Use of complementary and alternative medicine by food-allergic patients

Interest in complementary and alternative medicine (CAM) is increasing. Use of CAM in food-allergic patients has not previously been evaluated.

To determine the prevalence of CAM use, the types of CAM modalities used, and opinions about CAM in food-allergic patients.

A questionnaire was distributed to attendees at a patient conference in 2002 and to patients at pediatric food allergy clinics in 2005.

Surveys were completed by 380 families. Respondents were mainly white, parents of children with multiple food allergies, and from the tri-state (New York, New Jersey, Connecticut) area. Diagnostic modalities considered unproven or disproven (such as serum IgG4, electrodermal skin testing, and kinesiology) were used by 22% of respondents; CAM therapies were used by 18%. Participants used several types of CAM practitioners, the most common being chiropractors, homeopaths, and acupuncturists. Only 49% of patients using CAM disclosed this to their physicians. Efficacy ratings for CAM were poor. Regarding participants' opinions, an herbal therapy of equal efficacy, safety, and cost was preferred to a pharmaceutical drug (37% vs 12%; P = .001), but most participants (51%) had no preference or were unsure.

Unproven or disproven diagnostic methods and CAM treatments were used by approximately 1 in 5 respondents. Those using CAM noted poor efficacy, but if given a choice, many would prefer herbal therapies to pharmaceutical drugs. Education regarding reliable testing for food allergy and further research on CAM therapies are warranted.
