What is ground-glass interstitial disease of the lung?
It is a form of lung disease that looks like ground glass on x-ray and CT scans. The most common causes of ground-glass opacity include usual interstitial pneumonia, nonspecific interstitial pneumonitis, desquamative interstitial pneumonia, hypersensitivity pneumonitis, pulmonary oedema and pulmonary haemorrhage, and pneumonias (particularly pneumocystis carinii pneumonia). Less common causes include alveolar proteinosis, acute interstitial pneumonia or other causes of diffuse alveolar damage or the adult respiratory distress syndrome, respiratory bronchiolitis and early radiation pneumonitis.
Hypersensitivity pneumonitis?
DefinitionHypersensitivity pneumonitis is inflammation of the lungs due to breathing in a foreign substance, usually certain types of dust, fungus, or molds.Alternative NamesExtrinsic allergic alveolitis; Farmer's lung; Mushroom picker's disease; Humidifier or air-conditioner lung; Bird breeder's lungCauses, incidence, and risk factorsHypersensitivity pneumonitis usually occurs in those who work in places where there are high levels of organic dusts, fungus, or molds. For example, farmer's lung is the most common type of hypersensitivity pneumonitis. Repeated or intense exposure to dust from moldy hay, straw, and grain can lead to lung inflammation and acute lung disease. Over time, this acute condition may turn into long-lasting (chronic) lung disease.The condition may also result from fungus present in humidifiers, heating systems, and air conditioners found in homes and offices. Exposure to certain bird droppings (for example, among bird owners) can also lead to hypersensitivity pneumonitis.SymptomsSymptoms of acute hypersensitivity pneumonitis may occur 4 - 6 hours after you have left the area where the foreign substance is found. These symptoms may include:ChillsCoughFeverMalaise(feeling ill)Shortness of breathSymptoms of chronic hypersensitivity pneumonitis may include:Breathlessness, especially with exertionCough, often dryLoss of appetiteUnintentional weight lossSigns and testsYour doctor may hear abnormal lung sounds called crackles (rales) when listening to your chest with a stethoscope.Lung changes due to chronic hypersensitivity pneumonitis may be seen on chest x-ray. Other tests may include:Aspergillus precipitins testBronchoscopy with washings and biopsyCBCHigh-resolution CT scan of the chestHypersensitivity pneumonitis antibody panelsPulmonary function testsVideo-assisted or open-lung biopsyTreatmentFirst, the foreign substance must be identified. Treatment involves avoiding this substance in the future. Some people may need to change jobs if they cannot avoid the substance at work.If you have a chronic form of this disease, your doctor will give you glucocorticoids (powerful anti-inflammatory medicines).Expectations (prognosis)Most symptoms go away when you avoid or limit your exposure to the material that caused the problem.ComplicationsThe chronic form of this disease may lead to pulmonary fibrosis (a scarring of the lung tissue that often is not reversible).Calling your health care providerCall your health care provider if you develop symptoms of hypersensitivity pneumonitis.PreventionThe chronic form can be prevented by avoiding the material that causes the lung inflammation.ReferencesHoppin JA, Umbach DM, Kullman GJ, et al.
