Filter by:Renal resistive index (RRI) is calculated from ultrasonographic Doppler measurements of flow velocities in intraparenchymal renal arteries. Normal values are around 0.60, and 0.70 is considered the upper normal threshold in adults. Both preoperative and postoperative elevation of RRI has shown promise in early detection of AKI after cardiac surgery. Further, elevated RRI before coronary angiography is associated with an increased risk of cardiovascular complications up to 1 year after the procedure. The role of preoperative RRI in predicting long-term renal and cardiovascular complications after elective surgery is however not known. The aim of this study is to assess the role of preoperative RRI to predict the risk of persistent renal dysfunction as well as renal- and cardiovascular complications up to 5 years after surgery.
Chronic kidney disease (CKD), especially end-stage kidney disease (ESKD), is associated with increased risk for cardiovascular events and all-cause mortality. Exercise intolerance as well as reduced cardiovascular reserve are extremely common in patients with CKD. Cardiopulmonary exercise testing (CPET) is a non-invasive, dynamic technique that provides an integrative evaluation of cardiovascular, pulmonary, neuropsychological and metabolic function during maximal or submaximal exercise, allowing the evaluation of functional reserves of these systems. CPET is currently considered to be the gold-standard for identifying exercise limitation and differentiating its causes. It has been widely used in several medical fields for risk stratification, clinical evaluation and other applications. However, the use of CPET in assessment of exercise intolerance in everyday nephrology practice is limited. Hence, this is the first study possible differences in CPET's parameters during long and short interdialytic intervals in hemodialysis patients.
This study consists of two phases. The purpose of phase 1 is to identify incidence and patterns of erythropoiesis-stimulating agent (ESA) hyporesponsiveness and its associated factors in ESA treated patients. The purpose of phase 2 to identify outcomes associated with ESA hyporesponsiveness. Key aspects of the phase 2 study design will entirely depend on the results from phase 1.
Researchers are looking for a better way to treat people who have chronic kidney disease (CKD). The kidneys filter extra water and waste out of the blood and make urine. CKD is a long-term, progressive, decrease in the kidneys' ability to filter the blood properly. High blood pressure makes it more likely that the CKD gets worse. The study treatment BAY3283142 is under development for treating CKD. It activates a protein called soluble guanylate cyclase (sGC) that generates cGMP - a molecule that relaxes blood vessels and is thought to have beneficial effects in CKD. The participants do not benefit from this study. However, the study will provide information on how to use BAY3283142 in subsequent studies in people with CKD. In previous studies, BAY3283142 was studied in participants with normal kidney function. As kidneys play a role in removal of drugs from the body, the degree of kidney function could influence the amount of BAY3283142 in the blood. Higher amounts may occur in people with reduced kidney function. Therefore, the main purpose of this study is to learn how the study treatment BAY3283142 moves into, through, and out of the body in participants with mild to severe reduction of kidney function compared to matched participants with normal kidney function. To answer this, the researchers will compare: - the (average) total level of BAY3283142 in the blood (also called AUC). - the (average) highest level of BAY3283142 in the blood (also called cmax) between the different groups. Participants will be in one of four groups based on how much their kidney function is reduced (mild, moderate, severe, end stage kidney disease) or in the control group. All participants will take a single dose of BAY3283142 as tablet by mouth. Each participant will be in the study for approximately 4 weeks including an in-house stay of 6 days (with 5 overnight stays). In addition, a screening visit to the study site before the in-house stay is planned. During the study, the study team will: - check vital signs - do physical examinations - take blood and urine samples - examine heart health using an electrocardiogram (ECG) - ask the participants questions about how they are feeling and what adverse events they are having An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments.
Researchers are looking for a better way to treat people who have chronic kidney disease (CKD), a progressive decrease in the kidneys' ability to work properly. In people with CKD, the kidneys do not remove wastes and extra fluid from the blood as well as they should. High blood pressure makes it more likely that the CKD gets worse. The study treatment BAY3283142 is under development for treating CKD. It activates a protein called soluble guanylate cyclase (sGC) that generates cGMP - a molecule that relaxes blood vessels and is thought to have beneficial effects in CKD. The participants do not benefit from this study. However, the study will provide information on how to use BAY3283142 in subsequent studies in people with CKD. As many people with CKD do also suffer from high blood pressure, this study is done in people with mild to moderate high blood pressure to safeguard the use of BAY3283142 in people with CKD in later studies. The main purpose of this study is to learn how safe different single and multiple doses of the study treatment BAY3283142 are compared to placebo in male and female participants (after menopause) with mild to moderate high blood pressure. A placebo is a treatment that looks like a medicine but does not have any medicine in it. To answer this, the researchers will compare the number of participants who have medical problems after taking BAY3283142 to those treated with placebo. Doctors keep track of all medical problems that happen in studies, even if they do not think they might be related to the study treatments. Dependent on the treatment group, the participants will either take BAY3283142 or placebo as tablet once or twice a day. Patients will take one dose for 6 days and will then be switched to a higher dose for additional 6 days. In summary, three different dose combinations consisting of two different doses each will be tested. Participants will be in the study for up to 7 weeks, including 12 treatment days (6 per dose step). They will stay in-house for 17 days starting two days before intake of the study treatment. In addition, one visit before and one visit after the in-house phase to the study site is planned. During the study, the study team will: - Check vital signs - Take blood and urine samples - Examine the participants' heart health using electrocardiogram (ECG)
The purpose of this study is to access the efficacy and safety of MC2-25 cream and MC2-25 vehicle for treatment of chronic kidney disease associated pruritus (CKD)-aP).
