Insights
Sevelamer hydrochloride did not impact cardiovascular calcification in hemodialysis patients compared to calcium binders. However, sevelamer use showed trends toward lower C-reactive protein and higher alkaline phosphatase and parathyroid hormone levels.
Area of Science:
- Nephrology
- Cardiology
- Biochemistry
Background:
- Patients with cardiovascular disease on hemodialysis often experience accelerated cardiovascular calcification.
- Phosphate binders are crucial for managing hyperphosphatemia in these patients.
- Sevelamer hydrochloride and calcium-based binders are common therapeutic options.
Purpose of the Study:
- To compare the effects of sevelamer hydrochloride versus calcium-based phosphate binders.
- To evaluate impacts on coronary artery calcification, C-reactive protein, alkaline phosphatase, and intact parathyroid hormone.
- To analyze data from a meta-analysis of relevant clinical trials.
Main Methods:
- A meta-analysis was conducted using studies retrieved via Medline, Cochrane Library, and conference proceedings.
- Keywords "sevelamer" and "Renagel" were utilized for study identification.
- Eligibility, quality assessment, data abstraction, and analysis were performed on selected trials.
Main Results:
- Fourteen studies with 3,271 patients were included in the analysis.
- No significant difference in coronary artery calcium progression was observed between sevelamer and calcium groups.
- Sevelamer use was associated with significantly lower C-reactive protein and higher alkaline phosphatase and intact parathyroid hormone levels.
Conclusions:
- Sevelamer treatment did not alter cardiovascular calcification progression in hemodialysis patients.
- A trend towards reduced C-reactive protein levels was noted with sevelamer.
- Elevated alkaline phosphatase and intact parathyroid hormone levels were observed in the sevelamer group.
Background:
Accelerated cardiovascular calcification often occurs in patients with cardiovascular disease who are on hemodialysis. We performed a meta-analysis to compare the effects of sevelamer hydrochloride and calcium-based phosphate binders on coronary artery calcification, C-reactive protein, alkaline phosphatase and intact parathyroid hormone in patients undergoing hemodialysis.
Methods:
We used the key words 'sevelamer' and 'Renagel' to retrieve studies from Medline, the Cochrane Library and conference proceedings. The trials searched were evaluated for eligibility and quality, and then the data were abstracted and analyzed.
Results:
We ultimately included 14 studies that enrolled a total of 3,271 patients. There was no difference in coronary artery calcium progression between the calcium and the sevelamer groups. Use of sevelamer, rather than calcium-based phosphate binders, was associated with significantly lower C-reactive protein levels (weighted mean difference (WMD) -1.42; 95% confidence interval (CI) -2.09 to -0.74), higher alkaline phosphatase levels (WMD 22.66; 95% CI 13.81-31.5) and higher intact parathyroid hormone levels (WMD 55.85; 95% CI 14.47-97.24).
Conclusions:
Treatment with sevelamer did not affect cardiovascular calcification, but there was a trend for lower C-reactive protein levels, higher alkaline phosphatase levels and intact parathyroid hormone levels among sevelamer-treated patients.

Study Designs in Epidemiology
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.
