Primary Outcome Measures:
  • clinical parameters cause of chronic kidney disease [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]

Enrollment: 14
Study Start Date: August 2008
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Diffuse Optical Spectroscopy
    near-infrared (NIR)
    Other Name: DOS
Detailed Description:

DOS have been shown to correlate with invasive measures of cardiac output, mean arterial pressure, blood loss, and blood hemoglobin concentration.

The researchers want to use DOS as a means to monitor volume changes during the hemodialysis treatment and to correlate the changes in volume and blood pressure with the measures of oxidative stress and inflammation used in this study.

The researchers want compared to a variety of laboratory parameters routinely measured in CKD subjects (GFR, proteinuria, Hg, serum albumin, bicarbonate, calcium, phosphorous, iron saturation, ferritin, lipid profiles, PTH) and to clinical parameters such as cause of CKD, blood pressure and dialysis-related parameters.
