The elephant trunk technique for aortic dissection is useful for reducing false lumen pressure; however, a folded vascular prosthesis inside the aorta can cause haemolysis. The purpose of this study was to investigate whether an elephant trunk in a small-calibre lumen can cause haemolysis. Inpatient and outpatient records were retrospectively reviewed. Two cases of haemolytic anaemia after aortic surgery using the elephant trunk technique were identified from 2011 to 2013. A 64-year-old man, who underwent graft replacement of the ascending aorta for acute Stanford type A aortic dissection, presented with enlargement of the chronic dissection of the descending aorta and moderate aortic regurgitation. A two-stage surgery was scheduled. Total arch replacement with an elephant trunk in the true lumen and concomitant aortic valve replacement were performed. Postoperatively, he developed severe haemolytic anaemia because of the folded elephant trunk. The anaemia improved after the second surgery, including graft replacement of the descending aorta. Similarly, a 61-year-old man, who underwent total arch replacement for acute Stanford type A aortic dissection, presented with enlargement of the chronic dissection of the descending aorta. Graft replacement of the descending aorta with an elephant trunk inserted into the true lumen was performed. The patient postoperatively developed haemolytic anaemia because of the folded elephant trunk, which improved after additional stent grafting into the elephant trunk. A folded elephant trunk in a small-calibre lumen can cause haemolysis. Therefore, inserting an elephant trunk in a small-calibre true lumen during surgery for chronic aortic dissection should be avoided. © The Author 2014.

2001-07-01

Full Text Available Immune-mediated haemolytic anaemia (IMHA may be primary or secondary. In primary IMHA, no underlying cause can be found, whereas secondary IMHA is triggered by an underlying cause, such as neoplasia, infectious diseases, or drugs. This paper describes 3 dogs with typical signs of IMHA that was possibly associated with the intestinal parasite Ancylostoma caninum. As intestinal helminths can be difficult to diagnose on faecal examination, it would be pertinent to performmultiple faecal examinations on any animal that has IMHA with no apparent underlying cause, as part of the therapy.

Haemolytic anaemia and acute pancreatitis associated with zinc toxicosis in a dog.

Blundell, R; Adam, F

2013-01-05

We describe a case of zinc toxicity in a 14-month-old, female, neutered, Cavalier King Charles spaniel with a 48-hour history of haematochezia, icterus and collapse. Regenerative anaemia with a packed-cell volume of 7 per cent was seen. Prior to referral, radiography had revealed a gastric, metallic foreign body which was removed at exploratory laparotomy. On presentation, the dog was comatose, hypothermic and bradycardic - resuscitation was performed successfully, but the dog then displayed marked abdominal pain. The dog died 12 hours after presentation. At postmortem examination, the animal showed severe icterus. Both kidneys were diffusely dark red; the pancreas was diffusely pale and nodular. Histopathological examination revealed evidence of intravascular haemolysis with blood vessel lumens containing haemoglobin. The renal tubules also contained large amounts of intraluminal haemoglobin with haemoglobin crystals scattered throughout the cortex and medulla. The pancreas exhibited multifocal coagulative necrosis, surrounded by a neutrophil-dominated inflammatory infiltrate. Zinc levels were markedly increased above the normal reference range in both liver and kidney. This report describes the clinical and pathological findings of a case of acute zinc toxicity in a dog following ingestion of a metallic object which resulted in marked haemolytic anaemia and acute pancreatitis.

The use of the rapid osmotic fragility test as an additional test to diagnose canine immune-mediated haemolytic anaemia

Background: Diagnosing canine immune-mediated haemolytic anaemia (IMHA) is often challenging because all currently available tests have their limitations. Dogs with IMHA often have an increased erythrocyte osmotic fragility (OF), a characteristic that is sometimes used in the diagnosis of IMHA...... hyperlipemic dogs (group 3), 10 dogs with lymphoma (group 4), 8 dogs with an infection (group 5) and 13 healthy dogs (group 6) were included. In all dogs, blood smear examination, in-saline auto-agglutination test, Coombs' test, COFT and ROFT were performed. In the COFT, OF5, OF50 and OF90 were defined...

Full Text Available Background/Aim. We evaluate the impact of combined pentoxifylline and high-dose vitamins E to standard antiviral treatment on RBV-induced haemolytic anaemia. Patients and Methods. Selected 200 naïve chronic HCV patients, were randomized to receive either the standard antiviral therapy (peginterferon α-2b and RBV plus pentoxifylline (800 mg and high-dose vitamin E (1000 iu daily (combined group or received standard antiviral therapy plus placebo only (control group. They were followed up during treatment course and for 6 months posttreatment to assess the occurrence of anaemia and virological response, respectively. Results. RBV dose modification due to anaemia were significantly less in combined group (8.5 versus 21.5%. P<.05.Withdrawal, secondary to sever anemia (Hb<8.5 gm%, was recorded only in 6 (28.6% patients of the control group. Both (ETR and (SVR were significantly higher in combined group than control group by both intention-to-treat analysis (71 versus 56%, P<.05 and 66 versus 49%, P<.05 and per-protocol analysis (85.5 versus 70.9%, P<.05 and 79.5 versus 62%, P<.05. Conclusion. Pentoxifylline and vitamin E can ameliorate RBV-associated haemolysis; improve compliance and virologic clearance when combined with the standard antiviral therapy in patients with chronic hepatitis C.

Full Text Available Abstract Background The aim of this study was to compare a gel-based test with the traditional direct agglutination test (DAT for the diagnosis of immune-mediated haemolytic anaemia (IMHA. Methods Canine (n = 247 and feline (n = 74 blood samples were submitted for DAT testing to two laboratories. A subset of canine samples was categorized as having idiopathic IMHA, secondary IMHA, or no IMHA. Results The kappa values for agreement between the tests were in one laboratory 0.86 for canine and 0.58 for feline samples, and in the other 0.48 for canine samples. The lower agreement in the second laboratory was caused by a high number of positive canine DATs for which the gel test was negative. This group included significantly more dogs with secondary IMHA. Conclusions The gel test might be used as a screening test for idiopathic IMHA and is less often positive in secondary IMHA than the DAT.

Intrauterine intravascular transfusion for fetal haemolytic anaemia: the Western Australian experience.

1992-11-16

To report the first four years' clinical experience with fetal intravascular blood transfusion for the treatment of fetal haemolytic anaemia in Western Australia. King Edward Memorial Hospital, Perth, which is the sole tertiary level perinatal centre in Western Australia with a referral base of approximately 25,000 pregnancies each year. Transfusion was by injection of packed cells from Rh-negative donors into the fetal umbilical vein near the site of insertion into the placenta. Fetal haemoglobin levels were measured before and after each transfusion. In most cases, the fetus was paralysed by intramuscular tubocurarine. Sixty intravenous transfusions were performed in 20 pregnancies. At the time of the initial transfusion, the mean haemoglobin level was 5.8 g/dL (range, 2.5-8.5 g/dL) and six fetuses had signs of hydrops. The case survival rate was 80% and the procedure survival rate was 93%. Three of the deaths occurred in the first five cases. Caesarean section was performed during two of the procedures, one because of bleeding from the cord puncture site and one because of tamponade of the umbilical vessels. Fetal intravascular transfusion is a highly effective treatment for fetal alloimmunisation and allows pregnancies to continue to term and to be delivered vaginally. However, the procedure may be difficult and requires a team approach with ready access to fetal monitoring and emergency caesarean section. Our results suggest that increasing experience of the team is a major factor in improved outcome.

The underlying diagnosis of severe anaemic illnesses in children may not be easy to identify at times, especially when regular blood transfusion has been started. International children patients attending a haematology clinic for diagnostic evaluation were identified retrospectively if they had to receive repeated blood transfusions with an undiagnosed illness or an incorrect diagnosis. Their demographic data, presenting features, and eventual diagnosis were described. Twelve children including 7 boys were enrolled from March 2007 to August 2011. Five came from Vietnam; 2 each came from Bangladesh and Indonesia; and 1 each from Hong Kong, Myanmar, and Ukraine. Their illnesses started at a mean age of 1.5 years (0.1 to 6.6) and they had been receiving blood transfusion for a mean duration of 2.5 years (0.1 to 9.9) years prior to the evaluation. Thalassemia major was the fi rst diagnosis in 5 cases; one had been treated for autoimmune haemolytic anaemia while the rest had not been given a diagnosis. After the evaluation, 4 children were diagnosed with Diamond Blackfan anaemia, 3 were diagnosed with hereditary spherocytosis, and one each with hereditary pyropoikilocytosis, congenital sideroblastic anaemia, congenital thrombotic thrombocytopenic purpura, transient erythroblastopenia of childhood, and autoimmune myelofibrosis associated with human immunodeficiency virus infection. A definitive diagnosis can be identified in this cohort of children on medical tourism with severe anaemic illnesses requiring repeated transfusions with diagnostic approaches that circumvent the interference of transfused cells.

Multiple Autoimmune Propensity and B-Non-Hodgkin Lymphoma: Cause or Effect?

2011-01-01

Full Text Available We report a case of multiple autoimmunity consisting of the presence of autoimmune haemolytic anaemia (AIHA, antimitochondrial antibodies (AMAs, and antiphospholipid antibodies (APLAbs as the presenting manifestations of an extrahepatic B-non-Hodgkin lymphoma (B-NHL in a 63-year-old woman. The patient presented with fatigue attributed to severe AIHA. Due to increased serum IgM and -GT levels, an investigation for AMA was performed, which proved positive with anti-M2 specificity. A prolongation of activated partial thromboplastin time (aPTT led to the determination of APLAbs (lupus anticoagulant and other APLAbs which were also positive. Bone marrow biopsy in combination with immmunohistochemical studies established the diagnosis of lymphoplasmacytic B-NHL. Ten months later, B-NHL was in remission while AMA and APLAbs were still positive. In conclusion, we documented the coexistence of multiple autoimmune reactions together with B-NHL highlighting the possible common pathogenetic pathways of the two entities.

We report on the complete absence of protein 4.2 in two Tunisian siblings. The propositus presented with a haemolytic anaemia that evolved in an intermittent fashion until she was cured by splenectomy. Her red cells had a normal morphology, as well as normal deformability upon osmotic gradient ektacytometry. SDS-polyacrylamide gel electrophoresis failed to reveal any protein 4.2. Using anti-protein 4.2 polyclonal antibodies. Western blots were also unable to detect protein 4.2. Preparation of inside out vesicles resulted in no detectable loss of ankyrin. The propositus's sister presented with a haemolytic anaemia but had not undergone splenectomy; she showed the same biochemical features. The two cases presented of missing protein 4.2 are the first ones to be described outside the Japanese population. Considered as homozygotes for some defect that must alter the protein 4.2 gene itself, they exemplify a unique syndrome pertaining neither to elliptocytosis nor to spherocytosis, at least not closely. The parents, who are first cousins and whom we regarded as heterozygotes, were clinically and morphologically normal; they had a normal content of protein 4.2. Therefore, the 4.2 (-) haemolytic anaemia appears as entirely recessive.

Anaemia in pregnancy.

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.

The parameters of 51 Cr labelled red cell survival curves were calculated in 26 patients with homozygous β-thalassaemia, 8 with sickle-cell anaemia and 3 with s-β-thalassaemia, using a non-linear weighted least squares analysis computer program. In thalassaemic children the calculated parameters denote that the shorting of the mean cell life is due to early senescence alone, while there is some evidence that in thalassaemic adults additional extracellular destruction mechanisms participate as well. Red cell survival curves from patients with sickle-cell anaemia and s-β-thalassaemia resemble each other, while their parameters indicate an initial rapid loss of radioactivity, early senescence and the presence of extracellular red cell destruction factors.

Prepartum anaemia: prevention and treatment.

Science.gov (United States)

Milman, Nils

2008-12-01

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

Autoimmune diseases are chronic conditions initiated by the loss of immunological tolerance to self-antigens. They constitute heterogeneous group of disorders, in which multiple alterations in the immune system result in a spectrum of syndromes that either target specific organs or affect the body systematically. Recent epidemiological studies have shown a possible shift of one autoimmune disease to another or the fact that more than one autoimmune disease may coexist in a single patient or in the same family. Numerous autoimmune diseases have been shown to coexist frequently with thyroid autoimmune diseases. AUTOIMMNUNE THYROID DISEASE AND OTHER ORGAN SPECIFIC NON-ENDOCRINE AUTOIMMUNE DISEASES: This part of the study reviews the prevalence of autoimmune thyroid disease coexisting with: pernicious anaemia, vitiligo, celiac disease, autoimmune liver disease, miastenia gravis, alopecia areata and sclerosis multiplex, and several recommendations for screening have been given. AUTOIMMUNE THYROID DISEASE AND OTHER ORGAN NON-SPECIFIC NON-ENDOCRINE AUTOIMMUNE DISEASES: Special attention is given to the correlation between autoimmune thyroid disease and rheumatoid arthritis, systemic lupus erythematosus, syndrome Sjögren, systemic sclerosis and mixed connective tissue disease. Screening for autoimmune thyroid diseases should be recommended in everyday clinical practice, in patients with primary organ-specific or organ non-specific autoimmune disease. Otherwise, in patients with primary thyroid autoimmune disease, there is no good reason of seeking for all other autoimmune diseases, although these patients have a greater risk of developing other autoimmune disease. Economic aspects of medicine require further analyzing of these data, from cost/benefit point of view to justified either mandatory screening or medical practitioner judgment.

2011-12-01

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.

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 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.

Full Text Available Monogenic primary immunodeficiency syndromes can affect one or more endocrine organs by autoimmunity during childhood. Clinical manifestations include type1 diabetes mellitus, hypothyroidism, adrenal insufficiency and vitiligo. LPS-responsive beige-like anchor protein (LRBA deficiency was described in 2012 as a novel primary immunodeficiency, predominantly causing immune dysregulation and early onset enteropathy. We describe the heterogeneous clinical course of LRBA deficiency in two siblings, mimicking an autoimmune polyendocrine disorder in one of them in presence of the same underlying genetic mutation. The third child of consanguineous Egyptian parents (Patient 1 presented at six months of age with intractable enteropathy and failure to thrive. Later on he developed symptoms of adrenal insufficiency, autoimmune haemolytic anaemia, thrombocytopenia, and infectious complications due to immunosuppressive treatment. The severe enteropathy was non-responsive to the standard treatment and led to death at the age of 22 years. His younger sister (Patient 2 presented at the age of 12 to the endocrinology department with decompensated hypothyroidism, perioral vitiligo, delayed pubertal development, and growth failure without enteropathy and immunodeficiency.Using whole-exome sequencing (WES we identified a homozygous frameshift mutation (c.6862delT, p.Y2288MfsX29 in the LRBA gene in both siblings. To our knowledge our patient (patient 2 is the first case of LRBA deficiency described with predominant endocrine phenotype without immunodeficiency and enteropathy. LRBA deficiency should be considered as underlying disease in pediatric patients presenting with autoimmune endocrine symptoms. The same genetic mutation can manifest with a broad phenotypic spectrum without genotype-phenotype correlation. The awareness for disease symptoms among non-immunologists might be a key to early diagnosis. Further functional studies in LRBA deficiency are necessary to

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.

Severe aplastic anaemia and Grave's disease in a paediatric patient.

Science.gov (United States)

Kumar, Manjusha; Goldman, Jeffrey

2002-07-01

Severe aplastic anaemia (SAA) is considered to be an autoimmune disorder affecting the haematopoietic cells and most often is idiopathic. An association between SAA and other autoimmune diseases is rare and has been described in adults for eosinophilic fasciitis, thymomas, systemic lupus erythematosus and thyroid disorders. We describe the first paediatric patient with chronic relapsing SAA and Grave's disease. We discuss the difficulty in diagnosis of Grave's disease, the possibility of its manifestation due to withdrawal of immunosuppressants, and issues to consider in the treatment of this disease in the setting of bone marrow failure.

One month previously, a 28-year old male underwent an emergency modified Bentall procedure because of Marfan syndrome with acute aortic dissection Stanford Class A. Computed tomography of the chest did not reveal severe graft stenosis of the anastomosis. To explore the cause of anaemia, renal dysfunction and macroscopic haematuria, the patient was tested for antineutrophil cytoplasmic antibody (ANCA)-associated systemic vasculitis (AASV). Antimyeloperoxidase antibodies (MPO)-ANCA and antiproteinase 3 antibodies (PR3)-ANCA were strongly positive. Corticosteroid therapy was applied, followed by cyclophosphamide and azathioprine. In response to treatment, the MPO-ANCA and PR3-ANCA levels gradually decreased, proteinuria was alleviated and haemoglobin levels returned to normal after 6 months. This is the first report to highlight haemolytic anaemia and AASV with Marfan syndrome after surgery for aortic dissection.

Intracellular haemolytic agents of Heterocapsa circularisquama exhibit toxic effects on H. circularisquama cells themselves and suppress both cell-mediated haemolytic activity and toxicity to rotifers (Brachionus plicatilis).

A harmful dinoflagellate, Heterocapsa circularisquama, is highly toxic to shellfish and the zooplankton rotifer Brachionus plicatilis. A previous study found that H. circularisquama has both light-dependent and -independent haemolytic agents, which might be responsible for its toxicity. Detailed analysis of the haemolytic activity of H. circularisquama suggested that light-independent haemolytic activity was mediated mainly through intact cells, whereas light-dependent haemolytic activity was mediated by intracellular agents which can be discharged from ruptured cells. Because H. circularisquama showed similar toxicity to rotifers regardless of the light conditions, and because ultrasonic ruptured H. circularisquama cells showed no significant toxicity to rotifers, it was suggested that live cell-mediated light-independent haemolytic activity is a major factor responsible for the observed toxicity to rotifers. Interestingly, the ultrasonic-ruptured cells of H. circularisquama suppressed their own lethal effect on the rotifers. Analysis of samples of the cell contents (supernatant) and cell fragments (precipitate) prepared from the ruptured H. circularisquama cells indicated that the cell contents contain inhibitors for the light-independent cell-mediated haemolytic activity, toxins affecting H. circularisquama cells themselves, as well as light-dependent haemolytic agents. Ethanol extract prepared from H. circularisquama, which is supposed to contain a porphyrin derivative that displays photosensitising haemolytic activity, showed potent toxicity to Chattonella marina, Chattonella antiqua, and Karenia mikimotoi, as well as to H. circularisquama at the concentration range at which no significant toxicity to rotifers was observed. Analysis on a column of Sephadex LH-20 revealed that light-dependent haemolytic activity and inhibitory activity on cell-mediated light-independent haemolytic activity existed in two separate fractions (f-2 and f-3), suggesting that both

Leaves of Veronia amygdalina were extracted using ethanol and aqueous extraction respectively. The physico-chemical analysis of the extracts revealed that both extracts had darkish brown colour, sweetish bitter taste, pungent smell, positive froth and haemolytic test, this indicated the presence of saponin in both extracts. The result of the haemolytic assay revealed that blood group-O had the highest susceptibility to the saponin-induced haemolysis, while blood group-A had the least susceptibility to haemolysis among the blood groups tested. Genotype-AA had the highest resistant to haemolysis by Vernonia amygdalina saponin induced haemolysis, while genotype-SS had the least resistant to haemolysis among the genotype tested. Furthermore the ethanol extract had a higher haemolytic activity than the aqueous extract on the various human erythrocyte analysed. This study revealed that Vernonia amygdalina had haemolytic substance, this substance had a high haemolytic effect on blood group-O and genotype-SS. The active haemolytic substance in both extracts was identified to be saponin. (author)

Basic principles in the therapy of idiopathic autoimmune hemolytic anemia induced by warm antibody were glucocorticoides and splenectomy. Immunosupresive drugs, plasmaferesis and intravenous high doses gamma globulin therapy are also useful. In secundary autoimmune hemolytic anemia induced by warm antibody we treated basic illness. During the period of 1990-1992 we treated 21 patients with primary autoimmune hemolytic anemia and 6 patients with secondary /4 CLL and 2 Non-Hodgkin's lymphoma/. Complete remission we found as a normalisation of reticulocites and hemoglobin level respectively. Complete remission by corticoides we got in 14/21 patients, partial response in 2/21 respectively. Complete response by splenectomy we got in 2/3 splenoctomized patients (idiopathic type). For successful treatment secondary hemolytic anemias we treated primary diseases (CLL and malignant lymphoma) and we got in 4/6 patients complete remission. Our results were standard in both type of autoimmune hemolytic anaemias induced by warm antibody.

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

2012-02-03

Recurrent gastrointestinal haemorrhage is an uncommon manifestation of systemic sclerosis. We report a case of gastrointestinal bleeding due to gastric antral vascular ectasia (GAVE) in a patient with systemic sclerosis. Failure to recognise the condition as a cause of gastrointestinal bleeding may delay the instigation of appropriate treatment. GAVE should be considered in the differential diagnosis of anaemia in patients with autoimmune conditions such as systemic sclerosis and primary biliary cirrhosis.

