CONCLUSIONS
Given the current absence of any gold-standard therapy for the treatment
of COVID-19 or its associated complications, multipotential drugs with
anti-inflammatory, antioxidant and anti-apoptotic properties could have
promising results if indicated or used in a proper setting. We designed
one of the best-designed RCTs to date to evaluate the efficacy and
safety of NAC in the treatment of patients with COVID-19. The salient
findings of this RCT were that at the end of the study, a further drop
in C-reactive protein was detected in the NAC group (P =0.008),
and no death occurred in the atazanavir/ritonavir + HCQ + NAC group,
indicating that the combination of these drugs may lessen mortality.
Moreover, the atazanavir/ritonavir + HCQ and atazanavir/ritonavir + HCQ
+ NAC groups had the highest O2 saturation at the end of
the study and a significant elevation in O2 saturation
after the start of the intervention, including NAC (P<0.05). In light of the findings of the present RCT, we can
conclude that oral or intravenous NAC, if indicated, may boost
O2 saturation, blunt the inflammation trend (by reducing
C-reactive protein), and decline mortality in hospitalized patients with
COVID-19. The NAC could be more effective as prophylactic or adjuvant
therapy in stable non-severe cases of COVID-19 with a particularly
positive role in the augmentation of O2 saturation and faster reduction
of the CRP level and inflammation.
