The effect of depression on quality of life of patients with type II diabetes mellitus

Diabetes mellitus (DM) is a frequently encountered metabolic disease with chronic features and involves numerous complications throughout its course, which causes severe restriction and disability in an individual's life. It has been reported that the incidence of depression is higher in diabetic patients and that diabetes is one of the risk factors in the development of depression. It has also been reported that co-morbid psychiatric disorders cause further deterioration in the quality of life in diabetic patients. The aim of this study was to investigate the effects of depression on the quality of life in type II DM patients. Sixty patients (30 females and 30 males) with current major depressive episode diagnosed according to DSM-IV criteria, and 48 type II DM patients (30 females and 18 males) without a major depressive episode (non-depressed group) were included in the study. All patients were evaluated with a semi-structured interview form to assess the clinical features of DM, Hamilton Rating Scale for Anxiety (HRSA), Hamilton Rating Scale for Depression (HRSD), and the Turkish version of The World Health Organization Quality of Life Assessment-Brief (WHOQOL-BREF). The HRSD and HRSA scores in the depressed group were 24.87+/-4.83 and 21.07+/-5.44, respectively, whereas those in the non-depressed group were 7.83+/-3.92 and 6.88+/-3.43, respectively. The physical health, psychological health, social relationship, environmental and social pressure domain, general health-related quality of life, overall quality of life, and WHOQOL-BREF total scores were found significantly lower in the depressed group than the non-depressed group. There were significant negative correlations between HRSD and HRSA scores and physical health, psychological health, social relationship, environmental and social pressure domain, general health-related quality of life, overall quality of life, and WHOQOL-BREF total scores. Furthermore, there were significant negative correlations between the HbA1c level and physical health, social relationship, environmental domain, social pressure domain, general health-related quality of life, overall quality of life, and WHOQOL-BREF total scores. However, there was a significant positive correlation between the level of education and physical health, psychological health, social relationship, environmental social pressure domain, overall quality of life, and WHOQOL-BREF total scores. There were significant negative correlations between social relationship domain score, and age and duration of illness. Our study demonstrates that the presence of depression in type II DM further deteriorates the quality of life of the patients. Since treating depression would have a beneficial effect on the quality of life, clinicians should carefully assess for depression associated with type II DM.     

The effect of sleep impairment on gestational diabetes mellitus: a systematic review and meta-analysis of cohort studies

ObjectiveThis systematic review and meta-analysis evaluated the influence of sleep duration or impairment (poor sleep quality, snoring, and obstructive sleep apnea [OSA]) on gestational diabetes mellitus (GDM) risk.MethodsPubMed, Embase, EBSCO, and WOS databases were searched up to March 4th, 2019. Cohort studies were included and relative risk (RR) with 95% confidence interval (CI) were used as the measure of effects. Heterogeneity was assessed by the Chi-squared and I² tests. Subgroup analyses, sensitivity analysis, and dose-response analysis were performed. The overall quality of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.ResultsA total of 16 studies with 2,551,017 pregnant women and 142,103 GDM cases were included in this study. Both short and long sleep duration were associated with increased risk of GDM. There was a U-shaped relationship between sleep duration and GDM risk (P_{-nonlinearity} < 0.001), and pregnant women with 8 h of sleep presented lower GDM risk. Poor sleep quality, snoring and OSA also increased the subsequent risk of GDM.ConclusionsPregnant women should be made aware of the benefits of proper sleep, and those with poor sleep quality, snoring, and OSA should be screened for GDM.     

