Iron Complexes with Antarctic Krill-Derived Peptides Show Superior Effectiveness to Their Original Protein-Iron Complexes in Mice with Iron Deficiency Anemia. Nutrients 2023; 15:nu15112510. [PMID: 37299473 DOI: 10.3390/nu15112510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 05/21/2023] [Accepted: 05/27/2023] [Indexed: 06/12/2023] Open
Abstract
Antarctic krill protein-iron complex and peptide-iron complex were acquired to investigate their iron bioavailability, expression of iron-regulated genes, and in vivo antioxidant capacity. Results indicated that the Antarctic krill peptide-iron complex significantly increased the hemoglobin (Hb), serum iron (SI), and iron contents in the liver and spleen in iron-deficiency anemia (IDA) mice (p < 0.05) compared with those of the Antarctic krill protein-iron complex. Despite the gene expressions of the divalent metal transporter 1(DMT1), the transferrin (Tf), and the transferrin receptor (TfR) being better regulated by both Antarctic krill peptide-iron complex and protein-iron complex, the relative iron bioavailability of the Antarctic krill peptide-iron complex group (152.53 ± 21.05%) was significantly higher than that of the protein-iron complex group (112.75 ± 9.60%) (p < 0.05). Moreover, Antarctic krill peptide-iron complex could enhance the antioxidant enzyme activities of superoxidase dismutase (SOD) and glutathione peroxidase (GSH-Px), reduce the malondialdehyde (MDA) level in IDA mice compared with the protein-iron complex, and reduce the cell damage caused by IDA. Therefore, these results indicated that Antarctic krill peptide-iron complex could be used as a highly efficient and multifunctional iron supplement.

Abstract
This study was performed to investigate the gene polymorphisms of the myeloperoxidase (MPO) enzyme and to determine whether MPO gene polymorphisms influence the response to iron therapy in pediatric patients with iron deficiency anemia (IDA). In this case-control study, 50 Turkish children with IDA and 50 healthy controls were enrolled. Three MPO gene alleles were selected for genotyping in the study: GG, AG, and AA. The relationships of alleles with IDA were analyzed and compared in patients and controls. Pretreatment and posttreatment laboratory parameters and gene polymorphisms were compared in the patient group. There was a significant difference between patients with IDA and controls regarding genotype frequencies of the AA, GG, and AG alleles (P=0.005). However, the AG allele was found to be associated with variations in hemoglobin, red blood cell, hematocrit, mean corpuscular volumes, and mean corpuscular Hb concentrations levels. The frequency of AA, GG, and AG alleles of the MPO gene was potentially associated with changes in iron metabolism and the AG allele led to variations in various hemogram parameters.

Abstract
(1) Background: Controversy exists regarding the relationship between anemia and Parkinson's disease (PD). This study aimed to evaluate the risk of PD related to anemia in the Korean population. (2) Methods: The Korean National Health Insurance Service-National Sample Cohort, which includes adults over 40 years of age, was assessed from 2002 to 2015. A total of 5844 PD patients were matched by age, sex, income, and region of residence with 23,376 control participants at a ratio of 1:4. The analyzed covariates included age, sex, blood pressure, fasting blood glucose, obesity, smoking status, and alcohol consumption. A multiple logistic regression analysis was conducted for case-control analyses. (3) Results: The adjusted odds ratio (OR) for the risk of PD associated with anemia was 1.09 after adjusting for potential confounders (95% confidence interval (CI) 1.01-1.18, p = 0.030). Among men younger than 70 years, the adjusted OR of PD was 1.34 (95% CI 1.13-1.60, p = 0.001). (4) Conclusions: Our findings suggest that anemia may increase the risk of PD, particularly in men younger than 70 years. Further research is required to elucidate the causal relationship between these two diseases.

Abstract
Restrictions on the cultivation and ingestion of fava beans were first reported as early as the fifth century BC. Not until the late 19th century were clinical descriptions of fava-induced disease reported and soon after characterised as “favism” in the early 20th century. It is now well known that favism as well as drug-induced haemolysis is caused by a deficiency of the glucose-6-phosphate dehydrogenase (G6PD) enzyme, one of the most common enzyme deficiency in humans. Interest about the interaction between G6PD deficiency and therapeutics has increased recently because mass treatment with oxidative 8-aminoquinolines is necessary for malaria elimination. Historically, assessments of haemolytic risk have focused on the clinical outcomes (e.g., haemolysis) associated with either a simplified phenotypic G6PD characterisation (deficient or normal) or an ill-fitting classification of G6PD genetic variants. It is increasingly apparent that detailed knowledge of both aspects is required for a complete understanding of haemolytic risk. While more attention has been devoted recently to better phenotypic characterisation of G6PD activity (including the development of new point-of care tests), the classification of G6PD variants should be revised to be clinically useful in malaria eliminating countries and in populations with prevalent G6PD deficiency. The scope of this work is to summarize available literature on drug-induced haemolysis among individuals with different G6PD variants and to highlight knowledge gaps that could be filled with further clinical and laboratory research.

Abstract
Chronic kidney disease is highly prevalent worldwide. The decline of renal function is associated with inadequate removal of a variety of uremic toxins that exert detrimental effects on cells functioning, thus affecting the cardiovascular system. The occurrence of cardiovascular aberrations in CKD is related to the impact of traditional risk factors and non-traditional CKD-associated risk factors, including anemia; inflammation; oxidative stress; the presence of some uremic toxins; and factors related to the type, frequency of dialysis and the composition of dialysis fluid. Cardiovascular diseases are the most frequent cause for the deaths of patients with all stages of renal failure. The kidney is one of the vital sources of antioxidant enzymes, therefore, the impairment of this organ is associated with decreased levels of these enzymes as well as increased levels of pro-oxidants. Uremic toxins have been shown to play a vital role in the onset of oxidative stress. Hemodialysis itself also enhances oxidative stress. Elevated oxidative stress has been demonstrated to be strictly related to kidney and cardiac damage as it aggravates kidney dysfunction and induces cardiac hypertrophy. Antioxidant therapies may prove to be beneficial since they can decrease oxidative stress, reduce uremic cardiovascular toxicity and improve survival.

