Non-transferrin-bound iron and its labile (redox active) plasma iron component are thought to be potentially toxic forms of iron originally identified in the serum of patients with iron overload. We compared ten worldwide leading assays (6 for non-transferrin-bound iron and 4 for labile plasma iron) as part of an international inter-laboratory study. Serum samples from 60 patients with four different iron-overload disorders in various treatment phases were coded and sent in duplicate for analysis to five different laboratories worldwide...

OBJECTIVES: Plasma markers in addition to serum ferritin (SF) may be useful for the assessment of iron overload; however, predictive utility may differ depending on underlying, transfusion-dependent, anemias. METHODS: Data were collected before and after 1 year of deferasirox treatment (end of study; EOS) from the large, 1-year EPIC (Evaluation of Patients' Iron Chelation with Exjade(®) ) study. Trends were evaluated between liver iron concentration (LIC), transferrin saturation (TfSat), predose labile plasma iron (LPI) and their relationship to SF categories in 1530 patients: thalassemia major (TM; n = 1114), myelodysplastic syndromes (MDS, n = 336), and sickle-cell disease (SCD, n = 80)...

Dysregulation of hepcidin, a key iron regulating hormone, is important in the pathogenesis of iron overload in patients with myelodysplatic syndrome (MDS). However, most studies of hepcidin levels are complicated by concomitant RBC transfusions. To evaluate the relationship between iron metabolism and erythropoiesis, we measured serum levels of hepcidin, growth-differentiation factor-15 (GDF15) and other markers of erythropoiesis in 107 subjects with MDS not receiving RBC transfusions. Patients with MDS had significantly higher levels of hepcidin than normals...

Patients with myelodysplastic syndromes (MDS) often show elevated serum ferritin levels at diagnosis, probably caused by increased intestinal iron uptake attributable to ineffective erythropoiesis. Many patients also develop transfusional iron overload. Hepcidin, a pivotal regulator of iron homeostasis, controls iron uptake in the duodenum as well as iron release from macrophages and is potentially involved in iron distribution to different organs. We measured serum hepcidin, together with other laboratory parameters related to iron metabolism and hematopoiesis (ferritin, transferrin, transferrin saturation, soluble transferrin receptor, erythropoietin, and hemoglobin), and C-reactive protein as marker of inflammation, in 89 MDS patients...

Anemia, the most common hematological disorder in the elderly, increases the risk of mortality and morbidity and adversely affects quality of life. However, few studies focused specifically on anemia in the elderly, especially regarding the underlying causes. The main objective of this prospective study was to evaluate the causes of anemia in non-institutionalized elderly patients. We included 190 consecutive patients ≥70 years, admitted to a geriatric short-stay unit over a 1-year period. When the hemoglobin level was <120 g/L, the following serum assays were performed routinely: iron, ferritin, transferrin saturation, folate, vitamin B12, C-reactive protein, TSH, albumin, and haptoglobin...

The incidence of HFE gene mutations in myelodysplastic syndrome (MDS) cases remains controversial. In this study, we examined the HFE C282Y and H63D mutations in 271 Chinese patients with MDS, 402 with aplastic anemia (AA) and 1,615 healthy controls by polymerase chain reaction-restriction fragment length polymorphism in combination with DNA sequencing. No C282Y mutations were observed in the entire cohort. The distribution of H63D heterozygous and homozygous genotypes was not significantly different between the AA cases and the controls (9...

BACKGROUND: Transfusion-related morbidity is an emerging problem in chronically transfused patients with myelodysplastic syndromes (MDS). Although several iron-chelating drugs are available, the optimal way of treatment of iron-overload remains uncertain. A major disadvantage of deferoxamine is that the drug has to be applied as continuous subcutaneous infusion. Therefore, novel oral agents have been developed. One of these drugs is deferasirox (Exjade). MATERIALS AND METHODS: We report on 14 MDS patients who were treated with deferasirox (500-1500 mg daily) for up to 24 months...

Most patients with myelodysplastic syndrome eventually become dependent on regular red cell transfusions. This dependency has a negative impact on clinical outcome, primarily because it may be associated with more severe marrow failure. In addition, however, transfusion dependency may involve clinical consequences of chronic anemia and iron overload. Although transfusion iron is primarily taken up by the reticuloendothelial cells, the metal is later redistributed to parenchymal cells. This redistribution is modulated by several factors, including the degree of ineffective erythropoiesis through its suppressive effect on hepcidin production...

The clinical experience of the significant difference in iron metabolism between multiple myeloma and myelodysplasia prompted us to analyse patients according to mutation frequency in the hemochromatosis gene (HFE) known to participate in the regulation of iron metabolism. HFE genotyping results were also evaluated in view of the clinical data in multiple myeloma (MM) patients. 49 patients with MM were compared to 61 patients with myelodysplastic syndrome (MDS) concerning the incidence of two genetic variants of the HFE gene (C282Y and H63D) identified with PCR-RFLP...

BACKGROUND: Myelodysplastic syndrome (MDS) is an iron overload condition. Copper deficiency itself might induce dysplastic changes and iron overload. The relationship between the iron and copper metabolism is analyzed in MDS patients. METHODS: Copper, iron and ceruloplasmin levels were established, and transferrin saturation determination and HFE mutation analysis were performed in 32 MDS patients. RESULTS: Eleven of 32 MDS patients were copper deficient...

Genotypic testing of nonselected patients with the myelodysplastic syndrome (MDS) for the C282Y and H63D mutations of the HFE gene responsible for hereditary hemochromatosis revealed a significantly increased frequency of these mutations when compared to healthy blood donors reflecting the average population. Among the 50 patients examined [26 refractory anemia (RA), 9 refractory anemia with ring sideroblasts (RARS), 2 refractory anemia with excess of blasts (RAEB) and 13 refractory anemia with excess of blasts in transformation (RAEB-t)] there were 24 heterozygotes (20 for H63D and 4 for C282Y), 1 homozygote for H63D and 1 compound heterozygote...

Effective management of early anaemia in the course of chronic renal insufficiency requires the following: (i) implementing an efficient diagnostic strategy to exclude common contributing factors; (ii) initiating epoetin therapy for the majority of patients; for and (iii) ensuring adequate iron supply erythropoiesis. Diagnostic inquiry is warranted whenever the haemoglobin concentration is below the normal range adjusted for age and gender. The most efficient diagnostic approach is to assume erythropoietin deficiency, exclude iron deficiency, and pursue further diagnostic tests only when red-cell indices are abnormal or when leukopenia or thrombocytopenia are also present...

The red cell ferritin (rFt) level in 10 patients with refractory anemia (RA) was measured and analyzed by column isoelectric focusing (IEF). The levels in 9 of the 10 patients (90.0%) were higher than the upper limit in healthy controls (MV +/- SD: male 14.3 +/- 10.3 ag/cell, female 7.5 +/- 3.6 ag/cell). The isoelectric point (pI) of rFt determined by IEF in healthy subjects ranged from 5.1 to 5.7. However, the pI ranges for RA patients varied widely; the pI value was thought to correlate with the severity of the morphological abnormalities of bone marrow (BM) erythroblasts...
