Study using vitamin A to improve olfactory impairment caused by COVID-19

On September 28, British experts announced that they are studying the possibility of using vitamin A nasal drops to improve the complete or partial loss of smell in COVID-19 patients.

This is a common symptom of people with COVID-19 or other viral infections and can last for weeks or even months after recovery.

The team from the University of East Anglia (UEA) carried out the 12-week trial, which involved volunteers who were COVID-19 patients. The volunteers were divided into two groups using vitamin A nasal drops or a placebo to compare results.

According to the UEA, earlier research in Germany has shown vitamin A to have "potential benefit" in the treatment of loss of smell. So, the UEA designed this new trial to evaluate the ability of vitamin A drops to help heal tissue inside the nose that has been damaged by the virus.

In the experiment, all participants were asked to smell specific smells like roses and rotten eggs, and during that time, brain images were taken.

Professor Carl Philpott, from UEA, explains that the scans will allow to determine if the nerves involved in the sense of smell have been healed and to determine the brain activity involved in scent recognition. different.

Professor Philpott said about one in 10 COVID-19 patients had an irreversible loss of smell four weeks after contracting the virus, and the main challenge facing patients and doctors today is the lack of effective treatments. This situation. Meanwhile, a study in Germany found that people treated with vitamin A improved their sense of smell twice as fast as those who didn't take the vitamin.

Loss of smell was already a serious problem before the pandemic, affecting about 5% of the population, but the outbreak has exacerbated the problem, the need to find effective methods. results are even more urgent.

Professor Philpott says the loss of the sense of smell is a big problem, indirectly leading to other problems such as depression, anxiety, altered taste and feelings of isolation. Not only that, people who have lost their sense of smell can be at risk in special circumstances, such as accidental gas leaks or ingestion of spoiled food.

Loss of smell is one of the typical symptoms of COVID-19, along with other symptoms such as loss of taste, fever, and persistent cough. Many COVID-19 patients have lost their sense of smell and although the number of those who fall into this condition has not been determined, there are some studies that indicate that the rate of COVID-19 patients who lose their sense of smell is up to 2/ 3. Some patients also have a disorder of smell, confusion of taste. While most COVID-19 patients will regain their sense of smell after recovering, there are those who still struggle with the condition for weeks, months, and even years after recovery. The condition is therefore also included in persistent symptoms of COVID-19.

Although loss of smell is thought to be much milder than the severe, life-threatening symptoms, the condition can have long-term consequences for life and can affect the senses. other, especially taste. There are still very few effective treatments for this condition in which steroid compounds are also used but have side effects and there is not much evidence the compound actually works.

Many doctors around the world recommend exercises to restore the sense of smell, such as regularly smelling strong odors such as coffee and garlic to stimulate brain activity related to the ability to perceive different odors.
