BACKGROUND AND AIMS.: Liver transplantation (LT) is currently contraindicated in patients with residual or metastatic lesions of alveolar echinococcosis (AE). We evaluated the long- term course of such patients who underwent LT and were subsequently treated with benzimidazoles. METHODS.: Clinical, imaging, serological and therapeutic data were collected from 5 patients with residual/recurrent lesions of AE who survived for more than 15 years; these patients were from a cohort of 23 with AE who underwent LT at 2 LT/AE referral centers and were subsequently followed up prospectively. Since 2004, images of FDG-positron emission tomography (FDG-PET) were available, and levels of serum antibodies against Echinococcus (E.) multilocularis-recombinant antigens were evaluated. RESULTS.: Median survival of the 5 patients after LT was 21 years. Four of 8 patients with residual/recurrent AE versus 4 of 9 patients without residual/recurrent AE were alive in September 2009. High doses of immunosuppressive drugs, late introduction of therapy with benzimidazoles, withdrawal of such therapy because of side-effects or non-adherence to such therapy, adversely affected prognosis. Administration of appropriate doses of benzimidazoles inhibited the growth of residual/recurrent E. multilocularis. Anti-Em2(plus) and anti-rEm18 antibody levels and standard FDG-PET enabled the efficacy of therapy with benzimidazoles to be assessed. However, meaningful variations in levels of antibodies were observed below diagnostic cut-off values, and images of the uptake of FDG 3 hours after its injection were more sensitive than those obtained 1 hour after its injection in monitoring the metabolic activity of parasitic lesions. CONCLUSIONS.: Benzimidazoles can control residual/recurrent lesions of AE after LT. Monitoring levels of anti-rEm18 or anti-Em2(plus) antibodies and delayed acquisition of FDG-PET images can improve the functional assessment of disease activity. Potential recurrence of disease, especially in patients with residual or metastatic lesions of AE, should not be regarded as a contraindication to LT, even when AE is considered to be lethal in the short-term.
