New method to treat loss of smell due to Covid-19 infection

The researchers used platelet-rich plasma as a restorative therapy to regenerate olfactory cells. The process begins with dissolving plasma from the patient’s blood and then implanting it in the nose. The aim is to repair cells that may have been damaged by infected with Covid-19. The implantation process will be monitored for a minimum of 3 months.

Loss of sense of smell or change in sense of smell can cause loss of interest in eating and lead to problems health other. According to a study published in JAMA, about 1.5 million people in the US have experienced long-term loss of smell after being infected with Covid-19.

When infected with Covid-19, the virus does not actually attack the nerve cells that detect odors but attacks the supporting cells, lining the nasal cavity. According to Cell, infected cells die off as immune cells rush to that area to fight the virus. Inflammation of the cells prevents odor receptors from working properly.

Although the study is in its early stages, the participants showed an improvement in symptoms. “Fortunately, the symptoms Mine has improved dramatically. For the first time in a long time, I have hope that my life will return to normal,” said Nancy Damato, one of the patients participating in the study. Deseret News.

Scientists at Thomas Jefferson University said there are plans to expand the study and focus on patients with long-term loss of smell due to Covid-19, according to the report. Deseret News.
