Summary

Objective

Anaemia – is an important public health issue

Anaemia: Definition

• Definition:Anaemia is a symptom of disease that requires investigation to determine the underlying etiology.

It is defined as a decrease in red blood cell mass but in practice it is defined by haemoglobin concentrations below:

– males 13.0 g/dL (WHO)– females 12.0 g/dL (WHO)

Anaemia

• Prevalence– Widespread public health problem with major consequences for

human health and socio-economic development– WHO estimates 2 billion people are affected worldwide– >50% due to iron deficiency

• Effects on health– Increased maternal and child mortality– Decreased cognitive and physical development in children– Decreased productivity in adults– Increased risk of postoperative morbidity and mortality

Anaemia

• Causes– Nutritional deficiencies

• Iron, B12, Folate, Vitamin A

– Infectious diseases• Malaria, helminth infections (hookworm and schistosomiasis), HIV

– Thalassaemias, sickle cell, haemolytic anaemia, leukaemia

– Cancer, chronic renal disease, diabetes, heart disease, rheumatoid arthritis, gastrointestinal disease

– Chemotherapy, radiotherapy

Anaemia: Symptoms

Signs depends on the severity of anaemia

Two general reasons for anaemia– decreased red cell production– increased red cell destruction

• Anaemia in childrenAnaemia in children– Range from 4 to 7%

– Impaired cognitive performance, motor development, coordination, language development

• Anaemia in pregnant womenAnaemia in pregnant women– Range from 6 to 30%

– Risk factor for premature delivery, low birth weight, possible inferior neonatal health

Anaemia of Cancer

• Many factors contribute to anaemia in cancer:Many factors contribute to anaemia in cancer:

– BleedingBleeding– HaemolysisHaemolysis– Marrow infiltration by tumor cellsMarrow infiltration by tumor cells– Nutritional deficienciesNutritional deficiencies– Cytokine-mediated anaemiaCytokine-mediated anaemia– ChemotherapyChemotherapy– Radio-induced myelosuppressionRadio-induced myelosuppression

From European Cancer Anaemia Survey, Abstract in Blood 2002

Anaemia of Renal Failure

• Anaemia of chronic renal Anaemia of chronic renal disease is caused by the disease is caused by the inadaequate production of inadaequate production of Eythropoetin hormone due to Eythropoetin hormone due to reduced mass of functioning reduced mass of functioning kidney tissuekidney tissue

• Prevalence of anaemia is Prevalence of anaemia is correlated to the level of correlated to the level of kidney destructionkidney destruction

Anaemia of Renal Disease

• Chronic Renal Insufficiency– Progressive destruction of renal mass– Evaluated and staged with rate of glomerular filtration (not only,

Creatinin clearance: 15-80 mL/min)

• Anaemia in Chronic Renal Insufficiency:– Increased risk of mortality and cardiac complications

• For every 1g decrease in Hb concentration, there is a 6% increase in the risk of left ventricular hypertrophy

– Third National Health and Nutrition Examination Survey in US( Hb < 12 g / dL)

• 1,200,000 women• 300,000 men ( J Am Soc Nephrol, 2002)

Anaemia of Renal Disease

• Chronic renal failure:

– Very low glomerular filtration rate ( <10 -15 mL/min)

– Treatment: kidney transplantation or dialysis

– Anaemia is corrected by substitutive rhEpo but Hb monitoring is required

– In US:• 1,200 people per million population

– In Europe:• 700 people per million population

( Nephrol Dial Transplant, 2002)

Combining Hardware, Reagents and InformationExample: Pernicious Anaemia

• Prevalence– Major cause of vitamin B12 deficiency in developed countries. – Underdiagnosed.

• Chronic and autoimmune illness with malabsorption of B12 due to Intrinsic Factor deficiency

– Destruction of parietal cells from the gastric mucosa leading to failure of IF production.– Occurrence of autoantibodies to gastric parietal cells or to IF.– End-stage of autoimmune destruction of gastric mucosa.

• Clinical signs– Silent until the end-stage.– First: megaloblastic anaemia– Weakness, weight loss, non specific GI symptoms, neurological symptoms ( senile dementia...)– Associated with other autoimmune diseases: hypothyroidism, Graves' disease, thyroiditis, Addison's disease– Associated with a higher risk to develop gastric cancer

Case Study

• A woman consults GP for weakness and palor

• GP suspects anaemia – Prescription for a CBC– Anaemia confirmed with normal/high MCV

• B12 and Folate are tested

• Use of an expert system

Common medical practice according to Philippe Day, UK

• Which tests can be addedSoluble Transferrin receptor in combination of Ferritin and MCH (CHr), LHD% (%Hypo), IRF in three days will suspect that the patient respond or not with the treatment.

• Soluble Transferrin Receptor in combination with Ferritin will reduce the time for diagnosis and address directly the treatment, EPO, etc. and in case of Mixed ACD-ID it will reduce the time for the correction of the anaemia because only with iron the patient will remain anaemic for a minimum of 3 months with all its effects.

• Secondary diagnosisEasy detection of unknown disease (TBC) that will appear after the diagnosis of ACD

EPO Treatment in Anaemia of Cancer

• Anaemia treatment with rHuEPO

• High cost

• 50% response rate

• Need to predict response rate to treatment

• IVD EPO helps to predict response

Common Practice

• Transfusion of erythrocyte units instead of EPO therapy?
