Day-patient treatment after short inpatient care versus continued inpatient treatment in adolescents with anorexia nervosa (ANDI): a multicentre, randomised, open-label, non-inferiority trial

BACKGROUND In-patient treatment (IP) is the treatment setting of choice for moderately-to-severely ill adolescents with anorexia nervosa, but it is costly, and the risks of relapse and readmissions are high. Day patient treatment (DP) is less expensive and might avoid problems of relapse and readmission by easing the transition from hospital to home. We investigated the safety and efficacy of DP after short inpatient care compared with continued IP. METHODS For this multicentre, randomised, open-label, non-inferiority trial, we enrolled female patients (aged 11-18 years) with anorexia nervosa from six centres in Germany. Patients were eligible if they had a body-mass index (BMI) below the tenth percentile and it was their first admission to hospital for anorexia nervosa. We used a computer-generated randomisation sequence to randomly assign patients to continued IP or DP after 3 weeks of inpatient care (1:1; stratified for age and BMI at admission). The treatment programme and treatment intensity in both study groups were identical. The primary outcome was the increase in BMI between the time of admission and a 12-month follow-up adjusted for age and duration of illness (non-inferiority margin of 0·75 kg/m(2)). Analysis was done by modified intention to treat. This trial is registered with the International Standard Randomised Controlled Trial Number Register, number ISRCTN67783402, and the Deutsches Register Klinischer Studien, number DRKS00000101. FINDINGS Between Feb 2, 2007, to April 27, 2010, we screened 660 patients for eligibility, 172 of whom we randomly allocated to treatment: 85 to IP and 87 to DP. DP was non-inferior to IP with respect to the primary outcome, BMI at the 12-month follow-up (mean difference 0·46 kg/m(2) in favour of DP (95% CI, -0·11 to 1·02; pnon-inferiority<0·0001). The number of treatment-related serious adverse events was similar in both study groups (eight in the IP group, seven in the DP group). Three serious adverse events in the IP group and two in the DP group were related to suicidal ideation; one patient in the DP attempted suicide 3 months after she was discharged. INTERPRETATION DP after short inpatient care in adolescent patients with non-chronic anorexia nervosa seems no less effective than IP for weight restoration and maintenance during the first year after admission. Thus, DP might be a safe and less costly alternative to IP. Our results justify the broad implementation of this approach. FUNDING German Ministry for Education and Research.

Comorbid Psychiatric Disorders in Female Adolescents with First-Onset Anorexia Nervosa

OBJECTIVE Patients with anorexia nervosa (AN) exhibit high rates of psychiatric comorbidity. To disentangle the effects of duration of illness on comorbid psychiatric symptoms, we investigated the rates of comorbid psychiatric disorders, suicidality and self-harm behaviour in adolescent patients with a first onset of AN. METHODS In adolescent females (n = 148) with a first onset of AN, body mass index, psychiatric comorbidity (according to DSM-IV), depressive symptoms, suicidality and self-injurious behaviour were assessed. RESULTS Seventy patients (47.3%) met the criteria for at least one comorbid psychiatric disorder. The binge-purging subtype was associated with increased rates of psychiatric comorbidity, suicidality and self-injurious behaviour. The severity of eating disorder-specific psychopathology influenced current psychiatric comorbidity and suicidal ideation. CONCLUSION Prevalence rates of comorbid psychiatric disorders and suicidal ideation are considerably lower among adolescents with AN compared with adults. An early and careful assessment, along with adequate treatment of the eating disorder, might prevent the development of severe psychiatric comorbidities.

Morphological Changes in the Brain of Acutely Ill and Weight-Recovered Patients with Anorexia Nervosa

OBJECTIVE Acute anorexia nervosa (AN) leads to reduced gray (GM) and white matter (WM) volume in the brain, which however improves again upon restoration of weight. Yet little is known about the extent and clinical correlates of these brain changes, nor do we know much about the time-course and completeness of their recovery. METHODS We conducted a meta-analysis and a qualitative review of all magnetic resonance imaging studies involving volume analyses of the brain in both acute and recovered AN. RESULTS We identified structural neuroimaging studies with a total of 214 acute AN patients and 177 weight-recovered AN patients. In acute AN, GM was reduced by 5.6% and WM by 3.8% compared to healthy controls (HC). Short-term weight recovery 2-5 months after admission resulted in restitution of about half of the GM aberrations and almost full WM recovery. After 2-8 years of remission GM and WM were nearly normalized, and differences to HC (GM: -1.0%, WM: -0.7%) were no longer significant, although small residual changes could not be ruled out. In the qualitative review some studies found GM volume loss to be associated with cognitive deficits and clinical prognosis. CONCLUSIONS GM and WM were strongly reduced in acute AN. The completeness of brain volume rehabilitation remained equivocal.