A Genome-Wide Association Study Identifies Blood Disorder-Related Variants Influencing Hemoglobin A 1c With Implications for Glycemic Status in U.S. Hispanics/Latinos. Diabetes Care 2019; 42:1784-1791. [PMID: 31213470 PMCID: PMC6702612 DOI: 10.2337/dc19-0168] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2019] [Accepted: 05/24/2019] [Indexed: 02/03/2023]
Abstract
OBJECTIVE We aimed to identify hemoglobin A1c (HbA1c)-associated genetic variants and examine their implications for glycemic status evaluated by HbA1c in U.S. Hispanics/Latinos with diverse genetic ancestries. RESEARCH DESIGN AND METHODS We conducted a genome-wide association study (GWAS) of HbA1c in 9,636 U.S. Hispanics/Latinos without diabetes from the Hispanic Community Health Study/Study of Latinos, followed by a replication among 4,729 U.S. Hispanics/Latinos from three independent studies. RESULTS Our GWAS and replication analyses showed 10 previously known and novel loci associated with HbA1c at genome-wide significance levels (P < 5.0 × 10-8). In particular, two African ancestry-specific variants, HBB-rs334 and G6PD-rs1050828, which are causal mutations for sickle cell disease and G6PD deficiency, respectively, had ∼10 times larger effect sizes on HbA1c levels (β = -0.31% [-3.4 mmol/mol]) and -0.35% [-3.8 mmol/mol] per minor allele, respectively) compared with other HbA1c-associated variants (0.03-0.04% [0.3-0.4 mmol/mol] per allele). A novel Amerindian ancestry-specific variant, HBM-rs145546625, was associated with HbA1c and hematologic traits but not with fasting glucose. The prevalence of hyperglycemia (prediabetes and diabetes) defined using fasting glucose or oral glucose tolerance test 2-h glucose was similar between carriers of HBB-rs334 or G6PD-rs1050828 HbA1c-lowering alleles and noncarriers, whereas the prevalence of hyperglycemia defined using HbA1c was significantly lower in carriers than in noncarriers (12.2% vs. 28.4%, P < 0.001). After recalibration of the HbA1c level taking HBB-rs334 and G6PD-rs1050828 into account, the prevalence of hyperglycemia in carriers was similar to noncarriers (31.3% vs. 28.4%, P = 0.28). CONCLUSIONS This study in U.S. Hispanics/Latinos found several ancestry-specific alleles associated with HbA1c through erythrocyte-related rather than glycemic-related pathways. The potential influences of these nonglycemic-related variants need to be considered when the HbA1c test is performed.

Abstract
Background Iron-deficiency anemia (IDA) or iron deficiency (ID) is by far the most common form of disorder affecting the cognitive development, physical growth and school performance of children in developing countries including Nigeria. Objectives In the present study, we aimed to examine whether IDA or ID, or both are associated with oxidative stress or otherwise by assessing the perturbations in oxidative stress markers including malondialdehyde (MDA), catalase (CAT) and superoxide dismutase (SOD). Methods Here, a total of eighty-one IDA, ID, and healthy control subjects of twenty-seven replicates each, were recruited and investigated. Human serum MDA, CAT and SOD levels were quantitatively analyzed using Enzyme-Linked Immunosorbant Assay. Results Mean serum MDA levels of IDA (5.10 ± 2.35 mmol/L) and ID (4.05 ± 1.35 mmol/L) groups were found to perturb significantly (p < 0.05), being higher than those of control (3.30 ± 0.95 mmol/L) subjects. Similarly, mean serum MDA levels of IDA (5.10 ± 2.35 mmol/L) group was found to be significantly (p < 0.05) higher when compared with ID (4.05 ± 1.35 mmol/L) subjects. Conversely, mean serum CAT and SOD activities of IDA (8.35 ± 2.21 ng/mL and 340.70 ± 153.65 ng/mL) group were found to differ significantly (p < 0.05), and those of ID (9.40 ± 1.47 ng/mL and 435.00 ± 144.75 ng/mL) subjects were found to perturb slightly (p > 0.05), being lower than those of control (10.40 ± 4.31 ng/mL and 482.12 ± 258.37 ng/mL) subjects. Conclusions Taken together, the results of the present study showed that lipid peroxidation was dramatically increased in both IDA and ID subjects in hydroperoxide-superoxide-dependent manner; in contrast, enzymatic antioxidant capacity was drastically decreased in both IDA and ID groups as evidenced by biochemical markers.

Abstract
BACKGROUND/OBJECTIVES Propolis has a rich source of bioactive compounds and has renal and hepatic protective properties. The purpose of this study was to investigate the beneficial effect of hydro-ethanolic extract of propolis against paracetamol-induced liver damage and impairment of kidney function, as well as hematological changes in rats. MATERIALS AND METHODS Six groups of rats were used; the first group was served as a control; the second and third groups were treated by propolis extract at a dose of 50 and 100 mg/kg.B.WT. respectively; the fourth group was treated by paracetamol (200 mg/kg.B.WT.); the fifth group was treated by propolis (50 mg/kg.B.WT.) for eight days and then received similar dose of propolis for following seven days with paracetamol at a dose of 200 mg/kg.B.WT. daily for the seven days; and the sixth group was treated with propolis (100 mg/kg.B.WT.) for eight days and then received similar dose of propolis for following seven days with paracetamol at a dose of 200 mg/kg.B.WT. daily for the seven days. All the animals were treated for a period of 15 days. At the end of the experimental period, blood samples were collected for measurement of the liver enzymes, serum albumin, protein and creatinine, blood urea nitrogen, hematological parameters, and urine volume, protein and albumin. RESULTS Paracetamol over dose significantly lowered hemoglobin, serum total protein, albumin, and uric acid, while it significantly increased blood creatinine, blood urea nitrogen, alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase activities, white blood cells, and platelet count as compared to the control. However, these alterations were significantly attenuated by the use of propolis extract and the effect was dose dependent. Interestingly, propolis prevented paracetamol induced proteinuria, low hemoglobin and body weight loss. CONCLUSIONS Propolis significantly prevented paracetamol induced renal, hepatic and hematological toxicity and might be useful in the management of liver and renal diseases particularly proteinuria.

Abstract
Patients with chronic kidney disease (CKD) have significant cardiovascular morbidity and mortality as a result of risk factors such as left ventricular hypertrophy (LVH), oxidative stress, and inflammation. The presence of anaemia in CKD further increases the risk of LVH and oxidative stress, thereby magnifying the deleterious consequence in uraemic cardiomyopathy (UCM), and aggravating progression to failure and increasing the risk of sudden cardiac death. This short review highlights the specific cardio-renal oxidative stress in CKD and provides an understanding of the pathophysiology and impact of uraemic toxins, inflammation, and anaemia on oxidative stress.

Abstract
Sickle cell trait (SCT) is the benign condition of sickle cell disease. Often asymptomatic, the carriers of the sickle cell trait have hemorheological disturbances with increased oxidative stress compared to healthy subjects. These disturbances can lead to structural and functional changes in large vessels. The aim of the study was to measure arterial stiffness, an independent marker of subclinical atherosclerosis, SCT carriers compared to sickle cell anemia (SCA) subjects. Nine SCT carriers aged 32±9 years (7 men) were compared to 14 SCA subjects aged 29±9 years (2 men) and 22 control subjects aged 34±9 years (11 men) recruited by the National blood transfusion center (CNTS) in Dakar (Senegal). Arterial stiffness was assessed by measurement of the finger-toe pulse wave velocity (PWVft) using pOpmètre® (Axelife SAS-France). The cardiovascular risk (CVR) was assessed according to the Framingham Laurier score. The SCT carriers had a higher PWVft (m/s) than SCA subjects (8.2±2.2 vs 6.1±0.9m/s, P=0.004) but not different from that of healthy controls (8.2±2.2 vs 7.4±1.8m/s, P=0.33). Linear regression showed a positive relationship between PWVft and the pulse pressure (PP) (P˂0.001; r2=0.39; F=13.20). The results show that the SCT carriers have stiffer arteries than SCA subjects. Linear regressions adjusted for age, mean arterial pressure (MAP) and PP, showed that only age and PP were independently correlated with arterial stiffness in the entire population.

