【摘要】 目的 老年综合评估法筛查75岁以上2型糖尿病（type 2 diabetes mellitus，T2DM）合并老年综合征的情况，并观察以甘精胰岛素为基础的治疗方法对老年综合征、血糖、低血糖事件、治疗满意度等的影响。 方法 应用老年综合评估中的日常生活能力、工具性日程生活能力、简易智能量表、老年抑郁量表、微型营养评定法，分别评估2005年12月—2009年12月老年门诊及病房住院的日常生活能力、认知功能状态、情绪障碍和营养状态，对其合并功能障碍、痴呆、抑郁、营养障碍、伤害性跌倒等老年综合征的患病情况进行横断面调查；筛选至少合并一种老年综合征和一个其他合并疾病，血糖控制差、预期寿命有限的患者进行以甘精胰岛素为基础的降糖治疗，采用自身前后对照的方法了解对糖化血红蛋白（hemoglobin A1c， HbA1c）、低血糖事件、治疗满意度的影响，并观察甘精胰岛素治疗方案对上述老年综合征的影响。 结果 132例老年门诊及病房住院的75岁以上T2DM患者功能障碍者高达50.0%（66例），罹患包括轻度认知功能障碍在内的痴呆比例为39.4%（52例）；合并抑郁症28.0%（37例）；营养失衡30.0%（39例）。33例患者符合甘精胰岛素治疗纳入标准，经过2年的随访发现，以甘精胰岛素为基础的治疗方案在适当降低HbA1c水平时，不增加老年综合征的患病率，但可以减少胰岛素多次皮下注射的次数，降低低血糖事件发生次数（由1.58次/例降为0.81次/例），提高患者治疗满意度。 结论 75岁以上T2DM患者合并老年综合征的比例高，老年综合评估能及时发现老年综合征；以甘精胰岛素为基础的治疗方案不增加老年综合征的发生，并能显著降低低血糖事件数、改善营养状态、提高患者对治疗的满意度。【Abstract】 Objective To screen geriatric syndrome in patients older than 75 years with type 2 diabetes mellitus (T2DM) by the method of comprehensive geriatric assessment, and observe the impact of glargin-based therapy on geriatric syndrome, blood glucose level, the event of hypoglycemia and treatment satisfaction degree in patients older than 75 years with T2DM who suffered at least one kind of Geriatric syndromes. Methods From December 2005 to December 2009, activity of daily living (ADL), instrument activity of daily living (IADL), mini-mental state examination, geriatric depression scale and mini-nutritional assessment in comprehensive geriatric assessment were used to assess daily living ability, cognitive function status, emotional disorder and nutritional status of out/in-patients older than 75 years with T2DM in the Department of Geriatrics. Cross-sectional study was carried out to investigate geriatric syndromes such as combined functional disorder, dementia, depression, nutritional disorder and impairment falls in those patients, and patients with T2DM combined with at least one kind of geriatric syndrome and another kind of combined disease were screened out. A glargin-based anti-hyperglycemic therapy was carried out for those patients with poor blood glucose control limited remaining life time. The effects of this therapy on hemoglobin A1c (HbA1c), the event of hypoglycemia and treatment satisfaction degree of the patients were studied through a self-comparison method. Then, its effect on the above-mentioned geriatric syndromes was observed. Results Among all the 132 out/in patients older than 75 years with T2DM, the prevalence rates of functional disorder (including ADL and IADL), dementia including mild cognitive disorder, depression, and malnutrition were respectively 50.0% (66), 39.4% (52), 28.0% (37), and 30.0% (39). Only 33 patients met the criteria of glargin-based treatment. After 2 years of follow-up, we found that the glargin-based treatment could properly decrease the level of HbA1c without increasing the prevalence rate of geriatric syndrome. Moreover, it could reduce the frequency of insulin injection and the events of hypoglycemia, and treatment satisfaction degree was also significantly improved. Conclusions Geriatric syndrome has a relatively high prevalence rate in patients older than 75 years with T2DM. Comprehensive geriatric assessment is beneficial in finding out the geriatric syndrome, and glargin-based hypoglycemic therapy can significantly reduce the events of hypoglycemia, improve nutritional status, and increase treatment satisfaction degree without increasing the rate of geriatric syndrome .
ObjectiveTo explore the relationship between glycated hemoglobin (HbA1c) level and blood glucose fluctuations after coronary artery bypass grafting (CABG) and adverse events in non-diabetic patients, thus providing theoretical support for intensive preoperative blood glucose management in patients undergoing CABG surgery.MethodsA total of 304 patients undergoing CABG with or without valvular surgery from October 2013 to December 2017 were enrolled in this prospective, single-center, observational cohort study. We classified them into two different groups which were a low-level group and a high-level group according to the HbA1c level. There were 102 males and 37 females, aged 36–85 (61.5±9.5) years in the low-level group, and 118 males and 47 females aged 34–85 (63.1±9.4) years in the high-level group. The main results were different in hospital mortality and perioperative complications including in-hospital death, myocardial infarction, sternal incision infection, new stroke, new-onset renal failure and multiple organ failure. To assess the effects of confounding factors, multivariate logistic regression analysis was used.Results Postoperative blood glucose fluctuation was more pronounced in the high-level group than that in the low-level group before admission [0.8 (0.6, 1.2) mmol/L vs. 1.0 (0.8, 1.8) mmol/L, P<0.01]. This study also suggested that the incidence of major adverse events was significantly lower in the low-level group compared with the high-level group (P=0.001). Multivariate logistic regression analyses to correct the influence of other confounding factors showed that HbA1c (OR=2.773, P=0.002) and postoperative blood glucose fluctuations (OR=3.091, P<0.001) could still predict the occurrence of postoperative adverse events.ConclusionHbA1c on admission can effectively predict blood glucose fluctuations in 24 hours after surgery. Secondly, HbA1c on admission and postoperative blood glucose fluctuations can further predict postoperative adverse events. It is suggested that we control the patient's preoperative HbA1c at a low level, which is beneficial to control postoperative blood glucose fluctuation and postoperative adverse events.
