Background: The presence of the adhesion molecules intercellular adhesion molecule-1 (ICAM-1) and soluble vascular cell adhesion molecule-1 (VCAM-1) is associated with elevated risk of cardiovascular disease. Subjects with human immunodeficiency virus (HIV) disease have multiple risk factors for cardiovascular disease, including elevated serum lipid levels, insulin resistance, and elevated levels of ICAM-1 and VCAM-1. This study assessed the variables associated with elevated adhesion molecule levels in this patient population.

Experimental Design: Sixty-five subjects received fMRI scans while passively viewing angry, fearful, happy, and neutral facial stimuli. Subjects also completed a trait anxiety inventory, and were monitored using ambulatory wake ECG.

The expression of selected gene products involved in cell differentiation and cell growth and genetic polymorphism of detoxifying genes was examined in 105 surgically resected nonsmall cell lung cancer (NSCLC) patients, and the relationship of these factors was correlated with cigarette smoking and patient survival. Genotyping of peripheral blood lymphocytes from 87 patients was performed for CYP2E1, GSTM1, GSTT1, mEH, and MPO detoxifying genes using polymerase chain reaction. Formalin-fixed, paraffin-embedded tissue was immunostained with antibodies to p53, p27, phospho-AKT, and bcl-2 using the avidin-biotin-peroxidase method and tissue microarray technique.

There is a theoretical possibility that hemodialysis (HD) therapy in these patients may enhance HIV replication through the activation of white blood cells and release of such cytokines as tumor necrosis factor-alpha, interleukin-1, and interleukin-6, which have been found to increase HIV replication in vitro. We therefore determined whether dialysis modality is a factor in the survival of patients with HIVAN and ESRD.

In the last decade, survival of HIV-infected patients in the United States has remarkably improved. To determine whether similar improvement in survival has occurred in HIV-infected dialysis patients, their survival was evaluated by using the United States Renal Data System database.