Abstract
The present study aims to investigate the protective effects of an orally administered Lachnum YM226 melanin-iron complex (LM-Fe) against iron deficiency anemia (IDA) in mice. The IDA mouse model was established by feeding mice with iron-deficient food. Different doses of LM-Fe were given to the anaemic mice via intragastric administration, with FeCl3 and FeSO4 used as positive controls. After the iron supplement administration, it was observed that LM-Fe could significantly improve the decreased haemoglobin (Hb) level, and normalize the serum iron (SI) level, total iron-binding capacity (TIBC) and serum ferritin (SF) of the anaemic mice in a dose-dependent manner. In addition, treatment with LM-Fe significantly increased the antioxidant enzyme activities of superoxidase dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) in plasma to normal or better. Furthermore, the levels of tumour necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and interleukin-6 (IL-6) were obviously decreased in the LM-Fe supplemented groups compared with the model group, while the level of interleukin-2 (IL-2) was significantly increased. In conclusion, LM-Fe was efficient at ameliorating the anemia symptoms, improving the activities of antioxidant enzymes and adjusting the immune dysfunction of anaemic mice. Thus, these results demonstrated that LM-Fe might be exploited as an efficient and multifunctional iron supplement.

Abstract
Iron deficiency is one of the most prominent mineral deficiencies around the world, which especially affects large population of women and children. Development of new technologies to combat iron deficiency is on high demand. Therefore, we developed alginate microcapsule with encapsulated iron that had better oral iron bioavailability. Microcapsules containing iron with varying ratios of sodium alginate ferric(III)-saccharide were prepared using emulsification method. In vitro studies with Caco-2 cells suggested that newly synthesized microemulsions had better iron bioavailability as compared to commercially available iron dextran formulations. Ferrozine in vitro assay showed that alginate-encapsulated ferric galactose microemulsion (AFGM) had highest iron bioavailability in comparison to other four ferric saccharate microemulsions, namely AFGlM, AFMM, AFSM, and AFFM synthesized in our laboratory. Mice studies also suggested that AFGM showed higher iron absorption as indicated by increased serum iron, hemoglobin, and other hematopoietic measures with almost no toxicity at tested doses. Development of iron-loaded microemulsions leads to higher bioavailability of iron and can provide alternative strategies to treat iron deficiency.

Abstract
The aim of this study was to evaluate the oxidant profile and iron metabolism in serum of dogs infected by Ehrlichia canis. Banked sera samples of dogs were divided into two groups: negative control (n = 17) and infected by E. canis on acute (n = 24), and subclinical (n = 18) phases of the disease. The eritrogram, leucogram, and platelet counts were evaluate as well as iron, ferritin, and transferrin levels, latent iron binding capacity (LIBC), and transferrin saturation index (TSI) concentration. In addition, the advanced oxidation protein products (AOPP) and ferric reducing ability of plasma (FRAP) in sera were also analyzed. Blood samples were examined for the presence of E. canis by PCR techniques. History and clinical signals were recorded for each dog. During the acute phase of the disease, infected animals showed thrombocytopenia and anemia when compared to healthy animals (P < 0.05) as a consequence of lower iron levels. Ferritin and transferrin levels were higher in both phases (acute and subclinical) of the disease. The AOPP and FRAP levels increased in infected animals on the acute phase; however, the opposite occurred in the subclinical phase. We concluded that dogs naturally infected by E. canis showed changes in the iron metabolism and developed an oxidant status in consequence of disease pathophysiology.

Erythrocyte Catalase Activity in More Frequent Microcytic Hypochromic Anemia: Beta-Thalassemia Trait and Iron Deficiency Anemia. Adv Hematol 2015; 2015:343571. [PMID: 26527217 PMCID: PMC4615862 DOI: 10.1155/2015/343571] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2015] [Revised: 09/10/2015] [Accepted: 09/16/2015] [Indexed: 01/02/2023] Open
Abstract
Most common microcytic hypochromic anemias are iron deficiency anemia (IDA) and β-thalassemia trait (BTT), in which oxidative stress (OxS) has an essential role. Catalase causes detoxification of H2O2 in cells, and it is an indispensable antioxidant enzyme. The study was designed to measure erythrocyte catalase activity (ECAT) in patients with IDA (10) or BTT (21), to relate it with thalassemia mutation type (β0 or β+) and to compare it with normal subjects (67). Ninety-eight individuals were analyzed since September 2013 to June 2014 in Tucumán, Argentina. Total blood count, hemoglobin electrophoresis at alkaline pH, HbA2, catalase, and iron status were performed. β-thalassemic mutations were determined by real-time PCR. Normal range for ECAT was 70,0–130,0 MU/L. ECAT was increased in 14% (3/21) of BTT subjects and decreased in 40% (4/10) of those with IDA. No significant difference (p = 0,245) was shown between normal and BTT groups, while between IDA and normal groups the difference was proved to be significant (p = 0,000). In β0 and β+ groups, no significant difference (p = 0,359) was observed. An altered ECAT was detected in IDA and BTT. These results will help to clarify how the catalase activity works in these anemia types.

Abstract
BACKGROUND Iron deficiency anemia (IDA) is the most common nutritional deficiency in the world. The aim of our study was to evaluate and compare renal functional and structural integrity in 50 infants with IDA and 50 healthy controls and to assess the relation between IDA and oxidative stress and response to iron therapy. METHODS This was a prospective study in which peripheral blood samples were collected from all study subjects and the following laboratory investigations performed: serum iron profile, urinary microalbumin, urinary leucine aminopeptidase (LAP), fractional excretion of sodium (FeNa), serum total antioxidant capacity (TAC), serum malondialdehyde (MDA), serum and urinary trace elements (iron, copper, zinc, calcium and magnesium). All patients received oral iron therapy and were followed-up for 3 months. RESULTS The levels of baseline urinary markers were higher among the patients with IDA than among the controls (p < 0.05). Patients had a lower pre-therapy TAC and lower serum zinc and magnesium levels than controls as well as higher MDA and serum copper levels (p < 0.05). MDA level was positively correlated to microalbumin and LAP level (p < 0.05). Urinary LAP concentration was positively correlated to urinary trace element concentrations (p < 0.05). A significant decrease in microalbumin, LAP, FeNa, and urinary trace elements was observed post-iron therapy while hemoglobin and ferritin levels were increased (p < 0.05). CONCLUSION Among the study subjects, IDA had an adverse influence on renal functional and structural integrity which could be reversed with iron therapy. Oxidative stress played an important role in the pathogenesis of renal injury in IDA.

