Study on the Impact of Decolonization Treatment of Pneumocystis Jirovecii on the Frequency of Acute Exacerbation in COPD
A Multicenter, Prospective, Double-blind, Randomized Controlled Study on the Impact of Decolonization Treatment on the Frequency of Acute Exacerbation in Patients With Chronic Obstructive Pulmonary Disease Colonized With Pneumocystis Jirovecii
Previous researches have found the common colonization of Pneumocystis jirovecii (Pj) in the airways of people with chronic obstructive pulmonary disease (COPD). And this colonization may exacerbate airway inflammation and increase the frequency of acute exacerbation in people with COPD.
The goal of this clinical trial is to study if "decolonization treatment" (that is, removing these colonizing Pj) works to improve the prognosis of COPD colonized by Pj in adults. The main question it aims to answer is:
- Does the Trimethoprim-Sulfamethoxazole (TMP-SMX, an antibiotics) decolonization treatment reduce the frequency of acute exacerbation in participants with COPD colonized by Pj who have a high risk of acute exacerbation.
Researchers will compare TMP-SMX to a placebo (a look-alike substance that contains no drug) to see if TMP-SMX works to reduce the frequency of acute exacerbation of COPD.
Participants will:
- Take drug TMP-SMX or a placebo 2 tablet every day for 4 weeks.
- Visit the clinic after 2 weeks, 1 month, 3 months, 6 months and 12 months for survey questions, checkups and tests.
- Keep a diary of their symptoms and the number of times they experience acute exacerbations
