Pilot Trial of Oral Sodium Bicarbonate Versus Higher Dialysate Bicarbonate in Hemodialysis Patients With Metabolic Acidosis (Bicarbonate-HD)

July 18, 2026 updated by: Azza KHEDHIRI, University of Sfax

Comparative Pilot Trial of Oral Sodium Bicarbonate Versus Increased Dialysate Bicarbonate in Chronic Hemodialysis Patients With Metabolic Acidosis

Metabolic acidosis is frequent in chronic hemodialysis patients and is associated with adverse clinical outcomes. Two commonly used strategies to correct acidosis are oral sodium bicarbonate supplementation and increasing the bicarbonate concentration of the dialysate, but their comparative effectiveness and tolerance in routine care remain uncertain. This pilot, prospective, randomized, open-label, single-center trial will compare oral sodium bicarbonate versus higher dialysate bicarbonate in chronic hemodialysis patients with metabolic acidosis, using predialysis plasma bicarbonate concentrations, so-called "reserves alcalines" or "alkaline reserves" in local laboratory reports, as a pragmatic marker of acid-base status.

Approximately 30 acidotic patients (serum bicarbonate < 22 mmol/L) will be randomized 1:1 to receive either oral sodium bicarbonate or an increase in dialysate bicarbonate for 6 weeks. An additional non-acidotic observational group will provide descriptive reference data. The primary outcome is the change in predialysis serum bicarbonate from baseline (Day 0) to Day 42 between the two randomized arms. Secondary outcomes include the proportion of patients reaching target serum bicarbonate levels, the weekly kinetics of correction, dialysis adequacy (Kt/V and online clearance monitoring), intradialytic tolerance (blood pressure, cramps, hypotension, symptoms), sodium-related safety (natremia, interdialytic weight gain), and the effects of acidosis correction on nutritional and bone-mineral metabolism, including changes in serum albumin, calcium, phosphorus, and parathyroid hormone (PTH). Feasibility indicators such as recruitment, retention, adherence to treatment and dialysate adjustment, and data completeness will also be described to inform the design of a larger definitive trial.

Detailed Description

Metabolic acidosis is a common complication in chronic hemodialysis patients and is associated with adverse nutritional, cardiovascular, and bone outcomes. In clinical practice, two main strategies are used to correct acidosis: oral sodium bicarbonate supplementation and increasing the bicarbonate concentration of the dialysate. Both approaches are recommended in guidelines, but their comparative effectiveness and tolerance in routine hemodialysis care, particularly in resource-limited settings, remain uncertain.

This pilot, prospective, randomized, open-label, single-center study will compare these two strategies in adult chronic hemodialysis patients with metabolic acidosis, defined by low predialysis serum (or plasma) bicarbonate concentrations, so-called "reserves alcalines" or "alkaline reserves" in local laboratory reports. Approximately 30 acidotic patients (serum bicarbonate < 22 mmol/L) will be enrolled and randomized in a 1:1 ratio to either oral sodium bicarbonate supplementation (Arm A) or an increase in dialysate bicarbonate concentration (Arm B) for 6 weeks. In addition, a non-acidotic observational control group of hemodialysis patients with stable, adequate serum bicarbonate levels will be followed descriptively to provide reference data on acid-base status, dialysis adequacy, and tolerance.

Randomization among acidotic patients will be performed after matching them in pairs according to the severity of metabolic acidosis (baseline predialysis serum bicarbonate / "reserves alcalines") and age. Patients will be ordered from the lowest to the highest serum bicarbonate value, then matched two-by-two on similar bicarbonate level and age. Within each pair, allocation to oral sodium bicarbonate (Arm A) or increased dialysate bicarbonate (Arm B) will be determined by a computer-generated random number in a spreadsheet, corresponding to a block randomization with block size 2 after matching on acidosis severity. The non-acidotic control group will not be randomized and will receive usual care.

The primary outcome is the change in predialysis serum bicarbonate from baseline (Day 0) to Day 42, comparing the two randomized arms. Secondary outcomes include the proportion of patients achieving target serum bicarbonate at Day 42, the weekly kinetics of bicarbonate correction over 6 weeks, changes in serum potassium, and dialysis adequacy assessed by Kt/V and online clearance monitoring. Intradialytic and interdialytic tolerance will be evaluated through blood pressure, interdialytic weight gain, cramps, hypotension, thirst, digestive symptoms, and any treatment discontinuation or dose reduction related to intolerance. Sodium-related safety will be assessed by predialysis natremia and interdialytic weight gain, given the potential impact of both oral sodium bicarbonate and higher dialysate bicarbonate on sodium load.

