Aplastic anaemia affects the entire bone marrow. This prospective study was undertaken to develop and standardise a new nuclear medicine technique called 'dynamic bone marrow imaging'. Eleven patients and ten controls were studied. Serial images of the pelvis were obtained in frame mode following intravenous injection of 185-370 mBq of 99m Tc S. Colloid, and an index, called the bone marrow uptake index was calculated by taking into consideration the time activity curve obtained over the iliac crest. This was followed by static imaging of the entire bone marrow in all cases. It was possible to obtain excellent information regarding topographic distribution of bone marrow as well as detect early changes in bone marrow function following treatment. An attempt was also made to correlate bone marrow cellularity as obtained by bone marrow biopsy with results of dynamic bone marrow scintigraphy. On the basis of the encouraging results obtained in the present study, the authors feel that dynamic bone marrow imaging is an excellent technique for the objective evaluation of bone marrow in aplastic anaemia. 20 refs.; 4 figs.; 5 tabs

Of 75 patients with asplastic anaemia treated between 1968 and 1975, 33 were retrospectively considered as potential candidates for allogenegic bone-marrow transplantation on the basis of their age and severity of marrow failure. The prognosis of these patients with conservative treatment was assessed from parameters obtained at the time of the initial diagnosis. Initial peripheral-blood granulocyte or platelet concentrations were not of porgnostic value. In contrast, initial reticulocyte concentrations, allowed separation of the patients into two groups with poor and good prognosis. Low initial reticulocyte concentrations (less than 10 000/mu1) indicated those patients at extremely high risk of succumbing to their marrow aplasia (there were no survivors 36 months after disgnosis). In contrast, 75% of those patients with more than 10 000 reticulocytes per mu1 at diagnosis survived for 3 years. Initial peripheral-blood reticulocyte concentrations thus appear to indicate the extent of the marrow failure in aplastic anaemia more accurately than granulocytes or platelets. Low initial reticulocyte concentrations may indicate, among patients with severe aplastic anaemia, those for whom allogeneic bone-marrow transplantation should be seriously considered; patients with higher initial reticulocyte concentrations may benefit from conservation treatment.

Six patients with severe aplastic anaemia received a bone-marrow graft after conditioning with cyclophosphamide and total lymphoid irradiation (TLI). No rejections occurred. Acute graft-versus-host disease developed in 3 patients and was fatal in one. Another patient died from systemic aspergillus infection. Chronic GVHD of the skin developed in a patient who was grafted with bone marrow from her HLA-phenotypically identical father. These data suggest that conditioning with cyclophosphamide and TLI is a promising regimen. (orig.) [de

The extent of DNA-repair induced by UV-C irradiation was measured in peripheral unstimulated lymphocytes of 24 patients with aplastic anaemia at different stages of disease and compared with the results obtained in 92 controls. As parameter of the DNA-repair synthesis, the incorporation of (/sup 3/H)thymidine in the presence of 2 mmol/l hydroxyurea (HU) was taken. Of 19 patients tested after treatment with antilymphocyte globulin (ALG), 5 were in complete autologous haemopoietic remission, defined as > 1000 granulocytes/mm/sup 3/, > 100 000 platelets/mm/sup 3/ and a nontransfused haemoglobin value > 10 g%. 14 patients were in partial remission, defined as improvement of haemopoietic function, not meeting the criteria for complete remission. 4/5 patients in complete remission had normal DNA-repair synthesis, compared to 4/14 patients in partial remission. In 92 controls, a normal level was found in 70 cases. In 4/5 patients examined at diagnosis and at various intervals after ALG-treatment, DNA-repair synthesis was low at diagnosis. It increased after therapy and paralleled improvement of haemopoietic function to some extent. It is suggested that in aplastic anaemia there are different populations of lymphocytes with differing DNA-repair capacity; ALG treatment seems to favour expansion of the normal population, which is associated with improvement of haemopoietic function.

Aplastic anaemia preceding acute lymphoblastic leukaemia in an adult with isolated deletion of chromosome 9q.

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.

Full text: We present a case of a 39 year old previously well woman who developed carbimazole-induced acute aplastic anaemia. Following 6 weeks of carbimazole for Grave's disease she presented with fever, sore throat and lethargy and was found to be pancytopaenic. Haemoglobin fell to 79g/l (normal>120g/l), neutrophils to an undetectable level and platelets to 4,000/ml (normal>150,000/ml). From the MIRD schema it was estimated that a therapeutic dose of 444 MBq (12mCi) to treat her hyperthyroidism would deliver a red marrow radiation dose of about 30 mSv, at least an order of magnitude below any expected demonstrable deleterious effect on the marrow. Subsequently a dose of 444 MBq of I-131 was given and within 2 weeks the marrow had begun to recover, eventually to normal. This case would support the use of 1-131 for hyperthyroidism in carbimazole-induced marrow aplasia, even in profoundly depressed marrow

Aplastic anemia is an acquired bone marrow failure characterized by marrow hypoplasia, a paucity of hematopoietic stem and progenitor cells, and pancytopenia of the peripheral blood, due to immune attack on the bone marrow. In aplastic anemia, a major challenge is to develop immune biomarkers to monitor the disease. We measured circulating microRNAs in plasma samples of aplastic anemia patients in order to identify disease-specific microRNAs. A total of 179 microRNAs were analyzed in 35 plasma samples from 13 aplastic anemia patients, 11 myelodysplastic syndrome patients, and 11 healthy controls using the Serum/Plasma Focus microRNA Polymerase Chain Reaction Panel. Subsequently, 19 microRNAs from the discovery set were investigated in the 108 plasma samples from 41 aplastic anemia patients, 24 myelodysplastic syndrome patients, and 43 healthy controls for validation, confirming that 3 microRNAs could be validated as dysregulated (>1.5-fold change) in aplastic anemia, compared to healthy controls. MiR-150-5p (induction of T-cell differentiation) and miR-146b-5p (involvement in the feedback regulation of innate immune response) were elevated in aplastic anemia plasma, whereas miR-1 was decreased in aplastic anemia. By receiver operating characteristic curve analysis, we developed a logistic model with these 3 microRNAs that enabled us to predict the probability of a diagnosis of aplastic anemia with an area under the curve of 0.86. Dysregulated expression levels of the microRNAs became normal after immunosuppressive therapy at 6 months. Specifically, miR-150-5p expression was significantly reduced after successful immunosuppressive therapy, but did not change in non-responders. We propose 3 novel plasma biomarkers in aplastic anemia, in which miR-150-5p, miR-146b-5p, and miR-1 can serve for diagnosis and miR-150-5p for disease monitoring.

Maria Stella Figueiredo

Full Text Available CONTEXT: The prognosis of severe aplastic anemia has improved since the introduction of bone marrow transplantation and treatment with antithymocyte globulin. In contrast to the success of these protocols, studies with long term follow-up have shown the occurrence of clonal diseases such as paroxysmal nocturnal hemoglobinuria, myelodysplastic syndrome and acute leukemia in aplastic anemia. CASE REPORT: We report the first case of a Brazilian patient with aplastic anemia who developed myelodysplastic syndrome and acute myeloid leukemia showing acquired hemoglobin H and increased fetal hemoglobin.

The incidence of graft rejection was determined in 66 children with acquired aplastic anaemia (AA) following bone marrow transplantation (BMT) from a related donor. Eleven of 65 evaluable patients experienced either early or late rejection. Multivariate analysis identified previous immunosuppressive therapy with antithymocyte-globulin (ATG) and ciclosporin (CsA) as a risk factor for graft rejection (relative risk: 16.6, P = 0.001). Patients who received ATG and CsA had a significantly lower probability of failure-free survival than those who did not (69.7 +/- 6.2% vs. 87.9 +/- 8.0%, P = 0.044). These results suggest that BMT should be instituted immediately in children with severe AA who have human leucocyte antigen-identical siblings.

Total lymph-node irradiation and pretreatment with cyclophosphamide in preparation for bone-marrow grafting for aplastic anaemia

1981-01-01

Bone-marrow transplantation (BMT), using bone marrow from an HLA-identical brother or sister constitutes the treatment of choice in most young patients with severe aplastic amaemia. The cases are described of 6 patients who were prepared for grafting by administration of cyclophosphamide (4 days, 50 mg/kg body weight day) and total lymph-node irradiation (750 rad in a single dose). One patient died on the 26th day after BMT from a disseminated Aspergillus infection, and another on the 28th day from the consequences of graft-versus-host disease (GVH disease). One patient recovered after an episode of GVH disease. Two patients developed no complications after the grafting. One female patient, who for the lack of an HLA-identical brother or sister had been grafted with bone marrow of her father whose HLA-phenotype was identical, was normalized haematologically but developed chronic GVH disease of the skin. This method of preparation for BMT for aplastic anaemia reduces the risk of rejection of the bone marrow to a minimum, and may well reduce the frequency and severity of GVH disease. (Auth.)

1989-01-01

Fifteen haematological disorders including ten leukaemia cases, one primary acquired sideroblastic anaemia and four aplastic anaemia cases were studied clinicopathologically in autopsies from patients who had been administered Thorotrast in Japan. The leukaemia group, the primary acquired sideroblastic anaemia and the aplastic anaemia cases after Thorotrast administration were considered to be mainly atypical, and it was speculated that damage induced by Thorotrast may affect the haemopoietic stem cell level and the haemopoietic microenvironment. Both dose rate and absorbed dose estimated in bone marrow, spleen and liver at autopsy showed no significant difference between the leukaemia group, primary acquired sideroblastic anaemia, aplastic anaemia and non-haematological disorders excluding the malignant hepatic tumours and liver cirrhosis.

Cytokines IL-2 and IL-8 both participate in immune regulation. However, the relationship between polymorphisms in these two cytokines and the risk of acquired aplastic anemia (acquired AA) has not been explored. We selected five SNPs including rs11575812, rs2069772 and rs2069762 of IL-2, rs2227306 and rs2227543 of IL-8. SNaPshot genotyping was used to test the genotypes of IL-2 and IL-8 polymorphisms in a population of 101 acquired AA patients and 165 healthy controls. The rs2069762 G allele appeared to be a protective mutation, but no significant differences were found in other four SNPs. We also found that rs2069762 had an impact on the transcriptional regulation. It could be assumed that the rs2069762 polymorphism might reduce the risk of acquired aplastic anemia, while the remaining four SNPs might not contribute to susceptibility to acquired AA in a Chinese population. © 2017 The Author(s)Published by S.

Mesenchymal Stem Cell Benefits Observed in Bone Marrow Failure and Acquired Aplastic Anemia

Science.gov (United States)

Gonzaga, Vivian Fonseca; Lisboa, Gustavo Sabino; Frare, Eduardo Osório

2017-01-01

Acquired aplastic anemia (AA) is a type of bone marrow failure (BMF) syndrome characterized by partial or total bone marrow (BM) destruction resulting in peripheral blood (PB) pancytopenia, which is the reduction in the number of red blood cells (RBC) and white blood cells (WBC), as well as platelets (PLT). The first-line treatment option of AA is given by hematopoietic stem cell (HSCs) transplant and/or immunosuppressive (IS) drug administration. Some patients did not respond to the treatment and remain pancytopenic following IS drugs. The studies are in progress to test the efficacy of adoptive cellular therapies as mesenchymal stem cells (MSCs), which confer low immunogenicity and are reliable allogeneic transplants in refractory severe aplastic anemia (SAA) cases. Moreover, bone marrow stromal cells (BMSC) constitute an essential component of the hematopoietic niche, responsible for stimulating and enhancing the proliferation of HSCs by secreting regulatory molecules and cytokines, providing stimulus to natural BM microenvironment for hematopoiesis. This review summarizes scientific evidences of the hematopoiesis improvements after MSC transplant, observed in acquired AA/BMF animal models as well as in patients with acquired AA. Additionally, we discuss the direct and indirect contribution of MSCs to the pathogenesis of acquired AA. PMID:29333168

Chromosome anomalies in bone marrow as primary cause of aplastic or hypoplastic conditions and peripheral cytopenia: disorders due to secondary impairment of RUNX1 and MPL genes

Directory of Open Access Journals (Sweden)

Marletta Cristina

2012-10-01

Full Text Available Abstract Background Chromosome changes in the bone marrow (BM of patients with persistent cytopenia are often considered diagnostic for a myelodysplastic syndrome (MDS. Comprehensive cytogenetic evaluations may give evidence of the real pathogenetic role of these changes in cases with cytopenia without morphological signs of MDS. Results Chromosome anomalies were found in the BM of three patients, without any morphological evidence of MDS: 1 an acquired complex rearrangement of chromosome 21 in a boy with severe aplastic anaemia (SAA; the rearrangement caused the loss of exons 2–8 of the RUNX1 gene with subsequent hypoexpression. 2 a constitutional complex rearrangement of chromosome 21 in a girl with congenital thrombocytopenia; the rearrangement led to RUNX1 disruption and hypoexpression. 3 an acquired paracentric inversion of chromosome 1, in which two regions at the breakpoints were shown to be lost, in a boy with aplastic anaemia; the MPL gene, localized in chromosome 1 short arms was not mutated neither disrupted, but its expression was severely reduced: we postulate that the aplastic anaemia was due to position effects acting both in cis and in trans, and causing Congenital Amegakaryocytic Thrombocytopenia (CAMT. Conclusions A clonal anomaly in BM does not imply per se a diagnosis of MDS: a subgroup of BM hypoplastic disorders is directly due to chromosome structural anomalies with effects on specific genes, as was the case of RUNX1 and MPL in the patients here reported with diagnosis of SAA, thrombocytopenia, and CAMT. The anomaly may be either acquired or constitutional, and it may act by deletion/disruption of the gene, or by position effects. Full cytogenetic investigations, including a-CGH, should always be part of the diagnostic evaluation of patients with BM aplasia/hypoplasia and peripheral cytopenias.

The aim of this study was to evaluate the clinical presentation of aplastic anemia as well as to assess the efficacy of Cyclosporin -A in patients with aplastic anemia. This is a hospital based interventional study. During the three year study period, 44 children were enrolled. Mean age was 9.3 years and there was a male predominance. Most common clinical presentation was anemia and bleeding. Four children died before therapy was started. Cyclosporin-A was started in 40 patients. Eleven patients died before completion of therapy and three patients were lost to follow-up. Out of 26 patients who completed therapy, 11 were cured and 9 were responders while 6 were non responders according to the selected criteria. In developing third world countries like Pakistan majority of the patients with aplastic anemia cannot afford BMT. Alternative modalities of treatment must therefore be looked into. Cyclosporin-A seems to be a reasonable therapeutic option in such cases. (author)

Emerging evidence indicates that microRNA control and modulate immunity. MicroRNA have not been investigated in acquired aplastic anemia, a T-cell-mediated immune disease. Analysis of 84 microRNA expression levels in CD4(+) and CD8(+) T cells of patients with aplastic anemia revealed concurrent down-regulation of miR-126-3p, miR-145-5p, miR-223-3p, and miR-199a-5p (>3-fold change, Paplastic anemia compared to other hematologic disorders. MiR-126-3p and miR-223-3p were down-regulated in CD4(+) T effector memory cells, and miR-126-3p, miR-145-5p, and miR-223-3p were down-regulated in CD8(+) T effector memory and terminal effector cells. Successful immunosuppressive therapy was associated with restoration to normal expression levels of miR-126-3p, miR-145-5p, and miR-223-3p (>2-fold change, Paplastic anemia patients, MYC and PIK3R2 were up-regulated and proved to be targets of miR-145-5p and miR-126-3p, respectively. MiR-126-3p and miR-145-5p knockdown promoted proliferation and increased interferon-γ and granzyme B production in both CD4(+) and CD8(+) T cells. Our work describes previously unknown regulatory roles of microRNA in T-cell activation in aplastic anemia, which may open a new perspective for development of effective therapy.

Acquired aplastic anemia is an idiopathic paradigm of human bone marrow failure syndrome, which involves active destruction of hematopoietic stem cells and progenitors by cytotoxic T cells in the bone marrow. Aberrant expression of microRNAs in T cells has been shown to lead to development of certain autoimmune diseases. In the present study, we performed a microarray analysis of miRNA expression in bone marrow CD3+ T cells from patients with aplastic anemia and healthy controls. Overexpression of miR34a and underexpression of its target gene diacylglycerol kinase (DGK) ζ in bone marrow mononuclear cells were validated in 41 patients and associated with the severity of aplastic anemia. Further, the level of miR34a was higher in naïve T cells from patients than from controls. The role of miR34a and DGKζ in aplastic anemia was investigated in a murine model of immune-mediated bone marrow failure using miR34a-/- mice. After T-cell receptor stimulation in vitro, lymph node T cells from miR34a-/- mice demonstrated reduced activation and proliferation accompanied with a less profound down-regulation of DGKζ expression and decreased ERK phosphorylation compared to those from wild-type C57BL6 control mice. Infusion of 5 × 106 miR34a-/- lymph node T cells into sublethally irradiated CB6F1 recipients led to increased Lin-Sca1+CD117+ cells and less vigorous expansion of CD8+ T cells than injection of same number of wild-type lymph node cells. Our study demonstrates that the miR34a/DGKζ dysregulation enhances T-cell activation in aplastic anemia and targeting miR34a may represent a novel molecular therapeutic approach for patients with aplastic anemia.

Hematopoietic stem cell transplantation for acquired aplastic anemia

Purpose of review There has been steady improvement in outcomes with allogeneic bone marrow transplantation (BMT) for severe aplastic anemia (SAA), due to progress in optimization of the conditioning regimens, donor hematopoietic cell source and supportive care. Here we review recently published data that highlight the improvements and current issues in the treatment of SAA. Recent findings Approximately one-third of AA patients treated with immune suppression therapy (IST) have acquired mutations in myeloid cancer candidate genes. Because of the greater probability for eventual failure of IST, human leukocyte antigen (HLA)-matched sibling donor BMT is the first-line of treatment for SAA. HLA-matched unrelated donor (URD) BMT is generally recommended for patients who have failed IST. However, in younger patients for whom a 10/10-HLA-allele matched URD can be rapidly identified, there is a strong rationale to proceed with URD BMT as first-line therapy. HLA-haploidentical BMT using post-transplant cyclophosphamide (PT-CY) conditioning regimens, is now a reasonable second-line treatment for patients who failed IST. Summary Improved outcomes have led to an increased first-line role of BMT for treatment of SAA. The optimal cell source from an HLA-matched donor is bone marrow. Additional studies are needed to determine the optimal conditioning regimen for HLA-haploidentical donors. PMID:27607445

Survival in severe aplastic anemia (SAA) has markedly improved in the past 4 decades because of advances in hematopoietic stem cell transplantation, immunosuppressive biologics and drugs, and supportive care. However, management of SAA patients remains challenging, both acutely in addressing the immediate consequences of pancytopenia and in the long term because of the disease's natural history and the consequences of therapy. Recent insights into pathophysiology have practical implications. We review key aspects of differential diagnosis, considerations in the choice of first- and second-line therapies, and the management of patients after immunosuppression, based on both a critical review of the recent literature and our large personal and research protocol experience of bone marrow failure in the Hematology Branch of the National Heart, Lung, and Blood Institute.

Disrupted lymphocyte homeostasis in hepatitis‐associated acquired aplastic anemia is associated with short telomeres

Hepatitis‐associated aplastic anemia (HAA) is a variant of acquired aplastic anemia (AA) in which immune‐mediated bone marrow failure (BMF) develops following an acute episode of seronegative hepatitis. Dyskeratosis congenita (DC) is an inherited BMF syndrome characterized by the presence of short telomeres, mucocutaneous abnormalities, and cancer predisposition. While both conditions may cause BMF and hepatic impairment, therapeutic approaches are distinct, making it imperative to establish the correct diagnosis. In clinical practice, lymphocyte telomere lengths (TL) are used as a first‐line screen to rule out inherited telomeropathies before initiating treatment for AA. To evaluate the reliability of TL in the HAA population, we performed a retrospective analysis of TL in 10 consecutively enrolled HAA patients compared to 19 patients with idiopathic AA (IAA). HAA patients had significantly shorter telomeres than IAA patients (P = 0.009), including four patients with TL at or below the 1st percentile for age‐matched controls. HAA patients had no clinical features of DC and did not carry disease‐causing mutations in known genes associated with inherited telomere disorders. Instead, short TLs were significantly correlated with severe lymphopenia and skewed lymphocyte subsets, features characteristic of HAA. Our results indicate the importance of caution in the interpretation of TL measurements in HAA, because, in this patient population, short telomeres have limited specificity. Am. J.

Introduction Acquired severe aplastic anemia (SAA) is a rare and progressive disease characterized by an immune-mediated functional impairment of hematopoietic stem cells. Transplantation of these cells is a first-line treatment option if HLA-matched related donors are available. First-line immunosuppressive therapy may be offered as alternative. The aim was to compare the outcome of these patients in controlled trials. Methods A systematic search was performed in the bibliographic databases MEDLINE, EMBASE, and The Cochrane Library. To show an overview of various outcomes by treatment group we conducted a meta-analysis on overall survival. We evaluated whether studies reported statistically significant factors for improved survival. Results 26 non-randomized controlled trials (7,955 patients enrolled from 1970 to 2001) were identified. We did not identify any RCTs. Risk of bias was high except in 4 studies. Young age and recent year of treatment were identified as factors for improved survival in the HSCT group. Advanced age, SAA without very severe aplastic anemia, and combination of anti-lymphocyte globulin with cyclosporine A were factors for improved survival in the IST group. In 19 studies (4,855 patients), summary statistics were sufficient to be included in meta-analysis. Considerable heterogeneity did not justify a pooled estimate. Adverse events were inconsistently reported and varied significantly across studies. Conclusions Young age and recent year of treatment were identified as factors for improved survival in the transplant group. Advanced age, SAA without very severe aplastic anemia, and combination of anti-lymphocyte globulin with cyclosporine A were factors for improved survival in the immunosuppressive group. Considerable heterogeneity of non-randomized controlled studies did not justify a pooled estimate. Adverse events were inconsistently reported and varied significantly across studies. PMID:21541024

Acquired aplastic anemia (AA) is a prototype of idiopathic bone marrow failure, which is caused by immune-mediated destruction of hematopoietic progenitors but is also characterized by frequent evolution to clonal myeloid disorders, such as myelodysplastic syndromes or acute myeloid leukemia. However, the chronological behavior of the clonality and its link to myelodysplastic syndrome or acute myeloid leukemia has not been fully explored. To define the clonality and its chronological behavior in AA, we performed targeted sequencing (N=439) in cases with AA. Somatic mutations were detected in 1/3 of our cases. Mutations were most frequently found in DNMT3A, followed by BCOR, PIGA and ASXL1. The prevalence of mutations increased with age. The clone sizes in DNMT3A and ASXL1 were prone to increase, whereas those of BCOR and PIGA were more likely to decrease or remain stable. Mutations in PIGA, BCOR and BCORL1 correlated with a better response to immunosuppressive therapy and more favorable survival. On the other hand, other mutations were associated with worse outcomes. The chronological dynamics of clonality showed marked variability and were not necessarily associated with prognosis.

We have analyzed 1448 patients with acquired aplastic anemia grafted between 2005 and 2009, and compared outcome of identical sibling (n=940) versus unrelated donor (n=508) transplants. When compared to the latter, sibling transplants were less likely to be performed beyond 180 days from diagnosis.......04). In conclusion, in multivariate analysis, the outcome of unrelated donor transplants for acquired aplastic anemia, is currently not statistically inferior when compared to sibling transplants, although patients are at greater risk of acute and chronic graft-versus-host disease. The use of peripheral blood grafts...

Liver histology is characterized by T cell infiltrating the parenchyma as reported in acute hepatitis. Recently in HAA it has been demonstrated intrahepatic  and blood lymphocytes with  T cell repertoire similar to that of confirmed viral acute hepatitis. The expanded T cell clones return to a normal distribution after response to immunosuppressive treatment, suggesting the antigen or T cell clearance. Therapeutic options are the same as acquired aplastic anemia.

Full Text Available Objective: To evaluate the outcome of children with severe acquired aplastic anemia treated with rabbit antithymocyte globulin and cyclosporine as first-line treatment at this institution. Methods: Retrospective analysis of 26 pediatric patients with aplastic anemia, treated between 1996 and 2011 with rabbit antithymocyte globulin plus cyclosporine. Results: The overall response rate at six months was 34.6% (9/26, and the cumulative incidence of relapse was 26.5% (95% confidence interval [CI]: 1.4%-66% at 5 years. The cumulative incidence of clonal evolution after immunosuppressive therapy was 8.3% (95% CI: 0.001%-53.7% at five years with both clonal evolutions in non -responders who acquired monosomy 7 karyotype. The overall survival at five years was 73.6% (95% CI: 49.2%-87.5%. Conclusions: The present results confirm the poor response rate with rabbit antithymocyte globulin as first therapy in pediatrics patients, similar to what has been reported for patients of all ages. This confirmation is problematic in Brazil, given the lack of horse antithymocyte globulin in many markets outside the United States.

In patients with acquired aplastic anemia, destruction of hematopoietic cells by the immune system leads to pancytopenia. Patients have a response to immunosuppressive therapy, but myelodysplastic syndromes and acute myeloid leukemia develop in about 15% of the patients, usually many months to years after the diagnosis of aplastic anemia. We performed next-generation sequencing and array-based karyotyping using 668 blood samples obtained from 439 patients with aplastic anemia. We analyzed serial samples obtained from 82 patients. Somatic mutations in myeloid cancer candidate genes were present in one third of the patients, in a limited number of genes and at low initial variant allele frequency. Clonal hematopoiesis was detected in 47% of the patients, most frequently as acquired mutations. The prevalence of the mutations increased with age, and mutations had an age-related signature. DNMT3A-mutated and ASXL1-mutated clones tended to increase in size over time; the size of BCOR- and BCORL1-mutated and PIGA-mutated clones decreased or remained stable. Mutations in PIGA and BCOR and BCORL1 correlated with a better response to immunosuppressive therapy and longer and a higher rate of overall and progression-free survival; mutations in a subgroup of genes that included DNMT3A and ASXL1 were associated with worse outcomes. However, clonal dynamics were highly variable and might not necessarily have predicted the response to therapy and long-term survival among individual patients. Clonal hematopoiesis was prevalent in aplastic anemia. Some mutations were related to clinical outcomes. A highly biased set of mutations is evidence of Darwinian selection in the failed bone marrow environment. The pattern of somatic clones in individual patients over time was variable and frequently unpredictable. (Funded by Grant-in-Aid for Scientific Research and others.).

Oligoclonal expansion of CD8 + CD28 - lymphocytes has been considered indirect evidence for a pathogenic immune response in acquired aplastic anemia. A subset of CD8 + CD28 - cells with CD57 expression, termed effector memory cells, is expanded in several immune-mediated diseases and may have a role in immune surveillance. We hypothesized that effector memory CD8 + CD28 - CD57 + cells may drive aberrant oligoclonal expansion in aplastic anemia. We found CD8 + CD57 + cells frequently expanded in the blood of aplastic anemia patients, with oligoclonal characteristics by flow cytometric Vβ usage analysis: skewing in 1-5 Vβ families and frequencies of immunodominant clones ranging from 1.98% to 66.5%. Oligoclonal characteristics were also observed in total CD8 + cells from aplastic anemia patients with CD8 + CD57 + cell expansion by T-cell receptor deep sequencing, as well as the presence of 1-3 immunodominant clones. Oligoclonality was confirmed by T-cell receptor repertoire deep sequencing of enriched CD8 + CD57 + cells, which also showed decreased diversity compared to total CD4 + and CD8 + cell pools. From analysis of complementarity-determining region 3 sequences in the CD8 + cell pool, a total of 29 sequences were shared between patients and controls, but these sequences were highly expressed in aplastic anemia subjects and also present in their immunodominant clones. In summary, expansion of effector memory CD8 + T cells is frequent in aplastic anemia and mirrors Vβ oligoclonal expansion. Flow cytometric Vβ usage analysis combined with deep sequencing technologies allows high resolution characterization of the T-cell receptor repertoire, and might represent a useful tool in the diagnosis and periodic evaluation of aplastic anemia patients.

To determine the clinico haematological features, treatment and outcome of children diagnosed with aplastic anemia at a single institution. Study Design: Observational study. Place and Duration of Study: The Aga Khan University Hospital, Karachi, from January 1999 till December 2008. Methodology: Medical records of children aged less than 15 years of age diagnosed with aplastic anemia were reviewed. Clinico haematological features, treatment and its response to therapy and outcome were recorded. Results were described in percentages. Results: Ninety patients were diagnosed to have aplastic anemia (AA); 65 were male during the study period. Age ranged from 1 to 15 years. Fever in 65 patients (72.2%), pallor in 53 (58.8%), skin bleeding in 49 (54.4%) and epistaxis in 31(34.4%) were the most common and frequent presenting features. Congenital (Fanconi's) anemia was found in 15 (16.6%) and acquired idiopathic in 75 (83.4%) of patients. Very severe aplastic anemia (VSAA) was seen in 29 (32.2%), 26 (28.9%) had severe AA and 17 (18.9%) had moderate AA. Eight patients (8.9%) underwent haematopoietic stem cell transplantation (HSCT), 12 (13.3%) received immunosuppressive therapy (IST) and 70 patients (77.7%) received other and supportive therapy. Five (62.5%) patients showed complete response to HSCT and 3 (37.5%) failed to engraft. IST showed complete response in 3 (25%), partial response in 5 (41.6%) and no response in 4 (33.3%). Twenty two patients (24.4%) expired either due to infection in 16 (72.7%, fungal in 6, bacterial in 10) and intracranial haemorrhage in 6 (27.3%) cases. Conclusion: Majority of cases with AA were acquired and idiopathic in etiology. VSAA and SAA were frequent. Response to HSCT and IST was sub-optimal. (author)

Aplastic anemia is a fatal bone marrow disorder characterized by peripheral pancytopenia and marrow hypoplasia. The disease can be hereditary or acquired and develops at any stage of life. A subgroup of the inherited form is caused by replicative impairment of hematopoietic stem and progenitor cells due to very short telomeres as a result of mutations in telomerase and other telomere components. Abnormal telomere shortening is also described in cases of acquired aplastic anemia, most likely secondary to increased turnover of bone marrow stem and progenitor cells. Here, we test the therapeutic efficacy of telomerase activation by using adeno-associated virus (AAV)9 gene therapy vectors carrying the telomerase Tert gene in 2 independent mouse models of aplastic anemia due to short telomeres (Trf1- and Tert-deficient mice). We find that a high dose of AAV9-Tert targets the bone marrow compartment, including hematopoietic stem cells. AAV9-Tert treatment after telomere attrition in bone marrow cells rescues aplastic anemia and mouse survival compared with mice treated with the empty vector. Improved survival is associated with a significant increase in telomere length in peripheral blood and bone marrow cells, as well as improved blood counts. These findings indicate that telomerase gene therapy represents a novel therapeutic strategy to treat aplastic anemia provoked or associated with short telomeres. © 2016 by The American Society of Hematology.

Immune suppression is a crucial pillar for treatment of aplastic anemia. Cyclosporine monotherapy is an easily available, affordable therapeutic option with good safety profile. This prospective study was conducted over a period of 2 years from June 2012 to July 2014. The diagnosis and response to treatment of aplastic anemia was established as per published criteria. Follow up was done at 3 and 6 months in order to assess the response. 57 patients of acquired aplastic anemia with median age of 37 years (6 to 81 years) were included in the study. 35 (62 %) cases were severe aplastic anemai, 16 (28 %) non severe aplastic anemia and 6 (10 %) were very severe aplastic anemia. At 3 months overall response rate (OR) was 7 (14 %) and at 6 months the OR rate of 11 (19.6 %) was achieved. Transiently raised creatinine, liver function abnormality and gum hypertrophy were the main side effects observed in this cohort. Oral cyclosporine monotherapy at dose of 5 mg/kg/day is a relatively safe treatment option for resource poor patients with aplastic anemia.

Fanconi anaemia, an autosomal recessive constitutional aplastic anaemia, seems to be related to a DNA repair mechanism defect. Bone marrow transplantation is the only treatment which can cure these patients. Previous attempts at BMT have shown an increased sensitivity to Cyclophosphamide used for the conditioning. Such a sensitivity has also been observed in vitro when Fanconi anaemia cells were incubated with alkylating agents. We have tested the in vivo radiosensitivity and cell repair after skin contact radiotherapy to calculate the irradiation dose which could be tolerated by FA patients. Eight patients have been tested and the results confirmed the suspected increased radiosensitivity in the majority of patients. Following these results, four patients were conditioned with low dose Cyclophosphamide (20 mg/kg) associated with 5 Grays thoraco-abdominal irradiation. All had a take and no major complication of the conditioning regimen. All are alive in good condition from day 51 to day 330 after transplant. Oesophagitis was one major unexpected complication. This study confirms the possibility of curing FA patients with BMT when the conditioning regimen is modified according to the pathophysiology of the disease.

Aim: Anaemia, if severe, causes multi systemic functional changes. We tried to find out the effect of severe anaemia on renal function. Materials and Methods: A total of 66 patients with severe anemia and 10 healthy controls were recruited in this study. The cases were divided into following groups: group A: patients with Hb≤3 gm/dl (n=33); group B: patients with Hb≤6 but > 3 gm/dl (n=33); group C: healthy controls with normal renal function and Hb>12gm/dl. Out of 66 anaemic patients, 36 had nutritional anaemia (mainly iron deficiency; group A=20, group B=16), 24 patients were suffering from aplastic anaemia (group A=11, group B=13) and rest 6 had megaloblastic anaemia (group A=2, group B=4). No subject had hypertension, diabetes, primary renal dysfunction or any other systemic illness, affecting kidney. Various renal function test parameters and diagnostic renal failure indices were obtained for all subjects. GFR with 2-sample method after injection of 99m-Tc DTPA and ERPF with single sample method after injection of 131-I OIH were also calculated. Results: Fourteen patients had mild to moderate pedal edema (10 in group A and 4 in group B). Out of these patients, 8 had palpable liver and signs of systemic congestion. Signs of raised systemic venous pressure (raised JVP) were found in 7 patients of group A. In about 55% of patients, chest x-ray showed mild to moderately enlarged heart with disturbed cardiophrenic angle. Urine output was >600 ml/day in all cases. Results are presented. All renal functional parameters and indices were significantly reduced in anaemic patients and were suggestive of pre-renal failure. The reduction was correlating well with the severity of anaemia.Conclusion: Severe anaemia leads to renal dysfunction with alteration of minor and major renal failure indices, which can be characterized by sub-clinical and pre-biochemical non-oliguric pre-renal failure

Acquired aplastic anemia (AA) is a rare heterogeneous disease characterized by pancytopenia and hypoplastic bone marrow. The incidence is 2-3/million inhabitants/year, in Europe, but higher in East Asia. Survival in severe aplastic anemia (SAA) has markedly improved in the past 2 decades because of advances in hematopoietic stem cell transplantation, immunosuppressive and biologic drugs, and supportive care. In SAA hematopoietic stem cell transplant (HSCT) from a matched sibling donor (MSD) is the treatment of choice. If a MSD is not available, the options include immunosuppressive therapy (IST) or unrelated donor HSCT. The objective of this guideline is to provide healthcare professionals with clear guidance on the diagnosis and management of pediatric patients with AA. A preliminary, evidence-based document issued by a group of pediatric hematologists was discussed, modified and approved during a series of "Consensus Conferences" according to procedures previously validated by the AIEOP Board. The guidelines highlight the importance of referring pediatric patients with AA to pediatric centers with long experience in diagnosis, differential diagnosis, management, supportive care and follow-up of AA.

22 and the morphology was normocytic normochromic in 20 cases. Tuberculosis leading to anaemia was seen in 24, Internal haemorrhoids/Fissures 5, Taenia infestation in 3, Haematological Malignancies 2, GI Malignancies 3, Connective tissues disorders 3, Nutritional iron deficiency 8 and Anaemia of chronic diseases in remaining cases. Among the 22 cases having macrocytic anaemia, 11 had vitamin B 12 deficiency, 6 had subclinical hypothyroidism, 5 had alcoholism. Among the 20 patients having normocytic normochromic blood picture, 4 had haemolytic anaemia, 1 had aplastic anaemia and remaining were having anaemia of chronic disease mainly chronic kidney disease. Regarding treatment, 23 patients were transfused blood. Out of total 100 patients included in the study, in-hospital mortality was 10. CONCLUSIONS Anaemia is associated with a variety of diseases. As Tuberculosis and B 12 Deficiency are among the leading causes of anaemia, hypochromic and microcytic picture was the predominant picture in peripheral blood smear. Among the patients having normocytic normochromic blood picture, majority were having chronic kidney disease which may be due to the fact that our hospital is a tertiary referral centre for chronic renal failure. In-hospital mortality due to anaemia alone is lower in tertiary care centres, but the mortality in our study is due to associated comorbid conditions like chronic renal failure and malignancy.

Malaria continues to be a global health challenge, affecting more than half the world's population and causing approximately 660,000 deaths annually. The majority of malaria cases are caused by Plasmodium falciparum and occur in sub-Saharan Africa. One of the major complications asscociated with malaria is severe anaemia, caused by a cycle of haemoglobin digestion by the parasite. Anaemia due to falciparum malaria in children has multifactorial pathogenesis, which includes suppression of bone marrow activity. Recent studies have shown that haemozoin, which is a by-product of parasite haemoglobin digestion, may play an important role in suppression of haemoglobin production, leading to anaemia. In this study we correlated the levels of erythropoietin (EPO), as an indicator of stimulation of haemoglobin production, to the levels of monocyte acquired haemozoin in children with both severe and uncomplicated malaria. There was a significantly negative correlation between levels of haemozoin-containing monocytes and EPO, which may suggest that haemozoin suppresses erythropoiesis in severe malaria. A multiple linear regression analysis and simple bar was used to investigate associations between various haematological parameters. To examine the levels of erythropoietin in the age categories, the levels of erythropoietin was measured using a commercial Enyme-Linked Immunosorbent Assay (ELISA). Giemsa-stained blood smears were used to determine percentage pigment containing monocytes. The haemozoin containing monocytes was expressed as a percentage of the total number of monocytes. To obtain the number of haemozoin containing monocytes/μL the percentage of haemozoin containing monocytes was multiplied by the absolute number of monocytes/μL from the automated haematology analyzer. The levels of erythropoietin in younger children (<3 years) was significantly higher than in older children with a similar degree of malaria anaemia (Hb levels) (p < 0.005). Haemozoin

Clonal hematopoiesis in acquired aplastic anemia.

Ogawa, Seishi

2016-07-21

Clonal hematopoiesis (CH) in aplastic anemia (AA) has been closely linked to the evolution of late clonal disorders, including paroxysmal nocturnal hemoglobinuria and myelodysplastic syndromes (MDS)/acute myeloid leukemia (AML), which are common complications after successful immunosuppressive therapy (IST). With the advent of high-throughput sequencing of recent years, the molecular aspect of CH in AA has been clarified by comprehensive detection of somatic mutations that drive clonal evolution. Genetic abnormalities are found in ∼50% of patients with AA and, except for PIGA mutations and copy-neutral loss-of-heterozygosity, or uniparental disomy (UPD) in 6p (6pUPD), are most frequently represented by mutations involving genes commonly mutated in myeloid malignancies, including DNMT3A, ASXL1, and BCOR/BCORL1 Mutations exhibit distinct chronological profiles and clinical impacts. BCOR/BCORL1 and PIGA mutations tend to disappear or show stable clone size and predict a better response to IST and a significantly better clinical outcome compared with mutations in DNMT3A, ASXL1, and other genes, which are likely to increase their clone size, are associated with a faster progression to MDS/AML, and predict an unfavorable survival. High frequency of 6pUPD and overrepresentation of PIGA and BCOR/BCORL1 mutations are unique to AA, suggesting the role of autoimmunity in clonal selection. By contrast, DNMT3A and ASXL1 mutations, also commonly seen in CH in the general population, indicate a close link to CH in the aged bone marrow, in terms of the mechanism for selection. Detection and close monitoring of somatic mutations/evolution may help with prediction and diagnosis of clonal evolution of MDS/AML and better management of patients with AA. © 2016 by The American Society of Hematology.

Genetic Associations in Acquired Immune-Mediated Bone Marrow Failure Syndromes: Insights in Aplastic Anemia and Chronic Idiopathic Neutropenia

Mavroudi, Irene; Papadaki, Helen A.

