    2015-01-01

    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 BACKGROUND: Elevated neutrophil myeloperoxidase may have a role in the diagnosis of megaloblastic erythropoiesis. AIMS: To study the differentiating role of myeloperoxidase index in megaloblastic and aplastic anemia. SETTINGS AND DESIGN: The myeloperoxidase index (MPXI was studied in 96 patients with megaloblastic and aplastic anemia diagnosed on bone marrow aspiration and biopsy examinations. METHODS AND MATERIALS: MPXI was measured with Technicon H1 (Bayer automated analyzer. Nonparametric Mann-Whitney statistical test was used to compare the MPXI values between groups. RESULTS: The mean MPXI in megaloblastics and aplastic anemia was 18.3 and 1.8 (p<0.001 respectively. MPXI >20 denoted megaloblastic and MPXI <-11.6 denoted aplastic anemia. CONCLUSION: MPXI measurement may assist differentiation of megaloblastic from aplastic anemia, while MPXI >20 rules out aplastic and MPXI <-11.6 rules out megaloblastic anemia.

    Aplastic anemia is a rare life-threatening bone marrow failure that is characterized by bicytopenia or pancytopenia in the peripheral blood and a hypoplastic or aplastic bone marrow. The patients are at risk of infection and hemorrhage due to neutropenia and thrombocytopenia and suffer from symptoms of anemia. The main treatment approaches are allogeneic stem cell transplantation and immunosuppression. Here, we review current standard immunosuppression and the attempts that have been made in the past two decades to improve results: review of recent developments also reveals that sometimes not only the advent of new drugs, good ideas and well-designed clinical trials decide the progress in the field but also marketing considerations of pharmaceutical companies. Aplastic anemia experts unfortunately had to face the situation that efficient drugs were withdrawn simply for marketing considerations. We will discuss the current options and challenges in first-line treatment and management of relapsing and refractory patients with an emphasis on adult patients. Some promising new approaches are currently under investigation in prospective, randomized trials. PMID:25572607

  15. Epidemiologic and HLA Antigen Profile in Patients with Aplastic Anemia

    International Nuclear Information System (INIS)

    Objective: To analyze patients suffering from aplastic anemia (AA, peripheral pancytopenia and hypocellular bone marrow in the absence of dysplasia, infiltration and fibrosis) for documenting patient's baseline characteristics and association with various human leucocyte antigens. Study Design: An observational, cross-sectional study. Place and Duration of Study: The National Institute of Blood Disease (NIBD), Karachi, from March 2003 to August 2008. Methodology: All consecutive patients with confirmed diagnosis of AA were evaluated. Data included the baseline characteristics, complete blood counts (CBC), bone marrow biopsy findings, severity of disease, exposure to drugs or chemicals, viral serology and their HLA expression. The data was analyzed on SPSS programme and frequencies were documented. Results: Among 318 patients, there were 236 (74.21%) males and 82 (25.78%) females. Median age was 16 and 70% belonged to urban population. Drug exposure could be established in 23 (7.23%) of cases, while 4 (1.25%) were HBV surface antigen positive and 7 (2.2%) were HCV antibodies positive. In all, 73 (22.9%) had very severe AA, 195 (61.32%) had severe AA while 50 (15.7%) cases had non-severe AA. HLA B5 (52) showed high expression in 83 patients (26%) in comparison to 5.9% reported in healthy population. Conclusion: AA was found to affect young adult males living in urban areas. HLA B5 (52) showed higher expression in patients with aplastic anemia. (author)

    Full Text Available Hepatitis-associated aplastic anemia occurs in up to 10% of all aplastic anemia cases. Syngeneic bone marrow transplantation is rare in patients with severe aplastic anemia and usually requires pre-transplant conditioning to provide engraftment. We report on a 29-year-old male patient with hepatitis-associated severe aplastic anemia who had a series of severe infectious conditions before transplantation, including tracheal inflammation. Life-threatening bleeding, which developed after bronchoscopy, was successfully treated with activated recombinant factor VII and platelet transfusions. Syngeneic peripheral blood stem cell transplantation using immunosuppressive treatment with antithymocyte globulin and cyclosporin A without high-dose pre-transplant conditioning was performed, followed by complete hematologic and hepatic recovery.

    Objective. To explore the relationship between human parvovirus B 19 (HPV B 19) infection and aplastic anemia (AA) and to investigate the role of HPV B19 in the occurrence of AA.``Methods. The presence of HPV B19 DNA was detected in the peripheral blood samples of 60 patients with AA (children 38 and adults 22) by nested polymerase chain reaction (PCR) assay, and 30 healthy persons were selected as control.``Results. Sixteen (26. 7 % ) of 60 AA cases were HPV B19 DNA positive, while all the samples in the control group were negative for HPV B19 ( P = 0. 000914). Among the case group, the positive rates of HPV B19DNA were 21.4% (6 /28), 30.0% (3 / 10), 20.0% (1 / 5) and 35.3 % (6 / 17) in children acute AA (AAA), children chronic AA (CAA), adults AAA and adults CAA patients respectively, which were significantly higher than that in the control group. Furthermore, there was no remarkable difference between children AA and adults AA in the 16 HPV B19 DNA positive patients; neither was there between AAA and CAA.``Conclusions. HPV B19 infection is not only correlated with the occurrence of children AAA and CAA, but also with adults AAA and CAA, and might be an important viral cause for AA in humans.

    2015-01-01

    Full Text Available Background: Thrombopoietin (TPO is the key hematopoietic growth factor regulating the production of platelets from bone marrow megakaryocytes and maintaining platelet hemostasis. This study was done to find any relationship between the levels of thrombopoietin and the severity of disease in patients with aplastic anemia. Materials and Methods: Serum samples were collected from 52 patients with a confirmed diagnosis of aplastic anemia and 45 normal healthy blood donors of both sexes over a period of 2 years, and TPO was estimated by using commercially available TPO-specific-enzyme-linked immunosorbent assay. Results: The median TPO level of 1190 pg/ml (range 625-7651 pg/ml in aplastic anemia patients was significantly higher than the median TPO level of 121.1 pg/ml (81.25-237.7 pg/ml in normal healthy blood donors (P = 0.000. No significant difference was observed in TPO levels of male and female patients (P = 0.453. The median TPO concentrations observed in very severe aplastic anemia, severe aplastic anemia, and nonsevere aplastic anemia were 2765 pg/ml (range 625-6451 pg/ml, 1190 pg/ml (range 672.1-7651 pg/ml, and 1111.5 pg/ml (range 761.1-2289.2 pg/ml, respectively. TPO in patients of very severe aplastic anemia was significantly higher than patients of nonsevere aplastic anemia (P = 0.043, with no significant relation among rest of the groups. Discussion: TPO levels in aplastic anemia patients were significantly higher than in healthy blood donors; however, in aplastic anemia patients TPO levels were significantly higher only in patients with very severe disease.

    2010-08-15

    Background: Standard treatment of glioblastoma multiforme consists of postoperative radiochemotherapy with temozolomide, followed by a 6-month chemotherapy. Serious hematologic complications are rarely reported. Case Report and Results: The authors present the case of a 61-year-old female patient with glioblastoma multiforme treated with external-beam radiation therapy and concomitant temozolomide. After completion of treatment, the patient developed symptoms of serious aplastic anemia that eventually led to death due to prolonged neutro- and thrombocytopenia followed by infectious complications. Conclusion: Lethal complications following temozolomide are, per se, extremely rare, however, a total of four other cases of aplastic anemia have been reported in the literature so far. (orig.)

  2. Aldehyde dehydrogenase 2 in aplastic anemia, Fanconi anemia and hematopoietic stem cells.

    2016-09-01

    Maintenance of the hematopoietic stem cell (HSC) compartment depends on the ability to metabolize exogenously and endogenously generated toxins, and to repair cellular damage caused by such toxins. Reactive aldehydes have been demonstrated to cause specific genotoxic injury, namely DNA interstrand cross-links. Aldehyde dehydrogenase 2 (ALDH2) is a member of a 19 isoenzyme ALDH family with different substrate specificities, subcellular localization, and patterns of expression. ALDH2 is localized in mitochondria and is essential for the metabolism of acetaldehyde, thereby placing it directly downstream of ethanol metabolism. Deficiency in ALDH2 expression and function are caused by a single nucleotide substitution and resulting amino acid change, called ALDH2*2. This genetic polymorphism affects 35-45% of East Asians (about ~560 million people), and causes the well-known Asian flushing syndrome, which results in disulfiram-like reactions after ethanol consumption. Recently, the ALDH2*2 genotype has been found to be associated with marrow failure, with both an increased risk of sporadic aplastic anemia and more rapid progression of Fanconi anemia. This review discusses the unexpected interrelationship between aldehydes, ALDH2 and hematopoietic stem cell biology, and in particular its relationship to Fanconi anemia. PMID:27650066

    Acquired aplastic anemia is an immune-mediated disease characterized by severe defects in stem cell number resulting in hypocellular marrow and peripheral blood cytopenias. Minor paroxysmal nocturnal hemoglobinuria populations and a short telomere length were identified as predictive biomarkers of immunosuppressive therapy responsiveness in aplastic anemia. We enrolled 113 aplastic anemia patients (63 boys and 50 girls) in this study to evaluate their response to immunosuppressive therapy. The paroxysmal nocturnal hemoglobinuria populations and telomere length were detected by flow cytometry. Forty-seven patients (42%) carried a minor paroxysmal nocturnal hemoglobinuria population. The median telomere length of aplastic anemia patients was -0.99 standard deviation (SD) (range -4.01-+3.01 SD). Overall, 60 patients (53%) responded to immunosuppressive therapy after six months. Multivariate logistic regression analysis identified the absence of a paroxysmal nocturnal hemoglobinuria population and a shorter telomere length as independent unfavorable predictors of immunosuppressive therapy response at six months. The cohort was stratified into a group of poor prognosis (paroxysmal nocturnal hemoglobinuria negative and shorter telomere length; 37 patients) and good prognosis (paroxysmal nocturnal hemoglobinuria positive and/or longer telomere length; 76 patients), respectively. The response rates of the poor prognosis and good prognosis groups at six months were 19% and 70%, respectively (Ptelomere length is an efficient predictor of poor immunosuppressive therapy response, which should be considered while deciding treatment options: immunosuppressive therapy or first-line hematopoietic stem cell transplantation. The trial was registered in www.umin.ac.jp with number UMIN000017972.

    International Nuclear Information System (INIS)

    We report a case of successfully treated Listeria monocytogenes (Lm) meningitis in a atomic bomb survivor receiving steroid therapy for aplastic anemia. The patient was a 62-year-old woman and the past medical history included hypothyroidism due to radioiodide therapy for Basedow disease, breast cancer, aplastic anemia, steroid-induced diabetes mellitus, and pulmonary tuberculosis. At the time of onset, she was receiving corticosteroid, anabolic steroid, an H2-blocker (famotidine), and other medication. Since she developed symptoms of meningitis when she visited our hospital for regular medical check-up for aplastic anemia, she was hospitalized and given antibiotic therapy, including ABPC, without delay. With this effective antibiotic therapy and successful management of the co-existing medical conditions, she was cured except for being a little euphoric. Lm meningitis is known to occur in aged and immunocompromised patients. Since most of the atomic bomb survivors are now aged and the prevalence of malignancy, diabetes mellitus, and other diseases which cause immunodeficiency have been rising year by year, Lm meningitis is one of the emergency neurologic conditions whose diagnosis should not be delayed in this population.

  11. Further Evaluation of Androgen Therapy In Aplastic Anemia: With Special Reference to Correlation Between Response to Androgen and EEI

    International Nuclear Information System (INIS)

    Patients with aplastic anemia were treated with a combination of depo-testosterone cyclopentylpropionate (Upjohn) and dexamethasone. In 7 of 15 patients treated, there was response in which either a significant increase in hemoglobin concentration, a prolonged interval or a cessation of blood transfusion requirement developed during androgen therapy. Younger patients with cellular marrow appeared to be better responding to androgen. EEI (Effective Erythropoietic Index) formulated by Gardner and Nathan (1966) which was a helpful measurement as to whether patients with myelofibrosis would response to androgen, was evaluated in patients with aplastic anemia. It was concluded that EEI as well as ferrokinetics indices (Plasma-59Fe-disappearance rate, RBC 59Fe net incorporation) did not significantly correlate with the degree of response to androgen in aplastic anemia.

    Popov, Dmitri

    Key Words: Aplastic Anemia (AA), Pluripotential Stem Cells (PSC) Introduction: Aplastic Anemia (AA) is a disorder of the pluripotential stem cells involve a decrease in the number of cells of myeloid, erythroid and megakaryotic lineage [Segel et al. 2000 ]. The etiology of AA include idiopathic cases and secondary aplastic anemia after exposure to drugs, toxins, chemicals, viral infections, lympho-proliferative diseases, radiation, genetic causes, myelodisplastic syndromes and hypoplastic anemias, thymomas, lymphomas. [Brodskyet al. 2005.,Modan et al. 1975., Szklo et al. 1975]. Hematopoietic Acute Radiation Syndrome (or Bone marrow syndrome, or Radiation-Acquired Aplastic Anemia) is the acute toxic syndrome which usually occurs with a dose of irradiation between 0.7 and 10 Gy (70- 1000 rads), depending on the species irradiated. [Waselenko et al., 2004]. The etiology of bone morrow damage from high-level radiation exposure results depends on the radiosensitivity of certain bone marrow cell lines. [Waselenko et al. 2004] Aplastic anemia after radiation exposure is a clinical syndrome that results from a marked disorder of bone marrow blood cell production. [Waselenko et al. 2004] Radiation hematotoxicity is mediated via genotoxic and other specific toxic mechanisms, leading to aplasia, cell apoptosis or necrosis, initiation via genetic mechanisms of clonal disorders, in cases such as the acute radiation-acquired form of AA. AA results from radiation injury to pluripotential and multipotential stem cells in the bone marrow. The clinical signs displayed in reticulocytopenia, anemia, granulocytopenia, monocytopenia, and thrombocytopenia. The number of marrow CD34+ cells (multipotential hematopoietic progenitors) and their derivative colony-forming unit{granulocyte-macrophage (CFU-GM) and burst forming unit {erythroid (BFU{E) are reduced markedly in patients with AA.

    Full Text Available Objective To screen and select new drugs for aplastic anemia (AA and evaluate their clinical efficacy by clinical bioinformatics methods. Methods First, we established genome expression profiles of AA patients, and conducted similarity analyses with the pharmacogenomics database to screen and select drugs with possible efficacy. Intractable AA patients who received immunosuppressors and/or androgen for more than six months showing no clinical efficacy were enrolled in the study to evaluate therapeutic effects of the therapeutic regime. Clinical efficacy and adverse effects were evaluated after six months. Results The clinical bioinformatics results showed therapeutic effects of metformin hydrochloride on AA. Forty-three intractable AA patients (15 with severe AA were treated with metformin hydrochloride combined with cyclosporin A (CsA and stanozolol. Twenty-seven transfusion-dependent patients (100% became transfusion independent after a 6-month therapy. The hemoglobin level completely returned to normal in 37 out of 40 anemia patients (92.5%. In the 40 patients with platelet count lower than 20×109/L, the platelet count of 28 patients (90.3% increased to higher than 50×109/L. The white cell count increased to higher than 3.5×109/L in 30 out of 35 patients (88.6% with white cell count lower than 2.5×109/L. Among 40 anemic patients, 1 was found to have abnormal renal function, but it recovered to the normal range after ending CsA treatment. Eighteen patients were found to have elevated transaminase levels which were lowered to normal range after using liver protectants and reducing the dosage of stanozolol. There were no instances of hypoglycemia in all patients throughout the treatment. Conclusion Combination of metformin hydrochloride, CsA and stanozolol is effective in refractory aplastic anemia with acceptable toxicity.

