Unrecognised cardiovascular disease in type 2 diabetes: is it time to act earlier?

Cardiovascular disease (CVD) is the most significant prognostic factor in individuals with type 2 diabetes (T2D). However, a significant number of individuals may develop CVD that does not present with the classic angina-related or heart failure symptoms. In these cases, CVD may seem to be 'silent' or 'asymptomatic', but may be more accurately characterised as unrecognised diabetic cardiac impairment. An initial step to raise awareness of unrecognised CVD in individuals with T2D would be to reach a consensus regarding the terminology used to describe this phenomenon. By standardising the terminologies, and agreeing on the implementation of an efficient screening program, it is anticipated that patients will receive an earlier diagnosis and appropriate and timely treatment. Given the availability of anti-diabetic medications that have been shown to concomitantly reduce CV risk and mortality, it is imperative to improve early identification and initiate treatment as soon as possible in order to enable as many patients with T2D as possible to benefit.

Translating recent results from the Cardiovascular Outcomes Trials into clinical practice: recommendations from the Central and Eastern European Diabetes Expert Group (CEEDEG).

AIMS: These recommendations aim to improve care for patients with type 2 diabetes (T2D) at high cardiovascular (CV) risk in Central and Eastern Europe. Cardiovascular disease (CVD) and/or chronic kidney disease (CKD) are major interdependent comorbidities in patients with T2D, accounting for 50% of mortality. Following recent CV outcomes trial (CVOT) results, including those from EMPA-REG OUTCOME®, LEADER®, SUSTAIN™-6 and, most recently, the CANVAS study, it is essential to develop regional expert consensus recommendations to aid physicians in interpreting these newest data to clinical practice. METHODS: The Central and Eastern European Diabetes Expert Group (CEEDEG) followed a Delphi method to develop treatment algorithms to aid physicians in the clinical management of patients with T2D at high CV risk. RESULTS: In light of the latest CVOT results, and in particular the EMPA-REG OUTCOME® and LEADER® trials, the diagnosis, assessment, treatment choice and monitoring of patients with T2D and established CVD and/or CKD have been considered together with existing guidelines and presented in two reference algorithms. In addition, adherence, special prescribing considerations and a proposed multidisciplinary management approach have been discussed and are presented with the proposed algorithms. CONCLUSIONS: The latest available high-level evidence on glucose-lowering drugs has enabled CEEDEG to develop practical consensus recommendations for patients with established CVD and/or CKD. These recommendations represent an update to international and country-level guidelines used for these patients, with the aim of providing a resource not only to endocrinologists, but to cardiologists, nephrologists and primary care physicians in the region.

Impact of creatinine methodology on glomerular filtration rate estimation in diabetes.

AIM: To evaluate the influence of creatinine methodology on the performance of chronic kidney disease (CKD)-Epidemiology Collaboration Group-calculated estimated glomerular filtration rate (CKD-EPI-eGFR) for CKD diagnosis/staging in a large cohort of diabetic patients. METHODS: Fasting blood samples were taken from diabetic patients attending our clinic for their regular annual examination, including laboratory measurement of serum creatinine and eGFR. RESULTS: Our results indicated an overall excellent agreement in CKD staging (kappa = 0.918) between the Jaffé serum creatinine- and enzymatic serum creatinine-based CKD-EPI-eGFR, with 9% of discordant cases. As compared to the enzymatic creatinine, the majority of discordances (8%) were positive, i.e., associated with the more advanced CKD stage re-classification, whereas only 1% of cases were negatively discordant if Jaffé creatinine was used for eGFR calculation. A minor proportion of the discordant cases (3.5%) were re-classified into clinically relevant CKD stage indicating mildly to moderately decreased kidney function (< 60 mL/min per 1.73 m2). Significant acute and chronic hyperglycaemia, assessed as plasma glucose and HbA1c levels far above the recommended glycaemic goals, was associated with positively discordant cases. Due to a very low frequency, positive discordance is not likely to present a great burden for the health-care providers, while intensified medical care may actually be beneficial for the small number of discordant patients. On the other hand, a very low proportion of negatively discordant cases (1%) at the 60 mL/min per 1.73 m2 eGFR level indicate a negligible possibility to miss the CKD diagnosis, which could be the most prominent clinical problem affecting patient care, considering high risk of CKD for adverse patient outcomes. CONCLUSION: This study indicate that compensated Jaffé creatinine procedure, in spite of the glucose-dependent bias, is not inferior to enzymatic creatinine in CKD diagnosis/staging and therefore may provide a reliable and cost-effective tool for the renal function assessment in diabetic patients.

Metabolic implications of menstrual cycle length in non-hyperandrogenic women with polycystic ovarian morphology.

This cross-sectional study aimed to investigate the association between menstrual cycle lenght and metabolic parameters in non-hyperandrogenic women with polycystic ovarian morphology, n = 250. Metabolic profiles of all participants were evaluated using anthropometric parameters (body mass index, waist circumference), parameters of dyslipidemia (total cholesterol, HDL-cholesterol, triglycerides) and markers of insulin resistance (fasting insulin, homeostasis model assessment for insulin resistance index). The associations between menstrual cycle lenght and cardiometabolic risk factors such as insulin resistance, dyslipidemia, and obesity were investigated. In non-hyperandrogenic women with polycystic ovarian morphology, menstrual cycle lenght was associated with hypertriglyceridemia and insulin resistance independently of body mass index. Moreover, menstrual cycle lenght added value to body mass index in predicting hypertriglyceridemia. The optimal menstrual cycle lenght cut-off value for identifying of non-hyperandrogenic women with polycystic ovarian morphology at metabolic risk was found to be 45 days. Metabolic profile of non-hyperandrogenic women with polycystic ovarian morphology (n = 75) with menstrual cycle lenght >45 days was similar to that of hyperandrogenic women with polycystic ovarian morphology (n = 138) while metabolic profile of non-hyperandrogenic women with polycystic ovarian morphology with menstrual cycle lenght ≤45 days (n = 112) was similar to that of controls (n = 167). Non-hyperandrogenic women with polycystic ovarian morphology with menstrual cycle lenght >45 days had higher prevalence of cardiometabolic risk factors compared to those with menstrual cycle lenght ≤45 days. Non-hyperandrogenic women with polycystic ovarian morphology are not metabolically homogeneous. Menstrual cycle lenght is an easy-to-obtain clinical parameter positively associated with the probability of unfavorable metabolic status in non-hyperandrogenic women with polycystic ovarian morphology. Menstrual cycle lenght cut-off value of 45 days was found to have the best capacity in discriminating non-hyperandrogenic women with polycystic ovarian morphology with and without metabolic derangement(s) corroborating in favor of the cardiometabolic risk factors screening and management in non-hyperandrogenic women with polycystic ovarian morphology with menstrual cycle lenght >45 days through strategies for prevention of cardiovascular disease.
