BACKGROUND AND OBJECTIVES: Cardiovascular outcomes and mortality rates are poor
in advanced chronic kidney disease (CKD) patients. Novel risk factors related to
clinical outcomes should be identified. METHODS: A retrospective analysis of data
from a randomized controlled study was performed in 440 CKD patients aged > 18
years, with estimated glomerular filtration rate 15-60 mL/min/1.73m2. Clinical
data were available, and the albumin-adjusted serum anion gap (A-SAG) could be
calculated. The outcome analyzed was all-cause mortality. RESULTS: Of 440
participants, the median (interquartile range, IQR) follow-up duration was 5.1
(3.0-5.5) years. During the follow-up duration, 29 participants died (all-cause
mortality 6.6%). The area under the receiver operating characteristic curve of
A-SAG for all-cause mortality was 0.616 (95% CI 0.520-0.712, P = 0.037). The best
threshold of A-SAG for all-cause mortality was 9.48 mmol/L, with sensitivity
0.793 and specificity 0.431. After adjusting for confounders, A-SAG above 9.48
mmol/L was independently associated with increased risk of all-cause mortality,
with hazard ratio 2.968 (95% CI 1.143-7.708, P = 0.025). In our study, serum
levels of beta-2 microglobulin and blood urea nitrogen (BUN) were positively
associated with A-SAG. CONCLUSIONS: A-SAG is an independent risk factor for
all-cause mortality in advanced CKD patients. The positive correlation between
A-SAG and serum beta-2 microglobulin or BUN might be a potential reason. Future
study is needed. TRIAL REGISTRATION: Clinicaltrials.gov NCT 00860431.