    2016-09-01

    Acquired aplastic anemia (AA) is an immune-mediated bone marrow (BM) failure syndrome. Plasma thrombopoietin (TPO) levels are elevated in AA patients with reduced blood counts. However, whether elevated TPO can recover to normal level in AA patients in complete remission (CR) after efficient immunosuppressive therapy (IST) is unknown. We measured TPO levels of BM plasma in a large cohort of AA patients with focusing on patients in CR after IST. Our data showed that BM plasma TPO levels were still high in patients who had reached normal blood counts levels for a long time. We speculate that downregulated expression of MPL (TPO receptor) in HSPC (hematopoietic stem and progenitor cells) may be related to the upregulated TPO in AA. PMID:27269179

  4. Immunosuppression prior to marrow transplantation for sensitized aplastic anemia patients: comparison of TLI with TBI

    International Nuclear Information System (INIS)

    From May 1980 through July 1986, 26 patients with severe aplastic anemia, sensitized with multiple transfusions of blood products, were treated on either of two immunosuppressive regimens in preparation for bone marrow transplantation from a matched donor. There were 10 patients treated with total body irradiation (TBI), 200 cGy/fraction X 4 daily fractions (800 cGy total dose), followed by cyclophosphamide, 60 mg/kg/d X 2 d. An additional 16 patients were treated with total lymphoid irradiation (TLI) [or, if they were infants, a modified TLI or thoracoabdominal irradiation (TAI)], 100 cGy/fraction, 3 fractions/d X 2 d (600 cGy total dose), followed by cyclophosphamide, 40 mg/kg/d X 4 d. The extent of immunosuppression was similar in both groups as measured by peripheral blood lymphocyte depression at the completion of the course of irradiation (5% of initial concentration for TBI and 24% for TLI), neutrophil engraftment (10/10 for TBI and 15/16 for TLI), and time to neutrophil engraftment (median of 22 d for TBI and 17 d for TLI). Marrow and peripheral blood cytogenetic analysis for assessment of percent donor cells was also compared in those patients in whom it was available. 2/2 patients studied with TBI had 100% donor cells, whereas 6/11 with TLI had 100% donor cells. Of the five who did not, three were stable mixed chimeras with greater than or equal to 70% donor cells, one became a mixed chimera with about 50% donor cells, but became aplastic again after Cyclosporine A cessation 5 mo post-transplant, and the fifth reverted to all host cells by d. 18 post-transplant. Overall actuarial survival at 2 years was 56% in the TLI group compared with 30% in the TBI group although this was not statistically significant. No survival decrement has been seen after 2 years in either group

    Standard front-line treatment for acquired aplastic anemia (AA) for patients is either immunosuppressive therapy (IST) or bone marrow transplantation (BMT), usually from an HLA identical sibling. Whereas long-term survival is comparable with either treatment, important differences remain: IST patients may have incomplete or no recovery, are exposed to late clonal disorders and relapse of the original disease. Transplantation is a curative treatment, but patients are exposed to transplant-related complications both acute and chronic, such as chronic graft versus host disease (cGvHD). In the year 2000, a study by the European Group for Blood and Marrow Transplantation (EBMT), looked at failure free survival (FFS), in patients receiving first-line BMT from an HLA identical sibling, or the first-line IST. Young patients with low neutrophil counts benefited of the first-line BMT; the opposite was true for older patients with higher neutrophil counts; and a third intermediate group of patients had comparable survival irrespective of the first-line therapy. We have now studied a more recent cohort of patients to assess whether things have changed over the years. We have found similar results, although overall survival has improved, as a consequence of changes in the IST and BMT protocols. PMID:27278666

    Objective To investigate the efficacy of allogeneic peripheral blood stem cell transplantation (PBSCT) in the treatment of severe aplastic anemia (SAA) and severe infection. Methods A patient with SAA and pseudomonas aeruginosa septicemia was treated with PBSCT from an HLA-identical sibling with cyclophosphamide (CY) and total body irradiation (TBI) for conditioning. The patient was infused with 20.3×108/kg mononuclear cells including 61.0×106/kg CD34+cells following the conditioning regimen. Results Twenty days after PBSCT, the absolute neutrophil count (ANC) of 1.0×109/L was achieved, with platelet count >50×109/L. The donor origin of engraftment was confirmed by polymerase chain reaction (PCR) analysis of short tandem repeats at the end of the first, sixth and twelfth month. The patient's body temperature dropped to normal level when her ANC reached 0.5×109/L on day 10, and the bacterial culture of blood sample became negative subsequently. Symptoms and signs of acute or chronic graft versus host disease (GVHD) were not observed in 30 months after PBSCT. Conclusions Hematopoiesis was reconstituted shortly after PBSCT. The combination of CY and TBI and the infusion of sufficient peripheral blood stem cells may contribute to the successful engraftment. PBSCT may be considered as the first choice when hematopoietic stem cell transplantation is needed for SAA patients complicated with severe infection.

    To investigate the effect of Spatholobus Suberectus Composita (SSC) on bone marrow hematopoiesis in child aplastic anemia (AA).Methods 31 cases of AA children were treated with SSC for 24 months. The pathological changes of bone marrow and the amount of CD34 positive cells before or after treatment were compared. 14 cases of normal volunteers were enrolled as control.Results The overall response rate was 87.1% (27 in 31 patients). The volume of nucleated cell in bone marrow (27.4±9.9vol% before treatment vs 44.6±31.5 vol% after treatment), granulocytes (36.0±9.9% vs 46.2±12.9%), megakaryocytes(3.3±7.2 vs 28.5±40.5 cells in bone marrow sections) and CD34+ cells (0.9±0.5% vs 2.0±0.7%) significantly increased after treatment compared with those before treatment (P<0.01 or P<0.05).Conclusion SSC has stimulative effect, which possibly acts at the level of stem/progenitor cells, on the bone marrow hematopoesis.

    The testing kit of second generation for serum anti-HCV was used in 82 cases of aplastic anemia (AA). The results showed that positive rate was 69.4% (43/62) in the patients of AA with transfusion, this was significantly higher than that in the patients of AA without transfusion. There was no difference of anti-HCV antibody positive rate between chronic AA and acute AA (P > 0.05), incidence rate of post-transfusion hepatitis C (PTHC) in AA was 33.9% (21/62), among which the incidence rate in acute and chronic AA were 68.8% (11/16) and 21.7% (10/46) respectively (P PTHC and non-PTHC, there was no statistical difference of their transfusion volume, hemoglobin, white blood cell between these groups. Response rate of AA was lower in anti-HCV positive patients than that in negative patients (P PTHC was predominant in patients with AA. The patients with AA complicated with PTHC was liable to bleed and be infected. PTHC has been an important complication in patients with AA. The better response was obtained by TCM-WM therapy in the patients. PMID:7544177

    The decision to select hematopoietic stem cell transplantation (HSCT) or immunosuppressive therapy (IST) as initial therapy in acquired aplastic anemia (AA) is currently based on patient age and the availability of a human leukocyte antigen (HLA)-matched donor. Although IST is a promising treatment option, the ability to predict its long-term outcomes remains poor due to refractoriness, relapses, and the risk of clonal evolution. Several predictive biomarkers for response to IST have been posited, including age, gender, pre-treatment blood cell counts, cytokines, gene mutations, paroxysmal nocturnal hemoglobinuria (PNH), and telomere length (TL). While previous studies have provided substantial biological insights into the utility of IST, the prognostic power of the reported biomarkers is currently insufficient to contribute to clinical decision making. Recently, a large retrospective analysis proposed the combination of minor PNH clones and TL as an efficient predictor of IST response. Identification of a reliable predictor would provide a useful tool for determining the most appropriate treatment choice for AA patients, including up-front HSCT from HLA-matched unrelated donor. The present review summarizes studies evaluating the utility of biomarkers in predicting the clinical response to IST of patients with AA, and provides a baseline for prospective studies aimed at validating previously reported biomarkers.

    Increased expression of Fas by hematopoietic progenitors in aplastic anemia (AA) suggests that Fas/Fas ligand (FasL) system plays a key role in the formation of severe pancytopenia. To further confirm the above hypothesis, T cells from 8 patients with AA were systematically studied for their FasL's distribution pattern,releasing manner and proapoptotic activity, compared with normal resting T cells and artificially activated Tcell blasts. The results demonstrated that AA T cells abnormally expressed low levels of membrane-bound FasL and contained high levels of intracellular FasL which could be triggered to release by high-dose phytohemagglutinin (PHA) pulse-stimulation. The supernatants from the PHA-stimulated AA T cells had apparent cytotoxicity against FasL-sensitive Jurkat cells, which could be significantly inhibited by monoclonal antibody against FasL in a dose-dependent manner, or nearly completely abrogated by ultracentrifugation. The above phenomena also appeared on artificially activated T cell blasts, but this was not the case on normal resting Tcells. These results indicate that AA T cell is a type of "preactivated" T lymphocyte, characterized by overexpression of FasL, especially intracellular FasL which can be stimulated to release in bioavtive exosomesbound form. Taken together, our data provide further and direct evidence for the hypothesis that T cells might mediate the destruction of hematopietic progenitor in AA through Fas/FasL system.

    To retrospectively evaluate the outcome and toxicity of total lymphoid irradiation (TLI) based conditioning regimen for allogeneic hematopoietic stem cell transplantation (HSCT) in severe aplastic anemia (SAA) patients who experienced an engraftment failure from prior HSCT or were heavily transfused. Between 1995 and 2006, 20 SAA patients received TLI for conditioning of HSCT. All patients were multi-transfused or had long duration of disease. Fifteen (75%) patients had graft failure from prior HSCT. In 18 (90%) patients, the donors were human leukocyte antigen identical siblings. The stem cell source was the peripheral blood stem cell in 15 (75%) patients. The conditioning regimen was composed of antithymocyte globulin plus TLI with a median dose of 750 cGy in 1 fraction. The graft-versus-host disease (GVHD) prophylaxis used cyclosporine with methotrexate. With a median follow-up of 10.8 years, graft failures developed in 6 patients. Among them, 3 patients received their third HSCT to be engrafted finally. The Kaplan-Meier overall survival rate was 85.0% and 83.1% at 5 and 10 years, respectively. The incidence of acute and chronic GVHD was 20% and 20%, respectively. None of the patients have developed a malignancy after HSCT. In our study, TLI based conditioning in allogeneic HSCT was feasible with acceptable rates of GVHD in SAA patients who experienced graft failure from prior HSCT or was at a high risk of graft rejection. We achieved relatively better results of engraftment and survival with a long term follow-up.

    The present study was primarily undertaken to examine the hypothesis that mitochondrial DNA (mtDNA) mutations and telomere length may be associated with aplastic anemia (AA). Our study included a single institution analysis of 40 patients presenting with AA first diagnosed at the Affiliated Hospital of Shandong, University of Traditional Chinese Medicine between 2010 and 2013. Bone marrow and oral epithelial samples were collected from patients with AA (n=40) for mtDNA mutation and telomere length determinations. Bone marrow specimens were collected from 40 healthy volunteers as controls for the examination of telomere length. The mitochondrial genome was amplified by polymerase chain reaction (PCR), and the products were used for sequencing and analysis. We detected 146 heteroplasmic mutations in 18 genes from 40 patients with AA, including 39 silent mutations and 28 frameshift mutations. We used the gamma globin gene (HBG) as the control gene in real-time PCR to survey the relative telomere length measurements of the patients with AA and the healthy volunteers. Telomere length was expressed as the relative T/S value. We observed a negative correlation between the mtDNA non-silent mutation and the white blood cell (WBC) count, hemoglobin and platelet count. Of note, there was a positive correlation between the relative T/S value and WBC count, hemoglobin and platelet count, and a negative correlation between the non-silent mutation and the relative T/S value. We conclude that the functional impairment of the mitochondrial respiratory chain induced by mutation and telomere length shortening may play an important role in the process of hematopoietic failure in patients with AA. Additionally, mtDNA mutations and telomere length shortening influenced each other.

    Full Text Available Hepatitis associated aplastic anemia (HAAA is a rare syndrome in which severe aplastic anemia (SAA complicates the recovery of acute hepatitis (AH. HAAA is described to occur with AH caused by viral infections and also with idiopathic cases of AH and no clear etiology of liver injury. Clinically, AH can be mild to fulminant and transient to persistent and precedes the onset SAA. It is assumed that immunologic dysregulation following AH leads to the development of SAA. Several observations have been made to elucidate the immune mediated injury mechanisms, ensuing from liver injury and progressing to trigger bone marrow failure with the involvement of activated lymphocytes and severe T-cell imbalance. HAAA has a very poor outcome and often requires bone marrow transplant (BMT. The findings of immune related myeloid injury implied the use of immunosuppressive therapy (IST and led to improved survival from HAAA. We report a case of young male who presented with AH resulting from the intake of muscle building protein supplements and anabolic steroids. The liver injury slowly resolved with supportive care and after 4 months of attack of AH, he developed SAA. He was treated with IST with successful outcome without the need for a BMT.

    Macroscopic liver lesions were investigated with the use of computed tomography (CT) and radionuclide imaging (RN) in 15 aplastic anemia patients who were administered anabolic steroids for over one year and who showed no apparent physical and biochemical sign of liver tumor. In 3 patients, CT scans showed radiolucent areas in the liver. Contrast enhancements revealed these lesions to be well vascularized, suggesting they were not cysts but probably tumors. RN imaging could not demonstrate any definite space occupying lesions. Total dose of AS administered to each of the three patients exceeded 30,000 mg. It was felt that attention should be paid to the possible development of hepatic tumor when the dose of AS administered exceeds 30,000 mg.

    Recently, a growing number of reports had shown the association between mitochondrial DNA (mtDNA) sequence variants and aplastic anemia (AA). Owing to its high mutation rate, mtDNA variant had become biomarker for clinical and molecular diagnosis for AA. However, the relationship between mtDNA variant and AA was largely unknown. In this study, we reanalyzed the possible association between a "pathogenic" mutation A10055G in mt-tRNA(Gly) gene and AA, through the application of bioinformatics tool, we found that this mutation did not alter the secondary structure of tRNA(Gly), the pathogenicity scoring system indicated that the score of this mutation was only two points and belonged to a "neutral polymorphism", suggested that the role of A10055G mutation in clinical expression in AA needed to be further experimentally addressed.

    Full Text Available A aplasia de medula é uma das mais raras (Aplastic anemia (AA is one of the rarest (<1% and most serious complications of liver transplantation for fulminant non-A, non-B and non-C hepatitis. It was first described in 1987 by Stock; the mechanism involved is an immunologically mediated condition secondary to an unknown viral infection. The disease is associated with a dismal prognosis. Spontaneous recovery from acquired AA is very rare however some patients (50-70% recover after immunosuppressive therapy, such as Cyclosporin A (CsA and Antithymocyte globulin (ATG, even after liver transplantation. Another treatment option is bone marrow transplantation. We report on a child who developed AA following liver transplantation for fulminant viral hepatitis that was treated with intensive immunosuppression including CsA and ATG and achieved complete recovery.

    Full Text Available Self-renewing Hematopoietic Stem Cells (HSCs are responsible for reconstitution of all blood cell lineages. Sca-1 is the “stem cell antigen” marker used to identify the primitive murine HSC population, the expression of which decreases upon differentiation to other mature cell types. Sca-1+ HSCs maintain the bone marrow stem cell pool throughout the life. Aplastic anemia is a disease considered to involve primary stem cell deficiency and is characterized by severe pancytopenia and a decline in healthy blood cell generation system. Studies conducted in our laboratory revealed that the primitive Sca-1+ BM-HSCs (bone marrow hematopoietic stem cell are significantly affected in experimental Aplastic animals pretreated with chemotherapeutic drugs (Busulfan and Cyclophosphamide and there is increased Caspase-3 activity with consecutive high Annexin-V positivity leading to premature apoptosis in the bone marrow hematopoietic stem cell population in Aplastic condition. The Sca-1bright, that is, “more primitive” BM-HSC population was more affected than the “less primitive” BM-HSC Sca-1dim⁡ population. The decreased cell population and the receptor expression were directly associated with an empty and deranged marrow microenvironment, which is evident from scanning electron microscopy (SEM. The above experimental evidences hint toward the manipulation of receptor expression for the benefit of cytotherapy by primitive stem cell population in Aplastic anemia cases.

  7. Bone marrow transplantation for girls with aplastic anemia utilizing modified field of total lymphoid irradiation and cyclophosphamide

    International Nuclear Information System (INIS)

    A preparative regimen for allogeneic bone marrow transplantation, consisting of total lymphoid irradiation (TLI) with 750 cGy and cyclophosphamide (CY), was used in five girls with aplastic anemia. All patients received bone marrow from HLA matched/mixed lymphocyte culture negative siblings. In our regimen the 'inverted Y' field to irradiate the pelvic nodes was modified, which did not include the whole pelvic cavity in an attempt to protect the ovaries from irradiation. Although some of the pelvic nodes was supported not to be irradiated in order to protect the ovaries, engraftment occurred in all five patients including four who had been transfused prior to transplantation. All five are alive from 47 days to 1378 days (median 285 days) after transplantation without tranplantation-associated complications. The calculated dose to the ovaries was sixteen percent of the entire dose of the regimen. Both of the two evaluable patients that had received tranplantation just before or during the puberty are developing normal sex maturity including menstruation. This study suggests that our preparative regimen is effective not only for engraftment of the donor marrow but also for protecting the ovaries from irradiation. (author)

    Telaprevir and Boceprevir are the first direct acting antivirals approved for chronic hepatitis C in combination with peg-interferon alfa and ribavirin. Pancytopenia due to myelotoxicity caused by these drugs may occur, but severe hematological abnormalities or aplastic anemia (AA) have not been described. We collected all cases of severe pancytopenia observed during triple therapy with telaprevir in four Spanish centers since approval of the drug in 2011. Among 142 cirrhotic patients receiving treatment, 7 cases of severe pancytopenia (5%) were identified and three were consistent with the diagnosis of AA. Mean age was 59 years, five patients had compensated cirrhosis and two patients had severe hepatitis C recurrence after liver transplantation. Severe pancytopenia was diagnosed a median of 10 wk after the initiation of therapy. Three patients had pre-treatment hematological abnormalities related to splenomegaly. In six patients, antiviral treatment was interrupted at the onset of hematological abnormalities. Two patients died due to septic complications and one patient due to acute alveolar hemorrhage. The remaining patients recovered. Severe pancytopenia and especially AA, are not rare during triple therapy with telaprevir in patients with advanced liver disease. Close monitoring is imperative in this setting to promptly detect serious hematological disorders and to prevent further complications. PMID:25954117

    Objective: To explore the therapy to further elevate the efficacy of the treatment of chronic aplastic anemia (CAA). Methods: Forty-five patients with CCA were assigned into two groups, the 26 paporin A (CsA), and the 19 patients in the control group were treated with androgen alone, with the therapeutic course lasting for over 3 months. Changes of peripheral blood picture, and the colony productivity of burst forming unit-erythroid (BFU-E), colony forming unit-erythroid (CFU-E) and colony forming unit-granulocyte macrophage (CFU-GM) in bone marrow were observed before and after 3 months treatment. The amount of erythrocyte and platelet infusion, frequency of infection, condition of hemorrhage and relevant death were also observed. The follow-up study was conducted for over half a year. Results: The total effective rate in the treated group was 84.6%, which was significantly higher than that in the control group (52.6%, P<0.05).Levels of hemoglobin, reticulocyte, neutrophil and platelet increased after treatment in the treated group, as compared with those before treatment, with significant difference ( P<0.05), and the colony productivity of BFU-E, CFU-E and CFU-GM in bone marrow also got significantly increased ( P<0.01 ), and showed significant difference from those in the control group (P<0.05). Conclusion: Shengxuening-assisting CsA therapy is an effective measure for treatment of CAA.

