    ABSTRACT: Isotope dilution methods have been successfully used to estimate vitamin A status in human populations as well as to evaluate the impact of vitamin A interventions. The most commonly applied isotope dilution method is the retinol isotope dilution technique, which is based on the 1989 “Olson equation” for estimating total body vitamin A stores (sometimes equated to liver vitamin A) after an oral dose of labeled vitamin A. The equation relies on several factors related to absorption and retention of the dose, the equilibration of label in plasma vs. liver, and timing of a blood sample for measurement of labeled vitamin A. Here, the assumptions underlying these factors are discussed, and new results based on applying model-based compartmental analysis [specifically, the Simulation, Analysis and Modeling software (WinSAAM)] to data on retinol kinetics in humans are summarized. A simplification of the Olson equation, in which plasma tracer is measured 3 days after administration of the oral dose and several factors are eliminated, is presented. The potential usefulness of the retinol isotope dilution technique for setting vitamin A requirements and assessing vitamin A status in children, as well as the confounding effects of inflammation and likely variability in vitamin A absorption, are also discussed.

    ABSTRACT: A variety of methods exist to assess vitamin A status of groups and populations. Vitamin A status is usually defined by the liver retinol concentration. Most indicators of status do not measure or estimate liver stores of retinol. Clinical signs only have utility when liver reserves are almost exhausted, and serum retinol concentrations have utility in the zone of overt deficiency. Dose response tests offer more coverage, but cannot distinguish among liver vitamin A stores in the adequate through toxic range. Different countries continue, or are beginning, to add preformed vitamin A to a variety of staple foods through fortification, and vitamin A supplements are still being distributed in many countries, especially to preschool children. Further, provitamin A biofortified crops are currently being released in several countries. Assessing population vitamin A status in response to these interventions needs to move beyond serum retinol concentrations. Indicators that work in the excessive to toxic range of liver reserves are needed. To date, the only indirect indicator that has been validated in this range of liver reserves in animals and humans is the retinol isotope dilution test using deuterium or 13C, which spans the entire liver reserve continuum from deficiency through excess.

    ABSTRACT: Humans need vitamin A and obtain essential vitamin A by conversion of plant foods rich in provitamin A and/or absorption of preformed vitamin A from foods of animal origin. The determination of the vitamin A value of plant foods rich in provitamin A is important but has challenges. The aim of this paper is to review the progress over last 80 years following the discovery on the conversion of β-carotene to vitamin A and the various techniques including stable isotope technologies that have been developed to determine vitamin A values of plant provitamin A (mainly β-carotene). These include applications from using radioactive β-carotene and vitamin A, depletion-repletion with vitamin A and β-carotene, and measuring postprandial chylomicron fractions after feeding a β-carotene rich diet, to using stable isotopes as tracers to follow the absorption and conversion of plant food provitamin A carotenoids (mainly β-carotene) in humans. These approaches have greatly promoted our understanding of the absorption and conversion of β-carotene to vitamin A. Stable isotope labeled plant foods are useful for determining the overall bioavailability of provitamin A carotenoids from specific foods. Locally obtained plant foods can provide vitamin A and prevent deficiency of vitamin A, a remaining worldwide concern.

    ABSTRACT: The current use of serum retinol concentrations as a measurement of subclinical vitamin A deficiency is unsatisfactory for many reasons. The best technique available for vitamin A status assessment in humans is the measurement of total body pool size. Pool size is measured by the administration of retinol labelled with stable isotopes of carbon or hydrogen that are safe for human subjects, with subsequent measurement of the dilution of the labelled retinol within the body pool. However, the isotope techniques are time-consuming, technically challenging, and relatively expensive. There is also a need to assess different types of tracers and doses, and to establish clear guidelines for the use and interpretation of this method in different populations. Field-friendly improvements are desirable to encourage the application of this technique in developing countries where the need is greatest for monitoring the risk of vitamin A deficiency, the effectiveness of public health interventions, and the potential of hypervitaminosis due to combined supplement and fortification programs. These techniques should be applied to validate other less technical methods of assessing vitamin A deficiency. Another area of public health relevance for this technique is to understand the bioconversion of β-carotene to vitamin A, and its relation to existing vitamin A status, for future dietary diversification programs.

