Active clinical trials for "Kidney Diseases"

The main aim of this study is to compare the renal function (serum creatinine at 6 months) in the later introduction of tacrolimus or rapamycin based in immunosuppressor regimes with daclizumab, mycophenolate mofetil, and steroids in patients older than 50 years of age who are the recipients of a graft from donors aged 55 years and older.

Much more about kidney disorders can be learned by determining kidney function. This research proposes to study the kidneys function by several parameters known as glomerular filtration rate (GFR), Renal Plasma Flow (RPF), and Glomerular Capillary Wall Permselectivity. The study will select patients suffering from different types of kidney diseases. These patients will be selected based on the presence of significant amounts of protein in their urine (proteinuria). Standard blood and urine tests are often unable to provide completely accurate information about the kidney. In order for researchers to have a more accurate idea of kidney function, they will use alternative tests. Test materials (para aminohippurate and inulin) will be injected into patients veins that provides information based on their filtration through the kidneys....

Ticagrelor, a new P2Y12 receptor antagonist, achieve faster, consistent and higher platelet inhibition than clopidogrel, which was considered more noticeable in patients with ACS combining chronic kidney disease(CKD). Nonetheless, the pharmacokinetic properties of ticagrelor in the patients with CKD and NSTE-ACS has not been thoroughly studied. This study was designed to provide PK and PD data of ticagrelor compared with clopidogrel, in order to estimate that ticagrelor is superior to clopidogrel in getting better inhibition of platelet in patients with CKD and NSTE-ACS. P2Y12 inhibitor naïve patients with CKD (eGFR < 60 ml/min/1.73m2 ) and NSTE-ACS will be enrolled in this single-center, prospective, randomized, parallel-control study and randomly assigned in a one-to-one ratio to receive ticagrelor or clopidogrel on top of chronic aspirin treatment. The primary endpoint was the PRU by Verify Now at 30 days after loading dose.

The aim of the investigators work is to describe the urodynamic results in the CKD (chronic kidney disease) grade 4 patients and to verify observations that urinary catheter may improve kidney function in those patients. 100 patients with CKD grade 4 will do urodynamic examination. All patients will be randomized into two groups / the intervention group that will be inserted urinary catheter for 2 weeks and the follow up group. Kidney function will be monitored by creatinin values and the investigators will measure the time to dialysis in the two groups.

Frailty is a syndrome characterized by decreased reserve and diminished resistance to stressors. The proposed research will evaluate the association of frailty with chronic kidney disease (CKD). The prevalence of frailty increases with age and with CKD, but studies are needed to determine whether frailty is associated with worsening of CKD and whether intervention to treat frailty can improve physical functioning and health-related quality of life (HRQOL) as well as slow progression of CKD.

Older patients with chronic renal failure suffer from sarcopenia. Loss of muscle function is associated with increased morbidity and mortality. Currently few treatment are available. The aim of this study is to evaluate the impact of physical rehabilitation in this population on muscle performance and quality of life.

Prospective, randomized, comparative clinical and open-label trial comparing sodium bicarbonate catheter lock solution (SBCLS) to normal saline catheter lock solution (NSCLS) use in HD patients with central venous catheters (CVC).

Immunoglobulin A nephropathy (IgAN) is the most common glomerulonephritis worldwide. IgAN is progressive, particularly when patients have a significant proteinuria (proteinuria >1g/g creatinine), impaired kidney function, or elevated blood pressure. In 10 years, nearly 20-40% of these IgAN patients progress to end-stage renal disease (ESRD). Early IgAN is tentatively defined when proteinuria is insignificant and kidney function and blood pressure are normal. Patients with early IgAN rarely progress to ESRD. However, 30-40% of patients with early IgAN ultimately developed a significant proteinuria and hypertension in 10 years. Therefore, earlier intervention may be needed if it can prevent the development of a significant proteinuria and hypertension. Since angiotensin ll receptor blocker (ARB) is drug of choice in reducing proteinuria and controlling blood pressure, the investigators hypothesized that early introduction of ARB may be beneficial in preventing the significant proteinuria development in early IgAN patients. To prove the hypothesis, the investigators plan the current interventional study.

With the present study the investigators will evaluate the benefit of end-ischemic HOPE on ECD grafts (livers and kidneys) as compared to SCS. Organs will be perfused through a recently developed machine perfusion (MP) device, from the beginning of back-table procedures till implantation, without increasing CIT. The aim of the study will be demonstrating the ability of HOPE to improve graft function and post-operative outcomes of ECD kidney and liver recipients.

It's a pilot study with an open label randomized-controlled design. Estimated number of patients should have been 38, taking in account of a maximal drop out up to 20% of the sample. We enrolled 35 patients, 27 of whom terminated the study as per protocol (14 in the Low protein (LP) group and 13 in the Normo Protein (NP) group). Patients were treated for six months with two different dietary prescriptions: LP group (n=17) was prescribed high calories/low proteins diet (30 Kcal/kg and 0.6-0.7gr/kg respectively). In order to assure prescribed calorie intake, this group was supplemented with commercial protein free products (protein content <2%). NP group (n=18) was prescribed high calories/normal proteins diet (30 kcal/kg and 0.8 gr/kg respectively). The primary hypothesis of the study was that in CKD patients at risk of malnutrition (4 ≤ MIS ≥7) with a persistent spontaneous low protein and calories intake, the prescription of a LP diet was not inferior to NP diet regarding the development of malnutrition (i.e.MIS ≥ 8). We also wanted to test whether in these patients, the prescription of a LP diet was superior to the NP comparator regarding the control of the metabolic complication of chronic kidney diseases (i.e hyperphosphatemia, inflammation and metabolic acidosis), the progression on dyna/sarcopenia, inflammation and possibly on the progression of renal disease itself.
