In general population obesity is regarded as a predisposing factor for chronic disease such as type 2 diabetes and cardiovascular disease. Obesity increases the risk of kidney disease and adversely affects the progress of kidney disease among patients with diagnosed kidney disease. The main reason of mortality in chronic kidney disease patients is cardiovascular disease, however, the real meaning of obesity as a risk factor of cardiovascular diseases is still uncertain. While in a general population obesity causes higher cardiovascular mortality, many studies reflect inverse association in chronic kidney disease patients. Obesity is associated with better survival, contrary to general population obesity appears to be a protective factor of cardiovascular disease. The name of this phenomenon is "reverse epidemiology" or "obesity paradox", in dialysis patients known as a "risk-factor-paradox". Some studies do not confirm this paradox association in patients with chronic kidney disease. 相似文献

OBJECTIVE: To assess the degree of control of modifiable cardiovascular risk factors (CRFs) in type 2 diabetic patients. STUDY DESIGN AND METHODS: Cross-sectional study in 501 patients with type 2 diabetes mellitus. The following parameters were used to define optimal control: glycated haemoglobin (HbA(1C)) <7.0%, fasting plasma glucose (FPG) <7.2 mmol/l, postprandial capillary glucose (PCG) <10.0 mmol/l, high-density lipoprotein cholesterol (HDL-C) >1.1 mmol/l, low-density lipoprotein cholesterol (LDL-C) <2.6 mmol/l, triglyceride levels (TG) <1.7 mmol/l, systolic blood pressure (SBP) <130 mmHg, diastolic blood pressure (DBP) <80 mmHg, body mass index (BMI) <25 kg/m2, waist circumference (WC) <88 cm in women and <102 cm in men, and current non-smoking status. The use of various cardioprotective medications was also evaluated. RESULTS: Mean (+/-S.D.) age was 65.4 +/- 11.9 years, 218 (44%) were male. Ninety-six (19%) met coronary artery disease (CAD). Two hundred seven patients (41%) had an HbA(1C) <7.0%, 134 (27%) a FPG <7.2 mmol/l and 231 of 353 (65%) a PCG <10.0 mmol/l. Only 206 (41%) achieved an LDL-C <2.6 mmol/l, but 370 (74%) and 308 (62%) reached an HDL-C >1.1 mmol/l and a TG levels <1.7 mmol/l, respectively. In 359 (72%) patients DBP was <80 mmHg, but in only 136 (27%) was SBP <130 mmHg. Sixty four (13%) achieved a BMI <25 kg/m2, and 420 (84%) were non-smokers. Forty three (15%) women and 104 (48%) men had a WC <88 or <102 cm, respectively. None of the patients had optimal control of all CRFs. CONCLUSIONS: These data demonstrate poor control of modifiable CRFs in the population studied, and support the need for great effort to achieve the recommended goals. 相似文献

Patients with type 2 diabetes (T2D) are at an increased risk of cardiovascular disease (CVD). Cardiovascular risk in these patients should be considered as a continuum, and comprehensive treatment strategies should aim to target multiple disease risk factors. Large-scale clinical trials of sodium-glucose co-transporter-2 (SGLT2) inhibitors have shown an impact on cardiovascular outcomes, including heart failure hospitalization and cardiovascular death, which appears to be independent of their glucose-lowering efficacy. Reductions in major cardiovascular events appear to be greatest in patients with established CVD, particularly those with prior myocardial infarction, but are independent of heart failure or renal risk. Most large-scale trials of SGLT2 inhibitors predominantly include patients with T2D with pre-existing CVD and high cardiovascular risk at baseline, limiting their applicability to patients typically observed in clinical practice. Real-world evidence from observational studies suggests that there might also be beneficial effects of SGLT2 inhibitors on heart failure hospitalization and all-cause mortality in various cohorts of lower risk patients. The most common adverse events reported in clinical and observational studies are genital infections; however, the overall risk of these events appears to be low and easily managed. Similar safety profiles have been reported for elderly and younger patients. There is still some debate regarding the safety of canagliflozin in patients at high risk of fracture and amputation. Outstanding questions include specific patterns of cardiovascular protection according to baseline risk. 相似文献

After the successful introduction of highly active antiretroviral agents the survival of patients infected with the human immunodeficiency virus (HIV) in developed countries has increased substantially. This has allowed the surfacing of several chronic diseases among which cardiovascular disease (CVD) is prominent. The pathogenesis of CVD in HIV is complex and involves a combination of traditional and HIV related factors. An accurate assessment of risk of CVD in these patients is still elusive and as a consequence the most appropriate preventive and therapeutic interventions remain controversial. 相似文献

Premature coronary heart disease (CHD) is a major cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). In certain age groups, the risk can be >50 times that of an age-matched population. This population also has an increased prevalence of several key classic risk factors that contribute to the CHD development. Chronic inflammation, anti-phospholipid antibodies and exposure to steroid therapy are also likely to have an impact. We have adopted a proactive approach to classic risk factor management with 'ideal targets' based on viewing SLE as a CHD equivalent condition. In this context, a significant proportion of SLE patients (approximately 30%) will require statins and the majority would be treated with aspirin prophylaxis. Better control of the underlying inflammatory disease is also likely to play an important role and the relative safety of anti-malarials allows their consideration as an adjunct in a large proportion of patients. Well-conducted clinical trials are now needed to advance beyond these initial recommendations. 相似文献

