Rheum rhaponticum Extract (ERr 731): Postmarketing Data on Safety Surveillance and Consumer Complaints.

CONTEXT: Postmarketing surveillance data for a commercially available extract of Rheum rhaponticum (ERr 731) have not been published since the beginning of the reporting in 1993 in Germany about adverse events (AEs) that were believed to be associated with it. The extract is derived from the plant's roots and is indicated for menopausal relief. In Germany, the extract has been marketed as Phytoestrol N and other related products-Phyto-Strol, Phyto-Strol Loges, and Phyto-Strol compact and as femi-loges. In the United States and Canada and in South Africa, the product had been marketed as Estrovera. OBJECTIVE: The study's objective was to summarize the AE reports from Germany from 1993 to June 2014 and also to assess consumers' complaints in North America and South Africa from the date of the extract's launch to June 2014. DESIGN: AE reports recorded by 2 German holders of marketing authorizations, Chemisch-Pharmazeutische Fabrik Göppingen, for Phytoestrol N, and Dr. Loges + Co. GmbH, for femi-loges, were collected and analyzed. Consumers' complaints in North America and South Africa that had been captured by the US distributor of Estrovera were also collected and analyzed. RESULTS: From 1993 to June 2014, approximately 140 million daily doses of the extract were placed on the German market, and 124 AE reports were recorded. The most common of those AEs were hypersensitivity, with 74 reactions, and gastrointestinal symptoms, with 47 reactions. From January 2009 to June 2014, approximately 13 million tablets of the supplement were sold in North America, and 79 complaints from consumers associated with a physical response to it had been recorded. The main complaints were gastrointestinal symptoms, with 23 cases, and failure to work as suggested, with 22 cases. From the date of the product's launch in South Africa in February 2011 to June 2014, no consumer complaints have been reported. CONCLUSIONS: The records related to postmarketing surveillance and consumers' complaints suggest that the extract of R rhaponticum is generally safe for consumption.

Nutritional Approach for Relief of Joint Discomfort: A 12-week, Open-case Series and Illustrative Case Report.

CONTEXT: Tetrahydro iso-α acids (THIAAs), derived from Humulus lupulus (hops), have demonstrated anti-inflammatory effects in vitro and in an animal model of rheumatoid arthritis (RA). Undenatured type 2 collagen has been found to be effective in clinical studies in RA and osteoarthritis (OA). OBJECTIVE: The study intended to evaluate the efficacy and safety of a proprietary tablet containing 150 mg of n-enriched THIAA (nTHIAA) and 10 mg of undenatured type 2 collagen (UC-II) (containing 25% UC-II) in patients with arthritis. DESIGN: The study was an open-label case series. This article also includes a case history for 1 participant. SETTING: The study was conducted at the Functional Medicine Research Center (FMRC) in Gig Harbor, WA, USA, from February 2013-June 2013. PARTICIPANTS: Participants were 17 adults, 12 women, and 5 men aged 39-69 y, who had chronic joint pain involving various joints, 13 with probable OA and 4 with possible RA. INTERVENTION: Participants took 2 tablets of nTHIAA + UC-II 2 ×/d with meals for 12 wk. OUTCOME MEASURES: Participants completed arthritis-related and quality-of-life questionnaires, at weeks 2, 4, 8, and 12: (1) the visual analog scale for pain (VAS-P); (2) the medical symptoms questionnaire (MSQ), with the analysis particularly focusing on the joint/muscle subscale and total scores; (3) the health and wellness outcome questionnaire (MOS-SF36), with the analysis particularly focusing on the physical and mental subscales; (4) the arthritis impact questionnaire (AIQ), with the analysis particularly focusing on the arthritis symptoms and daily living subscales; (5) the health assessment questionnaire (HAQ-DI) with the analysis particularly focusing on question 26 (Q26), which indicates overall pain during the week prior to the survey; and (6) the arthritis impact measurement scales 2 (AIMS2). At 12 wk, participants also completed the visual analog scale for efficacy (VAS-E). RESULTS: All participants completed the 12-wk evaluation, and all reported improvements in pain. Significant improvements in scores on the questionnaires were observed as early as 2 wk. For example, the total score on the MSQ was significantly decreased from a mean of 20.76 ± 2.90 (SE) at baseline to 12.24 ± 2.81 after 2 wk (P < .001). At 12 wk, the participants rated the supplement's efficacy at 7.6 ± 0.6 of 10. At baseline, 13 of the 17 participants were using analgesics for joint pain, compared with only 4 participants at 12 wk. Two of those 4 had reduced their analgesic dosages. The studied supplement was well tolerated, and no serious side effects occurred. CONCLUSIONS: The supplement containing nTHIAA and UC-II is safe and efficacious in participants with chronic joint pain.

