Brief summary
We hope to study components within the blood that may predict success, failure or other associated complications in relation to the type of vascular access being used.
Detailed description
Renal failure affects more than 350,000 patients in the United States. All patients undergoing dialysis must have access to the vascular system (blood stream) for hemodialysis treatment. Methods of access include a catheter, or tube, that goes through the skin and into a large vein, a surgically created connection of a vein to an artery called an AV fistula, or a surgically created connection of a vein to artery using a graft or plastic tube. Previous research has shown considerable differences in the function and success in these types of vascular access for dialysis. Research investigators try to explain these differences and find the causes and explanations for the variations seen in vascular access. Forty patients undergoing dialysis treatment will be evaluated by analyzing serum specimens obtained during outpatient hemodialysis access. Serum will also be collected from ten pre-dialysis patients and ten normal volunteers for comparison. Pre-dialysis patients are those who have Stage 3, 4, or 5 chronic kidney disease but are not yet on dialysis and have never had any type of created vascular access. Normal subjects will have no kidney disease, autoimmune disorders, recent (\<6 months) chemotherapy treatment or corticosteroid use, or other chronic condition determined by the investigator to interfere with cytokine and inflammatory markers. The serum specimens will be analyzed for cytokine/inflammatory markers and correlated with clinical access type and other medical data and demographic information.
Interventions
PROCEDUREBlood Draw
For patients undergoing routine hemodialysis for chronic renal failure, 5-10 ml of blood will be removed from the dialysis tubing during vascular access. All other subjects will have 5-10 ml of blood drawn by routine venipuncture.
