Filter by:The investigators will determine the feasibility, safety and efficacy of intravenous sodium bicarbonate in reducing progression to overt acute renal failure in patients with the systemic inflammatory response syndrome, and low urine output or early acute renal impairment as defined by serum neutrophil gelatinase-associated lipocalin (NGAL).
This is a randomized, controlled, double-blind, multicenter multinational safety study involving about 300 predialysis patients aged 18 years or above suffering from anemia. Symptomatic anemia will be corrected by s.c. application of EPO HEXAL or ERYPO® in order to achieve a hemoglobin target range of 10.0 -12.0 g/dL.
Hypothesis: Free light chain removal haemodialysis will increase the rate of renal recovery in patients with cast nephropathy, severe renal failure and de novo multiple myeloma. This study will randomise patients with multiple myeloma and severe renal failure to treatment to remove free light chains by haemodialysis or not.
The are 2 principal goals in this study: 1. To measure plasma copeptin levels in healthy subjects and to correlate them with plasma AVP concentrations and urine osmolalities in iso-, hypo-, and hyperosmolar states. 2. To measure plasma copeptin concentrations in patients with chronic renal failure under the same conditions described above, in order to characterize the impact of renal function on circulating copeptin levels in correlation to plasma AVP and urine osmolality.
This study aims to compare the performance of the tuberculin skin test, used for more than 50 years as a diagnostic tool for latent tuberculosis infection, with 2 blood tests which have recently become commercially available (Interferon-gamma release assays) in a population of immunosuppressed individuals with chronic renal failure undergoing long term hemodialysis
A not randomized , cross sectional study will be done to determine the possible association of coronary artery calcification (CAC) score assessed by multirow spiral computed tomography (MSCT) with specific and non specific uremic factor of vascular calcification.
The purpose of this randomized trial was to determine whether renal perfusion with cold blood provides better protection against renal ischemia than perfusion with cold crystalloid in patients undergoing TAAA repair with left heart bypass.
Cardiovascular related disease is the main cause of death in patients with kidney disease, and "oxidative stress" is thought to be a major contributor by promoting thickening of the heart muscle and stiffening of the arteries. Allopurinol, a drug used safely in the treatment of gout for many years, has been found to dramatically reduce "oxidative stress". It is therefore hoped that it also reduce the thickened heart muscle and stiffened arteries. If it did, it is likely to reduce the appallingly high cardiac death rate in this group of kidney disease patients.
The influence of hemodialysis on oxidative stress, endothelial activation, inflammation and on the redox state of lymphocytes should be clarified as well as the putative relationships between all these parameters.
After transplantation, if insufficient immunosuppression is achieved, rejection and graft loss follows. If to much immunosuppression is given, the patient suffers risk for infections and malignancies. Despite careful dosing and monitoring of drug levels, the biological effects of the immunosuppression given is difficult to predict and varies significantly. As a result, the degree of immunosuppression (or immunosuppressive status) remains unknown and clinical problems related to under- or over-immunosuppression are common. Thus, a method to determine the degree of immunosuppression would be of great and direct clinical importance and the results would be improved. T cells are the principal cells of the immunesystem causing rejection. Furthermore, all immunosuppressive regimes targets T cells. Thus, T cell reactivity could reflect the biological effects of the immunosuppression and the immunosuppressive status. In addition, T cells are of crucial importance in the immunedefence against viral diseases. Therefore, data on virus specific T cell reactivity could aid in diagnosis, monitoring and treatment of viral disease. The proposed study aim to develop a clinically useful method to monitor cellular immunity and the degree of immunosuppression after transplantation by determinations of the specific T cell reactivity to several clinically relevant viruses.
