Background/AimsThe protective effects of vitamin D and calcium on colorectal neoplasms are known. Bone mineral density (BMD) may be a reliable biomarker that reflects the long-term anticancer effect of vitamin D and calcium. This study aimed to evaluate the association between BMD and colorectal adenomas including high-risk adenoma.MethodsA multicenter, cross-sectional, case-control study was conducted among participants with average risk of colorectal cancer who underwent BMD and screening colonoscopy between 2015 and 2019. The main outcome was the detection of colorectal neoplasms. The variable under consideration was low BMD (osteopenia/osteoporosis). The logistic regression model included baseline demographics, components of metabolic syndrome, fatty liver disease status, and aspirin and multivitamin use.ResultsA total of 2,109 subjects were enrolled. The mean age was 52.1±10.8 years and 42.6% were male. The adenoma detection rate was 43%. Colorectal adenoma and high-risk adenoma were both more prevalent in subjects with low BMD than those with normal BMD (48.2% vs 38.8% and 12.1% vs 9.1%). In the univariate analysis, old age, male sex, smoking, metabolic components, fatty liver, and osteoporosis were significantly associated with the risk of adenoma and high-risk adenoma. In the multivariate analysis, osteoporosis was independently associated with risk of colorectal adenoma (odds ratio [OR], 1.65; 95% confidence interval [CI], 1.11 to 2.46; p=0.014) and high-risk adenoma (OR, 1.94; 95% CI, 1.14 to 3.29; p=0.014).ConclusionsOsteoporosis is an independent risk factor of colorectal adenoma and high-risk adenoma.  相似文献

Background

We sought to determine whether insulin-sensitizing therapy (thiazolidinediones or metformin) decreased the risk of developing atrial fibrillation compared with insulin-providing therapy (insulin, sulfonylurea, or a meglitinide). Thiazolidinediones are insulin sensitizers that also decrease the inflammatory response. Because inflammation is a risk factor for atrial fibrillation, we hypothesized that treating diabetes with thiazolidinediones might decrease the risk of developing atrial fibrillation.

Methods

The Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial enrolled patients with type 2 diabetes and documented coronary artery disease. All patients were randomized to insulin-sensitizing therapy or insulin-providing therapy.

Results

A total of 2319 patients entered the study, with 1160 assigned to the insulin-sensitization strategy and 1159 assigned to the insulin-provision strategy. Over a median follow-up of 4.2 years, 90 patients (3.9%) developed new-onset atrial fibrillation. In the intention-to-treat analysis, the incidence of atrial fibrillation was 8.7 per 1000 person-years in patients assigned to insulin sensitization compared with 9.5 in patients assigned to insulin provision with a hazard ratio (HR) of 0.91 (95% confidence interval [CI], 0.60-1.38, P = .66). In a time-varying exposure analysis, the incidence rate per 1000 person-years was 7.2 while exposed to thiazolidinediones and 9.7 while not exposed to thiazolidinediones with an adjusted HR of 0.80 (95% CI, 0.33-1.94, P = .62). In a subset of patients matched on propensity to receive a thiazolidinediones, the HR was 0.75 (95% CI, 0.43-1.30, P = .30).

Conclusions

We did not find a significant reduction of atrial fibrillation incidence with use of thiazolidinediones.  相似文献

It has been suggested that kallikrein-kinin system may influence carbohydrate metabolism via a kinin-mediated increment of insulin-mediated glucose uptake. To evaluate the effect of acute inhibition of the kallikrein-kinin system on insulin sensitivity, a randomized, placebo-controlled, double-blind study was performed in 15 male non-insulin-dependent diabetic patients. After basal evaluation of insulin sensitivity with a 2-h euglycaemic hyperinsulinaemic clamp (40 mU m−2 min−1), patients were infused either with aprotinin (200 000 U.I.C. as intravenous bolus injection) or placebo (10 ml isotonic saline) in a cross-over fashion, at 1 week intervals. After both saline and aprotinin infusions, insulin sensitivity was reassessed by continuing the euglycaemic hyperinsulinaemic clamp for a further 1 h. Resulting data showed that aprotinin significantly improved total glucose uptake (from 16.2 ± 2.9 μmol kg min−1 to 20.6 ± 4.9 μmol kg min−1, p<0.01), and decreased metabolic clearance rate of insulin (from 586 ± 57 ml m−2 min−1 to 442 ± 155 ml m−2 min−1, p<0.05). Thus, in spite of the suggested positive effects of kinins on insulin-mediated glucose uptake, acute inhibition of the kallikrein-kinin system resulted in a paradoxical increment of insulin sensitivity, which was probably mediated by the reduced metabolic clearance rate of insulin.  相似文献

