Anemia, Megaloblastic: A disorder characterized by the presence of ANEMIA, abnormally large red blood cells (megalocytes or macrocytes), and MEGALOBLASTS.Anemia, Macrocytic: Anemia characterized by larger than normal erythrocytes, increased mean corpuscular volume (MCV) and increased mean corpuscular hemoglobin (MCH).Megaloblasts: Red blood cell precursors, corresponding to ERYTHROBLASTS, that are larger than normal, usually resulting from a FOLIC ACID DEFICIENCY or VITAMIN B 12 DEFICIENCY.Anemia: A reduction in the number of circulating ERYTHROCYTES or in the quantity of HEMOGLOBIN.Vitamin B 12 Deficiency: A nutritional condition produced by a deficiency of VITAMIN B 12 in the diet, characterized by megaloblastic anemia. Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. 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)Anemia, Pernicious: A megaloblastic anemia occurring in children but more commonly in later life, characterized by histamine-fast achlorhydria, in which the laboratory and clinical manifestations are based on malabsorption of vitamin B 12 due to a failure of the gastric mucosa to secrete adequate and potent intrinsic factor. (Dorland, 27th ed)Folic Acid Deficiency: A nutritional condition produced by a deficiency of FOLIC ACID in the diet. Many plant and animal tissues contain folic acid, abundant in green leafy vegetables, yeast, liver, and mushrooms but destroyed by long-term cooking. 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. (Merck Manual, 16th ed)Vitamin B 12: A cobalt-containing coordination compound produced by intestinal micro-organisms and found also in soil and water. Higher plants do not concentrate vitamin B 12 from the soil and so are a poor source of the substance as compared with animal tissues. INTRINSIC FACTOR is important for the assimilation of vitamin B 12.FIGLU Test: A urine test for formiminoglutamic acid, an intermediate metabolite in L-histidine catabolism in the conversion of L-histidine to L-glutamic acid. It may be an indicator of vitamin B12 or folic acid deficiency or liver disease.Thiamine: 3-((4-Amino-2-methyl-5-pyrimidinyl)methyl)-5-(2- hydroxyethyl)-4-methylthiazolium chloride.Hydroxocobalamin: Injectable form of VITAMIN B 12 that has been used therapeutically to treat VITAMIN B 12 DEFICIENCY.Intrinsic Factor: A glycoprotein secreted by the cells of the GASTRIC GLANDS that is required for the absorption of VITAMIN B 12 (cyanocobalamin). Deficiency of intrinsic factor leads to VITAMIN B 12 DEFICIENCY and ANEMIA, PERNICIOUS.Anemia, Hypochromic: Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. 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. (Stedman, 25th ed; from Miale, Laboratory Medicine: Hematology, 6th ed, p393)Folic Acid: A member of the vitamin B family that stimulates the hematopoietic system. It is present in the liver and kidney and is found in mushrooms, spinach, yeast, green leaves, and grasses (POACEAE). Folic acid is used in the treatment and prevention of folate deficiencies and megaloblastic anemia.Deoxyuridine: 2'-Deoxyuridine. An antimetabolite that is converted to deoxyuridine triphosphate during DNA synthesis. Laboratory suppression of deoxyuridine is used to diagnose megaloblastic anemias due to vitamin B12 and folate deficiencies.Anemia, Aplastic: A form of anemia in which the bone marrow fails to produce adequate numbers of peripheral blood elements.Pregnancy Complications, Hematologic: The co-occurrence of pregnancy and a blood disease (HEMATOLOGIC DISEASES) which involves BLOOD CELLS or COAGULATION FACTORS. The hematologic disease may precede or follow FERTILIZATION and it may or may not have a deleterious effect on the pregnant woman or FETUS.Bone Marrow Examination: Removal of bone marrow and evaluation of its histologic picture.Anemia, Hemolytic: A condition of inadequate circulating red blood cells (ANEMIA) or insufficient HEMOGLOBIN due to premature destruction of red blood cells (ERYTHROCYTES).Homocystinuria: Autosomal recessive inborn error of methionine metabolism usually caused by a deficiency of CYSTATHIONINE BETA-SYNTHASE and associated with elevations of homocysteine in plasma and urine. Clinical features include a tall