The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions.

A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis. (From Cecil Textbook of Medicine, 19th ed, p848)Erythrocyte Aging: The senescence of RED BLOOD CELLS.

Alcohol interferes with its intermediate metabolism and absorption. Folic acid deficiency may develop in long-term anticonvulsant therapy or with use of oral contraceptives. This deficiency causes anemia, macrocytic anemia, and megaloblastic anemia. It is indistinguishable from vitamin B 12 deficiency in peripheral blood and bone marrow findings, but the neurologic lesions seen in B 12 deficiency do not occur.

Oral treatment with trimethoprim-sulfamethoxazole and zidovudine suppresses murine accessory cell-dependent immune responses. (1/185)

Trimethoprim-sulfamethoxazole (TMP-SMX), commonly used for prophylaxis of Pneumocystis carinii pneumonia (PCP) in AIDS patients, often produces a high incidence of treatment-limiting reactions. We investigated the effect of oral administration of TMP-SMX alone or in combination with the antiretroviral drug zidovudine (ZDV) on hematopoiesis and cellular immunity in BALB/c mice. Daily treatment for 28 days with TMP-SMX (160:800 mg/kg) had no effect on hematopoiesis or the ex vivo proliferative response of splenic T lymphocytes to allogeneic tumor cells (EL-4) or to concanavalin A (ConA), or that of splenic B cells to lipopolysaccharide (LPS). ZDV at 240 mg/kg/day was not immunosuppressive but caused a mild macrocytic anemia. Combined treatment produced severe pancytopenia, a significant drop in splenic cellularity, and a 61% decrease in the percentage of splenic macrophages. The percentage of splenic CD3+ lymphocytes increased 150% in the TMP-SMX + ZDV group, but the ratios of T-cell subsets and the frequency of B cells remained unchanged. Combined drug treatment did not impair the proliferative response of B cells to LPS or that of T cells to EL-4 cells. In concert with the reduction in the percentage of macrophages, the proliferative response of T lymphocytes to ConA decreased significantly. Optimal ConA-induced T-cell proliferation requires the participation of accessory cells (AC) (e.g., macrophages); EL-4 cells are able to function as AC. These data indicate that ZDV synergizes with TMP-SMX, causing severe hematotoxicity and suppressing AC-dependent immune function, and suggest that this therapeutic regimen may contribute to the immune deterioration in AIDS patients.  (+info)

Hereditary hemochromatosis in a patient with congenital dyserythropoietic anemia. (2/185)

Herein is described the case of a young woman presenting with iron overload and macrocytosis. The initial diagnosis was hereditary hemochromatosis. Severe anemia developed after a few phlebotomies, and she was also found to have congenital dyserythropoietic anemia that, though not completely typical, resembled type II. Only genetic testing allowed the definition of the coexistence of the 2 diseases, both responsible for the iron overload. This report points out the need to consider congenital dyserythropoietic anemia in patients with hemochromatosis and unexplained macrocytosis and, conversely, to check for the presence of hereditary hemochromatosis in patients with congenital dyserythropoietic anemia and severe iron overload. To the authors' knowledge, this is the first report of homozygosity for the C282Y mutation of the HFE gene in a patient affected by congenital dyserythropoietic anemia.  (+info)

Erythropoiesis in steel mutant mice: effects of erythropoietin in vitro. (3/185)

Adult SI/SI-d mutant mice have severe macrocytic, normochromic anemia. Moreover these animals are unresponsive to the stimulation of erythropoietin in vivo. By means of a bone marrow cell suspension culture system, the present investigation shows that in adult SI/SI-d marrow, there are cells capable of responding in vitro to erythropoietin in a normal fashion. Moreover, the erythropoietin present in SI/SI-d serum is biologically active in vitro without any prior biochemical modification. These observations support the suggestion that there is a defect in differentiation in the erythroid cell lines of SI/SI-d mice in vivo due to an abnormal hemopoietic microenvironment.  (+info)

Depressed cell-mediated immunity in megaloblastic anemia due to folic acid deficiency. (4/185)

Cell-mediated immunity has been studied in patients with 1) megaloblastic anemia of folic acid deficiency, 2)megaloblastic anemia of pregnancy, or 3) iron-deficiency anemia. Using dinitrochlorobenzene skin tests, phytohemagglutinin-stimulated lymphocyte transformation, and rosette inhibition by antilymphocyte globulin, we have shown that cell-mediated immunity is depressed in megaloblastic anemia due to folate deficiency; this depression was reversed by folate treatment. Cell-mediated immunity was not impaired by iron-deficiency anemia. Suggested interactions between iron deficiency and folate metabolism were not clarified by these studies.  (+info)

