title: Felty's syndrome treated with rhG-CSF associated with flare of arthritis and skin rash.
abstract: A patient with Felty's syndrome and rheumatoid arthritis was treated with recombinant granulocyte stimulating factor rhG-CSF (Neupogen) in view of severe neutropenia. He had a prompt rise in his neutrophil count and associated with this a severe flare of his arthritis and a skin rash. rhG-CSF was stopped, his neutrophil count fell rapidly and his symptoms resolved. rhG-CSF and the resulting rise in neutrophil count may be associated with flare of autoimmune disease in susceptible individuals.