2014-06-01

Full Text Available Osteopoikilosis is an uncommon hereditary dysplasia of skeleton characterized by small sclerotic foci clustered mainly in periarticular osseus regions. The radiographic pattern is pathognomonic. The disease can be a result of the loss-of-function mutations in LEMD3 – the gene responsible for bone density which can influence also on the expression of transforming growth factor β1 (TGF-β1 signalling. TGF-β1 is a key mediator of fibrosis and a modulator of immune responses. Patients with osteopoikilosis demonstrate a higher incidence of keloid formation and autoimmune diseases. In the presented case osteopoikilosis was associated with keloids formation and autoimmune diseases: rheumatoid arthritis, myasthenia, Graves’ disease and megaloblastic anaemia.

The prevalence of coeliac disease among patients with autoimmune hypothyroidism has not been studied before in Jordan and other Arab countries. A cross-sectional record-based review was made of all adult autoimmune hypothyroidism patients who attended a referral centre in Jordan, during an 8-month period. Coeliac disease in these patients was diagnosed by the attending physician based on positive serological tests for anti-endomysial antibodies IgA and IgG followed by duodenal biopsy to confirm the diagnosis of coeliac disease. Of 914 patients recruited, 117 (12.8%) were seropositive for coeliac disease. Of 87 seropositive patients who underwent duodenal biopsy, 39 had positive histological findings of coeliac disease (44.8%). Extrapolating from these findings the overall rate of coeliac disease among autoimmune hypothyroidism patients was estimated to be 5.7%. In multivariate logistic regression coeliac disease was significantly associated with older age (> 40 years), presence of other autoimmune diseases, vitamin B12 deficiency and anaemia.

International Nuclear Information System (INIS)

Saboor, M.; Moinuddin, A.; Naureen, A.

2012-01-01

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)

Haemolytic activity of uranium compounds haemolysis by thermochemical derivatives of ammonium uranate

International Nuclear Information System (INIS)

Stuart, W.I.; Tucker, A.D.; Adams, R.B.

1975-01-01

A study has been made of the haemolytic action on human erythrocytes by ammonium uranate (AU) and various thermochemical products of AU. These products were obtained by heating AU in hydrogen at 5 0 C min -1 to various temperatures. Haemolysis has been interpreted in terms of a diffusion model which for each product yields a single parameter Ksub(N), the haemolytic activity factor. The magnitude of Ksub(N) is a convenient measure of the ability of a powder to damage erythrocytes. The haemolytic activity of certain thermochemical derivatives indicates an exceptionally high potential for damage to erythrocytes. Infrared and thermoanalytical measurements have shown that the high activity of these products derives principally from a self-reduction reaction, induced by heating AU to 400-420 0 C in hydrogen.

1998-03-01

Glycoglycerolipids derived from microalgae can be a source of biologically active substances including toxins. Such glycolipids were analysed in two isolates of toxic marine dinoflagellates from European waters. The lipids of Gymnodinium mikimotoi contained 17% of monogalactosyl diacylglycerol (MGDG) and digalactosyl diacylglycerol (DGDG), while in Gymnodinium sp. the proportion was 35%. MGDG and DGDG from both species were haemolytic. The major unsaturated fatty acid in both algal glycolipids was 18:5 omega 3.

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.

The strong haemolytic activity of Pulsatilla saponin A (PSA), D (PSD) hampered their clinical development of antitumor agents. In order to solve this problem, C-28 position modification derivatives of PSA/PSD were synthesized. The cytotoxicity and haemolytic activity of these compounds were evaluated. Structure-activity relationship and structure-toxicity relationship had been observed. The mice acute toxicity of compound 11 was reduced greatly than that of PSA. This study indicates that compound 11 may represent an interesting class of potent antitumor agents from triterpenoid saponins avoiding the haemolysis problem. The present study has important significance for the development of antitumor saponins. Copyright © 2015 Elsevier Ltd. All rights reserved.

Use of intravenous immunoglobulin in neonates with haemolytic disease and immune thrombocytopenia

2013-01-01

Full Text Available Background/Aim. Intravenous immunoglobulin is a blood product made of human polyclonal immunoglobulin G. The mode of action of intravenous immunoglobulin is very complex. It is indicated in treatment of neonatal immune thrombocytopenia and haemolytic disease of the newborn. The aim of the study was to present our experience in the use of intravenous immunoglobulin in a group of term neonates. Methods. We analysed all relevant clinical and laboratory data of 23 neonates who recieved intravenous immunoglobulin during their hospitalization in Neonatal Intensive Care Unit of Mother and Child Health Care Institute over a five year period, from 2006. to 2010. Results. There were 11 patients with haemolytic disease of the newborn and 12 neonates with immune thrombocytopenia. All of them recieved 1-2 g/kg intravenous immunoglobulin in the course of their treatment. There was no adverse effects of intravenous immunoglobulin use. The use of intravenous immunoglobulin led to an increase in platelet number in thrombocytopenic patients, whereas in those with haemolytic disease serum bilirubin level decreased significantly, so that some patients whose bilirubin level was very close to the exchange transfusion criterion, avoided this procedure. Conclusion. The use of intravenous immunoglobulin was shown to be an effective treatment in reducing the need for exchange transfusion, duration of phototherapy and the length of hospital stay in neonates with haemolytic disease. When used in treatment of neonatal immune thrombocytopenia, it leads to an increase in the platelet number, thus decreasing the risk of serious complications of thrombocytopenia.

Acute pancreatitis : a newly recognised potential complication of canine babesiosis

Directory of Open Access Journals (Sweden)

A.J. Möhr

2000-07-01

Full Text Available This retrospective study describes 4 cases of canine babesiosis with histologically confirmed acute pancreatitis. In addition, 16 dogs with babesiosis are reported with serum amylase (>3500 U/l and/or lipase (>650 U/l activity elevations of a magnitude that would support a diagnosis of probable acute pancreatitis, although extra-pancreatic sources of the enzymes could not be excluded in these cases. Median time of pancreatitis diagnosis was 2.5 days post-admission, with primarily young (median age 3 years, sexually intact dogs affected. The development of pancreatitis was unrelated to the degree of anaemia at time of admission. In addition to pancreatitis, 80 % of cases suffered from other babesial complications, namely icterus (13, acute respiratory distress syndrome (6, immune-mediated haemolytic anaemia (6, renal failure (3, haemoconcentration (2 and cerebral syndrome (2. Acute respiratory distress syndrome, renal failure and cerebral syndrome were associated with a poor prognosis, with 4 of the 5 dogs included in the overall 26 % mortality rate having at least 1 of these complications. Haemolytic anaemia with ischaemia-reperfusion injury to the pancreas is proposed as a possible primary pathophysiological mechanism in babesial pancreatitis. Hypotensive shock, immune-mediated haemolytic anaemia, haemoconcentration and possibly altered lipid metabolism in babesiosis may also be involved. The previously postulated pro-inflammatory cytokine milieu of complicated babesiosis may underlie the progression, if not the primary initiation, of pancreatic pathology. Acute pancreatitis may represent the previously reported 'gut' form of babesiosis.

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.

Cerebral microcirculation during experimental normovolaemic anaemia

Directory of Open Access Journals (Sweden)

Judith eBellapart

2016-02-01

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.

The purpose of current study was to purify and partially depolymerize guar gum by β-mannanase, HCl, Ba(OH) 2 actions and subjected to inspect compositional, thermogravimetric analysis (TGA) and haemolytic activity. Chemical composition revealed mannose and galactose ratio remained un-altered even after process of purification and hydrolysis. TGA thermograms affirmed initial and final decomposition temperature in various zones. Major decomposition stages apparently revealed partially hydrolyzed guar gum (PHGG) exhibited better heat stable properties having more zones of degradation than crude one. Furthermore, all guar fractions (2.5-250 mg/mL) were subjected to haemolysis to evaluate toxic effects during process of hydrolysis. The crude and hydrolyzed guar galactomannans exhibited minor haemolytic activity (1.9 ± 0.03-7.24 ± 0.02%) when compared to 0.1% Triton-X 100 (100% haemolysis) showing no toxic effects to human RBC's. Conclusively, hydrolyzed guar-galactomannans are safe and can be used in food products with improved heat stability.

Type 1 narcolepsy is a neurological disorder characterized by excessive daytime sleepiness and cataplexy associated with the HLA allele DQB1*06:02. Genetic predisposition along with external triggering factors may drive autoimmune responses, ultimately leading to the selective loss of hypocretin-positive neurons. The aim of this study was to investigate potential aetiological factors in Swedish cases of postvaccination (Pandemrix) narcolepsy defined by interferon-gamma (IFNγ) production from immune cells in response to molecularly defined targets. Cellular reactivity defined by IFNγ production was examined in blood from 38 (HLA-DQB1*06:02(+) ) Pandemrix-vaccinated narcolepsy cases and 76 (23 HLA-DQB1*06:02(+) and 53 HLA-DQB1*06:02(-) ) control subjects, matched for age, sex and exposure, using a variety of different antigens: β-haemolytic group A streptococcal (GAS) antigens (M5, M6 and streptodornase B), influenza (the pandemic A/H1N1/California/7/09 NYMC X-179A and A/H1N1/California/7/09 NYMC X-181 vaccine antigens, previous Flu-A and -B vaccine targets, A/H1N1/Brisbane/59/2007, A/H1N1/Solomon Islands/3/2006, A/H3N2/Uruguay/716/2007, A/H3N2/Wisconsin/67/2005, A/H5N1/Vietnam/1203/2004 and B/Malaysia/2506/2004), noninfluenza viral targets (CMVpp65, EBNA-1 and EBNA-3) and auto-antigens (hypocretin peptide, Tribbles homolog 2 peptide cocktail and extract from rat hypothalamus tissue). IFN-γ production was significantly increased in whole blood from narcolepsy cases in response to streptococcus serotype M6 (P = 0.0065) and streptodornase B protein (P = 0.0050). T-cell recognition of M6 and streptodornase B was confirmed at the single-cell level by intracellular cytokine (IL-2, IFNγ, tumour necrosis factor-alpha and IL-17) production after stimulation with synthetic M6 or streptodornase B peptides. Significantly, higher (P = 0.02) titres of serum antistreptolysin O were observed in narcolepsy cases, compared to vaccinated controls. β-haemolytic GAS may be

Aplastic anaemia is rear disease caused by destruction of pluripotent stem cells in bone marrow. Pregnancy is one of the main factor that lead to immunosuppression. During pregnancy aplastic anaemia could be life-threatening for both mother and child, because of the variety of complications like bleeding and infections. We introduce the first case of pregnant woman with aplastic anaemia in Bulgaria. The woman was diagnosed in 12-13 gestational week. All biometric characteristics of the foetus were normal. The patient was consulted with oncohaematologists, pediatricians, specialists of Obstetrics and Gynaecology, and intensivists. Methylprednisolone, antibiotics, packed cells and platelet transfusions were initiated. However, the moment for interruption of the pregnancy was missed (first trimester). The woman developed a fever and vomited bloody material. Despite the optimal supportive treatment, the patient died. The pathoanatomy diagnose is Aplastic anaemia, induced by the pregnancy. From our experience with that case and other references from the literature we conclude that all pregnant woman with aplastic anaemia should interrupt their pregnancy during first trimester. In those patients who are diagnosed at later terms of pregnancy very supportive infusions and immunosuppressive therapy should be made, including antithymocyte globulin and/or cyclosporine. Women with no improvement from that therapy should achieve a bone-marrow transplantation.

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.

Full Text Available Introduction. Biliary calculosis is rare in children. It occurs associated with different haemolytic and non-haemolytic disorders, which are sometimes also combined. Case Outline. A 15-year-old male was hospitalized due to biliary calculosis and non-conjugated hyper-bilirubinemia. A mild non-conjugated hyperbilirubinemia, without anaemia and other symptoms of liver dysfunction, was registered at age 8 years, and 7 years later cholelithiasis with transitory choledocholithiasis. The finding of ellyptocytes in blood smear, which was also verified in mother, normal haemoglobin count and the absence of diseases followed by secondary dysmorphic erythrocytes of this type, indicated a clinically milder (compensated hereditary ellyptocytosis, while more than a double increase of non-conjugated serum bilirubin fracture after a three-day hypocaloric diet (400 kcal per day showed the concurrent presence of Gilbert’s syndrome. In the laparascopically removed gallbladder a larger number of small pigmented calculi were disclosed. Conclusion. Gilbert’s syndrome is an essential precipitating factor of biliary calculosis in patients with chronic haemolytic condition. Thus, in all cases of biliary calculosis and non-conjugated hyperbilirubinemia with absent clinical and laboratory parameters of liver disorders and anaemia, except in compensated haemolytic disease and Gilbert’s syndrome as isolated disorders, a possibility of their association should be taken into consideration.

Sickle cell disease (SCD) is an inherited abnormality of the ss-globin chain, which causes a spectrum of haemolytic anaemias. Clinical manifestations in SCD include anaemia, jaundice, recurrent vaso-occlusive crises, and infections (particularly by encapsulated bacteria) due to functional asplenia and cerebrovascular accidents. Radiological investigations play a critical role both in the diagnosis and in the primary prevention of the complications of SCD

Parents are encouraged to discuss self-care with children affected by G6PD deficiency; however, little is known about the extent or impact of these discussions on the physical and psychosocial health of these children. The purpose of this study was to examine the nature of parental-child discussions of G6PD deficiency self-care and their relationship to child health. A quantitative cross-sectional survey of 178 Taiwanese parents of children with G6PD deficiency was conducted. The extent of parental-child self-care discussions was assessed in regards to coverage of nine key topics. Parent's G6PD deficiency status, knowledge of haemolytic anaemia symptoms and reported G6PD deficiency education from providers were examined as correlates of parental discussion. Child health was assessed with the child health questionnaire-parent form (Chinese version) and a 13-item haemolytic anaemia symptom list. Self-care discussions were positively correlated with parental G6PD deficiency status (β=2.08, p=0.03), accurate identification of haemolytic anaemia symptoms (β=0.18, p=0.01), the thoroughness and clarity of patient education (β=0.14, pchild age (β=1.04, pchild health (β=1.18, pchild G6PD deficiency self-care discussions are associated with better child health, and parental involvement in these discussions is facilitated by the thoroughness and clarity of patient education received from providers.

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.

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. Laboratory and clinical data in pregnancy, anaemia (Hbpregnancy, 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 (panaemia in pregnancy and postdelivery. In conclusion, anaemia was most common among women in the advanced stage of HIV infection (CD4anaemia.

Acquired aplastic anaemia is one of the important causes of pancytopenia. This study was conducted to observe the mode of presentation of acquired aplastic anaemia and to find out its possible etiological factors. Methods: It is a hospital based descriptive study of 100 patients of acquired aplastic anaemia. Results: Out of 100 patients 60 were male and 40 female. Majority (44%) of the patients were between 12 - 20 years of age. Patient presented with variable symptoms majority (40%) with fever. Most of the patients had haemoglobin levels between 4 - 6 gm/dl. (53%). Seventy percent of the cases had no obvious cause, while in 30% some known causative factors were found. Chloramphenicol was found to be the most common causative drug. Mortality was 35%. Thirty patients were partially treated and 15 were lost to follow up. Twenty patients showed improvement with treatment. Conclusions: Acquired aplastic anaemia is common among males and more prevalent in younger age group. It is idiopathic in 70% cases while 30% had some cause. It has very high mortality. Doctors need to keep in mind this fatal condition in patients presenting with anaemia and should properly investigate before prescribing antibiotics and haematinics. (author)

Full Text Available Objective. This investigation aimed to study the presence of Streptococcus spp. in tilapia (Oreochromis niloticus from fish farm located in Sullana-Piura, Peru. Materials and methods. 150 fish with clinical signs of streptococcal disease were sampled, and the bacterium isolation was performed on blood agar, correlated to histopathological lesions description and molecular confirmation by real-time PCR. Results. The necropsy revealed exophthalmia, hyphema, congestion and/or haemorrhagic meninges, ascites, splenomegaly, hepatomegaly and diffuse haemorrhagic zones throughout the body. 102 isolated positives (54 tilapias to Streptococcus spp. were identified in the microbiological analysis (prevalence of 26%, the brain was the organ with the highest percentage of this bacteria (34.31%, and 19 isolates were beta-haemolytic (18.63% with prevalence of 10.12%. Fish beta-haemolytic streptococci presented epicarditis, perisplenitis and chronic meningitis, panophthalmitis, coagulative necrosis of skeletal muscle and granulomas formation. In the confirmatory test by real-time PCR, any positive tilapia to S. iniae was obtained. The results were analysed using a stochastic simulation of beta distribution using @Risk program uncertainty, reporting an average prevalence of 0.66% in sick tilapias. Conclusions. The analysed fishes were positive to bacteria of the genus Streptococcus, which confirms its presence in the fish farm. However, 19 isolates were beta-haemolytic, and the presence of S. iniae was not positive to the limit prevalence of 2.7% in real-time PCR.

Our purpose was to compile information on the haematological manifestations of systemic lupus erythematosus (SLE), namely leucopenia, lymphopenia, thrombocytopenia, autoimmune haemolytic anaemia (AIHA), thrombotic thrombocytopenic purpura (TTP) and myelofibrosis. During our search of the English-language MEDLINE sources, we did not place a date-of-publication constraint. Hence, we have reviewed previous as well as most recent studies with the subject heading SLE in combination with each manifestation. Neutropenia can lead to morbidity and mortality from increased susceptibility to infection. Severe neutropenia can be successfully treated with granulocyte colony-stimulating factor. While related to disease activity, there is no specific therapy for lymphopenia. Severe lymphopenia may require the use of prophylactic therapy to prevent select opportunistic infections. Isolated idiopathic thrombocytopenic purpura maybe the first manifestation of SLE by months or even years. Some manifestations of lupus occur more frequently in association with low platelet count in these patients, for example, neuropsychiatric manifestation, haemolytic anaemia, the antiphospholipid syndrome and renal disease. Thrombocytopenia can be regarded as an important prognostic indicator of survival in patients with SLE. Medical, surgical and biological treatment modalities are reviewed for this manifestation. First-line therapy remains glucocorticoids. Through our review, we conclude glucocorticoids do produce a response in majority of patients initially, but sustained response to therapy is unlikely. Glucocorticoids are used as first-line therapy in patients with SLE with AIHA, but there is no conclusive evidence to guide second-line therapy. Rituximab is promising in refractory and non-responding AIHA. TTP is not recognised as a criteria for classification of SLE, but there is a considerable overlap between the presenting features of TTP and SLE, and a few patients with SLE have concurrent

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.

[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.

Epidemiological studies support a hypothesis that pulmonary hypertension (PH) is a common complication of sickle cell disease (SCD) that is associated with a high risk of death and evolves as a complication of haemolytic anaemia. This fundamental hypothesis has been recently challenged and remains controversial. In order to further test this hypothesis in a large and independent cohort of SCD patients we obtained plasma samples from the Cooperative Study of Sickle Cell Disease (CSSCD) for analysis of a biomarker, N-terminal-pro brain natriuretic peptide (NT-proBNP), which is elevated in the setting of pulmonary arterial and venous hypertension. A NT-pro-BNP value previously identified to predict PH in adults with SCD was used to determine the association between the risk of mortality in 758 CSSCD participants (428 children and 330 adults). An abnormally high NT-proBNP level ≥160ng/l was present in 27·6% of adult SCD patients. High levels were associated with markers of haemolytic anaemia, such as low haemoglobin level (P<0·001), high lactate dehydrogenase (P<0·001), and high total bilirubin levels (P<0·007). A NT-proBNP level ≥160ng/l was an independent predictor of mortality (RR 6·24, 95% CI 2·9-13·3, P<0·0001). These findings provide further support for an association between haemolytic anaemia and cardiovascular complications in this patient population. © 2011 Blackwell Publishing Ltd.

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.

Aplastic anaemia is a rare haematological disorder characterized by pancytopenia with a hypocellular bone marrow. It may be inherited/genetic or acquired. Acquired aplastic anaemia has been linked to many drugs, chemicals and viruses. Cytogenetic abnormalities have been reported infrequently with acquired aplastic anaemia. Majority of the studies are in adult patients from the West. We report here cytogenetic studies on paediatric patients with acquired aplastic anaemia seen in a tertiary care hospital in north India. Patients (n=71, age 4-14 yr) were diagnosed according to the guidelines of International Agranulocytosis and Aplastic Anaemia Study. Conventional cytogenetics with Giemsa Trypsin Giemsa (GTG) banding was performed. Karyotyping was done according to the International System for Human Cytogenetics Nomenclature (ISCN). Of the 71 patients, 42 had successful karyotyping where median age was 9 yr; of these 42, 27 (64.3%) patients had severe, nine (21.4%) had very severe and six (14.3%) had non severe aplastic anaemia. Five patients had karyotypic abnormalities with trisomy 12 (1), trisomy 8 (1) and monosomy 7 (1). Two patients had non numerical abnormalities with del 7 q - and t (5:12) in one each. Twenty nine patients had uninformative results. There was no difference in the clinical and haematological profile of patients with normal versus abnormal cytogenetics although the number of patients was small in the two groups. Five (11.9%) patients with acquired aplastic anaemia had chromosomal abnormalities. Trisomy was found to be the commonest abnormality. Cytogenetic abnormalities may be significant in acquired aplastic anaemia although further studies on a large sample are required to confirm the findings.

