Abstract:

Objective To investigate the clinical diagnosis and predictive value of blood lipid index in brittle fracture elderly patients with osteoporosis. Methods Totally,196 patients with osteoporosis and 129 patients with brittle fracture were enrolled. Low-density lipoprotein cholesterol(LDL-C),triglyceride(TG),small and dense low-density lipoprotein cholesterol(sd-LDL-C),high-density lipoprotein cholesterol(HDL-C),apolipoprotein(apo) A,apo B,apo E,total cholesterol(TC) and lipoprotein a [Lp(a)] were determined. Binary Logistic regression analysis was used to adjust for confounding factors to evaluate the risk factors of brittle fracture in elderly patients with osteoporosis. Results The levels of LDL-C,TG,TC and apo A in brittle fracture group were higher than those in osteoporosis group,while the levels of HDL-C and sd-LDL-C were lower than those in osteoporosis group(P<0.05). There was no statistical significance in apo B,apo E and Lp(a)levels between the 2 groups(P>0.05). Multivariate binary Logistic regression analysis showed that increased LDL-C,TG,TC,apo A and decreased HDL-C were risk factors for brittle fracture in osteoporosis patients [odds ratios(OR) were 1.473,1.543,1.745,1.535 and 0.177,95% confidence intervals(CI) were 1.094-1.985,1.125-2.114,1.381-2.206,1.098-1.848 and 0.090-0.349,respectively]. Conclusions Dyslipidemia is related with brittle fracture in elderly patients with osteoporosis.