Abstract
The aim of this study was to assess the effects of iron supplementation on oxidative stress and on the activity of the adenosine deaminase (ADA) in rats experimentally infected by Trypanosoma evansi. For this purpose, 20 rats were divided into four experimental groups with five animals each as follows: groups A and B were composed by healthy animals, while animals from groups C and D were infected by T. evansi. Additionally, groups B and D received two subcutaneous doses of iron (60 mg kg(-1)) within an interval of 5 days. Blood samples were drawn on day 8 post infection in order to assess hematological and biochemical variables. Among the main results are: (1) animals from group C showed reduced erythrogram (with tendency to anemia); however the same results were not observed for group D; this might be a direct effect of free iron on trypanosomes which helped to reduce the parasitemia and the damage to erythrocytes caused by the infection; (2) iron supplementation was able to reduce NOx levels by inhibiting iNOS, and thus, providing an antioxidant action and, indirectly, reducing the ALT levels in groups Band D; (3) increase FRAP levels in group D; (4) reduce ADA activity in serum and erythrocytes in group C; however, this supplementation (5) increased the protein oxidation in groups B and D, as well as group C (positive control). Therefore, iron showed antioxidant and oxidant effects on animals that received supplementation; and it maintained the activity of E-ADA stable in infected/supplemented animals.

Abstract
Glucosamine (GlcN) is an important precursor in the biochemical synthesis of glycosylated proteins and lipids in human body. It gains importance because of its contribution to human health and its multiple biological and therapeutic effects. In this study, the in vitro oxidative hemolysis of rat erythrocyte was used as a model to study the potential protective effect of glucosamine hydrochloride against free radical-induced damage of biological membranes. Glucosamine hydrochloride exhibited dose-dependent DPPH antioxidant activity. Oxidative hemolysis and lipid/protein peroxidation of erythrocytes induced by a water-soluble free radical initiator 2,2'-azobis (2-amidinopropane) dihydrochloride (AAPH) were significantly suppressed by GlcN in a time and dose dependent manner. GlcN also prevented the depletion of cytosolic antioxidant glutathione (GSH) in erythrocytes. These results indicated that glucosamine hydrochloride efficiently protected erythrocytes against free radicals and it could be recommended as a pharmaceutical supplement to alleviate oxidative stress.

Abstract
BACKGROUND Oxidative stress is an imbalance between the reactive oxygen species and antioxidant system. In this study, total oxidative stress (TOS) and total antioxidant capacity (TAC) were investigated with a new and practical method in childhood iron-deficiency anemia. METHOD During the study period 80 children between 6 and 60 months were enrolled; 40 children (study group) had iron-deficiency anemia, and 40 children (control group) were healthy. Complete blood count, serum iron, iron-binding capacity, ferritin levels, TOS, and TAC were evaluated. Children diagnosed iron-deficiency anemia were treated with oral ferric iron. After 2 months of the treatment, blood tests of the study groups were repeated to check the challenge. RESULTS TAC was similar between both groups (1.55 ± 0.26 in control group 1.53 ± 0.19 mmol Trolox Eq./l). Additionally, TOS was significantly higher in iron-deficiency anemia group before treatment with iron (24.3 ± 18.5, in controls groups 14.4 ± 7.1 mmol Trolox Eq./l). We have shown that TAC did not change (before treatment 1.55 ± 0.26, after treatment 1.54 ± 0.26 mmol Trolox Eq./l) although TOS decreased significantly after the treatment of iron-deficiency anemia (before treatment 24.3 ± 18.5, after treatment 12.4 ± 6.9 mmol Trolox Eq./l). We did not find any correlation between hemoglobin, serum iron, iron-binding capacity, ferritin levels, and TOS or TAC among iron-deficiency anemia patients. CONCLUSION As a result of this study, oxidative stress increases in children with iron-deficiency anemia and this increase can be returned to normal levels by treatment.

Abstract
It is common knowledge that thalassemic patients are under significant oxidative stress. Chronic hemolysis, frequent blood transfusion, and increased intestinal absorption of iron are the main factors that result in iron overload with its subsequent pathophysiologic complications. Iron overload frequently associates with the generation of redox-reactive labile iron, which in turn promotes the production of other reactive oxygen species (ROS). If not neutralized, uncontrolled production of ROS often leads to damage of various intra- and extracellular components such as DNA, proteins, lipids, and small antioxidant molecules among others. A number of endogenous and exogenous defense mechanisms can neutralize and counteract the damaging effects of labile iron and the reactive substances associated with it. Endogenous antioxidant enzymes, such as superoxide dismutase, catalase, glutathione peroxidase, and ferroxidase, may directly or sequentially terminate the activities of ROS. Nonenzymatic endogenous defense mechanisms include metal binding proteins (ceruloplasmin, haptoglobin, albumin, and others) and endogenously produced free radical scavengers (glutathione (GSH), ubiquinols, and uric acid). Exogenous agents that are known to function as antioxidants (vitamins C and E, selenium, and zinc) are mostly diet-derived. In this review, we explore recent findings related to various antioxidative mechanisms operative in thalassemic patients with special emphasis on protein antioxidants.

Abstract
Despite Fe deficiency and overload having been widely studied, no studies are available about the influence of milk consumption on antioxidant defence and lipid peroxidation during the course of these highly prevalent cases. The objective of the present study was to assess the influence of cow or goat milk-based diets, either with normal or Fe-overload, on antioxidant defence and lipid peroxidation in the liver, brain and erythrocytes of control and anaemic rats after chronic Fe repletion. Weanling male rats were randomly divided into two groups: a control group receiving a normal-Fe diet (45 mg/kg) and an anaemic group receiving a low-Fe diet (5 mg/kg) for 40 d. Control and anaemic rats were fed goat or cow milk-based diets, either with normal Fe or Fe-overload (450 mg/kg), for 30 or 50 d. Fe-deficiency anaemia did not have any effect on antioxidant enzymes or lipid peroxidation in the organs studied. During chronic Fe repletion, superoxide dismutase (SOD) activity was higher in the group of animals fed the cow milk diet compared with the group consuming goat milk. The slight modification of catalase and glutathione peroxidise activities in animals fed the cow milk-based diet reveals that these enzymes are unable to neutralise and scavenge the high generation of free radicals produced. The animals fed the cow milk diet showed higher rates of lipid peroxidation compared with those receiving the goat milk diet, which directly correlated with the increase in SOD activity. It was concluded that goat milk has positive effects on antioxidant defence, even in a situation of Fe overload, limiting lipid peroxidation.

Abstract
AbstractThe antioxidative activity of the extract from Conyza canadensis in plasma treated with peroxynitrite (ONOO−) (0.1 mM) was studied. C. canadensis is known to possess a broad set of pharmacological effects because of content of various antioxidants, antiplatelet and anticoagulant compounds. The aim of our study was to assess if this extract protects plasma proteins against oxidative/nitrative damages induced by ONOO−. The plasma components are continuously exposed to reactive oxygen/nitrogen species action. Peroxynitrite evokes oxidative stress and induces undesirable effects in biological systems and causes damage to biomolecules. The extract from Conyza (50–2500 mg/ml) caused a dose-dependent reduction of protein nitration by 90%. The oxidation of plasma proteins was diminished by about 75%. ONOO− oxidized the plasma thiol groups and this process was inhibited by tested extract. The level of reduced protein thiols was increased thrice at the lowest concentration of extract (50 mg/ml). The highest concentration of extract decreased twice the level of protein thiols in reduced forms and increased the homocysteine level about 4.5 times. The obtained results demonstrated that the extract from Conyza possesses antioxidative properties in vitro, protects plasma proteins against toxicity induced by peroxynitrite and has modulating effects on thiol/disulfide redox status.

