Effects of Metformin on Androgens and Other Steroid Hormones in Affected Subjects With Autism

Sponsor: Insel Gruppe AG, University Hospital Bern

Summary

Autism is diagnosed with increasing frequency in recent years despite remaining uncertainty concerning the cause. The disorder is characterized by deficits in social behavior, a lack of communication skills, and repetitive and stereotypical interests. As part of the research, It attempted to pursue the hypothesis that the disorder is signed by an endocrine involvement. Therefore, the original description of Hans Asperger was analyzed first. This was followed by comprehensive steroid hormone analyses in girls and boys with autism. Based on the assumption that steroid hormones are involved, dysregulation of the adrenal gland for all metabolite classes - mineralocorticoid, glucocorticoid, androgen - were identified. The subsequently followed animal experiments yielded to the conclusion that a dysregulation of the hypothalamic-pituitary system might be responsible for the autistic behavior. This is also probably associated with overactivity of 17/20 lyase, an orchestrating enzyme of oxidative stress, which is driven by p38. It is suspected that the increased oxidative stress is of mitochondrial origin and thus other metabolic cascades are involved. Due to the developed understanding of the suspected dysregulation, new therapeutic options for treatment are opening up, with metformin in particular - known for its antiandrogenic effect used in poly cystic ovarian syndrome - appearing to have the best effect on social withdrawal in the developed mouse model. Initial urine analyses allow the assumption that metformin directly influences steroidogenesis, and thus opens up the possibility of a clinical trial for affected subjects with autism.
