Interstitial lung disease (ILD) refers to a group of conditions affecting the lungs. The conditions in this group affect the interstitium, which is a network of tissue that exists in the lungs. The function of the interstitium is to support the alveoli in the lungs and assist with the gas exchange between blood and air in the lungs. Progression of the disease leads to fibrosis (scarring) of the lung. This is an irreversible condition which leads to an accelerated decline in lung function.
Interstitial lung disease can be caused by chronic exposure to harmful materials, such as asbestos. Certain autoimmune diseases, such as rheumatoid arthritis, can affect the lungs and lead to interstitial lung disease. Certain drugs may also cause the disease. In some cases, however, the causes remain unknown. These are referred to as idiopathic interstitial pneumonia (IIP), with idiopathic pulmonary fibrosis (IPF) being the most common and severe type.
Imaging of the lungs is done through X-rays, but more accurately, CT scans lead to the diagnosis. If there is no obvious cause, a biopsy of the lung may be necessary to guide further treatment. Prevalent signs include shortness of breath, a persistent dry cough, and unexplained weight loss.
Treatment of the underlying disease or withdrawal of offending drugs and toxins is crucial to preventing progression and improving symptoms. There are new drugs on the market to treat the idiopathic form of the disease (IPF), but these drugs do not cure the disease and are prohibitively expensive.
These drugs include corticosteroids and other medications like methotrexate or azathioprine, which can reduce inflammation and suppress the immune system. Ultimately, the prognosis depends on the response of the ILD to corticosteroid (cortisone) treatment. Supplemental oxygen can help alleviate symptoms and enhance oxygen levels in the blood, making it easier to breathe, especially during physical activity and sleep.
Lung transplantation may be necessary for patients with serious ILD who do not respond to other treatments and have significant impairment in lung function. It is a complex procedure that necessitates careful evaluation and long-term follow-up.
Support can be sought through healthcare providers, patient support groups, and organisations dedicated to lung health. Connecting with others who have ILD can provide emotional support and practical advice for managing the disorder.
Smoking can contribute to the development of some forms of ILD, particularly by worsening lung function and exacerbating symptoms. Quitting smoking is crucial for managing the disease.
