RESULTS: Overall, the lifetime prevalence of EDs was 1.21%. More precisely, 0.42% had anorexia nervosa, 0.32% bulimia nervosa, 0.32% binge eating disorder and 0.32% eating disorder not otherwise specified. All the subjects suffering from an ED fulfilled diagnostic criteria for at least another DSM-IV axis I psychiatric disorder. At the moment of the interview, conducted a few years (average 7 years) after the onset of the disorder, 50% had fully recovered from EDs, 26.9% were currently affected by an ED, 23.1% showed a persistent body image disturbance and/or the presence of compensatory behaviours. CONCLUSIONS: Community surveys conducted by clinicians may provide useful additional information on the psychopathological features, natural course and outcome of these disorders on naturalistic grounds.

Eating disorders in patients with type 1 diabetes: a meta-analysis.

A meta-analysis of controlled studies on prevalence of eating disorders in Type 1 diabetes was performed in order to assess differences between diabetic and non-diabetic female subjects. All controlled studies using the Diagnostic and Statistical Manual of Mental Disorders Third Edition Revised (DSM Ill-R) or the DSM Fourth Edition (DSM IV) criteria for interview-based diagnosis were included in the analysis. The total sample was composed of 748 and 1587 female subjects with and without diabetes, respectively. The prevalence of anorexia nervosa (AN) in Type 1 diabetic subjects was not significantly different from that of controls (0.27 vs 0.06%), while that of bulimia nervosa and of the two conditions combined was significantly higher in diabetic patients (1.73 vs 0.69%, and 2.00 vs 0.75%, respectively; both p < 0.05). Type 1 diabetes is associated with a higher prevalence of bulimia nervosa in females.

The impotent couple: low desire.

Hypoactive sexual desire (HSD) is the deficiency of sexual fantasies and desire that should be considered as a disorder if it causes distress to the couple. In the general population, it is the most widespread sexuality-related problem. It is generally accepted that testosterone and prolactin regulate sexual desire. We recently reported that other psychobiological factors associate with HSD in a sample of almost 500 male patients attending our Outpatient Clinic for sexual dysfunction, by using SIEDY structured interview. We now originally extend investigation to a threefold broader patient sample. Considering marital parameters, perceived partner's libido and climax, patient's partner diseases, conflictual or even prolonged couple relationship were all significantly associated with an impairment of patients' sexual desire. Moreover, other lifestyle factors as satisfaction at work and/or domestic inhabitant relationship were significantly correlated to hypoactive sexual desire disorder (HSDD). Among hormonal parameters, severe hyperprolactinaemia (>700 mU/L), although rarely diagnosed (<2.0%), seems to play a greater role than the more common (23%) endocrine disease hypogonadism (testosterone < 12 nm) to the pathogenesis of HSD (RR = 7.5 [2.5-22.4] vs. 1.5 [1.1-1.9], respectively). Both mental disorders and use of medication interfering with sexual function were also significantly associated with HSDD, as well as depressive and anxiety symptoms. Finally, HSD was inversely correlated to sexual and masturbation frequency attempts. In conclusion, HSD is associated with several biological, psychological, and relational factors that can be simultaneously identified and quantified using the SIEDY structured interview.

Eosinophils, specific hyperreactivity and occurrence of late phase reaction in allergic rhinitis.

