    Macrocytic anemia, defined as a mean cell volume (MCV) ≥100 fL in adults, has a narrow differential diagnosis that requires evaluation of the peripheral blood smear as well as additional laboratory testing taken in conjunction with clinical information that includes patient history and physical examination findings. This review is an update on the approach to a patient with macrocytic anemia with attention paid to the differentiation of megaloblastic and non-megaloblastic macrocytic anemias. Critical to the determination of the diagnosis is the judicious use of laboratory testing and the evaluation of those findings in conjunction with the patient medical, surgical, and medication history.

    A diagnosis of myelodysplastic syndrome, refractory anemia subtype, was made in an elderly Indian woman on the basis of a refractory macrocytic anemia with normal vitamin B(12) and folate assays, normal thyroid function, essentially normal liver function and normal cytogenetic analysis. Disease evolution revealed that the diagnosis was erroneous.

    Thymomas are often associated with autoimmune disorders. We report on a 45-year-old female patient with thymoma and hypogammaglobulinemia (Good's syndrome) who developed symptomatic macrocytic anemia (Hb 4.4 g/dl, MCV 112 fl) and thrombocytosis (Plt 442 G/l). Besides hypogammaglobulinemia (IgG 589 mg/dl), an inverted ratio of CD4(+)/CD8(+) cells was seen. The bone marrow biopsy showed a slightly hypercellular bone marrow with normal granulopoiesis, normal megakaryopoiesis and a mild dyserythropoiesis without any ring-sideroblasts. The in-vitro stem cell culture from the bone marrow revealed an atypical growth of macroclusters, reduced BFU-E and CFU-GEMM colony growth, whereas the CFU-GM colony growth was within the normal range. The chromosomal analysis showed a normal karyotype. The plasma vitamin B(12) and folate levels were within normal ranges, and we could not detect any autoantibodies. These findings excluded the differential diagnoses pure red cell aplasia (PRCA) and pernicious anemia. After resection of the thymoma of mixed cell type, the macrocytic anemia and thrombocytosis disappeared. The clinical course was complicated by a cerebral palsy and a life-threatening fungal septicemia after surgery. In the third year after thymectomy, hyporegenerative macrocytic anemia and thrombocytosis reappeared and an immunosuppressive treatment with prednisolone (1 mg/kg BW) was started. After initiation of the prednisolone therapy, reticulocyte counts increased and macrocytic anemia as well as thrombocytosis disappeared. The normalization of these laboratory parameters during glucocorticoid therapy suggests that in rare cases the constellation of macrocytic anemia, thrombocytosis and hypogammaglobulinemia may be due to an underlying immunologic mechanism.

    X-linked sideroblastic anemia (XLSA) is a rare hereditary disorder that typically manifests in males as microcytic anemia. Here, we report a family with XLSA that affects females and manifests as macrocytic anemia. The proband was a Japanese woman harboring a heterozygous mutation c.679C>T in the ALAS2 gene. This mutation causes the amino acid substitution R227C, which disrupts the enzymatic activity of erythroid-specific δ-aminolevulinic acid synthase. The mutation was not detected in the ALAS2 complementary DNA from peripheral blood red blood cells of the proband, indicating that the cells were mostly derived from erythroblasts expressing wild-type ALAS2. The proband's mother, who had been diagnosed with myelodysplastic syndrome, also had XLSA with the same mutation. Clinicians should be aware that XLSA can occur not only in males but also in females, in whom it manifests as macrocytic anemia.

    Azathioprine (AZA) is used clinically sometimes at high doses for short-term therapy to treat acute rejection of kidney allograft or to desensitize hypersensitive patients to it. The delayed consequences of this approach had not been well investigated. Therefore, in this study we have investigated the delayed consequences of high-dose short-term AZA administration in rabbits. Our results showed that oral administration of AZA (10 mg/kg/day) to rabbits for two weeks induced reversible thrombocytosis and delayed fatal macrocytic anemia. Moreover, neither the hemoglobin level nor the white blood cell count was affected by AZA. The solvent of AZA had no effect on blood cell counts and hemoglobin levels. We can conclude that although high-dose AZA therapy may not induce immediate and significant changes in blood picture, delayed fatal macrocytosis may occur.

    We used exome sequencing to identify mutations in sideroflexin 4 (SFXN4) in two children with mitochondrial disease (the more severe case also presented with macrocytic anemia). SFXN4 is an uncharacterized mitochondrial protein that localizes to the mitochondrial inner membrane. sfxn4 knockdown in zebrafish recapitulated the mitochondrial respiratory defect observed in both individuals and the macrocytic anemia with megaloblastic features of the more severe case. In vitro and in vivo complementation studies with fibroblasts from the affected individuals and zebrafish demonstrated the requirement of SFXN4 for mitochondrial respiratory homeostasis and erythropoiesis. Our findings establish mutations in SFXN4 as a cause of mitochondriopathy and macrocytic anemia.

    A 32-years-old man with a past history of hemorrhoids presenting with hemiparesis was diagnosed as having sagittal sinus thrombosis with hemorrtagic infarction. Laboratory data revealed macrocytic anemia (Hb 11.2 g/d/) with hypoproteinernia (5.5 g/d). After discharge the patient developed abdominal pain, diarrhea, edema in the leg and sustained anemia. Final diagnosis through colon fiberscope findings was Crohn's disease Macrocytic anemia seemed to be induced by Vit. B12 deficiency due to malabsorption. The mechanism and causal relationship between Crohn's disease and sinus thrombosis is discussed.

    A female rheumatoid arthritis patient was admitted for productive cough and general fatigue that had gradually developed after leflunomide therapy. Side effects including severe hypoxia, thrombocytopenia, lymphocytopenia, and macrocytic anemia with schistocytes (probably drug-induced megaloblastic anemia) were noted. Leflunomide-eliminating cholestyramine therapy successfully treated all conditions excluding severe hypoxia, which occurred owing to deteriorating interstitial pneumonia and complicated bacterial pneumonia following antibiotic treatment. This is a rare case of leflunomide-associated multiple hematopoietic impairments.

    We report the case of a 7 month-old girl that presented with acute anemia, generalized muscular hypotonia and failure to thrive. Laboratory evaluation revealed cobalamin deficiency, due to a vegan diet of the mother. The clinical triad of an acquired floppy baby syndrome with megaloblastic anemia and failure to thrive is pathognomic for infantile cobalamin deficiency. Neurological abnormalities are often irreversible and may be associated with delayed myelinization in the MRI. A normal cobalamin level in maternal serum and absence of anemia do not exclude subclinical deficiency. If cobalamin deficiency is suspected, e.g. in pregnant women on vegan diet, urinary methylmalonic acid excretion and plasma homocysteine levels should be determined and cobalamin substitution should be started at an early stage to avoid potentially irreversible damage of the fetus.

    Results: Primary bone marrow disorders were the most common cause of macrocytosis (46%. The other causes in decreasing order of frequency were megaloblastic anaemia (38%, hemolytic anemia (6%, drug induced (5%, alcoholism and liver disease (4% and idiopathic thrombocytopenic purpura (1%. There was a significant difference in the mean values of MCV and serum LDH between megaloblastic and non and ndash; megaloblastic macrocytosis. When serum LDH >1345.2 IU/L or MCV>121fl (criterion values of ROC curve with reticulocyte count <2% was taken as criteria, the sensitivity was 92.1% and specificity was 93.5% for diagnosing megaloblastic anemia. Conclusions: Systematic evaluation of macrocytosis will help us to distinguish megaloblastic and non and ndash; megaloblastic macrocytosis. The blood and biochemical parameters especially CBC, RC, and serum LDH along with supporting clinical features help us in diagnosing megaloblastic anemia in a setup where vitamin and metabolite levels are difficult to obtain.

    Macrocytic anemia with abnormal erythropoiesis is a common feature of megaloblastic anemias, congenital dyserythropoietic anemias, and myelodysplastic syndromes. Here, we characterized a family with multiple female individuals who have macrocytic anemia. The proband was noted to have dyserythropoiesis and iron overload. After an extensive diagnostic evaluation that did not provide insight into the cause of the disease, whole-exome sequencing of multiple family members revealed the presence of a mutation in the X chromosomal gene ALAS2, which encodes 5'-aminolevulinate synthase 2, in the affected females. We determined that this mutation (Y365C) impairs binding of the essential cofactor pyridoxal 5'-phosphate to ALAS2, resulting in destabilization of the enzyme and consequent loss of function. X inactivation was not highly skewed in wbc from the affected individuals. In contrast, and consistent with the severity of the ALAS2 mutation, there was a complete skewing toward expression of the WT allele in mRNA from reticulocytes that could be recapitulated in primary erythroid cultures. Together, the results of the X inactivation and mRNA studies illustrate how this X-linked dominant mutation in ALAS2 can perturb normal erythropoiesis through cell-nonautonomous effects. Moreover, our findings highlight the value of whole-exome sequencing in diagnostically challenging cases for the identification of disease etiology and extension of the known phenotypic spectrum of disease.

    There have been no studies on the distribution of causes of macrocytic anemia with respect to mean corpuscular volume (MCV) cutoff values. We retrospectively investigated the causes of macrocytic anemia (MCV ≥100 fL) among 628 patients who visited the outpatient hematology clinic in Tohoku University Hospital. To ensure data validity, we also analyzed data from 307 patients in eight other hospitals in the Tohoku district. The leading causes of macrocytic anemia (number of patients, %) were myelodysplastic syndromes (121, 19.3 %), suspected bone marrow failure syndromes (BMF; 74, 11.8 %), aplastic anemia (51, 8.1 %), plasma cell dyscrasia (45, 7.2 %), and vitamin B12 deficiency (40, 6.4 %) in Tohoku University Hospital. We made three primary findings as follows. First, the most common cause of macrocytic anemia is BMF. Second, lymphoid and solid malignancies are also common causes of macrocytosis. Third, macrocytic anemia may be classified into three groups: Group 1 (megaloblastic anemia and medications), which can exceed MCV 130 fL; Group 2 (alcoholism/liver disease, BMF, myeloid malignancy, and hemolytic anemia), which can exceed MCV 114 fL; and Group 3 (lymphoid malignancy, chronic renal failure, hypothyroidism, and solid tumors), which does not exceed MCV 114 fL. These conclusions were supported by the results from eight other hospitals.

    Case 1. The laboratory findings of a hematological analysis of a 53-year-old woman with palpitations and dyspnea revealed the following: red blood cell (RBC) count: 9.4×10(5)/μL with 60.0‰ reticulocytes; Hb: 3.7 g/dL; mean corpuscular volume (MCV): 124.5 fL; white blood cell (WBC) count: 2,800/μL with 10.0% myeloblasts. Case 2. Similarly, a 42-year-old man with dizziness had a RBC count of 1.63×10(6)/μL with 24.0% reticulocytes, an Hb level of 6.0 g/dL, an MCV of 120.2 fL and a WBC count of 3,100/μL with 4.0% myeloblasts. Bone marrow aspirates in both patients confirmed a diagnosis of acute erythroid leukemia (AEL), which can present as marked macrocytic anemia with an MCV in excess of 120 fL and hemolysis.

    Tribbles homolog 2 (Trib2) is a member of Tribbles protein pseudokinases and involves in apoptosis, autoimmunity, cancer, leukemia and erythropoiesis, however, the physiological function of Trib2 in hematopoietic system remains to be elucidated. Here, we report that Trib2 knockout (KO) mice manifest macrocytic anemia and increase of T lymphocytes. Although Trib2 deficient RBCs have similar half-life as the control RBCs, Trib2 KO mice are highly vulnerable to oxidant-induced hemolysis. Endogenous Trib2 mRNA is expressed in early hematopoietic progenitors, erythroid precursors, and lymphoid lineages, but not in mature RBCs, myeloid progenitors and granulocytes. Consistently, flow cytometric analysis and in vitro colony forming assay revealed that deletion of Trib2 mainly affected erythroid lineage development, and had no effect on either granulocyte or megakaryocyte lineages in bone marrow. Furthermore, a genetic approach using double knockout of Trib2 and C/ebpα genes in mice suggested that Trib2 promotes erythropoiesis independent of C/ebpα proteins in vivo. Finally, ectopic expression of human Trib2 in zebrafish embryos resulted in increased expression of erythropoiesis-related genes and of hemoglobin. Taking all data together, our results suggest that Trib2 positively promotes early erythrocyte differentiation and is essential for tolerance to hemolysis.

    Diamond Blackfan anemia (DBA) and myelodysplastic syndrome (MDS) with isolated del(5q) are severe macrocytic anemias; although both are associated with impaired ribosome assembly, why the anemia occurs is not known. We cultured marrow cells from DBA (n = 3) and del(5q) MDS (n = 6) patients and determined how heme (a toxic chemical) and globin (a protein) are coordinated. We show that globin translation initiates slowly, whereas heme synthesis proceeds normally. This results in insufficient globin protein, excess heme and excess reactive oxygen species in early erythroid precursors, and CFU-E (colony-forming unit-erythroid)/proerythroblast cell death. The cells that can more rapidly and effectively export heme or can slow heme synthesis preferentially survive and appropriately mature. Consistent with these observations, treatment with 10 μM succinylacetone, a specific inhibitor of heme synthesis, improved the erythroid cell output of DBA and del(5q) MDS marrow cultures by 68 to 95% (P = 0.03 to 0.05), whereas the erythroid cell output of concurrent control marrow cultures decreased by 4 to 13%. Our studies demonstrate that erythropoiesis fails when heme exceeds globin. Our data further suggest that therapies that decrease heme synthesis (or facilitate heme export) could improve the red blood cell production of persons with DBA, del(5q) MDS, and perhaps other macrocytic anemias.

    The identification of the genes associated with chromosomal translocation breakpoints has fundamentally changed understanding of the molecular basis of hematological malignancies. By contrast, the study of chromosomal deletions has been hampered by the large number of genes deleted and the complexity of their analysis. We report the generation of a mouse model for human 5q- syndrome using large-scale chromosomal engineering. Haploinsufficiency of the Cd74-Nid67 interval (containing Rps14, encoding the ribosomal protein S14) caused macrocytic anemia, prominent erythroid dysplasia and monolobulated megakaryocytes in the bone marrow. These effects were associated with defective bone marrow progenitor development, the appearance of bone marrow cells expressing high amounts of the tumor suppressor p53 and increased bone marrow cell apoptosis. Notably, intercrossing with p53-deficient mice completely rescued the progenitor cell defect, restoring common myeloid progenitor and megakaryocytic-erythroid progenitor, granulocyte-monocyte progenitor and hematopoietic stem cell bone marrow populations. This mouse model suggests that a p53-dependent mechanism underlies the pathophysiology of the 5q- syndrome.

    Although macrocytic anemia can develop in patients with acute blood loss, such anemia in very old patients is uncommon. In this report, we describe the course of an 89-year-old woman who had a rapid recovery from macrocytic anemia by medication only after acute blood loss due to a gastric ulcer. She had been treated with antihypertensive drugs for the previous 28 years at our outpatient clinic, and was admitted because of acute anemia 6 days after she had experienced tarry stool. Her hemoglobin (Hb) count and mean corpuscular volume (MCV) were 8.4 g/dl, and 103 fl, respectively. A gastroscopic examination indicated that the tarry stool originated from a fresh gastric ulcer. She was treated with an iron preparation, a diuretic and a proton pump inhibitor. The anemia was rapidly improved to Hb 10.5 g/dl and MCV 106 fl in one week, and to Hb 14.5 g/dl and MCV 99 fl in 4 weeks. At admission, she had slight pleural effusion and slight edema associated with an increase in her plasma brain natriuretic peptide (BNP) level (323 pg/ml), and her left ventricular ejection fraction was 76% based on the echocardiography findings, which are signs of the high-output heart failure without remarkable left ventricular diastolic dysfunction (E/e': 11.2). However, these signs improved rapidly, and her BNP level thereafter decreased to 114 pg/ml within four weeks.

    Hemodynamic changes occur in pregnancy to prepare for expected blood loss at delivery. Physiologic anemia occurs in pregnancy because plasma volume increases more quickly than red cell mass. Anemia is most commonly classified as microcytic, normocytic, or macrocytic. Iron deficiency anemia accounts for 75% of all anemias in pregnancy. Oral iron supplementation is the recommended treatment of iron deficiency anemia in pregnancy. Parenteral iron and erythropoietin can also be used in severe or refractory cases. Outcomes and treatments for other forms of inherited and acquired anemias in pregnancy vary by disease, and include nutritional supplementation, corticosteroids, supportive transfusions, and splenectomy.

  9. Laboratory Evaluation of Anemia

    OpenAIRE

    The laboratory evaluation of anemia begins with a complete blood count and reticulocyte count. The anemia is then categorized as microcytic, macrocytic or normocytic, with or without reticulocytosis. Examination of the peripheral smear and a small number of specific tests confirm the diagnosis. The serum iron level, total iron-binding capacity, serum ferritin level and hemoglobin electrophoresis generally separate the microcytic anemias. The erythrocyte size-distribution width may be particul...

    Anemias continue to present a challenge to the health care profession. Anemia is defined as a reduction in one or more of the RBC indices. Patients presenting with a mild form of anemia may be asymptomatic; however, in more serious cases the anemia can become life threatening. In many cases the clinical presentation also reflects the underlying cause. Anemia may be attributed to various causes, whereas autoimmune RBC destruction may be attributed to intrinsic and extrinsic factors. Laboratory tests are essential in facilitating early detection and differentiation of anemia.

    Anemia is defined as a hemoglobin level of less than the 5th percentile for age. Causes vary by age. Most children with anemia are asymptomatic, and the condition is detected on screening laboratory evaluation. Screening is recommended only for high-risk children. Anemia is classified as microcytic, normocytic, or macrocytic, based on the mean corpuscular volume. Mild microcytic anemia may be treated presumptively with oral iron therapy in children six to 36 months of age who have risk factors for iron deficiency anemia. If the anemia is severe or is unresponsive to iron therapy, the patient should be evaluated for gastrointestinal blood loss. Other tests used in the evaluation of microcytic anemia include serum iron studies, lead levels, and hemoglobin electrophoresis. Normocytic anemia may be caused by chronic disease, hemolysis, or bone marrow disorders. Workup of normocytic anemia is based on bone marrow function as determined by the reticulocyte count. If the reticulocyte count is elevated, the patient should be evaluated for blood loss or hemolysis. A low reticulocyte count suggests aplasia or a bone marrow disorder. Common tests used in the evaluation of macrocytic anemias include vitamin B12 and folate levels, and thyroid function testing. A peripheral smear can provide additional information in patients with anemia of any morphology.

    hereditary anemias of mice have been the chief objects of investigation. At present under study are four macrocytic anemias, five hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, an ..cap alpha..-thalassemia, and a new target-cell anemia. Each of these blood dyscrasias is caused by the action of a unique mutant gene, which determines the structure of different intracellular molecules, and thus controls a different metabolic process. Thus our wide range of different hereditary anemias has considerable potential for uncovering many different aspects of hemopoietic homeostatic mechanisms in the mouse. Each anemia is studied through: (a) characterization of peripheral blood values, (b) determinations of radiosensitivity under a variety of conditions, (c) measurements of iron metabolism and heme synthesis, (d) histological and biochemical study of blood-forming tissue, (e) functional tests of the stem cell component, (f) examination of responses to erythroid stimuli, and (g) transplantation of tissue between individuals of differently affected genotypes.

    Results: 17,552 second and third trimester pregnant females were evaluated and prevalence of anemia was found 48.4%. The percentages of mild, moderate and severe anemia were 35.1%, 51.3% and 13.4% respectively. Most common morphological type was microcytic hypochromic anemia (51% followed by normocytic normochromic anemia (32%, dimorphic anemia (13% and macrocytic anemia (4%. Conclusions: There is high prevalence of anemia in pregnant females. This warrants the need of proper prophylaxis and early diagnosis of anemia in pregnancy to minimize the maternal-fetal morbidity and mortality. [Int J Res Med Sci 2016; 4(11.000: 4797-4799

    2015-08-01

    Full Text Available Introduction: We present the case of a 65 years- old woman who was admitted with a severe macrocytic anemia Hb= 5.7g/dl and diffuse bone pain. Biologically she has moderate thrombocytopenia 35 000/µl, a hepatic cytolysis and cholestatic syndrome. Material and method: The patient was extensively evaluated before presentation for a mild iron - deficiency anemia for which she underwent endoscopic examination of the upper and lower gastrointestinal tract- normal. The bone marrow aspiration on admission revealed a marked hyperplasia of the erythroblastic line with ~50% basophilic erythroblasts suggesting a regenerative erythroid hyperplasia. These changes along with the marked reticulocytosis on the peripheral blood smear oriented us towards a hemolytic anemia; Folic acid, vitamin B12, autoimmune tests and hemolytic tests were all normal. We continued the investigations with a thoraco-abdominopelvic computed tomography which identified diffuse demineralization, vertebral compactation and pelvic stress fractures. The breast examination revealed a right breast nodule, but the breast ultrasonography pleaded for benignity. Lacking a clear definitive diagnosis we decided to perform a bone marrow biopsy. Results: The osteo- medullary biopsy pointed towards a medullar invasion from a lobular mammary carcinoma; In these circumstances we performed an ultrasound guided biopsy of the right mammary lump thus histologically confirming a tumoral invasion of the bone marrow with subsequent anemia. The patient started chemotherapy in the Oncology ward. Conclusion: The particularity of this case consists in the pattern of anemia, which initially seemed iron deficient and afterwards macrocytic – apparently hemolytic and was actually due to the tumoral medullar invasion and also the nonspecific ultrasonographic appearance of the breast tumor.

    Nutritional deficiency anaemia in vegans is common and usually due to lack of vitamin B12, as this vitamin is found almost exclusively in animal-based food products. In this case report we present a 39-year-old male vegan with severe macrocytic anaemia due to vitamin B12 deficiency as well as secondary hyperparathyroidism due to severe vitamin D deficiency. We want to emphasize the importance of a detailed nutritional history for patients with anaemia, and the need for vitamin B12 and vitamin D supplements for people who comply with a vegan diet.

    The pathogenetic mechanisms of anemia in patients with chronic liver disease were observed. Seventeen patients with moderate to advanced hepatic diseases were studied by various methods. Only patients without previous blood loss were included : 14 had cirrhosis, 2 had active chronic hepatitis, and one had inferior vena cava obstruction with associated liver cirrhosis. The followings were the results: 1. The anemia based on red blood cell count, Hb., and Ht. was found in 76.5-78.6% of the patients. 2. Red cell indices indicated that normo-macrocytic and normochromic anemia was present is the majority of the patients. 3. No evidence of megaloblastic anemia was found on the basis of the morphological examinations. 4. Serum iron, TIBC, % saturation and iron content in the bone marrow indicated that iron deficiency anemia was present in about half of the patients. 5. In the view of the erythrocyte dynamics, primary increase in the red cell destruction was ascribed to the cause of the anemia. 6. Decrease in the red cell survival time was not correlated with MCV, % saturation and S.L. ratio. Also, hemoglobin level was not correlated with MCV, % saturation and T{sub 50} Cr. Therefore, multiple causes may be involved in the pathogenesis of the anemia. 7. Anemia as determined by the red cell volume was found in only 60% of the patients. It may be possible that hemodilutional anemia is present.

    Most anemia is related to the digestive system by dietary deficiency, malabsorption, or chronic bleeding. We review the World Health Organization definition of anemia, its morphological classification (microcytic, macrocytic and normocytic) and pathogenic classification (regenerative and hypo regenerative), and integration of these classifications. Interpretation of laboratory tests is included, from the simplest (blood count, routine biochemistry) to the more specific (iron metabolism, vitamin B12, folic acid, reticulocytes, erythropoietin, bone marrow examination and Schilling test). In the text and various algorithms, we propose a hierarchical and logical way to reach a diagnosis as quickly as possible, by properly managing the medical interview, physical examination, appropriate laboratory tests, bone marrow examination, and other complementary tests. The prevalence is emphasized in all sections so that the gastroenterologist can direct the diagnosis to the most common diseases, although the tables also include rare diseases. Digestive diseases potentially causing anemia have been studied in preference, but other causes of anemia have been included in the text and tables. Primitive hematological diseases that cause anemia are only listed, but are not discussed in depth. The last section is dedicated to simplifying all items discussed above, using practical rules to guide diagnosis and medical care with the greatest economy of resources and time.

    Biermer disease or pernicious anemia is an autoimmune atrophic gastritis characterized by the lack of secretion of gastric intrinsic factor. This leads to an insufficient absorption of vitamin B12 in the ileum. Clinical manifestations are mainly hematologic. Neuropsychiatric manifestations are known but are less frequent especially early in the disease. Inaugural neuropsychiatric arrays are rare and various thus making diagnosis difficult. In this article, we report through two clinical cases different neuropsychiatric manifestations revealing pernicious anemia. Mrs. C.O., aged 56, presented after surgery for gallstones, an acute psychiatric array associated with gait disorders. She had no history of neurological or psychiatric problems. The psychiatric interview revealed delirious syndrome, depressive symptoms and anxiety. Neurological examination noted a flaccid paraplegia with peripheral neuropathic syndrome and myoclonus in the upper limbs. At the full blood count, a macrocytosis (VGM: 112.2fl) without anemia was found. The level of vitamin B12 in the blood was low. Cerebro-spinal MRI was suggestive of a neuro-Biermer and showed hyper signal in the cervical cord on T2-weighted sagittal section. In axial section, hyper signal appears at the posterior columns in the form of V. There were no brain abnormalities. A sensorimotor axonal polyneuropathy was diagnosed. The patient received vitamin B12 intramuscularly for ten days associated with neuroleptic treatment. Mrs. R.M., aged 40, was brought to the psychiatry consultation for acute behavioral disorders progressively worsening over a month. An anxiety syndrome, depressive syndrome and delirious syndrome were identified. Neurological examination showed a posterior cordonal syndrome with quadripyramidal syndrome. Full blood count showed a macrocytic anemia. Serum B12 level was collapsed. Cerebro-spinal MRI was normal. She received vitamin B12 with clinical and biological improvement.

    Full Text Available Fanconi Anemia (FA is a rare autosomal recessive disorder affecting multiple body systems. The diagnosis is based on morphological abnormalities, hematological abnormalities (pancytopenia, macrocytic anemia and progressive bone marrow failure and genetic testing. However, genetic testing is complicated for FA because there are often many genes that are associated with its development, and large duplications, deletions or sequence variations are frequently observed in some of these genes. We report a patient with cytogenetically confirmed Fanconi anemia. Although morphological abnormalities were present from birth, diagnosis was suspected and made at 8 years of age when he presented to us. We report this case to create awareness among clinicians to use modern modalities of diagnosis for such cases in addition to the clinical assessment. This would further help these children reach their adulthood with good quality of life. [Int J Res Med Sci 2015; 3(4.000: 998-1001

    Thyroid hormones stimulate directly or indirectly growth of erythroid colonies through erythropoietin. Anemia is often the first sign of hypothyroidism. Hypothyroidism can cause a wide variety of anemic disorders. Numerous mechanisms are involved in the pathogenesis of these anemias that can be microcytic, macrocytic and normocytic. We designed this study to investigate the anemia frequency and if present, etiology of anemia in hypothyroid patients. 100 patients with overt hypothyroid, 100 patients with subclinical hypothyroid, and 200 healthy controls were enrolled in this study. Overt hypothyroidism diagnosis is done when elevated TSH and low levels of free T4 and/or free T3 have been observed. Subclinical hypothyroidism is defined as elevated serum TSH with normal free T(4) and free T(3) levels. Peripheral smears of the anemic patients were examined. Anemia prevalence was 43% in the overt hypothyroid group, 39% in the subclinical hypothyroid group, and 26% in the control group (p=0.0003 and p=0.021 respectively related to controls). Thus, the frequency of anemia in subclinical hypothyroidism is as high as that in overt hypothyroidism. There was no difference between the hypothyroid groups in terms of anemia. Vitamin B12, Fe, and folic acid were similar between these groups. According to our findings, anemia of chronic disease is the most common type of anemia in hypothyroid patients. Suspicion of hypothyroidism should be considered in anemias with uncertain etiology.

    2007-12-01

    Autoimmune hemolytic anemia (AIHA) is diagnosed in the presence of anemia, usually macrocytic and of variable intensity, reticulocytosis, and a positive direct and/or indirect antiglobulin test, after ruling out other types of hemolytic anemia. A positive direct antiglobulin test alone is not sufficient to diagnose AIHA and may be positive in many patients without anemia or negative in some patients with AIHA. AIHA may be classified into two major categories according to the optimal temperature of antibody activity: warm-reacting autoantibodies (usually IgG) optimal around 37 degrees C and cold-reacting autoantibodies, optimal at 4 degrees C (usually IgM). This classification guides the selection of tests and treatment. AIHA is widely reported to be associated with a variety of other diseases, although these associations are often fortuitous. A minimal set of useful investigations is appropriate since AIHA may be secondary to viral infections, lymphoid malignancies, or autoimmune disorders such as lupus. Transfusion should remain rare in AHAI, but close contact with the transfusion service is necessary if it is to succeed. As for many autoimmune and/or systemic diseases, numerous types of treatment have been proposed but have not been validated in controlled multicenter studies. These are necessary to improve the management of these rare disorders.

Father hematological and immunological research is needed to secure information on hematological parameters in different avian species at their earliest age. Anemia is a common clinical finding in birds because the avian erythrocyte half - life is much shorter than the mammalian. Therefore anemia should be determined as soon as possible. Researchers should standardize hematological parameters for every single avian species.

    Full Text Available Background: Anemia is a medical condition in which the red blood cells (RBCs count and hemoglobin (Hb are less than the normal range. The main causes of anemia are a decrease in RBCs, their destruction and decrease of Hb synthesis. A useful method for diagnosis and classification of anemias is based on the morphological appearance of RBCs on an ideal stained blood smear. The main terms used in such classification are normocytic normochromic, microcytic hypochromic and macrocytic anemia. Aim: The aim of this study is to determine the most common morphological pattern of anemia in Saudi anemic patients who were admitted at King Abdul-aziz Medical City-Riyadh. Materials and Methods : Retrospectively we evaluated the results of complete blood count (CBC and peripheral blood picture (PBP of all anemic patients attending during the year 2013 (from 1 st January to 31 st December. Results: Participants in this study included 150 patients (13 infants, 27 children, 12 youths, 52 adults and 46 old. The gender distribution showed 70 males and 80 females. The results of CBC and PBP showed that 113 (75.3%, 36 (24% and 1 (0.7% of the patients had normocytic normochromic, microcytic hypochromic and macrocytic pattern of anemia respectively. Conclusion: The normocytic normochromic pattern of anemia is highly frequent among this sample of Saudi patients while the macrocytic pattern of anemia is the lowest. According to gender groups microcytic hypochromic pattern of anemia is more common among females; malnutrition, increase of blood loss due to pregnancy or menstruation, and lack of iron absorption are the main causes, while the normocytic normochromic is highly frequent among males, which are mainly due to blood loss or chronic diseases.