Myasthenia gravis: sleep quality, quality of life, and disease severity

Introduction: There is much research on quality of life in myasthenia gravis (MG), and its relationship to disease severity is well‐established. However, evidence regarding sleep disturbance in MG is inconclusive. Methods: To evaluate sleep and quality of life among clinically stable MG patients, 54 subjects were investigated by means of the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS) and 15‐Item‐Quality‐Of‐Life Instrument for MG (MG‐QOL15). Results: A pathological PSQI score, which was observed in 59% of patients, was increased in subjects with active disease compared with patients in clinical remission [odds ratio = 4.3; confidence interval 95% (1.0–17.6); P = 0.04]. We found a relationship between PSQI and MG‐QOL15 scores in patients with clinically active disease (r = 0.62; P < 0.001). Conclusions: Our study highlights the high prevalence of sleep disturbance among MG patients. Disease severity may be considered to be a MG‐specific risk factor for patient‐reported sleep disturbance. The MG‐QOL15 and PSQI should be used to estimate the impact of the disease on sleep and quality of life. Muscle Nerve 46: 174–180, 2012     

Health-related quality of life in type 1 diabetic patients and influence of peripheral nerve involvement

We examined the relationships between diabetic peripheral nerve involvement and patients' own perception of quality of life in a multidimensional study based on outcome research recommendations. The study enrolled 50 consecutive outpatients with type 1 diabetes mellitus (23 men, 27 women; mean age, 40.1 years). The patients were evaluated with validated clinical tests (e. g. Semmes-Weinstein, vibration perception threshold, muscle strength), neurophysiological tests (sural, peroneal and ulnar nerves) and patient-oriented (SF-36 and NASS) questionnaires. Patient-oriented physical scores were significantly related with: (1) neurophysiological findings of the lower limbs; (2) conventional measurements of sensitivity. Conversely, patient-oriented mental scores were not related with these findings. The patient-oriented questionnaires provided an important perspective of the severity of the disease, often closely related with the biological parameters. They offered new interpretations to conventional biological measurements. In particular, the peripheral nerve picture was strictly related to the physical aspects of the patients' quality of life, and not with the mental aspects.

伴有抑郁的2型糖尿病患者生活质量及家庭功能

目的:探讨伴有抑郁的2型糖尿病患者生活质量及家庭功能特征。方法:采用生活质量量表(QLESQ)、家庭功能量表(FAD)以及贝克抑郁量表(BDI)对50例2型糖尿病患者(糖尿病组)及50名正常人(正常对照组)进行调查。结果:38%(19/50例)的2型糖尿病患者伴有抑郁。糖尿病组FAD评分中情感卷入及行为控制维度在不健康家庭功能范围内;QLESQ总分(32.49±5.86)分明显低于正常对照组(37.76±5.38)分(P<0.01)。糖尿病组FAD的问题解决、角色和情感卷入维度与抑郁症状呈正相关(r分别=0.426、0.339、0.454,P<0.05或P<0.01);QLESQ总分与家庭功能的角色和行为控制维度呈负相关(r分别=-0.292、-0.344,P<0.01)。结论:伴发抑郁的2型糖尿病患者生活质量差且家庭功能有缺陷。     

Health-related quality of life and health locus of control beliefs among HIV-infected treated patients

Obsjective:This study examined the relations between health locus of control (HLOC) beliefs and health-related quality of life (HRQL) in 302 HIV-infected patients enrolled in a French cohort, 44 months (M44) after they began highly active antiretroviral therapy (HAART). Methods: HLOC beliefs were measured with the Multidimensional Health Locus of Control (MHLOC) scale and HRQL, with the Medical Outcome Study Short-Form Health Survey (MOS-SF-36). Results: Internal HLOC beliefs at the initiation of treatment were associated with both physical HRQL in multivariate analysis, while chance HLOC beliefs on beginning HAART were associated with mental HRQL at M44. Conclusion: These findings suggest the importance of considering the psychological characteristics and psychosocial beliefs of patients at the initiation of ARV treatment to optimise the long-term HRQL of HIV-infected patient and to develop adaptive intervention on coping strategies.     

