Avaliação da suplementação materna com megadose de vitamina a sobre os níveis de retinol e alfa-tocoferol no colostro

The vitamins A and E are recognizably important in the initial stages of life and the newborn depends on nutritional adequacy of breast milk to meet their needs. These vitamins share routes of transport to the tissues and antagonistic effects have been observed in animals after supplementation with vitamin A. This study aimed to verify the effect of maternal supplementation with vitamin A megadose (200,000 UI) in the immediate post-partum on the concentration of alpha-tocopherol in colostrum. Healthy parturient women attended at a public maternity natalensis were recruited for the study and divided into two groups: control (n = 37) and supplemented (n = 36). Blood samples of colostrum and milk were collected until 12 hours after delivery. The women of the supplemented group was administered a retynil palmitate capsule and 24 hours after the first collection was obtained the 2nd sample of colostrum in two groups for analysis of retinol and alpha-tocopherol in milk. The mean retinol concentration of 50,7 ± 14,4 μg/dL (Mean ± standard deviation) and alpha-tocopherol of 1217.4 ± 959 mg/dL in the serum indicate the nutritional status biochemical appropriate. Supplementation with retynil palmitate resulted in increase not only retinol levels in the colostrum of the supplemented group (p = 0.002), but also the concentration of alpha-tocopherol (p = 0.04), changing from 1456.6 ± 1095.8 mg/dL to 1804.3 ± 1432.0 mg/dL (milk 0 and 24 respectively) compared to values in the control group, 984.6 ± 750.0 mg/dL and 1175.0 ± 730.8 mg/dL. The women had different responses to supplementation, influenced by baseline levels of retinol in colostrum. Those with previous by low levels of retinol in colostrum (<60 mg/dL) had increased the concentration of alpha-tocopherol in milk, whereas those with adequate levels (> 60 mg/dL), showed a reduction after supplementation. Supplementation with retinol palmitate is an important intervention in situations of high risk for vitamin A deficiency, when considering the need to maternal supplementation, since the excess vitamin can offer unfavorable interactions between nutrients essential for the mother-child group

Efeito Da Suplementação Materna Com Palmitato De Retinila Sobre A Concentração De Retinol No Colostro Em Condições De Jejum E Pós-Prandial.

Vitamin A is important in many essential body processes and its deficiency results in serious consequences for human health. Breast milk is the only source of this vitamin for children that are exclusively breastfed. Analysis of vitamin A in mother s milk is important because its concentration is related to maternal vitamin A status and to its ingestion by the mother during pregnancy. The aim of the present study was to assess the effect of maternal supplementation with retynil palmitate on the concentration of colostrum retinol under fasting and postprandial conditions. A total of 149 nursing mothers were recruited at the Januário Cicco Maternity School (Natal, Brazil) and allocated to two groups: Comparison (n = 69) and Test (n = 80). Blood and colostrum (in fasting and postprandial conditions) samples were collected up to 24hs after delivery. Serum retinol and colostrum levels were analyzed by high-performance liquid chromatography. The serum retinol level of 41.6 ± 12.7μg/dL (mean ± standard deviation) indicates adequate biochemical nutritional status. Colostrum retinol level was not influenced by serum retinol levels under any of the conditions established. In the colostrum, the retinol concentration in the unsupplemented test group was 67.3 ± 37.7 μg/dL under fasting and 80.3 ± 35.1 μg/dL under postprandial conditions (p<0.05), showing an increase of 19.3%. In the supplemented test group the values were 102.6 ± 57.3 μg/dL and 133.4 ± 78.3 μg/dL under fasting and postprandial, respectively (p<0.05), representing an increase of 30%. Considering that under fasting conditions most of the vitamin A transported to the milk originates in the retinol binding protein (RBP), the postprandial increase in colostrum retinol suggests a different transport mechanism of retinol to maternal milk from that performed by RBP. This situation becomes more evident under supplementation conditions.

