6. Asthma – What is It?  Asthma is a chronic lung- disease that inflames, narrows and obstruct the airways (tubes that bring air into and out of an individual’s lungs).  The obstruction is reversible  It involves difficulty in breathing due to –Inflammation (swelling) –Mucus in the airways –Tightening of muscles around the airways

9. Classification  Clinically(according to severity): 1.Intermittent 2.persistent Mild persistent Moderate persistent Severe persistent  Exercise-induced  Occupational  Aspirin-induced asthma  Alcohol-induced asthma

10. Causes While the exact cause of asthma is not known. Variety of risk factors interacting with one another, early in life, result in the development of asthma e.g. : 1.Parents with asthma 2.Atopy 3.Childhood respiratory infections 4.Exposure to allergens or infections while the immune system is developing

11. What substances trigger asthma? Type of SubstanceExamples Air pollutants, including dusts, smoke, mists & fumes Diesel exhaust; tobacco smoke; mineral, rock, coal, & wood dusts; gases; fumes & vapors from aerosol agents, chemicals, cleaning materials, solvents, paints, welding & from heating & cooling metals quickly Pollens, mites & molds Trees, flowers, weeds, hay, plants Animal dander Birds, cats, dogs Medications Aspirin, anti-inflammatory drugs Foods Egg, wheat, nuts

12. Symptoms of asthma  Coughing  Wheezing, a whistling sound  Shortness of breath  Chest tightness  Sneezing & runny nose  Itchy and inflamed eyes

13. Diagnosis  Based on: –Medical history –Physical examination –Lab tests: 1.Spirometry Spirometry 2.methacholine challengemethacholine challenge 3.CXR 4.CBP & WBC eosinophiles

14. Can asthma be cured?  Asthma can be controlled (but not cured) by: –Avoiding triggers or reducing exposure to triggers –Using medication to control symptoms  Medications - generally two types are used –Controller or long-term drugs Taken to prevent excess production of mucus & to reduce the inflammation and constriction of airway muscles –Rescue or quick-relief drugs Taken to relax muscles around the airways to improve breathing

15. Treatment  Medication –Long term Inhaled corticosteroid Leukotriene modifiers Long-acting beta agonists Combination inhalers

16. Treatment –Quick relief (rescue) medications Short-acting beta agonists Ipratropium Oral and intravenous corticosteroids
