2 Outline Iron metabolism Treatment options
Clinical use of intravenous iron-current and developing areas

3 Total body iron: 2.5-4 grams
Mostly within the cardiovascular system, liver and muscles1: Red blood cells 1.8 g RES macrophages 0.6 g Liver 1.0 g Bone marrow 0.3 g Muscles (myoglobin) Other tissues 0.1 g Bound to transport protein Transferrin 0.003 g Each ml of blood contains approximately 0.5 mg of iron 1. Hentze MW et al. Cell. 2004;117:285-97

4 Iron content of a balanced diet
A balanced diet contains 5-6 mg of iron/1,000 kcal Recommended amount of iron – Adult man: mg / day – Adult woman: mg / day

5 Iron in diet Richest sources of heme iron -lean meat , seafood. Dietary sources of nonheme iron - nuts, beans, vegetables, and fortified grain products. Heme iron has higher bioavailability than nonheme iron-bioavailability % from mixed diets that include substantial amounts of meat/fish and 5% to 12% from vegetarian diets Vitamin C enhances the bioavailability of nonheme iron Meat, poultry, and fish enhance nonheme iron absorption, whereas phytate (present in grains and beans) and certain polyphenols in some non-animal foods (such as cereals and legumes) inhibit absorption

6 Prevalence of iron deficiency anaemia 1990-19951
Countries Industrialised (%) Developing (%) Children (0-4 years) 20.1 39.0 Children (5-14 years) 5.9 48.1 Pregnant women 22.7 52.0 Women in reproductive age 10.3 42.3 Men (15-59 years) 4.3 30.0 Seniors 12.0 45.2 1. World Health Organisation Iron Deficiency: Assessment, Prevention and Control.

7 Symptoms of iron deficiency with or without anaemia
Shortness of breath Fatigue Reduced physical performance and endurance Decreased concentration span Reduced vitality Increased susceptibility for infections Pale skin colour, hair loss and brittle nails

Iron Therapy With a Special Emphasis on Intravenous Administration (4th edition). UNI-MED Verlag AG, Bremen, Germany, 2008

12 HEPCIDIN and FERROPORTIN
Hepcidin is a hormone produced by the liver Discovered in 2000 Pivotal in iron metabolism, principle regulator Inhibits iron transport across cell membranes via ferroportin In gut prevents iron absorption by blocking iron release from enterocytes In macrophages prevents stored iron release to marrow Hepcidin production inhibited by iron deficiency-increased absorption and release of iron from stores Hepcidin production stimulated by inflammation- poor absorption and iron trapped in stores

14 Absolute & functional iron deficiency
Absolute iron deficiency Depleted body iron stores Low serum ferritin (<100ng/ml) or TSAT <20% Low hepcidin Functional iron deficiency Inadequate iron supply to meet demand despite normal or abundant iron stores Normal or high ferritin levels TSAT <20% High hepcidin ESA, erythropoiesis stimulating agent; TSAT, transferrin saturation Wish JB. Clin J Am Soc Nephrol 2006;1:S4-8

15 Iron replacement strategies
Dietary iron Oral iron Parenteral iron Blood transfusion

16 Oral iron therapy Advantages : cheap : easy to administer
Disadvantages :poorly absorbed(max 5-10 mg/day) :GI side-effects common :compliance often poor :absorption limited if ferritin elevated :absorption reduced in inflammation

17 Limitations of oral iron therapies1,2
Impaired intestinal iron absorption Concomitant food or medication (e.g. phosphate binders, H2 blockers, proton pump inhibitors) – by raising the pH non-haem foods cannot be absorbed Exacerbated by elevated hepcidin and other inflammatory cytokine levels in conditions where there is an inflammatory component May be inadequate during ESA therapy Accelerated erythropoiesis can increase demand for iron beyond the amount supplied orally Gastrointestinal adverse events Can affect over 50% of patients Can adversely affect nutritional intake Improved if iron tablets are taken with food, but this decreases absorption Compliance Pill burden: usually 2 or 3 tablets per day Affected by gastrointestinal intolerance Oxidative stress High oral iron doses can saturate the iron transport system if the iron is rapidly released, resulting in oxidative stress Macdougall IC.

19 Use of intravenous iron
Indicated for treatment of iron deficiency when oral iron preparations are ineffective or cannot be used. Comparative clinical trials show a faster and more prolonged response with IV iron than with oral iron. IV iron is more effective, better tolerated and improves QoL to a greater extent than oral iron. Concerns regarding allergic reactions. 1. British National Formulary (BNF) 2. Gasche C et al.

