Background Limited data are available regarding antiviral therapy efficacy in most severe patients under mechanical ventilation for Covid-19-related acute respiratory distress syndrome (ARDS). Methods Comparison of antiviral strategies (none, hydroxychloroquine (OHQ), lopinavir/ritonavir (L/R), others (combination or remdesivir) in an observational multicentre cohort of patients with moderate-to-severe Covid-19 ARDS. The primary endpoint was the number of day 28 ventilator-free days (VFD). Patients who died before d28 were considered as having 0 VFD. The variable was dichotomized into “patients still ventilated or dead at day 28” versus “patients weaned and alive at day 28”. Results We analyzed 415 patients (85 treated with standard of care (SOC), 57 with L/R, 220 with OHQ, and 53 others). The median number of d28-VFD was 0 (IQR 0–13) and differed between groups (P = 0.03), SOC patients having the highest d28-VFD. After adjustment for age, sex, Charlson Comorbidity Index, PaO2/FiO2 ratio and plateau pressure and accounting for center effect with a generalized linear mixed model, none of the antiviral strategies increased the chance of being alive and weaned from MV at day 28 compared to the SOC strategy (OR 0.48 CI95% (0.18–1.25); OR 0.96 (0.47–2.02) and OR 1.43 (0.53–4.04) for L/R, OHQ and other treatments, respectively). Acute kidney injury during ICU stay was frequent (55%); its incidence was higher in patients receiving lopinavir (66 vs 53%, P = 0.03). After adjustment for age, sex, BMI, chronic hypertension and chronic renal disease, the use of L/R was associated with an increased risk of renal replacement therapy (RRT). (OR 2.52 CI95% 1.16–5.59). Conclusion In this multicentre observational study of moderate-to-severe Covid-19 ARDS patients, we did not observe any benefit among patients treated with OHQ or L/R compared with SOC. The use of L/R treatment was associated with an increased need for RRT. Take home message Neither hydroxychloroquine nor lopinavir/ritonavir as COVID-19 antiviral treatment is associated with higher ventilator-free days at day 28 when compared with standard of care (no antiviral treatment) in ICU patients under invasive mechanical ventilation. Lopinavir/ritonavir is associated with an increased risk of renal replacement therapy requirement. Tweet COVID-19: Insights from ARDS cohort: no signal of efficacy of any antiviral drugs. Lopinavir/ritonavir may be associated with need for RRT
Background Venovenous extracorporeal membrane oxygenation (VV-ECMO) is associated with a significant morbidity. There is the need to investigate long-term cognitive outcome among ARDS survivors treated with VV-ECMO. We aimed to compare the prevalence of long-term cognitive dysfunction and neuropsychological impairment using a highly specific test in severe ARDS survivors treated or not treated with VV-ECMO. Methods Severe ARDS survivors treated between 2011 and 2017 in an ECMO Regional Referral Center were prospectively evaluated 2 years after their ICU discharge. Patients underwent an in-person interview and examination. The primary outcome was cognitive function, assessed by the Wechsler Adult Intelligence Scale 4th edition (WAIS-IV). Secondary outcomes included anxiety, depression, post-traumatic stress disorder (PTSD) and quality-of-life. Results We investigated 40 consecutive patients surviving from severe ARDS treated ( N = 22) or not ( N = 18) with VV-ECMO at a median [interquartile range] of 20 [17–22] and 22 [18–23] months after ICU discharge, respectively. Regarding the main outcome, cognitive function was below normal ranges in 12 (55%) ECMO patients and 10 (56%) non-ECMO patients ( p = 0.95). Eight (36%) ECMO patients had moderate-to-severe depressive symptoms as compared with 7 (39%) non-ECMO patients ( p = 0.87). Twelve (55%) ECMO patients and eight (44%) non-ECMO patients had moderate-to-severe anxiety symptoms ( p = 0.53). Seven (33%) ECMO patients and eight (44%) non-ECMO patients presented a PTSD ( p = 0.48). Health-related quality of life did not differ between the two groups. Conclusions Using the WAIS-IV, VV-ECMO treatment does not appear to worsen long-term cognitive and neuropsychological outcomes in severe ARDS patients.
