Asthma in older patients

Asthma morbidity and mortality is highest in patients >65 years old, and underlying airway inflammation in this age group has not been characterized.  In this laboratory, we have studied a model of asthma in aged mice and have investigated whether age alters modulation of airway inflammation.  Presently, the laboratory is translating these studies to evaluate clinical characteristics of asthma in older patients and markers of inflammation in the airways of these patients.  This knowledge will help to direct age-specific anti-inflammatory asthma therapy.

 

Hereditary Angioedema (HAE) 

HAE is a rare disease which affects approximately 4,000 people in the US.  Its symptoms include swelling of the face, airway, extremities and abdomen.  If swelling involves the airways, it can be life-threatening.  Our group has been involved in several clinical trials for new medications to treat HAE.  In addition, the laboratory is presently studying mechanisms by whichestrogen can exacerbate HAE.