2012-01-01

Increasing interest on the field of autoimmune diseases has unveiled a plethora of genetic factors that predispose to these diseases. However, in immune-mediated bone marrow failure syndromes, such as acquired aplastic anemia and chronic idiopathic neutropenia, in which the pathophysiology results from a myelosuppressive bone marrow microenvironment mainly due to the presence of activated T lymphocytes, leading to the accelerated apoptotic death of the hematopoietic stem and progenitor cells, such genetic associations have been very limited. Various alleles and haplotypes of human leucocyte antigen (HLA) molecules have been implicated in the predisposition of developing the above diseases, as well as polymorphisms of inhibitory cytokines such as interferon-γ, tumor necrosis factor-α, and transforming growth factor-β1 along with polymorphisms on molecules of the immune system including the T-bet transcription factor and signal transducers and activators of transcription. In some cases, specific polymorphisms have been implicated in the outcome of treatment on those patients. PMID:22956967

Acquired aplastic anemia (aAA) is a nonmalignant disease caused by autoimmune destruction of early hematopoietic cells. Clonal hematopoiesis is a late complication, seen in 20-25% of older patients. We hypothesized that clonal hematopoiesis in aAA is a more general phenomenon, which can arise early in disease, even in younger patients. To evaluate clonal hematopoiesis in aAA, we used comparative whole exome sequencing of paired bone marrow and skin samples in 22 patients. We found somatic mutations in 16 patients (72.7%) with a median disease duration of 1 year; of these, 12 (66.7%) were patients with pediatric-onset aAA. Fifty-eight mutations in 51 unique genes were found primarily in pathways of immunity and transcriptional regulation. Most frequently mutated was PIGA, with seven mutations. Only two mutations were in genes recurrently mutated in myelodysplastic syndrome. Two patients had oligoclonal loss of the HLA alleles, linking immune escape to clone emergence. Two patients had activating mutations in key signaling pathways (STAT5B (p.N642H) and CAMK2G (p.T306M)). Our results suggest that clonal hematopoiesis in aAA is common, with two mechanisms emerging-immune escape and increased proliferation. Our findings expand conceptual understanding of this nonneoplastic blood disorder. Future prospective studies of clonal hematopoiesis in aAA will be critical for understanding outcomes and for designing personalized treatment strategies. Copyright © 2015 Elsevier Inc.

A plastic anemia is a rare life-threatening disease. However, since the introduction of immunosuppressive therapy and allogeneic stem cell transplantation, the outcome has improved considerably, and the 5-year survival is reported to be 70-80% in selected patient cohorts. Yet, contemporary population-based data on incidence and survival are lacking. We performed a national retrospective study to determine the incidence, treatment, and survival of patients with aplastic anemia diagnosed in Sweden from 2000-2011. Patients were included via the National Patient Registry, and diagnosed according to the Camitta criteria. In total, 257 confirmed cases were identified, with an overall incidence of 2.35 (95% CI: 2.06-2.64) cases per million inhabitants per year. Median age was 60 years (range: 2-92), and median follow up was 76 (0-193) months. Primary treatments included immunosuppressive therapy (63%), allogenic stem cell transplantation (10%), or single-agent cyclosporine/no specific therapy (27%). The 5-year survival was 90.7% in patients aged 0-18 years, 90.5% in patients aged 19-39 years, 70.7% in patients aged 40-59 years, and 38.1% in patients aged ≥60 years. Multivariate analysis showed that age (both 40-59 and ≥60 age groups), very severe aplastic anemia and single-agent cyclosporine/no specific therapy were independent risk factors for inferior survival. In conclusion, younger aplastic anemia patients experience a very good long-term survival, while that of patients ≥60 years in particular remains poor. Apparently, the challenge today is to improve the management of older aplastic anemia patients, and prospective studies to address this medical need are warranted.

Among the Japanese radiological technicians, four deaths from aplastic anemia have been reported after 1930. On the other hand, during the period from 1930 to 1960, the population of radiological technicians is estimated to be 74,400 man-years, in which 0.5 aplastic anemias are expected. However, actually three died from aplastic anemia. This difference is statistically significant at the 1% level. While, in the period from 1961 to 1973, the observed value is 1 against 0.7 expected. It is concluded that aplastic anemia had been induced frequently among the Japanese radiological technicians in the era when there was much exposure to occupational radiation. (orig.) [de

The clinical and histopathological distinctions between inherited versus acquired bone marrow failure and myelodysplastic syndromes are challenging. The identification of inherited bone marrow failure/myelodysplastic syndromes is critical to inform appropriate clinical management. To investigate whether a subset of pediatric and young adults undergoing transplant for aplastic anemia or myelodysplastic syndrome have germline mutations in bone marrow failure/myelodysplastic syndrome genes, we performed a targeted genetic screen of samples obtained between 1990–2012 from children and young adults with aplastic anemia or myelodysplastic syndrome transplanted at the Fred Hutchinson Cancer Research Center. Mutations in inherited bone marrow failure/myelodysplastic syndrome genes were found in 5.1% (5/98) of aplastic anemia patients and 13.6% (15/110) of myelodysplastic syndrome patients. While the majority of mutations were constitutional, a RUNX1 mutation present in the peripheral blood at a 51% variant allele fraction was confirmed to be somatically acquired in one myelodysplastic syndrome patient. This highlights the importance of distinguishing germline versus somatic mutations by sequencing DNA from a second tissue or from parents. Pathological mutations were present in DKC1, MPL, and TP53 among the aplastic anemia cohort, and in FANCA, GATA2, MPL, RTEL1, RUNX1, SBDS, TERT, TINF2, and TP53 among the myelodysplastic syndrome cohort. Family history or physical examination failed to reliably predict the presence of germline mutations. This study shows that while any single specific bone marrow failure/myelodysplastic syndrome genetic disorder is rare, screening for these disorders in aggregate identifies a significant subset of patients with inherited bone marrow failure/myelodysplastic syndrome.

The relationship between radiation exposure and aplastic anemia, clarified previously, is discussed. When persons such as radiological technicians receive whole-body irradiation in rather large doses, it is possible that aplastic anemia will result later on. However, this is difficult to determine because the irradiated region is limited despite large doses of radiation. (Bell, E.)

Whether the incidence of aplastic anemia significantly increases due to the later effect of atomic-bomb radiation was studied. After the data of aplastic anemia which occurred within 1950 - 1973 were evaluated and the diagnoses of the cases were certified, the incidence of aplastic anemia per 109,000 inhabitants of the cities of Hiroshima and Nagasaki was calculated and compared according to the dose of atomic-bomb radiation. There was no increase in the incidence according to an increase in radiation dose, and there was no fact that aplastic anemia increased in a certain period either. Most of the atomic-bomb survivors who were close to the epicenter and were clinically diagnosed as aplastic anemia had leukemia lesion or myeloid proliferating lesion, and it is likely to be that pathological changes resembling aplastic anemia may appear in a certain phase of myeloid proliferation or as a phenotype of myeloid proliferation. An evaluation was made on cases of aplastic anemia of other groups, but the doses of atomic-bomb radiation which they received were not so much to give effect on the bone marrow except only two cases.

Acquired aplastic anemia is a potentially fatal bone marrow failure disorder that is characterized by pancytopenia and a hypocellular bone marrow. Hematopoietic stem-cell transplantation or bone marrow transplantation (BMT) is the treatment of choice for young patients who have a matched sibling donor. Immunosuppression with either anti-thymocyte globulin and cyclosporine or high-dose cyclophosphamide is an effective therapy for patients who are not suitable BMT candidates owing to age or lack of a suitable donor. Results of BMT from unrelated and mismatched donors are improving, but presently this treatment option is best reserved for those patients who do not respond, relapse or develop secondary clonal disorders following immunosuppressive therapy. Efforts are currently underway to both improve immunosuppressive regimens and to expand the application of BMT. PMID:21495931

Rabbit antithymocyte globulin (rATG; thymoglobulin, Genzyme) in combination with cyclosporine, as first-line immunosuppressive therapy, was evaluated prospectively in a multicenter, European, phase 2 pilot study, in 35 patients with aplastic anemia. Results were compared with 105 age- and disease severity-matched patients from the European Blood and Marrow Transplant registry, treated with horse ATG (hATG; lymphoglobulin) and cyclosporine. The primary end point was response at 6 months. At 3 months, no patients had achieved a complete response to rATG. Partial response occurred in 11 (34%). At 6 months, complete response rate was 3% and partial response rate 37%. There were 10 deaths after rATG (28.5%) and 1 after subsequent HSCT. Infections were the main cause of death in 9 of 10 patients. The best response rate was 60% for rATG and 67% for hATG. For rATG, overall survival at 2 years was 68%, compared with 86% for hATG (P = .009). Transplant-free survival was 52% for rATG and 76% for hATG (P = .002). On multivariate analysis, rATG (hazard ratio = 3.9, P = .003) and age more than 37 years (hazard ratio = 4.7, P = .0008) were independent adverse risk factors for survival. This study was registered at www.clinicaltrials.gov as NCT00471848.

The current treatment approach for severe aplastic anemia in children is based on studies performed in the 1980s, and updated evidence is required. We retrospectively compared the outcomes of children with acquired severe aplastic anemia who received immunosuppressive therapy within prospective trials conducted by the Japanese Childhood Aplastic Anemia Study Group or who underwent bone marrow transplantation from an HLA-matched family donor registered in the Japanese Society for Hematopoietic Cell Transplantation Registry. Between 1992 and 2009, 599 children (younger than 17 years) with severe aplastic anemia received a bone marrow transplant from an HLA-matched family donor (n=213) or immunosuppressive therapy (n=386) as first-line treatment. While the overall survival did not differ between patients treated with immunosuppressive therapy or bone marrow transplantation [88% (95% confidence interval: 86-90) versus 92% (90-94)], failure-free survival was significantly inferior in patients receiving immunosuppressive therapy than in those undergoing bone marrow transplantation [56% (54-59) versus 87% (85-90); Paplastic anemia.

Acquired aplastic anemia (aAA) results from the T cell-mediated autoimmune destruction of hematopoietic stem cells. Factors predicting response to immune suppression therapy (IST) or development of myelodysplastic syndrome (MDS) are beginning to be elucidated. Our recent data suggest most patients with aAA treated with IST develop clonal somatic genetic alterations in hematopoietic cells. One frequent acquired abnormality is copy-number neutral loss of heterozygosity on chromosome 6p (6p CN-LOH) involving the human leukocyte antigen (HLA) locus. We hypothesized that because 6p CN-LOH clones may arise from selective pressure to escape immune surveillance through deletion of HLA alleles, the development of 6p CN-LOH may affect response to IST. We used single nucleotide polymorphism array genotyping and targeted next-generation sequencing of HLA alleles to assess frequency of 6p CN-LOH, identity of HLA alleles lost through 6p CN-LOH, and impact of 6p CN-LOH on response to IST. 6p CN-LOH clones were present in 11.3% of patients, remained stable over time, and were not associated with development of MDS-defining cytogenetic abnormalities. Notably, no patient with 6p CN-LOH treated with IST achieved a complete response. In summary, clonal 6p CN-LOH in aAA defines a unique subgroup of patients that may provide insights into hematopoietic clonal evolution. PMID:26702937

Aplastic anemia is a rare hematopoietic stem-cell disorder that results in pancytopenia and hypocellular bone marrow. Women with aplastic anemia usually are at increased risk of corpus luteum rupture due to thrombocytopenia and infection. Here we report two cases had hemoperitoneum from corpus luteum rupture in patients with aplastic anemia in our center. Case 1 involved two episodes of hemoperitoneum resulting from rupture of the corpus luteum in a 23-year-old unmarried female with severe aplastic anemia. This patient was managed conservatively with platelet and packed red cell transfusion. Case 2 involved two episodes of hemoperitoneum resulting from rupture of the corpus luteum in a 33-year-old married patient with aplastic anemia. Emergency laparoscopy revealed massive hemoperitoneum. Bilateral salpingo-oophorectomy were performed successively with platelet and packed red cell transfusion. Hemoperitoneum resulting from a ruptured corpus luteum is a life-threatening condition in patients with aplastic anemia. Prompt and appropriate evaluation of corpus luteum rupture and emergent therapy are needed.

To evaluate the association between organophosphorus pesticides and aplastic anemia, and provide scientific evidence for the primary prevention of aplastic anemia. The published papers of case control studies on the association between organophosphorus pesticides and aplastic anemia from January 1990 to August 2014 were collected from Chinese BioMedical Literature Base (CBM), Chinese National Knowledge Infrastructure (CNKI), PubMed and EMBASE. The papers which met the inclusion criteria were evaluated. The pooled odds ratios (OR) and 95% confidence interval (CI) of organophosphorus pesticides were calculated with software Review Manager 5.0. Subgroup analysis were conducted for different population and different usage of organophosphorus pesticides. A total of 9 papers were selected, involving 5 833 subjects (1 404 cases and 4 429 controls). The results showed that organophosphorus pesticides could increase the risk of aplastic anemia (OR=1.97, 95% CI: 1.60-2.44) . Subgroup analysis showed that Asian (OR=2.01, 95% CI: 1.52-2.66) had higher risk of aplastic anemia than American or European (OR=1.93, 95% CI: 1.39-2.67) . Using pure organophosphorus pesticides (OR=2.15, 95% CI: 1.60-2.88) was more prone to cause aplastic anemia than using the mixture of organophosphorus pesticides (OR=1.82, 95% CI: 1.34-2.47). The analysis indicated that organophosphorus pesticides might be a risk factor for aplastic anemia. Reducing organophosphorus pesticides exposure in daily life and industrial or agricultural production could prevent the incidence of aplastic anemia.

Chicken infectious anaemia (CIA) is a disease with a highly economic impact in the poultry industry. The infected chickens are characterized by aplastic anaemia and extreme immunosuppression, followed by the increased susceptibility to secondary infectious pathogens and suboptimal immune responses for vaccination. Commercially available CIA vaccines are routinely used in the breeders in Taiwan to protect their progeny with maternal-derived antibodies. However, CIA cases still occur in the field and little is known about the genetic characteristics of Taiwanese chicken anaemia viruses (CAVs). In this study, CAV DNA was detected in 72 of 137 flocks collected during 2010-2015. Among the PCR-positive samples, the coding regions of 51 CAVs were sequenced. Phylogenetic analysis of the VP1 gene revealed that, although most of Taiwanese CAVs belonged to genotypes II and III, some isolates were clustered into a novel genotype (genotype IV). Moreover, a Taiwanese isolate in this novel genotype IV appeared to be derived from a recombination event between genotypes II and III viruses. Five Taiwanese CAV isolates were highly similar to the vaccine strains, 26P4 or Del-Ros. Taken together, these results indicate that the sequences of CAVs in Taiwan are variable, and inter-genotypic recombination had occurred between viruses of different genotypes. Moreover, vaccine-like strains might induce clinical signs of CIA in chickens. Our findings could be useful for understanding the evolution of CAVs and development of a better control strategy for CIA. © 2018 Blackwell Verlag GmbH.

Some epidemiological inferences on possibility of induction of aplastic anemia following radiotherapy are tried. In Japan after 1969, there are detected and reported 11 cases of radiation-related aplastic anemia after radiotherapy diagnosed by hematologists. Of 11 cases, 2 are males and 9 are females, ranging 28 to 66 years of age. All these patients were irradiated for malignant diseases. The population at risk after 1969 was estimated to be 674, 660 man-years, based on the additional survey on number and survival rate of patients irradiated. The expected value of aplastic anemia calculated from this population at risk is 10.2, against 11 cases observed above-described. There is no statistically significant difference. Namely, there is no epidemiological evidence that aplastic anemia is induced by local-body irradiation such as radiotherapy. (auth.)

Isolated acquired factor VII deficiency is a rare coagulopathy. It has been reported in 31 patients with malignancy, sepsis, postoperatively, aplastic anemia, and during bone marrow transplantation. We discuss, through a new case of acquired factor VII deficiency, the characteristics of this disease when it is associated with acute myeloid leukemia. Acquired factor VII deficiency in hematological diseases can be caused by intensive chemotherapy, infections, or hepatic dysfunction. The best treatment in developing countries remains corticosteroids associated with plasma exchange, frozen plasma, and antibiotics.

Unrelated allogeneic transplantation for severe aplastic anemia is a treatment option after immunosuppressive treatment failure in the absence of a matched sibling donor. Age, delay between disease diagnosis and transplantation, and HLA matching are the key factors in transplantation decisions, but their combined impact on patient outcomes remains unclear. Using the French Society of Bone Marrow Transplantation and Cell Therapies registry, we analyzed all consecutive patients (n=139) who underwent a first allogeneic transplantation for idiopathic severe aplastic anemia from an unrelated donor between 2000 and 2012. In an adjusted multivariate model, age over 30 years (Hazard Ratio=2.39; P=0.011), time from diagnosis to transplantation over 12 months (Hazard Ratio=2.18; P=0.027) and the use of a 9/10 mismatched unrelated donor (Hazard Ratio=2.14; P=0.036) were independent risk factors that significantly worsened overall survival. Accordingly, we built a predictive score using these three parameters, considering patients at low (zero or one risk factors, n=94) or high (two or three risk factors, n=45) risk. High-risk patients had significantly shorter survival (Hazard Ratio=3.04; Paplastic anemia. Copyright© Ferrata Storti Foundation.

Acquired aplastic anemia(aAA is a severe and rare disease, characterized by hematopoietic bone marrow failure and peripheral cytopenia. The pathophysiology is immune mediated in most cases, activated T1 lymphocytes have been identified as effector cells . The disease can be successfully treated with combined immunosuppressive therapy or allogeneic hematopoietic stem cell transplantation.

Hepatitis-associated aplastic anemia (HAA  is a syndrome of bone marrow failure following the development of acute seronegative hepatitis. HAA syndrome most often affects young males who presented severe pancytopenia two to three months after an episode of acute hepatitis. The clinical course of hepatitis is more frequently benign but a fulminant severe course is also described. The bone marrow failure can be explosive and severe and it is usually fatal if untreated, no correlations have been observed between severity of hepatitis and AA.

In none of the  studies a specific virus could be identified and most cases are seronegative for known hepatitis viruses. The clinical characteristics  and response to immunotherapy indicate a central role for immune-mediated mechanism in the pathogenesis of HAA. The initial

MR imaging of the femoral bone marrow was performed in 12 patients with untreated aplastic anemia and six patients with hypoplastic myelodysplastic syndrome (MDS). The MRI appearance was classified into four patterns; fatty marrow faint signal, nodular pattern and heterogeneous infiltration. The MRI patterns of aplastic anemia were evaluated and compared with those of hypoplastic MDS. In spite of hypocellular biopsies, MRI of the femoral marrow showed unexpected abnormal signal intensities in aplastic anemia; nodular pattern in five and heterogeneous infiltration pattern in two patients. Completely fatty marrow was depicted in four patients mainly with severe aplastic anemia. The nodular pattern with a background of fatty marrow was commonly seen in moderate or severe cases, while the heterogeneous infiltration pattern was noted in mild cases of the disease. Compared with hypoplastic MDS, asymmetrical nodular pattern suggesting patchy hematopoiesis was thought to be a characteristic finding of aplastic anemia. One patient clinically diagnosed as aplastic anemia, who had shown heterogeneous infiltration pattern, evolved to acute myeloid leukemia. We concluded that MRI of the femoral marrow could be useful in the assessment of aplastic anemia and detection of myelodysplastic or leukemic transformation. (author).

Aplastic anemia (AA) is a disease characterized by pancytopenia and hypoplastic bone marrow caused by the decrease of hematopoietic stem cells. The pathogenesis of AA is complex and involves an abnormal hematopoietic microenvironment, hematopoietic stem cell/progenitor cell deficiencies and immunity disorders. Survival in severe aplastic anemia (SAA) has markedly improved in the past 4 decades because of advances in hematopoietic stem cell transplantation, immunosuppressive and biologic drugs, and supportive care. Herein, we will update the main issues concern AA according to our literature review. Copyright © 2014 Elsevier B.V. All rights reserved.

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 (P<0.001). The combined absence of a minor paroxysmal nocturnal hemoglobinuria population and a short telomere 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.

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. © 2015 S. Karger AG, Basel.

Aplastic anemia therapy remains difficult, due to lack of effective treatment regimens. In recent years, Huangqi injection for the adjunctive therapy of aplastic anemia has been reported in many clinical trials. Considering that Huangqi injection may be a novel approach to aplastic anemia treatment, we conducted a meta-analysis of clinical controlled trials to assess the clinical value of Huangqi injection in the treatment of aplastic anemia. We searched the Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Chinese Scientific Journals Full-text Database (VIP), Wanfang Database, PubMed and EMBASE database to collect the data about the trials of Huangqi injection combined with androgens for treating aplastic anemia. A total of ten studies involving 720 patients with aplastic anemia were included in this study. The meta-analysis showed significant increases in the pool effectiveness rate, white blood cells (WBC), haematoglobin (Hb), platelets (PLT), and reticulocytes (Ret) between the experimental group versus the control group. No severe side effects were found in this study. However, the lower Jadad scores and asymmetric funnel plot degrades the validity of the meta-analysis as the clinical evidence. Therefore, Huangqi injection may significantly enhance the efficacy of androgens for aplastic anemia, suggesting that the novel approach of Chinese traditional medicine combined with Western medicine is promising. The exact outcome required confirmation with rigorously well-designed multi-center trials. PMID:26379817

Background: Iron deficiency anaemia and anaemia of chronic disorders are the two major causes of microcytic and hypochromic anaemia. Many times the diagnosis of these conditions becomes difficult through conventional laboratory tests. Determination of soluble transferrin receptors is a helpful laboratory test for the differential diagnosis of these conditions. The study was conducted to evaluate the role of soluble transferrin receptors in the differential diagnosis between iron deficiency anaemia and anaemia of chronic disorders. Methods: A total of 80 blood samples were evaluated, i.e., 20 samples from normal adult male, 20 samples from normal adult female, 20 samples from iron deficiency anaemia group and 20 samples from patients with anaemia of chronic disorders. Soluble transferrin receptors were determined by ELISA technique using Quantikine IVD kit (R and D Systems). Results: There was significant difference in the levels of sTfR in iron deficiency anaemia and anaemia of chronic disorders. Statistically non-significant difference was observed between the levels of sTfR in patients with anaemia of chronic disorders as compared to normal control group. Conclusion: The sTfR determination can be used as a reliable differentiating marker in the diagnosis of iron deficiency anaemia and anaemia of chronic disorders. (author)

To explore the clinical characteristic, therapeutic efficacy and prognosis of patients with hepatitis-associated aplasitc anemia (HAAA). the clinical data and labrotatory examination results of 30 cases of HAAA were analyzed retrospectively, the 6-month response ratio and overall survival (OS) were assessed. HAAA most commonly occured in males, with the occurence rate of males and females was 4:1, the median onset age was 16 (4-43) years old, HAAA oriented focus on sever aplastic anemia (SAA)(4 cases,13%) and very sever aplastic anemia (VSAA)(22 cases,73%). Aplastic anemia (AA) could be seen on occurence of hepatitis (accompanied aplastic anemia) (7 cases,23%), or after the onset of hepatits (delayed aplastic anemia) (23 cases,77%), but more often occured in the latter. Statistical analysis showed that when compared with the patients of delayed aplastic anemia, patients accompanied aplastic anemia possesses lower levels of glutamic-pyruvic transaminase(ALT), aspertate aminotransferase (AST) and total bilirubin (TBIL)(P=0.042,0.012,0.001), and possessed a more obvious lymphoid cell disorder when AA occured, with more lower peripheral blood CD19 + B cells proportion (P=0.046) and more obvious imbalance of CD4 + /CD8 + ratio, but the difference was no statistical significant (P=0538). Factors affecting the 6-month respose were the severity of AA (P=0.044), the peak level of bilirubin of hepatitis (P=0.006) and the propotion of mature monocyte in bone marrow (P=0.034). The long-term follow-up showed that the 2-year OS of HAAA was 64.3±9.2%, the 6-month curative efficacy significantly affect the prognosis (Paplastic anemia, patients usually have a high incidence of early infection. Patients acompanied with aplastic anemia possess more obvious immunological derangement; the treatment efficacy for HAAA is poor, patients who haven't obtained 6-month response indicate a sinister prognosis, allogeneic hematopoietic stem cell transplantion is a better choice for these

Aplastic anemia is a syndrome in which hematopoietic stem cells are decreased and bone marrow hypoplasia and pancytopenia are observed; it is considered as a T cell-mediated autoimmune disease. Recently, it has been reported that gene mutations suggestive of clonal hematopoiesis are detected in approximately one third of the patients with aplastic anemia. Among treatment approaches other than hematopoietic stem cell transplantation, immunosuppressive therapy with antithymocyte globulin (ATG) plus cyclosporin is a basic approach, although it has been shown that eltrombopag, a thrombopoietin receptor agonist, is effective and that the recovery of hematopoiesis in three blood lineage is observed in some patients. Studies on the optimum dose of ATG are in progress. Regarding hematopoietic stem cell transplantation for aplastic anemia, regimens are being designed in which cyclophosphamide as a pretreatment is reduced and fludarabine is instead used in combination for the reduction of cardiotoxicity. Because HLA haploidentical transplantation has been developed and its reports are increasing for patients who cannot find appropriate donors, transplantation may be possible in patients who had previously given up on it.

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

Background Associations between aplastic anemia and numerous drugs, pesticides and chemicals have been reported. However, at least 50% of the etiology of aplastic anemia remains unexplained. Design and Methods This was a case-control, multicenter, multinational study, designed to identify risk factors for agranulocytosis and aplastic anemia. The cases were patients with diagnosis of aplastic anemia confirmed through biopsy or bone marrow aspiration, selected through an active search of clinical laboratories, hematology clinics and medical records. The controls did not have either aplastic anemia or chronic diseases. A total of 224 patients with aplastic anemia were included in the study, each case was paired with four controls, according to sex, age group, and hospital where the case was first seen. Information was collected on demographic data, medical history, laboratory tests, medications, and other potential risk factors prior to diagnosis. Results The incidence of aplastic anemia was 1.6 cases per million per year. Higher rates of benzene exposure (≥30 exposures per year) were associated with a greater risk of aplastic anemia (odds ratio, OR: 4.2; 95% confidence interval, CI: 1.82–9.82). Individuals exposed to chloramphenicol in the previous year had an adjusted OR for aplastic anemia of 8.7 (CI: 0.87–87.93) and those exposed to azithromycin had an adjusted OR of 11.02 (CI 1.14–108.02). Conclusions The incidence of aplastic anemia in Latin America countries is low. Although the research study centers had a high coverage of health services, the underreporting of cases of aplastic anemia in selected regions can be discussed. Frequent exposure to benzene-based products increases the risk for aplastic anemia. Few associations with specific drugs were found, and it is likely that some of these were due to chance alone.

Hematopoietic Acute Radiation Syndrome (Bone marrow syndrome, Aplastic Anemia): Molecular Mechanisms of Radiation Toxicity.

Science.gov (United States)

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.

A large number of patients diagnosed with bone marrow failure syndromes (BMFS), comprising aplastic anaemia (AA) and myelodysplastic syndromes (MDS), remain aetiologically uncharacterized worldover, especially in resource constrained set up. We carried out this study to identify a few constitutional causes in BMFS patients attending a tertiary care hospital in north India. Peripheral blood lymphocyte cultures were performed (with and without clastogens) in a cohort of 135 consecutive BMFS patients, in order to detect Fanconi anaemia (FA), Down's syndrome (+21), trisomy 8 (+8) and monosomy 7 (-7). Constitutional factors were detected in 17 (12.6%) patients. FA defect was observed in 24.07 percent (13/54), 16.66 percent (1/6) and 2.85 percent (1/35) paediatric aplastic anaemia, paediatric MDS and adult MDS patients respectively. Down's syndrome was detected in 5.00 percent (2/40) adult aplastic anaemia patients. None of the patients revealed trisomy 8 or monosomy 7. Presence of an underlying factor determines appropriate management, prognostication, family screening and genetic counselling of BMFS patients. Special tests required to confirm or exclude constitutional aetiological factors are not available to majority of the patients in our country. Diepoxybutane (DEB) test yielded better results than mitomycin C (MMC) test in our experience.

Direct interactions of the five known Fanconi anaemia proteins suggest a common functional pathway.

Fanconi anaemia (FA) is an autosomal recessive inherited disorder associated with a progressive aplastic anaemia, diverse congenital abnormalities and cancer. The condition is genetically heterogeneous, with at least seven complementation groups (A-G) described. Cells from individuals who are homozygous for mutations in FA genes are characterized by chromosomal instability and hypersensitivity to DNA interstrand crosslinking agents. These features suggest a possible role for the encoded proteins in the recognition or repair of these lesions, but neither their function nor whether they operate in a concerted or discrete functional pathways is known. The recent cloning of the FANCF and FANCE genes has allowed us to investigate the interaction of the proteins encoded by five of the seven complementation groups of FA. We used the yeast two-hybrid system and co-immunoprecipitation analysis to test the 10 possible pairs of proteins for direct interaction. In addition to the previously described binding of FANCA to FANCG, we now demonstrate direct interaction of FANCF with FANCG, of FANCC with FANCE and a weaker interaction of FANCE with both FANCA and FANCG. These findings show that the newly identified FANCE protein is an integral part of the FA pathway, and support the concept of a functional link between all known proteins encoded by the genes that are mutated in this disorder. These proteins may act either as a multimeric complex or by sequential recruitment of subsets of the proteins in a common pathway that protects the genomic integrity of mammalian cells.

Graft failure and survival are the major problems for patients with aplastic anemia undergoing hematopoietic stem cell transplantation (HSCT). Previous studies showed that anti-HLA antibodies negatively impact engraftment in HSCT. This retrospective study of 51 pediatric patients with acquired aplastic anemia who underwent allogeneic HSCT at a single institution between 2006 and 2012 investigated the influence of anti-HLA antibodies on the outcome of HSCT. Serum samples collected before HSCT were tested for the presence of anti-HLA antibodies. Pre-existing anti-HLA antibodies were detected in 54.9% (28/51) of patients, among whom 39.2% (20/51) had anti-HLA class I antibodies. Anti-HLA antibodies were associated with worse five-yr survival (78.6% vs. 100%, p = 0.021) and higher treatment-related mortality (21.4% vs. 0%, p = 0.028) compared with antibody-negative patients. Anti-HLA class I antibody-positive patients had poorer five-yr survival (75.0%) than anti-HLA class I&II antibody-positive and antibody-negative patients (87.5% and 100.0%, respectively, p = 0.039). Presence of anti-HLA class I antibodies (p = 0.024) and older age (10 yr or more; p = 0.027) significantly increased the risk of post-HSCT mortality. Pre-existing anti-HLA antibodies negatively affect the outcome of HSCT in pediatric patients with aplastic anemia. Routine testing for anti-HLA antibodies concurrent with efficient treatment should be conducted prior to HSCT. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Evidence from randomized controlled trials has shown that delayed cord-clamping is beneficial to infant iron status. The role of maternal anaemia in this relationship, however, has not been established. To determine the effect of maternal anaemia at delivery on the association between timing of umbilical cord-clamping and infant anaemia at 4 and 8 months of age. A cohort of pregnant women admitted to the labour room of Hospital Iquitos (Iquitos, Peru) and their newborns were recruited into the study during two time periods (18 May to 3 June and 6-20 July 2009). Between the two recruitment periods, the hospital's policy changed from early to delayed umbilical cord-clamping. Maternal haemoglobin levels were measured before delivery, and the time between delivery and cord-clamping was recorded at delivery for the entire cohort. Mother-infant pairs were followed-up at 4 (n = 207) and 8 months (n = 184) post partum. Infant haemoglobin levels were measured at follow-up visits. Data were analysed using logistic regression models. The prevalence of maternal anaemia (Hb anaemia was modified by the mother's anaemia status. Significant benefits of delayed cord-clamping in preventing anaemia were found in infants born to anaemic mothers at both 4 months (aOR = 0.59, 95% CI 0.36-0.99) and 8 months (aOR = 0.38, 95% CI 0.19-0.76) of age. The study contributes additional evidence in support of delayed cord-clamping. This intervention is likely to have most public health impact in areas with a high prevalence of anaemia during pregnancy.

Personal experience is outlined with a preparative regimen consisting of total nodal irradiation (TNI) and cyclophosphamide in patients with severe aplastic anemia undergoing bone marrow transplantation (BMT). Nine patients (median age 23) previously having blood transfusions received BMT at the BMT Center in Pesaro. All patients were prepared for transplantation with cyclophosphamide 50 mg/kg/day (day -6, -5, -4, -3), and 7,5 Gy total nodal irradiation day -1, with a dose rate of 26 cGy/m. Six out of eight evaluable transplanted patients are still surviving 3 to 23 months with a median follow-up of 16,5 months. This preoperative regimen is extremely effective in decreasing rejection following transplantation for severe aplastic anemia. Future investigation must be aimed at the elimination of graft-versus-host-disease and control of fatal infections

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.

Incidence of aplastic anemia and agranulocytosis in Latin America: the LATIN study

Directory of Open Access Journals (Sweden)

Nelson Hamerschlak

Full Text Available CONTEXT AND OBJECTIVE: Aplastic anemia and agranulocytosis are rare but life-threatening disorders, often caused by drugs and other environmental exposures. Reported incidence of these diseases seems to vary between different geographic regions, and few data on their incidence are available for Latin American countries. The aim of this work is to determine the incidence of agranulocytosis and aplastic anemia in Brazil. DESIGN AND SETTING: Incidence study. Seven centers took part in the pilot phase, so as to represent all Brazilian regions. METHODS: Each center conducted an active search for new cases in a defined region by means of regular contacts with all hematologists, main clinical laboratories and clinicians in hospitals of the region. RESULTS: 74 patients with aplastic anemia and 16 with agranulocytosis were identified. Patients with agranulocytosis had a median age of 31 years (interquartile range, IQR: 12.5-48.2; 32.2% were male and 81.2% were white. The median age of aplastic anemia patients was 21 years (IQR 15.0-35.2; 62.2% were male, 50.0% were white and 39.2% mulatto. The incidence of agranulocytosis was estimated to be 0.5 cases per million individuals per year, ranging from 0.0 to 1.1 cases per million per year between regions. The incidence of aplastic anemia was 2.7 cases per million per year, ranging from 1.1 to 7.1 cases per million per year between regions. CONCLUSIONS: Aplastic anemia and agranulocytosis are rare diseases in Brazil. However, there is considerable variability in their incidences between different regions.

Few therapeutic options are available for patients with aplastic anemia who are ineligible for transplantation or refractory to immunosuppressive therapy. Eltrombopag was recently shown to produce trilineage responses in refractory patients. However, the effects of real-life use of this drug remain unknown. This retrospective study (2012-2016) was conducted by the French Reference Center for Aplastic Anemia on patients with relapsed/refractory aplastic anemia, and patients ineligible for antithymocyte globulin or transplantation, who received eltrombopag for at least 2 months. Forty-six patients with aplastic anemia were given eltrombopag without prior antithymocyte globulin treatment (n=11) or after antithymocyte globulin administration (n=35) in a relapsed/refractory setting. Eltrombopag (median daily dose 150 mg) was introduced 17 months (range, 8-50) after the diagnosis of aplastic anemia. At last followup, 49% were still receiving treatment, 9% had stopped due to a robust response, 2% due to toxicity and 40% due to eltrombopag failure. Before eltrombopag treatment, all patients received regular transfusions. The overall rates of red blood cell and platelet transfusion independence were 7%, 33%, 46% and 46% at 1, 3, 6 months and last follow-up. Responses were slower to develop in antithymocyte treatment-naïve patients. In patients achieving transfusion independence, hemoglobin concentration and platelet counts improved by 3 g/dL (interquartile range, 1.4-4.5) and 42×10 9 /L (interquartile range, 11-100), respectively. Response in at least one lineage (according to National Institutes of Health criteria) was observed in 64% of antithymocyte treatment-naïve and 74% of relapsed/refractory patients, while trilineage improvement was observed in 27% and 34%, respectively. We found high rates of hematologic improvement and transfusion independence in refractory aplastic anemia patients but also in patients ineligible for antithymocyte globulin receiving first

For the first time, we conducted a 2-center retrospective study to show the efficacy of antithymocyte globulin (ATG)-Fresenius S plus cyclosporine treatment of children with severe aplastic anemia. From March 1997 to May 2011, a total of 124 patients (median age, 7.5 y; range, 1.5 to 16 y) from 2 centers with acquired AA treated with an immunosuppressive therapy (IST) regimen, consisting of ATG-Fresenius S (5 mg/kg per day for 5 d) and cyclosporine, were enrolled. The response rate was 55.6%. The median time between IST and response was 6 (0.5 to 18) months. After a median follow-up time of 29 (6 to 153) months, the rates of relapse and clonal evolution were 3.2% and 0.8%, respectively. Overall, 17 patients (13.7%) died in this study: 14 resulted from sepsis, 1 resulted from intracranial hemorrhage, 1 occurred after hematopoietic stem cell transplantation, and 1 resulted from clonal disease progression. The 5-year overall survival rate for the entire cohort was 74.7%. IST responders had a better survival rate (100%) than nonresponders (70.7%). The use of ATG-Fresenius S plus cyclosporine as a first-line immunosuppressive treatment appeared to be effective for children with severe aplastic anemia in our study. ATG-Fresenius S could be another option in the treatment arsenal, especially in countries where the other ATG products are harder to acquire.

2012-02-01

Anaemia in pregnancy, defined as a haemoglobin concentration (Hb) anaemia in pregnancy, nutritional iron deficiency anaemia (IDA) being the commonest. Underlying inflammatory conditions, physiological haemodilution and several factors affecting Hb and iron status in pregnancy lead to difficulties in establishing a definitive diagnosis. IDA is associated with increased maternal and perinatal morbidity and mortality, and long-term adverse effects in the new born. Strategies to prevent anaemia in pregnancy and its adverse effects include treatment of underlying conditions, iron and folate supplementation given weekly for all menstruating women including adolescents and daily for women during pregnancy and the post partum period, and delayed clamping of the umbilical cord at delivery. Oral iron is preferable to intravenous therapy for treatment of IDA. B12 and folate deficiencies in pregnancy are rare and may be due to inadequate dietary intake with the latter being more common. These vitamins play an important role in embryo genesis and hence any relative deficiencies may result in congenital abnormalities. Finding the underlying cause are crucial to the management of these deficiencies. Haemolytic anaemias rare also rare in pregnancy, but may have life-threatening complications if the diagnosis is not made in good time and acted upon appropriately. Copyright © 2011 Elsevier Ltd.

Syngeneic peripheral blood stem cell transplantation with immunosuppression for hepatitis-associated severe aplastic anemia

Directory of Open Access Journals (Sweden)

Aleksandar Savic

2010-12-01

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.

In 90 patients with aplastic anemia who were seen at Dept. Med. RINMB, Hiroshima Univ. from 1962 to March, 1980, clinical findings of 33 A-bomb survivors (which included the second generation of the survivors) and those of 57 nonexposed patients were compared. No relationship was found between the age at the time of exposure and the period preceding onset of the disease. The A-bomb survivors showed higher neutrophil counts and higher reticulocyte counts than the nonexposed patients. There were less severe cases in the A-bomb survivors. There was no difference in the incidence of atypical aplastic anemia between the exposed patients and the nonexposed ones. No difference was found in overall survival (one-year and five-year survival rates) between the exposed and the nonexposed. The A-bomb survivors often had complete remission or maintenance of remission, and rarely had acute progression. These results suggested that clinical picture of aplastic anemia in the A-bomb survivors is different from that in the nonexposed patients.

The aim of this study was to evaluate the levels of interleukin (IL)-6 and IL-8 in patients with aplastic anemia and its correlation with severity of the disease. IL-6 and IL-8 levels were measured in 40 patients with aplastic anemia in the age group of 4 to 14 years. A total of 40 healthy children served as controls. Quantitative estimation of IL-6 and IL-8 was performed using a solid-phase sandwich ELISA kit. Results were presented as IL-6 and IL-8 concentrations in pg/mL. Patients received immunosuppressive therapy per the British Committee for Standards in Haematology Guidelines 2009. Mean age of the patients was 9.78±2.74 years. IL-6 level of patients was elevated compared with controls (193.48±352.3 vs. 4.58±3.39; Paplastic anemia (724.33±519.42), followed by severe aplastic anemia (80.51±66.28 pg/mL), and non-severe aplastic anemia (6.01±1.89). Differences were statistically significant. A similar trend was also observed for IL-8 levels, where the levels were 41.02±24.23, 11.34±8.0, and 1.67±0.71 for very severe aplastic anemia, severe aplastic anemia, and non-severe aplastic anemia, respectively. The differences were again statistically significant. IL levels were also correlated with the treatment outcome. Responders had lower levels compared with nonresponders, but the difference was not statistically significant (186.36±322.45 vs. 198.74±368.10). Levels of ILs decreased in responders, but were not comparable with that of controls 6 months after therapy. High levels of IL-6 and IL-8 were observed in children with aplastic anemia. Increased levels showed correlation with disease severity and therefore appear to play an important role in aplastic anemia. However, levels had no significant correlation with the treatment outcome.

