35 Clinical Trials for Various Conditions
The REFORM-HF study aims to test a new technology, AquaPass, designed to assist patients experiencing symptoms of fluid overload due to Heart Failure. Patients will wear a lightweight suit that helps remove excess fluids through their sweat. The investigators want to see if the AquaPass system can remove an additional 500mL of fluids during treatment, alongside patients' regular medications like diuretics. Participants will select if to be treated at their home or in the outpatient clinic.
The goal of this clinical trial is to learn about an intensive monitoring plan (transitional care program) in patients with cirrhosis and excessive swelling that are going to be discharged from the hospital. The main question\[s\] it aims to answer are: * How much time and what resources are needed to run such a program * How well do patients follow up with the phone calls, bloodwork, and doctor appointments? * Do the patients enrolled in the program have less need for hospitalization later, less kidney injury, better fluid control, and/or better survival compared to patients that are not in the program? Participants will * Be given a digital scale and a binder with educational material and a log to monitor their weights after discharge from the hospital * Receive a phone call from the study team within 72 hours of discharge and weekly * Be given a follow up appointment with hepatology within 4 weeks of discharge Researchers will compare participants in this program to patients that receive normal care to see if there are differences in need for hospitalization later, kidney injury, fluid control, and/or survival.
This study will evaluate the usefulness of the subcutaneous administration of a new Lasix formulation. 20 patients will be evaluated in the first phase (pilot phase) and depending on the results, an additional 40 patients will be enrolled (Evaluation Phase). Patients with mild to moderate evidence of fluid overload who present to the cardiology service at St Elizabeth's Medical Center, Brighton, Massachusetts (SEMC) will be included in the study. Patients who qualify for thus study will be sent home with the sc2Wear™ Furosemide Infusor therapy for three days. This is a pump that patients place on their abdomen and it then delivers furosemide to the skin. Participants will be visited at home by a visiting nurse who will give them further teaching on the sc2Wear™ Furosemide Infusor. The visiting nurse will also be responsible for obtaining history (symptoms), physical examination (including inspecting the skin for adverse reactions related to the pump), and laboratory draws, supplementation of electrolytes as needed. Patients will be evaluated by the cardiology service of SEMC within 24 hours of the last dose of the sc2Wear™ Furosemide Infusor. If a patient is found to have satisfactorily responded but requires more therapy, an additional 4 days may be prescribed for total of seven consecutive treatments. If additional units are prescribed, patients will be evaluated by the cardiology service of SEMC within 24 hours of the last dose of the sc2Wear™ Furosemide infusion. Also an additionally, up to three-sc2Wear furosemide at home treatments may be used as authorized by the treating physician in case the patient experiences worsening heart failure within 30-days of enrollment (Rescue Treatment). Participants will be seen in clinic for follow up at 30±3 days after the start of the study for a post treatment.
The long-range goal of this proposal is to decrease morbidity and mortality related to pulmonary edema and congestive heart failure (CHF) in post-operative patients. The short-range goal is to determine a mechanistic endpoint when therapy for impending heart failure can be initiated and terminated based on B-type natriuretic peptide (BNP) levels. The investigators propose to utilize changing levels of BNP as a surrogate marker for CHF.
Researchers from the University of Michigan and Northwestern University are studying people's experiences with swelling caused by Nephrotic Syndrome. Interviews with patients (child and adult) and parents of young children will be conducted. The information collected from the interviews will be used to develop a survey to use when testing new medications for Nephrotic Syndrome. Please consider participating in a 1-hour long interview with the Prepare-NS research study to discuss children and adults experiences with swelling.
The REVERSE-HF study is a randomized controlled trial to evaluate clinical outcomes of adjustable ultrafiltration with the Aquadex System as compared to adjustable IV loop diuretics in patients with worsening heart failure (HF) and fluid overload.
