Bronchiolitis obliterans is one type of interstitial lung disease (ILD). This causes inflammation or swelling that leads to scarring of the lungs in the area between the air sacs and the blood vessels. Cigarette smoking does not cause this lung disease. It may be due to toxic fume exposure, lung infection, or connective tissue disease such as arthritis. Most of the time it is not possible to determine exactly what has damaged the lungs. The most common symptoms are an ongoing dry cough and shortness of breath, especially with exercise. This may be why stairs are now presenting a challenge to you. The chest x-ray is usually abnormal. A lung biopsy is done to be certain about the type of ILD. Please read our Interstitial Lung Disease MedFact at http://www.nationaljewish.org/medfacts/interstitial.html for further information. You are welcome to share this information with your doctor.
Steroids like prednisone are frequently the first medicine used. For some people, steroids will help decrease the swelling so it doesn't become scar tissue. This will cause a dramatic improvement. However, some people have only slight improvement with steroids. Steroids need to be started early, before the swelling has become scar tissue. The goal of treatment is that there will be less swelling or at least no further scarring. This is measured by follow up chest x-ray, exercise tests, and pulmonary function tests. It can take at least 3 months of steroids to begin to see improvement. As soon as possible the dose is decreased to avoid steroid side effects. There are many possible side effects from prednisone including muscle weakness. Of the medicines you are taking Zetia can cause muscle weakness and the doxazosin can cause fatigue. However the prednisone is most likely to cause muscle weakness. Please read our Corticosteroid MedFact at http://www.nationaljewish.org/medfacts/corticosteroid.html for further information about the side effects and their prevention. Talk with your doctor about preventing and watching for these side effects.
Pulmonary rehabilitation is a program to bring back your quality of life through aerobic exercise done on a regular basis. When done routinely, this conditions the entire body so that the muscles are working as efficiently as possible. This allows the breathing muscles to use the least amount of energy to move air in and out of the lungs. Over time this helps to lessen muscle weakness and shortness of breath. Some programs will also include education about your lung condition and nutrition. Please read our Pulmonary Rehabilitation MedFact at http://www.nationaljewish.org/medfacts/pulmonary.html for more information. Share this information with your doctor to see if this would be helpful and where in your area there are programs.
Possibly it may be useful to get a 2nd opinion as to your underlying condition and the best possible treatment for it, preferably at a LARGE teaching hospital with a great national reputation, such as National Jewish, Mayo, Johns Hopkins, or similar.