Postpartum Aplastic Anemia Presenting as Pancytopenia Due to Malarial Infection

Pancytopenia is a condition with decreased numbers of all cell lines. Aplastic anemia is a common cause although malarial infection causing lysis of RBCs may also partly mimic this condition. The infection may also damage the patient's bone marrow resulting in pancytopenia as well. We present the case of a post-partum female patient who reported with fever, body aches and shortness of breath one month after the delivery of her baby. All blood cell counts were decreased and peripheral blood smear showed malarial parasites. Anti-malarial treatment was initiated following which the fever subsided but, despite regular transfusions, the blood counts remained low. Bone marrow biopsy report revealed P. falciparum pigments along with hypocellularity characteristic of severe aplastic anemia. Consequently, bone marrow transplantation was advised as a therapeutic measure. This case report highlights the increased susceptibility of pregnant women to malaria in endemic areas and subsequent aplastic anemia. (author)

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

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.

2015-06-01

Peripheral cytopenias are common in systemic lupus erythematosus, but bone marrow involvement is rarely reported. Aplastic anemia is the result of immune-mediated destruction of hematopoietic stem cells causing pancytopenia and characterized by an empty bone marrow. This rare but serious disease has been described as an unusual manifestation of systemic lupus erythematosus. We reviewed the 25 cases published in the English language literature and discuss the clinical presentation, outcome, treatment, and pathophysiology of aplastic anemia as a complication of systemic lupus erythematosus. We report here the first case of aplastic anemia associated with systemic lupus erythematosus treated with an allogeneic hematopoietic stem cell transplant. Over one half of patients received concomitantly the diagnoses of systemic lupus erythematosus and aplastic anemia. No clinical or histological features can distinguish primary aplastic anemia from aplastic anemia occurring in systemic lupus erythematosus patients. The overall mortality is about 15% and corticosteroid-based therapy alone or in combination with other immunomodulatory drugs can restore bone marrow function. Systemic lupus erythematosus may be complicated by bone marrow involvement. The diagnosis of peripheral cytopenias should be confirmed by bone marrow aspiration. All these patients should receive cortisone as a first treatment. Plasma exchanges seem to have some efficacy. Other different immunomodulatory therapies were used with variable results.

A proportion of patients with aplastic anemia who are treated with immunosuppressive therapy develop clonal hematologic disorders, including post-aplastic anemia myelodysplastic syndrome. Many will proceed to allogeneic hematopoietic stem cell transplantation. We identified 123 patients with post-aplastic anemia myelodysplastic syndrome who from 1991 through 2011 underwent allogeneic hematopoietic stem cell transplantation, and in a matched-pair analysis compared outcome to that in 393 patients with de novo myelodysplastic syndrome. There was no difference in overall survival. There were no significant differences with regard to 5-year probabilities of relapse, non-relapse mortality, relapse-free survival and overall survival; these were 14%, 40%, 46% and 49% for post-aplastic anemia myelodysplastic syndrome, and 20%, 33%, 47% and 49% for de novo myelodysplastic syndrome, respectively. In multivariate analysis, relapse (hazard ratio 0.71; P=0.18), non-relapse mortality (hazard ratio 1.28; P=0.18), relapse-free survival (hazard ratio 0.97; P=0.80) and overall survival (hazard ratio 1.02; P=0.88) of post-aplastic anemia myelodysplastic syndrome were similar to those of patients with de novo myelodysplastic syndrome. Cytogenetic risk was independently associated with overall survival in both groups. Thus, transplant success in patients with post-aplastic anemia myelodysplastic syndrome was similar to that in patients with de novo myelodysplastic syndrome, and cytogenetics was the only significant prognostic factor for post-aplastic anemia myelodysplastic syndrome patients.

This case report shows the clinical impact of a FDG-PET/CT in the assessment of bone marrow (BM) of a patient with aplastic anemia. The feasibility of a quantitative approach to BM intensities on FDG-PET is also discussed. In the authors' opinion, a deeper understanding of the factors that might independently affect FDG uptake and the definition of normal ranges of BM SUV (standardized uptake value) might help to interpret PET/CT images. Further research is needed to understand the physio-pathological basis of FDG uptake in BM and the potential value of its quantification. The analysis of the bone marrow on PET/CT is an interesting field of research. A PET/CT scan contributed to differential diagnosis in a patient with suspected bone marrow aplasia for guiding bone marrow biopsies.

Hepatitis Associated Aplastic Anemia: A review

Science.gov (United States)

2011-01-01

Hepatitis-associated aplastic anemia (HAAA) is an uncommon but distinct variant of aplastic anemia in which pancytopenia appears two to three months after an acute attack of hepatitis. HAAA occurs most frequently in young male children and is lethal if leave untreated. The etiology of this syndrome is proposed to be attributed to various hepatitis and non hepatitis viruses. Several hepatitis viruses such as HAV, HBV, HCV, HDV, HEV and HGV have been associated with this set of symptoms. Viruses other than the hepatitis viruses such as parvovirus B19, Cytomegalovirus, Epstein bar virus, Transfusion Transmitted virus (TTV) and non-A-E hepatitis virus (unknown viruses) has also been documented to develop the syndrome. Considerable evidences including the clinical features, severe imbalance of the T cell immune system and effective response to immunosuppressive therapy strongly present HAAA as an immune mediated mechanism. However, no association of HAAA has been found with blood transfusions, drugs and toxins. Besides hepatitis and non hepatitis viruses and immunopathogenesis phenomenon as causative agents of the disorder, telomerase mutation, a genetic factor has also been predisposed for the development of aplastic anemia. Diagnosis includes clinical manifestations, blood profiling, viral serological markers testing, immune functioning and bone marrow hypocellularity examination. Patients presenting the features of HAAA have been mostly treated with bone marrow or hematopoietic cell transplantation from HLA matched donor, and if not available then by immunosuppressive therapy. New therapeutic approaches involve the administration of steroids especially the glucocorticoids to augment the immunosuppressive therapy response. Pancytopenia following an episode of acute hepatitis response better to hematopoietic cell transplantation than immunosuppressive therapy. PMID:21352606

This is the clinical case of a primiparous eight month pregnant female, presenting with symptoms of pregnancy-induced acute haemolytic anaemia (haemolytic aneamia provoked by an immune mechanism, intra- and extra-erythrocyte defects, and HELLP syndrome were excluded). The anaemia progressed to become life-threatening for both the pregnant women and the foetus, which brought the following questions into consideration: diagnosis of anaemia during pregnancy; dosing of corticosteroid therapy; possibility of giving birth to a viable foetus and prognosis for next pregnancies. Owing to the inter-disciplinary efforts, the life and health of this pregnant woman were preserved, but the foetus was lost.

Prevalence & consequences of anaemia in pregnancy.

Science.gov (United States)

Kalaivani, K

2009-11-01

Prevalence of anaemia in India is among the highest in the world. Prevalence of anaemia is higher among pregnant women and preschool children. Even among higher income educated segments of population about 50 per cent of children, adolescent girls and pregnant women are anaemic. Inadequate dietary iron, folate intake due to low vegetable consumption, perhaps low B12 intake and poor bioavailability of dietary iron from the fibre, phytate rich Indian diets are the major factors responsible for high prevalence of anaemia. Increased requirement of iron during growth and pregnancy and chronic blood loss contribute to higher prevalence in specific groups. In India, anaemia is directly or indirectly responsible for 40 per cent of maternal deaths. There is 8 to 10-fold increase in MMR when the Hb falls below 5 g/dl. Early detection and effective management of anaemia in pregnancy can contribute substantially to reduction in maternal mortality. Maternal anaemia is associated with poor intrauterine growth and increased risk of preterm births and low birth weight rates. This in turn results in higher perinatal morbidity and mortality, and higher infant mortality rate. A doubling of low birth weight rate and 2 to 3 fold increase in the perinatal mortality rates is seen when the Hb is anaemia contributes to intergenerational cycle of poor growth in the offspring. Early detection and effective management of anaemia in pregnancy can lead to substantial reduction in undernutrition in childhood, adolescence and improvement in adult height.

We describe the case of a 17-month-old boy with a hypochromic microcytic anaemia, refractory to oral iron treatment. After exclusion of dietary and gastrointestinal causes of iron deficiency, a genetic cause for iron deficiency was confirmed by finding two mutations in the TMPRSS6 gene, consistent with a diagnosis of iron-refractory iron deficiency anaemia (IRIDA).

We have reported a case of aplastic crisis occurring in an 11-year-old black boy with occult hereditary spherocytosis. An etiologic diagnosis of human parvovirus (HPV) B19 infection was confirmed serologically. The Coulter Model S + IV proved useful for both diagnosis and treatment monitoring through serial histograms. The relationship of HPV infection and aplastic crisis is discussed.

Aplastic anemia is a hematologic condition occasionally presenting during pregnancy. This pathological process is associated with significant maternal and neonatal morbidity and mortality. Obstetric and anesthetic management is challenging, and treatment requires a coordinated effort by an interdisciplinary team, in order to provide safe care to these patients. In this review, we describe the current state of the literature as it applies to the complexity of aplastic anemia in pregnancy, focusing on pathophysiologic aspects of the disease in pregnancy, as well as relevant obstetric and anesthetic considerations necessary to treat this challenging problem. A multidisciplinary-team approach to the management of aplastic anemia in pregnancy is necessary to coordinate prenatal care, optimize maternofetal outcomes, and plan peripartum interventions. Conservative transfusion management is critical to prevent alloimmunization. Although a safe threshold-platelet count for neuraxial anesthesia has not been established, selection of anesthetic technique must be evaluated on a case-to-case basis. PMID:29535558

Cerebral microcirculation during experimental normovolaemic anaemia

Full Text Available Anaemia is accepted amongst critically ill patients as an alternative to elective blood transfusion. This practice has been extrapolated to head injury patients with only one study comparing the effects of mild anaemia on neurological outcome. There are no studies quantifying microcirculation during anaemia. Experimental studies suggest that anaemia leads to cerebral hypoxia and increased rates of infarction, but the lack of clinical equipoise when testing the cerebral effects of transfusion amongst critically injured patients, supports the need of experimental studies. The aim of this study was to quantify cerebral microcirculation and the potential presence of axonal damage in an experimental model exposed to normovolaemic anaemia, with the intention of describing possible limitations within management practices in critically ill patients. Under non-recovered anaesthesia, six Merino sheep were instrumented using an intracardiac transeptal catheter to inject coded microspheres into the left atrium to ensure systemic and non-chaotic distribution. Cytometric analyses quantified cerebral microcirculation at specific regions of the brain. Amyloid precursor protein staining was used as an indicator of axonal damage. Animals were exposed to normovolaemic anaemia by blood extractions from the indwelling arterial catheter with simultaneous fluid replacement through a venous central catheter. Simultaneous data recording from cerebral tissue oxygenation, intracranial pressure and cardiac output was monitored. A regression model was used to examine the effects of anaemia on microcirculation with a mixed model to control for repeated measures. Homogeneous and normal cerebral microcirculation with no evidence of axonal damage was present in all cerebral regions, with no temporal variability, concluding that acute normovolaemic anaemia does not result in short term effects on cerebral microcirculation in the ovine brain.

Flow cytometry is the gold standard methodology for screening of paroxysmal nocturnal hemoglobinuria. In the last few years, proaerolysin conjugated with fluorescein (FLAER) has become an important component of antibody panel used for the detection of paroxysmal nocturnal hemoglobinuria (PNH) clone. This study aimed to compare PNH clone detection by flow cytometry in the pre-FLAER era versus the FLAER era. This was a retrospective analysis of 4 years and included 1004 individuals screened for PNH clone, either presenting as hemolytic anemia or as aplastic anemia. In the pre-FLAER time period, the RBCs and neutrophils were screened with antibodies against CD55 and CD59. With the introduction of FLAER, neutrophils were screened with FLAER/CD24/CD15 and monocytes with FLAER/CD14/CD33 combination. A comparative analysis was done for detection of PNH clone in aplastic anemia patients versus non-aplastic anemia patients, as well as between pre-FLAER and FLAER era. Out of a total of 1004 individuals, 59 (5.8%) were detected to have PNH clone positivity. The frequency of PNH clone detected in aplastic anemia and non-aplastic anemia groups was 12.02 and 3.36%, respectively. The detection rate of PNH clone increased from 4.5% (32/711) in the pre-FLAER era to 9.2% (27/293) with the introduction of FLAER. However, this increase could be attributed to increased detection of PNH clone in the aplastic anemia group, which showed a significant increase from 8.3 to 18.2% after use of FLAER. In the non-aplastic group, PNH clone was detected with similar frequencies before and after use of FLAER (3.2 versus 3.8%, respectively). Mean PNH clone size was lower in the aplastic anemia group when compared with the non-aplastic group. RBCs always showed a lower clone size than neutrophils. PNH clone on neutrophils and monocytes was however similar. Inclusion of FLAER increases the sensitivity of the test which is especially useful in picking up small PNH clones in patients of aplastic anemia.

Aplastic anemia is a rare but life-threatening disorder characterized by cytopenia in at least two of the three blood lineages. A frequent feature of patients with aplastic anemia is that they have shorter telomeres than those of age-matched controls. Testosterone has been used for over half a century in the treatment of aplastic anemia. However, although remissions are frequent following hormone therapy, the molecular mechanism underlying the response to treatment has remained unknown. Here we explored the possibility that the recently described regulation of telomerase activity by sex hormones may be the mechanism responsible. To this end, we used a mouse model of aplastic anemia induced by short telomeres in the bone marrow compartment. We found that testosterone therapy results in telomerase up-regulation, improved blood counts, and a significant extension of life-span of these mice. Importantly, longitudinal follow-up studies revealed longer telomeres in peripheral blood in mice subjected to hormone treatment. Our results demonstrate that testosterone-mediated telomerase activation can attenuate or reverse aplastic anemia disease progression associated with the presence of short telomeres.

Anaemia during pregnancy continues to constitute significant challenge to maternal health in Nigeria and contributes substantially to the worsening maternal mortality ratio (MMR) in Nigeria despite a global reduction in MMR in response to effort to improve safe motherhood. The incidence of anaemia during pregnancy is still high (>40 %) in Nigeria, and attitudes and management practices are yet unclear as the peoples' understanding of the phenomenon remains unclear. This study explored the perceptions/attitudes on anaemia during pregnancy and practices to prevent and/or manage it in Anambra State. In-depth interview and focus group discussion data were collected from health workers and mothers who delivered within 6 months preceding the study and from mothers and husbands of women who delivered within 6 months preceding the study, respectively. The people expressed some knowledge of anaemia, being common in pregnancies. However, some expressed the view that anaemia being a typical sign of pregnancy cannot be prevented. Some mothers expressed desire for focused antenatal care services to control anaemia but lamented the attitude of the health workers, who make access to these interventions difficult. Control of anaemia in pregnancy should start with providing health education to pregnant women and their partners, who reinforce what the women are told during antenatal care, and with training health workers for friendlier attitudes to clients.

An association between severe aplastic anemia and other autoimmune diseases is rare and has been described in adults for eosinophilic fasciitis, thymomas, systemic lupus erythematosus, and thyroid disorders. Herein we report a patient with celiac disease who was not strictly following a gluten-free diet and presented with progressive pallor, fever, and weakness of 1 month's duration. On investigation, he had pancytopenia, which on subsequent evaluation revealed aplastic anemia. An association between aplastic anemia and celiac disease has rarely been reported. To the best of author's knowledge, only 1 pediatric case of celiac disease associated with aplastic anemia has been published. This is the second report to suggest such an association in children.

Aplastic anemia patients who received rabbit antithymocyte globulin exhibited response and survival rates inferior to those who received horse antithymocyte globulin in several studies. Therefore, we conducted a meta-analysis to compare rabbit and horse antithymocyte globulin as immunosuppressive therapy for aplastic anemia. We searched online databases for studies that compared antithymocyte globulin regimens as first-line treatment for aplastic anemia, including both randomized and non-randomized controlled trials. The early mortality rate at 3 months and overall response rate at 6 months were evaluated. Thirteen studies were included in the analysis. The risk ratio (RR) of early mortality for rabbit vs. horse antithymocyte globulin was 1.33 [95% confidence interval (CI) 0.69-2.57; P = 0.39], with significant heterogeneity. A sensitivity analysis suggested higher early mortality rate in patients who received rabbit antithymocyte globulin. The overall response rate was significantly higher in patients who received horse antithymocyte globulin (RR 1.27; 95% CI 1.05-1.54; P = 0.015). In conclusion, in aplastic anemia patients treated with ATG, early mortality rate was not significantly different in patients receiving horse or rabbit ATG, although a sensitivity analysis showed higher early mortality in the rabbit ATG group. Horse ATG was associated with significantly higher response rate than rabbit ATG.

Anaemia and thyrotoxicosis are both relatively common. It is unclear whether thyrotoxicosis results in anaemia in the absence of other causes. The aim of this study was to determine the prevalence and characteristics of anaemia in patients with thyrotoxicosis. A prospective cohort study of patients with thyrotoxicosis. 353 patients referred to a regional endocrinology centre in New Zealand from March 2013 to November 2014 for new-onset thyrotoxicosis. Detailed assessment including thyroid function tests, full blood count, inflammatory markers, haematological parameters and coeliac serology. Anaemia was defined as a haemoglobin value cause(s) for the anaemia. Only 10 patients (2.8% of the entire cohort) had anaemia not clearly attributable to another cause. Median free thyroid hormone levels were higher in those with anaemia of unknown cause compared to patients with thyrotoxicosis alone. The median duration of anaemia was shorter in patients with thyrotoxicosis-associated anaemia compared to those with anaemia due to an underlying cause (1 vs 6 months, P = .001). In all patients with thyrotoxicosis-associated anaemia, the anaemia resolved, either prior to, or on becoming euthyroid. Anaemia coexisting with thyrotoxicosis is less common than previously reported and is mild and transient. Patients with thyrotoxicosis and significant anaemia should be investigated for other potential causes, particularly when anaemia persists. © 2018 John Wiley & Sons Ltd.

For treatment of severe aplastic anemia, immunosuppressive therapy with horse antithymocyte globulin results in superior response and survival compared with rabbit antithymocyte globulin. This relative benefit may be different in the setting of transplantation as rabbit antithymocyte globulin results in more profound immunosuppression. We analyzed 833 severe aplastic anemia transplants between 2008 and 2013 using human leukocyte antigen (HLA)-matched siblings (n=546) or unrelated donors (n=287) who received antithymocyte globulin as part of their conditioning regimen and bone marrow graft. There were no differences in hematopoietic recovery by type of antithymocyte globulin.

In Essen 121 bone marrow transplantations were carried out. The indications were severe aplastic anemia, acute leukemia in relapse, acute leukemia in remission or chronic myeloid leukemia. The conditioning regimen consisted of cyclophosphamide or the combination of cyclophosphamide and total body irradiation. All patients were treated under strict gnotobiotic care. To mitigate the risk of CMV infections intravenous CMV-hyperimmunoglobulin and CMV-negative blood products have been applied routinely since two years. MTX was used as prophylaxis against GVH-disease. In case of severe aplastic anemia 13 patients (72%) are still alive with a median observation time of 24 months. In the prognostically unfavourable group of acute leukemia in relapse only one patient showed long term survival. In this patient leukemic relapse occurred six years after transplantation. The survival rate of AML patients grafted during the first remission is 55% with a median observation time of 40 months. For patients grafted in the first consecutive remission of ALL the survival rate is 42% with a maximal observation time of 29 months. Out of 37 patients grafted because of CML, eight were in an advanced stage of the disease. 13 patients are still alive, the maximal observation time is 37 months. The overall incidence of GVHD in patients at risk was 28% in aplastic anemia, 26% in AML, 9% in ALL and 63% in CML. In aplastic anemia no patient developed an interstitial pneumonia. In leukemia the risk of fatal interstitial pneumonia was 34%.

Full Text Available New challenges and priorities are given in the EU Health programme 2007-2013. The objectives of the programme are to improve citizens’ health security, to promote health to improve prosperity and solidarity, and to generate and disseminate health knowledge. If challenges and priorities have been defined globally for rare diseases by the European Commission, persons involved in rare anaemias have taken the opportunity to contribute to the empowerment of patients with rare anaemias. One of the ENERCA partners objectives was the mapping of existing centres that take care of patients with rare anaemias in Europe. Another goal was to obtain a directory of facilities available per centre for patients with rare anaemias. We thought that with those results it could realistically help to define a consensus regarding the criteria to be recognised as a centre of expertise for haemoglobinopathies and very rare anaemias.

Anaemia is a common clinical finding in HIV infected women and has been associated with advanced disease. The use of antiretroviral drugs such as Zidovudine (ZDV) either for prevention of mother to child transmission (MTCT) of HIV or used in combination with other antiretrovirals have been implicated in the development or increased severity of anaemia. We report the prevalence, type, severity and incidence of anaemia in a cohort of HIV infected women who initiated antiretroviral prophylaxis or treatment during pregnancy. This is a retrospective cohort data analysis of 408 HIV infected pregnant women who participated in a breastfeeding intervention study (HPTN 046 Study, ClinicalTrials.gov NCT 00074412) in South Africa. Women initiated zidovudine prophylaxis for PMTCT or triple antiretroviral treatment in pregnancy according to the standard of care.

Horse antithymocyte globulin (h-ATG) (ATGAM(®) ) is the first choice of treatment in very severe patients with aplastic anemia who do not have any HLA matched sibling donor. h-ATG is a heterologous serum that may cause anaphylaxis. Alternative treatment strategies must be planned in case of hypersensitivity. Desensitization must be considered in patients without an alternative treatment of choice. We aimed to present the h-ATG desensitization protocol and consider its effectiveness in patients with aplastic anemia who are hypersensitized with h-ATG and do not have an alternative treatment of choice. Skin prick tests were performed with non-diluted solution in eight very severe patients with aplastic anemia who are followed up in Ege University Children's Hospital. Although skin prick test was found negative in these eight patients, different dilution h-ATG intradermal tests were performed and found positive in all patients. h-ATG desensitization program was started to these hypersensitized patients. Desensitization program was started to six male and two female very severe patients with aplastic anemia whose ages were between seven and 19 yr (median: 12.9 yr). All of the patients completed the desensitization program. While local reaction was seen in two patients, systemic reaction was seen in one patient and late reaction was seen in one patient during and after desensitization program. A successful desensitization program with h-ATG in children with aplastic anemia is presented. Even though there is not an exposure before to such high allergy potential heterologous serum, skin tests should be performed and desensitization must be started to patients who are hypersensitized to h-ATG. As the expected effectiveness of the treatment is so much, the desensitization protocol can be carried out safely and effectively with trained stuff although allergic reactions can be seen. © 2015 John Wiley & Sons A/S.

Patients with acquired and inherited bone marrow failure syndromes (BMFS) have ineffective hematopoiesis due to impairments of the hematopoietic stem cell compartment. Common manifestations of BMFS include varying degrees of peripheral blood cytopenias and, sometimes, progression to acute myelogenous leukemia. Research efforts have been made all over the world to improve understanding of the pathogenesis of these diseases and their clinical implications. The Aplastic Anemia and MDS International Foundation (AAMDSIF) is an independent nonprofit organization whose mission is to help patients and family members cope with BMFS. Here, we summarize recent scientific discoveries in several BMFS that were presented at the fifth International Bone Marrow Failure Disease Scientific Symposium 2016 that AAMDSIF sponsored on March 17-18, 2016, in Rockville, Maryland.

Hematopoietic patterns have been assessed in chronic 60 Co gamma irradiated dogs during preclinical phases of evolving aplastic anemia (AA) or myeloproliferative disease (MPD), principally myeloid leukemia. The results support the concept that acquired radioresistance of vital granulocyte/monocyte lineage-committed hematopoietic progenitors is temporally, perhaps causally, linked to the processes mediating hematopoietic recovery and accommodation under chronic irradiation, and in turn to preclinical events of evolving MPD. In addition, the marked differential responses of progenitors to gamma and neutron irradiation in vitro might suggest differences in the nature of cellular lesions elicited by chronic gamma irradiation, in vivo.

We present a case of a 73-year-old woman with transfusion-dependent anaemia thought to be secondary to an unidentifiable inflammatory condition. Anaemia evaluation including multiple bone marrow biopsies was unrevealing, with the exception of a non-specific elevation of her erythrocyte sedimentation rate and C-reactive protein. She had no identifiable inflammatory condition and did not meet the criteria for myelodysplastic syndrome. She was empirically treated with lenalidomide and achieved a complete response, suggesting that this immunomodulatory drug could potentially have a role in treating a subgroup of patients with immune-mediated anaemia. 2016 BMJ Publishing Group Ltd.

In spite of intervention efforts, in Uganda, as in other developing countries, high levels of anaemia among pregnant women continue. Anaemia among women of reproductive age (15-49 years) is a matter of national concern. This study was carried out to assess determinants of anaemia in Kiboga district. This was a single cross-sectional, descriptive survey. The anaemia status of the pregnant women was determined by measuring their haemoglobin levels. Possible determinant factors including socio-economic characteristics, knowledge, attitudes, practices and food intake were assessed using a structured questionnaire. Results showed that the prevalence of anaemia among pregnant women in Kiboga district was high enough (63.1%) to be described as a severe public health problem. The uptake and utilisation of the public-health intervention package to combat anaemia in pregnancy was low, with iron/folic acid supplementation at 13.2%, use of intermittent preventive treatment of malaria 45.4%, and use of de-worming medicines 14.5%. Women from households without a functional radio were 2.07 times more likely be anaemic (95%CI, 1.08-3.00) compared with women from households where there was a functional radio. There was little awareness and functional knowledge about anaemia among pregnant women. The high prevalence of anaemia observed in Kiboga district can be attributed to poverty and limited access to nutrition and health education information which lead to low uptake and utilization of the public-health intervention package to combat anaemia in pregnancy.

This study was designed to compare the effects of the anti-human T lymphocyte globulin (Fresenius, ATG-F)and rabbit anti-human thymocyte immunoglobulin (Genzyme, R-ATG)in the treatment of childhood aplastic anemia (AA) and their effects. A total of 59 children with aplastic anemia were analyzed in the present study, including 34 cases of severe aplastic anemia (SAA), 12 cases of very severe aplastic anemia (VSAA) and 13 cases of transfusion-dependent non-severe aplastic anemia (NSAA). While receiving immunosuppressive therapy (IST), 30 and 29 patients, with long-term oral supplement with cyclosporin A (CSA), androgen and Chinese traditional medicines, were treated with ATG-F and R-ATG, respectively. When it was necessary, some supportive cares such as component transfusion and infection control were also employed. Absolute counts of peripheral blood lymphocyte (ALC) at various time points were dynamically detected after ATG therapy. According to the International Aplastic Anemia Treatment and Effect standards. There were no statistically significant differences in the overall response rate (67%(20/30)vs. 69%(20/29), χ(2)=0.036, P=0.676) and the survival rate (87%(26/30)vs. 83%(24/29), χ(2)=0.173, P=0.676) between the ATG-F and R-ATG groups. There were significant and long-term ALC decrease after ATG therapy, the rate of ALC decrease in ATG-F and R-ATG group, the ALC only recovered to 47.8% (ATG-F group) and 47.4% (R-ATG group) of the pre-treatment level respectively. ATG-F 5 mg/(kg·d) and R-ATG 3.75 mg/(kg·d)could achieve similar effects in the treatment of childhood AA, through similar significant clearance of T cells. Therefore, all of these suggest that ATG-F and R-ATG might serve as the drugs of front-line choice for IST in childhood AA patients who do not have an available human leukocyte antigen identical related donor.

[Insufficient evidence supporting iron supplementation in anaemia during pregnancy].

The Royal Dutch Organization of Midwives (KNOV) recently presented their practice guideline 'Anaemia in midwifery practice'. The guideline identified available evidence on diagnosis, prognosis and treatment of anaemia in pregnancy. Anaemia based on iron deficiency and subsequent treatment with iron supplementation are probably the most frequent aspects of care for pregnant women. However, there is surprisingly enough no evidence of the efficacy of iron supplementation treatment on relevant clinical outcomes in pregnant women with anaemia. We plead to make the next guideline a multidisciplinary one. Such a guideline may lead to a large pragmatic trial evaluating the efficacy of iron supplementation treatment for patients with anaemia.

Prepartum anaemia: prevention and treatment.

Milman, Nils

This review focuses on the occurrence, prevention and treatment of anaemia during pregnancy in Western societies. Iron deficiency anaemia (IDA) is the most prevalent deficiency disorder and the most frequent form of anaemia in pregnant women. Minor causes of anaemia are folate and vitamin B12 deficiency, haemoglobinopathy and haemolytic anaemia. Anaemia is defined as haemoglobin of pregnancy. The prevalence of prepartum anaemia in the third trimester ranges 14-52% in women taking placebo and 0-25% in women taking iron supplements, dependent on the doses of iron. In studies incorporating serum ferritin, the frequency of IDA in placebo-treated women ranges 12-17% and in iron-supplemented women 0-3%. Requirements for absorbed iron increase during pregnancy from 0.8 mg/day in the first trimester to 7.5 mg/day in the third trimester, on the average approximately 4.4 mg/day, and dietary measures are inadequate to reduce the frequency of prepartum IDA. However, IDA is efficiently prevented by oral iron supplements in doses of 30-40 mg ferrous iron taken between meals from early pregnancy to delivery. Treatment of IDA should aim at replenishing body iron deficits by oral and/or intravenous administration of iron. In women with slight to moderate IDA, i.e. haemoglobin of 90-105 g/L, treatment with oral ferrous iron of approximately 100 mg/day between meals is the therapeutic option in the first and second trimester; haemoglobin should be checked after 2 weeks and provided an increase of >or=10 g/L, oral iron therapy has proved effective and should continue. Treatment with intravenous iron is superior to oral iron with respect to the haematological response. Intravenous iron is considered safe in the second and third trimester, while there is little experience in the first trimester. Intravenous iron of 600-1,200 mg should be considered: (1) as second option if oral iron fails to increase haemoglobin within 2 weeks; (2) as first option at profound IDA, i.e. haemoglobin of

Full Text Available Anaemia is a common clinical finding in HIV infected women and has been associated with advanced disease. The use of antiretroviral drugs such as Zidovudine (ZDV either for prevention of mother to child transmission (MTCT of HIV or used in combination with other antiretrovirals have been implicated in the development or increased severity of anaemia. We report the prevalence, type, severity and incidence of anaemia in a cohort of HIV infected women who initiated antiretroviral prophylaxis or treatment during pregnancy.This is a retrospective cohort data analysis of 408 HIV infected pregnant women who participated in a breastfeeding intervention study (HPTN 046 Study, ClinicalTrials.gov NCT 00074412 in South Africa. Women initiated zidovudine prophylaxis for PMTCT or triple antiretroviral treatment in pregnancy according to the standard of care. Laboratory and clinical data in pregnancy, <72 hours and 2 weeks postdelivery were extracted from the main database and analysed.The mean Hb concentration was 10.6 g/dL at baseline and 262/408 (64.2% women were diagnosed with anaemia (Hb<11 g/dL in pregnancy, 48/146 (32.9% subsequently developed anaemia intrapartum or postpartum and 89/310 (28.7% of all cases of anaemia remained unresolved by 2 weeks postdelivery. In a univariate analysis, CD4 count and gravidity were significant risk factors for anaemia in pregnancy, RR 1.41; 1.23-1.61 (p<0.001 and 1.10; 1.01-1.18 (p = 0.02 respectively. After adjusting for antiretroviral regimen, age and gravidity in a multivariable analysis, only the CD4 count remains a significant risk factor for anaemia in pregnancy and postdelivery.In conclusion, anaemia was most common among women in the advanced stage of HIV infection (CD4<200 cells/mm3. There was no evidence of an association between ZDV or triple ARVs and anaemia.

Iron deficiency, the most common cause of anaemia in pregnancy worldwide, can be mild, moderate or severe. Severe anaemia can have very serious consequences for mothers and babies, but there is controversy about whether treating mild or moderate anaemia provides more benefit than harm. To assess the effects of different treatments for anaemia in pregnancy attributed to iron deficiency (defined as haemoglobin less than 11 g/dL or other equivalent parameters) on maternal and neonatal morbidity and mortality. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (7 June 2011), CENTRAL (2011, Issue 5), PubMed (1966 to June 2011), the International Clinical Trials Registry Platform (ICTRP) (2 May 2011), Health Technology Assessment Program (HTA) (2 May 2011) and LATINREC (Colombia) (2 May 2011). Randomised controlled trials comparing treatments for anaemia in pregnancy attributed to iron deficiency. We identified 23 trials, involving 3.198 women. We assessed their risk of bias. Three further studies identified are awaiting classification. Many of the trials were from low-income countries; they were generally small and frequently methodologically poor. They covered a very wide range of differing drugs, doses and routes of administration, making it difficult to pool data. Oral iron in pregnancy showed a reduction in the incidence of anaemia (risk ratio 0.38, 95% confidence interval 0.26 to 0.55, one trial, 125 women) and better haematological indices than placebo (two trials). It was not possible to assess the effects of treatment by severity of anaemia. A trend was found between dose and reported adverse effects. Most trials reported no clinically relevant outcomes nor adverse effects. Although the intramuscular and intravenous routes produced better haematological indices in women than the oral route, no clinical outcomes were assessed and there were insufficient data on adverse effects, for example, on venous thrombosis and severe allergic reactions

Current trends in renal anaemia management place greater emphasis, and thus increased workload, on the role of the nurse in haemodialysis settings. However, there is little evidence that demonstrates the relationship between nurse staffing and patient outcomes. To describe nurse staffing in haemodialysis settings, its relationship with target levels of renal anaemia management and to describe target level achievement for different ways of organising anaemia management. Cross-sectional audit. Forty (out of 78) haemodialysis centres in Sweden reported quality assurance data. The numbers of bedside registered nurses, licensed nurse assistants and patients undergoing haemodialysis during a predefined morning shift; type of anaemia management and achieved target levels of anaemia management. The mean patient:registered nurse ratio was 2.4 and the mean patient:nurse assistant ratio was 12.8. There were no significant relationships between registered nurse staffing and target level achievement. On average, 45.6% of the patients had haemoglobin within the target levels at centres applying nurse-driven anaemia management, compared with 47.3% at physician-driven centres. These cross-sectional data suggest that renal anaemia outcomes are unrelated to the patient:registered nurse ratio. There is, however, room for improvement in renal anaemia management in the units included in this study, particularly the achievement of target levels of haemoglobin and transferrin saturation. © 2016 European Dialysis and Transplant Nurses Association/European Renal Care Association.

High-dose cyclophosphamide has long been used an anticancer agent, a conditioning regimen for hematopoietic stem cell transplantation and as potent immunosuppressive agent in autoimmune diseases including aplastic anemia. High-dose cyclophosphamide is highly toxic to lymphocytes but spares hematopoietic stem cells because of their abundant levels of aldehyde dehydrogenase, the major mechanism of cyclophosphamide inactivation. High dose cyclophosphamide therapy induces durable remissions in most patients with acquired aplastic anemia. Moreover, high-dose cyclophosphamide without hematopoietic stem cell rescue has shown activity in a variety of other severe autoimmune diseases. Here we review the history of cyclophosphamide as is applies to aplastic anemia (AA) and other autoimmune diseases. Included here are the historical data from early patients treated for AA as well as an observational retrospective study in a single tertiary care hospital. This latter component was designed to assess the safety and efficacy of high-dose cyclophosphamide therapy without stem cell rescue in patients with refractory autoimmune diseases. We analyzed fully the 140 patients with severe, progressive autoimmune diseases treated. All patients discussed here received cyclophosphamide, 50 mg/kg per day for 4 consecutive days. Response, relapse and overall survival were measured. Response was defined as a decrease in disease activity in conjunction with a decrease or elimination of immune modulating drugs. Relapse was defined as worsening disease activity and/or a requirement of an increase in dose of, or administration of new, immunosuppressive medications. Hematologic recovery occurred in all patients. The overall response rate of the was 95%, and 44% of those patients remain progression-free with a median follow up time of 36 (range 1–120) months for the 140 patients analyzed together. The overall actuarial and event free survival across all diseases at 60 months is 90.7% and 20

2011-10-01

The incidence of aplastic anemia is reported to be higher in Asia than elsewhere. We studied the frequency of human leukocyte antigen (HLA) DRB1 alleles in aplastic anemia patients from 2 genetically similar aboriginal groups, the Kadazan and the Dusun, and compared them with genetically matched community and hospital controls. HLA-DRB1*15 was significantly higher in the patients compared with controls (p = 0.005), confirming similar findings in Japanese and Caucasian studies. Further testing indicated a significantly higher frequency of HLA-DRB1*1501 in patients compared with controls (p = 0.0004) but no significant difference in the frequency of HLA-DRB1*1502. The high frequency of HLA-DRB1*15 in the Kadazan and Dusun population combined with the wide variety of environmental factors associated with aplastic anemia could be the reason for the elevated incidence of aplastic anemia in the Kadazan and Dusun in Sabah.

Objectives: To determine the frequency of anaemia in married women in Jutial, and to find out the relationship of risk factors of anaemia with levels of anaemia. Study Design: Cross-sectional study. Place and Duration of Study: Household survey carried out in Jutial, Gilgit 1st February 2008 to 30th April 2009. Patients and Method: Interview administered questionnaire along with blood sample collection using sterilized disposable syringes was used in this study on a total of 382 randomly selected, willing, married, non-pregnant, non-lactating women with one or more children. Results were considered significant if r-value was more than 0.5 with p-value less than 0.05. Results: Clinical analysis of the blood samples showed that the average haemoglobin (Hb) level was 12.8 g/dl. According to WHO standards, no woman had severe anaemia with Hb level below 7 g/dl. Majority of the women (77.5%) had normal Hb >= 12 g/dl. The calculated anaemia frequency of 22.5% was found to be little lower than that of national anaemia frequency of around 29 to 33%. Conclusion: Frequency of anaemia 22.5% can be attributed to good education system in Northern Area and the awareness of people towards health concerns. Another reason can be the initiatives by different NGOs working in the area specially Aga Khan Foundation to eradicate anaemia by developing a vast network of health facilities. Further research on the native foods, their extract nutritional values / iron contents and any special foods at higher altitudes may be more than 1500 meters can open new horizon to our understanding of anaemia in the northern areas.

Full Text Available INTRODUCTION Anaemia is a serious and prominent problem in the developing countries. This study evaluates the prevalence of anaemia in pregnant women attending the outpatient clinic in a semi-urban hospital for a period of six months. MATERIALS AND METHODS Data from a sample of 500 pregnant women was collected and the patients were screened for anaemia on their booking visit in KFMS&R for a period of six months from March-August 2015. Haemoglobin was estimated by cyanmethaemoglobin method using Systronic photocolorimeter on their first antenatal visit. The degree of anaemia was categorised according to ICMR datamild (10-10.99 g/dL, moderate (7-9.99 g/dL, severe (<7 g/dL. RESULTS It was observed that the prevalence of anaemia was 51.8% in the population under study. The prevalence of mild anaemia was 18.53%, that of moderate anaemia was 63.70% and that of severe anaemia was 17.76%. It was also noticed that the prevalence of anaemia was higher in young pregnant women between 17-21 years of age (63.26%. CONCLUSION Anaemia continues to be a major health problem in India and prevention and early diagnosis will significantly reduce maternal and perinatal morbidity and mortality.

A preparative regimen, consisting of total lymphoid irradiation and cyclophosphamide, was utilized in 40 patients with severe aplastic anemia undergoing allogeneic marrow transplantation. This regimen was successful in decreasing rejection in these previously transfused patients, as only one patient rejected the marrow graft. Twenty-nine of the 40 transplanted patients are surviving from 1.5 to 59 mo, with a median follow-up of 24 mo. The actuarial survival rate for these heavily transfused patients with aplastic anemia is 72% at 2 yr. This preparative regimen is extremely effective in decreasing rejection following transplantation for severe aplastic anemia. Future efforts in this area must be aimed at the elimination of graft-versus-host disease and control of fatal infections

Anaemia in pregnancy is an important reproductive health problem associated with increased maternal and perinatal morbidity and mortality. This study was undertaken to determine the prevalence of anaemia in pregnancy at booking in Gombe, North-eastern Nigeria. A cross-sectional study of 461 women attending the antenatal clinic was carried out. Anaemia in pregnancy was defined as a packed cell volume (PCV) of prevalence of anaemia at booking of 51.8%. The majority of these patients, 67.4%, were mildly anaemic, 30.5% were moderately anaemic while only 2.1% had severe anaemia. Most, 316 (68.5%) of the women booked in the second trimester while only 3.0% booked in the first trimester. There was no relationship between parity and anaemia in pregnancy in this study The majority of the women, 293 (63.5%) were in the lower social class. Because the majority of the anaemic gravidae are in the low social class, provision of haematinics at little or no cost will go a long way towards reducing the high prevalence of anaemia in pregnancy. In the long run, educational and economic empowerment of the women is the key to reducing the overall prevalence of anaemia to the barest minimum.

