  • Scientists are investigating a possible increase in diabetes cases since the beginning of the coronavirus pandemic.
  • 2
  • Diabetes is a condition in which the body cannot control sugars in the blood.
  • 3
  • The scientists want to find out if COVID-19 has a connection with the increase or if it is a coincidence.
  • 4
  • A report from the Centers for Disease Control and Prevention recently examined two large U.S. insurance databases.
  • 5
  • The databases included information about new diabetes cases from March 2020 through June 2021.
  • 6
  • The study found that diabetes was more common in children who had had COVID-19.
  • 7
  • The report did not look at the difference between Type 1 diabetes, which usually starts in childhood, and Type 2, the kind tied to being overweight.
  • 8
  • Rates of both kinds of diabetes have risen in U.S. children in recent years.
  • 9
  • But reports from Europe and some U.S. hospitals suggest the rates may have increased more during the pandemic.
  • 10
  • Dr. Inas Thomas of the University of Michigan's C.S. Mott Children's Hospital said, "I think we're all a little worried."
  • 11
  • Her hospital has seen a 30 percent increase in Type 1 diabetes, compared with the years before the pandemic, Thomas said.
  • 12
  • It is not known how many of the cases had COVID-19 at some point,
  • 13
  • but the timing raises concerns that there could be a connection, she said.
  • 14
  • Type 1 diabetes develops when the pancreas, an organ near the kidneys, produces little or no insulin, a hormone that controls blood sugar.
  • 15
  • It is thought to involve an autoimmune reaction.
  • 16
  • That means the body's defense system attacks insulin-making cells in the pancreas.
  • 17
  • Patients must use manufactured insulin to deal with the condition.
  • 18
  • Experts have believed for a long time that some earlier infection may set off that autoimmune reaction.
  • 19
  • With COVID-19, "We don't know if it's a direct effect or some other factor that's not fully understood yet, but we are hoping that this trend may help us figure out the trigger for what causes Type 1 diabetes," Thomas said.
  • 20
  • At Rady Children's Hospital in San Diego, Type 1 diabetes cases jumped almost 60 percent during the first year of the pandemic, compared with the previous 12 months.
  • 21
  • Researchers recently reported the finding in the medical publication JAMA Pediatrics.
  • 22
  • Just two percent of those children had had active COVID-19.
  • 23
  • The report did not have information on any previous infections.
  • 24
  • But the sharp increase was striking and "clearly there's a lot more work to be done to try to answer why is this happening,″ said Dr. Jane Kim. She co-wrote the report.
  • 25
  • Type 2 diabetes mostly affects adults.
  • 26
  • It changes how the body uses insulin, leading to poorly controlled blood sugar.
  • 27
  • Causes are uncertain but genetics, too much weight, inactivity and unhealthy eating habits play a part.
  • 28
  • It can sometimes be treated or cured with lifestyle changes.
  • 29
  • Around the world, more than 540 million people have diabetes, including about 37 million in the United States.
  • 30
  • Most have Type 2 diabetes.
  • 31
  • Many more have higher than normal blood sugar levels, or prediabetes.
  • 32
  • Rising diabetes cases might reflect conditions involving pandemic restrictions.
  • 33
  • These could include delayed medical care for early signs of diabetes or unhealthy eating habits and inactivity in people already at risk for Type 2 diabetes.
  • 34
  • A diabetes center at Chicago's La Rabida Children's Hospital has seen an increase in prediabetes during the pandemic.
  • 35
  • Center co-director Rosemary Briars suspects long hours of online learning without physical activity played a part.
  • 36
  • Dr. Rasa Kazlauskaite is a diabetes specialist at Chicago's Rush University Medical Center.
  • 37
  • She said steroid drugs that are sometimes used to reduce inflammation in hospitalized patients with infections including COVID-19 can cause blood sugar increases leading to diabetes.
  • 38
  • Sometimes the condition goes away after steroids are stopped, but not always, she said.
  • 39
  • The physical stress of severe COVID-19 and other illnesses can also cause high blood sugar and temporary diabetes, she added.
  • 40
  • Developing evidence suggests that the coronavirus - like some other viruses - can attack insulin-producing cells in the pancreas.
  • 41
  • That process might cause at least temporary diabetes in some people.
  • 42
  • To learn more, scientists in Denmark are getting adults recently diagnosed with Type 1 diabetes to take part in a study.
  • 43
  • The study group includes some people who had COVID-19.
  • 44
  • Over time, the researchers try to find out whether the condition progresses faster in those who had COVID-19.
  • 45
  • Such a study could help show how or if the infection might affect the development of diabetes, said researcher Dr. Morten Bjerregaard-Andersen.
  • 46
  • He is a diabetes specialist at the Hospital of South West Jutland.
  • 47
  • "The theory is if you had COVID-19, then your own insulin production will be more compromised than if you weren't infected," Bjerregaard-Andersen said.