Background. The correlation between low insulin levels and a decreased sensitivity of the muscarinic receptor has been shown on induced-diabetes animal models. We designed a cohort study with the aim of evaluating the effects of insulin therapy on airway responsiveness (AR) in human patients with type 2 diabetes mellitus. Methods. We enrolled 92 patients with type 2 diabetes who had switched from oral anti-diabetic therapy to treatment by insulin subcutaneous injection. Patients were administered the methacholine challenge test (MCT) at time 0 (pre-insulin therapy) and at intervals of 15, 30, 90, 180, and 360 days after insulin treatment. The decline of forced expiratory volume in 1 second (FEV1)% from baseline (Δ FEV1) in response to inhaled methacholine (MCH) was determined to assess airway hyper-responsiveness (AHR). Results. A total of 81 patients (18 women and 63 men) completed the study. Their mean age was 58 ± 7 years and the mean duration of disease was 13.5 ± 7.7 years. The mean decrease of FEV1 at pre-insulin assessment was 2.96 ± 2.6%. Compared with the pre-insulin value, a significant increase of Δ FEV1 was observed at 15, 30, and 90 days after treatment (6.25%, CI 95% 5.4 to 7.2, p = 0.0005; 7.64%, CI 95% 6.6 to 8.1, p < 0.001; 6.45%, CI 95% 5.5 to 7.3, p = 0.0004, respectively), while after 180 and 360 days AR was similar to pre-insulin values (Δ FEV1, 3.62%, CI 95% 2.7 to 3.5 and 3.11%, CI 95% 7.9 to 9.3, respectively). Conclusions. The finding of an increased AR in patients with type 2 diabetes during the first 3 months of insulin therapy may underline the importance of monitoring pulmonary function and respiratory symptoms in patients switching from oral anti-diabetic drugs to insulin therapy, especially in the subset of individuals with respiratory disorders.  相似文献

This study was undertaken to clarify the effect of sulphonylurea therapy on beta cell function in 27 subjects with newly diagnosed Type 2 diabetes mellitus. Plasma glucose, insulin, intact and 32/33 split proinsulin were measured at diagnostic OGTT. After 8–12 weeks on a conventional diet, subjects with a fasting glucose > 9 mmol I?1 (n = 12) were commenced on sulphonylurea therapy. At diagnosis, the sulphonylurea requiring group were more hyperglycaemic (p < 0.0001), less obese (p<0.05) and more insulin deficient with a lower 30 min insulin (p < 0.0002) than the diet group. Following dietary intervention in the sulphonylurea group, weight remained unchanged but there was a reduction in fasting glucose (p < 0.009). Fasting insulin, intact proinsulin, and 32/33 split proinsulin remained unchanged. After 12 weeks of sulphonylurea therapy there was a weight gain of 1.5 kg (p < 0.01), but a reduction in fasting glucose (p < 0.0001). Fasting insulin and intact proinsulin increased (p < 0.004) but 32/33 split proinsulin remained unchanged. There was a significant increase in both the fasting insulin to glucose ratio (p < 0.005), and the intact to 32/33 split proinsulin ratio (p < 0.02). Final fasting glucose following sulphonylurea therapy was positively correlated with the initial intact and 32/33 split proinsulin and the fasting glucose following dietary treatment. It is clear from this work that sulphonylureas have a complex effect on beta cell physiology and as well as stimulating release of insulin they increase the release of intact proinsulin but not that of 32/33 split proinsulin, hence they increase the intact to 32/33 split proinsulin ratio.  相似文献

