Biochemical and immunological parameters of sarcoid patients in west Greece

Sera from 55 patients with inactive and active sarcoidosis were analyzed for biochemical and immunological serum factors (immunoglobulins, complement and autoantibodies). These parameters of sarcoid Greek patients are presented for the first time in the literature. They are compared with similar findings in the European and World literature. Summarily the IgM rheumatoid factor (RF) and C4 levels were increased in both sarcoidosis groups. These data suggest that the underlying etiological events of sarcoidosis do exist at a subclinical level.
