Covid-19: UAE doctors warn about link between diabetes, virus infection

Dubai - Studies have reportedly confirmed that coronavirus can target and weaken the body's insulin-producing cells

Doctors in the UAE are warning that there is emerging evidence pointing towards a relationship between diabetes and acute Covid-19 infection.

Two new NIH-supported studies reportedly confirm that SARS-CoV-2 can target and weaken the body’s insulin-producing cells.

The latest findings build on earlier studies done to discover more about the connection between Covid-19 and diabetes.

Dr Anil Kumar, consultant endocrinologist and diabetologist, Prime Hospital, says, “There is plenty of evidence to suggest that coronavirus might cause diabetes in some people or worsen pre-existing diabetes in others. I have seen a recent increase in referrals with new onset of diabetes mellitus in Covid-19 infected patients.”

He adds, “Cases of new diabetes diagnoses in coronavirus patients can be due to multiple reasons. One possible reason could be due to insulin resistance (insulin ineffectiveness) by an increase in inflammation inside the body caused by coronavirus. Another potential explanation could involve the expression of ACE-2 in the pancreas. This is the protein on the surface of cells that the coronavirus uses to enter and infect them. When coronavirus locks to ACE-2, the cells in the pancreas might not be able to do their normal releasing of insulin and processing glucose. It could accelerate progression towards a fresh onset of diabetes or bring to light already existing type 2 diabetes mellitus.”

Though a lot of information about coronavirus and its course of action have been studied and presented through scientific journals – there are many unknown facts as well.

Medics aver the latest is a study that indicates that even people without a history of diabetes could be affected.

Dr Rajesh Kumar Gupta, specialist internal medicine, Burjeel Specialty Hospital, Sharjah, said, “I have also noticed hyperglycemia in patients with severe Covid-19 and the development of new-onset diabetes after recovery in almost half of my patients, especially pre-diabetics. Severe Covid-19 infection can trigger hyperglycemia, which leads to the development of new-onset diabetes in infected patients and worsening of sugar control.”

Initial studies focused on lung and cardiovascular manifestations, other organs such as kidney, pancreas, intestine and olfactory epithelia dysfunction were also affected in some patients.