Alexithymia as a risk factor for type 2 diabetes mellitus in the metabolic syndrome: a cross-sectional study

Alexithymia is a clinical trait consisting of diminished introspective and interoceptive capacities that has been shown to implicate elevated autonomic outflow and to bias for hypertension. To estimate relative risk associated with alexithymia in the metabolic syndrome (MetS), we conducted a cross-sectional analysis of patients with manifest type 2 diabetes mellitus (T2DM) or familial diabetes risk (N=101; 67 females; age 45.6±13.96) in a nationwide sampled treatment cohort for MetS in the Ukrainian governmental health care system. Laboratory data of single components of the MetS according to International Diabetes Federation Consensus were dependent measures in multivariable regression models with self-reported alexithymia severity (TAS-20) and socio-demographic data. TAS-20 as the sole surviving psychometric predictor for T2DM in the simplest regression equation provided the best model fit: OR 1.073, Z=19.04, (95%CIs 1.065–1.081). For microalbuminuria, the best fitting model was OR 1.030, Z=3.49 (95%CIs 1.013–1.048). TAS-20 predicted also triglyceride level at Wald-χ²=1299.27, Z=36.05 (95%CIs 0.052–0.058) and blood pressure maximum at Wald-χ²=2309.05, Z=48.05 (95%CIs 2.402–2.606). Our results show that alexithymia severity contributes to MetS by covarying with several of its single components, and that it may be a substantial concurrent indicator of T2DM and cardiovascular risks in MetS.     

Health-related quality of life of people with epilepsy compared with a general reference population: a Tunisian study

PURPOSE: The goal of the study was to assess the health-related quality of life (HRQOL) of persons with epilepsy (PWE) by using the short form survey 36 (SF-36), to compare it with that of a control group and to detect factors influencing it. METHODS: We collected clinical and demographic data and information on health status by using the Arabic translation of the SF-36 questionnaire from two groups: (a) 120 PWE consulting our outpatient clinic during a period of 4 months, and (b) 110 Tunisian citizens, representative of the Tunisian general population, as a control group. RESULTS: The mean age of PWE group was 32.74 years, and 45.5% were men. Idiopathic generalized epilepsies were observed in 44.5% of cases, and symptomatic partial epilepsies, in 30%. The most commonly prescribed drug was sodium valproate (VPA). For the SF-36, PWE had lower scores than the control group for only three subscales: general health perception, mental health, and social functioning. Seizure frequency, time since last seizure, and the antiepileptic drug (AED) side effects were the most important variables influencing the HRQOL among PWE. Seizure-free adults have HRQOL levels comparable to those of the control group. Sociodemographic variables had no influence on the SF-36 subscales. CONCLUSIONS: HRQOL is impaired in Tunisian PWE. The influencing factors identified in this study differ from the previously published data. Several possible reasons such as family support and cultural and religious beliefs are proposed to explain these cross-cultural differences. A larger study should be conducted to verify such findings.     

Association between perceived environmental pollution and poor sleep quality: results from nationwide general population sample of 162,797 people

Objective/BackgroundPerceived environmental pollution may play a significant role in understanding environmentally induced health-related symptoms. This study aimed to determine whether perceived environmental pollution is associated with poor sleep quality.MethodsWe conducted a cross-sectional study using data from a nationwide sample of 162,797 individuals aged ≥19 years from the 2018 Korea Community Health Survey. The Pittsburgh Sleep Quality Index was used for assessing sleep quality. Five types of perceived environmental pollutants involving air, water, soil, noise, and green space were assessed. We investigate the association between perceived environmental pollution and poor sleep quality. We also investigated whether an increasing number of perceived environmental pollutants magnified the odds of poor sleep quality.ResultsThe prevalence of poor sleep quality was 42.7% (n = 69,554), and 15.6%, 10.1%, 11.9%, 23.0%, and 11.5% reported perceived environmental pollution concerning air, water, soil, noise, and green space, respectively. A perception of air, soil, or noise pollution was significantly associated with poor sleep quality. In addition, those perceiving a greater number of environmental pollutants had significantly higher odds of poor sleep quality. Notably, this association was magnified in individuals living in rural areas.ConclusionsPerceived environmental pollution was significantly associated with poor sleep quality. Our results suggest that a more comprehensive exposure to environmental pollution may not only have a worse effect on health outcomes including sleep quality.     

