End Stage Renal DiseaseNCT03261154
Serum iPTH, Calcium and Phosphate, and the Risk of Mortality in Beijing Elderly Hemodialysis Population
An observational study of End Stage Renal Disease, run by Wenhu Liu at 1 site in China.
Trial summary
Incidence of End Stage Renal Disease (ESRD) amongst elderly patient group is continuously increasing with population aging progressing. Mineral and bone disorder (MBD) is a common complication caused by ESRD, it raises the incidence of cardiovascular disease (CVD) in hemodialysis patients, as well as mortality.

About this study
Incidence of End Stage Renal Disease (ESRD) amongst elderly patient group is continuously increasing with population aging progressing. Mineral and bone disorder (MBD) is a common complication caused by ESRD, it raises the incidence of cardiovascular disease (CVD) in hemodialysis patients, as well as mortality.
Joint effects of Kidney failure and aging on elderly hemodialysis patients make the contribution factors of CKD-MBD quite complex, and it also leads to differences in clinic manifestation between elderly hemodialysis patients and non-elderly hemodialysis patients. Since not much studies had been done for this specific subject, thus, research on elderly patients who is taking Maintenance hemodialysis is very necessary. This study is a retrospective research to identify optimized target value of Calcium and Phosphorus for elderly patients taking maintenance hemodialysis and hence provide guidance for clinical practices. The data for this study will be provided by Beijing Blood Purification Quality Control and Improvement Center. Clinical files and Calcium and Phosphorus metabolic indices will be collected amongst elderly patients who were elder than 65 years and was taking maintenance hemodialysis between Jan 1st, 2012 through Dec 31st, 2016. Relationship between Calcium level, Phosphorus level, iPTH index, all-cause mortality and CVD caused mortality will be analyzed to identify optimized range of target Calcium levels, Phosphorus level for hemodialysis treatment

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Incidence of End Stage Renal Disease (ESRD) amongst elderly patient group is continuously increasing with population aging progressing. Mineral and bone disorder (MBD) is a common complication caused by ESRD, it raises the incidence of cardiovascular disease (CVD) in hemodialysis patients, as well as mortality.
Joint effects of Kidney failure and aging on elderly hemodialysis patients make the contribution factors of CKD-MBD quite complex, and it also leads to differences in clinic manifestation between elderly hemodialysis patients and non-elderly hemodialysis patients. Since not much studies had been done for this specific subject, thus, research on elderly patients who is taking Maintenance hemodialysis is very necessary. This study is a retrospective research to identify optimized target value of Calcium and Phosphorus for elderly patients taking maintenance hemodialysis and hence provide guidance for clinical practices. The data for this study will be provided by Beijing Blood Purification Quality Control and Improvement Center. Clinical files and Calcium and Phosphorus metabolic indices will be collected amongst elderly patients who were elder than 65 years and was taking maintenance hemodialysis between Jan 1st, 2012 through Dec 31st, 2016. Relationship between Calcium level, Phosphorus level, iPTH index, all-cause mortality and CVD caused mortality will be analyzed to identify optimized range of target Calcium levels, Phosphorus level for hemodialysis treatment

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
All-cause mortality (time frame: 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Aug 2017.