The ULTRA-Peds registry will employ a multi-center, single-arm, open-label, observational design to capture baseline, procedural and follow-up data on pediatric patients that have been treated (i.e., retrospective data from treatment at the time of registry approval by the IRB) or are scheduled to be treated (i.e., prospective data for on-label treatment after registry approval by the IRB) with Aquadex therapy according to local standard of care practices and decisions. All prospective data will be from on-label Aquadex treatment of pediatric patients weighing 20 kilograms or more. No data from prospective off-label treatment (i.e., Aquadex treatment with other adjunctive or conjunctive therapies for pediatric patients who may weigh less than 20kg) will be included in the registry. An estimated 10 sites in the United States who have received training in extracorporeal therapy and the Aquadex™ system will enroll a minimum of 500 patients.
* As studied previously, lung congestion is very prevalent however usually asymptomatic in dialysis patients. Fluid overload is associated with hospitalizations, worse cardiovascular outcomes and mortality in PD patients. * The clinical exam is the only tool used currently to monitor volume status of PD patients, and has been found to have poor sensitivity and specificity for lung congestion compared to lung ultrasound. In current practice, patients are seen and examined monthly at their home dialysis units by the nurses. The nephrologist separately examines the patient monthly, possibly days to weeks after the nurse visit, and potentially only quarterly with the use of telehealth visits. * Lung ultrasound is a relatively simple and cheap tool to assess for lung congestion, with little inter-operator variability and good reproducibility. * There are limited studies of lung ultrasound in peritoneal dialysis, and none in the United States. Lung ultrasound may be useful as an objective measure of lung congestion in patients without signs or symptoms of fluid overload. Aims of this study * This study aims to determine the prevalence of subclinical fluid overload in peritoneal dialysis patients. * The investigators aim to determine the added benefit of lung ultrasound to standard clinical practice of fluid management in PD patients. * The investigators aim to assess the association of patient characteristics with lung congestion. * The investigators also aim to assess the agreement between nurse physical exam and lung ultrasound for fluid overload.
The purpose of this study is to examine whether administering metolazone 60 minutes prior to furosemide increases urine output compared with administering metolazone and furosemide concomitantly. Participants will have equal chance of being assigned to each group.
Sodium loading during hemodialysis treatment is common and may contribute to increased interdialytic weight gain and hypertension. Excessive use of isotonic saline (containing 0.9% sodium chloride) is one of the factors that may cause sodium loading. During each hemodialysis session, approximately 400 mL of isotonic saline fluid, representing 1.4 grams of sodium, is used to prime and rinse the extracorporeal circuit, and is often administered to the patient. Switching to a non sodium-containing priming and rinsing fluid could allow for removal of the equivalent amount of sodium. Switching to a non sodium-containing solution for the priming and rinsing of the extracorporeal circuit can contribute to increased sodium removal during the dialysis treatment and allow for reduced interdialytic weight gain, reduced thirst, and improved blood pressure control.
The primary objective of this study is to learn whether a morning dose of extended-release torsemide enhances renal sodium excretion after lunch (4-8 hours after dosing) compared to immediate-release torsemide. This is a randomized, double-blind, crossover study in patients with heart failure who are on a stable dose of a loop diuretic. During the study period, participants' current loop diuretics will be replaced with an equivalent dose of either immediate-release or extended-release torsemide. Following a one-week stabilization period on the assigned torsemide formulation, patients will report to the clinical site for an assessment visit. On the study day, patients will take a single dose of the same torsemide formulation they have been on for the past week, administered after breakfast. Urine samples be collected are: * 0-4 hours post-dosing (pre-lunch period) * 4-8 hours post-dosing (post-lunch period) * 8-24 hours post-dosing (24 hours period) The primary endpoint will be urinary sodium excretion (4-8 hours after dosing). This will be compared between the extended-release arm and the immediate-release arm to assess the efficacy of prolonged diuretic action. In addition, urinary potassium and creatinine excretion and creatinine clearance will be measured in all urine samples as the safety endpoints.
