Vitamin E Supplementation

To evaluate the efficacy of four early intramuscular injections of vitamin E given in addition to continuous minimal oral vitamin E supplementation, 168 very low-birth-weight infants (≤1,500 g) have enrolled in a randomized, double-masked, clinical study. All infants received vitamin E orally, 100 mg/kg/d. In addition, on days 1, 2, 4, and 6, seventy-nine infants received vitamin E intramuscularly, 15, 10, 10, and 10 mg/kg, respectively. On the same days, 89 control infants received placebo intramuscular injections. Multivariate analysis of the 135 infants who survived ≥10 weeks showed no significant difference in the development of severe retrolental fibroplasia between these two supplementation schedules (P = .86). Plasma vitamin E levels never exceeded a mean of 3.3 mg/100 mL, and no toxicity was observed. Ultrastructural analyses of seven pairs of whole eye donations from infants receiving IM vitamin E demonstrated identical kinetics of gap junction formation between adjacent spindle cells as compared with 13 pairs of whole eye donations from control infants (P > .3). Therefore, oral vitamin E supplementation affords retinal protection against the development of severe retrolental fibroplasia when initiated on the first day of life and maintained continuously until retinal vascularization is complete.

Clinical Observations

To the Editor.— The letter to the editor by Johnson et al1 and studies by others regarding vitamin E prophylaxis for retinopathy of prematurity suggest that further research into the prevention of retinopathy of prematurity should not be limited to vitamin E. On the basis of clinical observations we reported that d-penicillamine treatment in the neonatal period was associated with a marked decrease in the incidence of severe retrolental fibroplasia among the very low birth weight infants.2

Vitamin E Supplementation

1. The efficacy of oral vitamin E supplementation in preventing the early anaemia of the premature infant was assessed in a 10-week double-blind trial. Forty-two babies received either a placebo or 5 or 15 mg supplementary vitamin E/d with oral feeding. No infant received less than the recommended vitamin E:polyunsaturated fatty acid (E:PUFA) value of 0.6. No iron supplement was given.2. Weekly full blood counts were taken, and plasma vitamin E assay and in vitro haemolysis tests performed on blood sampled on day 1, and also at 6 and 10 weeks of age. All blood withdrawn and transfused and all feeds were documented.3. Thirty-six (86%) of the babies had a plasma vitamin E level at birth below the accepted adult norm, i.e. < 5200 μg/l. At 6 weeks of age thirty-three (79%) and at 10 weeks thirty-five (83%) of the babies had levels within the normal adult range. No baby showed either clinical or haematological evidence of a vitamin E deficiency state during the trial.4. It is concluded that in the absence of Fe supplementation and observing the minimum recommended E:PUFA value, contemporary feeding practices allow for the absorption of sufficient vitamin E by the premature baby to prevent the development of an early haemolytic anaemia.5. No significant relation was found between plasma vitamin E levels and the degree of peroxide haemolysis.

Objective: Both Vitamin C and Vitamin E supplementation were associated with reduction in blood pressure (BP) in observational studies, although, results of clinical trials are inconsistent. The objective of our study is to conduct a clinical trial to observe the effects of oral supplementation of Vitamin C and Vitamin E on BP. Methods: About 60 non-teaching staffs of our college with systolic BP more than 130 mmHg and diastolic BP more than 90 mmHg were taken as subjects and divided into two groups. Initial BP and BP after oral Vitamin C, 500 mg/day for a period of 12weeks to Group 1 and initial BP and BP after oral Vitamin E, 200 IU/day, for a period of 12 weeks to Group 2 were recorded. Results: Statistical analysis was done by paired t-test, analysis of variance (ANOVA), and least significant difference (LSD) tests. *p<0.05 was considered statistically significant. Systolic 2 and diastolic 2 – after 3 months of supplementation showed 0.161 and 0.161 which is not significant. ANOVA and LSD tests show no significant results. Conclusion: Long-term trials on the effects of Vitamin C and Vitamin E supplementation on BP and clinical events are needed.

Vitamin E Supplementation

Smith-Lemli-Opitz syndrome (SLOS) is a severe monogenic disorder resulting in low cholesterol and high 7-dehydrocholesterol (7-DHC) levels. 7-DHC-derived oxysterols likely contribute to disease pathophysiology, and thus antioxidant treatment might be beneficial because of high oxidative stress. In a three-year prospective study, we investigated the effects of vitamin E supplementation in six SLOS patients already receiving dietary cholesterol treatment. Plasma vitamin A and E concentrations were determined by the high-performance liquid chromatography (HPLC) method. At baseline, plasma 7-DHC, 8-dehydrocholesterol (8-DHC) and cholesterol levels were determined by liquid chromatography–tandem mass spectrometry (LC-MS/MS) method. The clinical effect of the supplementation was assessed by performing structured parental interviews. At baseline, patients were characterized by low or low–normal plasma vitamin E concentrations (7.19–15.68 μmol/L), while vitamin A concentrations were found to be normal or high (1.26–2.68 μmol/L). Vitamin E supplementation resulted in correction or significant elevation of plasma vitamin E concentration in all patients. We observed reduced aggression, self-injury, irritability, hyperactivity, attention deficit, repetitive behavior, sleep disturbance, skin photosensitivity and/or eczema in 3/6 patients, with notable individual variability. Clinical response to therapy was associated with a low baseline 7-DHC + 8-DHC/cholesterol ratio (0.2–0.4). We suggest that determination of vitamin E status is important in SLOS patients. Supplementation of vitamin E should be considered and might be beneficial.

