Question

18.1 The following data refer to a 65-year-old male admitted to ICU with septic shock on a background of active rheumatoid arthritis.

  • a) What abnormality is demonstrated in this patient? Give your reasoning. (20% marks)
  • b)  What is the pathogenesis of these changes? (20% marks)
  • c)  What specific treatment strategy would correct the demonstrated abnormality? (10% marks)

18.2 The following data refer to a 48-year-old female admitted electively to ICU following extensive pelvic surgery for invasive endometrial carcinoma. The patient has remained in ICU for 22 days because of complications including acute kidney injury.

  • a) What abnormality is demonstrated in this patient? Give your reasoning. (20% marks)
  • b) Give two potential causative factors in this patient. (10% marks)
  • c) Briefly outline the available treatment options to correct the demonstrated abnormality including any disadvantages / risks. (20% marks)

Answer

Answer and interpretation

18.1 a) Anaemia of Inflammation demonstrated by:

  • decreased haemoglobin
  • decreased iron
  • normal to high ferritin
  • suppressed erythropoietin
  • elevated CRP

b) Inflammation -> cytokines (IL6) -> increased hepcidin -> decreased iron release from bone marrow, decreased iron release from macrophages, decreased absorption of iron -> suppressed erythopoeisis

c) Control inflammation, no value to iron replacement, no value to the use of erythropoietin.

18.2 a) Iron deficiency anaemia as evidenced by:

  • decreased haemoglobin
  • decreased iron
  • decreased ferritin
  • increased erythropoietin
  • increased TIBC.

b) Blood loss; Pre-existing dietary deficiency

c)

  • IV iron replacement – no demonstrated benefit and risks of adverse effects (awaiting Ironman study)
  • Oral iron replacement
  • Erythropoeitin – expensive and no demonstrated benefit
  • Blood transfusion – risks of transfusion including immunosuppression
  • Nil – may have reduced oxygen carrying capacity for some time until correction of Hb
