Non responders to interferon therapy among chronic hepatitis patients infected with hepatitis C virus.

We studied a series of 268 chronic hepatitis C patients (31 chronic persistent hepatitis CPH, 69 mild chronic active hepatitis CAH, 125 severe CAH, and 43 active cirrhosis) enrolled from 1988 to 1991 in different therapeutic protocols using lymphoblastoid or recombinant interferon (IFN) at a dosage of 3 mega units (M.U.), three times a week for 12 months. Of these patients 54.8% showed a complete response (normalization of aminotransferases), 14.2% a partial response (decrease in aminotransferases of over 50%), 27.6% no response, and 3.4% a substantial progressive increase in the liver enzymes during IFN (becoming worse). The prevalence of non responders was lower in CPH (9.7%) than in CAH patients (31.9% in the mild form and 20.8% in the severe), and significantly higher in patients with cirrhosis (53.5%). No correlation was observed between non response and the baseline aminotransferase level or the patient's sex. Patients under 35 had a better response to IFN when compared with patients 36-50 years. This is probably due to the higher prevalence of CPH patients with a good response to IFN in the youngest group. No effect was gained in non responders by increasing the dose or shifting from recombinant to lymphoblastoid IFN; three patients were then treated with steroids, but only one benefitted. For 5 of the 9 patients who became worse, steroids were started after discontinuation of IFN therapy, and they induced a favorable response only for the 3 who had developed autoantibodies during IFN treatment.

Fatal, complete splenic infarction and hepatic infection due to disseminated Trichosporon beigelii infection: CT findings.

We report on a 56-year-old woman with acute lymphocytic leukemia who presented with right upper quadrant pain, fever, nausea, and vomiting. Laboratory studies confirmed fungemia with Trichosporum beigelii, and contrast-enhanced computed tomography of the abdomen demonstrated numerous low-attenuation liver lesions and a hypodense spleen with capsular enhancement suggestive of complete splenic infarction. Subsequent splenectomy confirmed that the spleen was completely infarcted and infiltrated with Trichosporum. The patient had a difficult postoperative course and died despite aggressive antifungal therapy.

Reactivation of latently infected hepatitis B virus in a leukemia patient with antibodies to hepatitis B core antigen.

A 66-year-old man with chronic B-cell leukemia who had antibody to hepatitis B core antigen (anti-HBc) but not hepatitis B surface antigen (HBsAg) suffered from lethal hepatitis caused by hepatitis B virus (HBV) reactivation. He initially lacked circulating viral genomes in his sera and did not have a past history of liver dysfunction. In this patient, the immunosuppressive condition introduced by disease progression of leukemia induced reactivation of dormant HBV, and the withdrawal of chemotherapy resulted in fatal liver failure. Mutation-specific assay based on competitive polymerase chain reaction (PCR) and sequencing analyses revealed the predominant reactivation of an HBV strain with missence mutation (point mutation G-to-A at nucleotide 1896) in the precore regions, as well as point mutations in the core promoter regions. Therefore, it is important to note the risk of HBV reactivation, with resulting lethal hepatic failure, in anti-HBc-positive healthy individuals, even when they lack HBsAg. who receive immunomodulating therapy.
