![]() Mura calls this “weaving a story” based on the data. Data scientists like Mura and Bourne perform extensive detective work for medical analyses like this one, looking at existing information and drawing upon biochemical and molecular principles to propose a cohesive theory that helps elucidate the population-scale patterns they identify. The next challenge was to figure out why. It also seems to hinder the severity of disease progression, making patients less likely to reach the point where they require intubation or a ventilator. When delivered at high doses (the equivalent of about 10 Pepcid tablets), famotidine appears to improve the odds of survival for COVID-19 patients, especially when it is combined with aspirin. ![]() The team’s analysis, which appeared in the journal Signal Transduction & Targeted Therapy (from the Nature publishing group), showed that the data supported findings from other smaller-scale studies. “The power of the electronic health record, which is really yet to be fully realized as a research tool, is that you’ve suddenly got all this data you can mine to see whether what you determined in passing or anecdotally has any basis,” Bourne said. The team winnowed that number down to around 22,000 people, the largest sample size for a study on famotidine and the disease to date. Bourne and UVA senior scientist Cameron Mura worked with an international team of researchers to analyze information from a database that holds the medical records of millions of COVID-19 patients living in 30 different countries. When faced with a global pandemic, it’s helpful to explore other options. But this method is expensive and can take years, Bourne pointed out. Typically, to find out whether a drug is effective in treating a particular medical condition, scientists develop prospective clinical trials. “There’s often a phenomenon that doctors report anecdotally, or that’s mentioned in passing in a particular research paper, and that provides a clue - a hook,” he said. This is how many medical studies begin, said biomedical engineering professor Phil Bourne, who serves as founding dean for the School of Data Science. Was an over-the-counter acid suppressant helping people survive COVID-19? (Wealthier patients tended to take the more costly drug omeprazole, found in Prilosec.) Many of the elderly patients who survived the virus were poor: not exactly the demographic you would expect to fare well in a health crisis.Ī review of the survivors’ medical records revealed that a significant number suffered from chronic heartburn and were taking an inexpensive drug called famotidine, the key ingredient in Pepcid. In the early days of the COVID-19 pandemic, doctors in Wuhan noticed something surprising.
