BACKGROUND: There is still uncertainty regarding whether diabetes mellitus (DM) can adversely affect patients undergoing carotid endarterectomy (CEA) for carotid stenosis. The aim of the study was to assess the adverse impact of DM on patients with carotid stenosis treated by CEA. METHODS: Eligible studies published between 1 January 2000 and 30 March 2023 were selected from the PubMed, EMBASE, Web of Science, CENTRAL, and ClinicalTrials databases. The short-term and long-term outcomes of major adverse events (MAEs), death, stroke, the composite outcomes of death/stroke, and myocardial infarction (MI) were collected to calculate the pooled effect sizes (ESs), 95% confidence intervals (CIs), and prevalence of adverse outcomes. Subgroup analysis by asymptomatic/symptomatic carotid stenosis and insulin/noninsulin-dependent DM was performed. RESULTS: A total of 19 studies (n = 122,003) were included. Regarding the short-term outcomes, DM was associated with increased risks of MAEs (ES = 1.52, 95% CI: [1.15-2.01], prevalence = 5.1%), death/stroke (ES = 1.61, 95% CI: [1.13-2.28], prevalence = 2.3%), stroke (ES = 1.55, 95% CI: [1.16-1.55], prevalence = 3.5%), death (ES = 1.70, 95% CI: [1.25-2.31], prevalence =1.2%), and MI (ES = 1.52, 95% CI: [1.15-2.01], prevalence = 1.4%). DM was associated with increased risks of long-term MAEs (ES = 1.24, 95% CI: [1.04-1.49], prevalence = 12.2%). In the subgroup analysis, DM was associated with an increased risk of short-term MAEs, death/stroke, stroke, and MI in asymptomatic patients undergoing CEA and with only short-term MAEs in the symptomatic patients. Both insulin- and noninsulin-dependent DM patients had an increased risk of short-term and long-term MAEs, and insulin-dependent DM was also associated with the short-term risk of death/stroke, death, and MI. CONCLUSIONS In patients with carotid stenosis treated by CEA, DM is associated with short-term and long-term MAEs. DM may have a greater impact on adverse outcomes in asymptomatic patients after CEA. Insulin-dependent DM may have a more significant impact on post-CEA adverse outcomes than noninsulin-dependent DM. Whether DM management could reduce the risk of adverse outcomes after CEA requires further investigation.

Nonalcoholic fatty liver disease (NAFLD) and type 2 Diabetes Mellitus (T2DM) are highly prevalent diseases and are closely associated, with NAFLD being present in the majority of T2DM patients. In Asian traditional medicine, Mori Cortex is widely used for the treatment of diabetes and hyperlipidemia. However, whether it has a therapeutic effect on T2DM associated with NAFLD is still unknown. The present study showed that the oral treatment with Mori Cortex extract (MCE; 10 g·kg·d) lowered the blood lipid levels and reversed insulin resistance (IR) in high fat-diet/streptozotocin-induced type 2 diabetes in rats. The expression levels of sterol receptor element-binding protein-1c (SREBP-1c) and carbohydrate-responsive element binding protein (ChREBP), which are involved in steatosis in NAFLD rats, were measured in the liver samples. MCE decreased the protein and mRNA expression levels of SREBP-1c and ChREBP. In conclusion, down-regulation of SREBP-1c and ChREBP might contribute to the protective effect of MCE on hepatic injury and IR in the rats with T2DM associated with NAFLD.