    Purpose The purpose of this study was to evaluate and characterize the risk of anemia during the course of chemotherapy among patients with five common types of solid tumors. Patients and methods Patients diagnosed with incident cancers of breast, lung, colon/rectum, stomach, and ovary who received chemotherapy were identified from Kaiser Permanente Southern California Health Plan (2010–2012). All clinical data were collected from the health plan’s electronic medical records. Incidence proportions of patients developing anemia and 95% confidence intervals were calculated overall and by anemia severity and type, as well as by stage at cancer diagnosis, and by chemotherapy regimen and cycle. Results A total of 4,426 patients who received chemotherapy were included. Across cancers, 3,962 (89.5%) patients developed anemia during the course of chemotherapy (normocytic 85%, macrocytic 10%, microcytic 5%; normochromic 47%, hyperchromic 44%, hypochromic 9%). The anemia grades were distributed as follows: 58% were grade 1, 34% grade 2, 8% grade 3, and anemia ranged from 26.3% in colorectal cancer patients to 59.2% in ovarian cancer patients. Incidence of grade 2+ anemia increased from 29% in stage I to 49% in stage IV. Incidence of grade 2+ anemia varied from 18.2% in breast cancer patients treated with cyclophosphamide + docetaxel regimen to 59.7% in patients with ovarian cancer receiving carboplatin + paclitaxel regimen. Conclusion The incidence of moderate-to-severe anemia (hemoglobin anemia was greater in patients with distant metastasis. PMID:27186078

    A 73-year-old Japanese man with Hashimoto's disease and diabetes mellitus received regular medical checkups for type 2 diabetes care. Blood tests indicated macrocytic anemia (red blood cell count, 279×104 /μL; hemoglobin, 12.2 g/dL; hematocrit, 34.0%; mean corpuscular volume, 121.9 fL). The laboratory data demonstrated a normal folic acid level with a low vitamin B12 level. An endoscopic examination indicated no signs of gastric or intestinal bleeding. Positive results for anti-intrinsic factor antibodies were strongly suggestive of pernicious anemia. The patient refused cobalamin injections to treat the anemia. However, the oral administration of mecobalamin for the treatment of diabetic neuropathy was simultaneously initiated. Subsequently, the anemia gradually improved. Oral mecobalamin was presumably effective for pernicious anemia management. Anemia is frequently observed in elderly patients, and the incidence of pernicious anemia increases with age. Anemia is conventionally treated with cobalamin injections. Currently, the oral administration of mecobalamin is not the typical treatment for anemia. However, as in our case, a few reports have documented positive results following oral mecobalamin treatment. Moreover, oral mecobalamin is a fairly recent, novel, noninvasive mode of treatment, making it ideal for elderly patients, who are generally frail. This case suggests the efficacy of mecobalamin for the treatment of pernicious anemia.

    Full Text Available This paper intends to shed extra light on different types of anemia as caused by multiple myeloma in patients registered at “ Elena Beldiman” Municipal Emergency Hospital from Barlad, between 2001-1012. In order to complete this characterization, the values of derived erythrocyte constants have been used: the average volume of erythrocytes (VEM; mean erythrocyte hemoglobin (HEM and the average concentration of erythrocyte hemoglobin (CHEM. Moreover, this paper aims to compare the different types of anemia in patients with multiple myeloma, according to their gender and age. The 34 identified patients were divided into four study groups, men and women aged under 60, respectively over 60 years.         It has been noticed that the incidence of macrocytic anemia (increased VEM coexists with hypochromia (decreased CHEM, and the values from the four study groups are comparable, both types of anemia having mollified levels of severity, both in male patients and female patients.

    The neurological condition triggered by anaesthesia with nitrous oxide involves the cyanocobalamine pathway and is characterised by progressive demyelination and axonal lesions of the peripheral nerves and cervicothoracic spinal cord (posterior and anterolateral columns) giving a peripheral neuropathy and very frequently subacute combined degeneration of the spinal cord. It is possible to show these demyelinating lesions by MRI of the spine, allowing early diagnosis and follow-up. We describe a case of myeloneuropathy with onset a few hours after nitrous oxide anaesthesia in a patient with macrocytic anaemia and possible subclinical vitamin B{sub 12} deficiency and MRI evidence of a lesion of the cervical spinal cord. Neurological and haematological improvement followed cyanocobalamine replacement. (orig.) With 2 figs., 15 refs.

    Hereditary anemias of mice have been the chief objects of investigation. At present under study are four macrocytic anemias, four hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, and the autoimmune hemolytic anemia of NZB. Each of these blood dyscrasias is caused by the action of a unique mutant gene, which determines the structure of different intracellular molecules, and thus controls a different metabolic process. Thus our wide range of different hereditary anemias has considerable potential for uncovering many different aspects of hemopoietic homeostatic mechanisms in the mouse. Each anemia is studied through: characterization of peripheral blood values, determinations of radiosensitivity under a variety of conditions, measurements of iron metabolism and heme synthesis, histological and biochemical study of blood-forming tissue, functional tests of the stem cell component, examination of responses to erythroid stimuli, and transplantation of tissue between individuals of differently affected genotypes. Considerable effort is devoted to perfection of hematologic, cell culture, and transplant methods to make these techniques useful in dealing with special problems associated with abnormal function.

  5. Anemia as the Main Manifestation of Myelodysplastic Syndromes.

    Santini, Valeria

    2015-10-01

    Myelodysplastic syndromes (MDS) are a constellation of different diseases sharing anemia in the great majority of cases, and this cytopenia defines these pathologies and their most dramatic clinical manifestations. Anemia in MDS is due to ineffective erythropoiesis, with a high degree of apoptosis of marrow erythroid progenitors. These progenitors show distinctive dysplastic features that consent diagnosis, and are recognizable and differentiated, although not easily, from other morphologic alterations present in other types of anemia. Reaching the diagnosis of MDS in a macrocytic anemia and alleviating the symptoms of anemia are therefore an essential objective of the treating physician. In this work, the signs and symptoms of anemia in MDS, as well as its peculiar pathophysiology, are discussed. Erythopoietic stimulating agents (ESAs) are providing the best treatment for anemic MDS patients, but their use is still not approved by health agencies. While still waiting for this waiver, their clinical use is widespread and their effectivness is well known, as well as the dismal prognosis of patients who do not respond to ESAs and require transfusions. MDS with del5q constitute a unique model of anemia whose complex pathophysiology has been clarified at least partially, defining its link to ribosomal alterations likewise what observed in hereditary anemias like Blackfan Diamond anemia. Lenalidomide is the agent that has shown striking and specific erythropoietic activity in del5q MDS, and the basis of this response is starting to be understood. Several new agents are under evaluation for ESA refractory/relapsed MDS patients, targeting different putative mechanisms of ineffective erythropoiesis, and are here reviewed.

    Low hemoglobin concentration is associated with increased mortality, but there is disagreement with regard to the clinical definition of anemia. We aimed to evaluate the prevalence, clinical correlates and association with total and cause-specific long-term mortality across the hemoglobin distribution and for previously proposed definitions of anemia. Blood hemoglobin concentration and mean corpuscular volume was measured in participants of the Malmö diet and cancer study-a prospective cohort study, and related to baseline characteristics and outcomes during follow-up. Primary endpoints were all-cause mortality, cardiovascular mortality and cancer-related mortality. A U-shaped association of hemoglobin with total mortality was observed in spline regression analyses, with nadir at hemoglobin 150 g/L among men and 130 g/L among women. Mortality increased steeply with more strict definitions of anemia, hazard ratio: 1.36, 1.94 and 2.16 for hemoglobin macrocytic anemia, which was less prevalent than microcytic and normocytic anemia. Dietary intake of iron and vitamin B12 were significantly lower and use of antithrombotic medications was significantly higher in subjects with anemia. The World Health Organisation definition of anemia was associated with increased mortality (hazard ratio 2.16) but excess mortality was also observed at higher hemoglobin levels. Of morphological subtypes, anemia with macrocytosis was rare but associated with the highest mortality.

    Full Text Available Diamond-Blackfan anemia (DBA is a congenital erythroid hypoplastic anemia, characterized by macrocytic anemia, reticulocytopenia, and severely reduced numbers of erythroid precursors in the bone marrow. For more than fifty years, glucocorticoids have remained the main option for pharmacological treatment of DBA. While continuous glucocorticoid administration increases hemoglobin levels in a majority of DBA patients, it also causes severe side effects. There is therefore a great need for more specific and effective treatments to boost or replace the use of glucocorticoids. Over the years, many alternative therapies have been tried out, but most of them have shown to be ineffective. Here we review previous and current attempts to develop such alternative therapies for DBA. We further discuss how emerging knowledge regarding the pathological mechanism in DBA and the therapeutic mechanism of glucocorticoids treatment may reveal novel drug targets for DBA treatment.

    Full Text Available Summary Objective: Anemia, a common complication of chronic kidney diseases (CKD, is involved in significant cardiovascular morbidity. Therefore, the objective of our study was to investigate the prevalence and severity of anemia in pre-dialysis patients, as well as to determine the predictors of anti-anemic therapy. Method: A retrospective, observational study was conducted on adult pre-dialysis patients receiving treatment at the Hospital Universiti Sains Malaysia from January 2009 to December 2013. Results: A total of 615 eligible cases were included. The mean age of patients was 64.1±12.0 years. The prevalence of anemia was 75.8%, and the severity of anemia was mild in 47.7% of the patients, moderate in 32.2%, and severe in 20%. Based on morphological classification of anemia, 76.9% of our patients had normochromic-normocytic anemia whereas 21.8 and 1.3% had hypochromic-microcytic anemia and macrocytic anemia, respectively. Oral iron supplements were prescribed to 38.0% of the patients and none of the patients was given erythropoietin stabilizing agents (ESA or intravenous iron preparations. In logistic regression, significant predictors of anti-anemic preparation use were decreased hemoglobin and hematocrit, and advanced stages of CKD. Conclusion: The results of the present study suggest that the prevalence of anemia in pre-dialysis patients is higher than currently accepted and it is found to be correlated with renal function; prevalence increases with declined renal function. An earlier identification as well as appropriate management of anemia will not only have a positive impact on quality of life but also reduce hospitalizations of CKD patients due to cardiovascular events.

  3. [Sideroblastic anemias].

    Science.gov (United States)

    Matthes, T

    2006-01-01

    Sideroblastic anemias are a heterogenous group of disorders characterized by the presence of sideroblasts in the bone marrow aspirate. Current classification schemes distinguish between diseases of the heme synthesis pathway and diseases of other mitochondrial pathways which can either be of primary origin (defects in mitochondrial DNA) or of secondary origin (defects in nuclear DNA). Although several distinct hereditary forms exist, sideroblastic anemias are most frequently acquired diseases and belong to the group of myelodysplastic syndromes with the propensity to develop into overt leukemia. Treatment is mainly supportive (vitamins, blood transfusions, cytokines) and only rarely are bone marrow transplantations performed. The molecular defects of a few hereditary forms have already been elucidated, but the genes involved in the acquired forms are still largely unknown.

    1982-07-01

    Hereditary anemias of mice have been investigated including four macrocytic anemias, three hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, an ..cap alpha..-thalassemia, and a new target-cell anemia. Each of these blood dyscrasias is caused by the action of a unique mutant gene, which determines the structure of different intracellular molecules controlling a different metabolic process. Thus the wide range of different hereditary anemias has considerable potential for uncovering many different aspects of hemopoietic homeostatic mechanisms in the mouse and by extension to man from an understanding of mammalian mechanisms utilized in the control of erythropoiesis. Each of the different anemias is studied through: (a) biochemical and biophysical characterization of peripheral blood cells; (b) determinations of cellular and organismic radiosensitivity under a variety of conditions; (c) measurements of iron metabolism and heme biosynthesis; (d) morphological and biochemical study of blood-forming tissue; (e) functional tests of the stem cell component; (f) examination of responses to erythroid stimuli and inhibitors; and (g) physiological complementation analysis via transplantation of tissue between individuals of differently affected genotypes.

    In order to study the value of RDW/MCV classification on clinical application, blood, which was anti-coagulated by EDTA was detected using a blood cell analysor (type K-4500). As a result, anemia was classified into six types, i.e, microcytic homogeneity (for example, α ,β-thalassemia), microcytic non-homogeneity (for example, iron-deficiency anemia, IDA), macrocytic homogeneity, macrocytic non-homogeneity (for example, megaloblastic anemia), normal cell homogeneity (for example, massive hemorrhagic anemia) and normal cell non-homogeneity. This study indicates that RDW/MCV is a valuable marker in diagnosing and differentiating the diagnosis of anemia, especially for the screening and diagnosing of microcytic anemia, such as IDA and the light grade of α,β- thalassemia.%为研究RDW/MCV分类法在临床中的应用,将EDTA盐抗凝血于K-4500型血细胞分析仪上检测。结果可将贫血分为六类,即小细胞均一性(如α、β-地贫)、小细胞不均一性(如缺铁性贫血)、大细胞均一性、大细胞不均一性(如巨幼贫)、正细胞均一性(大失血性贫血)和正细胞不均一性。认为RDW/MCV给临床医生对贫血诊断及鉴别诊断提供很有价值的筛选和诊断指标,尤其是对小细胞性贫血,如IDA与α、β-轻型地中海贫血的筛选和鉴别诊断。

    Objective: To study importance of anemia laboratory indexes in diagnosis and treatment of anemia. Methods:4330 cases of anemia were selected, the ratio of male to female patients and anemia type were statistically analyzed. The levels of ser-um ferritin, folic acid and vitamin B12 were analyzed. Results:Among the 4 330 cases, there were 2 254 male patients and 2 076 fe-male patients. Among the male patients, there were 208 cases with microcytic hypochromic anemia, and 194 cases with macrocytic a-nemia;while among the female patients, there were 302 cases with microcytic hypochromic anemia, and 77 cases with macrocytic ane-mia. The serological examination showed that:among the patients with macrocytic anemia, the percentage of vitamin B12 decrease was lower with the ratio of male to female patients of being close to 1:3, but the percentage of folic acid decrease was greater with the ratio of being close to 1. 2:1;among the patients with microcytic anemia, the ratio of male to female patients was close to 2:3; among the patients with microcytic hypochromic anemia, the percentage of serum ferritin combined with folic acid and/or vitamin B12 decrease was 5%. Among 781 cases with macrocytic anemia ﹢microcytic hypochromic anemia, the patients in the departments of oncology and hematology, infection, pediatrics, obstetrics, gastroenterology, and gynecology were more and accounted for 19. 2%, 11. 78%, 10. 50%, 9. 73%, 8. 71% and 7. 94%, respectively. The ratio of male to female patients with microcytic hypochromic anemia was a-bout 3:2, and that of patients with macrocytic anemia was about 2. 5:1. Conclusions:Serum ferritin decrease is an imperative basis in the diagnosis of iron deficiency anemia, and serum ferritin decrease combined with folic acid or vitamin B12 decrease indicates micro-cytic hypochromic anemia. The detection of folic acid and vitamin B12 is a requisite basis in the diagnosis of megaloblastic anemia.%目的::探讨贫血的实验室指标在贫

    We describe the four most common groups of neonatal anemia and their treatments, with particular emphasis on erythropoietin therapy. The hemolytic anemias include the ABO incompatibility (much more frequent, nowadays, than the Rh incompatibility, which has nearly disappeared following the use of anti-D immunoglobulin in postpartum Rh-negative mothers), hereditary spherocytosis and G-6-PD deficiency. Among hypoplastic anemias, that caused by Parvovirus B19 predominates, by far, over Diamond-Blackfan anemia, alpha-thalassemia and the rare sideroblastic anemias. "Hemorrhagic" anemias occur during twin-to-twin transfusions, or during feto-maternal transfusions. Finally, the multifactorial anemia of prematurity develops principally as a result of the rapid expansion of the blood volume in this group of patients. Erythropoietin therapy, often at doses much higher than those used in the adult, should be seriously considered in most cases of non-hypoplastic neonatal anemias, to minimise maximally the use of transfusions.

    This study was aimed to investigate the relation of MCL-1 and BAK proteins with incidence and development of nutritional anemia (NA) and their clinical significance. The MCL-1 and BAK protein levels in serum of 66 patients with NA were determined by using ELISA. Eighteen healthy people were randomly selected as normal controls. The results indicated that: (1) as compared with normal control group, the expression level of MCL-1 protein in 3 NA groups (iron-deficiency anemia, macrocytic anemia, mixed anemia) significantly decreased (P < 0.001), while the expression level of BAK protein obviously increased (P < 0.001), but the expression level of MCL-1 and BAK proteins among 3 NA groups showed no obvious differences; (2) the MCL-1 protein expression level increased and BAK protein expression level decreased in 3 NA groups after treatment (P < 0.05). (3) there was negative correlation of expression levels of MCL-1 protein with BAK protein in NA group (r = -0.858 P < 0.05). It is concluded that the MCL-1 and BAK proteins may play an important role in the incidence and development of NA, and can be used as the assist index for defining diagnosis and evaluate prognosis of NA.

    Megaloblastic anemia is one of the acquired nutritional anemias that may complicate pregnancy. It is most often secondary to folic acid deficiency because folate requirements are increased during gestation. When the diagnosis of megaloblastic anemia is confirmed, appropriate therapy will initiate a rapid reversal of the anemia process. Because of the association between neural tube defects and folate deficiency, it is recommended that women of reproductive age take folic acid supplementation.

Patients and methods: Patients diagnosed with incident cancers of breast, lung, colon/rectum, stomach, and ovary who received chemotherapy were identified from Kaiser Permanente Southern California Health Plan (2010–2012. All clinical data were collected from the health plan’s electronic medical records. Incidence proportions of patients developing anemia and 95% confidence intervals were calculated overall and by anemia severity and type, as well as by stage at cancer diagnosis, and by chemotherapy regimen and cycle. Results: A total of 4,426 patients who received chemotherapy were included. Across cancers, 3,962 (89.5% patients developed anemia during the course of chemotherapy (normocytic 85%, macrocytic 10%, microcytic 5%; normochromic 47%, hyperchromic 44%, hypochromic 9%. The anemia grades were distributed as follows: 58% were grade 1, 34% grade 2, 8% grade 3, and <1% grade 4. The incidence of grade 2+ anemia ranged from 26.3% in colorectal cancer patients to 59.2% in ovarian cancer patients. Incidence of grade 2+ anemia increased from 29% in stage I to 49% in stage IV. Incidence of grade 2+ anemia varied from 18.2% in breast cancer patients treated with cyclophosphamide + docetaxel regimen to 59.7% in patients with ovarian cancer receiving carboplatin + paclitaxel regimen. Conclusion: The incidence of moderate-to-severe anemia (hemoglobin <10 g/dL remained considerably

    Vitamin B12 deficiency is a very rare disease of infants and young children in Europe. Authors report a case of a 9.5-month-old infant who was exclusively breast-fed by his vegan mother and developed serious vitamin B12 deficiency in form of neurological regression, repetitive vomiting, drowsiness, dysphagia, obstipation, and tremor. A few days after intramuscular vitamin substitution his abnormal signs improved dramatically, hematological restitution was reached in six weeks. Authors describe the hematological and neurological signs, the diagnostic and differential-diagnostic pitfalls, therapy, prognosis, and prevention of this condition. Beside reviewing the literature they emphasize the importance of early recognition and intervention and the need of an appropriate doctor-parent cooperation in this disease.

    Lahner, Edith; Annibale, Bruno

    2009-11-07

    Pernicious anemia (PA) is a macrocytic anemia that is caused by vitamin B(12) deficiency, as a result of intrinsic factor deficiency. PA is associated with atrophic body gastritis (ABG), whose diagnosis is based on histological confirmation of gastric body atrophy. Serological markers that suggest oxyntic mucosa damage are increased fasting gastrin and decreased pepsinogen I. Without performing Schilling's test, intrinsic factor deficiency may not be proven, and intrinsic factor and parietal cell antibodies are useful surrogate markers of PA, with 73% sensitivity and 100% specificity. PA is mainly considered a disease of the elderly, but younger patients represent about 15% of patients. PA patients may seek medical advice due to symptoms related to anemia, such as weakness and asthenia. Less commonly, the disease is suspected to be caused by dyspepsia. PA is frequently associated with autoimmune thyroid disease (40%) and other autoimmune disorders, such as diabetes mellitus (10%), as part of the autoimmune polyendocrine syndrome. PA is the end-stage of ABG. Long-standing Helicobacter pylori infection probably plays a role in many patients with PA, in whom the active infectious process has been gradually replaced by an autoimmune disease that terminates in a burned-out infection and the irreversible destruction of the gastric body mucosa. Human leucocyte antigen-DR genotypes suggest a role for genetic susceptibility in PA. PA patients should be managed by cobalamin replacement treatment and monitoring for onset of iron deficiency. Moreover, they should be advised about possible gastrointestinal long-term consequences, such as gastric cancer and carcinoids.

    Full Text Available AIM AND OBJECTIVES OF THE STUDY: The present study is aimed at detecting the association of autonomic dysfunction occurs in chronic severe anemia. All patients with hemoglobin less than 6 gm % and symptoms referable to anemia for > 6 months duration were included in the study. Patients with cardiac, hepatic, renal disease, leprosy, hypertension, diabetes mellitus and those on sympathomimetic, parasympatholytic, antihypertensive drugs and also patients below the age of 13 year were excluded from the study. Sample size is 50. RESULTS AND CONCLUSIONS: A total of fifty patients were included in the study. Among them, 20 (40% were males and 30(60% were females with male to female ratio of 1:1.5. majority of the patients were in the age group of 21- 30years with mean age of 33 years. Dimorphic anemia was the most frequent type of anemia in 56% of cases: microcytic hypochromic anemia 42% and macrocytic seen only in 2%. Resting tachycardia of more than 100 per min was observed in 62% cases. Most of the cases (86% had prolonged QTc interval of more than 0.40sec. 44% cases had abnormal valsalva response, 60% had abnormal 30/15 ratio, inspiration and expiration ratio was abnormal in 38% cases, and postural hypotension was observed in 86% cases. Diastolic raise in blood pressure to sustained hand grip was abnormal in 78% cases. Atropine test was abnormal in 26% cases. Two or more autonomic function tests were abnormal in all the cases. All the cases had combined sympathetic and parasympathetic involvement. 42% cases had involvement of afferent limb of parasympathetic reflex arc. The common abnormality found in cases of chronic severe anemia are postural hypotension and abnormal heart rate response to valsalva and standing are due to blunting of carotid body chemoreceptor and baroreceptor indicating of both sympathetic and parasympathetic involvement.

    Full Text Available Iron deficiency anemia (IDA is the most frequent form of anemia in pregnant women. Folic acid, vitamin B12 deficiency, and hemoglobinopathies are other causes of anemia in pregnancy. Finding the underlying cause are crucial to the management of the anemia. Anemia is defined as hemoglobin of <11 g/dl in the first and third trimester and <10.5 g/dl in second trimester. According to the literature, anemia, particularly severe anemia (Hb<7g/dl is associated with increased risk of maternal and perinatal mortality and morbidity, and long term adverse effects in the newborn. The association of hemoglobin levels to perinatal outcome has been shown to be U shaped with both high and low hemoglobin levels being associated adverse perinatal outcome such as low birth weight, increased stillbirths. Anemia in pregnancy is a major public health problem. Ideally a woman should have adequate iron stores when she conceives, in order meet to additional requirements of pregnancy. This review focuses on the occurrence, types, maternal and perinatal outcomes, prevention and treatment of anemia during pregnancy. [Archives Medical Review Journal 2013; 22(3.000: 300-316

    Full Text Available A 43-year-old Hispanic male without significant previous medical history was brought to emergency department for syncope following a blood draw to investigate a 40 lbs weight loss during the past 6 months associated with decreased appetite and progressive fatigue. The patient also reported a 1-month history of jaundice. On examination, he was hemodynamically stable and afebrile with pallor and diffuse jaundice but without skin rash or palpable purpura. Normal sensations and power in all extremities were evident on neurological exam. Presence of hemolytic anemia, schistocytosis, thrombocytopenia, and elevated lactate dehydrogenase (LDH was suggestive of thrombotic thrombocytopenic purpura (TTP. However, presence of leukopenia, macrocytes, and an inadequate reticulocyte response to the degree of anemia served as initial clues to an alternative diagnosis. Two and one units of packed red blood cells were transfused on day 1 and day 3, respectively. In addition, one unit of platelets was transfused on day 2. Daily therapeutic plasma exchange (TPE was initiated and continued until ADAMTS-13 result ruled out TTP. A low cobalamin (vitamin B12 level was evident at initial laboratory work-up and subsequent testing revealed positive intrinsic factor-blocking antibodies supporting a diagnosis of pernicious anemia with severe cobalamin deficiency. Hematological improvement was observed following vitamin B12 supplementation. The patient was discharged and markedly improved on day 9 with outpatient follow-up for cobalamin supplementation.

    Fanconi anemia is a rare inherited disease characterized by congenital anomalies, growth retardation, aplastic anemia and an increased risk of acute myeloid leukemia and squamous cell carcinomas. The disease is caused by mutation in genes encoding proteins required for the Fanconi anemia pathway, a response mechanism to replicative stress, including that caused by genotoxins that cause DNA interstrand crosslinks. Defects in the Fanconi anemia pathway lead to genomic instability and apoptosis of proliferating cells. To date, 13 complementation groups of Fanconi anemia were identified. Five of these genes have been deleted or mutated in the mouse, as well as a sixth key regulatory gene, to create mouse models of Fanconi anemia. This review summarizes the phenotype of each of the Fanconi anemia mouse models and highlights how genetic and interventional studies using the strains have yielded novel insight into therapeutic strategies for Fanconi anemia and into how the Fanconi anemia pathway protects against genomic instability.

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    A 57-year-old man consulted a local hospital because of a persistent slight fever. At the age of 37 years he was diagnosed having B-type hepatitis, but left the liver dysfunction untreated. Twenty years later, he was diagnosed having chronic hepatitis B, hepatocellular carcinoma (HCC) and macrocytic anemia, and referred to our hospital for further investigation. A HCC with a maximum diameter of 5.2 cm was detected in segment 8. Results of blood tests included 1.8 mg/dL serum total bilirubin, 0.9 mg/dL bilirubin, less than 10 mg/dL haptoglobin, 7.9 g/dL hemoglobin, 130 fL MCV, and 14.5% reticulocytes. A bone marrow sample showed erythroid hyperplasia. The direct Coombs test gave a positive result. We diagnosed the anemia as autoimmmune hemolytic anemia (AIHA), for which prednisolone could not be administered due to positivity for HBsAg and HBeAg. After preparation of washed blood cells for later transfusion, the patient underwent systematic resection of segment 8. The cut surface of the resected specimen demonstrated an encapsulated yellow-brownish tumor measuring 52 mm × 40 mmwhich was diagnosed pathologicaly as moderately differentiated HCC. On the 9th postoperative day, the patient's temperature rose to 38℃, and exacerbated hemolysis was observed. The maximum total bilirubin value was 5.8 mg/dL and minimum hemoglobin level was 4.6 g/dL. He tolerated this period without blood transfusion. Currently he is being followed up as an outpatient, and shows no signs of HCC recurrence or symptoms of anemia. AIHA associated with HBV infection has been described in only three previous cases, and the present case is the first in which surgery was performed for accompanying HCC.

    In order to explore the diagnosis and therapy of Diamond Blackfan anemia (DBA), the clinical data of 45 cases of DBA admitted in our hospital from February 1994 to July 2011 were analyzed retrospectively. The clinical characteristics, results of laboratory examination, treatment reaction and outcome of disease were investigated. The results indicated that out of 45 children diagnosed as DBA, 14 cases (31.1%) had short stature and physical malformation. All patients had anemia with reticulocytopenia. Thirty-four patients (75.6%) had mean corpuscular volume. Eleven patients (24.4%) had macrocytic anemia. Bone marrow examination showed a marked erythroid hypoplasia in all patients. Out of 29 cases tested for fetal hemoglobin (HbF), 13 cases (44.8%) had high level of HbF. Erythroid colony-forming unit of bone marrow was tested in 25 patients, among them 12 patients (48%) showed normal plasia, 13 (52%) showed hypoplasia. The erythropoietin (EPO) levels of 17 patients were elevated. Karyotypes were examined in 28 patients, and showed all normal. The treatment was based on corticosteroids and Cyclosporine A. Thirty patients had good response to corticosteroid therapy, and 10 of them obtained a sustained corticosteroid-induced remission. Twenty cases discontinued corticosteroid therapy after remission, as a result, 15 cases (75%) relapsed, moreover all the relapsed cases still had good response to corticosteroid. Two relapsed patients suffered from aplastic anemia, one of them died of therapy failure. Six patients were unresponsive to corticosteroid, 1 of which achieved remission with cyclosporine A and the others continued to receive regular transfusions. 3 patients received iron chelation therapy. It is concluded that the clinical characteristics, complete blood count, bone marrow smear, HbF level and EPO level are useful to make a diagnosis of DBA. Most patients have a good response to corticosteroid therapy, but relapse rate is high when drug was discontinued. Patients

    Red blood cells (RBC) must coordinate their rate of growth and proliferation with the availability of nutrients, such as iron, but the signaling mechanisms that link the nutritional state to RBC growth are incompletely understood. We performed a screen for cell types that have high levels of signaling through mTORC1, a protein kinase that couples nutrient availability to cell growth. This screen revealed that reticulocytes show high levels of phosphorylated ribosomal protein S6, a downstream target of mTORC1. We found that mTORC1 activity in RBCs is regulated by dietary iron and that genetic activation or inhibition of mTORC1 results in macrocytic or microcytic anemia, respectively. Finally, ATP competitive mTOR inhibitors reduced RBC proliferation and were lethal after treatment with phenylhydrazine, an inducer of hemolysis. These results identify the mTORC1 pathway as a critical regulator of RBC growth and proliferation and establish that perturbations in this pathway result in anemia.

  1. Dysferlin and other non-red cell proteins accumulate in the red cell membrane of Diamond-Blackfan Anemia patients.

    Directory of Open Access Journals (Sweden)

    Esther N Pesciotta

    Full Text Available Diamond Blackfan Anemia (DBA is a congenital anemia usually caused by diverse mutations in ribosomal proteins. Although the genetics of DBA are well characterized, the mechanisms that lead to macrocytic anemia remain unclear. We systematically analyzed the proteomes of red blood cell membranes from multiple DBA patients to determine whether abnormalities in protein translation or erythropoiesis contribute to the observed macrocytosis or alterations in the mature red blood cell membrane. In depth proteome analysis of red cell membranes enabled highly reproducible identification and quantitative comparisons of 1100 or more proteins. These comparisons revealed clear differences between red cell membrane proteomes in DBA patients and healthy controls that were consistent across DBA patients with different ribosomal gene mutations. Proteins exhibiting changes in abundance included those known to be increased in DBA such as fetal hemoglobin and a number of proteins not normally found in mature red cell membranes, including proteins involved in the major histocompatibility complex class I pathway. Most striking was the presence of dysferlin in the red blood cell membranes of DBA patients but absent in healthy controls. Immunoblot validation using red cell membranes isolated from additional DBA patients and healthy controls confirmed a distinct membrane protein signature specific to patients with DBA.