Leukocyte DNA damage in children with iron deficiency anemia: effect of iron supplementation. Eur J Pediatr 2010; 169:951-6. [PMID: 20169450 DOI: 10.1007/s00431-010-1147-1] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2009] [Accepted: 01/18/2010] [Indexed: 10/19/2022]
Abstract
Iron deficiency is frequently associated with anemia. Iron is a transition-metal ion, and it can induce free radical formation, which leads to formation of various lesions in DNA, proteins, and lipids. The aim of this study was to investigate baseline oxidative DNA damage and to clarify the role of the administration of a therapeutic dose of iron on DNA oxidation in children with iron deficiency anemia (IDA). Twenty-seven children with IDA and 20 healthy children were enrolled in the study. Leukocyte DNA damage (strand breaks and Fpg-sensitive sites) was assessed using comet assay before and after 12 weeks of daily iron administration. Before the iron administration, the frequency of DNA strand breaks in the children with IDA was found to be lower than those in the control group (P < 0.05), but there was not a significant difference for frequency of Fpg-sensitive sites. After 12 weeks of iron administration, the frequency of both DNA strand breaks and Fpg-sensitive sites were found to be increased (P < 0.01). No significant association was determined between DNA damage parameters and hemoglobin, hematocrit, serum iron, total iron binding capacity, and ferritin. In conclusion, basal level of DNA strand breaks is at a low level in children with IDA. After iron administration, DNA strand breaks and Fpg-sensitive sites, which represent oxidatively damaged DNA, increased. However, this increase was unrelated to serum level of iron and ferritin.

Abstract
AIM Prolidase is a specific imidodipeptidase involved in collagen degradation. The increase in the enzyme activity is believed to be correlated with the increased intensity of collagen degradation. The study aimed to evaluate the relationship between prolidase activity and oxidative status in patients with thalassemia major. METHODS Comparison was made between 87 patients diagnosed with thalassemia major and 33 healthy children of similar age and gender. Mean age of the subjects was 7.5+/-4.3 years in the group of patients with thalassemia major and 8.9+/-3.1 years in the control group. Serum prolidase activity was measured spectrophotometrically. Oxidative status was determined using total oxidant status (TOS), total antioxidant capacity (TAC), and oxidative stress index (OSI) measurement. RESULTS Prolidase activity was significantly increased in patients with thalassemia major (53.7+/-8.7 U/l) compared to the control group (49.2+/-7.2 U/l, P<0.001). TOS was significantly increased in the patient group (5.31+/-3.14 mmol H2O2 equiv./l) compared to the control group (3.49+/-2.98 mumol H2O2 equiv./l) and the OSI was also significantly increased in the patient group (3.86+/-3.28 arbitrary unit) compared to the control group (2.53+/-2.70 arbitrary unit) (P<0.0001 and P<0.001, respectively), while there were no significant differences between the patient (1.61+/-0.30 mumol Trolox equiv./l) and control (1.64+/-0.33 mumol Trolox equiv./l) groups with respect to TAC. CONCLUSION Significant increases in prolidase activity in patients with thalassemia major may constitute a key parameter in demonstrating a disorder of the collagen metabolism.

Abstract
Oxidative stress is an imbalance between free radicals and antioxidant molecules that can play an important role in the pathogenesis of iron-deficiency anemia (IDA). The aim of this study was to investigate oxidative status in patients with IDA and alteration of oxidative status after iron treatment. Thirty-three female patients with IDA and 25 healthy controls were included in this study. Oxidant and total antioxidant capacity were determined using free oxygen radicals test and free oxygen radicals defence (Form CR 3000, Callegari, Parma, Italy). Catalase activity was measured by spectrophotometer using a commercially available kit (Bioxytech Catalase-520, OxisResearch, Portland, OR). Oxidant activity in patients with IDA was significantly higher than controls (P<0.05), while total antioxidant and catalase activity were significantly lower (P<0.05). After treatment, oxidant, antioxidant, and catalase activity reached the levels of the control group, and no significant differences were observed among groups (P>0.05). In conclusion, our data indicate that blood reactive oxygen species was lower and total antioxidant and catalase activity were higher after rather than before treatment in patients with IDA. The results of our study support the higher oxidative stress hypothesis in IDA; however, due to the limited number of cases included, more studies may be required to confirm the results.

Abstract
We propose that oxidative damage may play a role in the pathogenesis of iron deficiency anaemia (IDA). Participants were selected from Basic Attention Ambulatory from North of Rio Grande do Sul, Brazil. All subjects were older than 65 years - 17 patients with IDA and primary hypertension and 18 patients with primary hypertension (control group) were included in the present study. We measured antioxidant defenses including superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and total glutathione (GSH) by spectrophotometric assays. We also determined protein oxidative damage in haemolysate and plasma by carbonyl assay. We characterized the lipid peroxidation by malondialdehyde (MDA) accumulation. The results show that IDA patients had significantly higher CAT and SOD levels than controls. GPx activity was not different between the groups. Oxidative protein damage was noted in the plasma but not in the haemolysate. A significantly enhanced production of MDA was observed in the serum of IDA patients, as an indication of increased level of auto-oxidizable lipids under oxidative stress. These results support the idea that patients with IDA are subjected to chronic oxidative stress. Therefore it is important that IDA in older persons receives adequate attention in clinical practice and is not considered simply a part of normal aging.

Abstract
PURPOSE The aim of this study was to study paraoxonase and arylesterase activities along with oxidative status parameters, and to find out whether there is any increased susceptibility to atherogenesis, which might be reflected with increased oxidative stress and decreased serum paraoxonase/arylesterase activity in beta-thalassemia major (BTM) patients. PATIENTS AND METHODS Eighty-seven patients with BTM and 33 healthy individuals were enrolled in the study. RESULTS Paraoxonase and arylesterase activities were significantly lower in BTM patients than controls (for all P<0.0001), whereas total oxidant status, total peroxide concentration levels, and oxidative stress index were significantly higher (P<0.0001, <0.0001, and <0.001, respectively). Correlations were found between serum iron and ferritin and levels of total oxidant status in BTM patients. Significant correlation was found with serum total peroxide concentration levels and paraoxonase and arylesterase activities in patients with BTM. CONCLUSIONS It was seen that oxidative stress increases, while serum paraoxonase activity is decreased in BTM patients. Decrease in paraoxonase activity seems to be associated with both the degree of oxidative stress and anemia. BTM patients may be more prone to development of atherogenesis because of low serum paraoxonase/arylesterase activity.