    Peliosis hepatis (PH) is a condition involving benign tumors pathologically characterized by multiple blood-filled cavities, mostly affecting the liver and spleen. Androgenic-steroids are widely used in patients with bone marrow failure syndromes (e.g.: aplastic anemia) and these patients are at increased risk of developing PH. Although patients with PH are generally asymptomatic, PH can progress to liver failure and even fatal spontaneous intraabdominal hemorrhage. Therefore, early diagnosis is critical in order to prevent life-threatening complications of PH. We herein report a patient with PH which had been treated with danazol, who presented with liver dysfunction and multiple hepatic lesions on imaging studies at the time of diagnosis. Although the patient presented with disseminated intravascular coagulation (DIC), a bone marrow biopsy revealed no evidence of leukemic transformation. The patient was diagnosed as having danazol-induced PH, and these abnormalities spontaneously resolved after the discontinuation of danazol. PH is one of the most important complications of long-term administration of androgenic-steroids. Although the mechanisms remain unclear, the multiple blood-filled cavities characteristic of PH may be responsible for the development of DIC. Therefore, monitoring of coagulation markers might also be a key strategy for early diagnosis of PH. PMID:27599419

  11. Differential gene expression profile associated with the abnormality of bone marrow mesenchymal stem cells in aplastic anemia.

    Directory of Open Access Journals (Sweden)

    Jianping Li

    Full Text Available Aplastic anemia (AA is generally considered as an immune-mediated bone marrow failure syndrome with defective hematopoietic stem cells (HSCs and marrow microenvironment. Previous studies have demonstrated the defective HSCs and aberrant T cellular-immunity in AA using a microarray approach. However, little is known about the overall specialty of bone marrow mesenchymal stem cells (BM-MSCs. In the present study, we comprehensively compared the biological features and gene expression profile of BM-MSCs between AA patients and healthy volunteers. In comparison with healthy controls, BM-MSCs from AA patients showed aberrant morphology, decreased proliferation and clonogenic potential and increased apoptosis. BM-MSCs from AA patients were susceptible to be induced to differentiate into adipocytes but more difficult to differentiate into osteoblasts. Consistent with abnormal biological features, a large number of genes implicated in cell cycle, cell division, proliferation, chemotaxis and hematopoietic cell lineage showed markedly decreased expression in BM-MSCs from AA patients. Conversely, more related genes with apoptosis, adipogenesis and immune response showed increased expression in BM-MSCs from AA patients. The gene expression profile of BM-MSCs further confirmed the abnormal biological properties and provided significant evidence for the possible mechanism of the destruction of the bone marrow microenvironment in AA.

  12. Hematopoietic Stem Cell Regulation by Type I and II Interferons in the Pathogenesis of Acquired Aplastic Anemia.

    2016-01-01

    Aplastic anemia (AA) occurs when the bone marrow fails to support production of all three lineages of blood cells, which are necessary for tissue oxygenation, infection control, and hemostasis. The etiology of acquired AA is elusive in the vast majority of cases but involves exhaustion of hematopoietic stem cells (HSC), which are usually present in the bone marrow in a dormant state, and are responsible for lifelong production of all cells within the hematopoietic system. This destruction is immune mediated and the role of interferons remains incompletely characterized. Interferon gamma (IFNγ) has been associated with AA and type I IFNs (alpha and beta) are well documented to cause bone marrow aplasia during viral infection. In models of infection and inflammation, IFNγ activates HSCs to differentiate and impairs their ability to self-renew, ultimately leading to HSC exhaustion. Recent evidence demonstrating that IFNγ also impacts the HSC microenvironment or niche, raises new questions regarding how IFNγ impairs HSC function in AA. Immune activation can also elicit type I interferons, which may exert effects both distinct from and overlapping with IFNγ on HSCs. IFNα/β increase HSC proliferation in models of sterile inflammation induced by polyinosinic:polycytidylic acid and lead to BM aplasia during viral infection. Moreover, patients being treated with IFNα exhibit cytopenias, in part due to BM suppression. Herein, we review the current understanding of how interferons contribute to the pathogenesis of acquired AA, and we explore additional potential mechanisms by which interferons directly and indirectly impair HSCs. A comprehensive understanding of how interferons impact hematopoiesis is necessary in order to identify novel therapeutic approaches for treating AA patients. PMID:27621733

    Full Text Available Severe aplastic anemia (SAA is probably an immune-mediated disorder, and immunosuppressive therapy is recommended for patients with no available donor for bone marrow transplant. Between October 1984 and November 1987, 25 consecutive children and adolescents with SAA with no HLA-compatible marrow donor received equine antithymocyte globulin (ATG (15 mg kg-1 day-1 for 10 days. The patients were evaluated 6 weeks, 6 months, and 12 months after starting ATG treatment. Thereafter, patients were evaluated yearly until July 1998. Median age was 10 years (range, 1.5-20 years, granulocyte counts on referral ranged from 0.032 to 1.4 x 10(9/l (median 0.256 x 10(9/l, and 12 patients had granulocyte counts <0.2 x 10(9/l. At a median follow-up of 9.6 years (range, 8.6-11.8 years, 10 patients (40% remained alive with good marrow function. No morphologic evidence of hematological clonal disorders has been observed, although two patients probably have acquired clonal chromosomal abnormalities (trisomy 8 and del(6q21, respectively. Responses to ATG were observed between 6 weeks and 6 months from the start of treatment in 60% of evaluable patients. The response rate was not different in patients whose granulocyte count at diagnosis was <0.2 x 10(9/l, or in those who were <10 years of age. This study supports the view that, when compared with supportive measures, ATG is an effective treatment for children or adolescents with SAA. Although these results are inferior to those reported for marrow transplantation or more intensive immunosuppressive regimens, these patients who responded to ATG are long-term survivors with stable peripheral blood counts and a low rate of relapse.

    Full Text Available Allogeneic hematopoietic stem cell transplantation (AHSCT is the treatment of choice for young patients with severe aplastic anemia (SAA. The association of antithymocyte globulin (ATG and cyclophosphamide (CY is the most frequently used conditioning regimen for this disease. We performed this retrospective study in order to compare the outcomes of HLA-matched sibling donor AHSCT in 41 patients with SAA receiving cyclophosphamide plus ATG (ATG-CY, N = 17 or cyclophosphamide plus busulfan (BU-CY, N = 24. The substitution of BU for ATG was motivated by the high cost of ATG. There were no differences in the clinical features between the two groups, including age, gender, cytomegalovirus status, ABO match, interval between diagnosis and transplant, and number of total nucleated cells infused. No differences were observed in the time to neutrophil and platelet engraftment, or in the risk of veno-occlusive disease and hemorrhage. However, there was a higher risk of mucositis in the BU-CY group (71 vs 24%, P = 0.004. There were no differences in the incidence of neutrophil and platelet engraftment, acute and chronic graft-versus-host disease, and transplant-related mortality. There was a higher incidence of late rejection in the ATG-CY group (41 vs 4%, P = 0.009. Although the ATG-CY group had a longer follow-up (101 months than the BU-CY group (67 months, P = 0.04, overall survival was similar between the groups (69 vs 58%, respectively, P = 0.32. We conclude that the association BU-CY is a feasible option to the conventional ATG-CY regimen in this population.

    Summary To summarize (he research progress of iclomcrc length and telomerase activity in acquired aplastic anemia(Aaa). A full text database system based on PUBMED and CNK1 was adopted for searching relevant literature from 1996 to 2012 with the key words of "telomere.telomerase and acquired aplastic anemia". Criterion for data selection-The literature about advances of telomere, telomerase and acquired aplastic anemia was selected for a-nalysis. According to the standard.236 articles were analyzed. Acquired aplastic anemia is hone marrow failure syndromes that mainly results from immune-mediated destruction of hematopoiesis. About one-third of patients with Aaa have short telomeres in peripheral white blood cells.some of which have heterozygous mutations in genes encoding the telomerase components of TERT or TERC Clinical observation found that most Aaa patients with telomere shortening were insensitive to immunosuppressive therapy;the disease duration increased and the prognosis was poor. Short telomeres may cause malignant clonal diseases in the advanced .stage.such as MDS.AML. Treatment plan for these Aaa patients with shortening telomere should he adjusted. They must undergo haematopoietic stem cell transplant ( HSCT) as soon as possible,and family donors with relevant mutations must he avoided. The Aaa patients with telomere related abnormality are different from other patients regarding pathological mechanism,disease progress, treatment and prognosis. Only a small proportion of these eases could be explained by TERT or TERC mutation. Other mutation or causes may remain unknown .

    Full Text Available Although bone marrow transplantation (BMT from an HLA identical sibling is considered as treatment of choice in pediatric patients with severe aplastic anemia (SAA, a significant number of them experience graft failure (GF after BMT. We report a case of an 8-year-old male patient with SAA who presented with a complicated posttransplant course due to parvovirus B19 infection and GF. A subsequent attempt to support the graft by antithymocyte globulin (ATG and a peripheral stem cell boost resulted in transitory autologous recovery of hematopoiesis followed by mixed chimerism, supported by donor lymphocyte infusions (DLIs and finally graft rejection with relapse of SAA. Permanent complete chimerism was achieved by a second BMT. Dynamics of graft function, measured by a single nucleotide polymorphism (SNPs analysis, are discussed.

    Full Text Available Abstract Background Allogeneic hematopoietic stem cell transplantation (allo-HSCT is an effective treatment for severe aplastic anemia (SAA. However, graft failure and graft-versus-host disease (GVHD are major causes of the early morbidity in Allo-HSCT. Methods To reduce graft failure and GVHD, we treated fifteen patients with SAA using high- dose of HSCT with both G-CSF mobilized PB and BMSCs from HLA-identical siblings to treat patients with SAA. Results All patients had successful bone marrow engraftment. Only one patient had late rejection. Median time to ANC greater than 0.5 × 109/L and platelet counts greater than 20 × 109/L was 12 and 16.5 days, respectively. No acute GVHD was observed. The incidence of chronic GVHD was 6.67%. The total three-year probability of disease-free survival was 79.8%. Conclusion HSCT with both G-CSF mobilized PB and BMSCs is a promising approach for heavily transfused and/or allo-immunized patients with SAA.

    A 19-year-old woman complaining of fever and a sore throat was diagnosed with very severe aplastic anemia (AA) by bone marrow examination at a local hospital. Despite administration of antibiotics and granulocyte-colony stimulating factor to treat the soft tissue infection in her neck, her neutrophil count showed no increase. Because emergent allogeneic stem cell transplantation (SCT) was necessary, she was referred to our hospital. On admission, computed tomography revealed right-sided severe pharyngitis and lymphadenitis causing tracheal stenosis, and emergent intubation was required the next day. Granulocyte transfusion therapy (GTX) from related donors coupled with broad-spectrum antibiotic administration controlled the otherwise overwhelming infection. The patient received allogeneic peripheral blood SCT using a reduced-intensity conditioning regimen. After allogeneic SCT, successful engraftment was obtained. She was discharged from the hospital 59 days after allogeneic SCT. She remains alive and well, as of the latest follow up. This case clearly demonstrates that GTX is useful for controlling severe infection and enables patients with severe AA to receive allogeneic SCT safely. PMID:27169447

    To confirm the safety and efficacy of an indigenous equine antithymocyte globulin (eATG) along with cyclosporine in Indian subjects with acquired aplastic anaemia. Subjects >2 years old with acquired aplastic anaemia were enrolled at six hospitals between April 2011 and February 2013, after approval from respective Ethics Committees. Equine ATG at a dose of 40 mg/kg/day was infused for 4 days. Efficacy analysis defined a priori, was in subjects, who had completed eATG treatment and followed-up on day 90 and/or 180. Complete response (CR) was defined as-transfusion independent, haemoglobin ≥11 g/dL, absolute neutrophil count (ANC) >1.5 10(9)/L and platelet ≥150 10(9)/L; partial response (PR) was transfusion independent, haemoglobin ≥8 g/dL, ANC >0.5 10(9)/L and platelet ≥20 10(9)/L; non responders were transfusion dependent. Lymphocyte subsets (CD 2, 3, 4 and 8) in the blood were tested on days 0 (pre eATG infusion), 3, 5, 7, 14 and 21 after eATG. Of the 30 subjects (two children pneumonia, one was withdrawn after the first dose of eATG due to jaundice and eight were lost to follow-up. The median age was 30 (9-58) years and weight was 57 (26-84) kg. On day 90, 12 of 30 subjects responded (CR 1, PR 11) and 15 of 30 (CR 2, PR 13) on day 180. The most common adverse event was fever related to eATG infusion. There were two serious adverse events (acute renal failure, febrile neutropenia) and both recovered with treatment. There were no unusual adverse events noted during the study period. Blood T lymphocytes showed a mean decrease of 91 % from baseline that recovered by day 21. We conclude that eATG is safe and in combination with cyclosporine showed overall response in 50 % of enrolled subjects. The trial was registered with the clinical trial registry-india (Registration no. CTRI/2012/03/002498). PMID:25825555

    Hematopoietic stem cell transplantation (HSCT) is a curative therapy for severe aplastic anemia (SAA); however, the optimal conditioning regimen for HSCT with an unrelated donor has not yet been defined. A previous study using a fludarabine (FLU), cyclophosphamide (Cy), and antithymocyte globulin (ATG) conditioning regimen (study A: 50 mg/kg Cy once daily i.v. on days -9, -8, -7, and -6; 30 mg/m(2) FLU once daily i.v. on days -5, -4, -3, and -2; and 2.5 mg/kg of ATG once daily i.v. on days -3, -2, and -1) demonstrated successful engraftment (100%) but had a high treatment-related mortality rate (32.1%). Therefore, given that Cy is more toxic than FLU, we performed a new phase II prospective study with a reduced-toxicity regimen (study B: 60 mg/kg Cy once daily i.v. on days -8 and -7; 40 mg/m(2) FLU once daily i.v. on days -6, -5, -4, -3, and -2; and 2.5 mg/kg ATG once daily i.v. on 3 days). Fifty-seven patients were enrolled in studies A (n = 28) and B (n = 29), and donor type hematologic recovery was achieved in all patients in both studies. The overall survival (OS) and event-free survival (EFS) rates of patients in study B was markedly improved compared with those in study A (OS: 96.7% versus 67.9%, respectively, P = .004; EFS: 93.3% versus 64.3%, respectively, P = .008). These data show that a reduced-toxicity conditioning regimen with FLU, Cy, and ATG may be an optimal regimen for SAA patients receiving unrelated donor HSCT. PMID:27090956

    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.

    Full Text Available B-cell lymphoproliferative disorder (B-LPD is generally characterized by the proliferation of Epstein-Barr virus (EBV-infected B lymphocytes. We here report the development of EBV-negative B-LPD associated with EBV-reactivation following antithymocyte globulin (ATG therapy in a patient with aplastic anemia. The molecular autopsy study showed the sparse EBV-infected clonal T cells could be critically involved in the pathogenesis of EBV-negative oligoclonal B-LPD through cytokine amplification and escape from T-cell surveillances attributable to ATG-based immunosuppressive therapy, leading to an extremely rare B-cell-rich T-cell lymphoma. This report helps in elucidating the complex pathophysiology of intractable B-LPD refractory to rituximab.

All relevant publications were searched through December 2015. Odds ratio (OR), risk ratio (RR), and 95% confidence intervals (CI) for the comparison between case-control or cohort studies were evaluated. Finally, 24 articles were identified. For HLA-DRB1*15 and HLA-DRB1*15:01, the OR (95% CI) was 2.24(1.33-3.77), P 0.05). Sensitivity analyses revealed that the results were statistically robust. The meta-analysis suggested that HLA-DRB1*15 and HLA-DRB1*15:01 polymorphisms might be associated with increased AA risk in Asians. IST might be more effective in HLA-DRB1*15+ and HLA-DRB1*15:01+ Asian patients with AA than in HLA-DRB1*15- and HLA-DRB1*15:01- Asian patients with AA. Future studies with adequate methodological quality on gene-gene and gene-environment interactions and gene treatment may yield valid results. PMID:27611583

    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.

    Objective To examine the association of mitochondrial DNA ( mtDNA) mutations with telomere length in patients with aplastic anemia ( AA) . Methods Bone marrow and oral epi-thelial samples were collected from 45 patients diagnosed as having AA between 2010-2014 for de-tection of mtDNA mutation and telomere length. Complete sequence analysis of mtDNA revealed 151 mutations in 18 genes, including 40 silent mutations and 28 frameshift mutations. Moreover, the relative length of telomere ( relative T/S value) was detected in AA patients and healthy volunteers, with HBG as internal control gene. Results Non-silent mutation of mtDNA was negatively correla-ted with the WBC count, hemoglobin level and platelet count. Relative T/S value was positively correlated with the WBC count, hemoglobin level and platelet count, and a negative correlation was found between the non-silent mutation of mtDNA and relative T/S value. Conclusion Mutation-caused functional impairment of the mitochondrial respiratory chain and telomere length shortening may play important roles in the process of hematopoietic failure in AA patients. Additionally, mtD-NA mutations and telomere length shortening influence each other.%目的:研究再生障碍性贫血患者线粒体突变及端粒长度情况,了解两者间的相关性。方法选择2010~2014年确诊为再生障碍性贫血的患者45例,留取骨髓及口腔黏膜上皮标本以进行线粒体DNA ( mitochondrial DNA, mtDNA)突变和端粒长度的检测。线粒体全测序检测到了151个突变,分布在18个基因中,其中包括了40个沉默突变及28个框移突变。同时使用HBG作为内参基因,检测了再障患者和健康志愿者端粒的相对长度( relative T/S value,端粒长度)。结果分析发现非沉默突变的mtDNA突变与白细胞数、血红蛋白水平及血小板数成负相关。端粒长度与白细胞数、血红蛋白水平及血小板数成正相关性,而且非沉默突变的mtDNA突变与端粒长

  15. Successful allogeneic stem cells transplantation in severe aplastic anaemia complicated by dengue fever

    International Nuclear Information System (INIS)

    Aplastic anaemia is characterized by severe compromise of haematopoiesis and hypocellular bone marrow. Haemorrhagic episodes in patients with aplastic anemia occur usually secondary to thrombocytopenia and require frequent support with platelet concentrates and other blood products. Infection with dengue virus (particularly dengue sero type-2 of South Asian genotype) is associated with dengue haemorrhagic fever. Dengue infection further worsens the disease process in patients with aplastic anaemia due to uncontrolled haemorrhagic diathesis and major organ failure, which may prove fatal in these already immunocompromised patients, if not treated in time. Recent epidemics of dengue haemorrhagic fever has not only affected the southern region of our country but also spread to other areas of the country. With this background, we report a case of aplastic anaemia complicated by dengue haemorrhagic fever who achieved successful engraftment after allogeneic stem cell transplantation from sibling brother and is having normal healthy post transplant life.