Objective To assess the efficiency and safety of a novel sodium-glucose co-transporter 2 (SGLT2) inhibitor-SGLT2 inhibitors, in combination with insulin for type 1 diabetes mellitus (T1DM). Methods We searched Medline, Embase, and the Cochrane Collaboration Library to identify the eligible studies published between January 2010 and July 2016 without restriction of language. The Food and Drug Administration (FDA) data and ClinicalTrials (http://www.clinicaltrials.gov) were also searched. The included studies met the following criteria: randomized controlled trials; T1DM patients aged between 18 and 65 years old; patients were treated with insulin plus SGLT2 inhibitors for more than 2 weeks; patients' glycosylated hemoglobin (HbA1c) levels were between 7% and 12%. The SGLT2 inhibitors group was treated with SGLT2 inhibitors plus insulin, and the placebo group received placebo plus insulin treatment. The outcomes should include one of the following items: fasting blood glucose, HbA1c, glycosuria, or adverse effects. Data were analyzed by two physicians independently. The risk of bias was evaluated by using the Cochrane Collaboration's Risk of Bias tool and heterogeneity among studies was assessed using Chi-square test. Random effect model was used to analyze the treatment effects with Revman 5.3.Results Three trials including 178 patients were enrolled. As compared to the placebo group, SGLT2 inhibitor absolutely decreased fasting blood glucose [mean differences (MD) -2.47 mmol/L, 95% confidence interval (CI) -3.65 to -1.28, P<0.001] and insulin dosage (standardized MD -0.75 U, 95%CI -1.17 to -0.33, P<0.001). SGLT2 inhibitors could also increase the excretion of urine glucose (MD 131.09 g/24 h, 95%CI 91.79 to 170.39, P<0.001). There were no significant differences in the incidences of hyperglycemia [odds ratio (OR) 1.82, 95%CI 0.63 to 5.29, P=0.27], urinary tract infection (OR 0.95, 95%CI 0.19 to 4.85, P=0.95), genital tract infection (OR 0.27, 95%CI 0.01 to 7.19, P=0.43), and diabetic ketoacidosis (OR 6.03, 95%CI 0.27 to 135.99, P=0.26) between the two groups.Conclusion SGLT2 inhibitors combined with insulin might be an efficient and safe treatment modality for T1DM patients.

The therapeutic effects and side effects of androgen deprivation therapy (ADT), which is a main treatment method for metastatic prostate cancer, are well known, but the metabolic effects have only recently been studied. This review describes the effects of ADT on body habitus, insulin resistance, lipid profiles, diabetes, metabolic syndrome, and cardiovascular morbidity and mortality. The review was done by using KoreaMed and PubMed to search the medical literature related to prostate cancer, ADT, body habitus, lipid profile, diabetes, insulin resistance, metabolic syndrome, and cardiovascular disease. ADT increases fat mass and decreases lean body mass. Fat mostly accumulates in the subcutaneous area. ADT increases total cholesterol, triglycerides, and high-density lipoprotein, as well as the risk for insulin resistance and diabetes. ADT also increases the risk for cardiovascular events, but insufficient evidence is available for a correlation with mortality. ADT changes body habitus and lipid profiles and has different characteristics than those of classic metabolic syndrome, but it is related to insulin resistance and diabetes. ADT increases the risk for cardiovascular events. No consistent guidelines have been proposed for treating the metabolic effects of ADT, but the generally recommended treatment methods for lowering the risk of diabetes and cardiovascular disease should be fully understood. Additional studies are necessary.

BACKGROUNDThe effectiveness and safety of initiating biphasic insulin aspart 30 in patients who were poorly controlled on oral glucose-lowering drugs were studied in randomized controlled trials, while results from clinical practice remain limited. This subgroup analysis was to provide such findings from a large-scale non-interventional study.

METHODSA1chieve was a multinational, prospective, open-label, non-interventional, 24-week study in patients with type 2 diabetes initiating insulin analogues in 28 countries across Asia, Africa, Europe, and Latin America. After physician had taken the decision to use this insulin, any patient with type 2 diabetes who was not treated with or who had started the study insulin within 4 weeks before inclusion was eligible. Patients were treated with study insulin alone or in combination with oral glucose-lowering drugs. Data on adverse drug reactions, hypoglycemia and glycemic control were collected at baseline, week 12 and 24. This is a report of a Chinese subgroup analysis from the A1chieve study.