There is a growing focus on short- and long-term kidney health in neonates, including those with acute kidney injury (AKI). AKI occurs commonly in the Neonatal Intensive Care Unit (NICU) and is associated with adverse outcomes. In addition to poor outcomes during the hospitalization, infants discharged from the NICU may have an increased burden of kidney disease during childhood. Studies of long-term kidney function in children born prematurely show a fourfold increase in chronic kidney disease (CKD) by adolescence and into adulthood. Despite the landmark findings of the Assessment of Worldwide Acute Kidney Injury Epidemiology in Neonates (AWAKEN) study, the limitations of this study are notable. First, the AWAKEN study enrolled infants admitted in 2014, making the data now over 10 years old. Much has changed in neonatal practice (e.g. increased AKI awareness, treatment strategies). Secondly, the findings of the AWAKEN study were geographically limited. While the AWAKEN study was multi-national and multi-center, it represented only 24 centers (22 from North America, 1 from India and 1 from Australia). Finally, information collected from AWAKEN ended at hospital discharge. The investigators seek to leverage the strength of the Neonatal Kidney Collaborative along with other organizations and collaboratives interested in neonatal kidney health to address these gaps. Therefore, the investigators are conducting a second, modified iteration of this study entitled "AWAKEN 2.0". AWAKEN 2.0 will be a multi-center multi-national retrospective analysis utilizing similar methodology to the AWAKEN study.
A retrospective multicenter, observational design intended to capture data on pediatrics (weighing between 8 - 20 kg) who underwent continuous renal replacement therapy (CRRT) using the HF20 set. Data will be compared with a similar population (weighting 8-20 kg) from the ppCRRT registry who received CRRT with Prismaflex M60 sets.
Fluid administration is a commonly performed in the ICU for critically ill patients. However, it can lead to complications such as fluid overload, pulmonary edema, and increased mortality in some patients. Therefore, identifying patients who are likely to respond to fluid therapy is crucial for optimizing their management. Several methods have been used to assess fluid responsiveness, such as passive leg raising, stroke volume variation, and cardiac output monitoring. However, these methods have limitations and may not be feasible in all patients. In this study, the investigators aim to evaluate the use of velocity time integral (VTI) and Trendelenburg positioning in predicting fluid responsiveness in ICU patients.
This study aims to compare the pharmacokinetics and pharmacodynamics of intravenous (IV) and subcutaneous (SC) furosemide. The test formulation in this study is furosemide injection, 80 mg/1 mL, buffered to a neutral pH for SC administration via an autoinjector. A commercial formulation of furosemide injection, USP, solution 10 mg/mL administered as a 40 mg IV injection over 2 minutes followed by a second dose of 40 mg, 2 hours later, will serve as the reference drug. The objectives of this study are: * To estimate the bioavailability and describe the pharmacokinetics and pharmacodynamics of furosemide administered as SC injection via autoinjector compared with equivalent dose of furosemide administered as two 40 mg IV injections, two hours apart. * To describe the safety and tolerability of furosemide administered as SC injection via an autoinjector.
Critically ill patients with acute kidney injury and fluid overload who are frequently treated by fluid removal during dialysis are at an increased risk of complications and death. Both slower and faster rates of fluid removal may cause injury to the vital organs. This proposed clinical trial will examine the feasibility of restrictive compared with a liberal rate of fluid removal in order to develop effective treatments for fluid overload and to improve the health of critically ill patients.
The post market surveillance study will employ a prospective, multi-center, single-arm, observational design to capture data on children who undergo CRRT using the Carpediem™ system. Participating clinicians will manage subjects in accordance to their local standard of care practices and decisions on initiating, modifying or discontinuing CRRT are up to the local investigative team's prescription. A minimum of 10 centers in the United States, that have been trained on the use of the Carpediem™ system, will be invited to participate in the study. After obtaining institutional review board approval and written informed consent from a parent or legally authorized representative (LAR), data from all subjects treated with the Carpediem™ system will be included in the study. A minimum of 35 subjects will be enrolled and sites may be asked to screen and enroll patients for the study for up to 36 months. Status of subjects discharged from hospital will be collected at 30- and-90 days following hospital discharge by phone interviews in accordance to local standard of care practices, review of in-hospital records or in-clinic visit, as available.
