Plant Versus Animal Dietary Protein and the Effect on Proteinuria
Kidney InsufficiencyDiabetes Mellitus10 moreThe purpose of this study is to investigate if a diet high in plant protein improves kidney function in patients with kidney insufficiency and diabetes and/or hypertension and/or glomerulonephritis. The study is a non-blinded, randomized, controlled, cross-over-design with two intervention periods of each 14 days. Between the two interventions periods there is a washout period of 14 days. The participants are randomized to start with an individualized diet plan containing either high amounts of animal protein or high amounts of plant protein.
Early Haemadsorption in Major Burns
BurnsMultiple Organ Failure5 moreMajor deep burns (>20% body surface, involving deep skin layers) and associated severe inflammatory reaction and their complication are one of the biggest challenge of intensive care. Haemoadsorption therapy, including the CytoSorb treatment is a promising novel therapeutic approach, but only case-studies are available in the literature yet. Based on data from septic shock patient treatment the investigators hypothesize that CytoSorb is beneficial in early treatment of burns. The investigators aim to conduct a randomised-controlled study to assess the clinical effectiveness (based on score systems including MODS, SOFA, APACHE II, KDIGO, ABSI), 7 and 28 days survival, intensive care length of stay, length of mechanical ventilation, resuscitation fluid need and ino/vasopressor drug doses and the presence and severity of organ dysfunctions, particularly renal dysfunction. The investigatora plan to conduct basic research to elucidate the pathophysiological background of clinical effect, including the measurement of inflammatory and anti-inflammatory cytokines, presence and severity of oxidative stress (lipid peroxidation, protein oxidation, reduced/oxidised glutathion levels) and organ dysfunction markers (kidney injury molecule -1, neutrophil gelatinase-associated lipocalin, cystatin-C, uromodulin).

Contrast-induced NephropathyRandomized parallel group study comparing the renal safety of Captisol-Enabled™ Iohexol (CE-Iohexol) Injection and Omnipaque™ (Iohexol) Injection in patients with impaired renal function undergoing coronary angiography.
Metformin Versus Vildagliptin in Reducing Risk of Metabolic Syndrome Complications Progression
Metabolic SyndromeDiabete Type 21 moreSeveral crosssectional and prospective studies have shown that metabolic syndrome and its related components are associated with both prevalent and incident CKD . Although the mechanisms for these cardiovascular benefits of Metformin and vildagliptin remain unclear, they extend well beyond glycemic lowering, and therefore are probably best considered diverse "cardiometabolic" pharmaceuticals rather than simply type 2 diabetes drugs. Metformin and vildagliptin have known vasculoprotective actions, but the value of these drugs on drug-naïve diabetic patients during 24 week use warrants investigation. The investigator's purpose was to observe their effects on weight control, Cardiometabolic Risk Factors, Metabolic Syndrome risk, and diabetic nephrooathy Progression.

In this regard, protein intake impact will be measured on muscle mass, physical performance and renal function as main outcome. Rehospitalization, quality of life, depression an inflammatory status are second endpoints.
Efficacy Transverse Abdominal Plane (TAP) Block Renal Transplant Surgery
Renal InsufficiencyChronic4 moreThe objective of this study is to evaluate the efficacy and safety of transverse abdominal plane block in patients undergoing renal transplant surgery.Adult renal transplant recipients will be prospectively randomized to receive a standard general anesthetic technique supplemented with ropivacaine 0.375% 20 mL TAP block or sham block with 20 mL 0.9% saline. Both groups will receive patient-controlled morphine analgesia. Patient assessment will occur in the postanesthetic care unit and at 1, 2, 4, 6, 12, and 24 hours. The primary outcome is total morphine consumption in the first 24 hours after renal transplantation. Other outcomes asses include pain scores, presence of nausea or vomiting, excessive sedation, and respiratory depression.
Low-level Laser Therapy in Chronic Kidney Disease
Kidney FailureChronicChronic 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.

Comparing the Effects of Spironolactone With Chlortalidone on LV Mass in Patients With CKD
Renal InsufficiencyChronic1 moreIn stage 3 chronic kidney disease (CKD) the risk of death due to cardiovascular causes is high and greatly exceeds the risk of progression to end stage renal failure. This high cardiovascular risk is predominantly due to sudden cardiac death and heart failure, manifestations of left ventricular hypertrophy and fibrosis. Aldosterone appears to play an important role in the causation of this myocardial disease both by direct inflammatory and fibrotic myocardial effects and via increased arterial stiffness due to hypertrophy, inflammation, and fibrosis within the media of large arteries. Levels of aldosterone are high in CKD despite sodium overload and treatment with angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) drugs due to the twin phenomena of aldosterone escape and breakthrough. In a previous British Heart Foundation funded study, Birmingham investigators showed that the addition of the mineralocorticoid receptor blocker (MRB) spironolactone to background therapy with ACE inhibitors or ARBs caused reductions in the prognostically important parameters of arterial stiffness and LV mass. Because spironolactone therapy was also associated with significant falls in arterial pressure it remains possible that these effects were mediated simply by blood pressure reduction. In this multi-centre, randomised controlled study, the effects of treatment with spironolactone on LV mass and arterial stiffness in patients with stage 3 CKD on established ACE or ARB therapy will be compared to those of chlortalidone, a control anti-hypertensive agent. Early stage chronic kidney disease is highly prevalent and new, cost effective treatment strategies are required to reduce cardiovascular risk. This study is designed to provide the rationale for a larger study of morbidity and mortality with MRB therapy in early stage CKD.
