What COVID-19 therapy is the real “Game-Changer”?
— Hydroxychloroquine or Zinc?

There has been a tremendous amount of buzz regarding the use of hydroxychloroquine (HC) for the treatment of COVID-19. This has been touted as everything from a “game-changer” and “a gift from God” to begin mostly dismissed for lack of convincing evidence. The skeptics, me being one, have cited the majority of the literature demonstrating negative outcomes. Nonetheless, the pressure to forego formal clinical trials and urgently employ the drug in the face of many impending deaths of an epidemic has been enormous and completely understandable.
A survey reported 2 days ago of doctors around the world who have been managing COVID-19 patients place it as “the most effective coronavirus treatment” to date. The survey, conducted by Sermo, a global health care polling company, asked 6,227 physicians in 30 countries to find out what is the most effective against SARS-CoV-2.
That is to say, of 6,000+ doctors surveyed, 37% considered HC the most effective available. This begs the question what the other 63% considered more effective than HC and it also seems to highlight the sorry state of what we have available as treatment since the therapy considered most effective has mostly shown no beneficial effect in the small clinical trials conducted to date. They didn’t report all the breakdown of how the voting went and which were the other 14 drug choices these doctors were allowed to choose from, but it likely included the antivirals remdesivir, lopinavir, and ritonavir.
Aside from these clinical trials of various quality and weak or negative outcomes, there have been two recent striking clinical observations by clinicians that have played powerfully in the media because of the obviously striking outcomes. These are not clinical trials but rather anecdotal observations of larger populations of patients treated for presumed COVID-19 infections and they did not involve just hydroxychloroquine alone. But just because they are not rigorous clinical trials shouldn’t mean we should discard any clinical benefit that is so obvious that we don’t need a statistical analysis to reveal it particularly if corroborating reports are coming in from multiple observers.
The first one was reported by Dr. Vladimir Zelenko from Monroe, NY whereby he reported on March 21 that his team had seen about 900 patients with possible coronavirus symptoms, treating about 350 with his regimen of HC, azithromycin and zinc. None had died as of April 2nd, he said, though six were hospitalized and two were on ventilators. Despite the criticism that this was not a randomized controlled trial, still, if one can believe that the 350 patients did indeed mostly have coronavirus and can believe the numbers that this wasn’t such a bad outcome. Still, skepticism remained because of these lingering questions.
This morning, another such pronouncement was made. Dr. Anthony Cardillo of Los Angeles said he has seen very promising results when prescribing HC in combination with zinc for the most severely-ill COVID-19 patients. He did not report the dosages of either the hydroxychloroquine or the zinc.
Zinc as an anti-viral
Zinc is known to inhibit viral replication by a few mechanisms. The first is that zinc shuts down the very enzyme that the RNA virus needs to replicate itself inside the cell. It inhibits RNA-dependent RNA polymerase (RdRP).