Full Text Available BACKGROUND Anaemia is the commonest nutritional deficiency disorder in the world and in India prevalence in pregnancy is 50-80%. It is a risk factor for preterm delivery, low birth weight, stillbirth and foetal anaemia. The aim of the study is to find out correlation between maternal and cord haemoglobin and birth weight of newborn. MATERIALS AND METHODS Prospective observational study of 150 pregnant women delivering in KIMS from December 2014 to June 2016 for antenatal and newborn haemoglobin and newborn weight. RESULTS Of 150 mothers, 89.33% are anaemic (24% mild, 44% moderate and 21.3% severe. The incidence of low birth weight and low cord haemoglobin varied directly with severity of anaemia. Out of 150 babies, 119 (79.3% of babies had anaemia in our study. The mean haemoglobin among babies was 12.9 g/dL with a S.D. of 2.01. CONCLUSION A significant positive correlation with maternal haemoglobin and newborn weight and cord haemoglobin. RecommendationAntenatal prophylaxis with iron and folic acid to prevent anaemia and incidence of low birth weight and infantile anaemia.

Neonatal screening for sickle cell anaemia is not common practice in the Democratic Republic of Congo, and we determined the prevalence in children with unknown electrophoresis of haemoglobin and anaemia. A cross-sectional study was conducted in four hospitals in the country's capital Kinshasa. We screened 807 patients with anaemia (Hb history of hand foot syndrome, in children who had received more than three transfusions and in children up to 36 months of age at their first transfusion. The high prevalence of sickle cell anaemia in children in Sub-Saharan Africa underlines the need for neonatal screening or, if that is not possible, screening of all children with severe anaemia to identify patients with the disease and provide early management. ©2015 Foundation Acta Paediatrica.

To assess the following associations between the second and third trimesters of pregnancy: (i) the intensity of soil-transmitted helminth (STH) infection and haemoglobin/anaemia, (ii) the effect of mebendazole treatment on the occurrence of STH infection, and (iii) the effect of mebendazole treatment on haemoglobin/anaemia. Data originated from a trial of 1042 pregnant women recruited in their second trimester and followed to delivery. Baseline assessments included socio-demographic/health information from questionnaires, haemoglobin/anaemia from HemoCue ascertainment of fingerprick blood, and the presence and intensity of STH (Ascaris lumbricoides, hookworms and Trichuris trichiura) infections from Kato-Katz examination. All women were given iron supplements; half were randomly allocated to receive single dose 500 mg mebendazole, and half, placebo. Haemoglobin/anaemia and STH infection status were determined again in the third trimester of pregnancy. Complete information was available from 935 (89.7%) women. Mebendazole significantly reduced the prevalence and intensity of all three STH infections. Higher intensities of hookworm and Trichuris infections in the second trimester were associated with a higher risk of anaemia in the third trimester. Overall, women with moderate/heavy Trichuris infection were found to be at a higher risk of anaemia; the highest risk was observed among those with moderate/heavy hookworm co-infection (adjusted OR = 2.77; 95% CI: 1.26, 6.11). Mebendazole treatment did not reduce the risk of anaemia. Higher intensities of both Trichuris and hookworm infections are associated with anaemia in pregnancy. The importance of Trichuris infections during pregnancy requires renewed attention. © 2011 Blackwell Publishing Ltd.

Anaemia occurs in 25% of people attending hospital diabetes clinics, but this may not be representative of all people with diabetes. We aimed to determine the prevalence of anaemia in a prospective population-based sample stratified by estimated glomerular filtration rate (eGFR) using the 4-point Modification of Diet in Renal Disease (MDRD) formula. All 7331 patients on our district register were stratified by eGFR. Seven hundred and thirty were approached by letter on two occasions. Two hundred and thirty-four (32%) returned questionnaires and blood samples. Responders (R), non-responders (NR) and the whole cohort (C) were similar: mean +/- sd age R 61.7 +/- 12.7 years; NR 61.3 +/- 15.1 years; C 61.8 +/- 14.2 years; diabetes duration R 8.8 +/- 8.6 years; NR 8.2 +/- 7.9 years; C 7.5 +/- 7.8 years, Type 1 diabetes R 10.1%, NR 10.8%, C 9.4%. Anaemia was defined using World Health Organization criteria: haemoglobin 60 ml/min per 1.73 m(2). Anaemia was as a result of erythropoietin deficiency in 34%, abnormal haematinics in 40% and was unexplained in 26% of patients. Five per cent of the patients had anaemia below the treatment threshold of 11 g/dl. The prevalence of unrecognized anaemia in population-based cohorts is lower than that in hospital-based studies. Current clinical surveillance in the UK is failing to detect anaemia in stage 3-5 chronic kidney disease (eGFR 60 ml/min per 1.73 m(2).

Yin and Yang of mesenchymal stem cells and aplastic anemia

Broglie, Larisa; Margolis, David; Medin, Jeffrey A

2017-01-01

Acquired aplastic anemia (AA) is a bone marrow failure syndrome characterized by peripheral cytopenias and bone marrow hypoplasia. It is ultimately fatal without treatment, most commonly from infection or hemorrhage. Current treatments focus on suppressing immune-mediated destruction of bone marrow stem cells or replacing hematopoietic stem cells (HSCs) by transplantation. Our incomplete understanding of the pathogenesis of AA has limited development of targeted treatment options. Mesenchymal stem cells (MSCs) play a vital role in HSC proliferation; they also modulate immune responses and maintain an environment supportive of hematopoiesis. Some of the observed clinical manifestations of AA can be explained by mesenchymal dysfunction. MSC infusions have been shown to be safe and may offer new approaches for the treatment of this disorder. Indeed, infusions of MSCs may help suppress auto-reactive, T-cell mediated HSC destruction and help restore an environment that supports hematopoiesis. Small pilot studies using MSCs as monotherapy or as adjuncts to HSC transplantation have been attempted as treatments for AA. Here we review the current understanding of the pathogenesis of AA and the function of MSCs, and suggest that MSCs should be a target for further research and clinical trials in this disorder.

Iron deficiency anaemia in Sri Lanka

International Nuclear Information System (INIS)

Liyanage, K.D.C.E.

1992-01-01

The commonest cause of nutritional anaemia in the Sri Lankan population is iron deficiency. The diets of the population belonging to the lower socio-economic groups contain little food of animal origin. Thus, their diets are deficient in easily absorbable (haem) iron; and are also heavily cereal-based. Therefore interference in the absorption of dietary iron also occurs. Iron-deficiency anaemia is not restricted to the so-called ''vulnerable groups'' in Sri Lanka, however, their greater demands make the problem not only commoner but also more severe. Among pregnant and lactating women anaemia is often associated with folate deficiency. It must also be noted that the low availability of dietary iron is compounded in large population groups. Malaria, presently raging on an epidemic scale is also a major contributory factor to the incidence of anaemia. The purpose of this study was to examine the iron status of pre-school children and pregnant women; to establish normal levels of biochemical indices at different trimesters; to record the effect of iron supplementation during pregnancy; and to record the bioavailability of iron from weaning foods and common adult diets. 6 figs, 14 tabs

Full Text Available Use of current models of Automated Haematology Analysers help in calculating the haemoglobin contents of the mature Red cells, Reticulocytes and percentages of Microcytic and hypochromic Red cells. This has helped the clinician in reaching early diagnosis and management of Different haemopoietic disorders like Iron Deficiency Anaemia, Thalassaemia and anaemia of chronic diseases. AIM This study is conducted using an Automated Haematology Analyser to evaluate anaemia using the Red Cell and Reticulocyte parameters. Three types of anaemia were evaluated; iron deficiency anaemia, anaemia of long duration and anaemia associated with chronic disease and Iron deficiency. MATERIALS AND METHODS The blood samples were collected from 287 adult patients with anaemia differentiated depending upon their iron status, haemoglobinopathies and inflammatory activity. Iron deficiency anaemia (n=132, anaemia of long duration (ACD, (n=97 and anaemia associated with chronic disease with iron deficiency (ACD Combi, (n=58. Microcytic Red cells, hypochromic red cells percentage and levels of haemoglobin in reticulocytes and matured RBCs were calculated. The accuracy of the parameters was analysed using receiver operating characteristic analyser to differentiate between the types of anaemia. OBSERVATIONS AND RESULTS There was no difference in parameters between the iron deficiency group or anaemia associated with chronic disease and iron deficiency. The hypochromic red cells percentage was the best parameter in differentiating anaemia of chronic disease with or without absolute iron deficiency with a sensitivity of 72.7% and a specificity of 70.4%. CONCLUSIONS The parameters of red cells and reticulocytes were of reasonably good indicators in differentiating the absolute iron deficiency anaemia with chronic disease.

Background. Malaria remains a major killer of children in Sub-Saharan Africa, while anaemia is a public health problem with significant morbidity and mortality. Examining the factors associated with moderate to severe anaemia (MdSA) and malarial anaemia as well as the haematological characteristics is essential. Methodology. Children (1–14 years) at presentation at the Regional Hospital Annex-Buea were examined clinically and blood samples were collected for malaria parasite detection and full blood count evaluation. Results. Plasmodium falciparum, anaemia, and malarial anaemia occurred in 33.8%, 62.0%, and 23.6% of the 216 children, respectively. Anaemia prevalence was significantly higher in malaria parasite positive children and those with fever than their respective counterparts. MdSA and moderate to severe malarial anaemia (MdSMA) were detected in 38.0% and 15.3% of the participants, respectively. The prevalence of MdSA was significantly higher in children whose household head had no formal education, resided in the lowland, or was febrile, while MdSMA was significantly higher in febrile children only. Children with MdSMA had significantly lower mean white blood cell, lymphocyte, and platelet counts while the mean granulocyte count was significantly higher. Conclusion. Being febrile was the only predictor of both MdSA and MdSMA. More haematological insult occurred in children with MdSMA compared to MdSA. PMID:27895939

Full Text Available In this case, we have presented that a patient has fankoni aplastic anemia with pancakes kidney in scintigraphy and ultrasonography. The patient is 10 years old and a girl who fanconi aplastic anemia had been diagnosed since three years. In physical examination her general status is good. There was not left hand thumb and she had double the distal phalanx in his right hand thumb in her inspection. We observed 2/6 sistolic murmur in cardiovascular system examınation. Other systems were natural. Abdominal ultrasonography was observed that both the kidney were ectopic location and fused view in the left lower quadrant. Similarly in Tc-99m DTPA and DMSA renal scintigraphy, both kidneys were fused and in the left hemipelvis. The right kidney function were significantly lower by comparison with the left kidney functions. Radiological imaging is necessary in patients with Fanconi aplastic anemia without present clinical symptoms. The renal ultrasonography is important for determining pancakes. In addition, static and dynamic renal scintigraphy plays an important role in revealing the functional status of the kidneys

To determine early effects on outcome from traumatic brain injury (TBI) induced by controlled cortical impact (CCI) associated with anaemia in mice. Outcome from TBI with concomitant anaemia would be worse than TBI without anaemia. CCI was induced with electromagnetic impaction in four groups of C57BL/6J mice: sham, sham+anaemia; TBI; and TBI+anaemia. Anaemia was created by withdrawal of 30% of calculated intravascular blood volume and saline replacement of equal volume. Functional outcome was assessed by beam-walking test and open field test (after pre-injury training) on post-injury days 3 and 7. After functional assessment, brains removed from sacrificed animals were pathological reviewed with haematoxylin and eosin, cresyl violet, Luxol Fast Blue, and IBA-1 immunostains. Beam-walking was similar between animals with TBI and TBI+anaemia (p = 0.9). In open field test, animals with TBI+anaemia walked less distance than TBI alone or sham animals on days 3 (p < 0.001) and 7 (p < 0.05), indicating less exploratory and locomotion behaviours. No specific pathologic differences could be identified. Anaemia associated with TBI from CCI is associated with worse outcome as measured by less distance travelled in the open field test at three days than if anaemia is not present.

Late patronage of antenatal care by women in low-resource areas makes timely intervention at correcting anaemia difficult. This study aimed to identify modifiable sociodemographic factors that predict anaemia before commencing antenatal care and make appropriate recommendation. A survey of sociodemographic features and haemoglobin concentrations of 232 women booking for antenatal care was conducted. Anaemia was diagnosed in 119 (51.3%), of which 87 (37.5%) had mild anaemia and 32 (13.8%) were moderately anaemic. There was no severe anaemia. Anaemia was highest among respondents who were 35 years of age, Muslims, of Igbo ethnicity (64.3%), single (55.0%), student/unemployed (58.8%), nulliparous (57.3%) and those who registered at 21 weeks' gestation (54.2%). Only occupation of the woman showed association with anaemia before antenatal care (p 0.007). A personal source of income may reduce anaemia in pregnancy; and it is advisable to have a social welfare package for unemployed pregnant women.

Rational Management of Iron-Deficiency Anaemia in Inflammatory Bowel Disease

Vikner, Malene Elbaek; Weiss, Günter

2018-01-01

Anaemia is the most frequent, though often neglected, comorbidity of inflammatory bowel disease (IBD). Here we want to briefly present (1) the burden of anaemia in IBD, (2) its pathophysiology, which mostly arises from bleeding-associated iron deficiency, followed by (3) diagnostic evaluation of anaemia, (4) a balanced overview of the different modes of iron replacement therapy, (5) evidence for their therapeutic efficacy and subsequently, (6) an updated recommendation for the practical management of anaemia in IBD. Following the introduction of various intravenous iron preparations over the last decade, questions persist about when to use these preparations as opposed to traditional and other novel oral iron therapeutic agents. At present, oral iron therapy is generally preferred for patients with quiescent IBD and mild iron-deficiency anaemia. However, in patients with flaring IBD that hampers intestinal iron absorption and in those with inadequate responses to or side effects with oral preparations, intravenous iron supplementation is the therapy of choice, although information on the efficacy of intravenous iron in patients with active IBD and anaemia is scare. Importantly, anaemia in IBD is often multifactorial and a careful diagnostic workup is mandatory for optimized treatment. Nevertheless, limited information is available on optimal therapeutic start and end points for treatment of anaemia. Of note, neither oral nor intravenous therapies seem to exacerbate the clinical course of IBD. However, additional prospective studies are still warranted to determine the optimal therapy in complex conditions such as IBD. PMID:29342861

Macauley, Mavin; Nag, Satyajit

2011-04-19

Roth spots are white-centred retinal haemorrhages, previously thought to be pathognomonic for subacute bacterial endocarditis. A number of other conditions can be associated with Roth spots. In this case, the authors describe the association of Roth spots and pernicious anaemia. This association has been rarely described in the medical literature. Correct diagnosis and treatment with intramuscular vitamin B(12) injections resulted in complete resolution of the anaemia and Roth spots. The authors hope to alert clinicians to think of various differentials of Roth spots, and initiate prompt investigation and management.

THE IMMUNOLOGICAL CHARACTERISTIC OF RA PATIENTS WITH ANAEMIA

2014-07-01

Full Text Available Abstract. The aim of the investigation was to study the immunological characteristics of RA patients with anaemia. Clinical and laboratory data including the percentage of the main lymphocyte subclasses, phagocyte and DTH-effector activity, serum concentration of immunoglobulins, the percentage of cells producing IFNγ and/or IL-4 and percent of monocytes producing TNF. We revealed some significant clinical, laboratory and immunological differences between RA patients and healthy donors and between patients with and without anaemia. Our data demonstrate RA anemic patients to have more severe disorders than patients without anaemia. We also revealed some significant immunological differences between RA patients and healthy donors and between patients with and without anaemia, including percent of cells producing IFNγ and/or IL-4. Our data permit to conclude that RA patients have many different immunological disturbances, more severe in anaemic patients.

Anaemia management in cardio renal disease.

Silverberg, Donald S; Wexler, Dov; Iaina, Adrian; Schwartz, Doron

2010-05-01

Anaemia is common in congestive heart failure (CHF) and is associated with increased mortality, morbidity and progressive renal failure. The common causes of the anaemia are the associated renal failure and excessive cytokine production, both of which can cause depression of the erythropoietin (EPO) production in the kidney and depression of EPO response in bone marrow. The cytokines can also induce iron deficiency by increasing hepcidin production from the liver, which both reduces gastrointestinal iron absorption and reduces iron release from iron stores located in the macrophages and hepatocytes. Attempts to control this anaemia will have to consider the use of both erythropoiesis stimulating agents (ESA) as well as oral and, probably more importantly, intravenous (IV) iron. Studies of anaemia in CHF with ESA and oral or IV iron and even with IV iron alone have shown a positive effect on hospitalisation, fatigue and shortness of breath, cardiac and renal function, quality-of-life, exercise capacity and reduced beta natriuretic peptide and have not demonstrated an increase in cardiovascular damage related to therapy. Although some studies and meta-analyses have revealed improvement in these parameters others have not. Adequately powered long-term placebo-controlled studies of ESA and of IV iron in CHF are needed and are currently being carried out.

Objective: To study the clinical value of bone marrow immunoscintigraphy for evaluation of patients with aplastic anemia. Methods: Twelve patients with aplastic anemia underwent bone marrow immunoscintigraphy using 99 Tc m labelled anti-granulocyte monoclonal antibody BW250/183, 10 of them also underwent bone marrow imaging using 99 Tc m -sulfur colloid (SC) 2 - 3 days later. The semiquantitative indexes of bone marrow immunoscintigraphy of the patients were compared with those of control patients. Results: Bone marrow immunoscintigraphy was superior to 99 Tc m -SC bone marrow imaging. In patients with aplastic anemia, the accumulation of 99 Tc m -BW250/183 in bone marrow and spleen was lower and in liver and kidney was higher than those of control patients. Nine patients were found with multiple focal accumulation in bone marrow. Conclusion: Bone marrow immunoscintigraphy with 99 Tc m -BW250/183 plays an important role in evaluating patients with aplastic anemia

Anaemia during pregnancy is a common problem which affects both the mother's and her child's health. The aim of this study was to determine knowledge level on anaemia among pregnant women in Putrajaya. This study was also been carried out to identify the relationship between knowledge according to socio-demographic and antenatal characteristics. A total of 370 subjects were participated in this study. Subjects comprised of pregnant women who attended four health clinics in Putrajaya to undergo first antenatal visit for the current pregnancy. Socio-demographic information, antenatal characteristics and knowledge related to anaemia were collected using questionnaires. Blood samples were taken to identify hemoglobin level of subjects using Sysmex Hematology Analyzer machine (Sysmex Europe GmbH). The mean age of subjects was 30.2 ± 4.2 years and the mean hemoglobin level was 12.1 ± 4.8 g/dL. The median score for subject's knowledge towards anaemia was 84.2 corresponding to a high level of anaemia knowledge. Result of this study revealed that 55.7% of subjects had high knowledge on anaemia during pregnancy while 28.6% had moderate knowledge followed by 15.7% with low knowledge score. Most subjects correctly answered the general questions on the survey but under the assumption regarding the cause of anaemia. They were also lacking in knowledge regarding the risks of anaemia. Knowledge score was significantly associated with gestational week (peducation for pregnant women with regard to anaemia.

Since 1974, we have done bone marrow transplantation (BMT) in six patients of acute leukemia and two of aplastic anemia. Leukemia patients were premedicated by CY+TBI method; cyclophosphamide (CY) 60 mg/kg/day was administered for two successive days and two days later, total body irradiation (TBI) was done in a dose of 800 - 1000 rad at a rate of 20-28 rad/min by linear accerelator. Patients with aplastic anemia were premedicated by CY method; CY 50 mg/kg/day for four successive days. Bone marrow graft was obtained from donor under general anesthesia. The nucleated bone marrow cells, ranged from 0.7 x 10 10 to 1.4 x 10 10 were transfused into the patient intravenously. Any lethal side effects did not develop in all patient during these procedures. Two died on day 10 and 12 with septicemia. The other 6 patients showed engraftment of bone marrow indicated by rising blood counts, return of marrow cellularity and in one case by blood cytogenetic markers. Relapse of leukemia did not occur in five patients treated with CY + TBI method. Three patients with allogeneic BMT developed moderately severe to severe Graft versus Host Disease. Survival time after BMT were 12, 35, 63, 68, 98, 125 days. 15 months in leukemia, and 10 days, 12 + months in aplastic anemia. (author)

Severe Anaemia during Late Pregnancy

Full Text Available Vitamin B12 deficiency is uncommon in pregnancy, it occurs in 10–28% of uncomplicated pregnancies, and is associated with a few complications. We present a case report of a 21-year-old patient with severe anaemia during late pregnancy caused by vitamin B12 deficiency. At 38 weeks gestation and with a BMI of 48.9, a history of rupture of membranes was given but not confirmed. On examination, she appeared pale and therefore full blood counts were done. Interestingly her haemoglobin (Hb levels were 3.7 g/dL. Folate and vitamin B12 levels were also found to be low, and the diagnosis of anaemia caused by vitamin B12 deficiency was made. After treatment with vitamin B12 injections, folic acid and blood transfusions, the patient’s haemoglobin levels improved from 3.7 g/dL to 10.7 g/dL. The conclusion is that effective history taking, diagnosis, and management can prevent many complications that are usually associated with vitamin B12 deficiency anaemia.

Anaemia in pregnancy is a major public health problem especially in the low-income countries where it is highly prevalent. There has been no recent study in Uganda about the factors associated with anaemia in pregnancy. We aimed to assess the current haemoglobin (Hb) status and factors associated with anaemia (Hb anaemia were estimated using linear and logistic regression analysis. The mean Hb was 11.5 (± 1.38) g/dl and prevalence of anaemia (Hb anaemia in pregnancy were malaria infection (OR: 1.32, 95% CI: 1.11, 1.58), Human Immuno-deficiency Virus infection (OR: 2.13, 95% CI: 1.36, 2.90) and lack of iron supplementation (OR: 1.66, 95% CI: 1.36, 2.03). Intermittent presumptive treatment of malaria, maternal age and parity showed a weak association with anaemia in pregnancy The high prevalence of anaemia in pregnancy in our setting highlights the need to put more effort in the fight against malaria and HIV, and also ensure that pregnant women access iron supplements early in pregnancy.

2000-01-01

PURPOSE: Transient aplastic crisis is reported in an eight-month old child with sickle cell anemia and acute B19 parvovirus infection. This fact is uncommon in this age. PATIENT AND METHODS: The authors review the literature and describe a clinical case of an eight-month old child with sickle cell anemia presented with profound anemia and reticulocytopenia. His peripheral blood was analyzed for parvovirus B19 using the polymerase chain reaction (PCR), and for anti B19 immunoglobulin Ig M, and Ig G by enzyme-linked immunosorbent assay (ELISA). RESULTS: An eight-month old child with sickle cell anemia was admitted to the hospital with fever and profound anemia (HB = 3.8g/ dl) and reticulocytopenia (2%). A diagnosis of aplastic crisis was established. The results indicate that Ig M and PCR were positive and Ig G negative. The patient needed erytrocyte transfusion, and was discharged on hospital day 4. CONCLUSIONS: The clinical and laboratory features indicate that human parvovirus B19 was the etiologic agent of an aplastic crisis in an eight-month old child. According to the international literature this event is uncommon for this age; in addition, this is the first time it appears in the Brazilian literature.

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 H{sub 2}-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.

2016-10-01

To investigate the correlation of single nucleotide polymorphism (SNP) of Interleukin-2(IL-2)-330T/G with genetic susceptibility and the efficacy of immunosuppressive therapy in patients with aplastic anemia. The peripheral blood samples from 103 patients with aplastic anemia in our hospital were collected. Out of 103 patients 46 received immuosuppressive therapy and were observed for 4 months, and 100 healthy adults were selected as control. The electrophoresis and DNA sequence were performed. The polymerase chain reaction(PCR) was used to amplify the polymorphic gene segment of IL-2 -330T/G from 103 aplastic anemia patients and 100 healthy adults. The frequencis of IL-2-330 GG genotype and G allele were a little higher in patients with aplastic anemia than that in the healthy adults(12.6% vs 12.0%, P>0.05; 27.7% vs 33.5%, P>0.05), but not statistically significant(P>0.05); in the 103 patients with aplastic anemia, 46 received immunosuppressive therapy, whereas 29 patients showed response, no significant difference was found between the responders and non-responders in the IL-2-330 GG genotype and G allele (31.0% vs 48.3%, P>0.05; 64.8% vs 61.8%, P>0.05). IL-2 -330T/G gene polymorphism may not correlate with the susceptibility of aplastic anemia or the efficacy of immunosuppressive therapy.

Intraclutch variation in avian eggshell pigmentation: the anaemia hypothesis.

Science.gov (United States)

De Coster, Greet; De Neve, Liesbeth; Lens, Luc

2012-10-01

Many passerine species lay eggs that are speckled with dark protoporphyrin pigmentation. Because protoporphyrin is mainly derived from the blood, we here formulate and test a new hypothesis that links an increase in anaemia along the laying sequence to within-clutch variation in egg pigmentation. More intense pigmentation is expected if pigments accumulate during enhanced red blood cell production in response to anaemia. Reduced pigmentation is expected if pigments are derived from the degradation of red blood cells that circulate in smaller numbers due to blood loss. To test this hypothesis, we manipulated anaemia in great tit (Parus major) females by infesting the nests with hen fleas (Ceratophyllus gallinae) prior to egg laying. Polychromatophil (i.e., immature red blood cells) percentage, as a measure of blood cell production, was positively correlated with parasite load confirming that female great tits experienced stronger anaemia when infested with haematophagous parasites during egg laying. We found a positive relationship between spot darkness and laying order that weakened under high parasite load. This result suggests that anaemia in females due to blood-sucking parasites led to diminished protoporphyrin from disintegrated red blood cells and hence a decreased deposition of protoporphyrin. However, the overall increase in pigment darkness along the laying sequence suggests that pigments also accumulate by enhanced red blood cell production caused by anaemia due to egg production itself.

Full Text Available BACKGROUND Haemolytic anaemia is a well-recognised clinical problem. This study looks into the clinical profile of haemolytic anaemia and also attempts to find out the common underlying causative disease. It also tries to group the patients according to the clinical manifestations and underlying causes. MATERIALS AND METHODS This is a hospital-based observational study conducted in a tertiary care centre in Northern Kerala. Forty-four adult patients with clinical manifestations and laboratory evidence of haemolytic anaemia were identified and studied for a period of one year. RESULTS Maximum number of cases were seen in the age group of 20-40 years. The overall male-female ratio was 1.1:1. The most common presenting symptoms were features of anaemia like breathlessness, easy fatigability, headache and tiredness. Family history of anaemia was present in 34.1%. The most common signs observed were pallor and jaundice. The most common causes were autoimmune haemolytic anaemia and sickle cell anaemia. CONCLUSION Haemolytic anaemia mostly affects individuals in their 3rd and 4th decade. There is no significant difference in gender distribution of haemolytic anaemia. Haemolytic anaemia most commonly presents with symptoms of anaemia and jaundice. Commonest causes of haemolytic anaemia are autoimmune haemolytic anaemia and sickle cell anaemia.

Haploidentical donor (HID) hematopoietic stem cell transplantation (HSCT) is an alternative treatment method for severe aplastic anemia (SAA) patients lacking suitable identical donors and those who are refractory to immunosuppressive therapy (IST). The current study evaluated the feasibility of upfront haploidentical HSCT in SAA patients. We conducted a multicenter study based on a registry database. One hundred fifty-eight SAA patients who underwent upfront transplantation between June 2012 and September 2015 were enrolled. Eighty-nine patients had haploidentical donors (HIDs), and 69 had matched related donors (MRDs) for HSCT. The median times for myeloid engraftment in the HID and MRD cohorts were 12 (range, 9-20) and 11 (range, 8-19) days, with a cumulative incidence of 97.8 and 97.1% (P = 0.528), respectively. HID recipients had an increased cumulative incidence of grades II-IV acute graft-versus-host disease (aGVHD) (30.3 vs. 1.5%, P < 0.001), grades III-IV aGVHD (10.1 vs. 1.5%, P = 0.026), and chronic GVHD (cGVHD) (30.6 vs. 4.4%, P < 0.001) at 1 year but similar extensive cGVHD (3.4 vs. 0%, P = 0.426). The three-year estimated overall survival (OS) rates were 86.1 and 91.3% (P = 0.358), while the three-year estimated failure-free survival (FFS) rates were 85.0 and 89.8% (P = 0.413) in the HID and MRD cohorts, respectively. In multivariate analysis, survival outcome for the entire population was significantly adversely associated with increased transfusions and poor performance status pre-SCT. We did not observe differences in primary engraftment and survival outcomes by donor type. Haploidentical SCT as upfront therapy was an effective and safe option for SAA patients, with favorable outcomes in experienced centers.

2014-03-25

Iron deficiency is a common nutritional deficiency amongst women of childbearing age. Peri-partum iron deficiency anaemia (IDA) is associated with significant maternal, fetal and infant morbidity. Current options for treatment are limited: these include oral iron supplementation, which can be ineffective and poorly tolerated, and red blood cell transfusions, which carry an inherent risk and should be avoided. Ferric carboxymaltose is a new treatment option that may be better tolerated.The study was designed to assess the safety and efficacy of iron deficiency anaemia (IDA) correction with intravenous ferric carboxymaltose in pregnant women with mild, moderate and severe anaemia in the second and third trimester. Prospective observational study; 65 anaemic pregnant women received ferric carboxymaltose up to 15 mg/kg between 24 and 40 weeks of pregnancy (median 35 weeks gestational age, SD 3.6). Treatment effectiveness was assessed by repeat haemoglobin (Hb) measurements and patient report of well-being in the postpartum period. Safety was assessed by analysis of adverse drug reactions and fetal heart rate monitoring during the infusion. Intravenous ferric carboxymaltose infusion significantly increased Hb values (p anaemia in pregnancy.

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

International Nuclear Information System (INIS)

Whang, Kee Suk

1967-01-01

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- 59 Fe-disappearance rate, RBC 59 Fe net incorporation) did not significantly correlate with the degree of response to androgen in aplastic anemia.

Fanconi's anaemia is a severe refractory anaemia, associated with congenital malformations in approximately two-thirds of cases. Although these malformations may involve every organ system, suggestive dysmorphic features include growth retardation, radial ray deformities and urinary malformations. These malformations are not specific for Fanconi's anaemia, but should be recognized during pregnancy, or later in childhood, and suggest the possibility of inherited haematopoiesis disorders.

Full Text Available Severe anaemia is a major cause of morbidity and mortality in African children. The aetiology is multi-factorial, but interventions have often targeted only one or a few causal factors, with limited success.We assessed the contribution of different pathophysiological mechanisms (red cell production failure [RCPF], haemolysis and blood loss to severe anaemia in Malawian children in whom etiological factors have been described previously. More complex associations between etiological factors and the mechanisms were explored using structural equation modelling. In 235 children with severe anaemia (haemoglobin<3.2 mMol/L [5.0 g/dl] studied, RCPF, haemolysis and blood loss were found in 48.1%, 21.7% and 6.9%, respectively. The RCPF figure increased to 86% when a less stringent definition of RCPF was applied. RCPF was the most common mechanism in each of the major etiological subgroups (39.7-59.7%. Multiple aetiologies were common in children with severe anaemia. In the final model, nutritional and infectious factors, including malaria, were directly or indirectly associated with RCPF, but not with haemolysis.RCPF was the most common pathway leading to severe anaemia, from a variety of etiological factors, often found in combination. Unlike haemolysis or blood loss, RCPF is a defect that is likely to persist to a significant degree unless all of its contributing aetiologies are corrected. This provides a further explanation for the limited success of the single factor interventions that have commonly been applied to the prevention or treatment of severe anaemia. Our findings underline the need for a package of measures directed against all of the local aetiologies of this often fatal paediatric syndrome.

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.

To determine the prevalence of anaemia and factors associated with iron deficiency among school children in rural Kenitra, Morocco. 295 students between 6 and 16 years old composed the study group. The level of haemoglobin was measured in a group of 295 school children. The iron status was determined by ferritin level in serum, and anaemia was defined when haemoglobin educational status of the parents. The mean haemoglobin concentration was 12.4 g/dl in boys and 12.5 g/dl in girls, whereas the mean ferritin level was 26.7 microg/l in boys and 27.9 microg/l in girls. The overall prevalence of anaemia in the studied population was 12.2% and iron deficiency was 20.4%. There was a significant relationship between education of the mother and anaemia in children (p= 0.01). Serum ferritin (SF), serum iron concentrations and mean corpuscular volume (MCV) were significantly correlated with haemoglobin by multiple regression analysis. However, using logistic regression analysis, the results showed that anaemia was not significantly associated with gender, parents' employment and monthly family income. Anaemia remains a common problem in the young children particularly the primary education school boys of the households of low income. The results suggest also, that iron deficiency is an important determinant of anaemia in this population; however, whole anaemia cannot be solely explained by iron deficiency. Further studies are needed to consider micronutrients status and exposure to environmental pollutants.

2017-01-01

Hepatitis-associated aplastic anemia (HAA) is a rare variant of aplastic anemia in which patients present with severe pancytopenia after an episode of acute hepatitis. The marrow failure is often rapid, severe, and usually fatal if untreated. The preceding hepatitis is largely under-studied. Retrospective study of the clinical and histopathologic features of hepatitis in pediatric patients who subsequently developed aplastic anemia and comparison with consecutive cases of acute liver failure and random cases of autoimmune hepatitis during the same time frame. All 7 patients of HAA had significant elevations in aminotransferases and conjugated hyperbilirubinemia at initial presentation. Echoing liver function indices, cholestatic hepatitis with sinusoidal obstruction-type endothelial injury was seen histomorphologically. Autoimmune hepatitis serology such as anti-F-actin, anti-liver/kidney microsome, and hypergammaglobulinemia was negative in all patients. Five of 7 patients (71.4%) had, however, elevated antinuclear antibody, all with a speckled pattern. Hepatitis virus serology was negative in all patients. By immunohistochemical staining, the lobular CD8/CD4 lymphocyte ratio was markedly elevated in all of the initial samples with significant reduction in this ratio (P = 0.03) in 3 patients post treatment (ursodiol, antibiotics, and/or immunosuppressive therapy). Hepatitis preceding HAA is characterized by marked elevation of aminotransferases, conjugated hyperbilirubinemia, elevated antinuclear antibody with a speckled pattern, cholestatic hepatitis with sinusoidal obstruction morphology, and CD8 dominant lobular infiltrates. The present study suggests HAA may result from cytotoxic T-cell-mediated sinusoidal endothelial and hepatocytic injury.

Sickle cell anaemia is prevalent in sub Saharan Africa. While α+-thalassaemia is known to modulate sickle cell anaemia, its magnitude and significance in Uganda have hitherto not been described. To determine the prevalence of α+thalassaemia among sickle cell anaemia patients in Mulago Hospital and to describe the clinical and laboratory findings in these patients. A cross sectional study was carried out on patients with sickle cell anaemia in Kampala. Dried blood spots were used to analyze for the deletional α+ thalassaemia using multiplex polymerase chain reaction. Of the 142 patients with sickle cell anaemia, 110 (77.5%) had the αα+thalassaemia deletion. The gene frequency of (-α) was 0.425. Ninety one percent (100/110) of those with α+thalassaemia were heterozygous (αα/α-). Amongst the patients older than 60 months, 15 (83.3%) of those without αα+thalassaemia had significant hepatomegaly of greater than 4 cm compared to 36 (45.6%) of those with α+thalassaemia (p=0.003). The gene frequency of (-α) of 0.425 noted in this study is higher than that reported from many places in Africa. Concurrent alpha thalassemia might be a protective trait against significant hepatomegaly in sickle cell anaemia patients more than 60 months of age at Mulago hospital.

2009-11-01

The present study investigates the socioeconomic risk factors of anaemia among women belonging to eastern Indian states. An attempt has been made to find out differences in anaemia related to social class and place of residence, and age and marital status. It was hypothesized that rural women would have a higher prevalence of anaemia compared with their urban counterparts, particularly among the poorest social strata, and that ever-married women would be at elevated risk of anaemia compared with never-married women, particularly in the adolescent age group. Using data from National Family Health Survey-3, 2005-6, a nationally representative cross-sectional survey that provided information on anaemia level among 19,695 women of this region, the present study found that the prevalence of anaemia was high among all women cutting across social class, location and other attributes. In all 47.9% were mildly anaemic (10.0-11.9.9 g/dl), 16.1% were moderately anaemic (7.0-9.9 g/dl) and 1.6% were severely anaemic (nutritional status of women throughout the life-cycle.

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

1967-03-15

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-{sup 59}Fe-disappearance rate, RBC {sup 59}Fe net incorporation) did not significantly correlate with the degree of response to androgen in aplastic anemia.

Anaemia in pregnancy is a major public health and economic problem worldwide, that contributes to both maternal and fetal morbidity and mortality. The aim of the study was to calculate the prevalence of anaemia in early pregnancy in a cohort of 'low risk' women participating in a large international multicentre prospective study (n = 5 609), to identify the modifiable risk factors for anaemia in pregnancy in this cohort, and to compare the birth outcomes between pregnancies with and without anaemia in early gestation. The study is an analysis of data that were collected prospectively during the Screening for Pregnancy Endpoints study. Anaemia was defined according to the World Health Organization's definition of anaemia in pregnancy (haemoglobin prevalence of anaemia (2.2%), that having no marital partner was an independent risk factor for having anaemia (OR 1.34, 95% CI 1.01-1.78), and that there was no statistically significant effect of anaemia on adverse pregnancy outcomes (small for gestational age, pre-tem birth, mode of delivery, low birth weight, APGAR score pregnancy outcomes were however more common in those with anaemia than in those without. In this low risk healthy pregnant population we found a low anaemia rate. The absence of a marital partner was a non-modifiable factor, albeit one which may reflect a variety of confounding factors, that should be considered for addition to anaemia's conceptual framework of determinants. Although not statistically significant, clinically, a trend towards a higher risk of adverse pregnancy outcomes was observed in women that were anaemic in early pregnancy.

We report a case of Kell sensitized pregnancy with good neonatal outcome. Anti-K antibodies were detected in maternal serum in early pregnancy as a part of routine antibody screening test. The middle cerebral artery doppler monitoring and serial titers were carried out to screen for foetal anaemia. Despite of rising antibody titers, serial middle cerebral artery doppler was normal and did not showed foetal anaemia. The pregnancy was carried out till term and patient delivered at 37 weeks of pregnancy with no evidence of foetal anaemia. This case underlines the need of general screening on rare antibodies in all pregnant women and that non-invasive monitoring of foetal anaemia can be done with anti-k titers and middle cerebral artery Doppler.

Anaemia during pregnancy is associated with negative maternal and neonatal outcomes. However, there is limited data regarding prevalence and effects of anaemia during pregnancy in northern Tanzania. The objective of this study was to determine the prevalence and possible risk factors for anaemia and its effect on perinatal outcomes among pregnant women attending antenatal care in Moshi Municipality in northern Tanzania. A cohort of pregnant women aged 14-43 years and in their 3rd trimester, was recruited from two primary health care clinics between June 2002 and March 2004. Interviews, anthropometric measurements and haematological examinations were conducted on 2654 consenting women. Perinatal outcomes were recorded during delivery and at 1 week after delivery. Of the 2654 participants, 47.4% had anaemia (haemoglobin [Hb] anaemia (Hb= 9-10.9g/dl), 9.9% had moderate anaemia (Hb =7- 8.9g/dl), and 2.1% had severe anaemia (Hb Anaemia was significantly more prevalent in HIV-positive (56.4%) than in HIV-negative women (46.7%), (P = 0.01). In logistic regression anaemia was independently associated with maternal HIV (OR= 1.5), malaria (OR= 5.2), clinic of recruitment (OR= 1.5) and low income (OR= 1.9). Pregnant women with anaemia were more likely to have low birth weight (LBW) infants. Compared with non-anaemic women, the risk of LBW was 1.6 times and 4.8 times higher for children born to women with moderate and severe anaemia, respectively. In conclusion, anaemia in pregnancy is a severe public health problem in northern Tanzania. Control of maternal anaemia may be one important strategy to prevent LBW in this setting. Measures to prevent malaria and to control anaemia among all pregnant women irrespective of HIV status, should be strengthened. Outside of the health sector broader approaches for anaemia prevention targeting women of lower income, are required.

Anaemia is the most common complication of pregnancy and a predictor of poor maternal and foetal outcomes. HIV infection is now recognized as one of the major contributors to anaemia in pregnancy. It is therefore important to determine the burden and risk factors of anaemia in maternal HIV infection in others to plan effective prevention strategies as well as optimize management outcomes. To determine the prevalence and risk factors of anaemia in pregnant HIV positive Nigerians. The prevalence and possible risk factors of anaemia were investigated in HIV positive pregnant Nigerian women at a large HIV treatment clinic in southwestern Nigeria using a cross-sectional design between January 2006 and December 2011. Nine hundred and eighty-five (42.5 %) women of 2,318 HIV positive pregnant women seen during the period were anaemic by WHO standard defined by haemoglobin anaemia in HIV positive pregnant women after controlling for confounding variables. Anaemia was found to be high at 42.5 % among the HIV positive women studied and was found to be independently associated with short inter birth interval, presence of OIs, advanced HIV disease and use of zidovudine containing HAART regimen.