As a pilot trial, this study also includes predefined feasibility objectives. Feasibility outcomes will describe recruitment and retention rates, adherence to oral treatment and to the dialysate bicarbonate adjustment algorithm, and data completeness for key clinical and laboratory variables. These feasibility indicators will be used to judge the practicality of the protocol and to inform the design and assumptions of a larger, definitive randomized controlled trial.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Oral Sodium Bicarbonate Arm
Adult chronic hemodialysis patients with metabolic acidosis (serum/plasma bicarbonate < 22 mmol/L) randomized to receive oral sodium bicarbonate supplementation according to a stepwise dosing algorithm based on weekly predialysis serum bicarbonate ("reserves alcalines").
Dietary supplement: Oral sodium bicarbonate
Oral sodium bicarbonate given as Bicardis 500 mg capsules, used as a dietary supplement in Tunisia, administered according to a standardized algorithm based on predialysis serum bicarbonate concentrations, so-called "reserves alcalines" in local laboratory reports. At baseline, an initial dose is prescribed according to the severity of metabolic acidosis: 1 capsule/day if 20-21.9, 2 capsules/day if 18-19.9, 3 capsules/day if 16-17.9, 4 capsules/day if <16 mmol/L. At each weekly visit, the same dose is maintained if reserves alcalines remain below the target range and the weekly increase is ≤ 3 mmol/L; the dose is reduced to the previous lower level if the weekly increase is > 3 mmol/L or if predialysis bicarbonate enters the predefined target range (22-24 mmol/L); oral bicarbonate is reduced or stopped if predialysis bicarbonate exceeds the upper limit of the target range (> 24 mmol/L) to avoid alkalosis, and the dose is increased if reserves alcalines do not improve or decrease.
Other Names:
  • Bicardis
Active Comparator: Increased Dialysate Bicarbonate Arm
Adult chronic hemodialysis patients with metabolic acidosis (serum/plasma bicarbonate < 22 mmol/L) randomized to receive an increased dialysate bicarbonate concentration according to a predefined stepwise algorithm based on weekly predialysis serum bicarbonate ("reserves alcalines" or "alkaline reserves" in local laboratory reports).
Other: Increased Dialysate Bicarbonate

Adjustment of the dialysate bicarbonate concentration will be performed according to a standardized titration strategy based on predialysis serum bicarbonate concentrations ("reserves alcalines" in local laboratory reports). At baseline, an initial increase in dialysate bicarbonate is prescribed according to the severity of metabolic acidosis: +1 mmol/L if serum bicarbonate is 20-21.9 mmol/L, +2 mmol/L if 18-19.9 mmol/L, +3 mmol/L if 16-17.9 mmol/L, and a larger or individualized increase if < 16 mmol/L.

At each weekly visit, dialysate bicarbonate is then adjusted as follows: it is maintained if reserves alcalines remain below the target range and the weekly increase is ≤ 3 mmol/L; it is reduced to the previous lower level if the weekly increase is > 3 mmol/L or if predialysis bicarbonate enters the predefined target range (22-24 mmol/L); and it is reduced or returned to the standard level if predialysis bicarbonate exceeds the upper limit of the target range (> 24 mmol/L).
No Intervention: Non-Acidotic Hemodialysis Control Group
Adult chronic hemodialysis patients with stable, adequate predialysis serum (or plasma) bicarbonate concentrations (so-called "reserves alcalines" or "alkaline reserves" in local laboratory reports), who are not acidotic according to the study definition, will be included as a non-randomized observational control group. These patients will continue their usual dialysis prescription and routine care without any specific study-mandated change in oral bicarbonate or dialysate bicarbonate. They will be followed over the same 6-week period with collection of serum bicarbonate, sodium, potassium, dialysis adequacy (Kt/V and online clearance monitoring), blood pressure, interdialytic weight gain, and intradialytic symptoms, to provide descriptive reference data on acid-base status, dialysis adequacy, and tolerance in non-acidotic hemodialysis patients
