Efficacy of combination therapy with pegylated-interferon alfa-2a plus ribavirin in autoantibody-positive chronic hepatitis C patients / 中华肝脏病杂志

To evaluate the therapeutic efficacy of antiviral combination therapy with pegylated-interferon alpha-2a plus ribavirin (RBV) in patients with autoantibody-positive chronic hepatitis C (CHC) and to investigate the impact of the presence of autoantibodies on the treatment outcome. Eighty-six consecutive CHC patients who underwent a 48-week treatment regimen composed of Peg-IFNa-2a (135 or 180 mug/wk) plus weight-based RBV ( less than or equal to 65 kg, 800 mg/d; 65 to 75 kg, 1000 mg/d; more than or equal to75 kg, 1200 mg/d ). Prior to treatment (baseline) and at end of treatment (EOT; week 48), levels of antinuclear antibody (ANA), anti-smooth muscle antibody (SMA), anti liver/kidney microsomal antibody type 1 (LKM1), anti-La (SSB), and anti liver cytosolic-1 (LC-1) were detected by indirect immunofluorescence. At baseline, during treatment (weeks 4, 12, 24, and 36), EOT, and 24 weeks after EOT, levels of HCV RNA were assessed by real-time quantitative PCR. Rapid virological response (RVR) was defined as HCV RNA less than 10(3) copy/ml at week 4. Sustained virologic response (SVR) was defined as HCV RNA load below the lower limit of detection at 24 weeks after EOT. Correlation between autoantibodies and treatment-induced reduced HCV RNA load was assessed by univariate analysis of variance or chi-squared tests. Autoantibodies were detected in 24 patients, which included 14 ANA-positive patients, five SMA-positive patients, three LKM1-positive patients, one patient with double-positivity for ANA and SSB, and one patient with double-positivity for ANA and LC-1. The autoantibody-positive patients and autoantibody-negative patients showed similar rates of RVR (70.8% vs. 72.5%, P more than 0.05) and SVR (81.4% vs. 82.2%, P more than 0.05). Antiviral therapy with Peg-IFNa-2a RBV can effectively reduce the HCV RNA load in autoantibody-positive CHC patients; however, the presence of autoantibodies may not be an independent predictor of therapy outcome.

Primary hepatic diffuse large B cell lymphoma: a case report

In this report we describe a rare case of primary hepatic diffuse large B cell lymphoma in a 67-year-old man who presented with abdominal pain, deteriorated liver function, elevated lactate dehydrogenase. He was found to have diffuse nodular intrahepatic space-occupying lesion with normal alpha-fetoprotein and carcino-embryogenic antigen. The final diagnosis was made by percutaneous biopsy of the liver as the clinical manifestation not consistent with common liver diseases. The patient was treated with R-CHOP [rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone] without surgical resection with a favorable response. However, serious and complication was occurred after 4 cycles of chemotherapy, and the patient finally died of concurrent acute respiratory distress syndrome
