Abstract
The elevated level of high-sensitivity C-reactive protein (HSCRP) is associated with
cognitive dysfunction, for which changes in the hippocampus plausibly play a pivotal
role. We tested the hypothesis that an elevated level of HSCRP correlates with hippocampus
volume and insulin resistance in nondementia patients with type 2 diabetes mellitus.
Subjects included 45 nondementia patients with type 2 diabetes mellitus, who were
divided into 2 groups: high-HSCRP group (age, 65 ± 6 years [mean ± SD]; n = 17) and
normal-HSCRP group (65 ± 7 years, n = 28). Hippocampus volume has been quantitated
with computer-assisted analysis using a magnetic resonance imaging voxel-based specific
regional analysis system developed for the study of Alzheimer disease (VSRAD), which
yields a z score as the end point for assessment of hippocampal volume. The z score was higher in the high-HSCRP group than in the normal-HSCRP group (P < .0001). The fasting plasma glucose (P < .05) and insulin concentrations (P < .0001) and the homeostasis model assessment (HOMA) index (P < .0001) were higher in the high-HSCRP group than in the normal-HSCRP group. Multiple
regression analysis showed that HSCRP levels were independently predicted by z score and HOMA index. Our results indicate that the elevated level of HSCRP in Japanese
nondementia patients with type 2 diabetes mellitus is characterized by increased hippocampus
volume and insulin resistance, and that the z score and HOMA index are independent predictors of HSCRP.