  2. Megaloblastic anemia in Japan

    Full Text Available Since 1903, 744 cases of megaloblastic anemia have been reported in Japan: 490 cases of pernicious anemia; 95 cases associated with pregnancy; 66 cases after gastrectomy; 22 cases of megaloblastic anemia of infants; 21 cases of folic acid deficiency other than pregnancy and 19 cases of vitamin B12 malabsorption after ileal resection. It is generally agreed among hematologists in Japan that pernicious anemia is relatively rare, as in other Asian countries. The diagnosis of pernicious anemia in Japan is usually made by stained marrow films, radioisotopic assay of serum vitamin B12, Schilling test and good response to vitamin B12 therapy. Serum folate level, intrinsic factor or its antibody, methylmalonic acid excretion, formiminoglutamic acid excretion and deoxyuridine suppression test are performed only at a small number of laboratories. The drugs of choice are hydroxocobalamin, deoxyadenosylcobalamin and methylcobalamin. Cyanocobalamin has nearly disappeared from commercial sources in Japan. Vitamin B12 administration is common in patients with neurological disorders. Megaloblastic anemia due to folic acid deficiency is extremely rare in Japan. Low serum folate levels are frequently observed among patients receiving anticonvulsants or in pregnant women, but in such samples megaloblastic anemia is almost never detected. The folic acid content of hospital diets indicates that satisfactory amounts of folate are taken in Japan. The intake of folic acid from rice is well over the minimum daily requirement of folate. Other factors in folic acid deficiency, such as food taboos, severe alcoholism and malabsorption syndrome are not frequently found in Japanese. The inadequate intake of folate was the critical factor in most reported cases.

    Anaemia is a problem that affects almost 10% over 65 years and 20% over 85 years. There is no physiological anaemia in the elderly. Any anaemia expresses the existence of a pathological process, regardless of its severity. Anaemia in the elderly is always associated with a poor prognosis that is in terms of mortality, morbidity and risk of fragility. The diagnostic approach to anemia in the elderly is the same as in younger individual. There are many causes of anaemia; anaemia balance is a complex diagnostic process. Most anaemias are due to a deficiency, chronic inflammation or comorbidity. However, in the elderly, the etiology of anaemia is often multifactorial. In a number of cases remain unexplained anaemia. In a number of cases, anemia remain unexplained. Treatment of anaemia is the treatment of the cause, but specific therapeutic aspects to the elderly should be considered, as among other martial substitution or use of erythropoietin (EPO).

    Anemia is the most frequent derailment of physiology in the world throughout the life of a woman. It is a serious condition in countries that are industrialized and in countries with poor resources. The main purpose of this manuscript is to give the right concern of anemia in pregnancy. The most common causes of anemia are poor nutrition, iron deficiencies, micronutrients deficiencies including folic acid, vitamin A and vitamin B12, diseases like malaria, hookworm infestation and schistosomiasis, HIV infection and genetically inherited hemoglobinopathies such as thalassemia. Depending on the severity and duration of anemia and the stage of gestation, there could be different adverse effects including low birth weight and preterm delivery. Treatment of mild anemia prevents more severe forms of anemia, strictly associated with increased risk of fetal-maternal mortality and morbidity.

    2015-01-01

    The anemia of chronic disease is an old disease concept, but contemporary research in the role of proinflammatory cytokines and iron biology has shed new light on the pathophysiology of the condition. Recent epidemiologic studies have connected the anemia of chronic disease with critical illness, obesity, aging, and kidney failure, as well as with the well-established associations of cancer, chronic infection, and autoimmune disease. Functional iron deficiency, mediated principally by the interaction of interleukin-6, the iron regulatory hormone hepcidin, and the iron exporter ferroportin, is a major contributor to the anemia of chronic disease. Although anemia is associated with adverse outcomes, experimental models suggest that iron sequestration is desirable in the setting of severe infection. Experimental therapeutic approaches targeting interleukin-6 or the ferroportin-hepcidin axis have shown efficacy in reversing anemia in either animal models or human patients, although these agents have not yet been approved for the treatment of the anemia of chronic disease.

    The development of recombinant human erythropoietin and its introduction into the market in the late 1980s has significantly improved the quality of life of patients with chronic kidney disease (CKD) and reduced the need for blood transfusions. Starting from a cautious target, a progressive increase in the recommended hemoglobin levels has been observed over the years, in parallel with an increase in the obtained levels. This trend has gone together with the publication of findings of observational studies showing a relationship between the increase in hemoglobin levels and a reduction in the mortality risk, with the conduction of clinical trials testing the effects of complete anemia correction, and with the compilation of guidelines on anemia control in CKD patients by scientific societies and organizations. In the last two years, evidence of a possible increase in the mortality risk in those patients who were randomized to high hemoglobin levels has resulted in a decrease in the upper limit of the recommended Hb target to be obtained with erythropoietin stimulating agents (ESA), and consequently in a narrowing of the target range. Comparison of guidelines on anemia control in CKD patients is an interesting starting point to discuss single recommendations, strengthen their importance, or suggest new topics of research to fill up important gaps in knowledge.

    Anemia is a common problem in obstetrics and perinatal care. Any hemoglobin below 10.5 g/dL can be regarded as true anemia regardless of gestational age. Reasons for anemia in pregnancy are mainly nutritional deficiencies, parasitic and bacterial diseases, and inborn red blood cell disorders such as thalassemias. The main cause of anemia in obstetrics is iron deficiency, which has a worldwide prevalence between estimated 20%-80% and consists of a primarily female population. Stages of iron deficiency are depletion of iron stores, iron-deficient erythropoiesis without anemia, and iron deficiency anemia, the most pronounced form of iron deficiency. Pregnancy anemia can be aggravated by various conditions such as uterine or placental bleedings, gastrointestinal bleedings, and peripartum blood loss. In addition to the general consequences of anemia, there are specific risks during pregnancy for the mother and the fetus such as intrauterine growth retardation, prematurity, feto-placental miss ratio, and higher risk for peripartum blood transfusion. Besides the importance of prophylaxis of iron deficiency, the main therapy options for the treatment of pregnancy anemia are oral iron and intravenous iron preparations.

  13. Mice with ribosomal protein S19 deficiency develop bone marrow failure and symptoms like patients with Diamond-Blackfan anemia.

    2011-12-01

    Diamond-Blackfan anemia (DBA) is a congenital erythroid hypoplasia caused by a functional haploinsufficiency of genes encoding for ribosomal proteins. Among these genes, ribosomal protein S19 (RPS19) is mutated most frequently. Generation of animal models for diseases like DBA is challenging because the phenotype is highly dependent on the level of RPS19 down-regulation. We report the generation of mouse models for RPS19-deficient DBA using transgenic RNA interference that allows an inducible and graded down-regulation of Rps19. Rps19-deficient mice develop a macrocytic anemia together with leukocytopenia and variable platelet count that with time leads to the exhaustion of hematopoietic stem cells and bone marrow failure. Both RPS19 gene transfer and the loss of p53 rescue the DBA phenotype implying the potential of the models for testing novel therapies. This study demonstrates the feasibility of transgenic RNA interference to generate mouse models for human diseases caused by haploinsufficient expression of a gene.

    Mitochondrial myopathy with lactic acidosis and sideroblastic anemia (MLASA) is an oxidative phosphorylation disorder, with primary clinical manifestations of myopathic exercise intolerance and a macrocytic sideroblastic anemia. One cause of MLASA is recessive mutations in PUS1, which encodes pseudouridine (Ψ) synthase 1 (Pus1p). Here we describe a mouse model of MLASA due to mutations in PUS1. As expected, certain Ψ modifications were missing in cytoplasmic and mitochondrial tRNAs from Pus1−/− animals. Pus1−/− mice were born at the expected Mendelian frequency and were non-dysmorphic. At 14 weeks the mutants displayed reduced exercise capacity. Examination of tibialis anterior (TA) muscle morphology and histochemistry demonstrated an increase in the cross sectional area and proportion of myosin heavy chain (MHC) IIB and low succinate dehydrogenase (SDH) expressing myofibers, without a change in the size of MHC IIA positive or high SDH myofibers. Cytochrome c oxidase activity was significantly reduced in extracts from red gastrocnemius muscle from Pus1−/− mice. Transmission electron microscopy on red gastrocnemius muscle demonstrated that Pus1−/− mice also had lower intermyofibrillar mitochondrial density and smaller mitochondria. Collectively, these results suggest that alterations in muscle metabolism related to mitochondrial content and oxidative capacity may account for the reduced exercise capacity in Pus1−/− mice.

  15. Ceruloplasmin levels and erythrocyte superoxide dismutase activity in small preterm infants during the early anemia of prematurity.

    Science.gov (United States)

    Hågå, P

    1981-11-01

    Ceruloplasmin plasma levels and erythrocyte superoxide dismutase activity were studied in appropriate for gestational age preterm infants (birth weights less than or equal to 1500 g) during the first 10 weeks of life. Preterm infants had significantly lower ceruloplasmin concentrations in cord blood than term infants, the mean level in the preterm infants being 0.07 g/l. At 1 week of age ceruloplasmin levels had risen significantly, whereupon a fall occurred at 2 weeks of age. Ceruloplasmin concentrations increased slowly and progressively from 4 weeks of age. The low ceruloplasmin concentration during the early anemia of prematurity seems not to interfere with iron mobilization. The superoxide dismutase activity per gram hemoglobin in cord blood erythrocytes from normal term infants was significantly lower than that of red blood cells from adults. When the activity was expressed per erythrocyte no difference was found. The normochromic macrocytic red blood cells of the neonate most likely explain this discrepancy. The erythrocyte superoxide dismutase activity of the preterm infants did not change from birth until 10 weeks of age, and the levels seemed adequate judged from the levels found in red blood cells from adults and cord blood from term infants.

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Anemia is a form of blood disorder most often occurs in the community. Sickle cell anemia is anemia due to hemoglobinopathy caused by a change in the amino acid-6 of the ? globin chain. Sickle cell anemia is common in tropical areas of Africa and some parts of the region Saudi Arabia, India and the Mediterranean as well as black people in America. In addition there are also careers in various European countries. In pathophysiology, there are amino acid change from glutamic acid to valine in the ?-globin chain that causes red blood cells become sickle-shaped when deoxygenatied, but still be able to return to its normal shape when experiencing oxygenation. When the red blood cell membrane have been amended, the polymerization of red blood cells has become irreversible. Clinical picture seen in sickle cell anemia can be divided into two, namely: acute and chronic. Diagnosis can be done is to distinguish between heterozygous or homozygous sickle cell. Treatment provided in accordance with the clinical picture appears. Treatment that can be done is by blood transfusion, bone marrow transplant, anti-sickling drug delivery, and drug delivery to trigger the synthesis of HbF. Treatment still in the development stage is to use stem cells. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

    Warm autoimmune hemolytic anemia (AIHA) is defined as the destruction of circulating red blood cells (RBCs) in the setting of anti-RBC autoantibodies that optimally react at 37°C. The pathophysiology of disease involves phagocytosis of autoantibody-coated RBCs in the spleen and complement-mediated hemolysis. Thus far, treatment is aimed at decreasing autoantibody production with immunosuppression or reducing phagocytosis of affected cells in the spleen. The role of complement inhibitors in warm AIHA has not been explored. This article addresses the diagnosis, etiology, and treatment of warm AIHA and highlights the role of complement in disease pathology.

  1. Complement in hemolytic anemia.

    Science.gov (United States)

    Brodsky, Robert A

    2015-01-01

    Complement is increasingly being recognized as an important driver of human disease, including many hemolytic anemias. Paroxysmal nocturnal hemoglobinuria (PNH) cells are susceptible to hemolysis because of a loss of the complement regulatory proteins CD59 and CD55. Patients with atypical hemolytic uremic syndrome (aHUS) develop a thrombotic microangiopathy (TMA) that in most cases is attributable to mutations that lead to activation of the alternative pathway of complement. For optimal therapy, it is critical, but often difficult, to distinguish aHUS from other TMAs, such as thrombotic thrombocytopenic purpura; however, novel bioassays are being developed. In cold agglutinin disease (CAD), immunoglobulin M autoantibodies fix complement on the surface of red cells, resulting in extravascular hemolysis by the reticuloendothelial system. Drugs that inhibit complement activation are increasingly being used to treat these diseases. This article discusses the pathophysiology, diagnosis, and therapy for PNH, aHUS, and CAD.

    Full Text Available BACKGROUND: Sickle cell disease, the most common hereditary blood disease in the world, is the result of an atypical hemoglobin called S (Hb S which, when homozygous (Hb SS is the cause of sickle cell anemia. Changes of puberty, correlated with a delayed growth spurt, begin late in both male and female sickle cell anemia individuals with repercussions on sexuality and reproduction. The objectives of this exploratory and descriptive study were to characterize the development of sexuality in adults with sickle cell anemia by investigating the patient's perception of their sex life, as well as the information they had and needed on this subject. METHODS: Twenty male and female sickle cell anemia patients treated at the Hemocentro Regional de Uberaba (UFTM with ages between 19 and 47 years old were enrolled. A socioeconomic questionnaire and a semi-structured interview on sexuality, reproduction and genetic counseling were applied. RESULTS: This study shows that the sickle cell anemia patients lacked information on sexuality especially about the risks of pregnancy and the possible inheritance of the disease by their children. Moreover, the sexual life of the patients was impaired due to pain as well as discrimination and negative feelings experienced in close relationships. CONCLUSION: The health care of sickle cell anemia patients should take into account not only the clinical aspects of the disease, but also psychosocial aspects by providing counseling on sexuality, reproduction and genetics, in order to give this population the possibility of a better quality of life.

    Full Text Available Anemia é uma complicação comum em pacientes com mieloma múltiplo (MM e ocorre em mais de 2/3 dos pacientes. Anemia de doença crônica, deficiência de eritropoetina (EPO devido à insuficiência renal e efeito mielossupressivo da quimioterapia são os principais mecanismos patofisiológicos que contribuem para o desenvolvimento de anemia no MM. Nos pacientes que obtêm remissão completa com tratamento quimioterápico, anemia usualmente se normaliza. Nos pacientes que não respondem ou apresentam recaída do mieloma, anemia freqüentemente persiste. As opções de tratamento dos pacientes anêmicos com MM incluem transfusões de hemácias e EPO recombinante humana. Essa proteína é biologicamente equivalente à EPO endógena e sua administração promove aumento dos valores de hemoglobina por tempo mais prolongado sem os riscos das transfusões de sangue. Vários estudos têm relatado melhora significante da eritropoese, redução da necessidade transfusional e melhora da qualidade de vida com o uso da EPO como tratamento a longo prazo da anemia associada ao mieloma. Nesse artigo, propomos o tratamento da anemia do MM baseado nas recomendações propostas pela Sociedade Americana de Hematologia (ASH em conjunto com a Sociedade Americana de Oncologia Clínica (ASCO, pela Organização Européia para Pesquisa e Tratamento do Câncer (EORTC, pelo IMF (Internacional Myeloma Foundation e pelo NCCN (National Comprehensive Cancer Network.Anemia is a common complication in patients with multiple myeloma (MM occurring in more than two thirds of all patients.

    Aplastic Fanconi anemia (FA) accompanying malformation was firstly reported in 1927. This review concerns the recent findings on FA. FA belongs to the chromosomal instability syndrome and its detailed molecular mechanism is still unknown. The disease has been defined to be highly sensitive to radiation, however, which is quite an important problem since irradiation with a large dose of radiation is required before its radical treatment (bone marrow transplantation). FA cells are also mitomycin C-sensitive and FA patients are said to be the mosaic of the sensitive and normal cells. This enables to classify FA into 8 types of A-H groups, whose genotypes (FAA-FAH, FANCA-FANCH) are becoming clear. However, the intracellular function of the FANC-expressed protein, although known to form a big complex, is not elucidated yet. There is an abnormality in DNA processing such as re-linkage of the double strand-broken DNA in FA cells. FA causal gene FANCG is found identical to XRCC9 which is associated to high sensitivity to radiation. Analysis of FANC genes will provide useful findings on molecular mechanism of DNA-repair.

    Acute intracerebral hemorrhage (ICH) associated with mild anemia is commonly observed on radiological examination, and there are several reports of ruptured aneurysms occurring with ICH but without accompanying subarachnoid hemorrhage. However, the relationship among computed tomography (CT), magnetic resonance imaging (MRI), and intraoperative findings of ICH caused by ruptured cerebral aneurysm in patients with severe chronic anemia has been rarely reported and is poorly understood. Here, we report atypical radiological and intraoperative findings of acute ICH caused by ruptured cerebral aneurysm in a patient with severe chronic anemia. A 64-year-old man with anemia was admitted to our hospital after he experienced left hemiparesis and a disturbance of consciousness. At a referring institution, he showed evidence of macrocytic anemia (white blood cell count, 9,000/μL; red blood cell count, 104×10(4)/μL; hemoglobin, 4.0 g/dL; hematocrit, 12.2%; and platelet count, 26.6×10(4)/μL). Both CT and MRI showed a right frontal ICH. The outer ring of the hematoma appeared as low-density area on CT, a low-intensity area on T1-weighted MRI, and a high-intensity area on T2-weighted MRI with a serous component. The patient received a blood transfusion and underwent surgical removal of the hematoma the following day. The white serous effusion visualized with CT and MRI was identified as a blood clot in the hematoma cavity. The blood that leaks from blood vessels appears as a high-intensity area on CT because it undergoes plasma absorption in a solidification shrinkage process, and is, therefore, concentrated. Although we did not examine the white effusion to determine if serous components were present, we speculated that the effusion may have contained serous components. Therefore, we removed the part of the effusion that appeared as a low-density area on CT. The presence of ICH without subarachnoid hemorrhage suggested the possible adhesion and rupture of a previous

    Iron deficiency is not just anemia; it can be responsible for a long list of other manifestations. This topic is of great importance, especially in infancy and early childhood, for a variety of reasons. Firstly, iron need is maximum in this period. Secondly, diet in infancy is usually deficient in iron. Thirdly and most importantly, iron deficiency at this age can result in neurodevelopmental and cognitive deficits, which may not be reversible. Hypochromia and microcytosis in a complete blood count (CBC) makes iron deficiency anemia (IDA) most likely diagnosis. Absence of response to iron should make us look for other differential diagnosis like β thalassemia trait and anemia of chronic disease. Celiac disease is the most important cause of true IDA not responding to oral iron therapy. While oral ferrous sulphate is the cheapest and most effective therapy for IDA, simple nonpharmacological and pharmacological measures can go a long way in prevention of iron deficiency.

    Patients with physical findings suggestive of Treacher Collins syndrome (TCS) or mandibulofacial dysostosis (MFD) and macrocytic anemia diagnostic of Diamond-Blackfan anemia (DBA) have been reported. Disease-causing genes have been identified for TCS and other MFDs. Mutations in several ribosomal protein genes and the transcription factor GATA1 result in DBA. However, no disease-causing mutation had been identified in the reported patients with the combination of TCS/MFD and DBA phenotype, and we hypothesized that pathogenic mutations in a single gene could be identified using whole exome analysis. We studied probands from six unrelated families. Combining exome analysis and Sanger sequencing, we identified likely pathogenic mutations in 5/6 families. Two mutations in unrelated families were seen in RPS26, the known DBA10 gene. One variant was predicted to affect mRNA splicing, and the other to lead to protein truncation. In another family a likely pathogenic X-linked mutation affecting a highly conserved residue was found in TSR2, which encodes a direct binding partner of RPS26. De novo mutations affecting the RPS28 start codon were found in two unrelated probands, identifying RPS28 as a novel disease gene. We conclude that the phenotype combining features of TCS with DBA is genetically heterogeneous. Each of the pathogenic variants identified is predicted to impede ribosome biogenesis, which in turn could result in altered cell growth and proliferation, causing abnormal embryologic development, defective erythropoiesis and reduced growth. The phenotype combining TCS/MFD and DBA is highly variable, overlaps with DBA and lies within the phenotypic spectrum of ribosomopathies. © 2014 Wiley Periodicals, Inc.

    Harigae, Hideo; Furuyama, Kazumichi

    2010-10-01

    Sideroblastic anemia is characterized by anemia with the emergence of ring sideroblasts in the bone marrow. Ring sideroblasts are erythroblasts characterized by iron accumulation in perinuclear mitochondria due to impaired iron utilization. There are two forms of sideroblastic anemia, i.e., inherited and acquired sideroblastic anemia. Inherited sideroblastic anemia is a rare and heterogeneous disease caused by mutations of genes involved in heme biosynthesis, iron-sulfur (Fe-S) cluster biogenesis, or Fe-S cluster transport, and mitochondrial metabolism. The most common inherited sideroblastic anemia is X-linked sideroblastic anemia (XLSA) caused by mutations of the erythroid-specific δ-aminolevulinate synthase gene (ALAS2), which is the first enzyme of heme biosynthesis in erythroid cells. Sideroblastic anemia due to SLC25A38 gene mutations, which is a mitochondrial transporter, is the next most common inherited sideroblastic anemia. Other forms of inherited sideroblastic anemia are very rare, and accompanied by impaired function of organs other than hematopoietic tissue, such as the nervous system, muscle, or exocrine glands due to impaired mitochondrial metabolism. Moreover, there are still significant numbers of cases with genetically undefined inherited sideroblastic anemia. Molecular analysis of these cases will contribute not only to the development of effective treatment, but also to the understanding of mitochondrial iron metabolism.

    2015-01-01

    Anemia affects one-fourth of the world’s population, and iron deficiency is the predominant cause. Anemia is associated with chronic fatigue, impaired cognitive function, and diminished well-being. Patients with iron deficiency anemia of unknown etiology are frequently referred to a gastroenterologist because in the majority of cases the condition has a gastrointestinal origin. Proper management improves quality of life, alleviates the symptoms of iron deficiency, and reduces the need for blood transfusions. Treatment options include oral and intravenous iron therapy; however, the efficacy of oral iron is limited in certain gastrointestinal conditions, such as inflammatory bowel disease, celiac disease, and autoimmune gastritis. This article provides a critical summary of the diagnosis and treatment of iron deficiency anemia. In addition, it includes a management algorithm that can help the clinician determine which patients are in need of further gastrointestinal evaluation. This facilitates the identification and treatment of the underlying condition and avoids the unnecessary use of invasive methods and their associated risks. PMID:27099596

  14. Comparative Assessment of Vitamin-B12, Folic Acid and Homocysteine Levels in Relation to p53 Expression in Megaloblastic Anemia

    Science.gov (United States)

    Yadav, Manish K.; Manoli, Nandini M.

    2016-01-01

    Background Megaloblastic anemia (MBA), also known as macrocytic anemia, is a type of anemia characterized by decreased number of RBCs as well as the presence of unusually large, abnormal and poorly developed erythrocytes (megaloblasts), which fail to enter blood circulation due to their larger size. Lack of vitamin-B12 (VB12) and / or folate (Vitamin-B9, VB9) with elevated homocysteine is the key factor responsible for megaloblastic anemia. Prior studies have demonstrated the induction of apoptosis in these abnormal under-developed erythrocytes. However, it is not clear whether this apoptosis induction is due to elevated p53 level or due to any other mechanism. Furthermore, it is also not fully known whether decreased vitamin-B12 and / or folate are responsible for apoptosis induction mediated by p53 in pre-erythroblasts. Methods Levels of serum VB9, VB12 and homocysteine in 50 patients suffering from MBA were compared with 50 non-megaloblastic anemia control subjects, who were referred by the clinicians for bone marrow examination for medical conditions other than MBA. Next, we have measured the p53 expression in the paraffin embedded blocks prepared from bone marrow biopsy, using immunohistochemistry, and the expression levels correlated with VB9 and VB12 levels. Results Out of 50 MBA patients 40 (80%) and 44 (88%) subjects had very low VB12 and VB9 levels respectively. In contrast, only 2 (4%) and 12 (24%) non-megaloblastic anemia controls, out of 50 subjects, had low VB12 and VB9 respectively. Correlating with low vitamin B9 and B12, the homocysteine levels were high in 80% cases. But, only 20% non-megaloblastic controls exhibited high homocysteine in plasma. Immunohistochemical analysis for p53 expression showed a significantly high level of expression in MBA cases and no—or very low—expression in control subjects. Our correlation studies comparing the VB12 and VB9 levels with p53 expression concludes unusually high p53 levels in patients suffering from VB

    Full Text Available A normocytic normochromic anemia is one of the first signs of renal failure. Since anemia increases morbidity and mortality, its elimination is one of the essential objectives of the treatment. Human recombinant erythropoietin (rHuEPO has changed the therapeutical approach to anemia. The aim of the present study was to compare efficacy of anemia correction in peritoneal dialysis patients depending on treatment and dialysis modality. The study is the retrospective analysis of 64 patients who presented to our Clinic in 2003. Eighteen (28.13% patients were treated with rHuEPO, 14 (28% underwent continuous ambulatory peritoneal dialysis (CAPD, 2 (100% - automated peritoneal dialysis (APD and 2 (33.3% - intermittent peritoneal dialysis (IPD. Mean hemoglobin level was 98.6±17.82 g/l in patients treated with rHuEPO versus 98.81±15.14 g/I in patients without rHuEPO treatment. Erythropoietin requirements were 3392.85±1211.77 IU/week. AII patients received iron supplementation during rHuEPO therapy. Mean serum ferritin levels were 463.41 ±360 μg/l. Transferrin saturation (TSAT was 0.35±0.16%. No difference of serum iron and TSAT levels was found between CAPD and IPD patients. The degree of anemia significantly differed between CAPD and IPD patients. A total of 17.11% of PD patients were given blood transfusions, most frequently during the first three months after the onset of dialysis. Our conclusion is that the number of patients receiving rHuEPO should be increased, as 50% of our patients should be substituted, while only 28% are being treated. As 50% of patients receiving rHuEPO failed to reach target Hgb levels, higher EPO doses should be considered. Iron stores should be continuously monitored, particularly in patients receiving rHuEPO, since iron deficiency is an important problem for patients undergoing peritoneal dialysis, especially during erythropoietin therapy. Oral iron supplementation is satisfactory in the majority of patients, and

    Science.gov (United States)

    Wahle, M

    2012-12-01

    One of the most frequent extra-articular organ manifestations in rheumatoid arthritis (RA) is anemia. As anemia in RA patients may result in severe symptoms and aggravation of other disease manifestations (e.g. arteriosclerosis), the influence on the course of RA is profound. However, the importance of anemia in RA patients is frequently underestimated. The etiology of anemia in RA is complex. Anemia of inflammation (AI) and iron deficiency anemia, alone or in combination are the most frequent forms of anemia in RA. Changes in iron metabolism are the leading causes of anemia in RA patients and mainly induced by the altered synthesis and function of hepcidin and ferroportin. Hepcidin, a peptide produced in the liver and immunocompetent cells, impairs the expression of ferroportin on iron-secreting cells, thus reducing iron bioavailability. The typical changes of iron metabolism and hepcidin synthesis in RA are induced by proinflammatory cytokines, primarily interleukin-6. Hence, the treatment of RA with cytokine antagonists has significant therapeutic implications on anemia in the context of inflammation and impaired iron metabolism.

    We conducted a cross sectional study to investigate risk factors associated with severe anemia [hemoglobin (Hb) iron status among Nepali pregnant women. Socio-demographic, anthropometric, health and dietary data were collected from 3,531 women living in the southeastern plains of Nepal. Stool samples were analyzed for intestinal helminthes. Dark adaptation was assessed using the Night Vision Threshold Test (NVTT). Hb levels were measured in all subjects to detect anemia and the soluble transferrin receptor (sTfR) was measured among a subsample of 479 women. The iron status categories were: 1) normal (Hb> or = 11.0 g/dl and sTfR anemia without iron deficiency (Hbiron deficiency without anemia (Hb > or = 11.0 g/dl and sTfR>8.5 mg/l); and 4) iron deficiency anemia (IDA): (Hb8.5 mg/l). Factors associated with severe anemia and poor iron status were determined using logistic regression. Hookworm infection increased the risk for developing severe anemia [adjusted odds ratio (AOR): 4.26; 95% CI 1.67-10.89; piron deficiency with and without anemia. Intake of iron supplements as tablets and/or tonic was protective against severe anemia, anemia without iron deficiency and IDA. Dietary heme iron was significantly associated with iron deficiency without anemia (RRR: 0.1; 95% CI 0.02-0.47; panemia and associated nutrient deficiencies.

    Anaemia is particularly common amongthe elderly population. It is necessary, with the aid of the mean glomerular volume, to determine if it is microcytic, normocytic or macrocytic. Similarly, the level of reticulocytes indicates whether the anaemia is regenerative or non-regenerative. A systematic approach helps to identify the causes of this low haemoglobin level. As always in the elderly, it is necessary to be aware of their inflammatory status and estimate the iatrogenic risk.

  8. Unexplained Aspects of Anemia of Inflammation

    Directory of Open Access Journals (Sweden)

    Elizabeth A. Price

    2010-01-01

    Full Text Available Anemia of inflammation (AI, also known as anemia of chronic inflammation or anemia of chronic disease was described over 50 years ago as anemia in association with clinically overt inflammatory disease, and the findings of low plasma iron, decreased bone marrow sideroblasts and increased reticuloendothelial iron. Pathogenic features underlying AI include a mild shortening of red cell survival, impaired erythropoietin production, blunted responsiveness of the marrow to erythropoietin, and impaired iron metabolism mediated by inflammatory cytokines and the iron regulatory peptide, hepcidin. Despite marked recent advances in understanding AI, gaps remain, including understanding of the pathogenesis of AI associated with “noninflammatory” or mildly inflammatory diseases, the challenge of excluding iron deficiency anemia in the context of concomitant inflammation, and understanding more precisely the contributory role of hepcidin in the development of AI in human inflammatory diseases.

    2016-05-01

    Anemia coexists with inflammatory bowel disease (IBD) in up to two-thirds of patients, significantly impairing quality of life. The most common types of anemia in patients with IBD are iron deficiency anemia and anemia of chronic disease, which often overlap. In most cases, available laboratory tests allow successful diagnosis of iron deficiency, where difficulties appear, recently established indices such as soluble transferrin-ferritin ratio or percentage of hypochromic red cells are used. In this review, we discuss the management of the most common types of anemia in respect of the latest available data. Thus, we provide the mechanisms underlying pathophysiology of these entities; furthermore, we discuss the role of hepcidin in developing anemia in IBD. Next, we present the treatment options for each type of anemia and highlight the importance of individual choice of action. We also focus on newly developed intravenous iron preparations and novel, promising drug candidates targeting hepcidin. Concurrently, we talk about difficulties in differentiating between the true and functional iron deficiency, and discuss tools facilitating the process. Finally, we emphasize the importance of proper diagnosis and treatment of anemia in IBD. We conclude that management of anemia in patients with IBD is tricky, and appropriate screening of patients regarding anemia is substantial.

