Paediatric sickle cell and thalassaemia

What we do

We provide care and treatment for children with sickle cell disease and thalassaemia. We have the longest-established clinic in the UK which is run by paediatric (children), haematology (blood), nursing and clinical psychology specialists.

We see children mainly from London and the South East but other parts of the UK as well. Most children are diagnosed when they are born and will receive follow-up in our clinic until they are 18.

As well as our weekly outpatient clinic, we run regular joint sickle cell neurology clinics for children who have had serious problems such as stroke. We also have a day unit for children who need regular blood transfusions.

Our service works closely with the paediatric surgeons and colleagues in the intensive care wards. We monitor children regularly using blood and urine tests and transcranial doppler scans, to pick up those who are at risk of stroke.

We can assess children who have learning difficulties and liaise with schools where appropriate. We can also help children with emotional problems or psychological difficulties.
