Infliximab, adalimumab and etanercept are monoclonal antibodies which inhibit tumor necrosis factor alpha (TNF[part]-I) and are used in the treatment of inflammatory diseases such as rheumatoid arthritis (RA) and inflammatory bowel disease (IBD). TNF[part]-I are associated with an increased risk of infections and malignancies. There is no data on outcomes in kidney transplant recipients (KTR) who receive TNF[part]-I.
Here we used the Wisconsin Allograft Recipient Database (WisARD) to describe 15 KTR who received TNF[part]-I between 1997 and 2013. Six patients who received TNF[part]-I pre-transplant were excluded from analysis, as they did not continue therapy post-transplant. Five of the 9 remaining patients were diagnosed with inflammatory disease pretransplant, 4 were diagnosed posttransplant. 1 patient was treated with infliximab for IBD during 2 KTs, 1 patient was treated with adalimumab, then etanercept for RA.
All patients were Caucasian. All were on triple immunosuppressive therapy at transplant except patient #7 who was on dual therapy after early steroid withdrawal. Baseline characteristics are in table 1. Two months after starting TNF[part]-I, the previous immunosuppression (IS) was not changed in 7 patients. The antimetabolite was stopped in 2, SRL was added in 1 and prednisone was decreased in 1. Eight patients had at least 1 infection while receiving TNF[part]-I. Patient #4 had significant infectious complications and died of sepsis. The antimetabolite was stopped in patient #8, this patient had no infections. 3 patients had skin cancers, 1 had lung cancer. Patients #1 and 7 had an episode of rejection. Outcomes are in table 2. Infections and malignancies are known complications of both transplant IS and TNF[part]-I. TNF[part]-I can be used in KT, but the rate of infection is high. We suggest that KTR who require treatment with TNF[part]-I have their baseline IS decreased, for example by stopping or reducing the antimetabolite.