AIM: The aim of this study was to seek an association between the control of type 2 diabetes mellitus (T2DM), as determined by hemoglobin A1c (HbA1c) levels, and the outcome of colorectal cancer (CRC). METHODS: We performed a retrospective review of patients with T2DM who had CRC diagnosed between 1997 and 2001. We defined well-controlled T2DM as HbA1c < 7.5% and poorly controlled T2DM as HbA1c > or = 7.5%. A group of age- and gender-matched patients who had CRC without T2DM were used as controls. Forty clinical factors were reviewed, and those associated with poor clinical outcome in each group were examined by univariate analysis (UA) and by the maximum likelihood analysis of logistic regression to determine the independent predictors of cancer outcome. RESULTS: We identified 155 patients with T2DM and CRC, and 114 control patients who had CRC without T2DM. We found no significant differences in any clinical factor by UA between the patients with well-controlled T2DM and the patients who had CRC without T2DM. Compared to both of those patients groups, in contrast, the patients with poorly controlled T2DM had more right-sided CRCs (P = 0.04, OR = 2, 95% CI = 1-4.1), more advanced CRCs (P = 0.02, OR = 2.1, 95% CI = 1-4.4), a younger age of presentation (P = 0.05), greater use of exogenous insulin (P = 0.002), and a poorer 5-year survival (P = 0.001) by UA. Logistic regression showed that poorly controlled T2DM independently predicted the early onset of CRC, a more advanced stage at the time of presentation, poorer 5-year survival, and an increased incidence of right-sided CRCs. CONCLUSIONS: In patients with T2DM who have CRC, poor glycemic control is associated with a clinically aggressive course for the cancer.  相似文献

People with Type 2 (non-insulin-dependent) diabetes mellitus die mainly from cardiovascular and cerebrovascular disease. Furthermore, the major burden of their symptoms arise from arterial disease, including peripheral vascular disease. However, management guidelines for Type 2 diabetes continue to focus on blood glucose control, which is only one of a number of arterial risk factors found with this type of diabetes. Clinically it is evident that blood glucose control continues to occupy centre-stage in the management of Type 2 diabetes as practised by many physicians. Even when arterial risk factors such as smoking or raised serum triglycerides are noted, their management is often relatively neglected. As part of the St Vincent Declaration Action Programme, a working group has sought consensus on the number and relative importance of arterial risk factors requiring management in quality diabetes care. The group seeks to assist those devising protocols and guidelines, records and quality systems, and those charged with directly advising and educating people with diabetes. Arterial risk factors that can be routinely identified and monitored, and modified by application of management protocols, include high blood pressure, high serum total and LDL cholesterol, low serum HDL cholesterol and raised serum triglycerides, poor blood glucose control, smoking, high body mass index and body fat distribution. Aspirin can modify hypercoagulability, but this is not easily monitored. Arterial risk factors that cannot be modified, but which have an impact on the intensity of management of other factors, include ethnic group, gender, and family history of arterial disease. Raised albumin excretion is an arterial risk factor and can be modified, but it is not clear whether this reduces cardiovascular risk. For many of the risk factors, levels of high, medium, and low risk can be set. These can be used, in consultation with the patient, to determine appropriate interventions and provide feedback on risk reduction resulting from successful management. © 1997 by John Wiley & Sons, Ltd.  相似文献

A simple filter paper technique is described for demonstrating and measuring insulin loss at the injection site in children with type 1 diabetes mellitus. Using this technique in a cohort of 19 children during a 7-day period, measurable fluid was demonstrated at the injection site in 68% of children at least once and was present following 23% of all injections. In nearly 80% of cases the insulin loss probably represented less than 1 unit but could on occasions be 2 units or more or up to 18% of the injected dose. Insulin losses were observed following injections given by children themselves and by parents. There was no significant relationship between insulin dose and insulin loss. Insulin losses at the injection site are frequent and, although usually small in amount, are a potential source of blood glucose variability.  相似文献

Background/Aims

Autoimmune pancreatitis (AIP) is frequently associated with diabetes mellitus (DM). This study evaluated the effect of steroid therapy on the course of DM in AIP.

Methods

Glucose tolerance was examined in 69 patients with AIP. DM onset was classified as either a simultaneous onset with AIP or an exacerbation of pre-existing DM. Based on the changes in the HbA1c levels and insulin dose, the responses of DM to steroids were classified as improved, no change, or worsened.

Results

Thirty (46%) patients were diagnosed as having DM (simultaneous onset, n=17; pre-existing, n=13). Three months after starting the steroid treatment, the DM improved in 13 (54%) of 24 DM patients. The DM improved in 55%, had no change in 36%, and worsened in 9% of the 11 simultaneous onset DM patients, and it improved in 54%, had no change in 31%, and worsened in 15% of the 13 pre-existing DM patients. At approximately 3 years after starting the steroid treatment, the DM improved in 10 (63%) of 16 patients. The pancreatic exocrine function improved in parallel with the changes in the DM in seven patients.

Conclusions

Because approximately 60% of DM associated with AIP is responsive to steroids in the short- and long-terms, marked DM associated with AIP appears to be an indication for steroid therapy.  相似文献
