What is the most common drug-induced respiratory problem?
What is the most common drug-induced respiratory problem?
Interstitial pneumonitis (ie, inflammation of the lung interstitium, such as the alveolar septa) is the most common manifestation of drug-induced lung disease. A wide array of drugs can cause interstitial pneumonitis.
How is hypersensitivity lung disease diagnosed?
Diagnosis and Tests Your doctor diagnoses HP by taking a detailed personal history and performing a physical examination. During your examination, your doctor listens to your lungs with a special instrument called a stethoscope. If you have HP, your doctor may hear abnormal crackles, pops, or other lung sounds.
What is hypersensitive pneumonia?
Hypersensitivity pneumonitis is an immune system disorder in which your lungs become inflamed as an allergic reaction to inhaled microorganisms, plant and animal proteins or chemicals.
What is hypersensitivity pneumonitis caused by?
Hypersensitivity pneumonitis is caused when you breathe in a specific substance (allergen) that triggers an allergic reaction in your body. These allergens are often naturally occurring—such as bird feathers or droppings, household mold and animal dander.
What causes wheezing sound in asthma?
Asthma is a chronic condition that causes spasms and swelling in the bronchial tubes. Wheezing in asthma can be triggered by exposure to airborne allergens such as pollen, mold, animals, or house dust. Viral illnesses can also make asthma symptoms worse. Bronchitis is inflammation of the lining of the bronchial tubes.
What meds cause shortness of breath?
Medications that can precipitate respiratory impairment include ACE inhibitors, NSAIDs, anticonvulsants, beta blockers, calcium channel blockers, cholinergics, antihypertensives, antibiotics, antifungals, antimicrobials, antiretrovirals, digoxin, interferon, and chemotherapy agents.
What type of hypersensitivity is asthma?
It is a type I hypersensitivity reaction, that is an immediate exaggerated or harmful immune reaction. Interestingly, only 7% of allergic people develop asthma,43 which can lead us to believe that they present a unique phenotype that distinguishes them from other allergic, but nonasthmatic, individuals.
Can you recover from hypersensitivity pneumonitis?
After an acute episode of hypersensitivity pneumonitis, a person can usually recover without treatment if he or she has no more contact with the allergen. In serious cases, it may be necessary to use corticosteroids, such as prednisone, to lessen the symptoms and reduce inflammation in the lungs.
How do I know if I have hypersensitivity pneumonitis?
Common symptoms include fever, chills, muscle aches, headache and cough. These symptoms may last for as little as 12 hours to a few days and will resolve if further exposure is avoided. Chronic hypersensitivity pneumonitis develops after numerous or continuous exposures to small amounts of the allergen.
Is hypersensitivity pneumonitis serious?
Hypersensitivity pneumonitis may cause the following potentially fatal complications if the condition is not diagnosed or well controlled by treatment. Irreversible lung damage and permanently reduced lung function because of severe fibrosis and impaired ability to oxygenate the blood during normal breathing.
Is asthma wheeze on inhale or exhale?
Expiratory wheezing alone often indicates a mild airway obstruction. Inspiratory wheezing occurs when you inhale. In some people with asthma, you can only hear wheezing during the inspiratory phase. If you’re wheezing when you exhale and inhale, you could have a more severe breathing issue.
What is status asthmaticus in medical practice?
Practice Essentials. Status asthmaticus is considered a medical emergency. It is the extreme form of an asthma exacerbation that can result in hypoxemia, hypercarbia, and secondary respiratory failure. In practice, the role of the physician is to prevent this from happening through patient compliance with controller medications (eg,…
What is the pathophysiology of asthma?
Asthma is a common chronic disease worldwide and affects approximately 26 million persons in the United States. It is the most common chronic disease in childhood, affecting an estimated 7 million children. The pathophysiology of asthma is complex and involves airway inflammation, intermittent airflow obstruction, and bronchial hyperresponsiveness.
What are the signs and symptoms of Status asthmaticus with imminent respiratory arrest?
Findings in status asthmaticus with imminent respiratory arrest include the following: 1 Paradoxical thoracoabdominal movement occurs. 2 Wheezing may be absent (in patients with the most severe airway obstruction). 3 Severe hypoxemia may manifest as bradycardia. 4 Pulsus paradoxus may disappear: This finding suggests respiratory muscle fatigue.
What is included in medical care for asthmatic disorders?
Medical care includes treatment of acute asthmatic episodes and control of chronic symptoms, including nocturnal and exercise-induced asthmatic symptoms.