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.

Guidelines for the management of vaginal discharge mention Candida albicans, Trichomonas vaginalis, bacterial vaginosis, Chlamydia trachomatis and Neisseria gonorrhoeae as causes and do not recommend full microbiological culture. The role of non-group B beta-haemolytic streptococci in vaginal cultures is unclear, except for group A streptococci that are known to cause vulvovaginitis in children. In a case-control study, we investigated the association between non-group B beta-haemolytic streptococci and vulvovaginitis in adult women. Cases were women with recurrent vaginal discharge from whom a sample was cultured. Controls were asymptomatic women who consented to submitting a vaginal swab. Group A streptococci were isolated from 49 (4.9%) of 1,010 cases and not from the 206 controls (P < 0.01). Isolation rates of group C, F and G streptococci were low and did not differ statistically between cases and controls. Group A beta-haemolytic streptococci are associated with vaginal discharge in adult women. The other non-group B streptococci require more study. For the adequate management of vaginal discharge, culturing is necessary if initial treatment fails. Guidelines should be amended according to these results.

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).

Iron deficiency anaemia in Sri Lanka

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

In a random test of 100 patients with hyperthyroidism with clinical and paraclinical ascertainment of the diagnosis in 38 cases normo-hypochromic, normocytary anaemias of different expression were found. In the patients with anaemia the serum hormone values were statistically significantly higher than in the 62 patients without anaemia. Also cardiotoxic and hepatotoxic findings were more frequently to be proved in patients with anaemia. A causal iron deficiency, deficit of vitamin B12 or folic acid as well as a haemolytic component of the induction of anaemia could vastly be excluded. By means of the treatment of the basic disease and metabolic balance a normalisation of hemoglobin was achieved without additional medication. From the results of the examinations is concluded that above all a thyreotoxic damage is responsible for the development of the anaemia. In cases of oligo-symptomatic hyperthyroidism part from hepatotoxicity and cardiotoxicity also anaemias may become a leading symptom.

2010-01-01

Full Text Available Introduction. Coeliac disease (CD is a permanent intolerance of gluten, i.e. of gliadin and related proteins found in the endosperm of wheat, rye and barley. It is characterized by polygenic predisposition, autoimmune nature, predominantly asymptomatic or atypical clinical course, as well as by high prevalence in patients with Down's syndrome (DS and some other diseases. Outline of Cases. We are presenting a girl and two boys, aged 6-7 (X=6.33 years with DS and CD recognized under the feature of sideropenic anaemia resistant to oral therapy with iron. Beside mental retardation, low stature and the morphological features characteristic of DS, two patients had a congenital heart disease; one ventricular septal defect and the other atrioventricular canal. In two patients, trisomy on the 21st chromosome pair (trisomy 21 was disclosed in all cells, while one had a mosaic karyotype. All three patients had classical laboratory parameters of sideropenic anaemia: blood Hb 77-89 g/l (X=81.67, HCT 0.26-0.29% (X=0.28, MCV 69-80 fl (X=73, MCH 24.3-30 pg (X=26.77 and serum iron 2-5 μmol/L (X=4.0. Beside anaemia and in one patient a mild isolated hypertransaminasemia (AST 67 U/l, ALT 62 U/l, other indicators of CD were not registered in any of the children. In addition, in all three patients, we also detected an increased level of antibodies to tissue transglutaminase (atTG of IgA class (45-88 U/l so that we performed endoscopic enterobiopsy in order to reliably confirm the diagnosis of CD. In all three patients, the pathohistological finding of the duodenal mucosa specimen showed mild to moderate destructive enteropathy associated with high intraepithelial lymphocyte infiltration, cryptic hyperplasia and lympho-plasmocytic infiltration of the stroma. In all three patients, the treatment with a strict gluten-free diet and iron therapy applied orally for 3-4 months resulted in blood count normalization and the correction of sideropenia.

To estimate the prevalence of Group A beta-haemolytic streptococcus (GAS) and non-GAS infections among children with acute pharyngotonsillitis in Aden, Yemen, to evaluate the value of a rapid diagnostic test and the McIsaac score for patient management in this setting and to determine the occurrence of emm genotypes among a subset of GAS isolated from children with acute pharyngotonsillitis and a history of acute rheumatic fever (ARF) or rheumatic heart disease (RHD). Group A beta-haemolytic streptococcus infections in school-aged children with acute pharyngotonsillitis in Aden, Yemen, were diagnosed by a rapid GAS antigen detection test (RADT) and/or GAS culture from a throat swab. The RADT value and the McIsaac screening score for patient management were evaluated. The emm genotype of a subset of GAS isolates was determined. Group A beta-haemolytic streptococcus pharyngotonsillitis was diagnosed in 287/691 (41.5%; 95% CI 37.8-45.3) children. Group B, Group C and Group G beta-haemolytic streptococci were isolated from 4.3% children. The RADT had a sensitivity of 238/258 (92.2%) and specificity of 404/423 (95.5%) against GAS culture. A McIsaac score of ≥4 had a sensitivity of 93% and a specificity of 82% for confirmed GAS infection. The emm genotypes in 21 GAS isolates from children with pharyngitis and a history of ARF and confirmed RHD were emm87 (11), emm12 (6), emm28 (3) and emm5 (1). This study demonstrates a very high prevalence of GAS infections in Yemeni children and the value of the RADT and the McIsaac score in this setting. More extensive emm genotyping is necessary to understand the local epidemiology of circulating strains. © 2014 John Wiley & Sons Ltd.

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

Science.gov (United States)

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

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.

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.

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.

Rhesus (Rh) D antigen is the most important antigen in the Rh blood group system because of its strong immunogenicity. When RhD-negative individuals are exposed to RhD-positive blood, they may produce anti-D alloantibody, potentially resulting in delayed haemolytic transfusion reactions and Rh haemolytic disease of the foetus and newborn, which are difficult to treat. Inhibition of the binding of anti-D antibody with RhD antigens on the surface of red blood cells may effectively prevent immune haemolytic diseases. In this study, single-stranded (ss) DNA aptamers, specifically binding to anti-D antibodies, were selected via systematic evolution of ligands by exponential enrichment (SELEX) technology. After 14 rounds of selection, the purified ssDNA was sequenced using a Personal Genome Machine system. Haemagglutination inhibition assays were performed to screen aptamers for biological activity in terms of blocking antigen-antibody reactions: the affinity and specificity of the aptamers were also determined. In addition to high specificity, the aptamers which were selected showed high affinity for anti-D antibodies with dissociation constant (K d ) values ranging from 51.46±14.90 to 543.30±92.59 nM. By the combined use of specific ssDNA aptamer 7 and auxiliary ssDNA aptamer 2, anti-D could be effectively neutralised at low concentrations of the aptamers. Our results demonstrate that ssDNA aptamers may be a novel, promising strategy for the treatment of delayed haemolytic transfusion reactions and Rh haemolytic disease of the foetus and newborn.

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.

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.

We have reviewed the records of all patients referred to our departments with aplastic anaemia during the 11 years from 1979 to 1989. Of the 22 patients identified, 19 fulfilled the standard criteria for severe aplastic anaemia. There were 11 females and 11 males. Their mean age was 35 (range 2-85 years). Five cases followed exposure to drugs known to cause aplastic anaemia and one had a recent history of viral hepatitis. A variety of treatments were used. Four patients received an allogeneic bone marrow transplant (BMT) from matched sibling donors and two of these were alive and well 65 and 120 months post BMT. Antithymocyte globulin (ATG) treatment has been followed by lasting complete remission in two of the six patients treated and a partial response was seen in one other patient. Cyclosporin therapy was associated with unmaintained complete remission in one of the three patients given this drug after ATG had failed. The remaining 13 patients received only supportive care with or without androgens and six (46%) had early recovery of bone marrow function with lasting complete remission. These patients illustrate some of the therapeutic options available for aplastic anaemia.

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.

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.

Pathophysiological mechanisms of severe anaemia in Malawian children.

2010-09-01

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.

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.

Beyond anaemia management: evolving role of erythropoietin therapy in neurological disorders, multiple myeloma and tumour hypoxia models.

Boogaerts, Marc; Mittelman, Moshe; Vaupel, Peter

2005-01-01

Recombinant human erythropoietin (epoetin) has become the standard of care in the treatment of anaemia resulting from cancer and its treatment, and chronic kidney disease. The discovery that erythropoietin and its receptor are located in regions outside the erythropoietic system has led to interest in the potential role of epoetin in other tissues, such as the central nervous system. Animal studies have shown that systemically applied epoetin can cross the blood-brain barrier, where it reduces tissue injury associated with stroke, blunt trauma and experimental autoimmune encephalomyelitis. Pilot studies in humans have shown that epoetin treatment given within 8 h of stroke reduces infarct size and results in a significantly better outcome when compared with placebo treatment. Studies also suggest that epoetin has the potential to improve cognitive impairment associated with adjuvant chemotherapy in patients with cancer. Anaemia is a major factor causing tumour hypoxia, a condition that can promote changes within neoplastic cells that further tumour survival and malignant progression and also reduces the effectiveness of several anticancer therapies including radiotherapy and oxygen-dependent cytotoxic agents. Use of epoetin to prevent or correct anaemia has the potential to reduce tumour hypoxia and improve treatment outcome. Several therapeutic studies in anaemic animals with experimental tumours have shown a beneficial effect of epoetin on delaying tumour growth. Furthermore, clinical observations in patients with multiple myeloma and animal studies have suggested that epoetin has an antimyeloma effect, mediated via the immune system through activation of CD8+ T cells. Therefore, the role of epoetin may go well beyond that of increasing haemoglobin levels in anaemic patients, although additional studies are required to confirm these promising results.

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

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.

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.

A case of a 15-year-old female patient with acute heart failure due to non-compaction cardiomyopathy and hereditary anaemia (hereditary spherocytic elliptocytosis) requiring ventricular assist device implantation as a bridge to transplantation is presented. The possible effects of mechanical stress on erythrocytes potentially induced by mechanical circulatory support remains unclear, but it may lead to haemolytic crisis in patients suffering from hereditary anaemia. In our case, ventricular assist device therapy was feasible, and haematological complications did not occur within 6 weeks of bridging our patient to heart transplantation.

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.

In infants under 3 years of age acquired primary hypothyroidism caused by autoimmune thyroiditis is very rare. Hypothyroidism can manifest with different signs and symptoms and has a wide range of presentations from subclinical hypothyroidism to overt form. We describe a child with acquired autoimmune thyroiditis during a very early period of life and with a severe hypothyroidism presentation. A 22-month-old white male patient with normal neonatal screening presented with a six-month history of asthenia and cutaneous pallor. At general clinical and biochemical exams he showed weight gain, statural growth deceleration, poor movements, sleepy expression, instability while walking, myxoedema, bradycardia, open anterior fontanelle, changes in the face habitus, macrocytic anaemia, ascites, and high CPK, creatinine and cholesterol levels. Acquired autoimmune thyroiditis was the final diagnosis. The thyroxine replacement therapy normalized all the clinical and biochemical abnormalities but at the age of 30 months his mental age showed a delay of 6 months. Our case could give useful learning points: i) although the screening for congenital hypothyroidism is routinely performed, a severe hypothyroidism (for example due to autoimmune thyroiditis) can anyway occur early in life and the clinicians should consider this possibility; ii) hypothyroidism can have a misleading and multi-face clinical presentation; iii) anemia, rhabdomyolysis and high creatinine levels should always include the hypothyroidism in the differential diagnosis; iv) thyroxine replacement therapy is able to revert all the clinical manifestations related to the hypothyroidism; v) evaluating the patient's previous pictures could play an important role in resolving a diagnostic conundrum.

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

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 pa...

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.

Gwinyai Masukume

Full Text Available 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 < 11g/dL. Binary logistic regression with adjustment for potential confounders (country, maternal age, having a marital partner, ethnic origin, years of schooling, and having paid work was the main method of analysis.The hallmark findings were the low 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 < 7 at one and five minutes. Adverse 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.

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.

CD8+ T-Cell Deficiency, Epstein-Barr Virus Infection, Vitamin D Deficiency, and Steps to Autoimmunity: A Unifying Hypothesis

Directory of Open Access Journals (Sweden)

Michael P. Pender

2012-01-01

Full Text Available CD8+ T-cell deficiency is a feature of many chronic autoimmune diseases, including multiple sclerosis, rheumatoid arthritis, systemic lupus erythematosus, Sjögren's syndrome, systemic sclerosis, dermatomyositis, primary biliary cirrhosis, primary sclerosing cholangitis, ulcerative colitis, Crohn's disease, psoriasis, vitiligo, bullous pemphigoid, alopecia areata, idiopathic dilated cardiomyopathy, type 1 diabetes mellitus, Graves' disease, Hashimoto's thyroiditis, myasthenia gravis, IgA nephropathy, membranous nephropathy, and pernicious anaemia. It also occurs in healthy blood relatives of patients with autoimmune diseases, suggesting it is genetically determined. Here it is proposed that this CD8+ T-cell deficiency underlies the development of chronic autoimmune diseases by impairing CD8+ T-cell control of Epstein-Barr virus (EBV infection, with the result that EBV-infected autoreactive B cells accumulate in the target organ where they produce pathogenic autoantibodies and provide costimulatory survival signals to autoreactive T cells which would otherwise die in the target organ by activation-induced apoptosis. Autoimmunity is postulated to evolve in the following steps: (1 CD8+ T-cell deficiency, (2 primary EBV infection, (3 decreased CD8+ T-cell control of EBV, (4 increased EBV load and increased anti-EBV antibodies, (5 EBV infection in the target organ, (6 clonal expansion of EBV-infected autoreactive B cells in the target organ, (7 infiltration of autoreactive T cells into the target organ, and (8 development of ectopic lymphoid follicles in the target organ. It is also proposed that deprivation of sunlight and vitamin D at higher latitudes facilitates the development of autoimmune diseases by aggravating the CD8+ T-cell deficiency and thereby further impairing control of EBV. The hypothesis makes predictions which can be tested, including the prevention and successful treatment of chronic autoimmune diseases by controlling EBV infection.

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.

A STUDY OF MORPHOLOGICAL TYPES OF ANAEMIA IN A TERTIARY CARE HOSPITAL - A TWO-YEAR STUDY

Directory of Open Access Journals (Sweden)

Kiran Kumar Epari

2016-08-01

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.

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.

Iron deficiency anaemia -a risk factor for febrile seizures in children

International Nuclear Information System (INIS)

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)

Medical research with radioisotopes in Greece

An important program of research into the nature and causes of congenital haemolytic anaemias, notably the disease known as Mediterranean anaemia or Thalassaemia, which is a serious medical problem in the Mediterranean countries, is at present being carried out in the Department of Clinical Therapeutics of the University of Athens under a research contract awarded by the International Atomic Energy Agency. This program is concerned with diseases in which there is an inherited defect or abnormality in the production of haemoglobin, the iron-containing pigment of the red blood cells which is responsible for the carriage of oxygen in the blood. Two techniques have been widely used in the studies at the University of Athens. In the first of these, a radioisotope of iron, iron-59, is used to follow iron metabolism and haemoglobin production. Iron metabolism in the body is concerned largely with the synthesis and breakdown of haemoglobin, which consists of a protein, globin, linked to an iron containing substance, haeme. The second technique makes use of a radioisotope of chromium, chromium-51, to study the fate of the red cells in the blood. By performing simultaneous studies with iron- 59 and chromium-51, a detailed picture of haemoglobin synthesis and red cell production and destruction can be built up. Such investigations have been invaluable in establishing the characteristic patterns of different congenital haemolytic anaemias.

This study was carried out to determine the prevalence of anaemia at booking clinic, describe the antenatal booking pattern, and categorize the degree of anaemia with certain demographic features. This is a descriptive cross-sectional study carried out over a six month period between 1st April and 30th September 2008. A questionnaire was used to obtain demographic information and venous blood samples were collected from 1,086 consecutive patients who consented to participate in the study. The blood samples were tested for haemoglobin levels, genotype and blood group. Seven hundred and thirty two (67.4%) of the women anaemic at booking. Anaemia was more prevalent among multgravidae than primigravidae (panaemia while 40(4.4%) had moderate anaemia and 15 (1.4%) were severely anaemic, of which 8 (53.3%) were below 18 years of age. Varied degrees of anaemia were more common among women aged 24-28 years and in the 3rd trimester of pregnancy (80.7%) (ppregnancies. Thirteen (1.2%) had sickle cell anaemia. Prevalence of anaemia at booking remains high in our society. Urgent need for public health education on early antenatal booking and improved literacy level of women is suggested to reduce the burden of anaemia in pregnancy.

Porphyromonas gingivalis is an obligately anaerobic bacterium recognized as an aetiological agent of adult periodontitis. P. gingivalis produces cysteine proteinases, the gingipains. The crystal structure of a domain within the haemagglutinin region of the lysine gingipain (Kgp) is reported here. The domain was named K2 as it is the second of three homologous structural modules in Kgp. The K2 domain structure is a 'jelly-roll' fold with two anti-parallel {beta}-sheets. This fold topology is shared with adhesive domains from functionally diverse receptors such as MAM domains, ephrin receptor ligand binding domains and a number of carbohydrate binding modules. Possible functions of K2 were investigated. K2 induced haemolysis of erythrocytes in a dose-dependent manner that was augmented by the blocking of anion transport. Further, cysteine-activated arginine gingipain RgpB, which degrades glycophorin A, sensitized erythrocytes to the haemolytic effect of K2. Cleaved K2, similar to that found in extracted Kgp, lacks the haemolytic activity indicating that autolysis of Kgp may be a staged process which is artificially enhanced by extraction of the protein. The data indicate a functional role for K2 in the integrated capacity conferred by Kgp to enable the porphyrin auxotroph P. gingivalis to capture essential haem from erythrocytes.

Background: Heart Failure (HF) is a common disease with a high mortality rate. Anaemia and renal failure (RF) are often present in patients with HF and associated with worse prognosis. Objective of study was to evaluate the prevalence of anaemia and RF in patients with HF. Methods: Patients admitted in Punjab institute of cardiology Lahore with diagnosis of heart failure were enrolled from February, 2008 to December, 2008. Anaemia was defined as haemoglobin levels <13 mg/dl for men and 12 mg/dl for women. Renal function was assessed by the glomerular filtration rate (GFR), calculated by the simplified formula of the MDRD (Modification of Diet in Renal Disease) study. Results : Of the 276 patients included in this study, 42.03% (116) had anaemia and 38.40% (106) had moderate to severe renal failure (GFR <60 ml/min). Conclusion: The prevalence of anaemia and renal failure was high in this population and was associated with the severity of the HF (functional classes III and IV). (author)

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.

Autoimmune diseases (ADs) represent a heterogeneous group of disorders that affect specific target organs or multiple organ systems. These conditions share common immunopathogenic mechanisms (i.e., the autoimmune tautology), which explain the clinical similarities they have among them as well as their familial clustering (i.e., coaggregation). As part of the autoimmune tautology, the influence of environmental exposure on the risk of developing ADs is paramount (i.e., the autoimmune ecology). In fact, environment, more than genetics, shapes immune system. Autoimmune ecology is akin to exposome, that is all the exposures - internal and external - across the lifespan, interacting with hereditary factors (both genetics and epigenetics) to favor or protect against autoimmunity and its outcomes. Herein, we provide an overview of the autoimmune ecology, focusing on the immune response to environmental agents in general, and microbiota, cigarette smoking, alcohol and coffee consumption, socioeconomic status (SES), gender and sex hormones, vitamin D, organic solvents, and vaccines in particular. Inclusion of the autoimmune ecology in disease etiology and health will improve the way personalized medicine is currently conceived and applied.

Galectin-3 (gal-3) is a β-galactoside-binding lectin, which regulates cell-cell and extracellular interactions during self/non-self-antigen recognition and cellular activation, proliferation, differentiation, migration and apoptosis. It plays a significant role in cellular and tissue pathophysiology by organizing niches that drive inflammation and immune responses. Gal-3 has some therapeutic potential in several diseases, including chronic inflammatory disorders, cancer and autoimmune diseases. Gal-3 exerts a broad spectrum of functions which differs according to its intra- or extracellular localization. Recombinant gal-3 strategy has been used to identify potential mode of action of gal-3; however, exogenous gal-3 may not reproduce the functions of the endogenous gal-3. Notably, gal-3 induces monocyte-macrophage differentiation, interferes with dendritic cell fate decision, regulates apoptosis on T lymphocytes and inhibits B-lymphocyte differentiation into immunoglobulin secreting plasma cells. Considering the influence of these cell populations in the pathogenesis of several autoimmune diseases, gal-3 seems to play a role in development of autoimmunity. Gal-3 has been suggested as a potential therapeutic agent in patients affected with some autoimmune disorders. However, the precise role of gal-3 in driving the inflammatory process in autoimmune or immune-mediated disorders remains elusive. Here, we reviewed the involvement of gal-3 in cellular and tissue events during autoimmune and immune-mediated inflammatory diseases. © 2015 by the Society for Experimental Biology and Medicine.

