one marrow to produce red cells. The only advantages of parenteral iron are the following: • Iron stores are rapidly and completely replenished. • There is no doubt about compliance. • It is effective in patients with malabsorption. Parenteral iron should therefore only be considered in the following situations: • malabsorption; • genuine intolerance of oral iron preparations; • when continued blood loss is not preventable and large doses of iron cannot be readily given by mouth; • failure of patient compliance; • when great demands are to be made on a patient’s iron stores (e.g. in an anaemic pregnant woman just before term). IRON DEXTRAN AND IRON SUCROSE INJECTIONS Use These can be administered by deep intramuscular injection (to minimize staining of the skin) or intravenously (anaphylactoid reactions can occur (up 3% of patients) and a small test dose should be given initially). Oral iron should be stopped 24 hours before starting parenteral iron therapy and not restarted until five days after the last injection. Key points Iron replacement therapy • In health, normal iron losses require the absorption of 0.5–1 mg (in males) and 0.7–2 mg (in menstruating females) of iron. • Ferrous iron is best absorbed from the small intestine. • Iron deficiency is the most common cause of anaemia (e.g. malabsorption, menstrual, occult or gastrointestinal blood loss – always determine the cause). • For iron deficiency, 100–200 mg of elemental iron are given orally per day and continued until iron stores are replete, usually within three to six months. • Parenteral iron use is restricted to cases of noncompliance or non-tolerance of oral preparations, or malabsorption states. • During erythropoietin therapy, supplemental iron is given to support increased haem synthesis. VITAMIN B 12 Vitamin B 12 is an organic molecule with an attached cobalt atom. Linked to the cobalt atom may be a cyanide (cyanocobalamin), hydroxyl (hydroxocobalamin) or methyl (methylcobalamin) group. These forms are interconvertible. Sources of vitamin B 12 include liver, kidney heart, fish and eggs. Use Replacement therapy is required in vitamin B12 deficiency which may be due to: • malabsorption secondary to gastric pathology (Addisonian pernicious anaemia, where parietal cells are destroyed by an HAEMATINICS – IRON, VITAMIN B 12 AND FOLATE 391 autoimmune reaction, so intrinsic factor is not produced, resulting in vitamin B 12 deficiency; gastrectomy); • intestinal malabsorption (e.g. Crohn’s disease or surgical resection of the terminal ileum); • competition for vitamin B 12 absorption by gut organisms (e.g. blind loop syndrome due to a jejunal diverticulum or other cause of bacterial overgrowth, infestation with the fish tapeworm Diphyllobothrium latum); • nutritional deficiency – this is rare and is limited to strict vegans. The few such individuals who do develop megaloblastic anaemia often have some co-existing deficiency of intrinsic factor. Vitamin B 12 replacement therapy is given by intramuscular injection. Hydroxocobalamin is preferred, given as an initial loading dose followed by three monthly maintenance treatment for life. Cellular mechanism of action Vitamin B12 is needed for normal erythropoiesis and for neuronal integrity. It is a cofactor needed for the isomerization of methylmalonyl coenzyme A to succinyl coenzyme A, and for the conversion of homocysteine into methionine (which also utilizes 5-methyltetrahydrofolate, see Figure 49.2). Vitamin B12 is also involved in the control of folate metabolism, and B12 and folate are required for intracellular nucleoside synthesis. Deficiency of vitamin B12 ‘traps’ folate as methylene tetrahydrofolate, yielding a macrocytic anaemia with megaloblastic erythropoiesis in the bone marrow, and possible neurological dysfunction, i.e. peripheral neuropathy, subacute combined degeneration of the spinal cord, dementia and optic neuritis. Pharmacokinetics Humans depend on exogenous vitamin B12. Following total gastrectomy liver stores (1–10 mg) are adequate for 3–5 years, following which there is an increasing incidence of vitamin B12 deficiency. The daily vitamin B12 loss is 0.5–3 μg, which results mainly from metabolic breakdown, and 2–3 μg is absorbed daily from the diet. Vitamin B12 is complexed with intrinsic factor (secreted from the gastric parietal cells). Intrinsic factor is a Methylene- THF 2 THF Methyl- THF 1. COMT and other methyltransferases 2.

