Steroid resistant asthma

Asthma is usually a steroid responsive disease. A few patients respond poorly to these drugs, and others need such high doses to control the disease that side-effects become a serious problem. The term steroid resistant asthma is used for both groups. In some patients, factors may be operating to make the asthma worse and, thus, to increase the requirement for steroids.

Occupational Asthma

Occupational asthma is a lung disorder in which substances found in the workplace cause the airways of the lungs to swell and narrow, leading to attacks of wheezing, shortness of breath, chest tightness, and coughing.

Many substances in the workplace can cause occupational asthma. The most common triggers are wood dust, grain dust, animal dander, fungi, or other chemicals (especially diisocyanates).
Though the actual rate of occurrence of occupational asthma is unknown, it is suspected to cause 2 - 20% of all asthma cases in industrialized nations.
The following workers are at higher risk:
  • Bakers
  • Detergent manufacturers
  • Drug manufacturers
  • Farmers
  • Grain elevator workers
  • Laboratory workers
  • Metal workers

Exercise-Induced Asthma

Even exercise can induce an asthma attack in people who have no other triggers and do not experience asthma under any other circumstances.People with exercise-induced asthma are believed to be more sensitive to changes in the temperature and humidity of the air.When you are at rest, you breathe through your nose, which serves to warm, humidify, and cleanse the air you inhale to make it more like the air in the lungs.
When you are exercising, you breathe through your mouth, and the air that hits your lungs is colder and drier. The contrast between the warm air in the lungs and the cold inhaled air or the dry inhaled air and moist air in the lungs, can trigger an attack.
