Dietary Supplement Adverse Event Report Data From the FDA Center for Food Safety and Applied Nutrition Adverse Event Reporting System (CAERS), 2004-2013.

BACKGROUND: The Food and Drug Administration (FDA)'s Center for Food Safety and Applied Nutrition (CFSAN) oversees the safety of the nation's foods, dietary supplements, and cosmetic products. OBJECTIVE: To present a descriptive analysis of the 2004-2013 dietary supplement adverse event report (AER) data from CAERS and evaluate the 2006 Dietary Supplements and Nonprescription Drug Consumer Protection Act as pertaining to dietary supplements adverse events reporting. METHODS: We queried CAERS for data from the 2004-2013 AERs specifying at least 1 suspected dietary supplement product. We extracted the product name(s), the symptom(s) reported, age, sex, and serious adverse event outcomes. We examined time trends for mandatory and voluntary reporting and performed analysis using SAS v9.4 and R v3.3.0 software. RESULTS: Of the total AERs (n = 15 430) received from January 1, 2004, through December 31, 2013, indicating at least 1 suspected dietary supplement product, 66.9% were mandatory, 32.2% were voluntary, and 0.9% were both mandatory and voluntary. Reported serious outcomes included death, life-threatening conditions, hospitalizations, congenital anomalies/birth defects and events requiring interventions to prevent permanent impairments (5.1%). The dietary supplement adverse event reporting rate in the United States was estimated at ~2% based on CAERS data. CONCLUSIONS: This study characterizes CAERS dietary supplement adverse event data for the 2004-2013 period and estimates a reporting rate of 2% for dietary supplement adverse events based on CAERS data. The findings show that the 2006 Dietary Supplements and Nonprescription Drug Consumer Protection Act had a substantial impact on the reporting of adverse events.

Emergency Department Visits for Adverse Events Related to Dietary Supplements.

BACKGROUND: Dietary supplements, such as herbal or complementary nutritional products and micronutrients (vitamins and minerals), are commonly used in the United States, yet national data on adverse effects are limited. METHODS: We used nationally representative surveillance data from 63 emergency departments obtained from 2004 through 2013 to describe visits to U.S. emergency departments because of adverse events related to dietary supplements. RESULTS: On the basis of 3667 cases, we estimated that 23,005 (95% confidence interval [CI], 18,611 to 27,398) emergency department visits per year were attributed to adverse events related to dietary supplements. These visits resulted in an estimated 2154 hospitalizations (95% CI, 1342 to 2967) annually. Such visits frequently involved young adults between the ages of 20 and 34 years (28.0% of visits; 95% CI, 25.1 to 30.8) and unsupervised children (21.2% of visits; 95% CI, 18.4 to 24.0). After the exclusion of unsupervised ingestion of dietary supplements by children, 65.9% (95% CI, 63.2 to 68.5) of emergency department visits for single-supplement-related adverse events involved herbal or complementary nutritional products; 31.8% (95% CI, 29.2 to 34.3) involved micronutrients. Herbal or complementary nutritional products for weight loss (25.5%; 95% CI, 23.1 to 27.9) and increased energy (10.0%; 95% CI, 8.0 to 11.9) were commonly implicated. Weight-loss or energy products caused 71.8% (95% CI, 67.6 to 76.1) of supplement-related adverse events involving palpitations, chest pain, or tachycardia, and 58.0% (95% CI, 52.2 to 63.7) involved persons 20 to 34 years of age. Among adults 65 years of age or older, choking or pill-induced dysphagia or globus caused 37.6% (95% CI, 29.1 to 46.2) of all emergency department visits for supplement-related adverse events; micronutrients were implicated in 83.1% (95% CI, 73.3 to 92.9) of these visits. CONCLUSIONS: An estimated 23,000 emergency department visits in the United States every year are attributed to adverse events related to dietary supplements. Such visits commonly involve cardiovascular manifestations from weight-loss or energy products among young adults and swallowing problems, often associated with micronutrients, among older adults.

Characterization of Listeria monocytogenes recovered from imported cheese contributed to the National PulseNet Database by the U.S. Food and Drug Administration from 2001 to 2008.

