In community acquired pneumonia, corticosteroids have been shown to have potential benefit. However, the limited and variable use of adjunctive corticosteroids in critically ill patients is largely due to an inability to identify patients that will benefit from the use of anti-inflammatory medications. This study compares usual care to a novel biomarker-tailored steroid dosing algorithm for patients with community acquired pneumonia.
In April 2020, in response to the SARS CoV-2 pandemic, we added a COVID-19 arm to this study. The study will evaluate the role of biomarker-titrated adjuvant corticosteroid administration compared to usual care in patients admitted to hospital with SARS CoV-2 (COVID-19) infection and acute respiratory failure.
|Condition or disease||Intervention/treatment||Phase|
|Pneumonia||Drug: Methylprednisolone Other: Usual Care||Phase 2|
This is a two-arm single-center pilot phase II clinical trial. Patients will be screened at the time of hospital admission and will be required to be enrolled within the clinical trial within 48 hours of hospital admission.
In the individualized, biomarker-concordant arm, all patients will receive steroids once at the time of admission, then a daily morning dose. In order to account for varying turnaround time at different laboratories, CRP levels will be drawn with early morning labs, and used to determine the steroid dosing for the day. Patients will receive daily CRP measurements for the first 5 days of the hospitalization, or until hospital discharge. CRP measurements will be discontinued once the CRP is less than 50mmol/L.
Steroid administration will be facilitated using standardized computerized physician order entry. The patients, treating physicians and outcome assessors will be blinded to the group assignment. Steroid order sets will include 6 hourly point of care glucose monitoring, and an insulin sliding scale for glucose levels to facilitate glucose management. The need for insulin drip will be determined by the treating physician. Additional testing including serum and urine ketones will be informed by the glucose level, serum anion gap and bicarbonate levels in routine basic metabolic panels and determined by the treating physician.
In the usual care arm, patients will receive daily CRP measurements for the first 5 days of the hospitalization, or until hospital discharge.

Experimental: Biomarker-adjusted Steroid Dosing
Individualized, biomarker concordant steroid use: dosing, titration and duration according to CRP level. This is a predetermined dosing table that adjusts dose of steroid by CRP level. Specifically: if CRP < 50 mmol/L: discontinue steroid; if CRP is between 51-100 mmol/L: 0.5 mg methylprednisolone (or dose equivalent of oral prednisone); if CRP is between 101-150 mmol/L: 0.75 mg/kg methylprednisolone (or dose equivalent of oral prednisone); if CRP level is between 151-200 mmol/L: 1 mg/kg methylprednisolone (or dose equivalent of oral prednisone); if CRP level > 200 mmol/L: 1.5 mg/kg methylprednisolone (or dose equivalent of oral prednisone).
Methylprednisolone will be administered based on CRP-guided protocol outlined under 'Biomarker-adjusted steroid dosing'.
- Feasibility of the timely initiation of corticosteroids and implementation of biomarker-titrated corticosteroid dosing: percentage of eligible patients adhered to the timely initiation [ Time Frame: Within 30 days of enrollment in study. ]A percentage of eligible patients adhered to the timely initiation (within 12 hours of emergency room admission) and daily corticosteroid treatment according to ESICM/SCCM clinical practice guideline (control group) or biomarker concordance (intervention group)
- Mortality [ Time Frame: Within 30 days and 90 days of study enrollment ]Death from any cause
- Progression of disease [ Time Frame: Within hospitalization or 30 days of study enrollment (whichever is sooner) ]Progression of disease is defined by the need for high flow nasal cannula oxygen, noninvasive or invasive ventilation. Given the proliferation of high flow nasal cannula oxygen use in lieu of mechanical ventilation, instead of ventilator-free days the investigators opt for using advanced respiratory support free days where "advanced respiratory support" includes both invasive and noninvasive mechanical ventilation and the high flow nasal cannula oxygen.
- Evolution of respiratory failure [ Time Frame: Within 72 hours of enrollment in study. ]Measured by respiratory component of SOFA at time of ICU admission, after 24 hours, after 48 hours and after 72 hours and by the organ failure free days. In the absence of daily arterial blood gas analysis, PaO2/FiO2 ratio will be replaced by SpO2/FiO2 ratio
- Evolution of kidney failure [ Time Frame: Within 72 hours of enrollment in study. ]Assessed by renal component of Sequential Organ Failure Assessment (SOFA) Score score. This is a scale from 0-4 (with 0 indicating no renal failure and 4 indicating severe renal failure).
- Evolution of shock [ Time Frame: Within 72 hours of enrollment in study. ]Assessed by cardiac component of Sequential Organ Failure Assessment (SOFA) Score score. This is a scale from 0-4 (with 0 indicating no cardiovascular failure and 4 indicating severe cardiovascular failure).
- Length of stay [ Time Frame: From time of study enrollment up to discharge from hospital, to a maximum of 1 year. ]In hospital and in ICU
- Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]: Hyperglycemia [ Time Frame: Up to day +5 following study enrollment. ]Number of participants who have hyperglycemia while receiving corticosteroids. Hyperglycemia is defined as a consistently elevated blood sugar level requiring insulin administration.
- Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]: Delirium [ Time Frame: Up to day +5 following study enrollment. ]Number of participants who develop delirium while receiving corticosteroids. Delirium will be assessed by Confusion Assessment Method for the ICU (CAM-ICU) measurement tool. The CAM-ICU is a binary (yes/no) scale for assessing the presence of delirium.
- Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]: Secondary Infection [ Time Frame: Up to day +14 following study enrollment. ]Number of participants who develop secondary infections during and after steroid therapy. A secondary infection is defined as a new infection that develops after initiation of corticosteroid therapy, until 5 days after steroids are discontinued.
