RESUMO
Mucormycosis is a rare but emerging fungal infection complicating solid organ transplantation (SOT), with a cumulative incidence of around 2% during the first year after SOT. The associated mortality rate is high, and surgical debridement is frequently required as part of the treatment along with antifungal therapy based mostly on amphotericin B formulations, We describe here an unusual case of hepatic mucormycosis in a liver transplant recipient that was successfully treated with clinical therapy based on liposomal amphotericin B followed by posaconazole, without surgical resection.

This paper summarizes the 20 years of liver transplantation in Brazil, in the context of the Western world scenario. More than 5000 liver transplantations have been performed in the country since September 1, 1985. The living-donor liver transplantation, one of the landmarks in liver transplantation, was first described by our team in 1989. Brazil is the seventh country in number of liver transplants in the Western world and the first in Latin America. Almost 1000 procedures were performed in 2004, 19% of them involving living donors.

BACKGROUND: Use of polyclonal anti-hepatitis B surface antigen immunoglobulin (HBIg) has been shown to reduce hepatitis B virus (HBV) recurrence after liver transplantation (LT) and to decrease the frequency of acute cellular rejection (ACR). However, the protective role of HBIg against ACR remains controversial, since HBV infection has been also associated with a lower incidence of ACR. AIM: To assess the relationship between HBIg immunoprophylaxis and the incidence of rejection after LT. METHODS: 260 patients (158 males, 43 +/- 14 years old) submitted to LT were retrospectively evaluated and divided into three groups, according to the presence of HBsAg and the use of HBIg. Group I was comprised of HBsAg-positive patients (n = 12) that received HBIg for more than 6 months. Group II was comprised of HBsAg-positive patients that historically have not received HBIg or have been treated irregularly for less than 3 months (n = 10). Group III was composed of 238 HBsAg-negative subjects that have not received HBIg. RESULTS: HBIg-treated patients (group I) had significantly less ACR episodes, when compared to group II and III. No differences between groups II and III were observed. CONCLUSIONS: Long-term HBIg administration contributes independently to reduce the number of ACR episodes after LT.