slender habitus, SCOLIOSIS, arachnodactyly, MUSCLE WEAKNESS, genu varus, thin blond hair, malar flush, lens dislocations, an increased incidence of MENTAL RETARDATION, and a tendency to develop fibrosis of arteries, frequently complicated by CEREBROVASCULAR ACCIDENTS and MYOCARDIAL INFARCTION. (From Adams et al., Principles of Neurology, 6th ed, p979)Erythrocytes, Abnormal: Oxygen-carrying RED BLOOD CELLS in mammalian blood that are abnormal in structure or function.Neurologic Manifestations: Clinical signs and symptoms caused by nervous system injury or dysfunction.5-Methyltetrahydrofolate-Homocysteine S-Methyltransferase: An enzyme that catalyzes the formation of methionine by transfer of a methyl group from 5-methyltetrahydrofolate to homocysteine. It requires a cobamide coenzyme. The enzyme can act on mono- or triglutamate derivatives. EC 2.1.1.13.Malabsorption Syndromes: General term for a group of MALNUTRITION syndromes caused by failure of normal INTESTINAL ABSORPTION of nutrients.Vitamin B Complex: A group of water-soluble vitamins, some of which are COENZYMES.Pancytopenia: Deficiency of all three cell elements of the blood, erythrocytes, leukocytes and platelets.Schilling Test: A diagnostic test in which vitamin B12 is tagged with radioactive cobalt, taken orally, and gastrointestinal absorption is determined via measurement of the amount of radioactivity in a 24-hour urine collection.Diphyllobothriasis: Infection with tapeworms of the genus Diphyllobothrium.Erythropoiesis: The production of red blood cells (ERYTHROCYTES). In humans, erythrocytes are produced by the YOLK SAC in the first trimester; by the liver in the second trimester; by the BONE MARROW in the third trimester and after birth. In normal individuals, the erythrocyte count in the peripheral blood remains relatively constant implying a balance between the rate of erythrocyte production and rate of destruction.Anemia, Hemolytic, Autoimmune: Acquired hemolytic anemia due to the presence of AUTOANTIBODIES which agglutinate or lyse the patient's own RED BLOOD CELLS.Euglena: A genus of EUKARYOTES, in the phylum EUGLENIDA, found mostly in stagnant water. Characteristics include a pellicle usually marked by spiral or longitudinal striations.Transcobalamins: A group of carrier proteins which bind with VITAMIN B12 in the BLOOD and aid in its transport. Transcobalamin I migrates electrophoretically as a beta-globulin, while transcobalamins II and III migrate as alpha-globulins.Bone Marrow: The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.Erythrocyte Count: The number of RED BLOOD CELLS per unit volume in a sample of venous BLOOD.Clinical Enzyme Tests: Analyses for a specific enzyme activity, or of the level of a specific enzyme that is used to assess health and disease risk, for early detection of disease or disease prediction, diagnosis, and change in disease status.Cytosine NucleotidesHearing Loss, Sensorineural: Hearing loss resulting from damage to the COCHLEA and the sensorineural elements which lie internally beyond the oval and round windows. These elements include the AUDITORY NERVE and its connections in the BRAINSTEM.Methylmalonic Acid: A malonic acid derivative which is a vital intermediate in the metabolism of fat and protein. Abnormalities in methylmalonic acid metabolism lead to methylmalonic aciduria. This metabolic disease is attributed to a block in the enzymatic conversion of methylmalonyl CoA to succinyl CoA.Blood Group Antigens: Sets of cell surface antigens located on BLOOD CELLS. They are usually membrane GLYCOPROTEINS or GLYCOLIPIDS that are antigenically distinguished by their carbohydrate moieties.Anemia, Sideroblastic: Anemia characterized by the presence of erythroblasts containing excessive deposits of iron in the marrow.Erythrocytes: Red blood cells. Mature erythrocytes are non-nucleated, biconcave disks containing HEMOGLOBIN whose function is to transport OXYGEN.Infectious Anemia Virus, Equine: A species of LENTIVIRUS, subgenus equine lentiviruses (LENTIVIRUSES, EQUINE), causing acute and chronic infection in horses. It is transmitted mechanically by biting flies, mosquitoes, and midges, and iatrogenically through unsterilized equipment.