Anaemia and pregnancy: Anaesthetic implications

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.

Cationic peptides proved fundamental importance as pharmaceutical agents and/or drug carrier moieties functioning in cellular processes. The comparison of the in vitro activity of these peptides is an experimental challenge and a combination of different methods, such as cytotoxicity, internalisation rate, haemolytic and antibacterial effect, is necessary. At the same time, several issues need to be addressed as the assay conditions have a great influence on the measured biological effects and the experimental setup needs to be optimised. Therefore, critical comparison of results from different assays using representative examples of cell penetrating and antimicrobial peptides was performed and optimal test conditions were suggested. Our main goal was to identify carrier peptides for drug delivery systems of antimicrobial drug candidates. Based on the results of internalisation, haemolytic, cytotoxic and antibacterial activity assays, a classification of cationic peptides is advocated. We found eight promising carrier peptides with good penetration ability of which Penetratin, Tat, Buforin and Dhvar4 peptides showed low adverse haemolytic effect. Penetratin, Transportan, Dhvar4 and the hybrid CM15 peptide had the most potent antibacterial activity on Streptococcus pneumoniae (MIC lower than 1.2 μM) and Transportan was effective against Mycobacterium tuberculosis as well. The most selective peptide was the Penetratin, where the effective antimicrobial concentration on pneumococcus was more than 250 times lower than the HC 50 value. Therefore, these peptides and their analogues will be further investigated as drug delivery systems for antimicrobial agents.

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.

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.

Autoimmune pancreatitis

Full Text Available Background: Autoimmune pancreatitis is a recently described type of pancreatitis of presumed autoimmune etiology. Autoimmune pancreatitis is often misdiagnosed as pancreatic cancer difficult, since their clinical presentations are often similar. The concept of autoimmune pancreatitis was first published in 1961. Since then, autoimmune pancreatitis has often been treated not as an independent clinical entity but rather as a manifestation of systemic disease. The overall prevalence and incidence of the disease have yet to be determined, but three series have reported the prevalence as between 5 and 6 % of all patients with chronic pancreatitis. Patient vary widely in age, but most are older than 50 years. Patients with autoimmune pancreatitis usually complain of the painless jaundice, mild abdominal pain and weight loss. There is no laboratory hallmark of the disease, even if cholestatic profiles of liver dysfunction with only mild elevation of amylase and lipase levels have been reported.Conclusions: Proposed diagnostic criteria contains: (1 radiologic imaging, diffuse enlargement of the pancreas and diffusely irregular narrowing of the main pancreatic duct, (2 laboratory data, elevated levels of serum ã-globulin and/or IgG, specially IgG4, or the presence of autoantibodies and (3 histopathologic examination, fibrotic change with dense lymphoplasmacytic infiltration in the pancreas. For correct diagnosis of autoimmune pancreatitis, criterion 1 must be present with criterion 2 and/or 3. Autoimmune pancreatitis is frequently associated with rheumatoid arthritis, Sjogren’s syndrome, inflammatory bowel disease, tubulointersticial nephritis, primary sclerosing cholangitis and idiopathic retroperitoneal fibrosis. Pancreatic biopsy using an endoscopic ultrasound-guided fine needle aspiration biopsy is the most important diagnostic method today. Treatment with corticosteroids leads to the and resolution of pancreatic inflamation, obstruction and

The aim of the study was to identify beta-haemolytic streptococci in the vagina of bitches who had delivered healthy litters and bitches who had delivered litters in which neonatal deaths occurred. Fifty-one bitches divided into two groups were used. Group 1 (G1) included 28 bitches that had delivered healthy litters and group 2 (G2) included 23 bitches that had delivered puppies who died in the neonatal period. Two vaginal samples were taken, one in proestrus and the other at the end of gestation (EG). Beta-haemolytic Streptococcus (BS) was isolated from 16 bitches (57%) in G1 and from 21 bitches (91%) in G2. The bacteriological cultures, serological tests (Streptex ® ) and PCR assay allowed identification of Streptococcus canis and Streptococcus dysgalactiae in G1 and G2. Ultramicroscopic studies allowed the observation of M Protein and capsules in strains of S. dysgalactiae and S. canis in G1 and G2. The S. canis strains isolated from G2 showed thicker capsules than S. canis strains isolated from G1 (234 ± 24.2 vs 151.23 ± 28.93 nm; p  .70). All strains of beta-haemolytic Streptococcus isolated were penicillin sensitive. Penicillin was administered from EG to 5 days post-partum in 10 G2 females with isolation of BS (G2A). Saline solution was administered in eleven G2 females with isolation of BS (G2B). Ninety per cent of the puppies survived in G2A and 25% survived in G2B. Our results suggest BS is involved in canine neonatal deaths. © 2018 Blackwell Verlag GmbH.

Fanconi anaemia and the repair of Watson and Crick DNA crosslinks.

Kottemann, Molly C; Smogorzewska, Agata

2013-01-17

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.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the commonest human enzyme defect causing haemolytic anaemia after exposure to specific triggers. Paracetamol-induced haemolysis in G6PD deficiency is a rare complication and mostly reported in children. We report the first case (to the best of our knowledge) of acute jaundice without overt clinical features of a haemolytic crisis, in an otherwise healthy adult female following paracetamol overdose, due to previously undiagnosed G6PD deficiency. It is important that clinicians consider this condition when a patient presents following a paracetamol overdose with significant and disproportionate jaundice, without transaminitis or coagulopathy. © 2014 John Wiley & Sons A/S.

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

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.

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

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.

Alterations in the immune response of patients with autoimmune diseases may predispose to malignancies, and a link between chronic autoimmune gastritis and gastric cancer has been reported in many studies. Intestinal metaplasia with dysplasia of the gastric corpus-fundus mucosa and hyperplasia of chromaffin cells, which are typical features of late-stage autoimmune gastritis, are considered precursor lesions. Autoimmune gastritis has been associated with the development of two types of gastric neoplasms: intestinal type and type I gastric carcinoid. Here, we review the association of autoimmune gastritis with gastric cancer and other autoimmune features present in gastric neoplasms. PMID:29373557

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.

Congenital malaria with atypical presentation: A case report from low transmission area in India

Biswas Sukla

2007-04-01

Full Text Available Abstract Background Malaria during first few months of life may be due to transplacental transfer of parasitized maternal erythrocytes. Although IgG and IgM antimalarial antibodies can be detected in maternal blood, only IgG antibodies are present in the infant's blood. These antibodies can delay and modify the onset of clinical manifestations. Case Presentation An infant is described who presented with irritability and feeding problems. Clinical examination and investigations revealed that the infant was afebrile, had jaundice, hepatosplenomegaly and haemolytic anaemia. Peripheral smear demonstrated Plasmodium vivax. While the mother had significant levels of immunoglobulin G (IgG, the infant was found negative for IgG and had low immunoglobulin M (IgM levels. The mother had a history of febrile illness during pregnancy and her peripheral smear was also positive for P. vivax. Both were successfully treated with chloroquine in the dose of 25 mg/kg/day over three days. Conclusion The case emphasizes the importance of considering the diagnosis of malaria even in infants in low transmission area, who may not present with typical symptoms of malaria, such as fever, but have other clinical manifestations like jaundice and haemolytic 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.

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.

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.

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.

Update in endocrine autoimmunity.

Science.gov (United States)

Anderson, Mark S

2008-10-01

The endocrine system is a common target in pathogenic autoimmune responses, and there has been recent progress in our understanding, diagnosis, and treatment of autoimmune endocrine diseases. Rapid progress has recently been made in our understanding of the genetic factors involved in endocrine autoimmune diseases. Studies on monogenic autoimmune diseases that include endocrine phenotypes like autoimmune polyglandular syndrome type 1 and immune dysregulation, polyendocrinopathy, enteropathy, X-linked have helped reveal the role of key regulators in the maintenance of immune tolerance. Highly powered genetic studies have found and confirmed many new genes outside of the established role of the human leukocyte antigen locus with these diseases, and indicate an essential role of immune response pathways in these diseases. Progress has also been made in identifying new autoantigens and the development of new animal models for the study of endocrine autoimmunity. Finally, although hormone replacement therapy is still likely to be a mainstay of treatment in these disorders, there are new agents being tested for potentially treating and reversing the underlying autoimmune process. Although autoimmune endocrine disorders are complex in etiology, these recent advances should help contribute to improved outcomes for patients with, or at risk for, these disorders.

The adaptive response of mouse tumours to anaemia and retransfusion

International Nuclear Information System (INIS)

Hirst, D.G.; Wood, P.J.

1987-01-01

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.

BACKGROUND: There are a paucity of data on epistaxis as it pertains to sickle cell anaemia. Some case studies suggest epistaxis to be a significant complication in patients with sickle cell anaemia in sub-Saharan Africa; however, no robust studies have sought to establish the epidemiology...... or pathophysiology of this phenomenon. METHODS: We conducted a case-control study with the aim of investigating the importance of epistaxis among children presenting with sickle cell anaemia at the Mbale Regional Referral Hospital in eastern Uganda. Cases were children aged 2-15 years with an existing diagnosis...... of laboratory confirmed sickle cell anaemia, while controls were children without sickle cell anaemia who were frequency matched to cases on the basis of age group and gender.

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.

Autoimmune gastritis.

Autoimmune gastritis is a chronic inflammatory disease with destruction of parietal cells of the corpus and fundus of the stomach. The known consequence is vitamin B12 deficiency and, consequently, pernicious anemia. However, loss of parietal cells reduces secretion of gastric acid which is also required for absorption of inorganic iron; thus, iron deficiency is commonly found in patients with autoimmune gastritis. This usually precedes vitamin B12 deficiency and is found mainly in young women. Patients with chronic iron deficiency, especially those refractory to oral iron therapy, should therefore be evaluated for the presence of autoimmune gastritis.

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 12 . Results show no correlation between anaemia and age R(0.1048) p 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. Follow up and surveillance program to compact nutritional anaemia should be adopted.(Author)

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.

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.

Stress proteins, autoimmunity, and autoimmune disease.

Science.gov (United States)

Winfield, J B; Jarjour, W N

1991-01-01

At birth, the immune system is biased toward recognition of microbial antigens in order to protect the host from infection. Recent data suggest that an important initial line of defense in this regard involves autologous stress proteins, especially conserved peptides of hsp60, which are presented to T cells bearing gamma delta receptors by relatively nonpolymorphic class lb molecules. Natural antibodies may represent a parallel B cell mechanism. Through an evolving process of "physiological" autoreactivity and selection by immunodominant stress proteins common to all prokaryotes, B and T cell repertoires expand during life to meet the continuing challenge of infection. Because stress proteins of bacteria are homologous with stress proteins of the host, there exists in genetically susceptible individuals a constant risk of autoimmune disease due to failure of mechanisms for self-nonself discrimination. That stress proteins actually play a role in autoimmune processes is supported by a growing body of evidence which, collectively, suggests that autoreactivity in chronic inflammatory arthritis involves, at least initially, gamma delta cells which recognize epitopes of the stress protein hsp60. Alternate mechanisms for T cell stimulation by stress proteins undoubtedly also exist, e.g., molecular mimicry of the DR beta third hypervariable region susceptibility locus for rheumatoid arthritis by a DnaJ stress protein epitope in gram-negative bacteria. While there still is confusion with respect to the most relevant stress protein epitopes, a central role for stress proteins in the etiology of arthritis appears likely. Furthermore, insight derived from the work thus far in adjuvant-induced arthritis already is stimulating analyses of related phenomena in autoimmune diseases other than those involving joints. Only limited data are available in the area of humoral autoimmunity to stress proteins. Autoantibodies to a number of stress proteins have been identified in SLE and

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.

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.

Heart failure (HF) is a frequent cause of ospitalisation in cardiology. Its prognosis depends on several risk factors, one of which is anaemia. We aimed to determine the prevalence of anaemia in patients with heart failure, and evaluate its impact on their prognosis. This article describes a cross-sectional study with prospective collection of data, carried out from 1 January to 31 December 2010 in the Department of Cardiology at Brazzaville University Hospital, Congo. Patients admitted for heart failure were included. Anaemia was defined as a haemoglobin level failure, and it had a negative effect on the prognosis.

Haemoglobin, anaemia, dementia and cognitive decline in the elderly, a systematic review

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

Aplastic anaemia occurring in pregnancy is a rare event with life threatening challenges for both mother and child. We present a successful fetomaternal outcome despite the challenges in the management of this rare condition in a tertiary but resource poor centre. This is case of a 37 year old Nigerian woman G6P0 +5 managed with repeated blood transfusions from 28 weeks of gestation for bone marrow biopsy confirmed aplastic anaemia following presentation with weakness and gingival bleeds. She had a cesarean section at 37 weeks for pre-eclampsia and oligohydraminous with good feto-maternal outcome. She was managed entirely with fresh whole blood and received 21 units. Aplastic Anaemia in Pregnancy is a rare event with poor feto maternal prognosis. Successful management is possible with good multi-disciplinary approach and availability of supportive comprehensive obstetric care.

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.

Full Text Available Eosinophils are multifunctional granulocytes that contribute to initiation and modulation of inflammation. Their role in asthma and parasitic infections has long been recognized. Growing evidence now reveals a role for eosinophils in autoimmune diseases. In this review, we summarize the function of eosinophils in inflammatory bowel diseases, neuromyelitis optica, bullous pemphigoid, autoimmune myocarditis, primary biliary cirrhosis, eosinophilic granulomatosis with polyangiitis, and other autoimmune diseases. Clinical studies, eosinophil-targeted therapies, and experimental models have contributed to our understanding of the regulation and function of eosinophils in these diseases. By examining the role of eosinophils in autoimmune diseases of different organs, we can identify common pathogenic mechanisms. These include degranulation of cytotoxic granule proteins, induction of antibody-dependent cell-mediated cytotoxicity, release of proteases degrading extracellular matrix, immune modulation through cytokines, antigen presentation, and prothrombotic functions. The association of eosinophilic diseases with autoimmune diseases is also examined, showing a possible increase in autoimmune diseases in patients with eosinophilic esophagitis, hypereosinophilic syndrome, and non-allergic asthma. Finally, we summarize key future research needs.

2014-01-01

The term thyroiditis comprises a group of thyroid diseases characterized by the presence of inflammation, including autoimmune and non-autoimmune entities. It may manifest as an acute illness with severe thyroid pain (subacute thyroiditis and infectious thyroiditis), and conditions in which the inflammation is not clinically evident evolving without pain and presenting primarily thyroid dysfunction and/or goiter (drug-induced thyroiditis and Riedel thyroiditis). The aim of this review is to provide an updated approach on non-autoimmune thyroiditis and its clinical, diagnostic and therapeutic aspects.

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.

Hot topics in autoimmune diseases: perspectives from the 2013 Asian Congress of Autoimmunity.

Our understanding of the pathogenic mechanisms and possible treatments of autoimmune diseases has significantly increased over the past decade. Nonetheless, numerous major issues remain open and such issues span from epidemiology to clinimetrics and from the role of infectious agents to the search for accurate biomarkers in paradigmatic conditions such as systemic lupus erythematosus, rheumatoid arthritis, and spondyloarthropathies. In the case of cardiovascular comorbidities of autoimmune diseases or, more generally, the pathogenesis of atherosclerosis, fascinating evidence points to a central role of autoimmunity and metabolic dysfunctions and a possible role of therapies targeting inflammation to ameliorate both conditions. Basic science and translational medicine contribute to identify common mechanisms that underlie different autoimmune diseases, as in the case of tumor necrosis factor alpha, and more recently vitamin D, autoantibodies, T and B regulatory cells, and microRNA. Finally, new therapies are expected to significantly change our approach to autoimmune diseases, as represented by the recent FDA approval of the first oral JAK inhibitor. The present article moves from the major topics that were discussed at the 2013 Asian Congress of Autoimmunity in Hong Kong to illustrate the most recent data from leading journals in autoimmunity and immunology.

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.

Radioisotopes of iron in investigation of anaemia in malnutrition

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.

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.

Fanconi anaemia with bilateral diffuse pulmonary arterio venous fistulae: a case report

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.

Nonsegmental Vitiligo and Autoimmune Mechanism

Directory of Open Access Journals (Sweden)

Naoki Oiso

2011-01-01

Full Text Available Nonsegmental vitiligo is a depigmented skin disorder showing acquired, progressive, and depigmented lesions of the skin, mucosa, and hair. It is believed to be caused mainly by the autoimmune loss of melanocytes from the involved areas. It is frequently associated with other autoimmune diseases, particularly autoimmune thyroid diseases including Hashimoto's thyroiditis and Graves' disease, rheumatoid arthritis, type 1 diabetes, psoriasis, pernicious anemia, systemic lupus erythematosus, Addison's disease, and alopecia areata. This indicates the presence of genetically determined susceptibility to not only vitiligo but also to other autoimmune disorders. Here, we summarize current understanding of autoimmune pathogenesis in non-segmental vitiligo.

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.

Vaccines, adjuvants and autoimmunity.

Guimarães, Luísa Eça; Baker, Britain; Perricone, Carlo; Shoenfeld, Yehuda

2015-10-01

Vaccines and autoimmunity are linked fields. Vaccine efficacy is based on whether host immune response against an antigen can elicit a memory T-cell response over time. Although the described side effects thus far have been mostly transient and acute, vaccines are able to elicit the immune system towards an autoimmune reaction. The diagnosis of a definite autoimmune disease and the occurrence of fatal outcome post-vaccination have been less frequently reported. Since vaccines are given to previously healthy hosts, who may have never developed the disease had they not been immunized, adverse events should be carefully accessed and evaluated even if they represent a limited number of occurrences. In this review of the literature, there is evidence of vaccine-induced autoimmunity and adjuvant-induced autoimmunity in both experimental models as well as human patients. Adjuvants and infectious agents may exert their immune-enhancing effects through various functional activities, encompassed by the adjuvant effect. These mechanisms are shared by different conditions triggered by adjuvants leading to the autoimmune/inflammatory syndrome induced by adjuvants (ASIA syndrome). In conclusion, there are several case reports of autoimmune diseases following vaccines, however, due to the limited number of cases, the different classifications of symptoms and the long latency period of the diseases, every attempt for an epidemiological study has so far failed to deliver a connection. Despite this, efforts to unveil the connection between the triggering of the immune system by adjuvants and the development of autoimmune conditions should be undertaken. Vaccinomics is a field that may bring to light novel customized, personalized treatment approaches in the future. Copyright © 2015 Elsevier Ltd. All rights reserved.

Autoimmune liver disease and therapy in childhood

Directory of Open Access Journals (Sweden)

Matjaž Homan

2013-10-01

Full Text Available Autoimmune hepatitis is a chronic immune-mediated disease of the liver. In childhood, autoimmune liver disorders include autoimmune hepatitis type I and II, autoimmune sclerosing cholangitis, Coombs-positive giant cell hepatitis, and de novo autoimmune hepatitis after liver transplantation. Autoimmune liver disease has a more aggressive course in children, especially autoimmune hepatitis type II. Standard therapy is a combination of corticosteroids and azathioprine. Around 80 % of children with autoimmune liver disease show a rapid response to combination therapy. The non-responders are treated with more potent drugs, otherwise autoimmune disease progresses to cirrhosis of the liver and the child needs liver transplantation as rescue therapy.

Normal cellular radiosensitivity in an adult Fanconi anaemia patient with marked clinical radiosensitivity

International Nuclear Information System (INIS)

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

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

LENUS (Irish Health Repository)

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.

Cytokine Expression in Homozygous Sickle Cell Anaemia

2015-01-01

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

Previous research has suggested an inverse relationship between T-helper 2-related atopic disorders, such as asthma, and T-helper 1-related autoimmune diseases. One controversial hypothesis postulates that asthma provides a protective effect for the development of autoimmune-related disorders. To assess the rate of newly diagnosed autoimmune disorders in a large cohort of young adults. Using cross-sectional data from the Israeli Defense Force database, the authors analyzed the prevalence of autoimmune disorders in asthmatic and nonasthmatic military personnel between 1980 and 2003. A follow-up study traced newly diagnosed autoimmune disorders among asthmatic and nonasthmatic individuals from the time of enrollment in military service until discharge (22 and 36 months for women and men, respectively). General community. 307,367 male and 181,474 female soldiers in compulsory military service who were between 18 and 21 years of age. Cases of type 1 diabetes mellitus, vasculitis, immune thrombocytopenic purpura, inflammatory bowel disease, rheumatoid arthritis, and the antiphospholipid syndrome. Of 488,841 participants at enrollment, significantly more women than men had autoimmune disorders. Compared with asthmatic women, nonasthmatic women had a significantly higher prevalence of all autoimmune disorders except for the antiphospholipid syndrome. Type 1 diabetes mellitus, vasculitis, and rheumatoid arthritis were less prevalent in men with asthma than in those without. During the follow-up period, vasculitis and rheumatoid arthritis were more frequently diagnosed in nonasthmatic persons of both sexes. There was a significantly higher incidence of immune thrombocytopenic purpura, inflammatory bowel disease, and the antiphospholipid syndrome in nonasthmatic women and a statistically significantly higher incidence of type 1 diabetes mellitus in nonasthmatic men. The study was limited to a population of young military recruits; therefore, its findings are not necessarily

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.