Arsenic intoxication as a cause of megaloblastic anemia. (5/185)

We have described a case of chronic arsenic intoxication associated with pancytopenia and megaloblastic erythropoiesis. The patient had the typical laboratory manifestations of effective erythorpoiesis due to a megaloblastic process, including macroovalocytes, mild pancytopenia, low reticulocyte index, increased marrow cellularity with erythroid hyperplasia, and morphologic evidence of megaloblastic maturation in the marrow. The patient's serum folate and vitamin B12 were normal, and the anemia regressed without therapy. Our case suggests that the combination of megaloblastosis with normoblastic or megaloblastic karyorrhexis,should raise the suspicion of arsenic intoxication in the mind of the observer. In addition, arsenic should be added to the list of agents causing a reversible megaloblastic anemia.  (+info)

Unusual megaloblastic anaemia wiht multinucleate erythroblasts: two cases with septicaemia and acute renal failure. (6/185)

The case histories and blood pictures of two patients who had cardiac lesions, septicaemia, and renal failure and terminally developed a leucoerythroblastic anaemia with megloblastic features associated with multinucleate erythroblasts, are described. Though folate deficiency may have made a minor contribution to the blood abnormalities, it is considered that some other disturbance in erythropoiesis was responsible for the bizarre blood and bone marrow changes in these patients. Similar cases reported in the earlier literature are reviewed.  (+info)

Erythrocyte volume distribution in normal and abnormal subjects. (7/185)

Size-frequency distribution curves of erythrocytes were generated with the Coulter Counter in 73 normal subjects and patients. Mean corpuscular volume (MCV) determined by routine calculation and MCV determined by size-frequency distribution were similar in all normal subjects and in patients with a single population of erythrocytes. Some patients with iron-deficiency anemia, folate deficiency, and vitamin B12 deficiency had two discrete erythrocyte populations. Some patients with microcytic anemia were shown to have a population of normocytes in addition to the predominant microcytic population. Reticulocytes and normocytes were identified in two patients recovering from macrocytic anemia. Transfused blood was identified as a separate population in a patient with microcytic anemia. In cases with two erythrocyte populations, the MCV of the principal population, as determined from size-distribution curves, differed from the MCV of the entire erythrocyte pool, as was determined by routine methods. Analysis of sequential erythrocyte size distributions in patients under treatment demonstrated the dynamics of erythrocyte subpopulations. Anisocytosis was quantified and shown to be associated frequently with hospitalized patients.  (+info)

A new hematologic syndrome with a distinct karyotype: the 5 q--chromosome. (8/185)

Five patients, four women and one man, age 32-8- yr, all whites, had refractory anemia with the same abnormal bone marrow karyotype, i.e., a partial deletion of the long arm of the No. 5 chromosome. The hematologic syndrome was practically the same in these five cases. Examination of the blood revealed a moderate to severe, generally macrocytic anemia with slight leukopenia but normal or elevated platelet count. The bone marrow showed a depressed erythroid series and some abnormalities of the granulocytic series with an occasional excess of myeloblasts. Most of the megakaryocytes had a nonlobulated nucleus. These features, as well as cytogenetic, electron microscopic, isotopic, platelet function, and immunologic studies, are described in detail. The relationship of this newly established syndrome to other hematologic diseases is discussed. The syndrome constitutes another example of the association between a specific abnormal chromosome and a distinct hematologic disorder.  (+info)

