6-methylprednisolone 'mini-pulses': a new modality of glucocorticoid treatment in systemic onset juvenile chronic arthritis.

From 1989 to 1994 we have been following in our Department 22 patients (12 males, 10 females, age range 1-13.5 years) affected by sJCA who underwent glucocorticoid (GC) treatment. These patients were randomised to receive for 6 months two different GC schedules: group A (12) received 6 methylprednisolone (6MP) i.v. for 3 days with 5 mg/kg/d and for an additional 3 days at 2.5 mg/kg/d followed by po prednisone (1 mg/kg/d); group B (10) received po prednisone (1 mg/kg/d). A remarkable decrease of disease activity and fever score and a prompt improvement of joint involvement were observed. A CPR serum concentration decrease associated to a consistent increase of Hb over baseline values were disclosed in group A. GC cumulative daily requirement was significantly lower in group A. Four patients from group B but only one from group A developed a cushingoid appearance: no differences of BMI were found in the two groups. Our study shows that in sJCA patients i.v. GC mini pulses are effective on early clinical and biological parameters of inflammation and requires a lower cumulative daily dosage than conventional oral GC treatment.
