Recurrence of hepatitis is a well-documented complication of hepatitis B liver disease, post-transplantation. It is well established also that the earliest hepatocellular change is the appearance of hepatitis B viral (HBV) markers and that the disease is rapidly progressive. In this article on 17 liver transplants in 16 HBV positive patients with long-term follow-ups (100-1234 days), the distinctive pathologic features of this disease are emphasized: the extreme viral load, the steatosis, and/or fibrosis. An attempt to quantitate the magnitude of the viral burden was made and the result was a staggering figure. In one patient, an estimated 10(18) HBV core particles were present in the liver. One of two patterns of progression were noted. In four patients in addition to the massive nuclear hepatitis B core antigen (HBcAg) and cytoplasmic hepatitis B surface antigen (HBsAg) positivity, superimposed hepatitic changes led to diffuse hepatic fibrosis (fibroviral hepatitis B); and in another six patients, extraordinary hepatocellular viral marker positivity and steatosis were the hallmarks (steatoviral hepatitis B). Steatosis is not usually considered a feature of HBV liver pathology. These results suggest that more than one type of posttransfusion recurrent hepatitis B liver disease exists pathologically.

UI MeSH Term Description Entries
D008103 Liver Cirrhosis Liver disease in which the normal microcirculation, the gross vascular anatomy, and the hepatic architecture have been variably destroyed and altered with fibrous septa surrounding regenerated or regenerating parenchymal nodules. Cirrhosis, Liver,Fibrosis, Liver,Hepatic Cirrhosis,Liver Fibrosis,Cirrhosis, Hepatic
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D011184 Postoperative Period The period following a surgical operation. Period, Postoperative,Periods, Postoperative,Postoperative Periods
D005234 Fatty Liver Lipid infiltration of the hepatic parenchymal cells resulting in a yellow-colored liver. The abnormal lipid accumulation is usually in the form of TRIGLYCERIDES, either as a single large droplet or multiple small droplets. Fatty liver is caused by an imbalance in the metabolism of FATTY ACIDS.

D006509 Hepatitis B INFLAMMATION of the LIVER in humans caused by a member of the ORTHOHEPADNAVIRUS genus, HEPATITIS B VIRUS. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact. Hepatitis B Virus Infection
D006515 Hepatitis B virus The type species of the genus ORTHOHEPADNAVIRUS which causes human HEPATITIS B and is also apparently a causal agent in human HEPATOCELLULAR CARCINOMA. The Dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum.
