Potential Effect of Dialyzer Leaching of BPA From the Fresenius Optiflux 160NR Compared to the Nipro ELISIO-15H

Exclusion Criteria

• •Participation in another study which may interfere with the planned study
• •Active infection
• •Medical conditions which may interfere with the study (unstable cardiac status, chronic liver disease, active hepatitis as defined by elevated liver enzymes)
• •Females (It is expected that potential changes in estrogenic activity that might be seen in patients exposed to BPA will be modest and would be masked by naturally occurring variability of estrogen activity in women at varying stages of gonadal activity (pre, post-menopausal, different points in menstrual cycle, eventual pregnancy, etc). Thus, limiting study to adult males will maximize the possibility of detecting any changes in estrogenic activity.)
