RESUMO
The factors contributing to increased morbidity and mortality in SARS-CoV-2 infection are diverse, and include diabetes, obesity, Chronic Obstructive Pulmonary Disease (COPD), advanced age, and male sex. Although there is no obvious connection between these, they do have one common denominator-they all have a tendency towards lower urine pH, which may indicate a lower-than-normal tissue pH. Furthermore, it has been shown that lower pH has two important negative influences: 1) it enhances viral fusion via the endosomal route, thereby facilitating viral multiplication; and 2) it facilitates increased production of inflammatory cytokines, thereby exacerbating the cytokine storm. This paper discusses published literature on lower tissue/interstitial pH in those diseases/co-morbidities that are known risk factors of severe COVID-19, and hypothesize that small doses of baking soda could be a simple, cost-effective, and rapid method of reducing both morbidity and mortality in COVID-19 patients.
