The effects of ACE2 inhibitors in the new coronavirus (COVID-19), Dangerous in Diabetes Mellitus

The new coronavirus (COVID-19) is known to cause serious diseases with underlying disease such as acute kidney disease, diabetes, immunodeficiency, and obstructive airway disease.
Acute renal disease (HR = 3.23, 95% CI: 2.01 to 5.19),
Diabetes (HR = 2.07, 95% CI: 1.32 to 3.26),
Immunodeficiency (HR = 2.33, 95% CI: 1.29 to4.2),
Obstructive airway disease (HR = 2.13, 95 % CI: 1.06 -4.3),

Since ACE2 is the main infection receptor for SARS-CoV-2, the following group has performed statistical analysis based on data obtained from 617 patients on side effects of ACE inhibitors.

Side effects of ACE inhibitors are particularly severe in diabetes (HR = 3.51, 95% CI: 1.59 to 7.75).
In the figure below, DM=Diabetes Mellitus, ACE=0 means no ACE inhibitors, and ACE=1 means with ACE inhibitors.
