In Search of a Neurotologic Profile in COVID-19 — A Study in Health Care Workers

Abstract

Introduction COVID-19 is an emerging disease and the neurotologic symptoms are still not well understood. Furthermore, the development of a neurotological profile and its associated factors can help the clinician in the diagnosis and treatment of this disease. The objective is to determine the neurotologic manifestations experienced by COVID-19 positive health care workers and their associated factors. Methods A symptoms survey was administered to health care workers who were positive to COVID-19 from September to October 2020. An informed consent form was digitally signed and Google Forms software was used for the survey. Frequencies and percentages were used for categorical variables, and associated clinical features were reported with odds ratios. Results We included 209 COVID-19 positive health care workers, 55.5% (n = 116) were women, and 44.5% (n = 93) were men. Fifty-three percent of patients were 20 to 30 years old and 56.4% had at least one comorbidity. The prevalence of neurotological manifestations was 18.6% (n = 39/209), the most frequent symptoms were vertigo (61.5%, n = 24/39), tinnitus (43.5%, n = 17/39), imbalance (43.5%, n = 17/39), and one case of facial paralysis (2.5%, n = 1/39). Neurotological manifestations were associated predominantly with asthenia (p = 0.021), loss of smell (p = 0.002) and taste dysfunction (p = 0.002). Conclusion The most common neurotological manifestations were vertigo, tinnitus and imbalance. Clinical features associated with a neurotologic profile were asthenia, hyposmia and dysgeusia.