    BACKGROUND:For pediatric patients with aplastic anemia in China, it is difficult to find human leucocyte antigen-matched sibling donors that are mostly replaced by parental donors. OBJECTIVE:To retrospectively analyze the clinical efficacy and safety of parental haploidentical peripheral blood hematopoietic stem cel transplantation in children with relapsed and refractory severe aplastic anemia. METHODS:Seventeen children with relapsed and refractory severe aplastic anemia who had no matched sibling or unrelated donor and failed to respond to immunosuppressive therapy were subjected to parental haploidentical peripheral blood hematopoietic stem cel transplantation. A conditioning regimen of fludarabine+cyclophosphamide+rabbit anti-human thymocyte immunoglobulin antibody and the triple therapy of methotrexate, cyclosporine A and mycophenolate mofetil were applied to prevent graft-versus-host disease. RESULTS AND CONCLUSION: (1) Of the 17 children, 16 cases (94%) reached hematopoietic reconstitution, and the median time of neutrophils≥ 0.5×109/L and platelets≥ 20×109/L was 13 (11-15) days and 17 (12-28) days, respectively. (2) Incidence of acute graft-versus-host disease was 47% (8 of 17 cases), including 29% (5/17) of grades I-II and 18% (3/17) of grades III-IV. Incidence of chronic graft-versus-host disease was 41% (7/17). (3) With a median folow-up duration of 268 (43-753) days, the overal survival rate was 70.6% (12/17). Five dead cases (29%) belonged to transplantation-related death, including one case of fungal skin infections, one case of graft-versus-host disease, three cases of severe lung infection. No relapse case was reported. These findings indicate that if there are no matched sibling or unrelated donors and the immunosuppression effect is poor, parental haploidentical peripheral blood hematopoietic stem cel transplantation is a safe and effective salvage treatment for children with relapsed and refractory severe aplastic anemia.%移

    Objective To evaluate the efficacy of antithymocyte globulin (ATG) based immunosupression therapy for childhood aplastic anemia, to reduce the adverse effects and to observe the long-term outcome. Method Thirty-five children with aplastic anemia (AA) were enrolled in this study.Six of the cases had very severe AA (VSAA), 11 had severe AA (SAA)-Ⅰ, 8 had SAA-Ⅱ and 10 had moderate AA (MAA). All these patients were treated with ATG plus Cyclosporin A (CSA). The following measures were taken during the ATG therapy: infection of the patients had been controlled before ATG treatment. Comprehensive anti-allergic measures were implemented. Close attention was paid to the hemorrhage related with platelet reduction caused by ATG and severe infection of the patients. Result Shortly after the ATG usage, all the patients had a significant decrease of absolute peripheral lymphoblast count by more than 60 percent. With a mean follow-up time of 28 months, the total effective rate was 77.14% ( 27/35), significant response rate was 57.14%(20/35). There was no significant difference among VSAA, SAA and MAA groups in the response rate. Adverse reactions included the following:① 48.6% (17/35) patients presented mild anaphylactoid reaction during the first day of ATG treatment; ②42.9%(15/35) cases presented serum sickness 5-11 days after the last dose of ATG with a mean duration of 3. 6 days, all the patients were cured effectively with methylprednisolone; ③25.7% (9/35)patient's peripheral blood platelet count was reduced, might be caused by ATG, to below 10 × 109/L, but no patient had severe hemorrhagic complication after platelet transfusion was performed; ④22.9% ( 8/35 ) of patients got infection within a month after ATG therapy, including 3 cases with clinical septicemia, all the 3 cases recovered after antibiotics treatment. There was no ATG treatment-related death in this series. Conclusion ATG is a very effective therapy for children with SAA and MAA

    Full Text Available Fanconi Anemia (FA is a rare autosomic recessive and X-linked disease with chromosomal instability after exposure to crosslinking agents as the hallmark. Clinical features of FA are somatic malformations, progressive bone marrow failure and cancer proneness, however there is wide clinical heterogeneity. The symptom most frequently and early associated with morbidity and mortality is progressive pancytopenia in the first decade of life although acute myelogenous leukemia (AML or myelodysplastic syndrome (MDS can appear before aplastic anemia. Squamous cell carcinoma (SCC of the head-neck, intestinal or genital tract has a very high incidence in FA and can appear at young age. This paper will focus on treatment of bone marrow failure in FA.

We investigated the use of traditional Chinese medicine (TCM for the treatment of intractable anemia. Method: Placenta Hominis (PH, steam boiled and roasted, and Cervi Cornus Colla (deer antler glue has been used in China for hundreds of years to treat anemia. After consent was obtained, we prescribed these two materials for a 74-year-old female with aplastic anemia and a 26-year-old male with presumably a virus-induced anemia. Concomitant conventional therapy was continued in both patients as prescribed by their respective attending physicians. Conclusion: Conventional therapy with steroid hormones, immunosuppressive drugs, platelet and erythrocyte transfusions were not effective in these patients. In addition, both patients suffered from serious side effects. In two patients, ingestion of Placenta Hominis and Cervi Cornus Colla with TCM prescriptions increased the platelet and enhanced the hemoglobin concentration in several months of therapy accompanied by a dramatic improvement in quality of life. The addition to conventional therapy of PH and Cervi Cornus Colla, the latter of which is very easy to obtain, may be one of the potentially advantageous choices in case of otherwise intractable anemia.Keywords: placenta, antler glue, Cervi Cornus Colla, anemia, aplastic anemia

    2011-01-01

    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.

  17. Inborn anemias in mice

    International Nuclear Information System (INIS)

    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 α-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

    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...

    Anemia is a common problem in primary care. Classification based on mean cell volume narrows the differential diagnosis and directs testing. A marked macrocytosis is characteristic of vitamin B12 and folate deficiencies, certain medications, and primary bone marrow disorders. The three most common causes of microcytic anemia are iron deficiency, thalassemia trait, and anemia of inflammation. Additional laboratory testing is required for diagnosis. Determination of the rate of development of anemia and examination of a blood smear may provide diagnostic clues to guide more specialized testing. Diagnosis of iron, vitamin B12, or folate deficiency mandates determination of the underlying cause. PMID:27212091

    Anemic syndrome in childhood requires a diagnosis and urgent treatment guided by systematic protocols that can avoid unnecessary additional testing. The case of a 4 year-old girl with fatigue and intermittent fever of 7 days duration, accompanied by abdominal pain is presented. She had regular general health status, with mucocutaneous jaundice, a grade III/VI/iv murmur, and painful abdomen with hepatosplenomegaly. The blood analysis showed a hypo-regenerative anemia with increased LDH and indirect bilirubin. The Coombs Test was negative, with spherocytes being observed in the peripheral blood smear. The IgM and IgG were positive for parvovirus B19 IgM and Epstein Barr virus, leading to the diagnosis of aplastic crisis in a patient with hereditary spherocytosis. No specific treatment was required. Under the suspicion of anemic syndrome in emergencies, the ABCDE sequence must be followed. Through the history, physical examination and basic laboratory tests, an initial diagnostic approach can be made. Specific etiological tests should be based on this first study. PMID:24629905

    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. PMID:27352093

    2015-10-01

    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.

    Full Text Available The prevalence of anti-human parvovirus B19 IgG antibodies was determined in sera from 165 chronic hemolytic anemia patients, receiving medical care at Instituto Estadual de Hematologia (IEHE, Rio de Janeiro, during the year of 1994. This sample represents around 10% of the chronic hemolytic anemia patients attending at IEHE. Most of these patients (140 have sickle cell disease. Anti-B19 IgG antibodies were detected in 32.1% of patients. No statistically significant difference (p > 0.05 was seen between IgG antibody prevalence in male (27.8% and female (35.5% patients. Anti-B19 IgG antibodies were more frequent in older (37.6% than younger (28.2% than 20 years old patients, although this difference had no statistical significance (p > 0.05. Anti-B19 IgG antibody prevalence showed that 67.9% of patients enrolled in the study were susceptible to B19 acute infection. With the aim to detect acute B19 infection, patients follow up continued until February 1996. During this period four patients presented transient aplastic crisis due to human parvovirus B19 as confirmed by the detection of specific IgM antibodies. All four patients were younger than 20 years old, and 3 were younger than 10 years old. Three of them were sickle cell disease patients. Three of the four acute B19 infection occurred during 1994 springtime.

Unlike when anemia occurs in younger adults, the cause of anemia in the elderly is oftentimes not readily apparent or attributable to a single cause. However, this commonly observed form of anemia in the elderly (termed unexplained anemia [UA]) can generally be dissected to its root causes, which include renal insufficiency, inflammation, testosterone deficiency, and stem cell proliferative decline.

  8. Megaloblastic anemia in Japan

    Directory of Open Access Journals (Sweden)

    Taguchi,Hirokuni

    1978-08-01

    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.

  9. Aplastic anaemia after exposure to a weed killer, 2-methyl-4-chlorphenoxyacetic acid.

    1975-01-01

    A 64-year-old farmer developed aplastic anaemia after exposure to 2-methyl-4-chlorphenoxyactic acid while spraying weed killer. Muscular weakness, haemorrhagic gastritis and slight signs of liver damage occurred at the same time. All these symptoms, including blood dyscrasia , are consistent with those described as toxic effects of chlorphenoxyacetic acids in animal experiments. A causal relationship between aplastic anaemia and the 2-methyl-4-chlorphenoxyacetic acid thus seems probable. The anaemia was reversible, but the case serves as a warning that careful safety measures are required during the use of chlorphenoxyacetic acids and related compounds. PMID:804793

    Autoimmune hemolytic anemia is a rare condition in children which differs from the adult form. It is defined by immune-mediated destruction of red blood cells caused by autoantibodies. Characteristics of the autoantibodies are responsible for the various clinical entities. Classifications of autoimmune hemolytic anemia include warm autoimmune hemolytic anemia, cold autoimmune hemolytic anemia, and paroxysmal cold hemoglobinuria. For each classification, this review discusses the epidemiology, etiology, clinical presentation, laboratory evaluation, and treatment options. PMID:26575109

    Background CD4+ T cells play a crucial role in the pathogenesis of aplastic anaemia. However, the mechanisms of over-proliferation, activation, infiltration of bone marrow and damage to haematopoietic cells of CD4+ T cells in aplastic anaemia are unclear. Therefore, we screened differentially expressed genes of bone marrow CD4+ T cells of aplastic anaemia patients and normal donors by suppressive subtractive hybridization to investigate the pathogenesis of aplastic anaemia.Methods The bone marrow mononuclear cells of a first visit aplastic anaemia patient and a healthy donor of the same age and sex were isolated using lymphocyte separating medium by density gradient centrifugation. With the patients as "tester" and donor as "driver", their CD4+T cells were separated with magnetic bead sorting and a cDNA library established by suppressive subtractive hybridization. Then 15 of the resulting subtracted cDNA clones were randomly selected for DNA sequencing and homological analysis. With semiquantitative RT-PCR, bone marrow samples from 20 patients with aplastic anaemia and 20 healthy donors assessed the expression levels of differentially expressed genes from SSH library.Results PCR detected 89 clones in the library containing an inserted fragment of 100 bp to 700 bp. Among 15 sequenced clones, 12 were known genes including 3 repeated genes. Compared with normal donors, there were 9/12 genes over-expressed in bone marrow CD4+T cells of patients with aplastic anaemia. The effects of these genes included protein synthesis, biology oxidation, signal transduction, proliferative regulation and cell migration. Not all these genes had been reported in the mechanisms of haematopoietic damage mediated by CD4+ T cells in aplastic anaemia.Conclusions Screening and cloning genes, which regulate functions of CD4+ T cells, are helpful in elucidating the mechanisms of over proliferation, activation, infiltrating bone marrow and damaging haematopoietic cells of CD4+ T cells in

    Anca Ghiațău

    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.

Nor did anemia established any association with dengue (P = 0.185 or JE IgG antibody (P = 0.277. IgG status of dengue and JE could be used as proxy markers of any past subclinical infection (includes clinically manifested cases also. Further studies in large settings and other areas could be done to validate the results. This was the first study of its kind in such settings.

  10. Erythroblast transferrin receptors and transferrin kinetics in iron deficiency and various anemias

    Muta, K.; Nishimura, J.; Ideguchi, H.; Umemura, T.; Ibayashi, H.

    1987-06-01

    To clarify the role of transferrin receptors in cases of altered iron metabolism in clinical pathological conditions, we studied: number of binding sites; affinity; and recycling kinetics of transferrin receptors on human erythroblasts. Since transferrin receptors are mainly present on erythroblasts, the number of surface transferrin receptors was determined by assay of binding of /sup 125/I-transferrin and the percentage of erythroblasts in bone marrow mononuclear cells. The number of binding sites on erythroblasts from patients with an iron deficiency anemia was significantly greater than in normal subjects. Among those with an aplastic anemia, hemolytic anemia, myelodysplastic syndrome, and polycythemia vera compared to normal subjects, there were no considerable differences in the numbers of binding sites. The dissociation constants (Kd) were measured using Scatchard analysis. The apparent Kd was unchanged (about 10 nmol/L) in patients and normal subjects. The kinetics of endocytosis and exocytosis of /sup 125/I-transferrin, examined by acid treatment, revealed no variations in recycling kinetics among the patients and normal subjects. These data suggest that iron uptake is regulated by modulation of the number of surface transferrin receptors, thereby reflecting the iron demand of the erythroblast.

    We here report the initiation of hematopoietic recovery in congenitally hypoplastic S1/S1d mice by the cytotoxic ablation of cells bearing the natural killer (NK) phenotype (NK 1.1+). The most striking finding was the early several-fold increase in the cycling fraction of stem and progenitor cells (with the exception of progenitors committed to megakaryocytopoiesis) in the anti-NK 1.1+ antibody-treated group. This increase resulted in an early, complete restoration of total marrow cellularity to the normal (+/+) littermate level. Our data suggest that NK 1.1+ cells exert functions critical to the negative control of hematopoietic cell proliferation in S1/S1d mice.

  13. HEMOGLOBIN PRODUCTION FACTORS IN THE HUMAN LIVER : ANEMIAS, HYPOPROTEINEMIA, CIRRHOSIS, PIGMENT ABNORMALITIES, AND PREGANCY.

    Human liver tissue has been assayed to determine the amount of hemoglobin production factors in normal and abnormal states. Standardized dogs made anemic by blood removal have been used in this biological assay. Normal animal liver as control is rated as 100 per cent. Normal human liver tissue as compared with the normal animal control contains more of these hemoglobin production factors-a biological assay ratio of 120 to 160 per cent. Infections, acute and chronic, do not appear to modify these values, the concentration of hemoglobin-producing factors falling within the normal range. Pernicious anemia and aplastic anemia both show large liver stores of hemoglobin-producing factors-a biological assay ratio of 200 to 240 per cent. Therapy in pernicious anemia reduces these liver stores as new red cells are formed. Secondary anemia presents a low normal or subnormal liver store of hemoglobin-producing factors-an assay of 60 to 130 per cent. Hemochromatosis, erythroblastic anemia, and hemolytic icterus in spite of large iron deposits in the liver usually show a biological assay which is normal or close to normal. Polycythemia shows low reserve stores of hemoglobin-producing factors. Leukemias present a wide range of values discussed above. Hypoproteinemia almost always is associated with low reserve stores of hemoglobin-producing factors in the liver-biological assays of 60 to 80 per cent. Hypoproteinemia means a depletion of body protein reserve stores including the labile protein liver reserves-a strong indication that the prehemoglobin material (or globin) is related to these liver stores. Pregnancy, eclampsia, and lactation all may present subnormal liver stores of hemoglobin-producing factors. Exhaustion of protein stores lowers the barrier to infection and renders the liver very susceptible to many toxic substances. It should not be difficult to correct hypoproteinemia under these conditions and thus relieve the patient of a real hazard.

    Full Text Available Thiamine Responsive megaloblastic anemia in DIDMOA (Wolfram syndrome has an autosomal- recessive mode of inheritance . Megaloblastic anemia and sideroblastic anemia is accompanied by diabetes insipidus (DI, diabetes mellitus (DM ,optic atrophy (OA and deafness (D. Neutropenia and thrombocytopenia are also present. We report a 7 month old girl with congenital macrocytic anemia; a rare clinical feature of Wolfram,s syndrome with increased plasma levels of blood glucose, both of which dramatically responded to administration of thiamine in large doses . The patient also had neurosensorial deafness, but no improvement was observed in the deafness. We presented the case because thiamine-responsive megaloblastic anemia is a rare clinical presentation of Wolfram syndrome and after institution of treatment with thiamine, the anemia and hyperglycemia returned to normal.

  15. Understanding anemia of chronic disease.

    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.

    A 12-year-old Caucasian female presented to her family physician with an old complaint of anemia and a new complaint of failure to grow. The anemia, first observed four years previously, had been diagnosed as iron deficiency, but had never satisfactorily responded to adequate iron therapy. Investigation of the failure to grow resulted in a diagnosis of hypothyroidism with related normochromic normocytic anemia.

    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.

  18. Iron Deficiency Anemia in Pregnancy.

    2015-10-01

    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.

    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

    Full Text Available Allo-anti-M often has an immunoglobulin G (IgG component but is rarely clinically significant. We report a case of hemolytic disease of the fetus and newborn along with prolonged anemia in newborn twins that persisted for up to 70 days postbirth. The aim was to diagnose and successfully manage hemolytic disease of newborn (HDN due to maternal alloimmunization. Direct antiglobulin test (DAT, antigen typing, irregular antibody screening and identification were done by polyspecific antihuman globulin cards and standard tube method. At presentation, the newborn twins (T1, T2 had HDN with resultant low reticulocyte count and prolonged anemia, which continued for up to 70 days of life. Blood group of the twins and the mother was O RhD positive. DAT of the both newborns at birth was negative. Anti-M was detected in mothers as well as newborns. Type of antibody in mother was IgG and IgM type whereas in twins it was IgG type only. M antigen negative blood was transfused thrice to twin-1 and twice to twin-2. Recurring reduction of the hematocrit along with low reticulocyte count and normal other cell line indicated a pure red cell aplastic state. Anti-M is capable of causing HDN as well as prolonged anemia (red cell aplasia due to its ability to destroy the erythroid precursor cells. Newborns with anemia should be evaluated for all the possible causes to establish a diagnosis and its efficient management. Mother should be closely monitored for future pregnancies as well.