Disease-specific quality-of-life measures as predictors of mortality in individuals living with type 2 diabetes

Objective

The aim of this study was to examine whether disease-specific quality-of-life measures are independent predictors of mortality in patients with type 2 diabetes.

Methods

A cohort of 420 patients with type 2 diabetes was recruited from the outpatient clinic of a medical center. At baseline, the disease-specific measure of the Diabetes Impact Measurement Scales (DIMS) and clinical and biological marker variables were measured. The DIMS domains included symptoms, diabetes-related morale, social role fulfillment, and well-being. Complications consisted of stroke, heart disease, visual impairment, amputations, kidney disease, cognitive impairment, and incontinence. Mortality data were collected from the national mortality register using personal identification numbers. Multivariate Cox proportional hazards models were used.

Results

The overall mortality rate was 10.9%. The DIMS scales of symptoms and well-being and the total score were significantly associated with mortality, independent of age, gender, glucose control, and complications. When the scales of the DIMS were simultaneously considered, only symptom and social role fulfillment of the DIMS exerted a significant effect on mortality. Patients in the categories of the second and third quartiles (worse status) had significantly increased risk compared with those in the category of the fourth quartile (best status) [for the symptom scale: RR=13.10, 95% confidence interval (CI)=2.75-62.50 and RR=5.49, 95% CI=1.50-20.09, respectively; for the social role fulfillment scale: RR=6.18, 95% CI=1.10-34.87 and RR=6.53, 95% CI=1.40-30.57, respectively].

Conclusion

Our data suggest that the unique contribution of health-related quality of life to mortality was independent of objective health measures, such as glucose control and complications.     

Short sleep duration is associated with B-type natriuretic peptide levels and predicts the death of Japanese patients with type 2 diabetes

ObjectiveTo investigate the associations of sleep duration with all-cause mortality, glycemic control, and other clinical parameters of patients with type 2 diabetes.MethodsFrom April 2013 to December 2015, we conducted a retrospective cohort study. Study participants were divided into three groups according to their sleep duration. Multiple regression analysis and Cox proportional hazards analysis were performed to assess the independent associations of sleep duration with clinical parameters and all-cause mortality.ResultsWe enrolled 1233 patients who were then followed for 860 ± 264 days. During the follow-up period, 20 patients (1.6%) died. Sleep duration inversely associated with plasma B-type natriuretic peptide levels (β = −0.203, p = 0.012) in short (<7 h) sleepers, whereas it was positively associated with hemoglobin A1c levels (β = 0.156, p = 0.021) in long (≥9 h) sleepers. Moreover, Cox proportional hazard analysis revealed that short sleep duration was a significant predictor of all-cause mortality (hazard ratio = 0.473; confidence interval 0.248–0.905, p = 0.024).ConclusionShort sleep duration may serve as a prognostic indicator of mortality in Japanese patients with type 2 diabetes and may increase cardiovascular stress. Adequate sleep is essential for the management of type 2 diabetes.     

Effect of valsartan on monocyte/endothelial cell activation markers and adiponectin in hypertensive patients with type 2 diabetes mellitus

