| アブストラクト | OBJECTIVE: The calcineurin inhibitor tacrolimus has been widely used to prevent allograft rejection after transplantation. The purpose of this study was to clarify the adverse events associated with tacrolimus in solid organ transplantation using a spontaneous reporting system database. MATERIALS AND METHODS: We performed a retrospective pharmacovigilance disproportionality analysis using the Japanese Adverse Drug Event Report (JADER) database. Adverse event reports submitted to the Pharmaceuticals and Medical Devices Agency were analyzed, and the reporting odds ratio (ROR) and 95% confidence interval (CI) for each adverse event were calculated. RESULTS: The database comprised 26,620 reports associated with tacrolimus, of which 2,014, 1,988, and 725 reports involved heart, kidney, and liver transplantation, respectively. Infectious disorder was commonly detected in these transplant patients. There was a significant association between tacrolimus use and colon cancer in patients undergoing heart transplantation (ROR: 3.33, 95% CI: 2.18 - 5.08), but not kidney or liver transplantation. Tacrolimus use in those undergoing kidney transplantation is strongly associated with bronchitis (ROR, 8.95; 95% CI, 6.34 - 12.6). A signal for seizure was detected in liver transplant patients with tacrolimus (ROR, 4.12; 95% CI, 1.77 - 9.59). CONCLUSION: It was suggested that there is a diversity in the strength of the association between tacrolimus and adverse events in patients receiving heart, kidney, and liver transplantation. Our results may provide useful information for treatment with tacrolimus, although further research with more data is needed to clarify this. |
