Structural differences of prebiotic oligosaccharides influence their capability to enhance iron absorption in deficient rats
2014
This study evaluates the influence of novel galacto-oligosaccharides derived from lactulose (GOS-Lu), kojibiose or 4′-galactosyl-kojibiose in hematological parameters of Fe homeostasis using Fe-deficient animals. Liver TfR-2, IL-6, NFκB and PPAR-γ expression (mRNA) were also determined by RT-qPCR analyses, and active hepcidin peptide production and short chain fatty acids by LC coupled to MS/MS or UV detection. Feeding animals with GOS-Lu or kojibiose together with FeCl3 increased hemoglobin (Hb) production (by 17%) and mean Hb concentration into erythrocytes relative to animals administered with FeCl3 alone (14.1% and 19.7%, respectively). Animals administered with prebiotics showed decrea…
Inulin-iron complexes: a potential treatment of iron deficiency anaemia.
2007
The aim of this work was that to synthesize macromolecular derivatives based on inulin able to complex iron and useful in the treatment of iron deficiency anaemia. Carboxylated or thiolated/carboxylated inulin derivatives were obtained by single or double step reactions, respectively. The first one was obtained by reaction of inulin (INU) with succinic anhydride (SA) alone obtaining INU-SA derivative; the second one was obtained by the reaction of INU with succinic anhydride and subsequent reaction of INU-SA with cysteine; both derivatives were treated with ferric chloride in order to obtain the INU-SA-Fe(III) and INU-SA-Cys-Fe(III) complexes. Both complexes showed an excellent biodegradabi…
Noninvasive Imaging Estimation of Myocardial Iron Repletion Following Administration of Intravenous Iron : The Myocardial- Trial
2020
Background Intravenous ferric carboxymaltose ( FCM ) improves symptoms, functional capacity, and quality of life in heart failure and iron deficiency. The mechanisms underlying these effects are not fully understood. The aim of this study was to examine changes in myocardial iron content after FCM administration in patients with heart failure and iron deficiency using cardiac magnetic resonance. Methods and Results Fifty‐three stable heart failure and iron deficiency patients were randomly assigned 1:1 to receive intravenous FCM or placebo in a multicenter, double‐blind study. T2* and T1 mapping cardiac magnetic resonance sequences, noninvasive surrogates of intramyocardial iron, were eval…
Changes in myocardial iron content following administration of intravenous iron (Myocardial‐IRON): Study design
2018
Treatment with intravenous ferric carboxymaltose (FCM) has been shown to improve symptoms, functional capacity, and quality of life in patients with heart failure and iron deficiency. However, the underlying mechanisms for these beneficial effects remain undetermined. The aim of this study is to quantify cardiac magnetic resonance changes in myocardial iron content after administration of intravenous FCM in patients with heart failure and iron deficiency and contrast them with parameters of heart failure severity. This is a multicenter, double-blind, randomized study. Fifty patients with stable symptomatic heart failure, left ventricular ejection fraction <50%, and iron deficiency will be r…

Obesity and iron deficiency anemia as risk factors for asymptomatic bacteriuria.
2013
Background: Few studies examined the risk factors of asymptomatic bacteriuria, showing contradictory results. Our study aimed to examine the association between different clinical and laboratory parameters and asymptomatic bacteriuria in internal medicine patients. Materials and methods: 330 consecutive hospitalized subjects, asymptomatic for urinary tract infections (UTIs), underwent to microscopic examination of urine specimens. 100 subjects were positive for microscopic bacteriuria and were recruited into the study. At the quantitative urine culture 31 subjects of study population were positive while 69 subjects were negative for bacteriuria. Results: The analysis of clinical characteris…
A New Potential Dietary Approach to Supply Micronutrients to Physically Active People through Consumption of Biofortified Vegetables
2022
Micronutrients are required in many reactions involved in physical activity and exercise. Most physically active people do not meet the body’s needs in terms of micronutrients through diet. The novelty of the present manuscript is the use of an innovative dietary approach to supply micronutrients to physically active people through biofortified food. Therefore, the key point of this study was to verify whether supplementation with biofortified vegetables—and specifically molybdenum (Mo)-enriched lettuce—in healthy volunteers affects essential regulators of body homeostasis and, specifically, hematological parameters, iron and lipid metabolism, and hepatic function. Twenty-…

Extreme thrombocytosis as a sign of coeliac disease in the elderly: case report
2002
Increase in the number of blood platelets to over 1 000 000/mm 3 in elderly patients is generally considered secondary to a myeloproliferative or neoplastic disease. To report the case of an elderly woman hospitalized for extreme thrombocytosis associated with severe anaemia, who was found to be suffering from coeliac disease. The patient, aged 83 years, was hospitalized presenting with fatigue. Laboratory tests showed microcytic hypochromic anaemia (haemoglobin 4 g/dl) and extreme thrombocytosis (platelet count 1 400 000/mm 3 ). Physical examination was normal, with the exception of marked thinness. There was no evidence of macroscopic bleeding from the gastrointestinal or genitourinary tr…
An association between plasma ferritin concentrations measured 48 h after delivery and postpartum depression.
2010
Abstract Context Iron deficiency is the most common nutritional problem experienced by childbearing women, and postpartum depression (PPD) is the most common psychiatric disorder seen during the first year after delivery. The possible link between iron deficiency and PPD is not clear. Objective To evaluate whether iron status 48 h after delivery was associated with PPD. Our hypothesis was that iron deficiency would be associated with PPD. Design This was a prospective cohort study of depression-free women studied in the postpartum period. Setting Women who give birth at obstetric units in several general hospitals in Spain. Participants A subsample of 729 women was included in the present s…