BACKGROUND: Eosinophil infiltration may be considered characteristic of nasal allergic inflammation. However, a mild inflammatory infiltrate may be present in asymptomatic subjects exposed to specific allergen. OBJECTIVE: We investigated the relationship between inflammation, specific hyperreactivity and clinical late phase reactions in allergic subjects using the ASNC model. METHODS: Sixty allergic subjects (aged from 18 to 47 years) were enrolled among those sensitized to pollens (n=20) and those to house dust mite with (n=20) or without (n=20) known clinical nasal LPR. All subjects were asymptomatic. TNSS and eosinophil number were assessed at baseline, 30 min (early phase) and 6 hours (late phase) after ASNC. RESULTS: Eosinophil number was higher in LPR+ rhinitics than in other groups, at baseline and during the early and late phase (p<0.001). ATD was lower in LPR+ rhinitics than in other groups (p<0.001). In LPR+ rhinitics, at baseline there was a significant correlation between eosinophils and ATD (r=0.56, p=0.009). After allergen challenge, TNSS was significantly higher in LPR+ rhinitics than in other groups, both during early and late phase (p<0.001 for all comparisons). CONCLUSIONS: In house dust mite sensitised subjects, LPR occurrence after allergen challenge is associated with higher inflammation and lower ATD at baseline. Therefore, in house dust mite allergy minimal persistent inflammation without symptoms can drive different clinical responses to allergen challenge.

The Eating Disorder Examination as a retrospective interview.

UNLABELLED: The purpose of this study was to determine the validity of the Eating Disorder Examination 12.0D (EDE) when administered retrospectively. METHODS: Twenty-five female patients suffering from an eating disorder [(10 with anorexia nervosa (AN), 10 with bulimia nervosa (BN), 5 with eating disorders not otherwise specified (EDNOS)] were investigated using the EDE at the time of the first referral to our outpatient ward (T1). Afterwards (mean 1.4 +/- 0.6 years later) each patient was administered again the EDE by the same assessor (T2). At this time the interviewer asked the patients to answer the questions referring to the symptoms and behaviours at the time of the first interview. RESULTS: Test-retest correlation factors were 0.7 or greater for all subscales of the EDE (p < 0.0001) and 0.5 or greater for every single item of the EDE (p < 0.001), except for EDE 1.5 (snack after dinner) and EDE 9A.6 (maximum time free from objective bulimic episodes in the last two months). DISCUSSION: Our results provide evidence that the EDE 12.0D is a reliable interview even when administered retrospectively, suggesting the use of this instrument for the retrospective assessment of eating disorders.

Cetirizine reduces cytokines and inflammatory cells in children with perennial allergic rhinitis.

Cetirizine has been demonstrated able of reducing nasal inflammatory infiltration in children with allergic rhinitis and cytokine production in in vitro studies. The aim of this double-blind, placebo-controlled, and randomized study was to evaluate cytokine pattern and inflammatory cells in children with perennial allergic rhinitis, before and after treatment with cetirizine or placebo. Twenty children with perennial allergic rhinitis were evaluated, 13 males and 7 females (mean age 13.4 years). Inflammatory cells and cytokines were evaluated by scraping and nasal lavage, before and after 2-weeks administration of cetirizine or placebo. IL4 and IL8 were measured by immunoassay and inflammatory cells were counted by conventional staining. Cetirizine treatment induced a significant decrease of IL4 (p<0.01) and IL8 levels (p=0.01). A significant reduction of the inflammatory cells was detected in actively-treated children, both concerning neutrophils and eosinophils (p<0.01). Moreover, cetirizine significantly reduced nasal obstruction score (p=0.007). This study shows the cetirizine effectiveness in exerting anti-inflammatory activity by modulating cytokine pattern and by reducing inflammatory infiltration in children with perennial allergic rhinitis.

Nasal eosinophils correlate with FEV1 in patients with perennial allergic rhinitis associated to asthma.

BACKGROUND: Eosinophil inflammation is present in nasal and bronchial mucosa and a clear link between upper and lower airways exists. Our aim was to evaluate whether nasal inflammation correlates with lung function in patients with perennial allergic rhinitis associated with asthma. METHODS: Eighty perennial allergic rhinitics with mild asthma, aged from 18 to 46 years, were enrolled. Nasal scraping and spirometry were performed in all subjects. RESULTS: A close relationship between the nasal eosinophil number and the percentage of predicted FEV1 was demonstrated (r = -0.76; p<0.0001). CONCLUSIONS Nasal cytology may be considered a non-invasive tool to assess airway inflammation in mild asthmatics with associated allergic rhinitis.

Adherence to structured physical exercise in overweight and obese subjects: a review of psychological models.

