Abstract

Objective Our objective was to evaluate the effectiveness of combination therapy consisting of low-dose corticosteroids with weekly methotrexate in patients with cardiac sarcoidosis in whom long-term therapy is required. Combination therapy was selected because long-term standard corticosteroid therapy tends to result in various adverse effects and the steroid-sparing effects of methotrexate have been reported.
Methods This study was a small open-label study comparing long-term functional changes between patients who received combination therapy (5-15 mg/day of prednisolone and 6 mg/week of methotrexate) and patients who received corticosteroids alone. The comparative analysis was based on the following therapeutic indexes: ejection fraction (EF), left ventricular end-diastolic diameter (LVDd) on echocardiography, serum N-terminal fragment pro-brain natriuretic peptide (NT-proBNP) and cardiothoracic ratio (CTR) on plain chest radiographs.
Patients Seventeen patients with cardiac sarcoidosis were examined in the sarcoidosis clinic. Cardiac sarcoidosis was diagnosed based on the Japanese diagnostic guidelines published in 2006.
Results The EF was significantly stabilized in the combination therapy group but not in the corticosteroids alone group at three years after the first treatment. The CTR and NT-proBNP levels were significantly stabilized in the combination therapy group compared with those observed in the corticosteroids alone group at both three and five years after the first treatment. The LVDd values tended to be stable in the combination therapy group compared with those observed in the corticosteroids alone group. The combination therapy was associated with few adverse effects.
Conclusion Weekly methotrexate therapy with daily small doses of corticosteroids stabilized the EF, CTR and NT-proBNP levels in the serum without eliciting adverse effects longitudinally.