Avaliação da suplementação com vitamina E, na forma natural ou sintética, em mulheres no pós-parto imediato e sua concentração no colostro

The Vitamin E consists of eight chemically homologous forms, designated alpha, beta, gamma and delta tocopherols and tocotrienols. Biologically, the alpha-tocopherol (α-TOH) is the most important. Commercially, are found two types of α-TOH a natural (RRR-alpha-tocopherol) and another synthetic (all-rac-alpha-tocopherol). Both forms are absorbed in the intestine, the liver is a preference in favor of forms 2R, due to transfer protein α-TOH. It has higher affinity to these stereoisomers. Newborns are considered high risk for vitamin E deficiency, mainly premature, these have breast milk as a food source for maintenance of serum α-TOH. Clinical signs such as thrombocytosis, hemolytic anemia, retrolental fibroplasia, intraventricular hemorrhage, bronchopulmonary dysplasia and spinocerebellar degeneration can be found in case of a low intake of α-TOH. Thus, maternal supplementation on postpartum with α-TOH can be an efficient way to increase levels of vitamin E in breast milk and thus the consequently increase the supply of micronutrient for the newborn. However, most studies with vitamin E supplementation have been conducted in animals and little is known about the effect of maternal supplementation in humans, as well as on its efficiency to increase levels of α-TOH in human milk, depending on the shape natural or synthetic. The study included 109 women, divided into three groups: control without supplementation (GC) (n=36), supplemented with natural capsule (GNAT) (n=40) and the synthetic capsule (GSINT) (n=33). Blood samples were collected for determination of maternal nutritional status, and colostrums at initial contact and after 24 hours post-supplementation. Analyses were performed by High Performance Liquid Chromatography. Values of α-TOH in serum below 499.6mg/dL were considered deficient. We used the Kruskal-Wallis test and Tukey test to confirm the increase of alpha-tocopherol in milk and efficiency of administered capsules. Daily consumption of α-TOH was based on daily intake of 500 mL of colostrum by the newborn and compared with the nutritional requirement for children from 0 to 6 months of age, 4 mg / day. The mothers had mean concentration of serum α-TOH in 1016 ± 52, 1236 ± 51 and 1083 ± 61 mg / dL, in CG, GNAT and GSINT respectively. There were no women with deficiiency. The GC did not change the concentrations of α-TOH in colostrum. While women supplemented with natural and synthetic forms increased concentrations of α-TOH colostrum in 57.6% and 39%, respectively. By comparing supplemented groups, it was observed a significant difference (p=0.04), the natural capsule more efficient than the synthetic, approximately 49.6%. Individually, 21.1% of the women provided below 4mg/day of α-TOH, after supplementation for this index declined4.1%. Thus, maternal supplementation postpartum raised the levels of alpha-tocopherol in colostrum, and increased efficiency was observed with the natural form

Efeito da suplementação com retinol palmitato em codornas (Coturnix coturnx japonica) nos níveis de retinol na gema dos ovos

Vitamin A deficiency is a serious public health problem in developing countries, and it causes death and blindness among children in the developing countries. The fortification of food could be an important source of vitamins to control deficiency. 60 Coturnix coturnix japonica quails were used in a randomized design with duration of seven weeks. The birds were assigned into five treatments with four repetitions. The objective was to evaluate the influence of the supplementation with different levels of retinyl palmitate (2,000 IU, 4,000 IU, 8,000IU and 16,000 IU) in quails under the levels of retinyl in egg yolks. The method used to dose retinyl in yolks of quail eggs was High Performance Liquid Chromatography and the enzymatic method to quantify the cholesterol concentration. The weight and production of eggs was significantly modified by the supplementation with retinyl in the birds. The results showed a gradual increase in the incorporation of retinyl in the egg yolk as a response to the supplementation, reaching values 384% higher than the control values. By the end of the supplementations a significant reduction in the concentrations of retinyl in the eggs yolk was observed. The most lasting supplementations were with 8,000 IU and 16,000 IU which lasted for three weeks. The cholesterol content in eggs was not significantly modified. The consumption of one egg enriched with 16000UI of retinol palmitate in the present study, by day, would probably reach 10 and 7,3% of the daily recommendations of this micronutrient for children of 1 to 3 years of age, and for 4 to 8 years, respectively. The nutritional value of eggs, related to the vitamin A, can be improved by supplementation of quails

