Background
The use of valproate in the treatment of Anorexia Nervosa (AN) in children and adolescents is currently not recommended by clinical guidelines, due to lack of evidence. Nonetheless, ...valproate is used to treat a series of psychiatric and neurologic conditions. To date, only six cases of patients with Feeding and Eating Disorders (three with AN) have been described.
Methods
Case series of 14 children and adolescent patients hospitalized for AN and treated with valproate as an adjunctive treatment. Reasons for introduction, dosages, plasma levels, adverse drug reactions (ADR) and modifications of liver enzymes, platelets levels, abdominal and pelvic ultrasounds, and concurrent drugs plasma levels were assessed.
Results
Reasons for the introduction of valproate included unstable mood (57.1%), lack of compliance (50%) and aggressive behaviour (21.4%). In 71.4% of patients an improvement on target symptoms was observed. Valproate was started at 241.7 (± 73.3) mg, up to 521.4 (± 204.5) mg; the most frequent scheme was twice-daily. The mean plasmatic concentration was 66.3 (± 25.0) mg/L. One patient (7.1%) experienced side effects (somnolence). No major modifications of liver enzymes, platelet levels, abdominal and pelvic ultrasounds emerged after the introduction of valproate. Low concurrent olanzapine and quetiapine levels were documented.
Conclusions
This is the largest sample of patients with AN treated with valproate. Valproate was administered to improve psychiatric symptoms impairing compliance with inpatient treatment programs. The majority of patients experienced an improvement on target symptoms after being administered valproate, with minor ADR. These data should be investigated in wider populations and controlled studies.
Level of evidence
Level IV, case series.
Background:
Current Diagnostic and Statistical Manual of Mental Disorders (DSM)-5-based research provides limited data on the use of risperidone on children and adolescents with anorexia nervosa (AN) ...mainly in small-sample/case report studies.
Aim:
To report the use of risperidone in a group of children and adolescents with feeding and eating disorders, specifically with AN.
Methods:
Observational, naturalistic study. Psychopathology was assessed with Eating Disorders Inventory-3, Beck’s Depression Inventory-II, and Symptom Checklist-90-R. Data were reported for the whole sample, for patients treated with risperidone, and finally compared between patients with AN treated with risperidone and those receiving no atypical antipsychotics. Potential differences in admission–discharge changes in body mass index (BMI) and psychopathology were assessed with analyses of covariance corrected for baseline measures. Kaplan–Meier analyses were conducted to assess retention rates of risperidone (at 3 months and 1 year) and rates of rehospitalization on 1-year follow-up.
Results:
The study enrolled 120 patients with AN (42 treated with risperidone). Risperidone was used for 116.7 (±122.8) days (total exposure = 3979 days) and well-tolerated (nausea, asthenia in one case). No significantly different admission–discharge improvements for BMI or psychopathology were documented for patients treated with risperidone. Risperidone showed a 3-month retention rate of 50.0% (1 year: 9.5%) and was discontinued mainly for the resolution of target symptoms. Cumulative freedom from rehospitalization at 12 months was comparable for treated and untreated patients (hazard ratio = 1.088; Log-rank p = 0.908).
Conclusions:
This study reports real-life evidence of the use of risperidone in AN children and adolescents in the widest described sample so far. Longitudinal research should assess long-term prognostic factors and tolerability.
Noradrenaline (NE) is a catecholamine acting as both a neurotransmitter and a hormone, with relevant effects in modulating feeding behavior and satiety. Several studies have assessed the relationship ...between the noradrenergic system and Eating Disorders (EDs). This systematic review aims to report the existing literature on the role of the noradrenergic system in the development and treatment of EDs. A total of 35 studies were included. Preclinical studies demonstrated an involvement of the noradrenergic pathways in binge-like behaviors. Genetic studies on polymorphisms in genes coding for NE transporters and regulating enzymes have shown conflicting evidence. Clinical studies have reported non-unanimous evidence for the existence of absolute alterations in plasma NE values in patients with Anorexia Nervosa (AN) and Bulimia Nervosa (BN). Pharmacological studies have documented the efficacy of noradrenaline-modulating therapies in the treatment of BN and Binge Eating Disorder (BED). Insufficient evidence was found concerning the noradrenergic-mediated genetics of BED and BN, and psychopharmacological treatments targeting the noradrenergic system in AN. According to these data, further studies are required to expand the existing knowledge on the noradrenergic system as a potential target for treatments of EDs.