Macrocytic Anemia symptoms and signs are attributable to the underlying condition that caused the anemia or to the anemia itself, including dyspnea, headache, fatigue, sore tongue, diarrhea and other gastrointestinal symptoms. Other symptoms include certain manifestations including glossitis, tachycardia, flow murmurs, splenomegaly, conjunctival pallor, and other neurological disorders such as ataxia, loss of deep tendon reflexes, particularly ankle reflex, loss of posterior column sensations, and confabulation.. RBCs in macrocytic Anemia appear larger than normal cells on a peripheral blood smear. The MCV (mean cell volume) is typically greater than 100 fL (normal: about 90 fL). When macrocytic changes are evident in the RBCs of the bone marrow as well as in the peripheral blood, the anemia is termed megaloblastic anemia. ...
The term macrocytic is from Greek words meaning "large cell". A macrocytic class of anemia is an anemia (defined as blood with an insufficient concentration of hemoglobin) in which the red blood cells (erythrocytes) are larger than their normal volume. The normal erythrocyte volume in humans is about 80 to 100 femtoliters (fL= 10−15 L). In metric terms the size is given in equivalent cubic micrometers (1 μm3 = 1 fL). The condition of having erythrocytes which (on average) are too large, is called macrocytosis. In contrast, in microcytic anemia, the erythrocytes are smaller than normal. In a macrocytic anemia, the larger red cells are always associated with insufficient numbers of cells and often also insufficient hemoglobin content per cell. Both of these factors work to the opposite effect of larger cell size, to finally result in a total blood hemoglobin concentration that is less than normal (i.e., anemia). Macrocytic anemia is not a disease in the sense of having a single pathology but, ...

The 5q- syndrome is the most distinct of the myelodysplastic syndromes (MDS) and patients with this disorder have a deletion of chromosome 5q [del(5q)] as the sole karyotypic abnormality. Several genes mapping to the commonly deleted region of the 5q- syndrome have been implicated in disease pathogenesis in recent years. Haploinsufficiency of the ribosomal gene RPS14 has been shown to cause the erythroid defect in the 5q- syndrome. Loss of the microRNA genes miR-145 and miR-146a has been associated with the thrombocytosis observed in 5q- syndrome patients. Haploinsufficiency of CSNK1A1 leads to hematopoietic stem cell expansion in mice and may play a role in the initial clonal expansion in patients with 5q- syndrome. Moreover, a subset of patients harbor mutation of the remaining CSNK1A1 allele. Mouse models of the 5q- syndrome, which recapitulate the key features of the human disease, indicate that a p53-dependent mechanism underlies the pathophysiology of this disorder. Importantly, activation of p53

This study showed that vitamin B12 deficiency causes reversible cognitive problems. Could the B12 deficiency be causing the Alzheimers? If yes, then its another reversible cause. In this study, they used cases of very severely low B12 levels. Other studies show that evidence of brain problems from B12 deficiency are seen even at B12 levels of 300, and likely even higher (anything under 209 is sadly still considered normal by some physicians). Biochemical signs of B12 deficiency are seen even at B12 levels over 540. In a study involving 36 patients between the ages of 16 and 80 years of age (32 patients being over the age of 40 years) with low serum B12 or megaloblastic bone marrow or both, a high incidence of cognitive impairment and P3 abnormalities were found in patients that significantly improved by supplementing with vitamin B12.

Megaloblastic anemia happens when your body produces unusually large, structurally abnormal, immature red blood cells (megaloblasts). Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues. Megaloblastic anemia has several different causes - deficiencies of either cobalamin (vitamin B12) or folate (vitamin B9) are the two most common causes.. Megaloblastic anemia usually develops slowly and affected individuals may remain asymptomatic for many years. Symptoms common to anemia usually develop at some point and may include fatigue, paleness of the skin, shortness of breath, lightheadedness, dizziness and a fast or irregular heartbeat. The specific symptoms present in each individual can vary greatly.. ...

Genetics Home Reference : 25 5q minus (5q-) syndrome is a type of bone marrow disorder called myelodysplastic syndrome (MDS). MDS comprises a group of conditions in which immature blood cells fail to develop normally, resulting in too many immature cells and too few normal mature blood cells. In 5q- syndrome, development of red blood cells is particularly affected, leading to a shortage of these cells (anemia). In addition, the red blood cells that are present are unusually large (macrocytic). Although many people with 5q- syndrome have no symptoms related to anemia, especially in the early stages of the condition, some affected individuals develop extreme tiredness (fatigue), weakness, and an abnormally pale appearance (pallor) as the condition worsens. Individuals with 5q- syndrome also have abnormal development of bone marrow cells called megakaryocytes, which produce platelets, the cell fragments involved in blood clotting.