    ABSTRACT: This paper discusses some of the recent improvements in instrumentation used for stable isotope tracer measurements in the context of measuring retinol stores, in vivo. Tracer costs, together with concerns that larger tracer doses may perturb the parameter under study, demand that ever more sensitive mass spectrometric techniques are developed. GCMS is the most widely used technique. It has high sensitivity in terms of sample amount and uses high resolution GC, yet its ability to detect low isotope ratios is limited by background noise. LCMSMS may become more accessible for tracer studies. Its ability to measure low level stable isotope tracers may prove superior to GCMS, but it is isotope ratio MS (IRMS) that has been designed specifically for low level stable isotope analysis through accurate analysis of tracer:tracee ratios (the tracee being the unlabelled species). Compound-specific isotope analysis, where GC is interfaced to IRMS, is gaining popularity. Here, individual 13C-labelled compounds are separated by GC, combusted to CO2 and transferred on-line for ratiometric analysis by IRMS at the ppm level. However, commercially-available 13C-labelled retinol tracers are 2 - 4 times more expensive than deuterated tracers. For 2H-labelled compounds, GC-pyrolysis-IRMS has now become more generally available as an operating mode on the same IRMS instrument. Here, individual compounds are separated by GC and pyrolysed to H2 at high temperature for analysis by IRMS. It is predicted that GC-pyrolysis-IRMS will facilitate low level tracer procedures to measure body retinol stores, as has been accomplished in the case of fatty acids and amino acids. Sample size requirements for GC-P-IRMS may exceed those of GCMS, but this paper discusses sample preparation procedures and predicts improvements, particularly in the efficiency of sample introduction.

    ABSTRACT: Vitamin C has important physical and mental health benefits and plasma concentrations reflect recent intakes. Inflammation associated with any acute illness can lead to poor appetite and low food intake in older people. The aims of this report were to assess the prevalence and clinical significance of vitamin C deficiency among hospitalized acutely-ill older patients. Three hundred and twenty two patients (152 [47 %] female), aged 65 yrs. and over who took part in a randomized, double blind, placebo-controlled trial had their nutritional status assessed from anthropometric, hematological and biochemical data at baseline, and after 6 weeks and 6 months. Vitamin C was measured using a fluorimetric technique and logistic regression analysis was performed to determine the influence of a number of clinical indicators, including tissue inflammation measured using C-reactive protein on vitamin C concentrations. Clinical outcome measures including symptoms of depression were also compared between patients with vitamin C deficiency and those with normal levels. At baseline, 116 (36 %) patients had a vitamin C concentration below 11 µmol/L indicating biochemical depletion. The figures at 6 weeks and 6 months were 28 (22 %) and 44 (28 %) patients, respectively. Older age, male gender, smoking, increased dependency and tissue inflammation were associated with lower vitamin C concentrations. Patients with vitamin C biochemical depletion had significantly increased symptoms of depression compared with those with higher concentrations at baseline (p = 0.035) and at 6 weeks (p = 0.028). A high proportion of older patients had sub-optimal vitamin C status and this was associated with increased symptoms of depression.

    ABSTRACT: This study aims to investigate serum amyloid A, homocysteine, and biochemical-anthropometric measurements in post-menopausal women with and without metabolic syndrome (MS), and determine whether serum amyloid A and homocysteine are linked to MS among this group. This study was performed with 405 post-menopausal Thai volunteers with a mean age of 57.95 ± 5.90 years (135 subjects with MS and 270 subjects without MS). The levels of serum amyloid A, homocysteine, vitamins, glucose, and lipids were measured. Homocysteine levels were significantly higher in the group with MS than in that without MS (p < 0.001), whereas for serum amyloid A, vitamin A, vitamin E and vitamin B12, there were no significant differences. There were significant differences between the groups in folate, HDL-C, and anthropometric measurements (p < 0.001). Thirty seven percent of the group with MS and 14.1 % of the group without MS were classified as having hyperhomocysteinemia (p < 0.001). Furthermore, logistic regression analysis revealed that hyperhomocysteinemia (odds ratio (OR): 2.67, 95 % confidence interval (95 %CI): 1.57 - 4.58), low folate (OR: 1.79, 95 %CI: 1.11 - 2.89), and BMI (OR: 1.25, 95 %CI: 1.16 - 1.33) were significantly related to MS. These findings suggest that increased homocysteine levels and decreased folate concentrations may influence susceptibility to MS and this effect may be an early event in the development of cardiovascular diseases among post-menopausal women. Therefore, there is a need to evaluate homocysteine levels, especially among post-menopausal Thai women.

