BRONX, N.Y., July 22, 2020 /PRNewswire/ -- A new study led by Albert Einstein College of Medicine and Montefiore Health System confirms the findings of the large scale British trial of steroid use for COVID-19 patients and advances the research by answering several key questions: Which patients are most likely to benefit from steroid therapy? Could some of them be harmed? Can other formulations of steroids substitute for the agent studied in the British trial? The research was published today in the Journal of Hospital Medicine.

The U.K. RECOVERY trial, a prospective, randomized, open-label study of the steroid dexamethasone versus standard of care, involved more than 6,000 patients with COVID-19. Dexamethasone reduced deaths by about one-third in patients on ventilators and by about one-fifth among people who needed oxygen but were not on ventilators. However, the study leaves questions about the use of steroids for treating some patients.

"Our study is consistent with the promising findings from Britain, but for the first time, we are able to demonstrate that people can see the same life-saving benefits with steroid formulations other than dexamethasone," said Marla Keller, M.D., vice chair for research in the department of medicine at Einstein and Montefiore and lead author of the study. "We also found that a common blood test may identify the best candidates for steroid treatment." Dr. Keller is also professor of medicine and of obstetrics & gynecology and women's health at Einstein and an infectious disease specialist at Montefiore.

Authors of the Einstein-Montefiore study compared outcomes for two groups selected from nearly 3,000 people hospitalized at Montefiore with a positive COVID-19 test. One group of 140 patients was treated with steroids within 48 hours of hospital admission; and a control group of 1,666 similar patients did not receive steroid therapy. Most of the patients who received steroid therapy received prednisone. Some received dexamethasone and methylprednisolone.

Nearly all patients initially had a blood test to measure levels of C-reactive protein (CRP), which the liver produces in response to inflammation. The higher the CRP level in the blood, the greater amount of inflammation. A normal CRP level reported in the study is below 0.8 milligrams per deciliter of blood.

"We found that in patients with high levels of inflammation, namely a CRP level greater than 20, steroids were associated with a 75% reduction in the risk of going on mechanical ventilation or dying," said Dr. Keller. "Critically, we also found that for patients with a lower level of inflammation – CRP levels less than 10 – steroid use was associated with an almost 200% increased risk of going on mechanical ventilation or death."

A large percent of the people who succumb to COVID-19 die from the body's intense inflammatory response, which can overwhelm and severely damage the lungs. "Our findings suggest that steroid therapy should be reserved for people with high inflammation, as indicated by markedly elevated CRP levels," said William Southern, M.D., M.S., professor of medicine and chief of the division of hospital medicine at Einstein and Montefiore and the study's senior author. "It's a different story for people who do not have significant inflammation: for them, any benefit is outweighed by the risks from using steroids."

Study co-author Shitij Arora, M.D., associate professor of medicine at Einstein and a hospitalist at Montefiore, noted that the Einstein-Montefiore study included approximately equal numbers of male and female patients. In addition, nearly 40% of patients studied were Black and 36% were Hispanic. "The demographic diversity of the patients in this study suggests that steroid therapy benefits hospitalized COVID-19 patients affected by significant inflammation regardless of their race or ethnicity," he said.

The title of this paper is "Effect of Systemic Glucocorticoids on Mortality or Mechanical Ventilation in Patients With COVID-19." Other Einstein and Montefiore authors were Jen-Ting Chen, M.D., M.S., Elizabeth Kitsis, M.D., M.B.E., Shivani Agarwal, M.D., M.P.H., Michael Ross, M.D., and Yaron Tomer, M.D.