  10. In-Depth, Label-Free Analysis of the Erythrocyte Cytoplasmic Proteome in Diamond Blackfan Anemia Identifies a Unique Inflammatory Signature.

    Directory of Open Access Journals (Sweden)

    Esther N Pesciotta

    Full Text Available Diamond Blackfan Anemia (DBA is a rare, congenital erythrocyte aplasia that is usually caused by haploinsufficiency of ribosomal proteins due to diverse mutations in one of several ribosomal genes. A striking feature of this disease is that a range of different mutations in ribosomal proteins results in similar disease phenotypes primarily characterized by erythrocyte abnormalities and macrocytic anemia, while most other cell types in the body are minimally affected. Previously, we analyzed the erythrocyte membrane proteomes of several DBA patients and identified several proteins that are not typically associated with this cell type and that suggested inflammatory mechanisms contribute to the pathogenesis of DBA. In this study, we evaluated the erythrocyte cytosolic proteome of DBA patients through in-depth analysis of hemoglobin-depleted erythrocyte cytosols. Simple, reproducible, hemoglobin depletion using nickel columns enabled in-depth analysis of over 1000 cytosolic erythrocyte proteins with only moderate total analysis time per proteome. Label-free quantitation and statistical analysis identified 29 proteins with significantly altered abundance levels in DBA patients compared to matched healthy control donors. Proteins that were significantly increased in DBA erythrocyte cytoplasms included three proteasome subunit beta proteins that make up the immunoproteasome and proteins induced by interferon-γ such as n-myc interactor and interferon-induced 35 kDa protein [NMI and IFI35 respectively]. Pathway analysis confirmed the presence of an inflammatory signature in erythrocytes of DBA patients and predicted key upstream regulators including mitogen activated kinase 1, interferon-γ, tumor suppressor p53, and tumor necrosis factor. These results show that erythrocytes in DBA patients are intrinsically different from those in healthy controls which may be due to an inflammatory response resulting from the inherent molecular defect of ribosomal

    Full Text Available Introduction. The problem of anemia in congestive heart failure and chronic kidney disease was thought to be insignificant for a long period of time. Recent investigations pointed out that the problem of anemia should be defined in the context of the cardio-renal anemia syndrome. A positive feedback mechanism indicates that cardio-renal anemia syndrome is due to an interaction between congestive heart failure, chronic renal failure and anemia. The aim of the study was to present the possible pathophysiological mechanisms of this syndrome, epidemiological characteristics and therapeutic results of the former investigations. Results. The results of the retrospective and prospective controlled trails have shown that management of anemia with subcutaneous administration of recombinant human erythropoietin together with intravenous iron infusion for at least 3-6 months lead to: relief of symptoms (improved NYHA functional class; increased left ventricular ejection fraction; reduced cardiovascular morbidity and mortality; reduced number of rehospitalizations; reduced requirements for usual therapeutic agents (especially diuretics; and improved renal function. Conclusion. In patients with heart and kidney disease anemia should be routinely identified and appropriately treated. Subcutaneous recombinant erythropoietin and intravenous iron may significantly improve overall survival and quality of life of these patients. .

    Iron-deficiency anemia is the most common anemia in infants. In the routine pediatric care this problem is encountered every day. Numerous factors in infancy (low birth weight, rapid growth, insufficient nutrition) are involved in the development of iron-deficiency anemia, and they must be considered when establishing diagnosis, counselling parents, and prescribing oral iron preparations. Data on 119 patients aged up to two years treated in the Division of Gastroenterology and Nutrition, Pediatric Department, University Hospital Centre Zagreb Salata between 1994 and 1999, were analyzed. We were prompted to do so because of great frequency of iron-deficiency anemia as one of associated diagnoses, and unfortunately often the only diagnosis requiring hospitalization. Out of 119 patients with iron-deficiency anemia, nine (7.7%) patients (four premature newborns and three from twin pregnancy) had to receive transfusion of erythrocyte concentrate due to very bad general condition and low red blood count, accompanied by clinical signs of anemic hypoxia. We also analyzed prenatal and perinatal history, socioeconomic living conditions of these children, i.e. their nutrition, and if they had previously received oral iron preparations. Some of the results, such as inadequate alimentation with flour, as well as insufficient prophylaxis of iron deficiency, which were found in most cases of severe anemia, point to the need of paying greater attention to this problem, better parents education, and more adequate screening for iron deficiency anemia.

    Full Text Available The numbers of older people in the world have been growing rapidly. Anemia is the most common hematologic problem encountered in older adults. However, anemia should not be accepted as an inevitable consequence of aging. Anemia in the elderly signifies an underlying disease. Iron Defi ciency Anemia (IDA is being one of the most common causes of anemia in older people. IDA in the elderly is often associated with such non specific symptoms. The diagnosis of IDA is typically based on laboratory results. Hence, the utilization of the various laboratory tests plays an important role for the diagnosis of IDA. The presence of IDA in the elderly is usually related with gastrointestinal disorders. Thus,  gastrointestinal evaluation should be contemplated in all patients with IDA unless there is a history of clinically important non gastrointestinal blood loss. Older people with IDA should have iron supplementation both to correct anemia and to replenish body iron stores. However, the underlying cause should always be treated to prevent further iron loss.

    Full Text Available Background: Anemia during pregnancy is a global public health challenge facing the world today. Prevalence of anemia in pregnancy in all the age groups is higher in India as compared to other developing countries. Objective: This study is aimed at determining the magnitude and to explore the socio-demographic and other correlates of anemia among pregnant women. Methodology: This descriptive study with cross-sectional design was conducted in a tertiary care hospital. Pregnant who were attending antenatal clinic for a period of one year were comprised the study material. Correlation between variables was analyzed using the chi-square and odd ratio. Results: Three hundred and thirty eight pregnant women were registered for the present study, whose age ranged from 16 to 45 years with a mean age of 26.08 years. Majority (81.95% participants were found to be anemic. It was observed that anemia was more prevalent in pregnant women age groups i.e. 25-29 years and 30+years i.e. 86.67% and 86.21% respectively. Anemia was 82.92% in women were belonging to Hindu and others religion and 82.24% in women having vegetarian diet. Maximum prevalence (83.93% of anemia was observed in women who were booked for antenatal care in the 3rd trimester of pregnancy. The prevalence of anemia is higher (>85% in women having parity two or more, but this association was not statistically significant. Very few (6.21% were found to be severely anemic as compared to women who were moderately anemic (43.19%. Multiple logistic regression analysis of these factors showed that possibility of anemia is less in women who belong to rural area and it is highly significant. Analysis further showed significant association between anemia and type of diet and other factors like women having parity 1 and 4. Conclusion: The prevalence of anemia amongst the pregnant participants was very high. The socio-demographic and obstetrics factors were found to be associated with anemia. To prevent

    .4%, leukopenia (8.26%, and macrocytic alterations (18.4%. Conclusion: Anemia was frequently diagnosed in this series of elderly patients. Partly treatable nutritional deficiencies, such as iron or folate deficiency, were identified as possible causes. A complex and heterogeneous interplay of chronic inflammation, functional iron deficiency, and renal impairment was identified in a large proportion of patients. A hitherto undiagnosed myelodysplastic syndrome can be assumed in a relevant proportion of patients. Morphologic classification based on mean corpuscular volume is inadequate from the standpoint of pathogenesis. New parameters are needed to differentiate the multifactorial pathogenesis of anemia in the elderly.Keywords: anemia, elderly, prevalence, causes, myelodysplastic syndromes

    Hemolytic anemia due to immune function is one of the major causes of acquired hemolytic anemia. In recent years, as more is known about the immune system, these entities have become better understood and their treatment improved. In this section, we will discuss three areas in which this progress has been apparent. In Section I, Dr. Peter Hillmen outlines the recent findings in the pathogenesis of paroxysmal nocturnal hemoglobinuria (PNH), relating the biochemical defect (the lack of glycosylphosphatidylinositol [GPI]-linked proteins on the cell surface) to the clinical manifestations, particularly hemolysis (and its effects) and thrombosis. He discusses the pathogenesis of the disorder in the face of marrow dysfunction insofar as it is known. His major emphasis is on innovative therapies that are designed to decrease the effectiveness of complement activation, since the lack of cellular modulation of this system is the primary cause of the pathology of the disease. He recounts his considerable experience with a humanized monoclonal antibody against C5, which has a remarkable effect in controlling the manifestations of the disease. Other means of controlling the action of complement include replacing the missing modulatory proteins on the cell surface; these studies are not as developed as the former agent. In Section II, Dr. Alan Schreiber describes the biochemistry, genetics, and function of the Fc gamma receptors and their role in the pathobiology of autoimmune hemolytic anemia and idiopathic thrombocytopenic purpura due to IgG antibodies. He outlines the complex varieties of these molecules, showing how they vary in genetic origin and in function. These variations can be related to three-dimensional topography, which is known in some detail. Liganding IgG results in the transduction of a signal through the tyrosine-based activation motif and Syk signaling. The role of these receptors in the pathogenesis of hematological diseases due to IgG antibodies is

    Egyed, Miklós

    2014-03-09

    The author presents a novel algorithm for anaemia based on the erythrocyte haemoglobin content. The scheme is based on the aberrations of erythropoiesis and not on the pathophysiology of anaemia. The hemoglobin content of one erytrocyte is between 28-35 picogram. Any disturbance in hemoglobin synthesis can lead to a lower than 28 picogram hemoglobin content of the erythrocyte which will lead to hypochromic anaemia. In contrary, disturbances of nucleic acid metabolism will result in a hemoglobin content greater than 36 picogram, and this will result in hyperchromic anaemia. Normochromic anemia, characterised by hemoglobin content of erythrocytes between 28 and 35 picogram, is the result of alteration in the proliferation of erythropoeisis. Based on these three categories of anaemia, a unique system can be constructed, which can be used as a model for basic laboratory investigations and work-up of anaemic patients.

    Sideroblastic anemias are caused by a diversity of hereditary, congenital, or acquired disorders. Criteria used in describing sideroblastic anemias vary widely among standard medical textbooks and even so have been imprecisely applied in the literature. Recent discoveries concerning the basic pathophysiologic mechanisms involving the molecular biology of nuclear and mitochondrial DNA, erythroid ALA synthase (ALAS-2), and iron transport have made the classification of sideroblastic anemias very complex. We recommend a more precise evaluation and documentation of the components that characterize the sideroblastic abnormality and propose an extended classification of the sideroblastic anemias.

    The classification of autoimmune hemolytic anemias and the complement system are reviewed. In autoimmune hemolytic anemia of the warm antibody type, complement-mediated cell lysis is clinically relevant in a proportion of the patients but is hardly essential for hemolysis in most patients. Cold antibody-mediated autoimmune hemolytic anemias (primary cold agglutinin disease, secondary cold agglutinin syndrome and paroxysmal cold hemoglobinuria) are entirely complement-mediated disorders. In cold agglutinin disease, efficient therapies have been developed in order to target the pathogenic B-cell clone, but complement modulation remains promising in some clinical situations. No established therapy exists for secondary cold agglutinin syndrome and paroxysmal cold hemoglobinuria, and the possibility of therapeutic complement inhibition is interesting. Currently, complement modulation is not clinically documented in any autoimmune hemolytic anemia. The most relevant candidate drugs and possible target levels of action are discussed.

    Iron deficiency is more common in women due to uterine bleeding, which affects them throughout their fertile life. Additionally, iron needs increase physiologically during pregnancy and breastfeeding. Pregnant women therefore constitute one of the risk groups for iron deficiency. During the postpartum period, iron deficiency is the most common cause of anemia. Longer hospital stays and greater susceptibility to infections are potential consequences of postpartum anemia.

    Summary Iron deficiency and immune activation are the two most frequent causes of anemia, both of which are based on disturbances of iron homeostasis. Iron deficiency anemia results from a reduction of the body’s iron content due to blood loss, inadequate dietary iron intake, its malabsorption, or increased iron demand. Immune activation drives a diversion of iron fluxes from the erythropoietic bone marrow, where hemoglobinization takes place, to storage sites, particularly the mononuclear ph...

    Full Text Available Anemia of cancer (AC may contribute to cancer-related fatigue and impair quality of life. Improved understanding of the pathogenesis of AC could facilitate better treatment, but animal models to study AC are lacking. We characterized four syngeneic C57BL/6 mouse cancers that cause AC. Mice with two different rapidly-growing metastatic lung cancers developed the characteristic findings of anemia of inflammation (AI, with dramatically different degrees of anemia. Mice with rapidly-growing metastatic melanoma also developed a severe anemia by 14 days, with hematologic and inflammatory parameters similar to AI. Mice with a slow-growing peritoneal ovarian cancer developed an iron-deficiency anemia, likely secondary to chronically impaired nutrition and bleeding into the peritoneal cavity. Of the four models, hepcidin mRNA levels were increased only in the milder lung cancer model. Unlike in our model of systemic inflammation induced by heat-killed Brucella abortus, ablation of hepcidin in the ovarian cancer and the milder lung cancer mouse models did not affect the severity of anemia. Hepcidin-independent mechanisms play an important role in these murine models of AC.

    Full Text Available Iron-deficiency anemia is a common reason for referral to a gastroenterologist. In adult men and postmenopausal women, gastrointestinal tract pathology is often the cause of iron-deficiency anemia, so patients are frequently referred for endoscopic evaluation. Endoscopy may be costly and at times difficult for the patient. Therefore, physicians need to know what lesions can be identified reliably and, more importantly, the importance of ruling out life-threatening conditions such as occult malignancy. Over the past decade, a number of prospective studies have been completed that examined the yield of endoscopy in the investigation of iron-deficiency anemia. The present article provides a broad overview of iron-deficiency anemia, with particular emphasis on hematological diagnosis, etiology, the use of endoscopy in identifying lesions and iron-repletion therapy. Other clinical scenarios, including assessment of patients on anti-inflammatory or anticoagulation therapy and patients with bleeding of obscure origin, are also addressed. The present article provides a diagnostic algorithm to iron-deficiency anemia, which describes a more systematic manner in which to approach iron-deficiency anemia.

    Abstract Many patients with congestive heart failure (CHF) fail to respond to maximal CHF therapy and progress to end stage CHF with many hospitalizations, very poor quality of life, end stage renal failure, or die of cardiovascular complications within a short time. One factor that has generally been ignored in many of these patients is the fact that they are often anemic.The anemia is due mainly to renal failure but also to the inhibitory effects of cytokines on the bone marrow. Anemia itself may further worsen the cardiac function and make the patients resistant to standard CHF therapies. Indeed anemia has been associated with increased severity of CHF, increased hospitalization, worse cardiac function and functional class, higher doses of diuretics,worsening of renal function and reduced quality of life. In both controlled and uncontrolled studies the correction of the anemia with erythropoietin (EPO) and oral or Ⅳ iron is associated with improvement in all these parameters. EPO itself may also play a direct role in improving the heart unrelated to the improvement of the anemia. Anemia may also play a role in the worsening of coronary heart disease even without CHF.

    Science.gov (United States)

    Sheftel, Alex D; Richardson, Des R; Prchal, Josef; Ponka, Prem

    2009-01-01

    Sideroblastic anemias are a heterogeneous group of disorders, characterized by mitochondrial iron overload in developing red blood cells. The unifying characteristic of all sideroblastic anemias is the ring sideroblast, which is a pathological erythroid precursor containing excessive deposits of non-heme iron in mitochondria with perinuclear distribution creating a ring appearance. Sideroblastic anemias may be hereditary or acquired. Hereditary sideroblastic anemias are caused by defects in genes present on the X chromosome (mutations in the ALAS2, ABCB7, or GRLX5 gene), genes on autosomal chromosomes, or mitochondrial genes. Acquired sideroblastic anemias are either primary (refractory anemia with ring sideroblasts, RARS, representing one subtype of the myelodysplastic syndrome) or secondary due to some drugs, toxins, copper deficiency, or chronic neoplastic disease. The pathogenesis of mitochondrial iron loading in developing erythroblasts is diverse. Ring sideroblasts can develop as a result of a heme synthesis defect in erythroblasts (ALAS2 mutations), a defect in iron-sulfur cluster assembly, iron-sulfur protein precursor release from mitochondria (ABCB7 mutations), or by a defect in intracellular iron metabolism in erythroid cells (e.g. RARS).

    Iron is an important micronutrient that may be depleted in celiac disease. Iron deficiency and anemia may complicate well-established celiac disease, but may also be the presenting clinical feature in the absence of diarrhea or weight loss. If iron deficiency anemia occurs, it should be thoroughly evaluated, even if celiac disease has been defined since other superimposed causes of iron deficiency anemia may be present. Most often, impaired duodenal mucosal uptake of iron is evident since surface absorptive area in the duodenum is reduced, in large part, because celiac disease is an immune-mediated disorder largely focused in the proximal small intestinal mucosa. Some studies have also suggested that blood loss may occur in celiac disease, sometimes from superimposed small intestinal disorders, including ulceration or neoplastic diseases, particularly lymphoma. In addition, other associated gastric or colonic disorders may be responsible for blood loss. Rarely, an immune-mediated hemolytic disorder with increased urine iron loss may occur that may respond to a gluten-free diet. Reduced expression of different regulatory proteins critical in iron uptake has also been defined in the presence and absence of anemia. Finally, other rare causes of microcytic anemia may occur in celiac disease, including a sideroblastic form of anemia reported to have responded to a gluten-free diet.

    Full Text Available Patients with chronic kidney diseases (CKDs and cardiovascular diseases (CVDs present with various degree of anemia. Anemia has been associated with poor outcome in patients with CKD and CVD. CVD is the commonest cause of morbidity and mortality in patients with CKD. CKD causes anemia and CVD, and this rapidly deteriorates when anemia is not corrected. This triad of CVD, CKD, and anemia has been termed cardio-renal-anemia syndrome. The objec-tive of this study is to highlight the importance of cardio-renal-anemia syndrome, their relation-ship, and management. Three patients with various stages of CKD who presented with anemia and cardiovascular abnormalities are reported. The patients responded well to various interventional measures, with improvement in their clinical and laboratory parameters. Cardio-renal-anemia syndrome is an entity that should be identified. Early and appropriate intervention leads to better outcome.

    The most common hematologic complication of inflammatory bowel disease (IBD)--ulcerative colitis and Crohn's Disease is anemia. Anemia in patients with IBD may be a result of iron, vitamin B12 or folate deficiency; anemia of chronic disease and hemolytic anemia are other causes in these patients. Factors contributing to the development of anemia include chronic gastrointestinal blood loss, vitamin B12 malabsorption secondary to terminal ileitis, folate deficiency as a result of sulfasalazine therapy. Approximately 30% of patients with IBD have hemoglobin levels below 12 g/dl. The risk of developing anemia relates to disease activity, given that blood loss and inflammatory anemia are triggered by intestinal inflammation. In the management strategy of IBD patients with anemia it is important to distinguish between the different types of anemia in order to decide an appropriate manner of treatment.

    Iron deficiency and anemia are associated with impaired neurocognitive development and immune function in young children. Total body iron, calculated from serum ferritin and soluble transferrin receptor concentrations, and hemoglobin allow for monitoring of the iron and anemia status of children in the United States. The purpose of this analysis is to describe the prevalence of iron deficiency (ID), anemia, and iron deficiency anemia (IDA) among children 1–5 years using data from the 2007–2010 National Health and Nutrition Examination Survey (NHANES). Prevalence of ID, anemia, and IDA among children 1–5 years was 7.1% (5.5, 8.7), 3.2% (2.0, 4.3), and 1.1% (0.6, 1.7), respectively. The prevalence of both ID and anemia were higher among children 1–2 years (p < 0.05). In addition, 50% of anemic children 1–2 years were iron deficient. This analysis provides an update on the prevalence of ID, anemia, and IDA for a representative sample of US children. Our results suggest little change in these indicators over the past decade. Monitoring of ID and anemia is critical and prevention of ID in early childhood should remain a public health priority. PMID:27249004

    A 16-year-old boy who was diagnosed to have sickle cell anemia was referred to our center. The parental consanguinity, growth retardation and dysmorphic features prompted a search for possible Fanconi's Anemia (FA). The diepoxybutane (DEB) test was positive, confirming FA. The interaction of both diseases might account for his relatively mild phenotype in terms of both sickle cell anemia (or Hb S, HBB: c.20A > T) and FA. The high Hb F level that might be related to concomitant FA, may have caused a milder phenotype of sickle cell anemia, whereas nitric oxide (NO) depletion as a consequence of sickle cell anemia, may have caused a delay in the bone marrow failure of FA.

    Full Text Available Introduction: Anemia is more common and pronounced in patients with diabetic, than in patients with non-diabetic renal disease. While several factors contribute to its pathogenesis, the failure of the kidney to increase erythropoietin in response to falling hemoglobin appears to be the dominant factor. The most frequent complications of anemia in diabetic patients include decreased quality of life and work capacity and increased cardiovascular morbidity and mortality. Material and Methods: This cross-sectional multicenter study included a total of 539 patients with type I (~20% and type II diabetes (~80% classified into five stages according to the glomerular filtration rate. Results Diabetic nephropathy appears in stage I, and progresses in all patients to the stage V (p=0.045. The presence of anemia progressively increased from stage I to stage V (from 60% to 100%, p=0.008. Only 62% of patients with anemia were treated (mainly with iron and only 3.4% received erythropoietin treatment. Hypertension was present in 90% of patients in stage I and in 100% of patients in stage V nephropathy. The presence of heart failure increased from 0% (stage I to 51% (stage IV, p=0.03. Around 62% of patients were referred to a nephrologist, and according to the logistic regression model, renal failure and presence of anemia were significant predictors of patients' referral to nephrologist. Conclusion: In a primary care setting, anemia is a frequent finding, even in the very beginning of diabetic renal disease. Currently available guidelines for management of anemia are not followed; this may explain high percentage of patients with heart failure in pre-dialysis stage. Early referral to a nephrologist and regular follow-up by an endocrinologist and cardiologist are the best way for the prevention of diabetic complications and comorbidity.

    Full Text Available No presente artigo abordaram-se vários aspectos relacionados à natureza molecular da anemia falciforme, desordem hematológica de caráter hereditário que acomete expressivo número de indivíduos em várias regiões do mundo. As pesquisas realizadas em torno desta patologia da hemácia, ao longo de quase um século, a partir de 1910, cooperaram para a criação de um novo e importante segmento da ciência, denominado biologia molecular. A descoberta dos polimorfismos da mutação (GAT->GTG no gene que codifica a cadeia beta da hemoglobina, originando diferentes haplótipos da doença, permitiu um melhor e mais amplo conhecimento em torno da heterogeneidade clínica nos pacientes falcêmicos. Analisando a hemoglobina na sua estrutura normal e mutante, sua produção e evolução, pode-se ter um entendimento mais completo da fisiopatologia desta doença e da sua complexidade clínica.

    Full Text Available Due to the reduction in the number of red blood cells, caused by the immune system, the immune-mediated hemolytic anemia (IMHA is the most common disease among the hemolytic anemias and occurs more frequently in dogs (Nelson & Couto, 2010, wherein the most affected breeds are Cocker Spaniel, Poodle, Doberman and Collie (ETTINGER; FELDMAN 2004; THRALL et al 2007.. There is no pathognomonic sign for the diagnosis of the immune-mediated hemolytic anemia; however, laboratory findings show regenerative anemia, spherocytosis, positive results in Coombs' test and rarely, monocytes with hemosiderin or erythrocytes phagocytosis, but even with these findings, the primary and secondary IMHA can not be differentiate from each other. Differentiation can only be achieved when there is a deep investigation into the cause of the anemia. The IMHA therapeutics starts with the support treatment and follows with an immunosuppressive therapy. In relation to IMHA Mortality rates, the numbers range from 25% to 50% (Thrall, 2007, or above 70% (CARR; Panciera; Kidd, 2002.

  1. Hereditary sideroblastic anemias: pathophysiology, diagnosis, and treatment.

    2009-10-01

    Inherited sideroblastic anemia comprises several rare anemias due to heterogeneous genetic lesions, all characterized by the presence of ringed sideroblasts in the bone marrow. This morphological aspect reflects abnormal mitochondrial iron utilization by the erythroid precursors. The most common X-linked sideroblastic anemia (XLSA), due to mutations of the first enzyme of the heme synthetic pathway, delta-aminolevulinic acid synthase 2 (ALAS2), has linked heme deficiency to mitochondrial iron accumulation. The identification of other genes, such as adenosine triphosphate (ATP) binding cassette B7 (ABCB7) and glutaredoxin 5 (GLRX5), has strengthened the role of iron sulfur cluster biogenesis in sideroblast formation and revealed a complex interplay between pathways of mitochondrial iron utilization and cytosolic iron sensing by the iron-regulatory proteins (IRPs). As recently occurred with the discovery of the SLC25A38-related sideroblastic anemia, the identification of the genes responsible for as yet uncharacterized forms will provide further insights into mitochondrial iron metabolism of erythroid cells and the pathophysiology of sideroblastic anemia.

    Full Text Available Objective: The aim of this study was to analyze the reticulocyte maturity indices (low, medium, and high fluorescence ratios in iron deficient 1- to 6-year-old children, and identify the prevalence of iron deficiency anemia in this population. Methods: The present study included 39 subjects, divided into two groups: control subjects (n = 33, and subjects with iron deficiency anemia (n = 6. The results were analyzed by Student's t-test for comparison of means. Differences were considered significant when two-tailed p-value < 0.05. Results: Subjects with iron deficiency anemia presented increases in the proportion of mean (10.3 ± 4.7% vs. 6.0 ± 3.4%; p-value = 0.003, and high fluorescence reticulocytes (2.3 ± 0.87% vs. 0.9 ± 0.9%; p-value = 0.03 compared to the control group. The prevalence of anemia in this population was 15% (n = 6. Conclusion: The indices related to immaturity of reticulocytes are higher in the presence of iron deficiency, thus demonstrating a deficiency in the raw material to form hemoglobin and are, therefore, possible early markers of iron deficiency and anemia. We emphasize the need to standardize these indices for use in clinical practice and lab test results.

    Anemia is one of the most common public health problems in developing countries like Nepal. This study was done to find the prevalence of anemia among the children aged 4-13 years in eastern Nepal. A cross-sectional study was conducted in 2012 in four districts (Morang, Udayapur, Bhojpur and Ilam) of eastern Nepal to find the prevalence of anemia among the school children of eastern Nepal. Children aged 4-13 years were selected randomly from different schools of above districts and 618 venous blood samples were collected. Hemoglobin level was estimated by using cyanmethemoglobin method. The mean hemoglobin level was 12.2 ± 1.82 gm/dl. About 37.9% (n = 234) children were found anemic. Anemia prevalence was 42.4% (n = 78), 31.6% (n = 60), 45.3% (n = 48) and 34.8% (n = 48) among school children of Morang, Udayapur, Bhojpur and Ilam district, respectively. The study finds anemia as a significant health problem among the school children of eastern Nepal.

    Iron is essential for life because it is indispensable for several biological reactions, such as oxygen transport, DNA synthesis, and cell proliferation. Over the past few years, our understanding of iron metabolism and its regulation has changed dramatically. New disorders of iron metabolism have emerged, and the role of iron as a cofactor in other disorders has begun to be recognized. The study of genetic conditions such as hemochromatosis and iron-refractory iron deficiency anemia (IRIDA) has provided crucial insights into the molecular mechanisms controlling iron homeostasis. In the future, these advances may be exploited to improve treatment of both genetic and acquired iron disorders. IRIDA is caused by mutations in TMPRSS6, the gene encoding matriptase-2, which downregulates hepcidin expression under conditions of iron deficiency. The typical features of this disorder are hypochromic, microcytic anemia with a very low mean corpuscular volume of erythrocytes, low transferrin saturation, no (or inadequate) response to oral iron, and only a partial response to parenteral iron. In contrast to classic iron deficiency anemia, serum ferritin levels are usually low-normal, and serum or urinary hepcidin levels are inappropriately high for the degree of anemia. Although the number of cases reported thus far in the literature does not exceed 100, this disorder is considered the most common of the "atypical" microcytic anemias. The aim of this review is to share the current knowledge on IRIDA and increase awareness in this field.

    Full Text Available Background: The aim of the present study was to find out the variation of pulmonary function parameters in different trimesters of pregnancy as well as variation according to severity of anemia in each trimester. Methods: The present case control study was carried out in the post-graduate department of obstetrics and gynecology, M.K.C.G. medical college and hospital, Berhampur, during the period from October 2012 to October 2013. This study entitled and ldquo;Pulmonary functions in pregnancy complicated with anemia and rdquo;, embodies the pulmonary functions of 60 anemic pregnant females (study group and 100 healthy pregnant females (control in different trimesters of pregnancy. The pulmonary function parameters, which were studied, are FVC, FEV1, FEV1/FVC, FEF25-75%, PEFR and MVV in both the study and control group. Results: Comparing the variation with advancing gestation in study and control, it was seen that FVC, FEV1, FEV1/FVC and FEF25-75% showed no significant alteration. With increasing severity of anemia compared to controls, FVC, FEV1, PEFR and MVV values reduce significantly. As FEF25-75% is not effort dependent, it shows no significant variation. Conclusion: Thus from this study, it can be concluded that moderate to severe anemia in pregnancy can adversely affect pulmonary functions. Hence nutritional anemia in early pregnancy should be provided with iron supplements in order to prevent adverse obstetric outcomes. [Int J Res Med Sci 2014; 2(4.000: 1431-1437

    Objectives: Anemia is associated with increased mortality in patients with acute symptomatic pulmonary embolism (PE). The purpose of this study was to evaluate the feasibility of Hounsfield unit (HU) measurements on the single unenhanced trigger slice of pulmonary CT angiography scans for diagnosis of anemia. Material and Methods: 150 consecutive patients (median age 64 ± 16 years) with suspected PE underwent pulmonary CT angiography. Two radiologists, blinded to laboratory results, performed HU measurements in the single unenhanced trigger scan independently by region-based analysis (ROI). HU values from ascending and descending aorta and the calculated mean of both were correlated with serum hemoglobin levels. Inter- and intraobserver variability was determined for HU measurements, and ROC analysis was performed for diagnosis of anemia. Calculated linear models were used to assess formulas for estimation of hemoglobin levels from HU measurements. Results: HU measurements revealed high intra- and interrater reliability (ICC > 0.981 and ICC > 0.965, respectively). Calculated mean HU values showed a strong correlation with serum hemoglobin levels (r = 0.734), which allowed generation of different formulas for calculation of hemoglobin levels from HU measurements. ROC analyses confirmed a high sensitivity (80.4 for men; 91.3 for women) and specificity (84.0 for men; 84.9 for women) for diagnosing anemia. Conclusion: Diagnosis of anemia and quantification of hemoglobin levels upon a single unenhanced trigger scan of pulmonary CT angiography is feasible. We suggest disclosing the anemic state in the radiological report, independent of the presence of PE, since anemia carries increased risks of morbidity and mortality.

