Active clinical trials for "Kidney Diseases"

Chronic kidney disease (CKD) is defined as persistent abnormalities of kidney structure or function for more than 3 months leading to a sustained reduction in glomerular filtration rate (GFR) and/or to the occurrence of kidney damage markers, such as albuminuria. [1] CKD is an emerging global public health problem, having significant morbidity and mortality costs on society. It is considered as an important component of the epidemic of non-communicable diseases in developed, as well as low-income/middle-income countries. [2] In the Kingdom of Saudi Arabia, CKD has been established as a major health issue in recent decades due to the growing incidence and prevalence of end stage kidney disease (ESKD) among the Saudi population. The overall prevalence of CKD was 5.7% in 2010. [3] In 2017, there were around two million cases of CKD and 3818 deaths due to CKD in Saudi Arabia in 2017. [4] A recent study also reported the overall prevalence of CKD stages 3 to 5 was 4.4% among the Saudi population. [5] The major consequences of CKD include disease progression and, subsequently, increased risk of cardiovascular disease.

Hyperphosphatemia is a common problem among patientens suffering from chronic kidney disease. Hyperphosphatemia is associated with increased risk of cardiovascular diseases. One of the treatments are through the diet, where patients are instructed ind reducing their daily intake of phosphate. But since phosphate exists in both organic and inorganic forms in the diet, this leads to several problems. Informations of the bioavability and furthermore the effect of plasma koncentrations of phosphate are lacking for both forms of phosphate.

The visceral adiposity index (VAI) has been developed, an indicator for the metabolic function of VAT. Previous studies have confirmed the association between the VAI and CKD prevalence. In this study, we attempted to investigate the association between estimated glomerular filtration rate (eGFR) decline and visceral adiposity.

This is an observational clinical research on patients with chronic kidney disease who are not on hemodialysis and receiving darbepoetin alfa to treat diagnosed renal anemia; the major objective is to explore novel erythropoiesis stimulating agent (ESA) response index in association with deterioration of renal function as well as occurrence of cardiovascular disease events.

Studies suggest that dietary omega-3 fatty acids influence the extent to which the time interval between each heart beat varies (heart rate variability; HRV). Low HRV is associated with increased risk of sudden cardiac death (SCD). The purpose of this research is to investigate the relationship between 24 hour parameters of HRV and blood omega-3 fatty acid levels in patients who have recently commenced haemodialysis.

Improve health and outcome for people with late stage chronic kidney disease by providing patient centered nursing services in addition to a Nephrologist's routine patient care.

This observational study will evaluate the efficacy and use of Methoxy polyethylene glycol-epoetin beta (Mircera) in participants with Stage V chronic kidney disease on hemodialysis receiving an erythropoietin prior to study entry. Attending physicians should have made the decision of placing the participant on methoxy polyethylene glycol epoetin beta in advance and not related to the study. The therapy will be administered by the attendant treating physician according to specifications in the package insert guidelines and to the routine of the site.

This is an open label clinical study designed to evaluate the safety and immunogenicity of Sci-B-Vac Hepatitis B Vaccine compared to Engerix-B Hepatitis B Vaccine in dialysis patients. The study hypothesis is that vaccination with Sci B Vac will achieve a higher seroprotection rate and a higher anti-Hepatitis B surface antibody serum titer level than vaccination with Engerix-B Dialysis patients will be categorized as "naïve" or "previously vaccinated" and each group will be randomized to treatment. Naïve patients randomized to Sci-B-Vac Hepatitis B vaccine will receive vaccination in three doses, 10 μg each, at 0, 1, and 6 months, or Engerix-B Hepatitis B vaccine given in four doses, 40 μg each, at 0, 1, 2, and 6 months. Previously vaccinated patients randomized to Sci-B-Vac Hepatitis B vaccine will receive vaccination in three doses, 20 μg each, at 0, 1, and 6 months, or Engerix-B Hepatitis B vaccine given in four doses, 40 μg each, at 0, 1, 2, and 6 months. All vaccines will be administered via intra-muscular injection to the deltoid muscle. The study will consist of three periods: a screening period of up to four weeks, a 24-week open-label treatment period, and a 24-week safety follow-up period. The total expected duration of the study per subject is 52 weeks as follows: Screening period: approximately 4 weeks; treatment period: 24 weeks; and follow up period: 24 weeks. The primary endpoint is the by-vaccine difference in the proportion of subjects attaining seroprotective immune response (anti-Hepatitis B surface antibody ≥ 10 IU/mL) 4 weeks after the last vaccination with either Sci-B-Vac or Engerix-B. Secondary endpoints include anti-Hepatitis B surface antibody geometric mean concentrations calculated for all subjects upon last active dose; the proportion of subjects with anti-Hepatitis B surface antibody concentrations equal to or above 10 IU/mL for all subjects at 12 weeks following the first vaccine dose; the by-treatment difference in serum titer levels of anti-Hepatitis B surface antibodies at 12, 24 and 52 weeks following the first vaccination. A by-vaccine comparison of adverse events will also be performed.

Kidney transplantation is the treatment of choice for kidney failure in children. Kidney transplant recipients need to take immunosuppression for the rest of their lives after transplantation to prevent rejection of the graft. One of the important medications is called Tacrolimus which can prevent rejection of the kidney graft but at the same time is toxic to the kidney. Therefore, repeated blood levels of Tacrolimus with tests of kidney function will help physicians to prescribe the best dose for therapy to prevent kidney rejection and kidney toxicity. Failure of compliance with taking Tacrolimus is also an important cause of graft failure especially among teenagers, so repeated blood Tacrolimus levels are necessary to detect patients who fail to take their medications on a regular basis. We have developed a lab assay that measures Tacrolimus blood level and creatinine (for kidney function) using one dried blood spot (DBS) on filter paper similar to the filter paper used in the new born screen. We plan to teach patients how to do the test at home once a month and mail the filter paper back to OHSU for analysis for Tacrolimus and creatinine. The advantage of this method is that it is less painful for children then a regular blood dray from the vein, can be done easily at home, will be most cost effective as it will save the family a day of work or school and can detect both the Tacrolimus level and the kidney function at the same time. We will assess the effect of doing this simple finger prick at home on compliance, on Tacrolimus levels and kidney function over the study period of one year. We will also assess how satisfied patients are with this method instead of going to the lab or the hospital for blood test. All subjects will continue on their regular clinic visits and will continue to have their routine blood draws by intravenous method in the lab during the study.

This prospective observational study evaluated the efficacy and safety of Mircera (methoxy polyethylene glycol-epoetin beta) in chronic kidney disease participants on dialysis with renal anemia. Participants initiated on treatment with Mircera according to the Summary of Product Characteristics and standard clinical practice were followed for 10 months.
