DefinitionFelty's syndrome is a disorder characterized by rheumatoid arthritis , an enlarged spleen, a decreased white blood cell count , and recurrent infection.
Causes, incidence, and risk factorsThe cause of Felty's syndrome is unknown. It is a variant of rheumatoid arthritis and is more common in people who have had rheumatoid arthritis for a long time. People with this syndrome suffer from an increased incidence of infection associated with a low white blood cell count.
Signs and testsA physical examination shows an enlarged spleen, and may also show an enlarged liver or enlarged lymph nodes. Joint findings are typical of rheumatoid arthritis.
A CBC (complete blood count) may show decreased neutrophil count.
TreatmentPeople with this syndrome are usually already under treatment for rheumatoid arthritis.
Splenectomy (removal of the spleen) may improve the white cell count and the susceptibility to infections.
Expectations (prognosis)Progression of rheumatoid arthritis is likely. Some people benefit from splenectomy.
ComplicationsRecurrent infections may develop.
