The SARS-CoV-2 hyperinflammatory response is associated with high mortality. This
hypothesis suggests that a deficiency of nicotinamide adenine dinucleotide
(NAD(+)) may be the primary factor related to the SARS-Cov-2 disease spectrum and
the risk for mortality, as subclinical nutritional deficiencies may be unmasked
by any significant increase in oxidative stress. NAD(+) levels decline with age
and are also reduced in conditions associated with oxidative stress as occurs
with hypertension, diabetes and obesity. These groups have also been observed to
have high mortality following infection with COVID-19. Further consumption of
NAD(+) in a pre-existent depleted state is more likely to cause progression to
the hyperinflammatory stage of the disease through its limiting effects on the
production of SIRT1. This provides a unifying hypothesis as to why these groups
are at high risk of mortality and suggests that nutritional support with NAD(+)
and SIRT1 activators, could minimise disease severity if administered
prophylactically and or therapeutically. The significance of this, if proven, has
far-reaching consequences in the management of COVID-19 especially in third world
countries, where resources and finances are limited.