Serum levels of S100B are decreased in chronic starvation and normalize with weight gain

S100B protein is mainly synthesized in glial cells and modulates the balance between cell proliferation and differentiation in neurons and glial cells. However, S100B is not CNS-specific since its production was detected in numerous non-cerebral tissues e.g. adipocytes. In this study we investigated the influence of chronic fasting and subsequent weight gain on serum levels of S100B in patients with anorexia nervosa. We found that nutritional status was an important factor influencing serum levels of S100B.

Growing Up Is Hard: Mental Disorders in Adolescence

BACKGROUND Puberty brings on many biological, mental, and social changes. In this phase of life, the prevalence of serious mental disorders is about 10%. METHODS This review is based on a selective search for publications on the prevalence, causes, risk factors, and effects of mental disorders in adolescence. RESULTS Internalizing mental disorders are more common in girls; these include depression, social anxiety, and eating disorders. Their prevalence ranges from 12% to 23%, depending on the particular diagnostic instruments and criteria that are applied. Disruptive disorders, e.g., disorders of social behavior, are more common in boys, with a worldwide prevalence of approximately 5% to 10%. Marked differences between the sexes appear during puberty. The one-year prevalence of self-injurious behavior is about 14% in boys and 25% in girls. The consumption of legal and illegal drugs is one of the risk-seeking behaviors associated with adolescence. CONCLUSION In routine check-ups and medical office visits, particular attention should be paid to the possibility of a mental disorder. Special outpatient clinics for adolescents can help more young people avail themselves of the existing preventive and therapeutic measures. Early diagnosis and treatment may prevent mental disorders in adulthood and foster age-appropriate development.

Neuropsychologische Befunde bei Anorexia und Bulimia nervosa im Kindes- und Jugendalter

Anorexia nervosa and Bulimia nervosa are common chronic psychiatric diseases afflicting in particular female adolescents. During the acute phase of starvation a number of hormonal, neuropsychological and cerebral morphological changes occur. Some of these abnormalities are only partly reversible. Psychiatric comorbidities complicate the clinical picture and aggravate appropriate therapeutic interventions. The following review describes in detail the neuropsychological impairments in eating disorders, potential factors influencing cognitive performance, and resulting implications for clinical every day life.

Motivation to change and perceptions of the admission process with respect to outcome in adolescent anorexia nervosa

BackgroundIn patients with anorexia nervosa (AN), there is evidence that readiness to change is an important predictor of outcome with respect to weight gain and improvement in eating disorder psychopathology. In particular, young patients are characterized by a low level of motivation for recovery and perceive more coercion at hospitalization. Thus, a better understanding of the variables that influence readiness to change and perception of the admission process in adolescent AN may help to support patients in initiating change and staying motivated for treatment.MethodsIn 40 adolescent patients diagnosed with AN according to DSM-IV criteria, we assessed in a prospective clinical cohort study the motivation to change using the Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ) at admission to inpatient treatment, in week 9 after admission and at discharge. Additional variables were assessed, including depressive symptoms (Beck Depression Inventory, BDI), eating disorder-specific psychopathology (Eating Disorder Inventory, EDI-2), body mass index (BMI) and the percentage of expected body weight (%EBW). The patients’ perceptions of the admission process and their perceived need for hospitalization were assessed using a self-report scale developed by Guarda et al. (2007).ResultsYounger patients perceived more coercion than older patients did. Low %EBW and more severe eating disorder-specific psychopathology were associated with a greater perceived need for hospitalization. Moreover, low %EBW at admission and a longer duration of illness were accompanied by a greater motivation to change at admission, whereas more severe eating disorder psychopathology was associated with a low motivation to change. The motivation to change increased significantly between admission and discharge. Patients with a greater motivation to change at admission exhibited a higher weekly weight gain during treatment but did not show better outcome in eating disorder-specific psychopathology and depression.ConclusionsMotivation to change is an important predictor of short-term outcome with respect to weight gain trajectory during treatment of adolescent AN. As patients with a higher BMI at admission and those with more severe eating disorder-specific symptoms seem to be less motivated to change, the crucial issue of motivation to change should be addressed with these patients during the therapeutic process.

