Use of enteric-coated mycophenolate sodium in liver transplant patients with intestinal intolerance caused by mycophenolate mofetil

Post-transplant gastrointestinal (GI) side effects can impair a patient's quality of life (QoL). This study investigates the improvement in GI side effects and related QoL changes in recipients of liver transplantation (OLT) after converting patients from mycophenolate mofetil (MMF) to enteric-coated mycophenolate sodium (EC-MPS).

Thirty-four patients who underwent OLT and suffered from GI intolerability were included in this study. Infectious causes of GI intolerability were excluded. QoL assessed by the Gastrointestinal Quality of Life Index was evaluated before conversion and at months 3, 6 and 12 post-conversion. All patients received baseline immunosuppression of one calcineurin inhibitor, MMF, with or without steroids. Patients were converted from MMF to EC-MPS on an equimolar basis. Paired t-test was used to assess differences in mean score changes over time.

Conversion from MMF to EC-MPS for GI intolerability post-OLT shows statistically significant improvement in GI-related QoL at 3, 6, and 12 months when compared to baseline assessments (p < 0.05 for total mean score); nonetheless, one-third of patients discontinued EC-MPS. No rejection episodes, deaths or graft loss were seen during the study period.

OLT recipients who develop GI side effects caused by MMF can be safely converted to EC-MPS with improvement to their QoL.