Background: Various mental health and eating behavior variables have been independently associated with predicting weight loss in individuals with obesity. This study aims to investigate a mediation ...model that assesses the distinct contributions of these variables in predicting weight changes in patients with obesity following an outpatient behavioral weight loss intervention (BWLI). Methods: General mental health (depression, anxiety, stress, impulsivity), eating behavior (cognitive restraint, disinhibition, hunger), eating disorder pathology, and body mass index (BMI) were assessed in a group of 297 patients with obesity at the admission of a BWLI program. BMI was re-evaluated during the final treatment session. A mediation model was employed to examine whether mental health and eating behavior variables predicted BMI changes, with eating disorder pathology serving as a mediator. The model was tested both overall and within two patient subgroups: those with regular binge eating (≥four episodes/month) and those without. Results: In the overall sample (n = 238), the relationships between depression, impulsivity, and cognitive restraint with BMI change were mediated by eating disorder pathology. In the subgroup with regular binge eating (n = 99, 41.6%), the associations between stress and disinhibition with BMI change were additionally mediated by eating disorder pathology. In the subgroup without regular binge eating, eating disorder pathology showed no mediating effect. Discussion: Multiple mental health and eating behavior variables assessed at admission predicted BMI changes, particularly when mediated by eating disorder pathology in patients with regular binge eating. A comprehensive psychopathological assessment prior to starting BWLI may help identify multiple factors affecting prognosis and treatment outcomes. Long-term follow-up studies in this field are required.
The Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) defines echolalia as a pathological, parrotlike, and apparently senseless repetition (echoing) of a word or phrase ...just uttered by another person and classifies this condition among the “restrictive and repetitive behaviours” of Autism Spectrum Disorder (ASD). The authors reviewed the existing literature on echolalia and its role in the development of children with ASD. Current conceptualizations include echolalia among repetitive behaviors and stereotypies and thus interpret this symptom as lacking any communicative significance, with negative effects on learning and sensory processing. Echoic behaviors, however, have been described in neurotypical infants and children as having a substantial effect on the consequent development of language and communication. Relevant research has documented a functional role of echolalia in ASD children as well since it facilitates the acquisition of verbal competencies and affords a higher degree of semantic generalization. This developmental function could be restricted to specific contexts. Considering echolalia as stereotypy and treating it as a disturbing symptom could impair the development of ASD-specific learning and communication processes. In light of this evidence, the authors propose a different conceptualization of echolalia and suggest that this symptom be considered among atypical communication patterns in children with ASD, with implications for treatment and prognosis.
Abstract
Background
Recent research has documented the potential associations existing between the use of social media (SM) and the occurrence/development and treatment of Eating Disorders (ED). ...However, the literature directly addressing the use of SM TikTok among children and adolescents with ED is still scarce.
Methods
In January–February 2021, during the second Italian national lockdown due to the SARS-CoV-2 pandemic, an anonymous paper survey was conducted in an Italian third-level center for ED in childhood and adolescence. Demographics, frequency of use of TikTok, frequently viewed topics and hashtags, experienced body-shaming, as well as the use of TikTok (active search, use of proposed contents) and perceived influences of this SM on eating attitudes and self-esteem were assessed. Groups of patients with different perceived SM-induced effects were compared to determine the frequency of their interaction with 3 specific contents (diet, Pro-Anorexia Nervosa (pro-Ana) and pro-ED recovery).
Results
Seventy-eight patients (93.6% females, mean age 14.5 ± 2.1 years) were enrolled in the study. For 62.8%, TikTok represented the main SM, used for 1.4 ± 1.0 h/day, with diet (21.8%) as the most frequently used topic category. Pro-Ana and pro-ED recovery contents (“#foryou” and “#edrecovery” as the most frequent, respectively) were both actively searched by patients and proposed by the SM in a significant number of cases. For 59.0%, using TikTok reduced self-esteem, while 26.9% reported TikTok-related significant changes in their daily lives, and 3.8% reported experiences of body-shaming. Patients describing a negative effect of TikTok on their self-esteem more frequently searched and browsed “diet” (
p
= 0.007) and pro-ED recovery (
p
= 0.007) contents. Positive qualitative feedback on the SM was also reported.
Conclusions
This study documents the use of the SM TikTok among children and adolescents with ED. Individuals with a perceived negative effect of this SM on their self-esteem may show greater interaction with specific content. Further studies are needed to investigate the psychopathological factors influencing the relationship between ED and the use of SM.