Angiotensin II receptor blockade has been shown to have a beneficial effect on the angiopathies of hypertension and hyperglycemia in patients with type 2 diabetes. However, the effect of angiotensin II receptor blockade on monocyte and endothelial cell adhesion markers in type 2 diabetes is poorly understood. We investigated the effects of valsartan on these markers in 53 hypertensive patients with and without type 2 diabetes mellitus. Levels of monocyte activation markers (soluble CD14: 2.1+/-0.9 vs. 3.3+/-1.4 mug/ml, p<0.01; monocyte chemotactic peptide: 392+/-94 vs. 489+/-114 pg/ml, p<0.05; and monocyte-derived microparticles: 264+/-98 vs. 511+/-128/muL, p<0.01) and endothelial cell activation markers (soluble E-selectin: 41+/-11 vs. 61+/-20 ng/ml, p<0.001; and soluble vascular cell adhesion molecule-1: 478+/-82 vs. 584+/-101 ng/ml, p<0.01) were significantly increased in hypertensive patients with type 2 diabetes compared to normotensive controls. In addition, the concentrations of adiponectin were significantly decreased in patients with type 2 diabetes (8.1+/-3.1 vs. 5.2+/-2.5 mug/ml, p<0.01). Regardless of the presence of diabetic complications, both systolic and diastolic blood pressures significantly decreased after valsartan administration (valsartan 80 mg/day for 8 weeks). Monocyte and endothelial cell activation markers were decreased significantly in patients with type 2 diabetes after valsartan treatment, but not in non-type 2 diabetic patients. In addition, valsartan alleviated hypoadiponectinemia in hypertensive patients with diabetes (before vs. after: 5.2+/-2.5 vs. 7.6+/-2.7 mug/ml, p<0.001) but did not increase adiponectin levels in the non-diabetic hypertensive group, for which the average adiponectin level was normal prior to treatment. These results suggest angiotensin II receptor blockade (valsartan) may be beneficial as an anti-atherosclerotic therapy in patients with type 2 diabetes in addition to its anti-hypertensive action.     

Factors influencing quality of life in multiple sclerosis patients: disability, depressive mood, fatigue and sleep quality

OBJECTIVES: In a series of 504 patients with multiple sclerosis (MS), quality of life (QOL) and its main clinical and demographic determinants were assessed in comparison with healthy individuals. MATERIALS AND METHODS: A postal questionnaire with self-completed measures of disability (Expanded Disability Status Scale, EDSS), QOL (Quality of Life Index, QLI), depressive mood (Self-rating Depression Scale, SDS), fatigue severity (Fatigue Severity Scale, FSS) and sleep quality (Pittsburgh Sleep Quality Index, PSQI) was sent to this sample of MS patients. RESULTS: Most patients were severely disabled; almost half were mildly to severely depressed, suffering from reduced sleep quality and/or fatigue. The multiple sclerosis patients had significantly lower QLI scores than healthy controls. EDSS and SDS scores were found to be predictors of global QLI score. Regarding the different QLI domains, mean SDS scores remained predictive for all QLI items, while mean EDSS, PSQI and FSS scores were only predictive for physical domains. CONCLUSION: Our study clearly demonstrates that depressive mood is the main factor influencing QOL. The disability status, fatigue and reduced sleep quality have an impact mainly on physical domains of life quality.     

Correlation between adiponectin and reduction of cell adhesion molecules after pitavastatin treatment in hyperlipidemic patients with type 2 diabetes mellitus

The aim of this study was to determine whether pitavastatin may prevent the progression of atherosclerotic changes in hyperlipidemic patients. Seventy-five hyperlipidemic patients with and without type 2 diabetes were enrolled to receive pitavastatin 2 mg daily. Cell adhesion molecules (sCD40L, sP-selectin, sE-selectin, and sL-selectin), chemokines (MCP-1 and RANTES) and adiponectin were measured at baseline and after 3 and 6 months of pitavastatin treatment. Adiponectin levels prior to pitavastatin treatment in hyperlipidemic patients with and without diabetes were lower than levels in normolipidemic controls. Both total cholesterol and the LDL-cholesterol (LDL-C) decreased significantly after pitavastatin administration. Additionally, hyperlipidemic patients with type 2 diabetes exhibited a significant increase in adiponectin levels after pitavastatin treatment (before vs. 3 months, 6 months, 2.81 ± 0.95 vs. 3.84 ± 0.84 μg/ml (p < 0.01), 4.61 ± 1.15 μg/ml (p < 0.001)). Furthermore, hyperlipidemic diabetics exhibited significant decreases in sE-selectin and sL-selectin levels after 6 months of pitavastatin treatment (sE-selectin, before vs. 6 months, 74 ± 21 vs. 51 ± 10 ng/ml, p < 0.05; sL-selectin, before vs. 6 months, 896 ± 141 vs. 814 ± 129 ng/ml, p < 0.05). In addition, adiponectin showed significant correlation with sE-selectin and sL-selectin in diabetic hyperlipidemia. However, MCP-1, RANTES and sCD40L did not exhibit any differences before or after pitavastatin administration. These results suggest that pitavastatin possesses an adiponectin-dependent anti-atherosclerotic effect in hyperlipidemic patients with type 2 diabetes in addition to its lowering effects on total cholesterol and LDL-C.     

