Abstract

Autism spectrum disorder (ASD) is a series of complex neurobiological disorders. Adolescents and young adults with ASD are more likely to develop type 2 diabetes mellitus in their later life than those who are not. However, whether ASD patients exhibited a pre-diabetic phenotype in their childhood is still unknown. To answer this question, here we presented this study which focus on whether oral glucose tolerance, insulin and C-peptide release were changed in children with ASD. We recruited 17 patients and 17 age and sex-matched typically developing children in our study. In our study, the fasting blood glucose was significantly decreased in children with ASD. Moreover, two children in the ASD group had impaired glucose tolerance according to 2-hour postprandial blood glucose level. The C-peptide level at 30 minutes after glucose administration in the ASD group was significantly lower than that in the control group. Moreover, four children in the ASD group showed a phenomenon of delayed insulin secretion. All these results suggested that a subgroup of children with ASD might exhibit a pre-diabetic phenotype during early childhood. Finally, this study might bring about new therapeutic interventions for children with ASD.

Lay Summary: The etiology of ASD seems to involve an intricate interplay of genetic, environmental and metabolic disorders. Adolescents and young adults with ASD are more likely to develop type 2 diabetes mellitus in their later life. It is important to find out whether ASD patients exhibited a pre-diabetic phenotype in their childhood. This study provided evidence for dysfunction risk of glucose metabolism in ASD and revealed a pre-diabetes phenotype in children with ASD.

Role of Topical Insulin in Venous Ulcer Management

Wound healing is a dynamic process whereby cellular structures and the tissue layers are reconstructed. Adult wound healing can be categorized into three stages: inflammatory phase, proliferative phase, and remodelling phase. Blood cells like macrophages, neutrophils, extracellular matrix and mediators, various proteins, and various genes play an important role in these phases.

The Link of Nutrient Fluxes to Hepatic Insulin Resistance at Gene Expression

Insulin resistance has been studied extensively at systemic, organ, tissue and cellular and molecular levels. Overnutrition plays an essential role in the development of chronic metabolic diseases such as obesity and type 2 diabetes. For subjects without genetic defects, the development of insulin resistance and type 2 diabetes is a graduate process. How the transition from an insulinsensitive state to an insulin-resistant state occurs, and what the roles of nutrients are in the process have not been fully understood. Here, we try to summarize the current understanding of insulin-regulate gene expression in the liver, and describe a phenomenon of hepatic insulin resistance at gene expression (HIRAGE), which may be linked to overnutrition.

 

Improving Obesity and Insulin Resistance by Targeting Skeletal Muscle MKP-1

Obesity has reached a global epidemic and it predisposes to the development of insulin resistance, type 2 diabetes and related metabolic diseases. Current interventions against obesity and/or type 2 diabetes such as calorie restriction, exercise, genetic manipulations or established pharmacological treatments have not been successful for many patients with obesity and/or type 2 diabetes.

The Clinical Utility of Outpatient Continuous Glucose Monitoring in Establishing Insulinoma Diagnosis in a Patient with Impaired Nocturnal Hypoglycemia Awareness

Insulinomas are insulin secreting tumors arising from spontaneous mutations of the ductal, acinar, or islet cells of the pancreas. They are rare, having an incidence of only four cases per million people per year. Patients typically present with fasting hypoglycemia, experiencing neurologic symptoms like confusion, changes in vision, or abnormal behavior and autonomic symptoms like palpitations, diaphoresis, or tremulousness.

Altered Peak C-peptide and Fasting Blood Glucose in Children with Autism Spectrum Disorder

ASD refers to a group of complex neurodevelopmental disorders, characterized by deficits in social communication, interaction and demonstrating restricted, repetitive, and stereotyped patterns of behavior. Centers for Disease Control and Prevention forecasted that the prevalence of ASD would be 1 in 45 in USA.