Regular physical exercise is a widely accepted means of reducing mortality and improving a number of health outcomes, which is also efficacious in the treatment of obesity. Unfortunately, despite the evidence of favourable short- and long-term effects, the results seem to be affected by a lack of adherence, particularly over the long term. It is very important to evaluate and predict good adherence in order to be able to assess the real efficacy of physical activity in the treatment of various diseases. In this paper, we describe most of the psychological models used to evaluate such adherence, and investigate the physiological and psychological bases of physical activity, the most suitable type of exercise for obese patients and some useful strategies for ensuring long-term adherence.

Nasal cytokine modulation by montelukast in allergic children: a pilot study.

BACKGROUND: Allergic rhinitis and asthma are characterized by chronic inflammation due to a Th2 cytokine polarization. Leukotrienes receptor antagonists have been shown to be effective in both diseases. OBJECTIVE: Aim of the study was to evaluate the modulation by the antileukotriene montelukast on Th2 and Th1 cytokines in allergic rhinitis. METHODS: Fourteen school children affected by persistent allergic rhinitis (PAR) and exercise-induced asthma (EIA) underwent a nasal lavage before and after a two-week treatment with montelukast. A panel of cytokines, including IL4, IL13, and IFN gamma, was measured by immunoassay on nasal lavage samples. RESULTS: Montelukast treatment induced a significant decrease of IL4 and IL13 levels (p < 0.001, for both comparisons), and a significant increase of IFN gamma (p < 0.001). CONCLUSIONS: Montelukast treatment reversed a typical Th2 cytokine pattern (IL4 and IL13) toward a Th1 (IFN gamma) predominance in children with PAR and EIA. This effect could be considered relevant for long term allergic inflammation control and of interest when treating EIA with concomitant PAR.

Eating behavior in obese patients with and without type 2 diabetes mellitus.

OBJECTIVE: Aim of this study was the assessment of the prevalence of eating disorders, and of eating disorder symptoms, in obese patients with type 2 diabetes, compared to non-diabetic subjects. DESIGN: Three samples of individuals were studied: a series of 156 (76 male, 80 female) overweight and obese type 2 diabetic patients, aged 30-65 y, with a body mass index (BMI)>28 kg/m(2) (DM); a series of 192 (20 male, 172 female) obese (BMI>30 kg/m(2)) non-diabetic patients aged 30-65 y seeking treatment for weight loss (OC); and a non-clinical sample of 48 (22 male, 26 female) obese (BMI>30 kg/m(2)) subjects aged 30-65 y selected from the lists of two general practices (OP). Eating behavior was assessed using the Eating Disorder Examination (EDE 12.0D). RESULTS: The prevalence of Binge Eating Disorder was lower than 5% in all the three samples. Median EDE scores in females were significantly higher in OC (3.0) and OP (3.4) than in DM (1.7), while diabetic patients showed higher scores on Restraint than both non-diabetic samples. Among diabetic patients, a significant correlation of EDE scores with HbA(1)c was observed. CONCLUSIONS: Type 2 diabetes is unlikely to induce relevant eating disturbances in obese patients, apart from an increase in restraint. Abnormalities of eating attitudes and behavior are associated with an impairment of metabolic control.

The 5-HT(2A) -1438G/A polymorphism in anorexia nervosa: a combined analysis of 316 trios from six European centres.

