OBJECTIVE Sleep difficulties are common reasons why parents seek medical intervention in children with autism spectrum disorders (ASDs). We determined whether a pamphlet alone could be used by parents to help their child’s insomnia. METHODS Thirty-six children with ASD, ages 2 to 10 years, were enrolled. All had prolonged sleep latency confirmed by actigraphy showing a mean sleep latency of 30 minutes or more. Parents were randomly assigned to receive the sleep education pamphlet or no intervention. Children wore an actigraphy device to record baseline sleep parameters, with the primary outcome variable being change in sleep latency. Actigraphy data were collected a second time 2 weeks after the parent received the randomization assignment and analyzed by using Student’s t test. Parents were also asked a series of questions to gather information about the pamphlet and its usefulness. RESULTS Although participants randomized to the 2 arms did not differ statistically in age, gender, socioeconomic status, total Children’s Sleep Habits Questionnaire score, or actigraphy parameters, some differences may be large enough to affect results. Mean change in sleep-onset latency did not differ between the randomized groups (pamphlet versus no pamphlet). Parents commented that the pamphlet contained good information, but indicated that it would have been more useful to be given specific examples of how to take the information and put it into practice. CONCLUSIONS A sleep education pamphlet did not appear to improve sleep latency in children with ASDs.

We performed a retrospective chart review of 50 youths with Autism Spectrum Disorder (ASD), prescribed amitriptyline (AMI) for hyperactivity and impulsivity. Data was systematically extracted from 50 outpatient clinic charts, including AMI treatment duration, dose, trough levels and adverse events. Mean age was 9.4 years (4.6-17.9); 40 were males and 10 females. 30 % had failed atomoxetine and 40 % had failed >/=3 ADHD medications. Mean dose was 1.3 +/- 0.6 mg/kg/day, mean trough level 114.1 +/- 50.5 ng/ml, mean duration 3.4 years.

Diminished social attention is often considered to be a central deficit in autism spectrum disorders (ASDs). We further investigate this hypothesis by measuring the distracting power of social and non-social stimuli in the context of a Stroop task among children with ASD and typically developing controls (TDCs). Our results show that Stroop interference increases with social versus non-social distracters in TDCs, whereas the opposite pattern occurs in ASD. Within social stimuli, however, the superiority of direct gaze previously reported in the literature did not differ between the groups. Our data thus suggest that ASD children assign less weight to social than non-social stimuli, but that within social signals, salient stimuli remain prioritized.

OBJECTIVES The goal of this study was to examine rates of psychotropic medication use and identify associated child and family characteristics among children and adolescents with autism spectrum disorder (ASD) enrolled in an autism registry maintained by the Autism Treatment Network (ATN). METHODS The sample, derived from the ATN registry, consists of 2853 children aged 2 to 17 years with diagnoses of ASD supported by Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, and the Autism Diagnostic Observation Schedule with available data on medication use. As part of initial enrollment in the registry, parents completed questionnaires on current psychotropic medication use, psychiatric and medical conditions, and demographics. RESULTS Of the 2853 children, 763 (27%) were taking >/=1 psychotropic medication; 15% were prescribed 1 medication, 7.4% received 2 medications, and 4.5% received >/=3. Among children aged 3 to 5 years, 11% were taking >/=1 psychotropic medication; among 6- to 11-year-old children, 46%; and 66% of adolescents aged 12 to 17 years were taking at >/=1 psychotropic medication. A parent report of comorbid diagnosis of attention-deficit/hyperactivity disorder, bipolar disorder, obsessive-compulsive disorder, depression, or anxiety was associated with a high rate of use, with 80% receiving >/=1 psychotropic medication. Only 15% of children with no comorbid psychiatric disorder were taking psychotropic medication. Psychotropic medication use was also related to sleep and gastrointestinal problems. CONCLUSIONS The prescription of psychotropic medications in this registry sample is highly related to comorbid psychiatric disorder. Other factors associated with use include medical comorbidities, race, ethnicity, and older age.

