目的
2
本研究拟明确血浆纤维蛋白原与定量CT(QCT)测量的体积骨密度及定义的骨质疏松症的相关性,探讨血浆纤维蛋白原在骨质疏松症早期筛查、诊治中的作用。
方法
2
本研究选取2018 年1月至2022年6月在中山大学孙逸仙纪念医院内分泌与代谢病科住院并行腰椎QCT检查的高血压患者进行横断面分析,分析血浆纤维蛋白原与骨质疏松症的相关性,通过受试者工作特征曲线下面积评估血浆纤维蛋白原对骨质疏松症的诊断效能。
结果
2
本研究最终纳入分析的研究对象有441人,年龄为(46.0 ± 14.5)岁,骨质疏松症患病率为6.4%(28/441)。随着血浆纤维蛋白原水平升高,骨质疏松症的患病率显著增加(
P
<
0.000 1);L1和L2的平均骨密度显著降低(
P
<
0.05)。与血浆纤维蛋白原处于第一分位(1.99g/L~2.37g/L)的人群相比较,在校正相关混杂因素(年龄、性别、BMI)后,血浆纤维蛋白原处于第四分位(3.67g/L~4.46g/L)的人群骨质疏松症的患病风险增加了 8.85 倍。
结论
2
本研究发现高血压患者血浆纤维蛋白原水平与骨密度呈负相关,血浆纤维蛋白原水平可作为骨质疏松症的潜在筛查指标,有助于早期诊断和治疗监测。这一发现为骨代谢疾病的研究提供了新的视角,值得深入探究。
Objective
2
To clarify the associations between plasma fibrinogen (Fbg) and volumetric bone mineral density (vBMD) as well as osteoporosis measured by quantitative computed tomography (QCT), and to explore the role of plasma Fbg in early screening and diagnosis of osteoporosis.
Methods
2
Patients with hypertension who were hospitalized in the Department of Endocrinology of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2018 to June 2022 and underwent QCT examinations were included for cross-sectional analysis. The study analyzed the correlation between plasma Fbg and osteoporosis in patients. The diagnostic efficacy of plasma Fbg for osteoporosis was evaluated by the area under the receiver operating characteristic (ROC) curve (AUC).
Results
2
Totally 441 subjects were included in the analysis, with an average age of 46.0±14.5 years and a prevalence of osteoporosis of 6.4% (28/441). As the level of plasma fibrinogen increased, the incidence of osteoporosis significa
ntly increased (
P
<
0.000 1)while the average bone mineral density of L1 and L2 were significantly decreased (
P
<
0.05). Compared with the first quartile of plasma Fbg(1.99g/L -2.37g/L), the risk of osteoporosis in the fourth quartile of plasma Fbg (3.67g/L-4.46g/L) increased by 8.85 times after adjusting for related confounding factors.
Conclusion
2
This study found a negative correlation between plasma fibrinogen levels and bone density in patients with hypertension. Plasma fibrinogen levels may serve as a potential screening indicator for osteoporosis, aiding in early diagnosis and therapeutic monitoring. This discovery offers a new perspective for the study of bone metabolic diseases and warrants further investigation.
