Metadata about: In trying to understand the biochemical mechanism involved in the recent pandemic COVID-19, there is currently growing interest in angiotensin-converting enzyme II (ACE2). Nevertheless, the attempts to counteract COVID-19 interference with this enzymatic cascade are frustrating, and the results have thus far been inconclusive. Let's start again by considering the involved factors in an alternative way: we could postulate that COVID-19 could be more aggressive/fatal due to a high level of “basal” inflammation with low Nitric Oxide (NO) levels in hypertensive, diabetic and obese patients. Interestingly, the “protective” effects of several factors (such as estrogens) may play a role by increasing the formation of endogenous NO. From a therapeutic point of view, phosphodiesterase type 5 inhibitors such as oral Tadalafil, could be used in order to increase the basal NO levels. In this way, we don't fight the virus, but we may be able to mitigate its effects.
