Lecture overview

Severe anaemia is common and life-threatening cause of admission in children in sub-Saharan Africa(sSA) ~ 10% will die in hospital, and ~ 12% die 6 months post-discharge l. Whilst blood transfusions are an important treatment for severe anaemia,  scientific evidence to guide doctors on how much blood to give children, or which children require it is poor.

The TRACT trial showed that children with complicated severe anaemia (Hb <4g/dl or 4-6g/dl with severity signs) who do not have a fever require a larger volume of blood transfusion (30mls/kg whole blood) than current WHO guidelines recommend- halving mortality. Conversely, children with a high temperature, guideline-recommendations (20mls./kg) are correct.

The TRACT trial also showed that children with uncomplicated severe anaemia (no severity signs, haemoglobin 4-6g/dl) do not require an immediate transfusion, as long as they are closely monitored for signs of complications, or their haemoglobin levels dropping, and receive a transfusion at that point.

Learning Objectives:
By the end of this lecture, the attendee will be able to:

  1. Discuss why transfusion guidelines in Africa differ from high-income countries. 
  2. Explore the safety of whole blood versus packed cells. 
  3. Explore the impact of donor blood age (time from collection to transfusion) on outcomes. 
  4. Understand the burden of Sickle Cell Disease on the blood transfusion services in Africa. 
  5. Discuss the impact of severe anaemia on African children and the ensuing risk of heart failure.

Lecture speaker

Professor Kathryn Maitland

Kathryn Maitland is a Professor of Paediatric Tropical Infectious Diseases at the Faculty of Medicine and Director of the ICCARE Centre at the Global Centre of Health Innovation, Imperial College, London and an Honorary Fellow at MRC Clinical Trials Units, University College, London. 

Over the last 20 years, Prof. Maitland has been based full-time at the East Africa, where she leads a research group that has highlighted the unique importance of emergency-care research as a highly targeted and cost-effective means of tackling childhood mortality in resource-limited sub-Saharan Africa. Her major research portfolio includes severe malaria, bacterial sepsis and severe malnutrition. 

 As a Clinical Investigator, Prof. Maitland’s work has focused upon understanding the pathophysiology and conducting clinical trials of emergency interventions to improve outcome. To enable such translational research to occur, she has built up a network of African sites and collaborations spanning the globe bringing sophisticated technologies to apply them in real life circumstances to study common diseases of Africa.