Epidemiological data of dietary patterns and anaemia among older Chinese remains extremely scarce. We examined the association between dietary patterns and anaemia in older Chinese, and to assess whether biomarkers of serum magnesium, C-reactive protein (CRP) and serum ferritin can mediate these associations. We analysed the 2009 China Health and Nutrition Survey data (2401 individuals aged ≥60 years for whom both dietary and biomarker data are available). Dietary data was obtained using 24 h-recall over three consecutive days. Fasting blood samples and anthropometry measurement were also collected. Factor analysis was used to identify dietary patterns. Factor scores representing dietary patterns were used in Poisson regression models to explore the association between each dietary pattern and anaemia. Of the 2401 participants, 18.9% had anaemia, 1.9% had anaemia related to inflammation (AI), and 1.3% had iron-deficiency anaemia (IDA). A traditional dietary pattern (high intake of rice, pork and vegetables) was positively associated with anaemia; a modern dietary pattern (high intake of fruit and fast food) was inversely associated with anaemia. Progressively lower magnesium and BMI levels were associated with increasing traditional dietary quartiles; while a progressively higher magnesium and BMI levels were associated with increasing modern dietary quartiles (p  0.05) in CRP and serum ferritin across quartiles for either dietary pattern. In the fully adjusted model, the prevalence ratio (PR) of anaemia, comparing the fourth quartile to the first quartile, was 1.75 (95% CI: 1.33; 2.29) for a traditional dietary pattern, and 0.89 (95% CI: 0.68; 1.16) for a modern dietary pattern. The association between dietary patterns and anaemia is mediated by serum magnesium. Traditional dietary pattern is associated with a higher prevalence of anaemia among older Chinese. Future studies need to examine whether correcting micronutrient deficiency (e.g. magnesium) by

Chatterjee, Ritam; Chattopadhyay, Sukalpa; Law, Sujata

2016-11-01

Aplastic anemia, the paradigm of bone marrow failure, is characterized by pancytopenic peripheral blood and hypoplastic bone marrow. Among various etiologies, inappropriate use of DNA alkylating drugs like cyclophosphamide and busulfan often causes the manifestation of the dreadful disease. Cell cycle impairment in marrow hematopoietic stem/progenitor compartment together with cellular apoptosis has been recognized as culpable factors behind aplastic pathophysiologies. However, the intricate molecular mechanisms remain unrevealed till date. In the present study, we have dealt with the mechanistic intervention of the disease by peripheral blood hemogram, bone marrow histopathology, cytopathology, hematopoietic kinetic study, scanning electron microscopy, DNA damage assessment and flowcytometric analysis of cellular proliferation and apoptosis in hematopoietic stem/progenitor cell (HSPC) rich marrow compartment using busulfan and cyclophosphamidemediated mouse model. To unveil the molecular mechanisms behind aplastic pathophysiology, we further investigated the role of some crucial mitotic and apoptotic regulators like Protein kinase-B (PKB), Gsk-3β, Cyclin-D1, PP2A, Cdc25c, Plk-1, Aurora kinase-A, Chk-1 regarding the hematopoietic catastrophe. Our observations revealed that the alteration of PKB-GSK-3β axis, Plk-1, and Aurora kinase-A expressions in HSPC compartment due to DNA damage response was associated with the proliferative impairment and apoptosis during aplastic anemia. The study established the correlation between the accumulation of DNA damage and alteration of the mentioned molecules in aplastic HSPCs that lead to the hematopoietic catastrophe. We anticipate that our findings will be beneficial for developing better therapeutic strategies for the dreadful disease concerned.

p53 downregulates the Fanconi anaemia DNA repair pathway.

Science.gov (United States)

Jaber, Sara; Toufektchan, Eléonore; Lejour, Vincent; Bardot, Boris; Toledo, Franck

2016-04-01

Germline mutations affecting telomere maintenance or DNA repair may, respectively, cause dyskeratosis congenita or Fanconi anaemia, two clinically related bone marrow failure syndromes. Mice expressing p53(Δ31), a mutant p53 lacking the C terminus, model dyskeratosis congenita. Accordingly, the increased p53 activity in p53(Δ31/Δ31) fibroblasts correlated with a decreased expression of 4 genes implicated in telomere syndromes. Here we show that these cells exhibit decreased mRNA levels for additional genes contributing to telomere metabolism, but also, surprisingly, for 12 genes mutated in Fanconi anaemia. Furthermore, p53(Δ31/Δ31) fibroblasts exhibit a reduced capacity to repair DNA interstrand crosslinks, a typical feature of Fanconi anaemia cells. Importantly, the p53-dependent downregulation of Fanc genes is largely conserved in human cells. Defective DNA repair is known to activate p53, but our results indicate that, conversely, an increased p53 activity may attenuate the Fanconi anaemia DNA repair pathway, defining a positive regulatory feedback loop.

Anaemia in pregnancy is a public health problem in developing countries. This study aimed to determine the prevalence, risk factors, and adverse perinatal outcomes of anaemia among pregnant women in Moshi Municipal, Northern Tanzania. This was a follow-up study conducted from October 2013 to June 2015. A total of 539 pregnant women were enrolled in this study. Interviews were conducted followed by determination of haemoglobin level. Women were followed up at delivery and at 7 days and 28 days after delivery. A total of 529 women were included in this analysis. Their mean age was 25.8 (SD 5.73). The prevalence of anaemia was 18.0% and 2% had severe anaemia. The clinic of recruitment and low education level of the women were the factors that were independently associated with anaemia during pregnancy. At delivery, there were 10 stillbirths, 16 low birth weight (LBW) newborns, and 2 preterm birth cases. No association was found between anaemia and LBW, preterm birth, or stillbirths. Anaemia in pregnancy was a mild public health problem in the study setting of Northern Tanzania.

To report the prevalence of anaemia by demographic characteristics and its secular trend over 13 years for south-east Chinese pregnant women, and to determine the focus of anaemia prevention in Chinese pregnant women. Prospective study of the data on Hb concentration and other demographic information from a large-scale population-based perinatal health surveillance system in south-east China. Fourteen cities or counties in Jiangsu and Zhejiang provinces. A total of 467 057 prenatal women who had participated in the perinatal health-care surveillance system and delivered babies from 1 January 1993 to 31 December 2005 and had a record of Hb in all three pregnancy trimesters. The overall prevalence of anaemia among pregnant women was 39.6 % from 1993 to 2005. Anaemia prevalence increased from the first (29.6 %) to the second (33.0 %) and third (56.2 %) trimesters. The prevalence of anaemia was higher in villagers, in women with less education and in women with higher gravidity or parity. The prevalence of anaemia in all of the trimesters was higher in the spring, summer and autumn and lower in the winter. The prevalence decreased from 1993 to 2005, from 53.3 % to 11.4 % for the first trimester, 45.6 % to 22.8 % for the second trimester and 64.6 % to 44.6 % for the third trimester. The prevalence of anaemia among pregnant women in Jiangsu and Zhejiang provinces decreased substantially from 1993 to 2005. However, anaemia in the third trimester is still a severe public health problem among pregnant women in these areas.

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

Full Text Available BACKGROUND In this tertiary care hospital, one of the common condition of all the patients attending the hospital is Anaemia, which is a decrease in haemoglobin content or decrease in haematocrit below the lower limit of the 95% reference range for the individual’s age and sex. The patient presents with varied symptoms of different grades, depending on the severity of anaemia, in different clinical settings. Common presenting symptoms of anaemia are generalised weakness, malaise, loss of appetite and muscular pains. METHODS All the patient samples received at the central laboratory for haemogram, complete blood counts and peripheral smear examination over the period of two years between June 2014 to May 2016 were included in the study. Anaemia cases were diagnosed depending on the criteria of the definition of anaemia, and morphological typing of anaemia was done based on the peripheral smear examination of all the cases with decreased haemoglobin level. Standard cell counter was used to estimate the Hb and other red cell indices, and corroborated with peripheral blood smear examination by standard Romanowsky stains. RESULTS A total of 810 cases of anaemia were diagnosed over the period of two years, of which morphological typing yielded 685 cases of Microcytic and hypochromic anaemia, 15 cases of Dimorphic anaemia, 22 cases of Macrocytic anaemia and 88 cases of Normocytic and normochromic anaemia. CONCLUSION Anaemia is one of the most common problems of patients attending this tertiary care hospital, and detection and morphological typing of anaemia is very helping in guiding the clinicians in diagnosis and further management of anaemias for better patient care.

Gallium 67 scanning is an effective method of detecting inflammatory lesions, especially abscesses. A 10-year-old boy with aplastic anemia and severe leukopenia and granulocytopenia had a psoas abscess diagnosed by gallium scan. The patient died with Candida sepsis 18 days after bone marrow transplantation. At autopsy, a chronic psoas abscess with Candida was found. The gallium scan offers a clinically effective and noninvasive means of evaluating suspected infection in the granulocytopenia patient. (U.S.)

Anaemia is common in haemodialysis patients and treating it with erythropoiesis-stimulating agents (ESAs) is complex due to many factors. To assess the usefulness of the Anaemia Control Model (ACM) in the treatment of anaemia in haemodialysis. ACM is a software that predicts the optimal dose of darbepoetin and iron sucrose to achieve target haemoglobin (Hb) and ferritin levels, and makes prescription suggestions. Study conducted in dialysis clinics lasting 18months with two intervention phases (IPs) with ACM (IP1, n:213; IP2, n:218) separated by a control phase (CP, n:219). The primary outcome was the percentage of Hb in range and the median dose of ESAs, and the secondary outcomes were transfusion, hospitalisation and cardiovascular events. Clinical and patient analyses were performed. Hb variability was assessed by the standard deviation (SD) of the Hb. We also analysed the patients with most of the suggestions confirmed (ACM compliant group). ACM increased the percentage of Hb in range: 80.9% in IP2, compared with 72.7% in the CP and reduced the intake of darbepoetin (IP1: 20 [70]; CP 30 [80] μg P=0.032) with less Hb fluctuation (0.91±0.49 in the CP to 0.82±0.37g/dl in IP2, P<0.05), improving in the ACM compliant group. The secondary outcomes decreased with the use of ACM. ACM helps to obtain better anaemia results in haemodialysis patients, minimising the risks of treatment with ESAs and reducing costs.

Iron deficiency anaemia is an important health problem in Morocco. This study was conducted to estimate the prevalence of anaemia among school children in Kenitra. The sample represents school children of all educational levels and age ranged between 6-15 years. The level of hemoglobin, haematocrit, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration was measured in a group of 271 school children. The seric iron was assessed and anaemia was defined when hemoglobin education of the mother and anaemia in children (p = 0.004) but not with the family income. It is concluded that improving the economic status of the family, women education and health education about balanced animal and plant food consumption are recommended strategies to reduce the burden of anaemia.

To investigate the prevalence, predictors, and management of anaemia in pregnancy. A multi centre study across 11 maternity units in the UK. Data were collected over a two week study period in 2008 on maternal history, haemoglobin (Hb) and ferritin concentrations, iron therapy during pregnancy and in the postpartum period. Logistic regression models were used to explore factors associated with anaemia during pregnancy. Main outcomes included anaemia, defined as Hbanaemia by 32 weeks gestation included young maternal age (odds ratio 1.96, 95% CI 1.38-2.79), non-white ethnic origin (odds ratios varied 1.37-2.89 depending on ethnic origin) and increasing parity (odds ratio 1.24, 95% CI 1.08-1.41). Of women who had postnatal Hb levels checked, 30% (309/1031) were anaemic and, depending on centre, 16% to 86% of these received iron therapy. Anaemia was reported in nearly one in four women in the antenatal period, and nearly one in three of the women who had a postpartum Hb checked. Despite national guidelines, there was considerable variation in administration of iron including low utilisation of parenteral iron therapy. Future research needs to focus on the consequences of iron deficiency anaemia for maternal and infant health outcomes and effectiveness of implementation strategies to reduce anaemia.

The aim of the study was to determine the prevalence of anaemia in pregnancy at booking and to determine factors associated with its occurrence in order to proffer solutions. This was a 12-month cross-sectional study of pregnant women attending the antenatal clinic for the first time (booking visit) at ESUTTH, Enugu, Nigeria from 1 April 2009 to 31 March 2010. Sociodemographic characteristics of the mothers were extracted using an already prepared proforma. The blood haemoglobin concentration and HIV status of the women were determined and the results were analysed. The prevalence rate of anaemia in pregnancy was 64.1%. Based on severity, 94.6%, 4.3%, 1.1% of them had mild, moderate and severe anaemia. The mean age of the anaemic women was significantly lower than that of the non-anaemic women (p = 0.0001). Those that had no formal education and those that booked for antenatal care in the 3rd trimester had a significantly higher prevalence of anaemia. HIV-positive pregnant women had a significantly higher prevalence of anaemia than HIV-negative pregnant women (p = 0.0072, odds ratio 2.37). It was concluded that the prevalence of anaemia in pregnancy from the study is unacceptably high. To achieve Millennium Development Goals 4 and 5, efforts must be geared towards its prevention to ensure a healthy baby and mother.

2009-01-01

Objective: To explore the clinical significance changes of serum TNF-α, VEGF and TSGF levels after treatment in patients with aplastic Anemia. Methods: Serum TNF-α(with RIA), VEGF(with ELISA) and TSGF(with biochemistry) levels were determined in 33 patients with aplastic anemia both before and after treatment and 35 controls. Results: Before treatment, the serum TNF-α, TSGF levels were significantly higher in the patients than those in controls (P<0.01), but serum VEGF levels were significantly lower in the patients (P<0.01). Serum TNF-α, TSGF levels were negatively correlated with levels of VEGF(r=-0.5192, -0.6018, P<0.01). After a course of treatment, the serum TNF-α, VEGF and TSGF levels, though corrected markedly, remained significantly different from those in controls (P<0.05). Conclusion: Determination of serum TNF-α, VEGF and TSGF levels after treatment might be of prognostic importance in patients with aplastic anemia. (authors)

Sherjil, A.; Saeed, Z.U.; Shehzad, S.; Amjad, R.

2010-01-01

Background: Iron deficiency anaemia and febrile seizures are two common diseases in children worldwide as well as in our country. Iron insufficiency is known to cause neurological symptoms like behavioural changes, poor attention span and learning deficits in children. Therefore, it may also be associated with other neurological disturbances like febrile seizures in children. Objective of our case-control study was to find association between iron deficiency anaemia and febrile seizures in children. Methods: This multicentre study was conducted in Department of Paediatrics HIT Hospital Taxila Cantt, Department of Paediatrics CMH Mangla and Department of Paediatrics POF Hospital Wah Cantt, from June 2008 to June 2010. Three hundred and ten children aged between 6 months to 6 years were included in the study. One hundred and fifty-seven children who presented with febrile seizures were our cases, while, 153 children who presented with febrile illnesses without seizures were recruited as controls. All patients were assessed for iron deficiency anaemia by measuring haemoglobin level, serum ferritin level, Mean Corpuscular Haemoglobin Concentration (MCHC) and Mean Corpuscular Volume (MCV). Patients with iron deficiency anaemia amongst controls and cases were documented. Percentages and Odds ratio were derived from the collected data. Results: 31.85% of cases (50 out of 157) had iron deficiency anaemia whereas, 19.6% of controls (30 out of 153) were found to have iron deficiency anaemia as revealed by low levels of haemoglobin level, serum ferritin level, Mean Corpuscular Haemoglobin Concentration and Mean Corpuscular Volume. Odds ratio was 1.93. Conclusion: Patients with febrile seizures are 1.93 times more likely to have iron deficiency anaemia compared to febrile patients without seizures. (author)

2000-05-01

Fanconi's anaemia is a severe refractory anaemia, associated with congenital malformations in approximately two-thirds of cases. Although these malformations may involve every organ system, suggestive dysmorphic features include growth retardation, radial ray deformities and urinary malformations. These malformations are not specific for Fanconi's anaemia, but should be recognized during pregnancy, or later in childhood, and suggest the possibility of inherited haematopoiesis disorders.

Anaemia and pregnancy: Anaesthetic implications

Directory of Open Access Journals (Sweden)

Anju Grewal

2010-01-01

Full Text Available Anaemia in pregnancy defined as haemoglobin (Hb level of < 10 gm/dL, is a qualitative or quantitative deficiency of Hb or red blood cells in circulation resulting in reduced oxygen (O 2 -carrying capacity of the blood. Compensatory mechanisms in the form of increase in cardiac output (CO, PaO 2 , 2,3 diphosphoglycerate levels, rightward shift in the oxygen dissociation curve (ODC, decrease in blood viscosity and release of renal erythropoietin, get activated to variable degrees to maintain tissue oxygenation and offset the decreases in arterial O 2 content. Parturients with concomitant medical diseases or those with acute ongoing blood losses may get decompensated, leading to serious consequences like right heart failure, angina or tissue hypoxemia in severe anaemia. Preoperative evaluation is aimed at assessing the severity and cause of anaemia. The concept of an acceptable Hb level varies with the underlying medical condition, extent of physiological compensation, the threat of bleeding and ongoing blood losses. The main anaesthetic considerations are to minimize factors interfering with O 2 delivery, prevent any increase in oxygen consumption and to optimize the partial pressure of O 2 in the arterial blood. Both general anaesthesia and regional anaesthesia can be employed judiciously. Monitoring should focus mainly on the adequacy of perfusion and oxygenation of vital organs. Hypoxia, hyperventilation, hypothermia, acidosis and other conditions that shift the ODC to left should be avoided. Any decrease in CO should be averted and aggressively treated.

The objective of the present study was to investigate the association between food patterns and anaemia among Chinese adults. It was a cross-sectional household survey undertaken in 2002. The sample contained 2849 men and women aged 20 years and above, and had a response rate of 89.0 %. Factor analysis was used to identify food patterns based on a food-frequency questionnaire. Logistic regression was used to relate food patterns to anaemia. A four-factor solution explained 30.5 % of the total variance. After adjusting for socio-demographic factors and four distinct food patterns, the 'traditional' (rice, vegetable, wheat flour), 'sweet tooth' (drinks, cake) and 'healthy' (whole grains, fruits, vegetables) patterns were independently associated with anaemia. 'Traditional' and 'sweet tooth' patterns were positively associated with anaemia, whereas the association with 'healthy' food pattern was negative. No association was observed between the 'macho' pattern (meat and alcohol) and anaemia. Compared with the lowest quartile (Q1) of the 'traditional' pattern, the highest quartile (Q4) had a higher risk of anaemia (men: odds ratio (OR) 2.60, 95 % CI 1.38, 4.88; women: OR 3.40, 95 % CI 2.14, 5.39). For the 'sweet tooth' pattern, compared with the lowest quartile (Q1), the OR of the highest quartile was 2.34 (95 % CI 1.47, 3.73) for men and 2.02 (95 %CI 1.31, 3.13) for women. The fourth quartile of healthy food was associated with a lower risk of anaemia (men: OR 0.50, 95 % CI 0.31, 0.79; women: OR 0.51, 95 % CI 0.34, 0.75). Women in the north had a higher risk of anaemia (OR 2.49, 95 %CI 1.80, 3.43). Food patterns were associated with anaemia in this area with a high prevalence of anaemia.

Maternal anaemia is a common problem in pregnancy, particularly in developing countries. The study was aimed at determining the factors associated with anaemia among a group of pregnant mothers who attended an antenatal clinic in Dhaka city. This cross-sectional study included 224 pregnant women, who visited the antenatal clinic of the Marie Stops, Dhaka. Demographic data and information on maternal age, gestational age, educational and income level, and socioeconomic status were collected from all the subjects. Haemoglobin status was measured to assess their anaemia. A qualified technician drew venous blood samples from them. The reference values of haemoglobin were categorized according to the World Health Organization (WHO) criteria as follows: normal (11 g/dL or higher), mild (10-10.9 g/dL), and moderate (7-9.9 g/dL). Mild and moderate levels of haemoglobin were defined as anaemic (haemoglobin levels of anaemia was significantly associated with age (p = 0.036), education (p = 0.002), income (p = 0.001), living area (p = 0.031). Results of binary logistic regression analysis showed that maternal anaemia was also significantly associated with age (p = 0.006), educational status (primary to 8th grade, p = 0.004; secondary and above, p = 0.002), living area (0.022), and income (0.021). A significant proportion of pregnant women were found anaemic. Most data showed education has animpact on awareness to use of health services and iron supplementation should be encouraged to improve the haemoglobin levels in pregnancy. The results indicate that anaemia is alarmingly high among pregnant women in Dhaka city. Maternal anaemia is associated with age, education level, income level, and living area. The results suggest that pregnant women and members of their families should be urgently educated to understand the importance of antenatal care.

(Very) severe acquired aplastic anemia ((v)SAA) and myelodysplastic syndrome (MDS) are rare diseases in childhood. (V)SAA is a bone marrow (BM) failure syndrome characterized by immune-mediated destruction of hematopoietic progenitors. MDS is a malignant clonal stem cell disorder, of which...... the hypoplastic variant is, in case of absence of a cytogenetic clone, difficult to separate from (v)SAA. Recently, studies provided a molecular signature of autoimmunity in adult (v)SAA, by showing oligoclonality based on the length of the TCR Vbeta CDR3 region. We investigated retrospectively the frequency...... and the discriminative value of TCR Vbeta CDR3 oligoclonality in pediatric (v)SAA and MDS patients. Peripheral blood (PB) and/or BM mononuclear cell samples of pediatric patients with (v)SAA (n=38), refractory cytopenia (MDS-RC) (n=28) and 18 controls were analysed via TCR Vbeta heteroduplex PCR analysis of extracted...

Anaemia in pregnancy is an important cause of maternal and neonatal mortality. It is a recognized co-morbidity of HIV infection. This study aimed to determine the risk of anaemia in HIV positive pregnant women. This is a cross sectional study of healthy pregnant women attending Adeoyo Hospital, a secondary health centre in South-western Nigeria over a 1-month period (January 2007). During the study period, 2737 eligible women presented for antenatal care. About 98% (2682) of these women consented to HIV testing. Over all, their mean (+ S.D) packed cell volume was 30.96% (+/- 4.13). The prevalence of HIV infection was 2.9% (95% CI 2.3% - 3.6%) and the overall prevalence of anaemia was 33.1%. Frequency of anaemia was significantly higher in HIV +ve women (57.3% vs. 42.7%, p = 0.00. OR = 2.81., CI = 1.72-4.58). HIV +ve women presented more frequently with moderate or severe anaemia. In the logistic regression analysis only HIV infection (OR = 2.4, 95% CI = 1.37-4.21) and primigravidity (OR = 1.25, 95% CI = 1.04-15.2) remained independently associated with anemia. Anaemia is common in HIV positive pregnant women in this environment. Care providers must endeavor to determine the HIV status of every pregnant woman especially if she presents with anaemia with a view to providing appropriate interventions.

Objective: To investigate the role of relevant cytokines in the development and pathogenesis of aplastic anemia. Methods: Plasma GM-CSF, IL-2, TPO (with RIA) and EPO (with CLIA) contents were measured in 100 patients (acute 43, chronic 57) with aplastic anemia and 50 controls. Complete blood count was also performed in all these subjects. Results: The peripheral RBC, WBC, platelet counts and GM-CSF contents were significantly lower in the patients with aplastic anemia than those in the controls (P<0.05), while the IL-2, EPO and TPO contents were significantly higher in the patients (P<0.05). GM-CSF contents were positively correlated with the WBC numbers. EPO contents were negatively correlated with the RBC counts and TPO contents were correlated (negatively) with the platelet counts. Conclusion: There was correlationship between each blood elements (WBC, RBC, platelet) and its corresponding cytokine (GS-CSF, EPO, TPO respectively). IL-2 contents were not correlated with WBC counts. (authors)

We receive fast track referrals on the basis of iron deficiency anaemia (IDA) for patients with normocytic anaemia or for patients with no iron studies. This study examined the yield of colorectal cancer (CRC) among fast track patients to ascertain whether awaiting confirmation of IDA is necessary prior to performing bowel investigations. A review was undertaken of 321 and 930 consecutive fast track referrals from Centre A and Centre B respectively. Contingency tables were analysed using Fisher's exact test. Logistic regression analyses were performed to investigate significant predictors of CRC. Overall, 229 patients were included from Centre A and 689 from Centre B. The odds ratio for microcytic anaemia versus normocytic anaemia in the outcome of CRC was 1.3 (95% confidence interval [CI]: 0.5-3.9) for Centre A and 1.6 (95% CI: 0.8-3.3) for Centre B. In a logistic regression analysis (Centre B only), no significant difference in CRC rates was seen between microcytic and normocytic anaemia (adjusted odds ratio: 1.9, 95% CI: 0.9-3.9). There was no statistically significant difference in the yield of CRC between microcytic and normocytic anaemia (p=0.515, Fisher's exact test) in patients with anaemia only and no colorectal symptoms. Finally, CRC cases were seen in both microcytic and normocytic groups with or without low ferritin. There is no significant difference in the yield of CRC between fast track patients with microcytic and normocytic anaemia. This study provides insufficient evidence to support awaiting confirmation of IDA in fast track patients with normocytic anaemia prior to requesting bowel investigations.

Full Text Available Abstract Background Anaemia during pregnancy is major health problem. There is conflicting literature regarding the association between anaemia and its severity and maternal and perinatal outcomes. Methods This is a retrospective case-control study conducted at Kassala hospital, eastern Sudan. Medical files of pregnant women with severe anaemia (haemoglobin (Hb 11 g/dl, n = 303. Logistic regression analysis was performed separately for each of the outcome measures: preeclampsia, eclampsia, preterm birth, low birth weight (LBW and stillbirth. Results There were 9578 deliveries at Kassala hospital, 4012 (41.8% women had anaemia and 303 (3.2% had severe anaemia. The corrected risk for preeclampsia increased only in severe anaemia (OR = 3.6, 95% CI: 1.4-9.1, P = 0.007. Compared with women with no anaemia, the risk of LBW was 2.5 times higher in women with mild/moderate anaemia (95% CI: 1.1-5.7, and 8.0 times higher in women with severe anaemia (95% CI: 3.8-16.0. The risk of preterm delivery increased significantly with the severity of anaemia (OR = 3.2 for women with mild/moderate anaemia and OR = 6.6 for women with severe anaemia, compared with women with no anaemia. The corrected risk for stillbirth increased only in severe anaemia (OR = 4.3, 95% CI: 1.9-9.1, P Conclusions The greater the severity of the anaemia during pregnancy, the greater the risk of preeclampsia, preterm delivery, LBW and stillbirth. Preventive measures should be undertaken to decrease the prevalence of anaemia in pregnancy.

We reviewed the records of antenatal clinic attendees over a period of 9 years to determine the prevalence of anaemia at booking. The laboratory records of 8751 out of a total of 37,506 pregnant women who booked for antenatal care between 2004 and 2013 at the BMSH were reviewed. The effects of maternal age, educational status, parity, gestational age, haemoglobin genotype and infections on the prevalence of anaemia were investigated. The prevalence of anaemia at booking was 69.6%, most of whom had moderate anaemia. Anaemia was significantly prevalent in the 10-19 year age group, and in women with secondary education, in their 2nd trimester and with SS genotype. Anaemia also increased with gestational age, this however was not statistically significant. There was no statistical difference between those who are human immunodeficiency virus (HIV) positive and had anaemia and those who are HIV negative who also had anaemia. This study shows that anaemia in pregnant women is still unacceptably high considering the consequences and despite interventions on the ground to reduce prevalence. There is a need to review the intervention measures with emphasis on programmes that would increase awareness among pregnant women and the general public.

The function of Fanconi anaemia proteins is to maintain genomic stability. Their main role is in the repair of DNA interstrand crosslinks, which, by covalently binding the Watson and the Crick strands of DNA, impede replication and transcription. Inappropriate repair of interstrand crosslinks causes genomic instability, leading to cancer; conversely, the toxicity of crosslinking agents makes them a powerful chemotherapeutic. Fanconi anaemia proteins can promote stem-cell function, prevent tumorigenesis, stabilize replication forks and inhibit inaccurate repair. Recent advances have identified endogenous aldehydes as possible culprits of DNA damage that may induce the phenotypes seen in patients with Fanconi anaemia.

Full Text Available Aim. We determined the prevalence of anaemia and evaluated markers of iron homeostasis in a cohort of HIV patients. Methods. A comparative cross-sectional study on 319 participants was carried out at the Tamale Teaching Hospital from July 2013 to December 2013, 219 patients on HAART (designated On-HAART and 100 HAART-naive patients. Data gathered include sociodemography, clinical history, and selected laboratory assays. Results. Prevalence of anaemia was 23.8%. On-HAART participants had higher CD4/CD3 lymphocyte counts, Hb, HCT/PCV, MCV, MCH, iron, ferritin, and TSAT (P<0.05. Hb, iron, ferritin, and TSAT decreased from grade 1 to grade 3 anaemia and CD4/CD3 lymphocyte count was lowest in grade 3 anaemia (P<0.05. Iron (P=0.0072 decreased with disease severity whilst transferrin (P=0.0143 and TIBC (P=0.0143 increased with disease severity. Seventy-six (23.8% participants fulfilled the criteria for anaemia, 86 (26.9% for iron deficiency, 41 (12.8% for iron deficiency anaemia, and 17 (5.3% for iron overload. The frequency of anaemia was higher amongst participants not on HAART (OR 2.6 for grade 1 anaemia; OR 3.0 for grade 3 anaemia. Conclusion. In this study population, HIV-associated anaemia is common and is related to HAART status and disease progression. HIV itself is the most important cause of anaemia and treatment of HIV should be a priority compared to iron supplementation.

Anaemia is a common side effect of ribavirin (RBV) which is used for the treatment of hepatitis C. Inosine triphosphatase gene polymorphism (C to A) protects against RBV-induced anaemia. The aim of our study was to genotype patients for inosine triphosphatase gene polymorphism rs1127354 SNP (CC or CA) and associate treatment-induced anaemia with gene expression profile and genotypes. We used 67 hepatitis C patients with available gene expression, clinical, laboratory data and whole-blood samples. Whole blood was used to determine inosine triphosphatase gene polymorphism rs1127354 genotypes (CC or CA). The cohort with inosine triphosphatase gene polymorphism CA genotype revealed a distinct pattern of protection against anaemia and a lower drop in haemoglobin. A variation in the propensity of CC carriers to develop anaemia prompted us to look for additional predictors of anaemia during pegylated interferon (PEG-IFN) and RBV. Pretreatment blood samples of patients receiving a full course of PEG-IFN and RBV were used to assess expression of 153 genes previously implicated in host response to viral infections. The gene expression data were analysed according to presence of anaemia and inosine triphosphatase gene polymorphism genotypes. Thirty-six genes were associated with treatment-related anaemia, six of which are involved in the response to hypoxia pathway (HIF1A, AIF1, RHOC, PTEN, LCK and PDGFB). There was a substantial overlap between sustained virological response (SVR)-predicting and anaemia-related genes; however, of the nine JAK-STAT pathway-related genes associated with SVR, none were implicated in anaemia. These observations exclude the direct involvement of antiviral response in the development of anaemia associated with PEG-IFN and RBV treatment, whereas another, distinct component within the SVR-associated gene expression response may predict anaemia. We have identified baseline gene expression signatures associated with RBV-induced anaemia and identified

Haidar, Jemal

2010-08-01

A cross-sectional community-based study with analytic component was conducted among Ethiopian women during June-July 2005 to assess the magnitude of anaemia and deficiencies of iron and folic acid and to compare the factors responsible for anaemia among anaemic and non-anaemic cases. In total, 970 women, aged 15-19 years, were selected systematically for haematological and other important parameters. The overall prevalence of anaemia, iron deficiency, iron-deficiency anaemia, deficiency of folic acid, and parasitic infestations was 30.4%, 50.1%, 18.1%, 31.3%, and 13.7% respectively. Women who had more children aged less than five years but above two years, open-field toilet habits, chronic illnesses, and having intestinal parasites were positively associated with anaemia. Women who had no formal education and who did not use contraceptives were negatively associated with anaemia. The major determinants identified for anaemia were chronic illnesses [adjusted odds ratio (AOR) = 1.1, 95% confidence interval (CI) 1.15-1.55), deficiency of iron (AOR = 0.4, 95% CI 0.35-0.64), and deficiency of folic acid (AOR = 0.5, 95% CI 0.50-0.90). The odds for developing anaemia was 1.1 times more likely among women with chronic illnesses, 60% more likely in the iron-deficient and 40% more likely in the folic acid-deficient than their counterparts. One in every three women had anaemia and deficiency of folic acid while one in every two had iron deficiency, suggesting that deficiencies of both folic acid and iron constitute the major micronutrient deficiencies in Ethiopian women. The risk imposed by anaemia to the health of women ranging from impediment of daily activities and poor pregnancy outcome calls for effective public-health measures, such as improved nutrient supplementation, health education, and timely treatment of illnesses.

Full Text Available BACKGROUND Anaemia in pregnancy has serious adverse effects on the health of the mother and the developing foetus. OBJECTIVES The study aims to estimate the prevalence of anaemia in pregnant woman attending the Nagaon Primary Health Centre (PHC in Barpeta district, Assam. METHODS A cross-sectional study was carried out from 1 April, 2014 to 1 May, 2014. 100 pregnant women attending Nagaon PHC were interviewed using a predesigned and pretested interview schedule followed by a short clinical examination for pallor and laboratory estimation of haemoglobin. Sahli’s (Acid Haematin method was used for haemoglobin estimation. Haemoglobin level below the cut-off 11 g/dL was used to label a pregnant woman as anaemic and further classified as mild (10-10.9 g/dL, moderate anaemia (7-9.9 g/dL and severe anaemia (<7 g/dL. RESULTS 77% women were suffering from anaemia. Out of these, 57 %were mildly anaemic and 20% were moderately anaemic. Women of younger age groups, greater parity, a gap less than 3 years between subsequent pregnancies, less education and practising Hinduism had a greater prevalence of anaemia. CONCLUSION Awareness about the serious consequences that anaemia can lead to and advocacy of a proper iron-rich diet, regular intake of IFA tablets and purification of water to prevent infestation by parasites can help in reduction of anaemia.

Anaemia in pregnant women is a public health problem, especially in developing countries. The aim of this study was to assess the prevalence and related risk factors of anaemia during pregnancy in a large multicentre retrospective study (n = 44,002) and to determine the adverse pregnancy outcomes in women with or without anaemia. The study is a secondary data analysis of a retrospective study named "Gestational diabetes mellitus Prevalence Survey (GPS) study in China". Structured questionnaires were used to collect socio-demographic characteristics, haemoglobin levels and pregnancy outcomes from all the participants. Anaemia in pregnancy is defined as haemoglobin anaemia and associated adverse pregnancy outcomes. The overall prevalence of anaemia was 23.5%. Maternal anaemia was significantly associated with maternal age ≥ 35 years (AOR = 1.386), family per capita monthly incomepregnancy BMI pregnancy outcomes, including GDM, polyhydramnios, preterm birth, low birth weight (anaemia than those without. The results indicated that anaemia continues to be a severe health problem among pregnant women in China. Anaemia is associated with adverse pregnancy outcomes. Pregnant women should receive routine antenatal care and be given selective iron supplementation when appropriate.

This prospective study was carried out between June 2005 and June 2006, to determine the prevalence and determinants of anaemia among pregnant women attending a tertiary Sahelian Hospital in Northeastern Nigeria. A total of 1,040 pregnant women enrolled at their first antenatal visit were monitored through pregnancy for anaemia. The overall prevalence of anaemia, malaria parasitaemia and schistosomiasis was 72.0%, 22.1% and 3.8%, respectively. Mild, moderate and severe anaemia constituted 31.8%, 39.4% and 0.9%, respectively. Anaemia was most common among the multipara and women presenting in late stages of pregnancy. More multipara and primigravidae had malaria parasitaemia than grandmultipara. Schistosomiasis, malaria infestation and a short birth interval as well as illiteracy are additional risk factors for anaemia in pregnancy. This study confirms the high prevalence of anaemia in pregnancy in this area. Appropriate intervention strategies are necessary to reduce the prevalence of anaemia.

Full Text Available BACKGROUND It is well known that diabetes adversely affects the kidneys finally leading to anaemia by various mechanisms. Several studies had postulated that anaemia developing before renal complications has an independent association with microvascular complication in type 2 diabetic patients. The aim of the study is to estimate the prevalence of anaemia in persons with type 2 diabetes mellitus and its role as a risk factor for the presence and the severity of microvascular complication in a populationbased study. MATERIALS AND METHODS This is a cross-sectional study conducted in patients coming to OPD of the Department of General Medicine in Government Vellore Medical College for a duration of 3 months from June 01, 2016, to August 31, 2016. Type 2 DM patients between the age group 20-60 years attending our diabetic clinic of both sex were included in our study. RESULTS From a total of 100 patients, 41% had anaemia including 34% with normochromic normocytic, 65.85% with hyperchromic microcytic anaemia and none of the patient had macrocytic anaemia. Patients who are anaemic had more frequent microvascular complications. There was no significant difference between males and females. The average duration of diabetes has a positive correlation with anaemia. All the microvascular complications like neuropathy, nephropathy and retinopathy had significant association with the presence of anaemia in type 2 patients. Nephropathy had a significant higher frequency compared to others as a complication in type 2 DM. CONCLUSION Our study shows that there is increased prevalence of anaemia in type 2 DM patients and the prevalence of microvascular complications is significantly higher among the diabetic patients with anaemia.

Ischemic pituitary necrosis due to severe postpartum haemorrhage called Sheehan's syndrome is a rare cause of hypopituitarism in the western world, but much more common in developing countries. A 45-year-old female patient being a war refugee from Chechnya with severe anaemia and fatigue was diagnosed at our outpatient department with Sheehan's syndrome after severe postpartum haemorrhage and emergency hysterectomy 15 years ago. Panhypopituitarism was adequately treated with substitution of hydrocortisone, thyroxine and transdermal oestrogen which resulted in haemoglobin increase to nearly normal levels and symptoms improved immediately. Severe anaemia caused by panhypopituitarism shows the importance of the hormonal system for erythropoiesis. Clinical and basic scientific evidence indicates thyroidal hormones to be the main cause.

Secondary myelodysplastic syndrome and acute myelogenous leukemia (sMDS/sAML) are the most serious secondary events occurring after immunosuppressive therapy in patients with aplastic anemia. Here we evaluate the outcome of hematopoietic stem cell transplantation (HSCT) in 17 children and young adults with sMDS/sAML after childhood aplastic anemia. The median interval between the diagnosis of aplastic anemia and the development of sMDS/sAML was 2.9 years (range, 1.2 to 13.0 years). At a median age of 13.1 years (range, 4.4 to 26.7 years), patients underwent HSCT with bone marrow (n = 6) or peripheral blood stem cell (n = 11) grafts from HLA-matched sibling donors (n = 2), mismatched family donors (n = 2), or unrelated donors (n = 13). Monosomy 7 was detected in 13 patients. The preparative regimen consisted of busulfan, cyclophosphamide, and melphalan in 11 patients and other agents in 6 patients. All patients achieved neutrophil engraftment. The cumulative incidence of grade II-IV acute graft-versus-host disease (GVHD) was 47%, and that of chronic GVHD was 70%. Relapse occurred in 1 patient. The major cause of death was transplant-related complication (n = 9). Overall survival and event-free survival at 5 years after HSCT were both 41%. In summary, this study indicates that HSCT is a curative therapy for some patients with sMDS/sAML after aplastic anemia. Future efforts should focus on reducing transplantation-related mortality.

Full Text Available Background. Maternal anaemia is a worldwide public health problem affecting particularly developing countries. In Burkina Faso, little data is available for rural areas. This study aimed to determine the prevalence of maternal anaemia and the risk factors associated with it in the rural health district of Hounde in Burkina Faso but also to define better control measures of maternal anaemia. Methods. This cross-sectional study conducted in 2010 had a sample of 3,140 pregnant women attending antenatal care in all the 18 primary health care facilities of the district. The women’s characteristics and their knowledge about contraceptives and sexually transmitted infections (STI were collected. Also, physical and gynaecological examination, completed by vaginal, cervix, blood, and stool samplings, were collected. Results. A prevalence of 63.1% was recorded for maternal anaemia. Geophagy rate was 16.3% and vitamin A deficiency 69.3%. In addition, anaemia was independently associated with low education, low brachial perimeter, geophagy, and primigravida. But no statically significant relationship was found between maternal anaemia and infectious diseases or vitamin A deficiency. Conclusion. The magnitude of maternal anaemia was found to be higher in rural Hounde health district and should be addressed by adequate policy including education and the fight against malnutrition.