Evidence about the use of pharmacologic agents in the treatment of Anorexia Nervosa (AN) is lacking, especially in childhood and adolescence. A systematic scoping review was conducted to outline ...current literature evidence about the use of antipsychotics in this population. A total of 499 studies were identified with the initial search, and 28 of these studies were selected regarding the use of olanzapine (n = 13), risperidone (n = 4), aripiprazole (n = 3), chlorpromazine (n = 3), pimozide (n = 1) clotiapine (n = 1) and multiple antipsychotics (n = 3) in these patients. Overall, major side effects were reported infrequently; improvements in psychopathology and weight measures have been suggested in the majority of the considered studies. Nonetheless, the lack of RCT or good-quality studies strongly limits the generalizability of results in clinical practice.
Although Anorexia Nervosa (AN) patients show dysfunctional behaviour in information processing, visual and verbal memory performance, and different cognitive fields, regardless of their BMI, the ...literature on the correlations between Eating Disorders (ED) and Neurodevelopmental Disorders (NDD) does not provide conclusive data. Rather than a consequence of the mental disorder, cognitive dysfunctions may be a risk factor for AN.
Our retrospective study investigates the prevalence of Specific Learning Disorder (SLD) among patients with ED. We considered 262 patients being treated at the Emilia Romagna Feeding and Eating Disorders Outpatient Service in Bologna, Italy. We compared the results with the Italian reference values, according to the most recent data provided by the Italian Ministry of Education.
We found that 25 patients out of 262 (9.54%) presented a comorbid diagnosis of SLD. This SLD prevalence is higher than the Italian reference values (4.9% in the school year 2018/19, p < 0.001). Comorbidity with SLD was significantly more frequent in males. A diagnosis of SLD was not associated with a higher frequency of any specific ED diagnosis or with psychiatric comorbidity in general. Positive family history for SLD was not significantly associated with either a positive family history for ED or a diagnosis of SLD.
This is the first Italian study to investigate the prevalence of SLD in ED patients during childhood and adolescence. Our data support previous research documenting that neuropsychological deficit could lead to the development of ED.
Atypical Anorexia Nervosa (AAN) is a Feeding and Eating Disorder characterized by fear of gaining weight and body image disturbance, in the absence of significantly low body weight. AAN may present ...specific clinical and psychopathological features. Nonetheless, the literature lacks data concerning the nutritional characteristics and body composition of children and adolescents with AAN and their variation over time.
Case series, including 17 children and adolescents with AAN. All the patients were assessed at the first evaluation (T0) with a standardized dietary assessment (24 h Dietary Recall, 24 hDR). Nutritional data were compared with European dietary reference values (DRVs). Body composition parameters (weight, fat mass, fat-free mass) and their changes over time at two (T1) and six (T2) months were collected as well, using a Bioelectrical impedance analysis (Wunder WBA300 with four poles and foot contact; impedance frequency 50 kHz 500 μA; impedance measurement range 200~1000 Ω/0.1 Ω).
The included individuals presented eating behaviors oriented towards significantly low daily energy intake (
< 0.001) compared with DRVs set by the European Food Safety Authority (EFSA) (with low carbohydrates and fats), and increased proteins (
< 0.001). A longer latency before observation (illness duration before observation) correlated with a negative change in weight. Body composition parameters were described, with no significant changes across the six-month outpatient assessment.
This is the first research to systematically assess the body composition and nutritional features of a group of individuals with AAN in the developmental age. Further research should assess the effect of targeted treatment interventions on body composition and nutritional features.
The present study investigates the impact of Autism Spectrum Disorder (ASD) traits on the treatment intensity and outcomes (psychopathology and weight) of 22 adolescent inpatients with Anorexia ...Nervosa (AN), who were selected on the basis of suspected ASD traits. ASD traits were measured at admission (T0) using the Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) and the Autism-Spectrum Quotient (AQ). Psychopathology was measured with Eating Disorder Inventory-3 (EDI-3) and Self-Administered Psychiatric Scales for Children and Adolescents (SAFA) at admission and discharge (T0, T1). Percentage BMI was assessed at admission, discharge, first follow-up (T2, 7–22 days) and second follow-up (T3, 22–45 days). Results were controlled for age and EDI-3 global psychological maladjustment. When compared with other patients with AN, AN individuals with ADOS-2 and AQ diagnostic scores for ASD showed overlapping types of treatments, as well as psychopathological and weight outcomes. ASD total scores were not correlated with treatment intensity or treatment outcomes. Preliminary results show that ASD traits do not impact treatment intensity and outcomes in adolescents with AN and suspected ASD traits.
