Hepatic expression of hepatitis B and delta virus antigens in patients with acute and chronic hepatitis.

Delta antigen (delta-Ag), hepatitis B surface antigen (HBsAg) and hepatitis B core antigen (HBcAg) were examined by immunofluorescence and immunoperoxidase staining in 106 deparaffinized liver biopsy samples from HBsAg-positive patients with acute and chronic hepatitis. The delta-Ag was present in 15 cases (14%), with nuclear positivity varying greatly in intensity and prevalence. Patients with chronic hepatitis associated with delta infection had a histological picture characterized by foci of intralobular inflammation, many apoptotic bodies and shrunken hepatocytes with no satellite signs of inflammation. The histological pattern of delta antigen-positive acute hepatitis was characterized by the presence of a large number of intralobular apoptotic bodies. The inflammatory reaction mainly involved the portal tracts with piecemeal necrosis, but without collagen production. In the same cases the pattern of expression of HBsAg and HBcAg was unusual: in three cases HBcAg and HBsAg were concomitantly present, whereas in one case none of the hepatitis B virus markers was detectable.

Adult metachromatic leucodystrophy: clinicopathological report of two familial cases with slow course.

Two cases of adult metachromatic leucodystrophy in one family are reported. The main clinical features in both were predominantly psychiatric with alcoholism and an extremely long duration of the illness. Neuropathological examination revealed a similar distribution of the lesions in both, and scanty metachromatic accumulation in the CNS and not at all elsewhere. The great variability of the lengths of the courses is stressed. The duration in no way seems to be linked to the age of onset, except in the typical infantile form. The authors argue that different lengths of history correlate with distinct neuropathological findings, and may possibly be related to qualitative differences in the involved enzyme disturbance. Therefore, the authors suggest that the classification based on the age of onset be enlarged with a further one distinguishing between 'rapid' and 'slow' course types.
