Background. Clinical operational tolerance was defined as stable normal graft function in the total absence immunosuppression (IS). It may be achieved in up to 20% of liver transplant (LT) recipients. In this observational prospective study we report the outcome of long-term sustained IS avoidance after LT.
Methods. Twenty-two LT recipients (mean age: 68±5.8 years, M/F: 17/5) transplanted at our institution were completely withdrawn from IS. At weaning start, the median follow up from LT was 126±43.9 months. Nine recipients (40.9%) were withdrawn from mycophenolate mofetil and 13 (59%) from calcineurin inhibitors. The median time of weaning process was 7±3.4 months. Liver function tests, renal and metabolic parameters were compared before and after weaning. Evolution and/or new onset of comorbidities were also evaluated during the study period.
Results. The median follow-up of IS weaning was 64±43 months. All patients were alive and in good clinical status. None experienced graft rejection. No difference in terms of liver function (p=0.71), renal function (p=0.82) and lipid profile (p=0.29) were observed over the follow up period. None experienced comorbidities.
Conclusion. IS withdrawal once established seems to be durable and safe for the LT recipients.