(From Dorland, 28th ed, p1154)Hemoglobins: The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates. The number of globin subunits in the hemoglobin quaternary structure differs between species. Structures range from monomeric to a variety of multimeric arrangements.XyloseAnemia, Refractory: A severe sometimes chronic anemia, usually macrocytic in type, that does not respond to ordinary antianemic therapy.

Endemic tropical sprue in Rhodesia. (1/130)

The existence of tropical sprue in Africa is controversial. In this paper we present 31 cases seen in Rhodesia over a 15 month period. They have the clinical features, small intestinal morphology, malabsorption pattern, and treatment response of tropical sprue. Other causes of malabsorption, and primary malnutrition, have been excluded. The severity of the clinical state and intestinal malabsorption distinguish these patients from those we have described with tropical enteropathy. The previous work on tropical sprue in Africa is reviewed and it is apparent that, when it has been adequately looked for, it has been found. It is clear that the question of tropical sprue in Africa must be re-examined and that it existence may have hitherto been concealed by the assumption that primary malnutrition is responsible for the high prevalence of deficiency states.  (+info)

Defective high-affinity thiamine transporter leads to cell death in thiamine-responsive megaloblastic anemia syndrome fibroblasts. (2/130)

We have investigated the cellular pathology of the syndrome called thiamine-responsive megaloblastic anemia (TRMA) with diabetes and deafness. Cultured diploid fibroblasts were grown in thiamine-free medium and dialyzed serum. Normal fibroblasts survived indefinitely without supplemental thiamine, whereas patient cells died in 5-14 days (mean 9.5 days), and heterozygous cells survived for more than 30 days. TRMA fibroblasts were rescued from death with 10-30 nM thiamine (in the range of normal plasma thiamine concentrations). Positive terminal deoxynucleotide transferase-mediated dUTP nick end-labeling (TUNEL) staining suggested that cell death was due to apoptosis. We assessed cellular uptake of [3H]thiamine at submicromolar concentrations. Normal fibroblasts exhibited saturable, high-affinity thiamine uptake (Km 400-550 nM; Vmax 11 pmol/min/10(6) cells) in addition to a low-affinity unsaturable component. Mutant cells lacked detectable high-affinity uptake. At 30 nM thiamine, the rate of uptake of thiamine by TRMA fibroblasts was 10-fold less than that of wild-type, and cells from obligate heterozygotes had an intermediate phenotype. Transfection of TRMA fibroblasts with the yeast thiamine transporter gene THI10 prevented cell death when cells were grown in the absence of supplemental thiamine. We therefore propose that the primary abnormality in TRMA is absence of a high-affinity thiamine transporter and that low intracellular thiamine concentrations in the mutant cells cause biochemical abnormalities that lead to apoptotic cell death.  (+info)

Molecular basis for methionine synthase reductase deficiency in patients belonging to the cblE complementation group of disorders in folate/cobalamin metabolism. (3/130)

Methionine synthase reductase (MSR) deficiency is an autosomal recessive disorder of folate/cobalamin metabolism leading to hyperhomocysteinemia, hypo- methioninemia and megaloblastic anemia. Deficiency in MSR activity occurs as the result of a defect in the MSR enzyme, which is required for the reductive activation of methionine synthase (MS). MS itself is responsible for the folate/cobalamin-dependent conversion of homo- cysteine to methionine. We have recently cloned the cDNA corresponding to the MSR protein, a novel member of the ferredoxin-NADP(+)reductase (FNR) family of electron transferases. We have used RT-PCR, heteroduplex, single-strand conformation poly- morphism (SSCP) and DNA sequence analyses to reveal 11 mutations in eight patients from seven families belonging to the cblE complementation group of patients of cobalamin metabolism that is defective in the MSR protein. The mutations include splicing defects leading to large insertions or deletions, as well as a number of smaller deletions and point mutations. Apart from an intronic substitution found in two unrelated patients, the mutations appear singular among individuals. Of the eleven, three are nonsense mutations, allowing for the identification of two patients for whom little if any MSR protein should be produced. The remaining eight involve point mutations or in-frame disruptions of the coding sequence and are distributed throughout the coding region, including proposed FMN, FAD and NADPH binding sites. These data demonstrate a unique requirement for MSR in the reductive activation of MS.  (+info)

The pattern of severe protein-calorie malnutrition in Sudanese children attending a large hospital in The Sudan. (4/130)

One hundred fifty patients suffering from severe protein-calorie malnutrition, admitted in 1 month to the Pediatric wards of Wad Medani Hospital, Sudan, were classified according to the Wellcome classification. Marasmus was the prevailing type. It was common in the 2nd year of life, while kwashiorkor occurred mainly under the age of 12 months. Anthropometric measurements showed that kwashiorkor was an acute disease while marasmus and marasmic kwashiorkor were more chronic. The triceps skinfold was unexpectedly low in kwashiorkor. Of the simple measurements and ratios used for assessing the nutritional status, the head/chest ratio applied ot children over 1 year was not found to be reliable and the weight for head circumference correlated poorly with deficits in other variables. Non of the major clinical features was found to be pathognomonic of any type of severe protein-calorie malnutrition. Megaloblastic anemia was common.  (+info)

Cubilin P1297L mutation associated with hereditary megaloblastic anemia 1 causes impaired recognition of intrinsic factor-vitamin B(12) by cubilin. (5/130)

Megaloblastic anemia 1 (MGA1) is an autosomal recessive disorder caused by the selective intestinal malabsorption of intrinsic factor (IF) and vitamin B(12)/cobalamin (Cbl) in complex. Most Finnish patients with MGA1 carry the disease-specific P1297L mutation (FM1) in the IF-B(12) receptor, cubilin. By site-directed mutagenesis, mammalian expression, and functional comparison of the purified wild-type and FM1 mutant forms of the IF-Cbl-binding cubilin region (CUB domains 5-8, amino acid 928-1386), we have investigated the functional implications of the P1297L mutation. Surface plasmon resonance analysis revealed that the P1297L substitution specifically increases the K(d) for IF-Cbl binding several-fold, largely by decreasing the association rate constant. In agreement with the binding data, the wild-type protein, but not the FM1 mutant protein, potently inhibits 37 degrees C uptake of iodine 125-IF-Cbl in cubilin-expressing epithelial cells. In conclusion, the data presented show a substantial loss in affinity of the FM1 mutant form of the IF-Cbl binding region of cubilin. This now explains the malabsorption of Cbl and Cbl-dependent anemia in MGA1 patients with the FM1 mutation. (Blood. 2000;96:405-409)  (+info)

Oral contraceptive hormones, folate metabolism, and the cervical epithelium. (6/130)