Abstract
Iron Deficiency anemia ranks 9(th) among 26 diseases with highest burden. Asia bears 71% of this global burden. Adverse maternal and birth outcome associated with hemoglobin status renders the issue worth attention. Indian scenario has worsened over the period despite continuous international and national efforts. This indicates some lacunae in the approach and strategies applied. Various reports state that even with maximum effort to increase outreach and monitoring for adherence to Iron schedule, consumer's compliance remains abysmally low. Recent studies has pointed out biological basis of side effects (gastrointestinal complains and systemic events) as raised oxidative stress for which iron is the key catalyst. Up till now the only target of research has been to raise hemoglobin of pregnant women above 11gm/dl. With the reports of pregnancy specific morbidities i.e. hemorrhage and septicemia with low hemoglobin, eclampsia, small for gestation age, gestational diabetes with higher ranges of hemoglobin, alarm is raised to define optimum range. Use of oxidative stress as biochemical marker with different doses and schedules has been defined because India lack information for its own population upon oxidative stress status when iron is supplemented as per current guidelines. Studies done in India and abroad have defined that too much and too less, both may raise oxidative stress and studies of this sort may provide biochemical scale for optimization. This review therefore has evaluated currently available Indian research and reports to understand the need of future research area. Important findings from other countries have been incorporated for comparison.

Abstract
The risk of oral cavity cancer was determined in relation to serological levels of iron; vitamins A, B2, C, E; zinc; thiamin; and glutathione (GSH). The study included 65 hospitalized patients with oral cancer and 85 matched controls. In comparing the highest to the lowest tertiles, the risk was odds ratio (OR) = 0.3 [95% confidence interval (CI) = 0.1-0.6] for iron; 3.2 (95% CI = 1.3-8.1) for total iron binding capacity (TIBC), which measures the concentration of the iron delivery protein transferrin; and 0.4 (95% CI = 0.2-0.9) for transferrin saturation (iron/TIBC x 100). These associations were stronger in never smokers than in ever smokers. The risk associated with the iron storage protein ferritin was significantly elevated, but this association could reflect disease-related inflammation or comorbidity. The OR for GSH was 0.4 (95% CI = 0.1-0.9), and the OR for GSH reductase activity coefficient (indicative of riboflavin deficiency) was 1.6 (95% CI = 1.3-3.7). These findings suggest that mild iron deficiency and low GSH levels, which are associated with increased oxidative stress, increase the risk of oral cavity cancer.

Abstract
The objectives of this study were to determine the antioxidant activity of fruits containing polyphenolics, namely anthocyanins, and their capacity to reduced Fe (III) to Fe (II) under simulated gastrointestinal conditions. The antioxidant capacity of fruits against prooxidant iron was determined using an in vitro assay. All the fruits exhibited variable antioxidant activity to iron in comparison to the control, both in the presence and absence of digestive enzymes and bile salts. For the fruits containing anthocyanins it was possible to obtain a positive correlation between total ferrous iron and anthocyanins content. There are strong negative correlations between phenolic compounds and dialyzable ferrous iron.

Abstract
The ionic mechanisms and cytoprotective activities of 4-piperidinomethyl-2-isopropyl-5-methylphenol (THPI), an analogue of thymol, were investigated in HL-60 granulocytes and in human erythrocytes, respectively. THPI inhibited K+ outward current (I(K)) in a concentration-dependent manner in HL-60 leukocytes, with an IC50 value of 4 microM. Neither iberiotoxin (200 nM) nor paxilline (1 microM) suppressed the amplitude of I(K), whereas clotrimazole (5 microM) significantly inhibited it. In the inside-out configuration of single channel recordings, application of THPI (5 microM) into the bath medium did not alter the single-channel conductance of intermediate-conductance Ca2+-activated K+ (IK(Ca)) channels (i.e K(Ca)3.1 channels), but it suppressed the channel activity significantly. THPI-induced inhibition of IK(Ca) channels was reversed by a further application of 1-ethyl-2-benzimidazolinone (10 microM). THPI-induced reduction in IK(Ca)-channel activity in these cells was primarily due to a decrease in mean open time. These results provide direct evidence that THPI is capable of suppressing the activity of IK(Ca) channels in HL-60 cells. The antioxidant action of THPI also revealed a beneficial cytoprotective effect against mitomycin C-mediated haemolytic effect in human erythrocytes. The results of this study suggest that blockade of IK(Ca) channels and the membrane-protecting activity of THPI would combine to have beneficial effects in lessening the severity of haemolytic crisis and reducing anaemia in sickle cell disease.

Abstract
OBJECTIVES Paraoxonase-1 (PON1) deficiency is related to increased susceptibility to low density lipoprotein oxidation and development of atherosclerosis. The aim of this study was to investigate paraoxonase and arylesterase activities along with oxidative status parameters, and to find out if there is any increased susceptibility to atherogenesis, which might be reflected with increased oxidative stress and decreased serum PON1 activity in beta-thalassemia minor (BTM) subjects. DESIGN AND METHODS Thirty-two subjects with BTM and 28 healthy subjects as control were enrolled in the study. Serum paraoxonase and arylesterase activities, lipid hydroperoxide (LOOH) levels, total antioxidant capacity (TAC), total oxidant status (TOS) and oxidative stress index (OSI) were determined. RESULTS Serum TAC, paraoxonase and arylesterase activities were significantly lower in BTM subjects than controls (for all p<0.001), while TOS, LOOH levels and OSI were significantly higher (p<0.001, p<0.05 and p<0.001; respectively). In BTM subjects, OSI, TOS, LOOH levels and TAC were significantly correlated with serum paraoxonase (r=-0.245, p<0.05; r=-0.231, p<0.05; r=-0.264, p<0.05 and, r=0.342, p<0.05, respectively) and arylesterase activities (r=-0.332, p<0.05, r=-0.308, p<0.05; r=-0.320, p<0.05 and r=0.443, p<0.05). Additionally, hemoglobin level was also correlated with serum paraoxonase (r=0.501, p<0.001) and arylesterase activities (r=0.501, p<0.001), TAC (r=0.402, p<0.05), TOS (r=-0.274, p<0.05) and OSI (r=-0.352, p<0.05). CONCLUSIONS Oxidative stress is increased, while serum PON1 activity is decreased in BTM subjects. Decrease in PON1 activity seems to be associated with both the degree of oxidative stress and anemia. BTM subjects may be more prone to development of atherogenesis due to low serum PON1 activity.

Abstract
Membrane lipid and protein composition was compared in erythrocytes from iron deficiency anemia (IDA) and heterozygous beta thalassemia patients. The study was planned to correlate the influence of iron deficiency with the intrinsic defect of the heterozygous condition on the membrane structural integrity as well as to investigate whether there are differences in membrane changes between the two conditions. Results indicate high levels of saturated fatty acids and low unsaturated fatty acids in both disorders although arachidonic acid and the unsaturation index were lower in heterozygous thalassemia than IDA. Nevertheless, neither of the conditions provoked any alterations in membrane protein or glycophorin suggesting alterations in the lipid moiety only. Present findings indicate that irrespective to the etiology, both, iron deficiency and the heterozygous condition show a common pattern of lipid derangement, which may in turn result in increased membrane rigidity and decreased cellular deformability.