Pregnancy is associated with a myriad of physiologic changes, including expansion of blood volume, decrease in oncotic pressure, and increased cardiac output. The obstetric population is associated with intrapartum hemorrhage. Accordingly, it is important to have an accurate method to assess fluid status in intrapartum patients. The use of standard volume assessment tools including arterial lines and central venous catheters is limited given the brevity of obstetric procedures and the morbidity of these techniques on the awake patients, and the costs. Non-invasive methods to assess volume status (carotid dopplers, direct measurement of blood loss, bio-impedance devices) are imperfect. Echocardiography is an attractive tool to measure fluid status in experienced operators such as anesthesiologists. IVC diameter and variation of aortic velocity time integral are two measures that can be obtained via echocardiography and been studied in spontaneously breathing patients. The purpose of this study is to determine whether these measurements can be used in the assessment of volume status in the laboring patient.
The objective of this feasibility study is to characterize the performance of the Aquadex FlexFlow® System with the hematocrit (HCT) feature in conjunction with Daxor's blood volume analyzer (BVA-100). The study will monitor blood volume changes during ultrafiltration (UF) therapy as a potential means to guide the removal of fluid in subjects hospitalized with acute decompensated heart failure (ADHF).
A common complication of the progression of cirrhosis is fluid retention (ascites, edema, or pleural effusion). Loop diuretics are the treatment of choice for fluid retention in cirrhotic patients; however, many of these patients demonstrate diuretic resistance, requiring higher doses of the diuretics to achieve adequate diuresis. The cause of this diuretic resistance is hypothesized to be secondary to hypoalbuminemia which has led some providers to give human albumin in combination with loop diuretics to increase intravascular volume and facilitate diuresis. However, this practice remains controversial because minimal data exists to support its efficacy. The purpose of this study is to compare the efficacy of diuretics alone versus diuretics in combination with albumin in cirrhotic patients presenting with fluid retention.
Babies can be born with heart problems and sometimes need a heart surgery to fix the heart problem. Heart surgery can cause swelling from the build-up of extra fluid. Swelling can make it harder for babies to breath and has to be treated with medicine called diuretics. Swelling is hard to measure in babies, so it can be hard to know how much diuretic they need to treat the swelling. The investigators are looking for a better way to measure swelling in babies who have had heart surgery. Ultrasound uses sound waves to take pictures of the inside of the body. Ultrasound is used to take pictures of babies before they are born and to take pictures of their heart after they are born. New ultrasound software has been made from a company called MuscleSound that can quickly measure the amount of swelling in adults, usually in less than 2 minutes. This software has not yet been used to measure swelling in kids. This study plans to learn more about swelling in babies and will try to measure swelling in babies before and after heart surgery with the new ultrasound software. The study will also make the same measurements in babies who do not have heart disease to compare to babies having heart surgery.
Fluid overload is associated with adverse outcomes in patients with severe acute kidney injury. It remains unclear if fluid overload is merely a marker of disease severity or if organ congestion is a mediator of complications. Point-of-care ultrasound could be a modality used to assess organ congestion and its clinical implications. The objective of this study is to determine whether ultrasound markers of organ congestion are associated with major adverse kidney events in critically ill patients with severe acute kidney injury.
This is a randomized clinical trial in which maintenance hemodialysis patients will be provided with salt restricted 'dialysis friendly' meals and compared to a control arm receiving usual care.
This is a pilot randomized clinical trial in which patients treated with 3X per weekly conventional hemodialysis will be treated to a dialysate sodium 135 mEq/L vs. 138 mEq/L and followed for safety and tolerability, effects on BP and volume.
