Liver Transplantation for Incurable Alveolar Echinococcosis: An Analysis of Patients Hospitalized in Department of Tropical and Parasitic Diseases in Gdynia.

Introduction: Alveolar echinococcosis is a parasitic disease caused by the larval stage of tapeworm Echinococcus multilocularis. It usually involves the liver, but can spread to other organs. The treatment of choice is a surgical resection supported by antiparasitic drugs. In the advanced stages of the disease a liver transplantation is the only option.

Aim: This article presents the problems related to care of patients after liver transplantation for advanced alveolar echinococcosis.

Material: Sixty-seven patients with alveolar echinococcosis were hospitalized in our clinic in the years 2000-2015. Liver transplantation has been a therapeutic option for 9 patients. We retrospectively analyzed data of qualification for the liver transplantation and the postoperative treatment.

Results: Follow-up time after liver transplantation ranged from 7 months to 155 months (average, 6.4 years). One patient, with a history of advanced disease (P4N1M0), died due to liver failure. One patient was lost to follow-up. After liver transplantation all patients were receiving albendazole treatment. Two patients did not follow the medical recommendations. In 1 patient, who decided to stop therapy after 1 year, the relapse of alveolar echinococcosis in the left lobe of the transplanted liver passing through the diaphragm to the pericardium was detected. In another case we suspected a relapse of alveolar echinococcosis in transplanted liver due to positive serological tests.

Conclusion: The prognosis of patient after liver transplantation for alveolar echinococcosis is good. The main problem caused by immunosuppressive therapy is a recurrence of disease in the transplanted liver.
