Abstract

A population of difficult-to-control asthmatics exists who, despite high-dose daily GC therapy, continue to display evidence for active disease. This group has been termed steroid resistant since they fail to adequately respond to aggressive courses of high-dose oral and inhaled GC therapy. Persistent immune activation and airway inflammation which to varying degrees is resistant to GC therapy appears to define the immunological abnormality underlying SR asthma. Recent studies utilizing molecular biological techniques have identified both ligand- and DNA-binding defects that could possibly account for steroid resistance at a molecular level. The evaluation of the SR asthmatic must be comprehensive in its scope as several confounding factors can contribute to this symptom complex. Among others, these include poor compliance, improper medication technique, inadequate anti-inflammatory therapy, unrecognized contributing diseases, incorrect diagnoses, environmental factors, and psychosocial disturbances. The management of the SR asthmatic is challenging, and every attempt should be made to maximize conventional therapy in these patients prior to embarking on alternative therapies as all of the alternative anti-inflammatory/immunomo...Continue Reading

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
