Objective: To compare the efficacy of preprotein convertase subtilisin lysozyme 9 (PCSK9) inhibitors with statins in patients with type 2 diabetes mellitus (T2DM). Methods: A total of 140 patients with T2DM (80 males and 60 females) in the People's Hospital Affiliated to Shandong First Medical University from January 2018 to January 2021 were selected, with a mean age of (55±5) years (41-72 years). The patients were divided into observation group (n=68) and control group (n=72) by the random number table method. Both groups were given conventional treatments such as hypoglycemic drugs, the control group was given statins to regulate lipids, and the observation group was given PCSK9 inhibitors to lower lipids. The differences of low-density lipoprotein cholesterol (LDL-C), interleukin (IL)-1, IL-6, IL-8, IL-10, tumor necrosis factor-α (TNF-α), C-reactive protein (CRP) expression levels and standard-reaching rate of LDL-C between the two groups were compared. The correlation between serum PCSK9 level and fasting plasma glucose (FPG), hemoglobin A1c (HbA1c) and other indicators in T2DM patients was analyzed by Pearson correlation analysis. Results: After treatment, the LDL-C of the observation group was (2.3±0.7) mmol/L, which was lower than that of the control group [(2.7±0.7) mmol/L] (P=0.024); the standard-reaching rate of LDL-C of the observation group was 89.7% (61/68), which was higher than that of the control group [68.1% (49/72)] (P=0.002); the levels of IL-1, IL-6, TNF-, CRP, IL-10 and IL-8 in the observation group after treatment were (27.6±6.6) ng/L, (36.7±6.9) ng/L, (40.1±8.9) ng/L, (7.8±1.8) ng/L, (19.2±3.3) ng/L, (13.7±3.3) ng/L, respectively, which were lower than those in the control group [(30.6±7.9) ng/L, (40.1±7.3) ng/L, (43.4±9.2) ng/L, (10.4±2.5) ng/L, (30.7±3.7) ng/L, (26.8±3.4) ng/L, respectively] (all P<0.05). After treatment, the PCSK9 level in the observation group was (74±13) μg/L, which was lower than that in the control group [(97±14) μg/L] (P<0.001). The level of PCSK9 in T2DM patients was positively correlated with LDL-C, IL-1, IL-6 and TNF-α (r=0.390, 0.433, 0.398 and 0.562, all P<0.05). Conclusion: PCSK9 inhibitors have better lipid-regulating effects in patients with T2DM and can improve the level of inflammation at the same time.
目的： 比较前蛋白转化酶枯草溶菌酶9（PCSK9）抑制剂与他汀类药物对2型糖尿病（T2DM）患者血脂异常的疗效。 方法： 选取2018年1月至2021年1月山东第一医科大学附属人民医院血脂异常的T2DM患者140例，其中男80例，女60例，年龄41~72（55±5）岁。采用随机数字表法分为观察组（n=68）和对照组（n=72）。两组患者均给予降糖等常规治疗，其中对照组给予他汀类药物调脂，观察组给予PCSK9抑制剂调脂。比较两组患者治疗前后低密度脂蛋白胆固醇（LDL-C）、白细胞介素（IL）-1、IL-6、IL-8、IL-10、肿瘤坏死因子α（TNF-α）、C反应蛋白（CRP）表达水平的差异以及LDL-C达标率的差异。T2DM患者血清PCSK9水平与空腹血糖（FPG）、糖化血红蛋白（HbA1c）等指标的相关性采用Pearson相关分析。 结果： 观察组治疗后LDL-C为（2.3±0.7）mmol/L，低于对照组的（2.7±0.7）mmol/L（P=0.024）；观察组LDL-C达标率为89.7%（61/68），高于对照组的68.1%（49/72）（P=0.002）；观察组治疗后IL-1、IL-6、TNF-α、CRP、IL-10和IL-8水平分别为（27.6±6.6）、（36.7±6.9）、（40.1±8.9）、（7.8±1.8）、（19.2±3.3）、（13.7±3.3）ng/L，均低于对照组的（30.6±7.9）、（40.1±7.3）、（43.4±9.2）、（10.4±2.5）、（30.7±3.7）、（26.8±3.4）ng/L（均P<0.05）。观察组治疗后PCSK9水平为（74±13）μg/L，低于对照组的（97±14）μg/L（P<0.001）。T2DM患者PCSK9水平与LDL-C、IL-1、IL-6和TNF-α呈正相关（r=0.390、0.433、0.398、0.562，均P<0.05）。 结论： PCSK9抑制剂在T2DM患者中调脂作用较好，同时可改善炎症水平。.