In children after haemolytic-uraemic syndrome (HUS), little is known about long-term health-related quality of life (HRQoL) and psychological adjustment as defined by behavioural problems, depressive symptoms and post-traumatic stress symptoms. Sixty-two paediatric patients with a history of HUS were included in this study. Medical data of the acute HUS episode were retrieved retrospectively from hospital records. Data on the clinical course at study investigation were assessed by clinical examination and laboratory evaluation. HRQoL and psychological adjustment data were measured by standardised, parent- and self-reported questionnaires. Haemolytic-uraemic syndrome was diagnosed at a mean of 6.5 years before the initiation of the study (standard deviation 2.9, range 0.1-15.7) years. Among the preschool children, parents reported that their child was less lively and energetic (HRQoL emotional dimension), while no increased behavioural problems were reported. In the school-age children, self- and proxy-reported HRQoL was well within or even above the norms, while increased total behavioural problems were found. The school-age children reported no increased depression scores. Also none of the children met the criteria for full or partial HUS-associated posttraumatic stress disorder. Healthcare providers should be particularly alert to behavioural problems in school-age children with a history of HUS and to lower HRQoL in preschool children.

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.

[Stress and auto-immunity].

The etiology of auto-immune disorders is multifactorial. Stress is probably a participating factor. Indeed, a high proportion of patients with auto-immune diseases report uncommon stress before disease onset or disease flare. The biological consequences of stress are increasingly well understood. Glucocorticoids and catecholamines released by hypothalamic-pituitary-adrenal axis during stress will alter the balance Th1/Th2 and the balance Th17/Treg. Stress impairs cellular immunity, decreases immune tolerance and stimulates humoral immunity exposing individuals to autoimmune disease among others. The treatment for autoimmune disease should include stress management. Copyright © 2012 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS. All rights reserved.

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.

Iron overload caused by blood transfusion-dependent anaemia usually results in lethal cardiac toxicity unless treated by iron-chelation therapy. Chelation therapy with desferrioxamine (DFO) is well established and widely used to remove excess iron. Unfortunately, visual disorders have been recorded after DFO infusion. In this investigation, a 61-year-old Caucasian female received DFO for her autoimmune haemolytic anaemia. Prior to starting with the DFO treatment, her baseline ophthalmic screening and electrooculogram (EOG) were completely normal. Two years later she noticed a grey scotoma in her right eye. Visual acuity in this eye was reduced from 6/5 to 6/9 and funduscopy revealed evidence of non-specific mottling of the retinal pigment epithelium of both retinae. The EOG was flat (106%) in the right eye and subnormal in the left (155%). The lower limit of our EOG Arden Ratio for normal subjects is 180%. After her DFO treatment was stopped, her right visual acuity returned to 6/5, her field tests showed progressive improvement bilaterally and the EOG went back to the normal range. While waiting for splenectomy, the patient was restarted on a lower dose of DFO and EOG measurements were carried out every two (or three) weeks to monitor for DFO toxicity. The EOG varied during this period indicating some deterioration of function in the retinal pigment epithelium. However, normalisation of the EOG values (right = 217%, left = 217%) occurred after splenectomy and cessation of DFO therapy. Her visual function was normal and her visual acuity 6/4 bilateral when she was discharged from our outpatient clinic. On reviewing her history it was apparent that the EOG was the most sensitive indicator of DFO toxicity.

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.

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.

Western countries are seeing a constant decline in the incidence of Helicobacter pylori-associated gastritis, coupled with a rising epidemiological and clinical impact of autoimmune gastritis. This latter gastropathy is due to autoimmune aggression targeting parietal cells through a complex interaction of auto-antibodies against the parietal cell proton pump and intrinsic factor, and sensitized T cells. Given the specific target of this aggression, autoimmune gastritis is typically restricted to the gastric corpus-fundus mucosa. In advanced cases, the oxyntic epithelia are replaced by atrophic (and metaplastic) mucosa, creating the phenotypic background in which both gastric neuroendocrine tumors and (intestinal-type) adenocarcinomas may develop. Despite improvements in our understanding of the phenotypic changes or cascades occurring in this autoimmune setting, no reliable biomarkers are available for identifying patients at higher risk of developing a gastric neoplasm. The standardization of autoimmune gastritis histology reports and classifications in diagnostic practice is a prerequisite for implementing definitive secondary prevention strategies based on multidisciplinary diagnostic approaches integrating endoscopy, serology, histology and molecular profiling.

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

Endocrine autoimmune disease: genetics become complex.

The endocrine system is a frequent target in pathogenic autoimmune responses. Type 1 diabetes and autoimmune thyroid disease are the prevailing examples. When several diseases cluster together in one individual, the phenomenon is called autoimmune polyglandular syndrome. Progress has been made in understanding the genetic factors involved in endocrine autoimmune diseases. Studies on monogenic autoimmune diseases such as autoimmune polyglandular syndrome type 1, immunodysregulation, polyendocrinopathy, enteropathy, X-linked and primary immune deficiencies helped uncover the role of key regulators in the preservation of immune tolerance. Alleles of the major histocompatibility complex have been known to contribute to the susceptibility to most forms of autoimmunity for more than 3 decades. Furthermore, sequencing studies revealed three non-major histocompatibility complex loci and some disease specific loci, which control T lymphocyte activation or signalling. Recent genome-wide association studies (GWAS) have enabled acceleration in the identification of novel (non-HLA) loci and hence other relevant immune response pathways. Interestingly, several loci are shared between autoimmune diseases, and surprisingly some work in opposite direction. This means that the same allele which predisposes to a certain autoimmune disease can be protective in another. Well powered GWAS in type 1 diabetes has led to the uncovering of a significant number of risk variants with modest effect. These studies showed that the innate immune system may also play a role in addition to the adaptive immune system. It is anticipated that next generation sequencing techniques will uncover other (rare) variants. For other autoimmune disease (such as autoimmune thyroid disease) GWAS are clearly needed. © 2010 The Authors.

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.

Autoantibody detection for autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC) and autoimmune gastritis (AIG) is traditionally performed by IIF on a combination of tissues. Multiplex line/dot blots (LIA/DIA) offer multiple advantages, i.e. automation, objective reading, no interfering reactivities, no coincidental findings. In the current study we evaluated automated DIA (D-Tek) for detecting autoantibodies related to autoimmune diseases of the gastrointestinal tract. We tested samples of the Dutch EQC program and compared the results with the consensus of the participating labs. For the autoimmune liver diseases and AIG, respectively, 64 and 36 samples were tested. For anti-mitochondrial and anti-smooth muscle antibodies a concordance rate of 97% and 88% was observed, respectively. The concordance rate for anti-parietal cell antibodies was 92% when samples without EQC consensus (n=15) were excluded. For antibodies against intrinsic factor a concordance of 96% was observed. For all these antibodies discrepancies were identified that relate to the different test characteristics and the preponderance of IIF utilizing labs in the EQC program. In conclusion, we observed good agreement of the tested DIA blots with the consensus results of the Dutch EQC program. Taken together with the logistic advantages these blots are a good alternative for autoantibody detection in the respective diseases. A large prospective multicenter study is warranted to position these novel tests further in the whole spectrum of assays for the detection of these antibodies in a routine autoimmune laboratory.

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.

First described in the early 1980s, antiphospholipid syndrome (APS) is a unique form of acquired autoimmune thrombophilia in which patients present with clinical features of recurrent thrombosis and pregnancy morbidity and persistently test positive for the presence of antiphospholipid antibodies (aPL). At least one clinical (vascular thrombosis or pregnancy morbidity) and one lab-based (positive test result for lupus anticoagulant, anticardiolipin antibodies and/or anti-β2-glycoprotein 1 antibodies) criterion have to be met for a patient to be classified as having APS. However, the clinical spectrum of APS encompasses additional manifestations that can affect many organs and cannot be explained exclusively by patients being in a prothrombotic state; clinical manifestations not listed in the classification criteria (known as extra-criteria manifestations) include neurologic manifestations (chorea, myelitis and migraine), haematologic manifestations (thrombocytopenia and haemolytic anaemia), livedo reticularis, nephropathy and valvular heart disease. Increasingly, research interest has focused on the development of novel assays that might be more specific for APS than the current aPL tests. This Review focuses on the current classification criteria for APS, presenting the role of extra-criteria manifestations and lab-based tests. Diagnostic approaches to difficult cases, including so-called seronegative APS, are also discussed.

Full Text Available Background: Anaemia continues to be a severe public health nutritional problem in India affecting all physiological groups, even after the National Nutritional Anaemia Prophylaxis Programme has been in operation for more than three decades. 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.

2011-09-01

Full Text Available The occurrence of three or more autoimmune disorders in one patient defines multiple autoimmune syndrome. The pathogenesis of multiple autoimmune syndrome is not known yet and environmental triggers and genetic susceptibility have been suggested to be involved. Herein, we report a 47-year-old woman who had Hashimoto’s thyroiditis, vitiligo and newly diagnosed ulcerative colitis. Diagnosis of ulcerative colitis was confirmed with histopathologic examination. This case presents a new combination of multiple autoimmune syndrome.

Poša, Mihalj; Tepavčević, Vesna

2011-09-01

The formation of mixed micelles built of 7,12-dioxolithocholic and the following hydrophobic bile acids was examined by conductometric method: cholic (C), deoxycholic (D), chenodeoxycholic (CD), 12-oxolithocholic (12-oxoL), 7-oxolithocholic (7-oxoL), ursodeoxycholic (UD) and hiodeoxycholic (HD). Interaction parameter (β) in the studied binary mixed micelles had negative value, suggesting synergism between micelle building units. Based on β value, the hydrophobic bile acids formed two groups: group I (C, D and CD) and group II (12-oxoL, 7-oxoL, UD and HD). Bile acids from group II had more negative β values than bile acids from group I. Also, bile acids from group II formed intermolecular hydrogen bonds in aggregates with both smaller (2) and higher (4) aggregation numbers, according to the analysis of their stereochemical (conformational) structures and possible structures of mixed micelles built of these bile acids and 7,12-dioxolithocholic acid. Haemolytic potential and partition coefficient of nitrazepam were higher in mixed micelles built of the more hydrophobic bile acids (C, D, CD) and 7,12-dioxolithocholic acid than in micelles built only of 7,12-dioxolithocholic acid. On the other hand, these mixed micelles still had lower values of haemolytic potential than micelles built of C, D or CD. The mixed micelles that included bile acids: 12-oxoL, 7-oxoL, UD or HD did not significantly differ from the micelles of 7,12-dioxolithocholic acid, observing the values of their haemolytic potential.

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 detection of diagnostic autoantibodies such as antinuclear antibodies (ANA), anti-smooth muscle antibodies (SMA), anti-liver/kidney microsomal type 1 (anti-LKM1), anti-liver cytosol type 1 (anti-LC1) and anti-soluble liver antigen (anti-SLA) is historically associated with the diagnosis of autoimmune hepatitis. When autoimmune hepatitis is suspected, the detection of one or any combination of diagnostic autoantibodies, by indirect immunofluorescence or immuno-enzymatic techniques with recombinant antigens, is a pivotal step to reach a diagnostic score of probable or definite autoimmune hepatitis. Diagnostic autoantibodies (ANA, SMA, anti-LKM1, anti-LC1, anti-SLA) are a cornerstone in the diagnosis of autoimmune hepatitis. Other ancillary autoantibodies, associated with peculiar clinical correlations, appear to be assay-dependent and institution-specific, and validation studies are needed. © 2015 S. Karger AG, Basel.

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

Celiac disease and endocrine autoimmunity.

Science.gov (United States)

Kahaly, George J; Schuppan, Detlef

2015-01-01

Celiac disease (CD) is a small-intestinal inflammatory disease that is triggered by the ingestion of the storage proteins (gluten) of wheat, barley and rye. Endocrine autoimmunity is prevalent in patients with CD and their relatives. The genes that predispose to endocrine autoimmune diseases, e.g. type 1 diabetes, autoimmune thyroid diseases, and Addison's disease, i.e. DR3-DQ2 and DR4-DQ8, are also the major genetic determinants of CD, which is the best understood HLA-linked disease. Thus, up to 30% of first-degree relatives both of patients with CD and/or endocrine autoimmunity are affected by the other disease. In CD, certain gluten proteins bind with high affinity to HLA-DQ2 or -DQ8 in the small-intestinal mucosa, to activate gluten-specific T cells which are instrumental in the destruction of the resorptive villi. Here, the autoantigen tissue transglutaminase increases the T cell response by generating deamidated gluten peptides that bind more strongly to DQ2 or DQ8. Classical symptoms such as diarrhea and consequences of malabsorption like anemia and osteoporosis are often absent in patients with (screening-detected) CD, but this absence does not significantly affect these patients' incidence of endocrine autoimmunity. Moreover, once autoimmunity is established, a gluten-free diet is not able to induce remission. However, ongoing studies attempt to address how far a gluten-free diet may prevent or retard the development of CD and endocrine autoimmunity in children at risk. The close relationship between CD and endocrine autoimmunity warrants a broader immune genetic and endocrine screening of CD patients and their relatives. © 2015 S. Karger AG, Basel.

2010-11-01

The aim of this study was to estimate the frequency and severity of ocular involvement in paediatric patients with haemolytic uraemic syndrome (HUS). The study was designed as an institutional, retrospective, observational case series. Charts for all 87 paediatric patients with HUS treated at the University Children's Hospital Zurich between 1995 and 2007 were reviewed. Patients with ocular involvement were identified and clinical findings presented. Three of 69 examined patients with HUS showed ocular involvement. Ophthalmic findings in two children were consistent with bilateral Purtscher retinopathy, showing multiple haemorrhages, exudations and superficial retinal whitening. The third child presented with bilateral isolated central intraretinal haemorrhages as a milder form of ocular involvement. In one of the children with Purtscher retinopathy, laser photocoagulation was required for bilateral rubeosis irides and development of disc neovascularization. Longterm outcomes in the two severely affected children showed decreased visual acuity caused by partial atrophy of the optic nerves. In the milder case visual acuity was not impaired at any time. A minority of paediatric patients with HUS developed ocular involvement. Acute ocular findings varied in severity from isolated intraretinal haemorrhages to Purtscher-like retinopathy with retinal ischaemia. Longterm complications included the development of neovascularizations and consecutive optic nerve atrophy. Although ocular involvement in HUS seems to be rare, physicians should be aware of this complication because of its possible vision-endangering consequences. © 2009 The Authors.

Autoimmune hepatitis in association with lymphocytic colitis.

LENUS (Irish Health Repository)

Cronin, Edmond M

2012-02-03

Autoimmune hepatitis is a rare, chronic inflammatory disorder which has been associated with a number of other auto-immune conditions. However, there are no reports in the medical literature of an association with microscopic (lymphocytic) colitis. We report the case of a 53-year-old woman with several autoimmune conditions, including lymphocytic colitis, who presented with an acute hepatitis. On the basis of the clinical features, serology, and histopathology, we diagnosed autoimmune hepatitis. To our knowledge, this is the first report of autoimmune hepatitis in association with lymphocytic colitis, and lends support to the theory of an autoimmune etiology for lymphocytic colitis.

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.

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.

Phillips, Kate; Healy, Laura; Smith, Louise; Keenan, Russell

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.

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

International Nuclear Information System (INIS)

Ullah, K.; Satti, T.M.; Ahmed, P.; Raza, A.; Akhtar, F.M.; Tariq, W.U.Z.

2007-01-01

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

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.

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.

Type 3 autoimmune polyendocrine syndrome (APS-3) is defined by the presence of an autoimmune thyroid disease and another autoimmune illness, excluding Addison's disease; this is a frequent combination. We report the case of a 55 years old female patient with APS-3, with seven clinical or latent autoimmune manifestations. At 49 years of age she was admitted at the General Hospital for leukopenia, weight loss, tremors, anxiety and diarrhea. The personal history revealed ulcerative colitis and, during the last year, episodes of fever with migrant arthralgia and cutaneous lesions. The patient was evaluated for thyroid function and imaging, mielobiopsy, glycaemic control, gastrointestinal and rheumatologic disorders with specific biochemical tests, imaging and endoscopic procedures. We concluded that the patient was affected by APS-3, characterized by the association of Graves' disease, autoimmune leukopenia, latent autoimmune diabetes of the adult (LADA), autoimmune gastritis, ulcerative colitis, Sjögren's and anti-phospholipid syndromes. The patient started low doses of corticosteroid drugs for leukopenia, underwent (131)I therapy for hyperthyroidism and later started substitutive thyroid therapy with l-thyroxine, insulin therapy for LADA, mesalazine for ulcerative colitis and artificial tears for Sjögren's syndrome. In this article we report a complex case of APS-3, characterized by the association of seven different autoimmune diseases, which required a complex therapeutic strategy.

Liver disorders with a likely autoimmune pathogenesis in childhood include autoimmune hepatitis (AIH), autoimmune sclerosing cholangitis (ASC), and de novo AIH after liver transplantation. AIH is divided into two subtypes according to seropositivity for smooth muscle and/or antinuclear antibody (SMA/ANA, type 1) or liver kidney microsomal antibody (LKM1, type 2). There is a female predominance in both. LKM1 positive patients tend to present more acutely, at a younger age, and commonly have partial IgA deficiency, while duration of symptoms before diagnosis, clinical signs, family history of autoimmunity, presence of associated autoimmune disorders, response to treatment, and long-term prognosis are similar in both groups. The most common type of paediatric sclerosing cholangitis is ASC. The clinical, biochemical, immunological, and histological presentation of ASC is often indistinguishable from that of AIH type 1. In both, there are high IgG, non-organ specific autoantibodies, and interface hepatitis. Diagnosis is made by cholangiography. Children with ASC respond to immunosuppression satisfactorily and similarly to AIH in respect to remission and relapse rates, times to normalization of biochemical parameters, and decreased inflammatory activity on follow up liver biopsies. However, the cholangiopathy can progress. There may be evolution from AIH to ASC over the years, despite treatment. De novo AIH after liver transplantation affects patients not transplanted for autoimmune disorders and is strikingly reminiscent of classical AIH, including elevated titres of serum antibodies, hypergammaglobulinaemia, and histological findings of interface hepatitis, bridging fibrosis, and collapse. Like classical AIH, it responds to treatment with prednisolone and azathioprine. De novo AIH post liver transplantation may derive from interference by calcineurin inhibitors with the intrathymic physiological mechanisms of T-cell maturation and selection.

The immunosuppresive drugs, primarily glucocorticosteroids, serve as the basis for the pathogenetic treatment of autoimmune diseases of the liver. In autoimmune hepatitis, immunosuppressive therapy induces and maintains persistent remission in most patients while in primary biliary cirrhosis and primary sclerosing cholangitis, its capacities are substantially limited. Ursodeoxycholic acid is used as the basic drug in predominantly occurring intrahepatic cholestasis. The treatment of cross autoimmune syndromes generally requires the choice of a combination of drugs.

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

A 60-year-old woman was diagnosed with non-severe aplastic anaemia when she presented with anaemia and thrombocytopenia. She developed recurrent life-threatening hypotensive reactions during transfusion of leukodepleted platelet concentrates, and washed platelet concentrates prevented the development of such reactions subsequently. A paroxysmal nocturnal haemoglobinuria clone was detected on investigating for aplastic anaemia, which has been speculated to play a role in the recurrent hypotensive reactions. © 2014 The Authors; Internal Medicine Journal © 2014 Royal Australasian College of Physicians.

The role of the autoimmunity laboratory in autoimmune diseases

Directory of Open Access Journals (Sweden)

SS Hasson

2012-04-01

Full Text Available Laboratory testing is of great value when evaluating a patient with a suspected autoimmune disease. The results can confirm a diagnosis, estimate disease severity, aid in assessing prognosis and are useful to follow disease activity. Components of the laboratory exam include complete blood count with differential, comprehensive metabolic panel, inflammatory markers, autoantibodies, and flow cytometry. Currently, autoimmunity laboratories are very vibrant owing to the constant and increasing availability of new tests, mainly due to the detection of new autoantibodies. The main characteristic that differentiates the autoimmunity laboratory from other laboratories is the use of immunoassays such as enzyme-linked immunosorbent assay (ELISA, as basic techniques which determines antibodies (autoantibodies and not antigens. For this reason, immunoassay techniques must employ antigens as reagents. However, over the last few years, a significant trend at autoimmunity laboratories has been the gradual replacement of immunofluorescence microscopy by immunoassay. Nowadays the revolution of new technology has taken place significantly, for examples; recombinant DNA technology has allowed the production of large quantities of antigens for autoantibody analysis. Flow cytometry for the analysis of microsphere-based immunoassays allows the simultaneous measurement of several autoantibodies. In the same way, autoantigen microarrays provide a practical means to analyse biological fluids in the search for a high number of autoantibodies. We are now at the beginning of an era of multiplexed analysis, with a high capacity of autoantibody specificities. The future tendency in this field will include immunoassays with greater analytical sensitivity, specificity, simultaneous multiplexed capability, the use of protein microarrays, and the use of other technologies such as microfluidics.