The goal of this clinical trial was to compare transdermal glomerular filtration rate (tGFR) to plasma-derived indexed (to body surface area; BSA) GFR (nGFR) using MB-102 (relmapirazin) as the fluorescent compound. Adults with kidney function ranging from normal to Stage 4 chronic kidney disease (CKD) and participants spanning the entire range of human skin colors as defined by the Fitzpatrick Skin Scale (FSS) were included in the study. The main questions that the study aimed to answer were: - To establish that the MB-102 transdermal fluorescence measured GFR using the MediBeacon Transdermal GFR Measurement System is comparable to the measured MB-102 plasma GFR - To evaluate the safety and tolerability of a single dose of MB-102 in study participants - To evaluate the safety and effectiveness of the MediBeacon Transdermal GFR Measurement System (TGFR) for the non-invasive transdermal fluorescence detection of MB-102 in participants Participants had a transdermal sensor placed on their upper chest, and the TGFR collected background fluorescence. Participants then received a single dose of MB-102. Blood samples were collected and fluorescent measurements were taken over a 12- to 24-hour period. Following completion of the treatment period, participants returned to the study center approximately 1 week later for a safety follow-up visit. Researchers compared the results to see if the transdermal GFR measurements were comparable to the measured plasma GFR in those with and without normal kidney function and different skin coloration.
This is an observational study in which patients with chronic kidney diseases (CKD), type 2 diabetes (T2D) or heart failure (HF) who are current or past users of sMRA therapies are studied. sMRA stands for steroidal mineralocorticoid receptor antagonists. CKD is a long-term, progressive decrease in the kidneys' ability to work properly. Type 2 diabetes is a condition in which the body does not make enough of a hormone called insulin or does not use insulin well resulting in high blood sugar levels. HF is a condition in which the heart does not pump blood as well as it should. The renin-angiotensin-aldosterone system (RAAS) is a hormone system that works with the kidneys to control blood pressure and the balance of fluid and electrolytes (like salt) in the blood. The RAAS has been a treatment target of heart and kidney diseases for decades. One of these classes of medications is called mineralocorticoid receptor (MR) antagonists (MRAs). MRAs work to directly block the action of a hormone called aldosterone. Aldosterone is produced naturally by the adrenal glands, and it can increase the blood volume and blood pressure. Using MRAs therapies can help prevent strokes, heart attacks and kidney problems. Spironolactone was the first available MRA in the US with its approval in 1960. Eplerenone is another MRA which has been available since 2002. Both spironolactone and eplerenone are known as steroidal MRA (sMRA) due to their chemical structures. The main purpose of this study is to collect more data on the characteristics of patients who are taking sMRA currently and those who have discontinued sMRA therapy in the past 12 months. To do this, patients who have received sMRA in the most recent 12 months will be invited to participate in the study and asked to complete surveys if they agree to join the study. Patients will be found from administrative claims in a database called HealthCore Integrated Research Database (HIRD). And the other purposes of the study are to learn more about: - the indications for sMRA therapy - the frequency and symptoms of reported side effects of sMRA treatment - the treatment satisfaction and effectiveness as well as potential reasons for treatment continuation/discontinuation of sMRA therapies Besides this data collection, no further tests or examinations are planned in this study. The participants will receive their treatments as prescribed by their doctors during routine practice according to the approved product information. Researchers will look at the health information from adult men and women in the US only if applicable who are current/past users of sMRA therapies with diagnosis of CKD or T2D or HF, consent to participate in the study.
This cross-sectional study was conducted, including those subjects tested for 1,25(OH)2D during Jan 2015-Dec 2021. Estimated glomerular filtration rate (eGFR) was calculated and subjects were classified into chronic kidney disease (CKD) stages. Associations between biochemical marker, calcium, phosphorus, magnesium, alkaline phosphatase, 1,25(OH)2D and CKD stages was determined.
