Stanford Health Care – Now
Nasal Injections Could Treat Long COVID-19 Smell Loss
04.01.2023
According to a 2022 survey by Patel and colleagues, about 15% of people who experienced smell loss from COVID-19 continued to have problems six months later. That’s roughly 9 million people in the U.S., and the number is growing. Many who report loss of smell also report loss of taste because smell is such a major component of how we experience food.
Now Patel’s team has tested a new treatment for long-term, COVID-19-related smell loss using injections of platelet-rich plasma derived from a patient’s own blood. In a trial of 26 participants, those who received the treatment were 12.5 times more likely to improve than patients who received placebo injections.
