58
How many RBC’s are made every second ?
59
Red Cell Production

  • 2,000,000 cells/second
  • 120,000,000 cells/minute
  • 173,000,000,000 cells/day
  • 63,072,000,000,000 cells/year
  • 4,415,040,000,000,000 cells/70 years


60
History of EPO
  • French scientists in Sth America
  • Viault (1890): change in red cell count with altitude
  • Carnot and Deflandre (1906): haemopoietine

Erythropoietin and the treatment of anaemia
73
Known Benefits of Epoetin
  • Correction of anaemia
  • Lowers blood transfusion requirements
  • Improvement in quality of life
  • Reduction in LVH
  • Enhanced cognitive function
  • Makes then feel good: “doctor, can I have my injection more often?”
  • Increased exercise tolerance

The Heart and Chronic Kidney Disease
79
 
80
Haemoglobin and Anaemia
  • Much of the morbidity and mortality among end-stage renal disease patients receiving dialysis is cardiovascular in origin
  • Cardiovascular disease mortality rates in ESRD patients are 20–40 times higher than in the general population
81
CKD - echocardiography
82
How does this happen?
  • It’s like the elastic in your undies ….


  • Stretch them enough and they won’t stay up!

86
LVMi in chronic kidney disease - What is important ?
87
Cumulative Survival vs LVMi
88
Haemoglobin and Anaemia
  • Much of the morbidity and mortality among end-stage renal disease patients receiving dialysis is cardiovascular in origin
  • Cardiovascular disease mortality rates in ESRD patients are 20–40 times higher than in the general population
  • Only 15% have normal left ventricular structure and function at dialysis initiation
  • Observational studies: anaemia appears to play a role in cardiac damage

To tidy up……
  • Role of blood pressure and treatment
  • Benefits of anaemia correction
  • Try to protect the heart from damage
