Abstract
BACKGROUND
Anosmia was one of the main symptoms of coronavirus disease 2019 (COVID-19). A psychiatric history (i.e., depression) may be an independent contributor to the risk of COVID-19 diagnosis, and COVID-19 survivors appear to have an increased risk of neuropsychiatric sequelae (bidirectional association).
AIM
To compare the rate of psychiatric disorder among post-COVID patients without anosmia vs patients with persistent olfactory complaints.
METHODS
We conducted a prospective case control study from March 2020 to May 2021. Patients recruited at the ENT department of Nice University Hospital had a subjective olfactory complaint (visual analogue scale) for over 6 wk and a molecular or CT-proven severe acute respiratory syndrome coronavirus 2 diagnosis confirmed by serology. Post-COVID patients without persistent olfactory disorders were recruited at the university hospital infectiology department. Psychiatric medical histories were collected by a psychiatrist during the assessments.
RESULTS
Thirty-four patients with post-COVID-19 olfactory complaints were included in the first group of the study. Fifty percent of the patients were female (n = 17). The group’s mean age was 40.5 ± 12.9 years. The control group included 32 participants, of which 34.4% were female (n = 11), and had a mean age of 61.2 ± 12.2 years. The rate of psychiatric disorder among post-COVID patients with olfactory complaints was significatively higher (41.7%) than among patients without (18.8%) (χ2 = 5.9, P = 0.015).
CONCLUSION
The presence of a psychiatric history may constitute a potential risk factor for the development of long COVID due to persistent anosmia. It therefore seems important to establish reinforced health monitoring after a COVID 19 infection in at-risk patients. Further prospective, translational, and collaborative studies are needed to extrapolate these results to the general population.
Core Tip: Our study reveals a significant association between a psychiatric history and persistent anosmia in post-coronavirus disease 2019 (COVID-19) patients. With a higher rate of psychiatric disorder observed in individuals experiencing long-COVID symptoms, our findings underscore the need for reinforced health monitoring of at-risk patients. This emphasizes the importance of considering psychiatric factors in the assessment and management of post-COVID-19 sequelae. This study will thus contribute to a broader understanding of the multifaceted impact of the virus on mental health.
