Dietary Supplement Use in Patients With Celiac Disease in the United States

Dietary Supplement Use in Patients With Celiac Disease in the United States

Journal of Clinical Gastroenterology 49(7): 577-581

There has been increasing interest in the use of complementary and alternative medicine (CAM) in the general population. Little is known about CAM use in patients with celiac disease (CD). We aimed to determine the demographics and clinical characteristics of patients with biopsy-proven CD who use dietary supplements to treat their symptoms. CD patients completed a questionnaire on demographics, types of dietary supplement use, attitudes toward CAM, and 3 validated scales: CD-related Quality Of Life (CD-QOL), the CD Symptoms Index (CSI), and the CD Adherence Test (CDAT). Of 423 patients, 100 (23.6%) used dietary supplements to treat CD symptoms. The most frequently used supplement was probiotics (n=59). Supplement users had a higher CD-QOL score (75.06 vs. 71.43, P=0.04) but had more symptoms based on CSI (35.64 vs. 32.05, P=0.0032). On multivariable analysis, adjusting for age, sex, education, symptom improvement following a gluten-free diet, and where the survey was completed, patients presenting with classic symptoms (OR, 2.56; 95% CI, 1.01-6.44) or nonclassic symptoms (OR, 2.75; 95% CI, 1.04-7.24) were significantly more likely to use supplements than those with asymptomatic/screen-detected CD. Patients with biopsy-proven CD who have symptoms at diagnosis tend to use dietary supplements more than those that are screen detected. Those using supplements report persistent symptoms, but a higher quality of life. The contribution of the gluten-free diet and supplement use to quality of life in the symptomatic CD patient needs to be determined.
