Could autism spectrum disorders be a risk factor for COVID-19?

ABSTRACT: The coronavirus SARS-CoV-2 pandemia is infecting millions of people and some studies relate conditions that might increase the risk of developing a fatal course for the disease, such as diabetes, cardiovascular diseases and obesity. In COVID-19 physiopathology, one of the main inflammation mechanisms is the "cytokine storm", causing a pro-inflammatory state, related to cardiac and pulmonary damage. There is also a less effective role of lymphocyte B and T in the humoral immunity due to the reduction of their proliferative response. The physiopathology of ASD (Autism Spectrum Disorder) involves several modifications at the genetic and at the immune level, such as the increase of inflammatory cytokines and abnormal immune response in several levels. We hypothesize that ASD could be a risk-factor as the other conditions are.

Project description:Autistic spectrum disorders are childhood neurodevelopmental disorders characterized by social and communicative impairment and repetitive and stereotypical behavior. Macrophage migration inhibitory factor (MIF) is an upstream regulator of innate immunity that promotes monocyte/macrophage-activation responses by increasing the expression of Toll-like receptors and inhibiting activation-induced apoptosis. On the basis of results of previous genetic linkage studies and reported altered innate immune response in autism spectrum disorder, we hypothesized that MIF could represent a candidate gene for autism spectrum disorder or its diagnostic components.Genetic association between autism spectrum disorder and MIF was investigated in 2 independent sets of families of probands with autism spectrum disorder, from the United States (527 participants from 152 families) and Holland (532 participants from 183 families). Probands and their siblings, when available, were evaluated with clinical instruments used for autism spectrum disorder diagnoses. Genotyping was performed for 2 polymorphisms in the promoter region of the MIF gene in both samples sequentially. In addition, MIF plasma analyses were conducted in a subset of Dutch patients from whom plasma was available.There were genetic associations between known functional polymorphisms in the promoter for MIF and autism spectrum disorder-related behaviors. Also, probands with autism spectrum disorder exhibited higher circulating MIF levels than did their unaffected siblings, and plasma MIF concentrations correlated with the severity of multiple autism spectrum disorder symptoms.These results identify MIF as a possible susceptibility gene for autism spectrum disorder. Additional research is warranted on the precise relationship between MIF and the behavioral components of autism spectrum disorder, the mechanism by which MIF contributes to autism spectrum disorder pathogenesis, and the clinical use of MIF genotyping.
