Adenovirus hepatitis in a patient with severe combined immunodeficiency.

An autopsy case of adenovirus hepatitis with severe combined immunodeficiency (SCID) is presented. A 7-month-old female was admitted to the Kitasato University Hospital with chief complaint of persistent fever. A diagnosis of severe combined immunodeficiency (SCID) was made because of defective function in both T and B lymphocytes. Respiratory disturbance and severe hepatic dysfunction were manifested after admission. She died of respiratory failure on the 40th hospital day. Autopsy findings revealed many focal necroses scattered irregularly throughout the liver. Degenerating hepatocytes around the focal necrosis contained nuclear inclusion bodies, and crystalline arrays of adenovirus virions were recognized in these cells by electron microscopy. Adenovirus antigens were brilliantly detected in the nuclear inclusion bodies by indirect immunofluorescence.

Thyroid antigen-antibody nephritis: possible involvement of fucosyl-GM1 as the antigen.

Hyperthyroidism, microscopic hematuria, and proteinuria developed in an 11-year-old girl. Proteinuria decreased during treatment of hyperthyroidism with an antithyroid drug. On admission, serum anti-thyroglobulin antibody, antimicrosomal antibody, and immune complex were present. The thyrotropin binding inhibitory immunoglobulin (TBII) level was low. On the other hand, an antibody to the ganglioside component (fucosyl-GM1) was detected by an enzyme linked immunosolvent assay (ELISA). A thyroid biopsy specimen showed massive lymphocytic infiltration and interstitial fibrosis. A renal biopsy specimen showed marked proliferation of mesangial cells and increased mesangial matrix with focal segmental capillary wall abnormality. Electron microscopec studies demonstrated mild paramesangial dense deposits. By indirect immunofluorescence, granular glomerular basement membrane and mesangial staining were not detected with rabbit antibody to thyroglobulin, but were detected with rabbit antibody to fucosyl GM1. Fucosyl GM1 was also seen along the basilar aspect of the thyroid follicular epithelial cells. These observation suggests the development of glomerulonephritis mediated by thyroid antigen, particularly ganglioside component.
