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, C-Reactive Protein (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).

Drug: Methylprednisolone
Methylprednisolone will be administered based on CRP-guided protocol outlined under 'Biomarker-adjusted steroid dosing'.

- Timely Initiation of Corticosteroids and Implementation of Biomarker-titrated Corticosteroid Dosing [ Time Frame: Within 30 days of enrollment in study. ]Number of eligible subjects to adhered to the timely initiation and daily corticosteroid treatment according to ESICM/Society of Critical Care Medicine SCCM clinical practice guideline (control group) or biomarker concordance (intervention group)
- Mortality [ Time Frame: 90 days ]Number of subject deaths
- Need for High Flow Nasal Cannula Oxygen [ Time Frame: Within hospitalization or 30 days of study enrollment (whichever is sooner) ]Number of subjects to need high flow nasal cannula oxygen
- Need for Noninvasive Mechanical Ventilation [ Time Frame: Within hospitalization or 30 days of study enrollment (whichever is sooner) ]Assessed by the number of participants that required noninvasive mechanical ventilation.
- Need for Invasive Mechanical Ventilation [ Time Frame: Within hospitalization or 30 days of study enrollment (whichever is sooner) ]Assessed by the number of participants that required invasive mechanical ventilation.
- Organ Failure [ Time Frame: Measured daily for approximately 5 days ]Organ failures measured by Sequential Organ Failure Assessment (SOFA). The overall score is based on 6 sub-scores respiratory system, neurologic system, cardiovascular system, hepatic system, coagulation, and renal system using an overall scale of 0-24, which 0=no organ failure, 24=complete organ failure.
- New Onset Cardiac Arrhythmias [ Time Frame: Within hospitalization or 30 days of study enrollment (whichever is sooner) ]Number of participants who develop arrhythmias identified by electrocardiogram or echocardiogram.
- Myocardial Injury [ Time Frame: Up to day +14 following study enrollment. ]Number of participants with evidence of myocardial injury determined by daily troponin peak and /or new diagnosis of Left Ventricular (LV) dysfunction (LVEF <40%) or new diagnosis of cor pulmonale
- Cardiovascular Dysfunction [ Time Frame: Within hospitalization or 30 days of study enrollment (whichever is sooner) ]Number of subjects with new and/or worsening right ventricle (RV)/left ventricle (LV) dysfunction
- Occurrence of 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.
- Occurrence of 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.
- Occurrence of 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.
- ICU Admission [ Time Frame: Within hospitalization or 30 days of study enrollment (whichever is sooner) ]Number of subjects admitted to the ICU
- Oxygen-free Days [ Time Frame: Within hospitalization or 30 days of study enrollment (whichever is sooner) ]Number of days subjects did not require oxygen assistance.