RESULTSTotally, 4 100 patients constituted this subgroup. No serious adverse drug reactions were reported. Rates of total, major, nocturnal hypoglycemic events (events/patient per year) were 1.47, 0.10, 0.31 at baseline and 1.35, 0.00, 0.22 at week 24, respectively. Glycemic control was improved as measured by hemoglobin A1c (mean 9.3% to 7.0%, reduction -2.3%), fasting plasma glucose (mean 10.2 to 6.8 mmol/L, reduction -3.5 mmol/L) and postprandial plasma glucose (mean 14.4 to 8.8 mmol/L, reduction -5.6 mmol/L), all P < 0.001. Change in mean body weight was +0.3 kg (P < 0.001).

CONCLUSIONIn this subgroup analysis of the A1chieve study, biphasic insulin aspart 30 improved glycemic control with low risk of hypoglycemia.

We studied the efficacy and safety of acarbose in comparison with voglibose in type 2 diabetes patients whose blood glucose levels were inadequately controlled with basal insulin alone or in combination with metformin (or a sulfonylurea). This study was a 24-week prospective, open-label, randomized, active-controlled multi-center study. Participants were randomized to receive either acarbose (n=59, 300 mg/day) or voglibose (n=62, 0.9 mg/day). The mean HbA1c at week 24 was significantly decreased approximately 0.7% from baseline in both acarbose (from 8.43% +/- 0.71% to 7.71% +/- 0.93%) and voglibose groups (from 8.38% +/- 0.73% to 7.68% +/- 0.94%). The mean fasting plasma glucose level and self-monitoring of blood glucose data from 1 hr before and after each meal were significantly decreased at week 24 in comparison to baseline in both groups. The levels 1 hr after dinner at week 24 were significantly decreased in the acarbose group (from 233.54 +/- 69.38 to 176.80 +/- 46.63 mg/dL) compared with the voglibose group (from 224.18 +/- 70.07 to 193.01 +/- 55.39 mg/dL). In conclusion, both acarbose and voglibose are efficacious and safe in patients with type 2 diabetes who are inadequately controlled with basal insulin. (ClinicalTrials.gov number, NCT00970528)

Berberine is the major component of Coptidis Rhizoma and it has been used as anti-infection, anti-inflammation drug for gastrointestinal diseases. In recent years, evidence showed that it could regulate glucose and lipid metabolism. Moreover, its activity had been tested by clinical trials and animal researches. The mechanisms of berberine in diabetes include: improving the function of beta-cell; prompting insulin secretion and islets regeneration, lowing lipid level, regulating glucose and lipid metabolic by influence transcriptional factors expression such as PPARgamma, C/EBPalpha, SREBP-1c, LXR, having the activities of anti-oxidation and inhibiting reductase to repress oxidative stress state and regulate metabolic signal pathway. Although numbers of data supported that berberine could improving insulin resistance by clinical trials and animal studies, the large scale, multicenter clinical trials are needed to evaluate the effects of berberine for diabetes and its complications in the time of evidence-based medicine.

OBJECTIVETo identify the possible association between C(-106)T polymorphism of the aldose reductase (ALR) gene and diabetic retinopathy (DR) in a cohort of Chinese patients with type 2 diabetes mellitus (T2DM).

METHODSFrom November 2009 to September 2010, patients with T2DM were recruited and assigned to DR group or diabetic without retinopathy (DWR) group according to the duration of diabetes and the grading of 7-field fundus color photographs of both eyes. Genotypes of the C(-106)T polymorphism (rs759853) in ALR gene were analyzed using the MassARRAY genotyping system and an association study was performed.

RESULTSA total of 268 T2DM patients (129 in the DR group and 139 in the DWR group) were included in this study. No statistically significant differences were observed between the 2 groups in the age of diabetes onset (P=0.10) and gender (P=0.78). The success rate of genotyping for the study subjects was 99.6% (267/268), with one case of failure in the DR group. The frequencies of the T allele in the C(-106)T polymorphism were 16.0% (41/256) in the DR group and 19.4% (54/278) in the DWR group (P=0.36). There was no significant difference in the C(-106)T genotypes between the 2 groups (P=0.40). Compared with the wild-type genotype, odds ratio (OR) for the risk of DR was 0.7 (95% CI, 0.38-1.3) for the heterozygous CT genotype and 0.76 (95% CI, 0.18-3.25) for the homozygous TT genotype. The risk of DR was positively associated with microalbuminuria (OR=4.61; 95% CI, 2.34-9.05) and insulin therapy (OR=3.43; 95% CI, 1.94-6.09).

