[Infectious complications in liver transplant in Italy: current status and prospectives]. / Complicanze infettive nel trapianto di fegato in Italia: stato attuale e prospettive di studio.

The impact of infections in orthotopic liver transplantation (OLT) is remarkable. Studies have shown that about 60% of patient may develop at least 1 infectious episode during the first 3 months after transplant. Within the frame of a Finalized Research Project of the Italian Ministry of Health, during the year 2000 a group of investigators belonging to the major Italian Liver Transplant Centers (LTC)--18 out of 20 Centers--met three times in Genoa with the aim of constituting a Research Group aimed at improving our knowledge of infectious complications in liver transplant recipients (PITF = Program of Infections in Liver Transplantation). The group first collected information about anti-infective procedure in LTC. The study shows that no Center is supported by a Intensive Care Unit (ICU) exclusively dedicated to the LTC, although 37% of them have a partially dedicated Unit. Surveillance cultures are routinely performed and are frequently used to address the choice of the antibacterial and antifungal regimes. Selective Bowel Decontamination is also very common. The management of CMV infection is usually performed as indicated in international guidelines.

Antigen detection in the diagnosis and management of a patient with probable cerebral aspergillosis treated with voriconazole.

This report describes the diagnosis and management of a 16-year-old boy who developed neurological signs and symptoms suggestive of cerebral aspergillosis following a haploidentical bone marrow transplant. A new sandwich enzyme-linked immunosorbent assay (ELISA) for the detection of Aspergillus galactomannan circulating antigens (Platelia Aspergillus, Sanofi Diagnostic Pasteur, France) was used on serum and cerebrospinal fluid to obtain a presumptive diagnosis and to monitor the course of the disease. Having failed conventional therapy with amphotericin B, the patient received compassionate treatment with voriconazole for a period of 37 days. High levels of voriconazole were observed in both serum and cerebrospinal fluid (CSF), with a trend toward accumulation. After 7 days a marked improvement in the patient's neurological symptoms was noted, and ELISA data indicated a corresponding decrease in Aspergillus galactomannan levels in both serum and CSF. Voriconazole was well tolerated, with only transient increases in ALT/AST recorded during therapy. Although the patient survived the acute Aspergillus infection, he subsequently died of an unrelated infection.
