Background andAims: Vitamin and iron deficiencies are common in patients with inflammatory bowel disease (IBD) as a result of chronic intestinal inflammation, increase in demand, or dietary restrictions. Here, we assessed the frequency of complications in relation to deficiency of iron, folate acid, and vitamin B12 in patients enrolled in the nationwide Swiss Inflammatory Bowel Disease Cohort Study (SIBDCS). Methods: A total of 2666 patients were included in the study, 1558 with Crohn's disease (CD) and 1108 with ulcerative colitis (UC)...

Folate deficiency causes megaloblastic anemia and neural tube defects, and is also associated with some cancers. In vitro, folate deficiency increases mutation frequency and genome instability, as well as exacerbates the mutagenic potential of known environmental mutagens. Conversely, it remains unclear whether or not elevated folic acid (FA) intakes are beneficial or detrimental to the induction of DNA mutations and by proxy human health. We used the MutaMouse transgenic model to examine the in vivo effects of FA deficient, control, and supplemented diets on somatic DNA mutant frequency (MF) and genome instability in hematopoietic cells...

BACKGROUND: Vitamin B12 deficiency is associated with hematological, neurological, and cardiovascular consequences. Epidemiologic data on these related illnesses indicate gender differences. METHODS: A cross-sectional study was designed to examine gender differences in vitamin B12 deficiency among a healthy population. Data from healthy individuals aged 18-65, who were provided with a routine medical evaluation during 2000-2014, were retrieved from the medical charts...

"Anemias beyond iron, vitamin B12, and folate deficiencies" covers a wide array of everything which lies beyond commonly seen anemias caused by deficiencies of three micronutrients. Although anemias due to deficiencies of iron, B12, and folate are common in daily practice and account for at least one-third of anemia etiologies in older adults, it is not uncommon to encounter other nutritional and toxin-induced underproduction anemias. The combination of thorough clinical examination, careful peripheral blood smear review, and judicious selection of supporting laboratory studies is typically sufficient to make an assertive diagnosis of those cases...

Homocysteine (Hcy) is thiol group containing the amino acid, which naturally occurs in all humans. Hcy is degraded in the body through two metabolic pathways, while a minor part is excreted through kidneys. The chemical reactions that are necessary for degradation of Hcy require the presence of the folic acid, vitamins B6 and B12. Consequently, the level of the total Hcy in the serum is influenced by the presence or absence of these vitamins. An elevated level of the Hcy, hyperhomocysteinemia (HHcy) and homocystinuria are connected with occlusive artery disease, especially in the brain, the heart, and the kidney, in addition to venous thrombosis, chronic renal failure, megaloblastic anemia, osteoporosis, depression, Alzheimer's disease, pregnancy problems, and others...

BACKGROUND & AIMS: Vegetarians and vegans are more vulnerable to vitamin B12 deficiency with severe risks of megaloblastic anemia, cognitive decline, neuropathy, and depression. An easy and simple method of supplementation consists of taking one weekly dosage of 2000 μg. However, single large oral doses of vitamin B12 are poorly absorbed. The present research evaluates the ability of two different sublingual dosages of vitamin B12 (350 μg/week vs 2000 μg/week) in improving cyanocobalamin (vitamin B12 ) nutritional status in vegans and vegetarians with a marginal deficiency...

The term folate (vitamin B9) refers to a group of water-soluble compounds that are nutritionally essential for the support of optimal human health and development. Folates participate in numerous one-carbon transfer reactions, including the methylation of important biomolecules (lipids, amino acids, DNA). A deficiency of folate leads to pathological outcomes including anemia and impairments in reproductive health and fetal development. Due to the linkage of impaired folate status with an increased prevalence of neural tube defects (NTDs) in babies, several jurisdictions required the fortification of the food supply with folic acid, a synthetic and stable form of folate...

All patients with significant gastrointestinal disease should be clinically assessed for protein calorie malnutrition by using the Subjective Global Assessment. Blood tests for anemia, electrolytes, calcium, phosphorus, magnesium, ferritin, vitamin B12 , and folate should be considered for assessment of major micronutrients. Where malabsorption or inflammatory bowel disease is diagnosed, bone mineral density using dual beam x-ray absorptiometry, 25-OH vitamin D levels, and measurement of other vitamins and trace elements should be considered...

RATIONALE: Hereditary folate malabsorption (HFM) is characterized by folate deficiency with impaired intestinal folate absorption and impaired folate transport into the central nervous system. Its manifestations mainly include macrocytic anemia, recurrent infections, and neurological deficits. The neurological manifestations include progressive psychomotor retardation, behavioral disorders, and early-onset seizures. PATIENT CONCERNS: From early infancy, a Chinese boy had experienced macrocytic anemia, leukopenia, thrombocytopenia, recurrent pneumonia, diarrhea, and mouth ulcers...