    ABSTRACT: Severe vitamin D deficiency can be treated with oral loading doses of cholecalciferol. Our objective was to develop an algorithm to accurately calculate the amount of cholecalciferol needed for a loading dose, and what factors should be taken into account. Two studies were conducted on subjects with Vitamin D deficiency. Study 1 was observational, retrospective and included 88 subjects treated with a daily supplementation of cholecalciferol. 60 of these furthermore received a loading dose, calculated by an algorithm.Study 2 was prospective and included 29 subjects treated with a cholecalciferol loading dose, calculated by an algorithm developed based on data from study 1, which included BMI. Baseline 25OH-vit.D was below 25 nmol/L (study 1) and 23 nmol/L (study 2). Subjects were given a single loading dose of cholecalciferol, averaging 172,000 IU (study 1) and 212,000 IU (study 2), based on their baseline 25OH-vit.D level.25OH-vit.D increased by 35 nmol/L (study 1) and 56 nmol/L (study 2)(range 113.0, SD 29.79) respectively. In study 2 the increase lead to an end 25OH-vit.D of 79 nmol/L - not significantly different from the target value of 80 nmol/L (P = 0.46). The increase in 25OH-vit.D in study 1 was significantly lower than in study 2 (P<0.001). When calculating loading doses of cholecalciferol, taking subject BMI into account gives a better estimate of the loading dose of vitamin D3 needed to treat vitamin D deficiency. It does not, however, remove the large interindividual variation in dose-response.

    ABSTRACT: Obesity has been associated with vitamin D deficiency and increased oxidative stress, which can lead to the dysregulation of adipokines and inflammation. The aim of the present work was to examine the association of vitamin D status [25(OH)D] on inflammatory related markers in overweight/obese children. A total of 137 Spanish schoolchildren between 9 and 12 years of age (31.4 % with overweight/obesity) were studied. Being overweight was defined as BMI ≥ 85th percentile and obesity as BMI ≥ 97th percentile using the reference tables of Hernández. Serum 25(OH)D concentrations were measured by chemiluminescent assay. Plasma tumor necrosis factor (TNF-α) and interleukin-6 (IL-6) were measured by immunoenzyme assay. Serum adiponectin was determined using an ELISA kit. Serum high-sensitivity C-reactive protein (hs-PCR) was tested by immunonephelometry. IL-6 concentrations were higher in the overweight/obese children with deficient serum 25(OH)D (< 20 ng/mL) than in those in this group but whose serum 25(OH)D concentrations were adequate (≥ 20 ng/mL). Serum 25(OH)D was inversely associated with IL-6 concentrations in the overweight/obese subjects taking into account different covariates; thus, for every 1 ng/mL rise in the former, the latter fell by 0.160 pg/mL (β = - 0.160 ± 0.068; R2 = 0.131; p = 0.023). The obese subjects with concentrations of ≥ 25 ng/mL had lower hs-CRP values compared to those with concentrations of < 25 ng/mL (0.053 ± 0.035 vs. 0.356 ± 0.613 mg/dL; p = 0.035). Low serum 25(OH)D was significantly associated high serum IL-6 in overweight/obese children, and with increased hs-CRP in obese children.

    ABSTRACT: This study was designed to assess oxidative damage and cell apoptosis in the uterus of rats with streptozotocin (STZ)-induced diabetes. The role of vitamin E (VE) and/or folic acid (FA) in the protection from such damage was also evaluated. The treatments were performed for 4 weeks on six groups of rats: 1) normal control 2) diabetic control 3) diabetic rats receiving olive oil as a vehicle (without VE) 4) diabetic rats treated with VE (200 mg/kg) in olive oil 5) diabetic rats treated with FA (25 mg/kg) and 6) diabetic rats treated with VE + FA (200 and 25 mg/kg, respectively). We measured the malondialdehyde level (MDA), glutathione content (GSH) and the activity of GSH peroxidase (GPx), GSH reductase (GR) and catalase. Changes in caspase-3 activity were quantified in uterine tissue to assess the rate of apoptosis. In the rat uterine tissues, MDA content and caspase-3 activity were significantly elevated, while GPx, GR and CAT activities and the GSH level were significantly decreased in the diabetic control compared with those in normal rats (p < 0.05). The combination of the vitamins (VE + FA) restored uterine GSH content and enzymatic activities of GPx, GR and CAT and reduced the MDA level (p < 0.05). A prominent reduction in apoptosis of uterine cells was detected in diabetic rats treated with two vitamins (p < 0.05). Overall, VE alone, not FA, produced results similar to those of the VE + FA combination. Thus, in the uterine tissue of diabetic rats, diabetes complications (that are caused by oxidative damage and apoptosis induction) can be prevented by the systemic administration of VE and FA.
