Highlights
- •Carotid intima-media thickness (CIMT) was associated with chronic kidney disease (CKD) in participants with a high CD34+ cell count.
- •No association was observed for participants with a low CD34+ cell count.
- •Endothelial repair activity might determine those associations.
Abstract
Background and aims
Endothelial injury is well-known as a process that can lead to chronic kidney disease
(CKD) and atherosclerosis. Hematopoietic activity is known to be associated inversely
with CKD and positively with atherosclerosis. Since bone-derived progenitor cells
(CD34-positive cells) contribute to endothelial repair (including the progression
of atherosclerosis), understanding the association between CKD and carotid intima-media
thickness (CIMT), in relation to circulating CD34-positive cell count, may be an efficient
means of clarifying the mechanisms underlying endothelial activity.
Methods
We conducted a cross-sectional study of 570 elderly Japanese men aged 60–69 years,
who underwent a general health check-up. Participants were stratified as per a median
circulating CD34-positive cell count (1.01 cells/μL).
Results
Independent of the known cardiovascular risk factors, CIMT was found to be positively
associated with CKD in the participants with high circulating CD34-positive cell counts
but not in participants with low counts. Odds ratios were 1.40 (1.04, 1.89) for participants
with high and 1.01 (0.72, 1.43) for participants with low circulating CD34-positive
cell counts after adjustment for known cardiovascular risk factors at 95% confidence
intervals for CKD with one standard deviation increment of CIMT.
Conclusions
A positive association between CIMT and CKD was observed among participants with high
circulating CD34-positive cell counts but not among participants with low counts.
Endothelial repair activity might determine the association between CKD and CIMT.
