Evaluation of effects of chronic nasal steroid use on rhinological symptoms of COVID-19 with SNOT-22 questionnaire.

BACKGROUND

The benefits of corticosteroids for the treatment of COVID-19 infection are documented in the literature. The goal of the study is to compare the severity of rhinological symptoms of COVID-19 between patients with nasal steroid use (NSU) and the control group (CG) using the sino-nasal outcome test (SNOT-22) questionnaire.

METHODS

A face-to-face survey was conducted at a second referral state hospital between. Patients with a complete recovery from COVID-19 were included in NSU and CG groups. Two subscales of the SNOT-22 were filled by the patients. The frequency and duration of smell and taste loss and SNOT-22 scores were compared between the two groups.

RESULTS

Forty-seven patients were included in the study. Thirty-one patients were in CG and 16 patients in the NSU group. Twenty-four (51.1%) patients were females and 23 (48.9%) were males. The mean age was 41.4 ± 8.6 years. Olfactory dysfunction was detected in 12 (75%) patients in the NSU group, and 31 (93.3%) patients in the control group (CG). Gustatory dysfunction was seen in 10 (62.5%) patients in the NSU group and 24 (77.4%) patients NSU group. (p = 0.071, 0.279, respectively). The duration of the olfactory (6.6 ± 2.5 days) and gustatory dysfunction (6.1 ± 2.6 days) and the mean SNOT-22 total score (11.9 ± 1.6) was significantly lower in the NSU group (p < 0.001, CI 11.1-5.1, CI 9.9-4.6, CI 9.3-5.9, respectively).

CONCLUSIONS

Although nasal steroid use does not prevent olfactory and gustatory dysfunction in COVID-19 patients, it may reduce the severity and duration of these symptoms.
