Diabète sucré et COVID-19

The majority of data indicate that COVID-19 infection in diabetic patients is no more prevalent than in the nondiabetic population. Acute metabolic complications such as diabetic ketoacidosis or hyperosmolality are common either in onset of new cases of type 2 diabetes or in preexisting diabetes. Factors influencing the prognosis of infection include advanced age, poor glycemic control aggravated by COVID19 induced by insulin resistance, co-morbidities such as obesity, hypertension, cardiovascular and renal complications. Furthermore, the "cytokine storm" can induce multi-visceral failure, in type 1 diabetics (T1DM) or type 2 diabetics (T2DM). Insulin therapy should be the treatment for patients with severe or critical conditions. The role of education should not be overlooked and patients and practitioners should be well informed about the universal COVID-19 infection prevention rules as well as some advice specific to diabetes mellitus (good glycemic control, increased selfmonitoring of blood glucose, maintenance of monitoring and availability of treatment).