Oral iron IV iron Blood transfusion Cost1 High iron content Essential in cases of cardiovascular instability1 Non-invasive 100% bioavailable Replaces RBCs Simple administration1 Compliance Convenient 2 Fast acting5 Well tolerated2 Malabsorption in inflammatory conditions3 Potential adverse reactions Potential transfusion reactions6,7 Intolerance3 Invasive Potential poor compliance3 Day case / inpatient Slower to increase haemoglobin vs IV iron4 Cost Cost8 Interactions with many common oral drugs4 Limited supply7 Can delay investigative procedures, i.e. colonoscopies Increased risk of morbidity and mortality in patients with cardiac disease7 Can only absorb 10-20mg a day May worsen outcomes in acute bleeds and surgical cases9 Complex administration7 Advantage Disadvantages Short lasting effect - Most relevant studies show that approximately 20% of the RBCs is lost in the first 24 hr after transfusion. Even more remarkable is that the average life span is 94 days after a storage period of days - Survival of the fittest?--survival of stored red blood cells after transfusion. Luten M et al 2004 1.

Intravenous iron improves Hb responses and reduces ESA requirements-overcomes iron“supply” issue Approved by NICE

28 NICE Guidelines for Anaemia Management in CKD
Recommendation: ‘In non-dialysis patient with anaemia of CKD in whom there is evidence of absolute or functional iron deficiency, this should be corrected before deciding whether ESA therapy is necessary.’ NICE 2011 Anaemia management in people with chronic kidney disease (CG114)

29 NICE Guideline 114 Management of anaemia should be considered in people with anaemia of chronic kidney disease (CKD) when the haemoglobin level is less than or equal to 11.0g/dl. Patients receiving ESA maintenance therapy should be given iron supplements to keep ferritin between µg/l & TSAT >20% or %HRC <6%. In practice it is likely this will require intravenous iron.

30 Obstetrics & Gynaecology

31 Risk factors for iron deficiency in pregnant women 1
Ethnicity Educational level/social class Diet Multiparity Obesity Anaemia during pregnancy Total blood loss at delivery > 0.5L Not exclusively breastfeeding © 1. Bodnar LM et al. Am J Epidemiol. 2002;156:903-12

32 Adverse effects of iron deficiency in pregnancy, at delivery and post partum-maternal
Unpleasant symptoms Lethargy, dyspnoea, fatigue, insomnia, light headedness, dizziness and disorientation Increased susceptibility to infection Decrease in thermoregulation Ante partum haemorrhage ++ Post partum haemorrhage ++ Delayed wound healing Reduced quality and quantity of lactation or even halted Excessive fatigue and failure to cope

33 And for the fetus/baby……….
Poor uterine growth Decreased liquor Asymmetrical growth patterns Small for dates Premature delivery Low birth weight Failure to thrive (poor lactation) And if it continues - poor concentration and reduced scholarly achievements (Source SMA)

34 Antenatal iron deficiency anaemia
Very common Estimated requirements of ~800 mgs extra iron over the course of one pregnancy Detection poor Detection late

35 Iron deficiency anaemia becomes more prevalent as pregnancy progresses
Percentage of women Anaemia* Iron deficiency anaemia** * Hb <11 g/dL in trimester 1, Hb <10.5 g/dL in trimester 2, Hb <11 g/dL in trimester 3 ** Anaemia with serum ferritin <12 ng/mL First trimester Second trimester Third trimester Scholl TO. Am J Clin Nutr. 2005;81:1218S-1222S

36 Iron therapy in pregnancy
Oral iron works well if started early but can be poorly tolerated Intravenous irons are contraindicated in the first trimester – use must be confined to 2nd and 3rd trimesters if benefits outweigh the risks.

38 Post partum iron deficiency
Lethargy, dyspnoea, fatigue, insomnia, light headedness, dizziness and disorientation Increased susceptibility to infection Post partum haemorrhage ++ Delayed wound healing Reduced quality and quantity of lactation or even halted Excessive fatigue and failure to cope

39 44 women with haemoglobin (Hb) of <9 g/dl and ferritin of <15 microgram/l at 24–48 hours post delivery. Oral ferrous sulphate 200 mg twice daily for 6 weeks or 200mg iron sucrose x 2 Women treated with intravenous iron had significantly higher Hb levels on days 5 and 14 (P < 0.01) than those treated with oral iron Conclusion: Intravenous iron sucrose increases the Hb level more rapidly than oral ferrous sulphate in women with postpartum IDA Bhandal N, Russell R.

41 The King’s Lynn experience Midwife-led service for prevention/management of anaemia in pregnancy and reduction of transfusion exposure

42 Background We began to promote the use of intravenous iron in place of blood transfusion having noted that some women who received blood in pregnancy or post partum were iron deficient. OTHER DRIVERS FOR CHANGE Anaemia contributes to adverse outcomes for both mother and baby. Transfusion avoidance is a national UK priority

43 Data from King’s Lynn

44 Units used vs number of women transfused

45 How did we achieve this? Regular interdepartmental meetings
Midwife education days Creating “champions” Designing clear algorithms to empower the midwives to appropriately diagnose and manage anaemia in pregnancy to reduce transfusion rates and rationalise use of intravenous iron. Providing easy access to haematology advice Dietary information emphasised to expectant mothers

46 It starts at booking………
A careful history General health Dietary history Family history Bleeding history – Obstetric and otherwise Any previous history of anaemia? Beliefs and wishes and fears concerning blood transfusion Drug history Allergies esp iron

