Preemptive living donor liver transplantation in glycogen storage disease Ia: case report

Even with substantial progress in the management of patients with glycogen storage disease type Ia (GSD-Ia), hepatic and renal complications may still develop during long-term follow-up. Herein, we report a case of preemptive living donor liver transplantation in a patient with GSD-Ia.

The patient was a 5-year-old boy in whom GSD-Ia was diagnosed at age 10 months. Clinical symptoms included frequent hypoglycemic episodes, hyperlipidemia, hyperuricemia, and growth retardation, which were poorly controlled using conventional treatments. At age 5 years, frequent massive nasal bleeds developed, which led to severe anemia. The patient was brought to our institute for living donor liver transplantation (LDLT). Because GSD-Ia usually responds to dietary and medical treatments, we had a long discussion to determine whether preemptive LDLT was indicated. Transplantation was performed using the left lateral liver segment from the patients mother. The weight of his native liver was almost 2 kg. After reperfusion of the graft, the blood glucose concentration rapidly increased, and regular glucose was administered throughout the operation. The posttransplantation course was uneventful. The patient had no episodes of hypoglycemia with a regular diet. Total cholesterol, triglyceride, and uric acid concentrations also reverted to normal without medication. The patient had a few episodes of nasal bleeding after transplantation, which stopped spontaneously. He was discharged from our hospital with normal liver function.

Patients with GSD-Ia should be considered for preemptive LDLT to improve their quality of life when clinical symptoms do not respond to appropriate treatment.
