Abstract | BACKGROUND: METHODS: A single-center open study was conducted of 15 patients whose treatment was converted to tacrolimus from cyclosporine. Of the 15, 12 patients had BOS characterized by sustained loses in lung function while receiving cyclosporine. Rate of decline of forced expiratory volume in 1 second (FEV1) for the 12 patients was calculated before and after administration of tacrolimus. Biochemical changes before and after conversion were compared for the entire group. RESULTS: Median monthly rate of decline in FEV1 was significantly reduced after administration of tacrolimus (5.3% vs 1.1%; p = 0.002). Forced vital capacity did not change significantly. No subjects experienced at least a 10% improvement in FEV1. At least a 10% further decline in FEV1 was noted in five subjects, and seven subjects had no change (i.e., within 10% of baseline). A minor nonsignificant increase in creatinine occurred after administration of tacrolimus. Blood cell count, electrolytes, and liver enzymes remained unchanged. The median change in fasting blood glucose was +0.7 mmol/L (p = 0.02). CONCLUSION: Although tacrolimus does not reverse changes in FEV1 with BOS, in this nonrandomized study it seemed to be associated with a decrease in the rate of decline in lung function and no significant sustained toxicity. Further studies are necessary to substantiate this observation.