Effect of DHA-containing formula on growth of preterm infants to 59 weeks postmenstrual age.

Between May 1993, and September 1994, a randomized, blinded clinical trial was conducted to evaluate measures of growth and body composition in 63 (32 males; 31 females) healthy, low-birth-weight infants (940-2250 g) who were randomly assigned to an infant formula with docosahexaenoic acid (22:6n3, DHA, 0.2 wt%) from fish oil or to a control formula. A preterm formula with or without DHA was fed beginning at 7-10 days prior to hospital discharge through 43 weeks postmenstrual age (PMA). Then, from 43-59 weeks PMA, infants were fed a term infant formula with or without a corresponding amount of DHA. Growth (weight, length, head circumference), regional body fatness (triceps, subscapular, suprailiac skinfold thicknesses), circumferences (arm, abdominal, chest), and estimates of body composition determined by total body electrical conductivity (TOBEC) (fat-free mass [FFM]) were evaluated. Growth was slower in males fed the DHA formula. They had significantly (P < 0.05) smaller gains in weight, length, and head circumference between study enrollment to 59 weeks PMA than those fed the control formula. At 51 weeks PMA, males in the DHA group had significantly smaller head circumferences (P < 0.05) and lower FFM (P < 0.05). At 59 weeks PMA, males in the DHA group weighed less (P < 0.05), had shorter recumbent lengths (P < 0.01), smaller head circumferences (P < 0.05), and lower FFM (P < 0.01) than those fed the control formula. Energy intakes from formula (kcal/d), however, were lower at 51 weeks (P < 0.05) and 59 weeks (P < 0.05) PMA in males fed the DHA formula. Adjusted for body weight (kcal/kg/d), mean energy intakes from formula at 51 and 59 weeks PMA were not significantly different between feeding groups. The differences in recumbent length, head circumference, and FFM remained statistically significant after controlling for energy and protein intakes (P < 0.01). For all males, neither FFM nor total body fat (TBF), when expressed as a percentage of total body weight, differed significantly between feeding groups. Among females, there were no significant differences between the feeding groups in measures of growth, body composition, or energy intake. The results indicated that infant formula with fish oil containing DHA and EPA in a 5:1 ratio had a significant, negative effect on growth and body composition in males during the first 6 months of life. It is not clear why the growth deficits were limited to males and not females. The eicosanoids, bioactive metabolites of omega-3 and omega-6 fatty acids, may mediate several important growth hormones. The present results do not support the addition of DHA alone in infant formulas. Am. J. Hum. Biol. 11:457-467, 1999. Copyright 1999 Wiley-Liss, Inc.

Lactose-free milk protein-based infant formula: impact on growth and gastrointestinal tolerance in infants.

Lactose, the major carbohydrate in human milk and standard milk-based formulas, provides energy for growth in infants. The use of lactose-free milk protein-based infant formulas has increased in the United States. However, clinical studies of their impact on growth, safety, and gastrointestinal tolerance in infants are limited. Thus, a prospective, blinded, randomized clinical trial was conducted in healthy, normal-term infants fed an experimental lactose-free milk protein-based formula (NoLAC; n = 63) versus a standard commercial lactose-containing milk-based formula (LAC; n = 65) for 112 days. Growth (weight, length, and head circumference) was similar and normal in both groups (weight gain: NoLAC = 31.1 ± 0.9 g/day, LAC = 29.4 ± 0.9 g/day, mean ± SEM; P = .895). Serum biochemistries for both groups were within infants' normal reference ranges. Both groups had comparable tolerance but the NoLAC group had softer stools and lower spit-ups. Thus, the study suggests that absence of lactose in milk-based formula does not adversely affect normal growth in term infants.

