What is Desquamative interstitial pneumonia?

Desquamative interstitial pneumonia is chronic lung inflammation characterized by mononuclear cell infiltration of the airspaces; it occurs almost exclusively in current or former cigarette smokers. Desquamative interstitial pneumonia is a type of idiopathic interstitial pneumonia.

What is Bronchiolocentric interstitial pneumonia?

Bronchiolocentric interstitial pneumonia is a bronchiolocentric process associated with centrilobular and peribronchiolar fibrosis and a patchy distal lymphocytic alveolitis lacking the presence of interstitial granulomas.

What is fibrosing interstitial pneumonia?

Fibrosing pneumonias are a group of interstitial lung diseases with a different etiologic background and divergent prognosis. They are differentiated into usual interstitial pneumonia (UIP), non-specific interstitial pneumonia (NSIP), and organizing pneumonia (OP).

What is usual interstitial pneumonia?

Usual interstitial pneumonia (UIP) refers to a morphologic entity defined by a combination of (1) patchy interstitial fibrosis with alternating areas of normal lung, (2) temporal heterogeneity of fibrosis characterized by scattered fibroblastic foci in the background of dense acellular collagen, and (3) architectural …

What is Lambertosis?

Lambertosis is associated with tobacco use and may be a reactive process due to chronic injury to terminal and respiratory bronchioles. The metaplasia is presumed postinflammatory in origin and may be a consequence of bronchiolitis, chronic hypersensitivity pneumonitis, bronchiectasis, or COPD.

What is Peribronchiolar metaplasia?

Peribronchiolar metaplasia is a histologic lesion characterized by fibrosis and bronchiolar epithelial proliferation in the peribronchiolar alveolar septa, extending to the terminal bronchioles through the canals of Lambert.

How is interstitial pneumonia treated?

Most patients with the cellular type of nonspecific interstitial pneumonia respond well to treatment with oral corticosteroids, such as prednisone. However, patients who do not respond to corticosteroid therapy may require additional treatment with immune-suppressing drugs.

What kind of lung disease is usual interstitial pneumonia?

Usual interstitial pneumonia ( UIP) is a histopathologic and radiologic pattern of interstitial lung disease, which is the hallmark pattern for idiopathic pulmonary fibrosis (IPF) .

Why do I have a persistent pulmonary infiltrate?

This is the case for pneumonia, but persistent pulmonary infiltrates may result from other reasons (e.g., pulmonary edema). Resolution of nonresolving pneumonias varies and depends on the causal agent, the severity of disease, and host factors.

What to do if you have bilateral interstitial pneumonia?

But anti-fibrotic drugs like nintedanib ( Ofev) and pirfenidone ( Esbriet) help keep the scarring from getting worse. Other treatments include oxygen therapy and pulmonary rehab, which includes breathing exercises to improve your lung strength. If nothing else works for you, you might need a lung transplant.

How does the interstitial lung disease ( ILD ) work?

Interstitial lung disease (ILD) is an umbrella term used for a large group of diseases that cause scarring (fibrosis) of the lungs. The scarring causes stiffness in the lungs which makes it difficult to breathe and get oxygen to the bloodstream. Lung damage from ILDs is often irreversible and gets worse over time.