  6. 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.

    Hematopoietic stem cell transplantation (HSCT) is curative for hematological manifestations of Fanconi anemia (FA). We performed a retrospective analysis of 22 patients with FA and aplastic anemia, myelodysplastic syndrome or acute myelogenous leukemia who underwent a HSCT at Memorial Sloan Kettering Cancer Center and survived at least 1 year post HSCT. Patients underwent either a TBI- (N=18) or busulfan- (N=4) based cytoreduction followed by T-cell-depleted transplants from alternative donors. Twenty patients were alive at time of the study with a 5- and 10-year overall survival of 100 and 84% and no evidence of chronic GvHD. Among the 18 patients receiving a TBI-based regimen, 11 (61%) had persistent hemochromatosis, 4 (22%) developed hypothyroidism, 7 (39%) had insulin resistance and 5 (27%) developed hypertriglyceridemia after transplant. Eleven of 16 evaluable patients (68%), receiving TBI, developed gonadal dysfunction. Two patients who received a TBI-based regimen died of squamous cell carcinoma. One patient developed hemochromatosis, hypothyroidism and gonadal dysfunction after busulfan-based cytoreduction. TBI appears to be a risk factor for malignant and endocrine late effects in the FA host. Multidisciplinary follow-up of patients with FA (including cancer screening) is essential for early detection and management of late complications, and improving long-term outcomes. PMID:26999465

    2011-01-01

    Hepatitis-associated aplastic anaemia (HAAA) is an uncommon but distinct variant of aplastic anaemia in which pancytopenia and bone marrow failure appears 2-3 months after an acute attack of hepatitis. Although bilateral vision loss may rarely be the initial presentation of aplastic anaemia, no such report is known in HAAA. Here the authors report such a case presenting with large premacular subhyaloid haemorrhages secondary to severe anaemia and thrombocytopenia. Anaemic hypoxic damage to the vessel wall together with increased cardiac output and low platelet counts are interacting causal factors in the development of bleeding. Though these haemorrhages are benign and usually improve spontaneously, the presence of blood may cause permanent macular changes before it resolves. Posterior hyaloidotomy enabled rapid resolution of premacular subhyaloid haemorrhage thereby restoring vision and preventing need for vitreo-retinal surgery. These patients should be advised to refrain from valsalva manoeuvres, ocular rubbing and vigorous exercise to prevent ocular morbidity. PMID:22674943

    Fanconi anemia is a genetic bone marrow failure syndrome. The current treatment options are suboptimal and do not prevent the eventual onset of aplastic anemia requiring bone marrow transplantation. We previously showed that resveratrol, an antioxidant and an activator of the protein deacetylase Sirt1, enhanced hematopoiesis in Fancd2 mutant mice and improved the impaired stem cell quiescence observed in this disease. Given that Sirt1 is important for the function of hematopoietic stem cells, we hypothesized that Sirt1 activation may improve hematopoiesis. Indeed, Fancd2(-/-) mice and wild-type mice treated with the selective Sirt1 activator SRT3025 had increased numbers of hematopoietic stem and progenitor cells, platelets and white blood cells. SRT3025 was also protective against acetaldehyde-induced hematopoietic damage. Unlike resveratrol, however, SRT3025 did not affect stem cell quiescence, suggesting distinct mechanisms of action. Conditional deletion of Sirt1 in hematopoietic cells did not abrogate the beneficial effects of SRT3025, indicating that the drug did not act by directly stimulating Sirt1 in stem cells, but must be acting indirectly via extra-hematopoietic effects. RNA-Seq transcriptome analysis revealed the down-regulation of Egr1-p21 expression, providing a potential mechanism for improved hematopoiesis. Overall, our data indicate that SRT3025 or related compounds may be beneficial in Fanconi anemia and other bone marrow failure syndromes.

    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.

    2008-03-01

    Full Text Available Background: Immune deficiency is one of the major causes of morbidity and mortality in the modern world. Primary immunodeficiency comprises a wide range of disorders that mainly manifest in early childhood as devastating infections with opportunistic organisms. Thymic aplasia is found on autopsy of some patients afflicted with immune deficiency disorders, such as DiGeorge syndrome and severe combined immunodeficiency (SCID. After a thorough search of the literature, we found little information on the cellular characteristics of these thymuses. Our study aims to elucidate role of apoptosis in the pathogenesis of thymic aplasia and compare various lymphocytic and epithelial markers in normal and aplastic thymuses. Methods: We selected 12 subjects who died of severe infections with aplastic thymus found on autopsy, and 11 control subjects who died of unrelated causes, such as congenital heart disease. The presence of several markers, including Bcl2, P53, lymphocytic markers, and CD68, was examined using immunohistochemical methods on paraffin-embedded thymus sections. Positively-stained cells were counted per 1000 cells and the results stated as percentage of positive cells.                        Results: The mean age of the control group was between 7 days to 18 months (mean: 4.5 months. Parental consanguinity was present in 45.5% and 9.1% of the control and case groups, respectively; however, this was not statistically significant. We found significantly lower expression of Bcl2 in the case group (p value: 0.038. Furthermore, expression of CD68 was significantly higher in the case group. Epithelial markers were significantly higher in case subjects, although CD8 expression was higher in the control group. The presence of other markers was not significantly different between the two groups.Conclusions: Increase in apoptosis has a role in aplastic thymuses and prevention of apoptosis may halt this process. Also high CD68

    Aplastic anaemia (AA) can precede acute lymphoblastic leukaemia (ALL) in 2% of children but this is rarely reported to occur in adults. A 21-year-old male presented with bone marrow failure and bone marrow biopsy showed a profoundly hypocellular marrow. He recovered spontaneously but represented 2 months later when he was diagnosed with pre-B acute lymphoblastic leukaemia. Chromosomal examination revealed 46,XY,del(9)(q13q34). To the best of our knowledge this is the first case to be reported of aplasia preceding ALL with 9q minus as the sole chromosomal abnormality.

    再生障碍性贫血( aplastic anemia,AA)是一种以效应T细胞功能亢进导致造血组织损伤为特征的自身免疫性疾病.近年来研究发现,AA与Th17细胞数量增加及Treg细胞数量减少密切相关,且Th17和Treg细胞功能上相互拮抗.动物实验表明,IL-17抗体靶向治疗及Treg细胞回输治疗均可改善免疫介导的AA小鼠骨髓衰竭状态.本文就Th17/Treg细胞与AA关系最新研究进展作一综述,旨在进一步探讨AA发病机制,为临床治疗提供新思路.本综述讨论的主要问题有:Th1 7/Treg细胞一般生物学特性,Th17/Treg细胞平衡的调节及相关细胞因子,Th17/Treg细胞与再生障碍性贫血关系等.%Aplastic anemia (AA) is an autoimmune disease characterized by destruction of hematopoietic tissue resulting in hyperfunction of effector T-lymphocytes. Recent studies indicate that Thl7 and Treg cells are functionally antagonistic each other, and the increase of Thl7 cells and decrease of Treg cells are closely related with AA. In vivo experiments showed that both anti-IL-17 treatment and Treg cell infusion can protect against immune-mediated bone marrow failure in mouse with AA. This review summarizes the recent progress of study on imbalance of Thl7/ Treg cells in AA, so as to explore the pathogenesis of AA and provide approach to clinical treatment. The main problems that are discussed in this review include biological characteristics of Thl7/Treg cells, the regulation of Thl7/Treg cell balance and related cytokines, the relationship between Thl7/Treg cells and AA.

    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.

    Lower hemoglobin is associated with cognitive impairment and Alzheimer's disease (AD). Since brain iron homeostasis is perturbed in AD, we investigated whether this is peripherally reflected in the hematological and related blood chemistry values from the Australian Imaging Biomarker and Lifestyle (AIBL) study (a community-based, cross-sectional cohort comprising 768 healthy controls (HC), 133 participants with mild cognitive impairment (MCI) and 211 participants with AD). We found that individuals with AD had significantly lower hemoglobin, mean cell hemoglobin concentrations, packed cell volume and higher erythrocyte sedimentation rates (adjusted for age, gender, APOE-ɛ4 and site). In AD, plasma iron, transferrin, transferrin saturation and red cell folate levels exhibited a significant distortion of their customary relationship to hemoglobin levels. There was a strong association between anemia and AD (adjusted odds ratio (OR)=2.43, confidence interval (CI) (1.31, 4.54)). Moreover, AD emerged as a strong risk factor for anemia on step-down regression, even when controlling for all other available explanations for anemia (adjusted OR=3.41, 95% CI (1.68, 6.92)). These data indicated that AD is complicated by anemia, which may itself contribute to cognitive decline. PMID:24419041

    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.

    Hemolytic anemias consist of corpuscular, immun-hemolytic and toxic hemolytic anemias. Within the group of corpuscular hemolytic anemias, except for the paroxysmal nocturnal hemoglobinuria (PNH), all symptoms are caused by underlying heredetiary disorders within the red blood cell membran (hereditary spherocytosis), deficiencies of red cell enzymes (G6PDH- and pyrovatkinase deficiency) or disorders in the hemoglobin molecule (thalassaemia and sickle cell disease). Immune-hemolytic anemias are acquired hemolytic anemias and hemolysis is caused by auto- or allo-antibodies which are directed against red blood cell antigens. They are classified as warm, cold, mixed type or drug-induced hemolytic anemia. Therapy consists of glucocorticoids and other immunsuppressive drugs. Pernicious anemia is the most important vitamin B12 deficiency disorder. Diagnosis relies on cobalamin deficiency and antibodies to intrinsic factor. The management should focus on a possibly life-long replacement treatment with cobalamin. PMID:26306021

    2007-11-01

    An increasing understanding of the process of erythropoiesis raises some interesting questions about the pathophysiology, diagnosis and treatment of anemia and erythrocytosis. The mechanisms underlying the development of many of the erythrocytoses, previously characterised as idiopathic, have been elucidated leading to an increased understanding of oxygen homeostasis. Characterisation of anemia and erythrocytosis in relation to serum erythropoietin levels can be a useful addition to clinical diagnostic criteria and provide a rationale for treatment with erythropoiesis stimulating agents (ESAs). Recombinant human erythropoietin as well as other ESAs are now widely used to treat anemias associated with a range of conditions, including chronic kidney disease, chronic inflammatory disorders and cancer. There is also heightened awareness of the potential abuse of ESAs to boost athletic performance in competitive sport. The discovery of erythropoietin receptors outside of the erythropoietic compartment may herald future applications for ESAs in the management of neurological and cardiac diseases. The current controversy concerning optimal hemoglobin levels in chronic kidney disease patients treated with ESAs and the potential negative clinical outcomes of ESA treatment in cancer reinforces the need for cautious evaluation of the pleiotropic effects of ESAs in non-erythroid tissues.

Ten patients had abnormal liver function. The CT Hounsfield units in the liver increased significantly in eleven patients, and were proportional to their serum ferritin levels. Skin pigmentation, liver dysfunction, and endocrine dysfunction were observed in nine patients with serum ferritin >3,500 ng/mL, eight of whom have since died. Interestingly, serum ferritin levels did not decrease significantly in nine transfusion-dependent patients who had received 15–60 days of iron-chelating therapy.Conclusion: Transfusion-dependent patients may progress to secondary iron overload with organ impairment, which may be fatal in those who are heavily iron-overloaded. The CT Hounsfield unit is a sensitive indicator of iron overload in the liver. Iron chelation therapy should be initiated when serum ferritin is >1,000 ng/mL and continued until it is <1,000 ng/mL in transfusional iron-overloaded patients.Keywords: anemia, aplastic, iron overload, myelodysplastic syndromes

    Diamond-Blackfan anemia is a rare, inherited disease that characteristically presents as a chronic, normochromic macrocytosis due to red cell lineage bone marrow failure. Although studies are elaborating on the genetic basis for its associated comorbidities, little has been published comparing this anemia to other chronic anemias that have similar laboratory results in children. This article offers a global perspective of the disease and compares it with anemia due to vitamin B12 and folate deficiency in children.

    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. PMID:26818422

    2007-01-01

    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. .

Methods To measure and analyze the eric status of bone marrow, diagnosis according to morphology and biopsy of bone marrow, and etiology of anemia(IDA) in 218 cases of anemia in the aged. Results In these 218 cases male patients were slightly more than female patients. Median age was 68.9. Ratio of cases with macrocytic anemia was the highest(42.66%), ratio of cases with active erythropoietic status was 82. 35%. Iron deficiency anemia was the most common anemia in the elderly(39. 44%), and megaloblastic anemia and myelodysplastic syndrome (MDS) were also frequent. Insufficient ingestion was the most common cause of IDA(25.66 %),and tumors,digestive ulcers and postgastrectomy were also the common causes. MDS,megaloblastic anemia and chronic aplastic anemia(CAA) were the common anemia in geriatric population with pancytopenia. Conclusions Geriatric population is the fragile group. Ratio of cases with anemia due to IDA and malnutrition is high in cases of anemia in the elderly.

    Anemia is a common problem in the neonatal period. Presenting symptoms may suggest numerous possible diagnoses ranging from anemia seen as a normal part of development to anemia due to critical pathology. An illustrative case is presented to highlight the appropriate evaluation of the neonate with significant anemia. Several important features of the evaluation of neonatal anemia are highlighted. The constellation of signs and symptoms that occur in conjunction with the anemia are critical for the evaluation. The evaluation should be performed in a step-wise process that starts by eliminating common causes of anemia. Manual review of the peripheral blood smear with a hematologist can be helpful.

    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

    Anemia and thrombocytopenia are frequent clinical manifestations of myelofibrosis as well as important prognostic factors of the disease. Concerning the treatment of anemia, the first step should be the correction of reversible contributing factors, such as possible iron, folate and vitamin B12 deficiency. Then, treatment options include erythropoiesis stimulating agents, androgens, immunomodulating drugs, corticosteroids, and splenectomy. Anemia responses may also be observed in some patients treated with JAK inhibitors. However, most patients eventually fail to such therapies and become transfusion dependent. Some of the aforementioned therapies can also improve thrombocytopenia, but the responses are usually observed in patients with moderate platelet count decrease. Allogeneic hematopoietic stem cell transplantation, the only curative treatment of myelofibrosis, can be an alternative for selected patients with cytopenias who are refractory to conventional therapies. However, for the majority of patients, the management of anemia and severe thrombocytopenia remains an unmet need. PMID:26891375

    Following acute arsenic ingestion, a 35 year old woman experienced multiple organ failure, including renal and respiratory insufficiency, toxic hepatitis, peripheral neuropathy, and encephalopathy. In addition, she developed an anemia; the bone marrow showed a striking dyserythropoiesis with megaloblastic features. Her recovery was heralded by normalization of the bone marrow morphology, followed by improvement in all other organ dysfunction except for the peripheral neuropathy. Arsenic poisoning is a cause of megaloblastic anemia; early hematologic recovery suggests favorable prognosis.

    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.

  6. Iron deficiency anemia in celiac disease.

    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.

    Utilizing longitudinal data from the nationally-representative Mexico Family Life Survey, this study assesses the association between family structure and iron-deficient anemia among children ages 3-12 in Mexico. The longitudinal models (n = 4649), which control for baseline anemia status and allow for consideration of family structure transitions, suggest that children living in stable-cohabiting and single-mother families and those who have recently experienced a parental union dissolution have higher odds of anemia than those in stable-married, father-present family structures. Interaction effects indicate that unmarried family contexts have stronger associations with anemia in older children (over age five); and, that the negative effects of parental union dissolution are exacerbated in poorer households. Resident maternal grandparents have a significant beneficial effect on child anemia independent of parental family structure. These results highlight the importance of family structure for child micronutrient deficiencies and suggest that understanding social processes within households may be critical to preventing child anemia in Mexico.

    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.

    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.

  10. Correlative study on anemia and radiotherapy effects in nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    Objective: To study the effect of oxygen-carrying ability of blood efficacy of radiotherapy for patients with nasopharyngeal carcinoma. Methods: Altogether 161 cases of patients with nasopharyngeal carcinoma were classified according to severity of anemia, and Hb, RBC, MCH, HCT, MCV, MCHC and RDW were tested before, during and after radiotherapy. The patients were followed-up for up to 5 years, the relationship and mechanism among anemia, radiotherapy effects and survival rate was discussed. Results: The survival rate between anemia group and non-anemia group was different significantly (P<0.05). Anemia before radiotherapy, anemia appearance or anemia deterioration during radiotherapy were sensitive factors affecting radiotherapy results. The anemia more severe, the radiotherapy worse. Conclusion: Anemia-hypohemoglobinemia leads to decrease of oxygen-carrying capacity of blood, resulting in oxygen deficiency of tumor cells and their radiotherapy resistance. Therefore this method is worthy of further studies

    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.

    2007-01-01

    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 Over the past few years complete blood count (CBC by the automated hematology analyzers and microscopic examination of peripheral smear have complemented each other to provide a comprehensive report on patients’ blood sample. Numerous classifications for anemia have been established and the important parameters involved in the classifications are Hb, HCT, MCV, RDW, MCH, MCHC, reticulocytes and IRF. Many of these values are obtained only by automated heamatology analyzers. One histogram graph is worth 1000 numbers. A large collection of data, displayed as a visual image, can convey information with far more impact than the numbers alone. In hematology, these data take on several forms, one of which is the RBC histogram. Therefore a study of variation in RBC histograms in various anemias. Many times it is seen that histogram patterns show varying features when a simultaneous peripheral smear is reported. It is also seen that there are many limitations when manual peripheral smears reporting is done for example: peripheral smear reports are subjective, labor intensive and statistically unreliable. However microscopic peripheral smear examination also has their advantages. This study intends to create a guide to laboratory personnel and clinicians with sufficient accuracy to presumptively diagnose morphological classes of anemia directly from the automated hematology cell counter forms and correlate with morphological features of peripheral smear examination. OBJECTIVE: 1. The objective of the study is to know the utility and advantage of red cell histograms. 2. To study the automated histogram patterns along with morphological features noticed on peripheral smear examination. SOURCE OF DATA: All anemic patients from Central Diagnostic Laboratory of A.J.IMS. METHOD OF COLLECTION OF DATA: A total of about 100 patients were included in the study. Complete blood count including HB, TC, DC, Platelet count hematocrit value, RBC indices was obtained

    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.

