We reported a case of reversible posterior leukoencephalopathy syndrome (RPLS) that occurred during cyclosporin A (CyA) therapy for fulminant hepatitis. A 22-year-old man was given an intravenous drip of interferon-beta, metylprednisolone sodium succinate and CyA, and also received plasma exchange and hemodiafiltration. On the 7th day of the intravenous CyA therapy, in which its dose had been increased from 60 mg/day to 84 mg/day, he became somnolent and had headache, double vision, hallucination and then a generalized tonic-clonic seizure. The blood CyA concentration increased to a level as high as 455 ng/ml. Brain computed tomography (CT) scan without contrast medium revealed symmetric low-density areas in the bilateral occipital white matter and partly in the cortex. T2-weighted magnetic resonance imaging (MRI) showed an increased signal intensity, and single-photon emission CT using 99 mTc showed a hypoperfusion of cerebral blood flow in those areas. After CyA administration was changed to 100 mg/day orally to decrease its uptake in the blood, his consciousness and vision recovered within 4 weeks. Then abnormalities in MRI findings completely disappeared. On the basis of the clinical course and time-sequential change of serum CyA level in this patient, he was diagnosed as having RPLS caused by CyA therapy. Recently, the number of cases of RPLS has increased in the Western countries. However, there are few reports of RPLS after CyA therapy in Japan. From this case, we emphasize that careful following up the patient's neurological findings during CyA therapy is very important and that a cranial MRI is an essential tool for the diagnosis of RPLS.

A 31-year-old man referred to our hospital for treatment of his chronic myeloid leukemia (CML) in the first chronic phase by bone marrow transplantation. We pretreated him with cyclophosphamide and total body irradiation and bone marrow transplantation (BMT) was carried out. On day 31, the engraftment was confirmed and on day 52, acute graft versus host disease (GVHD) was observed. On day 189, he lost consciousness due to cyclosporine A-induced leukoencephalopathy and 375 mg cyclosporine A was changed to 100 mg prednisolone. On day 199, liver dysfunction (AST 410 IU/L, ALT 557 IU/L, gammaGTP 385 IU/L, ALP 363 IU/L, D-Bil 0.3 mg/dl) developed and a liver biopsy was performed. PCR analysis of DNA from the liver biopsy specimen was positive for HHV-6 and immunostaining using anti-HHV-6 and anti-HHV-6b antibodies showed positive staining in the cytosol of hepatocytes. No other viruses were found to induce hepatitis. From these results, he was diagnosed as having HHV-6 hepatitis and it was successfully treated with gancyclovir (GCV) administration.

Sickle cell disease (SCD) frequently affects the liver; if acute liver failure (ALF) develops, the only potentially effective therapeutic option is liver transplantation (LT). Only 12 patients for whom LT was performed for SCD-related ALF have been described so far. We report a retrospective series of 6 adult patients with SCD (3 men and 3 women, median age = 40.1 years) who underwent emergency LT. The indication for LT was ALF complicating cirrhosis in 5 patients (hepatitis C/iron overload-induced cirrhosis in 3 and iron overload-induced cirrhosis in 2); one patient had autoimmune hepatitis. The median follow-up was 52.7 months (0.5-123 months). The 1-, 3-, 5-, and 10-year survival rates were 83.3%, 66.7%, 44.4%, and 44.4%, respectively. One patient died of hepatocellular failure precipitated by hyperacute allograft rejection on post-LT day 10. Soon after LT, 2 patients developed seizures; in 1 case, the seizures were a complication of early calcineurin inhibitor-induced leukoencephalopathy. Four long-term survivors benefited from specific management of SCD; specifically, the hemoglobin S fraction was maintained below 30% and the total hemoglobin level was maintained between 8 and 10 g/dL. Two patients had mild vaso-occlusive crises. Three patients experienced a recurrence of hepatitis C virus (HCV) infection; 2 of these patients experienced reversible neurological complications while they were receiving antiviral treatment. Carefully selected patients with SCD may benefit from emergency LT. However, such patients seem to be particularly susceptible to neurological complications after LT. In contrast, severe SCD-related crises do not seem to recur if specific management is provided. Outcomes may be improved if the neurological complications can be minimized; for example, the administration of a calcineurin inhibitor can be delayed, and the management of HCV infection recurrence can be improved.
