Kiel: Covid 19 disease triggers diabetes

Kiel. Diabetes after a corona infection – German researchers report on such a case in the specialist journal “Nature Metabolism”. “A 19-year-old patient came to the clinic with newly developed severe diabetes with insulin deficiency. It turned out that he had apparently gone through an asymptomic infection with Sars-CoV-2 a few weeks earlier, ”explained Matthias Laudes from the Christian-Albrechts-Universität zu Kiel (CAU). Researchers from Munich and Dresden were also involved in the work.

The proven type 1 diabetes is usually triggered by an autoimmune reaction in which the immune system mistakenly considers the beta cells in the pancreas to be foreign and attacks them. “But this patient did not have this autoimmune reaction,” said Laudes. “We assume that the Sars-CoV-2 virus itself attacked the beta cells here.” The then disturbed insulin production then led to diabetes.

The young man received intensive care for three days. After a total of ten days, he was able to leave the hospital.

No signs of diabetes before Covid-19 infection

The young man came to the hospital emergency room within a few weeks with exhaustion, extreme tiredness and a weight loss of twelve kilos. He suffered from acute hyperglycemia. There was no history of type 1 diabetes in the 19-year-old’s history, but it could also have been undetected. In the family environment, one of the patient’s cousins ​​has type 1 diabetes, while the maternal grandmother was diagnosed with type 2 diabetes.

The doctors emphasize, however, that their observations are no reliable evidence that the infection was the trigger for diabetes in the 19-year-old. It is also conceivable that the young man already had undetected diabetes before he became infected with Sars-CoV-2. But he had no symptoms. Further analyzes of the possible connection between Covid-19 and the onset of diabetes are necessary for clarification.

Nonetheless, they recommend paying special attention to patients with diabetes who contract Covid-19 and paying more attention to diabetes symptoms in those infected with Covid-19.
