ABSTRACT
Aims: We assessed the effectiveness of early administration of corticosteroids in patients affected by COVID-19 with moderate to severe acute respiratory distress syndrome requiring oxygen support. Methods: This is a single-center, retrospective, controlled cohort study including patients admitted to our hospital from March 13th to April 20th, 2020. Patients received an intravenous bolus of 8mg dexamethasone twice daily for 5 days or standard care only. Clinical and laboratory characteristics were abstracted by medical records. The primary endpoint was clinical improvement, defined as an increase in the arterial partial pressure of oxygen/fraction of inspired oxygen ratio ≥50%, respiratory rate <24 breaths/min, and decrease in C-reactive protein (CRP) ≥50% compared to the baseline. The secondary endpoint was weaning from any ventilatory support. Outcomes were assessed using Kaplan-Meier analysis with Log-rank test and multivariable Cox regression. Results: Thirty-seven patients (21.6% female;mean age, 63.3±11.4 years) were identified who needed non-invasive mechanical ventilation, 23 of whom received steroids and 14 standard care. Median follow-up was 20 days (range 7-52). Treatment with dexamethasone was associated with faster clinical improvement than standard care [median days, 2 vs. 6;hazard ratio (HR), 3.28;95% confidence interval (CI), 1.64-6.55;P <.0001) and earlier weaning from ventilatory support (median days, 4 vs. 7;HR, 2.24;95% CI, 1.13-4.43;P =.014). CRP decreased over time only in patients on corticosteroids (treatment effect P <.001). Conclusion: In COVID-19 patients with moderate-to-severe ARDS the early use of dexamethasone prevented disease progression, resulting from host inflammatory response, and improved clinical outcome.
ABSTRACT
Background: To face the health emergency due to the first spread in Italy of COVID- 19, a nationwide lockdown was instituted from 9 March to 3 May 2020. During this period all the hospital outpatient activities were suspended except for urgent cases. Objective: To evaluate the cardiological urgent outpatient examinations done in our hospital during the lockdown in view of the reduced hospitalizations and the increased cardiovascular deaths observed during the COVID-19 outbreak. Methods: The urgent cardiological examinations (requests with priority U and B, i.e., to be done within 3 and 10 days respectively) performed during the 8-week period of lockdown (38 working days) were compared with those performed during the same period in the previous year (37 working days). During the lockdown and the control period, the availability of urgent cardiological visits was the same (2 per day with priority U and 2 per day with priority B). The number of cardiological examinations performed and the main characteristics of the subjects attending the outpatient clinic in the two periods were evaluated, comparing them with the chi-square test and considering as significant p values <0.05. Results: The table shows the number of urgent cardiological outpatient examinations done on those available in the two periods under comparison. Cardiological urgent outpatient examinations LOCKDOWN CONTROL Chi-square p • with priority U (performed/available) 41/76 (53.9%) 71/74 (95.9%) 34.96 <0.01 • with priority B (performed/available) 28/76 (36.8%) 69/74 (93.2%) 52.20 <0.01 The reduction in the number of urgent cardiological outpatient examinations done during the lockdown was observed from the first week with a nadir at the third and a subsequent slow return to normality at the end of eight weeks. No significant differences in age, sex, history of heart diseases, reasons and outcomes of the examinations were observed in patients evaluated in the two periods. Conclusion: During the first lockdown introduced in Italy to face the COVID-19 pandemic, a statistically significant reduction of accesses to the outpatient clinic for urgent cardiological examinations of our hospital was observed with possible negative consequences in the diagnosis and treatment of cardiovascular diseases in the community.
