Hepatitis in children with acquired immune deficiency syndrome. Histopathologic and immunocytologic features.
Hepatic morphology and immunocytology were evaluated in 4 children with clinical and immunologic characteristics of the acquired immune deficiency syndrome or acquired immune deficiency syndrome related complex. All 4 children had hepatomegaly and increased serum alanine and aspartate aminotransferase activity. Both lobular and portal changes were noted. Lymphocytic infiltration, piecemeal necrosis, hepatocellular and bile duct damage, sinusoidal cell hyperplasia, and endothelialitis were prominent. Vesicular rosettes in sinusoidal lymphocytes and tubuloreticular structures in sinusoidal endothelial cells were demonstrated by electron microscopy. The lymphocytic infiltrate in both the lobular and portal spaces was characterized by a relative increase of cytotoxic/suppressor (T8) cells. Hepatitis may be a common feature of pediatric acquired immune deficiency syndrome and acquired immune deficiency syndrome-related complex. Although the histopathologic changes are consistent with chronic active hepatitis, the specific pathogenesis remains to be determined.