    Hereditary sideroblastic anemia (HSA) is a heterogeneous group of inherited anemic disorders which is characterized by the presence of ringed sideroblasts in the bone marrow, microcytic hypochromic anemia and typically its X-linked inheritance in patients. It has been shown that a deficiency of the erythroid-specific delta-aminolevulinate synthase (ALAS-E) activity is responsible for pyridoxine-responsive HSA in many patients, however, the pathogenesis of other types of HSA remains still unknown. In this article, recent evidence suggesting multiple causes for HSA is summarized and discussed.

    The aim of the study was to evaluate the clinical efficiency of soluble transferrin receptor and transferrin receptor-ferritin index (sTfR/logF) in the diagnosis of iron deficiency anemia, as well as the differential diagnosis of iron deficiency anemia and anemia in rheumatoid arthritis. The study included 96 patients with anemia and 61 healthy volunteers as a control group. In healthy subjects there were no significant sex and age differences in the parameters tested. The study results showed these parameters to be reliable in the diagnosis of iron deficiency anemia, as well as in the differential diagnosis of iron deficiency anemia and anemia of chronic disease. The results indicate that sTfR/logF could be used to help differentiate coexisting iron deficiency in patients with anemia of chronic disease. Receiver operating characteristic analysis showed a higher discriminating power of transferrin receptor-ferritin index vs. soluble transferrin receptor in the diagnosis of iron deficiency anemia, as well as in the differential diagnosis between iron deficiency anemia and anemia of chronic disease. In patients with anemia in rheumatoid arthritis, the parameters tested showed no significant differences with respect to C-reactive protein concentration. These results suggested that the parameters tested are not affected by acute or chronic inflammatory disease.

    A 59-year-old man was orally administered rabeprazole, a proton pump inhibitor (PPI), for gastroesophageal reflux disease, after which he gradually developed iron-deficiency anemia. The anemia did not improve following the administration of ferrous fumarate, and endoscopic screening of the entire gastrointestinal tract, including the small intestine, did not reveal any findings indicating the cause of the anemia. The patient was then switched from rabeprazole to famotidine and the anemia was cured within three months. There is much debate as to whether the long-term use of PPIs causes iron-deficiency. However, this case strongly suggests that PPIs can induce iron-deficiency anemia.

    Hemolytic anemia has been reported to occur in the setting of aortic stenosis and prosthetic heart valves, but much more rarely in association with obstructive hypertrophic cardiomyopathy (HC). Of the few descriptions of hemolytic anemia secondary to HC, all but one case involved bacterial endocarditis contributing to left ventricular outflow tract obstruction. We present the case of a 67-year-old man with recurrent hemolytic anemia and HC, without infective endocarditis. Attempts at iron repletion and augmentation of beta-blocker therapy proved his anemia to be refractory to medical management. Ventricular septal myectomy led to the resolution of hemolysis, anemia, and its coexisting symptoms. PMID:26424952

    Anemia is a prevalent disease with multiple possible etiologies and resultant complications. Iron deficiency anemia is a common cause of anemia and is typically due to insufficient intake, poor absorption, or overt or occult blood loss. Distinguishing iron deficiency from other causes of anemia is integral to initiating the appropriate treatment. In addition, identifying the underlying cause of iron deficiency is also necessary to help guide management of these patients. We review the key components to an evidence-based, cost-conscious evaluation of suspected iron deficiency anemia.

    Anemia is a common extraintestinal manifestation of inflammatory bowel disease(IBD) and is frequently overlooked as a complication. Patients with IBD are commonly found to have iron deficiency anemia(IDA) secondary to chronic blood loss, and impaired iron absorption due to tissue inflammation. Patients with iron deficiency may not always manifest with signs and symptoms; so, hemoglobin levels in patients with IBD must be regularly monitored for earlier detection of anemia. IDA in IBD is associated with poor quality of life, necessitating prompt diagnosis and appropriate treatment. IDA is often associated with inflammation in patients with IBD. Thus, commonly used labora-tory parameters are inadequate to diagnose IDA, and newer iron indices, such as reticulocyte hemoglobin content or percentage of hypochromic red cells or zinc protoporphyrin, are required to differentiate IDA from anemia of chronic disease. Oral iron preparations are available and are used in patients with mild disease activity. These preparations are inexpensive and con-venient, but can produce gastrointestinal side effects, such as abdominal pain and diarrhea, that limit their use and patient compliance. These preparations are partly absorbed due to inflammation. Non-absorbed iron can be toxic and worsen IBD disease activity. Although cost-effective intravenous iron formulations are widely available and have improved safety profiles, physicians are reluctant to use them. We present a review of the pathophysiologic mechanisms of IDA in IBD, improved diagnostic and therapeutic strategies, efficacy, and safety of iron replacement in IBD.

    Hereditary sideroblastic anemia is a very rare disease recessive and X-linked that affect heme biosynthesis by deficit or decreased of delta aminolevulinic acid synthase (ALAS) activity. We report a case of a six-month-old boy, admitted in the hospital for anemic syndrome. The hemogram showed anemia (hemoglobin: 4.5 g/dL), frankly hypochronic microcytic and a regenerated (mean corpuscular hemoglobin concentration: 26 g/dL, mean cell volume: 53 fl, reticulocytes: 10 x 10(9)/L) with red cells morphologic disorders in smears (anisopoikylocytosis) without attack of the other lineages; white blood cells: 11 x 10(9)/L (neutrophils: 64% and lymphocytes: 35%); platelets: 350 x 10(9)/L. Examination of bone marrow showed an important erythroid hyperplasia (about 69%) with dyserythropoiesis. Perls stain revealed intense siderosis with 90% of ringed sideroblasts and a large number of siderocytes. Exploration of ALAS2 and ABC7 genes on the DNA of the infant was not found abnormalities. Treatment with pyridoxine corrects moderately the anemia. By the way, we proposed to remind that iron deficiency, inflammatory syndrome and thalassemia are the common microcytic anemia. However, it's mandatory to explore other causes if diagnosis is not solved.

    Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD) and is frequently overlooked as a complication. Patients with IBD are commonly found to have iron deficiency anemia (IDA) secondary to chronic blood loss, and impaired iron absorption due to tissue inflammation. Patients with iron deficiency may not always manifest with signs and symptoms; so, hemoglobin levels in patients with IBD must be regularly monitored for earlier detection of anemia. IDA in IBD is associated with poor quality of life, necessitating prompt diagnosis and appropriate treatment. IDA is often associated with inflammation in patients with IBD. Thus, commonly used laboratory parameters are inadequate to diagnose IDA, and newer iron indices, such as reticulocyte hemoglobin content or percentage of hypochromic red cells or zinc protoporphyrin, are required to differentiate IDA from anemia of chronic disease. Oral iron preparations are available and are used in patients with mild disease activity. These preparations are inexpensive and convenient, but can produce gastrointestinal side effects, such as abdominal pain and diarrhea, that limit their use and patient compliance. These preparations are partly absorbed due to inflammation. Non-absorbed iron can be toxic and worsen IBD disease activity. Although cost-effective intravenous iron formulations are widely available and have improved safety profiles, physicians are reluctant to use them. We present a review of the pathophysiologic mechanisms of IDA in IBD, improved diagnostic and therapeutic strategies, efficacy, and safety of iron replacement in IBD. PMID:26301120

    Hysterectomy is the second-most-common surgical procedure among premenopausal women. The conditions that lead to the need for a hysterectomy often are accompanied by chronic blood loss that can lead to anemia. Moreover, hysterectomy and myomectomy may result in significant blood loss, which exacerbates the anemia. The presence of fatigue associated with anemia has a substantially negative impact on quality of life and the ability to perform activities of daily living. Options for alleviating perioperative anemia include minimizing surgical blood loss, blood transfusion, supplementation with hematinics, such as iron and folic acid, and treatment with recombinant human erythropoietin. Treating preoperative anemia is expected to help correct anemia prior to surgery and may have a positive impact on anemia-related symptoms and surgical outcomes.

    Full Text Available OBJECTIVE: Post-transplant anemia is a common complication in renal allograft recipients. The most common causes are impaired graft function, immunosuppressive drugs, and infections. The aim of our study was to further investigate the prevalence of anemia before and after renal transplantation in renal allograft recipients in Turkey. MATERIAL and METHODS: We assessed 464 patients who received a kidney transplant between the years 2010 and 2012. The prevalence of anemia was evaluated before transplantation and at the 3 rd and at 6th months after transplantation. Our study is a retrospective study. RESULTS: The prevalence of anemia at the 6th month after the transplant surgery was 28.8%. The percentage of the patients who did not have anemia prior to the transplant surgery, and who developed anemia after the transplantation was 24.4%. CONCLUSION: Our findings are similar to those found in the literature, and show that anemia is a very common entity after renal transplantation.

    A 62 year old male (R.H.) presented with a mild anemia (Hb 11-12 gm%) and a history of multiple hemorrhagic episodes. The marrow had 40-50% sideroblasts. Marrow chromosomes were normal. His wife was hematologically normal, while one daughter, age 30 years, had a sideroblastic anemia (Hb 11-12 gm%) with 40-50% sideroblasts in the marrow. Her anemia was first noted at age 15 years. Administration of vitamin B6 did not correct the anemia in either the father or daughter. Platelet abnormalities inherited jointly with this disorder are described for the first time. Both R.H. and his daughter had prolonged bleeding times, with normal PTT, PT times, fVIII:C, fVIII:Ag levels, and vWF multimers, which may rule out a von Willebrand's disease. They have normal platelet numbers but abnormally low platelet adhesiveness and greatly depressed ADP, collagen, and epinephrine responsiveness. Response to ristocetin was in the low normal range, and aggregation with thrombin was normal. While desmopressin completely normalized R.H.'s bleeding time, none of these platelet parameters were improved. No differences in the SDS PAGE protein patterns of RH platelets could be detected in comparison to normal samples. His platelets took up and released serotonin (5HT) normally, and electron micrographs defined no morphological abnormalities. However, no ATP was released from platelets activated with collagen, and when followed by thrombin about fourfold greater ATP was released by control platelets as compared to RH platelets. The dense granule fraction derived from RH platelets contained about 20% the level of ATP, 40% the level of ADP, and 50% the level of 5HT detected in a normal sample. The results indicate that the bleeding disorder is related to a non-classical heritable storage pool defect. The connection between the inherited sideroblastic anemia and platelet defects is obscure.

    Full Text Available In many elderly patients with anemia, a specific cause cannot be identified. This study investigates whether erythropoietin levels are inappropriately low in these cases of "anemia of unknown etiology" and whether this trend persists after accounting for confounders.This study includes all anemic patients over 60 years old who had erythropoietin measured between 2005 and 2013 at a single center. Three independent reviewers used defined criteria to assign each patient's anemia to one of ten etiologies: chronic kidney disease, iron deficiency, chronic disease, confirmed myelodysplastic syndrome (MDS, suspected MDS, vitamin B12 deficiency, folate deficiency, anemia of unknown etiology, other etiology, or multifactorial etiology. Iron deficiency anemia served as the comparison group in all analyses. We used linear regression to model the relationship between erythropoietin and the presence of each etiology, sequentially adding terms to the model to account for the hemoglobin concentration, estimated glomerular filtration rate (eGFR and Charlson Comorbidity Index.A total of 570 patients met the inclusion criteria. Linear regression analysis showed that erythropoietin levels in chronic kidney disease, anemia of chronic disease and anemia of unknown etiology were lower by 48%, 46% and 27%, respectively, compared to iron deficiency anemia even after adjusting for hemoglobin, eGFR and comorbidities.We have shown that erythropoietin levels are inappropriately low in anemia of unknown etiology, even after adjusting for confounders. This suggests that decreased erythropoietin production may play a key role in the pathogenesis of anemia of unknown etiology.

    Cancer related anemia (CRA) adversely affects patient Quality of Life (QoL) and overall survival. We prospectively studied the prevalence, etiology and the impact of anemia on QoL in 218 Indian cancer patients attending a tertiary referral hospital. The study used the sTfR/log Ferritin index to detect iron deficiency anemia and assessed patient QoL using the Functional Assessment of Cancer Therapy-Anemia (FACT-An) tool, standardized for language. Mean patient age was 51±13 years and 60% were female. The prevalence of cancer related anemia in this setting was 64% (n = 139). As expected, plasma ferritin did not differ significantly between anemic (n = 121) and non-anemic cancer patients (n = 73). In contrast, plasma sTfR levels were significantly higher in anemic cancer patients compared to non-anemic cancer patients (31 nmol/L vs. 24 nmol/L, p = 0.002). Among anemic cancer patients, using the sTfR/log Ferritin index, we found that 60% (n = 83) had iron deficiency anemia (IDA). Interestingly, plasma sTfR levels were significantly higher in cancer patients with CRA+IDA (n = 83) compared with patients having CRA (n = 38) alone (39 nmol/L vs. 20 nmol/L, p<0.001). There was a significant linear correlation between Hb and QoL (Spearman ρ = 0.21; p = 0.001) and multivariate regression analysis revealed that every gram rise in Hb was accompanied by a 3.1 unit increase in the QoL score (95% CI = 0.19–5.33; p = 0.003). The high prevalence of anemia in cancer patients, a major portion of which is due to iron deficiency anemia, the availability of sensitive and specific biomarkers of iron status to detect IDA superimposed on anemia of inflammation, suggests an urgent need to diagnose and treat such patients. Despite the potential negative consequences of increasing metabolically available plasma iron in cancer, our clinical data suggest that detecting and treating IDA in anemic cancer patients will have important consequences to their QoL and overall survival.

    Full Text Available INTRODUCTION: Anemia is defined as haemoglobin level in the blood below the lower extreme of the normal range for the age and sex of the individual. According to WHO, in developing countries the prevalence of anemia among pregnant women averages 60%, ranging between 35 to 100% among different regions of the world. A hemoglobin concentration below 11.0g/dl or packed cell volume (PCV of less than 33.0% is regarded as anemia during pregnancy by the WHO. It occurs in 40 - 80% of the pregnant women. Iron and folic acid defici encies, malaria, intestinal parasitic infections and hemoglobinopathies are the principal causes of anemia in pregnancy. Predisposing factors include young age, grand multiparity, low socioeconomic status, illiteracy, ignorance and short intervals of pregn ancy. AIM AND OBJECTIVES: 1. To study various patterns of anemia in pregnant women having haemoglobin level < 11 gm%. 2. To determine the most common pattern of anemia in pregnancy based on red cell morphology. MATERIALS AND METHODS: This study is a prospe ctive study over a period of one year from September 2014 to August 2015 in the department of pathology, Andhra medical college, Visakhapatnam . The study was conducted on 120 pregnant women whose haemoglobin level is < 11 gm/dl. All the haemotological parameters & peripheral blood smear stained by Leishman’s stain were evaluated. Complete clinical & obstetric history was recorded. Socioeconomic status was also noted. RESULTS: Out of 120 cases of anemia, we found 47 patie nts (39.1% having dimorphic anemia, 36(30% – microcytic hypochromic anemia, 23(19.1% - normocytic hypochromic anemia, 11(9.16% - sickle cell anemia and 1(0.83% case of pancytopenia.

    Full Text Available James W Swann,1 Barbara J Skelly2 1Queen Mother Hospital for Animals, The Royal Veterinary College, Hatfield, Hertfordshire, 2Department of Veterinary Medicine, University of Cambridge, Cambridge, UK Abstract: Immune-mediated hemolytic anemia is one of the most common manifestations of canine immune-mediated disease, yet treatment regimens remain nonstandardized and, in some cases, controversial. The main reason for this, as for most diseases in veterinary medicine, is the lack of large-scale placebo-controlled trials so that the efficacy of one treatment over another can be established. Most of the evidence used for treatment comes from retrospective studies and from personal preference and experience, and because of this, treatment regimens tend to vary among institutions and individual clinicians. Management of immune-mediated hemolytic anemia includes immunosuppression, thromboprophylaxis, and supportive care measures to help prevent and treat concurrent conditions.

  5. Iron deficiency decreases hemolysis in sickle cell anemia Anemia ferropriva diminui hemólise em anemia falciforme

    Full Text Available A woman with homozygous sickle cell disease developed severe iron deficiency due to long-standing uterine bleeding. At this point, the serum lactic dehydrogenase level was normal and the reticulocyte count was only minimally elevated. This suggested that the low red cell hemoglobin concentration that resulted from iron deficiency also decreased Hb S polymerization and lowered the hemolytic rate. Iron replacement led first to a substantially improved hemoglobin concentration with only a minimal increase in the hemolytic rate and secondarily to a modest further improvement in the hemoglobin concentration and a marked increase in the hemolytic rate. The hematologic changes observed in this patient, and those in other iron deficient sickle cell patients reported in the literature, suggest that it may be appropriate to consider the induction of an intermediate iron deficient stage as experimental treatment in adult sickle cell patients.Uma mulher com anemia falciforme homozigose para a Hb S evoluiu com anemia ferropriva grave devido a sangramento uterino prolongado. A dosagem de dehidrogenase lática era normal e a contagem de reticulócitos estava levemente aumentada. Isto sugere que concentrações baixas de hemoglobina, que resulta de anemia ferropriva, também diminuem a polimeração de Hb S e reduz a taxa de hemólise. O complemento de ferro levou, primeiramente, a uma concentração substancialmente maior de hemoglobina com apenas um aumento mínimo na taxa hemolítica e subsequentemente a um aumento leve adicional na concentração da hemoglobina e um aumento notável na taxa hemolítica. As mudanças hematológicas observadas nesta paciente e aquelas em outras pacientes com anemia falciforme e também deficientes de ferro relatadas na literatura sugerem que pode ser interessante considerar a indução de deficiência de ferro como tratamento experimental em pacientes adultos com anemia falciforme.

    Background In Korea, the prevalence of anemia and iron deficiency anemia (IDA) among older infants and young children remains high. To detect IDA early and to reduce its adverse impact, we assessed the characteristics of infants and young children who had IDA or were at risk of developing IDA, or who exhibited characteristics associated with severe anemia. Methods Among the 1,782 IDA-affected children aged 6 months to 18 years who visited the hospital, we retrospectively analyzed the medical records and laboratory data of 1,330 IDA-affected children aged 6–23 months who were diagnosed between 1996 and 2013. We excluded patients with a C-reactive protein level ≥5 mg/dL. Results IDA was predominant in boys (2.14:1) during infancy and early childhood. The peak IDA incidence was noted among infants aged 9–12 months. Only 7% patients exhibited symptoms of IDA, while 23.6% patients with severe IDA demonstrated classic symptoms/signs of IDA. Low birth weight (LBW) infants with IDA demonstrated low adherence to iron supplementation. In a multivariate analysis, prolonged breastfeeding without iron fortification (odds ratio [OR] 5.70), and a LBW (OR 6.49) were identified as risk factors of severe anemia. Conclusion LBW infants need more attention in order to increase their adherence to iron supplementation. For the early detection of IDA, nutritional status of all infants, and iron batteries of high-risk infants (LBW infants, infants with prolonged breastfeeding, picky eaters, and/or infants with the presence of IDA symptoms) should be evaluated at their health screening visits.

    Anemia represents a substantial problem for children living in areas with limited resources and significant parasite burden. We performed a cross-sectional study of 254 Kenyan preschool- and early school-age children in a setting endemic for multiple chronic parasitic infections to explore mechanisms of their anemia. Complete venous blood cell counts revealed a high prevalence of local childhood anemia (79%). Evaluating the potential links between low hemoglobin and socioeconomic factors, nutritional status, hemoglobinopathy, and/or parasite infection, we identified age anemia. A total of 130/155 (84%) of anemic children with iron studies had evidence of iron-deficiency anemia (IDA), 16% had non-IDA; 50/52 of additionally tested anemic children met soluble transferrin-receptor (sTfR) criteria for combined anemia of inflammation (AI) with IDA. Children in the youngest age group had the greatest odds of iron deficiency (OR: 10.0, 95% CI: 3.9, 26). Although older children aged 9-11 years had less anemia, they had more detectable malaria, Schistosoma infection, hookworm, and proportionately more non-IDA. Anemia in this setting appears multifactorial such that chronic inflammation and iron deficiency need to be addressed together as part of integrated management of childhood anemia.

    Anemia, the most common hematologic abnormality, is a reduction in the concentration of erythrocytes or hemoglobin in blood. The two most common causes of anemia in pregnancy and the puerperium are iron deficiency and acute blood loss. Iron requirements increase during pregnancy, and a failure to maintain sufficient levels of iron may result in adverse maternal-fetal consequences. The purpose of this document is to provide a brief overview of the causes of anemia in pregnancy, review iron requirements, and provide recommendations for screening and clinical management of anemia during pregnancy.

    Occupational lead exposure can cause anemia at blood lead levels >50 microg/dl, as high as rarely occurs in industrialized countries nowadays. Whereas other forms of anemia are fairly probable to be found in lead exposed workers, especially in areas highly endemicfor extraoccupational anemias, such as beta thalassemia and iron deficiency anemia. The etiology of anemias has to be correctly defined in order to assess suitable therapeutical approaches and medicolegal consequences. The objective of this study is to verify in male lead exposed workers whether an accurate evaluation of hemocromocytometric parameters and of usual biological indices of lead exposure and effect on heme can differentiate the most common forms of anemia in Southern Italy. 68 workers occupationally exposed to low to moderate lead doses were studied and 59 workers of an alimentary plant have been taken as control group. On venous blood samples collected from these workers a complete hemocromocytometric test was performed and blood lead and erythrocytic zincoprotoporphyrin were determined. Anemia (Hb lead exposed workers and in a nonexposed worker. The reasoned evaluation of laboratory parameters led to identify among lead exposed workers four subjects with high probability of beta-thalassemic trait and two with lead poisoning anemia. Moreover a diagnostic algorithm was developed based on literature that seems to be able to discriminate lead poisoning from other causes of anemia in lead exposed workers in this study.

    Lead pollution is a substantial problem in developing countries such as India. The US Centers for Disease Control and Prevention has defined an elevated blood lead level in children as > or = 10 microg/dl, on the basis of neurologic toxicity. The US Environmental Protection Agency suggests a threshold lead level of 20-40 microg/dl for risk of childhood anemia, but there is little information relating lead levels anemia. Therefore, the authors examined the association between lead levels as low as 10 mug/dl and anemia in Indian children under 3 years of age. Anemia was divided into categories of mild (hemoglobin level 10-10.9 g/dl), moderate (hemoglobin level 8-9.9 g/dl), and severe (hemoglobin level Lead levels lead levels > or = 10-19.9 microg/dl and 97 (9%) had levels > or = 20 microg/dl. After adjustment for child's age, duration of breastfeeding, standard of living, parent's education, father's occupation, maternal anemia, and number of children in the immediate family, children with lead levels > or = 10 microg/dl were 1.3 (95% confidence interval: 1.0, 1.7) times as likely to have moderate anemia as children with lead levels anemia was 1.7 (95% confidence interval: 1.1, 2.6). Health agencies in India should note the association of elevated blood lead levels with anemia and make further efforts to curb lead pollution and childhood anemia.

    Despite its high prevalence, anemia often does not receive proper clinical attention, and detection, evaluation, and management of iron deficiency anemia and iron-restricted erythropoiesis can possibly be an unmet medical need. A multidisciplinary panel of clinicians with expertise in anemia management convened and reviewed recent published data on prevalence, etiology, and health implications of anemia as well as current therapeutic options and available guidelines on management of anemia across various patient populations and made recommendations on the detection, diagnostic approach, and management of anemia. The available evidence confirms that the prevalence of anemia is high across all populations, especially in hospitalized patients. Anemia is associated with worse clinical outcomes including longer length of hospital stay, diminished quality of life, and increased risk of morbidity and mortality, and it is a modifiable risk factor of allogeneic blood transfusion with its own inherent risks. Iron deficiency is usually present in anemic patients. An algorithm for detection and management of anemia was discussed, which incorporated iron study (with primary emphasis on transferrin saturation), serum creatinine and glomerular filtration rate, and vitamin B12 and folic acid measurements. Management strategies included iron therapy (oral or intravenous), erythropoiesis-stimulating agents, and referral as needed.

    In a patient with sickle cell disease receiving chronic transfusion, exacerbation of anemia with reticulocytopenia must prompt consideration of a delayed hemolytic transfusion reaction with hyperhemolysis, as further transfusion may worsen this condition; definitive diagnosis is sometimes difficult. Anemia evolving during parvovirus B19-induced erythroid hypoplasia (transient aplastic crisis) should be attenuated in chronic transfusion patients due to superior survival of transfused over endogenous red blood cells. A 16-year-old with sickle cell disease receiving chronic transfusion of modified intensity (goal to maintain hemoglobin Sanemia with reticulocytopenia was later shown to have had transient aplastic crisis.

    2012-01-01

    Full Text Available Anemia of any degree is recognized as a significant independent contributor to morbidity, mortality, and frailty in elderly patients. Among the broad types of anemia in the elderly a peculiar role seems to be played by the anemia associated with chronic inflammation, which remains the most complex form of anemia to treat. The origin of this nonspecific inflammation in the elderly has not yet been clarified. It seems more plausible that the oxidative stress that accompanies ageing is the real cause of chronic inflammation of the elderly and that the same oxidative stress is actually a major cause of this anemia. The erythropoietic agents have the potential to play a therapeutic role in this patient population. Despite some promising results, rHuEPO does not have a specific indication for the treatment of anemia in the elderly. Moreover, concerns about their side effects have spurred the search for alternatives. Considering the etiopathogenetic mechanisms of anemia of inflammation in the elderly population, an integrated nutritional/dietetic approach with nutraceuticals that can manipulate oxidative stress and related inflammation may prevent the onset of this anemia and its negative impact on patients’ performance and quality of life.

    Full Text Available Introduction. Iron deficiency anemia and thalassemia are the most common causes of microcytic anemia. Powerful statistical computer programming enables sensitive discriminant analyses to aid in the diagnosis. We aimed at investigating the performance of the multiple discriminant analysis (MDA to the differential diagnosis of microcytic anemia. Methods. The training group was composed of 200 β-thalassemia carriers, 65 α-thalassemia carriers, 170 iron deficiency anemia (IDA, and 45 mixed cases of thalassemia and acute phase response or iron deficiency. A set of potential predictor parameters that could detect differences among groups were selected: Red Blood Cells (RBC, hemoglobin (Hb, mean cell volume (MCV, mean cell hemoglobin (MCH, and RBC distribution width (RDW. The functions obtained with MDA analysis were applied to a set of 628 consecutive patients with microcytic anemia. Results. For classifying patients into two groups (genetic anemia and acquired anemia, only one function was needed; 87.9% β-thalassemia carriers, and 83.3% α-thalassemia carriers, and 72.1% in the mixed group were correctly classified. Conclusion. Linear discriminant functions based on hemogram data can aid in differentiating between IDA and thalassemia, so samples can be efficiently selected for further analysis to confirm the presence of genetic anemia.

    Full Text Available Background. Anemia is a common condition in the elderly and a significant risk factor for increased morbidity and mortality, reducing not only functional capacity and mobility but also quality of life. Currently, few data are available regarding anemia in hospitalized geriatric patients. Our retrospective study investigated epidemiology and causes of anemia in 405 hospitalized geriatric patients. Methods. Data analysis was performed using laboratory parameters determined during routine hospital admission procedures (hemoglobin, ferritin, transferrin saturation, C-reactive protein, vitamin B12, folic acid, and creatinine in addition to medical history and demographics. Results. Anemia affected approximately two-thirds of subjects. Of 386 patients with recorded hemoglobin values, 66.3% were anemic according to WHO criteria, mostly (85.1% in a mild form. Anemia was primarily due to iron deficiency (65%, frequently due to underlying chronic infection (62.1%, or of mixed etiology involving a combination of chronic disease and iron deficiency, with absolute iron deficiency playing a comparatively minor role. Conclusion. Greater awareness of anemia in the elderly is warranted due to its high prevalence and negative effect on outcomes, hospitalization duration, and mortality. Geriatric patients should be routinely screened for anemia and etiological causes of anemia individually assessed to allow timely initiation of appropriate therapy.

    As a common problem in long-term care facilities (LTCFs), anemia affects 25–63% of the elderly. The aim of the present study was to describe the prevalence and characteristics of anemia and its associated factors in the institutionalized elderly. The cross-sectional study was carried out with three hundred thirteen individuals aged ≥ 60 years, of both genders, living in long-term care facilities for the elderly in Salvador, Bahia, Brazil. Poisson regression (PR) with robust variance estimates was used to assess the factors related to anemia. The prevalence of anemia was 38%. Mild anemia was predominant in both genders (male: 26.8%; female: 21.1%), as normocytic and normochromic anemia, with no anisocytosis (69.75%). Anemia was associated with thinness (PR: 1.68; 95% CI: 1.04–2.72) and with moderate (PR: 1.98; 95% CI: 1.07–3.63) and total (PR: 2.61; 95% CI: 1.34–5.07) dependence in the final model. Severe dependence exhibited borderline significance (PR: 1.94; 95% CI: 1.00–3.77). The prevalence of anemia was high in the institutionalized elderly in both genders, with characteristics suggesting chronic diseases as the causal factor, and the frequency of occurrence was higher in thinness elderly with moderate to total dependence.

    Iron deficiency anemia is a hypochromic anemia in which hemoglobin poor synthesis is due to a decrease in the amount of iron in the body. The decrease of iron quantity has many causes: insufficient intake of aliments rich in iron (meat, viscera, green vegetables), increased necessities during growth period, pregnancy, erythrocytes hyperregeneration, high-performance sportsmen, increased loss by digestive way, genito-urinary way, respiratory, hemorrhagic syndromes. Clinically, symptoms and signs specific to all types of anemia and those specific to lack of iron occur besides the symptoms and signs of the underlying disease: atrophic glositis, angular stomatitis, sideropenic dysphagia, pica, skin and nails changes. Laboratory investigations useful for diagnosis are: microcytic, hypochromic anemia, decreased serum iron level, total capacity of iron binding increased, medullar iron store absent, good response to iron therapy. Ferro-Folgamma is one of the most indicated medicines in iron deficiency anemia. Due to its components this medicine has many indications: insufficient alimentary intake concerning iron, folic acid, B12 vitamin, vegetarian alimentation, increased needs during growth period, iron deficiency anaemia secondary to chronic hemorrhages, malnutrition, anemias associated with chronic alcohol intake, preventive treatment of iron deficiency anemia and megaloblastic anemia during pregnancy and lactation.