OBJECTIVE To determine whether the proportion of time spent in an inclusive educational setting, a process indicator of the quality of schooling for children with autism, improves key outcomes. METHODS Patients were 484 children and youth educated in special education with a primary diagnosis of autism in the National Longitudinal Transition Study-2. These individuals were ages 20 to 23 in 2007. We used propensity-score inverse probability of treatment weights to eliminate the effect of multiple confounders. A causal interpretation of the effect of inclusivity on key educational and functional outcomes still depends on a critical assumption, that inclusivity is not confounded by remaining, omitted confounders. RESULTS Compared with children with autism who were not educated in an inclusive setting (n = 215), children with autism who spent 75% to 100% of their time in a general education classroom (n = 82) were no more likely to attend college (P = .40), not drop out of high school (P = .24), or have an improved functional cognitive score (P = .99) after controlling for key confounders. CONCLUSIONS We find no systematic indication that the level of inclusivity improves key future outcomes. Research on educational and functional outcomes for children with autism can benefit from data on large samples of children educated in real-world settings, such as the National Longitudinal Transition Study-2, but more nuanced indicators should be developed to measure the quality of special education for children with autism.

OBJECTIVES To develop a practical, readily applied algorithm for primary health care providers to identify, evaluate, and manage constipation in children with autism spectrum disorders (ASDs). METHODS The Gastroenterology Committee of the Autism Speaks Autism Treatment Network (ATN), a multisite consortium of centers dedicated to improving standards of medical care for children with ASDs, guided the development of the constipation algorithm through expert opinion and literature review. The algorithm was finalized based on results of field testing by nongastrointestinal, ATN autism medical specialists at 4 ATN sites. A systematic review and grading of the literature pertaining to constipation and children with ASDs was also performed. RESULTS Consensus among the ATN Gastroenterology Committee identified that in children with ASDs, (1) subtle or atypical symptoms might indicate the presence of constipation; (2) screening, identification, and treatment through a deliberate approach for underlying causes of constipation is appropriate; (3) diagnostic-therapeutic intervention can be provided when constipation is documented; and (4) careful follow-up after any intervention be performed to evaluate effectiveness and tolerance of the therapy. Literature review revealed limited evidence for the clinical evaluation or treatment strategies of children with ASD and constipation. CONCLUSIONS Constipation and its underlying etiology have the potential to be effectively identified and managed using a systematic approach. Lack of evidence on this topic in the literature emphasizes the need for research.

ABSTRACT: BACKGROUND: Having a ‘theory of mind’, or having the ability to attribute mental states to oneself or others, is considered one of the most central domains of impairment among children with an autism spectrum disorder (ASD). Many interventions focus on improving theory of mind skills in children with ASD. Nonetheless, the empirical evidence for the effect of these interventions is limited. The main goal of this study is to examine the effectiveness of a short theory of mind intervention for children with ASD. A second objective is to determine which subgroups within the autism spectrum profit most from the intervention. METHODS: This study is a randomized controlled trial. One hundred children with ASD, aged 7 to 12 years will be randomly assigned to an intervention or a waiting list control group. Outcome measures include the completion of theory of mind and emotion understanding tasks, and parent and teacher questionnaires on children’s social skills. Follow-up data for the intervention group will be collected 6 months after the interventions. DISCUSSION: This study evaluates the efficacy of a theory of mind intervention for children with ASD. Hypotheses, strengths, and limitations of the study are discussed.Trial registrationNetherlands Trial Register NTR2327.

OBJECTIVE The impact of abnormal feeding behaviors reported for children with autism spectrum disorders (ASDs) on their nutritional status is unknown. We compared nutrient intake from food consumed by children with and without ASD and examined nutrient deficiency and excess. METHODS Prospective 3-day food records and BMI for children (2-11 years) with ASD participating in the Autism Treatment Network (Arkansas, Cincinnati, Colorado, Pittsburgh, and Rochester) were compared with both the National Health and Nutrition Examination Survey data and a matched subset based on age, gender, family income, and race/ethnicity (N = 252 analyzed food records). RESULTS Children with ASD and matched controls consumed similar amounts of nutrients from food. Only children with ASD aged 4 to 8 years consumed significantly less energy, vitamins A and C, and the mineral Zn; and those 9 to 11 years consumed less phosphorous. A greater percentage of children with ASD met recommendations for vitamins K and E. Few children in either group met the recommended intakes for fiber, choline, calcium, vitamin D, vitamin K, and potassium. Specific age groups consumed excessive amounts of sodium, folate, manganese, zinc, vitamin A (retinol), selenium, and copper. No differences were observed in nutritional sufficiency of children given restricted diets. Children aged 2 to 5 years with ASD had more overweight and obesity, and children 5 to 11 years had more underweight. CONCLUSIONS Children with ASD, like other children in America, consume less than the recommended amounts of certain nutrients from food. Primary care for all children should include nutritional surveillance and attention to BMI.

