In most countries, the classic treatment for cobalamin deficiency is based on parenteral administration as intramuscular injections in the form of cyanocobalamin and, more rarely, hydroxylor methylcobalamin [1]. In USA and UK, doses ranging from 100 to 1,000 μg per month (or every 2-3 months when hydroxocobalamin is given) are used for the duration of the patient’s life [2]. In France, treatmen...

BACKGROUND Vitamin B12 deficiency is associated with many adverse health outcomes and is highly prevalent worldwide. The present study assesses the prevalence and socio-demographic factors associated with vitamin B12 deficiency in a representative sample of pregnant women in Colombia. METHOD We used data from the cross-sectional, nationally representative survey (ENSIN, 2010). A total of 1.78...

This review apprises the reader of recent advances in cobalamin absorption and transport since 1970. This field has been of interest to gastroenterologists, hematologists, and biochemists as well as nutritionists. Clinical conditions leading to cobalamin deficiency present especially to the first two of these specialties. Many recent advances involve biochemical definition of the specific trans...

We report the case of a 7-month-old breast fed infant who presented with a nose bleed and bruises. Investigation showed severe nutritional B12 deficiency anemia with a pancytopenia. It is important to take the nutritional history of both the infant and the mother for early prevention and treatment.

Anemia is a common complication of human malaria. Since micronutrient deficiencies are highly prevalent in malaria-endemic areas and appear to contribute to anemia etiology, we conducted a cross-sectional study in Tumaco, Colombia, to examine the associations between plasma vitamin B12 or erythrocyte folate concentrations and hemoglobin (Hb) among 96 adults with predominantly Plasmodium falcipa...

We report a case of anaphylactic reaction to intramuscular injection of cyanocobalamin. This 52-year-old lady was diagnosed as a case of megaloblastic anemia secondary to dietary vitamin B12 deficiency. She had severe anaphylactic reaction after the parenteral administration of cyanocobalamine. Later she received oral vitamin B12 with no adverse effects. The purpose of this case report is to dr...

Vitamin B12 deficiency is an uncommon cause of pyrexia. We report the case of a patient who presented with pyrexia and anaemia, which after exclusion of infective, inflammatory or endocrine causes was attributed to megaloblastic anaemia secondary to vitamin B12 deficiency. The patient's fever responded to treatment of vitamin B12 deficiency.

Pancytopenia can rarely complicate Grave's disease. It can be due to uncontrolled thyrotoxicosis or as a result of rare side effect of antithyroid medication. Pernicious anemia leading to Vitamin B12 deficiency is another rare associated cause. We report a case of a patient with Grave's disease and undiagnosed pernicious anemia whom was assumed to have antithyroid drug induced pancytopenia. Fai...
