The prevalence of autonomic nervous system (ANS) dysfunction in patients with end-stage kidney disease (ESKD) is considered to be increased. The uraemic environment, as well as the high incidence of comorbid conditions affecting the ANS function (e.g. diabetes mellitus, autoimmune and degenerative neurological diseases), have been proposed to cause important alterations in ANS function. The vast majority of evidence on the prevalence of ANS dysfunction in ESKD patients is derived from small studies elaborating simple methodology. Noteworthy, with the exception of a study in 27 hemodialysis patients which assessed ANS function before and after dialysis in relation to left ventricular filling pressures, and a 2005 Dutch study in 21 patients whether or not they had hypotension during dialysis, no other study used advanced methods to analyze heart rate or blood pressure variability from beat-to-beat recordings, such as this study. In addition, there is no study so far investigating possible changes in the ANS function per dialysis session. Finally, to the best of our knowledge, this is the first work evaluating possible differences in ANS function in hemodialysis compared with peritoneal dialysis individuals.
This prospective cohort study aim to investigate the ability of multiple types of assessments including 1) the modified Venous Excess Ultrasound (VExUS) assessment, 2) non-invasive estimation of absolute blood volume (ABV), and 3) change in carotid Doppler at the start of IKRT to predict IDHE in acutely ill hospitalized patients. The secondary aim will be to determine whether each modality improves the prediction of IHDE compared to the evaluation of the attending physician and whether they also predict cerebral hypoxia during IKRT measured by near-infrared spectroscopy (NIRS). Finally, detailed hemodynamic data including relative blood volume monitoring, tissue oximetry, and other parameters will be collected continuously during IKRT sessions enabling exploratory analyses aimed at identifying hemodynamic phenotypes related to IDHE during IKRT.
The purpose of this study is to assess the impact of Acute Kidney Injury (AKI) characteristics on long-term renal prognosis in Intensive Care Unit (ICU) patients.
Medications used after transplant to prevent rejection are associated with many side effects. Tacrolimus side effects include kidney dysfunction; tremor, headaches, difficulty sleeping, change in sensation (legs), seizure, or confusion; high blood pressure; anemia, or low blood cell counts; diabetes; abnormal cholesterol and weight gain. The investigators want to use a new, approved, formulation of the standard medication (Envarsus) as they believe it may be associated with reduced side effects. The investigators would like to assess how safe it is to use this medication and how well it works in comparison to currently used formulations. The investigators will study if there are less side effects and will study clinical outcomes (including how well the liver does and if there is need for hospitalizations after transplant). The investigators hope that this information will improve the care provided to and outcomes in patients following liver transplant.
A quasi experimental study that aims to verify whether the incorporation of VExUS in patients with AKI in the Intensive Care Unit (ICU) may prompt tailored interventions to increases the number of days free from Renal Replacement Therapy (RRT) during the first 28 days.
This study aim to investigate the protected effects of short-term use of dapagliflozin (administered within 3 days after procedure) in CKD patients after coronary angiography or percutaneous coronary intervention, as well as observed the incidence of CIN.
Highly prevalent among patients with chronic kidney disease (CKD) and poorly controlled blood pressure (BP), is a modifiable risk factor to abrogate both kidney failure progression and cardiovascular (CV) disease. Spironolactone (SPL), a mineralocorticoid receptor antagonist, is widely used to treat resistant hypertension, however one of the most common side effects is an increase of serum potassium (K). This side effect occurs frequently in those who suffer from CKD. Alternatively, chlorthalidone (CTD) is a thiazide-like diuretic used for treating hypertension and decreases serum K. In this pilot study, our goal is to assess whether the combination of SPL and CTD can improve BP control, while also reducing the risk of hyperkalemia over a period of 12 weeks. We hypothesize that among patients with CKD and poorly controlled hypertension, compared to SPL and placebo, treatment over 12 weeks with CTD will counter the hyperkalemia effect of SPL, and therefore the combination of SPL with CTD will result in a lower BP. This pilot study will be performed at Richard L. Roudebush VA in Indianapolis, Indiana.
Rationale: Perirenal adipose tissue (PRAT) thickness has been associated to worsening renal function and hypertension. The role of PRAT in heart failure with a preserved ejection fraction (HFpEF) has never been established. The hypothesis of this study is that in patients with HFpEF the diameter of PRAT is increased compared with age, sex and BMI matched controls. Objective: The main objective is to determine whether PRAT thickness is increased in patients with HFpEF. Secondary objectives are to determine whether PRAT thickness is correlated to whole kidney perfusion, renal venous flow patterns, markers of glomerular and tubular damage and dysfunction, NT pro-BNP, renin and aldosterone. Lastly, this study aims to determine whether these correlations are similar for men and women with HFpEF. Study design: the proposed study is a single center, cross-sectional observational case-control study, including 30 HFpEF patients and 30 healthy controls. Study population: Adult patients with HFpEF with a body mass index (BMI) of <25.0 or >30.0 and healthy age, sex and BMI-matched controls. Intervention (if applicable): Not applicable. Main study parameters/endpoints: The primary endpoint will be the difference in diameter and volume of perirenal adipose tissue measured on dynamic contrast computed CT (DCE-CT) in patients with HFpEF vs. healthy age, sex and BMI matched controls. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participating subjects will be asked to visit the University Medical Center Groningen (UMCG) twice (once for screening, once for testing visit). During the testing visit they will undergo intravenous contrast abdominal CT, renal sonography, blood drawing and urine collection. Risks associated with these procedure are very limited, rare and include bleeding and infection for venapunction, and contact dermatitis for ultrasound gel. Adverse events for CT include hypersensitivity reactions to contrast agent, which include skin rash, hypotension and bronchospasm.