OBJECTIVES To examine long-term outcomes of toddlers with autism spectrum disorder (ASD) who received a 6-month early intervention at age 2. METHODS Forty-eight toddlers diagnosed with an ASD received a 6-month evidence-based intervention. Cognitive (IQ) and communication ability, as well as severity of autism symptoms, were assessed by using standardized measures at preintervention (Time 1 [T1]; mean [M] age = 27 months), postintervention (T2; M age = 35 months), short-term follow-up (T3; M age = 41 months), and long-term follow-up (T4; M age = 72 months). RESULTS From pre- to postintervention, significant gains in IQ and Vineland Communication domain standard scores as well as a reduction in ASD severity were achieved (all P < .01). Between T2 and T3, the 6-month period immediately after completion of the intervention, IQ and Communication scores stabilized and ASD severity increased significantly (P < .05). During the long-term follow-up period (T3-T4), IQ and Communication scores significantly increased again, but ASD severity increased significantly as well (all P < .05). For overall trajectory (T1-T4), robust gains were observed for both IQ and communication; ASD severity did not change. CONCLUSIONS Findings highlight the potential for positive long-term outcomes in toddlers with ASD. Additional research is needed to understand the relation between early exposure to uninterrupted intervention and developmental gains, and whether initial reduction in ASD symptom severity can be sustained through targeted intervention.

OBJECTIVES Recent census data show that nearly one-quarter of US children have at least 1 immigrant parent; moreover, there has been a dramatic increase in children diagnosed with autism spectrum disorders (ASDs) and select developmental disabilities (DDs). However, little is known about access to medical home and adequacy of insurance coverage for children with ASDs and select DDs from immigrant families. METHODS By using the 2007 National Survey of Children’s Health, we compared children with ASDs and select DDs from immigrant (n = 413, foreign born or reside with at least 1 immigrant parent) and nonimmigrant (n = 5411) families on various measures of medical home and insurance coverage. We used weighted logistic regression to examine the association between immigrant family and selected outcome measures while controlling for confounding factors. RESULTS Compared with nonimmigrant families, children with ASD and select DD from immigrant families were more than twice as likely to lack usual source of care and report physicians not spending enough time with family. Furthermore, multivariable analyses indicate that insurance coverage is an important factor in mitigating health care barriers for immigrant families. CONCLUSIONS The study demonstrates important areas of deficits in the health care experiences of children with ASD and select DD from immigrant households. Public policy implications include increasing access to existing insurance programs, augmenting public awareness resources for ASD and select DD, and offering assistance to immigrant families that are struggling with the medical needs of their children.

BACKGROUND AND OBJECTIVE Hyperactivity, impulsivity, and inattention (referred to as « ADHD [attention-deficit/hyperactivity disorder] symptoms ») occur in 41% to 78% of children with autism spectrum disorders (ASDs). These symptoms often affect quality of life, interfering with learning or interventions that target primary ASD symptoms. This practice pathway describes the guidelines for evaluation and treatment of children and adolescents with ASD and comorbid ADHD symptoms. METHODS Current research in this area is limited, and, therefore, these recommendations are based on a systematic literature review and expert consensus in the Autism Speaks Autism Treatment Network Psychopharmacology Committee. RESULTS The recommended practice pathway includes the Symptom Evaluation Pathway for systematic assessment of ADHD symptoms across settings; examination for comorbid sleep, medical, or psychiatric comorbidities that may contribute to symptoms; and evaluation of behavioral interventions that may ameliorate these symptoms. For children for whom medication is being considered to target the ADHD symptoms, the medication choice pathway provides guidance on the selection of the appropriate agent based on a review of available research, assessment of specific advantages and disadvantages of each agent, and dosing considerations. CONCLUSIONS These recommendations provide a framework for primary care providers treating children who have ASD and ADHD symptoms. Our systematic review of the current evidence indicates the need for more randomized controlled trials of the medications for ADHD symptoms in ASD. There will also be a need for studies of the effectiveness of these practice pathways in the future.

