Filter by:The MBD-5D is a prospective observational study with a case-cohort and a cohort design. Eligible patients are receiving hemodialysis and have secondary hyperparathyroidism. The study's three goals are (1) to record the patients' characteristics, and variation in the patterns of their treatment; (2) to analyze factors associated with variation in those medical practice patterns; and (3) to identify practice patterns and other factors that affect hospitalization, mortality, and other patient-level outcomes.
The purpose of this study is to measure the effect of a reduced calorie diet intervention in new kidney transplant recipients on the outcomes weight gain, oxidative stress, and insulin resistance.
Phase IIIb study to evaluate the long-term efficacy of ferric carboxymaltose (FCM) (using targeted ferritin levels to determine dosing) or oral iron in non-dialysis-dependent chronic kidney disease (NDD-CKD) subjects with iron deficiency anaemia (IDA).
This study is a exploratory comparison of the efficacy and safety of paricalcitol injection with maxacalcitol injection in chronic kidney disease participants receiving hemodialysis with secondary hyperparathyroidism.
The purpose of the study is to demonstrate the safety and immunogenicity of a new investigational hepatitis B virus vaccine, HEPLISAV-B, in patients 18 to 75 years of age who have progressive loss of kidney function.
In this prospective study, the investigators aimed to evaluate the effects of improved hyperuricemia, a minor cardiovascular risk factor, on endothelial dysfunction in patients with chronic kidney disease.
Evaluates the effectiveness of on-label Paricalcitol versus Cinacalcet with Low-Dose Vitamin D.
Hyperparathyroidism (HPT) is common in people with a kidney transplant. Patients with HPT often have high parathyroid hormone (PTH) levels and may have large parathyroid glands in the neck. Patients with HPT can develop bone disease (osteodystrophy). This bone disease can cause bone pain, fractures, and poor formation of red blood cells. Other problems from HPT may include increases in blood levels of calcium (hypercalcemia) and low blood levels of phosphorus (hypophosphatemia). The high calcium levels may cause calcium to deposit in body tissues. Calcium deposits can cause arthritis (joint pain and swelling), muscle inflammation, itching, gangrene (death of soft tissue), heart and lung problems or kidney transplant dysfunction (worsening of kidney transplant function). The purpose of this study is to evaluate the effects of cinacalcet (Sensipar/Mimpara) on high calcium levels in the blood in patients with HPT after a kidney transplant.
ABSTRACT Background: It is well recognized that excess dietary salt intake plays a major role in the development of hypertension. Chronic Kidney Disease (CKD) is associated with excess salt and water retention (excess volume) which is associated with hypertension. Hypotheses: Hypothesis 1: Dietary salt restriction will improve volume status in subjects with CKD stages 3-4 as assessed by Bioelectrical Impedance Analysis (BIA). Hypothesis 2: Dietary salt restriction will result in improved blood pressure control in patients with CKD stages 3-4. Hypothesis 3: Dietary salt restriction will decrease albuminuria in patients with CKD stages 3-4. Patients and Trial Design: This randomized crossover pilot study is designed to assess the effect of salt restriction on volume status in patients with CKD stages 3 and 4. Subjects will be randomized to a treatment order: (1) 4 weeks of salt restriction of <85 mmol sodium per day, a 2 week washout period, and 4 weeks of usual salt diet, OR (2) 4 weeks of usual diet, 2 weeks washout, and 4 weeks of salt restriction. Patients will receive dietary counseling in person at each study visit and at weekly intervals by phone calls from study dieticians. At weeks 0, 4, 6 and 10, patients will undergo assessments for (i) physical examination with assessments for weight, blood pressure, pulse, anthropometrics and a standardized clinical assessment of volume status. (ii) volume status using bioelectrical impedance analysis (BIA) (iii) 24-hour urine testing for, albumin, creatinine and aldosterone Every 2 weeks throughout the study, a 24-hour urine sodium will be measured for compliance, and serum electrolytes will be assessed for safety. Data Analysis: BIA measurements in the low salt group will be compared with the regular diet group using the standard linear model analysis for 2x2 crossover trials. Additionally, 24-hour ambulatory and static blood pressure and 24-hour urine aldosterone levels will be compared between the two groups. Future Implications: A significant reduction in the degree of volume expansion (as assessed by BIA) and blood pressure as a result of a salt restricted diet would have implications for renal and cardiovascular protection and would warrant confirmation by a larger randomized trial.
Subjects with normal kidney function are able to excrete in their urine the calcium and phosphorus absorbed via the gastrointestinal tract and are thereby are able to maintain calcium and phosphorus balance. Patients with chronic kidney disease often have normal blood levels of calcium and phosphorus but no research has been conducted to determine if they are able to excrete their daily intake of these minerals. If they are not able to excrete their daily intake, these minerals could be deposited in soft tissue and blood vessels and contribute to the increased risk of cardiovascular disease seen in patients with chronic kidney disease. This study will determine if subjects with chronic kidney disease are in balance primarily with regard to calcium and at what level of kidney function they are no longer able to maintain balance. Understanding whether patients with chronic kidney disease are in balance will help direct future therapeutic interventions.
