Trial summary

Hyperphosphatemia and elevated cardiac biomarkers are two key characteristics of patients in end stage renal diseases(ESRD),however the majority of whom are in the absence of acute coronary syndrome(ACS). And it is still unclear why cardiac biomarkers would increase in those patients. Read more about this study

About this study

Hyperphosphatemia and elevated cardiac biomarkers are two key characteristics of patients in end stage renal diseases(ESRD),however the majority of whom are in the absence of acute coronary syndrome(ACS). And it is still unclear why cardiac biomarkers would increase in those patients. We hypothesized that excessive phosphorus is account for that phenomenon.To confirm that hypothesis,we used one phosphorus binder to reduce phosphorus absorption in hemodialysis patients for some time and observed the change of cardiac biomarkers of those patients.

Read the detailed description

Cardiovascular disease is one of the leading causes of morbidity and mortality in patient with chronic kidney disease(CKD), accounting for more than 50% of all deaths.When myocardial cells get injured, cardiac biomarkers will be released into the circulation. Elevated cardiac biomarkers have been observed in patients with various degrees of renal failure. However, the majority of those CKD patients are in the absence of acute coronary syndrome. So far, it is still unclear the mechanisms of the increased biomarkers in CKD patients. Meanwhile, hyperphosphatemia is one of the major features of CKD, particularly of end stage renal disease(ESRD). Lots of evidences have shown that high levels of serum phosphorus and an elevation of the serum calcium × phosphorus product can lead to cardiovascular calcifications and subsequent cardiovascular morbidity and mortality in patients with CKD.it is tempting to hypothesize that hyperphosphatemia may be responsible for the rise of cardiac biomarkers in CKD patients.So we use one phosphate binder to reduce phosphorus absorption in hemodialysis patients for one year and observe the change of cardiac biomarkers of those patients.

Questions about this trial

What is this clinical trial studying?

An observational study of End Stage Renal Failure, run by Shanghai 10th People's Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Ai Peng, Ph.D,M.D (86-021-66302524, pengai@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Reducing cardiac biomarkers in hemodialysis patients (time frame: 6 months). 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 17 Mar 2015.
