This study will evaluate in patients with kidney disease, the role that certain inflammatory and immune mediators play in promoting kidney damage. The investigators hypothesize that certain mediators, (identified in the serum, urine and renal biopsy tissue), of patients with a variety of different renal disease states will provide information regarding their clinical course and that inflammatory and immune patterns in the serum and urine of patients with kidney disease may yield predictive diagnostic information in place of a renal biopsy. The ability to detect and quantify these mediators may lead to earlier detection and treatment of kidney disease in order to prevent kidney failure and the requirement for renal replacement. The study will evaluate serum, blood and urine collected over a one year period post kidney biopsy for the presence of inflammatory or immune mediators, which will be correlated with kidney pathology findings (gene signatures). These gene signatures will be compared to "normal" control specimens obtained from donor transplant kidneys or from normal kidney tissue obtained from patients who require their entire kidney removed for a tumor.
