• Six patients with refractory neurosarcoidosis were enrolled in a 12-month open-label trial to investigate the safety and efficacy of cyclosporine therapy. Patients were stabilized on a corticosteroid dose, randomized to a low-dose or high-dose cyclosporine group (with appropriate target whole blood cyclosporine levels) for 6 months, and assessed by prospectively defined studies. The corticosteroid dose was adjusted as clinically tolerated. We found that the corticosteroid dose could be lowered to 30% to 58% of the initial stabilization dose in conjunction with cyclosporine therapy, at the time of maximal clinical and laboratory improvement. However, four patients deteriorated while using corticosteroids and cyclosporine; one of these patients died. At the time of clinical deterioration, the prednisone dose ranged from 6 to 22.5 mg daily (or the equivalent). No serious toxic effects developed from cyclosporine therapy. Cyclosporine treatment is a reasonably safe and effective adjunct to corticosteroid therapy for patients with refractory neurosarcoidosis, although clinical deterioration can occur despite combination therapy.
