Citrate Dialysis for Vascular Calcification
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether a special dialysis solution with citrate (Citrate Dialysate) can slow the hardening of blood vessels. Participants will use two different dialysis solutions over two years: one with citrate and one without (Standard Dialysate), to assess their effects. Researchers will monitor progress by taking mammograms and blood samples every six months. The trial seeks individuals already on hemodialysis who show specific signs of blood vessel hardening on their mammograms. As an unphased trial, it offers patients the chance to contribute to important research that could enhance future dialysis treatments.
Do I have to stop taking my current medications for the trial?
The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are currently using warfarin.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that citrate dialysate is generally well-tolerated in hemodialysis treatments. One study found that it improved dialysis efficiency and helped maintain stable blood pressure during treatments.
However, some sessions reported issues such as an imbalance of sodium in the blood in 15% of cases and a disturbance in the body's acid-base balance in 9.4% of cases. While important to consider, these issues were not common for most patients.
Overall, evidence suggests citrate dialysate is safe for many people. However, like any treatment, it may not be suitable for everyone. Concerns should be discussed with a healthcare provider to determine if this treatment is appropriate.12345Why are researchers excited about this trial?
Researchers are excited about using citrate dialysate for vascular calcification because it could offer a safer alternative to standard dialysate. Unlike traditional treatments that use an acidic concentrate, citrate dialysate helps to prevent calcium buildup in blood vessels by binding to calcium more effectively. This could lead to less vascular calcification, a common and dangerous issue for patients undergoing regular dialysis. By potentially reducing this risk, citrate dialysate might improve cardiovascular outcomes for these patients.
What evidence suggests that this trial's treatments could be effective for vascular calcification?
Research has shown that citrate dialysate might help reduce vascular calcification, the hardening of blood vessels. Some studies suggest that citrate can balance calcium levels in the body, potentially slowing this hardening. However, not all research agrees. One study found that citrate increased hardening, while another found no significant change. In this trial, participants will receive either citrate dialysate followed by standard dialysate or standard dialysate followed by citrate dialysate. These findings suggest that while citrate dialysate shows promise, its effect on blood vessel hardening remains uncertain and requires further research.24678

Are You a Good Fit for This Trial?
This trial is for hemodialysis patients who have vascular calcification visible on mammograms. It's not suitable for those with a life expectancy under 2 years, current warfarin users, individuals unable to consent, prisoners, or those with severe hyperparathyroidism or calcium control issues.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment Phase 1
Participants receive hemodialysis using either a citrate or non-citrate dialysate for 12 months
Treatment Phase 2
Participants switch to the alternate dialysate solution for another 12 months
Follow-up
Participants are monitored for safety and effectiveness after treatment
What Are the Treatments Tested in This Trial?
Interventions
- Citrate Dialysate
- Standard Dialysate
Trial Overview
The study tests if hemodialysis using citrate can slow down the hardening of blood vessels compared to standard dialysis solutions. Participants will use one solution for a year and then switch to the other for another year while their vascular health is monitored.
