Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To be included in the study, patients should be more than 18 years old, have a history of COVID 19 infection more than three months ago as confirmed by PCR test, have a post COVID parosmia, and have no history of systemic steroid administration over the last one month. History of previous nasal surgery, underlying systemic diseases (like diabetes mellitus, hypertension, or autoimmune diseases), and hypersensitivity to Ivermectin were the exclusion criteria for this study.
Patients of the study will be randomly and equally distributed between case and control groups using block randomization methods using 4 blocks each comprising 4 patients with 6 patterns for every block one of which was selected randomly using random numbers generated by Excel program. The case group will receive a 4 week course using Devarol S amp containing 200,000 units per 2 ml giving a concentration of 5,000 units per drop. The patients will receive two drops per nostril twice daily. The Control group will receive a 4 weeks course of local steroids in the form of budesonide (64 µg per puff in a dose of 1 puff for each nostril twice daily.
Assessment protocol:
Patients of the study will be assessed before and at the end of the treatment protocol with history taking to define the inclusion and exclusion criteria. Endoscopic examination of the nasal cavity will be performed to exclude any other intranasal pathology. The degree of parosmia will be assessed using a visual analog scale before and four weeks after treatment.
Outcome measures:
Primary outcome measures will include a comparison between the pre and post treatment values of visual analog scales of parosmia, and a comparison between case and control groups regarding the post treatment results whether no improvement, partial improvement, or complete improvement. Secondary outcome measures will include assessment of the side effects of Ivermectin nasal drops among the case group.