The currently available evidence concerning disorders of folate metabolism in women taking oral contraceptives has been reviewed. A disturbance in folate balance serious enough to cause symptoms (i.e., megaloblastic anemia) occurs very rarely. In some series, but not in others, serum and/or red cell folate concentrations have been reduced in oral contraceptive users. It is doubtful whether sex steroids affect polyglutamate folate absorption. About 20 percent of women taking contraceptive hormones manifest mild megaloblastic changes on Papanicolaou smears of the cervicovaginal epithelium which disappear after folic acid therapy. The current evidence, however, would not indicate that any significant benefit would ensue from routine folate supplementation in women on oral contraceptives.  (+info)

A novel mutation in the thiamine responsive megaloblastic anaemia gene SLC19A2 in a patient with deficiency of respiratory chain complex I. (7/130)

The thiamine transporter gene SLC19A2 was recently found to be mutated in thiamine responsive megaloblastic anaemia with diabetes and deafness (TRMA, Rogers syndrome), an early onset autosomal recessive disorder. We now report a novel G1074A transition mutation in exon 4 of the SLC19A2 gene, predicting a Trp358 to ter change, in a girl with consanguineous parents. In addition to the typical triad of Rogers syndrome, the girl presented with short stature, hepatosplenomegaly, retinal degeneration, and a brain MRI lesion. Both muscle and skin biopsies were obtained before high dose thiamine supplementation. While no mitochondrial abnormalities were seen on morphological examination of muscle, biochemical analysis showed a severe deficiency of pyruvate dehydrogenase and complex I of the respiratory chain. In the patient's fibroblasts, the supplementation with high doses of thiamine resulted in restoration of complex I activity. In conclusion, we provide evidence that thiamine deficiency affects complex I activity. The clinical features of TRMA, resembling in part those found in typical mitochondrial disorders with complex I deficiency, may be caused by a secondary defect in mitochondrial energy production.  (+info)

Apoptosis in megaloblastic anemia occurs during DNA synthesis by a p53-independent, nucleoside-reversible mechanism. (8/130)

Deficiency of folate or vitamin B(12) (cobalamin) causes megaloblastic anemia, a disease characterized by pancytopenia due to the excessive apoptosis of hematopoietic progenitor cells. Clinical and experimental studies of megaloblastic anemia have demonstrated an impairment of DNA synthesis and repair in hematopoietic cells that is manifested by an increased percentage of cells in the DNA synthesis phase (S phase) of the cell cycle, compared with normal hematopoietic cells. Both folate and cobalamin are required for normal de novo synthesis of thymidylate and purines. However, previous studies of impaired DNA synthesis and repair in megaloblastic anemia have concerned mainly the decreased intracellular levels of thymidylate and its effects on nucleotide pools and misincorporation of uracil into DNA. An in vitro model of folate-deficient erythropoiesis was used to study the relationship between the S-phase accumulation and apoptosis in megaloblastic anemia. The results indicate that folate-deficient erythroblasts accumulate in and undergo apoptosis in the S phase when compared with control erythroblasts. Both the S-phase accumulation and the apoptosis were induced by folate deficiency in erythroblasts from p53 null mice. The complete reversal of the S-phase accumulation and apoptosis in folate-deficient erythroblasts required the exogenous provision of specific purines or purine nucleosides as well as thymidine. These results indicate that decreased de novo synthesis of purines plays as important a role as decreased de novo synthesis of thymidylate in the pathogenesis of megaloblastic anemia.  (+info)

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.. ...

SUMMARY. Megaloblastic anemia and hypothyroidism, coexisting in relapse simultaneously, were documented in eight women; five patients had primary myxedema; two had secondary myxedema; and one had pituitary insufficiency. The diagnosis of pernicious anemia was excluded by the demonstration of an acidic gastric juice after betazole (Histalog®) stimulation in all eight, quantitatively normal gastric intrinsic factor concentrations in seven, and normal Schilling tests in two. The serum vitamin B12 concentrations were normal (seven patients) or diagnostically indeterminate (one patient) effectively excluding vitamin B12 deficiency as a cause of the megaloblastic anemia. Serum folate levels were subnormal in seven patients and diagnostically indeterminate in one; red cell folate concentrations were subnormal in three and normal in five. Five patients treated with 100 µg/day of oral pteroylglutamic acid in addition to undergoing thyroid replacement achieved complete hematologic remissions within 2 ...

Anemia is a problem in which there are not enough red blood cells or hemoglobin. Hemoglobin is the part of red blood cells that carries oxygen throughout the body. In megaloblastic anemia, the bone marrow, where the cells are formed, makes fewer cells. And the cells that are formed dont live as long as normal.

Vitamin B12 requires an intrinsic factor (a protein secreted by the stomach) to be absorbed. If there is a deficit of its absorption caused by a gastric involvement (usually 90% of cases is autoimmune), it can cause a decrease in the manufacture of intrinsic factor and vitamin B12 is not properly absorbed even when ingested in the necessary amounts. This malabsorption leads to a type of anemia called pernicious anemia.. Pernicious anemia is another type of megaloblastic anemia. It does not appear as a result of a deficit intake of vitamin B12, but the deficit is produced because an autoimmune disorder.. In contrast, megaloblastic anemia is caused by shortage of intake or absorption of two different vitamins, vitamin B9 or folic acid and / or vitamin B12, either one, the other or both.. Another type of anemia, macrocytic normochromic anemia,can be caused by a deficiency of vitamin B12, due to the combined action of abuse of alcohol intake.. In addition, cyanocobalamin or vitamin B12 is also ...
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.. ...

