COVID-19 Insights: Diabetes and COVID-19

Diabetes and COVID-19

Characteristics of and Important Lessons From the Coronavirus Disease 2019 (COVID-19) Outbreak in China

Chinese data till February 11th 2020
Case fatality rate (CFR)
Cardiovascular diseases: 10.5%
Diabetes: 7.3%
Chronic respiratory diseases: 6.3%
Hypertension: 6%
Cancer: 5.6%

Prevention steps to stay healthy

Diabetic patients are
More prone to dehydration due to elevated glucose. (As the kidneys throw the glucose out and in the process throw the water out as well.) So keep it controlled.
When A1C goes in 9-10 range then the risk of complications increases significantly.

What to do?
Wash hands
Wear mask
Get a flu shot
If you are insulin dependent then keep extra insulin at hand.
Keep your diabetes and hypertension well managed.

What happens to immune system in diabetes?

Chronic hyperglycemia causes blood vessel narrowing and damage leading to slower perfusion and nerve damage. Nerve damage occurs both because of poor blood supply to the nerves and the accumulation of glucose in the myeline sheath and damaging it.

High glucose levels impair neutrophil activity (innate arm.)
Cytosolic calcium increases in PMN cells. This in turn reduces their ability to phagocytose. It happens because high levels of calcium reduce the synthesis of ATP that in turn is needed for the cellular function.
Study showing that the hyperglycemia increases intracellular calcium:

PMN chemotaxis is also impaired.
Reduced complement response
Reduced leukocyte adherence to the blood vessels. Study mentioining endothelial dysfunction:
Reduced response to pathogens
Chronic hyperglycemia leads to acidosis which further reduces the activity of the immune system. (Study mentioning immune dysregulation with various acids:
Skin cells become less efficient and skin and urinary infections become common.

Additionally, the reduced carbohydrate metabolism causes increased fatty acids mobilization. This results in the vascular endothelium to become atherosclerotic. Resulting also, in the narrowing of the blood vessels and reduced perfusion.
High free fatty acids also cause high levels of reactive oxygen species. This in turn makes our tissues prone to easy damage.
FFA cause disruption of insulin responding mechanisms.
Inflammation caused by ROS leading to adipocyte insulin resistance and inflammation:

Hyperglycemia causes an increase of dicarbonyl production. Dicarbonyl in turn reduces the function of beta-definsins. That are necessary to kill pathogens.

Endocrine and metabolic link to coronavirus infection

MERS COV and diabetes
Comorbid diabetes results in immune dysregulation and enhanced disease severity following MERS-CoV infection

T Helper 17 cells that release IL-17alpha

Transforming growth factor beta (TGF-β), interleukin 6 (IL-6), interleukin 21 (IL-21) and interleukin 23 (IL-23) contribute to Th17 formation in mice and humans.

Vitamin D in turn severely impairs the production of the TH17 cells. Hence, reducing the proinflammatory behavior.

ACE2 activity is upgregulated in pancreas of the diabetic patients.

Binding of SARS coronavirus to its receptor damages islets and causes acute diabetes

Why Is Coronavirus a Bigger Worry for People With Diabetes?

Everything You Should Know About Coronavirus and Diabetes

Are people with diabetes more likely to get COVID-19?

How about DKA and complication?

What are the concerning signs?
Shortness of breath
Persistent pressure/pain in the chest
New confusion or inability to arouse
Bluish lips/tongue or face

High blood sugar means that cells have less sugar to function. This includes the immune cells. Hence, all cells become an easy target.

Third of coronavirus deaths in England's hospitals linked to diabetes

The NHS has found that almost a third of all coronavirus deaths in England's hospitals are linked to diabetes - with the highest risk for people with type 1 diabetes, who are three and a half times more likely to die from the virus than non-diabetics.


But the overwhelming majority of Covid patients with diabetes who have died are Type 2 diabetics. Their risk of dying is twice that of people without diabetes.

Factors like age and obesity, which are common in Type 2, make a significant difference.

COVID-19 & Diabetes by Dr V Mohan

#covid19 #covid2019 #coronavirus #diabetesprevention

Due to the present scare due to COVID-19 infection, many people with diabetes have been
contacting us asking whether people with diabetes are more prone to COVID-19. It is true
that the people with diabetes are prone to all infections. There is some emerging data to
suggest that people with diabetes are also more prone to COVID-19. Moreover, even in
those with infections like COVID-19, which leads to pneumonia, the chances of a secondary
bacterial infection complicating the viral pneumonia is also there. Hence, people with
diabetes should take particular precautions with respect to COVID-19, as they already have
a slightly immuno- compromised state.

What can be done to prevent COVID-19 infection?
What special precautions should people with diabetes take?

We learn that how we can prevent covid-19 infection from the diabetic patient. What special precaution we need to take to prevent covid2019 from diabetes.