Anemia and chronic heart failure are frequent comorbidities in geriatric patients. In approximately one third of older adults the cause of the anemia is an iron, vitamin B12 and/or folate deficiency and in another third a chronic inflammatory process is present. In the case of iron deficiency a differentiation must be made between the absolute and functional forms. Although in functional iron deficiency ferritin, as a parameter of iron metabolism, is within the normal range or can even be higher, an iron-deficient erythropoiesis is present...

Folate deficiency can cause a number of diseases including neural tube defects and megaloblastic anemia, and still occurs in both developed and developing countries. Cereal-based food products are staple foods in many countries, and may therefore be useful sources of folate. The production of folate by microorganisms has been demonstrated in some cereal-based fermented foods, but has never been studied in a traditional African cereal based food spontaneously fermented. The microbiota of ben-saalga, a pearl-millet based fermented porridge frequently consumed in Burkina Faso, has a good genetic potential for the synthesis of folate, but the folate content of ben-saalga is rather low, suggesting that folate is lost during the different processing steps...

Folate (vitamin B9) is an essential nutrient required for cell survival, proliferation, differentiation and therefore embryogenesis. Folate deficiency has been associated with many diseases, including congenital heart diseases and megaloblastic anemia, yet the mechanisms underlying these remains elusive. Here, we examine the impact of folate deficiency on the development of the circulation system using a zebrafish transgenic line which displays inducible folate deficiency. Impaired hematopoiesis includes decreased hemoglobin levels, decreased erythrocyte number, increased erythrocyte size and aberrant c-myb expression pattern were observed in folate deficient embryos...

BACKGROUND: Widely spread throughout the world, folate and iron deficiencies are risk factors for many diseases. However, contrary to iron deficiency and anemia, which have been documented in depth, the prevalence of folate deficiency among women has not been well-studied. OBJECTIVE: The aim of this study is to determine the prevalence of folate deficiency and anemia and their association among Senegalese women of reproductive age. METHODS: A national cross-sectional survey using a stratified 2-stage cluster sampling was conducted...

BACKGROUND: Blood test results required for the evaluation of anemia are considered difficult to interpret after red blood cell transfusion. However, this hypothesis is neither supported by a strong physiological rationale nor is it evidence based. METHODS: We conducted a prospective multicenter study to compare the values of key assays prior to and after a course of red blood cell transfusion in the emergency or internal medicine units in 4 university hospitals...

Clinical copper deficiency is now more frequently recognized. Hematologically, it can present as anemia (microcytic, normocytic, or macrocytic) and neutropenia. Thrombocytopenia is relatively rare. Neurologically, it can manifest as myelopathy and peripheral neuropathy simulating subacute combined degeneration. Bone marrow findings can mimic myelodysplasia resulting in occasional inappropriate referral for bone marrow transplantation. Other conditions with similar presentations include infections, drug toxicity, autoimmunity, B12 deficiency, folate deficiency, myelodysplastic syndrome, aplastic anemia, and lymphoma with bone marrow involvement...

BACKGROUND: Hyperhomocysteinemia has been suspected of favoring thrombosis. Several case-control studies and even a meta-analysis have confirmed a link between venous thrombosis and hyperhomocysteinemia. Homocysteine is due to genetic and acquired factors (poor diet in folate and vitamin B12, older age, renal impairment, thyroid diseases, and malignancies) induced by the intake and the concentrations of vitamin B9 or B12 in the majority of cases. CASES PRESENTATION: We report the cases of four Moroccan patients who presented with acute vein thrombosis of different sites: a 34-year-old man, a 60-year-old man, a 58-year-old man, and a 47-year-old woman...

BACKGROUND: Anemia following bariatric surgery is a known complication. To prevent nutrient deficiencies, adolescents require multivitamin/mineral supplementation following bariatric surgery. The purpose of this study was to investigate if routine multivitamin/mineral supplementation is sufficient to prevent anemia in adolescents undergoing bariatric surgery, particularly sleeve gastrectomy (SG), a procedure that may induce nutrient malabsorption. METHODS: We conducted a retrospective review of pediatric patients who underwent SG (34 patients) and laparoscopic adjustable gastric banding (LAGB) (141 patients) (January 2006 through December 2013)...

Black cohosh rhizome, available as a dietary supplement, is most commonly marketed as a remedy for dysmenorrhea and menopausal symptoms. A previous subchronic toxicity study of black cohosh dried ethanolic extract (BCE) in female mice revealed a dose-dependent ineffective erythropoiesis with a macrocytosis consistent with the condition known as megaloblastic anemia. The purpose of this study was to investigate potential mechanisms by which BCE induces these particular hematological changes. B6C3F1/N female mice (32/group) were exposed by gavage to vehicle or 1,000 mg/kg BCE for 92 days...
