New Research Uncovers Why Many With Lupus Are Resistant to Traditional Treatments
Findings Could Lead to Lower Doses of Medication for Lupus Patients, Reducing Serious Side Effects
Tuesday, July 13, 2010
/PRNewswire/ -- Two immune system proteins could be the culprit behind many lupus patients' resistance to widely used steroid treatments, scientists with the Baylor Research Institute (BRI) in Dallas announced today. It is estimated that more than 5 million people suffer from lupus worldwide.
Currently, those with lupus and other autoimmune diseases, commonly treat the condition with corticosteroids to suppress their overactive immune system and prevent it from attacking healthy tissues which can result in symptoms such as inflammation, pain and organ damage.
These steroid treatments work by killing certain immune system cells, including plasmacytoid dendritic cells (PDCs) that overproduce type 1 interferons, an immune system substance that contributes to lupus and other autoimmune diseases. However, unlike other conditions, steroid treatments are not as effective against these cells in those with lupus.