392 ANAEMIA AND OTHER HAEMATOLOGICAL DISORDERS glycoprotein of molecular weight approximately 55 kDa which forms a stable complex with vitamin B 12. The complex passes down the small intestine and binds to specific receptors on the mucosa of the terminal ileum (at neutral pH and in the presence of calcium) and is actively absorbed. Once in the circulation, vitamin B 12 is transported by the beta globulin transcobalamin II (TC II) to tissues, with its primary storage site being the liver (90% body stores). Vitamin B 12 complexed with other transcobalamins (TCI and III, which are alpha-globulins) probably represent the major intracellular storage form. The normal range of plasma vitamin B 12 concentration is 170–900 ng/L (150–660 pmol/L). Vitamin B 12 is secreted into the bile, but enterohepatic circulation results in most of this being reabsorbed via the intrinsic factor mechanism. FOLIC ACID Uses Folic acid is given to correct or prevent deficiency states and prophylactically during pregnancy. It consists of a pteridine ring linked to glutamic acid via p-aminobenzoic acid (PABA). The richest dietary sources are liver, yeast and green vegetables. Folate deficiency may be due to: • poor nutrition – in children, the elderly or those with alcoholism; • malabsorption – caused by coeliac disease, sprue or diseases of the small intestine; • excessive utilization – in pregnancy, chronic haemolytic anaemias (e.g. sickle cell disease) and leukaemias; • anti-epileptic drugs (e.g. phenytoin). The normal requirement for folic acid is about 200 μg daily. In established folate deficiency, large doses (5–15 mg orally per day) are given. If the patient is unable to take folate by mouth, it may be given intravenously. Patients with severe malabsorption may be deficient in both folic acid and vitamin B 12, and administration of folic acid alone may precipitate acute vitamin B 12 deficiency. Such patients require replacement of both vitamins concurrently. Many patients on chronic anticonvulsant therapy develop macrocytosis without frank folate deficiency. Treatment is by the addition of folic acid to the anticonvulsant regimen. Cellular mechanism of action Folic acid is required for normal erythropoiesis. Deficiency of folic acid results in a megaloblastic anaemia and abnormalities in other cell types. Folate acts as a methyl donor in biochemical reactions, including the methylation of deoxyuridylic acid to form thymidylic acid, as well as other reactions in purine and pyrimidine synthesis. Pharmacokinetics Folate is present in food as reduced polyglutamates. These are hydrolysed to monoglutamate, reduced and methylated to methyltetrahydrofolate by the combined action of pteroylglutamyl carboxypeptidase and tetrahydrofolate reductase. This occurs in the proximal small intestine, the site of folate absorption into the portal blood. About one-third of total body folate (70 mg) is stored in the liver, representing only about four months supply. The normal range for serum folate concentration is 4–20 μg/L. IRON AND FOLIC ACID THERAPY IN PREGNANCY Pregnancy imposes a substantial increase in demand on maternal stores of iron and folic acid. A pregnant woman during the last trimester therefore requires approximately 5 mg of iron daily. Most women are iron depleted by the end of the pregnancy if they do not receive supplements. Requirements for folic acid also increase by two- to three-fold during pregnancy. Folate deficiency is associated with prematurity, low birth weight for gestational age and neural-tube defects (Chapter 9). In the UK, the usual practice is to give iron and folic acid supplements throughout pregnancy. Folate supplementation should be also be given before conception to women who are attempting to become pregnant, in order to reduce the incidence of neural-tube defects. High-dose prophylaxis (folate, 5 mg daily) is advised for women who have previously given birth to a child with a neural-tube defect. Key points Vitamin B12 and folate therapy • Healthy subjects require 3–5 μg of vitamin B12 and 200 μg of folate daily. • Body stores of vitamin B12 are 3 mg; folate stores are approximately 200 mg. • Vitamin B12 and folate are absorbed from the small intestine, and vitamin B12 is specifically absorbed from the terminal ileum. • The most common cause of B12 or folate deficiency is dietary or malabsorption, or due to gastric surgery. • Vitamin B12 deficiency must not be inappropriately treated with folate alone, as any associated neurological damage may be irreversible. • Drugs may cause vitamin B12 (e.g. metformin) or folate (e.g. phenytoin, other anti-epileptic drugs) deficiency. PYRIDOXINE, RIBOFLAVIN Sideroblastic anaemia with failure of incorporation of iron into haem in the mitochondria, may respond to long-term pyridoxine supplementation. Infrequently, red cell aplasia is due to riboflavin deficiency and will respond to supplementation with this vitamin (Chapter 35). HAEMATOPOIETIC GROWTH FACTORS Recombinant DNA technology has been used to synthesize several human haematopoietic growth factors (Figure 49.3 shows an outline of haematopoiesis). Haematopoietic growth factors now have a clear role in the treatment of many forms of bone marrow dysfunction.
