The Effect of Azithromycin in Patients With Chronic Obstructive Pulmonary Disease (COPD) and Chronic Productive Cough

2014-08-27 03:15:49 | BioPortfolio

Summary

The purpose of this study is to demonstrate the efficacy of azithromycin to produce a significant change in the cough-related health status, measured with the Dutch version of the Leicester Cough Questionnaire in patiënts with COPD gold classification 2-4 and chronic productive coughing.

Description

This study is a prospective double-centre, double blind randomised trial. Patients > 40 years of age, referred to our outpatient clinic with chronic cough and sputum production due to COPD will be recruited after informed consent is obtained.

Consenting patients will be randomises to a 12-week treatment with 250 mg azithromycin three times a week or placebo.

Before randomisation all patients have to fill in the SF 36 , SGRQ and the Dutch version of the Leicester Cough Questionnaire (LCQ) for assessment of the baseline quality of life and the disease specific quality of life.

The LCQ questionnaires will be performed at the beginning and every 3 weeks afterwards until 18 weeks, except the second LCQ which will be filled in after 2 weeks. Scores from this questionnaire will be used to calculate the 2-week repeatability. The SF 36 and SGRQ will be performed at the start of the study and after 12 weeks. Adverse events will be recorded during the whole treatment period. After 2 and 12 weeks a Global Rating of Change will be performed. This questionnaire will be used to validate the LCQ in COPD patients.

Randomisation will take place using a computer allocation program (BAMI-computer)

Azithromycin and placebo will be provided by Teva Pharmaceuticals. Placebo and azithromycin will be identical in appearance and packaging.

Medical and Biotech [MESH] Definitions

Agents that suppress cough. They act centrally on the medullary cough center. EXPECTORANTS, also used in the treatment of cough, act locally.

A semi-synthetic macrolide antibiotic structurally related to ERYTHROMYCIN. It has been used in the treatment of Mycobacterium avium intracellulare infections, toxoplasmosis, and cryptosporidiosis.

Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.

An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.

A synthetic opioid that is used as the hydrochloride. It is an opioid analgesic that is primarily a mu-opioid agonist. It has actions and uses similar to those of MORPHINE. It also has a depressant action on the cough center and may be given to control intractable cough associated with terminal lung cancer. Methadone is also used as part of the treatment of dependence on opioid drugs, although prolonged use of methadone itself may result in dependence.
