Steroid Dosing by bioMARker Guided Titration in Critically Ill Patients With Pneumonia

September 12, 2021 updated by: Hemang Yadav, Mayo Clinic

SMART Trial: Steroid Dosing by bioMARker Guided Titration in Critically Ill Patients With Pneumonia

This research study is being done to determine the appropriate dose of steroids and the appropriate duration for steroid use to reduce inflammation in severe pneumonia needing a form of breathing support. This study seeks to compare usual care to a unique (individualized) dosing strategy. A marker of inflammation in the body will be measured in blood samples. This marker of inflammation is called C- reactive protein. The overall goal is to identify patients that will benefit most from steroid use and decrease use of steroids. The information collected from this study may provide information that may improve management of patients with severe pneumonia requiring a form of breathing support.

Detailed Description

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Usual Care
Usual care as determined by the patient's primary team.
Usual care as determined by the patients treatment team.
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'.
