A Recent Study Identified The Reasons Why Some COVID-19 Patients May Never Regain Their Sense Of Smell

A new study has found that some COVID19 patients may never regain their sense of smell, even after their health has recovered from the virus. The research, conducted by a team of scientists at the University of Pennsylvania, is the first to investigate why some COVID19 patients have longterm olfactory dysfunction (LOFD).

The findings, published in the journal JAMA OtolaryngologyHead & Neck Surgery, suggest that the virus can damage sensory nerves in the nose, leading to permanent changes in smell. The study included 118 patients who had been admitted to the Penn Medicine Center for COVID19 Care between April and August 2020.

The participants completed a series of smell tests, which assessed their ability to identify various odors before and after their COVID19 infection. The researchers found that, of the 118 patients, 32 (27%) had LOFD, defined as a decrease in their ability to identify odors one month after their initial diagnosis.

The researchers also conducted a detailed analysis of the participants who had LOFD and found that their sense of smell loss was not related to age, sex, or duration of the infection.

Instead, the researchers found that the presence of certain genetic markers, including the ACE2 gene, which is known to be involved in the entry of coronavirus into human cells, was associated with a greater risk of longterm olfactory dysfunction.

The findings of this study suggest that some COVID19 patients may never regain their sense of smell, even if their health returns to normal. This is concerning, as loss of smell is a significant impairment that can have a negative impact on quality of life.

The researchers suggest that further research is needed to better understand the factors involved in longterm olfactory dysfunction and to develop interventions that can help COVID19 patients regain their sense of smell.

In conclusion, this study provides important insight into why some COVID19 patients may never regain their sense of smell. The findings suggest that the virus can damage sensory nerves in the nose, leading to longterm olfactory dysfunction.

The presence of certain genetic markers, such as the ACE2 gene, appears to be associated with a greater risk of this condition. Further research is needed to better understand the factors involved in longterm olfactory dysfunction and to develop interventions that can help COVID19 patients regain their sense of smell.

Overall, this study provides valuable information about why some COVID19 patients may never regain their sense of smell. The findings suggest that the virus can cause permanent damage to sensory nerves in the nose and that certain genetic markers can increase the risk of this condition.

The researchers suggest that further research is needed to better understand the factors involved in longterm olfactory dysfunction and to develop interventions to help patients regain their sense of smell. This research highlights the importance of continuing to investigate the longterm effects of COVID19 and developing strategies to help affected individuals.
