Hepatic involvement in Wegener's granulomatosis: a case report

<p>Abstract</p> <p>Introduction</p> <p>We report the case of a 58-year-old Caucasian Greek man who presented with dry cough, fever, bilateral alveolar infiltrates and acute hepatitis.</p> <p>Case presentation</p> <p>After a lung biopsy, the patient was diagnosed with Wegener's granulomatosis. The diagnosis was supported by the presence of anti-proteinase-3 anti-neutrophil cytoplasmic antibodies. A liver biopsy demonstrated the presence of mild non-specific lobular hepatitis and periodic acid-Schiff positive Lafora-like inclusions in a large number of his liver cells. The patient was treated with prednisone and cyclophosphamide, which was followed by subsequent remissions of chest X-ray findings and liver function studies.</p> <p>Conclusion</p> <p>What makes this case worth reporting is the coexistence of liver inflammation with a biochemical profile of severe anicteric non-viral, non-drug induced hepatitis coinciding with the diagnosis of Wegener's granulomatosis. Our paper may be the first report of hepatic involvement in a patient diagnosed with Wegener's granulomatosis. The aetiological link between the two diseases is supported by the reversion of hepatitis after the immunosuppression of Wegener's granulomatosis. We favor the hypothesis that hepatic vasculitis may be the cause of acute hepatocellular necrosis.</p

Occult hepatitis B virus infection in Greek patients with chronic hepatitis C and in patients with diverse non-viral hepatic diseases

Occult hepatitis B virus (HBV) infection has been reported in patients with chronic hepatitis C who are negative for HBV surface antigen (HBsAg). However, the significance of 'silent' HBV in hepatitis C virus (HCV) infection is unknown. We investigated 540 subjects for the presence of occult HBV in Greek HCV patients, patients with nonviral liver diseases and healthy donors in an attempt to determine the frequency and importance of this phenomenon. One hundred and eighty-seven anti-HCV(+)/HBsAg(-) patients' sera were investigated for the presence of HBV-DNA by polymerase chain reaction. Two hundred and eighty-two selected blood donors (positive for antibodies to HBV core antigen) and 71 patients with various nonviral hepatic diseases consisted the control groups [both controls were anti-HCV(-)/HBsAg(-)]. HBV-DNA was detected in 26.2% of HCV-infected patients vs 8.5% of patients with nonviral diseases (P = 0.003) and 0/282 of donors (P = 0.0000). HBV-DNA was neither associated with HBV markers, nor with the clinical status of HCV and nonHCV patients. Neither epidemiological, histologic and virologic data nor the response to therapy were associated with the HBV-DNA detection. Hence one quarter of HCV-infected patients had occult HBV infection. Similar findings were not found in both control groups. Occult HBV infection in Greek patients with chronic hepatitis C does not seem to modify the progression of chronic liver disease. Further studies of longer duration are needed in order to clarify the role of 'silent' HBV infection in HCV-infected patients