She complained of progressively increasing lethargy, palpitations, and buzzing in the ears over about three months. She had a good, well balanced diet and was not a vegetarian. Apart from thyroxine, she was taking no regular medication. She said her father had had pernicious anaemia. On clinical examination the only clinically significant findings were a mild glossitis and pallor. A full blood count showed a substantial macrocytic anaemia and a mild reduction of the white cell count (figure). The blood film showed mild oval macrocytosis, occasional nucleated red cells, and some hypersegmented neutrophils. An urgent bone marrow examination showed megaloblastic haemopoiesis.. ...
Various inherited and acquired hematopoietic disorders are characterized by macrocytic anemia, in which red blood cells are abnormally large with insufficient hemoglobin, and evidence of dysfunctional erythropoiesis. While multiple etiologies have been implicated for the development of these disorders, many cases of abnormal blood cell production have no discernable cause. Vijay Sankaran and colleagues at Harvard Medical School identified a female with a macrocytic, dyserythropoietic anemia that had been present since childhood. Moreover, the mother and sister of the affected individual also presented with macrocytic anemia, suggesting an underlying genetic cause. Whole exome sequencing of the three affected family members and one unaffected member revealed the presence of a mutation in one allele of the X-chromosomal gene aminolevulinic acid synthase (ALAS2), which encodes an erythroid-specific mitochondrial enzyme required for heme biosynthesis. Enzyme kinetic analysis of WT and mutant ALAS2 ...

Lets not forget about the micronutrients that pumpkin offers, like copper, folate and magnesium. These are nutrients that we need in smaller amounts. Folate plays a role in energy metabolism and also contributes to the health of red blood cells, which help deliver oxygen to the working muscles. A deficiency in folate can lead to macrocytic anemia, where red blood cells dont divide normally. Macrocytic anemia often results in fatigue, since the improper dividing of red blood cells means there are fewer cells to deliver oxygen to muscle tissue. Magnesium is a cofactor in more than 300 reactions in the body, including muscle and nerve function, energy production and muscle contraction. One-quarter cup of pumpkin seeds gives you nearly half of your bodys daily magnesium needs.. Dont underestimate how these nutrients can improve your running. Fall is the perfect time to include pumpkin puree or pumpkin seeds in your meals and snacks. Add some pumpkin seeds to your yogurt, salads or trail mix, ...

Macrocytosis, generally defined as a mean corpuscular volume greater than 100 fL, is frequently encountered when a complete blood count is performed. The most common etiologies are alcoholism, vitamin B12 and folate deficiencies, and medications. History and physical examination, vitamin B12 level, reticulocyte count, and a peripheral smear are helpful in delineating the underlying cause of macrocytosis. When the peripheral smear indicates megaloblastic anemia (demonstrated by macro-ovalocytes and hyper-segmented neutrophils), vitamin B12 or folate deficiency is the most likely cause. When the peripheral smear is non-megaloblastic, the reticulocyte count helps differentiate between drug or alcohol toxicity and hemolysis or hemorrhage. Of other possible etiologies, hypothyroidism, liver disease, and primary bone marrow dysplasias (including myelodysplasia and myeloproliferative disorders) are some of the more common causes.

Perspective article on myelodysplastic syndrome with deltion 5q. In 1974 Herman van den Berghe et al. reported a distinct hematologic disorder associated with acquired deletion of the long arm of chromosome 5 [del(5q)]. This novel nosological entity was described in more detail one year later by Sokal, van den Berghe, and coworkers. Patients with del(5q) had macrocytic anemia with oval macrocytes, normal to slightly reduced white blood cell counts, and normal to elevated platelet counts. With respect to the bone marrow, there was erythroid hypoplasia but the most striking abnormality concerned the megakaryocytes and especially their nuclei, which were generally small, round or oval, and nonlobulated. Until that time, the only specific chromosomal abnormality in hematologic disorders was the Philadelphia chromosome associated with chronic myeloid leukemia. Sokal et al. concluded that del(5q) represented a novel specific chromosomal abnormality associated with refractory anemia, although they ...
If you never knew why your mom told you to eat your vegetables, youre about to find out. Among the many vitamins and nutrients found in vegetables is folate, which is vital for growth. Sometimes known as folic acid, this vitamin helps your body build new cells. This process takes place every day, so dont ever pass on the salad.. The discovery of folate was closely tied to the discovery of vitamin B12. These two vitamins work together in several important biological reactions. A deficiency of either vitamin results in a condition known as megaloblastic, or macrocytic (large-cell), anemia.. In 1930, researcher Lucy Wills and her colleagues reported that yeast contained a substance that could cure macrocytic anemia in pregnant women. But it wasnt until the early 1940s that folate was finally isolated and identified.. Folate functions as a coenzyme during many reactions in the body. It has an important role in making new cells, because it helps form the genetic material DNA (deoxyribonucleic ...