Influência da suplementação de retinol palmitato sobre os níveis de vitamina A no leite de puérperas saudáveis

The tendency towards reduction of serum retinol levels, an existing placental barrier and the increase of retinol demand, are factors that place puerperal and lactating women at risk for Vitamin A deficiency. This micronutrient is an essential component of vital processes such as differentiation, cellular proliferation, and apoptosis. The objective of this study is to evaluate the effect of palmitate retinol supplementation (100.000UI) upon the milk retinollevels in puerperal women at the Januário Cicco University Maternity Hospital. This intervention has been adopted by the Ministry of Health since 2002. The longitudinal experiment was conducted with 106 puerperal women (68 comprised the supplemented group and 38 the control group). The High Performance Liquid Chromatography (HPLC) method was used to dose the retinol of the milk and serum samples, and the creamtocrit method to determine the milk fat levels. The retinol means for the colostrums were 99.0 ± 64.4 ug/dL and 160.1 ± 94,4 ug/dl 6 hours afier supplementation; 68.9 ± 33.5 ug/dL for the transitional milk, and 30.6 ± 15.2 ug/dL for the mature milk of the supplemented group. Ali the difterences between means were statistically significant. The difterence between retinol means in the control group were also significant, with these being greater in the colostrum, 88.6 ± 62.1 ug/dL with 61.9 ± 30.1 ug/dl in the transition milk and 32.9 ±32.9 ± 17.6 ug/dL in the mature milk. No significant difference was observed in the retinol means of the three types ot milk in the supplemented group when compared to their respective means in the control group. The prevalence in serum (35.1 % and 81.1 % for the cutting point 20 ug/dL, respectively) and in milk (51.4%) revealed vitamin A deficiency as a public health problem. COlostrum, transition, and mature milk tats varied similarly in the supplemented group (1,92 ± 0,96; 3,25 ± 1,27 and 3,31 ± 1,36 grams) and in the control group (1,87 ± 1,14; 3,25 ± 1,31 and 3,36 ± 1,67 grams), with an observed difference between the colostrum/transition milk and the colostrum/mature milk fats. No difference was observed between the groups. The study showed that the 200.000UI supplementation was not sufficient to increase the milk retinol to the desired levels nor to meet the demands of the mothers with deprived hepatic reserves. It is suggested that another similar dose be offered within 30 days or less, and within 2 months post-partum, while continual/y monitoring for possible pregnancy

Efeitos da suplementação oral de zinco sobre o crescimento de crianças pré-púberes saudáveis e eutróficas