    Isabela Martins Benseñor

    Full Text Available CONTEXT AND OBJECTIVES: Quantification of clinical signs such as the presence or absence of pallor at clinical examination is a key step for making diagnoses. The aim was, firstly, to evaluate two methods for anemia diagnosis by physical examination: four-level evaluation (crosses method: +/++/+++/++++ and estimated hemoglobin values, both performed by medical students and staff physicians; and secondly, to investigate whether there was any improvement in assessment accuracy according to the number of years in clinical practice. DESIGN AND SETTING: Forty-four randomly selected physicians and medical students in a tertiary care teaching hospital completed a physical examination on five patients with mild to severe anemia. METHODS: The observers used four-level evaluation and also predicted the hemoglobin level. Both methods were compared with the real hemoglobin value as the gold standard. RESULTS: The mean estimated hemoglobin value correlated better with the real hemoglobin values than did the four-level evaluation method, for attending physicians, residents and students (Spearman's correlation coefficients, respectively: 1.0, 1.0 and 0.9 for guessed hemoglobin and -0.8, -0.8 and -0.7 for the four-level evaluation method. There were no differences in the mean "guessed" hemoglobin values from attending physicians, residents and students. However, the correlation between guessed hemoglobin value and the four-level method was positive for attending physicians, thus suggesting some kind of improvement with time (p = 0.04. CONCLUSIONS: This study showed that estimated hemoglobin was more accurate than evaluation by the four-level method. The number of years in clinical practice did not improve the accuracy of clinical examination for anemia.

  18. Iron, anemia and hepcidin in malaria

    Directory of Open Access Journals (Sweden)

    Natasha eSpottiswoode

    2014-05-01

    Full Text Available Malaria and iron have a complex but important relationship. Plasmodium proliferation requires iron, both during the clinically silent liver stage of growth and in the disease-associated phase of erythrocyte infection. Precisely how the protozoan acquires its iron from its mammalian host remains unclear, but iron chelators can inhibit pathogen growth in vitro and in animal models. In humans, iron deficiency appears to protect against severe malaria, while iron supplementation increases risks of infection and disease. Malaria itself causes profound disturbances in physiological iron distribution and utilization, through mechanisms that include hemolysis, release of heme, dyserythropoiesis, anemia, deposition of iron in macrophages, and inhibition of dietary iron absorption. These effects have significant consequences. Malarial anemia is a major global health problem, especially in children, that remains incompletely understood and is not straightforward to treat. Furthermore, the changes in iron metabolism during a malaria infection may modulate susceptibility to coinfections. The release of heme and accumulation of iron in granulocytes may explain increased vulnerability to non-typhoidal Salmonella during malaria. The redistribution of iron away from hepatocytes and into macrophages may confer host resistance to superinfection, whereby blood-stage parasitemia prevents the development of a second liver-stage Plasmodium infection in the same organism. Key to understanding the pathophysiology of iron metabolism in malaria is the activity of the iron regulatory hormone hepcidin. Hepcidin is upregulated during blood-stage parasitemia and likely mediates much of the iron redistribution that accompanies disease. Understanding the regulation and role of hepcidin may offer new opportunities to combat malaria and formulate better approaches to treat anemia in the developing world.

    Uncompensated autoantibody-mediated red blood cell (RBC) consumption is the hallmark of autoimmune hemolytic anemia (AIHA). Classification of AIHA is pathophysiologically based and divides AIHA into warm, mixed or cold-reactive subtypes. This thermal-based classification is based on the optimal autoantibody-RBC reactivity temperatures. AIHA is further subcategorized into idiopathic and secondary with the later being associated with a number of underlying infectious, neoplastic and autoimmune disorders. In most cases AIHA is confirmed by a positive direct antiglobulin test (DAT). The standard therapeutic approaches to treatment of AIHA include corticosteroids, splenectomy, immunosuppressive agents and monoclonal antibodies.

    Full Text Available Thiamine responsive megaloblastic anemia (TRMA is an autosomal recessive disorder, which is caused by loss of function mutations in the SLC19A2 gene. TRMA is characterized by anemia, deafness, and diabetes mellitus. We now report two sisters, the eldest of which presented to a different hospital during childhood with sensorineural deafness, which was treated with a hearing prosthesis, insulin requiring diabetes, megaloblastic anemia. The younger sister is also affected with sensorineural deafness along with diabetes and megaloblastic anemia. Because a diagnosis of TRMA was suspected, therapy with insulin and thiamine was started to which the child is responding. Diabetes associated with deafness and megaloblastic anemia, suggests a diagnosis of TRMA.

    Full Text Available Ravish Shah, Anil K AgarwalDivision of Nephrology, The Ohio State University, Columbus, Ohio, USAAbstract: Anemia is a frequent comorbidity of heart failure and is associated with poor outcomes. Anemia in heart failure is considered to develop due to a complex interaction of iron deficiency, kidney disease, and cytokine production, although micronutrient insufficiency and blood loss may contribute. Currently, treatment of anemia of heart failure lacks clear targets and specific therapy is not defined. Intravenous iron use has been shown to benefit anemic as well as nonanemic patients with heart failure. Treatment with erythropoietin-stimulating agents has been considered alone or in combination with iron, but robust evidence to dictate clear guidelines is not currently available. Available and emerging new agents in the treatment of anemia of heart failure will need to be tested in randomized, controlled studies.Keywords: anemia, heart failure, chronic kidney disease, elderly population

    In this study, a patient who was hospitalized with a severe anemia in the Internal Medicine Clinic of the Health Research and Application Hospital of Yüzüncü Yil University for one week is presented. The patient had fatigue, paleness and dizziness for one month and approximately 12 kg weight lost for four mounts previous to admission.. Severe iron deficiency anemia was diagnosed in the patient by laboratory analyses. Because there were no hematologic factors associated with severe anemia, the stool examination was also performed. In the Parasitology Laboratory, stool microscopy of the patient revealed numerous ova of hookworm. General condition of the patient well improved with anti-parasitic and anti-anemia treatment. It was concluded that patients with iron deficiency anemia diagnosed in health centers should be also examined for the intestinal parasitic diseases encountered rarely, and physicians should consider non-endemic parasitic diseases in their provinces.

    This study evaluated the association between anemia and physical functional capacity in a cross-sectional population-based sample of 709 hospitalized elderly patients aged 60 years and over admitted to the Madre Teresa Hospital, Belo Horizonte, State of Minas Gerais, Brazil. The Mann-Whitney or "t" test, and chi-square or Fisher exact test were used for quantitative and categorical variables, respectively, and hierarchical binary logistic regression was used to identify significant predictors. The presence of anemia was found in 30% of participants and was significantly associated with decreased functionality according to the two measures which were used - ADL (activities of daily living) and IADL (instrumental activities of daily living). Anemia was also independently associated with older age. The results of this study demonstrate a strong association between the presence of anemia and lower levels of functional capacity. Further investigations are needed to assess the impact of anemia treatment on the functionality and independence of older people.

    The pathogenesis of anemia was studied in trypanosome-infected mice. A strain of Trypanosoma brucei, TREU 667, was used which first produces an acute phase marked by waves of parasitemia. Erythrocytes from infected animals were coated with immunoglobulin M during or just before the waves of anemia and parasitological crises. Erythrocytes from normal animals could be sensitized with "precrisis" sera presumably containing antigen and antibody. These data suggest that anemia during the acute phase is due to sensitization of erythrocytes with immunoglobulin M-antigen complexes. The anemia is partially compensated by a strong erythropoietic response. The acute phase is followed by a chronic phase marked by a constant high parasitemia and immunosuppression. The less marked anemia occurring during this latter phase is due to hemodilution and perhaps a low but significant immune response to the parasites, which causes continuing erythrocyte sensitization by immunoglobulin M-antigen complexes.

    Iron deficiency is the most common cause of anemia in pregnancy. Pregnant women with anemia are, in general, exclusively treated with iron supplementation. We observed that several pregnant women with anemia who were nonresponsive to iron supplementation also had vitamin B6 deficiency, and that anemia in these cases improved with the administration of vitamin B6. Our prospective study in healthy pregnant women showed that blood levels of iron, ferritin and vitamin B6, in particular, fell to the lower limit of the nonpregnant reference range by the third trimester. We conclude that it is important to take into account the deficiency of vitamin B6 besides iron in the evaluation of anemia during pregnancy.

    Full Text Available Flow cytometric reticulocyte analysis allows the evaluation of reticulocyte maturity. New reticulocyte parameters have been used in the diagnosis and management of anemias, in the bone marrow transplant setting and in the monitoring of iron replacement or erythropoiet in therapy. Reticulocyte numbers and maturation levels have been studied in different hemoglobinopathies and the results have been correlated with the degree of ineffective erythropoiesis. In order to verify differences in reticulocyte parameters in various types of anemias and to test the absolute number of immature reticulocytes as a possible discriminating factor among various types of anemias, reticulocyte counts were performed on 219 samples from patients with sickle cell anemia (SS (n= 62, hemoglobin S trait (n=9, Sbeta thalassemia (n=7, hemoglobin SC disease (n=11, beta thalassemia trait (n=33 and iron deficiency anemia (n= 47, and non-anemic individuals (n= 50. Mean fluorescence index (MFI was defined as representative of the degree of reticulocyte immaturity and it was evaluated as a percentage and in absolute values. Reticulocyte counts and MFI values were significantly higher in SS, Sbeta thalassemic and SC groups when compared to controls, but not different among the three anemia groups. Patients with hemoglobin S trait, iron deficiency anemia and beta thalassemia trait showed reticulocyte parameters similar to the non-anemic group. There was no difference between the b thalassemic trait and iron deficiency anemia in relation to any parameters. MFI in absolute numbers were significantly higher in anemias that develop with the hemolytic process, although this was not evident in MFI percentage values. Our results showed that the erythoid expansion in sickle cell diseases (SS, SC and Sb thalassemia leads to an enhanced immature reticulocyte release from bone marrow and that the phenomena is more evident by the MFI counting in absolute figures than in percentages.

    Full Text Available ABSTRACT OBJECTIVE: To evaluate socio-economic and demographic determinants of anemia among Indian children aged 6-59 months. METHODS: Statistical analysis was performed on the cross-sectional weighted sample of 40,885 children from 2005 to 2006 National Family Health Survey by using multinomial logistic regression to assess the significance of some risk factors in different degrees of child anemia. Anemia was diagnosed by World Health Organization (WHO cut-off points on hemoglobin level. Pearson's chi-squared test was applied to justify the associations of anemia with different categories of the study population. RESULTS: The prevalence of anemia was 69.5%; 26.2% mild, 40.4% moderate, and 2.9% severe anemia. Overall prevalence rate, along with mild and moderate cases, showed an increasing trend up to 2 years of age and then decreased. Rural children had a higher prevalence rate. Of 28 Indian states in the study, 10 states showed very high prevalence, the highest being Bihar (77.9%. Higher birth order, high index of poverty, low level of maternal education, mother's anemia, non-intake of iron supplements during pregnancy, and vegetarian mother increased the risks of all types of anemia among children (p < 0.05. Christian population was at lower risk; and Scheduled Caste, Scheduled Tribe, and Other Backward Class categories were at higher risk of anemia. CONCLUSION: The results suggest a need for proper planning and implementation of preventive measures to combat child anemia. Economically under-privileged groups, maternal nutrition and education, and birth control measures should be priorities in the programs.

    2004-12-01

    Thirty patients with a wide range of sore mouth that led to the diagnosis of iron deficiency in 12 patients, pernicious anemia in 8 patients, combined deficiency of iron and vitamin B12 in 2 patients, and anemia of chronic disease in 8 patients were investigated. The oral signs and symptoms included glossitis, glossodynia, angular cheilitis, recurrent oral ulcer, oral candidosis, diffuse erythematous mucositis, and pale oral mucosa. The values of hemoglobin in 30 patients varied from normal to severe life-threatening levels, but none had developed generalized symptoms sufficiently advanced to arouse suspicions of anemia before they visited the Oral Medicine Clinic. The aim of this paper is to describe a retrospective study of 30 patients with oral changes as the initial manifestation of nutritional deficiency or anemia of chronic diseases. Improved diagnosis and classification of anemia based on the mean and heterogeneity of red cell size will be discussed.

  14. Microfluidic approach of Sickled Cell Anemia

    2012-11-01

    Sickle Cell Anemia is a disorder of the microcirculation caused by a genetic point mutation that produces an altered hemoglobin protein called HbS. HbS self-assembles reversibly into long rope like fibers inside the red blood cells. The resulting distorded sickled red blood cells are believed to block the smallest capillaries of the tissues producing anemia. Despite the large amount of work that provided a thorough understanding of HbS polymerization in bulk as well as in intact red blood cells at rest, no consequent cellular scale approaches of the study of polymerization and its link to the capillary obstruction have been proposed in microflow, although the problem of obstruction is in essence a circulatory problem. Here, we use microfluidic channels, designed to mimic physiological conditions (flow velocity, oxygen concentration, hematocrit...) of the microcirculation to carry out a biomimetic study at the cellular scale of sickled cell vaso-occlusion. We show that flow geometry, oxygen concentration, white blood cells and free hemoglobin S are essential in the formation of original cell aggregates which could play a role in the vaso-occlusion events.

    An autopsy case of erythremia with sideroblastic tumor cell proliferation is described. A 60-year-old man was admitted to the hospital due to general fatigue and anorexia. Bone marrow aspiration revealed abnormalities in erythropoiesis (megaloblasts, 4%; sideroblasts, 84%; ring-formed, 39%, and PAS-positive, 5%). Therapy was directed to pulmonary tuberculosis. Anemia was not improved despite repeated whole blood and platelet transfusions. Serum iron and percentage saturation of the total iron-binding capacity rose during the course. Administration of vitamin B12, B6 or folic acid was inefffective. INAH was replaced by its derivative, IHMS, during the course, but the population of sideroblasts especially of ring-sideroblasts was invariably large (78%-100% and 39%-65% for total sideroblasts and ring-sideroblasts, respectively). He died with increasing abdominal pain and jaundice after three months' hospitalization. Main autopsy findings were: diffuse proliferation of atypical erythroblasts in the bone marrow, systemic lymph nodes, liver, spleen and kidneys. Most of the cells positively stained with iron. Tuberculosis of lungs with cavity formation. Discussion is focussed on the relationship between erythremia and sideroblastic anemia.

    Full Text Available Introduction. Cameron lesions are linear gastric ulcers or erosions positioned on the crests of mucosal folds at the diaphragmatic impression, in patients with large hiatal hernia, and can cause iron deficiency anaemia. Case report. We present a case of a 56-year-old woman who was referred to our institution for further investigation after she was examined in gastroenterology emergency room (GER for signs and symptoms of severe hypochromic microcytic anemia without signs of acute gastrointestinal bleeding and with no obvious cause of chronic blood loss. Endoscopy showed linear ulceration at the level of diaphragm-Cameron lesions with large hiated hernia. She was treated with proton pump inhibitors and iron supplements. The laparoscopic fundoplication was done. Six months later she was asymptomatic. Conclusion. Large hiatus hernia may cause iron deficiency anemia due to occult bleeding from Cameron erosions. The current therapy concept includes the surgical reconstruction of the hiatus together with gastric fundoplication in combination with the proton pump inhibitor therapy.

    This study was conducted to determine the optimum dose of supplemental iron for prophylaxis against pregnancy anemia. One hundred and ten pregnant women were randomly allocated to three groups: Group A receiving equivalent of 60 mg, group B 120 mg and Group C 240 mg, elemental iron as ferrous sulphate daily; the content of folic acid was constant in all the three groups (0.5 mg). These women had at least consumed 90 tablets in 100 +/- 10 days. Blood was drawn at the beginning and at the end of the treatment. Fifty percent were anemic (less than 11 g/100 ml). The hemoglobin levels rose similarly in all groups and the differences were statistically not significant. Fifty-six percent had depleted iron stores (serum ferritin value less than 12 micrograms/l) at the beginning of the study. Following therapy a statistically significant increase in iron stores was observed in group B and C as compared to group A. The difference between group B and C was not significant. The side effects increased with increasing doses of iron; 32.4%, 40.3% and 72% in group A, B and C respectively. Based on these findings, the authors advocate that optimum dose of iron should be 120 mg instead of 60 mg as is currently being used in the National Nutritional Anemia Prophylaxis Programme.

    Full Text Available Warm autoimmune hemolytic anemia (WAIHA is one of four clinical types of autoimmune hemolytic anemia (AIHA, with the characteristics of autoantibodies maximally active at body temperature. It produces a variable anemia—sometimes mild and sometimes severe. With respect to the absence or presence of an underlying condition, WAIHA is either idiopathic (primary or secondary, which determines the treatment strategies in practice. Conventional treatments include immune suppression with corticosteroids and, in some cases, splenectomy. In recent years, the number of clinical studies with monoclonal antibodies and immunosuppressants in the treatment of WAIHA increased as the knowledge of autoimmunity mechanisms extended. This thread of developing new tools of treating WAIHA is well exemplified with the success in using anti-CD20 monoclonal antibody, Rituximab. Following this success, other treatment methods based on the immune mechanisms of WAIHA have emerged. We reviewed these newly developed immunotherapy treatments here in order to provide the clinicians with more options in selecting the best therapy for patients with WAIHA, hoping to stimulate researchers to find more novel immunotherapy strategies.

    Full Text Available Melca M O Barros, Dante M Langhi Jr, José O Bordin Department of Clinical and Experimental Oncology, Universidade Federal de São Paulo, São Paulo, Brazil Abstract: Autoimmune hemolytic anemia (AIHA is defined as the increased destruction of red blood cells (RBCs in the presence of anti-RBC autoantibodies and/or complement. Classification of AIHA is based on the optimal auto-RBC antibody reactivity temperatures and includes warm, cold-reactive, mixed AIHA, and drug-induced AIHA subtypes. AIHA is a rare disease, and recommendations for transfusion are based mainly on results from retrospective data and relatively small cohort studies, including heterogeneous patient samples or single case reports. In this article, we will review the challenges and solutions to safely transfuse AIHA patients. We will reflect on the indication for transfusion in AIHA and the difficulty in the accomplishment of immunohematological procedures for the selection of the safest and most compatible RBC units.

    Full Text Available Anemia de Doença Crônica (ADC é usualmente definida como a anemia que ocorre em distúrbios infecciosos crônicos, inflamatórios ou doenças neoplásicas, e é uma das síndromes clínicas mais comuns na prática clínica. Caracteristicamente, ADC corresponde à anemia normocrômica/normocítica, leve a moderada, e caracteriza-se por hipoferremia na presença de estoques adequados de ferro. Os três principais mecanismos patológicos envolvidos na ADC são: diminuição da sobrevida da hemácia, falha da medula óssea em aumentar a produção de glóbulos vermelhos para compensar o aumento da sua demanda, e distúrbio da mobilização do ferro de depósito do sistema mononuclear fagocitário. O papel central dos monócitos e dos macrófagos e o aumento da produção de citocinas mediadoras da resposta imune ou inflamatória, tais como: TNF alfa, INF gama e IL-1 estão implicados nos três processos envolvidos no desenvolvimento da ADC. O propósito desse artigo é revisar os recentes avanços no entendimento dos aspectos patofisiológico, diagnóstico e terapêutico desta síndrome.The anemia of chronic disease (ACD is usually defined as the anemia occurring in chronic infectious, inflammatory disorders, or neoplastic diseases, and is one of the most common syndromes in the clinical practice. Characteristically, ACD is a mild-to-moderate, normochromic/normocytic anemia, and is characterized by hypoferremia in the presence of adequate iron stores. The three principal pathologic mechanisms involved in ACD are: reduced erythrocyte survival, bone marrow failure to increase red blood cell production to compensate for the increase in its demand, and abnormal mobilization of reticuloendothelial iron stores. The central role of monocytes and macrophages, and the increased production of the cytokines that mediate the immune or inflammatory response, such as tumor necrosis factor, interleukin-1 and the interferons, are implicated in all three

    objectives To demonstrate the phenomena and explore the causes of anemia in patients with chronic heart failure (CHF). Methods To observe the phenomena of anemia in patients with CHF, a total of 276 patients with CHF were included in this retrospective study. The clinical characteristics of the patients are: mean age 69.2±11.0 years; male 151,female 125; NYHA Ⅲ and Ⅳ 115 (41.7%). Results ①Among the 276 patients with CHF, 81 (29.4%)had anemia (Mean hemoglobulin concentration 101.5±13.0g/L). ② Patients with Anemia were more likely to be female and to have greater NYHA (Ⅲ or Ⅳ) (P<0.05), higher serum creatinine, as well as lower serum albumin and low-density lipoprotein levels (P<0.01).③ A weak negative correlation was also noted between the level of NYHA and hemoglobulin. ④ There was no significant difference in age, the primary cardiac etiology of the CHF, the history of diabetes, left ventricular end diastolic diameter, and left ventricular ejection fraction between CHF patient with and without anemia. Conclusions The prevalence of anemia is high among patients with CHF. The anemia patients with CHF tend to be female, have greater cardiac and renal functional impairment, but with lower serum albumin and LDL that suggests some degree of malnutrition.

    Anemia is a frequent complication in patients with inflammatory bowel disease (IBD), and is associated with decreased quality of life and increased rate of hospitalization. The primary therapeutic targets of IBDassociated anemia are iron deficiency and anemia of chronic disease. An important prognostic parameter of the success or failure of therapy is the outcome of the underlying disease. Iron deficiency should be appropriately managed with iron supplementation.However, the use of oral iron therapy is limited by several problems, the most important being gastrointestinal side effects leading occasionally to disease relapse and poor iron absorption. Intravenous iron preparations are more reliable, with iron sucrose demonstrating the best efficacy and tolerability. Treatment with erythropoietin or darbepoetin has been proven to be effective in patients with anemia, who fail to respond to intravenous iron. Patients with ongoing inflammation have anemia of chronic disease and may require combination therapy comprising of intravenous iron sucrose and erythropoietin. After initiating treatment, careful monitoring of hemoglobin levels and iron parameters is needed in order to avoid recurrence of anemia. In conclusion, anemia in the setting of IBD should be aggressively diagnosed, investigated, and treated. Future studies should define the optimal dose and schedule of intravenous iron supplementation and appropriate erythropoietin therapy in these patients.

    The objective of this study was to assess the prevalence of anemia and iron deficiency (ID) of a nationally representative sample of the Kuwait population. We also determined if anemia differed by socioeconomic status or by RBC folate and vitamins A and B12 levels. The subjects who were made up of 1830 males and females between the ages of 2 months to 86 years, were divided into the following age groups (0-5, 5-11, 12-14, 15-19, 20-49, ≥50 years). Results showed that the prevalence of anemia was 3% in adult males and 17% in females. The prevalence of ID varied according to age between 4% (≥50 years) and 21% (5-11 years) and 9% (12-14 years) and 23% (15-19 years), respectively, in males and females. The prevalence of anemia and ID was higher in females compared to males. Adults with normal ferritin level, but with low RBC folate and vitamins A and B12 levels had higher prevalence of anemia than those with normal RBC folate and vitamins A and B12 levels. This first nationally representative nutrition and health survey in Kuwait indicated that anemia and ID are prevalent and ID contributes significantly to anemia prevalence.

    Full Text Available Sideroblastic anemia, comprising of acquired and congenital forms, is a heterogeneous group of disorders characterized by the presence of ring sideroblasts in the bone marrow. Congenital sideroblastic anemia is a rare condition which is mostly X-linked, caused by mutations of delta-aminolevulinic acid synthase 2. We describe two cases of congenital sideroblastic anemia, one of them indicating an autosomal recessive inheritance, with their clinico-hematological profile. It is important to recognize this entity early in life as a significant percentage of cases respond to pyridoxine thus avoiding any long-term complications.

  11. [New insights on hepcidin in anemia of chronic disease].

    2009-12-01

    Anemia of chronic disease is normocytic and normochromic. One of the mechanisms is misbalance of iron metabolism. Hepcidin, a kind of protein secreted by liver is considered to be the hormone regulating iron metabolism. It binds to ferroportin and induces the latter one's internalization. Thus, iron transportation from iron storage cells to serum is reduced. Cytokines are elevated in chronic disease. They stimulate hepcidin expression in liver through JAK2/STAT3 pathway. As a result, iron absorption and reabsorption is blocked, which leads to the misbalance of iron metabolism in anemia of chronic disease. In this article, the hepcidin and its relation to iron metabolism and anemia in chronic disease are reviewed.

    Full Text Available O objetivo deste estudo de revisão bibliográfica é fornecer subsídios para o planejamento e avaliação de medidas de combate à anemia ferropriva. A necessidade de intervenções para o controle da prevalência da anemia ferropriva deve ser determinada pela magnitude da defi ciência nutricional e pelo conhecimento de seus efeitos na qualidade de vida, morbidade e mortalidade. A abordagem mais usual é fornecer ferro suplementar a gestantes, nutrizes e lactentes em programas de assistência primária à saúde, reconhecidamente os grupos de maior vulnerabilidade. A fortificação de alimentos e orientações sobre modificações da dieta representam medidas complementares e devem ser incrementadas.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.

  13. Assessing Chaos in Sickle Cell Anemia Crises

    2006-11-01

    Recent developments in sickle cell research and blood flow modeling allow for new interpretations of the sickle cell crises. With an appropriate set of theoretical and empirical equations describing the dynamics of the red cells in their environment, and the response of the capillaries to major changes in the rheology, a complete mathematical system has been derived. This system of equations is believed to be of major importance to provide new and significant insight into the causes of the disease and related crises. With simulations, it has been proven that the system transition from a periodic solution to a chaotic one, which illustrates the onset of crises from a regular blood flow synchronized with the heart beat. Moreover, the analysis of the effects of various physiological parameters exposes the potential to control chaotic solutions, which, in turn, could lead to the creation of new and more effective treatments for sickle cell anemia. .

    Labie, D

    1992-10-01

    The genetics of sickle cell anemia may be considered as a model. Its mendelian transmission was hypothesized even before the molecular era. Once the mutation identified, it could be studied at the protein and DNA level; a consistent pathophysiological mechanism was proposed; the various genetic forms of the disease could be identified; the way by which a balanced polymorphism with Plasmodium falciparum malaria is obtained was analyzed. More recently, investigations were run in order to understand how modulating, or epistatic factors could modify the pathophysiological mechanism and contribute to the high clinical diversity of the disease. Several factors have been identified, among which a concomitant alpha-thalassemia, an overproduction of fetal hemoglobin, due either to an activation of the gamma genes or to an increase of the F-cell number, and finally a quantitative control of the beta s chains themselves. Such a high number of genetic active factors questions the concept itself of a monogenic disease.

    The congenital dyserythropoietic anemias (CDAs) are a heterogeneous group of genetic disorders of red cell production. They are characterized by ineffective erythropoiesis and dyserythropoiesis. Here, we present the clinical description and mutation analysis of a Japanese female with CDA type 1. She has long been diagnosed with unclassified congenital hemolytic anemia from the neonatal period. However, bone marrow morphology and genetic testing of the CDAN1 gene at the age of 12 years confirmed the afore-mentioned diagnosis. Thus, we should be aware of the possibility of CDA if the etiology of congenital anemia or jaundice cannot be clearly elucidated.

    Full Text Available A hipertensão pulmonar é uma complicação comum em pacientes com anemia falciforme. A despeito das elevações leves das pressões pulmonares desses pacientes, a morbimortalidade é alta e, em pacientes adultos com anemia falciforme, a hipertensão pulmonar é um fator de risco muito importante. A patogênese da hipertensão pulmonar relacionada à anemia falciforme é multifatorial e inclui hemólise, baixos níveis de óxido nítrico, hipóxia crônica, tromboembolismo, doença hepática crônica e asplenia. Na maioria dos pacientes, a hipertensão arterial pulmonar é a causa principal para as elevações na pressão arterial pulmonar, mas a hipertensão pulmonar venosa também é um fator contribuinte em alguns pacientes. Existem poucos estudos específicos avaliando os efeitos de tratamento para a hipertensão pulmonar em pacientes com anemia falciforme. É provável que a intensificação da terapia para a anemia hemolítica em todos os pacientes e o tratamento específico para a hipertensão pulmonar em pacientes com doença severa sejam benéficos. Estudos de grande porte avaliando o efeito do tratamento da hipertensão pulmonar em pacientes com anemia falciforme estão em andamento.Pulmonary hypertension is a common complication of sickle cell anemia. Despite the fact that the elevations in pulmonary artery pressures are slight, morbidity and mortality are high. In adult sickle cell anemia patients, pulmonary hypertension is emerging as a major risk factor for death. The pathogenesis of sickle cell anemia-related pulmonary hypertension is multifactorial, including hemolysis, impaired nitric oxide bioavailability, chronic hypoxemia, thromboembolism, chronic liver disease and asplenia. In the majority of patients, pulmonary arterial hypertension is the main cause of elevated pulmonary artery pressures. However, pulmonary venous hypertension also plays a role in a subgroup of patients. Specific data on the effects of treatment

    Introducción: la anemia gestacional todavía se considera un problema de salud pública en Brasil y se asocia con un mayor riesgo de morbilidad materno-fetal y el estado nutricional de los niños en el período posparto. Objetivo: evaluar la frecuencia de la anemia gestacional materna en recién nacidos y su relación con el estado nutricional del niño al nacer. Métodos: se obtuvieron datos antropométricos de las mujeres embarazadas y los recién nacidos. Se recogieron muestras de sangre de mujeres embarazadas y de cordón umbilical de los recién nacidos para su posterior análisis de hemoglobina, hematocrito, ADE, hierro, ferritina e índice de saturación de transferrina en dispositivos automatizados. Los resultados se presentan como media y la desviación estándar. Fue utilizado el software GraphPadinStat®, versión 3.0 y se aceptó un nivel de significación del 5%. Resultados: la frecuencia de anemia materna era de 53,7% y 32,6% en los recién nacidos. La mitad de los recién nacidos eran niños anémicos de madres anémicas. De las mujeres embarazadas con anemia, el 79,3% tenían anemia leve y el 20,7% moderada. La concentración media de hemoglobina y hematocrito fue menor en las mujeres embarazadas con anemia (9,7 ± 0,9 g/ dl y 29,8 ± 3,2%) en comparación con las no anémicas (11,9 ± 0,7 g/dl y 36,5 ± 2,7%), como se esperaba. El nivel de hierro de la madre se correlacionó positivamente con ferritina (r = 0,389; p = 0,01) a partir de la sangre del cordón umbilical. El peso, la longitud y la circunferencia de la cabeza de los niños nacidos de madres anémicas fueron: 3.375,9 ± 506,9 g, 51,2 ± 1,7 cm y 34,5 ± 1,5 cm, respectivamente, mientras que entre los recién nacidos de madres no anémicas fueron: 3.300,2 ± 458,4 g, 50,3 ± 2,0 cm y 34,2 ± 2,0 cm, respectivamente. No se encontraron correlaciones significativas entre la hemoglobina, el hierro y la ferritina de la madre, y el peso, la longitud y la circunferencia de la cabeza de los reci

    2013-01-01

    Anemia is a frequent comorbidity of heart failure and is associated with poor outcomes. Anemia in heart failure is considered to develop due to a complex interaction of iron deficiency, kidney disease, and cytokine production, although micronutrient insufficiency and blood loss may contribute. Currently, treatment of anemia of heart failure lacks clear targets and specific therapy is not defined. Intravenous iron use has been shown to benefit anemic as well as nonanemic patients with heart failure. Treatment with erythropoietin-stimulating agents has been considered alone or in combination with iron, but robust evidence to dictate clear guidelines is not currently available. Available and emerging new agents in the treatment of anemia of heart failure will need to be tested in randomized, controlled studies.

