Abstract

As many as 50% of liver transplant patients suffer gastrointestinal (GI) disturbances post-transplant. Conversion from mycophenolate mofetil (MMF) to mycophenolate sodium (EC-MPS) alleviates GI symptom burden in renal transplant recipients. We employed a validated patient and physician-reported assessment to evaluate the impact of conversion to EC-MPS in liver transplant patients. This is a prospective, longitudinal, single-center, open-label pilot study. Thirty-one MMF-treated liver transplant patients with GI symptoms were converted to equimolar EC-MPS. Gastrointestinal Symptom Rating Scale (GSRS), GI Quality of Life, SF-12v2 and physician-reported assessments were used to evaluate GI symptom burden and severity. A significant improvement in overall GSRS score was noted from baseline (2.57; 95% CI 2.12-3.10) to one month (1.90; 1.68-2.12; p = 0.0007) and three months (1.82; 1.60-2.04; p = 0.0002) post-conversion with significant reductions in all subgroups except Reflux. The overall Gastrointestinal Quality of Life Index (GIQLI) score also showed significant increase in health-related quality of life between one month (90.89; 84.04-97.75) and three months (100.04; 94.57-105.51; p = 0.0009), with all subgroups except social functioning (p = 0.0861) and medical treatment (p = 0.3156) demonstrating significant improvements. This pilot study demonstrates improvement in GI symptom burden when converting from equimolar doses of MMF to EC-MPS. This benefit persisted for three months without evidence of rejection.
