ABSTRACT:   Dengue hemorrhagic fever (DHF) is a severe febrile disease, characterized by abnormalities in hemostasis and increased vascular permeability, which in some cases results in hypovolemic shock and in dengue shock syndrome. The clinical features of DHF include plasma leakage, bleeding tendency and liver involvement such as enlargement of the liver. During the peak period of outbreak from July through October, of 2005 and 2006, a total of 13 fatal cases of dengue hemorrhagic fever (DHF)/ dengue shock syndrome (DSS) were collected from Intensive Care Unit, Yangon Children Hospital to study their immunohistopathology of DHF. The liver seems to be a target for dengue virus, so postmortem examinations were performed to investigate histopathological changes and whether the virus and viral antigens were present in target cells of the liver. We detected Kupffer cell hyperplasia in 100%, hemorrhage in 92%, mixed midzonal and centrilobular necrosis in 85%, and hemophagocytosis in 77% by using hematoxylin and eosin stain of routine histopathological standard method. Dengue virus antigens of the structural (envelop) and non-structural (NS1) proteins were detected in 54% and 77% respectively in both hepatocytes and Kupffer cells, using immunohistochemistry. There was no recruitment of polymorphonuclear cells; however, minimal degree of portal infiltration by lymphocytes was detected in the liver lesions of patients who died from DHF. Thus, our findings conclude that the hepatocytes and Kupffer cells may be target cells supporting virus localization and replication to provide more information for understanding the pathogenesis of liver involvement in DHF.
