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.