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 ...

Dihydrofolate reductase (DHFR) is a critical enzyme in folate metabolism and an important target of antineoplastic, antimicrobial, and antiinflammatory drugs. We describe three individuals from two families with a recessive inborn error of metabolism, characterized by megaloblastic anemia and/or pancytopenia, severe cerebral folate deficiency, and cerebral tetrahydrobiopterin deficiency due to a germline missense mutation in DHFR, resulting in profound enzyme deficiency. We show that cerebral folate levels, anemia, and pancytopenia of DHFR deficiency can be corrected by treatment with folinic acid. The characterization of this disorder provides evidence for the link between DHFR and metabolism of cerebral tetrahydrobiopterin, which is required for the formation of dopamine, serotonin, and norepinephrine and for the hydroxylation of aromatic amino acids. Moreover, this relationship provides insight into the role of folates in neurological conditions, including depression, Alzheimer disease, and ...
Causes Of Vitamin B12 Deficiency. The daily requirement of vitamin B12 is 1-2 micrograms. About 5-7 micrograms of vitamin B12 is present in most types of western diet; however, many people do not eat enough of the right foods. The absorption of vitamin B12 is a complex process and the production of intrinsic acids within the stomach play a very significant role. Vitamin B12 deficiency can cause malfunction in some organs of the body.A deficiency of this vitamin can also cause some diseases, such as Megaloblastic anemia. Vitamin B12 deficiency is also known to be the cause of anemia macrocytosis. This type of anemia will result in a low white blood cell and platelet count. Vitamin B12 deficiency can also cause the irreversible death of nerve cells.. Visible Symptoms of Vitamin B12 ...

The management of specific forms of anaemia is described in detail in subsequent chapters. However, a few principles can be outlined here. In general, a cause should always be sought before treatment is instituted. There is no place whatever for treating anaemia blind with multihaematinic preparations. As mentioned above, most cases of iron-deficiency anaemia require further investigation for a source of blood loss. If there is a clear-cut history of poor diet, multiple pregnancies, or obvious uterine bleeding, it is reasonable to start iron therapy and observe the haemoglobin level both during the period of treatment and for some months after iron therapy has been stopped. A rise in the haemoglobin level of approximately 1 g/dl per week indicates a full haematological response. For the megaloblastic anaemias it is quite reasonable to start treatment with vitamin B12 and folic acid once a diagnosis has been established and blood samples have been obtained for serum folate and vitamin B12 ...
Folate deficiency is the lack of folic acid in the blood. Folic acid is a B vitamin needed to make normal red blood cells. Low levels can cause megaloblastic anemia.

Vitamin B12 is an important factor in the metabolism of the body, including the successful function of brain, blood cells, nerves, and many other aspects of the body. Low levels of vitamin B12 are associated with a condition known as megaloblastic anemia, where red blood cells are abnormally enlarged. A deficiency of Vitamin B12 can actually produce mental illnesses such as significant dementia, disturbance of mood and psychoses. Other signs of B12 deficiency include ataxia, which products unsteady, shaky movements, weak muscles, spastic muscles, severe incontinence, low blood pressure ("hypotension") and debilitating problems with vision. B12 is often used to help with loss of memory or reduction of memory ability, progressive Alzheimers disease, mood swings and lowered mood, a lack of energy, trouble with concentration, a compromised immune system and the effects of aging. It is known to assist in lowering homocysteine levels which may lead to heart disease, restoring male fertility, reducing ...

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 ...

Imerslund-Grasbeck syndrome, also known as selective intestinal malabsorption of vitamin B12, is a rare autosomal recessive disorder characterized by vitamin B12 deficiency commonly resulting in megaloblastic anemia, which is responsive to parenteral vitamin B12 therapy and appears in childhood. Other manifestations include failure to thrive and grow, infections and neurological damage. Mild proteinuria (with no signs of kidney disease) is present in about half of the patients, and sometimes with anatomical anomalies in the urinary tract. The syndrome was first described in Finland and Norway where the prevalence is about 1:200,000.
Vitamin B12 (cobalamin) deficiency is prevalent worldwide and causes megaloblastic anemia and neurologic deficits. While the anemia can be treated, the neurologic deficits can become refractive to treatment as the disease progresses. Therefore, timely intervention is critical for a favorable outcome. Moreover, the metabolic basis for the neuro-pathologic changes and the role of cobalamin deficiency in the pathology still remains unexplained. Using a transcobalamin receptor / CD320 knockout mouse that lacks the receptor for cellular uptake of transcobalamin bound cobalamin, we aimed to determine whether cobalamin deficiency in the central nervous system produced functional neurologic deficits in the mouse that would parallel those observed in humans ...
Full blood count, Reticulocyte count. Blood film.. The diagnosis is established by Bone marrow biopsy, aspirate and trephine, which are generally indicated unless the pancytopenia is a predictable effect of drugs and/or irradiation (specialist input recommended).. Aplastic anaemia is classified into mild, moderate and severe based on the bone marrow cellularity and degree of cytopenias.. The differential diagnosis includes other congenital and acquired forms of bone marrow failure (including Acute leukaemia, Myelodysplastic syndromes and marrow replacement with fibrosis or tumour), Megaloblastic anaemia and Paroxysmal nocturnal haemoglobinuria (PNH). The FBC and Bone marrow biopsy results will mostly be able to differentiate these from aplastic anaemia, however hypoplastic MDS can be difficult to distinguish, and aplastic anaemia and PNH can occur together..