Several case-control association studies have raised the possibility that the A allele of a -1438 G/A polymorphism in the type 2A serotonin receptor (HTR2A) gene may be a risk factor for anorexia nervosa. However the absence of linkage and the existence of negative association studies raise the possibility of false positive findings, resulting from population stratification or lack of statistical power. To address this controversy we recruited a sample of 316 patients with anorexia nervosa from six European centres, and utilised a family-based transmission disequilibrium (TDT) approach to analyse the HTR2A-1438 G/A polymorphism. Age at onset and minimal BMI were also taken into consideration in order to detect clinical heterogeneity or a quantitative trait effect. The TDT approach showed that the A allele was transmitted 133 times and not transmitted 148 times (McNemar chi(2) = 0.29, df = 1, P = 0.59). Also, the haplotype-based haplotype relative risk method showed no evidence for association of the A allele, in samples from each centre (chi(2) < 2.15, df = 1, P > 0.14) and in the total sample (chi(2) = 0.55, df = 1; P = 0.46). Furthermore, we found no evidence for heterogeneity of the A allele frequency between samples (chi(2) = 2.54, df = 4, P = 0.64), either according to minimal-BMI (F1/242 = 2.14, P = 0.45) or age at onset (F1/224 = 2.39; P = 0.12). QTL-TDT analyses also showed no direct role of the A allele on these traits. We thus found no evidence for a significant role of the 5-HT(2A) gene in anorexia nervosa. Previous results may have been exposed to stratification bias (which we controlled by the TDT method) and/or the risk of type 1 error (from which we were less exposed because of the sample size).

The stepped-care approach in anorexia nervosa and bulimia nervosa: progress and problems.

The stepped-care approach is based on the assumption that treatment should be less intensive and hence less expensive and intrusive at the start. Current data suggest that cognitive behaviour therapy (CBT) should be the preferred first treatment for bulimia nervosa (BN) patients. By comparison with the numerous trials supporting its efficacy, in fact, the evidence sustaining similar therapies, e.g. interpersonal psychotherapy (IPT) or pharmacological therapy, is weaker. There are now sufficient data to justify the use of less intensive and shorter treatment (i.e. psychoeducational groups and self-help) in less serious cases. If CBT fails, IPT, pharmacological treatment, alternative psychotherapies, modified CBT, day-hospital and inpatient treatments are available, though it is not clear which is the most efficacious second step. The lower level of stepped-care models seems inapplicable in anorexia nervosa (AN). Current data do not suggest first-choice therapies. Management of this disorder is very expensive and requires a very high level of professional treatment and the highest level of the service hierarchy (intensive outpatient treatment, day-hospital, or inpatient treatment). One of the major obstacles to the employment of the stepped-care approach in eating disorders is that few therapists are trained in CBT and IPT. Academic structures and the scientific societies of eating disorders should promote training and dissemination of these effective forms of treatment.

Psychopathological and clinical features of outpatients with an eating disorder not otherwise specified.

In order to investigate similarities and differences between Eating Disorder Not Otherwise Specified (EDNOS) and Anorexia Nervosa (AN) and Bulimia Nervosa (BN), we studied a consecutive series of 189 female outpatients attending two Eating Disorder Units. The data were collected by means of interviews (Eating Disorder Examination, EDE 12.0D), the Structured Diagnostic Interview for DSM III-R, (SCID), and self-reported questionnaires (Beck Depression Inventory, BDI, and State and Trait Anxiety Inventory, STAI 1-2). The diagnosis of EDNOS was as frequent as that of AN and BN (43.8% versus 43.2%). There were no significant differences between EDNOS and AN/BN patients in terms of their general and specific psychopathological features, but significant differences were observed between bulimic-like and anorectic-like EDNOS patients, as well as between those with AN and BN. In conclusion, in our clinical setting, the patients with EDNOS and those with typical eating disorders have similar psychopathological features, thus suggesting that EDNOS patients should be further divided into two groups, anorectic-like (similar to AN) and bulimic-like (similar to BN) patients.

Anorexia nervosa and celiac disease: two case reports.

OBJECTIVE: Anorexia nervosa (AN) has been reported to be associated with several chronic medical illnesses. In this study, we report two cases of women suffering from AN and celiac disease. The former received the diagnosis of celiac disease before the onset of the eating disorder. For the latter, the diagnosis of celiac disease followed that of AN. Authors discuss the complex relationships between celiac disease and AN. They suggest that in the first case the dietary restriction could act as a trigger for the eating disorder, whereas in the second case, the onset of celiac disease could have exacerbated the clinical symptoms of AN.

Eating attitudes and behavior throughout the menstrual cycle in obese women: a case-control study.

