ABSTRACT
The aim of this study was to evaluate the usage of mometasone furoate nasal spray in the recovery of patients with severe microsmia or anosmia induced by COVID-19. This was a prospective clinical trial on non-hospitalized adult patients with COVID-19 (>18 years) who had severe microsmia or anosmia within two weeks. The subjects were randomly assigned to the mometasone furoate group (100 mcg twice daily) or sodium chloride group (0.9%); both groups also received olfactory training for 4 weeks. The primary outcome was the improvement of the olfactory score at the end of the study. Visual analog scale (VAS) and the University of Pennsylvania Smell Identification Test (UPSIT) were used to assess primary outcome. A total of 80 patients were recruited, 77 of them completed the study and were analyzed. There was no statistically significant difference in terms of demographics and baseline clinical characteristics. The olfactory scores (based on VAS) at weekly intervals showed a significant difference between the two groups (P0.318, <0.001, <0.001, <0.001, respectively). The analyses also showed significant within-group differences from baseline. Nevertheless, the changes were not significant between the two groups (P 0.444, 0.402, 0.267, 0.329). There was no significant difference between the two groups in terms of the UPSIT results (p > 0.239). However, a significant between-group difference was noted in the severity of loss of smell (P < 0.001). Compared to olfactory training, mometasone furoate nasal spray combination with olfactory training showed a higher improvement in severe chronic anosmia by COVID-19.