Cubilin is a protein that in humans is encoded by the CUBN gene. Cubilin (CUBN) acts as a receptor for intrinsic factor-vitamin B12 complexes. The role of receptor is supported by the presence of 27 CUB domains. Cubilin shows a restricted mode of expression according to protein profiling and transcriptomics analyses, and is essentially only present in the kidneys and small intestine. Mutations in CUBN may play a role in autosomal recessive megaloblastic anemia. A complex of amnionless and cubilin forms the cubam receptor. It can be found in the proximal tubule forming part complexes with megalin; the function of these complexes is reabsorptive and can be inhibited by sodium maleate. Cubilin is a potential diagnostic and prognostic cancer biomarker for kidney cancer. Based on patient survival data, high levels of cubilin in tumor cells is a favourable prognostic biomarker in renal cell carcinoma.

In addition to bursting with flavor and texture, asparagus is packed full of nutrients and stripped clean of calories. Four asparagus shoots are only 13 calories with 12% of the Daily Value of vitamin A, 38% vitamin K and 22% folate. This wealth in folate is important because many scientists believe folate deficiency to be one of the most common deficiencies in the USA [1]. Folate deficiency increase ones risk for heart disease and causes megaloblastic anemia which could result in depression, irritability, forgetfulness and disturbed sleep [1]. Additionally, the fetuses of pregnant women who do not consume enough folate are at risk for neural tube defects [1]. Getting enough folate before pregnancy can prevent such mishaps. Fotunately, asparagus is high in folate and other vitamins while it is low in calories and easy to prepare. ...
There has been concern about the interaction between vitamin B12 and folic acid. The National Institutes of Health has found that Large amounts of folic acid can mask the damaging effects of vitamin B12 deficiency by correcting the megaloblastic anemia caused by vitamin B12 deficiency without correcting the neurological damage that also occurs, there are also indications that high serum folate levels not only might mask vitamin B12 deficiency but could also exacerbate the anemia and worsen the cognitive symptoms associated with vitamin B12 deficiency ...
Folate (folic acid) is needed for red blood cells to form and grow. You can get folate by eating green leafy vegetables and liver. However, your body does not store folate in large amounts. So, you need to eat plenty of folate-rich foods to maintain normal levels of this vitamin.. In folate-deficiency anemia, the red blood cells are abnormally large. Such cells are called megalocytes. They are also called megaloblasts. They are seen in the bone marrow. That is why this anemia is also called megaloblastic anemia ...
Vitamin B12 (cobalamin, Cbl) is required for cellular metabolism. It is an essential coenzyme in mammals for two reactions: the conversion of homocysteine to methionine by the enzyme methionine synthase and the conversion of methylmalonyl-CoA to succinyl-CoA by the enzyme methylmalonyl-CoA mutase. Symptoms of Cbl deficiency are hematological, neurological and cognitive, including megaloblastic anaemia, tingling and numbness of the extremities, gait abnormalities, visual disturbances, memory loss and dementia. During pregnancy Cbl is essential, presumably because of its role in DNA synthesis and methionine synthesis; however, there are conflicting studies regarding an association between early pregnancy loss and Cbl deficiency. We here review the literature about the requirement for Cbl during pregnancy, and summarized what is known of the expression pattern and function of genes required for Cbl metabolism in embryonic mouse models.
Mechanism of Drug Drug Interaction : Folate deficiency states may be produced by drugs such as antiepileptics, oral contraceptives, antituberculous drugs, alcohol, glucarpidase, and folic acid antagonists such as methotrexate, pyrimethamine, triamterene, trimethoprim, and sulfonamides. In some instances, such as during methotrexate or antiepileptic therapy, replacement therapy with folinic acid or folic acid may become necessary in order to prevent megaloblastic anaemia developing; folate supplementation has reportedly decreased serum-phenytoin concentrations in a few cases and there is a possibility that such an effect could also occur with barbiturate antiepileptics ...

