Forty infants, 6 to 36 mo old, with iron-deficiency anemia (hemoglobin < 11 g/dL) were matched and assigned to two groups. One group received FeS0(4) and the other received ferrous bis-glycinate chelate at a dose of 5 mg of Fe daily per kilogram of body weight for 28 d. Both groups had significant hemoglobin increases (P < 0.001), but only the group treated with ferrous bis-glycinate chelate had significant increases (P < 0.005) in plasma ferritin. Apparent iron bioavailabilities were calculated at 26.7% for FeS0(4) and 90.9% for ferrous bis-glycinate chelate. Regression analysis indicated that absorption of both sources of iron were similarly regulated by the body according to changes in hemoglobin. We concluded that ferrous bis-glycinate chelate is the iron of choice for the treatment of infants with iron-deficiency anemia because of its high bioavailability and good regulation. 相似文献

The objective of this study was to test whether milk is an appropriate vehicle for fortification with ferrous bis-glycine chelate and whether it has any effect on milk's organoleptic properties. In addition, the study examined the children's acceptability and tolerance of the fortifying agent. One hundred thirty-one children aged 6-14 years (79 males and 52 females) from two dormitories of the Ministry of Social Welfare in Riyadh City, Saudi Arabia participated in this study. The results of this trial showed that milk fortified with this iron chelate has unaltered organoleptic properties and is well accepted by the children. Hemoglobin and serum ferritin levels were measured before and after consuming one liter of milk fortified with 30 mg ferrous bis-glycine chelate per liter (6 mg elemental iron per liter) per day, for a period of three months. The prevalence of anemia (Hb < 12 g/dL) significantly dropped from 25.3 to 5.0%, and 23.0 to 9.6%, among boys and girls respectively. The prevalence of low serum ferritin values among boys dropped from 8.8 to 5.9% and significantly from 21.1 to 12.1% among girls. No control group was included in this study. It is concluded that ferrous bis-glycine chelate in milk does not alter milk's organoleptic properties; furthermore, it improved hemoglobin and ferritin serum levels among anemic children, suggesting milk as an appropriate vehicle for fortification with this chelate. 相似文献

This review was elaborated in order to contribute to the planning of strategies for controlling iron deficiency anemia in developing countries. The need for intervention should be determined by the degree of iron deficiency in the individual group and knowledge of its effects on quality of life, morbidity, and mortality. The most frequent approach is to provide iron supplementation during pregnancy, lactation, and early childhood as a basic primary healthcare measure. Fortification and dietary modification are complementary approaches, and should be developed. 相似文献

OBJECTIVE: Iron deficiency anemia is caused by decreased production of red blood cells (RBCs) and is characterized by a reduction in either the hematocrit (Ht) or the concentration of hemoglobin (Hb). It is detected by blood iron status measures that are below population reference standards and also below the "usual or normal" levels for an individual. In some medicine practices, usually only hemoglobin and hematocrit are routinely measured with a full blood count, without measuring the indicators of iron status. Biochemical measures that are collected on single occasion are difficult to interpret in individuals, and normal ranges of hemoglobin and hematocrit do not necessarily confirm an iron deficiency condition, because they decrease only when severe iron depletion is present and are often unreliable or misleading. Thus, iron-depleted individuals can quickly develop iron deficiency if not detected early. METHODS: Information from hematological laboratory tests records on female patients at reproductive ages were collected and analysed. RESULTS: In this study, measurement of general test for anemia in some individuals revealed normal levels of RBCs count, Hb, Ht, mean corpuscular volume (MCV), mean cell hemoglobin concentration (MCHC), and cell morphology, whereas the levels of parameters of iron depletion and iron deficiency anemia such as serum iron and ferritin showed reduced values. The results indicate that individuals who are ordered cell blood count (CBC) measures alone without examining the indicators of iron status (Group C vs Group D) may not be correctly assessed with a definitive diagnosis and categorized as normal individuals. But in fact, they are susceptible to iron depletion and could develop iron deficiency anemia. CONCLUSIONS: In evaluation of iron deficiency status it is important that total CBC test be accompanied by the other tests of iron status to pinpoint true iron deficiency. Otherwise, many cases may be missed out and misdiagnosed as normal individuals. 相似文献

