- Cushing disease
- Had an organ transplant

- Gastrointestinal system
- Lungs and airways
- Muscles and joints
- Nervous system
Signs and tests
The goal of treatment is to control the infection. Antibiotics are used, but it may take a while to get better. You must keep taking the medications for at least 3 months.
Surgery may be needed to remove or drain infected areas.
Your health care provider may tell you to stop taking any medicines that weaken your immune system. Never stop taking any medicine before talking to your health provider first.
The outcome is often good when diagnosed and treated quickly.,
The outcome is poor when the infection spreads outside the lung, treatment is delayed, or the patient has serious underlying diseases.
Calling your health care provider

Be careful when using corticosteroids. Use these drugs sparingly, in the lowest effective doses and for the shortest periods of time possible.
Some patients with an impaired immune system may need to take antibiotics for long periods of time to prevent the infection from returning.
