Changes of immunological parameters during auranofin treatment in children affected with juvenile chronic arthritis.
Auranofin [S-triethylphosphine gold-2,3,4,6 tetra-O-acetyl-l-thio-beta-D-glucopyranoside) SK&F 39162) has been administered at 0.1-0.25 mg/kg/day as the sole remission-inducing drug to 46 children affected with juvenile chronic arthritis (JCA). There were 22 males and 24 females; 12 children were affected with pauciarticular onset JCA, 26 with polyarticular onset JCA and 8 with systemic onset JCA. Three sets of efficacy criteria were evaluated quarterly: eight clinical, (Ritchie Index, number of affected, swollen and limited joints, number of joint with increased temperature, morning stiffness, Steinbrocker functional class, physician's disease evaluation), three hematochemical and one therapeutical. In most patients a panel of immunological parameters was routinely performed inclusive of peripheral blood lymphocyte subsets, serum immunoglobulins and C3c-C4 complement components. Patients who showed a definite improvement of at least two out of the three orders of efficacy criteria were classified as responders to auranofin. Out of the 35 patients evaluable after at least six months of treatment there were 24 (68%) responders. Nonresponders had a basal higher level of serum IgA and a basal lower level of serum C4. Both responders and nonresponders presented a reduction of the T4/T8 ratio during auranofin treatment, while only in responders did the basal high levels of IgG and C3c show a definite decrease.
