Doctor’s response. Polymyositis is characterized by inflammation of muscle. It can, however, be associated with lung disease. There are a variety of lung abnormalities that can occur in patients with polymyositis. These include scarring of the lung tissue (referred to as pulmonary fibrosis or interstitial lung disease ),…
What are the complications of pulmonary fibrosis?
Complications of pulmonary fibrosis may include: 1 High blood pressure in your lungs (pulmonary hypertension). 2 Right-sided heart failure (cor pulmonale). 3 Respiratory failure. This is often the last stage of chronic lung disease. 4 Lung cancer. Long-standing pulmonary fibrosis also increases your risk of developing lung cancer.
What percentage of myositis patients have lung disease?
Researchers estimate that 30-40% of myositis patients have some form of lung disease. There is also a strong association between interstitial lung disease and antisynthetase antibodies. Of those patients who have interstitial lung disease, about 75% have anti-Jo-1 antibodies.
What is the frequency of polymyositis?
Polymyositis (PM) and dermatomyositis (DM) are systemic inflammatory disorders that may be associated with diffuse interstitial lung disease (ILD). The frequency of ILD in PM–DM has been reported to range between 5 and 30% depending on the diagnostic method (1, 2).
Why does pulmonary fibrosis cause scarring?
This thickened, stiff tissue makes it more difficult for your lungs to work properly. As pulmonary fibrosis worsens, you become progressively more short of breath. The scarring associated with pulmonary fibrosis can be caused by a multitude of factors.
What are the final stages of pulmonary fibrosis?
Pulmonary fibrosis is, unfortunately, incurable. However, the disease is treatable. Stage four pulmonary fibrosis is often referred to as end-stage pulmonary fibrosis, which is the final stage of the disease, but stage four pulmonary fibrosis treatment is possible despite its severity.
What are the first signs of pulmonary fibrosis?
Signs and symptoms of pulmonary fibrosis may include: Shortness of breath (dyspnea) A dry cough. Fatigue. Unexplained weight loss. Aching muscles and joints.
What are the end life symptoms of pulmonary fibrosis?
The end stage of pulmonary fibrosis refers to respiratory failure. In the stage, the disease becomes extremely severe. The most common end life symptoms of pulmonary fibrosis include: Severe shortness of breath. Can’t maintain normal oxygen levels. Blue tinges on the skin and mucus membranes.
What happens during the final stages of pulmonary fibrosis?
While disease progression varies, there are some common end stage or final stage pulmonary fibrosis symptoms. For example, some people have reduced lung function. Low blood oxygen levels caused by reduced lung function can make the body retain fluids. Typically, fluid retention occurs in the legs and abdominal areas.
