The ACTIV4-a, ATTACC, & REMAP-CAP investigators will present the results of this multi-platform trial, in which critically ill adults were randomized to receive therapeutic anticoagulation with heparin or pharmacological thromboprophylaxis as per local usual care.The preprint of the main paper was published on March 12th in MedRxiv.

To date, it's been unclear how patients with severe COVID-19 requiring non-invasive respiratory support should be managed. With over 1200 patients, the UK RECOVERY-RS trial is now the largest global non-invasive respiratory support trial for COVID-19, and compares CPAP with high flow nasal oxygen with standard care.

This Brazilian 2x2 factorial trial will randomise ICU patients at moderate to high risk for death or AKI to receive a balanced crystalloid solution (Plasma-Lyte®) or 0.9% saline and to receive crystalloids by rapid bolus infusion (999 mL/h) or slow infusion (333 mL/h) whenever plasma expansion is needed.

The ACTIV4-a, ATTACC, & REMAP-CAP investigators will present the results of this multi-platform trial examining therapeutic & prophylactic anti- coagulation in patients with COVID-19. The interim analysis was released January 28th and is available via the link below.
Originally planned for CCR21, which became eCCR21, but delayed into the Spring, the long awaited results of the follow-up trial to the landmark targeted temperature management after out-of-hospital cardiac arrest is out soon. Is the avoidance of fever the critical aspect of TTM? The results are due very soon.
This massive 11,000 patient trial from Brazil was also scheduled for CCR21, but was unavoidably delayed due to the pandemic. Comparing Plasma-Lyte 148 with 0.9% saline, it's almost ready for release now and we're delighted to be hosting this major trial result later this Spring.
In a Brazilian two-centre, blinded RCT in 240 patients with moderate or severe COVID-19, Murai and colleagues reported that a single oral dose of 200 000 IU vitamin D3 did not significantly change the median (IQR) length of hospitalisation; vitamin D3 group, 7.0 (4.0-10.0) days, vs. placebo group, 7.0 (5.0-13.0) days; log-rank, P = 0.59; unadjusted HR, 1.07; 95% CI, 0.82-1.39; P = 0.62.

In 668 patients with acute myocardial infarction and a hemoglobin level between 7 and 10 g/dL, a red cell transfusion threshold of ≤8 g/dL was found to be non-inferior to a threshold of ≤10 g/dL, with the composite MACE outcome (all-cause death, stroke, recurrent myocardial infarction, or emergency revascularization) at 30 days occurring in 11% vs 14%, respectively.
In 715 patients undergoing cardiopulmonary bypass and randomised to a protocol-guided strategy, using stroke volume variation to guide the administration of bolus fluids, or to usual care fluid administration, until desedation or up to 24 hours, there was no difference in the primary outcome of ICU length of stay; (median/IQR) intervention group; 27.9 hr (21.8–53.5 hr) vs control, 25.6 hr (21.9–64.6 hr); p = 0.95.

In 432 ventilated adults with sepsis, randomised to receive IV sedation with either dexmedetomidine (0.2 to 1.5 μg/kg/hr) or propofol (5 to 50 μg/kg/min), there was no difference between groups in the primary outcome of days alive without delirium or coma during the 14-day intervention period; 10.7 vs. 10.8 days; OR, 0.96; 95% CI, 0.74 to 1.26; respectively. There were also no differences in secondary outcomes, including mortality.

In adult patients suffering a traumatic brain injury, with a GCS score of 4 to 8, and initial ICP ≥ 25 mm Hg, the implementation of long-term mild hypothermia group (34–35 °C for 5 days), in comparison with normothermia group at 37 °C, did not improve the proportion with a favorable outcome (OR 1·55, 95%CI 0·91–2·64; P = 0·105) or mortality (P = 0·111) at 6 months.

In a prospective study in 20 ICUs in 3 countries, amongst 631 patients who underwent continued monitoring after planned withdrawal of life-sustaining support, 14% of patients had a resumption of cardiac activity after a period of pulselessness. Just 1 percent were observed clinically. The longest period to resumption of cardaic activity was 4 minutes 20 seconds.

In a Danish led, international, multi-centre, randomised controlled trial trial in 2928 adults with acute hypoxaemic respiratory failure, targetting a PaO2 of 8 kPa, in comparison with 12 kPa, did not improve the primary outcome of 90-day mortality (42.9% vs 42.4%; adjusted risk ratio, 1.02; 95% CI, 0.94 to 1.11; P=0.64).

In a Brazilian randomised controlled trial involving 9 hospitals, the use of tocilizumab as a single intravenous infusion of 8 mg/kg plus standard care (n=65) versus standard care alone (n=64), resulted in suimilar levels of mechanical ventilation at day 15 (28% vs. 20; (odds ratio 1.54, 95% CI0.66 to 3.66; P=0.32).), respectively, and increased mortality (17% vs. 3%; odds ratio 6.42, 95% CI,1.59 to 43.2).

In a pre-print paper, the REMAP-CAP trial investigators have reported efficacy with interleukin 6 receptor anatgonists in critically ill patients with COVID-19. Hospital mortality was 28.0% (98/350) for tocilizumab, 22.2% (10/45) for sarilumab and 35.8% (142/397) for control.
Preprint January 7th
In 10,406 randomised patients, with 1873 reported deaths, there was no significant difference in the primary endpoint of 28-day mortality -18% convalescent plasma vs. 18% usual care alone; risk ratio 1.04 [95% confidence interval 0.95-1.14]; p=0.34.
Prof Peter Horby, Tweet, Jan 15th
Three large randomised controlled trials, ATTACC, @ACTIV4a, and REMAP-CAP, have, for futility, halted recruitment to their therapeutic anticoagulation arms in critically ill patients with COVID-19.
In this multi-centre, blinded Australian trial, 25 000 IU of nebulised heparin administered 6 hourly while invasively ventilated, did not significantly alter the primary outcome of functional outcomes (SF-36) at 60 days; survivors in the heparin group (n=97) mean 53·6 vs control 48·7; difference 4·9 [95% CI –4·8 to 14·5]; p=0·32).
In this trial PCT-guided antimicrobial treatment in sepsis was effective in reducing infection-associated adverse events like infections by multidrug-resistant organisms and Clostridioides difficile, as well as in-hospital and 28-day mortality.