Commercial elemental iron powders (electrolytic and reduced iron), as well as heme iron supplements, were tested for efficacy in improving the iron status of women. In a randomized, double-blind trial, 51 women with moderate to low iron stores received daily for 12 wk: 1) placebo, 2) 5 mg iron as heme iron or 50 mg iron as 3) electrolytic iron, 4) reduced iron, or 5) FeSO(4). Treatments were provided in 2 capsules (heme carrier) and 3 wheat rolls (other iron sources). Differences in iron status, food nonheme iron absorption, and fecal properties were evaluated. Body iron, assessed from the serum transferrin receptor:ferritin ratio, increased significantly more in subjects administered FeSO(4) (127 +/- 29 mg; mean +/- SEM) and electrolytic (115 +/- 37 mg), but not the reduced (74 +/- 32 mg) or heme (65 +/- 26 mg) iron forms, compared with those given placebo (2 +/- 19 mg). Based on body iron determinations, retention of the added iron was estimated as 3.0, 2.7, 1.8, and 15.5%, in the 4 iron-treated groups, respectively. Iron treatments did not affect food iron absorption. The 50 mg/d iron treatments increased fecal iron and free radical-generating capacity in vitro, but did not affect fecal water cytotoxicity. In subjects administered FeSO(4), fecal water content was increased slightly but significantly more than in the placebo group. In conclusion, electrolytic iron was approximately 86% as efficacious as FeSO(4) for improving body iron, but the power of this study was insufficient to detect any efficacy of the reduced or heme iron within 12 wk. With modification, this methodology of testing higher levels of food fortification for several weeks in healthy women with low iron stores has the potential for economically assessing the efficiency of iron compounds to improve iron status. 相似文献

This cross-sectional study aimed to identify the social and biological determinants of anemia in children enrolled in the Brazilian Income Transfer Program (PBF). The study evaluated 446 children (69.1% of the total enrolled) ranging from 6 to 84 months of age, of whom 262 were receiving the income transfer (60.2% of the beneficiaries) and 184 were not (87.6% of the non-beneficiaries). Testing for anemia was performed with the Hemocue portable hemoglobinometer, and the cutoff points were set at 11.0 and 11.5 g/dL, according to age bracket. The data were analyzed using Poisson hierarchical regression with robust variance for multivariate analysis. There was no difference in the anemia prevalence rates between the beneficiary and non-beneficiary groups. Risk factors for anemia were low paternal schooling, cesarean birth, consumption of untreated water, stunting, and age less than 24 months. Prevalence of anemia in the group of non-beneficiary children under two years of age was significantly higher than in the beneficiary group in the same age bracket, suggesting the importance of the PBF income transfer for preventing anemia in children. 相似文献

The predictive value positive of serum iron studies and erythrocyte indices in differentiating between iron deficiency anemia and the anemia of chronic disease (ACD) were determined in 82 hospitalized patients with an iron-binding saturation of 15 percent or less. Iron deficiency, determined by serum ferritin of 20 ng/mL or less, was present in only 31 percent of patients with a serum iron level of 10 micrograms/dL or less; 39 percent of patients with a transferrin saturation of 5 percent or less, and 54 percent of patients with a total iron-binding capacity (TIBC) of 350 micrograms/dL or greater; conversely, iron deficiency was present in only 3 percent of patients with a TIBC of 250 micrograms/dL or less. Iron deficiency was present in 83 percent of patients with a mean corpuscular volume (MCV) of 75 microns3 or less, but only 2 percent of patients with an MCV of 86 microns3 or greater. It is concluded that the MCV has strong predictive value positive (and negative) when below (or above) the values just cited, but that serum iron studies do not have sufficient predictive value to justify their use in the routine differentiation between iron deficiency anemia and the ACD in hospitalized patients when no other cause for anemia is likely. 相似文献