Accurate assessment of fluid responsiveness (FRes) is central to guiding fluid management in septic and critically ill patients. As evidence accumulates that both inadequate and excessive fluid resuscitation are associated with increased morbidity and mortality, it is simultaneously becoming increasingly clear that current widely used methods to predict FRes are of questionable accuracy. The optimal technique to predict FRes would be a non-invasive point-of-care test with not only a high degree of accuracy, but also one which requires minimal training to perform correctly and may be easily performed repeatedly for serial evaluation of FRes during the ongoing management of the critically ill patient. To date, three major ultrasonographic modalities have emerged as viable candidates for the bedside assessment of FRes: 1) measurement of dynamic changes in inferior vena caval diameter (IVC-CI), 2) measurement of dynamic changes in peripheral arterial waveform derived variables (PA Doppler), and 3) echocardiographic measurement of dynamic changes in left ventricular outflow tract waveform derived variables (LVOT Doppler). In this study, the investigators will perform the first direct comparison of techniques representing all three of the above modalities in the prediction of FRes against a non-invasive bioreactance cardiac output monitor (the Cheetah NICOM™), which has been extensively validated against gold-standard invasive methods of cardiac output measurement. The investigators will compare the accuracy of these modalities in both spontaneously breathing and mechanically ventilated patients using passive leg raise testing (PLR) as a surrogate for volume challenge. In addition, the investigators will also elicit information from the treating physician(s) on their clinical assessment of FRes. The investigators will recruit adult patients in the ED and ICU with sepsis, who have received an initial bolus of 20-30 cc/kg of IV fluid, and can tolerate the PLR and US procedures. Prior to US and NICOM measurement, investigators will ask the attending physician managing the patient regarding their assessment of the their fluid status. Then, separate investigators will perform US and NICOM measurements independently to ensure blinding. NICOM data, which has been well validated in septic patients, will be shared with the attending physician. They will then be asked if this new data will change management.
Acute Kidney Injury (AKI) is a common clinical problem defined by an abrupt (\< 48 hour) increase in serum creatinine (SCr) resulting from an injury or insult that causes a functional or structural change in the kidney. Despite significant advancements in the care of the critically ill child, mortality rates observed in critically ill children who develop AKI have not improved. The investigators have shown even "small" increases in SCr, which is the standard kidney function marker, are associated with increased child mortality, even when outcome was controlled for significant patient co-morbidity. Furthermore, the investigators have also shown that the amount of fluid accumulation observed in critically ill children with AKI is independently associated with mortality suggesting that earlier dialysis may improve survival. However, the investigators also do not want to dialyze patients who don't ultimately need dialysis, as it is an invasive procedure. The data cited above highlight the need not only to detect AKI early, but also predict it severity in order to optimize clinical decision making with respect to fluid administration and dialysis initiation. While substantial research has been expended to validate NGAL as an early marker of AKI, it has not been studied in the context of clinical decision support to guide a therapeutic intervention. The investigators hypothesize that NGAL levels can be used to determine predict which critically ill children will develop severe and prolonged AKI with substantial volume overload, thereby providing the clinician with a diagnostic tool to guide CRRT initiation.
The purpose of this study is to evaluate the safety, tolerability, drug levels, and drug effects of BMS-986308 compared to placebo in healthy participants.
The specific aim of this study is to gather data on fluid balance, intravenous medication administration, electrolyte balance, and diuretic and dialysis use in patients with acute respiratory failure who might benefit from a strategy designed to limit fluid administration.
Introduction: Based on single-center data, approximately 1 of every 3 newborns admitted to tertiary level neonatal intensive care units (NICU) develops acute kidney injury (AKI), and those with AKI have significantly worse outcomes. To stimulate discussion among researchers, the NIH NIDDK sponsored a workshop on neonatal AKI in April 2013. At that workshop, the group recognized the need to improve collaborations between neonatologists and nephrologists within and across centers. The investigators have created a multi-institutional, multi-disciplinary group, Neonatal Kidney Collaborative (NKC), in order to address the following critical needs identified at the workshop: AWAKEN is the inaugural study of this new collaboration. 1. Development of a standardized evidence-based definition of neonatal AKI 2. Evaluation of risk factors that predispose neonatal to AKI 3. Investigation into how fluid provision/ balance impacts biochemical and clinical outcomes
The present study is designed to confirm and extend the observation from previous studies that lixivaptan therapy corrects hyponatremia, in euvolemic subject, including subjects with SIADH.