To determine whether early intramuscular vitamin E supplementation influences the incidence of intraventricular hemorrhage (IVH) in infants with birth weight ≤1,500 g, data were analyzed from 134 infants enrolled on a protocol to evaluate the efficacy of intramuscular plus oral vitamin E v oral supplementation alone in the treatment of retrolental fibroplasia. All 134 infants received, via nasogastnic tube, 100 mg/kg/d of vitamin E daily (dl-α-tocopheryl acetate in MCT [medium-chain triglyceride] oil; 150 mosM) for at least 8 weeks with the first dose administered within the first eight hours of life. Sixty-four patients received, in addition, intramuscular vitamin E on days 1, 2, 4, and 6 of life and 70 patients received placebo injections in a randomized double-blind fashion. In the first week, vitamin E plasma levels were significantly higher in the 64 patients given intramuscular vitamin E. In spite of this difference no change in the incidence of sepsis or necrotizing enterocolitis was observed. Both the incidence and severity of intraventricular hemorrhage were reduced significantly in the patients given intramuscular vitamin E as compared to the patients given placebo (P = .013 and P = .04, respectively). The data suggest that vitamin E, a natural antioxidant, may play an important role in protecting the CNS microcirculation from the effects of hypoxic/ischemic injury.

The purpose of the present study was to investigate the effect of experimental T-2 toxin load (2.35 mg/kg of feed) and vitamin E supply in the drinking water (10.5 mg/bird/day) on vitamin E levels of the blood plasma and liver in broiler chickens in a 14-day experiment. It was found that T-2 toxin load did not influence vitamin E content of the blood plasma except at day 3 after the toxin load when a moderate increase was detected in plasma vitamin E. No significant changes were found in vitamin E content of the liver. The simultaneous use of high-dose vitamin E supplementation and T-2 toxin load caused a significantly higher plasma vitamin E content but the changes were less expressed in the group subjected to T-2 toxin load. Vitamin E supply also resulted in a marked and significant increase in vitamin E concentrations of the liver on days 3 and 7 even in the T-2 loaded group, but this concentration significantly decreased thereafter. The results show that T-2 contamination of the diet has an adverse effect on the utilisation of vitamin E in broiler chickens.

Twelve Holstein cows in each of two replicates were used to determine the effect of forage type and vitamin E supplementation on the oxidative stability of milk. Alfalfa or corn silage was fed ad libitum as the sole roughage, with a concentrate to milk ratio of 1:2.5. Half the cows on each forage were fed 7000 IU d−1 of dL-α-tocopherol acetate top-dressed on the concentrate in two feedings per day over a 4-wk period. Cows consuming the alfalfa silage had higher (P < 0.05) plasma vitamin E content, but there were no differences in milk vitamin E or flavor due to forage type. Supplementing the diets with vitamin E resulted in higher (P < 0.01) vitamin E content of plasma and milk and improved milk oxidative stability. There was an interaction (P = 0.03) between forage type and vitamin E supplementation for oxidative flavor score in week 2. Supplementing the corn silage diet with 7000 IU d−1 of vitamin E resulted in almost complete elimination of oxidized flavor in milk within 1 wk of starting supplementation. However, supplementing the alfalfa silage diet had no effect on flavor over the first 3 wk of feeding. It is apparent that the vitamin E content of milk is not the sole determinant of its oxidative stability. Key words: Spontaneous oxidation, flavor, milk, vitamin E, alfalfa, corn silage, cow

Plasma Vitamin E

Vitamin E is believed to play a preventive role in diseases associated with oxidative stress. The aims of the present study were to quantify vitamin E intake levels and plasma concentrations and to assess dietary vitamin E adequacy in Irish adults. Intake data from the National Adult Nutrition Survey were used; plasma samples were obtained from a representative cohort of survey participants. Plasma α- and γ-tocopherol concentrations were measured by HPLC. The main sources of vitamin E in the diet were ‘butter, spreadable fats and oils’ and ‘vegetables and vegetable dishes’. When vitamin E intake from supplements was taken into account, supplements were found to be the main contributor, making a contribution of 29·2 % to vitamin E intake in the total population. Supplement consumers had significantly higher plasma α-tocopherol concentrations and lower plasma γ-tocopherol concentrations when compared with non-consumers. Consumers of ‘vitamin E’ supplements had significantly higher vitamin E intake levels and plasma α-tocopherol concentrations compared with consumers of other types of supplements, such as multivitamin and fish oil. Comparison with the Institute of Medicine Estimated Average Requirement of 12 mg/d indicated that when vitamin E intake from food and supplement sources was taken into account, 100 % of the study participants achieved the recommended intake levels. When vitamin E intake from food sources was taken into account, only 68·4 % of the females were found to achieve the recommended intake levels compared with 99·2 % of the males. The results of the present study show that dietary vitamin E intake has a significant effect on plasma α- and γ-tocopherol concentrations. Furthermore, they show that the consumption of supplements is a major contributor to overall intake and has a significant effect on plasma vitamin E concentrations in the Irish population.