In 1931, Dr. Lucy Wells, a British pathologist, investigated macrocytic anemia in pregnant women living in India. She found that the anemia was most frequent in poorer populations with diets deficient in protein, fruit, and vegetables. She discovered that the anemia was prevented by yeast added to a diet otherwise lacking B vitamins. In 1941, folate was first isolated from spinach and received the name "folic acid." This was the same vitamin that was helpful in reversing anemia in those lab rats in Dr. Wellss study.. In 1943, folic acid was first chemically manufactured by Bob Stokstad (working at Lederle Laboratories American Cyanid Company) in New York. This synthetic form was different than the natural folate found in foods, however, in its chemical structure. So at that point, "folic acid" became used to denote the fully oxidized chemical compound, not present in natural foods.. (Its important to note that now, "folic acid" refers to the synthetic version and "folate" is the natural ...

A 50 year old man was referred to our rheumatology unit with an 18 month history of classic Raynauds phenomenon with episodic digital pain and biphasic (white-blue) colour changes associated with cold exposure. He had noticed that his urine was dark during periods of cold weather. He had a macrocytic anaemia but normal serum levels of vitamin B-12 and folate. There were no additional clinical features to suggest an underlying connective tissue disease, and an autoimmune serology was negative.. Initial laboratory investigations showed a haemoglobin concentration of 107 g/l, mean corpuscular volume of 104.4 fl, bilirubin concentration of 47 µmol/l, and lactate dehydrogenase 695 U/l. Reticulocyte count was raised at 162.4 (normal range 10-100). IgG and IgA levels were normal. IgM concentration was raised at 3.62 g/l (normal range 0.5-2.0 g/l). Infrared thermography at baseline was normal, but delayed rewarming was apparent after local cold exposure, consistent with Raynauds phenomenon (fig ...
Older people have a high risk of vitamin B12 deficiency; this can lead to varying degrees of cognitive and neurological impairment. CBL deficiency may present as macrocytic anemia, subacute combined degeneration of the spinal cord, or as neuropathy, but is often asymptomatic in older people. Less is known about subclinical vitamin B12 deficiency and concurrent neuroconduction and cognitive impairment. A Programme of Complementary Feeding for the Older Population (PACAM) in Chile delivers 2 complementary fortified foods that provide approximately 1.4 μg/day of vitamin B12 (2.4 μg/day elderly RDA). The aim of the present study is to assess whether supplementation with vitamin B12 will improve neuroconduction and cognitive function in older people who have biochemical evidence of vitamin B12 insufficiency in the absence of clinical deficiency. We designed a cluster double-blind placebo-controlled trial involving community dwelling people aged 70-79 living in Santiago, Chile. We randomized 15 clusters

CASE REPORTS The first patient (PMR) is a 17.5-year-old Italian girl who presented megaloblastic anemia at 7.5 months of age. At age 2.5 years, because of the presence of diabetes and sensorineural deafness, she was diagnosed with TRMA syndrome and started treatment with thiamine-HCl, followed very early by benzoyloxymethyl-thiamine (BOM-T). The second patient (PF) is a 16.8-year-old Italian boy born to consanguineous parents. Sensorineural deafness was diagnosed at age 1.5 years, while diabetes with ketoacidosis and megaloblastic anemia were diagnosed at age 3 years. Treatment with thiamine HCl was started immediately after diagnosis and changed to BOM-T 2 months later. Subsequent to the initiation of the vitamin, the two patients did not require insulin for ∼ 7 and 10 years, respectively. Puberty was determinant in deteriorating the metabolic control in these patients, leading to treatment with an oral hypoglycemic agent and finally to a reinstitution of insulin therapy.. ...