    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.

    The aim of this study was to establish the prevalence of anemia in stable pediatric renal transplant recipients and to examine the association of anemia with renal function, immunosuppressants, angiotensin converting enzyme inhibitors, and growth, as well as iron, vitamin B(12), and folate stores. This is a cross-sectional study of the 50 renal transplant recipients currently followed at our center. Patient data were collected regarding hematological parameters, growth, medications, renal function, underlying renal disease, delayed graft function, episodes of rejection, and iron or erythropoietin therapy post transplantation. The mean hemoglobin level (Hb) was 110 g/l and the overall prevalence of anemia was 60%, including 30% who were severely anemic (Hb<100 g/l). There was a high rate of iron deficiency (34%) and serum iron was the parameter of iron metabolism most closely associated with anemia. Hb in patients with low serum iron was 90.7 g/l versus 114.4 g/l in those with normal serum iron ( P<0.01). Both univariate and multiple linear regression determined tacrolimus dose and creatinine clearance to be significant factors associated with anemia. Tacrolimus dose correlated with a 10 g/l reduction in Hb for every increase of tacrolimus dose of 0.054 mg/kg per day ( P=0.001). The dose of mycophenolate was positively correlated with Hb, but this was likely to be confounded by our practice of dose reduction in the setting of anemia. Angiotensin converting enzyme inhibitor use was not associated with anemia. Severely anemic patients tended to be shorter, with a mean Z-score for height of -1.8 compared with -0.9 for those with normal Hb ( P=0.02). Anemia is a significant and common problem in pediatric renal transplant patients. Deteriorating renal function is an important cause, but other factors like iron deficiency and immunosuppression are involved. Definition of iron deficiency is difficult and serum iron may be a valuable indicator. Medication doses

    Megaloblastic anemia (MA) is a common disorder with varied manifestations. It generally results in mild to moderate splenomegaly which is due to sequestration of macrocytic erythrocytes in spleen. Massive splenomegaly is generally seen in infections, myeloproliferative diseases, neoplasms, storage disorders or hematological conditions; but is not heard of and has rarely been reported in MA. We discuss a case of massive splenomegaly who presented with symptomatic anemia and was found to have MA. He was extensive evaluated for all other causes of massive splenomegaly which was normal. Further, after a therapeutic trial of MA he showed a regression in spleen size confirming that the massive splenomegaly was attributable to MA. PMID:25825577

    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. PMID:26862056

    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.

    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. PMID:27542426

  13. Fanconi anemia proteins in telomere maintenance.

    Sarkar, Jaya; Liu, Yie

    2016-07-01

    Mammalian chromosome ends are protected by nucleoprotein structures called telomeres. Telomeres ensure genome stability by preventing chromosome termini from being recognized as DNA damage. Telomere length homeostasis is inevitable for telomere maintenance because critical shortening or over-lengthening of telomeres may lead to DNA damage response or delay in DNA replication, and hence genome instability. Due to their repetitive DNA sequence, unique architecture, bound shelterin proteins, and high propensity to form alternate/secondary DNA structures, telomeres are like common fragile sites and pose an inherent challenge to the progression of DNA replication, repair, and recombination apparatus. It is conceivable that longer the telomeres are, greater is the severity of such challenges. Recent studies have linked excessively long telomeres with increased tumorigenesis. Here we discuss telomere abnormalities in a rare recessive chromosomal instability disorder called Fanconi Anemia and the role of the Fanconi Anemia pathway in telomere biology. Reports suggest that Fanconi Anemia proteins play a role in maintaining long telomeres, including processing telomeric joint molecule intermediates. We speculate that ablation of the Fanconi Anemia pathway would lead to inadequate aberrant structural barrier resolution at excessively long telomeres, thereby causing replicative burden on the cell.

    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.

    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.

    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 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.

    Full Text Available Anemia during childhood impairs physical growth, cognitive development and school performance. Identifying the causes of anemia in specific contexts can help efforts to prevent negative consequences of anemia among children. The objective of this study was to assess prevalence and identify correlates of anemia among school children in Eastern Ethiopia.A cross sectional study was conducted from January 2012 to February 2012 in Kersa, Eastern Ethiopia. The study included randomly selected primary school students. Hemoglobin concentration was measured using a Hemocue haemoglobinometer. A child was identified as anemic if the hemoglobin concentration was <11.5 g/dl for children (5-11 yrs and < 12 g/dl for child older than 12 years age. Poisson regression model with robust variance was used to calculate prevalence ratios.The overall prevalence of anemia was 27.1% (95% CI: 24.98, 29.14: 13.8% had mild, 10.8% moderate, and 2.3% severe anemia. Children with in the age group of 5-9 years (APR, 1.083; 95% CI, 1.044-1.124 were at higher risk for anemia. Paternal education (Illiterate, 1.109; 1.044-1.178 was positively associated with anemia. Children who had irregular legume consumption (APR, 1.069; 95% CI, 1.022-1.118 were at higher risk for anemia.About a quarter of school children suffer from anemia and their educational potential is likely to be affected especially for those with moderate and severe anemia. Child age, irregular legume consumption, and low paternal schooling were associated with anemia. Intervention programmes aimed to reduce anemia among school children are crucial to ensure proper growth and development of children.

  2. 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.

    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.

    Many validated instruments exist for determining the impact of chemotherapy-induced anemia and related fatigue on patient quality of life, but few studies analyze how healthcare providers actually discuss these subjects with patients. The authors share their study results on patterns of communication between participating patients and their physicians and allied health professionals. Letters of invitation were mailed to over 1,000 community-based oncologists, 15 of whom met the criteria and agreed to participate in this study on a first-enrolled basis until sufficient participation was ensured. In total, 36 of their patients were audio- and/or video-recorded during their regularly scheduled visits. Post-visit interviews were conducted separately with patients and participating healthcare professionals. Interviews were transcribed and analyzed using sociolinguistic techniques. Although 52% of visit time was spent discussing side effects and symptoms, most discussions of anemia and fatigue lacked specificity necessary to determine their true impact on patients' lives. Physician inquiries regarding fatigue also tended to be too brief to elicit patients' chief concerns. Vocabulary used to discuss anemia and related fatigue was variable and imprecise, and no fatigue assessment instrument was used or referenced in any visit. Community-based oncologists are encouraged to modify their vocabulary and consider incorporating a validated fatigue instrument, either within or before the consultation, to improve the quality of such communication.

    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.

  18. [Anemia treatment in peritoneal dialysis patients].

    Anemia is highly prevalent among chronic kidney disease (CKD) patients and patients receiving renal replacement therapy. In this paper we will outline the prevention and treatment of anemia in patients treated with peritoneal dialysis (PD). PD patients are less anemic and more sensitive to erythropoesis-stimulating agent (ESA) than their hemodialysis (HD) counterparts and, in general, dosages required for achieving similar hemoglobin levels to those achieved in HD patients are remarkably less. Before starting with ESA treatment we have to evaluate the degree of anemia and excluded other causes which are not connected with CKD and method of treatment. Patient's compliance is crucial for a successful therapy and it can be improved by decreasing frequency of administration of ESA. Since ESAare expensive, "cost-effectivnes" studies represent an important factor in choosing a distinct drug. Subcutaneous administration provides better long-term utilization of ESA in comparison to intravenous administration and is therefore preferred in PD patients. Intraperitoneal administration is not recommended due to poor bioavailability. In some patients we can observe the reduced response to ESA therapy. The definition of reduced response is generally regarded as a failure to achieve target hemoglobin concentration of >11 g/dL. Identification of underlying cause is not always easy but every attempt should be made to investigate every patient with resistance to therapy because some causes are easily corrected. Since 2005 particular ESA drugs have been approved by Croatian Institute for Health Insurance and registered for use in Croatia. For PD patients the ESAcan be prescribed by general practitioner. The list of available drugs is available in the official government newspaper Nardone novine No.27, March 2nd, 2009. PMID:20232548

  19. Iron, anemia and hepcidin in malaria

    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.

    Full Text Available Objective: To determine the prevalence of anemia and nutritional anemia in primary school children in the city of Aydın. Materials and Methods: In Aydın, the central town of Aydın province, a total of 496 students (56% were female were enrolled into the study by using stratified random sampling method. The students were from the primary schools located in socio-economically low, medium, and high areas of primary health care centers. The avarage age of the students was 10.2±2 years. Statistical analysis was performed using the Kolmogorov-Smirnov test, Student’s t-test, Mann-Whitney U-test and Chi-Square test. Results: The prevalence of anemia, iron-deficiency (ID, iron-deficiency anemia (IDA, vitamin B12 deficiency and vitamin B12 deficiency anemia was 15.7%, 38.7%, 8.3%, 9.1%, 0.8%, respectively. No folic acid deficiency was detected. Among the anemias, 42% of them were microcytic, 58% of them were normocytic and the 45.5% of the microcytic anemias were IDA. Among the females, the rate of ID was 45.1% and the rate of IDA was 11.6%, while in boys the same rates were 30.6% and 4.1%, respectively (p<0.05. Microcytosis was present in 36.5% of subjects with IDA. The Mentzer index was <13 in 13.3% of subjects with microcytic anemia and IDA, and in 77.7% of children with microcytic anemia and no IDA (p<0.001. Regarding socio-demographic characteristics of children; the only statistically significant difference was in the parameters of mother education and anemia. Conclusion: The prevalence of anemia represents a minor public health problem according to the World Health Organization criteria among the primary school students in the central town of Aydın province. Exploration of the reason of anemia among pre-school children, proper treatment of nutritional anemia cases with adequate duration and dose, dietary organizations and proper follow-up will lower the incidence of anemia and nutritional anemia among primary school children.

    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.

    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 Introduction: Nutritional anemia is one of India's major public health problems. Adolescence is a vulnerable period in the human life cycle for the development of nutritional anemia. Anemia in adolescent girls contributes to maternal and foetal mortality and morbidity in future. Most of the health care services in India are for mother and child group. Objectives: To estimate prevalence of anemia among adolescent girls in an urban slum and to study socio-demographic and menstrual factors associated with it. Material and methods: A cross sectional community based study was conducted among 272 adolescent girls in an urban slum area under Urban Health Training centre, department of Community Medicine, NKP Salve Institute of Medical science, Nagpur from June 2009 to February 2010. Out of five areas one area was selected by simple random sampling. Information regarding socio-demographic and menstrual factors was recorded in pre-designed, pre -tested proforma. Hemoglobin estimation was done by Sahli’s haemoglobinometer. Data was analyzed by mean, standard deviation and chi square test. Results: Prevalence of anemia was found to be very high (90.1% among adolescent girls. Majority of the girls were having mild or moderate anemia (88.6%. A significant association was found between adolescent girl’s education, mother’s occupation and anemia. No association was found between menstrual factors and anemia. Conclusions-Nutrition education along with nutritional supplementation and iron folic acid tablets should be provided to all girls.

    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.

    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.

    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

    Hookworm infections as well as other intestinal nematodiases are endemic in China. In this case, a 70-year-old male showed symptoms of chest tightness, shortness of breath, and both lower extremities edema. The diagnostic result was chronic renal insufficiency, chronic kidney disease (5th stage), and renal anemia at first. Then, he received treatment with traditional drugs. However, this treatment did not help to alleviate the symptoms of the patient significantly. The results of gastroendoscopy showed hookworms in the duodenum, also confirmed by pathology examination. Anemia was markedly ameliorated after eliminating the parasites. The results mentioned above suggested that ancylostomiasis was the leading causes of anemia in this patient, and the etiology of anemia in uremic patients should be systematically considered. Especially when anemia could not be cured by regular treatments, rare diseases should be investigated. PMID:27417086

    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.

  1. Microfluidic approach of Sickled Cell Anemia

    Science.gov (United States)

    Abkarian, Manouk; Loiseau, Etienne; Massiera, Gladys

    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.

    2013-01-01

    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 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.

    Full Text Available A 62-year-old man with a history of mechanical aortic valve insertion and ascending aorta replacement in 1997 presented to his family doctor in August 2004 with a two-week history of melena after recently returning from a six-month vacation in Mexico. The patient had no other abdominal complaints. He took warfarin but did not take nonsteroidal anti-inflammatory agents, acetylsalicylic acid or alcohol. The patient had no history of liver or peptic ulcer disease. He had lost 7 kg over the past month, but did not complain of fever or night sweats. On physical examination, vital signs were normal, the second heart sound was mechanical, and there were no abnormal findings. Laboratory investigations showed a borderline microcytic anemia (hemoglobin 76 g/L; mean corpuscular volume 79 fL; mean corpuscular hemoglobin concentration 323 g/L, a therapeutic international normalized ratio (2.6 and an elevated creatinine level (112 µmol/L. His stool was positive for occult blood, although the ferritin level was high (623 µg/L. Other routine blood work was normal. The patient was admitted to hospital for investigation of the anemia.

    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 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

    Pernicious anemia (also known as Biermer disease or anemia, Addison or Addisonian anemia, and Addison-Biermer anemia) is an autoimmune atrophic gastritis responsible for vitamin B12 malabsorption due to a deficiency of intrinsic factor. We report eight cases of pernicious anemia in Burkina Faso, collected over a 44-month period. The three criteria for diagnosis of pernicious anemia were: vitamin B12 deficiency, gastric disease (gastric histology) with presence of anti-intrinsic factor, and/or anti-gastric parietal cell antibodies in serum. All patients had anemia, with a mean hemoglobin level of 8.75 g/100 mL. The average mean corpuscular volume (MCV) was 122.1 fL the average mean corpuscular hemoglobin (MCH) 39.3 pg, the mean reticulocyte count 12.069 10(9)/L reticulocytes, and the mean rate of megaloblast marrow cells 17.2%. The serum vitamin B12 level ranged from 35 to 71 pmol/L. Antibodies against intrinsic factor were found in all eight patients. All ABO blood groups were present with a predominance (4 cases) of group O. Endoscopy found a normal fundic mucosa in three patients. Histology showed gastric atrophy and intestinal metaplasia for six patients (85.7%). Under B12 vitamin therapy, the course was favorable in all patients; seven patients also had 10 days of iron therapy. We recommend a gastric biopsy even in the absence of macroscopic gastric lesions on the upper gastrointestinal endoscopy. PMID:25787024

    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.

    Anemia is a global public health problem. It has serious short- and long-term consequences during pregnancy and beyond. The anemic condition is often worsened by the presence of other chronic diseases such as malaria, tuberculosis, HIV, and diabetes. Untreated anemia also leads to increased morbidity and mortality from these chronic conditions as well. It is surprising that despite these chronic conditions (such as malaria, tuberculosis, and HIV) often being preventable, they still pose a real threat to public health. This article aims to review the current understanding of the pathophysiology, risks, prevention, and treatment of anemia in the light of these chronic conditions. PMID:22099433

    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.

    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. .

    Proper management of sickle cell anemia (SCA) begins with establishing the correct diagnosis early in life, ideally during the newborn period. The identification of affected infants by neonatal screening programs allows early initiation of prophylactic penicillin and pneumococcal immunizations, which help prevent overwhelming sepsis. Ongoing education of families promotes the early recognition of disease-released complications, which allows prompt and appropriate medical evaluation and therapeutic intervention. Periodic evaluation by trained specialists helps provide comprehensive care, including transcranial Doppler examinations to identify children at risk for primary stroke, plus assessments for other parenchymal organ damage as patients become teens and adults. Treatment approaches that previously highlighted acute vaso-occlusive events are now evolving to the concept of preventive therapy. Liberalized use of blood transfusions and early consideration of hydroxyurea treatment represent a new treatment paradigm for SCA management. PMID:23709685

    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.

    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

    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.

    Twenty cases of Dyphillobothrium pacificum (fish tapeworm) infections were prospectively studied to determine whether this tapeworm is associated with megaloblastic anemia, as commonly reported for D. latum infections. The most frequent symptoms were fatigue and mild abdominal pain, which were identified in approximately 66.6% of the 18 patients interviewed. Fourteen patients received treatment with niclosamide and all were cured. The other six patients spontaneously eliminated the tapeworms. One patient, who also had chronic diabetes and gastric atrophy, had low vitamin B12 levels and megaloblastic anemia. In all other patients, including three other patients with anemia, baseline vitamin B12 levels were in the reference range and did not significantly change when re-assessed three months later. Unlike D. latum, infection with D. pacificum is seldom associated with megaloblastic anemia or vitamin B12 deficit. PMID:22987655

    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

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.

    ABSTRACT Sickle cell anemia is a genetic disease that primarily affects the black population. This anemia is due to a homozygous state of the abnormal hemoglobin S. An alteration occurs on the DNA molecule involving the substitution of the amino acid valine for glutamic acid at the sixth position on the beta polypeptide chain. This biochemical variation on the DNA molecule creates a physiological change that causes sickle-shaped red blood cells to be produced. The sickle-shaped cells are the ...