OBJECTIVE This report describes the development of a practice pathway for the identification, evaluation, and management of insomnia in children and adolescents who have autism spectrum disorders (ASDs). METHODS The Sleep Committee of the Autism Treatment Network (ATN) developed a practice pathway, based on expert consensus, to capture best practices for an overarching approach to insomnia by a general pediatrician, primary care provider, or autism medical specialist, including identification, evaluation, and management. A field test at 4 ATN sites was used to evaluate the pathway. In addition, a systematic literature review and grading of evidence provided data regarding treatments of insomnia in children who have neurodevelopmental disabilities. RESULTS The literature review revealed that current treatments for insomnia in children who have ASD show promise for behavioral/educational interventions and melatonin trials. However, there is a paucity of evidence, supporting the need for additional research. Consensus among the ATN sleep medicine committee experts included: (1) all children who have ASD should be screened for insomnia; (2) screening should be done for potential contributing factors, including other medical problems; (3) the need for therapeutic intervention should be determined; (4) therapeutic interventions should begin with parent education in the use of behavioral approaches as a first-line approach; (5) pharmacologic therapy may be indicated in certain situations; and (6) there should be follow-up after any intervention to evaluate effectiveness and tolerance of the therapy. Field testing of the practice pathway by autism medical specialists allowed for refinement of the practice pathway. CONCLUSIONS The insomnia practice pathway may help health care providers to identify and manage insomnia symptoms in children and adolescents who have ASD. It may also provide a framework to evaluate the impact of contributing factors on insomnia and to test the effectiveness of nonpharmacologic and pharmacologic treatment strategies for the nighttime symptoms and daytime functioning and quality of life in ASD.

The purpose of this study was to gain an in-depth understanding of autism intervention in China, including history, progress, and current challenges. This qualitative research study included interviews with experienced professionals and observation at autism intervention organizations. Analysis of this empirical data led to three themes regarding this field. First, the development of the field can be described using the Chinese expression, mozhe shitou guohe (feeling stones to cross the river). Owing to limited exposure to outside information, methods are often created independent of research-based best practices. Second, autism intervention in China has had a strong, and until recently, almost exclusive, focus on young children. Finally, there are continued challenges to providing effective services that relate to the desires of parents and professionals to provide ‘more’; a focus on quantity may be preventing a focus on quality. The article concludes with an analysis of the findings and practical implications that may be used by practitioners or scholars planning to do work in China.

Autism spectrum disorders (ASD) are a group of biological disorders with associated metabolic derangement. This study aimed to identify a pattern of metabolic perturbance in ASD using metabolomics in urinary specimens from 48 children with ASD and 53 age matched controls. Using a combination of liquid- and gas-chromatography-based mass spectrometry, we detected the levels of 82 metabolites (53 of which were increased) that were significantly altered between the ASD and the control groups using osmolality normalized data. Pattern analysis showed that the levels of several amino acids such as glycine, serine, threonine, alanine, histidine, glutamyl amino acids and the organic acid, taurine were significantly (p Lien vers le texte intégral (Open Access ou abonnement)

BACKGROUND AND OBJECTIVE Children and adolescents with autism spectrum disorder (ASD) often use complementary and alternative medicine (CAM), usually along with other medical care. This study aimed to determine associations of ASD diagnostic category, co-existing conditions, and use of medications with use of CAM. METHODS We used the Autism Speaks Autism Treatment Network patient registry, which collects information on CAM use, medical conditions, and psychotropic medication at enrollment. CAM was categorized as special diets versus « other » CAM; ASD was defined as autism, pervasive developmental disorder (PDD), or Asperger’s. Gastrointestinal symptoms, seizure disorders, sleep problems, and medication use were determined from parent report. Child Behavior Checklist (CBCL) scores were used to measure behavioral symptoms. Logistic regression was used to determine associations of diagnostic category, other medical conditions, and medication use with CAM treatments, controlling for demographic characteristics. RESULTS Of 3413 subjects in the registry as of April 2011, 3173 had complete data on CAM use: 896 (28%) reported any use; 548 (17%), special diets; and 643 (20%), other CAM. Higher rates of CAM use were associated with gastrointestinal symptoms (odds ratio [OR] = 1.88), seizures (OR = 1.58), and CBCL total score >70 (OR = 1.29). Children with PDD (OR = 0.62), Asperger’s (OR = 0.66), or using medications (0.69) had lower rates. CONCLUSIONS Children with ASD use more CAM when they have co-existing gastrointestinal symptoms, seizure disorders, and behavior problems. This study suggests the importance of asking about CAM use in children with ASD, especially those with complex symptoms.