1998-11-01

A survey was carried out in Khartoum North Ahmed Gasim specialist Hospital for children to identify aetiological factors that lead to incidence of nutritional anaemia among children under under five years of age. The sample consists of 192 patients taken from the hospital wards (experimental group), and 60 healthy children taken from out patient vaccination department of same hospital. A questionnaire was used as a tool for collection data regarding children and their families with emphasis to general information, socio-economic information, dietary information, anthropometric information, medical history and laboratory investigations including haemoglobin, hematocrit (PCV)%, peripheral blood picture, serum ferritin, serum folate and serum B{sup 12}. Results show no correlation between anaemia and age R(0.1048) p<0.148 and there was no significant difference between anaemia and sex p<(0.104). There is a high significant difference between control and experimental group for Hb and PCV (p<0.00). Aetiological factors related to nutritional anaemia are: poor intake as a supplement or weaning food was poor in iron and folate content. Weaning is sudden because of pregnancy, insufficient milk, mother or child illness and also other causes: low income and many mouths to feed, crowded and unhealthy living conditions, some families had latrines in their houses while others hadn`t. Drinking water is brought from a far distance. The most prevailing type of anaemia is iron deficiency about 26% followed by megaloblastic (10.69%). Which is due to folate deficiency (6.41%), folate and B{sup 1}2 deficiency. Some children affected had mixed deficiency anaemia (3.182). Iron deficiency without anaemia was common among healthy children (control) 22.8%. Some recommendations were set for the improvement of the existing situation e.g. health education, nutrition education with emphasis on intake of supplements and weaning diets rich in iron and folate.

2006-11-01

Full Text Available Abstract Background A survey in Kumasi, Ghana found a marked Plasmodium falciparum prevalence difference between two neighbouring communities (Moshie Zongo and Manhyia. The primary objective of this follow-up study was to determine whether this parasite rate difference was consistent over time. Secondary objectives were to compare prevalences of clinical malaria, anaemia, intestinal parasite infections, and malnutrition between these communities; and to identify potential risk factors for P. falciparum infection and anaemia. Methods A cross-sectional house-to-house survey of P. falciparum parasitaemia, clinical malaria, anaemia, anthropometric indices, and intestinal helminths was conducted in April-May 2005. Data collection included child and household demographics, mosquito avoidance practices, distance to nearest health facility, child's travel history, symptoms, and anti-malarial use. Risk factors for P. falciparum and anaemia (Hb Results In total, 296 children were tested from 184 households. Prevalences of P. falciparum, clinical malaria, anaemia, and stunting were significantly higher in Moshie Zongo (37.8%, 16.9%, 66.2% and 21.1%, respectively compared to Manhyia (12.8%, 3.4%, 34.5% and 7.4%. Of 197 children tested for helminths, four were positive for Dicrocoelium dendriticum. Population attributable risks (PAR% of anaemia were 16.5% (P. falciparum and 7.6% (malnutrition. Risk factors for P. falciparum infection were older age, rural travel, and lower socioeconomic status. Risk factors for anaemia were P. falciparum infection, Moshie Zongo residence, male sex, and younger age. Conclusion Heterogeneities in malariometric indices between neighbouring Kumasi communities are consistent over time. The low helminth prevalence, and the twofold higher PAR% of anaemia attributable to P. falciparum infection compared to malnutrition, indicate the importance of malaria as a cause of anaemia in this urban population.

Splenic dysfunction is a major feature of sickle cell disease (SCD) and can manifest as acute splenic sequestration crisis (ASSC), which is the earliest life-threatening complication seen in patients with SCD. Aplastic crisis is another potentially deadly complication of sickle cell disease that develops when erythrocyte production temporarily drops. Infection with parvovirus B-19 frequently causes aplastic crises. These two complications are known to be mutually exclusive due to their classic presentation signs and symptoms but there have been few cases where a patient can have concomitant presentation of both phenomena, which can result in a fatal outcome. These few cases force us to rethink the etiology and subsequent management guidelines of these complications. We present to you a case of an unfortunate 23-year-old female who had both complications occurring at the same time, resulting in death.

Full Text Available Anaemia is known to have an impact on child development and mortality and is a severe public health problem in most countries in sub-Saharan Africa. We investigated the consistency between ecological and individual-level approaches to anaemia mapping by building spatial anaemia models for children aged ≤15 years using different modelling approaches. We aimed to (i quantify the role of malnutrition, malaria, Schistosoma haematobium and soil-transmitted helminths (STHs in anaemia endemicity; and (ii develop a high resolution predictive risk map of anaemia for the municipality of Dande in northern Angola. We used parasitological survey data for children aged ≤15 years to build Bayesian geostatistical models of malaria (PfPR≤15, S. haematobium, Ascaris lumbricoides and Trichuris trichiura and predict small-scale spatial variations in these infections. Malnutrition, PfPR≤15, and S. haematobium infections were significantly associated with anaemia risk. An estimated 12.5%, 15.6% and 9.8% of anaemia cases could be averted by treating malnutrition, malaria and S. haematobium, respectively. Spatial clusters of high risk of anaemia (>86% were identified. Using an individual-level approach to anaemia mapping at a small spatial scale, we found that anaemia in children aged ≤15 years is highly heterogeneous and that malnutrition and parasitic infections are important contributors to the spatial variation in anaemia risk. The results presented in this study can help inform the integration of the current provincial malaria control programme with ancillary micronutrient supplementation and control of neglected tropical diseases such as urogenital schistosomiasis and STH infections.

Inequitable access to healthcare has a profound impact on the health of marginalised groups that typically suffer an excess burden of infectious disease morbidity and mortality. The Yanomami are traditionally semi-nomadic people living in widely dispersed communities in Amazonian Venezuela and Brazil. Only communities living in the vicinity of a health post have relatively constant access to healthcare. To monitor the improvement in the development of Yanomami healthcare a cross-sectional survey of 183 individuals was conducted to investigate malaria and anaemia prevalence in communities with constant and intermittent access to healthcare. Demographic and clinical data were collected. Malaria was diagnosed by microscopy and haemoglobin concentration by HemoCue. Prevalence of malaria, anaemia, splenomegaly, fever and diarrhoea were all significantly higher in communities with intermittent access to healthcare (anaemia 80.8% vs. 53.6%, P<0.001; malaria 18.2% vs. 6.0%, P=0.013; splenomegaly 85.4% vs.12.5%, P<0.001; fever 50.5% vs. 28.6%, P=0.003; diarrhoea 30.3% vs.10.7% P=0.001). Haemoglobin level (10.0 g/dl vs. 11.5 g/dl) was significantly associated with access to healthcare when controlling for age, sex, malaria and splenomegaly (P=0.01). These findings indicate a heavy burden of anaemia in both areas and the need for interventions against anaemia and malaria, along with more frequent medical visits to remote areas.

The adaptive response of mouse tumours to anaemia and retransfusion

Exchange transfusion methods have been developed to alter the haematocrit of tumour-bearing mice. The effects of anaemia and its correction by blood transfusion on the radiosensitivity of two mouse tumours (SCCVII/St and RIF-1) were studied using excision, in vivo/in vitro assay. Acute reduction in haematocrit caused a high degree of radioresistance equivalent to an increase in the hypoxic fractions by factors of 10 (SCCVII/St) and 30 (RIF-1). As the duration of anaemia was prolonged, radioresistance was lost until within about 6 h normal radiosensitivity was observed even though the anaemia persisted. The restoration of the normal haematocrit by red blood cell transfusion after 24 h of anaemia caused increased radiosensitivity equivalent to a reduction in the hypoxic fraction by factors of 5 (SCCVII/St) and 10 (RIF-1), but again the effect was transient and normal radiosensitivity re-established within 24-48 h of retransfusion. Measurements of 14 C misonidazole (MISO) binding to RIF-1 tumours after these procedures indicated changes in the number of hypoxic cells which were qualitatively almost identical to those using the cell survival endpoint, leading to the belief that changes in oxygenation were reponsible for the altered radiosensitivity.

Iron deficiency is a common nutritional deficiency amongst women of childbearing age. Peri-partum iron deficiency anaemia is associated with significant maternal, foetal and infant morbidity. Current options for treatment include oral iron, which can be ineffective and poorly tolerated, and red blood cell transfusions, which carry an inherent risk and should be avoided. Ferric carboxymaltose is a modern treatment option. The study was designed to assess the safety and efficacy of intravenous ferric carboxymaltose for correction of iron deficiency anaemia in pregnant women. A prospective study was conducted at Institute of Kidney Disease and Research Centre, Ahmedabad from January 2014 to December 2016. Antenatal women (108) with iron deficiency anaemia were the study subjects. Socio-demographic profile was recorded and anaemia was assessed based on recent haemoglobin reports. Iron deficiency was diagnosed on basis of serum ferritin value. Intravenous ferric carboxymaltose as per total correction dose (maximum 1500mg) was administered to all women; the improvement in haemoglobin levels were assessed after 3 weeks of total dose infusion. Most of the women(n= 45, 41.7%), were in the age group of 27-30 years. Most of the women (n = 64, 59.3%) had moderate anaemia as per WHO guidelines. Mean haemoglobin levels significantly increased over a period of 3 weeks after Ferric carboxymaltose administrationand no serious life threatening adverse events were observed. Intravenous ferric carboxymaltose was safe and effective in pregnent women with iron deficiency anaemia.

Directory of Open Access Journals (Sweden)

Paramatma Singh

2014-12-01

Full Text Available Background: About one-third of the global population is anaemic. WHO has estimated that prevalence of anaemia in pregnant women is 18% in developed countries and relatively high 56% in developing countries. Prevalence of anaemia in South East Asian countries is highest in the world. WHO estimates that even among the South East Asian countries, India has the highest prevalence of anaemia. Aims & Objectives: To determine the prevalence of anaemia among pregnant women and to determine association of anaemia with its socio-demographic factors. Material & Methods: A descriptive cross sectional study was conducted among pregnant women 2nd trimester onwards who came to ante natal clinic of obstetrics and gynaecology department during January-March 2014 by using pre-designed, pretested schedule. A total of 300 pregnant women were clinically examined. Written consent was taken. Haemoglobin estimation was done by Cyanmethaemoglobin method and anaemia was graded according to WHO criteria. Statistical analysis was done using Microsoft Excel 2007 and SPSS Version 17. Results: Overall prevalence of anaemia among the pregnant women was found to be 58.3%. It was seen that 31% of women were illiterate and 38.7% of them belong to upper middle class. Factors such as level of education of women, occupation and consumption of Iron Folic Acid were found to be significantly associated with prevalence of anaemia in pregnancy. Conclusion: A very high prevalence of anaemia in pregnancy needs awareness about late marriage, birth spacing, one or two child norm, antenatal care, green leafy vegetable in diet, mandatory regular supply of IFA tablets to adolescent and pregnant women along with correction of other nutritional deficiencies.

Pathophysiology and management of thrombocytopenia in bone marrow failure: possible clinical applications of TPO receptor agonists in aplastic anemia and myelodysplastic syndromes

Aplastic anemia is a bone marrow failure syndrome that causes pancytopenia and can lead to life-threatening complications. Bone marrow transplantation remains the standard of care for younger patients and those with a good performance status but many patients may not have a suitable donor. Immunosuppressive therapy is able to resolve cytopenias in a majority of patients with aplastic anemia but relapses are not uncommon and some patients remain refractory to this approach. Patients may require frequent blood and platelet transfusion support which is expensive and inconvenient. Life-threatening bleeding complications still occur despite prophylactic platelet transfusion. Thrombopoietin (TPO) mimetics, such as romiplostim and eltrombopag, were developed to treat patients with refractory immune thrombocytopenia but are now being investigated for the treatment of bone marrow failure syndromes. TPO is the main regulator for platelet production and its receptor (c-Mpl) is present on megakaryocytes and hematopoietic stem cells. Trilineage hematopoietic responses were observed in a recent clinical trial using eltrombopag in patients with severe aplastic anemia refractory to immunosuppression suggesting that these agents can provide a new therapeutic option for enhancing blood production. In this review, we discuss these recent results and ongoing investigation of TPO mimetics for aplastic anemia and other bone marrow failure states like myelodysplastic syndromes. Clonal evolution or progression to acute myeloid leukemia remains a concern when using these drugs in bone marrow failure and patients should only be treated in the setting of a clinical trial.

To determine the prevalence of anaemia in antenatal clinic attendees; to investigate the effects of parity, age, gravidity, previous abortions, child spacing and other factors on the prevalence of anaemia in pregnancy. This was a retrospective and cross-sectional study. Antenatal records of 2287 pregnant women attending 40 public healthcare centres from January 2000 to December 2005 in Trinidad and Tobago were used. Data pertaining to the investigated variables were recorded. The national prevalence of anaemia was calculated and chi-square tests, odds ratios and logistic regression were used to assess the relationship between anaemia and each variable. The prevalence of anaemia was 15.3% (95% CI 13.4%, 16.6%). No significant difference in the prevalence of anaemia was found among the different clinics or counties. At the first haemoglobin reading, age was inversely related to the presence of anaemia, whereas gestational age at first visit was directly related. At the final haemoglobin reading, parity, gravidity, and previous spontaneous abortions were directly related to the prevalence of anaemia, while the number of visits was inversely related. Age was inversely associated to the severity of anaemia while gravidity was directly related. The prevalence of anaemia decreased by 18.7% from 1967. Despite this positive indication, women under 24 years and those commencing antenatal care after the first trimester are still at a higher risk for developing anaemia. Early commencement of antenatal care and close monitoring of the risk groups identified should be strongly advocated.

Anaemia, in particular due to iron deficiency, is common in pregnancy with associated negative outcomes for mother and infant. However, there is evidence of significant variation in management. The objectives of this review of systematic reviews were to analyse and summarise the evidence base, identify gaps in the evidence and develop a research agenda for this important component of maternity care. Multiple databases were searched, including MEDLINE, EMBASE and The Cochrane Library. All systematic reviews relating to interventions to prevent and treat anaemia in the antenatal and postnatal period were eligible. Two reviewers independently assessed data inclusion, extraction and quality of methodology. 27 reviews were included, all reporting on the prevention and treatment of anaemia in the antenatal (n = 24) and postnatal periods (n = 3). Using AMSTAR as the assessment tool for methodological quality, only 12 of the 27 were rated as high quality reviews. The greatest number of reviews covered antenatal nutritional supplementation for the prevention of anaemia (n = 19). Iron supplementation was the most extensively researched, but with ongoing uncertainty about optimal dose and regimen. Few identified reviews addressed anaemia management post-partum or correlations between laboratory and clinical outcomes, and no reviews reported on clinical symptoms of anaemia. The review highlights evidence gaps including the management of anaemia in the postnatal period, screening for anaemia, and optimal interventions for treatment. Research priorities include developing standardised approaches to reporting of laboratory outcomes, and information on clinical outcomes relevant to the experiences of pregnant women.

High renal uptake on bone marrow scan with indium-111 chloride is often shown in patients with bone marrow abnormality. We evaluated the renal uptake on bone marrow scan in 27 cases of aplastic anemia, 20 cases of myelodysplastic syndrome (MDS) and 10 cases of other diseases. The high renal uptake was observed in patients not only with aplastic anemia but also with MDS. The renal uptake correlated with blood transfusion units, unsaturated iron binding capacity (UIBC), blood pool imaging and bone marrow uptake. The renal uptake correlated with UIBC better than with the blood transfusion units. Following mechanism of the renal uptake is proposed that frequent blood transfusion makes low UIBC, and the low UIBC causes the failure to chelate indium with transferrin. The fast blood clearance of un-chelated indium via kidneys is followed. Hypoplastic bone marrow may also play an important role for the high renal uptake because all patients with the high renal uptake could not be explained by above mentioned mechanism. Caution should be paid to the scans with the high renal uptake because both aplastic anemia and MDS patients show the high renal uptake. (author)

Full Text Available Human parvovirus (HPV B19 induced aplastic crisis in a family leading to the diagnosis of hereditary spherocytosis (HS is a very rare condition being barely reported in the literature. We herein report a 4-year-old girl, her brother, and their mother who all presented with progressive pallor and jaundice after a febrile illness. The HPV B19 was diagnosed using polymerase chain reaction (PCR and positive serology for specific anti-HPV B19 IgM. They were further diagnosed with having HS. The clinical importance of this report is that in the case of an abrupt onset of unexplained severe anemia and jaundice, one should consider underlying hemolytic anemias mostly hereditary spherocytosis complicated by HPV B19 aplastic crisis. Herein, we report the occurrence of this condition, simultaneously in three members of a family. The distinguished feature of this report is that all affected family members developed some degrees of transient pancytopenia, not only anemia, all simultaneously in the course of their disease.

Full Text Available BACKGROUND: Studies conducted in high income countries have shown that anaemia is a common medical condition among older people, but such data are scarce in Africa. The objectives of this study were to estimate the prevalence, types, risk factors and clinical correlates of anaemia in older people. METHODS: Participants were aged (≥ 50 years recruited from a general population cohort from January 2012 to January 2013. Blood samples were collected for assessing hemoglobin, serum ferritin, serum vitamin B12, serum folate, C-reactive protein, malaria infection and stool samples for assessment of hookworm infection. HIV status was assessed using an algorithm for HIV rapid testing. Questionnaires were used to collect data on sociodemographic characteristics and other risk factors for anaemia. RESULTS: In total, 1449 people participated (response rate 72.3%. The overall prevalence of anaemia was 20.3 % (95% CI 18.2-22.3%, and this was higher for males (24.1%, 95% CI=20.7-27.7% than females (17.5%, 95% CI=15.0-20.1%. In males, the prevalence of anaemia increased rapidly with age almost doubling between 50 and 65 years (p-trend<0.001. Unexplained anaemia was responsible for more than half of all cases (59.7%. Anaemia was independently associated with infections including malaria (OR 3.49, 95% CI 1.78-6.82, HIV (OR 2.17, 1.32-3.57 heavy hookworm infection (OR 3.45, 1.73-6.91, low fruit consumption (OR 1.55, 1.05-2.29 and being unmarried (OR 1.37 , 95% CI 1.01-1.89. However, the odds of anaemia were lower among older people with elevated blood pressure (OR 0.47, 95% CI 0.29-0.77. CONCLUSION: Anaemia control programmes in Uganda should target older people and should include interventions to treat and control hookworms and educational programs on diets that enhance iron absorption. Clinicians should consider screening older people with HIV or malaria for anaemia. Further studies should be done on unexplained anaemia and serum ferritin levels that predict

Anaemia during pregnancy is an important public health problem. We investigated whether the association between maternal anaemia during pregnancy and adverse perinatal outcomes differed between nulliparous and multiparous women. A retrospective population-based cohort study was conducted using data on all singleton births (n = 290 662) recorded in the Finnish Medical Birth Register during 2006-10. Maternal anaemia was defined as a maternal haemoglobin level of anaemia and adverse outcomes was assessed by logistic regression analysis. The prevalence of anaemia during pregnancy was 2.5% among nulliparous women and 2.3% among multiparous women. Among nulliparous women, anaemia was not associated with adverse perinatal outcomes. Among multiparous women, anaemia was associated with preterm delivery (adjusted odds ratio [aOR] 1.32, [95% CI 1.14, 1.53]), SGA (aOR 1.27, [95% CI 1.04, 1.55]), and admission to neonatal intensive care (aOR 1.23, [95% CI 1.10, 1.38]); there was a trend towards increased odds of major congenital anomalies (aOR 1.15, [95% CI 0.99, 1.34]). These data underscore that maternal anaemia is associated with several adverse perinatal outcomes. This association was, however, confined to multiparous women. Future research should explore in detail the timing of anaemia in these associations. © 2014 John Wiley & Sons Ltd.

Full Text Available Background: About one-third of the global population is anaemic. WHO has estimated that prevalence of anaemia in pregnant women is 18% in developed countries and relatively high 56% in developing countries. Prevalence of anaemia in South East Asian countries is highest in the world. WHO estimates that even among the South East Asian countries, India has the highest prevalence of anaemia. Aims & Objectives: To determine the prevalence of anaemia among pregnant women and to determine association of anaemia with its socio-demographic factors. Material & Methods: A descriptive cross sectional study was conducted among pregnant women 2nd trimester onwards who came to ante natal clinic of obstetrics and gynaecology department during January-March 2014 by using pre-designed, pretested schedule. A total of 300 pregnant women were clinically examined. Written consent was taken. Haemoglobin estimation was done by Cyanmethaemoglobin method and anaemia was graded according to WHO criteria. Statistical analysis was done using Microsoft Excel 2007 and SPSS Version 17. Results: Overall prevalence of anaemia among the pregnant women was found to be 58.3%. It was seen that 31% of women were illiterate and 38.7% of them belong to upper middle class. Factors such as level of education of women, occupation and consumption of Iron Folic Acid were found to be significantly associated with prevalence of anaemia in pregnancy. Conclusion: A very high prevalence of anaemia in pregnancy needs awareness about late marriage, birth spacing, one or two child norm, antenatal care, green leafy vegetable in diet, mandatory regular supply of IFA tablets to adolescent and pregnant women along with correction of other nutritional deficiencies.

The objective of the study was to assess the prevalence of anaemia in the immediate postpartum period (48-72hours), determine the risk factors and the value of haemoglobin before birth to reduce postpartum anaemia. A prospective, observational and longitudinal study that included 1,426 women who delivered consecutively and agreed to participate in the study. Different variables, analytical, epidemiological, foetal and maternal symptoms were studied. The prevalence of anaemia in the postpartum period was 49.7%. The most important risk factors were antepartum anaemia and type of delivery. The types of delivery most influencing postpartum anaemia were, forceps (82.3%), the ventouse 67%, cesarean section (58,2%) and vaginal delivery (37.2%). In the multivariate study was found as the most important independent risk factors, the haemoglobin in the delivery day (OR 6.16, CI: 3.73 to 10.15) and instrumental delivery (OR: 4.61, CI: 3.44 to 6, 19). Other independent risk factors were haemoglobin in the third trimester, episiotomy and perineal tears, ethnicity, birth weight, parity and intra/postpartum complications. Anaemia in the immediate postpartum is a prevalent problem. The factors most associated postpartum anaemia were antepartum anaemia and instrumental delivery. If patients arrive at the day of delivery with haemoglobins≥12,6g/dl and were restricted to necessary instrumented deliveries and cesarean sections, episiotomies and we could avoid perineal tears we can decrease anaemia in the immediate postpartum period very significantly.

To assess reproductive risk factors for anaemia among pregnant women in urban and rural areas of India. The International Institute of Population Sciences, India, carried out third National Family Health Survey in 2005-2006 to estimate a key indicator from a sample of ever-married women in the reproductive age group 15-49 years. Data on various dimensions were collected using a structured questionnaire, and anaemia was measured using a portable HemoCue instrument. Anaemia prevalence among pregnant women was compared between rural and urban areas using chi-square test and odds ratio. Multinomial logistic regression analysis was used to determine risk factors. Anaemia prevalence was assessed among 3355 pregnant women from rural areas and 1962 pregnant women from urban areas. Moderate-to-severe anaemia in rural areas (32.4%) is significantly more common than in urban areas (27.3%) with an excess risk of 30%. Gestational age specific prevalence of anaemia significantly increases in rural areas after 6 months. Pregnancy duration is a significant risk factor in both urban and rural areas. In rural areas, increasing age at marriage and mass media exposure are significant protective factors of anaemia. However, more births in the last five years, alcohol consumption and smoking habits are significant risk factors. In rural areas, various reproductive factors and lifestyle characteristics constitute significant risk factors for moderate-to-severe anaemia. Therefore, intensive health education on reproductive practices and the impact of lifestyle characteristics are warranted to reduce anaemia prevalence. © 2014 John Wiley & Sons Ltd.

2008-08-01

Full Text Available Abstract Background Anaemia may increase risk of dementia or cognitive decline. There is also evidence that high haemoglobin levels increase risk of stroke, and consequently possible cognitive impairment. The elderly are more at risk of developing dementia and are also more likely to suffer from anaemia, although there is relatively little longitudinal literature addressing this association. Methods To evaluate the evidence for any relationship between incident cognitive decline or dementia in the elderly and anaemia or haemoglobin level, we conducted a systematic review and meta-analyses of peer reviewed publications. Medline, Embase and PsychInfo were searched for English language publications between 1996 and 2006. Criteria for inclusion were longitudinal studies of subjects aged ≥65, with primary outcomes of incident dementia or cognitive decline. Other designs were excluded. Results Three papers were identified and only two were able to be combined into a meta-analysis. The pooled hazard ratio for these two studies was 1.94 (95 percent confidence intervals of 1.32–2.87 showing a significantly increased risk of incident dementia with anaemia. It was not possible to investigate the effect of higher levels of haemoglobin. Conclusion Anaemia is one factor to bear in mind when evaluating risk of incident dementia. However, there are few data available and the studies were methodologically varied so a cautionary note needs to be sounded and our primary recommendation is that further robust research be carried out.

Anaemia in pregnancy is associated with adverse maternal and fetal outcome. Unfortunately, in developing countries its prevalence has continued to rise. To improve the situation, iron supplement is routinely prescribed during pregnancy. We therefore examine the impact of the intervention as being currently practised in our clinical setting. In total, 255 prenatal clinic attendees who had more than 8 weeks of prescribed iron supplements were sampled. Data was obtained on their socio-demographic features, haemoglobin concentration at booking, compliance with iron supplements and third trimester haemoglobin value. Observed iron supplementation compliance rate was 184(72.2%). There was a significant drop in mean haemoglobin (Hb) concentration between the two time points (booking Hb: 32.56±2.99; third trimester Hb: 31.67±3.01; mean diff: 0.89±3.04; t = 4.673; 95% CI= 0.52-1.27; p= Anaemia increased from 132(51.8%) to 150(58.8%) by the third trimester. Increase in anaemia occurred in both iron-compliant and non-compliant groups. Non-compliance however had higher odds of predicting anaemia by the third trimester (OR: 1.83; 95% CI: 1.03-3.26; p: 0.04). Although iron supplementation is still a good intervention in developing countries, it is not sufficient to reduce overall prevalence of anaemia by the third trimester. There is a need to look beyond the approach and reinforce the importance of better feeding practices, food fortification and reduced frequency of pregnancies.

Background Anaemia is highly prevalent in children of developing countries. It is associated with impaired physical growth and mental development. Palmar pallor is recommended at primary level for diagnosing it, on the basis of few studies. The objective of the study was to systematically assess the accuracy of clinical signs in the diagnosis of anaemia in children. Methods A systematic review on the accuracy of clinical signs of anaemia in children. We performed an Internet search in various databases and an additional reference tracking. Studies had to be on performance of clinical signs in the diagnosis of anaemia, using haemoglobin as the gold standard. We calculated pooled diagnostic likelihood ratios (LR's) and odds ratios (DOR's) for each clinical sign at different haemoglobin thresholds. Results Eleven articles met the inclusion criteria. Most studies were performed in Africa, in children underfive. Chi-square test for proportions and Cochran Q for DOR's and for LR's showed heterogeneity. Type of observer and haemoglobin technique influenced the results. Pooling was done using the random effects model. Pooled DOR at haemoglobin outliers. Conclusion This meta-analysis did not document a highly accurate clinical sign of anaemia. In view of poor performance of clinical signs, universal iron supplementation may be an adequate control strategy in high prevalence areas. Further well-designed studies are needed in settings other than Africa. They should assess inter-observer variation, performance of combined clinical signs, phenotypic differences, and different degrees of anaemia. PMID:16336667

Full Text Available The creation of a telemedicine, tele-expertise platform opens a new challenge within the European Network for Rare and Congenital Anaemias (ENERCA; www.enerca.org. This is a cornerstone in the field of rare anaemias, in which national expertise is usually scarce and a significant number of patients remain undiagnosed. Experts in rare diseases are specially needed of shared knowledge platforms offering the possibility of a faster and more accurate diagnosis and the availability of a better patients’ follow-up. The platform developed by e- ENERCA will be user friendly and intuitive so it will be used by the majority of professionals without requiring a specific formation. The idea of inter professional consultation is to bring medical experts together for collaborative involvement in activities that maximize the benefits and improvement in patient care.

Full Text Available Abstract Background Early diagnosis of anaemia represents an important task within primary care settings. This study reports on the frequency of new cases of anaemia among patients attending rural primary care settings in Crete (Greece and to offer an estimate of iron deficiency anaemia (IDA frequency in this study group. Methods All patients attending the rural primary health care units of twelve general practitioners (GPs on the island of Crete for ten consecutive working days were eligible to participate in this study. Hemoglobin (Hb levels were measured by portable analyzers. Laboratory tests to confirm new cases of anaemia were performed at the University General Hospital of Heraklion. Results One hundred and thirteen out of 541 recruited patients had a low value of Hb according to the initial measurement obtained by the use of the portable analyzer. Forty five (45.5% of the 99 subjects who underwent laboratory testing had confirmed anaemia. The mean value of the Hb levels in the group with confirmed anaemia, as detected by the portable analyzer was 11.1 g/dl (95% Confidence Interval (CI from 10.9 to 11.4 and the respective mean value of the Hb levels obtained from the full blood count was 11.4 g/dl (95% CI from 11.2 to 11.7 (P = 0.01. Sixteen out of those 45 patients with anaemia (35.6% had IDA, with ferritin levels lower than 30 ng/ml. Conclusion Keeping in mind that this paper does not deal with specificity or sensitivity figures, it is suggested that in rural and remote settings anaemia is still invisible and point of care testing may have a place to identify it.

Pregnancy during the adolescent period is challenging mainly because of the nutritional demands of both the adolescent and pregnancy period. The risk for anaemia increases especially in developing countries such as Ghana where malaria is endemic and the practice of pica is common. In this study, we sought to determine the prevalence of anaemia, pica practice and malaria infection among pregnant adolescent girls and assess the extent to which these factors are associated. Two hundred and sixty five (265) pregnant adolescent girls were recruited from three hospitals in Accra. Haemoglobin levels, malaria infection and the practice of pica were assessed. Pearson's Chi squared tests were used to determine associations and logistic regression analysis was used to determine the odds of being anaemic. Significance was set at p≤0.05. Anaemia prevalence was 76% with severity ranging from mild (47.8%) to severe (0.8%). About 27.5% were moderately anaemic. Pica was practiced in only 9.1% of the girls. Malaria infection was prevalent in 17.7% of the girls. The logistic regression analysis indicated that pregnant girls with malaria infection were 3.56 times more likely to be anaemic when compared to those without malaria. Also, those who practiced pica were 1.23 times more likely to be anaemic when compared to those who did not practice pica. Anaemia is very prevalent in pregnant adolescent girls and is a public health problem. Drastic measures should be taken to reduce the high prevalence.

Maternal anaemia is a common pregnancy complication in developing countries; however, its epidemiology remains largely unexplored in China. This study was designed to explore the epidemiology and risk factors of anaemia during pregnancy. A prospective cohort study was conducted, using data from a population-based pregnancy-monitoring system in 13 counties in East China (1993-96). Women who delivered singleton infants at 20-44 weeks with at least one haemoglobin assessment during pregnancy were included (n = 164 667). The prevalence of anaemia (haemoglobin pregnancy as well as in each trimester was estimated. Multivariable log-binomial regression models were used to evaluate risk factors. The overall prevalence of anaemia in pregnancy was 32.6%, with substantial variations across trimesters (11.2%, 20.1% and 26.2% in the 1st, 2nd and 3rd trimesters respectively). Risk factors for anaemia included older maternal age, education below junior high school (prevalence rate ratio [RR] 1.10, 95% confidence interval [CI] 1.08, 1.12), farming occupation (1.05, 95% CI 1.03, 1.06), and mild pregnancy-induced hypertension (PIH) (RR 1.09, 95% CI 1.05, 1.13) and severe PIH (RR 1.13, 95% CI 1.06, 1.19). Peri-conception folic acid use was associated with a reduced risk for anaemia in the 1st trimester (RR 0.75, 95% CI 0.72, 0.78). Initiating prenatal care after the 1st trimester was associated with increased risk of anaemia in the 2nd and 3rd trimesters. Our study found anaemia during pregnancy is highly prevalent in this indigenous Chinese population. The risk increases with the severity of hypertensive disorders. Folic acid supplementation during the peri-conception period is associated with reduced risk of 1st trimester anaemia.

Gastric biopsies from 86 patients with pernicious anaemia were examined for Campylobacter like organisms with particular attention to those showing an antral gastritis in addition to the usual pattern of body gastritis. All the patients had chronic atrophic gastritis in the body but Campylobacter like organisms were found at this site in only three patients. Thus the Type A pattern of gastritis (autoimmune) seen in patients with pernicious anaemia is only rarely associated with Campylobacter like organisms. Forty four of these patients had biopsies from body and antrum, 16 showed an antral gastritis of whom only one had Campylobacter like organism present. Twenty five of this latter group of patients were rebiopsied after five years. There was no change in the pattern of gastritis, and the same single patient remained colonised. The frequency of an antral gastritis in patients with pernicious anaemia was 36% yet the frequency of antral colonisation by Campylobacter like organisms was very low (6%). These results show that, as in the body, Campylobacter like organisms are not associated with gastritis when it occurs at this site in pernicious anaemia. The antral gastritis that may accompany body gastritis in pernicious anaemia seems more likely therefore to be an extension of primary type A body gastritis (autoimmune) rather than a secondary type B (chronic) gastritis and, it is argued, the antrum may exhibit resistance to colonisation.

Iron absorption from a simple breakfast meal by a normal adult was done by the whole body counting system and blood radioactivity measurement. Results seem to be in good agreement and both the methods are found to be standard for measurements of iron absorption from food. In iron deficiency anaemia associated with malnutrition improvement of nutritional condition has been found to increase both haemoglobin level and iron absorption possibly by way of improving the ability of intestinal mucosa to absorb more iron from food and by better utilization of iron by erythropoietic system. Thus improvement of nutritional status is a prerequisite to treatment of iron deficiency anaemia.

The 2008 World Health Organization classification proposed a new entity in childhood myelodysplastic syndrome, refractory cytopenia of childhood. However, it is unclear whether this morphological classification reflects clinical outcomes. We retrospectively reviewed bone marrow morphology in 186 children (median age 8 years; range 1-16 years) who were enrolled in the prospective study and received horse antithymocyte globulin and cyclosporine between July 1999 and November 2008. The median follow-up period was 87 months (range 1-146 months). Out of 186 patients, 62 (33%) were classified with aplastic anemia, 94 (49%) with refractory cytopenia of childhood, and 34 (18%) with refractory cytopenia with multilineage dysplasia. Aplastic anemia patients received granulocyte colony-stimulating factor more frequently and for longer durations than other patients (Paplastic anemia, 4 patients with refractory cytopenia of childhood, and 3 patients with refractory cytopenia with multilineage dysplasia. Although the cumulative incidence of total clonal evolution at ten years was not significantly different among the 3 groups, the cumulative incidence of monosomy 7 development was significantly higher in aplastic anemia than in the other groups (P=0.02). Multivariate analysis revealed that only granulocyte colony-stimulating factor administration duration of 40 days or more was a significant risk factor for monosomy 7 development (P=0.02). These findings suggest that even the introduction of a strict morphological distinction from hypoplastic myelodysplastic syndrome cannot eradicate clonal evolution in children with aplastic anemia.

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.

Full Text Available Hemochromatosis is an inherited or secondary disorder caused by excessive iron storage leading to multiple organ damage. We describe 2 patients with diabetes mellitus caused by hemochromatosis secondary to multiple blood transfusions due to severe aplastic anemia. Subject 1, who was diagnosed with severe aplastic anemia at 15 years of age, received multiple red blood cell transfusions before he underwent autologous peripheral blood stem cell transplantation (PBSCT at 22 years of age. At 21 years of age, hyperglycemia was detected with increased hemoglobin A1c and serum ferritin levels, 9.7% and 12,910 ng/mL (normal range, 20–320 ng/mL, respectively. The 24-hour urine C-peptide level was normal with negative antiglutamic acid decarboxylase antibody. Subsequently, metformin and an iron-chelating agent were administered. However, an intensive insulin regimen was necessary 2 years after the onset of diabetes. Subject 2, who was diagnosed with severe aplastic anemia at 2 years of age, received multiple blood transfusions until she underwent haploidentical PBSCT at 13 years of age. At 11 years of age, she developed diabetes mellitus with a high serum ferritin level (12,559.8 ng/mL. She is currently 18 years old and has been treated with an intensive insulin regimen and estrogen/progesterone replacement therapy because of hypogonadotropic hypogonadism. It is presumed that the loss of insulin secretory capacity and insulin resistance played a role in the pathogenesis of diabetes mellitus due to hemochromatosis in these cases.

HIV infection and anaemia are major public-health problems in Africa and are important factors associated with an increased risk of adverse pregnancy outcomes. The objective of this study was to determine the prevalence of HIV infection and anaemia among pregnant women attending antenatal clinics in southeastern Nigeria. To achieve this, a cross-sectional survey was conducted during July 2005-June 2006 using standard techniques. Of 815 pregnant women studied, 31 (3.8%, 95% confidence interval [CI] 2.5-5.1) were HIV-positive. Maternal age and gestational age were not associated with HIV infection (p > 0.05). The prevalence of anaemia (Hb anaemia (Hb prevalence of anaemia was observed among individuals in their second pregnancy trimester (p anaemia are preventable, antenatal care services could serve as a pivotal entry point for simultaneous delivery of interventions for the prevention and control of HIV infection and anaemia in pregnant women.

Full Text Available Abstract Background We report a patient with cytogenetically confirmed Fanconi anaemia with associated diffuse bilateral pulmonary arterio-venous fistulae. This is only the second reported case of diffuse pulmonary arterio-venous fistulae with Fanconi anaemia. Case Presentation A 16 year old Sri Lankan boy, with a cytogenetically confirmed Fanconi anaemia was admitted to University Medical Unit, National Hospital of Sri Lanka for further assessment and treatment. Both central and peripheral cyanosis plus clubbing were noted on examination. The peripheral saturation was persistently low on room air and did not improve with supplementary Oxygen. Contrast echocardiography failed to demonstrate an intra cardiac shunt but showed early crossover of contrast, suggesting the possibility of pulmonary arterio-venous fistulae. Computed tomography pulmonary angiogram was inconclusive. Subsequent right heart catheterisation revealed bilateral diffuse arterio-venous fistulae not amenable for device closure or surgical intervention. Conclusion To our knowledge, this is the second reported patient with diffuse pulmonary arterio-venous fistulae associated with Fanconi anaemia. We report this case to create awareness among clinicians regarding this elusive association. We recommend screening patients with Fanconi anaemia using contrast echocardiography at the time of assessment with transthoracic echocardiogram. Though universal screening may be impossible given the cost constraints, such screening should at least be performed in patients with clinical evidence of desaturation or when a therapeutic option such as haematopoietic stem cell transplantation is considered. Treatment of pulmonary arteriovenous fistulae would improve patient outcome as desaturation by shunting worsens the anaemic symptoms by reducing the oxygen carrying capacity of blood.

To determine the effect of maternal anaemia on pregnancy outcome and describe its impact on infant haemoglobin level in the first 18 months of life, we conducted a prospective study of 617 pregnant women and their children in Benin. Prevalence of maternal anaemia at delivery was 39.5%, and 61.1% of newborns were anaemic at birth. Maternal anaemia was not associated with low birth weight [OR = 1.2 (0.6-2.2)] or preterm birth [OR = 1.3 (0.7-2.4)], whereas the newborn's anaemia was related to maternal anaemia [OR = 1.8 (1.2-2.5)]. There was no association between an infant's haemoglobin level until 18 months and maternal anaemia. However, malaria attacks during follow-up, male gender and sickle cell trait were all associated with a lower infant haemoglobin level until 18 months, whereas good infant feeding practices and a polygamous family were positively associated with a higher haemoglobin level during the first 18 months of life. © 2011 Blackwell Publishing Ltd.

To examine various sociodemographic aspects related to consumption of micronutrient-rich foods like green leafy vegetables (GLV), which will be helpful in modifying dietary habits, a strategy that merits consideration for prevention of anaemia. Cross-sectional study for collecting data on socio-economic and anthropometric (weight, height) variables, Hb, dietary pattern (FFQ) and peripheral smear examination for classifying nutritional and iron-deficiency anaemia (IDA). Three villages near Pune city, Maharashtra, India. Rural women (n 418) of childbearing age (15-35 years). Mean Hb was 11·07 g/dl. Seventy-seven per cent of the women were anaemic (Hb women had nutritional anaemia. Higher prevalence of IDA was associated with several sociodemographic and maternal parameters, but multiple logistic regression analysis showed significant (P lack of awareness about different recipes for GLV. Our findings highlight that low consumption of GLV, which are treasures of micronutrients including Fe, is associated with genuine social reasons. This indicates a need for developing action programmes to improve nutritional knowledge and awareness leading to enhanced consumption of Fe-rich foods for preventing anaemia in rural India.

Marcou, Yiola; D'Andrea, Andrew; Jeggo, Penelope A.; Plowman, Piers N.