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.

Autoimmune Cytopenias In Common Variable Immunodeficiency (CVID

Directory of Open Access Journals (Sweden)

Roshini Sarah Abraham

2012-07-01

Full Text Available Common variable immunodeficiency (CVID is a humoral immunodeficiency whose primary diagnostic features include hypogammaglobulinemia involving two or more immunoglobulin isotypes and impaired functional antibody responses in the majority of patients. While increased susceptibility to respiratory and other infections is a common thread that binds a large cross-section of CVID patients, the presence of autoimmune complications in this immunologically and clinically heterogeneous disorder is recognized in up to two-thirds of patients. Among the autoimmune manifestations reported in CVID (20-50%(Chapel et al., 2008;Cunningham-Rundles, 2008, autoimmune cytopenias are by far the most common occurring variably in 4-20% (Michel et al., 2004;Chapel et al., 2008 of these patients who have some form of autoimmunity. Association of autoimmune cytopenias with granulomatous disease and splenomegaly has been reported. The spectrum of autoimmune cytopenias includes thrombocytopenia, anemia and neutropenia. While it may seem paradoxical prima facie that autoimmunity is present in patients with primary immune deficiencies, in reality, it could be considered two sides of the same coin, each reflecting a different but inter-connected facet of immune dysregulation. The expansion of CD21low B cells in CVID patients with autoimmune cytopenias and other autoimmune features has also been previously reported. It has been demonstrated that this unique subset of B cells is enriched for autoreactive germline antibodies. Further, a correlation has been observed between various B cell subsets, such as class-switched memory B cells and plasmablasts, and autoimmunity in CVID. This review attempts to explore the most recent concepts and highlights, along with treatment of autoimmune hematological manifestations of CVID.

2013-01-01

Type 2 autoimmune polyendocrine syndromes (APS-2) are the most frequent disorders associating several organ-specific autoimmune diseases. Their high prevalence is due to the fact that the main manifestations of APS-2, such as thyroidal autoimmunity, type 1 diabetes, autoimmune gastric atrophy and vitiligo, are common diseases. APS-2 represents a clinical model that can serve to help unravel the mechanisms underlying autoimmunity. Diagnosis of APS-2 is a challenge for the clinician, especially in poorly symptomatic forms, and may require systematic screening based on measurement of autoantibodies and functional markers.

Helicobacter pylori (H. pylori) is the main cause of chronic gastritis and a major risk factor for gastric cancer. This pathogen has also been considered a potential trigger of gastric autoimmunity, and in particular of autoimmune gastritis. However, a considerable number of reports have attempted to link H. pylori infection with the development of extra-gastrointestinal autoimmune disorders, affecting organs not immediately relevant to the stomach. This review discusses the current evidence in support or against the role of H. pylori as a potential trigger of autoimmune rheumatic and skin diseases, as well as organ specific autoimmune diseases. We discuss epidemiological, serological, immunological and experimental evidence associating this pathogen with autoimmune diseases. Although over one hundred autoimmune diseases have been investigated in relation to H. pylori, we discuss a select number of papers with a larger literature base, and include Sjögrens syndrome, rheumatoid arthritis, systemic lupus erythematosus, vasculitides, autoimmune skin conditions, idiopathic thrombocytopenic purpura, autoimmune thyroid disease, multiple sclerosis, neuromyelitis optica and autoimmune liver diseases. Specific mention is given to those studies reporting an association of anti-H. pylori antibodies with the presence of autoimmune disease-specific clinical parameters, as well as those failing to find such associations. We also provide helpful hints for future research. PMID:24574735

'This is normal during pregnancy': a qualitative study of anaemia-related perceptions and practices among pregnant women in Mumbai, India.

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.

Autoimmune gastritis: Pathologist’s viewpoint

2015-01-01

Western countries are seeing a constant decline in the incidence of Helicobacter pylori-associated gastritis, coupled with a rising epidemiological and clinical impact of autoimmune gastritis. This latter gastropathy is due to autoimmune aggression targeting parietal cells through a complex interaction of auto-antibodies against the parietal cell proton pump and intrinsic factor, and sensitized T cells. Given the specific target of this aggression, autoimmune gastritis is typically restricted to the gastric corpus-fundus mucosa. In advanced cases, the oxyntic epithelia are replaced by atrophic (and metaplastic) mucosa, creating the phenotypic background in which both gastric neuroendocrine tumors and (intestinal-type) adenocarcinomas may develop. Despite improvements in our understanding of the phenotypic changes or cascades occurring in this autoimmune setting, no reliable biomarkers are available for identifying patients at higher risk of developing a gastric neoplasm. The standardization of autoimmune gastritis histology reports and classifications in diagnostic practice is a prerequisite for implementing definitive secondary prevention strategies based on multidisciplinary diagnostic approaches integrating endoscopy, serology, histology and molecular profiling.

We report a case of a 57-year-old woman with type I diabetes who had received a simultaneous pancreas-kidney (SPK) transplant maintained on tacrolimus, mycophenolic acid (MPA) and prednisolone. Her renal allograft failed 6 years post-transplant but she continued to have a normal functioning pancreatic allograft. Over the course of 5 years, she developed progressive bone marrow failure with repeat bone marrow aspirates demonstrating an evolution from erythroid hypoplasia to hypocellular marrow and eventual aplastic anaemia despite discontinuation of MPA and reduction of tacrolimus. She was transfusion-dependent and had frequent admissions for sepsis. Despite treatment with antithymocyte globulin and cyclosporine for aplastic anaemia, she developed fatal invasive pulmonary aspergillosis within 3 weeks of treatment. Even though the cause of aplastic anaemia is likely multifactorial, this case highlights the difficulty in balancing the need for versus the risk of ongoing immunosuppression in a SPK transplant recipient who continues to have normal pancreatic graft function. 2014 BMJ Publishing Group Ltd.

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.

Autoimmune liver disease in children.

Science.gov (United States)

Mieli-Vergani, G; Vergani, D

2003-03-01

Autoimmune liver disorders are characterised by an inflammatory liver histology, circulating non-organ specific autoantibodies and increased levels of immunoglobulin G (IgG) in the absence of a known aetiology. They respond to immunosuppressive treatment, which should be instituted as soon as diagnosis is made. Liver disorders with a likely autoimmune pathogenesis include autoimmune hepatitis (AIH) and autoimmune sclerosing cholangitis (ASC). Two types of AIH are recognised according to seropositivity for smooth muscle and/or antinuclear antibody (SMA/ANA, type 1) or liver kidney microsomal antibody (LKM1, type 2). There is a female predominance in both. LKM1-positive patients tend to present more acutely, at a younger age, and commonly have immunoglobulin A (IgA) deficiency, while duration of symptoms before diagnosis, clinical signs, family history of autoimmunity, presence of associated autoimmune disorders, response to treatment and long-term prognosis are similar in both groups. The most common type of paediatric sclerosing cholangitis is ASC. The clinical, biochemical, immunological and histological presentation of ASC is often indistinguishable from that of AIH. In both, there are high IgG, non-organ specific autoantibodies and interface hepatitis. Diagnosis is made by cholangiography. Children with ASC respond to immunosuppression satisfactorily and similarly to AIH in respect to remission and relapse rates, times to normalisation of biochemical parameters and decreased inflammatory activity on follow-up liver biopsies. However, the cholangiopathy can progress and there may be an evolution from AIH to ASC over the years, despite treatment. Whether the juvenile autoimmune form of sclerosing cholangitis and AIH are 2 distinct entities, or different aspects of the same condition, remains to be elucidated.

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

Impact of Autoantibodies against Glycolytic Enzymes on Pathogenicity of Autoimmune Retinopathy and Other Autoimmune Disorders

Directory of Open Access Journals (Sweden)

Grazyna Adamus

2017-04-01

Full Text Available Autoantibodies (AAbs against glycolytic enzymes: aldolase, α-enolase, glyceraldehyde-3-phosphate dehydrogenase, and pyruvate kinase are prevalent in sera of patients with blinding retinal diseases, such as paraneoplastic [cancer-associated retinopathy (CAR] and non-paraneoplastic autoimmune retinopathies, as well as in many other autoimmune diseases. CAR is a degenerative disease of the retina characterized by sudden vision loss in patients with cancer and serum anti-retinal AAbs. In this review, we discuss the widespread serum presence of anti-glycolytic enzyme AAbs and their significance in autoimmune diseases. There are multiple mechanisms responsible for antibody generation, including the innate anti-microbial response, anti-tumor response, or autoimmune response against released self-antigens from damaged, inflamed tissue. AAbs against enolase, GADPH, and aldolase exist in a single patient in elevated titers, suggesting their participation in pathogenicity. The lack of restriction of AAbs to one disease may be related to an increased expression of glycolytic enzymes in various metabolically active tissues that triggers an autoimmune response and generation of AAbs with the same specificity in several chronic and autoimmune conditions. In CAR, the importance of serum anti-glycolytic enzyme AAbs had been previously dismissed, but the retina may be without pathological consequence until a failure of the blood–retinal barrier function, which would then allow pathogenic AAbs access to their retinal targets, ultimately leading to damaging effects.

Paraneoplastic autoimmune movement disorders.

2017-11-01

To provide an overview of paraneoplastic autoimmune disorders presenting with various movement disorders. The spectrum of paraneoplastic autoimmune disorders has been expanding with the discovery of new antibodies against cell surface and intracellular antigens. Many of these paraneoplastic autoimmune disorders manifest as a form of movement disorder. With the discovery of new neuronal antibodies, an increasing number of idiopathic or neurodegenerative movement disorders are now being reclassified as immune-mediated movement disorders. These include anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis which may present with orolingual facial dyskinesia and stereotyped movements, CRMP-5 IgG presenting with chorea, anti-Yo paraneoplastic cerebellar degeneration presenting with ataxia, anti-VGKC complex (Caspr2 antibodies) neuromyotonia, opsoclonus-myoclonus-ataxia syndrome, and muscle rigidity and episodic spasms (amphiphysin, glutamic acid decarboxylase, glycine receptor, GABA(A)-receptor associated protein antibodies) in stiff-person syndrome. Movement disorders may be a presentation for paraneoplastic autoimmune disorders. Recognition of these disorders and their common phenomenology is important because it may lead to the discovery of an occult malignancy. Copyright © 2017 Elsevier Ltd. All rights reserved.

2017-01-01

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.

Diagnosis and classification of autoimmune orchitis.

Science.gov (United States)

Silva, C A; Cocuzza, M; Carvalho, J F; Bonfá, E

2014-01-01

Autoimmune orchitis is characterized by testis inflammation and the presence of specific antisperm antibodies (ASA). It is classified in two categories. Primary autoimmune orchitis is defined by infertility and asymptomatic orchitis associated with ASA (100%) directed to the basement membrane or seminiferous tubules in infertile men, without any systemic disease and usually asymptomatic. Secondary autoimmune orchitis is characterized by symptomatic orchitis and/or testicular vasculiti`s associated with a systemic autoimmune disease, particularly vasculitis. These patients typically demonstrate testicular pain, erythema and/or swelling. ASA in secondary autoimmune orchitis have been reported in up to 50% of patients, especially in systemic lupus erythematosus patients. The pathogenesis of primary as well as secondary autoimmune orchitis is still unknown. Although the etiology is likely to be multifactorial, testicular inflammation, infection or trauma may induce T cell response with pro-inflammatory cytokine production with a consequent blood-testis-barrier permeability alteration, ASA production and apoptosis of spermatocytes and spermatids. ASA is known to cause immobilization and/or agglutination of spermatozoa, which may block sperm-egg interaction resulting in infertility. Assisted reproduction has been used as an efficient option in primary cases and immunosuppressive therapy for secondary autoimmune orchitis, although there is no double-blind, randomized trial to confirm the efficacy of any treatment regimens for these conditions.

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.

Curcumin and autoimmune disease.

Science.gov (United States)

Bright, John J

2007-01-01

The immune system has evolved to protect the host from microbial infection; nevertheless, a breakdown in the immune system often results in infection, cancer, and autoimmune diseases. Multiple sclerosis, rheumatoid arthritis, type 1 diabetes, inflammatory bowel disease, myocarditis, thyroiditis, uveitis, systemic lupus erythromatosis, and myasthenia gravis are organ-specific autoimmune diseases that afflict more than 5% of the population worldwide. Although the etiology is not known and a cure is still wanting, the use of herbal and dietary supplements is on the rise in patients with autoimmune diseases, mainly because they are effective, inexpensive, and relatively safe. Curcumin is a polyphenolic compound isolated from the rhizome of the plant Curcuma longa that has traditionally been used for pain and wound-healing. Recent studies have shown that curcumin ameliorates multiple sclerosis, rheumatoid arthritis, psoriasis, and inflammatory bowel disease in human or animal models. Curcumin inhibits these autoimmune diseases by regulating inflammatory cytokines such as IL-1beta, IL-6, IL-12, TNF-alpha and IFN-gamma and associated JAK-STAT, AP-1, and NF-kappaB signaling pathways in immune cells. Although the beneficial effects of nutraceuticals are traditionally achieved through dietary consumption at low levels for long periods of time, the use of purified active compounds such as curcumin at higher doses for therapeutic purposes needs extreme caution. A precise understanding of effective dose, safe regiment, and mechanism of action is required for the use of curcumin in the treatment of human autoimmune diseases.

Auto-immune hepatitis first presenting in the early postpartum period is rare. Immunosuppressive effects of pregnancy result in delayed manifestation of auto-immune hepatitis, and in established cases, the spontaneous improvements are there. Auto-immune hepatitis should be considered in the differential diagnosis of liver dysfunction first presenting in the early postpartum period. A case of postpartum hepatitis of auto-immune aetiology is being presented here. It is disease of unknown aetiology, characterised by inflammation of liver (as evidenced by raised serum transaminases, presence of interface hepatitis on histological examination), hypergammaglobulinaemia (> 1.5 times normal), presence of auto-antibodies [(antinuclear antibodies (ANA)], smooth muscle antibody (SMA) and antibody to liver-kidney microsome type 1 (LKM1) in the absence of viral markers ie, hepatitis B (HBsAg) and C (AntiHCV) and excellent response to corticosteroid therapy.

Predictors of Persistent Anaemia in the First Year of Antiretroviral Therapy: A Retrospective Cohort Study from Goma, the Democratic Republic of Congo.

Pierre Zalagile Akilimali

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.

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.

Antipituitary antibodies (APA) but not antihypothalamus antibodies (AHA) are usually searched for in autoimmune hypopituitarism. Our objective was to search for AHA and characterize their hypothalamic target in patients with autoimmune hypopituitarism to clarify, on the basis of the cells stained by these antibodies, the occurrence of autoimmune subclinical/clinical central diabetes insipidus (CDI) and/or possible joint hypothalamic contribution to their hypopituitarism. We conducted a cross-sectional cohort study. Ninety-five APA-positive patients with autoimmune hypopituitarism, 60 without (group 1) and 35 with (group 2) lymphocytic hypophysitis, were studied in comparison with 20 patients with postsurgical hypopituitarism and 50 normal subjects. AHA by immunofluorescence and posterior pituitary function were evaluated; then AHA-positive sera were retested by double immunofluorescence to identify the hypothalamic cells targeted by AHA. AHA were detected at high titer in 12 patients in group 1 and in eight patients in group 2. They immunostained arginine vasopressin (AVP)-secreting cells in nine of 12 in group 1 and in four of eight in group 2. All AVP cell antibody-positive patients presented with subclinical/clinical CDI; in contrast, four patients with GH/ACTH deficiency but with APA staining only GH-secreting cells showed AHA targeting CRH- secreting cells. The occurrence of CDI in patients with lymphocytic hypophysitis seems due to an autoimmune hypothalamic involvement rather than an expansion of the pituitary inflammatory process. To search for AVP antibody in these patients may help to identify those of them prone to develop an autoimmune CDI. The detection of AHA targeting CRH-secreting cells in some patients with GH/ACTH deficiency but with APA targeting only GH-secreting cells indicates that an autoimmune aggression to hypothalamus is jointly responsible for their hypopituitarism.

Abstract Myasthenia gravis (MG) is a rare autoimmune disease of skeletal muscle endplates. MG subgroup is relevant for comorbidity, but usually not accounted for. MG patients have an increased risk for complicating autoimmune diseases, most commonly autoimmune thyroid disease, systemic lupus erythematosus and rheumatoid arthritis. In this review, we present concomitant autoimmune disorders associated with the different MG subgroups, and show how this influences treatment and prognosis. Concomitant MG should always be considered in patients with an autoimmune disorder and developing new neuromuscular weakness, fatigue or respiratory failure. When a second autoimmune disorder is suspected, MG should be included as a differential diagnosis. PMID:25915571

Autoimmune diseases are a group of heterogeneous inflammatory disorders characterized by systemic or localized inflammation, leading to ischemia and tissue destruction. These include disorders like systemic lupus erythematosus and related diseases, systemic vasculitides, and central nervous system (CNS) vasculitis (primary or secondary). Headache is a very common manifestation of CNS involvement of these diseases. Although headache characteristics can be unspecific and often non-diagnostic, it is important to recognize because headache can be the first manifestation of CNS involvement. Prompt recognition and treatment is necessary not only to treat the headache, but also to help prevent serious neurological sequelae that frequently accompany autoimmune diseases. In this review, we discuss headache associated with autoimmune diseases along with important mimics. © 2014 American Headache Society.

Autoimmune liver diseases may be associated with extrahepatic autoimmune pathology. We report the case of a 52-year old woman who initially presented to the gastroenterology department for extreme fatigue, pale stools, dark urine and pruritus. Laboratory tests showed significant cholestasis and elevation of aminotransferase levels. Immunological tests revealed positive antinuclear (ANA=1:320) and antimitochondrial antibodies (AMA=1:40) with negative anti-smooth muscle and liver kidney microsomal type 1 antibodies. The biopsy was compatible with overlap syndrome type 1. The patient was commenced on immunosuppressive therapy according to standard of care (azathioprine 50mg, ursodeoxycholic acid and prednisone 0.5mg/kg), with moderate biochemical improvement. She subsequently developed proximal symmetrical weakness and cutaneous involvement and was diagnosed with biopsy-proven dermatomyositis. The immunosuppressive regimen was intensified to 150 mg azathioprine. At the three-month follow-up, her symptoms subsided and aminotransferases and muscle enzymes normalized. Upon further investigation the patient was diagnosed with autoimmune thyroiditis and antiphospholipid syndrome. To our knowledge, this is the first case of primary biliary cirrhosis - autoimmune hepatitis overlap syndrome associated with dermatomyositis, autoimmune thyroiditis and antiphospholipid syndrome.

Bacterial pyomyositis is common in the tropids but is rare in temperate climates. A patient with aplastic anaemia who had never left the continental United States developed bacterial pyomyositis secondary to Staphylococcus aureus which responded to antibiotics and surgical drainage. Bacterial pyomyositis should be considered in the differential diagnosis of fever and myalgias in the immunocompromised patient.

Common autoimmune diseases tend to coexist in the same patients. Few studies have examined the possible association between autoimmune thyroiditis and psoriasis or psoriatic arthritis (PsA), with inconsistent results. To investigate the prevalence of autoimmune thyroiditis in psoriatic patients with or without PsA, living in an iodine-sufficient area. We studied prospectively, 114 psoriatic patients with disease duration of 5-38 years, 30 of them with PsA, and 286 age- and body mass index (BMI)-matched subjects without psoriasis or known thyroid disease or autoimmune disease. A detailed medical history was obtained from all participants and clinical examination and laboratory evaluation was performed. Psoriasis severity was assessed with Psoriasis Area and Severity Index (PASI). Autoimmune thyroiditis was defined by the presence of positive autoantibodies to thyroid peroxidase and/or thyroglobulin. There was no difference in the prevalence of autoimmune thyroiditis between psoriatic patients and controls (20.2% vs. 19.6%). The prevalence of autoimmune thyroiditis in male and female psoriatic patients was similar (9.6% and 10.5% respectively), in contrast to the increased, as expected, prevalence in female vs. male controls (14.7% vs. 4.9%, P thyroiditis were similar in psoriatic patients and controls (7.9% and 7.0% respectively). Autoimmune thyroiditis in psoriatic patients was not related with age of psoriasis onset, psoriasis duration, PASI score, PsA and obesity. These data support that psoriatic patients with or without PsA do not have an increased risk for autoimmune thyroiditis. © 2016 European Academy of Dermatology and Venereology.

