Active clinical trials for "Kidney Failure, Chronic"

The objective of this study is to determine the extent and magnitude of the pharmacokinetic drug interaction between mycophenolate mofetil (MFF) (under Css conditions) in the presence of iron in renal transplant recipients. A two phase pharmacokinetic study will be conducted to determine the bioavailability of MMF (under steady state, Css, conditions) in the presence of two commonly prescribed iron formulations (polysaccharide iron complex and sustained release ferrous sulfate) in renal transplant recipients. This study will evaluate valuable clinical information to help better guide the appropriate utilization of the following formulations and dosing strategies: Polysaccharide iron complex concomitant administration with MMF, Sustained release ferrous sulfate concomitant administration with MMF, Dose separation (2 hours) between MMF and iron (polysaccharide iron complex or sustained release [S.R.] ferrous sulfate)

Homocysteine (Hcy) and asymmetric dimethylarginine (ADMA) have recently been recognized as potential risk factors for atherosclerosis in the general population, and the metabolism of each of these substances seems to be closely related. This study investigates the association between these substances, and whether elevated serum levels of Hcy and ADMA would be related to a high risk of atherosclerosis and cardiovascular events in maintenance hemodialysis (HD) patients.

To investigate whether traditional risk factors and novel risk factors predict higher risk of atherosclerotic cardiovascular disease (ASCVD) in a prospective study of incident dialysis patients.

The objective of the current study is to evaluate the compliance to blood pressure measurements' recommendations in dialysis centers. The idea is to address a questionnaire to physicians, head nurses and patients in order to probe the way to measure blood pressure. The objective is to face the theoretical guideline with what is effectively done.

Open label, randomized, cross-over clinical study comparing the acute effect of high versus low protein meals during dialysis on intradialytic blood pressure, 24-hour ambulatory blood pressure and arterial stiffness indices on maintenance hemodialysis patients.

The aim of the project is to check if there is a possibility for a nephrologist to visualise the guidewire by means of available ultrasound scanners. To evaluate that, the procedure of catheter insertion will be expanded by ultrasound examination of right atrium and inferior vena cava border using substernal view. Such imaging seems to ameliorate the safety of catheter implementation and could be a good alternative for fluoroscopy, eliminating its adverse effects.

Acute Renal Failure (ARF) is defined by a severe, and usually reversible, glomerular filtration rate decreasing. Acute Tubular Necrosis (ATN) remain the major cause of ARF involving distress and destruction of tubular cells. This specific typology of ARF may evolve toward Chronic Renal Failure (CRF) concretizing a major public health issue. Predict the progression of ARF towards CRF appears essential. The investigators believe that the PIIINP and urinary NGAL biomarkers may constitute robust biomarkers of progression risk towards CRF.

Patients on haemodialysis are at higher risk of getting a severe form of COVID-19 if they become infected. Vaccinations are soon to arrive and offer great hope of controlling the current pandemic. It is likely that patients on haemodialysis will be amongst the first people to be offered vaccination against COVID-19 when they become available. While any vaccines offered to these patients will be safe to receive, the effectiveness of the vaccines at giving immunity to being infected with COVID-19 are not known as they have not been explicitly tested in patients on haemodialysis. This study will involve having 3 blood tests to test for an antibody response following vaccination for COVID-19. The first will be 1 month after the first vaccination dose to look at the initial antibody response and the second and third will be 1 month and 6 months after the second vaccination dose.

The FDA approved the antiviral drug remdesivir for use in adults for the treatment of COVID-19 requiring hospitalization. There are only limited data about the safety of the drug in hemodialysed patents. Chronic kidney disease is a risk factor in COVID-19 for developing severe disease. The aim of our investigation is to observe the safety of remdesivir among hemodialysed patients requiring hospitalization for COVID-19. We are going to compare two group's data: Hemodialysed COVID-19 patients requiring hospitalization because of pneumonia and need of oxygen supplementation, and admitted after 12/Apr/2021 - these patients received remdesivir. Hemodialysed COVID-19 patients requiring hospitalization because of pneumonia and need of oxygen supplementation, and admitted before 12/Apr/2021 - these patients did not receive remdesivir.

The aim of the study is to evaluate the prevalence of LUTS in patients with moderate to severe (Stage IIIb), severe (Stage IV) CKD and ESRD : Stage V CKD) without renal transplantation (both pre-dialysis and dialysis patients). The study will also investigate the correlation between the diuresis, functional bladder capacity and LUTS in this population. By means of the obtained results, the investigators hope to be able to predict at which values of diuresis and functional bladder capacity these patients will start to develop LUTS. The investigators will also evaluate the impact of LUTS on the quality of life of these patients.
