Trial Evaluating the Efficacy of Local Budesonide Therapy in the Management of Hyposmia in COVID-19 Patients Without Signs of Severity

• Status: Completed
• Trial end date: 2021-06-25
• Target enrollment: 0
• Participant gender: All

Summary

The initial symptoms described in the first cases of COVID-19 were mainly fever and respiratory signs. Recently, there has been an increase in cases of hyposmia without associated nasal obstruction or rhinorrhea. Although we do not yet know the long-term consequences of COVID-19 on olfaction, there is evidence in the literature demonstrating that post-viral hyposmias are an important source of long-term olfactory disorders, impacting quality of life.

Usually, the treatment of viral hyposmias is based on local and/or general corticosteroid treatment combined with saline nasal irrigation at the onset of signs. Because of the possible development of severe forms of the SARS-Cov-2 infection, the French Society of Otorhinolaryngology has advised against treatment by corticosteroid therapy and nasal irrigation. However, as the virus is present in the nasal fossae on average for 20 days, persistent hyposmia at 30 days would probably result from an inflammatory or neurological damage to the nasal slits or olfactory bulb. Local treatment with corticosteroids could then be instituted from 30 days after the onset of symptoms of COVID-19 without risk of dissemination.

In persistent hyposmia other than chronic rhinosinusitis, the only treatment that has proven its efficacy is nasal irrigation associated with budesonide and olfactory rehabilitation. However, this drug does not have marketing authorisation in France for this indication.