Cutting-edge issues in autoimmune orchitis.

Science.gov (United States)

Silva, Clovis A; Cocuzza, Marcello; Borba, Eduardo F; Bonfá, Eloísa

2012-04-01

Autoimmune orchitis is a relevant cause of decreased fecundity in males, and it is defined as a direct aggression to the testis with the concomitant presence of anti-sperm antibodies (ASA). The presence of these specific antibodies has been observed in approximately 5-12% of infertile male partners. Primary autoimmune orchitis is defined by isolated infertility with ASA but without evidence of a systemic disease. Secondary causes of orchitis and/or testicular vasculitis are uniformly associated with autoimmune diseases, mainly in primary vasculitis such as polyarteritis nodosa, Behçet's disease, and Henoch-Schönlein purpura. The overall frequencies of acute orchitis and ASA in rheumatic diseases are 2-31% and 0-50%, respectively. The pathogenesis of primary/secondary autoimmune orchitis is not completely understood but probably involves the access of immune cells to the testicular microenvironment due to inflammation, infection or trauma, leading to apoptosis of spermatocytes and spermatids. Glucocorticoids and immunosuppressive drugs are indicated in autoimmune orchitis-associated active systemic autoimmune diseases. However, there are no standardized treatment options, and the real significance of ASA in infertile men is still controversial. Assisted reproductive technologies such as intrauterine insemination, in vitro fertilization, and intracytoplasmic sperm injection (ICSI) are therapeutic options for male infertility associated with these autoantibodies. ICSI is considered to be the best choice for patients with severe sperm autoimmunity, particularly in males with low semen counts or motility.

Full Text Available The prevalence of celiac disease autoimmunity or tissue transglutaminase autoantibodies (TGA amongst patients with type 1 diabetes (T1D and autoimmune thyroid disease (AITD in the Chinese population remains unknown. This study examined the rate of celiac disease autoimmunity amongst patients with T1D and AITD in the Chinese population. The study included 178 patients with type 1 diabetes and 119 with AITD where 36 had both T1D and AITD, classified as autoimmune polyglandular syndrome type 3 variant (APS3v. The study also included 145 patients with type 2 diabetes (T2D, 97 patients with non-autoimmune thyroid disease (NAITD, and 102 healthy controls. Serum islet autoantibodies, thyroid autoantibodies and TGA were measured by radioimmunoassay. TGA positivity was found in 22% of patients with either type 1 diabetes or AITD, much higher than that in patients with T2D (3.4%; p< 0.0001 or NAITD (3.1%; P < 0.0001 or healthy controls (1%; p<0.0001. The patients with APS3v having both T1D and AITD were 36% positive for TGA, significantly higher than patients with T1D alone (p = 0.040 or with AITD alone (p = 0.017. T1D and AITD were found to have a 20% and 30% frequency of overlap respectively at diagnosis. In conclusion, TGA positivity was high in the Chinese population having existing T1D and/or AITD, and even higher when both diseases were present. Routine TGA screening in patients with T1D or AITD will be important to early identify celiac disease autoimmunity for better clinical care of patients.

Combined Acute Haemolytic and Secondary Angle Closure Glaucoma following Spontaneous Intraocular Haemorrhages in a Patient on Warfarin

Full Text Available Background: To report the first described case of combined haemolytic and acute angle closure glaucoma secondary to spontaneous intraocular haemorrhages in a patient on excessive anticoagulation. To the best of our knowledge, this is the first case reported in the literature presenting with raised intraocular pressure due to both mechanisms. Case Description: A 90-year-old woman presented with acute pain and reduction in vision in the left eye. Her intraocular pressure (IOP was 55 mm Hg. There were red tinted blood cells in the anterior chamber giving it a reddish hue. The patient was known to have advanced wet macular degeneration. She was taking oral warfarin for atrial fibrillation. Her international normalised ratio (INR was 7.7. B-scan ultrasound of posterior segment showed vitreous and suprachoroidal haemorrhages. An ultrabiomicroscopic examination confirmed open angles. A diagnosis of haemolytic glaucoma secondary to intraocular haemorrhages was made. The IOP was controlled medically. Warfarin was withdrawn and oral vitamin K therapy was initiated leading to a rapid INR reduction. Three days later, her anterior chamber became progressively shallower causing a secondary acute angle closure which was managed medically. After 2 months, the left IOP was well-controlled without any medications and the eye was not inflamed. Her vision in that eye remained perception of light. Conclusion: Patients with suprachoroidal haemorrhages should be closely monitored as they might subsequently develop acute angle closure despite an initially open angle and well-controlled INR and IOP. Excessive anticoagulation needs to be prevented to minimise the risk of sight-threatening complications.

Impact of hookworm infection and deworming on anaemia in non-pregnant populations: a systematic review.

Smith, Jennifer L; Brooker, Simon

2010-07-01

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.

Regulatory T-cells and autoimmunity.

LENUS (Irish Health Repository)

Ni Choileain, Niamh

2012-02-03

Approximately 20% of the population is affected by autoimmune or inflammatory diseases mediated by an abnormal immune response. A characteristic feature of autoimmune disease is the selective targeting of a single cell type, organ or tissue by certain populations of autoreactive T-cells. Examples of such diseases include rheumatoid arthritis, insulin-dependent diabetes mellitus, and systemic lupus erythematosus (SLE), all of which are characterized by chronic inflammation, tissue destruction and target organ malfunction. Although strong evidence links most autoimmune diseases to specific genes, considerable controversy prevails regarding the role of regulatory T-cell populations in the disease process. These cells are now also believed to play a key role in mediating transplantation tolerance and inhibiting the induction of tumor immunity. Though the concept of therapeutic immune regulation aimed at treating autoimmune pathology has been validated in many animal models, the development of strategies for the treatment of human autoimmune disorders remains in its infancy. The main obstacles to this include the conflicting findings of different model systems, as well as the contrasting functions of regulatory T-cells and cytokines involved in the development of such disorders. This review examines the role of regulatory T-cells in the pathogenesis of autoimmunity and describes the therapeutic potential of these cells for the prevention of immune-mediated pathologies in the future. Although much remains to be learned about such pathologies, a clearer understanding of the mechanisms by which regulatory T-cells function will undoubtedly lead to exciting new possibilities for immunotherapeutics.

Multiple Autoimmune Syndromes Associated with Psoriasis: A Rare Clinical Presentation

Directory of Open Access Journals (Sweden)

Sadia Masood

2014-03-01

Full Text Available Autoimmune diseases are known to have association with each other but it is very rare to see multiple autoimmune diseases in one patient. The combination of at least three autoimmune diseases in the same patient is referred to as multiple autoimmune syndrome. The case we are reporting features multiple autoimmune syndrome with five different conditions. The patient had type 1 diabetes mellitus, autoimmune hemolytic anemia, systemic lupus erythematosus, vitiligo, and psoriasis. Psoriasis has rarely been reported previously under the spectrum of autoimmune syndrome. Although the relationship of autoimmune conditions with each other has been explored in the past, this case adds yet another dimension to the unique evolution of autoimmune pathologies. The patient presented with a combination of five autoimmune diseases, which makes it consistent type three multiple autoimmune syndromes with the addition of psoriasis. The current case is unique in this aspect that the combination of these five autoimmune disorders has never been reported in the past.

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

Full Text Available We are reporting a rare case of severe hemolytic disease of newborn (HDN with Bombay phenotype mother. A retrospective study of a case with severe haemolytic disease of newborn with Bombay phenotype mother was done. Blood grouping, antibody screening, and lectin study was done on the blood sample of the baby and mother to confirm the diagnosis. Hematological and biochemical parameters were obtained from the hospital laboratory information system for the analysis. Blood group of the baby was A positive, direct antiglobulin test was negative. Blood group of the mother was confirmed to be Bombay phenotype, Hematological parameters showed all the signs of ongoing hemolysis and the bilirubin level was in the zone of exchange transfusion. Due to the unavailability of this rare phenotype blood unit, baby was managed conservatively. Anticipating the fetal anemia and HDN with mothers having Bombay phenotype and prior notification to the transfusion services will be of great help in optimizing the neonatal care and outcome.

The localized scleroderma (LS) known as morphea, presents a variety of clinical manifestations that can include systemic involvement. Current classification schemes divide morphea into categories based solely on cutaneous morphology, without reference to systemic disease or autoimmune phenomena. This classification is likely incomplete. Autoimmune phenomena such as vitiligo and Hashimoto thyroiditis associated with LS have been reported in some cases suggesting an autoimmune basis. To our knowledge this is the first case of a morphea forming part of a multiple autoimmune syndrome (MAS) and presenting simultaneously with autoimmune thrombocytopenic purpura and central nervous system vasculitis. We report an uncommon case of a white 53 year old female patient with LS as part of a multiple autoimmune syndrome associated with pneumonitis, autoimmune thrombocytopenic purpura and central nervous system vasculitis presenting a favorable response with thrombopoietin receptor agonists, pulses of methylprednisolone and cyclophosphamide. Is likely that LS have an autoimmune origin and in this case becomes part of MAS, which consist on the presence of three or more well-defined autoimmune diseases in a single patient.

Iron deficiency is the commonest treatable cause of postpartum anaemia. Parenteral iron therapy results in faster and higher replenishment of iron stores and correction of haemoglobin levels with better compliance. Ferric Carboxy Maltose is an effective and a safe option which can be administered intravenously in single total correction dose without any serious adverse effects.The study was done to evaluate the efficacy and safety of Ferric Carboxy Maltose in the treatment of iron deficiency anaemia in post-natal patients. It was an open, single arm study including 615 women with diagnosis of Iron deficiency anaemia and haemoglobin (Hb) levels between 4gm% and 11gm% from January 2013 to December 2016. Intravenous Ferric Carboxy Maltose(500-1500mg) was administered and the improvement in haemoglobin levels and iron stores were assessed after three weeks of total dose infusion. Out of the 615 women, 595 women were included in the analysis. Most of the women were in the age group of 27-30 years. Most of the women had mild anaemia as per World Health Organisation guidelines. Mean hemoglobin levels significantly increased over a period of three weeks after Ferric Carboxy Maltose administration. Other parameters like total iron binding capacity, Ferritin and Iron also had a significant improvement after Ferric Carboxy Maltose administration. No serious adverse events were observed after Ferric Carboxy Maltose. Intravenous Ferric Carboxy Maltose was an effective and a safe treatment option for iron deficiency anaemia and has an advantage of single administration of high doses without serious adverse effects.

Atypical haemolytic uraemic syndrome is one of the main variants of thrombotic microangiopathy, and is characterized by excessive complement activation in the microvasculature. It is also characterised by the clinical triad; non-immune haemolytic anaemia, thrombocytopenia, and acute renal failure. In addition, 60% of patients have mutations in the genes encoding complement regulators (factor H, factor I, membrane cofactor proteins, and thrombomodulin), activators (factor B and C3), as well as autoantibodies against factor H. Multiple factors are required for the disease to manifest itself, including a trigger and gene mutations with adequate penetration. Being one of the differential diagnoses of preeclampsia- eclampsia and HELLP syndrome means that the clinician must be familiar with the disease due to its high mortality, which can be modified with early diagnosis and comprehensive treatment.

Why is multiple micronutrient powder ineffective at reducing anaemia among 12–24 month olds in Colombia? Evidence from a randomised controlled trial

Directory of Open Access Journals (Sweden)

Full Text Available In Colombia’s bottom socio-economic strata, 46.6% of children under two are anaemic. A prevalence of above 20% falls within the WHO guidelines for daily supplementation with multiple micronutrient powder (MNP. To evaluate the effect of daily MNP supplementation on anaemia amongst Colombian children aged 12–24 months we ran a cluster RCT (n=1440. In previous work, we found the intervention had no impact on haemoglobin or anaemia in this population. In this current paper, we investigate this null result and find it cannot be explained by an underpowered study design, inaccurate measurements, low adoption of and compliance with the intervention, or crowding out through dietary substitution. We conclude that our intervention was ineffective at reducing rates of childhood anaemia because MNP itself was inefficacious in our population, rather than poor implementation of or adherence to the planned intervention. Further analysis of our data and secondary data suggests that the evolution with age of childhood anaemia in Colombia, and its causes, appear different from those in settings where MNP has been effective. Firstly, rates of anaemia peak at much earlier ages and then fall rapidly. Secondly, anaemia that remains after the first year of life is relatively, and increasingly as children get older, unrelated to iron deficiency. We suggest that factors during gestation, birth, breastfeeding and early weaning may be important in explaining very high rates of anaemia in early infancy. However, the adverse effects of these factors appear to be largely mitigated by the introduction of solid foods that often include meat. This renders population wide MNP supplementation, provided after a diet of solid foods has become established, an ineffective instrument with which to target Colombia’s childhood anaemia problem.

Human neutrophils in auto-immunity.

Science.gov (United States)

Thieblemont, Nathalie; Wright, Helen L; Edwards, Steven W; Witko-Sarsat, Véronique

2016-04-01

Human neutrophils have great capacity to cause tissue damage in inflammatory diseases via their inappropriate activation to release reactive oxygen species (ROS), proteases and other tissue-damaging molecules. Furthermore, activated neutrophils can release a wide variety of cytokines and chemokines that can regulate almost every element of the immune system. In addition to these important immuno-regulatory processes, activated neutrophils can also release, expose or generate neoepitopes that have the potential to break immune tolerance and result in the generation of autoantibodies, that characterise a number of human auto-immune diseases. For example, in vasculitis, anti-neutrophil cytoplasmic antibodies (ANCA) that are directed against proteinase 3 or myeloperoxidase are neutrophil-derived autoantigens and activated neutrophils are the main effector cells of vascular damage. In other auto-immune diseases, these neutrophil-derived neoepitopes may arise from a number of processes that include release of granule enzymes and ROS, changes in the properties of components of their plasma membrane as a result of activation or apoptosis, and via the release of Neutrophil Extracellular Traps (NETs). NETs are extracellular structures that contain chromatin that is decorated with granule enzymes (including citrullinated proteins) that can act as neo-epitopes to generate auto-immunity. This review therefore describes the processes that can result in neutrophil-mediated auto-immunity, and the role of neutrophils in the molecular pathologies of auto-immune diseases such as vasculitis, rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). We discuss the potential role of NETs in these processes and some of the debate in the literature regarding the role of this phenomenon in microbial killing, cell death and auto-immunity.

To identify correlates of hemoglobin (Hb) and anaemia unexplained by iron deficiency (UA) in Canadian Inuit adults. A cross-sectional survey assessed diet, demographic information, anthropometry, fasting Hb, ferritin, soluble transferrin receptor (on a subset), high-sensitivity C-reactive protein (hs-CRP) in serum, red blood cell (RBC) fatty acid composition, blood lead, and antibodies to Helicobacter pylori in non-pregnant, Inuit adults (n = 2550), ≥18 years of age from randomly selected households in 36 Inuit communities in Inuvialuit Settlement Region, Nunavut Territory and Nunatsiavut of Northern Labrador, Canada. Hb concentrations were lower and UA prevalence higher in Inuit men after 50 years of age. Rate of anaemia was constant among Inuit women but changed from primarily iron deficiency anaemia pre-menopause, to primarily UA in post-menopause. Low education levels and hs-CRP were associated with increased risk of UA. For Inuit men, % RBC eicosapentaenoic acid (EPA) and elevated blood lead were also associated with increased risk of UA. Frequency of traditional food intake was positively associated with Hb. Age patterns and regional variation of anaemia suggest that ethnicity-related physiological differences cannot explain anaemia prevalence for Inuit. High RBC EPA status, inflammation and infections, and lower education levels may contribute to the prevalence of anaemia in this population, which is not related to iron status. Thus, traditional lifestyle may protect Inuit from nutritional anaemia but contribute to lower Hb through environmental exposures. The clinical significance of UA for older Inuit adults requires further investigation, as the prevalence represents a moderate public health problem.

Intravenous iron sucrose therapy for moderate to severe anaemia in pregnancy

2013-01-01

Full Text Available Background & objectives: 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. Methods: 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. Results: The mean haemoglobin raised from 7.63 ± 0.61 to 11.20 ± 0.73 g% (P<0.001 after eight wk of therapy. There was significant rise in serum ferritin levels (from 11.2 ± 4.7 to 69 ± 23.1 μg/l (P<0.001. Reticulocyte count increased significantly after two wk of starting therapy (from 1.5 ± 0.6 to 4.6±0.8%.Other parameters including serum iron levels and red cell indices were also improved significantly. Only one woman was lost to follow up. No major side effects or anaphylactic reactions were noted during study period. Interpretation & conclusions: Parentral iron therapy was effective in increasing haemoglobin, serum ferritin and other haematological parameters in pregnant women with moderate anaemia. 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

The potential application of radioisotopes are not discussed in this review of trypanosome pathogenesis in cattle. Initially, structural changes in the lymphoid system are characterized by marked proliferation and germinal centre formation, whereas in long-standing infections the lymphoid organs become depleted. These changes appear associated with immunodepression. Anaemia dominates the clinical disease syndrome in bovine trypanosomiasis. It develops with the onset of parasitaemia and is largely haemolytic, resulting from increased red blood cell destruction by phagocytosis. Several factors may be involved in this process including haemolysins produced by the trypanosome, immunological mechanisms, fever, disseminated intravascular coagulation and an expanded and active mononuclear phagocytic system. During this phase of the disease, cattle respond well to chemotherapy. However, in later phases of the disease, when trypanosomes cannot be detected, the anaemia sometimes persists and animals do not respond to treatment. Concerning the underlying mechanisms responsible for the anaemia, continued red cell destruction combined with some dyshaemopoiesis, associated with a defect in iron metabolism, appears responsible. Widespread tissue degeneration occurs. Organs particularly severely affected include the heart. Death in bovine trypanosomiasis is presumably due to a combination of anaemia, microcirculatory disturbances and myocardial damage. The factors incriminated in tissue damage probably vary with the species of trypanosome involved, although under natural field conditions it is common to find T. congolense, T. vivax and T. brucei in one animal. Likely pathogenic mechanisms in bovine include anoxia as a result of anaemia, microcirculatory disorders and hypersensitivity reactions

Preventive Treatments of Iron Deficiency Anaemia in Pregnancy: A Review of Their Effectiveness and Implications for Health System Strengthening

Full Text Available Objectives. We conducted a review of effectiveness of preventive treatments of iron deficiency anaemia in pregnancy in developing countries and highlighted their constraints as well as interventions required to strengthen the health services. Methods. Literature from Pubmed (MEDLINE, AJOL, Google Scholar, and Cochrane database was reviewed. Results. Evidence-based preventive treatment options for iron deficiency anaemia in pregnancy include prophylaxis iron supplements and food fortification with iron. Evidence abounds on their effectiveness in reducing the prevalence of iron deficiency anaemia in pregnancy. However, these prospects are threatened by side effects of iron supplements, low utilization of maternal health service in developing countries, partial implementation of preventive treatments, and weak infrastructure and political commitment to implement mass fortification of local staple foods by national governments. Conclusion. Sustainability of effectiveness of preventive treatments of iron deficiency anaemia in pregnancy could be achieved if the identified threats are adequately addressed.

Autoimmune hepatitis (AIH) is characterised histologically by interface hepatitis, and serologically by the presence of non-organ and liver specific autoantibodies and increased levels of immunoglobulin G. Its onset is often ill-defined, frequently mimicing acute hepatitis. AIH usually responds to immunosuppressive treatment, which should be instituted as soon as diagnosis is made. Two types of AIH are recognized according to seropositivity for smooth muscle and/or antinuclear antibody (SMA/ANA, type 1 AIH) or liver kidney microsomal type 1 antibody (LKM1, type 2 AIH). There is a female predominance in both. LKM1 positive patients tend to present more acutely, at a younger age and commonly have immunoglobulin A deficiency, while duration of symptoms before diagnosis, clinical signs, family history of autoimmunity, presence of associated autoimmune disorders, response to treatment and long-term prognosis are similar in the 2 groups. Susceptibility to AIH type 1 is conferred by possession of HLA DR3 and DR4, while to AIH type 2 by possession of HLA DR7. Liver damage is likely to derive from an immune reaction to liver cell antigens, possibly triggered by a mechanism of molecular mimicry, where immune responses to external pathogens, e.g. viruses, become directed towards structurally similar self-components. In AIH this process would be perpetuated by impairment in immune regulation.

Autoimmune connective tissue diseases and vaccination

Full Text Available The idea that infectious agents can induce autoimmune diseases in genetically susceptible subjects has been a matter of discussion for years. Moreover, increased incidence of autoimmune diseases and introduction of prophylactic vaccinations from early childhood suggest that these two trends are linked. In the medical literature and even non-professional media, case reports or events temporally related to vaccination are reported. It raises the issue of vaccination safety. In everyday practice medical professionals, physicians, rheumatologists and other specialists will be asked their opinion of vaccination safety. The decision should be made according to evidence-based medicine and the current state of knowledge. The purpose of this paper is to discuss a potential mechanism which links infections, vaccinations and autoimmunity. We present an overview of published case reports, especially of systemic connective tissue diseases temporally related to vaccination and results from case-nested studies. As yet, no conclusive evidence supports a causal relationship between vaccination and autoimmune diseases. It has to be determined whether the performed studies are sufficiently Epsteinasensitive to detect the link. The debate is ongoing, and new data may be required to explain the pathogenesis of autoimmunity. We would like to underscore the need for prophylactic vaccination in patients with autoimmune rheumatic diseases and to break down the myth that the vaccines are contraindicated in this target group.