The associations of anxiety, depression and personal illness representations with glycaemic control and health-related quality of life in patients with type 2 diabetes mellitus

OBJECTIVE: This study examined the interrelationships of anxiety, depression and personal illness representations with glycaemic control and health-related quality of life in adults with Type 2 diabetes. METHODS: One hundred eighty-four consecutive patients with Type 2 diabetes mellitus completed the Illness Perception Questionnaire (IPQ), the Well-Being Scale (WBQ) and the Short Form 36 Health Survey Questionnaire (SF-36). Demographic characteristics, details of diabetes status (duration of diabetes, treatments and complications) and glycosylated haemoglobin (HbA1c) were recorded. RESULTS: Depression was correlated with greater perceived symptom load (r = .48, P < .01), worse anticipated consequences (r = -.41, P < .01) and perceived lack of control of diabetes (r = .28, P < .01). After controlling for demographic and illness characteristics, personal illness representations relating to symptom load and anticipated consequences were independently associated with the SF-36 physical functioning score, contributing an additional 15% to the variance. WBQ depression and anxiety scores, along with IPQ control and consequences, were independently associated with SF-36 mental function score, contributing a further 51% to the variance after controlling for demographic and illness details. Neither IPQ nor WBQ scales were associated with HbA1c after controlling for demographic and medical illness details. CONCLUSION: Anxiety, depression and negative beliefs about illness influence physical and mental functioning, but not metabolic control in patients with diabetes.     

Life after surgical resection of a low-grade glioma: A prospective cross-sectional study evaluating health-related quality of life

Health related quality of life (HRQoL) has become an important consideration in LGG patients. We report the largest prospective, longitudinal, cross-sectional cohort study of HRQoL in LGG patients, aiming to identify actionable determinants of HRQoL. Post-operative LGG adults at a large tertiary center underwent HRQoL assessment using the EORTC QLQ-C30 questionnaire administered at follow-up visits and by mail. Scores at 12 month intervals were compared with those from a normative reference population. Spearman’s Rho was used to evaluate correlation of subdomain and symptom scores with global HRQoL and change over time. There were 167 participants and 366 questionnaires analysed. Patients reported reduced global HRQoL at nearly every 12 month interval with significant impairments at 12, 72, 108, and 120+ months postoperative. They also reported a significant impairment in each functional subdomain at 12 months, which persisted to varying degrees over 120 months, as did significant fatigue and insomnia. Role, emotional, and social subdomains, as well as fatigue, were significantly associated with global HRQoL at the first 12 month interval. Overall, there was no significant correlation between time from surgery and global HRQoL or the subdomain functional or symptom sections of the QLQ-C30. LGG patients report considerable, sustained impairments in HRQoL after surgery, particularly in cognitive, emotional, and social function, as well as suffering significant fatigue and insomnia. These are strongly associated with global HRQoL and thus can be considered determinants of global HRQoL that with intervention, may improve HRQoL for our LGG patients.This is the largest prospective longitudinal study of HRQoL in postoperative LGG patients yet reported and is ongoing. It identifies several determinants of impaired HRQoL with available management options and interventions that have the potential to significantly improve HRQoL in these patients.     

Poststroke agitation and aggression and social quality of life: a case control study

Background and objective: Aggression and agitation are common after a stroke. The association between agitation/aggression following stroke and Health-Related Quality of Life (HRQoL) in stroke survivors is unknown. This study aimed to examine the association between agitation/aggression and HRQoL in Chinese stroke survivors.

