Brief Summary:
The role of gut microbiome was recently raised in the pathogenesis of neurodevelopmental disorders including autism spectrum disorder (ASD). In view of these evidences, together with poor conductance of researches on gut microbiota in ASD patients in Egypt, in addition to the absence of definite medical test or biological marker for diagnosis of ASD, the present study is designed to study clinical risk factor of autism and the predominant gut microbiome in autistic children in an attempt to identify gut bacteria which are likely related to ASD and to correlate these bacteria and clinical variables with the severity of autism. Interestingly, the totality of the studies focusing on the fecal metabolome features in ASD has investigated the differences between subjects with and without this disorder, while ignoring potential correlations between microbiome, metabolome and ASD severity
Detailed Description:
Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders characterized by impairment in communication and social interaction, and repetitive behaviors. 1%-1.5% of children in developed nations has ASD, This rate is said to range between 0.15% and 0.8% in low- and middle-income countries. Over the past decades, the prevalence of ASD has increased worldwide. Scientists have been trying to explore the molecular mechanisms behind the pathology of ASD. Several evidence suggests that genetic factors such as chromosomal abnormalities and environmental factors like diet and stress are involved in the pathogenesis and advancement of ASD. Accumulating research has demonstrated the gut-brain axis or multiple biochemical signaling pathways that take place between the gastrointestinal tract (GI tract) and the central nervous system (CNS), and its possible association with ASD. Mounting evidence explains that gut microbial dysbiosis is implicated in the pathogenesis of multiple diseases, including inflammatory bowel disease (IBS), coeliac disease (CD), and ASD. A Recent Egyptian study showed that an evidence of changes in the gut microbiome of ASD children compared to the unrelated controls. However, the microbiome profile of siblings was more like that of autistic children than that of unrelated controls. These observations may highlight the importance of the interplay between environmental and host genetic factors in shaping the gut microbiome. The study also emphasized the importance of identification of microbiome and specific microorganisms' changes that can be targeted for diagnosis as well as for treatment of ASD. This study aims to investigate clinical risk factors of autism and to elucidate the changes in gut microbiome in Egyptian autistic children and their possible correlation with clinical outcomes and the severity of the disease.
