Felty syndrome is a rare disorder that involves rheumatoid arthritis, a swollen spleen, decreased white blood cell count, and repeated infections.
The cause of Felty syndrome is unknown. It is more common in people who have had rheumatoid arthritis for a long time. People with this syndrome are at risk of infection because they have a low white blood cell count.
A physical examination will show:
A complete blood count ( CBC) may show decreased number of white blood cells called neutrophils.
An abdominal ultrasound may confirm a swollen spleen.
Persons with this syndrome are usually already receiving treatment for rheumatoid arthritis. They may need other medicines to suppress their immune system.
Some people benefit from removal of the spleen (splenectomy).
Rheumatoid arthritis is likely to get worse.
You may have infections that keep returning.
Call for an appointment with your health care provider if you develop symptoms of this disorder.
There is no known prevention.