Abstract
Oxidant stress has been shown to play an important role in the pathogenesis of iron deficiency anemia. The aim of this study was to investigate the association between lymphocyte DNA damage, total antioxidant capacity and the degree of anemia in patients with iron deficiency anemia. Twenty-two female with iron deficiency anemia and 22 healthy females were enrolled in the study. Peripheral DNA damage was assessed using alkaline comet assay and plasma total antioxidant capacity was determined using an automated measurement method. Lymphocyte DNA damage of patients with iron deficiency anemia was significantly higher than controls (p<0.05), while total antioxidant capacity was significantly lower (p<0.001). While there was a positive correlation between total antioxidant capacity and hemoglobin levels (r=0.706, p<0.001), both total antioxidant capacity and hemoglobin levels were negatively correlated with DNA damage (r=-0.330, p<0.05 and r=-0.323, p<0.05, respectively). In conclusion, both oxidative stress and DNA damage are increased in IDA patients. Increased oxidative stress seems as an important factor that inducing DNA damage in those IDA patients. The relationships of oxidative stress and DNA damage with the severity of anemia suggest that both oxidative stress and DNA damage may, in part, have a role in the pathogenesis of IDA.

Abstract
Bidens pilosa (B. pilosa) is well known in Taiwan as a traditional Chinese medicine. The purpose of this study was to evaluate the ability of both the ethanol (EtOH) and ethylacetate/ethanol (EA/EtOH) extracts from the whole B. pilosa plant, to protect normal human erythrocytes against oxidative damage in vitro. It was determined that the oxidative hemolysis and lipid/protein peroxidation of erythrocytes induced by the aqueous peroxyl radical [2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH)] were suppressed by both EtOH (50-150 microg/ml) and EA/EtOH (25-75 microg/ml) extracts of B. pilosa in concentration- and time-dependent manners. B. pilosa extracts also prevented the decline of superoxide dismutase (SOD) activity and the depletion of cytosolic glutathione (GSH) and ATP in erythrocytes. These results imply that B. pilosa may have protective antioxidant properties.

Abstract
Exposure of erythrocytes to osmotic shock, oxidative stress, and energy depletion activates Cl--sensitive and Ca2+-permeable cation channels. Subsequent Ca2+ entry triggers eryptosis, characterized by erythrocyte shrinkage, membrane blebbing, and phosphatidylserine exposure all features typical for apoptotic death of nucleated cells. Erythrocytes exposing phosphatidylserine are recognized, bound, engulfed, and degraded by macrophages. Eryptosis thus fosters clearance of affected erythrocytes from circulating blood. Iron deficiency leads to anemia, in part by decreasing erythrocyte life span. In this study, phosphatidylserine exposure, cell size, and cytosolic Ca2+ were measured by FACS analysis of annexin-V binding, forward scatter, and Fluo-3 fluorescence, respectively. Erythrocytes from mice on control diet were compared with erythrocytes from mice exposed 10 weeks to iron-deficient diet. Iron deficiency significantly (P<0.001) enhanced erythrocyte annexin-V binding (from 2.4 to 3.7%), decreased forward scatter (from 544 to 393), and increased cytosolic Ca2+ concentration. 45Ca2+ flux measurements and patch clamp experiments revealed enhanced Ca2+ uptake (by 2.3-fold) and cation channel activity. The half-life of fluorescence-labeled, iron-deficient, or Ca2+-loaded erythrocytes was significantly reduced compared with control erythrocytes. Thus, the experiments reveal a novel mechanism triggered by iron deficiency, which presumably contributes to accelerated clearance of erythrocytes in iron deficiency anemia.

Abstract
Reactive oxygen species are involved in tumor promotion or apoptosis. In assaying prooxidant or antioxidant activities, cyanide has been commonly used as an inhibitor of mitochondrial oxidases, peroxidases, or Cu,Zn-superoxide dismutase, which have an influence on intracellular levels of reactive oxygen species. It has also been used to chemically mimic hypoxia. On the other hand, glycerol has been widely used as a stabilizer of various enzymes. In particular, glycerol is required to maintain the enzymatic activities of membrane-bound NAD(P)H oxidases extracted from surrounding phospholipids. Since both cyanide and glycerol are relatively inert, they have been used concomitantly regardless of any mutual interference. In this study, we demonstrate that a mixture of glycerol and cyanide reduced cytochrome c and nitroblue tetrazolium, both of which are superoxide anion indicators. The mixture also enhanced the production of superoxide anion in the presence of redox-cycling compounds. Superoxide production by the mixture was confirmed by electron spin resonance spectra. Moreover, the mixture induced lipid peroxidation and hemolysis in human erythrocytes. These results suggest that cyanide and glycerol should be used carefully in reaction systems used to measure superoxide production or antioxidant activity. However, sucrose and sodium azide in combination do not produce such artifacts and thus may be used as an alternative.

Abstract
Bidens pilosa is an annual plant from tropical America with anti-inflammatory properties in hepatitis, laryngitis, headache and digestive disorders, among others. Its wide pharmacological applications can be attributed to its chemical composition, with inhibitory effects on pathogenic microorganisms and flavonoids, which show strong antioxidant capacities. We investigated the antioxidant activity of an aqueous infusion of Bidens pilosa by studying its protective effect on the hemolysis induced by an initiator of radicals such as 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH). The immunomodulatory activity of the infusion was tested using whole blood cells. Cytokine production increased in whole blood stimulated or not by lipopolysaccharides (LPSs). The infusion is also characterized by its capacity to protect erythrocytes from the phototoxic effect of chlorpromazine, which allows its use as a potential photoprotector. Finally, it did not show ocular irritation, as demonstrated by the effect on hemoglobin denaturation. This study supports the health benefits of the ingestion of the infusion.

Abstract
Antrodia camphorata (A. camphorata) is well known in Taiwan as a traditional Chinese medicine. The purpose of this study was to evaluate the ability of aqueous extract from A. camphorata mycelia to protect normal human erythrocytes against oxidative damage in vitro. Oxidative hemolysis and lipid/protein peroxidation of erythrocytes induced by the aqueous peroxyl radical [2,2'-Azobis(2-amidinopropane) dihydrochloride, AAPH] were suppressed by A. camphorata mycelia in a time-and concentration-dependent manner. A. camphorata mycelia also prevented the depletion of cytosolic antioxidant glutathione (GSH) and ATP in erythrocytes. Moreover, cultured human endothelial cell damage induced by AAPH was suppressed by A. camphorata mycelia. Interestingly, A. camphorata mycelia exhibited significant cytotoxicity against leukemia HL-60 cells but not against cultured human endothelial cells. These results imply that A. camphorata mycelia may have protective antioxidant and anticancer properties.

