Abstract

Neurological complications (NCs) can frequently and significantly affect morbidity and mortality of liver transplant (LT) recipients. We analysed incidence, risk factors, outcome and impact of the immunosuppressive therapy on NC development after LT. We analysed 478 LT in 440 patients, and 93 (19.5%) were followed by NCs. The average LOS was longer in patients experiencing NCs. The 1-, 3- and 5-year graft survival and patient survival were similar in patients with or without a NC. Multivariate analysis showed the following as independent risk factors for NC: a MELD score ≥20 (OR = 1.934, CI = 1.186-3.153) and an immunosuppressive regimen based on calcineurin inhibitors (CNIs) (OR = 1.669, CI = 1.009-2.760). Among patients receiving an everolimus-based immunosuppression, the 7.1% developed NCs, vs. the 16.9% in those receiving a CNI (P = 0.039). There was a 1-, 3- and 5-year NC-free survival of 81.7%, 81.1% and 77.7% in patients receiving a CNI-based regimen and 95.1%, 93.6% and 92.7% in those not receiving a CNI-based regimen (P < 0.001). In patients undergoing a LT and presenting with nonmodifiable risk factors for developing NCs, an immunosuppressive regimen based on CNIs is likely to result in a higher rate of NCs compared to mTOR inhibitors.
