It is worth discussing the interesting correlation between the increased mortality in COVID-19 patients with diabetes (12–22%) and hypertension (23.7–30%) [81,82,83,84] and the increased expression of Gal3 in prediabetic, diabetic, and hypertensive patients in the blood serum, lungs, alveolar cells, and respiratory tract mucus [16,85,86,87,88]. The gene discussed is LGALS3; the disease is COVID-19.
