History of Changes
  Purpose

The purpose of this study is to perform a randomized, controlled clinical trial to investigate if the phosphate binder sevelamer can improve insulin resistance and glucose handling in patients receiving maintenance hemodialysis.

Primary Outcome Measures:
  • Change in insulin sensitivity and/or glucose tolerance from baseline to the end of the study, as obtained by ISIOGTT. [ Time Frame: Week 12 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change from baseline to the end of the trial in surrogate markers of phosphate balance (PTH, s-urea, s-creatinine, ionized Ca, phosphate). [ Time Frame: Week 12 ] [ Designated as safety issue: Yes ]
  • Change from baseline to end of the study in markers of lipid homeostasis (total cholesterol, LDL, HDL, ApoA, ApoB, TG, free fatty acids) [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
  • Change from baseline to the end of the study in circulating inflammatory cytokines (hsCRP, TNF, fibrinogen, PAI, fetuin) [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
  • Number of adverse events directly attributable to sevelamer or calciumcarbonate treatments. [ Time Frame: Weekly until end of study ] [ Designated as safety issue: Yes ]

Arms Assigned Interventions
Experimental: 1
Sevelamer intervention
 Drug: Sevelamer
sevelamer tablets, 800 mg (Renagel(r), Genzyme Inc). The initial daily dose of sevelamer will be 2400 mg (800 mg x 3). After the first week of treatment the dose will be increased to 4800 mg. If treatment with sevelamer is well tolerated and if a phosphate concentration of <1.8 mmol/l is not obtained, the dose may be increased further. The maximum daily dose of sevelamer will be 9600 mg. If a patient experiences side effects, the dose of sevelamer will be reduced to the highest acceptable dose, and, if a phosphate concentration of <1.8 mmol/l is not obtained, the treatment will be supplemented with calcium carbonate in a dose tolerated by the patient.
Other Name: Renagel
Active Comparator: 2
Calcium carbonate
 Drug: Calcium carbonate
Calcium carbonate tablets, 250 mg (Kalcidon, Abigo AB). Calcium carbonate will be prescribed at the dose given prior to the washout period. The dose will be adjusted weekly to obtain a serum phosphate concentration <1.8 mmol/l.
