Dendritic cell deficiency associated with development of BK viremia and nephropathy in renal transplant recipients.

Background: BK virus nephropathy (BKVN) is a significant cause of renal allograft loss. Although overall intensity of immunosuppression is the greatest risk factor, recipient immune factors likely also play a role in the pathogenesis. Dendritic cells (DC) are potent antigen-presenting cells important for the induction of anti-viral cytotoxic T-cell responses.

Prevalence of transaminase abnormalities in asymptomatic, healthy subjects participating in an executive health-screening program.

The objective of this study was to characterize the prevalence of asymptomatic liver transminase (LT) abnormalities in a healthy, low-risk adult population and identify associated risk factors. We reviewed 2340 completed medical records of participants in our Executive Health Program, which provided screening medical evaluations for executives. LT (alanine aminotransferase and aspartate aminotransferase) were considered abnormal if they above normal range for our laboratory.
