BACKGROUND: Tocilizumab, an IL-6 receptor antagonist, may prevent functional impairments in critically ill patients by attenuating the cytokine storm. This study investigated a potential effect of tocilizumab on preventing functional impairments in patients with severe coronavirus infection 2019 (COVID-19).
METHODS: In a multicenter prospective observational study, patients with COVID-19 ≥ 20 years requiring mechanical ventilation admitted to the intensive care unit between April 2021 and September 2021 and discharged alive were followed for one year. A self-administered questionnaire on sequelae and functional impairments was mailed in August 2022, and data were collected. A multivariate logistic regression was used to assess the impact of tocilizumab on physical function, mental health, and Long COVID.
RESULTS: Of 157 analyzed patients, 41 received tocilizumab. The tocilizumab group had more severe illness, but a lower prevalence of physical impairment (17.1 % vs. 23.3 %, p = 0.41) and mental disorders (19.5 % vs. 39.7 %, p = 0.009) than the non-tocilizumab group. The prevalence of Long COVID was higher in the tocilizumab group (92.7 % vs. 80.2 %, p = 0.06), whereas fatigue/malaise was significantly lower (19.5 % vs. 37.1 %, p = 0.039). Adjusted odds ratios (95 % confidence interval) for physical impairment, mental disorders, and Long COVID with tocilizumab were 0.70 (0.2-2.1), 0.40 (0.16-1.01), and 2.94 (0.7-12.3), respectively, with no significant difference.
CONCLUSIONS: Tocilizumab was associated with a lower prevalence of physical impairment and mental disorders at 1 year in patients with severe COVID-19. Furthermore, Long COVID had a weaker impact on physical and cognitive functions.
