Insights
High-sensitivity C-reactive protein (hs-CRP) and left ventricular hypertrophy (LVH) significantly increase cognitive impairment (CI) risk in hemodialysis patients. Managing these factors may help prevent CI in this population.
Area of Science:
- Nephrology
- Cardiology
- Neurology
- Biomarkers
Background:
- Cognitive impairment (CI) is a prevalent complication in patients undergoing hemodialysis (HD).
- Inflammation, indicated by high-sensitivity C-reactive protein (hs-CRP), and cardiac structural changes like left ventricular hypertrophy (LVH) are common in HD patients and may influence cognitive function.
Purpose of the Study:
- To investigate the individual and combined effects of hs-CRP and LVH on cognitive function in hemodialysis patients.
- To explore the relationship between hs-CRP levels, LVH status, and the risk of cognitive impairment (CI) in this cohort.
Main Methods:
- A cross-sectional study involving 232 hemodialysis patients.
- Cognitive function was assessed using the Beijing version of the Montreal Cognitive Assessment (MoCA-BJ).
- Logistic regression and EpiR package were used to analyze risk factors, including hs-CRP levels (categorized as low, intermediate, and high risk) and LVH status, and their synergistic effect on CI.
Main Results:
- Over half (52.59%) of the HD patients exhibited cognitive impairment (CI).
- Independent risk factors for CI included older age (OR = 1.048), left ventricular hypertrophy (LVH) (OR = 3.741), and high hs-CRP levels (>3 mg/L) (OR = 3.238).
- A significant synergistic effect was observed between high hs-CRP levels and LVH in increasing the risk of CI.
Conclusions:
- Age, LVH, and high hs-CRP levels are independent risk factors for cognitive impairment (CI) in hemodialysis patients.
- Patients with both high hs-CRP and LVH face a substantially elevated risk of CI.
- Strategies aimed at reducing hs-CRP levels and preventing LVH may be crucial for mitigating cognitive decline in hemodialysis patients.
Objectives:
To examine the effects of high-sensitivity C-reactive protein (hs-CRP) and left ventricular hypertrophy (LVH) on the cognitive function of hemodialysis (HD) patients, and to explore the relationship between hs-CRP, LVH, and cognitive impairment (CI).
Methods:
A cross-sectional study was conducted on 232 HD patients. Besides, general clinical data were gathered, and patients' cognitive functions were assessed using the Beijing version of the Montreal Cognitive Assessment (MoCA-BJ). CI risk factors were screened using logistic regression modeling based on hs-CRP values (low risk <1 mg/L, intermediate risk 1-3 mg/L, and high risk >3 mg/L) and LVH status (normal and hypertrophic) groupings. The synergistic effect of hs-CRP and LVH on CI was also analyzed using the EpiR package.
Results:
Among HD patients, 122 (52.59%) patients had CI. Multifactorial logistic regression analysis showed that the following factors were associated with an increased risk of CI in HD patients: age (OR = 1.048; 95% CI 1.014-1.083; p = 0.005), LVH (OR = 3.741; 95% CI 1.828-7.657; p < 0.001), and high-risk hs-CRP levels (>3 mg/L; OR = 3.238; 95% CI 1.349-7.768; p = 0.009). In addition, there was a significant synergy between hs-CRP high risk (>3 mg/L) and LVH.
Conclusion:
Age, LVH, and high risk of hs-CRP (>3 mg/L) were independent risk factors for CI in HD patients. Moreover, HD patients with both hs-CRP high risk (>3.0 mg/L) and LVH were at higher risk of developing CI, and lowering hs-CRP levels and preventing LVH may prevent CI.