Premenstrual variations of eating behavior are reported in several studies, but their relationship with mood is unclear. Eating behavior and physical and psychological complaints during the menstrual cycle were studied in 107 obese patients and 93 matched controls using retrospective (Weekly Bulimic Test Edinburgh, W-BITE and Premenstrual Assessment Form, PAF) and prospective (Daily Rating Form, DR) questionnaires. Eating disorder symptoms increased in the premenstrual phase, as shown by the W-BITE scores both in patients (6.2 +/- 5.3 premenstrual week vs 4.9 +/- 4.4 postmenstrual week, p < 0.05) and in control subjects (4.9 +/- 4.1 premenstrual week vs 4.2 +/- 3.0 postmenstrual week, p < 0.05) and were correlated to premenstrual complaints in control subjects (r = 0.5; p < 0.05) but not in obese women (r = 0.2; p = NS). A close relationship between physical and psychological premenstrual disturbances was observed in obese patients only. Premenstrual variation of eating behavior could be the target of specific treatment.

Minimal persistent inflammation is also present in patients with seasonal allergic rhinitis.

BACKGROUND: The allergic reaction is characterized by an inflammatory response, which is correlated to the allergen exposure, and is detectable in mite allergic patients, even when symptoms are absent. OBJECTIVE: The study was aimed at assessing the presence of inflammation in patients with pollen allergy during a long observation period. METHODS: Six patients, sensitized only to Betula alba, were enrolled. Evaluated parameters were (1) nasal symptoms, (2) inflammatory markers (ie, neutrophil and eosinophil number and intercellular adhesion molecule-1 expression on nasal epithelial cells), and (3) pollen count. Patients were examined during the pollen season every 4 days for 40 days and were observed 3 times after the pollen season. RESULTS: A significant inflammatory reaction was evident throughout the pollen season, even during the days with a low pollen count and low or absent symptoms. CONCLUSIONS: The results of this study indicate that the global therapeutic strategy for allergic rhinitis should be revised and targeted to inflammatory phenomena rather than to symptoms alone.

5-HT2A receptor gene polymorphisms in anorexia nervosa and bulimia nervosa.

To examine the distribution of different polymorphisms in genes of the 5-HT system in patients with anorexia nervosa (AN) and bulimia nervosa (BN), we analyzed the distribution of a polymorphism (-1438G/A) and the presence of known mutations in 5-HT2A and 5-HT2C receptor genes in 168 Italian female patients affected by AN and BN. Patients with AN restricting type (ANr) only, unlike those with AN binge eating/purging type (ANp) and BN purging type (BNp), showed a statistically significant difference in 5-HT2A-1438A/A genotype frequency with respect to controls. With regard to the other polymorphisms, no differences were found in the studied groups with respect to controls. 5-HT2A promoter polymorphism is probably implicated in the susceptibility to eating disorders and its involvement is more significant in ANr, when compared with ANp and BNp.

Failure of acupuncture in the treatment of obesity: a pilot study.

Acupuncture has been anecdotally reported to induce weight loss in obese patients. This pilot study examines its efficacy in a randomised, placebo-controlled clinical trial. Forty (33 F, 7 M) obese (BMI > 30 kg/m2) outpatients were randomised to either placebo or acupuncture (12 weekly sessions of minimal acupuncture and somatic moxibustion-acupuncture associated with auriculopuncture respectively). BMI, eating attitudes (BES), anxiety (STAI), depression (BDI), and obesity-related quality of life (ORWELL 97) were measured at the beginning and end of the treatment. Six (30%) patients in the treatment group and 12 (60%) in the placebo group dropped out. Intention-to-treat analysis did not show any significant effect of acupuncture on BMI and obesity-related quality of life; eating attitudes improved in both groups, possibly because of the placebo effect. A significant improvement in anxiety and depression was only observed in the acupuncture group. In conclusion, acupuncture does not promote weight loss and is not recommendable in the treatment of obesity. It may, however, improve the psychological status of obese patients.
