"Ask the Allergist" questions are answered by Dr. Douglas Johnston, an Allergist/ Immunologist with Asthma & Allergy Specialists, P.A. in Charlotte, NC.

College: Fairfield University
Medical School: New York College of Osteopathic Medicine
Internship and Residency: Winthrop University Hospital, Mineola, NY
Fellowship: University of Alabama at Birmingham
Board Certified in Internal Medicine, Allergy and Immunology.

In college, Dr. Johnston was drawn to Immunology and considered a career as an immunologist. After spending time working in the lab, he realized that it would be much more exciting to treat people with immune disorders and allergy, especially since he grew up having both allergies and asthma. Dr. Johnston was attracted to Osteopathic medicine because its core principles focus on the body's ability to function as a whole and heal itself, a key role of the immune system.

Aside from allergies and asthma, Dr. Johnston has an interest in hereditary angioedema (HAE), a rare genetic swelling disorder. He has published several articles on this topic and has had the opportunity to educate physicians on HAE both in the US and internationally.

He is very passionate about food allergy which stems from having a child with peanut allergy. In addition, Dr. Johnston has had the opportunity to treat a large number of patients with Eosinophilic Esophagitis (EoE) and has recently published an abstract demonstrating that diets guided by skin prick and atopy patch tests are a successful approach to treating many patients with EoE. He had the pleasure of speaking at the 2011 APFED national patient conference.

Dr. Johnston is a fellow of the ACAAI, AAAAI and a member of the Clinical Immunology Society. He is an Associate Professor of Internal Medicine/ Allergy & Immunology at the Edward Via School of Osteopathic Medicine in Spartanburg, SC. He is on the editorial board of the Journal of Allergy and Therapy. Dr. Johnston is also a member of the AAAAI In-Training Exam Committee and the AAAAI Allergic Skin Disease Committee.

When not working, he enjoys traveling with his family and cooking.