The neurological condition triggered by anaesthesia with nitrous oxide involves the cyanocobalamine pathway and is characterised by progressive demyelination and axonal lesions of the peripheral nerves and cervicothoracic spinal cord (posterior and anterolateral columns) giving a peripheral neuropathy and very frequently subacute combined degeneration of the spinal cord. It is possible to show these demyelinating lesions by MRI of the spine, allowing early diagnosis and follow-up. We describe a case of myeloneuropathy with onset a few hours after nitrous oxide anaesthesia in a patient with macrocytic anaemia and possible subclinical vitamin B(12) deficiency and MRI evidence of a lesion of the cervical spinal cord ...
In recent years we have gained great insight into the molecular pathogenesis of the 5q- syndrome, a distinct subtype of myelodysplasia. The demonstration of haploinsufficiency of the ribosomal gene RPS14 (mapping to the commonly deleted region) and the finding that this is the cause of the erythroid defect in the 5qsyndrome represent major advances. A mouse model of the human 5q- syndrome generated by large-scale deletion of the Cd74-Nid67 interval (containing RPS14) further supports a critical role for RPS14 haploinsufficiency. It is widely accepted that ribosomal deficiency results in p53 activation and defective erythropoiesis and the crossing of the 5q- mice with p53 deficient mice ameliorated the erythroid progenitor defect. Emerging data suggests that the p53 activation observed in the mouse model may also apply to the human 5q- syndrome.

Megaloblastic anemia is a condition characterized by the formation of unusually large, abnormal and immature red blood cells called as megaloblasts in the bone marrow.
In contrast, the homocysteine level is elevated only in folate deficiency and is normal in vitamin B12 deficiency." B12 deficiency causes an elevation in homocysteine. In the age of folic acid fortification elevations in homocysteine are much more likely to be caused by B12 deficiency than folic acid deficiency. In the age of folic acid fortification, macrocytosis should always be assumed to be caused by B12 deficiency, not folic acid deficiency. Mandatory fortification of flour products in the US with folic-acid-only corrects the macrocytosis doctors may have seen in the past. A persistent knowledge gap means that many practicing physicians risk missing a B12 deficiency in their patients. B12 deficiency cannot be ruled out by absence of anemia or macrocytosis. It must be checked for directly. Elevated homocysteine is a red flag, especially in a patient with "low-normal" B12 levels. A normal B12 level does not rule out deficiency, and testing of metabolites methylmalonic acid and homocysteine ...
Dr. Roy Gravel, also a co-author of the study and member of the Alberta Childrens Hospital Research Institute says this study provides a tremendous opportunity to look at the prevention of diseases like spina bifida. "The work began as a study of a gene called Mtrr in mice. The goal was to shed light on how a mutation in Mtrr would affect folate metabolism. The multigeneral effect we observed was completely unexpected," says Gravel. The Mtrr gene encodes an enzyme that is key to the metabolism of folic acid and, when mutated, causes similar effects to dietary folic acid deficiency. The researchers found that when either the maternal grandmother or the maternal grandfather had this Mtrr mutation, their genetically normal grandchildren were at risk of a wide spectrum of developmental abnormalities, even if the mutated gene was not inherited through to the next generations. These developmental abnormalities were also seen in the fourth and fifth generations of mice. Through a series of ...

Normocytic Anemias are a categorization of anemias defined as those anemias which display normal-sized erythrocytes (i.e. Normal Mean Corpuscular Volume or MCV) and low reticulocyte counts. In general, normocytic anemias are caused by failure of the bone marrow to conduct proper hematopoiesis; consequently, normocytic anemias typically occur in the context of an overall pancytopenia. Failure of the bone marrow may be due to inherent defects of the marrow itself as in aplastic anemia and the myelodysplastic syndromes, or may be due to exogenous infiltration of the bone marrow by malignant cells or infectious organisms (myelophthisic anemia ...

Erythropoiesis requires rapid and extensive hemoglobin production. Heme activates globin transcription and translation; therefore, heme synthesis must precede globin synthesis. As free heme is a potent inducer of oxidative damage, its levels within cellular compartments require stringent regulation. Mice lacking the heme exporter FLVCR1 have a severe macrocytic anemia; however, the mechanisms that underlie erythropoiesis dysfunction in these animals are unclear. Here, we determined that erythropoiesis failure occurs in these animals at the CFU-E/proerythroblast stage, a point at which the transferrin receptor (CD71) is upregulated, iron is imported, and heme is synthesized - before ample globin is produced. From the CFU-E/proerythroblast (CD71+ Ter119- cells) stage onward, erythroid progenitors exhibited excess heme content, increased cytoplasmic ROS, and increased apoptosis. Reducing heme synthesis in FLVCR1-defient animals via genetic and biochemical approaches improved the anemia, implying ...

