The mechanism of peripheral blood lymphocyte decline in COVID-19 patients is not yet clear. However, one theory demonstrated that in the whole progression of COVID-19, the extensive activation of poly-ADP-ribose polymerase (PARP) may reduce the cellular NAD+ and dampen the adaptive immune system. So investigators presume that replenishing the NAD+ using nicotinamide as the precursor may improve the lymphocyte counts and boost the adaptive immune system. As a result, the study using nicotinamide as a kind of supportive therapy provide further evidence of their efficiency and safety in treating lymphopenia in patients with COVID-19.
