Doctors say their COVID-19 protocol saves lives; others want proof


 

Peer review

The physicians who reviewed MATH+ for Medscape Medical News differed on which parts of the protocol they support and which parts they would change.

Dexamethasone should be the corticosteroid of choice over methylprednisolone, says Cassiere, because it has now been proven effective in the randomized RECOVERY Trial, which also tested dosing and a timetable for treatment.

But Sam Parnia, MD, PhD, associate professor of medicine and director of critical care and resuscitation research at NYU Langone, thinks methylprednisolone may be effective, and that even higher doses over longer periods of time may stave off recurring pneumonia, based on his experience using the steroid to treat COVID-19 patients in New York.

“What I really like about this protocol is, these guys are very smart, they recommend the need to treat multiple different things at the same time,” says Parnia. COVID-19 is a complex condition, he notes: If physicians are only focused on solving one problem, like hypoxia, patients could still be dying from blood clots.

Despite general concerns about the protocol, Cassiere says he was excited about the inclusion of heparin. Given the extreme levels of clotting seen in COVID-19 patients, he would have included specific D-dimer levels to guide treatment and explored antiplatelet therapies like aspirin. Gong, however, cautioned that she had seen her patients on anticoagulants develop gastrointestinal bleeding, and reiterated the need for clinical evidence. (At least one clinical trial is currently testing the risks and benefits of heparin as an antithrombotic therapy for COVID-19 patients.)

Perhaps the most divisive part of the protocol is the inclusion of ascorbic acid. “That’s the civil war,” says Kory. “It’s the most polarizing medicine.” The authors of the MATH+ protocol were close colleagues before COVID-19 in part because of a mutual research interest in ascorbic acid, he says. Other physicians, including Cassiere, are extremely skeptical that ascorbic acid has any effect, citing recently published studies in the Journal of the American Medical Association that found ascorbic acid ineffective for treating sepsis.

The MATH+ creators say they are working on a literature review of the research behind the protocol, and they plan to write up the observational impacts of the protocol. Marik says he’s not optimistic about getting the findings published in a high-impact journal given the observational nature of the research; the relatively small number of patients treated at hospitals using the protocol (140 patients at Marik’s hospital in Virginia and 180 at Varon’s in Houston, according to Marik); and the vast number of COVID-19 papers being submitted to scientific journals right now.

“This is not a remedy with expensive designer drugs,” Marik said. “No one has any interest in treating patients with cheap, safe, readily available drugs.”

“I hope they’re right if they’re saying this combination of medicines dramatically decreases mortality,” says Taison Bell, MD, director of the medical intensive care unit and assistant professor of medicine at UVA Health in Charlottesville, Virginia.

But physicians have hurt patients in the past with medications they hoped would work, he says. “We have to make sure we’re balancing the risk and the harm with that benefit, and the only way to protect patients from those biases is by doing a randomized controlled trial.”