Iron deficiency is the most common cause of anaemia in the world. Despite frequently weak and masked clinical presentation of iron deficiency anaemia (IDA), this disease is very serious with complications leading to early mortality. In the developed countries IDA is predominantly diagnosed as the complication of another disease or as the result of major bleeding events. Diagnosis of IDA should be based on laboratory findings i.e. haemoglobin, mean corpuscular hemoglobin concentration and ferritin. Latter is the most sensitive marker for iron deficiency. Anaemia of chronic disease should be taken into an account as a potential differential diagnosis or coexisting state. For women in fertility age with IDA, gynaecological disorders should be ruled out first. Males and postmenopausal women with IDA should undergo upper, lower and in certain cases capsule endoscopy and/or enteroscopy to find a plausible cause of IDA. The ultimate goal of therapy is to find out and treat the primary cause of IDA. Iron body stores should be restored using either oral or parenteral iron preparations. The use of parenteral iron preparations in patients with gastrointestinal pathologies is often clinically substantiated for the treatment of IDA. Red blood cell transfusion should be administered in emergency cases only.

Anaemia is frequently associated with both HIV-infection and HIV-related tuberculosis (TB) in antiretroviral therapy (ART)-naïve patients in sub-Saharan Africa and is strongly associated with poor prognosis. However, the effect of ART on the resolution of anaemia in patient cohorts with a high prevalence and incidence of tuberculosis is incompletely defined and the impact of TB episodes on haemoglobin recovery has not previously been reported. We therefore examined these issues using data from a well-characterised cohort of patients initiating ART in South Africa. Prospectively collected clinical and haematological data were retrospectively analysed from patients receiving ART in a South African township ART service. TB diagnoses and time-updated haemoglobin concentrations, CD4 counts and HIV viral loads were recorded. Anaemia severity was classified according to WHO criteria. Multivariable logistic regression analysis was used to determine factors independently associated with anaemia after 12 months of ART. Of 1,140 patients with baseline haemoglobin levels, 814 were alive in care and had repeat values available after 12 months of ART. The majority of patients were female (73%), the median CD4 count was 104 cells/uL and 30.5% had a TB diagnosis in the first year of ART. At baseline, anaemia (any severity) was present in 574 (70.5%) patients and was moderate/severe in 346 (42.5%). After 12 months of ART, 218 (26.8%) patients had anaemia of any severity and just 67 (8.2%) patients had moderate/severe anaemia. Independent predictors of anaemia after 12 months of ART included greater severity of anaemia at baseline, time-updated erythrocyte microcytosis and receipt of an AZT-containing regimen. In contrast, prevalent and/or incident TB, gender and baseline and time-updated CD4 cell count and viral load measurements were not independent predictors. Although anaemia was very common among ART-naive patients, the anaemia resolved during the first year of ART in a

Monogenic autoimmune diseases of the endocrine system.

The most common endocrine diseases, type 1 diabetes, hyperthyroidism, and hypothyroidism, are the result of autoimmunity. Clustering of autoimmune endocrinopathies can result from polygenic predisposition, or more rarely, may present as part of a wider syndrome due to a mutation within one of seven genes. These monogenic autoimmune diseases show highly variable phenotypes both within and between families with the same mutations. The average age of onset of the monogenic forms of autoimmune endocrine disease is younger than that of the common polygenic forms, and this feature combined with the manifestation of other autoimmune diseases, specific hallmark features, or both, can inform clinicians as to the relevance of genetic testing. A genetic diagnosis can guide medical management, give an insight into prognosis, inform families of recurrence risk, and facilitate prenatal diagnoses. Copyright © 2016 Elsevier Ltd.

Selected Aspects in the Pathogenesis of Autoimmune Diseases

Directory of Open Access Journals (Sweden)

György Nagy

Full Text Available Autoimmune processes can be found in physiological circumstances. However, they are quenched with properly functioning regulatory mechanisms and do not evolve into full-blown autoimmune diseases. Once developed, autoimmune diseases are characterized by signature clinical features, accompanied by sustained cellular and/or humoral immunological abnormalities. Genetic, environmental, and hormonal defects, as well as a quantitative and qualitative impairment of immunoregulatory functions, have been shown in parallel to the relative dominance of proinflammatory Th17 cells in many of these diseases. In this review we focus on the derailed balance between regulatory and Th17 cells in the pathogenesis of autoimmune diseases. Additionally, we depict a cytokine imbalance, which gives rise to a biased T-cell homeostasis. The assessment of Th17/Treg-cell ratio and the simultaneous quantitation of cytokines, may give a useful diagnostic tool in autoimmune diseases. We also depict the multifaceted role of dendritic cells, serving as antigen presenting cells, contributing to the development of the pathognomonic cytokine signature and promote cellular and humoral autoimmune responses. Finally we describe the function and role of extracellular vesicles in particular autoimmune diseases. Targeting these key players of disease progression in patients with autoimmune diseases by immunomodulating therapy may be beneficial in future therapeutic strategies.

Radiosensitivity in Fanconi anaemia: application to the conditioning regimen for bone marrow transplantation

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.

Autoimmune Syndrome Induced by Adjuvant (ASIA) is a definition aimed to describe the common etiological process at the root of five clinical entities sharing similar symptomatology: macrophagic myofasciitis syndrome (MMF), Gulf War Syndrome (GWS), sick building syndrome (SBS), siliconosis, and post vaccination autoimmune phenomena. ASIA illustrates the role of environmental immune stimulating agents, or adjuvants, in the instigation of complex autoimmune reactions among individuals bearing a genetic preponderance for autoimmunity. The value of ASIA lies first in the acknowledgment it provides for patients suffering from these as yet ill-defined medical conditions. Equally important is the spotlight it sheds for further research of these poorly understood conditions sharing a common pathogenesis. In this article we elaborate on the significance of ASIA, review the current evidence in support of the syndrome, and address recent reservations raised regarding its validity.

Iron deficiency anaemia is a common problem in pregnancy despite national recommendations and guidelines for treatment. The aim of this study was to appraise the evidence against the UK National Screening Committee (UKNSC) criteria as to whether a national screening programme could reduce the prevalence of iron deficiency anaemia and/or iron deficiency in pregnancy and improve maternal and fetal outcomes. Search strategies were developed for the Cochrane library, Medline and Embase to identify evidence relevant to UK National Screening Committee (UKNSC) appraisal criteria which cover the natural history of iron deficiency and iron deficiency anaemia, the tests for screening, clinical management and evidence of cost effectiveness. Many studies evaluated haematological outcomes of anaemia, but few analysed clinical consequences. Haemoglobin and ferritin appeared the most suitable screening tests, although future options may follow recent advances in understanding iron homeostasis. The clinical consequences of iron deficiency without anaemia are unknown. Oral and intravenous iron are effective in improving haemoglobin and iron parameters. There have been no trials or economic evaluations of a national screening programme for iron deficiency anaemia in pregnancy. Iron deficiency in pregnancy remains an important problem although effective tests and treatment exist. A national screening programme could be of value for early detection and intervention. However, high quality studies are required to confirm whether this would reduce maternal and infant morbidity and be cost effective.

Leaky gut and autoimmune diseases.

Science.gov (United States)

Fasano, Alessio

2012-02-01

Autoimmune diseases are characterized by tissue damage and loss of function due to an immune response that is directed against specific organs. This review is focused on the role of impaired intestinal barrier function on autoimmune pathogenesis. Together with the gut-associated lymphoid tissue and the neuroendocrine network, the intestinal epithelial barrier, with its intercellular tight junctions, controls the equilibrium between tolerance and immunity to non-self antigens. Zonulin is the only physiologic modulator of intercellular tight junctions described so far that is involved in trafficking of macromolecules and, therefore, in tolerance/immune response balance. When the zonulin pathway is deregulated in genetically susceptible individuals, autoimmune disorders can occur. This new paradigm subverts traditional theories underlying the development of these diseases and suggests that these processes can be arrested if the interplay between genes and environmental triggers is prevented by re-establishing the zonulin-dependent intestinal barrier function. Both animal models and recent clinical evidence support this new paradigm and provide the rationale for innovative approaches to prevent and treat autoimmune diseases.

We present history of 16-year-old boy, HBsAg carrier, treated with interferon alpha at the age of 6 because of hepatitis B (HBeAg/antyHBe seroconversion). In August 2002--admitted to Department of Pediatric Oncology due to pancytopenia--diagnosis of severe aplastic anaemia was made (bone marrow cellularity--10%). We found no relative donor for hematopoietic cells transplantation and started immunosuppresive therapy (ATG, G-CSF, methyloprednisolon, cyclosporin). Haematologic parameters were improving. At day +60 he was admitted to our Department due to the increase in aminotransferases and cyclosporin activity. He was treated with cefuroxim, acyclovir and drugs improving liver cell function, cyclosporin was stopped. Presence of HBV DNA in serum confirmed HBV reactivation--a boy received lamivudine and cyclosporin again (as a maintenance therapy of aplastic anaemia). Aminotransferase activity and haematological parameters returned to normal. This case indicates the possibility of HBV reactivation in the course of immunosuppressive therapy (e.g. after antithymocytic globulin and cyclosporin) for aplastic anaemia.

HIV-infected pregnant women are particularly more susceptible to the deleterious effects of malaria infection particularly anaemia. In order to prevent opportunistic infections and malaria, a policy of daily co-trimoxazole prophylaxis without the standard Suphadoxine-Pyrimethamine intermittent preventive treatment (SP-IPT) was introduced to all HIV infected pregnant women in the year 2011. However, there is limited information about the effectiveness of this policy. This was a cross sectional study conducted among HIV-infected pregnant women receiving co-trimoxazole prophylaxis in eight public health facilities in Kinondoni Municipality from February to April 2013. Blood was tested for malaria infection and anaemia (haemoglobin anaemia. Pearson chi-square test, Fischer's exact test and multivariate logistic regression were used in the statistical analysis. This study enrolled 420 HIV infected pregnant women. The prevalence of malaria infection was 4.5%, while that of anaemia was 54%. The proportion of subjects with poor adherence to co-trimoxazole was 50.5%. As compared to HIV infected pregnant women with good adherence to co-trimoxazole prophylaxis, the poor adherents were more likely to have a malaria infection (Adjusted Odds Ratio, AOR = 6.81, 95% CI = 1.35-34.43, P = 0.02) or anaemia (AOR = 1.75, 95% CI = 1.03-2.98, P = 0.039). Other risk factors associated with anaemia were advanced WHO clinical stages, current malaria infection and history of episodes of malaria illness during the index pregnancy. The prevalence of malaria was low; however, a significant proportion of subjects had anaemia. Good adherence to co-trimoxazole prophylaxis was associated with reduction of both malaria infection and anaemia among HIV infected pregnant women.

Since resolution of malaria restores erythropoiesis, we hypothesized that drug-resistant strains of Plasmodium falciparum would increase the risk of severe anaemia developing from initially uncomplicated malaria. Using both in vivo and in vitro drug-sensitivity tests we...... compared the prevalence of drug-resistant malaria between severe malarial anaemia SA and non-anaemic malaria NAM patients. Assessment of treatment outcome using the WHO in vivo criteria showed no significant difference in parasite resistance between the two groups. The mean parasite clearance time was also......-treatment blood levels of chloroquine did not differ much between the two groups.

Turner syndrome is associated with increased incidence of autoimmune diseases, especially those of the thyroid gland. The aim of this study was to assess the prevalence of thyroid autoimmunity among pediatric patients with Turner syndrome. The study was retrospective and included 41 girls with Turner syndrome aged 6-18 years. Free thyroxine (FT4), thyroid stimulating hormone (TSH), anti-thyroid peroxidase (TPO-Ab) antibodies, anti-thyroglobulin (TG-Ab) antibodies, and karyotype were investigated. The correlation between karyotype and incidence of thyroid autoimmunity was also examined. Eleven patients (26.8%) were positive for TPO-Ab and/or TG-Ab. Three girls from that subgroup were euthyroid, 5 had subclinical hypothyroidism, and 3 were diagnosed with overt hypothyroidism. Out of these 11 patients affected by thyroid autoimmunity, 6 girls had mosaic karyotype with X-isochromosome (n = 4) or with deletions (n = 2), and 5 had the 45,X karyotype. The study findings confirmed a high incidence of thyroid autoimmunity in girls with Turner syndrome, but we failed to observe an association between the incidence of thyroid autoimmunity and karyotype. We conclude that it is important to monitor thyroid function in patients with Turner syndrome because they are prone to develop hypothyroidism.

NK cell autoreactivity and autoimmune diseases

Directory of Open Access Journals (Sweden)

Full Text Available Increasing evidences have pointed out the relevance of Natural Killer (NK cells in organ specific and systemic autoimmune diseases. NK cells bear a plethora of activating and inhibiting receptors that can play a role in regulating reactivity with autologous cells. The activating receptors recognize natural ligands upregulated on virus-infected or stressed or neoplastic cells. Of note, several autoimmune diseases are thought to be linked to viral infections as one of the first event in inducing autoimmunity. Also, it is conceivable that autoimmunity can be triggered when a dysregulation of innate immunity occurs, activating T and B lymphocytes to react with self-components. This would imply that NK cells can play a regulatory role during adaptive immunity; indeed, innate lymphoid cells (ILC, comprising the classical CD56+ NK cells, have a role in maintaining or alterating tissue homeostasis secreting protective and/or proinflammatory cytokines. In addition, NK cells display activating receptors involved in natural cytotoxicity and the activating isoforms of receptors for HLA class I that can interact with healthy host cells and induce damage without any evidence of viral infection or neoplastic-induced alteration. In this context, the interrelationship among ILC, extracellular matrix components and mesenchymal stromal cells can be considered a key point for the control of homeostasis. Herein, we summarize evidences for a role of NK cells in autoimmune diseases and will give a point of view of the interplay between NK cells and self-cells in triggering autoimmunity.

Saccharomyces cerevisiae is best known as the baker's and brewer's yeast, but its residual traces are also frequent excipients in some vaccines. Although anti-S. cerevisiae autoantibodies (ASCAs) are considered specific for Crohn's disease, a growing number of studies have detected high levels of ASCAs in patients affected with autoimmune diseases as compared with healthy controls, including antiphospholipid syndrome, systemic lupus erythematosus, type 1 diabetes mellitus, and rheumatoid arthritis. Commensal microorganisms such as Saccharomyces are required for nutrition, proper development of Peyer's aggregated lymphoid tissue, and tissue healing. However, even the commensal nonclassically pathogenic microbiota can trigger autoimmunity when fine regulation of immune tolerance does not work properly. For our purposes, the protein database of the National Center for Biotechnology Information (NCBI) was consulted, comparing Saccharomyces mannan to several molecules with a pathogenetic role in autoimmune diseases. Thanks to the NCBI bioinformation technology tool, several overlaps in molecular structures (50-100 %) were identified when yeast mannan, and the most common autoantigens were compared. The autoantigen U2 snRNP B″ was found to conserve a superfamily protein domain that shares 83 % of the S. cerevisiae mannan sequence. Furthermore, ASCAs may be present years before the diagnosis of some associated autoimmune diseases as they were retrospectively found in the preserved blood samples of soldiers who became affected by Crohn's disease years later. Our results strongly suggest that ASCAs' role in clinical practice should be better addressed in order to evaluate their predictive or prognostic relevance.

Autoimmune Addison's disease.

Addison's disease is a rare autoimmune disorder. In the developed world, autoimmune adrenalitis is the commonest cause of primary adrenal insufficiency, where the majority of patients have circulating antibodies against the key steroidogenic enzyme 21-hydroxylase. A complex interplay of genetic, immunological and environmental factors culminates in symptomatic adrenocortical insufficiency, with symptoms typically developing over months to years. Biochemical evaluation and further targeted investigations must confirm primary adrenal failure and establish the underlying aetiology. The diagnosis of adrenocortical insufficiency will necessitate lifelong glucocorticoid and mineralocorticoid replacement therapy, aiming to emulate physiological patterns of hormone secretion to achieve well-being and good quality of life. Education of patients and healthcare professionals is essential to minimise the risk of a life-threatening adrenal crisis, which must be promptly recognised and aggressively managed when it does occur. This article provides an overview of our current understanding of the natural history and underlying genetic and immunological basis of this condition. Future research may reveal novel therapeutic strategies for patient management. Until then, optimisation of pharmacological intervention and continued emphasis on education and empowerment of patients should underpin the management of individuals with autoimmune Addison's disease.

Autoimmune diseases of the thyroid gland are considered to be the most frequent cause of thyroid gland disorders. Autoimmune thyroid diseases consist of two subgroups: autoimmune thyroiditis (AIT) and Graves' disease. The AIT is the most common human autoimmune disease. Infiltration of the thyroid gland with cytotoxic T‑cells can lead to an initial thyrotoxicosis und during the course to hypothyroidism due to destruction of the thyroid gland. Substitution with Levothyroxine is indicated for manifest hypothyroidism and subclinical hypothyroidism with increased thyroid antibodies with the intention of normalizing the serum thyroid stimulating hormone (TSH). Graves' disease is characterized by the appearance of stimulating TSH receptor antibodies leading to hyperthyroidism. Endocrine ophthalmopathy may also occur. Ablative therapy with radioiodine therapy or thyroidectomy is administered to patients with Graves' disease without remission after at least 1 year of antithyroid drug therapy.

Autoimmune hepatopathies (AIHT) including autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC) and autoimmune cholangitis (AIC), represent an impressive entities in clinical practice. Their pathogenesis is not perfectly elucidated. Several factors are involved in the initiation of hepatic autoimmune and inflammatory phenomena such as genetic predisposition, molecular mimicry and/or abnormalities of T-regulatory lymphocytes. AIHT have a wide spectrum of presentation, ranging from asymptomatic forms to severe acute liver failure. The diagnosis of AIHT is based on the presence of hyperglobulinemia, cytolysis, cholestasis, typical even specific circulating auto-antibodies, distinctive of AIH or PBC, and histological abnormalities as well as necrosis and inflammation. Anti-F actin, anti-LKM1, anti-LC1 antibodies permit to distinguish between AIH type 1 and AIH type 2. Anti-SLA/LP antibodies are rather associated to more severe hepatitis, and particularly useful for the diagnosis of seronegative AIH for other the antibodies. Due to the relevant diagnostic value of anti-M2, anti-Sp100, and anti-gp210 antibodies, the diagnosis of PBC is more affordable than that of PSC and AIC. Based on clinical data, the immunological diagnosis of AIHT takes advantage of the various specialized laboratory techniques including immunofluorescence, immunodot or blot, and the Elisa systems, provided of a closer collaboration between the biologist and the physician.

Folate and vitamin B12 deficiencies have been known to cause megaloblastic anaemia. Since the deficiencies of these two vitamins are very common in Pakistani population, it would be imperative to investigate their role in causing megaloblastic anaemia. The objective of this study was to find out the contribution of folate and vitamin B12 deficiencies in causing megaloblastic anaemia in our patient population. Methods: In this retrospective cohort study, clinical records of 220 patients (101 females and 119 males with an age range of 1 - 80 years) who presented themselves with macrocytic anaemia at the Aga Khan University Hospital were collected. Data pertaining to complete blood count and serum levels of folate and vitamin B12 were analysed. Results: The mean haemoglobin (Hb) level was 6.8 +- 0.2 gm/dl. Sixty-nine percent of the patients had severe anaemia (Hb<8 gm/dl). Mean +- SEM values of haemoglobin, serum folate and serum B12 were not significantly different between males and females (Hb 6.4 +- 0.3 gm/dl vs 6.3 +- 0.3 gm/dl; folate 6.9 +- 0.8 mu g/ml vs 7.8 +- 1 mu g/ml; B12 259 +- 65 mu g/ml vs 225 +- 45 mu g/ml, respectively). Linear regression analysis showed that serum folate was inversely related with the mean corpuscular volume (MCV, p=0.04). Spearman's correlation analysis indicated an inverse mild association between MCV and serum folate (correlation coefficient= -0.18). Folate deficiency was 43.4%, while vitamin B12 deficiency was 78.5% in these patients. Seventy-one percent of folate-deficient patients had vitamin B12 deficiency as well, while 26.1% of patients with B12 deficiency had a co-occurrence of folate deficiency. Conclusion: Vitamin B12 deficiency appears to be the major factor leading to megaloblastic anaemia in our study population. Inadequate dietary intake, over-cooking of our food and poor absorption might be contributing to high prevalence of vitamin B12 deficiency in this population. (author)