Introdução: o zinco é um importante micronutriente para numerosos processos bioquímicos em animais e humanos, desempenhando papel de destaque no crescimento e desenvolvimento. Em populações mundiais, a deficiência primária grave de zinco não é comum, embora, a deficiência leve seja bastante prevalente. Considerando que o zinco é essencial para a saúde humana e regula o sistema hipotálamo, hipófise, fígado e osso, buscamos averiguar os seus efeitos no eixo GH-IGF1-IGFBP3 agudamente, mediante administração intravenosa com o elemento zinco, e cronicamente, mediante suplementação oral com o elemento zinco, usando doses fisiológicas de 0.06537 mg Zn/kg (via intravenosa) e 10 mg Zn/dia (via oral). A inclusão de crianças pré-púberes aparentemente saudáveis e eutróficas sem deficiência de zinco é raro na literatura, pois grande parte das publicações foram reportadas em crianças apresentando deficiência de zinco. A metodologia aplicada foi absolutamente inovadora e original, tornando o estudo altamente relevante para a interface entre endocrinologia e nutrição. Objetivo: investigar os efeitos da suplementação oral e administração intravenosa com o elemento zinco sobre a secreção de GH, IGF1, IGFBP3, OCN, ALP, TRAP e PT em crianças aparentemente saudáveis e eutróficas sem deficiência de zinco. Métodos: o estudo foi conduzido durante um período de três meses, e caracterizado por ser randomizado controlado triplo cego. As crianças foram selecionadas por amostragem não probabilística de conveniência, provenientes de escolas públicas municipais, de ambos os gêneros, na faixa etária compreendida entre 8 e 9 anos de idade, divididas em grupo controle (20 crianças recebendo solução placebo contendo 10% de sorbitol) e grupo experimental (20 crianças suplementadas com o elemento zinco na forma de sulfato de zinco heptahidratado – ZnSO4.7H2O). As crianças foram submetidas à suplementação oral de zinco elementar (10 mg Zn/dia) e à administração intravenosa de zinco (0.06537 mg Zn/kg de peso corporal), na forma de ZnSO4.7H2O, cujas amostras sanguíneas foram coletadas em 0, 60, 120, 180 e 210 minutos. Foram realizadas avaliações antropométricas e dietéticas e dosagens bioquímicas e hormonais nas crianças estudadas. Resultados: após a suplementação oral, foi observado no grupo experimental (i) aumento significativo dos valores de ingestão de energia total, proteína e gordura total (p = 0.0007, p< 0.0001, p< 0.0001, respectivamente), (ii) aumento significativo do zinco sérico basal (p< 0.0001), aumento significativo das concentrações plasmáticas de fostatase alcalina (p = 0.0270), e (iv) correlação positiva com o IGF1, IGFBP3, OCN, comparando antes e após a suplementação (p = 0.0011, p< 0.0001, p< 0.0446, respectivamente). Durante a administração venosa de zinco, as concentrações plasmáticas de IGF1 e IGFBP3 aumentaram significativamente no grupo experimental (p = 0.0468, p < 0.0001, respectivamente). Em relação o cálculo da adequação aparente, segundo as DRI, para o cálcio, houve inadequação da dieta com 85% de confiabilidade dos dados; para o ferro, adequação da dieta, com 85% de confiabilidade dos dados. Para o zinco, adequação da dieta, com 50% de confiabilidade dos dados. Conclusões: a suplementação oral com o elemento zinco pode ter estimulado um aumento na ingestão de energia total, proteína e gordura total, assim como, nas concentrações basais de zinco sérico e nas concentrações plasmáticas de fosfatase alcalina. A administração intravenosa de zinco aumentou as concentrações séricas de zinco e as concentrações plasmáticas de GH, IGF1 e IGFBP3 no grupo experimental.

Avaliação da suplementação de vitamina E sobre a concentração de alfa-tocoferol no leite materno em mulheres com partos prematuros

