The team was also attended by a team of specialists from the Operative Unit of Phoniatrics and Audiology of the Ca ‘Foncello Hospital in Treviso, coordinated by Cosimo de Filippis, director of the School of Specialization in Audiology and Phoniatrics of the University of Padua. Cosimo De Filippis, one of the study managers, commented: “” The results obtained are preliminary, but their monitoring will help collect more data to offer correct information and therapeutic indications to patients “.
The expert also devoted himself to the study of a meta-analysis carried out on 1500 patients with Covid-19. This investigation has observed symptoms such as:
- sore throat
- stuffy nose
- sense of smell
- alteration of taste
This study confirmed the data from the research conducted on 417 patients. “The olfactory epithelium also houses nerve endings through which the virus could access the brain.” We are developing a project in collaboration with virologists, neurologists and neuroradiologists with the aim of identifying patients in whom this mechanism may have taken place.“ said the Filippis expert. Experts are studying various scenarios.
- In some patients, the virus could infect the olfactory system and reach the olfactory cortex of the brain.
- instead, other people are hit in the lungs by the droplets that breathe the air or with a shower mechanism in which the viral particles fall
- In fewer people, the virus affects more of the brain.
In addition to this study, there is another study, a project carried out by the Global Consortium for Chemosensory Research in which Sissa (International School for Advanced Studies) and institutions from 50 countries around the world also participate. Anna Menini della Sissa said: “We all have the experience of loss of smell and taste when we cool down.. However, from what has been seen so far, in patients with COVID-19 the loss of smell and taste is very peculiar. And we want to know more “. Here we also investigate why, how and how often. the coronavirus patients lose taste and smell. Clinically these problems are called: anosmia and ageusia.
Always Menini, on Salute.gov adds: “Through this study, we will work to better understand the origins of loss of smell and taste, how often they are in patients with Covid-19, and find out if there may be possible warning signs to identify the disease even in the absence of other symptoms, a feature that, if verified, would be very important in quickly identifying the possibility of virus infection. ” At Global Consortium for Chemosensory research you can contribute to the research, the questionnaire is anonymous and the data will be used for analysis and then published.