In this homemade formula, much of the sugar, protein, and fat and half of the calories comes from goat milk.. The majority of the sugar comes from the maple syrup though, which is just sucrose. Just like the sucrose from cane sugar that folks complain about in some organic formulas.. Extra fat comes from the olive oil.. What about the other ingredients?. They provide extra vitamins and minerals, including vitamin D, vitamin A, and iron.. Whats missing?. This homemade formula seems to be missing folate. Goat milk is deficient in folate and can lead to megaloblastic anemia and it is one of the main reasons babies should avoid unfortified goat milk.. And it is missing enough vitamin D to avoid vitamin D deficiency.. Cavallaris recipe seems to add just 100IU of vitamin D to the whole 32 ounce batch (from the cod liver oil). Thats just 10IU per 100ml, about 6 times less than baby formula. Keep in mind that it is recommended that infants get at least 400IU of vitamin D each day.. Remember that ...

Pernicious anemia earned its name because it was once a fatal illness before treatment options were discovered. Now, it is common knowledge in the medical community that pernicious anemia--also known as megaloblastic anemia--can be treated with vitamin B12. As such, vitamin B12 and pernicious anemia are intrinsically linked. What is Pernicious Anemia? Anemia is a medical condition in which the body decreases its production of red blood cells, the bloods hemoglobin count decreases, and/or the blood ...

A deficiency of folate can occur when the bodys need for folate is increased, when dietary intake or absorption of folate is inadequate, or when the body excretes (or loses) more folate than usual. Medications that interfere with the bodys ability to use folate may also increase the need for this vitamin.[5][6][7][8][9][10] Some research indicates that exposure to ultraviolet light, including the use of tanning beds, can lead to a folate deficiency.[11][12] The deficiency is more common in pregnant women, infants, children, and adolescents. It may also be due to poor diet or a consequence of alcoholism.[13] Additionally, a defect in homocysteine methyltransferase or a deficiency of B-12 may lead to a so-called "methyl-trap" of tetrahydrofolate (THF), in which THF is converted to a reservoir of methyl-THF which thereafter has no way of being metabolized, and serves as a sink of THF that causes a subsequent deficiency in folate.[14] Thus, a deficiency in B-12 can generate a large pool of ...
Cubilin is a 460-kd multiligand hydrophobic protein that binds to intrinsic factor cobalamin (Cbl-IF) with a high affinity and that is expressed in both kidney and ileal epithelial cells. Based on this observation, it has been speculated that cubilin and intrinsic factor cobalamin receptor (IFCR) are identical.1Recently, Kristiansen et al showed that the P1297L mutation of cubilin (FM1) associated with selective congenital cobalamin malabsorption (Imerslund-Gräsbeck disease, described in Finnish patients; also named megaloblastic anemia 1 [MGA1]) causes a 5-fold decrease of the binding domain affinity for Cbl-IF.2 They concluded that this decreased affinity explained the malabsorption of Cbl and the Cbl deficiency related to the FM1 mutation of MGA1 patients. In our opinion, the pathogenetic mechanism suggested by Kristiansen et al does not explain the whole biologic phenotype of the Finnish patients. The P1297L mutation of cubilin has been found in 16 of 17 Finnish patients but not in ...
A vitamin B12 test measures the amount of vitamin B12 in the blood. The body needs this B vitamin to make blood cells and to maintain a healthy nervous system.. Vitamin B12 is found in animal products such as meat, shellfish, milk, cheese, and eggs. Most people who eat animal products are not likely to develop vitamin B12 deficiency anemia unless their bodies cant absorb it from food. Strict vegetarians (vegans) who do not eat animal products and babies of mothers who are strict vegetarians are at increased risk for developing anemia and should take a supplement containing vitamin B12. Vitamin B12 is stored in the liver for a year or more, which reduces a persons risk of anemia. Vitamin B12 is usually measured at the same time as a folic acid test, because a lack of either one or both can lead to a form of anemia called megaloblastic anemia. Lack of vitamin B12 also affects the nervous system. ...
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.
The usual signals of iron deficiency are a decreased MCV (or anemia with a low-normal MCV) or elevated RDW. Hypochromia with or without microcytosis on peripheral blood smear is also suspicious. Conditions frequently associated with chronic iron deficiency (e.g., malabsorption, megaloblastic anemia, pregnancy, infants on prolonged milk feeding) should also prompt further investigation. The major conditions to be considered are chronic iron deficiency, thalassemia minor, and anemia of chronic disease. The most frequently used differential tests are the serum iron plus TIBC (considered as one test) and the serum ferritin. Although the serum ferritin test alone may be diagnostic, the test combination is frequently ordered together to save time (since the results of the serum ferritin test may not be conclusive), to help interpret the values obtained, and to provide additional information. Low serum iron levels plus low TIBC suggests chronic disease effect (Table 3-2 and Table 37-2). Low serum iron ...
Macrocytic anemia with abnormal erythropoiesis is a common feature of megaloblastic anemias, congenital dyserythropoietic anemias, and myelodysplastic syndromes. Here, we characterized a family with multiple female individuals who have macrocytic anemia. The proband was noted to have dyserythropoiesis and iron overload. After an extensive diagnostic evaluation that did not provide insight into the cause of the disease, whole-exome sequencing of multiple family members revealed the presence of a mutation in the X chromosomal gene ...
Vitamins DO NOT make a person more energetic. The claims that manufacturers put on the vitamin labels are NOT regulated by the FDA so they can essentially say what they want. Only the Federal Trade Commission can stop a manufacturer from making false claims, but they rarely do it. The only disease a vitamin will cure is one that is caused by a deficiency of the vitamin. For example, if a person has scurvy (Vitamin C deficiency) then the scurvy will be cured by taking Vitamin C supplements. If a person has Megaloblastic Anemia (Vitamin B12 deficiency) then taking Vitamin B12 supplements will cure it. They only way to increase a persons energy level is to (1) get proper sleep, (2) eat properly, (3) have your MD check thyroid function tests and probably a Complete Blood Count to check for anemia. Any slight variation in the Thyroid panels can produce fatigue. That may be why you are so tired. Roxanne M.

