And this possible side effect of Covid-19 infection has been added to the multiple symptoms of the epidemic, according to the journal.
“Despite the extensive literature on Covid-19 and the various symptoms associated with the virus, there is a lack of discussion about the relationship between Covid-19 and hearing,” the specialists said.
They called for a hearing loss screening in the hospital, including intensive care as it is easily bypassed, to allow for prompt treatment with steroids that provide the best chance of restoring hearing.
So far, few other cases related to Covid-19 have been reported, as no case has been reported in the UK, according to these specialists.
Sudden hearing loss without causes
Ear, nose, and throat specialists often notice sudden hearing loss, at a rate of 5 to 160 cases per 100,000 cases each year. The reasons are not clear, but this sensory deficiency may be due, for example, to a vascular blockage
Hematologic, but also after a viral infection, such as influenza, herpes viruses, or CMV.
The report’s authors described the case of a 45-year-old man with asthma being treated for Covid-19 in their hospitals.
He was tied to a ventilator in the intensive care unit because he had difficulty breathing, and he began to improve after receiving treatment (remdesivir, intravenous steroids, blood plasma).
A week after his breathing tube was removed and he was discharged from resuscitation, he felt an abnormal ringing in his left ear, followed by sudden hearing loss.
After the examination, it was found that his ear canals were not blocked and not inflamed, and his eardrum was healthy. A hearing test confirmed hearing loss in his left ear from which he only partially recovered after treatment with a corticosteroid.
Other possible causes, such as influenza, HIV or rheumatoid arthritis, were ruled out, and doctors concluded that his hearing loss was linked to the epidemic.
The first case of hearing loss
In Thailand, the first case of hearing loss reporting COVID-19 alone was reported in April 2020.
The SARS-Cove-2 virus, which is responsible for Covid-19 infection, and is associated with a specific type of cells lining the lungs, has been detected in similar cells in the ear.
This virus also causes inflammation and an increase in the substances (cytokines) that lead to hearing loss, according to the authors.