2001-01-01

Background: Fanconi anaemia is a rare disease associated with cellular sensitivity to chemicals (e.g. mitomycin C and diepoxybutane); variable but mild cellular radiosensitivity has also been reported. Materials and methods: A 32-year-old patient with Fanconi anaemia and tonsillar carcinoma, treated by radiotherapy, was found to exhibit profound clinical radiosensitivity. Confluent, ulcerating oropharyngeal mucositis developed after a conventionally fractionated dose of 34 Gy and healing was incomplete by 2 months after cessation of therapy. Results: Cellular radiosensitivity assays and RPLD studies from this patient did not suggest any major detectable radiosensitivity. Conclusion: There is a discrepancy between the observed clinical radiosensitivity and the usual 'predictive' radiosensitivity assays in this patient with Fanconi anaemia

High renal uptake on bone marrow scan with indium-111 chloride is often shown in patients with bone marrow abnormality. We evaluated the renal uptake on bone marrow scan in 27 cases of aplastic anemia, 20 cases of myelodysplastic syndrome (MDS) and 10 cases of other diseases. The high renal uptake was observed in patients not only with aplastic anemia but also with MDS. The renal uptake correlated with blood transfusion units, unsaturated iron binding capacity (UIBC), blood pool imaging and bone marrow uptake. The renal uptake correlated with UIBC better than with the blood transfusion units. Following mechanism of the renal uptake is proposed that frequent blood transfusion makes low UIBC, and the low UIBC causes the failure to chelate indium with transferrin. The fast blood clearance of un-chelated indium via kidneys is followed. Hypoplastic bone marrow may also play an important role for the high renal uptake because all patients with the high renal uptake could not be explained by above mentioned mechanism. Caution should be paid to the scans with the high renal uptake because both aplastic anemia and MDS patients show the high renal uptake. (author).

Subclinical anaemia of chronic disease in adult patients with cystic fibrosis.

LENUS (Irish Health Repository)

O'connor, T M

2012-02-03

Patients with chronic hypoxaemia develop secondary polycythaemia that improves oxygen-carrying capacity. Therefore, normal haemoglobin and haematocrit values in the presence of chronic arterial hypoxaemia in cystic fibrosis constitute \\'relative anaemia\\'. We sought to determine the cause of this relative anaemia in patients with cystic fibrosis. We studied haematological indices and oxygen saturation in healthy volunteers (n=17) and in adult patients with cystic fibrosis (n=15). Patients with cystic fibrosis had lower resting arterial oxygen saturation when compared with normal volunteers (P<0.0001), and exercise led to a greater reduction in arterial oxygen saturation (P<0.0001). However, haemoglobin and haematocrit values in patients with cystic fibrosis did not significantly differ from normal volunteers. Serum iron (P=0.002), transferrin (P=0.02), and total iron-binding capacity (P=0.01) were lower in patients with cystic fibrosis. There were no significant differences in serum ferritin, percentage iron saturation, serum erythropoietin or red cell volume between the groups. The data presented demonstrate a characteristic picture of anaemia of chronic disease in adult patients with cystic fibrosis, except for normal haemoglobin and haematocrit values. Normal haemoglobin and haematocrit values in patients with cystic fibrosis appear to represent a combination of the effects of arterial hypoxaemia promoting polycythaemia, counterbalanced by chronic inflammation promoting anaemia of chronic disease.

Full Text Available Background: Sickle cell anaemia is an inherited disease in which the red blood cells become rigid and sticky, and change from being disc-shaped to being crescent-shaped. The change in shape is due to the presence of an abnormal form of haemoglobin. This results in severe pain and damage to some organs. Aim and Objective: The study was carried out to determine the levels of cytokine in sickle cell anemia. Material and Methods: Thirty confirmed sickle cell patients in steady state (HbSS-SS and thirty persons with normal haemoglobin (HbAA as well as sixteen sickle cell disease in crises (HbSS-cr between the ages of 15 to 30 years were selected in this study. Cytokines including interleukin 1 beta (IL- 1β, interleukin 2 (IL- 2, interleukin (IL-6, tumour necrosis factor alpha (TNF-α, and interferon gamma (IFN- λ were measured by commercially available ELISA kits. Results: The results obtained showed that the levels of TNF-α and IL-6 in sickle cell anaemia patients in crisis were significantly elevated when compared with sickle cell in steady state (P<0.05. Similarly, the levels of IL-1β, IL-6, and IFN- λ were significantly increased in sickle cell anaemia stable state when compared to HbAA subjects (P<0.05. Conclusion: This may probably implies that cytokine imbalance is implicated in the pathogenesis of sickle cell crisis. Also, cytokines could be used as an inflammatory marker as well as related marker in disease severity and hence therapeutic intervention.

Anaemia is common in malaria. It is important to quantitate the risk of anaemia and to distinguish factors related to the natural history of disease from potential drug toxicity. Individual-patient data analysis based on nine randomized controlled trials of treatments of uncomplicated falciparum malaria from 13 sub-Saharan African countries. Risk factors for reduced haemoglobin (Hb) concentrations and anaemia on presentation and after treatment were analysed using mixed effect models. Eight thousand eight hundred ninety-seven patients (77.0% <5 years-old) followed-up through 28 days treated with artemisinin combination therapy (ACT, 90%, n = 7968) or non-ACT. At baseline, under 5's had the highest risk of anaemia (77.6% vs. 32.8%) and higher parasitaemia (43,938 μl) than older subjects (2784 μl). Baseline anaemia increased the risk of parasitological recurrence. Hb began to fall after treatment start. In under 5's the estimated nadir was ~35 h (range 29-48), with a drop of -12.8% from baseline (from 9.8 g/dl to 8.7 g/dl, p = 0.001); in under 15's, the mean Hb decline between day 0-3 was -4.7% (from 9.4 to 9.0 g/dl, p = 0.001). The degree of Hb loss was greater in patients with high pre-treatment Hb and parasitaemia and with slower parasite reduction rates, and was unrelated to age. Subsequently, Hb increased linearly (+0.6%/day) until day 28, to reach +13.8% compared to baseline. Severe anaemia (<5 g/dl, 2 per 1000 patients) was transient and all patients recovered after day 14, except one case of very severe anaemia associated with parasite recurrence at day 28. There was no systematic difference in Hb concentrations between treatments and no case of delayed anaemia. On presentation with acute malaria young children with high parasitaemia have the highest risk of anaemia. The majority of patients experience a drop in Hb while on treatment as early as day 1-2, followed by a linear increase through follow-up. The degree of the early Hb dip is

Transient engraftment of syngeneic bone marrow after conditioning with high-dose cyclophosphamide and thoracoabdominal irradiation in a patient with aplastic anemia

We describe the clinical course of a 16 year old girl with aplastic anemia who was treated by syngeneic bone marrow transplantation. Engraftment was not obtained by simple infusion of bone marrow without immunosuppression. The patient received a high-dose cyclophosphamide and thoracoabdominal irradiation, followed by second marrow transplantation from the same donor. Incomplete but significant hematologic recovery was observed; however, marrow failure recurred 5 months after transplantation. Since donor and recipient pairs were genotypically identical, graft failure could not be attributed to immunological reactivity of recipient cells to donor non-HLA antigens. This case report implies that graft failure in some cases of aplastic anemia might be mediated by inhibitory cells resistant to cyclophosphamide and irradiation

It is suggested that helminths, particularly hookworm and schistosomiasis, may be important causes of anaemia in pregnancy. We assessed the associations between mild-to-moderate anaemia (haemoglobin >8.0 g/dl and pregnancy in Entebbe, Uganda. The prevalence of anaemia was 39.7%. The prevalence of hookworm was 44.5%, Mansonella perstans 21.3%, Schistosoma mansoni 18.3%, Strongyloides 12.3%, Trichuris 9.1%, Ascaris 2.3%, asymptomatic Plasmodium falciparum parasitaemia 10.9% and HIV 11.9%. Anaemia showed little association with the presence of any helminth, but showed a strong association with malaria (adjusted odds ratio (AOR) 3.22, 95% CI 2.43-4.26) and HIV (AOR 2.46, 95% CI 1.90-3.19). There was a weak association between anaemia and increasing hookworm infection intensity. Thus, although highly prevalent, helminths showed little association with mild-to-moderate anaemia in this population, but HIV and malaria both showed a strong association. This result may relate to relatively good nutrition and low helminth infection intensity. These findings are pertinent to estimating the disease burden of helminths and other infections in pregnancy.

To compare the odds of anaemia in overweight and obese (OVWT) (body mass index (BMI) > or =25) versus non-overweight (non-OVWT) (BMIPeru and Egypt (2000 Demographic and Health Surveys) were analyzed. Data from non-pregnant women ages 18-49 years were used. Logistic regression was used to test whether the odds of anaemia differed by BMI category, controlling for sociodemographic factors. More than half of the women were OVWT in all three countries and the prevalence of OVWT reached 77% in Egypt. Anaemia prevalence was similar across countries (28, 31 and 23% in Egypt, Peru and Mexico respectively). In Egypt, OVWT women had significantly lower odds of anaemia than non-OVWT women (OR=0.78, 95% CI: 0.68, 0.90). Similar results were found in Peru, but the difference was smaller in magnitude (OR=0.83, 95% CI: 0.71, 0.96). In Mexico, there were no differences in the odds of anaemia by BMI group. These findings show that the iron needs of OVWT women in developing countries are not necessarily being met. The intakes of other micronutrients might also be insufficient. Diet quality remains an important issue even among women with sufficient energy intakes.

To determine the prevalence of anaemia during pregnancy in Anuradhapura district and evaluate present screening methods for anaemia. Modified WHO 30 cluster sampling method with increased precision was used to estimate the prevalence of anaemia in the Anuradhapura district, Sri Lanka. Serum haemoglobin was measured using methemoglobin method. Clinical examination was carried out to evaluate the conjunctival method in anaemia screening. Values recorded from haemoglobin colour scale method used in the field antenatal clinics were collected. A total of 990 pregnant women participated in the study. In the first, second and third trimesters, prevalence of anaemia was 7.6%, 19.7% and 19.3% respectively. Gestational age adjusted anaemia prevalence among pregnant women in this study population was 14.1% (95% CI 12.0-16.4%). Mean and median haemoglobin concentration of the study sample was 11.8g/dL (SD 1.02g/dl and IQR 11.2-12.5g/dl). Among anaemic pregnant women, average values for Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), and Mean Corpuscular Haemoglobin Concentration (MCHC) were, 82.9 fl (SD 11.5), 27.6 (SD-3.6) pg/cell and 32.9g/dl (SD 1.8) respectively. Sensitivity and specificity of haemoglobin colour scale method was 50% (95% CI 29.0-71.0%) and 76.3% (95% CI 66.9-83.7%) respectively. Sensitivity and specificity of conjunctival method in detecting anaemia during pregnancy was 18.8% (95% CI 11.9-28.4) and 69.3% (95% CI 58.2- 78.6%). Prevalence of anaemia in the district of Anuradhapura was less than 50% of the estimated prevalence for Sri Lanka. Both haemoglobin colour scale and conjunctival method were having low validity in detecting anaemia in pregnancy.

In our bloodstream, there are plenty of red blood cells (RBC), which function as an important oxygen carrier in our bodies. Each RBC consists of millions of haemoglobin (Hb), which is made up from globin and iron. If any deficiency/malfunction of any globin, it will lead to anaemia as indicated in low Hb level while iron deficiency anaemia (IDA) is anaemic due to the lacking of iron as indicated in low Hb and ferritin levels. IDA affects almost two billion people globally while anaemia without iron deficiency, such as thalassaemia, affects almost 4.5% in Malaysian population. These anaemic conditions have similar clinical symptoms like fatigue, dizziness, in which disturb their cognitive development and productivity in workplace. In areas without proper medical access, many anaemic individuals were misdiagnosed and treated with iron tablets because they were thought to have iron deficiency anaemia due to low Hb content. But, excess iron is toxic to the body. Misdiagnosis can be avoided by iron status assessment. We hereby review the currently available iron status parameters in laboratory and field study with the conclusion of demonstrating the importance of a need for iron reader, in the effort to reduce the prevalence of IDA globally.

Antibodies to actin in autoimmune haemolytic anaemia

Directory of Open Access Journals (Sweden)

Ritzmann Mathias

2010-03-01

Full Text Available Abstract Background In autoimmune haemolytic anaemia (AIHA, autoreactive antibodies directed against red blood cells are up-regulated, leading to erythrocyte death. Mycoplasma suis infections in pigs induce AIHA of both the warm and cold types. The aim of this study was to identify the target autoantigens of warm autoreactive IgG antibodies. Sera from experimentally M. suis-infected pigs were screened for autoreactivity. Results Actin-reactive antibodies were found in the sera of 95% of all animals tested. The reactivity was species-specific, i.e. reactivity with porcine actin was significantly higher than with rabbit actin. Sera of animals previously immunised with the M. suis adhesion protein MSG1 showed reactivity with actin prior to infection with M. suis indicating that molecular mimicry is involved in the specific autoreactive mechanism. A potentially cross-reactive epitope was detected. Conclusions This is the first report of autoreactive anti-actin antibodies involved in the pathogenesis of autoimmune haemolytic anaemia.

Xie, Haiwei; Zhang, Yan

2018-03-01

The relationship between dynamic infrared (IR) thermal images and blood perfusion rate of the tongues of anaemia patients was investigated. Blood perfusion rates at multiple locations on the tongues of 62 anaemia patients and 70 control subjects were measured. For both groups of subjects, dynamic IR thermal images were also recorded within 16 s after the mouth opened. The results showed that the blood perfusion rates at different sites (apex, middle, left side and right side) on the tongues in anaemia patients (3.49, 3.71, 3.85 and 3.77 kg/s m-3) were significantly lower than those at the corresponding sites in control subjects (4.45, 4.66, 4.81 and 4.70 kg/s m-3). After the mouth opened, the tongue temperature decreased more rapidly in anaemia patients than in control subjects. To analyse the heat transfer mechanism, a transient heat transfer model of the tongue was developed. The tongue temperatures in anaemia patients and control subjects were calculated using this model and compared to the tongue temperatures measured by the IR thermal imager. The relationship between the tongue surface temperature and the tongue blood perfusion rate was analysed. The simulation results indicated that the low blood perfusion rate and the correlated changes in anaemia patients can cause faster temperature decreases of the tongue surface.

Anaemia is common during pregnancy, and prenatal Fe supplementation is the standard of care. However, the persistence of anaemia despite Fe supplementation, particularly in HIV infection, suggests that its aetiology may be more complex and warrants further investigation. The present study was conducted to examine predictors of incident haematological outcomes in HIV-infected pregnant women in Tanzania. Prospective cohort study. Cox proportional hazards and binomial regression models were used to identify predictors of incident haematological outcomes: anaemia (Hb anaemia (Hb anaemia and hypochromic microcytosis during follow-up. Higher baseline erythrocyte sedimentation rate and CD8 T-cell concentrations, and lower Hb concentrations and CD4 T-cell counts, were independent predictors of incident anaemia and Fe deficiency. Low baseline vitamin D (anaemia and hypochromic microcytosis, respectively, during the follow-up period. Parasitic infections, vitamin D insufficiency, low CD4 T-cell count and high erythrocyte sedimentation rate were the main predictors of anaemia and Fe deficiency in pregnancy and the postpartum period in this population. A comprehensive approach to prevent and manage anaemia, including micronutrient supplementation and infectious disease control, is warranted in HIV-infected women in resource-limited settings - particularly during the pre- and postpartum periods.

The impact of renal insufficiency and anaemia on survival in patients with cardiovascular disease: a cohort study.

LENUS (Irish Health Repository)

Anderson, Jocelyn

2009-01-01

BACKGROUND: The simultaneous occurrence of cardiovascular disease (CVD), kidney disease, and anaemia is associated with increased morbidity and mortality. In the community setting, little data exists about the risk associated with milder levels of anaemia when it is present concurrently with CVD and chronic kidney disease (CKD). The aim of this study was to establish the prevalence of CKD and anaemia in patients with CVD in the community and to examine whether the presence of anaemia was associated with increased morbidity and mortality. METHODS: This study was designed as a retrospective cohort study and involved a random sample of 35 general practices in the West of Ireland. A practice-based sample of 1,609 patients with established cardiovascular disease was generated in 2000\\/2001 and followed for five years. The primary endpoint was death from any cause. Statistical analysis involved using one-way ANOVA and Chi-squared tests for baseline data and Cox proportional-hazards models for mortality data. RESULTS: Of the study sample of 617 patients with blood results, 33% (n = 203) had CKD while 6% (n = 37) had CKD and anaemia. The estimated risk of death from any cause, when compared to patients with cardiovascular disease only, was almost double (HR = 1.98, 95% CI 0.99 to 3.98) for patients with both CVD and CKD and was over 4 times greater (HR = 4.33, 95% CI 1.76 to 10.68) for patients with CVD, CKD and anaemia. CONCLUSION: In patients with cardiovascular disease in the community, chronic kidney disease and anaemia occur commonly. The presence of chronic kidney disease carries an increased mortality risk which increases in an additive way with the addition of anaemia. These results suggest that early primary care diagnosis and management of this high risk group may be worthwhile.

Risk of maternal mortality in women with severe anaemia during pregnancy and post partum: a multilevel analysis

Directory of Open Access Journals (Sweden)

Jahnavi Daru, MBBS

2018-05-01

Full Text Available Summary: Background: Anaemia affects as many as half of all pregnant women in low-income and middle-income countries, but the burden of disease and associated maternal mortality are not robustly quantified. We aimed to assess the association between severe anaemia and maternal death with data from the WHO Multicountry Survey on maternal and newborn health. Methods: We used multilevel and propensity score regression analyses to establish the relation between severe anaemia and maternal death in 359 health facilities in 29 countries across Latin America, Africa, the Western Pacific, eastern Mediterranean, and southeast Asia. Severe anaemia was defined as antenatal or postnatal haemoglobin concentrations of less than 70 g/L in a blood sample obtained before death. Maternal death was defined as death any time after admission until the seventh day post partum or discharge. In regression analyses, we adjusted for post-partum haemorrhage, general anaesthesia, admission to intensive care, sepsis, pre-eclampsia or eclampsia, thrombocytopenia, shock, massive transfusion, severe oliguria, failure to form clots, and severe acidosis as confounding variables. These variables were used to develop the propensity score. Findings: 312 281 women admitted in labour or with ectopic pregnancies were included in the adjusted multilevel logistic analysis, and 12 470 were included in the propensity score regression analysis. The adjusted odds ratio for maternal death in women with severe anaemia compared with those without severe anaemia was 2·36 (95% CI 1·60–3·48. In the propensity score analysis, severe anaemia was also associated with maternal death (adjusted odds ratio 1·86 [95% CI 1·39–2·49]. Interpretation: Prevention and treatment of anaemia during pregnancy and post partum should remain a global public health and research priority. Funding: Barts and the London Charity.

Full Text Available BACKGROUND India is one of the countries with very high prevalence of anaemia in the world. In India, almost 59% of pregnant women are anaemic and it accounts for 20-40% of total maternal deaths. Anaemia in pregnancy is one of the major risks and associated with abortions, premature births, postpartum haemorrhage and low birth weight. In view of the above, the present study was carried out to find out the prevalence of anaemia amongst pregnant women and sociodemographic factors associated with anaemia in pregnancy. MATERIALS AND METHODS A community-based cross-sectional study was carried out among 200 pregnant women with gestational period 12-20 weeks attending the antenatal sessions in 4 tea garden areas under Dholai BPHC, Cachar District, for 6 months from April 2016 to September 2016. Data were presented in proportion, mean and standard deviation. Association was seen by using Chi-square test and Fischer’s exact test. RESULTS Among 200 pregnant women, majority (38.5% were in 20-24 years of age, 98% Hindu by religion and 56% from class IV socioeconomic class. Regarding the educational status, 34.5% were educated up to primary school, while 33.5% were illiterate. Majority, i.e. 45.5% and 31.5% were having parity 0 and 1, respectively. Prevalence of anaemia in the present study was found to be 81% and among which 77.2% were moderately anaemic. The study showed significant association of anaemia among pregnant women with lower socioeconomic status and high parity. CONCLUSION In the present study, there is high prevalence (81% of anaemia among pregnant women. The study also noted that lower socioeconomic status and high parity had a significant role in anaemia during pregnancy. So, there is a need to intensify IEC activities to promote early antenatal care, increased compliance of intake of iron and folic acid tablets, dietary modification and utilisation of family planning services among pregnant women of this region.

Sorbi, Flavia; Mecacci, Federico; Di Filippo, Alessandro; Fambrini, Massimiliano

2017-02-03

Fanconi anaemia is a rare inherited disease characterized by congenital abnormalities, progressive bone marrow failure and predisposition to malignancy. Successful pregnancies in transplanted patients have been reported. In this paper we will describe the pregnancy of a patient with Fanconi anaemia without transplantation. A 34-year-old nulliparous woman with Fanconi anaemia was referred to our institution. Pregnancy was complicated by progressive pancytopenia and two severe infections. C-section was performed at 36 weeks. Both infant and mother are well. Successful pregnancy in a Fanconi anaemia patient with bone marrow failure is possible. The mode of delivery in patients with bone marrow failure should be determined by obstetric indications. The case highlights the safe outcome of the pregnancy with strict clinical and laboratory control by a multidisciplinary team.

Parasitic infections are of public health concern globally, particular among at risk groups such as pregnant women in developing countries. The presence of these parasites during pregnancy potentiate adverse effects to both the mother and the unborn baby. This study sought to establish the prevalence of some parasitic agents among antenatal attendees in the Dangme East District of Ghana. A cross-sectional prospective study was conduct between April and July, 2012. Venous blood specimens were collected from each participant for haemoglobin estimation and malaria microscopy. In addition participants' early morning mid-stream urine and stool specimens were analyzed microscopically for parasitic agents. A total of 375 pregnant women were involved in the study, of which anaemia was present in 66.4% (249/375). However, parasitic infections associated anaemia prevalence was 49.6% (186/375). In all, 186 cases of parasitic infections were observed; 171 (44.0%) were single isolated infections while 15 (4.0%) were co-infections. Plasmodium species were significantly associated with anaemia (13.3%, χ 2  = 23.290, p anaemia in pregnancy. Except where co-infections exist (3.7%, χ 2  = 11.267, p = 0.001), the rest of the single infections were insignificantly associated with anaemia. Collectively, intestinal helminthes were predominantly significant with anaemia in pregnancy (p = 0.001, χ 2  = 107.800). The study revealed relatively high prevalence of parasitic infections among the study population, suggesting that about three-quarters of the anaemic mothers are either single or co-infected with parasitic agents.

Anaemia in pregnancy still causes significant maternal morbidity and mortality in the developing countries including Nigeria. The burden and underlying factors are varied even within countries. We studied the prevalence of anaemia at booking and underlying factors in a teaching hospital in northern Nigeria. Using the capillary technique and blood film, the packed cell volume (PCV) and red cell morphology of 300 pregnant women was determined. Additional information was obtained on sociodemographic characteristics, obstetric and past medical history using an interviewer administered questionnaire. Of the 300 pregnant women studied, 51 (17%) [95% Confidence Interval (CI)=12.9%-21.7%] were anaemic. Specifically, 12.7% and 4.3% of the women had mild and moderate anaemia respectively. Blood film of 74.5%, 15.7% and 11.8% anaemic women showed normochromic normocytic, haemolytic and microcytic hypochromic pictures respectively. Low educational attainment [Adjusted Odds Ratio (AOR)=2.13], being single or divorced [AOR=2.02], high parity [AOR=2.06], late booking [AOR=2.71] and short intervals between pregnancies [AOR=2.37] were significant predictors of anaemia in pregnancy. The high prevalence of anaemia in pregnancy related to low educational and economic status especially among women with background obstetric risk factors calls for vigilance, sustained health education and chemoprophylaxis for pregnant women.

Twenty-nine patients with aplastic anemia and 11 patients with myelofibrosis were evaluated with indium-111 chloride bone-marrow imaging, ferrokinetics, and bone-marrow core biopsies. There was good correlation between the erythrocyte cellularity of the marrow and the In-111 bone-marrow scan grades in most patients. In some, the overall scan grade tended to underestimate the erythroid elements because the core biopsy had been taken from the area of the greatest radionuclide concentration on the scan. In patients with aplastic anemia, there was good correlation between the plasma iron clearance t1/2 and the scan grade. Less agreement was found in the comparison between the Fe-59 sacral and organ counts and the red-cell iron utilization. In patients with myelofibrosis, there was poor correlation between the surface counts over the sacrum and the red-cell iron utilization. Plasma iron clearances were abnormally short and were unrelated to the transferrin saturation levels. Eighteen patients were studied several times to evaluate their responses to steroid therapy. In all, there was good correlation between the bone-marrow imaging, the erythrocyte cellularity, ferrokinetics, and the patient's response to therapy. Indium-111 bone-marrow imaging is useful both in evaluating marrow erythroid activity and in following the response to therapy in patients with these diseases

There is limited longitudinal data from high-income countries on the sequelae of anaemia during pregnancy. The aim of this study is to examine whether anaemia of pregnancy is associated with adverse perinatal outcomes and with children's developmental vulnerability. We conducted a population-based study to link routinely collected government administrative data that involved all live births in the state of South Australia 1999-2005 (n = 124 061) and a subset for whom developmental data were collected during a national census of children attending their first year of school in 2009 (n = 13 654). Perinatal outcomes were recorded by midwives using a validated, standardised form. Development was recorded by schoolteachers using the Australian Early Development Index (AEDI). Children in the lowest 10% of AEDI scores are indicative of developmental vulnerability. There were 8764/124 061 (7.1%) cases of anaemia. After adjustment for a range of potentially confounding factors, anaemia of pregnancy was associated with a higher risk of fetal distress [incident rate ratio (IRR) 1.20 [95% CI 1.13, 1.27

Anaemia is an important complication of inflammatory bowel disease [IBD]. The aim of this study was to determine the prevalence of anaemia and the practice of anaemia screening during the first year following diagnosis, in a European prospective population-based inception cohort. Newly diagnosed IBD patients were included and followed prospectively for 1 year in 29 European and one Australian centre. Clinical data including demographics, medical therapy, surgery and blood samples were collected. Anaemia was defined according to the World Health Organization criteria. A total of 1871 patients (Crohn's disease [CD]: 686, 88%; ulcerative colitis [UC]: 1,021, 87%; IBD unclassified [IBDU] 164. 81%) were included in the study. The prevalence of anaemia was higher in CD than in UC patients and, overall, 49% of CD and 39% of UC patients experienced at least one instance of anaemia during the first 12 months after diagnosis. UC patients with more extensive disease and those from Eastern European countries, and CD patients with penetrating disease or colonic disease location, had higher risks of anaemia. CD and UC patients in need of none or only mild anti-inflammatory treatment had a lower risk of anaemia. In a significant proportion of patients, anaemia was not assessed until several months after diagnosis, and in almost half of all cases of anaemia a thorough work-up was not performed. Overall, 42% of patients had at least one instance of anaemia during the first year following diagnosis. Most patients were assessed for anaemia regularly; however, a full anaemia work-up was frequently neglected in this community setting.

The bone marrow failure syndromes (BMFS) are a heterogeneous group of rare blood disorders characterized by inadequate haematopoiesis, clonal evolution, and increased risk of leukaemia. Single nucleotide polymorphism arrays (SNP-A) have been proposed as a tool for surveillance of clonal evolution in BMFS. To better understand the natural history of BMFS and to assess the clinical utility of SNP-A in these disorders, we analysed 124 SNP-A from a comprehensively characterized cohort of 91 patients at our BMFS centre. SNP-A were correlated with medical histories, haematopathology, cytogenetic and molecular data. To assess clonal evolution, longitudinal analysis of SNP-A was performed in 25 patients. We found that acquired copy number-neutral loss of heterozygosity (CN-LOH) was significantly more frequent in acquired aplastic anaemia (aAA) than in other BMFS (odds ratio 12·2, P < 0·01). Homozygosity by descent was most common in congenital BMFS, frequently unmasking autosomal recessive mutations. Copy number variants (CNVs) were frequently polymorphic, and we identified CNVs enriched in neutropenia and aAA. Our results suggest that acquired CN-LOH is a general phenomenon in aAA that is probably mechanistically and prognostically distinct from typical CN-LOH of myeloid malignancies. Our analysis of clinical utility of SNP-A shows the highest yield of detecting new clonal haematopoiesis at diagnosis and at relapse. © 2013 John Wiley & Sons Ltd.

Full Text Available Background: Anaemia, though a common problem in Nigeria, has not been adequately studied amongst pregnant women in primary health care facilities. Objective: This study is aimed at determining the prevalence of anaemia and sociodemographic factors associated with anaemia in pregnancy in a primary health centre in Rivers State, Nigeria. Methodology: This is a cross-sectional study carried out in a primary health centre. Association between variables was analysed using the Chi-square test. Results: Two hundred and twenty-seven pregnant women whose ages ranged from 16 to 40 years with a mean age of 26.8 ± 4.3 years were recruited for the study. The haemoglobin concentration ranged from 6 g/dL – 15 g/dL with a mean of 10.10 ± 1.27g/dL. A total of 142 (62.6% participants were anaemic. Anaemia was observed to be least prevalent in women within the extremes of reproductive age (≤ 20 years and 36–40 years. There was no statistically significant association between age, educational level and marital status (p > 0.05. The association of anaemia with social class was statistically significant (p = 0.000. Severe anaemia was not a common finding amongst the patients but it was significantly associated with educational status (p = 0.02 and socio-economic status (p = 0.03. Conclusion: The prevalence of anaemia amongst the pregnant participants in the primary health centre was high. Out of all the socio-demographic characteristics, only socio-economic status was significantly associated with anaemia. It is recommended that the socio-economic status of women should be enhanced in line with the Millennium Development Goals to prevent anaemia and to enhance pregnancy outcomes.

Objective: To assess the prevalence of anaemia among rural pre-school (1-5-years children of Maharashtra. Methods: A community based cross-sectional study was carried by National Nutrition Monitoring Bureau (NNMB covering a total of 404 (Boys-243; Girls-161 pre-school children. Information of socio-demographic particulars was obtained and the finger prick blood samples were collected for the estimation of haemoglobin levels by cyanmethmoglobin method. Results: The result shows that 59.2 % (CI: 54.4-64.0 of the rural pre-school children of Maharashtra were anaemic, and the prevalence was significantly (p40% among rural pre-school children of Maharashtra. Therefore, appropriate intervention measures such as supplementary iron & folic acid, periodic deworming and health & nutrition education should be strengthened. The community needs to be encouraged to diversify their diets by consuming iron rich foods.

Several strategies are used in the care of pregnant women accessing antenatal care in primary health centres in Nigeria, with the aim of reducing the burden of malaria and anaemia. The objective of the study was to appraise the prevalence of malaria parasitaemia and anaemia in pregnant women attending antenatal clinics in rural communities of Southeastern Nigeria where malaria preventive strategies are in place. We undertook a cross-sectional study of 300 pregnant women receiving antenatal care in randomly selected primary health centres in the Nkanu West local government area (LGA), Enugu state, Nigeria from August to September 2010. The prevalence of malaria parasitaemia was 92.0% (276/300) (mild in 86.7% [260/300] and moderate in 15.3% [16/300]). The prevalence of anaemia was 49.3% (148/300) (mild in 29.3% [88/300] and moderate in 20% [60/300]). There were no severe cases of malaria parasitaemia or anaemia. The educational status and occupation of participants were significantly associated with the occurrence of peripheral parasitaemia and anaemia respectively (pprevalence of malaria and anaemia is very high in the Nkanu West LGA of Enugu State, Nigeria. Efforts to reduce the prevalence of malaria parasitaemia and anaemia in pregnancy should be intensified in rural settings of Enugu state and Nigeria as a whole. © The Author 2014.

This study estimated the prevalence of anaemia and associated factors in a probability sample of 993 chil- dren aged 6-59 months in Cape Verde, West Africa. Odds ratio (OR) and 95% confidence interval (95% CI) were estimated from a hierarchical model for multiple analysis to assess the association between anaemia and explanatory variables. The prevalence of anaemia was 51.8% (95% CI 47.7-55.8). Children who resided within poor household conditions (OR 1.99; 95% CI 1.06-3.71) were below 24 months of age (OR 3.23; 95% CI 2.03-5.15) and recently experienced diarrhoea (OR 1.58; 95% CI 0.99-2.50) were at high risk of anaemia. Anaemia should be considered a serious public-health concern in Cape Verde, mainly for chil- dren below 24 months. Further, special consideration should be given to children who have experienced recent diarrhoea and belong to families residing in poor household conditions.

The signal intensity of hematopoietic regions in the marrow of aplastic anemia were investigated on opposed phase T1-weighted images (op-T1WI) with a 0.5-Tesla MR unit. Hematopoietic regions were classified into two groups: low intensity hematopoietic areas (LH) isointense to normal marrow and high intensity hematopoietic regions (HH) with higher intensity than normal marrow on op-T1WI. The signal intensity of LH was significantly lower than that of HH on STIR. LH converted into HH with improvement of laboratory data after therapy, whereas HH decreased with impairment of data. HH were hyperintense to cerebrospinal fluid on op-T1WI. These results indicated that the signal intensity of hematopoietic regions on op-T1WI reflected the cellularity in these regions and that aplastic anemia included hypercellular regions relative to normal marrow.

Predicting the response to immunosuppressive therapy could provide useful information to help the clinician define treatment strategies for patients with aplastic anemia. In our current study, we evaluated the relationship between telomere length of lymphocytes at diagnosis and the response to immunosuppressive therapy in 64 children with aplastic anemia, using flow fluorescence in situ hybridization. Median age of patients was ten years (range 1.5–16.2 years). Severity of the disease was classified as very severe in 23, severe in 21, and moderate in 20 patients. All patients were enrolled in multicenter studies using antithymocyte globulin and cyclosporine. The response rate to immunosuppressive therapy at six months was 52% (33 of 64). The probability of 5-year failure-free survival and overall survival were 56% (95% confidence interval (CI): 41–69%) and 97% (95%CI: 87–99%), respectively. Median telomere length in responders was −0.4 standard deviation (SD) (−2.7 to +3.0 SD) and −1.5 SD (−4.0 to +1.6 (SD)) in non-responders (Paplastic anemia. PMID:24816243

Anaemia is a public health problem affecting over 1.62 billion people globally. It affects all age groups of people and is particularly more prevalent in pregnant women. Africa carries a high burden of anaemia; in Uganda 24 % of women of child bearing age have anaemia. Pregnant women living in poverty are at greater risk of developing iron deficiency anaemia. The objective of this study was to determine the prevalence of anaemia and the associated risk factors in pregnant women attending antenatal care at Gulu and Hoima Regional Hospitals in Northern and Western Uganda respectively. We conducted a cross sectional study in Gulu and Hoima Regional Hospitals from July to October 2012. Our study participants were pregnant women attending antenatal care. Socio-demographic data were collected using structured questionnaires and blood samples were collected for haemoglobin estimation. Haemoglobin concentration was determined using an automated analyzer closed mode of blood sampling. Data were analysed using Stata version 12. Odds ratio was used as a measure of association, with 95% confidence interval; and independent risk factors for anaemia were investigated using logistic regression analyses. Ethical approval was obtained from Gulu University Research Ethics Committee and written informed consent was obtained from each study participant. The overall prevalence of anaemia was 22.1%; higher in Gulu (32.9%) than in Hoima (12.1%), p prevalence of mild anaemia was 23%, moderate anaemia was 9%, and severe anaemia was 0.8%, while in Hoima, the prevalence of mild anaemia was 9%, moderate anaemia was 2.5%, and severe anaemia was 0.5%. Independent risk factors for anaemia were: being a housewife [Adjusted Odds Ratio (AOR) = 1.7, 95% CI: 1.05-2.68]; and being a resident in Gulu (AOR = 3.6, 95% CI: 2.41-5.58). The prevalence of anaemia in pregnant women in Gulu is higher than in Hoima. Amongst pregnancy women, being a housewife is an independent risk factor for anaemia

Pernicious anaemia and Campylobacter like organisms; is the gastric antrum resistant to colonisation?

Gastric biopsies from 86 patients with pernicious anaemia were examined for Campylobacter like organisms with particular attention to those showing an antral gastritis in addition to the usual pattern of body gastritis. All the patients had chronic atrophic gastritis in the body but Campylobacter like organisms were found at this site in only three patients. Thus the Type A pattern of gastritis (autoimmune) seen in patients with pernicious anaemia is only rarely associated with Campylobacter ...

Anaemia is the major cause of morbidity and mortality in paediatric age with much aetiology. The magnitude of childhood anaemia has been inadequately studied at Muhimbili National Hospital (MNH). The study was aimed at determining the frequency of anaemia and associated infections in patients admitted in general paediatric wards at MNH in Dar es Salaam. This was a descriptive cross-sectional study. This was conducted at MNH in general paediatric wards from 20th August, 2009 to 15th December, 2009. Patients, aged 1-84 months, consecutively admitted were recruited in the study. After informed verbal consent from the guardian or parent was obtained, information on demographic and clinical characteristics was collected from the parent or guardian. Physical examination and laboratory tests on blood ; stool samples for hookworm screening; blood slides for malaria parasites; Human Immunodeficiency Virus (HIV) screening; and blood peripheral smears were done on all subjects. Additional information was taken from medical files. Data management: The prevalence of anemia was determined as a percentage of all paediatric patients recruited during the time of data collection. All information was recorded using questionnaires and analysis was done using SPSS version 13.0. A p value of 1.0, p > 0.05). Anaemia in paediatric patients admitted at MNH is a disease of high public health importance in Dar es Salaam and may well carry a high burden in the rest of the country. Other risk factors of anaemia should be investigated with a goal of reducing the burden of anaemia.

Full Text Available Background: Anaemia, though a common problem in Nigeria, has not been adequatelystudied amongst pregnant women in primary health care facilities.Objective: This study is aimed at determining the prevalence of anaemia and sociodemographicfactors associated with anaemia in pregnancy in a primary health centre inRivers State, Nigeria.Methodology: This is a cross-sectional study carried out in a primary health centre. Associationbetween variables was analysed using the Chi-square test.Results: Two hundred and twenty-seven pregnant women whose ages ranged from 16 to40 years with a mean age of 26.8 ± 4.3 years were recruited for the study. The haemoglobinconcentration ranged from 6 g/dL – 15 g/dL with a mean of 10.10 ± 1.27g/dL. A total of142 (62.6% participants were anaemic. Anaemia was observed to be least prevalent inwomen within the extremes of reproductive age (≤ 20 years and 36–40 years. There was nostatistically significant association between age, educational level and marital status (p > 0.05.The association of anaemia with social class was statistically significant (p = 0.000. Severeanaemia was not a common finding amongst the patients but it was significantly associatedwith educational status (p = 0.02 and socio-economic status (p = 0.03.Conclusion: The prevalence of anaemia amongst the pregnant participants in the primaryhealth centre was high. Out of all the socio-demographic characteristics, only socio-economicstatus was significantly associated with anaemia. It is recommended that the socio-economicstatus of women should be enhanced in line with the Millennium Development Goals toprevent anaemia and to enhance pregnancy outcomes.

Acute post-partum anaemia can be associated with significant morbidity including a predisposition for postnatal depression. Lack of clear practice guidelines means a number of women are treated with multiple blood transfusions. Intravenous iron has the potential to limit the need for multiple blood transfusions but its role in the post-partum setting is unclear. IIBAPPA is a multi-centre randomised non-inferiority trial. Women with a primary post-partum haemorrhage (PPH) >1000 mL and resultant haemoglobin (Hb) 5.5-8.0 g/dL after resuscitation with ongoing symptomatic anaemia who are otherwise stable (no active bleeding) are eligible to participate. Patients with sepsis or conditions necessitating rapid Hb restoration are excluded. Eligible participants are randomised to receive a blood transfusion or a single dose of intravenous iron polymaltose calculated using the Ganzoni formula. Primary outcome measures include Hb, Ferritin and C-Reactive Protein levels on Day 7. Secondary outcomes evaluate (i) Hb, Ferritin and CRP levels on Day 14, 28, (ii) anaemia symptoms on Day 0, 7, 14 and 28 using structured health related quality of life questionnaires, (iii) treatment safety by assessing adverse reactions and infection endpoints and (iv) the quantitative impact of anaemia on breast feeding quality using a hospital designed questionnaire. If equivalence in Hb and ferritin levels, symptom scores and safety endpoints is demonstrated, intravenous iron may become the preferred treatment for women with acute post-partum anaemia to minimise transfusion reactions and costs.

We report a case of subcutaneous abscess caused by Nocardia farcinica in a 44-year-old man, who had been treated with systemic prednisolone and cyclosporin for aplastic anemia. He had been affected by aplastic anemia for 8 years, and was previously treated with antithymocyte globulin. The effect was insufficient, and platelet and erythrocyte transfusion was required. Bone marrow transplantation was not adopted due to a psychological problem. He had also been treated with prednisolone and cyclosporin for 3 years. Without apparent cause, swelling and pain of left upper extremity developed in April, 2008. There was no abnormality in cutaneous macroscopic findings, such as a wound or a sting. He was administered antibiotics, but they were ineffective and effusion were excreted into the skin. After hospitalization, he was treated by incision and drainage and antibiotics were started. The pathogen was identified as Nocardia farcinica by its biochemical characters. There was no dissemination to other organs like lung or brain and he recovered completely with a treatment of antibiotics for 1 year. We studied the epidemiological and clinical characteristics of Nocardia infections reported in Japan from 2000 to 2008 and identified 92 cases using the medical article search engine Ichushi-Web (Japan Medical Abstract Society). The results indicate that the most important risk factor in systemic nocardiosis ia an immunosuppressive agent such as prednisolone, cyclosporine, or azathioprine. We believe that we should take the possibility of Nocardia infection into consideration in a compromised host.

