Corticosteroids in Community Acquired Pneumonia
Study Details
Study Description
Brief Summary
This is a single-center, blinded, placebo-controlled pilot RCT evaluating corticosteroids for the treatment of Community Acquired Pneumonia (CAP) that will enroll 100 adults hospitalized with community-acquired pneumonia. The primary goal is to assess the feasibility of proposed trial procedures for use in a subsequent phase III trial powered on 6-month cognitive outcome (MOCA-Blind score). Key outcomes are six-month cognitive and functional status, duration and severity of symptoms, and mortality.

Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Prednisone Patients randomized to the intervention arm will receive prednisone 50mg PO daily for 7 days. |
Drug: Prednisone
Prednisone 50mg will be administered enterally for 7 days.
|
| Placebo Comparator: Placebo Patients will receive matching placebo PO daily for 7 days. |
Drug: Placebo
This is a matching placebo to prednisone.

Outcome Measures
Primary Outcome Measures
- Feasibility as determined by the number of subjects who are successfully recruited and complete follow-up [1.5 years]
Feasibility will be defined as: (a) recruitment and successful protocol completion of 100 patients; (b) corticosteroids being well tolerated, as shown by similar severity and frequency of adverse events in the intervention and placebo groups; (c) successful completion of 6-month cognitive assessments by >80% of survivors; and (d) the primary cognitive outcome Montreal Cognitive Assessment-Blind (MOCA-Blind) numerically favoring the intervention group with the one-tailed upper 80% confidence interval of the difference in MOCA-Blind between the intervention and placebo groups containing the minimally-important clinical difference (2 points on the MOCA-Blind).
Secondary Outcome Measures
- Global cognition as measured by the Montreal Cognitive Assessment-Blind (MOCA-Blind) [6-months]
This is a measure of global cognition based on the assessment of attention concentration, memory, language, conceptual thinking, calculations, and orientation. Scores range from 0 to 22 with higher scores indicating better cognition.
- Severity of pneumonia symptoms as measured by the Community-Acquired Pneumonia Symptom (CAP-Sym) Questionnaire [3-days]
This is a 18-item scale to determine the presence and severity of pneumonia symptoms. Each item is graded on a 6-point Likert scale. Scores range from 0 to 90 with higher scores indicating more severe symptoms.
- Severity of pneumonia symptoms as measured by the Community-Acquired Pneumonia Symptom (CAP-Sym) Questionnaire [7-days]
This is a 18-item scale to determine the presence and severity of pneumonia symptoms. Each item is graded on a 6-point Likert scale. Scores range from 0 to 90 with higher scores indicating more severe symptoms.
- Severity of pneumonia symptoms as measured by the Community-Acquired Pneumonia Symptom (CAP-Sym) Questionnaire [30-days]
This is a 18-item scale to determine the presence and severity of pneumonia symptoms. Each item is graded on a 6-point Likert scale. Scores range from 0 to 90 with higher scores indicating more severe symptoms.
- Quality of life as measured by the EQ-5D-5L [6-months]
Characterizes quality of life and contains 5-dimensions ("5D") related to everyday living: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. It asks patients to rate their current global health status from 0 (worst health you can imagine) to 100 (best health you can imagine). Scores range from -0.573 to 1.000 with higher scores indicating better quality of life.
- Basic activities of daily living (ADL) as measured by the Barthel's Index [6-months]
Quantifies pre-illness basic ADLs such as bathing, dressing, toileting, transferring, continence, and feeding. Scores range from 0 to 20 with higher scores indicating better functioning.
- Instrumental ADL as measured by Lawton Instrumental Activities of Daily Living Scale (IADLs) [6-months]
Quantifies pre-illness IADLs - ability to use the phone, shopping, food preparation, housekeeping, laundry, transportation, medication management, and finances. Scores range from 0 to 8 with higher scores indicating better functioning.
- Employment status as characterized by the Outcomes After Critical Illness and Surgery (OACIS) Employment Status Questionnaire [6-months]
9-item survey that characterizes the patient's baseline (prior to the critical illness) and current level of employment (full, partial, or not employed). Patients will be categorized as loss of employment or no loss of employment.
- Vital status (dead / alive) [Baseline to hospital discharge, approximately 5 days]
Death during the index hospitalization will be recorded.
- Vital status (dead / alive) [6-months]
Death within 6-months will be recorded.
- Intensive care unit admission (yes/no) [Baseline to hospital discharge, approximately 5 days]
Intensive care unit admission at any point during the index hospitalization will be recorded.
- Mechanical ventilation (yes/no) [Baseline to hospital discharge, approximately 5 days]
Invasive mechanical ventilation is defined as new assisted positive pressure breathing through an endotracheal tube or tracheostomy for any duration. Noninvasive ventilation through a mask or nasal prongs does not satisfy the outcome of invasive mechanical ventilation.
- Vasopressor use (yes/no) [Baseline to hospital discharge, approximately 5 days]
defined as the administration of any of the following medications by continuous infusion for at least 1 hour during the index hospitalization: norepinephrine, epinephrine, dopamine, phenylephrine or vasopressin.
- Pleural drainage (yes/no) [Baseline to hospital discharge, approximately 5 days]
Pleural drainage is defined as removal of fluid from the pleural space by any procedure at the bedside or in the operating room during the index hospitalization; procedures such as thoracentesis and video-assisted thorascopic surgery (VATS) may be used to drain pleural fluid.
- Hospital length of stay in (days) [Baseline to hospital discharge, approximately 5 days]
Duration of hospitalization (presentation to hospital discharge) will be recorded.