CONCLUSIONSMicroalbuminuria and insulin therapy are associated with the risk of DR in Chinese patients with T2DM. C(-106)T polymorphism of the ALR gene may not be significantly associated with DR in Chinese patients with T2DM.

PURPOSE: Although the presence of cannabinoid type 1 (CB1) receptor in islets has been reported, the major contributor to the protective effect of rimonabant on islet morphology is unknown. We determined whether the protective effect of rimonabant on pancreatic islet morphology is valid in established diabetes and also whether any effect was independent of decreased food intake. MATERIALS AND METHODS: After diabetes was confirmed, Otsuka Long-Evans Tokushima Fatty rats, aged 32 weeks, were treated with rimonabant (30 mg/kg/d, rimonabant group) for 6 weeks. Metabolic profiles and islet morphology of rats treated with rimonabant were compared with those of controls without treatment (control group), a pair-fed control group, and rats treated with rosiglitazone (4 mg/kg/d, rosiglitazone group). RESULTS: Compared to the control group, rats treated with rimonabant exhibited reduced glycated albumin levels (p<0.001), islet fibrosis (p<0.01), and improved glucose tolerance (p<0.05), with no differences from the pair-fed control group. The retroperitoneal adipose tissue mass was lower in the rimonabant group than those of the pair-fed control and rosiglitazone groups (p<0.05). Rimonabant, pair-fed control, and rosiglitazone groups showed decreased insulin resistance and increased adiponectin, with no differences between the rimonabant and pair-fed control groups. CONCLUSION: Rimonabant had a protective effect on islet morphology in vivo even in established diabetes. However, the protective effect was also reproduced by pair-feeding. Thus, the results of this study did not support the significance of islet CB1 receptors in islet protection with rimonabant in established obesity-associated type 2 diabetes.

BACKGROUND/AIMS: Nonalcoholic fatty liver disease (NAFLD) is intimately related to insulin resistance and ranges from a benign course to liver fibrosis and cirrhosis. NAFLD management mainly involves dietary modification and weight loss. Although no fully successful pharmacological intervention is available, alternative therapies to treat NAFLD have shown promising results. Experimental studies have shown that D-002, a mixture of beeswax alcohols with antioxidant effects, is hepatoprotective. The aim of this study was to investigate the efficacy and safety of D-002 in patients with NALFD. METHODS: Fifty patients with NAFLD were randomized to receive a placebo or D-002 (100 mg/day) for 24 weeks. The primary endpoint was a significant ultrasonography-detected reduction of liver fat infiltration versus a placebo. Secondary endpoints were decreases in the homeostatic model assessment (HOMA) index, insulin levels, serum liver enzymes, increases in plasma total antioxidant status (TAS) and improved clinical symptoms versus the placebo recipients. RESULTS: At randomization, all indicators were comparable in both groups. At study completion, seven (28.0%) D-002-patients, but none of the placebo recipients, exhibited a normal liver echo pattern on ultrasonography (p < 0.01). Also, D-002 significantly reduced (p < 0.01 vs. baseline and placebo) the HOMA index and insulin levels and increased the TAS, but did not affect other parameters. The proportion of D-002-patients (12/25, 48.0%) showing symptom improvement was higher (p < 0.001) than that of the placebo group (1/25, 4.0%). The treatment was safe and well tolerated. Three patients in each group withdrew from the study. CONCLUSIONS: D-002 (100 mg/day) improved ultrasonographic findings, indicators of insulin resistance, plasma TAS and clinical evolution on NAFLD patients. Further studies, however, are needed to confirm these results.