Abstract
A negative association between anemia and duration of gestation and low birth weight has been reported in the majority of studies, although a causal link remains to be proven. This paper explores potential biological mechanisms that might explain how anemia, iron deficiency or both could cause low birth weight and preterm delivery. The risk factors for preterm delivery and intrauterine growth retardation are quite similar, although relatively little is understood about the influence of maternal nutritional status on risk of preterm delivery. Several potential biological mechanisms were identified through which anemia or iron deficiency could affect pregnancy outcome. Anemia (by causing hypoxia) and iron deficiency (by increasing serum norepinephrine concentrations) can induce maternal and fetal stress, which stimulates the synthesis of corticotropin-releasing hormone (CRH). Elevated CRH concentrations are a major risk factor for preterm labor, pregnancy-induced hypertension and eclampsia, and premature rupture of the membranes. CRH also increases fetal cortisol production, and cortisol may inhibit longitudinal growth of the fetus. An alternative mechanism could be that iron deficiency increases oxidative damage to erythrocytes and the fetoplacental unit. Iron deficiency may also increase the risk of maternal infections, which can stimulate the production of CRH and are a major risk factor for preterm delivery. It would be useful to explore these potential biological mechanisms in randomized, controlled iron supplementation trials in anemic and iron-deficient pregnant women.

Abstract
The effect of an intrinsic defect in the red cell and pronounced hypochromia on oxidative damage to RBC membrane lipids was compared in beta-thalassemia and iron deficiency anemia (IDA), which have a varied etiology but equivalent low hemogiobin content. The study was planned to correlate the etiology of the disorders to the severity of lipid imbalance and RBC hemolysis in membranes of both the conditions. Results indicated a fall of lysophosphatidylcholine(LPC), phosphatidylethanolamine(PE) and the unsaturated to saturated fatty acid ratio in both conditions, while phosphatidylcholine(PC) increased only in thalassemia. However, irrespective of the disease, sphingomyelin(SM), total cholesterol and phospholipid levels elevated and the hydrogen peroxide stress test indicated increased susceptibility of both pathologic RBCs to peroxidation. Present findings indicate that IDA and thalassemla, allow for considerable amounts of oxidative damage to membrane lipids, irrespective of their etiologles, and thus point hypochromia as an important contributor for inducing lipid imbalance and RBC hemolysis.

Abstract
Autoxidation of globin chains and iron overload are the suggested mechanisms for the increased oxidative stress in beta-thalassemia. The aim of this study was to evaluate the extend of lipid peroxidation and antioxidant status of patients with beta-thalassemia and iron deficiency anemia (IDA) and compare the results with healthy subjects. Oxidant and antioxidant status of the children with beta-thalassemia major (n = 22) and iron deficiency anemia (n = 19) were studied. Healthy controls (n = 14) were age and sex matched. Fresh anticoagulated venous blood samples were obtained from all children. Conjugated diene (CD) and thiobarbituric acid-reactive (TBARS) substances were analyzed to indicate the oxidative parameters, whereas the erythrocyte superoxide dismutase (SOD) and glutathione peroxidase (GPx) were measured to show the antioxidant status of the children. Plasma TBARS and CD concentrations were elevated in beta-thalassemia compared to IDA. When compared to the controls, elevation in TBARS was significant. In the iron-deficiency group both TBARS and CD levels were decreased compared to the controls. SOD and GPx activities were increased in the beta-thalassemia group. SOD in beta-thalassemia was higher than both IDA and the controls and GPx activity was higher than the IDA group. In vivo lipid peroxidation was increased in children with beta-thalassemia major. This leads to a compensatory increase in antioxidant enzymes, whereas IDA does not lead to lipid peroxidation with a normal antioxidant enzyme activity.

Abstract
In 1972, Valentine et al described, under the name of 'non-spherocytic haemolytic anaemia, high red cell ATP and ribose phosphate pyrophosphokinase (RPK; EC 2.7.6.1) deficiency', an obscure congenital haemolytic anaemia with the characteristic feature of red blood cell basophilic stippling. The activity of Embden-Meyerhof pathway and hexose monophosphate shunt were normal, and the concentrations of reduced glutathione and of ATP were raised 2 SD above the normal mean. The low values of RPK also encountered were considered to be an epiphenomenon rather than a causative defect. One year later, further studies performed in two new kindreds with the same haemolytic disorder associated with persistent basophilic stippling were described under the name of 'haemolytic disorders associated with increased ATP'. In 1974, two new and important observations contributed to the final identification of the disease: the patients' red blood cells (RBCs) contained large amounts of nucleotides (pyrimidine nucleotides), and in all cases they were deficient in a hitherto unrecognized enzyme called pyrimidine 5' nucleotidase (P5N). In conclusion, all these cases were formerly referred to as 'high ATP syndromes' because of the erroneous assumption that the large number of nucleotides within deficient RBCs were adenine phosphate rather than pyrimidine phosphate. Twenty-five years after its description, P5N deficiency has been reported in about 35 unrelated families from different parts of the world, and it has become one commonly identified cause of hereditary non-spherocytic haemolytic anaemia due to RBC enzymopathy. Genetic transmission is via the autosomic recessive mode, and only homozygous or compound heterozygous are clinically affected. Family members who are biochemically heterozygous are haematologically normal and difficult to detect. Unfortunately, the precise gene mutation or mutations causing the disease remain unknown.

Abstract
The protective effect of red wine polyphenols against hydrogen peroxide (H(2)O(2))-induced oxidation was investigated in normal human erythrocytes (RBCs). RBCs, preincubated with micromolar amounts of wine extract and challenged with H(2)O(2), were analyzed for reactive oxygen species (ROS), hemolysis, methemoglobin production, and lipid peroxidation. All these oxidative modifications were prevented by incubating the RBCs with oak barrel aged red wine extract (SD95) containing 3.5 mM gallic acid equivalent (GAE) of phenolic compounds. The protective effect was less apparent when RBCs were incubated with wines containing lower levels of polyphenols. Furthermore, resveratrol and quercetin, well known red wine antioxidants, showed lower antioxidant properties compared with SD95, indicating that interaction between constituents may bring about effects that are not necessarily properties of the singular components. Our findings demonstrate that the nonalcoholic components of red wine, mainly polyphenols, have potent antioxidant properties, supporting the hypothesis of a beneficial effect of red wine in oxidative stress in human system.

Abstract
Tea polyphenols (TPP) from black and green teas were evaluated for their antioxidant effects on normal red blood cells (RBC) and beta-thalassemic RBC membranes challenged with exogenous oxidants in vitro. The TPP of both types protected RBC against primaquine-induced lysis; they also protected the whole cells and the membranes against H2O2-induced lipid peroxidation so that about 80% protection was reached at [TPP] = 10 microg/mL. TPP from black tea at the same concentration protected normal RBC from morphological alterations caused by the peroxide treatment. The mechanism of the effects of TPP was investigated using a chemical system generating .OH (iron + ascorbic acid). TPP from both black and green teas inhibited the .OH fluxes in a concentration-dependent manner, indicating the possibility of iron chelation by TPP. Spectrophotometric titration revealed that TPP could stoichiometrically bind ferric iron to form a redox-inactive Fe-TPP complex. Quantitative analysis suggests that one or more major catechins from the TPP preparations are the likely iron-binding compounds accounting for the antioxidant effects of TPP on RBC.
