Filter by:Tenofovir disoproxil fumarate (TDF) is one of the most frequently used drugs to treat HIV. Long term use of TDF can induce renal toxicity. Tenofovir alafenamide (TAF) is a new pro-drug of Tenofovir which has not been associated with renal toxicity and may therefore be a good substitute for TDF in patients with TDF induced renal toxicity. Abacavir (ABC) is another drug that can be used for the treatment of HIV and is not associated with renal toxicity. In this study the investigators will compare the effect on renal function of a switch from TDF to TAF with a switch from TDF to ABC in patients with TDF induced renal insufficiency.
Iodinated contrast media are now frequently used in diagnostic imaging exams, including pediatrics. In adults, the acute renal failure (ARF) associated with contrast agents (CA-AKI) occur in 3-33% of exposed patients, especially as the patient is fragile, has comorbidities or pre-existing renal aggression . In children, the prevalence of this little known disease is probably underestimated. The investigators intend to conduct a prospective epidemiological study, to estimate the impact of the acute renale failure to iodinated contrast agents in pediatrics.
The purpose of this study is to find out why patients with chronic kidney disease (CKD) have poor exercise capacity and to explore what causes an increase in blood pressure during exercise (i.e. increased adrenaline levels, or decreased ability of blood vessels to dilate). This study will also test whether or not regular exercise on a bicycle and/or treatment with 6R-BH4 (Kuvan) pills, or histidine and beta-alanine supplementation improves these measures during exercise. 6R-BH4 is currently FDA-approved for use in patients with certain forms of a disease called phenylketonuria, but it is not currently FDA approved for blood pressure or exercise capacity in people with CKD.
Proof of concept, open-label single center study for the donation of HCV positive kidneys to HCV negative patients, with preemptive, interventional treatment to prevent HCV transmission upon transplantation.
Chronic kidney disease is a renal injury and progressive and irreversible loss of kidney function and in its most advanced stage is called chronic renal failure. Although hemodialysis replace some kidney function, patients suffer some alterations characterized by "uremic syndrome" typically expressed by: motor neuropathy and/or autonomic neuropathy, cardiac or musculoskeletal myopathies, peripheral vascular changes, among others. Thus, the functional capacity and ability to exercise presents diminished these patients. The aim of this study is to verify the acute effect of low level laser therapy on the functional capacity of these individuals. The research will be developed in the hemodialysis unit of the Santa Clara hospital of Santa Casa de Misericordia de Porto Alegre and the patients will be evaluated before and immediately after the application of laser therapy protocol. Before the protocol will be evaluated pain in the lower limbs, Borg scale, level of physical activity through the International Physical Activity Questionnaire (IPAQ) and blood collection will be held for later analysis parameters of biochemical oxidative stress and deoxyribonucleic acid (DNA) damage. The laser therapy protocol will be applied in 6 points in quadriceps and 4 points in the gastrocnemius, bilaterally. After application, will be held the 6-minute walk test, effort subjective perception by Borg scale, assessment of pain in the lower limbs with visual analog scale and a new blood sample for further analysis. Patients will be randomized in two groups. The intervention group (IG), which will be held laser therapy and placebo group (PG), where the laser therapy will be placebo mode applied. The application will take place with the Chattanooga device, with the laser diode cluster probe from the same manufacturer consisting of five diodes 850 nanometers (nm) and power output of 200 milliwatts (mW). It is irradiated 6 points in quadriceps and 4 points in gastrocnemius, bilaterally.
The purpose of this study is to determine whether febuxostat and benzbromarone could protect renal function in chinese, and which one could be better.
This is a Phase 1, open label, single-dose, pharmacokinetic study to be conducted in male and female subjects with normal and impaired renal function. The study will be composed of five groups of patients with mild (6 patients), moderate (6 patients), severe (6 patients) renal impairment, end stage renal disease patients on hemodialysis (6 patients) and their respective matched controls in 1:1 ratio (24 healthy subjects with normal renal function). The severity of renal impairment will be assessed based on estimated creatinine clearance (CLCR) by the Cockcroft-Gault equation
Sleep disturbance is a significant issue in people undergoing dialysis. More than 80% of haemodialysis patients complain of difficulty sleeping. Inadequate sleep can cause poor daytime function and increased risk of motor vehicle incidents. One of the common reasons for sleep disturbance in dialysis patients is sleep apnoea. Sleep apnoea involves pauses in breathing that occur during sleep. Each pause can last only a few seconds or minutes. Severe sleep apnoea reduces oxygen supply and increases risk of heart attack and stroke, which are the leading causes of death in dialysis patients. In this project, the investigators will examine how a change of dialysis treatment might improve sleep. This project will first identify patients at risk of sleep disturbance using surveys and a subsequent sleep study. The investigators will then test different dialysis models to see the effect of dialysis treatment on sleep apnoea. The aim is to find a dialysis model that works better for patients with sleep apnoea.
The main objective of this study is to evaluate the feasibility of estimating the prevalence of stage 4 and 5 chronic kidney disease in the Gard department of France from data obtained via laboratory databases. To verifiy if the demand for care thus authenticated by laboratory tests is adapted to nephrology care delivery, as recommended by the French High Authority of Health (HAS), laboratory data will be compared with those of patients seen by nephrologists in the department.
The Investigator hypothesize that a single dose of patiromer will lower serum potassium levels in less than 6hrs. Since a dosage of 30g/day for a period of 4 weeks has been studied in at least two multicenter randomized controlled trials, the Investigator further hypothesize that a single dose of 25.2g of patiromer will be well tolerated in hyperkalemic patients in the Emergency Department setting. The FDA approved dosage of 25.2g is appropriate for this study because the research staff will enroll patients with moderate (K greater than 6 mEq/L) to severe hyperkalemia, and the higher dosage has typically been used in this population for more effective control.