Oxidative stress is suspected to intervene in certain chronic diseases. Much research has been devoted to the relationship between vitamin E, a major lipid-soluble antioxidant, and certain widespread diseases. Experimental and epidemiological proof supports a protective effect of vitamin E in a number of pathological processes such as coronary heart disease, cancer, cataract, diabetes mellitus, and Alzheimer disease. Randomized clinical trials have not confirmed a beneficial effect of vitamin E supplementation on the progression of these diseases. Certain methodological biases could however have affected these studies, explaining conflicting results. These biases include inaccuracy of vitamin E intake estimates and changes in eating habits during the course of the survey. An insufficient supplementation period using an insufficient dose and inclusion of aged and high-risk patients are the main limitations of the reported clinical trials. Large scale randomized clinical trials including healthy and low-risk subjects, along with prolonged administration of high-dose natural vitamin E, associated with synergetic compounds, and testing on morphological or biological features, will allow a better understanding of the relationship between vitamin E and chronic diseases. 相似文献

PURPOSE: The purpose of this study was to determine the extent to which diabetes education encounters include evidence-based content aimed at reducing the risk of cardiovascular disease. METHODS: During a 2-week period in November 2001, 3 certified diabetes educators (CDEs) listed the statements they made while teaching patients. These statements/comments were then assigned to the 7 outcome areas identified by the Diabetes Self-Management Assessment Report Tool (D-SMART). All educational encounters completed during that same month by 21 educators were reviewed for content areas or modules consistent with the American Diabetes Association National Standards. RESULTS: Of all statements made by the 3 CDEs, 63% were about glycemic control while only 5% were directly relevant to cardiovascular risk reduction. There were 1043 educational encounters in November 2001, of which only 10% targeted cardiovascular risk. Educators focused most of their educational efforts (62%) on glycemic control. CONCLUSIONS: Despite its potential impact and strong evidence base, diabetes education gives little attention to the reduction of cardiovascular risk. Diabetes educators should emphasize interventions that are most likely to be effective in reducing cardiovascular morbidity and mortality in patients with diabetes. 相似文献

The inflammatory bowel diseases (IBD), Crohn's disease (CD) and ulcerative colitis (UC), may be complicated by colorectal cancer (CRC). In a recent population-based cohort study of 47 347 Danish patients with IBD by Tine Jess and colleagues 268 patients with UC and 70 patients with CD developed CRC during 30 years of observation. The overall risk of CRC among patients with UC and CD was comparable with that of the general population. However, patients diagnosed with UC during childhood or as adolescents, patients with long duration of disease and those with concomitant primary sclerosing cholangitis were at increased risk. In this commentary, we discuss the mechanisms underlying carcinogenesis in IBD and current investigations of genetic susceptibility in IBD patients. Further advances will depend on the cooperative work by epidemiologist and molecular geneticists in order to identify genetic polymorphisms involved in IBD-associated CRC. The ultimate goal is to incorporate genotypes and clinical parameters into a predictive model that will refine the prediction of risk for CRC in colonic IBD. The challenge will be to translate these new findings into clinical practice and to determine appropriate preventive strategies in order to avoid CRC in IBD patients. The achieved knowledge may also be relevant for other inflammation-associated cancers. 相似文献

PURPOSE: To assess the clinical and economic effects of disease management in patients with chronic diseases. METHODS: Electronic databases were searched for English-language articles from 1987 to 2001. Articles were included if they used a systematic approach to care and evaluated patients with chronic disease, reported objective measurements of the processes or outcomes of care, and employed acceptable experimental or quasi-experimental study designs as defined by the Cochrane Effective Practice and Organization of Care Group. RESULTS: Two reviewers evaluated 16,917 titles and identified 102 studies that met the inclusion criteria. Identified studies represented 11 chronic conditions: depression, diabetes, rheumatoid arthritis, chronic pain, coronary artery disease, asthma, heart failure, back pain, chronic obstructive pulmonary disease, hypertension, and hyperlipidemia. Disease management programs for patients with depression had the highest percentage of comparisons (48% [41/86]) showing substantial improvements in patient care, whereas programs for patients with chronic obstructive pulmonary disease (9% [2/22]) or chronic pain (8% [1/12]) appeared to be the least effective. Of the outcomes more frequently studied, disease management appeared to improve patient satisfaction (71% [12/17]), patient adherence (47% [17/36]), and disease control (45% [33/74]) most commonly and cost-related outcomes least frequently (11% to 16%). CONCLUSION: Disease management programs were associated with marked improvements in many different processes and outcomes of care. Few studies demonstrated a notable reduction in costs. Further research is needed to understand how disease management can most effectively improve the quality and cost of care for patients with chronic diseases. 相似文献
