Methadone Pharmacokinetics in End-stage Renal Disease

Chronic Kidney DiseasesPost Operative Pain2 more

The goal of this observational study is to describe the influence of renal function on the pharmacokinetics of methadone used through an intravenous patient-controlled analgesia (IV-PCA) pump for the management of acute postoperative pain. The main question it aims to answer is: • Is the pharmacokinetic of methadone used in an IV-PCA pump impaired in patients with chronic kidney disease? After surgery the participants will use an IV-PCA of methadone and blood samples will be withdrawn to measure the plasmatic levels of it.

Evaluation of Some Puberty-related Hormones Among Children and Adolescents With Chronic Kidney Diseases...

Evaluation of Some Puberty-related Hormones Among Children and Adolescents With Chronic Kidney Diseases

Puberty is the process of transition from childhood into adolescence, signaling the readiness of the human body for reproduction. The Hypothalamic-Pituitary Gonadotropin axis plays the primary role in initiating the puberty, where the hypothalamus secrets gonadotropin releasing hormone (GnRH) in a pulsatile manner, which in turn stimulates the release of luteinizing hormone (LH), and follicle stimulating hormone (FSH) from the anterior lobe of the pituitary gland, and in a final step these hormones stimulate the gonads to release their sex hormones (Testosterone and Estradiol) . Chronic illnesses can affect this physiological process resulting in delayed puberty . Delayed puberty is defined as the lack of pubertal signs until the age of 13 years in girls, and the age of 14 years in boys. Delayed puberty is classified into two categories according to their cause; central gonadotropin deficiency (hypogonadotropic hypogonadism) and this type comprises delayed puberty due to chronic illness, while the second category of delayed puberty is due to gonadal disorders (hypergonadotropic hypogonadism). Delayed puberty is common among pediatric patients with chronic kidney disease (CKD) - where glomerular filtration rate (GFR) is less than 60 ml/min per 1.73 m2. Previous studies suggested that, the cyclic pattern of GnRH release is lost in patients with CKD resulting in impairment of gonadotropins secretion from the anterior pituitary gland. Multiple hormonal factors had been proposed to be responsible for the pubertal delay in patients with CKD, the most prominent of which is the increasing levels of prolactin, LH and GnRH (4). Prolactin normally inhibits the release of GnRH from hypothalamus thus inhibiting the initiation of puberty and it was found to increase in patients with CKD secondary to increased production, slightly decreased clearance and decreased responsiveness to the hypothalamic inhibition of prolactin secretion. Furthermore, recent studies reported that the Kisspeptin protein play an important role in the regulation and control of normal puberty, As it was found that the Kisspeptin neurons (the rostral periventricular region of the third ventricle (RP3V) and arcuate nucleus (ARC), are found in close association with the GnRH releasing neurons in the hypothalamus suggesting that these neurons might play a crucial role in activating and restoring the pulsatile release of GnRH, It was also found that inactivating mutations of the gene encoding for kisspeptin were associated with hypogonadotropic hypogonadism.

Study to Evaluate the Efficacy, Safety and Pharmacokinetics of Three-times Weekly Dosing of GSK1278863...

Anaemia

GSK1278863 is an orally available, hypoxia-inducible factor - prolyl hydroxylase inhibitor, currently being investigated as a treatment for anemia associated with chronic kidney disease. GSK1278863 has been given as a once daily regimen in clinical studies to date. However, physicians in countries that use a three-times weekly hemodialysis schedule prefer to give the anemia medicine at the same time as the dialysis session. This study will test how well GSK1278863 can maintain hemoglobin levels when given three-times weekly, for 29 days. This study will describe the relationship between hemoglobin and GSK1278863 given three-times weekly. The data from this study will allow for conversion of once daily doses to three-times weekly doses.

Hospitalization & Mortality in Patients With Iron Deficiency CKD and HF Treated With i.v. Iron....

Iron DeficiencyHeart Failure1 more

Iron deficiency, independent of anemia, appears to increase morbidity and mortality as well as impairing health-related quality of life in chronic heart failure (CHF), and these effects are compounded when patients also experience chronic kidney disease (CKD). This study was designed to determine the effects of intravenous iron treatment on morbidity and mortality following an initial 6-month period and a longer period of up to 5 years.

Glargine Versus NPH in Patients With Chronic Kidney Disease

Type 2 Diabetes MellitusChronic Kidney Disease

Chronic kidney disease (CKD) is one of the most common microvascular complications of diabetes mellitus, and it is the leading cause of end stage renal disease on developed countries. The CKD diagnosis and its progression require re-evaluation of hypoglycemic therapy and constant dosing adjustments, in order to optimize glycemic control and minimize its side effects. Long acting insulin analogs and its pharmacokinetics have not been studied through different stages of kidney disease and there is no consensus defining the appropriate dosing adjustment based on the glomerular filtration rate (GFR). This research project will compare the glycemic response to intensive insulin treatment with NPH insulin and basal insulin analog (insulin glargine) in type 2 diabetes (DM 2) patients with CKD stages 3 and 4. Patients and methods - Inclusion Criteria: DM 2 patients with CKD secondary to diabetic nephropathy and GFR of 15-59 ml/min/1.73m². Exclusion Criteria: Patients with systemic neoplasia, HIV, CKD or nephropathy from other etiologies, severe psychiatric disorders and pregnant women. Study design: This study consists of a randomized, cross-over, open-label controlled clinical trial. Patients will be randomly divided into two groups: GROUP 1 - insulin analog glargine once a day and GROUP 2 - NPH human insulin, three applications per day, both group will be treated with insulin lispro at mealtime. The laboratory tests will be performed at baseline and 12, 24, 36 and 48 weeks after the study start. During routine medical appointments will be analyzed self- monitoring of capillary blood glucose (SMBG) and the hypoglycemia score. After 24 weeks the basal insulin will be changed, i.e. patients using NPH insulin will receive insulin glargine and patients on insulin glargine will be changed to NPH insulin. A CGMS will be carried out at 24 and 48 weeks. Methodology: The metabolic profile will be evaluated throughout SMBG; biochemical, hormonal and hematological measurements; hypoglycemia score and CGMS. Statistical analysis will be performed using comparative descriptive analyzes, such as chi-square distribution, t-test and non-parametric tests. Analyze of data CGMS will include the area under the curve and the related statistic. Finally, logistic regression models will be adopted to evaluate the effect of the treatment on the several variables in question.

A Study of Vonapanitase (PRT-201) Administered Immediately After Radiocephalic Arteriovenous Fistula(AVF)...

Chronic Kidney Disease

This research study is designed to assess the safety and effectiveness of an experimental drug called vonapanitase (PRT-201) in patients both receiving or expecting to receive hemodialysis who have chronic kidney disease and who are undergoing surgery to create a new access point to their bloodstream for hemodialysis. Vonapanitase is a protein that has been shown in previous research studies to help keep vessels patent when applied to the outside surface of the blood vessels (arteries and veins) in patients who undergo surgery to create an arteriovenous fistula (AVF). The purpose of this study is to determine whether vonapanitase when applied to a limited segment of your blood vessel (about 2 inches) immediately after surgery is safe and improves the patency of your AVF.
