A randomized controlled trial of a bicarbonate- and a bicarbonate/lactate-containing dialysis solution in CAPD.
OBJECTIVE
To evaluate the safety and efficacy of bicarbonate- and bicarbonate/lactate-based PD fluids.


METHODS
A randomly allocated prospective controlled trial lasting eight weeks.


METHODS
Five renal units in Europe.


METHODS
Individuals who have been treated by CAPD for at least three months and who have had at least one month's therapy with 40 mmol/L lactate PD fluid. Those with recent infection, diabetes or other serious illness are excluded. Forty-seven individuals have entered the study so far.


METHODS
Patients are randomly allocated to three groups. Group 1 receive 40 mmol/L lactate dialysate, Group 2 are given 38 mmol/L bicarbonate fluid and Group 3 are tested with a 25 mmol/L bicarbonate and 15 mmol/L lactate dialysate.


METHODS
The primary outcome measure is the plasma bicarbonate level. Adverse events and ease of use of the two-chambered bags used by Groups 2 and 3 are also being assessed.


RESULTS
To date, plasma bicarbonate levels have been the same in all treatment groups up to the end of the trial period. There are no differences in serum lactate levels. No side effects are attributable to the test fluids. The patients have managed the two-chambered bags successfully.


CONCLUSIONS
This trial is still ongoing, but to date, neutral bicarbonate based fluids have been as effective as lactate dialysate in treating uremic acidosis.