The term vitamin E refers to a group of eight molecular compounds which differ in structure and bioavailability, and the RRR-alpha-tocopherol more biologically active form. The composition of vitamin E in breast milk undergoes variations during lactation, colostrum and milk richer in this micronutrient compared to transitional and mature milk. Newborns, especially premature infants are more susceptible to vitamin E deficiency and to prevent the damage caused by this deficiency has been proposed supplementation of neonates with this micronutrient, however, there is no consensus to carry out this intervention. Thus, maternal supplementation with RRRalpha-tocopherol in the postpartum period can be a good alternative to try to raise the alpha-tocopherol levels in breast milk and therefore provide the premature newborn adequate amounts of vitamin E. This study to evaluate the effect of supplementation with 400 UI acetate RRR-alpha-tocopherol in women with premature births, on the concentration of alpha-tocopherol in breast milk colostrum, transitional and mature. The study included 89 healthy adult women were enrolled in the control group (n = 51) and supplemented group (n = 38). Blood samples were collected and milk colostrum soon after birth (0h milk) twenty-four hours, new rate of colostrum milk was collected (24h milk). The transitional and mature milk were collected in seven days (7d milk) and thirty days (30d milk) after delivery, respectively. Supplementation in the supplemented group was held after the collection of blood and 0h milk. The alpha-tocopherol analyzes were performed by high-performance liquid chromatography. Serum levels of alpha-tocopherol less than 516 μg/dL were considered indicative of nutritional deficiency. The average concentration of alphatocopherol in the serum of the control group mothers was 1159.8 ± 292.4 μg/dL and the supplemented group was 1128.3 ± 407.2 μg/dL (p = 0.281). All women had nutritional status in vitamin E suitable. In both groups, it was observed that the concentration of vitamin E in colostrum milk was higher compared to transitional and mature milk. In the supplemented group, the concentration of alpha-tocopherol in the milk increased 60 % after supplementation, from 1339.3 ± 414.2 μg/dL (0h milk) to 2234.7 ± 997.3 μg/dL (24h milk). While the control group values in colostrum 0h and colostrum 24h were similar (p = 0.681). In the control group the follow-on milk alphatocopherol value was 875.3 ± 292.4 μg/dL and in the group supplemented 1352.8 ± 542.3 μg/dL, an increase of 35% in the supplemented group compared to control (p <0.001). In mature milk alpha-tocopherol concentrations between the control group (426.6 ± 187.5 μg/dL) and supplemented (416.4 ± 214.2 μg/dL) were similar (p = 0.853). Only 24h milk supplemented group answered the nutritional requirement of alpha-tocopherol (4 mg/day) of the newborn. These results show that the transport of this micronutrient for milk occurs in a controlled and limited way. Thus, the native vitamin E supplementation increases the concentration of alpha-tocopherol in colostrum and milk and transition does not influence the concentration in mature milk. Only the increase in colostrum milk was sufficient to meet the nutritional requirement of premature newborns.

Métodos de avaliação nutricional para a suplementação oral com zinco em crianças pré-púberes não deficientes em zinco

Background: Zinc is an essential nutrient that is required for numerous metabolic functions, and zinc deficiency results in growth retardation, cellmediated immune dysfunction, and cognitive impairment. Objective: This study evaluated nutritional assessment methods for zinc supplementation in prepubertal nonzinc- deficient children. Design: We performed a randomised, controlled, triple-blind study. The children were divided into a control group (10% sorbitol, n = 31) and an experimental group (10 mg Zn/day, n = 31) for 3 months. Anthropometric and dietary assessments as well as bioelectrical measurements were performed in all children. Results: Our study showed (1) an increased body mass index for age and an increased phase angle in the experimental group; (2) a positive correlation between nutritional assessment parameters in both groups; (3) increased soft tissue, and mainly fat-free mass, in the body composition of the experimental group, as determined using bioelectrical impedance vector analysis; (4) increased consumption of all nutrients, including zinc, in the experimental group; and (5) an increased serum zinc concentration in both groups (p < 0.0001). Conclusions: Given that a reference for body composition analysis does not exist for intervention studies, longitudinal studies are needed to investigate vector migration during zinc supplementation. These results reinforce the importance of employing multiple techniques to assess the nutritional status of populations.

The mothers had mean concentration of serum α-TOH in 1016 ± 52, 1236 ± 51 and 1083 ± 61 mg / dL, in CG, GNAT and GSINT respectively. There were no women with deficiiency. The GC did not change the concentrations of α-TOH in colostrum. While women supplemented with natural and synthetic forms increased concentrations of α-TOH colostrum in 57.6% and 39%, respectively. By comparing supplemented groups, it was observed a significant difference (p=0.04), the natural capsule more efficient than the synthetic, approximately 49.6%. Individually, 21.1% of the women provided below 4mg/day of α-TOH, after supplementation for this index declined4.1%.