Celiac disease, and, more generally, gluten intolerance, is a growing problem worldwide, but especially in North America and Europe, where an estimated 5% of the population now suffers from it. Symptoms include nausea, diarrhea, skin rashes, macrocytic anemia and depression. It is a multifactorial disease associated with numerous nutritional deficiencies as well as reproductive issues and increased risk to thyroid disease, kidney failure and cancer. Here, we propose that glyphosate, the active ingredient in the herbicide, Roundup®, is the most important causal factor in this epidemic. Fish exposed to glyphosate develop digestive problems that are reminiscent of celiac disease. Celiac disease is associated with imbalances in gut bacteria that can be fully explained by the known effects of glyphosate on gut bacteria. Characteristics of celiac disease point to impairment in many cytochrome P450 enzymes, which are involved with detoxifying environmental toxins, activating vitamin D3, catabolizing ...

A 66-year-old African American woman with lifelong anemia and a positive family history of anemia came to the emergency room with abdominal pain. Her numerous previous medical problems included intermittent bone pains, infections, and chest pains. When seen, she was writhing in pain and asking for narcotics. Her physical exam showed slight fever, some scleral icterus, and a tender abdomen with normal bowel sounds.. The clinical picture was thought to be consistent with sickle cell painful crisis, but the white blood cell count was 3.7 × 109/L; granulocyte count, 1.0 × 109/L; and platelet count, 110 × 109/L. In retrospect, granulocytopenia and thrombocytopenia had been evolving over the past several months. A peripheral smear showed sickle forms and targets. Immature cells were also present, some of which contained Auer rods (see above). The bone marrow was hypocellular with megaloblastic changes, but with 15 % leukemic cells. Rather than another diagnosis of painful crisis, she had refractory ...
Here, we show that Cdk5rap2 is mutated in the Hertwigs anemia mouse, and we demonstrate that Cdk5rap2 is essential for normal progenitor proliferation and survival in the cerebral cortex. Cdk5rap2an/an animals have smaller cerebral cortices that result from an overall reduction of the neuronal layers caused by a decrease in progenitor numbers. Increases in both cell death and premature cell cycle exit reduce the cortical precursor population. Moreover, the decrease of neuronal progenitors in Cdk5rap2an/an animals correlates, paradoxically, with an increased mitotic index, suggesting delays in mitotic progression. We found altered mitotic orientation as well as increased abnormal mitotic figures, with aneupolar spindles, implicating essential roles for Cdk5rap2 in spindle and centrosome function during neurogenesis. These data suggest that CDK5RAP2 mutations in humans could cause microcephaly by mechanisms that include not only mitotic arrest and cell death, but also may include defects in cell ...

Background: Additional folic acid treatment appears to have a neutral effect on reducing vascular risk in countries that mandate fortification of food with folic acid (e.g. US and Canada). However, it is uncertain whether folic acid therapy reduces stroke risk in countries without folic acid food fortification.. Objective: To comprehensively evaluate the efficacy of folic acid therapy on stroke prevention in countries without folic acid food fortification.. Methods: Pubmed, EMBASE, and Clinicaltrials.gov from January 1966 to August 2015 were searched to identify relevant studies. Relative risk (RR) with 95% CI was used as a measure of the association between folic acid supplementation and risk of stroke, after pooling data across trials in a random-effects model.. Results: The search identified 14 randomized controlled trials involving treatment with folic acid that had enrolled 71,334 participants, all of which stroke was reported as an outcome measure. Across all trials, folic acid therapy vs. ...
A method for the measurement of serum folic acid activity is described, which is a modification of previous methods.. The material in serum with activity for L. casei is made up of a stable and a labile component. The amount of stable component in normal subjects and patients with megaloblastic anaemia is similar. The amount of labile component varies. In patients with folic acid deficiency none is present; in normal subjects it constitutes between 65 and 94% of the total serum L. casei activity. The labile component appears to be an index of folic acid metabolism, and the assay of total serum L. casei activity is therefore a valuable method for differentiating patients requiring treatment with folic acid from normal subjects and patients with primary vitamin B12 deficiency. Normal subjects had serum folic acid levels from 5·9 to 21·0 mμg./ml. (mean 9·9 mμg./ml. ± 0·3 mμg./ml. S.E.). In patients with megaloblastic anaemia requiring treatment with folic acid, other than megaloblastic ...
Folic acid, folate, or vitamin B-9, is a water-soluble vitamin. It plays an important part in cell division and in making cells in the blood-forming organs and bone marrow. It also plays a role in the development of the fetal spinal cord during pregnancy. Like the other B vitamins, folic acid plays an important role in energy production. The body converts folic acid to tetrahydrofolic acid. Tetrahydrofolic acid plays an important part in cell division. Its involved in nucleic acid (DNA and RNA) synthesis. Folic acid deficiency causes larger-than-normal red blood cells and other abnormalities in white and red blood cells. This is called macrocytic anemia. Research suggests that folic acid supplements can reduce the incidence of neural tube defects (spina bifida) in newborn infants by up to 50%. For this reason, the National Institutes of Health and Centers for Disease Control and Prevention recommend that women of childbearing age take a minimum of 400 micrograms (mcg) of folic acid per day. To ...
Women of childbearing age, people who abuse alcohol, anyone taking anti-convulsants or other medications that interfere with the action of folate or folic acid, individuals diagnosed with anemia from folate or folic acid deficiency, and individuals with malabsorption, liver disease, or who are receiving kidney dialysis treatment may benefit from a folic acid supplement. Folic acid is very important for all women who may become pregnant. Adequate folate and folic acid intake during the periconceptual period, the time just before and just after a woman becomes pregnant, protects against a number of congenital malformations including neural tube defects21. Neural tube defects result in malformations of the spine (spina bifida), skull, and brain (anencephaly)10. The risk of neural tube defects is significantly reduced when supplemental folic acid is consumed in addition to a healthful diet prior to and during the first month following conception5, 22, 23. Women who could become pregnant are advised ...