Visual, cognitive, and language assessments at 39 months: a follow-up study of children fed formulas containing long-chain polyunsaturated fatty acids to 1 year of age

Objective. Docosahexaenoic acid (DHA)and arachidonic acid (ARA) are long-chain polyunsaturated fatty acids found in breast milk and recently added to infant formulas...

Reduced bone mineralization in infants fed palm olein-containing formula: a randomized, double-blinded, prospective trial.

OBJECTIVE: Palm and palm olein (PO) oils are used in some infant formula fat blends to match the fatty acid profile of human milk, but their presence has been shown to lower calcium and fat absorption. We aimed to determine if the reported differences in calcium absorption could affect skeletal development by comparing bone mineral accretion in healthy term infants fed a milk-based formula with (PMF) or without PO. METHODS: Whole body bone mineralization was evaluated in healthy term infants fed 1 of 2 coded, commercially available, ready-to-feed infant formulas in a randomized, double-blind, parallel study. Subjects were fed either 1). PMF formula (Enfamil with iron; Mead Johnson Division of Bristol Myers, Evansville, IN; N = 63) containing PO/coconut/soy/high-oleic sunflower oils (45/20/20/15% oil); or 2). milk-based formula without PO (Similac with iron; Ross Products Division Abbott Laboratories, Columbus, OH; N = 65), containing high-oleic safflower/coconut/soy oils (40/30/30% oil) from enrollment by 2 weeks after birth until 6 months. Anthropometrics and formula intake were determined monthly; total body bone mineral content (BMC) and bone mineral density (BMD) were measured at baseline, 3, and 6 months of age using dual energy x-ray absorptiometry. RESULTS: Intent-to-treat analyses indicated no significant differences between feeding groups in weight, length, head circumference, or formula intake throughout the study. BMC and BMD were not different at baseline but repeated measures analyses show that infants fed PMF had significantly lower BMC and BMD at 3 and 6 months. CONCLUSIONS: Healthy term infants fed a formula containing PO as the predominant oil in the fat blend had significantly lower BMC and BMD than those fed a formula without PO. The inclusion of PO in infant formula at levels needed to provide a fatty acid profile similar to that of human milk leads to lower bone mineralization.

Visual, cognitive, and language assessments at 39 months: a follow-up study of children fed formulas containing long-chain polyunsaturated fatty acids to 1 year of age.

