ABSTRACT
INTRODUCTION:
The prevalence of post-viral olfactory dysfunction has increased significantly during the COVID-19 pandemic, posing a major challenge for patients and practitioners. While olfactory training (OT) is a common approach to therapy, there has been increasing interest in supplementing therapy with a combination of palmitoylethanolamide (PEA) and luteolin (LUT), which are known for their anti-inflammatory properties. In this study, their efficacy in the treatment of patients with olfactory loss following upper respiratory tract infections, mainly COVID-19, was investigated in an outpatient clinic.METHODS:
Fifty patients with persistent olfactory dysfunction were randomized to two groups one receiving OT and PEA-LUT, the other OT alone. Olfactory function was evaluated before and after treatment.RESULTS:
The study group showed significant improvements in odor discrimination and overall olfactory function (TDI score) after treatment with PEA-LUT and OT, while the control group did not. However, when clinically meaningful improvements were considered, there was no significant difference between the groups.CONCLUSION:
The present study suggests that while PEA-LUT may have the potential to improve olfactory function in post-viral dysfunction, the additional benefit over OT alone may be limited. These results contrast with some previous studies.