Imported foods must meet the same U.S. Food and Drug Administration (FDA) standards as domestic foods. The FDA determines whether an imported food is in compliance with the Federal Food, Drug, and Cosmetic Act. Pursuant to its regulatory activities, the FDA conducts compliance surveillance on imported foods offered for entry into the U.S. commerce. The National PulseNet Database is the molecular surveillance network for foodborne infections and is widely used to provide real-time subtyping support to epidemiologic investigations of foodborne diseases. FDA laboratories use pulsed-field gel electrophoresis to subtype foodborne pathogens recovered from imported foods and submit the molecular patterns to the National PulseNet Database at the Centers for Disease Control and Prevention. There were 60 isolates of Listeria monocytogenes in the FDA Field Accomplishment and Compliance Tracking System from 2001 to 2008 due to cheese imported from the following countries: Mexico (n=21 isolates), Italy (19), Israel (9), Portugal (5), Colombia (3), Greece (2), and Spain (1). We observed genetic diversity of L. monocytogenes isolates and genetic relatedness among strains recovered from imported cheese products coming to the United States from different countries. Consistent characterization of L. monocytogenes isolates recovered from imported cheeses, accompanied by epidemiologic investigations to ascertain human illness associated with these strains, could be helpful in the control of listeriosis acquired from imported cheeses.

Dietary supplements in a national survey: Prevalence of use and reports of adverse events.

OBJECTIVE: To examine information collected from the 2002 Health and Diet Survey regarding the use dietary supplements and self-reported health problems that the survey participants believed were related to dietary supplements. METHODS: The US Food and Drug Administration sponsors a Health and Diet Survey to track trends of consumer awareness, attitudes, and practices related to health and diet issues. By telephone, the 2002 Health and Diet Survey staff interviewed English-speaking noninstitutionalized adults aged 18 years or older in households in the 50 states and District of Columbia. Survey respondents were queried as to whether or not they had taken a dietary supplement during the past year and if they had experienced any health problem that they attributed to supplement use. RESULTS: Seventy-three percent of US noninstitutionalized adults aged 18 years or older who spoke English and resided in households with telephones used a dietary supplement in the previous 12 months and 4% of them had experienced an adverse event that they believed might be related to dietary supplement use. Eighty-five percent of supplement users reported taking multivitamins/multiminerals and 13.3% of adverse events reported were attributed to multivitamins/multiminerals. A higher proportion of supplement users with adverse events than users without adverse events were concurrently taking supplements and prescription drugs or were taking supplements instead of prescription drug to treat or prevent a health condition. CONCLUSIONS: This self-reported data describes the prevalence of supplement use and related adverse events. Multivitamins/multiminerals accounted for much of the supplements use and was attributed to a little more than 10% of the adverse events reported. Food and nutrition-professionals and other health care professionals should take special care to learn about their patients' use of these products.

Consumption of dietary supplements containing Citrus aurantium (bitter orange)--2004 California Behavioral Risk Factor Surveillance Survey (BRFSS).

BACKGROUND: Following the marketing ban of ephedra-containing supplements in April 2004, many manufacturers substituted the herb Citrus aurantium for ephedra and marketed the products as "ephedra-free" supplements. Extracts of C. aurantium contain synephrine, a sympathomimetic alkaloid. OBJECTIVE: To determine the prevalence of consumption of dietary supplements containing C. aurantium in California during 2004. METHODS: We used the 2004 California Behavioral Risk Factor Surveillance Survey to determine the prevalence of consumption of dietary supplements containing C. aurantium in California during 2004. RESULTS: Two percent (n = 70) of the 4140 survey respondents reported taking a dietary supplement containing C. aurantium in the previous year. Reasons stated included energy enhancement, weight loss, and appetite suppression. Compared with nonusers, users were more likely to report being single, aged 18-34 years, and Hispanic; consuming 3 or more alcoholic drinks on days that they imbibed; and having a heavier body mass index. Among the 5 users who reported experiencing an adverse event that they attributed to the supplement, 3 indicated that the severity was mild. CONCLUSIONS: Given that supplements containing ephedra were banned in April 2004, the results from this study may serve as a baseline estimate against which future studies of the use of C. aurantium products may be compared.