Methods: Three hundred and twenty-four stroke patients entered this cross-sectional study. Agitation/aggression was assessed using the Chinese version of Neuropsychiatric Inventory (CNPI). HRQoL was measured with the Stroke Specific Quality of Life (SSQoL).

Results: Three months after the index stroke, agitation/aggression was found in 60 (18.5%) patients. In the agitation/aggression group, 44 patients (73.3%) showed passive agitation/aggression, whereas 16 (26.7%) displayed passive and active agitation/aggression. No patients showed only active agitation/aggression. Patients with agitation/aggression were more likely to have history of diabetes and greater severity of depression, as well as lower SSQoL total score and Personality Changes and Social Role scores. Controlling for diabetes and depression severity did not alter the above results. The Energy and Thinking scores of the SSQoL were significantly lower in the passive/active agitation/aggression group relative to the passive agitation/aggression group (adjusted for CNPI aggression/agitation score).

Conclusion: In this study sample, agitation/aggression was preponderantly of the passive type and was associated with poorer HRQoL independently from depression or medical conditions. Patients with both passive and active agitation/aggression had lower Quality of Life (QoL) than patients with only passive agitation/aggression. The causality of the association between low QoL and agitation/aggression needs to be explored in future studies.     

初诊2型糖尿病合并颈动脉斑块患者颈动脉斑块灰阶中位数值预测脑梗死的临床研究

目的 探讨三维超声颈动脉斑块灰阶中位数值(Grayscale median,GSM)对初诊2型糖尿病(Type 2 diabetes mellitus,T2DM)合并颈动脉斑块患者发生脑梗死的预测价值。方法 回顾性分析2017年6月-2020年6月在本院住院治疗的初诊T2DM合并颈动脉斑块患者,根据随访中是否发生脑梗死分为脑梗死组(n=28)和非脑梗死组(n=199); 收集首次住院的临床资料及三维超声颈动脉斑块指标灰阶中位数值(Grayscale median,GSM)、斑块体积(Plaque volume,PV)、斑块厚度(Plaque thickness,PT); 比较2组临床资料及超声指标水平的差异,进一步采用logistic回归分析初诊T2DM患者发生脑梗死的影响因素,采用受试者工作特征(Receiver operating characteristic,ROC)曲线分析不同指标对初诊T2DM患者发生脑梗死的预测效能。结果 脑梗死组合并冠心病的比例(35.71% vs 19.09%)及空腹血糖[(7.37±1.32)vs(6.82±0.85)mmol/L]、餐后2 h血糖[(13.16±3.52)vs(11.97±2.14)mmol/L]、糖化血红蛋白(Glycosylated Hemoglobin, Type A1C,HbA1c)[(7.03±0.98)vs(6.55±0.33)%]、总胆固醇[(5.98±1.13)vs(5.41±0.94)mmol/L]、低密度脂蛋白胆固醇(Low density lipoprotein cholesterol,LDLC)[(3.42±0.65)vs(3.05±0.40)mmol/L]、尿酸[(360.01±76.87)vs(320.15±80.55)mmol/L]水平高于非脑梗死组(P<0.05),颈动脉斑块的GSM[(35.24±6.92)vs(41.93±11.82)]均低于非脑梗死组(P<0.05),颈动脉斑块PT,PV与非脑梗死组比较无明显差异(P>0.05)。LDLC,HbA1c、颈动脉斑块GSM是初诊T2DM患者发生脑梗死的影响因素,比值比分别为36.073、4.205、0.852(P<0.05)且四项指标单独或联合均对初诊T2DM患者发生脑梗死具有预测价值,联合指标的预测效能优于单一指标。结论 初诊T2DM患者颈动脉斑块GSM降低与脑梗死的发病有关,GSM联合实验室指标LDL-C,HbA1c能够进行脑梗死发病的预测。
