Complications

Chronic lymphocytic leukaemia (CLL) can sometimes cause a number of further complications.

Some of the main problems people with the condition may experience are outlined below.

Infections

People with CLL usually have a weakened immune system and are more vulnerable to infectionsbecause they have a lack of healthy, infection-fighting white blood cells.

Treatment with chemotherapy can also further weaken the immune system.

If you have CLL, it's a good idea to:

• report any possible symptoms of an infection to your GP or care team immediately things to look out for include a high temperature (fever), aching muscles, Traveller's diarrhoea or headaches
• ensure your vaccinations are up-to-date speak to your GP or care team for advice about any additional vaccines you might need, as some aren't safe if you have a weak immune system
• avoid close contact with anyone who has an infection even if it's an infection to which you were previously immune, such as chickenpox

You may also be prescribed regular doses of medications such as antibiotics to help reduce the risk of infection.

Richter's syndrome

In up to1 in every 20 people withCLL, the condition will change to become very similar to an aggressive form of non-Hodgkin lymphoma . This is called Richter's transformation or Richter's syndrome.

Symptoms of Richter's syndrome include:

• sudden swelling of your lymph glands
• a high temperature (fever)
• night sweats
• unintentional weight loss
• tummy (abdominal) pain

Richter syndrome is usually treated with a combination of chemotherapy and other powerful medicines.

TheCancer Research UK website has more information on Richter's syndrome .

Autoimmune haemolytic anaemia

Around1 in every 10 people with CLL will develop a condition called autoimmune haemolytic anaemia.

This is where theimmune systemstarts to attack and destroy red blood cells. It can cause severe anaemia, making you feel breathless and easily tired.

It's usually treated with steroid medication .

Psychological effects

Being diagnosed with CLL can be very distressing and difficult to take in at first, particularly as it can't necessarily be cured and you may be advised to wait for it to get worse before starting treatment.

Having to wait years to see how the condition develops can also be very stressful and make you feel anxious or depressed . Speak to your GP or care team if you're finding it difficult to cope.

You may also find it useful to talk to other people who are living with leukaemia. Your GP or care team willbe able to provide you with the details of support groups in your area.
