Resolution of COVID-19 induced anosmia following treatment with ST266.

ABSTRACT:

Background

Persistent anosmia following COVID-19 disease affects a significant subset of patients. Symptoms of this olfactory dysfunction negatively impact patient quality of life, and effective treatments are lacking; therefore, novel therapies that restore the ability to smell have tremendous clinical potential.

Case report

A 46-year-old female enrolled in a phase I clinical trial to assess the safety of targeted intranasal administration of a novel acellular secretome therapy (ST266) in patients diagnosed as glaucoma suspects. The patient reported greater than one year history of loss of smell that started following a presumed positive case of COVID-19. Following a 28-day treatment course of bilateral intranasal administration of ST266, the patient had resolution of her long-standing anosmia.

Conclusion

This case demonstrates resolution of COVID-19-induced persistent anosmia after intranasal treatment with a novel acellular secretome therapy. Further studies are warranted to determine the potential of ST266 and its components to treat anosmia.

Project description:Background: This systematic review had three aims: i) to determine the frequency of anosmia (or other smell disorders) and dysgeusia (or other taste disorders) in COVID-19 patients; ii) to determine whether anosmia or dysgeusia are independently associated with COVID-19 diagnosis; and iii) to determine whether anosmia or dysgeusia are prognostic factors for impaired outcomes among COVID-19 patients. Methods: On April 20 th, 2020, we search MEDLINE, Embase, Global Health, Scopus, Web of Science and MedXriv. We used terms related to COVID-19, smell and taste disorders. We selected case series, cross-sectional, case-control and cohort studies. We included studies with COVID-19 patients describing their symptoms; studies that compared smell and taste disorders between COVID-19 patients and otherwise healthy subjects; and studies comparing smell and taste disorders between COVID-19 severe and mild/moderate cases. Because of methodological heterogeneity and the limited number of results, a qualitative synthesis is presented. Results: From 31 reports, we selected six (n=2,757). Six studies reported the proportion of smell and taste disorders among COVID-19 patients. Two reports studied whether smell and taste disorders were independently associated with COVID-19 diagnosis. No reports studied the association with impaired outcomes among COVID-19 patients. The frequency of anosmia ranged between 22%-68%. The definition of taste disorders varied greatly, with dysgeusia present in 33% and ageusia in 20%. People who reported loss of smell and taste had six-fold higher odds of being COVID-19 positive; similarly, anosmia and ageusia were associated with 10-fold higher odds of COVID-19 diagnosis. Conclusions: The frequency of smell and taste disorders is as high as other symptoms, thus, at least anosmia for which the definition was more consistent, could be included in lists of COVID-19 symptoms. Although there is promising evidence, it is premature to conclude that smell and taste disorders are strongly associated with COVID-19 diagnosis. Registration: PROSPERO CRD42020181308.
