Maintenance Immunosuppressive Treatment of Renal Transplant Recipients in the Critical Care Unit

Abstract

BackgroundIn intensive care unit (ICU), although there is no standard protocol for maintenance of immunosuppressive (IS) treatments for the kidney transplant recipients (KTx), the dose and the number of IS drugs are decreased according to the center’s experience. The aim of this study is to evaluate the changes in IS treatment during stays in the ICU and to evaluate the safety and results of this modification on the IS treatment in the ICU arbitrarily. MethodWe evaluated retrospectively our kidney transplant recipients in ICU between 2012 and 2017. The immunosuppressive protocols and the results were taken from the ICU documents. ResultsA total of 31 (18 male, 13 female) patients were suitable for the analysis. They were all under the triple IS protocol including Tacrolimus (Tac) + Mycophenolate mofetil (MMF) + steroid before the admission. The reason for ICU admission were severe sepsis in all patients. In ICU, 16 patients (51.6%) died, and a total of 10 patients were lost with functional graft. Change in IS treatment is as follows: a total of the 23 patients (74.2%) were given only steroids, and 8 patients (25.8%) were changed from triple to 2 drugs. Acute kidney injury developed in 42% (13 patients) of the patients in ICU. ConclusionIn our study, we observed that life-threatening severe infections were the main cause of ICU admission in KTx. Reduction in IS treatments are common practice, and reduction to a single dose of steroid was the most frequently chosen IS treatment. Eighty percent of patients are discharged with reduction of steroid gradually. None of the patients developed acute rejection and permanent graft injury.
