RESUMO
BACKGROUND: This study aims to evaluate the real-world effectiveness of regdanvimab on clinical outcomes in patients with mild to moderate coronavirus disease 2019 (COVID-19). METHODS: This retrospective observational study included 152 patients (89 received regdanvimab and 63 did not) diagnosed with mild to moderate COVID-19 between August 2021 and October 2021 and admitted to Armed Forces Goyang Hospital. We collected information on the use of regdanvimab, remdesivir, dexamethasone, and supplemental oxygen; symptom severity score (SSS); and laboratory test results. A linear mixed-effects model was used to test the effectiveness of regdanvimab usage on SSS and the results of laboratory tests. A multivariate logistic regression model was used to calculate the odds ratio (OR) for additional therapeutic options, such as remdesivir, dexamethasone, and supplemental oxygen. RESULTS: The patients who received regdanvimab were older, showed a higher rate of vaccination, and had a higher Charlson comorbidity index, initial body temperature, and percentages of pneumonia at admission. The use of regdanvimab showed no interactive effects on the SSS and laboratory findings. Older age, male sex, obesity, high initial body temperature, and the presence of pneumonia at admission were associated with increased ORs for the use of these additional treatments. The use of regdanvimab reduced the probability of requiring additional therapies such as remdesivir, dexamethasone, and oxygen supplementation by 90.3% (95% confidence interval (CI), 60.3-97.6), 85.8% (95% CI, 34.2-96.9), and 89.8% (95% CI, 48.3-98), respectively. CONCLUSIONS: Regdanvimab usage was well tolerated and was associated with a decreased probability of requiring remdesivir, dexamethasone, and oxygen therapy. However, changes in SSS were not significantly different by the drug usage.
RESUMO
The neurologic manifestations concerning coronavirus disease 2019 (COVID-19) are highly penetrated. Anosmia and ageusia are one of the common acute neurologic symptoms, which develop in the early stage of COVID-19. However, it is not reported that how immunosuppressive agents affect these symptoms. We report olfactory and gustatory dysfunctions in a patient with ankylosing spondylitis (AS) treated with etanercept during COVID-19. A 53-year-old female showing AS controlled with tumor necrosis factor-α inhibitor, etanercept, had been diagnosed with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, presenting cough and rhinorrhea. One month after diagnosis, she complained about hyposmia and hypogeusia two days before the seronegative conversion of SARS-CoV-2, which were confirmed by a neurological examination. We speculate that the etanercept may have delayed the development of olfactory and gustatory dysfunction in the patient.