2018-02-01

Despite the demonstrated efficacy of hydroxyurea therapy, children with sickle cell anaemia in the UK are preferentially managed with supportive care or transfusion. Hydroxyurea is reserved for children with severe disease phenotype. This is in contrast to North America and other countries where hydroxyurea is widely used for children of all clinical phenotypes. The conservative UK practice may in part be due to concerns about toxicity, in particular marrow suppression with high doses, and growth in children. We monitored 37 paediatric patients with sickle cell anaemia who were treated with hydroxyurea at a single UK treatment centre. Therapy was well tolerated and mild transient cytopenias were the only toxicity observed. Comparative analysis of patients receiving ≥26 mg/kg/day versus hydroxyurea as a disease-modifying therapy, which we advocate for all children with sickle cell anaemia. © 2017 The Authors.

Objective: To assess quantitative and qualitative differences in water components between normal bone marrow and reactive hematopoietic marrow in aplastic anemia using magnetic resonance (MR) spectroscopy with variable echo times (TEs). Design: Water content, T2 value of the water component, and signal change in water related to TE were assessed in normal bone marrow and reactive hematopoietic bone marrow by a stimulated echo acquisition mode with TEs of 30, 45, 60, and 90 ms. Patients: Six patients with aplastic anemia (13-84 years) and seven normal volunteers (25-38 years) were examined. Results and conclusion: Reactive hematopoietic marrow showed significantly higher water content than normal bone marrow. The T2 value of water components tended to be longer in reactive hematopoietic marrow. Water signal ratio related to TE was significantly higher in reactive hematopoietic marrow. These results suggest a quantitative and qualitative difference in water components between normal and reactive hematopoietic bone marrow. (orig.)

The potential of enhanced chromatid damage, observed after X-irradiation of G{sub 2} phase, has been used to detect individuals genetically predisposed to cancer, utilising fibroblasts/lymphocytes from these patients as well as fibroblasts derived from human tumours. Fibroblasts and/or lymphocyte samples of two autosomal recessive syndromes (xeroderma pigmentosum (XP), Fanconi`s anaemia (FA)) and one congenital or acquired disorder, aplastic anaemia (AA), were employed for the G{sub 2} radiosensitivity assay. In addition, we have estimated the frequencies of spontaneously occurring chromosomal aberrations as well as G{sub 2} radiosensitivity of eight samples of fibroblasts/fibroblast-like cells (two normal, two colorectal carcinoma, two Wilms` tumour, one retinoblastoma and one polyposis coli), and three samples of lymphocytes (two normal and one from a lymphoma patient). The results obtained indicate that there were no differences between fibroblast cells derived from patients or tumours, except FA patients, in the frequency of spontaneously occurring chromosomal aberrations when compared to normal cells. Following X-irradiation we did not observe any significantly increased G{sub 2} radiosensitivity in FA and XP cells. Lymphocytes from AA and lymphoma patients, and all tumour cell lines except retinoblastoma, responded with increased frequencies of aberrations following G{sub 2} X-irradiation in comparison to cells derived from normal individuals. In our hands, the G{sub 2} sensitivity assay could not always discriminate cells from cancer-prone individuals from those of controls.

Laboratory diagnosis of the rare anaemias: external quality assessment benefits patient care

Directory of Open Access Journals (Sweden)

Barbara De La Salle

2013-03-01

Full Text Available Since its introduction in the 1960s, external quality assessment has developed to become an essential component of the quality management system of the diagnostic laboratory. External quality assessment provides a long term, retrospective view of laboratory performance, demonstrating the competence of the laboratory to others. The ENERCA project (the European Network for Rare and Congenital Anaemias has established a list of core laboratory tests that are used in the diagnosis of rare and congenital anaemias, which has been used as the basis for questionnaires to laboratories, to establish the use and quality assurance of diagnostic testing in the congenital and rare anaemias, and to European EQA providers for services in this key area. In general, the provision of EQA for rare and congenital anaemias is widely variable with little provision for the very rare disorders. For the more common congenital anaemias, such as the haemoglobinopathies and thalassaemias, provision is better but there is variation in aspects of the scheme design, especially the frequency of distribution. Where laboratories did not take part in EQA for individual tests, or there was no EQA available, a desire to participate was expressed in 66% (102/154 of cases. The provision of external quality assessment (EQA services for rare disorders is a challenge. For many of these conditions, the number of patients in any one member state is very small with only a few laboratories providing diagnostic testing. In these cases, the development of pan-European or cross-border EQA may be the only means by which standardisation of methods and results can be achieved. An EQA survey of 243 laboratories for performance in Hb A2 quantification showed encouraging results in that there was a clear differentiation in the results from a beta Thalassaemia carrier and an individual with no evidence of Thalassaemia; however, a bias was observed between different methods of measurement.

With growing use of nivolumab, rare but serious side effects have surfaced in some patients. We present a case of autoimmune haemolytic anaemia that developed after 39 cycles of nivolumab. A 78-year-old man with metastatic lung adenocarcinoma, refractory to multiple lines of chemotherapy was switched to nivolumab. After around 2 years of stable course on nivolumab, he developed transfusion-dependent anaemia with haemoglobin of 8.6 g/dL. Nivolumab was held immediately. Bone marrow biopsy findings were inconclusive of myelodysplastic syndrome. Further testing was suggestive of haemolysis with haptoglobin <10 mg/dL, elevated reticulocyte count and identification of immunoglobulin G antibody. Haemoglobin improved significantly with initiation of 1 mg/kg prednisone in addition to rituximab weekly × four doses. The development of transfusion-dependent anaemia with the exposure to cytotoxic chemotherapy usually raises the question for myelodysplastic syndrome. In contradiction, our patient was diagnosed to have a haematological autoimmune complication related to immunotherapy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Despite the trend of increasing prevalence of childhood anaemia in Armenia, no studies exploring its risk factors have been conducted in the country. The present study aimed to investigate the prevalence and determinants of childhood anaemia in rural Armenia. Blood Hb level was measured among a representative sample of children using the HemoCue Hb201+ analyser. The revealed cases with anaemia were compared with randomly selected non-anaemic controls. Mothers of cases and controls were interviewed. Logistic and linear regression models were fitted to identify the risk factors of anaemia and low Hb level, respectively. Talin communities, Aragatsotn Province, Armenia. Children under 5 years of age in Talin region. Of the 729 studied children, 32·4% were anaemic with 14·7% having moderate/severe anaemia. Infants were the most affected group with 51·1% being anaemic before 6 months and 67·9% at 6-12 months of age. Fitted regression models identified the following predictors of anaemia: younger age, male gender, shorter birth length, anaemia during pregnancy, lower meal frequency per day, lack of meat in the diet, using dung cakes for heating and living in a community that received an incomplete set of nutrition interventions. The study identified several modifiable risk factors that could be targeted to reduce childhood anaemia in rural Armenia and, possibly, in rural areas in other low-/middle-income countries. The suggested interventions include prevention and treatment of anaemia during pregnancy, provision of adequate complementary feeding to children with inclusion of meat in their daily diet and reduction of their exposure to biomass fuel smoke.

Anaemia in pregnancy is an important health issue resulting in high maternal morbidity and mortality. The purpose of the current study was to identify factors associated with anaemia among pregnant women receiving antenatal care at the Sunyani Municipal Hospital in Ghana. A cross-sectional study involving pregnant women seeking antenatal care at the Sunyani Municipal Hospital was conducted between May and June, 2015. It involved the collection of data on socio demographic and obstetric variables, medical interventions and malaria infection, consumption of iron containing foods and supplements using a case record form and a structured questionnaire. Also, data on haemoglobin concentrations at first and current antenatal visit were collected. Bivariate and multivariate statistical analysis were done to determine factors associated with anaemia. Out of the 316 participants, 129 (40.8%) were found to be anaemic (Hb prevalence of anaemia was found to be similar to that of the first visit with 131 (41.5%) of them being anaemic [mean Hb: 11.24 g/dl, range 8.10-14.5 g/dl]. The haemoglobin levels however improved significantly during the most recent visit compared to the first with none of the women being severely anaemic (Hb prevalence of moderate anaemia reduced from 37.2% (CI 28.9-46.2) during the first visit to 19.1% (12.7-26.9) during the most recent visit, a reduction of 48.7%. Malaria infection, frequency at which one consumed fish/snails and gestational age at first ANC visit were the main factors found to be associated with anaemia among the pregnant women. Malaria infection, fish/snails intake and gestational age at first ANC visit were significantly associated with anaemia. Addressing these factors can reduce the incidence of anaemia in pregnancy.

Introduction. Different ferric and ferrous iron preparations can be used as oral iron supplements. Our aim was to compare the effects of oral ferric and ferrous iron therapies in women with iron deficiency anaemia. Methods. The present study included 104 women diagnosed with iron deficiency anaemia after evaluation. In the evaluations performed to detect the aetiology underlying the iron deficiency anaemia, it was found and treated. After the detection of the iron deficiency anaemia aetiology and treatment of the underlying aetiology, the ferric group consisted of 30 patients treated with oral ferric protein succinylate tablets (2 × 40 mg elemental iron/day), and the second group consisted of 34 patients treated with oral ferrous glycine sulphate tablets (2 × 40 mg elemental iron/day) for three months. In all patients, the following laboratory evaluations were performed before beginning treatment and after treatment. Results. The mean haemoglobin and haematocrit increases were 0.95 g/dL and 2.62% in the ferric group, while they were 2.25 g/dL and 5.91% in the ferrous group, respectively. A significant difference was found between the groups regarding the increase in haemoglobin and haematocrit values (P < 0.05). Conclusion. Data are submitted on the good tolerability, higher efficacy, and lower cost of the ferrous preparation used in our study. PMID:25006339

The severity of malarial anaemia in Plasmodium chabaudi infections of BALB/c mice is determined independently of the number of circulating parasites

Directory of Open Access Journals (Sweden)

Lamb Tracey J

2008-04-01

Full Text Available Abstract Background Severe malarial anaemia is a major complication of malaria infection and is multi-factorial resulting from loss of circulating red blood cells (RBCs from parasite replication, as well as immune-mediated mechanisms. An understanding of the causes of severe malarial anaemia is necessary to develop and implement new therapeutic strategies to tackle this syndrome of malaria infection. Methods Using analysis of variance, this work investigated whether parasite-destruction of RBCs always accounts for the severity of malarial anaemia during infections of the rodent malaria model Plasmodium chabaudi in mice of a BALB/c background. Differences in anaemia between two different clones of P. chabaudi were also examined. Results Circulating parasite numbers were not correlated with the severity of anaemia in either BALB/c mice or under more severe conditions of anaemia in BALB/c RAG2 deficient mice (lacking T and B cells. Mice infected with P. chabaudi clone CB suffered more severe anaemia than mice infected with clone AS, but this was not correlated with the number of parasites in the circulation. Instead, the peak percentage of parasitized RBCs was higher in CB-infected animals than in AS-infected animals, and was correlated with the severity of anaemia, suggesting that the availability of uninfected RBCs was impaired in CB-infected animals. Conclusion This work shows that parasite numbers are a more relevant measure of parasite levels in P. chabaudi infection than % parasitaemia, a measure that does not take anaemia into account. The lack of correlation between parasite numbers and the drop in circulating RBCs in this experimental model of malaria support a role for the host response in the impairment or destruction of uninfected RBC in P. chabaudi infections, and thus development of acute anaemia in this malaria model.

Anaemia affects as many as half of all pregnant women in low-income and middle-income countries, but the burden of disease and associated maternal mortality are not robustly quantified. We aimed to assess the association between severe anaemia and maternal death with data from the WHO Multicountry Survey on maternal and newborn health. We used multilevel and propensity score regression analyses to establish the relation between severe anaemia and maternal death in 359 health facilities in 29 countries across Latin America, Africa, the Western Pacific, eastern Mediterranean, and southeast Asia. Severe anaemia was defined as antenatal or postnatal haemoglobin concentrations of less than 70 g/L in a blood sample obtained before death. Maternal death was defined as death any time after admission until the seventh day post partum or discharge. In regression analyses, we adjusted for post-partum haemorrhage, general anaesthesia, admission to intensive care, sepsis, pre-eclampsia or eclampsia, thrombocytopenia, shock, massive transfusion, severe oliguria, failure to form clots, and severe acidosis as confounding variables. These variables were used to develop the propensity score. 312 281 women admitted in labour or with ectopic pregnancies were included in the adjusted multilevel logistic analysis, and 12 470 were included in the propensity score regression analysis. The adjusted odds ratio for maternal death in women with severe anaemia compared with those without severe anaemia was 2·36 (95% CI 1·60-3·48). In the propensity score analysis, severe anaemia was also associated with maternal death (adjusted odds ratio 1·86 [95% CI 1·39-2·49]). Prevention and treatment of anaemia during pregnancy and post partum should remain a global public health and research priority. Barts and the London Charity.

to explore anaemia-related perceptions and practices among pregnant women in Mumbai, India. descriptive qualitative study using in-depth interviews and focus group discussions. three government-run maternity hospitals in Mumbai, India. 31 pregnant women aged 18-33 years; three women completed higher secondary school; 28 were homemakers. respondents described anaemia as 'lack of blood in the body' because that was the term used by health providers; yet they did not seem worried about the consequence on their own health. Women perceived anaemia as 'normal during pregnancy' because their body had to simply share resources with the fetus and every female relative had suffered from it during pregnancy. Respondents did recognise weakness and dizziness as symptoms of anaemia. They attributed the cause to a poor diet, but did not know the specific link with iron-deficiency. They listed various negative effects of anaemia on the fetus, but very few stated ill-effects on the mother, and none stated maternal death as an outcome. Women saw their role primarily as child-bearers and prioritised newborn's health over their own. anaemia stands at the intersection of health, nutrition, culture and gender. Interventions in the country have to go beyond distributing or monitoring compliance with iron-folic acid (IFA) supplements. Health education programmes for women and household members have to highlight the seriousness of anaemia and address socio-cultural norms and gendered behaviours in families with respect to nutrition and health. There is an urgent need in maternal and child health programmes to emphasise the importance of the mother's own health. Anaemia interventions have the potential to become proxies for women's health and empowerment programmes. © 2013 Elsevier Ltd. All rights reserved.

Livestock ownership may influence anaemia through complex and possibly contradictory mechanisms. In this study, we aimed to determine the association of household livestock ownership with anaemia among women aged 15-49 years and children aged 6-59 months in Ghana and to examine the contribution of animal source foods (ASFs) to consumption patterns as a potential mechanism mediating this association. We analysed data on 4,441 women and 2,735 children from the 2014 Ghana Demographic and Health Survey and 16,772 households from the Ghana Living Standards Survey Round 6. Haemoglobin measurements were used to define anaemia (non-pregnant women: <120 g/L; children: <110 g/L). Child- and household-level ASF consumption data were collected from 24-hour food group intake and food consumption and expenditure surveys, respectively. In multiple logistic regression models, household livestock ownership was associated with anaemia among children (OR, 95% CI: 1.5 [1.1, 2.0]), but not women (1.0 [0.83, 1.2]). Household ownership of chickens was associated with higher odds of anaemia among children (1.6 [1.2, 2.2]), but ownership of other animal species was not associated with anaemia among women or children. In path analyses, we observed no evidence of mediation of the association of household livestock ownership with child anaemia by ASF consumption. Ownership of livestock likely has limited importance for consumption of ASFs among young children in Ghana and may in fact place children at an increased risk of anaemia. Further research is needed to elucidate if and how pathogen exposure associated with livestock rearing may underlie this increased risk of anaemia. © 2018 The Authors.

Studies in western healthcare settings suggest that preoperative anaemia is associated with poor outcomes after elective orthopaedic surgery. We investigated the prevalence of preoperative anaemia among patients with primary unilateral total knee arthroplasty (TKA) in Singapore and its association with length of hospital stay (LOS), perioperative blood transfusion and hospital readmission rates. Retrospective cohort study performed in a tertiary academic medical centre in Singapore, involving patients who underwent primary unilateral TKA between January 2013 and June 2014. Demographics, comorbidities, preoperative haemoglobin (Hb) level, LOS and 30-day readmission data were collected. Anaemia was classified according to WHO definition. Prolonged LOS was defined as more than 6 days, which corresponds to >75th centile LOS of the data. We analysed 2394 patients. The prevalence of anaemia was 23.7%. 403 patients (16.8%) had mild anaemia and 164 patients (6.8%) had moderate to severe anaemia. Overall mean LOS was 5.4±4.8 days. Based on multivariate logistic regression, preoperative anaemia significantly increased LOS (mild anaemia, adjusted OR (aOR) 1.71, p70 years were associated with prolonged LOS. Our 30-day related readmission rate was 1.7% (42) cases. Anaemia is common among patients undergoing elective TKA in Singapore and is independently associated with prolonged LOS and increased perioperative blood transfusion. We suggest measures to correct anaemia prior to surgery, including the use of non-gender-based Hb cut-off for establishing diagnosis. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

2008-09-01

Full Text Available Hookworm infection is among the major causes of anaemia in poor communities, but its importance in causing maternal anaemia is poorly understood, and this has hampered effective lobbying for the inclusion of anthelmintic treatment in maternal health packages. We sought to review existing evidence on the role of hookworm as a risk factor for anaemia among pregnant women. We also estimate the number of hookworm infections in pregnant women in sub-Saharan Africa (SSA.Structured searches using MEDLINE and EMBASE as well as manual searches of reference lists were conducted, and unpublished data were obtained by contacting authors. Papers were independently reviewed by two authors, and relevant data were extracted. We compared haemoglobin concentration (Hb according to intensity of hookworm infection and calculated standardised mean differences and 95% confidence intervals. To estimate the number of pregnant women, we used population surfaces and a spatial model of hookworm prevalence.One hundred and five reports were screened and 19 were eligible for inclusion: 13 cross-sectional studies, 2 randomised controlled trials, 2 non-randomised treatment trials and 2 observational studies. Comparing uninfected women and women lightly (1-1,999 eggs/gram [epg] infected with hookworm, the standardised mean difference (SMD was -0.24 (95% CI: -0.36 to -0.13. The SMD between women heavily (4000+ epg infected and those lightly infected was -0.57 (95% CI: -0.87 to -0.26. All identified intervention studies showed a benefit of deworming for maternal or child health, but since a variety of outcomes measures were employed, quantitative evaluation was not possible. We estimate that 37.7 million women of reproductive age in SSA are infected with hookworm in 2005 and that approximately 6.9 million pregnant women are infected.Evidence indicates that increasing hookworm infection intensity is associated with lower haemoglobin levels in pregnant women in poor countries

Maternal and perinatal morbidity and mortality remain major challenges in the delivery of safe maternity care worldwide. Anaemia in pregnancy is an important contributor to this dismal picture, especially where blood transfusion services are poorly developed. An early diagnosis and treatment of iron deficiency anaemia in pregnancy using the new generation dextran-free parenteral iron preparations can save lives and reduce morbidity in selected pregnancies. It is time to cast aside the fears associated with the use of the old parenteral iron preparations which were associated a high incidence of anaphylaxis, and embrace the use of new parenteral iron products which have better side effect profiles and can deliver total dose infusions without the need for test dosing. In selected women, the benefits of this treatment far outweigh any disadvantages.

Although substantiated by little evidence, concerns about zidovudine-related anaemia in pregnancy have influenced antiretroviral (ARV) regimen choice for preventing mother-to-child transmission of HIV-1, especially in settings where anaemia is common. Eligible HIV-infected pregnant women in Burkina Faso, Kenya and South Africa were followed from 28 weeks of pregnancy until 12-24 months after delivery (n = 1070). Women with a CD4 count of 200-500 cells/mm(3) and gestational age 28-36 weeks were randomly assigned to zidovudine-containing triple-ARV prophylaxis continued during breastfeeding up to 6-months, or to zidovudine during pregnancy plus single-dose nevirapine (sd-NVP) at labour. Additionally, two cohorts were established, women with CD4 counts: 500 cells/mm(3) received zidovudine during pregnancy plus sd-NVP at labour. Mild (haemoglobin 8.0-10.9 g/dl) and severe anaemia (haemoglobin anaemia occurred subsequently in 194 (18.1%) women, mostly in those with low baseline haemoglobin, lowest socio-economic category, advanced HIV disease, prolonged breastfeeding (≥ 6 months) and shorter ARV exposure. Severe anaemia incidence was similar in the randomized arms (equivalence P-value = 0.32). After 1-2 months of ARV's, severe anaemia was significantly reduced in all groups, though remained highest in the low CD4 cohort. Severe anaemia occurs at a similar rate in women receiving longer triple zidovudine-containing regimens or shorter prophylaxis. Pregnant women with pre-existing anaemia and advanced HIV disease require close monitoring. ISRCTN71468401.

Research on associated risk factors for intestinal parasitic infections and malnutrition in various geographic regions is needed for the development of appropriate control strategies. The aim of this study was to determine the risk factors associated with intestinal parasitic infections, anaemia, and malnutrition in school children, living in urban and rural areas of northern Ethiopia. Six hundred school children, aged 6-15 years, were randomly selected in a cross-sectional survey from 12 primary schools. Sociodemographic and anthropometric data were collected. Faecal samples were examined using direct, concentration, and the Kato-Katz methods. Urine specimens were analysed for Schistosoma haematobium ova. Haemoglobin was measured using a HemoCue spectrometer. The overall prevalence of intestinal parasitosis was 72% (95% confidence interval (CI): 66-76%). The prevalence of anaemia, stunting, and thinness were 11% (95% CI: 8-13%), 35% (95% CI: 31-38%), and 34% (95% CI: 30-38%), respectively. Poor personal hygiene habits were generally associated with anaemia and nutritional deficiency (low body mass index). Multivariate logistic regression models related Schistosoma mansoni infection with boys. Boys were also more likely to be malnourished. Hookworm infection was associated with anaemia and unhygienic finger nails. Access to clean water and latrines, with some hygiene and sanitation communication activities, could improve health of children in Ethiopia. The use of smartphone technology in demographic data collection proved to be successful. The potential advantage offered by this technology for parasitological field surveys merits further investigation.

Afghanistan has some of the worst maternal and infant mortality indicators in the world and malaria is a significant public health concern. Study objectives were to assess prevalence of malaria and anaemia, related knowledge and practices, and malaria prevention barriers among pregnant women in eastern Afghanistan. Three studies were conducted: (1) a clinical survey of maternal malaria, maternal anaemia, and neonatal birthweight in a rural district hospital delivery-ward; (2) a case-control study of malaria risk among reproductive-age women attending primary-level clinics; and (3) community surveys of malaria and anaemia prevalence, socioeconomic status, malaria knowledge and reported behaviour among pregnant women. Among 517 delivery-ward participants (1), one malaria case (prevalence 1.9/1000), 179 anaemia cases (prevalence 346/1000), and 59 low-birthweight deliveries (prevalence 107/1000) were detected. Anaemia was not associated with age, gravidity, intestinal parasite prevalence, or low-birthweight at delivery. Among 141 malaria cases and 1010 controls (2), no association was found between malaria infection and pregnancy (AOR 0.89; 95 % CI 0.57-1.39), parity (AOR 0.95; 95 % CI 0.85-1.05), age (AOR 1.02; 95 % CI 1.00-1.04), or anaemia (AOR 1.00; 95 % CI 0.65-1.54). Those reporting insecticide-treated net usage had 40 % reduced odds of malaria infection (AOR 0.60; 95 % CI 0.40-0.91). Among 530 community survey participants (3), malaria and anaemia prevalence were 3.9/1000 and 277/1000 respectively, with 34/1000 experiencing severe anaemia. Despite most women having no formal education, malaria knowledge was high. Most expressed reluctance to take malaria preventive medication during pregnancy, deeming it potentially unsafe. Given the low malaria risk and reported avoidance of medication during pregnancy, intermittent preventive treatment is hard to justify or implement. Preventive strategy should instead focus on long-lasting insecticidal nets for all pregnant

Fanconi anaemia is a heterogeneous genetic disease, where 12 complementation groups have been already described. Identifying the complementation group in patients with Fanconi anaemia constitutes a direct procedure to confirm the diagnosis of the disease and is required for the recruitment of these patients in gene therapy trials. To determine the subtype of Fanconi anaemia patients in Spain, a Mediterranean country with a relatively high population (23%) of Fanconi anaemia patients belonging to the gypsy race. Most patients could be subtyped by retroviral complementation approaches in peripheral blood T cells, although some mosaic patients were subtyped in cultured skin fibroblasts. Other approaches, mainly based on western blot analysis and generation of nuclear RAD51 and FANCJ foci, were required for the subtyping of a minor number of patients. From a total of 125 patients included in the Registry of Fanconi Anaemia, samples from 102 patients were available for subtyping analyses. In 89 cases the subtype could be determined and in 8 cases exclusions of common complementation groups were made. Compared with other international studies, a skewed distribution of complementation groups was observed in Spain, where 80% of the families belonged to the Fanconi anaemia group A (FA-A) complementation group. The high proportion of gypsy patients, all of them FA-A, and the absence of patients with FA-C account for this characteristic distribution of complementation groups.

Iron deficiency anaemia (IDA) is the most common nutritional deficiency in pregnancy. Prophylactic oral iron is recommended during pregnancy to meet the increased requirement. In India, women become pregnant with low baseline haemoglobin level resulting in high incidence of moderate to severe anaemia in pregnancy where oral iron therapy cannot meet the requirement. Pregnant women with moderate anaemia are to be treated with parentral iron therapy. This study was undertaken to evaluate the response and effect of intravenous iron sucrose complex (ISC) given to pregnant women with IDA. A prospective study was conducted (June 2009 to June 2011) in the department of Obstetrics & Gynecology, All India Institute of Medical Sciences, New Delhi. One hundred pregnant women with haemoglobin between 5-9 g% with diagnosed iron deficiency attending antenatal clinic were given intravenous iron sucrose complex in a dose of 200 mg twice weekly schedule after calculating the dose requirement. The mean haemoglobin raised from 7.63 ± 0.61 to 11.20 ± 0.73 g% (Panaemia. Intravenous iron sucrose can be used in hospital settings and tertiary urban hospitals where it can replace intramuscular therapy due to injection related side effects. Further, long-term comparative studies are required to recommend its use at peripheral level.

Full Text Available Anaemia is associated with adverse outcomes including early death in the first year of antiretroviral therapy (ART. This study reports on the factors associated with persistent anaemia among HIV-infected patients initiating ART in the Democratic Republic of Congo (DR Congo.We conducted a retrospective cohort study and analyzed data from patients receiving HIV care between January 2004 and December 2012 at two major hospitals in Goma, DR Congo. Haemoglobin concentrations of all patients on ART regimen were obtained prior to and within one year of ART initiation. A logistic regression model was used to identify the predictors of persistent anaemia after 12 months of ART.Of 756 patients, 69% of patients were anaemic (IC95%: 65.7-72.3 at baseline. After 12 months of follow up, there was a 1.2 g/dl average increase of haemoglobin concentration (P < 0.001 with differences depending on the therapeutic regimen. Patients who received zidovudine (AZT gained less than those who did not receive AZT (0.99 g/dl vs 1.33 g/dl; p< 0.001. Among 445 patient who had anaemia at the beginning, 33% (147/445 had the condition resolved. Among patients with anaemia at ART initiation, those who did not receive cotrimoxazole prophylaxis before starting ART(AOR 3.89; 95% CI 2.09-7.25; P < 0.001 and a AZT initial regimen (AOR 2.19; 95% CI 1.36-3.52; P < 0.001 were significantly at risk of persistent anaemia.More than two thirds of patients had anaemia at baseline. The AZT-containing regimen and absence of cotrimoxazole prophylaxis before starting ART were associated with persistent anaemia 12 months, after initiation of treatment. Considering the large proportion of patients with persistence of anaemia at 12 months, we suggest that it is necessary to conduct a large study to assess anaemia among HIV-infected patients in Goma.

Aplastic anemia is a bone marrow failure syndrome with high mortality affecting children and young adults. Although current treatment guidelines recommend hematopoietic stem cell transplant (HCT) for patients with matched sibling donors, outcomes with alternate donor options have been improving. We analyzed a validated multiinstitutional pediatric cohort using one of the largest pediatric and young adult database, the Pediatric Health Information System, for patients diagnosed with aplastic anemia (AA) from 2006 to 2015. Outcomes with upfront and salvage transplants were analyzed along with healthcare utilization. Among 2,169 patients in the study period, almost 20% underwent HCT, while others received immunosuppressive therapy. In a multivariate model, there was no significant difference in mortality with upfront or salvage transplants (odds ratio [OR] 1.24, 95% confidence interval [CI] 0.6-2.58, P = 0.567), while every platelet transfusion was associated with higher mortality (OR 1.37, 95% CI 1.12-1.67, P = 0.002). Healthcare utilization was significantly higher in salvage transplants requiring frequent hospitalization and transfusion requirements. Treatment mortality and graft failure rates were significantly reduced in the salvage transplant group in recent years (2011-2015 as compared to 2006-2010). As outcomes with HCT continue to improve in severe AA, transplant with good alternate donors should be considered upfront in children and young adults. © 2017 Wiley Periodicals, Inc.

The prevalence of anaemia during pregnancy is estimated to be 35-75% in sub-Saharan Africa and is associated with an increased risk of maternal mortality. We evaluated the frequency and factors associated with anaemia in HIV-infected women undergoing antiretroviral (ARV) therapy for prevention of mother-to-child transmission (PMTCT) enrolled in The Kisumu Breastfeeding Study 2003-2009. Maternal haematological parameters were monitored from 32 to 34 weeks of gestation to 2 years post-delivery among 522 enrolled women. Clinical and laboratory assessments for causes of anaemia were performed, and appropriate management was initiated. Anaemia was graded using the National Institutes of Health Division of AIDS 1994 Adult Toxicity Tables. Data were analysed using SAS software, v 9.2. The Wilcoxon two-sample rank test was used to compare groups. A logistic regression model was fitted to describe the trend in anaemia over time. At enrolment, the prevalence of any grade anaemia (Hb anaemia (Hb anaemia events occurred around delivery (48.8%; n = 20). Anaemia (Hb ≥ 7 and anaemia at delivery (OR 5.87; 95% CI: 4.48, 7.68, P anaemia coincided with clinical malaria (24.4%; n = 10) and helminth (7.3%; n = 3) infections. Resolution of anaemia among most participants during study follow-up was likely related to receipt of ARV therapy. Efforts should be geared towards addressing common causes of anaemia in HIV-infected pregnant women, prioritising initiation of ARV therapy and management of peripartum blood loss. © 2016 John Wiley & Sons Ltd.

Full Text Available We studied the prevalence of iron-deficiency anaemia in women of reproductive age, between 15 to 49, with a mean age of 31-56±1.34 years, attending Mirzakoochak khan Hospital OB. GYN. Center for routine gynecological and obstetrical examination. We compa'tred mean values for the serum tests and haematological data and investigated etiological factors such as age, marital status, education, spouse's education, occupation, spouse's occuption, number of days of menstrual bleeding, severity of menstrual bleeding, pregnancy status, number of pregnancies, number of deliveries, intervals between successive pregnancies, ami smoking status, as probable causes of iron-deficiency anaemia in women. Moreover the relevance between occurance of iron-deficiency anaemia or ferritin serum level to etiological factors and diagnostic laboratory tests arc analyzed. A serum diagnosis of iron-deficiency was accepted on the basis of one or more of the following test results: serum ferritin levels below 12 figf with or without transferrin saturation below 16%. For the purpose of this study anaemia was difind as haemoglobin (Hb below 12 gdf . Women have been classified into two groups of anaemic Vs normal according to the diagnosis. Prevalence of anaemia among 41 subjects with complete laboratory results was 36.58%. Moreover, the probability of occurance of iron-deficiency anaemia, in general population was fount! to be 33.3%. As a result a significant relationship was observed between occurance of iron-deficiency anaemia and diagnostic laboratory tests including serum ferritin, serum iron, total iron-binding capacity (TIBC, transferring saturation (%, Hb, haematocrit (Hct, mean corpuscular haemoglobin (MCH, mean corpuscular volume (MCV, mean corpuscular haemoglobin concentration (MCHC, and etiological factors such as number of days of menstrual bleeding, severity of menstrual bleeding. Same relationship was observed between serum ferritin levels and

Acquired aplastic anemia (aAA) is an acquired deficiency of early hematopoietic cells, characterized by inadequate blood production, and a predisposition to myelodysplastic syndrome (MDS) and leukemia. Although its exact pathogenesis is unknown, aAA is thought to be driven by human leukocyte antigen (HLA)–restricted T cell immunity, with earlier studies favoring HLA class II-mediated pathways. Using whole-exome sequencing (WES), we recently identified 2 patients with aAA with somatic mutations in HLA class I genes. We hypothesized that HLA class I mutations are pathognomonic for autoimmunity in aAA, but were previously underappreciated because the major histocompatibility complex (MHC) region is notoriously difficult to analyze by WES. Using a combination of targeted deep sequencing of HLA class I genes and single nucleotide polymorphism array (SNP-A) genotyping, we screened 66 patients with aAA for somatic HLA class I loss. We found somatic HLA loss in 11 patients (17%), with 13 loss-of-function mutations in HLA-A*33:03, HLA-A*68:01, HLA-B*14:02, and HLA-B*40:02 alleles. Three patients had more than 1 mutation targeting the same HLA allele. Interestingly, HLA-B*14:02 and HLA-B*40:02 were significantly overrepresented in patients with aAA compared with ethnicity-matched controls. Patients who inherited the targeted HLA alleles, regardless of HLA mutation status, had a more severe disease course with more frequent clonal complications as assessed by WES, SNP-A, and metaphase cytogenetics, and more frequent secondary MDS. The finding of recurrent HLA class I mutations provides compelling evidence for a predominant HLA class I-driven autoimmunity in aAA and establishes a novel link between immunogenetics and clonal evolution of patients with aAA.

To summarise age- and intensity-stratified associations between human hookworm infection and anaemia and to quantify the impact of treatment with the benzimidazoles, albendazole and mebendazole, on haemoglobin and anaemia in non-pregnant populations. Electronic databases (MEDLINE, EMBASE, PubMed) were searched for relevant studies published between 1980 and 2009, regardless of language, and researchers contacted about potential data. Haemoglobin concentration (Hb) was compared between uninfected individuals and individuals harbouring hookworm infections of different intensities, expressed as standardised mean differences (SMD) and 95% confidence intervals (CI). Meta-analysis of randomised control trials (RCTs) investigated the impact of treatment on Hb and anaemia. Twenty-three cross-sectional studies, six pre- and post-intervention studies and 14 trials were included. Among cross-sectional studies, moderate- and heavy-intensity hookworm infections were associated with lower Hb in school-aged children, while all levels of infection intensity were associated with lower Hb in adults. Among RCTs using albendazole, impact of treatment corresponded to a 1.89 g/l increase (95%CI: 0.13-3.63) in mean Hb while mebendazole had no impact. There was a positive impact of 2.37 g/l (95%CI: 1.33-3.50) on mean Hb when albendazole was co-administered with praziquantel, but no apparent additional benefit of treatment with benzimidazoles combined with iron supplementation. The mean impact of treatment with benzimidazoles alone on moderate anaemia was small (relative risk (RR) 0.87) with a larger effect when combined with praziquantel (RR 0.61). Anaemia is most strongly associated with moderate and heavy hookworm infection. The impact of anthelmintic treatment is greatest when albendazole is co-administered with praziquantel.

Background & objectives: Fanconi anaemia (FA) is a syndrome with a predisposition to bone marrow failure, congenital anomalies and malignancies. It is characterized by cellular hypersensitivity to cross-linking agents such as mitomycin C (MMC). In the present study, a new approach was selected to investigate FANCA (Fanconi anaemia complementation group A) gene in patients clinically diagnosed with cellular hypersensitivity to DNA cross-linking agent MMC. Methods: Chromosomal breakage analysis was performed to prove the diagnosis of Fanconi anaemia in 318 families. Of these, 70 families had a positive result. Forty families agreed to molecular genetic testing. In total, there were 27 patients with unknown complementary types. Genomic DNA was extracted and total RNA was isolated from fresh whole blood of the patients. The first-strand cDNA was synthesized and the cDNA of each patient was then tested with 21 pairs of overlapping primers. High resolution melting curve analysis was used to screen FANCA, and LinReg software version 1.7 was utilized for analysis of expression. Results: In total, six sequence alterations were identified, which included two stop codons, two frames-shift mutations, one large deletion and one amino acid exchange. FANCA expression was downregulated in patients who had sequence alterations. Interpretation & conclusions: The results of the present study show that high resolution melting (HRM) curve analysis may be useful in the detection of sequence alteration. It is simpler and more costeffective than the multiplex ligation-dependent probe amplification (MLPA) procedure. PMID:27121516

The aim of this study was to estimate the effect of an antihelminthic drug, given at booking and at term to antenatal care visits, on the prevalence of anaemia at term and 4 months post-partum in Rufiji district, Tanzania, the area with high prevalence of intestinal parasites. A cluster randomised controlled trial was conducted on 3080 pregnant women. Out of these 1475 (study arm) received albendazole and 1605 (control arm) placebo. All women also received routine daily iron folate supplements (36 mg iron and 5 mg folate), and sulphadoxine pyramethamine (SP) to prevent malaria. Haemoglobin levels were assessed at booking, at term and 4 months post-partum. At term, median and mean haemoglobin level and the prevalence of severe (anaemia did not differ. The reduction in the prevalence of anaemia from booking to term, was significantly larger in the study arm compared to control arm (26.1% vs. 18.8%; p anaemia (Hb pregnancy. However benefits for deworming may be limited in areas with an antenatal iron supplementation programme or low intensity of hookworm infections and hence future research should be directed towards the cost-effectiveness of the de-worming compared to other interventions for reducing anaemia in pregnancy.

Acquired aplastic anemia (AA) is a hematopoietic stem cell disease that leads to hematopoietic disorder and peripheral blood pancytopenia. We investigated whether nutritional support is helpful to AA recovery. We established a rat model with AA. A nutrient mixture was administered to rats with AA through different dose gavage once per day for 55 d. Animals in this study were assigned to one of five groups: normal control (NC; group includes normal rats); AA (rats with AA); high dose (AA + nutritional mixture, 2266.95 mg/kg/d); medium dose (1511.3 mg/kg/d); and low dose (1057.91 mg/kg/d). The effects of nutrition administration on general status and mitochondrial function of rats with AA were evaluated. The nutrient mixture with which the rats were supplemented significantly improved weight, peripheral blood parameters, and histologic parameters of rats with AA in a dose-dependent manner. Furthermore, we observed that the number of mitochondria in the liver, spleen, kidney, and brain was increased after supplementation by transmission electron microscopy analysis. Nutrient administration also improved mitochondrial DNA content, adenosine triphosphate content, and membrane potential but inhibited oxidative stress, thus, repairing the mitochondrial dysfunction of the rats with AA. Taken together, nutrition supplements may contribute to the improvement of mitochondrial function and play an important role in the recuperation of rats with AA. Copyright © 2017 Elsevier Inc.

Association of anaemia in primary care patients with chronic kidney disease: cross sectional study of quality improvement in chronic kidney disease (QICKD) trial data

Science.gov (United States)

2013-01-01

Background Anaemia is a known risk factor for cardiovascular disease and treating anaemia in chronic kidney disease (CKD) may improve outcomes. However, little is known about the scope to improve primary care management of anaemia in CKD. Methods An observational study (N = 1,099,292) with a nationally representative sample using anonymised routine primary care data from 127 Quality Improvement in CKD trial practices (ISRCTN5631023731). We explored variables associated with anaemia in CKD: eGFR, haemoglobin (Hb), mean corpuscular volume (MCV), iron status, cardiovascular comorbidities, and use of therapy which associated with gastrointestinal bleeding, oral iron and deprivation score. We developed a linear regression model to identify variables amenable to improved primary care management. Results The prevalence of Stage 3–5 CKD was 6.76%. Hb was lower in CKD (13.2 g/dl) than without (13.7 g/dl). 22.2% of people with CKD had World Health Organization defined anaemia; 8.6% had Hb ≤ 11 g/dl; 3% Hb ≤ 10 g/dl; and 1% Hb ≤ 9 g/dl. Normocytic anaemia was present in 80.5% with Hb ≤ 11; 72.7% with Hb ≤ 10 g/dl; and 67.6% with Hb ≤ 9 g/dl; microcytic anaemia in 13.4% with Hb ≤ 11 g/dl; 20.8% with Hb ≤ 10 g/dl; and 24.9% where Hb ≤ 9 g/dl. 82.7% of people with microcytic and 58.8% with normocytic anaemia (Hb ≤ 11 g/dl) had a low ferritin (stores may be depleted in over >60% of people with normocytic anaemia. Prescribing oral iron has not corrected anaemia. PMID:23351270
