older diabetics most at risk

Diabetes is a co-morbidity factor for Covid-19 that was identified fairly quickly at the start of the epidemic. A study carried out in more than 50 hospitals with diabetic patients makes it possible to determine which profile is most at risk.

Since the beginning ofepidemic of Covid-19, diabetes is known to be a factor of comorbidity important with, among others, theobesity and thehypertension. But the term diabetes describes two pathologies very different: one is an autoimmune disease, it is type 1 diabetes, and the other is linked to food, it generally appears with age, it is type 2 diabetes .

To understand a little more precisely which diabetes is most at risk and which part of the population is most likely to contract a severe form of Covid-19, 51 French hospitals participated in the Coronado study (Coronavirus SARS-CoV-2 and Diabetes Outcomes) which took place during last March. The results of the study were published in the specialized magazine Diabetologia.

Type 2 diabetes is the most common

Over 1,300 patients HIV positive with Sars-CoV-2 and with a long diabetic passive or a diagnostic recent were considered in the Coronado study. Males make up 64.9% of the sample and the median age is 69.8 years. At the start of follow-up, the majority of patients, 907 people, were not being treated in the intensive care unit, the other 410 people were, with or without tracheal intubation. The doctors then gave an update on their state of health on the seventh day.

What is the diabetic profile of these patients?

The overwhelming majority, 88.5%, of those considered in the Coronado study suffer fromtype 2 diabetes. This diabetes, which is not dependent oninsulin, is characterized by hyperglycemia, i.e. a rate of sugar too high in the blood. It appears with age and occurs around 50 years of age. Conversely, type 1 diabetes concerns only 3% of the Coronado study workforce.

A combination of comorbidity factor

Unfortunately, type 2 diabetes is often associated with d’Other co-morbidity factors which makes people particularly fragile when faced with Covid-19: 77% of patients also suffer from hypertension and 51% of dyslipidemia, a rate of cholesterol too high in the blood. Finally, theBMI median of the patients is 28.4, which, by standards, corresponds to overweight.

Of the patients included in the study, 20.3% required tracheal intubation and mechanical ventilation. And 10.6% died before the seventh day, while the patients were hospitalized only 5 days after the onset of symptoms. These premature deaths mainly concern patients over 75 years of age. No one under the age of 65 with type 1 diabetes died during the study.

In conclusion, elderly men with long-standing type 2 diabetes and associated complications are particularly vulnerable to Covid-19.
