However, the potential for massive inhalation with the use of vaping devices could account for the more acute presentations of the current cases.[reliasmedia.com]
The subacute form is characterized by the insidious onset of productive cough, dyspnea, and fatigue over weeks to months. Chronic hypersensitivity pneumonitis is characterized by long-term progressive dyspnea, weight loss, cough, and fatigue.[amboss.com]

Other symptoms include wheezing, fatigue, decreased pulse oximetry, and chest pain. Time to onset after initiation of therapy varies (reported at 9 days to 19 months), but the median is 2.8 months.[voice.ons.org]
Radiation pneumonitis generally occurs within 6 months of completing irradiation treatment [ 15 ], subsiding spontaneously or after steroid therapy, resulting in a fibrous lesion with collapse.[futuremedicine.com]

For the patient with nonspecific symptoms, such as cough, dyspnea, fatigue, and hypoxia, the following factors can raise flags for certain conditions: Hypercarbia: immune checkpoint inhibitor–associated myasthenia gravis Superventricular tachycardia,[ascopost.com]
Two weeks later, she came to the emergency department once again due to sudden dyspnea when climbing stairs associated with a feeling of retrosternal oppression that increased with deep breathing and palpitations.[archbronconeumol.org]
Grade it per the Common Terminology Criteria for Adverse Events and direct further workup and management by the toxicity grade. For grade 2 or higher, perform a nasal swab and sputum and urine culture and sensitivity as part of an infectious workup.[voice.ons.org]
Workup Recommendations Workup of patients with suspected pneumonitis includes sputum cultures and nasopharyngeal swabs. It is especially important to look for evidence of viral infection in the winter months.[ascopost.com]
Blood workup revealed normal ionogram, C-reactive protein 80 g/dl, leukocytes 11 430 mm 3 (90% neutrophils and 1.4% eosinophils), hemoglobin 12.4 g/dl, hematocrits 36.4%, platelets 309 000 mm 3.[archbronconeumol.org]

Discuss treatment options with your healthcare providers to decide what care you want to receive. You always have the right to refuse treatment. The above information is an educational aid only.[drugs.com]
Steroid therapy is helpful for symptomatic relief, but probably does not affect the long-term prognosis.[mayoclinic.pure.elsevier.com]
PrognosisPrognosis is good with early diagnosis and management. Late-diagnosed chronic pneumonitis may lead to progressive, irreversible lung disease.[patient.info]
However, when smokers do develop hypersensitivity pneumonitis, it is more commonly fibrosing disease with a worse prognosis 10.[radiopaedia.org]
Centrilobular accentuation of peribronchiolar fibrosis is very suggestive of hypersensitivity pneumonitis Surrounds and may occlude bronchiole Fibrosis may bridge from centrilobular to peripheral zones Fibrosis is generally not reversible and imparts a poor prognosis[surgpathcriteria.stanford.edu]
The prognosis for the acute form is good. Once severe damage to lung structures has occurred, however, few treatment options remain. Chronic hypersensitivity pneumonitis may lead to pulmonary fibrosis, which may ultimately require transplantation.[amboss.com]
They received empiric antibiotics recommended for treatment of community-acquired pneumonia, but tests for microbiological etiologies proved negative.[reliasmedia.com]
One is confronted with the same difficulty in placing the pneumonias, though some progress is being made toward adoption of an etiological classification.[annals.org]

Details of the pathophysiology of this disease are still unknown, but for drugs with a high volume of distribution, one possibility would be specific accumulation of the mTOR inhibitor or its metabolites in the lung parenchyma.[revistanefrologia.com]
Despite the frequency with which both radiation- and ICB- related pneumonitis occur, the pathophysiology remains unclear, and there is little data to suggest which clinical risk factors might be the most relevant.[jitc.biomedcentral.com]
The precise pathophysiology of the differences between PD1/PDL-1 inhibitors and CTL-4 inhibitors is yet to be uncovered.[frontiersin.org]
Oxygen therapy to prevent a low level of oxygen in the body. Bronchodilators may be given to help open up the lungs for better oxygenation. Steroids may be given to lessen inflammation and help the lungs heal. If you smoke, stop.[oncolink.org]
The chronic form of this condition can be prevented by avoiding the material that causes the lung inflammation.[uihc.org]
The chronic form can be prevented by avoiding the material that causes the lung inflammation.[medlineplus.gov]
The inflammation can make it hard to breathe and prevent you from getting enough oxygen. Anything that irritates your lung tissues can lead to pneumonitis. The longer you are exposed, the more damage your lungs will develop.[drugs.com]
Prevention Avoiding exposure to dust or chemicals is important. If a person cannot change jobs, he or she should wear a protective masks and work in a well-ventilated place, if possible.[cedars-sinai.edu]