OBJECTIVE: Docosahexaenoic acid (DHA) and arachidonic acid (ARA) are long-chain polyunsaturated fatty acids found in breast milk and recently added to infant formulas. Their importance in infant nutrition was recognized by the rapid accretion of these fatty acids in the brain during the first postnatal year, reports of enhanced intellectual development in breastfed children, and recognition of the physiologic importance of DHA in visual and neural systems from studies in animal models. These considerations led to clinical trials to evaluate whether infant formulas that are supplemented with DHA or both DHA and ARA would enhance visual and cognitive development or whether conversion of linoleic acid and alpha-linolenic acid, the essential fatty acid precursors of ARA and DHA, respectively, at the levels found in infant formulas is sufficient to support adequately visual and cognitive development. Visual and cognitive development were not different with supplementation in some studies, whereas other studies reported benefits of adding DHA or both DHA and ARA to formula. One of the first trials with term infants that were fed formula supplemented with DHA or both DHA and ARA evaluated growth, visual acuity (Visual Evoked Potential; Acuity Card Procedure), mental and motor development (Bayley Scales of Infant Development), and early language development (MacArthur Communicative Developmental Inventories). Growth, visual acuity, and mental and motor development were not different among the 3 formula groups or between the breastfed and formula-fed infants in the first year of life. At 14 months of age, infants who were fed the formula with DHA but no ARA had lower vocabulary production and comprehension scores than infants who were fed the unsupplemented control formula or who were breastfed, respectively. The present follow-up study evaluated IQ, receptive and expressive vocabulary, visual-motor function, and visual acuity of children from the original trial when they reached 39 months of age. METHODS: Infants were randomized within 1 week after birth and fed a control formula (n = 65), one containing DHA (n = 65), or one containing both ARA and DHA (n = 66) to 1 year of age. A comparison group (n = 80) was exclusively breastfed for at least 3 months after which the infants continued to be exclusively breastfed or were supplemented with and/or weaned to infant formula. At 39 months, standard tests of IQ (Stanford Binet IQ), receptive vocabulary (Peabody Picture Vocabulary Test-Revised), expressive vocabulary (mean length of utterance), visual-motor function (Beery Visual-Motor Index), and visual acuity (Acuity Card Procedure) were administered. Growth, red blood cell fatty acid levels, and morbidity also were evaluated. RESULTS: Results were analyzed using analysis of variance or linear regression models. The regression model for IQ, receptive and expressive language, and the visual-motor index controlled for site, birth weight, sex, maternal education, maternal age, and the child's age at testing. The regression model for visual acuity controlled for site only. A variable selection model also identified which of 22 potentially prognostic variables among different categories (feeding groups, the child and family demographics, indicators of illness since birth, and environment) were most influential for IQ and expressive vocabulary. A total of 157 (80%) of the 197 infants studied at 12 months participated in this follow-up study. Characteristics of the families were representative of US families with children up to 5 years of age, and there were no differences in the demographic or family characteristics among the randomized formula groups. As expected, the formula and breastfed groups differed in ethnicity, marital status, parental education, and the prevalence of smoking. Sex, ethnicity, gestational age at birth, and birth weight for those who participated at 39 months did not differ from those who did not. The 12-month Bayley mental and motor scores and 14-month vocabulary scores of the children who participated also were were not different from those who did not. At 39 months, IQ, receptive and expressive language, visual-motor function, and visual acuity were not different among the 3 randomized formula groups or between the breastfed and formula groups. The adjusted means for the control, ARA+DHA, DHA, and breastfed groups were as follows: IQ scores, 104, 101, 100, 106; Peabody Picture Vocabulary Test, 99.2, 97.2, 95.1, 97.4; mean length of utterance, 3.64, 3.75, 3.93, 4.08; the visual-motor index, 2.26, 2.24, 2.05, 2.40; and visual acuity (cycles/degree), 30.4, 27.9, 27.5, 28.6, respectively. IQ was positively associated with female sex and maternal education and negatively associated with the number of siblings and exposure to cigarette smoking in utero and/or postnatally. Expressive language also was positively associated with maternal education and negatively associated with the average hours in child care per week and hospitalizations since birth but only when the breastfed group was included in the analysis. The associations between maternal education and child IQ scores are consistent with previous reports as are the associations between prenatal exposure to cigarette smoke and IQ and early language development. Approximately one third of the variance for IQ was explained by sex, maternal education, the number of siblings, and exposure to cigarette smoke. Growth achievement, red blood cell fatty acid levels, and morbidity did not differ among groups. CONCLUSIONS: We reported previously that infants who were fed an unsupplemented formula or one with DHA or with both DHA and ARA through 12 months or were breastfed showed no differences in mental and motor development, but those who were fed DHA without ARA had lower vocabulary scores on a standardized, parent-report instrument at 14 months of age when compared with infants who were fed the unsupplemented formula or who were breastfed. When the infants were reassessed at 39 months using age-appropriate tests of receptive and expressive language as well as IQ, visual-motor function and visual acuity, no differences among the formula groups or between the formula and breastfed groups were found. The 14-month observation thus may have been a transient effect of DHA (without ARA) supplementation on early vocabulary development or may have occurred by chance. The absence of differences in growth achievement adds to the evidence that DHA with or without ARA supports normal growth in full-term infants. In conclusion, adding both DHA and ARA when supplementing infant formulas with long-chain polyunsaturated fatty acids supports visual and cognitive development through 39 months.
