Filter by:Laparoscopic and minimally-invasive robotic access has transformed the delivery of urological surgery. While associated with numerous desirable outcomes including shorter post-operative stay and faster return to preoperative function, these techniques have also been associated with morbidity such as reduced renal blood flow and post-operative renal dysfunction. The mechanisms leading to these renal effects complex are multifactorial, and have not been fully elucidated. However they are likely to include direct effects from raised intra-abdominal pressure, and indirect effects secondary to carbon dioxide absorption, neuroendocrine factors and tissue damage from oxidative stress. It is well documented that pneumoperitoneum places profound stress on the cardiovascular, respiratory and gastrointestinal systems; it also places strain on the renal system. During robotic surgery, continuous pneumoperitoneum and continuous rising of intra-abdominal pressure causes transient oliguria. Moreover, kidney function, estimated by the GFR, deteriorates during elevated intra abdominal pressure (IAP), and most of the studies identified decrease in renal blood flow (RBF) and renal cortical perfusion. Studies conducted to assess the contribution of the nitric oxide (NO) system to the renal hemodynamic/function alterations during pneumoperitoneum, concluded that these adverse effects are probably related to interference with the NO system, and could be partially ameliorated by pretreatment with nitroglycerine. Mannitol is an osmotic diuretic and a renal vasodilator that promotes tubular flow, prevents intratubular cast formation, decreases postischemic cellular swelling, and might serve as a free radical scavenger. Mannitol has traditionally been administered before renal surgeries to minimize perioperative renal dysfunction according to preclinical animal studies and clinical experience with renal transplantation. However, high-level clinical data in support of this belief are not available. The aim of this study is to characterize the effects of increased intra-abdominal pressure on renal perfusion and function in cases undergoing robotic lower tract urologic surgeries, and to assess the contribution of either mannitol or nitroglycerin infusion to the renal hemodynamic/function alterations during pneumoperitoneum.
Metabolic syndrome is a collection of conditions that affect at least three of the following five criteria: abdominal obesity, high blood pressure, high fasting glucose levels, high triglyceride levels, and low levels of high-density lipoprotein (HDL) cholesterol. Chronic kidney disease (CKD) is a common complication of metabolic syndrome, with an estimated prevalence of 13-40%. Early diagnosis of progressive conditions before the onset of reduced glomerular filtration rate (GFR) or albuminuria may be of clinical benefit but is not possible at present. Furthermore, the diagnosis and quantification of CKD in the context of metabolic syndrome is challenging due to the lack of reliable diagnostic biomarkers, and the current methods may not accurately reflect kidney function in patients with metabolic syndrome. Magnetic resonance imaging (MRI) has been sparsely explored as a potential tool to assess renal perfusion, oxygenation, and fibrosis. Multiparametric MRI (mpMRI) combines several different imaging techniques to provide a more comprehensive evaluation of tissue structure and function. These techniques hold promise for non-invasive assessment of kidney function, but their clinical utility is still largely experimental. Therefore, we aim to conduct an exploratory study to investigate the reliability, reproducibility as well as the validity of parameters for kidney function of multiparametric MRI as well as compare these parameters in between healthy patients and patients with metabolic syndrome.
This study is open to adults aged between 18 and 80 years of age with a body mass index (BMI) of 20 to 40 kg/m2. People with or without kidney problems can take part in the study. The purpose of this study is to find out how much of a medicine called BI 456906 gets into the blood of people with and without kidney problems. BI 456906 is being developed to treat people with obesity and liver problems. People living with these conditions often also have kidney problems. Therefore, it is important to find out whether kidney problems influence the amount of BI 456906 that gets into the blood. Study participants receive a single dose of BI 456906 as an injection under the skin. Participants are divided into 4 groups based on how well their kidneys work: 1 group without kidney problems, and 3 groups with mild, moderate, and severe kidney problems. Each participant without kidney problems is matched with participants from the other groups based on factors such as age, gender, race, and body mass index (BMI) to ensure accurate comparisons. Participants are in the study for about 2 months. They stay for 5 days and 4 nights at the study site and visit their doctors about 7 times. During these visits, the doctors collect information about participants' health. To assess the study endpoints, the doctors regularly take blood samples from the participants. The participants also answer questions about their well-being. The doctors regularly check participants' health and take note of any unwanted effects.
The purpose of this study is to understand how the loss of kidney function affects study medicine (PF-07923568) in the body. People with some level of loss of kidney function may process PF-07923568 differently from healthy people. PF-07923568 is developed as a possible treatment for respiratory syncytial virus (RSV) infection. RSV is a common virus that affects the lungs and usually causes mild, cold-like symptoms. RSV can cause severe lung infections in infants, elderly, and adults with other serious medical conditions. This study is seeking participants who: - Have less than 25% difference in kidney function between 2 screening visits. - Meet the eGFR criteria for being assigned to groups. eGFR tells how well the kidney is filtering. - Are not on hemodialysis. Hemodialysis is a type of treatment that helps the body remove extra fluid and waste products from the blood when the kidneys are not able to. Participants will take the study medicine as capsules by mouth once at the study clinic. The participants will stay at the study clinic for about 5 days. During that time, the study team will monitor the participants. The study team will take some blood samples to test the level of PF-07923568. This will help us understand if some level of loss of kidney function will have an effect on the study medicine PF-07923568.
This is an open-label, single-dose study to evaluate the pharmacokinetics and safety of HSK21542 in subjects with mild, moderate and severe renal impairment compared to the matched control subjects with normal renal function.
The primary purpose of this study is to assess the effect of renal impairment on the pharmacokinetics (PK) of emraclidine following administration of a single oral dose in participants with mild, moderate, and severe renal impairment relative to matched participants with normal renal function.
Renal Impairment study of GBT021601.
The purpose of this study is to evaluate the pharmacokinetics and safety of a single dose of Inaxaplin (IXP) in participants with severe renal impairment and healthy participants with normal renal function.
The rationale of this study is to evaluate the impact of renal function on the PK, safety, and tolerability of VIR-2218 in participants with normal renal function and participants with varying degrees of renal dysfunction who are otherwise medically stable
This Study will evaluate the effects of renal function on pharmacokinetics and safety of DA-8010
