"Does 10 days of antibiotics work as well as 14? Help us determine what is the optimal treatment for patients with CF pulmonary exacerbation"
18 to 100 years old
Healthy Volunteers:
cystic fibrosis, pulmonary exacerbation
Drug study, Phase 4
This study wants to answer questions about patients with cystic fibrosis (CF) who have a pulmonary exacerbation and will be treated with antibiotics given through a tube inserted into a vein (intravenously or IV). A pulmonary exacerbation is a worsening of respiratory symptoms and usually involves the use of antibiotics given either in the hospital or at home. Both doctors and CF patients have questions about the best way to treat pulmonary exacerbations. Doctors and CF patients want to make sure the patient gets antibiotics long enough to get better but don’t treat too long and expose the patient to unnecessary risks. This study is trying to answer the following questions about treating a pulmonary exacerbation:
• How long do you need to take antibiotics for a pulmonary exacerbation?
• If patients respond well to the initial antibiotic treatment, does a shorter length of treatment (10 days) with antibiotics work as well as 14 days?
• If patients don’t respond well to the initial antibiotic treatment, does a longer length of treatment (21 days) work better than 14 days?
We will collect sputum to look at the change in bacteria (or germs) during your pulmonary exacerbation. In addition, this research study collects blood and sputum to be stored for future research; this is called specimen banking. The research study will also collect some information about the costs associated with a pulmonary exacerbation for future study.
This study requires

History and physical Blood draws Spirometry: This test measures how much air your lungs can hold and how fast you can breathe out. You will take a deep breath and then blow into a mouthpiece as hard as you can and for as long as you can. You might have to wear soft nose clips during the test to stop air from escaping through your nose. Questionnaires Expectorated Sputum: Sputum is mucus from your lungs. If you are able to, we will ask you to breathe in deeply and cough hard several times to bring up sputum from deep in your chest. The samples will be collected to grow the bacteria that are present in the sputum. Any sample left over will be stored for future research (banking). Antibiotic treatment (given at hospital or home)

Exclusion Criteria:

Key Exclusion Criteria
