Outcomes of prednisone-tapering regimens for cardiac sarcoidosis: A retrospective analysis demonstrating a benefit of infliximab.

BACKGROUND

The optimal treatment strategy for cardiac sarcoidosis has not been standardized. We examined the effectiveness of three prednisone-tapering treatment regimens for cardiac sarcoidosis.

METHODS

We retrospectively reviewed prednisone-tapering treatment regimens for cardiac sarcoidosis that contained prednisone alone (P), prednisone plus methotrexate (P-M), and prednisone plus infliximab containing regimens (P-I). We defined the success of each regimen as the ability to lower the daily prednisone dose to 7.5 mg or less for 6 or more months without developing an adverse cardiac event. We also examined the lowest effective daily prednisone dose achieved without developing an adverse cardiac event.

RESULTS

We identified 61 treatment regimens in 33 cardiac sarcoidosis patients that were analyzed. The success rate of prednisone-tapering regimens was significantly different P: 8/30, 27%; P-M: 3/23, 13%; P-I: 6/8, 75%., p = 0.04. The lowest effective daily prednisone dose for the regimens was also significantly different: P: 14.1 ± 10.1 mg; P-M: 16.9 ± 9.4 mg; infliximab: 7.8 ± 4.9 mg, (p = 0.03); by both measures the success was greatest with the P-I regimen.

CONCLUSIONS

For the treatment of cardiac sarcoidosis, prednisone-tapering regimens containing infliximab are superior to those containing prednisone alone or prednisone plus methotrexate in terms of reaching 7.5 mg/day of prednisone for more than 6 months and achieving the lowest effective prednisone.