Inhibition of thiamine transporters has been proposed as a putative mechanism for the observation of Wernickes encephalopathy and subsequent termination of clinical development of fedratinib, a Janus kinase inhibitor (JAKi). This study aimed to determine the potential for other JAKi to inhibit thiamine transport using human epithelial colorectal adenocarcinoma (Caco-2) and thiamine transporter (THTR) overexpressing cells and to better elucidate the structural basis for interacting with THTR. Only JAKi containing a 2,4-diaminopyrimidine were observed to inhibit thiamine transporters. Fedratinib inhibited thiamine uptake into Caco-2 cells (IC50 = 0.940 µM) and THTR-2 (IC50 = 1.36 µM) and, to a lesser extent, THTR-1 (IC50 = 7.10 µM) overexpressing cells. Two other JAKi containing this moiety, AZD1480 and cerdulatinib, were weaker inhibitors of the thiamine transporters. Other JAKi-including monoaminopyrimidines, such as momelotinib, and nonaminopyrimidines, such as filgotinib-did not have any ...
The risk for developing the alcohol dependence syndrome (ADS) has a substantial genetic component. The human thiamine transporter protein 2 (hTHTR2) is encoded by the SLC19A3 gene, which is on chromosome 2q37. hTHTR2 is responsible for the cellular uptake of thiamine (B1), a water-soluble essential vitamin that plays a fundamental and ubiquitous role in carbohydrate metabolism. This gene was also found to be associated with biotin-responsive basal ganglia disease, an autosomal recessive metabolic disorder characterized by encephalopathy and ophthalmoplegia (Ozand et al., 1998; Zeng et al., 2005). Homozygous or compound heterozygous mutations in SLC19A3 cause two distinct clinical phenotypes: biotin-responsive basal ganglia disease and Wernickes-like encephalopathy. Biotin and/or thiamine are effective therapies for both diseases (Yamada et al., 2010). A missense mutation in exon 5 of the SLC19A3 was found in 18 cases of biotin/thiamine-responsive basal ganglion disease presenting with subacute ...

This type of anemia is usually discovered during a medical examination through a routine blood test. In addition to a complete medical history and physical examination, diagnostic procedures for megaloblastic anemia may include additional blood tests and other evaluation procedures, including the Schilling test.. The Schilling test is performed to detect vitamin B12 absorption. In the Schilling test, vitamin B12 levels are measured in the urine after the ingestion of radioactive vitamin B12. With normal absorption, the ileum (portion of the small intestine) absorbs more vitamin B12 than the body needs and excretes the excess into the urine. With impaired absorption, however, little or no vitamin B12 is excreted into the urine. When impaired absorption is the result, a second Schilling test can be performed with ingestion of intrinsic factor with the radioactive B12 to determine if the problem is due to intrinsic factor production or absorption at the ileum.. ...

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 results of deoxyuridine suppression tests on the bone marrow cells of 14 patients on anticonvulsant drugs, 11 of whom had evidence of megaloblastic erythropoiesis, indicated that the megaloblastic changes and macrocytosis encountered in treated epileptics are often not caused either by folate deficiency or by drug-induced impairment of the 5, 10-methylenetetrahydrofolate-dependent methylation of deoxyuridylate to thymidylate. A folate-related abnormality in the methylation of deoxyuridylate was found in only two of the 11 patients with megaloblastic erythropoiesis. ...

A 59 year old white woman was seen urgently for assessment of a macrocytic anaemia. She had normal serum B-12 concentrations, confirmed on three occasions. 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.. ...
Scientists recommend testing for Pearson syndrome in patients with congenital anemia. Some babies diagnosed with and treated for a bone marrow failure disorder, called Diamond Blackfan Anemia, may actually be affected by a very rare anemia syndrome that has a different disease course and treatment, say scientists from Dana-Farber/Boston Childrens Cancer and Blood Disorders Center.. Genetic analysis of DNA from 175 patients believed to have Diamond Blackfan Anemia, identified eight that showed hallmarks of Pearson Marrow Pancreas syndrome, according to research presented at the 55th annual meeting of the American Society of Hematology.. The treatment choices are difficult in both syndromes, but getting the diagnosis correct is crucial, said Suneet Agarwal, MD, PhD, a pediatric hematologist/oncologist at Dana-Farber/Boston Childrens.
