Chronic Active Hepatitis B with HBV-Associated Nephropathy: Close Resemblance to Lupus Nephritis

We present a rare case of a 23-year-old male incidentally detected with hepatitis B virus (HBV) infection presenting with features suggestive of HBV-associated nephropathy. A renal biopsy specimen suggested a mesangioproliferative glomerulonephritis with a full-house pattern on immunoflourescence consistent with a diagnosis of diffuse lupus nephritis. Glomerular HbeAg and HbsAg antigens were not detectable by immunofluorescence. Antiviral therapy was instituted to suppress viral replication, thereby leading to clinical and virological remission, including that of the glomerulonephritis, without the need for additional immunosuppressant therapy. This case depicts the uniqueness of the presentation of the two conditions mimicking each other, the strategy adopted to prevent the activation of viral replication and the achievement of clinical remission.

Successful Treatment Using Simeprevir, Sofosbuvir and Rituximab of a Severe Form of Hepatitis C Virus-related Mixed Cryoglobulinemia with Cardiac Involvement

Numerous extrahepatic manifestations have been reported in hepatitis C virus (HCV) infection, particularly mixed cryoglobulinemia (MC). MC generally responds to clearance of HCV under pegylated-interferon plus ribavirin treatment. New direct-acting antiviral agents have been licensed for HCV under different combinations but have not been studied in severe forms of MC. Here, we present a case report describing a life-threatening form of MC with multivisceral involvement, which was successfully treated with concomitant rituximab, sofosbuvir and simeprevir. In light of the rapid clinical remission associated with sustained virological response and the excellent side-effect profile, this treatment should be considered as a first-line therapy in severe forms of MC.

Parotid gland oncocytoma in HCV-positive patient with non-Hodgkin's lymphoma. Case report

We report a case of parotid gland oncocytoma in a patient with chronic infection from hepatitis C virus (HCV) and associated non-Hodgkin's lymphoma and xerophthalmia. Our case confirms the triple tropism of the HCV: hepatotropism, lymphotropism and sialotropism.