56 Conclusions Collaboration between laboratory and midwifery staff has improved care of pregnant women by early identification and appropriate treatment of anaemia, reducing pregnancy-related transfusion rates. For laboratory staff, the project delivers on the UK national priority of transfusion avoidance, and has promoted dialogue across the clinical –laboratory interface.    For the midwives, the project has empowered them to independently diagnose and manage anaemia in pregnancy For the mothers and babies, reduction in antenatal and postnatal anaemia is known to improve outcomes. PLUS If applied nationally, this approach would save blood AND increase the blood donor pool

57 Gastroenterology

58 British Society of Gastroenterology
Guidelines for the management of iron deficiency anaemia 2011 Definition of anaemia Iron deficiency* Treatment Acknowledge WHO cut-offs: Men Hb <13g/dl Women Hb <12g/dl Suggest cut-off for diagnosis of anaemia should be the lower limit of the normal range as defined by laboratory doing thr test. Low ferritin (cut-off varies between µg/l in absence of inflammation). Low TSAT. Low iron. Raised TIBC. Raised red cell zinc protoporphyrin. Raised serum transferrin receptor. Reticulocyte Hb content or % hypochromic red cells for diagnosis & monitoring of functional ID. All patients should have iron supplementation to correct anaemia & replenish body stores. Trial of oral or parenteral iron can help distinguish true iron deficiency. For those intolerant or not responding to oral iron parenteral iron preparations can be used. Blood transfusions only for patient with symptomatic anaemia despite iron therapy or those at risk of cardiovascular instability. Iron treatment should follow transfusion to replenish stores. * Values unspecified in guidelines

60 Guidelines on the Diagnosis and Management of Iron Deficiency and Anaemia in IBD (Gasche et al, 2007)

61 Treatment of Anaemia in IBD: Iron Supplementation
The preferred route of iron supplementation in IBD is intravenous, even though many patients will respond to oral iron. Intravenous iron is more effective, better tolerated, and improves the quality of life to a greater extent than oral iron supplements (Grade A). Statement 4a

62 Patient blood management

63 Three pillars of Patient Blood Management

64 In patients undergoing total hip or knee arthroplasty and hip fracture surgery, preoperative anaemia was highly prevalent, ranging from 24 +/- 9% to 44 +/- 9%, respectively. Postoperative anaemia was even more prevalent (51% and 87 +/- 10%, respectively). Perioperative anaemia was associated with a blood transfusion rate of 45 +/- 25% and 44 +/- 15%, postoperative infections, poorer physical functioning and recovery, and increased length of hospital stay and mortality. Treatment of preoperative anemia with iron, with or without erythropoietin, and perioperative cell salvage decreased the need for blood transfusion and may contribute to improved patient outcomes. High-impact prospective studies are necessary to confirm these findings and establish firm clinical guidelines. Spahn DR. Anaesthesiology 2010;113:482-95

65 No life-threatening adverse events occurred with iron sucrose.
31 of 75 women with iron deficiency treated with IV iron preoperatively. IV iron sucrose (760± 290 mg) increased preoperative Hb (Δ Hb: 2.2 ± 1.2 g/dL;P<0.001) and reduced postoperative transfusion rates compared with the control group (32% vs 0%, respectively; P <0.001). Fewer women from the IV iron group were anemic on postoperative day 21 (23% vs 68%; P <0.01). No life-threatening adverse events occurred with iron sucrose. Because of the rapid increase in Hb levels, IV iron sucrose administration seems to be an effective approach for treating preoperative anemia and reducing transfusion rates in this female population.

83 Prevalence of anaemia in CHF
1 2 3 4 5 6 7 8 9 10,11 12 13 14 14 15 Clinicians frequently identify anemia in their older patients, but U.S. national data on the prevalence and causes of anemia in this population have not been available. Data are from the non-institutionalized U.S. population assessed in the third National Health and Nutrition Examination Survey ( ). Anemia was defined by World Health Organization criteria; causes of anemia included iron, folate and B12 deficiencies, renal insufficiency, anemia of chronic inflammation (ACI), formerly termed anemia of chronic disease, and unexplained anemia (UA). ACI by definition required normal iron stores with low circulating iron (< 60 μg/dl). After age 50, anemia prevalence rates rose rapidly, to a prevalence above 20% at age 85 and older. Overall, 11.0% of men and 10.2% of women age 65 and older were anemic. Evidence of nutrient deficiency was present in one-third of older persons with anemia, ACI and/or chronic renal disease in one-third, and UA in the remaining one-third. Most anemia was mild; 2.8% of women and 1.6% of men had hemoglobin < 11g/dl. Therefore, anemia is common, albeit not severe, in the older population, and a substantial proportion of anemia is of indeterminate cause. The impact of anemia on quality of life, recovery from illness, and functional abilities needs to be further investigated in older persons. 1. Cleland JG et al. Eur Heart J 2003;24:442−463 2.
