Animal models of kidney disease have linked metabolic acidosis with renal damage. The role of low serum bicarbonate levels in kidney disease progression in humans has not been studied. Retrospective cohort study. Setting & Participants: Adults visiting a medical clinic in the Bronx, NY from 01/01/01 to 12/31/03 were included in the study (n=5,422) and followed until 6/30/07 Serum bicarbonate levels Kidney disease progression was defined as either a decline in the estimated glomerular filtration rate (eGFR) by 50% or reaching an eGFR of <15 ml/min/1.73m2 (n=337). Patients’ baseline demographics, comorbidities, laboratory data and socioeconomic status were recorded. Serial outpatient serum creatinines were collected (median, 5 measurements/ person). The mean age was 52 years, 69% were women, 45% were African-American, 31% were Hispanic, 21% had diabetes mellitus, 41% had hypertension, and 9% had a baseline eGFR <60 ml/min/1.73m2. Kidney disease progressed by the definition above in 337 patients (6.2%). Compared to the reference group (bicarbonate level 25-26 mEq/L), the hazard ratio for progression after adjustment for potential confounders was 1.54 (95% CI 1.13-2.09) for bicarbonate levels ≤22 mEq/L, 0.97 (95% CI 0.70-1.35) for levels 23-24 mEq/L and 1.14 (95% CI 0.84-1.55) for levels ≥27 mEq/L. (Global p-value for inclusion of serum bicarbonate in the model, 0.01). These results remained similar when using different definitions of the outcome (an eGFR decline by 30%, 1288 outcomes (24%)) or doubling of serum creatinine (268 outcomes (4.9%)). Data used in study was collected for clinical, not research, purposes. Low serum bicarbonate is associated with the progression of kidney disease, independent of baseline eGFR and other clinical, demographic and socioeconomic factors. Prospective studies are needed to confirm this relationship and to evaluate the efficacy of alkali supplements for slowing progression.
