Cyclosporine-A plus steroids versus steroids alone in the 12-month treatment of systemic lupus erythematosus.

The positive results obtained with cyclosporine-A both in an experimental model and in selected patients with advanced systemic lupus erythematosus support the hypothesis that the drug could be used as a steroid sparer in the earliest stages of active disease. To determine the 12-month clinical efficacy (disease control and steroid sparing), safety, and tolerability of low-dose cyclosporine-A plus steroids versus steroids alone, we designed a multicenter, open, prospective, randomized, pilot study, controlled for parallel groups. The patients were then followed up to month 24. A total of 18 consenting patients with recently diagnosed systemic lupus erythematosus of moderate severity indicated for the use of steroids in acute boluses and subsequently per os were enrolled at two university hospital medical centers. The protocol was based on three 1-g boluses of 6-methylprednisolone followed by cyclosporine-A (<5 mg/kg per day) plus prednisone 0.5-1 mg/kg per day per os, reduced by 5 mg/day every 2 weeks following clinical remission, versus the same doses of oral prednisone alone. The efficacy evaluation was based on a four-point scale (from absent/none to severe) for signs and symptoms of systemic lupus erythematosus and immunoserological parameters. The disease activity index and cumulative prednisone dose per patient were analyzed. Any adverse events were reported. All patients showed a reduction in disease activity index within the 1st month. The results were significantly better in the group with cyclosporine-A plus prednisone throughout month 12 (baseline and 12-month disease activity indexes: 21.3+/-8.6 and 5.0+/-2.5 versus 20.4+/-7.1 and 8.8+/-6.0 in the prednisone group, P<0.05). The 12-month cumulative mean dose of prednisone was significantly lower in the group with both cyclosporine-A plus prednisone (179.4+/-40.1 versus 231.8+/-97.1 mg/kg, P<0.005). No unusual adverse events related to the study drugs have been reported. In particular, renal function and blood pressure monitoring revealed no significant changes from mean baseline values in either group. No disease flares were reported in the group treated with cyclosporine-A plus prednisone during the 12- to 24-month period. Thus cyclosporine-A represents a useful corticosteroid sparer in the maintenance of clinical remission in patients with an early-stage, active systemic lupus erythematosus.