Comparison of metabolic profiles of acutely ill and short-term weight recovered patients with anorexia nervosa reveals alterations of 33 out of 163 metabolites

Starvation represents an extreme physiological state and entails numerous endocrine and metabolic adaptations. The large-scale application of metabolomics to patients with acute anorexia nervosa (AN) should lead to the identification of state markers characteristic of starvation in general and of the starvation specifically associated with this eating disorder. Novel metabolomics technology has not yet been applied to this disorder. Using a targeted metabolomics approach, we analysed 163 metabolite concentrations in 29 patients with AN in the acute stage of starvation (T0) and after short-term weight recovery (T1). Of the 163 metabolites of the respective kit, 112 metabolites were quantified within restrictive quality control limits. We hypothesized that concentrations are different in patients in the acute stage of starvation (T0) and after weight gain (T1). Furthermore, we compared all 112 metabolite concentrations of patients at the two time points (T0, T1) with those of 16 age and gender matched healthy controls. Thirty-three of the metabolite serum levels were found significantly different between T0 and T1. At the acute stage of starvation (T0) serum concentrations of 90 metabolites differed significantly from those of healthy controls. Concentrations of controls mostly differed even more strongly from those of AN patients after short-term weight recovery than at the acute stage of starvation. We conclude that AN entails profound and longer lasting alterations of a large number of serum metabolites. Further studies are warranted to distinguish between state and trait related alterations and to establish diagnostic sensitivity and specificity of the thus altered metabolites.

Outcome of childhood anorexia nervosa—The results of a five‐ to ten‐year follow‐up study

OBJECTIVE Although admissions of children with anorexia nervosa (AN) are increasing, there remains a dearth of up-to-date knowledge of the course and outcome of early-onset AN. The aim of the present study was to investigate the outcomes of patients with AN onset before the age of 14. METHOD Sixty-eight consecutive former patients who met the DSM-IV criteria for AN and who had been treated at one of three German university hospitals were asked to participate in a follow-up study. Body mass index, body height, outcome of the eating disorder (ED), psychiatric morbidity, and health related quality of life (HRQoL) were assessed through a personal examination after an average time span of 7.5 years (range: 4.5-11.5 years) after admission. RESULTS One patient had died. Fifty-two subjects with a mean age of 12.5 (SD 1.0) years at admission and of 20.2 (SD 2.0) years at follow-up agreed to participate in the follow-up assessment, aggregating to 77.9% of the original sample. Approximately 41% of the participants had a good outcome, while 35% and 24% had intermediate and poor outcomes, respectively. Twenty-eight percent of the sample met the DSM-IV criteria for a current non-ED psychiatric disorder, and 64% met the criteria for a past non-ED psychiatric disorder. Mental HRQoL and ED-specific psychopathology was strongly associated with the outcome of AN. Average body height was below the normal range. A higher weight at admission was the only significant positive indicator of outcome. DISCUSSION Childhood AN is a serious disorder with an unfavorable course in many patients and high rates of chronicity and psychiatric comorbidity in young adulthood. Early detection and intervention are urgently needed.

First Sociodemographic, Pretreatment and Clinical Data from a German Web-Based Registry for Child and Adolescent Anorexia Nervosa

OBJECTIVE The first web-based registry for childhood and adolescent anorexia nervosa (AN) in Germany was established to systematically collect demographic and clinical data. These data as well as information on how young individuals with AN can find access to healthcare services are presented. METHOD Patients´ data from child and adolescent psychiatry departments of 12 university hospitals and two major nonuniversity hospitals in Germany were collected between January 2015 and December 2016. All patients met the ICD-10 diagnostic criteria for (atypical) AN. Sociodemographic data, type and amount of healthcare utilization before admission, and clinical data at admission and discharge were compiled. RESULTS 258 patients with a mean age of 14.7 years and a mean BMI at admission of 15.3 kg/m2 were included. The parents and patients had a higher educational level than the general German population. More than 80 % of the patients reported having utilized healthcare before hospitalization. The mean duration of outpatient treatment before hospitalization was 7 months. CONCLUSIONS There seem to be major barriers to specialist treatment for young patients with AN in Germany, which should be analyzed in future studies.
