Infections & staying protected

Infection was historically the second most common cause of serious illness in thalassaemia, so it deserves attention. The risk is a little higher for several reasons: excess iron can feed some bacteria, a removed spleen adds risk, and blood transfusions can (rarely, now) transmit infection.

One specific point: a bacterium called Yersinia enterocolitica thrives on iron and on the chelator deferoxamine. So if you develop fever with tummy pain and diarrhoea, tell your team — deferoxamine is usually paused until infection is excluded and treated.

Protect yourself: keep vaccinations up to date (hepatitis B for everyone, plus the extra pneumococcal, meningococcal, Hib and annual flu vaccines advised around splenectomy), practise good hygiene and dental care, and don’t ignore fevers. If you’re on deferiprone, keep to the blood-count checks that guard against a rare drop in infection-fighting white cells.

Any significant fever — especially if you’ve had your spleen removed — should be treated as urgent.