Cobalamin is a complex organic molecule containing a tetrapyrole corrin ring that is similar in structure to heme but that has a divalent cobalt atom in its center instead of an iron atom. Like heme iron, this cobalt atom binds to two ligands. One is a benzimidazole nucleotide, whereas the other can be either a methyl group (found in methylcobalamin) or an adenosyl group (found in adenosylcobalamin). Cobalamin is present in all foods of animal origin including meat, fish, and dairy products. Food cobalamin is tightly bound to proteins. Following ingestion, some cobalamin in food is transferred to human haptocorrin in saliva. As depicted in Figure 6-1, the low pH of the gastric juice facilitates efficient release and transfer of the remaining food cobalamin to haptocorrin. After transit to the duodenum, the increase in pH enables the transfer of cobalamin from haptocorrin to intrinsic factor, a transport protein secreted by gastric parietal cells. The cobalamin-intrinsic factor complex resists ...
The clinical and haematological features of an unusual case of congenital dyserythropoietic anaemia are described. There was a pronounced haemolytic component to the anaemia, with a mean cell life of five days, and a remarkable response to splenectomy. Measurement of the incorporation of 15N glycine into the haem of circulating red cells and into bilirubin showed that haem turnover due to ineffective erythropoiesis was increased 45 times compared with a control group (11.63 mg/kg/day, NR = 0.26 + 0-10) and represented 51% of total erythroid haem turnover.. ...
The Online Mendelian Inheritance in Man (OMIM) compendium of human genes and genetic phenotypes includes three types of congenital dyserythropoietic anemia as reported in Table 1. A comprehensive overview of these disorders has been published recently.1. Congenital dyserythropoietic anemia type II is the most common of these inherited disorders. Typical morphological abnormalities of this condition are shown in Figure 1: these abnormalities clearly indicate that incomplete cytokinesis is one of the key features of erythroid cells in this condition.. More than 30 years ago, we investigated the pathophysiology of anemia in patients with congenital dyserythropoietic anemia type II in studies of iron kinetics.2 A wide variation in effectiveness of erythroid activity was observed, and a significant inverse relationship was found between ineffective erythropoiesis and peripheral hemolysis. In 4 patients with prominent peripheral hemolysis, splenectomy was carried out. Marked improvement in their ...

Neural tube defects (NTD) are among the most common birth defects and the leading cause of infant mortality. NTDs occur when the neural tube fails to close during early fetal development. The two most common types of NTD are spina bifida and anencephaly. NTDs result in lifelong complications like musculoskeletal deformities and loss of strength. The etiology of NTDs is complex and involves still unclear environmental and genetic factors. However, one of the well-established risk factors of NTDs is folic acid deficiency. The prevalence of NTDs can be lowered by an adequate intake of folic acid in the periconceptual period. In 1996, the Food and Drug Administration mandated that 140 micrograms of folic acid be added to 100 grams of bleached grain products with the goal of reducing the prevalence of NTDs. In the years following this fortification mandate, studies have shown that blood folate levels have more than doubled on average, that there are demographic and socioeconomic disparities in blood folate