BACKGROUND AND OBJECTIVES Children with autism spectrum disorders (ASDs) often have food selectivity and restricted diets, putting them at risk for nutritional deficiencies. Previous studies have demonstrated a high prevalence of iron deficiency (ID) in children with ASDs living in Wales, Canada, and Turkey. The objectives of this study were to determine the prevalence of ID and the adequacy of iron intake in children with ASD in the United States. METHODS Participants (age 2-11 years recruited from the Autism Treatment Network Diet and Nutrition Study) completed a 3-day diet record (n = 368) and had laboratory measures of serum ferritin (SF), complete blood count, iron, total iron binding capacity, and transferrin saturation (TS) (n = 222). RESULTS Of the 222 participants with laboratory data, 18 (8%) had SF <12 microg/L and 2 (1%) had ID defined by both low SF and TS (3 children with low SF had missing TS data). One subject had iron deficiency anemia. Fewer than 2% of subjects had iron intake below the estimated average requirement. CONCLUSIONS Although the determination of iron status is complex, these data do not support previous reports that children with ASD are at greater risk for ID than the general population; however, 8% percent of the sample did demonstrate low SF despite <2% of the sample demonstrating iron intake below the estimated average requirement. The prevalence of low SF may be an underestimate, because SF is an acute phase reactant and the study included no measure of inflammation. Lien vers le texte intégral (Open Access ou abonnement)

BACKGROUND The purpose of the current study was to evaluate the relationships among sleep problems and daytime behaviors in a large, well-defined cohort of children with autism spectrum disorder (ASD). METHODS Out of a registry population of 3452 children with ASDs, a subset of 1193 children aged 4 to 10 years of age from 14 centers across the country was used to evaluate the relationship between varying levels of sleep problems and daytime behavior. Measures included Children’s Sleep Habits Questionnaire, Vineland Adaptive Behavior Scales, Survey Interview Form, Second Edition, and Child Behavior Checklist. Multiple analysis of covariance was used to assess the association between sleep and behavior. RESULTS Results suggest that sleep problems, as identified by parent report by use of the Children’s Sleep Habits Questionnaire, have a negative relationship with daytime behavior. More specifically, children with ASDs and sleep problems had more internalizing and externalizing behavior problems, as measured by the Child Behavior Checklist, and poorer adaptive skill development, as measured by the Vineland Adaptive Behavior Scales, than children with ASDs and no sleep problems. Children with moderate to severe sleep problems had greater behavior difficulties, but not necessarily poorer adaptive functioning, than children with mild to moderate sleep problems. Both preschool- and school-aged children demonstrated a negative relationship between behavior and sleep, whereas the relationship between sleep and adaptive functioning was much more variable. CONCLUSIONS These results suggest that, although sleep has a negative relationship with internalizing and externalizing behavior, it may have a different relationship with the acquisition of adaptive skills.

OBJECTIVE The purpose of the current study was to evaluate the frequency of co-occurring attention-deficit/hyperactivity disorder (ADHD) symptoms in a well-defined cohort of children with autism spectrum disorders (ASDs) and to examine the relationship between ADHD symptoms and both adaptive functioning and health-related quality of life as reported by parents or other primary caregivers. METHODS T scores on 2 ADHD-related scales from the Child Behavior Checklist were used to indicate the presence of ADHD symptoms. Participants were divided into groups based on whether their parents/caregivers rated them as having clinically significant T scores on the Attention Problem and Attention Deficit Hyperactivity Problem subscales. Standard scores from the Vineland Adaptive Behavior Scales, Second Edition and raw scores from the Pediatric Quality of Life Inventory were then compared between groups with the use of multivariate analyses. RESULTS Approximately 40% of participants had 1 elevated T score, and 19% had both ADHD-related T scores elevated on the Child Behavior Checklist. The ASD + ADHD group had lower scores on the Vineland Adaptive Behavior Scales, Second Edition and the Pediatric Quality of Life Inventory in comparison with the ASD alone group. CONCLUSIONS Results suggest greater impairment in adaptive functioning and a poorer health-related quality of life for children with ASDs and clinically significant ADHD symptoms in comparison with children with ASDs and fewer ADHD symptoms. Physicians are encouraged to evaluate for the presence of ADHD symptoms in their patients with ASDs and, if present, include symptom treatment in the overall care plan.
