quetiapine-fumarate and Autism-Spectrum-Disorder

Radiopaque densities can be observed on imaging after the ingestion of either foreign bodies or some medications. Our case report discusses an 11-year-old boy with autism spectrum disorder and attention deficient disorder who presented to the emergency department because of concerns for constipation and dehydration. Incidentally, an abdominal x-ray showed numerous radiopaque densities throughout his intestines in addition to his constipation. He was admitted, and his home regimen was reviewed to attempt to identify a potential source for these radiopaque densities. This case presented an interesting teaching opportunity in the identification of the radiopaque densities and review of pharmacokinetics.

Nowadays, adults with autism spectrum disorder (ASD) experience several comorbidities whose treatment implies a wide range of psychotropic prescriptions. This study aimed to evaluate medication-related safety, drug-drug interactions, and psychotropics prescription trends. We conducted an observational and multicentric pharmacovigilance study in subjects with ASD and Intellectual disability (ID, n = 83). Clinical information (diagnoses, ongoing medications, comorbidities [multimorbidity ≥ 4 chronic health conditions]) and psychotropic prescriptions (polypharmacy ≥ 4 chronic drugs, daily drug doses, co-prescription) were registered. Ethical approval for this study was obtained. Participants (30±10 years old, 86% men, BMI 27±6 kg/m2) displayed 37% multimorbidity (mean of 3, IQR 2-4), and 57% polypharmacy (13% out of dose recommended range). Most drugs prescribed were psychotropic risperidone which is related to nervous system comorbidities (18% epilepsy, 16% insomnia, and 14% psychotic agitations). Risperidone and quetiapine were co-prescribed in 60% of the cases without any monitoring adverse event routine. The rates of multimorbidity and polypharmacy, among our young adults with ASD and ID, are concerning. Data suggest the need to develop a pharmacovigilance monitoring system to evaluate prescription accuracy, long-term safety of ongoing medications, and the fixed doses in this autistic population with associated ID.

Successful use of acetylcysteine to control irritability and aggressive behaviors in a hospitalized adolescent patient with autism spectrum disorder (ASD) is described.. A 17-year-old Hispanic male with ASD and intellectual disability was hospitalized for inpatient psychiatric treatment due to impulsive and violent behavior. Despite receiving various medications in the initial weeks of hospitalization, including intramuscular lorazepam and diphenhydramine injections (four days a week on average), the patient continued to exhibit aggressive and unpredictable behaviors. Treatment with 20% acetylcysteine oral solution was initiated at a dosage of 600 mg twice daily as an adjunct to quetiapine therapy. Over the next six weeks, reductions in the patient's aggressive behavior, tantrums, and irritability were noted. The use of as-needed medications to control aggression was decreased, and the dosage of quetiapine was lowered from 700 to 400 mg daily over the course of the hospitalization. Acetylcysteine was well tolerated, with no observed or reported adverse effects. Unlike clonidine or guanfacine (other medications used for ASD-related behavioral symptoms), acetylcysteine is not sedating; moreover, it lacks the metabolic, extrapyramidal, and endocrine adverse effects of atypical antipsychotics. Published data from small controlled trials and case reports suggest that acetylcysteine use is associated with improvements in irritability and aggression in prepubertal children with ASD; these therapeutic benefits may be associated with acetylcysteine's glutamatergic, dopaminergic, antioxidant, and anti-inflammatory properties.. Treatment with acetylcysteine improved ASD symptoms, including irritability and aggression, in a teenage patient.
