Anaemia of chronic disease
Summary
Definition
History and exam
Key diagnostic factors
- presence of risk factors
- systemic symptoms of underlying condition
- absent history of bleeding
- physical finding suggesting infection
- physical finding suggesting neoplasm
- physical finding suggesting autoimmune disorder
Other diagnostic factors
- absent history of high alcohol intake
- absent history of exposure to chemicals and radiation
- absent history of drugs known to be associated with risk of anaemia
- absent history of poor nutrition
- decreased exercise tolerance
- shortness of breath with exercise
- fatigue
- pallor
Risk factors
- autoimmune disorders
- malignancy
- acute or chronic infection
- critical illness, major trauma, or major surgery with delayed recovery
- chronic disease
Diagnostic investigations
1st investigations to order
- Hb
- WBC and differential
- platelet count
- mean corpuscular volume (MCV)
- mean corpuscular haemoglobin concentration (MCHC)
- peripheral blood smear
- serum ferritin
- serum iron
- total iron-binding capacity
- transferrin saturation
- absolute reticulocyte count
- serum creatinine
Investigations to consider
- C-reactive protein (CRP)
- erythrocyte sedimentation rate
- serum B12
- serum folate
- thyroid function tests
- LFTs
- indirect and direct bilirubin
- LDH
- erythropoietin
- haemoglobin electrophoresis
- bone marrow biopsy
- soluble transferrin receptor
- ratio of soluble transferrin receptor to log ferritin
Treatment algorithm
mild to moderate anaemia (haemoglobin [Hb] 80 to 110 g/L [8 to 11 g/dL])
severe (Hb <80 g/L [<8 g/dL]) or life-threatening (Hb <65 g/L [<6.5 g/dL]) anaemia
