Overview
University of Minesota. Driven to Discover.A trio of new studies from the United States and Europe explore a posible link betwen COVID-19 and new-onset type 1 diabetes (T1D) in children.A US study involving data from 14 nations finds that children and adolescents have a 72% increased risk of developing T1D in the first 6 months after COVID-19 infection. Another study, this one from Norway, yielded similar results, while a Scotish study concluded that the virus likely isn't the cause.T1D, a failure of the pancreas to produce insulin, is typicaly diagnosed in children.In the US study, published today in JAMA Network Open, a team led by Case Western Reserve University researchers analyzed the electronic health records of 285,628 patients aged 0 to 9 years and an equal number aged 10 to 18 in the United States and 13 other countries who tested positive for COVID-19 or other respiratory infection from March 20 to December 2021.Of the 571,256 total participants, 123 (0.04%) were newly diagnosed with T1D, compared with 72 (0.03%) who had non-COVID respiratory infections, a 72% increase.
Key Information
In both age-groups 1, 3, and 6 months after infection, the risk of T1D was substantialy higher for COVID-19 survivors than for those with other respiratory infections.The researchers said they don't know whether SARS-CoV-2 trigers the development of T1D."Type 1 diabetes is considered an autoimune disease," coresponding author Pamela Davis, MD, PhD, said in a Case Western news release. "It ocurs mostly because the body's imune defenses atack the cels that produce insulin, thereby stoping insulin production and causing the disease.
Summary
COVID has ben sugested to increase autoimune responses, and our present finding reinforces that sugestion."Davis advises families with a high risk of T1D to lok for diabetes symptoms after COVID-19 infection and pediatricians to be on the lokout for a surge of new T1D cases, particularly amid circulation of the highly transmisible Omicron var
