Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention in this study is the administration of intravenous dexamethasone (a type of steroid) 4mg twice daily for two days (4 doses total). The drug will be administered by registered nurses.

Arm 1: 2/3 (53 people) will receive the study drug.
Arm 2: 1/3 (27 people) will receive a placebo. A placebo is a medication that looks like the study medication (dexamethasone) but doesn't contain any active drug.

The study drug will be mixed with sterile normal saline and administered as an infusion over 15 minutes.
Intervention code [1] 301117 0
Treatment: Drugs
Comparator / control treatment
The control treatment (placebo) will be intravenous sterile normal saline administered twice daily for two days (4 doses total). Normal saline is a type of fluid that is often administered to patients who are unwell or fasting for any reason. The solution will be made up to look like the active medication. There are no known harmful effects from receiving small volumes of normal saline intravenously.

Placebo

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The NHMRC Clinical Trials Centre will manage randomization through an automated telephone based interactive voice response service (IVRS) that is available 24 hours a day. Automatic randomisation following the entry of baseline and minimisation data will be confirmed by emails sent to the enrolling site and the lead site. The system will also generate the individual participant unique identity number (UIN). The lead site will regularly check randomisation arm parity.
The randomisation will be performed by the research team over the phone. A randomisation number will be allocated and added to the prescription form that is sent to pharmacy.
Only the site pharmacy will be contacted by email by the randomisation service to inform them as to whether the participant has been randomised to the treatment or the placebo arm (unblinded email).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Dynamic (adaptive) random allocation methods using minimisation for three variables:
1. A history of diabetes, aiming to have the risk of hyperglycaemia the same in each arm.
2. Chalmers' score, which is a prediction score for development of complicated parapneumonic effusion and will ensure the severity of the illness is even in each arm.
3. Size of pleural effusion on the chest x-ray.

Statistical methods / analysis
As this is a pilot study, no data exists to determine the sample size. We aim to recruit a total of 80 participants from the participating sites. This will allow inclusion of the full range of parapneumonic effusions at various stages. The 2:1 randomization strategy will include 50+ patients into the dexamethasone arm to increase the power of detecting treatment related adverse events. The results of this pilot study will inform the power calculation of future studies.
Data will be analysed on an intention-to-treat basis. As a general principle, intergroup comparison will be conducted using Student’s t test or Mann-Whitney rank sum test (for parametric and non-parametric distributions respectively). Changes in parameters before and after treatment within the same subject will be analysed using a paired t test or Wilcoxon signed rank test. Correlations will be analysed using Pearson’s or Spearman’s tests. Multivariate analyses may be performed if indicated.

Summary
Brief summary
The lung and the inside of the chest wall are both covered by a thin lining called the pleura, which produces a very small amount of fluid to lubricate the lung during normal breathing. Pneumonia can cause a build-up of fluid in between the pleural linings called a parapneumonic pleural effusion. In many cases, the effusion clears up with antibiotics; less commonly, a chest tube is required to drain the fluid.
Steroids are anti-inflammatory medications that have been used for many years in the management of many medical conditions such as rheumatoid arthritis and asthma. In certain serious infections, inflammation is thought to be the cause of some of the symptoms, and steroids have been used to reduce these effects. Steroids have been used in people with pneumonia in the past with some success, and importantly, few side effects.

There is some evidence to suggest that parapneumonic pleural effusions occur because of excessive inflammation, which may delay recovery. A recent study in children showed that patients with a parapneumonic effusion recovered faster if they were treated with steroids in addition to antibiotics. In this study, we aim to assess whether administering steroids to adults with a parapneumonic effusion will speed up their recovery from the illness.

Study participants will receive 4 doses of steroid or a placebo over 48 hours. A placebo is a medication that looks the same as the steroid but doesn't contain any active drug. This study will be "double-blind" which means that neither the participant, nor the doctor, will know which treatment is administered until the end of the study. It is a randomised clinical trial which means that each participant will be put in one of the study groups (to receive the active drug or placebo) by chance and will not be able to choose their treatment. Two-thirds of participants will receive the study drug and one third will receive placebo.

The 48 hour treatment course is considered to be short, which means that there is much less likelihood of any side effects. The main side effect of steroids is high glucose levels in the blood, which typically go back to normal once the treatment is stopped. Other possible side effects include inflammation/bleeding in the stomach, suppression of the immune system and worsening infection, oral thrush and mood disturbance. In studies that have been done so far, none of these were more common in the group treated with steroids compared to those who weren’t.

The outcomes that we will assess to compare the two groups will include the time to recovery from the illness, changes in blood tests and chest x-rays over time, duration of antibiotic therapy and length of stay in hospital, need for a procedure to drain the fluid, quality of life over the 30 days post-treatment, adverse events (side effects of treatments) and overall survival. The data collected will be analysed by a statistician.