    Full Text Available Cold agglutinin disease (CAD with autoimmune haemolytic anemia is characterized by the production of harmful cold autoantibodies associated with increased red cell destruction during exposure to cold. The treatment of CAD is very difficult and a great effort is required to obtain therapeutic success. Cyclophosphamide is a potent immunosuppressive agent which is widely used in all bone marrow transplantation conditioning regimens for patients with acquired severe aplastic anemia. In this report, we describe the case of a coronary artery disease patient with severe CAD, but without lymphoproliferative disease, in which general measures and immunosuppressive therapies were adopted, there by avoiding blood transfusions.A doença por aglutininas a frio (CAD cursando com anemia hemolítica auto-imune (AHAI é decorrente da produção de autoanticorpos que reagem muito bem a baixas temperaturas, dirigidos contra hemácias autólogas. A habilidade desses anticorpos em destruir as hemácias encontra-se diretamente relacionada à sua capacidade em fixar complemento durante a exposição do paciente a baixas temperaturas. A AHAI por anticorpos frios pode ser idiopática - ausência de doença de base - ou secundária, geralmente associada a desordens linfoproliferativas de células B ou determinados processos infecciosos. A hemólise é intravascular, através de aglutininas da classe IgM, com teste direto da antiglobulina humana positivo para complemento. O tratamento da CAD é difícil, exigindo um esforço contínuo, necessário para se obter sucesso terapêutico. A ciclofosfamida é um agente imunossupressor potente, amplamente utilizado em transplantes de medula óssea, particularmente nos portadores de anemia aplástica. Descrevemos o caso de um coronariopata portador de CAD severa, cuja exploração diagnóstica excluiu doença linfoproliferativa. Adotamos medidas gerais de suporte e terapia imunossupressora, coibindo o uso de hemotransfusões.

    Over 3 million people in the United States aged 65 years and older are anemic. This condition is associated with significant functional impairment and, perhaps, increased mortality. In March 2004, the American Society of Hematology (in conjunction with the National Institute of Aging) convened a "blue ribbon" panel of twenty physicians who are experts on various aspects of this topic. This paper highlights important consensus concepts resulting from that meeting. In particular, four areas of thought are shared. First, the epidemiology of anemia in the elderly is reviewed, including its definition, its expression in different racial groups, and its wide-ranging manifestations. Second, the pathophysiology of anemia in the elderly is reviewed as pertains to three general etiological categories (nutritional, chronic diseases, and so-called "unexplained" anemias). Particular emphasis is given to pathophysiologic mechanisms of anemia that are potentially unique to this age group. Third, a practical approach to the diagnosis and management of anemia for this patient population for the practicing hematologist is provided. Finally, the public health implications of anemia in the elderly for key stakeholder constituencies will be discussed in the oral presentation. PMID:16304431

    Full Text Available Anemia is one of the most frequent complications and/or extraintestinal manifestations of inflammatory bowel disease (IBD. Iron deficiency is the most important cause of anemia in Crohn’s disease and ulcerative colitis patients. Iron deficiency even without anemia may impact the quality of life of our IBD patients. In the last ten years the understanding of the pathophysiology of iron deficiency anemia and anemia of chronic diseases has increased, new diagnostic tools have been developed and new therapeutic strategies have been discussed. Hepcidin has been identified to be a central regulator of iron absorption from the intestine and of iron plasma levels. Hepcidin is regulated by iron deficiency but also as an acute phase protein by pro-inflammatory mediators such as interleukin-6. Innovative diagnostic tools with respect to iron metabolism have not been introduced in clinical routine or are not available for routine diagnostics. As iron substitution therapy is easy these days with a preference for intravenous substitution the impact of differential diagnosis of anemia in IBD patients is underestimated.

    Full Text Available Abstract Objective: To identify the prevalence and factors associated with anemia in children attending Municipal Early Childhood Education Day Care Center (Centros Municipais de Educação Infantil [CMEI] nurseries in Colombo-PR. Methods: Analytical, cross-sectional study with a representative sample of 334 children obtained by stratified cluster sampling, with random selection of 26 nurseries. Data collection was conducted through interviews with parents, assessment of iron intake by direct food weighing, and hemoglobin measurement using the finger-stick test. Bivariate association tests were performed followed by multiple logistic regression adjustment. Results: The prevalence of anemia was 34.7%. Factors associated with anemia were: maternal age younger than 28 years old (p = 0.03, male children (p = 0.02, children younger than 24 months (p = 0.01, and children who did not consume iron food sources (meat + beans + dark green leafy vegetables (p = 0.02. There was no association between anemia and iron food intake in CMEI. However, iron intake was well below the recommended levels according to the National Education Development Fund resolution, higher prevalence of anemia was observed in children whose intake of iron, heme iron, and nonheme iron was below the median. Conclusions: In terms of public health, the prevalence of anemia is characterized as a moderate problem in the studied population and demonstrates the need for coordination of interdisciplinary actions for its reduction in CMEI nurseries.

    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.

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

    Full Text Available Iron deficiency anemia (IDA and anemia of chronic disease are the most commonly confused anemias. 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.

    2013-03-01

    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

CONCLUSÕES: o CHE isolado foi uma manifestação grave em pacientes internados com LESJ, habitualmente associado a uma doença ativa e sistêmica.OBJECTIVE: to evaluate the hematological involvement (HI in hospitalized patients with juvenile systemic lupus erythematosus (JSLE. METHODS: from 1994 to 2005, 195 admissions occurred in 77 JSLE patients (American College of Rheumatology criteria and were followed by the Pediatric Rheumatology Unit of the Instituto da Criança - University of São Paulo. These admissions were evaluated according to the presence of HI at onset or during the evolution of the disease: autoimmune hemolytic anemia (AHA or thrombocytopenic purpura. All patients performed at least two complete blood counts. AHA was defined by a fall in hemoglobin levels (beyond 2 g/dl, reticulocytosis, increase in lactate dehydrogenase (LDH and indirect bilirubin levels, and a positive Coombs test. The hematologic manifestations associated with infection, neoplasia and aplastic anemia were excluded. RESULTS: HI occurred in 14 patients (18.9%, with 15 admissions. Among these patients, 11 were female, 7 had trombocytopenic purpura, 5 AHA and 2 Evans syndrome. HI as onset and single manifestation of JSLE was observed in three patients. All the patients with trombocytopenic purpura presented cutaneous bleeding (petechia and/or ecchymosis. All had disease activity and simultaneously presented other manifestations of JSLE, particularly nephritis and vasculitis. Initially, all patients received pulsetherapy with methylprednisolone and prednisone later. In three patients the treatment aimed predominantly the control of hematologic manifestations, with intravenous gammaglobulin. The most used immunossupressive therapies were intravenous cyclophosphamide, cyclosporine and azathioprine. One patient died of central nervous system bleeding. No patient needed splenectomy.

    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. PMID:26935626

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

    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.

    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.

    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 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.

  5. CORD SERUM FERRITIN AS BIOCHEMICAL MARKER IN IRON DEFICIENCY ANEMIA

    2014-07-01

    Full Text Available Iron deficiency anemia is by far the most frequent type of anemia seen in pregnancy, accounting for 90% or more of all cases. Iron deficiency anemia has adverse consequences on infant development. Therefore maternal anemia should be prevented and treated. Serum ferritin is the single best non-invasive test and is a very useful and reliable index of iron stores especially during pregnancy, with low levels indicating iron deficiency. While infants born to anemic mother are themselves not anemic, they do not suffer from low iron stores. The main aim of the study is to establish cord serum ferritin as a biochemical marker in iron deficiency anemia. The specific objectives of this study is to estimate cord and maternal serum ferritin in the last trimester of pregnancy and to correlate it with hematological parameters. Cord serum ferritin levels were normal in the patients under study, even when the maternal serum ferritin levels were decreased. The mean level of cord serum ferritin was 134.06ng/ml and maternal serum ferritin was 41.65ng/ml and was statistically significant. The hematological parameters like hemoglobin, hematocrit, MCV and MCHC were also decreased in the patients with low serum ferritin and were found to be statistically significant. Hence estimation of cord serum ferritin can be used as a biochemical marker to assess iron deficiency in the early stages itself and thereby neurodevelopmental complications in children can be prevented.

  6. Sideroblastic anemia in 7 dogs (1996-2002).

    Weiss, Douglas J

    2005-01-01

    Sideroblastic anemia is an anemic condition characterized by chronic hypochromic anemia and the presence of large iron deposits in erythroid cells. Seven dogs with sideroblastic anemia were evaluated retrospectively. Historical, clinical, and clinicopathologic findings were reviewed to determine whether the condition was idiopathic or associated with disease conditions or drug or toxin exposure. Associated diseases were identified in 6 affected dogs and included acute hepatitis, pancreatitis, acute hepatitis and pancreatitis, inflammatory disease, glomerulonephritis, and myelofibrosis. None of the dogs had a history of recent exposure to drugs or toxins. One dog had no evidence of associated disease. Regardless of the associated disease condition, sideroblastic anemia was characterized by moderate to severe nonregenerative and frequently hypochromic anemia with prominent dysplastic features in bone marrow that were most prominent in the erythroid series. Survival varied from days to years. Identification of large numbers of siderocytes or sideroblasts in blood or bone marrow is inconsistent with a diagnosis of iron deficiency and should prompt a search for inflammatory disease conditions, including hepatitis, pancreatitis, and glomerulonephritis.

    Full Text Available Introduction. One of the characteristic signs of uremic syndrome is anemia. One of major factors that affects on severity of anemia in ESRD is underlying diseas. The porpuse of this study is to compaire anemia between diabetic and non diabetic ESRD patients. Methods. In a case control study we compared the mean valuse of Hb, Het, MCV, MCH, MCHC, BUN, Cr and duration of dialysis between diabetic and nondiabetic patients on chronic hemodialyis. some variables (such as age, sex, use of erythropoietin, nonderolone decaonats, folic acid, ferrous sulfate, transfusion and blood loss in recent three months and acquired kidney cysts were matched between cases and controls. Results. Means of Hb were 9±1.3 and 8 ± 1.7 in diabetic and non diabetic patients (P<0.05. Mean corposcular volume in diabetic patients (91±3.1 fl was more higher than non diabetic ones (87.1 ± 8.9 (P < 0.05. Other indices had no differences between two groups (P > 0.05. Discussion. Severity of anemia in patients with diabetic nephropathy is milder that other patients with ESRD. So, Anemia as an indicator of chronocity of renal disease in diabetics is missleading.

    Full Text Available Malaria is a vector born infectious disease that represents an enormous health and socio-economic burden worldwide, particularly for communities from tropical and subtropical regions, where more than 500 million of clinical cases are recorded every year. Human malaria is produced by four different Plamodium species, from which P. falciparum and P. vivax are the prevalent species. The clinical manifestations of malaria are very pleomorphic and could range from febrile episodes of short duration if an effective and opportune treatment is installed, to severe systemic complications and death. One of the most frequent and severe, malaria complication is anemia that represents one of the major obstacles for the development of endemic areas, due to its negative impact for children performance at school as well as for adult productivity. The physiopathology of anemia is poorly understood, but it is accepted that the overall anemia burden is produced through multiple mechanisms that include the destruction of both infected and non-infected red blood cells, erythrophagocytoses and a potential arrest of erythropoyesis. Anemia contributes significantly to the severity of malaria and to its mortality. Here we review the current understanding of the mechanisms involved in the production of malaria related anemia, its treatment and the potential implications of malaria vaccines in the prevention of this complication.

    Progress is reported on studies on hereditary anemias of mice. 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, each of 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.

    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. PMID:24678166

    Four macrocytic anemias, four hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, an ..cap alpha..-thalassemia, and a new target-cell anemia are under investigation in mice. 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 the 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.

    Chronic anemia develops over a course of weeks to months and is usually mild to moderate in nature. It is important to understand the etiology of the reduced number of circulating red blood cells to treat the anemia appropriately. Diagnosis is dependent on patient history and laboratory findings, such as complete blood counts, iron studies, a peripheral smear, and occasionally, a bone marrow biopsy. Treatment modalities frequently administered by infusion therapy nurses include treatment of the underlying chronic disease, replacement of deficiencies (iron, vitamin B12, folate, or erythropoietin), or transfusion of red blood cells. Infusion therapy nurses play a vital role in the assessment and delivery of medication therapy to patients with chronic anemia. PMID:26339940

    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 A 26-year-old previously healthy female presented with a 6-month history of anemia. The laboratory findings revealed hemolytic anemia and direct antiglobulin test was positive. 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.

    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.

    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. PMID:24605254

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

    Directory of Open Access Journals (Sweden)

    J Pedro Fernández-Murray

    2016-01-01

    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 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: Human immunodeficiency virus (HIV prevalence is high among rural dwellers and pregnant women. Aims: This study aims to determine the prevalence of HIV and anemia among pregnant women attending antenatal clinic in rural community of Okada, Edo State, Nigeria. 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.

    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.

    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.

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.

Iron deficiency anemia in children is a serious problem because it affects their growth and development. Early detection of IDA and subsequent treatment in childhood may prevent future health problems.Objective To assess the use of reticulocyte hemoglobin content (CHr to detect IDA in children aged 6-60 months.Methods We performed a cross-sectional study to measure the sensitivity and specificity of CHr compared to serum ferritin which is considered to be the gold standard for IDA diagnosis. The study was conducted from September 2011 to March 2013 in children aged 6-60 months who visited the Pediatric Outpatient Clinic, Sanglah Hospital, and Puskesmas II in West Denpasar. Data analysis was performed by 2x2 table. The results were assessed by area under the curve (AUC and receiver operating characteristic (ROC.Results Of 121 children underwent blood testing during the study period, 69 children were excluded because they did not have hypochromic microcytic anemia, leaving 52 subjects eligible for the study. The prevalence of IDA in this study was 31%. Reticulocyte hemoglobin content (CHr ≤ 23.1 pg had 88% (95%CI 71 to 100% sensitivity and 25% (95%CI 11 to 39% specificity.Conclusion Reticulocyte hemoglobin content < 23.1 pg may be a good predictor of IDA.

    1990-11-01

    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.

    2016-07-01

    Dysregulated iron homeostasis plays a central role in the development of anemia of chronic kidney disease (CKD) and is a major contributor toward resistance to treatment with erythropoiesis-stimulating agents. Understanding the underlying pathophysiology requires an in-depth understanding of normal iron physiology and regulation. Recent discoveries in the field of iron biology have greatly improved our understanding of the hormonal regulation of iron trafficking in human beings and how its alterations lead to the development of anemia of CKD. In addition, emerging evidence has suggested that iron homeostasis interacts with bone and mineral metabolism on multiple levels, opening up new avenues of investigation into the genesis of disordered iron metabolism in CKD. Building on recent advances in our understanding of normal iron physiology and abnormalities in iron homeostasis in CKD, this review characterizes how anemia related to disordered iron metabolism develops in the setting of CKD. In addition, this review explores our emerging recognition of the connections between iron homeostasis and mineral metabolism and their implications for the management of altered iron status and anemia of CKD.

Materials and Methods: A total of 30 patients with megaloblastic anemia (16 Male, 14 Female were included in the study. Cyanocobalamin was administered (1.000 µg/day intramuscularly until the reticulocyte crisis occurred to the normal range. The control group consisted of 30 healthy subjects (15 Male, 15 Female. Nitric oxide levels were measured before treatment and compared with the values obtained during peak reticulocyte count. Results: Plasma direct nitrite, total nitrite and nitrate levels were 24,86±3,87, 60.56±7,01 and 36,02±5,24 in before treatment versus 15,48±3,05, 38,92±6,44 and 22,77±6,04 μmol/dl in after treatment, respectively. Plasma direct nitrite, total nitrite and nitrate levels were significantly lower in after treatment compared with the before treatment (p<0.001. Conclusion: Nitric oxide levels are seen to increase in megaloblastic anemia. This study suggested that abnormalities in the nitric oxide levels in megaloblastic anemia are restored by vitamin B12 replacement therapy.

    Full Text Available Introduction In pernicious anemia besides the presence of megaloblasts in the bone marrow, changes in myeloid series were seen; being the most evident among the metamyelocyte. The aim of this study was to perform the quantification of metamyelocyte of the bone marrow in pernicious anemia. Material and methods Between 2000-2006 in the Clinic of Hematology-Niš, 68 patients with pernicious anemia were examined and 30 with dyspeptic syndrome (control group. The group of patients with pernicious anemia in relation to pathohistologic changes of gastric mucosa was divided into three sub-groups. Morphometrical analysis of metamyelocyte of the bone marrow was carried out by the application of the double netlike system (B100. The following parameters were used: relative surface, contour length, absolute surface of nucleus and cytoplasm, absolute contour nucleus and cytoplasm density, shaped nucleus and cytoplasmic factor and nuclear-cytoplasmatic ratio of meta- myelocytes. Results Relative surface, contour length, absolute surface and contour density of nucleus and cytoplasm of metamyelocytes increased simultaneously with the degree of atrophic gastritis. Shaped nucleus and cytoplasmic factor and nuclear-cytoplasmatic ratio of metamyelocytes decreased in all examined groups in relation to the control group. Conclusion Not only are bone marrow erythroid elements scoped with megaloblastic changes but the changes on the level of leukocyte cells as well. The result of this is the phenomena of giant metamyelocytes.

    Iron deficiency is the most common nutritional deficiency worldwide and an important public health problem especially in developing countries. Since the most important indicator of iron deficieny is anemia, the terms "iron deficiency" and "iron deficiency anemia" are often used interchangeably. However, iron deficiency may develop in the absence of anemia and the tissues may be affected from this condition. The most common causes of iron deficiency in children include insufficient intake together with rapid growth, low birth weight and gastrointestinal losses related to excessive intake of cow's milk. If insufficient intake can be excluded and there is insufficient response to oral iron treatment in patients with iron deficiency especially in older children, blood loss should be considered as the underlying cause. The main principles in management of iron deficiency anemia include investigation and elimination of the cause leading to iron deficiency, replacement of deficiency, improvement of nutrition and education of the patient and family. In this article, the practical approaches in the diagnosis and treatment of iron deficiency and the experience of our center have been reviewed. PMID:26078692

  18. Effect of 131I on the anemia of hyperthyroidism

    Data from the National Thyrotoxicosis Therapy Follow-Up Study (NTTFS) are presented here to document the existence of anemia in hyperthyroidism, a mild and reversible anemia that is simultaneously ameliorated with reversal of the hyperthyroid state. Among 20,600 women entered into the NTTF study with no previous history of hematological disorders, the prevalence of anemia was found to range from 10-15%, appearing to be higher in those selected for treatment with 131I when compared to those selected for surgery. An attempt is made to verify the recent hypothesis that thyroid hormone levels in the supraphysiologic range may suppress erythrogenesis. Two statistically significant regression models are consistent with a hypothesis of thyrotoxic bone marrow suppression. However, both associations are weak enough to suggest that some other physiologic improvement underlies the amelioration of anemia when hyperthyroidism is reversed. The degree of improvement in hematological status is similar for women in both treatment groups. Among 4464 women for whom serial hematological tests are obtained, over 3/4 of anemic patients are no longer anemic after an average 6.2 yr of follow-up. Clinicians are reassured that radioactive iodine exposure causes no further insult to the bone marrow, no matter what the cumulative dosage. The highly fractionated low dose bone marrow exposures to radiation account for the minimal hematological risks of 131I treatment.

