2型糖尿病患者扫描式葡萄糖监测系统指标与尿白蛋白/肌酐比值的相关性研究

背景 随着血糖监测技术的发展，近些年来人们开始使用扫描式葡萄糖监测系统（FGMS）"全景式"地观察2型糖尿病（T2DM）患者的血糖水平，明确FGMS指标与T2DM并发症之间的关系有助于提高其临床应用价值，但目前相关研究较少。 目的 探究佩戴FGMS的T2DM患者葡萄糖在目标范围内时间（TIR）等指标与尿白蛋白/肌酐比值（UACR）的相关性。 方法 选取2019年1月至2021年10月于北京大学人民医院老年科就诊并佩戴FGMS的T2DM患者79例，以尿液检查中UACR是否<30 mg/g将患者分为无白蛋白尿组（n=50）和白蛋白尿组（n=29）。比较两组患者的临床特征、实验室检查指标及FGMS指标等。采用Pearson相关、Spearman秩相关分析探讨TIR、高血糖时间（TAR）与糖化血红蛋白（HbA1c）的相关性。分别采用Pearson相关、Spearman秩相关、偏相关分析探讨FGMS指标与lnUACR的相关性。使用多因素Logistic回归分析探究T2DM患者发生白蛋白尿的影响因素，采用受试者工作特征（ROC）曲线评估TIR对白蛋白尿的预测价值。 结果 白蛋白尿组T2DM病程长于无白蛋白尿组，三酰甘油（TG）、HbA1c、平均血糖（MBG）、TAR、平均血糖标准差（SDBG）、最大葡萄糖波动幅度（LAGE）、平均葡萄糖波动幅度（MAGE）、连续每隔2 h血糖净作用（CONGA2）高于无白蛋白尿组，TIR低于无白蛋白尿组（P<0.05）。Pearson相关、Spearman秩相关分析结果显示，TIR与HbA1c呈负相关（P<0.001），TAR与HbA1c呈正相关（P<0.001）。Pearson相关、Spearman秩相关、偏相关分析结果均表明，TIR与lnUACR呈负相关（P<0.001），MBG、TAR、SDBG、LAGE、MAGE、CONGA2与lnUACR呈正相关（P<0.001）。多因素Logistic回归分析结果显示，TIR>70%〔OR=0.038，95%CI（0.003，0.467）〕是T2DM患者出现白蛋白尿的保护因素（P<0.05），TAR升高〔OR=1.046，95%CI（1.000，1.094）〕是T2DM患者出现白蛋白尿的危险因素（P<0.05）。TIR预测T2DM患者出现白蛋白尿的ROC曲线下面积（AUC）为0.784〔95%CI（0.674，0.894）〕（P=0.003），灵敏度为78%，特异度为83%，最佳切点为69.71%。 结论 在FGMS指标中，TIR>70%是T2DM患者出现白蛋白尿的保护因素，TAR升高是T2DM患者出现白蛋白尿的危险因素。同时，SDBG、LAGE、MAGE、CONGA2等多种反映血糖波动的指标也与UACR密切相关。对TIR水平较低及TAR、SDBG、LAGE、MAGE、CONGA2水平较高的T2DM患者进行FGMS筛查有助于早期识别及预防白蛋白尿的发生、发展。     

The effect of ChAdOx1 nCov-19 vaccine on arterial thrombosis development and platelet aggregation in female rats

ChAdOx1 nCoV-19 adenoviral vector vaccine (ChAd) against coronavirus disease 2019 has been associated with vaccine-induced thrombosis and thrombocytopenia (VITT), especially in young women who have presented with unusual localized thrombosis after receiving the vaccine. The pathogenesis of VITT remains incompletely understood. We tried to provide new insights into mechanisms underlying this phenomenon in the model of arterial thrombosis electrically induced in the carotid artery of female rats. At 28 days post-vaccination, ChAd induced SARS-CoV-2-specific neutralizing antibody responses in all animals. The analysis of the blood vessel/thrombus area showed slight luminal narrowing of the carotid artery with extravasation of blood in vaccinated rats. These small changes were not accompanied by differences in thrombus weight and composition. The vaccinated animals presented a slight increase (by around 14–24%) in platelet aggregation. ChAd did not significantly affect blood coagulation, platelet counts, and their activation markers. Unaffected thrombus formation, the lack of thrombocytopenia and all the measured blood and hemostasis parameters that predominantly stayed unchanged, indicate that the ChAd does not increase the risk of arterial thrombosis development in female rats.

Maximizing Breast Cancer Therapy with Awareness of Potential Treatment-Related Blood Disorders

In this review we summarize the impact of the various modalities of breast cancer therapy coupled with intrinsic patient factors on incidence of subsequent treatment-induced myelodysplasia and acute myelogenous leukemia (t-MDS/AML). It is clear that risk is increased for patients treated with radiation and chemotherapy at younger ages. Radiation is associated with modest risk, whereas chemotherapy, particularly the combination of an alkylating agent and an anthracycline, carries higher risk and radiation and chemotherapy combined increase the risk markedly. Recently, treatment with granulocyte colony-stimulating factor (G-CSF), but not pegylated G-CSF, has been identified as a factor associated with increased t-MDS/AML risk. Two newly identified associations may link homologous DNA repair gene deficiency and poly (ADP-ribose) polymerase inhibitor treatment to increased t-MDS/AML risk. When predisposing factors, such as young age, are combined with an increasing number of potentially leukemogenic treatments that may not confer large risk singly, the risk of t-MDS/AML appears to increase. Patient and treatment factors combine to form a biological cascade that can trigger a myelodysplastic event. Patients with breast cancer are often exposed to many of these risk factors in the course of their treatment, and triple-negative patients, who are often younger and/or BRCA positive, are often exposed to all of them. It is important going forward to identify effective therapies without these adverse associated effects and choose existing therapies that minimize the risk of t-MDS/AML without sacrificing therapeutic gain.

Implications for Practice

Breast cancer is far more curable than in the past but requires multimodality treatment. Great care must be taken to use the least leukemogenic treatment programs that do not sacrifice efficacy. Elimination of radiation and anthracycline/alkylating agent regimens will be helpful where possible, particularly in younger patients and possibly those with homologous repair deficiency (HRD). Use of colony-stimulating factors should be limited to those who truly require them for safe chemotherapy administration. Further study of a possible leukemogenic association with HRD and the various forms of colony-stimulating factors is badly needed.
