LONDON: British-Pakistani paediatric consultant Dr Sher Bahadur Anjum has successfully treated two young thalassaemia patients through gene therapy, transforming their lives to complete normality — for the first time in the UK.
Dr Anjum, who specialises in haematology (blood disorders) at Newham Hospital in East London, part of Barts Health NHS Trust, led a team of carers at the Newham Hospital to treat the two young boys, now aged 11 and 13, of Bangladeshi background.
Thalassemia is a genetic condition that is most common in those who are Pakistani, Indian, and Bangladeshi. It is a blood disorder, and people with thalassemia have low iron and oxygen levels in the body. This can make them severely anaemic — tired, short of breath, and pale.
To treat their thalassemia, the two patients needed to go to the hospital for blood transfusions every month, which had a major impact on their quality of life. The only cure is a stem cell or bone marrow transplant, but this is not done very often because of the risks involved, and it can be difficult to find donors.
Thanks to an innovative new gene therapy administered by Dr Anjum and his team, working with Great Ormond Street Hospital (GOSH), the two young boys, now aged 11 and 13, are now living healthy, happy lives without further hospital visits or regular blood transfusions.
Before getting the 4-week treatment at GOSH, Dr Anjum and the healthcare team at Newham Hospital conducted extensive pre-gene therapy care over three months, which included blood testing, vaccinations and maintaining the correct haemoglobin levels. Their care at Newham also continued long after the treatment, with monitoring, blood counts and managing the side effects.
When Dr Anjum first approached the families, they were both hesitant to start this therapy as it was new, and requires an initial longer hospital stay. However, after almost 12 months of speaking to them, listening and answering their questions and concerns, they were reassured to start the treatment for their children.

This is an inspiring milestone in medical science. Huge respect to Dr. Sher Bahadur Anjum and his team for their dedication and care. Transforming the lives of these young patients through gene therapy is not just a medical achievement, but a life-changing moment for their families. It’s heartening to see such groundbreaking work happening in the UK, especially led by professionals from diverse backgrounds. A true example of compassion, patience, and innovation in healthcare