    Dysregulated iron homeostasis plays a central role in the development of anemia of chronic kidney disease (CKD) and is a major contributor toward resistance to treatment with erythropoiesis-stimulating agents. Understanding the underlying pathophysiology requires an in-depth understanding of normal iron physiology and regulation. Recent discoveries in the field of iron biology have greatly improved our understanding of the hormonal regulation of iron trafficking in human beings and how its alterations lead to the development of anemia of CKD. In addition, emerging evidence has suggested that iron homeostasis interacts with bone and mineral metabolism on multiple levels, opening up new avenues of investigation into the genesis of disordered iron metabolism in CKD. Building on recent advances in our understanding of normal iron physiology and abnormalities in iron homeostasis in CKD, this review characterizes how anemia related to disordered iron metabolism develops in the setting of CKD. In addition, this review explores our emerging recognition of the connections between iron homeostasis and mineral metabolism and their implications for the management of altered iron status and anemia of CKD.

    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.

    Iron deficiency anemia (IDA) is associated with a number of pathological gastrointestinal conditions other than inflammatory bowel disease, and also with liver disorders. Different factors such as chronic bleeding, malabsorption and inflammation may contribute to IDA. Although patients with symptoms of anemia are frequently referred to gastroenterologists, the approach to diagnosis and selection of treatment as well as follow-up measures is not standardized and suboptimal. Iron deficiency, even without anemia, can substantially impact physical and cognitive function and reduce quality of life. Therefore, regular iron status assessment and awareness of the clinical consequences of impaired iron status are critical. While the range of options for treatment of IDA is increasing due to the availability of effective and well-tolerated parenteral iron preparations, a comprehensive overview of IDA and its therapy in patients with gastrointestinal conditions is currently lacking. Furthermore, definitions and assessment of iron status lack harmonization and there is a paucity of expert guidelines on this topic. This review summarizes current thinking concerning IDA as a common co-morbidity in specific gastrointestinal and liver disorders, and thus encourages a more unified treatment approach to anemia and iron deficiency, while offering gastroenterologists guidance on treatment options for IDA in everyday clinical practice.

    2015-01-01

    Nutritional iron deficiency anemia is the most common deficiency disorder, affecting more than two billion people worldwide. Oral iron supplementation is usually the first choice for the treatment of iron deficiency anemia, but in many conditions, oral iron is less than ideal mainly because of gastrointestinal adverse events and the long course needed to treat the disease and replenish body iron stores. Intravenous iron compounds consist of an iron oxyhydroxide core, which is surrounded by a carbohydrate shell made of polymers such as dextran, sucrose or gluconate. The first iron product for intravenous use was the high molecular weight iron dextran. However, dextran-containing intravenous iron preparations are associated with an elevated risk of anaphylactic reactions, which made physicians reluctant to use intravenous iron for the treatment of iron deficiency anemia over many years. Intravenous ferric carboxymaltose is a stable complex with the advantage of being non-dextran-containing and a very low immunogenic potential and therefore not predisposed to anaphylactic reactions. Its properties permit the administration of large doses (15 mg/kg; maximum of 1000 mg/infusion) in a single and rapid session (15-minute infusion) without the requirement of a test dose. The purpose of this review is to discuss some pertinent issues in relation to the history, pharmacology, administration, efficacy, and safety profile of ferric carboxymaltose in the treatment of patients with 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.

    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. Women are known to be more susceptible to anemia; however, no controlled study has yet assessed differences in the prevalence of anemia exclusively among women with higher education. The aim of the study was to establish the prevalence of anemia among women attending universities. The hemoglobin concentration of 140 women aged 18 to 45 years old from a private and a public university was measured. Anthropometric and socioeconomic data were also collected. The risk of developing anemia was almost threefold higher among the students attending the public university (OR: 2.71; p=.0248). The prevalence of anemia was much higher than in the overall female population (79%). The higher education was not a protective factor for anemia in women when analysed separately from the total population of women.

    Full Text Available Purpose : The association between iron deficiency anemia and febrile convulsion in infants has been examined in several studies with conflicting results. Therefore, the authors aimed to evaluate the precise relationship involved. Methods : In this case-control study, the authors assessed 100 children with a diagnosis of febrile convulsion, aged between 9 months and 2 years, during January 2007 to July 2009. The control group consisted of 100 febrile children without convulsion; controls were closely matched to the cases by age, gender, and underlying disease. Results : The mean ages of the febrile convulsion and control group were 16.3¡?#?.4 ;and 15.8¡?#?.1 ;months, respectively, and the two groups had no differences in clinical features. Iron deficiency anemia (Hb &lt;10.5 gm/dL was more frequent in the febrile convulsion group than in the control group, although there was no statistical significance. Unexpectably, the RDW (red blood cell distribution width was significantly lower and the MCNC (mean corpuscular hemoglobin concentration was significantly higher among seizure cases than among the controls (P&lt;0.05. There is no statistical difference between simple and complex febrile groups in the clinical and laboratory profiles. On multiple logistic regression analysis, iron deficiency anemia was more frequent, but the RDW was lower, among the cases with febrile convulsion, compared with the controls. Conclusions : Our study suggests that the iron deficiency anemia is associated with febrile convulsion, and screening for iron deficiency anemia should be considered in children with febrile convulsions.

    Full Text Available Anemia is a complication commonly encountered in malignancy, especially of hematological origin, either at presentation or during the course of treatment. Anemia of chronic disease, a condition characterized by disordered iron metabolism, shortened RBC half-life and inefficient erythropoiesis, is the major contributor to cancer anemia. Anemia effects up to 90% of Cancer patients with more than 60% requiring blood transfusion during or after treatment with the advent of recombinant human Erythropoietin (rHuEPO, an alternative to red blood cell transfusion has become available rHuEPO is now widely used in Cancer patients, as it improves hematocrit, lowers blood transfusion requirements and improves quality of life. So far, three drugs have been approved for the treatment of anemia in patients with malignancies (epoetin Alfa epoetin Beta and darbopoetin Alfa. New concepts for the cure of erythropoietin in cancer patients include 3 and 4 weekly dosing, as well as loading dose concepts. Although three rHuEPOs act on the same erythropoietin receptors, there are some variations on the degree of glycolylation, which lead to the differences in the pharmacokinetics and pharmacodynamics among the RhuEPOs. The cost effectiveness and medical justification of the administration of RHuEPO in tumor patients with respect to its positive effects on tumor oxygenation, tumor growth inhibition and support of chemo and radiotherapy is still a matter of debate. The largest systematic review on the use of erythropoietin in cancer patients undergoing treatment indicates a suggestive but not significant survival advantage of erythropoietin treated patients. Besides highlighting both the historical and functional aspects of RHuEPO, this review discusses the applications of RHUEPO in oncology.

    Full Text Available Embora o ferro por via oral seja considerado a primeira opção de tratamento da deficiência de ferro, em algumas situações específicas, a administração de ferro por via parenteral é uma opção terapêutica que deve ser considerada. Diferentemente do ferro dextran de alto peso molecular utilizado na década de 80 e lembrado como um composto associado ao alto risco de reação anafilática e morte, o desenvolvimento e comercialização de novos compostos com ferro para uso parenteral, sobretudo por via endovenosa - como o ferro sacarato, ferro gluconato e, mais recentemente, a carboximaltose férrica - , tem se tornado cada vez mais uma alternativa terapêutica segura e efetiva, e tem possibilitado ampliar o leque de indicações desta modalidade de tratamento além da nefrologia, como obstetrícia e ginecologia, cirurgia, pediatria, gastroenterologia, hematologia e hemoterapia. Os autores revisam as principais indicações do tratamento com ferro por via parenteral, analisam as principais drogas disponíveis para a correção da anemia ferropriva por via endovenosa e propõem uma estratégia de investigação diagnóstica, tratamento e seguimento laboratorial dos pacientes com indicação desta opção terapêutica.Although oral iron is generally considered the first choice in the treatment of iron deficiency, in some specific situations, parenteral iron administration is a therapeutic option that should be considered. Different to the high-molecular-weight iron dextran utilized in the eighties and remembered as a compound associated with a high risk of anaphylaxis and death, the development and marketing of newer preparations for parenteral, in particular endovenous, administration, such as iron sucrose, ferric gluconate and more recently ferric carboxymaltose, are becoming a more effective and safe therapeutic alternative, that have extended the range of indications beyond nephrology to obstetrics and gynecology, surgery, pediatrics

  10. An experimental investigation of the hemodynamic variations due to aplastic vessels within three-dimensional phantom models of the Circle of Willis.

    A complete circle of Willis (CoW) is found in approximately 30-50% of the population. Anatomical variations, such as absent or surgically clamped vessels, can result in undesirable flow patterns. These can affect the brain\\'s ability to maintain cerebral perfusion and the formation of cerebral aneurysms. An experimental test system was developed to simulate cerebral physiological conditions through three flexible 3D patient-specific models of complete and incomplete CoW geometries. Flow visualizations were performed with isobaric dyes and the mapped dye streamlines were tracked throughout the models. Three to seven flow impact locations were observed for all configurations, corresponding to known sites for aneurysmal formation. Uni and bi-directional cross-flows occurred along the communicating arteries. The greatest shunting of flow occurred for a missing pre-communicating anterior (A1) and posterior (P1) cerebral arteries. The anterior cerebral arteries had the greatest reduction (15-37%) in efferent flow rates for missing either a unilateral A1 or bilateral P1 segments. The bi-directional cross-flows, with multiple afferent flow mixing, observed along the communicating arteries may explain the propensity of aneurysm formation at these sites. Reductions in efferent flow rates due to aplastic vessel configurations may affect normal brain function.

    During a review of patients admitted with thromboangiitis obliterans (TAO), there was evidence of normochromic normocytic anemia and abrupt changes in hemoglobin (Hgb) levels in patients with several hospital admissions. Therefore, the evidence of hemolytic anemia was evaluated based on 37 banked plasma samples taken from Caucasian male TAO patients during disease exacerbation between 2012 and 2014. The patients' hospital records, including clinical manifestations and complete blood count, were evaluated. The following tests were performed on all samples: indirect antiglobulin test (IAT), C-reactive protein (CRP), high-sensitivity CRP (hsCRP), lactate dehydrogenase (LDH), haptoglobin, indirect bilirubin, d-aspartate aminotransferase (AST), and d-alanine aminotransferase (ALT). The mean age of the patients was 40 ± 7 years. Two patients underwent below-knee amputation. The mean hospital-documented Hgb of the patients was 12.9 ± 2.6 g/dL. CRP and IAT were positive in 75.6 and 70.2% of the samples, respectively. The tests and corresponding results were as follows: hsCRP, 14.07 ± 2.37 µg/mL; LDH, 2,552 ± 315 u/L; haptoglobin, 2.27 ± 1.1 g/L; indirect bilirubin, 0.09 ± 0.04 mg/dL; AST, 67 ± 7 u/L; and ALT, 26 ± 3 u/L. There was a significant inverse correlation between hsCRP and hospital-documented Hgb level (p = 0.03). Anemia with the positive IAT in most of the samples, high LDH and AST, and normal ALT are suggestive of hemolytic anemia. Normal indirect bilirubin is consistent with intravascular hemolysis. The positive CRP and elevated haptoglobin levels could be due to systemic inflammation in TAO. However, it is not known if an autoantigen or an infectious antigen is responsible for TAO systemic inflammation and induction hemolytic anemia. As such, the underlying mechanism of anemia in TAO could be part of the footprint of its main etiology. PMID:27574381

    2010-01-01

    Full Text Available Background : Anemias are the blood disorders characterized by reduction in the number of circulating red blood cells, the amount of hemoglobin, or the volume of packed red cells in blood. Chromosomal aberrations have often been reported from the bone marrow as well as cultured lymphocytes of the anemic patients. Aims: The aims of the study were to find out the commonest type of anemia occurring in the population of Jammu, India and to find out the chromosomal changes involved in the disorder. Material and Methods: Present study has been carried out on the bone marrow samples from 53 clinically diagnosed anemic patients. Cytogenetic study was carried out on slides prepared from these samples. Noncytogenetic factors like age, sex, religion, blood groups, family history of anemia, socioeconomic status, etc. have also been included in the study. Results: Megaloblastic anemia was found to be the commonest type of anemia. Centromere stretching, chromatid breaks, gaps, and elongation of chromosomes were recorded in patients with megaloblastic anemia and combined deficiency anemia. However, structural changes and numerical changes were totally absent. Conclusion: The commonest anemia among the people of Jammu region is megaloblastic anemia and its prevalence is increasing every year. Also, megaloblastic anemia is always associated with reversible cytogenetic changes.

  15. Iron Deficiency and Other Types of Anemia in Infants and Children.

    Anemia, defined as a hemoglobin level two standard deviations below the mean for age, is prevalent in infants and children worldwide. The evaluation of a child with anemia should begin with a thorough history and risk assessment. Characterizing the anemia as microcytic, normocytic, or macrocytic based on the mean corpuscular volume will aid in the workup and management. Microcytic anemia due to iron deficiency is the most common type of anemia in children. The American Academy of Pediatrics and the World Health Organization recommend routine screening for anemia at 12 months of age; the U.S. Preventive Services Task Force found insufficient evidence to assess the benefits vs. harms of screening. Iron deficiency anemia, which can be associated with cognitive issues, is prevented and treated with iron supplements or increased intake of dietary iron. The U.S. Preventive Services Task Force found insufficient evidence to recommend screening or treating pregnant women for iron deficiency anemia to improve maternal or neonatal outcomes. Delayed cord clamping can improve iron status in infancy, especially for at-risk populations, such as those who are preterm or small for gestational age. Normocytic anemia may be caused by congenital membranopathies, hemoglobinopathies, enzymopathies, metabolic defects, and immune-mediated destruction. An initial reticulocyte count is needed to determine bone marrow function. Macrocytic anemia, which is uncommon in children, warrants subsequent evaluation for vitamin B12 and folate deficiencies, hypothyroidism, hepatic disease, and bone marrow disorders. PMID:26926814

    Full Text Available Objective. Pyelonephritis is a common infectious morbidity of pregnancy. Though anemia is commonly associated with pyelonephritis, there are little data describing the effect of pyelonephritis with anemia on pregnancy outcomes. The purpose of this study was to further assess the association of anemia with infectious morbidity and pregnancy complications among women with pyelonephritis. Study Design. We conducted a retrospective cohort study of pregnant women admitted to Duke University Hospital between July 2006 and May 2012 with pyelonephritis. Demographic, laboratory, and clinical data from the subject’s pregnancy and hospitalizations were analyzed. Patients with pyelonephritis and anemia (a hematocrit < 32 were compared to those without anemia. Descriptive statistics were used to compare the two groups. Results. 114 pregnant women were admitted with pyelonephritis and 45 (39.5% had anemia on admission. There was no significant difference in age, race, preexisting medical conditions, or urine bacterial species between patients with anemia and those without. Women with anemia were more likely to deliver preterm (OR 3.3 (95% CI 1.07, 11.4, . When controlling for race and history of preterm delivery, women with anemia continued to have increased odds of preterm birth (OR 6.0, CI 1.4, 35, . Conclusion. Women with pyelonephritis and anemia are at increased risk for preterm delivery.

    Full Text Available Thiamine responsive megaloblastic anemia (TRMA, also known as Roger syndrome is an autosomal recessive disorder resulting from the deficiency of thiamine (Vitamin B1 transporter protein. This is the report of a 3- year follow up of a female child who presented in 2000 at the age of 11 with severe anemia, congenital deafness and diabetes mellitus. In our follow-up period we prescribed 100-mg thiamine tablet daily and after that there was a rise in her hemoglobin level to normal. Her hyperglycemia was controlled during the early phase of treatment. It recurred several months after start of treatment, but needed lower doses of insulin for control. Hearing loss did not respond to thiamine. Presently, the patient is apparently in good condition with normal hemoglobin level.

    Full Text Available La anemia por deficiencia de hierro es uno de los problemas nutricionales de mayor magnitud en el mundo. A pesar de conocer su etiología y tener a disposición el conocimiento de cómo enfrentarla y de saber que las intervenciones son de bajo costo, aún no se ha podido superar este problema. Este documento parte de una estimación de la magnitud del problema y plantea los elementos necesarios para el diseño, la ejecución y la medición del impacto de la suplementación con hierro y la fortificación, como las intervenciones más efectivas para disminuir considerablemente la dimensión de la anemia por falta de hierro. Propone una lista de pasos a seguir previos a la elaboración de un proyecto y recomienda una serie de elementos a considerar en ello. Define, asimismo, los aspectos que se deben incluir en una propuesta de fortificación y en otra de suplementación. El documento concluye con un listado de actividades complementarias que la Organización Panamericana de la Salud/Organización Mundial de la Salud ofrece dentro de su paquete de cooperación técnica.Iron deficiency anemia is among the greatest nutritional problems in the world. Although its etiology is understood and intervention at low cost is available, the problem persists. The present review begins with a general estimate of the dimensions of the problem. It suggests the necessary elements for the design, implementation, and measurement of the impact of iron supplementing and fortification as the most effective forms to intervene and diminish iron deficiency anemia. Several preliminary steps are proposed previous to the preparation of a project and several recomendations are made to be included in a project for fortification and iron supplementing. A list of complementary activities offered by PAHO/WHO as part of the package of technical cooperation is included.