    Full Text Available AIMS AND OBJECTIVE: To investigate possible association between Anemia and Gestational Diabetes Mellitus (GDM. DESIGN, SETTING & PARTICIPANTS: A cross sectional study comprising of 100 GDM patients attending as outpatients or In-patients at Vani Vilas hospital and Bowring & Lady Curzon hospital, BMC & RI, Bangalore. MAIN MEASUREMENTS: GDM patients either newly diagnosed or on follow up were selected and complete blood counts including the peripheral smear, blood sugar levels and HbA1c were done. RESULTS: Anemia was diagnosed in 6 patients (6% who are considerably less compared to Non-GDM pregnancy (40-50%. Out of which only 1 patient’s peripheral smear showed Microcytic hypochromic blood picture whereas rest showed Normocytic Normochromic picture. CONCLUSION: Our study suggests that incidence of Anemia especially Microcytic Hypochromic Anemia is considerably lower in GDM. These finding suggests that routine supplementation of Iron irrespective of Hemoglobin (Hb levels should be reconsidered in risk group women.

    Sex chromosome aneuploidies range in incidence from rather common to exceedingly rare and have a variable phenotype. We report 2 patients with sex chromosome aneuploidies who developed severe aplastic anemia requiring treatment. The first patient had tetrasomy X (48,XXXX) and presented at 9 years of age, and the second patient had trisomy X (47,XXX) and presented at 5 years of age. Although aplastic anemia has been associated with other chromosomal abnormalities, sex chromosome abnormalities have not been traditionally considered a risk factor for this condition. A review of the literature reveals that at least one other patient with a sex chromosome aneuploidy (45,X) has suffered from aplastic anemia and that other autosomal chromosomal anomalies have been described. Despite the uncommon nature of each condition, it is possible that the apparent association is coincidental. A better understanding of the genetic causes of aplastic anemia remains important.

    Full Text Available Hemolytic anemia is exceedingly rare and an underestimated complication after aortic valve replacement (AVR.The mechanism responsible for hemolysis most commonly involves a regurgitated flow or jet that related to paravalvar leak or turbulence of subvalvar stenosis. It appears to be independent of its severity as assessed by echocardiography. We present a case of a 24-year-old man with a history of AVR in 10 year ago that developed severe hemolytic anemia due to a mild subvalvar stenosis caused by pannus formation and mild hypertrophic septum. After exclusion of other causes of hemolytic anemia and the lack of clinical and laboratory improvement, the patient underwent redo valve surgery with pannus and subvalvar hypertrophic septum resection. Anemia and heart failure symptoms gradually resolved after surgery

    The gastrointestinal (GI) tract is a common site of bleeding that may lead to iron deficiency anemia (IDA). Treatment of IDA depends on severity and acuity of patients’ signs and symptoms. While red blood cell transfusions may be required in hemodynamically unstable patients, transfusions should be avoided in chronically anemic patients due to their potential side effects and cost. Iron studies need to be performed after episodes of GI bleeding and stores need to be replenished before anemia develops. Oral ...

    Full Text Available Anemia is a very common disorder both in clinical practice and in the community. The recent rise in the population of the elderly has become the focus of attention in developing countries, because of the increasing longevity of the elderly, whilst the prevalence of anemia increases with age. The objective of this study was to determine the prevalence of anemia and its association with the quality of life in the elderly. A cross-sectional study was conducted from April to June 2008, located in the Mampang Prapatan district, South Jakarta. A total of 298 elderly persons participated in this study, comprising 109 (36.6% males and 189 (63.4% females. Anemia was measured by the parameters of hemoglobin and quality of life was assessed by the WHOQOL-BREF instrument, a short version of the WHOQOL-100 instrument. The results of the study showed the prevalence of anemia to be 26.2%, with a higher prevalence rate in females compared with males. The quality of life in the physical, psychological, social and environmental domains differed significantly with decreasing hemoglobin levels, whereas the physical and mental quality of life declined significantly with age. Anemia is thus indicative of a reduction in the quality of life of the elderly.

    Full Text Available The aim of this paper is to review the literature and identify orofacial manifestations of hematological diseases, with particular reference to anemias and disorders of hemostasis. A computerized literature search using MEDLINE was conducted for published articles on orofacial manifestations of hematological diseases, with emphasis on anemia. Mesh phrases used in the search were: oral diseases AND anaemia; orofacial diseases AND anaemia; orofacial lesions AND anaemia; orofacial manifestations AND disorders of haemostasis. The Boolean operator "AND" was used to combine and narrow the searches. Anemic disorders associated with orofacial signs and symptoms include iron deficiency anemia, Plummer-Vinson syndrome, megaloblastic anemia, sickle cell anemia, thalassaemia and aplastic anemia. The manifestations include conjunctiva and facial pallor, atrophic glossitis, angular stomatitis, dysphagia, magenta tongue, midfacial overgrowth, osteoclerosis, osteomyelitis and paraesthesia/anesthesia of the mental nerve. Orofacial petechiae, conjunctivae hemorrhage, nose-bleeding, spontaneous and post-traumatic gingival hemorrhage and prolonged post-extraction bleeding are common orofacial manifestations of inherited hemostatic disorders such as von Willebrand′s disease and hemophilia. A wide array of anemic and hemostatic disorders encountered in internal medicine has manifestations in the oral cavity and the facial region. Most of these manifestations are non-specific, but should alert the hematologist and the dental surgeon to the possibilities of a concurrent disease of hemopoiesis or hemostasis or a latent one that may subsequently manifest itself.

    Patients surviving sepsis develop anemia but the molecular mechanism is unknown. Here we observed that mice surviving polymicrobial Gram-negative sepsis develop hypochromic, microcytic anemia with reticulocytosis. The bone marrow of sepsis survivors accumulates polychromatophilic and orthochromatic erythroblasts. Compensatory extramedullary erythropoiesis in the spleen is defective during terminal differentiation. Circulating TNF and IL-6 are elevated for five days after the onset of sepsis, and serum HMGB1 levels are increased from day seven until at least day 28. Administration of recombinant HMGB1 to healthy mice mediates anemia with extramedullary erythropoiesis and significantly elevated reticulocyte counts. Moreover, administration of anti-HMGB1 monoclonal antibodies after sepsis significantly ameliorates the development of anemia (hematocrit 48.5±9.0% versus 37.4±6.1%, p<0.01, hemoglobin 14.0±1.7g/dL versus 11.7±1.2g/dL, p<0.01). Together, these results indicate that HMGB1 mediates anemia by interfering with erythropoiesis, suggesting a potential therapeutic strategy for anemia in sepsis.

    Full Text Available In some renal allograft recipients, anemia persists or develops following transplantation. Anemia is associated with pre-operative blood loss and allograft dysfunction, including delayed graft function, acute rejection and chronic allograft dysfunction. To study the prevalence and association of post-renal transplant anemia, we studied 200 renal transplant recipients; 131 (65.5% patients were males and 69 (34.5% patients were females, and age ranged from 17 to 67 years, with a mean of 37.7 ± 10.8 years. All patients were receiving cyclosporine, prednisolone and mycophenolate mofetil (MMF. Complete blood count was done at two times: three and six months post-renal transplant. There were 74% anemic patients three months after renal transplantation and 45% anemic patients six months after renal transplantation. High creatinine value, female gender, delayed graft function, episodes of acute rejection, perioperative blood loss and infections were the only significant independent risk factors for prevalence of anemia post-renal transplant. In our study, we did not find an association between MMF and cyclosporine nor angiotensin-converting enzyme inhibitors (ACEIs or angiotensin receptors blocker (ARBs with anemia. This study demonstrates that anemia is a common complication during the first six months after kidney transplantation, with several risk factors precipitating this complication.

    Anemia is common among young women, and iron deficiency is one of the leading causes. In Europe and the US, the iron fortification of flour increased oral iron intake and decreased anemia prevalence from 30% to 10%. The National Nutrition Survey in Japan revealed that anemia prevalence among young Japanese women is increasing; however, no nationwide preventive policy has been aimed at iron deficiency anemia. The endpoint of this study was the estimation of anemia prevalence among healthy Japanese woman, based on a large sample size. We collected data from the consecutive check-up examination records of apparently healthy women (n = 13,147). We defined hemoglobin lower than 12 g/dL as anemia, hemoglobin lower than 10 g/dL as severe anemia, and a mean corpuscular volume lower than 80 fl as microcytic anemia. Of the 13,147 persons, anemia was identified in 2331 (17.3 %), and severe and microcytic anemia in 438 (3.3 %) and 700 (5.2 %), respectively. Among women younger than 50 years, anemia was identified in 22.3 %, and 25.2 % of them had severe anemia. In conclusion, the prevalence of anemia and severe anemia among young women is high in Japan. Some action needs to be considered to improve women's quality of life.

Acomete geralmente adultos jovens e idosos, sem preferência sexual. A maioria dos casos é adquirida, mas pode ocorrer hereditariamente, por distúrbio molecular (anemia de Fanconi. A associação com gravidez é rara, estando relacionada com alta morbidade e mortalidade materna e fetal. Os autores descrevem o caso de uma paciente com anemia aplástica, diagnosticada previamente, cuja gestação complicou com infecção do trato urinário, doença hipertensiva específica da gestação e restrição de crescimento fetal, com parto prematuro eletivo. Apesar das condições adversas na gravidez e parto, mãe e recém-nascido tiveram evolução clínica satisfatória.Aplastic anemia is characterized by a circulating pancytopenia, hypocellularity, and fatty replacement of cellular marrow elements, without evidence of malignant transformation or myeloproliferative disease. It usually affects young and senior adults, without any sexual preference. Most cases of aplastic anemia are acquired, but the disease may also be inherited due to a molecular disorder (Fanconi's anemia. Aplastic anemia in pregnancy is an extremely rare condition with high maternal and fetal morbidity and mortality rates. The authors describe a case of a patient with previously diagnosed aplastic anemia, whose pregnancy was complicated with urinary tract infection, preeclampsia and fetal growth restriction, with elective preterm birth. In spite of the adverse conditions in pregnancy and delivery, mother and newborn had a satisfactory clinical evolution.

We investigate the diagnostic value of erythrocyte indices, red cell volume distribution width, and serum ferritin levels to make differential diagnosis of anemia in controls and anemic patients.Iron deficiency anemia (44 patients, anemia of chronic disease (41, IDA with anemia of chronic disease (17 and control (50 groups were compared. We performed serum ferritin, CBC, and sedimentation rate in all patientsand bone marrow aspiration in patients with anemia of chronic disease.Although mean cell volume (MCV and mean corpuscular hemoglobin (MCH are low in IDA and anemia of chronic disease, it is much striking in the former one (p<0.001, p<0.001. Only 7.3% of patients with anemia of chronic disease had a MCV<70 fL and MCH<24 pg, 90.0% of patients with IDA were below that cut-off point. Serum ferritin means were in patients with IDA and anemia of chronic disease were 4.6±3.3 and 489.6 ±519.9 ng/ml, respectively.The probability of IDA is low when RDW is normal in microcytic anemias. RDW is high in half of patients with anemia of chronic disease. Reference values for ferritin must be changed in patients with anemia of chronic disease and IDA. If serum ferritin is 57.6-146.4 ng/ml anemia of chronic disease and iron deficiency must ruled out by other diagnostic tests.

This clinic was set up to provide diagnosis and treatment, and to coordinate investigative procedures, where necessary, into the underlying causes of anemia. Initially piloted with anemic preoperative orthopedic patients, the clinic now treats a wide range of conditions, deriving from both internal and external referrals. Treatment includes dietary advice, supplementation with iron, vitamin B12 and folate, and blood transfusion. Most patients at the RAAC need iron replacement, the majority of which require intravenous (IV iron. Therefore the first-line IV iron-administration protocol is carefully considered to ensure viability of the service and patient satisfaction. Four IV irons available in the UK are discussed, with explanation of the benefits and drawbacks of each product and the reasoning behind the IV iron choice at different stages of the RAAC's development. Costs to the service, affected by IV iron price and administration regimen, are considered, as well as the product's contraindications. Finally, the authors reflect on the success of the RAAC and how it has improved patients' quality-of-treatment experience, in addition to benefiting the hospital and National Health Service in achieving specific health-care mandates and directives. Drawing from the authors' experiences, recommendations are given to assist others in setting up and providing a successful rapid-access anemia service or similar facility.Keywords: hemoglobin, iron deficiency, ferric carboxymaltose, iron sucrose, iron dextran, iron isomaltoside

  20. Genetic/metabolic effect of iron metabolism and rare anemias

    Full Text Available Advances in iron metabolism have allowed a novel classification of iron disorders and to identify previously unknown diseases. These disorders include genetic iron overload (hemochromatosis and inherited iron-related anemias, in some cases accompanied by iron overload. Rare inherited anemias may affect the hepcidin pathway, iron absorption, transport, utilization and recycling. Among the genetic iron-related anemias the most common form is likely the iron-refractory iron-deficiency anemia (IRIDA, due to mutations of the hepcidin inhibitor TMPRSS6 encoding the serine protease matriptase-2. IRIDA is characterized by hepcidin up-regulation, decrease iron absorption and macrophage recycling and by microcytic- hypochromic anemia, unresponsive to oral iron. High serum hepcidin levels may suggest the diagnosis, which requires demonstrating the causal TMPRSS6 mutations by gene sequencing. Other rare microcytic hypochromic anemias associated with defects of iron transport-uptake are the rare hypotransferrinemia, and DMT1 and STEAP3 mutations. The degree of anemia is variable and accompanied by secondary iron overload even in the absence of blood transfusions. This is due to the iron-deficient or expanded erythropoiesis that inhibits hepcidin transcription, increases iron absorption, through the erythroid regulator, as in untransfused beta-thalassemia. Sideroblastic anemias are due to decreased mitochondrial iron utilization for heme or sulfur cluster synthesis. Their diagnosis requires demonstrating ringed sideroblasts by Perl’s staining of the bone marrow smears. The commonest X-linked form is due to deltaamino- levulinic-synthase-2-acid (ALAS2 mutations. The recessive, more severe form, affects SLC25A38, which encodes a potential mitochondrial importer of glycine, an amino acid essential for ALA synthesis and thus results in heme deficiency. Two disorders affect iron/sulfur cluster biogenesis: deficiency of the ATP-binding cassette B7 (ABCB7 causes X

    Full Text Available INTRODUCTION: Sickle cell anemia and thalassemia result in impaired bone health in both adults and youths. Children with other types of chronic hemolytic anemia may also display impaired bone health. STUDY DESIGN: To assess bone health in pediatric patients with chronic hemolytic anemia, a cross-sectional study was conducted involving 45 patients with different forms of hemolytic anemia (i.e., 17 homozygous sickle cell disease and 14 hereditary spherocytosis patients. Biochemical, radiographic and anamnestic parameters of bone health were assessed. RESULTS: Vitamin D deficiency with 25 OH-vitamin D serum levels below 20 ng/ml was a common finding (80.5% in this cohort. Bone pain was present in 31% of patients. Analysis of RANKL, osteoprotegerin (OPG and osteocalcin levels indicated an alteration in bone modeling with significantly elevated RANKL/OPG ratios (control: 0.08+0.07; patients: 0.26+0.2, P = 0.0007. Osteocalcin levels were found to be lower in patients compared with healthy controls (68.5+39.0 ng/ml vs. 118.0+36.6 ng/ml, P = 0.0001. Multiple stepwise regression analysis revealed a significant (P<0.025 influence of LDH (partial r2 = 0.29, diagnosis of hemolytic anemia (partial r2 = 0.05 and age (partial r2 = 0.03 on osteocalcin levels. Patients with homozygous sickle cell anemia were more frequently and more severely affected by impaired bone health than patients with hereditary spherocytosis. CONCLUSION: Bone health is impaired in pediatric patients with hemolytic anemia. In addition to endocrine alterations, an imbalance in the RANKL/OPG system and low levels of osteocalcin may contribute to this impairment.

    Full Text Available INTRODUCTION: Sideropenic anemia is one of the most common nutritional disorders in the world. The children are at higher risk of iron deficiency than adults due to their rapid growth during infancy and relatively higher requirements of iron. OBJECTIVE: The objective of our study was to investigate the prevalence of sideropenic anemia in pre-school children and relevant risk factors. METHOD: Study on sideropenic anemia of preschool children was performed in Zaječar Municipality in 2003. Subjects: all children, age 6-7 years, who lived in the Zaječar Municipality (554 children. The investigation included: interview of children's parents and laboratory analysis of blood. RESULTS: The frequency of sideropenic anemia was 5.23% in tested children (hemoglobin level less than 11g/dl. Sex and place of residence had no significant impact on hemoglobin concentration in blood of children. Likewise, social status and education of parents had no significant impact on iron deficiency anemia. Higher incidence of infections was found in children with lower hemoglobin concentration in blood (p<0.05. It made no difference if children attended the kindergarten or not. Nutrition of children in kindergarten does not correct domestic nutrition, which should be one of its basic roles. CONCLUSION: Since sideropenic anemia gives rise to serious health problems, such as poor cognitive and motor development and behavioral problems, it is important to take corrective measures regarding domestic and social nutrition of children. Therefore, it is necessary to take action in preventing the sideropenic anemia and provide normal growth and development.

    Each of the thirteen identified Fanconi anemia (FA) genes is required for resistance to DNA interstrand crosslinking agents, such as mitomycin C, cisplatin, and melphalan. While these agents are excellent tools for understanding the function of FA proteins in DNA repair, it is uncertain whether a defect in the removal of DNA interstrand crosslinks (ICLs) is the basis for the pathophysiology of FA. For example, DNA interstrand crosslinking agents induce other types of DNA damage, in addition to ICLs. Further, other DNA-damaging agents, such as ionizing or ultraviolet radiation, activate the FA pathway, leading to monoubiquitination of FANCD2 and FANCI. Also, FA patients display congenital abnormalities, hematologic deficiencies, and a predisposition to cancer in the absence of an environmental source of ICLs that is external to cells. Here we consider potential sources of endogenous DNA damage, or endogenous stresses, to which FA proteins may respond. These include ICLs formed by products of lipid peroxidation, and other forms of oxidative DNA damage. FA proteins may also potentially respond to telomere shortening or replication stress. Defining these endogenous sources of DNA damage or stresses is critical for understanding the pathogenesis of deficiencies for FA proteins. We propose that FA proteins are centrally involved in the response to replication stress, including replication stress arising from oxidative DNA damage.

In etiopathogenesis of this type of pathology of the blood we can highlight as important: haemolytic , haemorrhagic and allergic components, but the nature and extent of the changes under there are unequal. This requires the development of a special algorithm of examination and treatment strategies of the animal in accordance with the stages of the development of the disease. Modern conditions dictate the need, along with the actions to carry out urgent medical identification as the main etiological factor and pathogenesis, and the leading pathogenetic factors that pose a threat to the danger of other pathological processes and disease states. First, we evaluate the extent of damage to the liver, kidneys, heart, spleen and blood vessels, which is possible only if the clinic has appropriate methods and equipment. It is undeniable in this regard the importance of evidence-based recommendations for dietary nutrition of the affected animal's behavior after the clinic urgent remedial measures. The article proves high importance of evaluating the effectiveness of the treatment in the clinic

    Recent advances in the treatment of aplastic anemia (AA) made most of patients to expect to achieve a long-term survival. Allogeneic stem cell transplantation (SCT) from HLA-matched sibling donor (MSD-SCT) is a preferred first-line treatment option for younger patients with severe or very severe AA, whereas immunosuppressive treatment (IST) is an alternative option for others. Horse anti-thymocyte globuline (ATG) with cyclosporin A (CsA) had been a standard IST regimen with acceptable response rate. Recently, horse ATG had been not available and replaced with rabbit ATG in most countries. Subsequently, recent comparative studies showed that the outcomes of patients who received rabbit ATG/CsA were similar or inferior compared to those who received horse ATG/CsA. Therefore, further studies to improve the outcomes of IST, including additional eltrombopag, are necessary. On the other hand, the upper age limit of patients who are able to receive MSD-SCT as first-line treatment is a current issue because of favorable outcomes of MSD-SCT of older patients using fludarabine-based conditioning. In addition, further studies to improve the outcomes of patients who receive allogeneic SCT from alternative donors are needed. In this review, current issues and the newly emerging trends that may improve their outcomes in near futures will be discussed focusing the management of patients with AA.

    Full Text Available Autoimmune hemolytic anemia (AIHA is a rare disease with an estimated prevalence of around 17/100,000. It is often difficult to diagnose and treat AIHA, especially in elderly. A 60-year-old female was admitted with the complaints of low grade fever, on-off for 6 months, progressive fatigue and dyspnea on exertion. She was transfused with three units of blood within these 6 months. Examination revealed pallor, edema, hemic murmur, and palpable liver. Hb was 2.9 gm%, T Bil 5.2 mg/dl, ESR 160 mm, and reticulocyte count 44.05%. Direct Coombs test was positive, anti-nuclear antibody (ANA and Anti ds DNA were positive. A diagnosis of systemic lupus erythematosus (SLE with AIHA was considered and patient was transfused with two units of packed red cells and put on steroid (prednisolone at 1 mg/kg body weight daily. After 3 weeks, her Hb had increased to 10.4 gm% with gross clinical improvement.

    The major causes of iron deficiency anemia (IDA) include iron loss due to bleeding, increased iron requirements, and decreased iron absorption by the intestine. The most common cause of IDA in Japanese women is iron loss during menstruation. Autoimmune atrophic gastritis and Helicobacter pylori infection can also cause IDA by reducing intestinal iron absorption. In addition to these common etiologies, germline mutations of TMPRSS6 can cause iron-refractory IDA (IRIDA). TMPRSS6 encodes matriptase-2, a membrane-bound serine protease primarily expressed in the liver. Functional loss of matriptase-2 due to homozygous mutations results in an increase in the expression of hepcidin, which is the key regulator of systemic iron homeostasis. The serum hepcidin increase in turn leads to a decrease in iron supply from the intestine and macrophages to erythropoietic cells. IRIDA is microcytic and hypochromic, but decreased serum ferritin is not observed as in IDA. IRIDA is refractory to oral iron supplementation, but does respond to intravenous iron supplementation to some extent. Because genetic testing is required for the diagnoses of IRIDA, a considerable number of cases may go undiagnosed and may thus be overlooked.

    Full Text Available This study evaluated the association between anemia and physical functional capacity in a cross-sectional population-based sample of 709 hospitalized elderly patients aged 60 years and over admitted to the Madre Teresa Hospital, Belo Horizonte, State of Minas Gerais, Brazil. The Mann-Whitney or "t" test, and chi-square or Fisher exact test were used for quantitative and categorical variables, respectively, and hierarchical binary logistic regression was used to identify significant predictors. The presence of anemia was found in 30% of participants and was significantly associated with decreased functionality according to the two measures which were used - ADL (activities of daily living and IADL (instrumental activities of daily living. Anemia was also independently associated with older age. The results of this study demonstrate a strong association between the presence of anemia and lower levels of functional capacity. Further investigations are needed to assess the impact of anemia treatment on the functionality and independence of older people.

    Full Text Available Abstract Background HIV-associated anemia is common and associated with poor prognosis. However, its response to antiretroviral treatment (ART in rural Africa is poorly understood. Methods HIV-infected adults (≥15 years who enrolled in HIV care at Haydom Lutheran Hospital in northern Tanzania were included in the study. The effect of ART (zidovudine/stavudine + lamivudine + efavirenz/nevirapine on HIV-associated anemia was studied in a subset of patients who were anemic at the time they started ART and had a follow-up hemoglobin measurement 12 months later. Pregnant women were excluded from the study, as were women who had given birth within the past 6 weeks. Anemia was defined as hemoglobin Results At enrollment, mean hemoglobin was 10.3 g/dL, and 649 of 838 patients (77.4% were anemic. Of the anemic patients, 254 (39.1% had microcytosis and hypochromia. Among 102 patients who were anemic at ART initiation and had a follow-up hemoglobin measurement after 12 months, the mean hemoglobin increased by 2.5 g/dL (P Conclusions Most patients had anemia at enrollment, of whom nearly 40% had microcytosis and hypochromia suggestive of iron deficiency. The mean hemoglobin increased significantly in patients who received ART, but one third were still anemic 12 months after ART initiation indicating that additional interventions to treat HIV-associated anemia in rural Africa might be warranted, particularly in patients with microcytosis and those treated with zidovudine.

    Full Text Available Anemia is major public health problem affecting 1.6 billion people worldwide. The poor compliance of iron supplementation remains main contributor for high prevalence of anemia. The current paper reviewed the effectiveness of direct observation of oral iron supplementation on anemia. A systematic search was performed through electronic databases and local libraries. Search strategies used subject headings and key words “directly observed” and “iron supplementation.” Searches were sought through April 2014. A total of 14 articles were included in the study. Findings were presented in three categories. First, all of those reported an improvement in compliance of iron supplementation. Second, reduction in the prevalence of anemia was reported by all and third, all except one reported increased blood hemoglobin level. Directly observed an iron supplementation is an effective approach for prevention and management of anemia in vulnerable groups. However, larger trials are needed before concluding that scaling up directly observed iron supplementation through community health volunteers would be beneficial.

    Despite the improvement in some indicators of maternal health, the rate of anemia in pregnancy in South Sharqiya Region, Oman was not satisfactory. The aim of this work was to study the correlates of anemia in pregnancy and its outcomes at the ANC clinics in South Sharqiya health centers. A health facility-based follow up study was designed in 1998. In randomly selected 5 health centers representing all wilayats of South Sharqiya Region, Oman, a form for monthly data collection from the ANC registers was used to follow up 852 pregnant women till their pregnancies ended. Hemoglobin estimation was done four times monthly apart for pregnant women and data was entered into the computer using EPI info program. The data of 852 pregnant females was analyzed where 43.6% of the sample were anemic. Logistic Regression showed that mother age and weight were significantly associated with anemia in pregnancy. Follow up of pregnant anemic women was not satisfactory. Anemic pregnant women showed response to iron supplement and folic acid received. No significant association between anemia in pregnancy whatever its grade and LBW or still birth. The follow-up system of anemia in pregnancy should be stricter. Good dietary history has to be taken from pregnant females for better nutritional education and to rule out unhealthy nutritional practices.

    The present work is based upon a prospective in study done in a semi-urban area of suburbs of Tunis, from february to November 1997. A total of 302 children aged between 6 month to 5 years were enrolled in the survey. The study aimed at assessing the extention of parasitoses in preschool aged children. The relationship between the Giardiasis intestinalis and ferropenic anemia. The prevalence of anemia is 31.78% (n = 302). The parasitologic analysis has shown that 113 children out of 302 are infected; 37.41%. We observed an obvious predominance of Giardia Lamblia: 62% (n = 113) pathogenic protozoon. The rate of anemia parasited children is amounted to 19.78%. During the Giardiasis, anemia is present in 23.17% of the cases. The Polyparasitism concerns 16% of the infested children. This anemia could be caused by a global bad absorption syndrome or by a ferro-elective bad absorption. A proper sanitary education, a purification action and also a curative treatment of the beaners carriers will be the only guarantees to decrease its morbidity.

    Concern about environmental lead exposure as a significant public health threat has increased as evidence has accumulated regarding adverse health effects at successively lower levels. Aplastic anemia is a hematological disorder of unknown etiology with a high lethality rate. Lead is a known toxicant for the hematopoietic system. Oxidative stress appears to be the possible mode of lead toxicity. We evaluated the effects of blood lead level on oxidative stress parameters in children suffering from aplastic anemia disease. Seventeen children with aplastic anemia disease (15 male and 2 female, age 3-12 y) were recruited in the study group. Fifty one healthy children (45 male and 6 female, age 3-12 y) having normal blood profiles and not suffering from any chronic disease(s) were used as controls. Blood lead level and oxidative stress parameters were determined. Mean blood lead level was significantly higher while δ-aminolevulinic acid dehydratase (δ-ALAD) activity, a biomarker for lead exposure was significantly lower in the study group as compared to the control group (p lead levels with δ-ALAD (r = -0.45; p lead induces oxidative stress in children suffering from aplastic anemia. Lead-induced oxidative stress as an underlying mechanism for aplastic anemia warrants further research.

    The basic purpose of this study is the delineation and exploitation of inborn anemias of the laboratory mouse, carried out by utilization of genetically homogeneous stocks segregating only for anemia-producing genes; by physiological and histological descriptions of each condition at all stages in the life history; by determination of tissue sites of primary gene action through tissue culture studies, tissue transplantation and parabiosis experiments; by analysis of reactions of normal and anemic mice to a variety of stressful stimuli, including x-irradiation, hypoxia, and toxic chemicals, and by biochemical comparisons between tissues, especially erythrocytes and hemopoietic cells of normal vs each type of anemic mouse. At present 16 single-locus anemias are known in the mouse, plus one with multifactorial inheritance (the autoimmune hemolytic anemia of NZB inbred mice). Of these, six are maintained only by the Jackson Laboratory, and two others have but one additional source. Effects of anemia-producing mutant alleles of these loci (an; f; ja; ha; Hba/sup th/; mk; nb; Sl and Sl/sup d/; sla; sph; and W, W/sup v/, W/sup J/ and 10 other putative W-alleles) are currently under investigation at the Jackson Laboratory. 15 refs.

    2014-01-01

    Iron deficiency anemia (IDA) continues to be major public health problem in India. It is estimated that about 20% of maternal deaths are directly related to anemia and another 50% of maternal deaths are associated with it. The question, therefore, is why, despite being the first country to launch the National Nutritional Anemia Prophylaxis Programme in 1970, the problem of IDA remains so widespread. As is to be expected, the economic implications of IDA are also massive. The issues of control of IDA in India are multiple. Inadequate dietary intake of iron, defective iron absorption, increased iron requirements due to repeated pregnancies and lactation, poor iron reserves at birth, timing of umbilical cord clamping, timing and type of complementary food introduction, frequency of infections in children, and excessive physiological blood loss during adolescence and pregnancy are some of the causes responsible for the high prevalence of anemia in India. In addition, there are other multiple programmatic and organizational issues. This review, therefore, is an attempt to examine the current burden of anemia in India, its epidemiology, and the various issues regarding its prevention and control, as well as to offer some innovative approaches to deal with this major health problem.

