The Effects of Probiotics and Prebiotics on Gastrointestinal and Behavioural Symptoms in Autism Spectrum Disorder

Background: Autism Spectrum Disorders (ASDs) are a group of prevalent neuropsychiatric disorders. They present a complex and unknown etiology, which in most cases includes significant peripheral alterations outside the brain such as in the composition of gut microbiota. Because the gut microbiota is involved in modulating the gut-brain axis, several studies have suggested that the microbiome in the gut can modify metabolites which are able to cross the blood-brain barrier and modulate brain function. Methods: We reviewed the current evidence regarding microbiota alterations in patients with ASD and the effects of the administration of probiotics and prebiotics in these patients, both in te…

Febrile seizure and related syndromes

Abstract Febrile seizures (FS) are the result of particular sensitivity to fever in the developing brain, have a major genetic predisposition, and nearly always have a benign outcome. Febrile seizures are the most common for of seizures in childhood. They have been observed in 2–6% of children before the age of 5 years, but in some populations this figure increase to 15%. Febrile seizures could be the first manifestations of epilepsy. About 13% of epileptic patients have a history of febrile seizures, and 30% have had recurrent febrile seizures Their phenotypic characteristics allow, in the majority of cases, a classification of the seizure, an elaboration of a prognosis and to assume a spe…

First Case Report of Primary Carnitine Deficiency Manifested as Intellectual Disability and Autism Spectrum Disorder

Systemic primary carnitine deficiency (PCD) is a genetic disorder caused by decreased or absent organic cation transporter type 2 (OCTN2) carnitine transporter activity, resulting in low serum carnitine levels and decreased carnitine accumulation inside cells. In early life, PCD is usually diagnosed as a metabolic decompensation, presenting as hypoketotic hypoglycemia, Reye syndrome, or sudden infant death; in childhood, PCD presents with skeletal or cardiac myopathy. However, the clinical presentation of PCD characterized by autism spectrum disorder (ASD) with intellectual disability (ID) has seldom been reported in the literature. In this report, we describe the clinical features of a sev…

Skeletal alterations, developmental delay and new mutations in juvenile-onset Pompe disease.

Abstract Pompe disease is an autosomal recessive disorder caused by a deficiency of acid α-glucosidase. In addition to the severe infantile form with cardiac involvement, late-onset variants can affect older children, adolescents (aged >1 year old) or adults. Patients with juvenile (a subgroup of late-onset type) Pompe disease typically do not have cardiac alterations e.g. hypertrophic cardiomyopathy, and the diagnosis is often difficult because it can clinically resemble myriad other neuromuscular disorders. A high level of clinical suspicion is necessary for a timely and accurate diagnosis. We describe 3 interesting cases of patients with juvenile-onset Pompe disease who presented some un…

Autism and Intellectual Disability Associated with Mitochondrial Disease and Hyperlactacidemia

Autism spectrum disorder (ASD) with intellectual disability (ID) is a life-long debilitating condition, which is characterized by cognitive function impairment and other neurological signs. Children with ASD-ID typically attain motor skills with a significant delay. A sub-group of ASD-IDs has been linked to hyperlactacidemia and alterations in mitochondrial respiratory chain activity. The objective of this report is to describe the clinical features of patients with these comorbidities in order to shed light on difficult diagnostic and therapeutic approaches in such patients. We reported the different clinical features of children with ID associated with hyperlactacidemia and deficiencies i…
