Background/Aims
Hepatocellular carcinoma (HCC) most often occurs within hepatocellular adenomas (HCAs) in glycogen storage disease Ia (GSD Ia) patients. The objective of this retrospective study is to assess outcomes after liver transplantation (LT) for GSD Ia where the principal indication for transplantation was prevention of HCC.Methods
Petitions to the United Network for Organ Sharing region 11 review board for additional model for end-stage liver disease listing points were made on behalf of GSD Ia patients. Demographics, pre-operative comorbidity, and outcomes for GSD Ia patients who underwent LT were reviewed.
Results
Between 2004 and 2006, five GSD Ia patients underwent LT. Multiple HCAs with focal hemorrhage and/ or necrosis but without histological evidence of malignancy were identified in all explanted specimens. Four of five patients had complications after LT, including cytomegalovirus (CMV) infections and steroid responsive allograft rejection. Hemoglobin levels and serum triglyceride, total cholesterol, blood glucose, and lactic acid concentrations improved in all patients after LT. Corn starch feeding was not required in any patient after LT. Renal function worsened in three patients despite modifications to primary immunosuppressive medications. All patients are alive at last follow-up (range 25–48 months) and all post-transplant complications have resolved.
Conclusions
By removing all possible adenomatous tissue and reversing the underlying hepatic enzymatic deficiency, LT provides definitive prevention against HCC and correction of most metabolic derangements in GSD Ia patients. Renal dysfunction secondary to GSD Ia persists—underscoring the need for further studies to better understand the mechanisms of renal dysfunction in these patients.
