Insights
Interleukin-34 (IL-34) levels are elevated in coronary artery disease (CAD) patients and correlate with high-sensitivity C-reactive protein (hs-CRP). IL-34 may serve as an independent predictor for CAD.
Area of Science:
- Cardiology
- Immunology
- Biochemistry
Background:
- Coronary artery disease (CAD) is a significant global health concern.
- Interleukin-34 (IL-34) is a proinflammatory cytokine implicated in various inflammatory conditions.
Purpose of the Study:
- To investigate serum levels of IL-34 in patients with CAD.
- To determine the correlation between IL-34 and hs-CRP in CAD patients.
- To assess IL-34 as a potential independent predictor of CAD.
Main Methods:
- 91 patients underwent coronary angiography and were categorized into CAD (stenosis ≥ 50%) and control (< 50%) groups.
- Serum IL-34 and hs-CRP levels were measured using standardized assays.
- Multiple regression analysis was employed to identify independent predictors.
Main Results:
- CAD patients exhibited significantly higher serum IL-34 (191.3 ± 17.9 pg/ml) and hs-CRP (3.08 ± 1.81 mg/ml) levels compared to controls.
- A significant positive correlation was observed between IL-34 and hs-CRP in the CAD group.
- IL-34 (OR 2.073) and hs-CRP (OR 1.878) were identified as independent predictors of CAD.
Conclusions:
- Serum IL-34 levels are significantly elevated in patients diagnosed with coronary artery disease.
- IL-34 levels show a positive correlation with hs-CRP, a known inflammation marker.
- These findings suggest IL-34 may represent a novel independent biomarker for CAD.
Objective:
This study investigated levels of interleukin (IL)-34, a proinflammatory cytokine, in patients with coronary artery disease (CAD).
Methods:
Following coronary artery angiography, 91 patients with CAD (including stable and unstable angina pectoris) were divided into two groups, the CAD group (coronary artery stenosis ≥ 50%) and the control group (coronary artery stenosis < 50%). Serum levels of factors including IL-34 and high sensitivity C-reactive protein (hs-CRP) were measured.
Results:
IL-34 and hs-CRP levels were significantly higher in the CAD group than in the control group (191.3 ± 17.9 pg/ml versus 125.4 ± 14.8 pg/ml and 3.08 ± 1.81 mg/ml versus 1.42 ± 1.01 mg/ml, respectively), with a significantly positive correlation between IL-34 and hs-CRP levels in the CAD group. Multiple regression analysis showed that IL-34 and hs-CRP levels were independent predictors of CAD (IL-34: odds ratio [OR] 2.073, 95% confidence intervals (CI) 1.419, 2.672; hs-CRP: OR 1.878, 95% CI 1.172, 2.531).
Conclusions:
IL-34 levels were significantly increased in patients with CAD, and positively correlated with hs-CRP levels, suggesting that IL-34 may be an independent predictor of CAD.
