Patients treated with inhibitors or blockers of the renin-angiotensin-aldosterone system (RAAS), showed no increased risk to develop COVID-19, nor an increased risk to developed a more critical stage of the disease. Patients with COVID-19, at the time of hospitalization showed a high proportion of the presence of proteinuria and hematuria. Reports from Europe and the United States showed that patients with COVID-19, whom required intensive care unit care, had an incidence of acute kidney injury (AKI) of 20% to 40%, and its onset showed a temporal relationship to the initiation of mechanical ventilation. Pathological findings showed that the principal cause of the renal injury was the development of acute tubular necrosis. The surge of patients with COVID-19 and AKI, demanded extraordinary efforts from health systems, to provide specialized medical personal and equipment for dialysis ther...

During a short human evolutive period, there has been a marked increase in the oral intake of sodium and a reduction in the intake of potassium. In current urbanized societies the elevated oral intake of sodium has been linked to an increase in the prevalence of arterial hypertension and of the cardiovascular and cerebrovascular mortality. Recent investigations have also demonstrated sodium harmful effect over vital organs, independent of its action over blood pressure. In parallel, an increase in the oral potassium intake has shown an antihypertensive effect as well as antiinflammatory, anti-fibrotic and anti-oxidant effects. New physiological findings, along with epidemiological studies about the role of potassium in control of blood pressure, have stimulated the formulation of health policies towards a nutrition with less sodium and more potassium.
