Smoking and Asthma:World Asthma Day

Smoke from cigars, cigarettes, and pipes has adverse effects on almost all the organs of the body in many ways, and even passive smokers are at risk.

Smokers are more likely to get Upper respiratory tract infections, chronic cough and lung conditions and it is a powerful asthma trigger too.

Smoke acts as irritant and causes swelling and narrowing of airway along with excessive mucus thus person may develop cough, wheezing, and shortness of breath.

Smoke induced asthma flare-ups may be more severe and harder to control with medicine as it decreases the effect of the controller medicine.

Quitting smoking can reverse asthma-inducing changes in lungs

ScienceDaily (2009-12-08) — Asthmatic smokers may be able to reverse some of the damage to their lungs that exacerbates asthmatic symptoms just by putting down their cigarettes, according to new research (University of Groningen in the Netherland).

Good evidence supports that smoking cessation lowers the risk  so get convinced to quit smoking…

Quitting smoking is most positive thing you can do for yourself and your loved ones…

And if you need some special day to quit then today is World Asthma day,…

Understanding Asthma: A step towards Asthma Control

World Asthma Day (WAD) is an annual event organized by the Global Initiative for Asthma (GINA) to improve asthma awareness and care around the world.
The theme of World Asthma Day 2010, Tuesday, May 4, 2010 will be “You Can Control Your Asthma.” On WAD, GINA also plans to launch a campaign to reduce asthma hospitalizations by 50% in 5 years.

Patient education plays the pivotal role in control of asthma.

Health care provider should take honest efforts and give proper time in educating every patient regarding–

  • Nature of the disease and causes of inflammation and asthma triggers.
  • Regular monitoring at home by peak flow meter
  • Asthma medication with side effects
  • Technique of using inhaler, spacer and nebulizer
  • Action plan for treating exacerbation
  • Measures to reduce exposure to indoor allergens

Nature of the disease

Asthma is a persistent illness categorized by recurring attacks of breathlessness and wheezing may include coughing and chest tightness, which differ in severity and frequency. Asthma cannot be cured, but it can be controlled with proper management of environment and medication.

Most common cause is inhalation of allergens and bronchial hyper responsiveness to otherwise trivial stimuli. When triggered by stimulus narrowing of airway can occur because of smooth muscle contraction, edema of the wall and increased mucus secretion.

The two main factors that contribute to asthma are inflammation of the airway passages and hyper reactive bronchi**.

Asthma trigger

An asthma attack can occur when you are exposed to things in the environment, these are called asthma triggers.

Asthma triggers can be very different for different person with asthma.  It is important to understand what triggers your symptoms and what makes them go away. You and your health care provider can work together to assure that you avoid exposure to the substance that triggers your asthma symptoms.

Smoker’s are at a greater risk for developing asthma.

Common asthma triggers include:

Irritants

  • dirt, cigarette smoke, secondhand smoke and air pollution
  • household, household cleaners, perfumes, paints, varnishes, fabric softeners, laundry detergents and co-oking fumes
  • in the workplace, fumes and vapors from wood products and metals

Allergen-

  • Dust Mites– dermatophagoids pteronyssinus, d. farina
  • Cockroach – blattella germanica
  • Pets—cat felix domesticus
  • Dog– canis familiaris
  • Rodents mouse/rat  mus muscularis / ratus norweigicus
  • Mold-alternaria alternata, aspergilus fumigatus
  • Pollens—rye grass (lolium perenne, rag weed (ambrosia eletoir, oak

Other Triggers

  • Viral and bacterial upper airway infection such as cold and sinusitis
  • Strong odour and fumes
  • Exposure to cold dry air
  • Strenuous physical exercise;
  • Some medicines Some medications aspirin or other non-steroidal anti-inflammatory drugs (NSAID) such as ibuprofen; and beta-blockers.
  • Bad weather, such as thunderstorms, high humidity, or freezing temperatures;
  • Smoke from burning wood, grass, or other vegetation;
  • Some foods and food additives
  • Strong emotional states
  • Acid reflux

Asthma Treatment

Asthma cannot be cured, but it can be controlled with proper management of environment and medication.

I. Environmental control.

Most important is to avoid environmental trigger factors. Try to find out your triggers and avoid them.

Listed below are some ways–:

Dust mite

  • Vacuum Clean (with   HEPA High Efficiency particulate) the house thoroughly at least once a week.
  • Wear a mask while cleaning the house
  • Avoid pets with fur or feathers
  • Wash the bedding regularly at 130 f / 60 c in hot water
  • Encase the mattress, pillows in dust-proof covers
  • Consider replacing upholstered furniture with leather or vinyl
  • Consider replacing carpeting with hardwood floors or tile
  • Use the air conditioner
  • Keep the humidity in the house low

Cats/dogs

  • Keep animal outside or remove
  • If you cannot avoid exposure, try to minimize contact.
  • Vacuum Clean weekly (With HEPA)
  • Room air filter
  • Wash animal regularly

Cockroaches

  • Block crevices, wall cracks and windows.
  • Keep food in lidded containers
  • Vacuum and sweep the floor after meals, and take out garbage and recyclable.
  • Use lidded garbage containers in the kitchen.
  • Wash dishes immediately after use and clean kitchen surface, under stoves, refrigerators or toasters where crumbs can accumulate.

Indoor Molds

  • Clean up mold growth with water, detergent (and 5% bleach) and dry the area.
  • Wash clothing with soap and water and dry.
  • Seal leaking roofs or pipes.
  • Use dehumidifier in damp areas.

II. Lung function monitoring by peak flow meter

Periodic assessments and ongoing monitoring of asthma are essential to determine if therapy is adequate.

Peak flow meter is a Small device which gives idea of air flow out of your lungs

Patient should be educated regarding use of peak flow meter and symptoms and signs of an asthma exacerbation. Regular follow-up visits are important.

Lung function decreases 3-4 day prior to an asthma attack thus it can help warn of impending exacerbation.

III. Medicines

Since asthma is a chronic disease, it requires ongoing management. This includes using proper medications to prevent and control asthma symptoms.

There are two general classes of asthma medications, quick-relief and long-term controller medications.

Rescue Medications (relievers)-

Quick-relief medications are used to relieve symptoms during acute asthma attack.

It includes Bronchodilators and oral corticosteroids.

Bronchodilator increases the diameter of the air passages thus easing the flow of air to and from the lungs.

The short-acting bronchodilators used to relieve symptoms during acute asthma attack. Eg Metaproterenol , ephedrine, terbutaline and albuterol .

Long-Term Control Medications (Controllers)-

Long-term controller medications are taken on a regular basis to control airway inflammation and treat symptoms in people who have frequent asthma symptoms.

Anti-inflammatory reduces inflammation, and reduce the spontaneous spasm of the airway muscle. Used as a preventive measure to lessen the risk of acute asthma attacks

Inhaled corticosteroids, cromolyn  (need to be taken four times per day) and leukotriene modifiers can help control the inflammation that occurs in the airways of most people who have asthma.

Inhaled long-acting beta agonist are symptom-controllers t hat open your airways and may have other beneficial effects used only along with inhaled corticosteroids.

Theophylline is the most frequently used.

Immunotherapy (allergy shots) may help if avoidance of irritant and medications fail to control asthma. The treatment begins with injections of a solution of allergen given one to five times a week, with the strength gradually increasing.

Patients with persistent asthma should be given an annual influenza vaccine.
