title: Development of HIV encephalitis in AIDS and TNF-alpha regulatory elements.
abstract: Tumor necrosis factor-alpha (TNF-alpha) appears to play an important role in HIV encephalitis (HIVE). TNF2, a polymorphism of TNF-alpha, associates with higher levels of TNF-alpha and severe manifestations of some infections. We studied 44 acquired immunodeficiency syndrome (AIDS) patients with autopsy-proven HIVE and/or HIV leukoencephalopathy (HIVLE) (HIVE/LE) and 30 AIDS patients without HIVE/LE. TNF2 did not associate with presence of HIVE/LE (p > 0.5). Moreover, the TNF-alpha regulatory element TTATTTAT within the 3'-untranslated region was intact in HIVE/LE brains, and HLA-DR3 did not associate with HIVE/LE. Other host factors or, more likely, viral factors may be responsible for the development of HIVE/LE.
