Prevalence and Impact on Quality of Life of Airway Disease in Patients With Idiopathic Pulmonary Fibrosis

July 9, 2017 updated by: Sun Mi Choi, Seoul National University Hospital
The investigators assess the prevalence of airway disease associated with idiopathic pulmonary fibrosis in Korea, and evaluate the effect of these airway diseases on the symptoms and quality of life of patients with idiopathic pulmonary fibrosis.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Idiopathic pulmonary fibrosis (IPF) is defined as a specific form of chronic, progressive fibrosing interstitial pneumonia of unknown cause, occurring primarily in older adults, and limited to the lungs. It is characterized by progressive worsening of dyspnea and lung function and is associated with a poor prognosis.

The main symptoms of patients with IPF are dyspnea on exertion and a persistent dry cough or mildly productive cough.

In many IPF patients, cough is often the first symptom, preceding dyspnea on exertion sometimes by years. It affects upwards of 70-85% of patients with IPF.

Chronic obstructive pulmonary disease (prevalence rate 4-18%) and asthma (prevalence rate 5.9-9.9%) are the airway disease whose main symptoms are also dyspnea and cough.

To date, the effect of airway disease has not been well studied in patients with idiopathic pulmonary fibrosis, and the prevalence is unknown in Korea.

Unlike idiopathic pulmonary fibrosis, airway disease is a treatable, modifiable disease, so treatment of these diseases may improve QOL in IPF patients.

Therefore, this study's purpose is A. Identify the prevalence of airway disease in IPF patients B. Identify differences in QOL and symptoms according to presence of airway disease C. Identify the symptomatic improvement after active treatment for the airway diseases

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of participants who have asthma combined with idiopathic pulmonary fibrosis
Time Frame: Through study completion, an average of 2 year
Confirmation of asthma : pulmonary function test with bronchodilator response or Methacholine provocation test
Through study completion, an average of 2 year
Number of participants who have COPD combined with idiopathic pulmonary fibrosis
Time Frame: Through study completion, an average of 2 year
Confirmation of COPD : pulmonary function test with bronchodilator response
Through study completion, an average of 2 year
Number of participants who have Eosinophilic bronchitis combined with idiopathic pulmonary fibrosis
Time Frame: Through study completion, an average of 2 year
Confirmation of Eosinophilic bronchitis : pulmonary function test with bronchodilator response, induced sputum

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