    Autoimmune hemolytic anemia associated with an ovarian teratoma is a very rare disease. However, treating teratoma is the only method to cure the hemolytic anemia, so it is necessary to include ovarian teratoma in the differential diagnosis of autoimmune hemolytic anemia. We report herein on a case of a young adult patient who had severe autoimmune hemolytic anemia that was induced by an ovarian teratoma. A 25-yr-old woman complained of general weakness and dizziness for 1 week. The hemoglobi...

  6. Clonal hematopoiesis in acquired aplastic anemia

    Science.gov (United States)

    2016-01-01

    Clonal hematopoiesis (CH) in aplastic anemia (AA) has been closely linked to the evolution of late clonal disorders, including paroxysmal nocturnal hemoglobinuria and myelodysplastic syndromes (MDS)/acute myeloid leukemia (AML), which are common complications after successful immunosuppressive therapy (IST). With the advent of high-throughput sequencing of recent years, the molecular aspect of CH in AA has been clarified by comprehensive detection of somatic mutations that drive clonal evolution. Genetic abnormalities are found in ∼50% of patients with AA and, except for PIGA mutations and copy-neutral loss-of-heterozygosity, or uniparental disomy (UPD) in 6p (6pUPD), are most frequently represented by mutations involving genes commonly mutated in myeloid malignancies, including DNMT3A, ASXL1, and BCOR/BCORL1. Mutations exhibit distinct chronological profiles and clinical impacts. BCOR/BCORL1 and PIGA mutations tend to disappear or show stable clone size and predict a better response to IST and a significantly better clinical outcome compared with mutations in DNMT3A, ASXL1, and other genes, which are likely to increase their clone size, are associated with a faster progression to MDS/AML, and predict an unfavorable survival. High frequency of 6pUPD and overrepresentation of PIGA and BCOR/BCORL1 mutations are unique to AA, suggesting the role of autoimmunity in clonal selection. By contrast, DNMT3A and ASXL1 mutations, also commonly seen in CH in the general population, indicate a close link to CH in the aged bone marrow, in terms of the mechanism for selection. Detection and close monitoring of somatic mutations/evolution may help with prediction and diagnosis of clonal evolution of MDS/AML and better management of patients with AA. PMID:27121470

    2014-01-01

    Full Text Available Autoimmune hemolytic anemia (AIHA is not an uncommon clinical disorder and requires advanced, efficient immunohematological and transfusion support. Many AIHA patients have underlying disorder and therefore, it is incumbent upon the clinician to investigate these patients in detail, as the underlying condition can be of a serious nature such as lymphoproliferative disorder or connective tissue disorder. Despite advances in transfusion medicine, simple immunohematological test such as direct antiglobulin test (DAT still remains the diagnostic hallmark of AIHA. The sensitive gel technology has enabled the immunohematologist not only to diagnose serologically such patients, but also to characterize red cell bound autoantibodies with regard to their class, subclass and titer in a rapid and simplified way. Detailed characterization of autoantibodies is important, as there is a relationship between in vivo hemolysis and strength of DAT; red cell bound multiple immunoglobulins, immunoglobulin G subclass and titer. Transfusing AIHA patient is a challenge to the immunohematologist as it is encountered with difficulties in ABO grouping and cross matching requiring specialized serological tests such as alloadsorption or autoadsorption. At times, it may be almost impossible to find a fully matched unit to transfuse these patients. However, transfusion should not be withheld in a critically ill patient even in the absence of compatible blood. The "best match" or "least incompatible units" can be transfused to such patients under close supervision without any serious side-effects. All blood banks should have the facilities to perform the necessary investigations required to issue "best match" packed red blood cells in AIHA. Specialized techniques such as elution and adsorption, which at times are helpful in enhancing blood safety in AIHA should be established in all transfusion services.

    without anemia,the mortality risk increased by 25% in the subjects with anemia after adjusting confounding factors(HR=1.25, 95%CI:1.03-1.52). Macrocytic anemia,simplex microcytic anemia and microcytic hypochromic anemia were all associated with the increased mortality in the oldest old people. Compared with the subjects with low hemoglobin concentration,the subjects with high hemoglobin concentration had a lower mortality risk,and the association was more obvious in women. Conclusion Anemia and low hemoglobin concentration were associated with higher mortality risk in the oldest old people in China, indicating the importance of anemia prevention and treatment among this population.

    Iron overload in transfusion-dependent patients with rare anemias can be managed with chelation therapy. This study evaluated deferasirox efficacy and safety in patients with myelodysplastic syndromes (MDS), aplastic anemia (AA) or other rare anemias. A 1-year, open-label, multicenter, single-arm, phase II trial was performed with deferasirox (10–40 mg/kg/day, based on transfusion frequency and therapeutic goals), including an optional 1-year extension. The primary end point was a change in liver iron concentration (LIC) after 1 year. Secondary end points included changes in efficacy and safety parameters (including ophthalmologic assessments) overall as well as in a Japanese subpopulation. Overall, 102 patients (42 with MDS, 29 with AA and 31 with other rare anemias) were enrolled; 57 continued into the extension. Mean absolute change in LIC was –10.9 mg Fe/g dry weight (d.w.) after 1 year (baseline: 24.5 mg Fe/g d.w.) and –13.5 mg Fe/g d.w. after 2 years. The most common drug-related adverse event was increased serum creatinine (23.5%), predominantly in MDS patients. Four patients had suspected drug-related ophthalmologic abnormalities. Outcomes in Japanese patients were generally consistent with the overall population. Results confirm deferasirox efficacy in patients with rare anemias, including a Japanese subpopulation. The safety profile was consistent with previous studies and ophthalmologic parameters generally agreed with baseline values (EUDRACT 2006-003337-32).

    A gastric intrinsic factor output under 200 U/h after pentagastrin stimulation (N > 2000 U/h) is specific for pernicious anemia. The other findings are either variable or non specific. Serum intrinsic factor antibodies, considered as specific in general practice, are present only in half of the patients with pernicious anemia. In their absence, since the disappearance of the Schilling tests, the gastric tubage currently used for the study of gastric acid secretion, is obligatory for the simultaneous study of intrinsic factor output. This study is important to eliminate another disease much more frequent than pernicious anemia, the protein bound to cobalamin malabsorption was observed in achlorhydric simple atrophic gastritis in the presence of intrinsic factor secretion.

    2000-01-01

    Full Text Available Hemolysis is observed in more than 50% of patients with cirrhosis. However, there has been little documention of the association of primary biliary cirrhosis with autoimmune hemolytic anemia. Two cases, found within a single practice, of primary biliary cirrhosis coexisting with autoimmune hemolysis and a third case coexisting with hereditary spherocytosis are presented. Anemia in such patients is commonly attributed to chronic disease, and hyperbilirubinemia is attributed to primary biliary cirrhosis. These patients were considered for liver transplantation until the diagnosis of a comorbid hemolytic process was established. This association may be more prevalent than previously recognized. A diagnosis of comorbid hemolysis must always be considered in context with anemia and serum bilirubin levels that rise out of proportion to the severity of the primary biliary cirrhosis.

    Full Text Available Anemia in neonatal period is rare, with the common causes being Rh and ABO blood group incompatibility, hemorrhagic disease of newborn, congenital hemolytic anemia, hemoglobinopathies, and TORCH (toxoplasmosis, rubella, cytomegalovirus, herpes virus infections. Congenital leukemia and infantile osteopetrosis (OP are among the rare causes of neonatal anemia. A review of the literature shows approximately 200 reported cases of congenital leukemia. Articles describing the imaging features of congenital leukemia are still rarer. Infantile OP, another rare disorder with a reported incidence of 1 in 250,000 has characteristic imaging features, which are diagnostic of the disease. We report a case each, of two rare diseases: Congenital leukemia and infantile osteopetrosis. Additionally, our report highlights the radiological and imaging features of congenital leukemia and infantile OP and their crucial role in arriving at an early diagnosis.

    The purpose of this study was to compare the findings of magnetic resonance (MR) spectroscopy of hyperplastic hematopoietic marrow with those of normal bone marrow. Twenty-four samples of normal marrow from eight control subjects and 19 samples of hyperplastic marrow in aplastic anemia were examined with a 1.5 T MR unit. The former showed low intensity on opposed-phase T1-weighted images, while the latter showed high intensity on both fast STIR and opposed-phase T1-weighted images. MR spectroscopy quantitatively confirmed that the water; fat ratio was increased and the transverse relaxation time of water was changed in hyperplastic bone marrow, compared with normal bone marrow. In summary, MR imaging is able to detect hematopoietic regions among a wide range of bone marrow of aplastic anemia, while MR spectroscopy allowed us to quantitatively analyze the cell population of hyperplastic hematopoietic marrow in aplastic anemia.

With a diagnosis of autoimmune hemolytic anemia (AIHA, prednisolone was started but was ineffective after 1 month of therapy. A bone marrow trephine biopsy revealed pure red cell aplasia (PRCA showing severe erythroid hypoplasia. The case was considered PRCA following AIHA. This combination without clear underlying disease is rare. Human parvovirus B19 infection was not detected in the marrow aspirate during reticulocytopenia. The patient received azathioprine, and PRCA improved but significant hemolysis was once again documented with a high reticulocyte count. The short time interval between AIHA and PRCA phase suggested an increased possibility of the evolution of a single disease.

    Hemolysis is a common feature in patients with β-thalassemia major. As a result, autoimmune hemolytic anemia complicating β-thalassemia is easily overlooked. Here, the authors described the clinical features and management of 7 patients with β-thalassemia major and autoimmune hemolytic anemia. These patients had fever, cough, and tea-colored urine on admission. The laboratory investigations showed a significant drop in hemoglobin and increased serum bilirubin. Coombs' tests revealed that anti-immunoglobulin G (IgG) and anti-C3 was positive in 7 and 5 cases, respectively, whereas anti-Rh E alloantibody was positive in 3 cases. All the patients received corticosteroids treatments and blood transfusions. Patients with anti-Rh E alloantibodies also received immunoglobulin treatments. Six of the patients responded well to the management, but 1 patient developed recurrent autoimmune hemolytic anemia that required cyclosporin A treatment. All the patients remained well by following up for more than 6 months.

    2015-03-10

    Iron deficiency and iron deficiency anemia are global health problems leading to deterioration in patients' quality of life and more serious prognosis in patients with chronic diseases. The cause of iron deficiency and anemia is usually a combination of increased loss and decreased intestinal absorption and delivery from iron stores due to inflammation. Oral iron is first line treatment, but often hampered by intolerance. Intravenous iron is safe, and the preferred treatment in patients with chronic inflammation and bowel diseases. The goal of treatment is normalisation of hemoglobin concentration and recovery of iron stores. It is important to follow up treatment to ensure that these objectives are met and also long-term in patients with chronic iron loss and/or inflammation to avoid recurrence of anemia.

    Full Text Available Neil D Goldberg Emeritus Chief of Gastroenterology, University of Maryland St. Joseph Medical Center, Towson, MD, USA Abstract: Iron deficiency anemia is the most common form of anemia worldwide, caused by poor iron intake, chronic blood loss, or impaired absorption. Patients with inflammatory bowel disease (IBD are increasingly likely to have iron deficiency anemia, with an estimated prevalence of 36%–76%. Detection of iron deficiency is problematic as outward signs and symptoms are not always present. Iron deficiency can have a significant impact on a patient's quality of life, necessitating prompt management and treatment. Effective treatment includes identifying and treating the underlying cause and initiating iron replacement therapy with either oral or intravenous iron. Numerous formulations for oral iron are available, with ferrous fumarate, sulfate, and gluconate being the most commonly prescribed. Available intravenous formulations include iron dextran, iron sucrose, ferric gluconate, and ferumoxytol. Low-molecular weight iron dextran and iron sucrose have been shown to be safe, efficacious, and effective in a host of gastrointestinal disorders. Ferumoxytol is the newest US Food and Drug Administration-approved intravenous iron therapy, indicated for iron deficiency anemia in adults with chronic kidney disease. Ferumoxytol is also being investigated in Phase 3 studies for the treatment of iron deficiency anemia in patients without chronic kidney disease, including subgroups with IBD. A review of the efficacy and safety of iron replacement in IBD, therapeutic considerations, and recommendations for the practicing gastroenterologist are presented.

    Full Text Available Background: Anemia chronic disease (ACD is an anemia found in certain chronic disease states, typically marked by the disturbance of iron homeostasis or hypoferremia. This condition leads to shortage of iron for hemoglobin synthesis but the iron storage in bone marrow is left undisturbed. The discovery of hepcidin and its role in iron metabolism has given new insights in anemia chronic disease management. Consecutive sampling method was applied to choose ACD patients at Sanglah General Hospital, Bali-Indonesia. Questionnaire was constructed to note demographic aspect and disease or clinical condition underlies ACD (inflammation, infection, malignancy and others. Hepcidin, Serum IL-6 and CRP level were measured. Sample size and Path analysis mediation method were used to define hepcidin’s role on mechanism how anemia develop in ACD patients in which the direct and indirect effects of IL-6 and CRP to hemoglobin (Hb  were counted partially or combined through hepcidin mediation variable. The cumulative influence of IL-6, CRP and hepcidin on anemia (Hb was only 0.12 or about 12% of hemoglobin level was influenced by IL-6, CRP and hepcidin together whereas the other 93% was influenced by another unknown and unclear factors. Hepcidin could be used as a mediation variable for the development of anemia because the direct influence of IL-6 as exogenous factor was less than its indirect influence through hepcidin. It was not proven for CRP as exogenous variable because the direct influence of CRP to hemoglobin was stronger than the influence of CRP through hepcidin.

Patients and Methods: Anticoagulated blood and sera samples were obtained from 480 women consisting of 292 pregnant and 188 non-pregnant women. Antibodies to HIV were detected in the sera samples and hemoglobin concentration of the anticoagulated blood specimens were determined using standard techniques. Anemia was defined as hemoglobin concentration <11g/dl for pregnant women and <12g/dl for non-pregnant women. Results: Pregnancy was not a risk factor for acquiring HIV infection (pregnant vs. non-pregnant: 10.2% vs. 13.8%; OR=0.713, 95% CI=0.407, 1.259, P = 0.247. The prevalence of HIV was significantly (P = 0.005 and P = 0.025 higher in the age group 10-20 years and 21 - 30 years among pregnant and non-pregnant women respectively. Pregnancy was a risk factor for acquiring anemia (OR=1.717, 95% CI=1.179, 2.500, P = 0.006. Only the age of pregnant women significantly (P = 0.004 affected the prevalence of anemia inversely. Conclusion: The prevalence of HIV and anemia among pregnant women were 10.2% and 49.3% respectively. Pregnancy was associated with anemia. Interventions by appropriate agencies are advocated to reduce associated sequelae.

  12. Glycine and Folate Ameliorate Models of Congenital Sideroblastic Anemia.

    Full Text Available Sideroblastic anemias are acquired or inherited anemias that result in a decreased ability to synthesize hemoglobin in red blood cells and result in the presence of iron deposits in the mitochondria of red blood cell precursors. A common subtype of congenital sideroblastic anemia is due to autosomal recessive mutations in the SLC25A38 gene. The current treatment for SLC25A38 congenital sideroblastic anemia is chronic blood transfusion coupled with iron chelation. The function of SLC25A38 is not known. Here we report that the SLC25A38 protein, and its yeast homolog Hem25, are mitochondrial glycine transporters required for the initiation of heme synthesis. To do so, we took advantage of the fact that mitochondrial glycine has several roles beyond the synthesis of heme, including the synthesis of folate derivatives through the glycine cleavage system. The data were consistent with Hem25 not being the sole mitochondrial glycine importer, and we identify a second SLC25 family member Ymc1, as a potential secondary mitochondrial glycine importer. Based on these findings, we observed that high levels of exogenous glycine, or 5-aminolevulinic acid (5-Ala a metabolite downstream of Hem25 in heme biosynthetic pathway, were able to restore heme levels to normal in yeast cells lacking Hem25 function. While neither glycine nor 5-Ala could ameliorate SLC25A38 congenital sideroblastic anemia in a zebrafish model, we determined that the addition of folate with glycine was able to restore hemoglobin levels. This difference is likely due to the fact that yeast can synthesize folate, whereas in zebrafish folate is an essential vitamin that must be obtained exogenously. Given the tolerability of glycine and folate in humans, this study points to a potential novel treatment for SLC25A38 congenital sideroblastic anemia.

    Full Text Available Hereditary hemolytic anemia encompasses a heterogeneous group of anemias characterised by decreased red blood cell survival because of inherited membrane, enzyme, or hemoglobin disorders. Affected red blood cells are more fragile, less deformable, and more susceptible to shear stress and oxidative damage, and show increased vesiculation. Red blood cells, as essentially all cells, constitutively release phospholipid extracellular vesicles in vivo and in vitro in a process known as vesiculation. These extracellular vesicles comprise a heterogeneous group of vesicles of different sizes and intracellular origins. They are described in literature as exosomes if they originate from multi-vesicular bodies, or as microvesicles when formed by a one-step budding process directly from the plasma membrane. Extracellular vesicles contain a multitude of bioactive molecules that are implicated in intercellular communication and in different biological and pathophysiological processes. Mature red blood cells release in principle only microvesicles. In hereditary hemolytic anemias, the underlying molecular defect affects and determines red blood cell vesiculation, resulting in shedding microvesicles of different compositions and concentrations. Despite extensive research into red blood cell biochemistry and physiology, little is known about red cell deformability and vesiculation in hereditary hemolytic anemias, and the associated pathophysiological role is incompletely asessed. In this review, we discuss recent progress in understanding extracellular vesicles biology, with focus on red blood cell vesiculation. Also, we review recent scientific findings on the molecular defects of hereditary hemolytic anemias, and their correlation with red blood cell deformability and vesiculation. Integrating bio-analytical findings on abnormalities of red blood cells and their microvesicles will be critical for a better understanding of the pathophysiology of hereditary

    Autoimmune hemolytic anemia with giant cell hepatitis is a distinct entity in children. It is usually fatal with progressive liver disease. Immunosuppressive treatment with conventional drugs offers some response; however, it is usually only temporary. Alternative therapeutic options with monoclonals have been reported with promising remission of the disease. We report a case with autoimmune hemolytic anemia+giant cell hepatitis after varicella infection. She was resistant to standard immunosuppressive combinations, and rescue therapy with rituximab was used. Remission was not achieved with the drug and the child died with septic complication.

    Full Text Available A anemia falciforme tem um desenvolvimento clínico extremamente variável que se caracteriza principalmente por diferentes graus de intensidade da anemia hemolítica. As razões dessa variabilidade são parcialmente conhecidas na expressão fenotípica da doença. Apesar de ter um mesmo defeito genético, a anemia falciforme pode estar associada com níveis diferentes de Hb Fetal e interações com talassemia alfa que atuam como modeladores genéticos da doença. Entretanto, outros defeitos genéticos dos eritrócitos, com destaques para a deficiência de G-6PD, a esferocitose e as deficiências de enzimas anti-oxidantes (SOD, GPx e catalase certamente interferem no curso clínico da doença. Os diferentes haplótipos da Hb S denominados por Banto, Benin, Senegal, Camarões e Asiático, tem sido apontados também como possíveis causas da heterogeneidade fenotípica da anemia falciforme. Toda essa diversidade que caracteriza a anemia falciforme está, em parte, relacionada à sua origem multicêntrica e que envolvem populações com diferentes anormalidades genéticas de proteínas e enzimas eritrocitárias. Por outro lado, além desses fatores caracterizados como interferentes eritrocitários, há os interferentes do meio ambiente em que está inserido o doente com anemia falciforme. Entre os interferentes ambientais destacam-se as situações sociais, econômicas e culturais do doente, e que tem influência no curso de sua doença. Diante desse quadro complexo e interativo, o presente artigo mostra a influência de certos interferentes eritrocitários e ambientais na anemia falciforme. Ao finalizar o artigo é proposto um protocolo de monitoramento laboratorial das síndromes falcêmicas, com destaque para a anemia falciforme.

    Hemolytic anemia (HA) is not an exceptional situation in adults. While establishing the hemolytic mechanism of an anemia is usually rather easy, finding the etiology may be quite difficult as both some hereditary (corpuscular) and acquired causes of HA may occur during adulthood. The diagnosis of HA therefore requires a multiple step procedure taking into account both patient's and family history, a careful analysis of the blood smear and a direct antiglobulin test. Based on these first data, the diagnosis procedure may then require more specific tests whose indications are discussed in this review.

    The prevalence of celiac disease (CD) appears to be increasing in the United States. However, the proportion of new CD cases with atypical presentations is also rising. We present the case of a 49-year-old woman who was diagnosed with CD in the setting of new, severe iron-deficiency anemia, 13 years into treatment of diarrhea-predominant irritable bowel syndrome associated with chronic mildly elevated liver function tests. While CD and iron deficiency anemia are common, this is a rare presentation of CD. PMID:27406450

    A 61-year-old eutrophic male was diagnosed with vitamin B12 deficiency and megaloblastic anemia. A modified Schilling test suggested intestinal malabsorption unrelated to intrinsic factor deficiency. Subsequent colonoscopy revealed the presence of a Taenia tapeworm. The anemia resolved within days under therapy with niclosamide and temporary vitamin B12 supplements. The present case suggests that, in addition to other well-known parasitic agents, e.g., Diphyllobothrium latum and Giardia lamblia, Taenia infestation can also be a cause of intestinal vitamin B12 malabsorption.

    Full Text Available Anemia is common in critically ill patients. As a consequence packed red blood cell (PRBC transfusions are frequent in the critically ill. Over the past two decades a growing body of literature has emerged, linking PRBC transfusion to infections, immunosuppression, organ dysfunction, and a higher mortality rate. However, despite growing evidence that risk of PRBC transfusion outweighs its benefit, significant numbers of critically ill patients still receive PRBC transfusion during their intensive care unit (ICU stay. In this paper, we summarize the current literature concerning the impact of anemia on outcomes in critically ill patients and the potential complications of PRBC transfusions.

    A 24-year-old male patient with a severe aplastic anemia (SAA) was treated with equine-antilymphocyte globulin (ALG). As complication of this treatment he developed a severe heteroimmune hemolytic anemia mediated by anti-species pan-agglutinin antibodies present in ALG. In spite of the fact that ALG is absorbed with red-cell stroma and platelets to remove anti-erythrocyte and anti-platelet contaminating antibodies, often only partial absorption is achieved, and the remaining antibodies are passively acquired by the recipient. Neutropenia and especially thrombocytopenia are usual complications of this treatment, but it is also possible to detect anti-erythrocyte antibodies in the serum and on the red cells of those patients. However, the unusual severity of the hemolysis suffered by our patient, with a striking decrease of the hemoglobin levels (Fig. 1) can be ascribed to the administration of ALG at a time at which the hematocrit was close to normal as a result of the previous administration of anabolics. It is likely that in severely anemic patients, with a high transfusional demand, such a hemolytic episode may remain undetected. The patient acquired reactivity to the direct antiglobulin test, as well as the positive results of investigation of unexpected antibodies and compatibility testing can be accounted for by the fact that commercial antihuman globulin serum (AGS) contains antibodies reacting with a globulin component shared by human and horse sera. Neutralization of AGS with ALG administered to the patient removed those cross-reacting antibodies, making it possible to perform reliable transfusion compatibility testing and to rule out the eventual presence of hidden alloantibodies or warm autoantibodies. Neutralized Coombs serum maintained its human antiglobulin properties unaltered (Table 1).(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Pernicious anemia is an autoimmune disease with a variety of clinical presentations. We describe a case of pernicious anemia presenting with pancytopenia with hemolytic features. Further workup revealed very low vitamin B12 levels and elevated methylmalonic acid. It is important for a general internist to identify pernicious anemia as one of the cause of pancytopenia and hemolytic anemia to avoid extensive workup. Pernicious anemia can present strictly with hematological abnormalities without neurological problems or vice versa as in our case.

Na tentativa de tornar esse diagnóstico menos oneroso e mais eficiente, o uso de parâmetros dos contadores automáticos tem sido sugerido. O objetivo deste estudo foi avaliar a eficiência diagnóstica de alguns parâmetros do hemograma na diferenciação das anemias microcíticas. Foram comparados os parâmetros hematológicos de 395 pacientes portadores de anemia ferropriva, anemia de doença crônica ou talassemia menor. O número de hemácias apresentou os maiores valores combinados de sensibilidade e especificidade na diferenciação dessas anemias. Em conclusão, a contagem de hemácias pode ser útil no diagnóstico diferencial de anemias microcíticas.Differential diagnosis of microcytic anemia is clinically important. In an attempt to make this diagnosis more cost-effective, the use of some parameters obtained from automated blood count analyzers has been suggested. The objective of this study was to evaluate the efficiency of blood count parameters in differentiating microcytic anemias. Blood parameters were compared in 395 patients with iron deficiency anemia, chronic disease anemia or thalassemia minor. The number of red blood cells showed the highest combined sensitivity and specificity in differentiating these anemias. Hence, blood counts may be a useful tool in the differential diagnosis of microcytic anemias.

    Full Text Available Introduction: The association of anemia with primary hypothyroidism has been common knowledge for many years. However; its pathogenesis is far from clear in many cases. Often the causes of anemia are manifold. Aims and objectives: In this study, we evaluated the causes of anemia in patients with primary hypothyroidism. Materials and Methods : Sixty adult nonpregnant untreated primary hypothyroid patients with anemia without any obvious cause were included. All patients were subjected to full medical history, clinical examination, biochemical and imaging studies. Serum iron profile, vitamin B12, folic acid, anti parietal cell antibody, anti TPO antibody, bone marrow study, and stool for occult blood, Coomb′s test, HPLC for hemoglobinopathies and complete hemogram with reticulocyte count were done and analyzed. Results: Normocytic, normochromic anemia was present in 31 patients (51.6% followed by microcytic anemia in 26 patients (43.3%. Six patients (10% had megaloblastic anemia with vitamin B12 deficiency including 3 cases of pernicious anemia. Two patients had combined deficiency of iron and vitamin B12. Conclusion: Normocytic normochromic anemia with normal bone marrow was commonest type of anemia in this study, followed by iron deficiency anemia.

    Anemia is a global public health problem affecting both developing and developed countries at all ages. According to the World Health Organization (WHO), anemia is defined as hemoglobin (Hb) levels Anemia is often multifactorial and is not an independent phenomenon. For the classification and diagnosis the hematologic parameters, the underlying pathological mechanism and patient history should be taken into account. The aging of population, especially in Western countries, causes an increase of anemia in elderly people. In this population, anemia, recently defined by levels of Hb anemia in this population is important because it contributes to morbidity and mortality. In one third of the patients, anemia is due to nutritional deficiency, including iron, folate, or vitamin B12 deficiency; moreover, anemia of chronic disease accounts for about another third of the cases. However, in one third of patients anemia cannot be explained by an underlying disease or by a specific pathological process, and for this reason it is defined "unexplained anemia". Unexplained anemia might be due to the progressive resistance of bone marrow erythroid progenitors to erythropoietin, and a chronic subclinical pro-inflammatory state.

    The cardiac status of 64 children (ages 0.2 to 18 yr) with sickle cell anemia documented by hemoglobin electrophoresis was evaluated by echocardiography. Left atrial, left ventricular and aortic root dimensions were significantly increased in over 60 percent of these children at all ages compared to values for 99 normal black (non-SCA) control subjects. Left ventricular wall thickness was increased in only 20 percent of older children with sickle cell anemia. Estimated LV mass/m2 and left ventricular cardiac index were increased compared to control subjects (p less than 0.001). Left heart abnormalities expressed as a single composite function, derived from multivariate regression analysis, correlated well with severity of anemia expressed as grams of hemoglobin (r = -0.52, p = less than 0.001) and with percentage of hemoglobin S (r = 0.51, p less than 0.001), but not to the same extent with age. Echocardiographically assessed left ventricular function at rest was comparable to that of control subjects. These data suggest that the major cardiac abnormalities in children are related to the volume overload effects of chronic anemia, and that in this age group, there is no evidence for a distinct "sickle cell cardiomyopathy" or cardiac dysfunction.

    Full Text Available Sickle cell anemia (SCA is a chronic haemoglobinopathy that can affect many organs in the body including gastrointestinal tract. However, colonic involvement is very rare and usually in the form of ischemic colitis. We are reporting an 11-year-old Saudi girl with SCA who presented with persistent diarrhea and was found to have inflammaftory bowel disease.

    Full Text Available Background: To report a case of severe vitamin B12 deficiency anemia presenting with white centered retinal hemorrhages. Methods: Interventional case report. Results: A 40-year-old man, general practitioner himself, presented with a 1-day history of diminished left visual acuity and a drop-shaped central scotoma. The corrected visual acuities were 20/20, OD and 20/100, OS. Ophthalmic examination revealed bilaterally pale tarsal conjunctiva, discretely icteric bulbar conjunctiva and disseminated white centered intraretinal hemorrhages with foveal involvement. OCT imaging through these lesions revealed a retinal thickening caused by a sub-ILM accumulation of hyperreflective and inhomogeneous deposits within the nerve fiber layer. Immediate laboratory work-up showed severe megaloblastic anemia caused by vitamin B12 deficiency requiring erythrocyte transfusions. Discussion: Most reports of white centered retinal hemorrhages have been described in patients with leukemic retinopathy and bacterial endocarditis. It is interesting that this case of vitamin B12 deficiency anemia retinopathy has a clinically indistinguishable fundus appearance. This is probably due to the common pathology of capillary disruption and subsequent hemostatic fibrin plug formation. In megaloblastic anemia, direct anoxia results in endothelial dysfunction. The loss of impermeability allows extrusion of whole blood and subsequent diffusion from the disrupted site throughout and above the nerve fiber layer. Therefore the biomicroscopic pattern of white centered hemorrhages observed in anemic retinopathy is most likely due to the clot formation as the reparative sequence after capillary rupture.

    The unique sensitivity of early red cell progenitors to iron deprivation, known as the erythroid iron restriction response, serves as a basis for human anemias globally. This response impairs erythropoietin-driven erythropoiesis and underlies erythropoietic repression in iron deficiency anemia. Mechanistically, the erythroid iron restriction response results from inactivation of aconitase enzymes and can be suppressed by providing the aconitase product isocitrate. Recent studies have implicated the erythroid iron restriction response in anemia of chronic disease and inflammation (ACDI), offering new therapeutic avenues for a major clinical problem; however, inflammatory signals may also directly repress erythropoiesis in ACDI. Here, we show that suppression of the erythroid iron restriction response by isocitrate administration corrected anemia and erythropoietic defects in rats with ACDI. In vitro studies demonstrated that erythroid repression by inflammatory signaling is potently modulated by the erythroid iron restriction response in a kinase-dependent pathway involving induction of the erythroid-inhibitory transcription factor PU.1. These results reveal the integration of iron and inflammatory inputs in a therapeutically tractable erythropoietic regulatory circuit.
