Patients With Diabetes

PurposeDetailed population-based data are essential to understanding the epidemiology of diabetes and its clinical course. This article describes the Funen Diabetes Database (FDDB). The purpose of the FDDB was to serve as a shared electronic medical record system for healthcare professionals treating patients with diabetes. The cohort can also be used for research.ParticipantsThe FDDB covers a geographical area of almost 500 000 Danish inhabitants. It currently includes 3691 patients with type 1 diabetes, 19 085 patients with type 2 diabetes, 292 patients with other types of diabetes and 5992 patients with an unknown type of diabetes. Patients have been continuously enrolled from general practitioners and endocrinology departments in the Funen area in Denmark since 2003. Patients undergo a clinical work-up at their first diabetes contact and during follow-up visits. The information collected includes type of diabetes contact, blood pressure, height, weight, lifestyle factors (smoking, exercise), laboratory records (eg, haemoglobin A1c and cholesterol levels), results from foot examinations (eg, pulse, cutaneous sensitivity and ankle brachial index), results from eye examinations (eg, degree of retinopathy assessed by retinal photo and eye examination), glucose-lowering drugs and diabetic complications.Findings to dateThe FDDB cohort was followed for a total of 212 234 person-years up to 2016. A cross-sectional study described the prevalence of diabetic retinopathy and its associated risk factors. The clinical outcomes of patients with type 1 diabetes, type 2 diabetes and latent autoimmune diabetes in adults have been assessed. Linkage to population-based medical registries with complete follow-up has enabled the collection of extensive continuous data on general practice contacts, diagnoses and procedures from hospital contacts, medication use and mortality.Future plansThe FDDB serves as a strong data resource that will be used in future studies of diabetes epidemiology with focus on occurrence, risk factors, treatment, complications and prognosis.

Increasing Trends

A pandemic refers to a disease that is rapidly increasing in frequency across many populations, over a wide geographical area (1). Put another way, it refers to the situation in which epidemics of the disease are occurring simultaneously in many countries. This is the case for diabetes, which has the dubious distinction of being one of the few chronic non-communicable diseases known to be increasing in all countries from which data are available, irrespective of the level of economic development (2). This is mirrored by a pandemic of people who are overweight or obese (3), the major risk factors for type 2 diabetes. This chapter focuses on diabetes in adults (aged 20 years old and above), of which 85% to more than 95%, depending on the population, have type 2 diabetes (2, 4), which is thus the main contributor to the growing burden of diabetes. However, it is worth noting that, in children (<15 years old), the incidence of type 1 diabetes is also increasing, particularly in the youngest age groups, across the vast majority of countries from which good data are available (5). The reasons for this increase are unclear, although various environmental risk factors have been implicated (5). This chapter aims to do the following: ◆ provide an overview of the prevalence and trends in diabetes in adults across the world and its contribution to mortality ◆ describe the broad determinants that underlie the increasing trends in diabetes in adults ◆ provide an introduction to variations by ethnicity in the prevalence of type 2 diabetes

Background. Diabetes mellitus (DM) is characterized by multiple risk factors for the combined development of disorders of phosphorus-calcium metabolism, due to more frequent overweight, decreased renal filtration function and vitamin D deficiency in this category of patients. Aim. To assess the level of calcium in blood serum and its correlations with parameters of carbohydrate metabolism, body mass index (BMI) and renal function in patients with type 1 and type 2 diabetes. Materials and methods. The object of the study: adult patients with type 1 diabetes (T1DM) and type 2 diabetes (T2DM) ≥18 years old who underwent examination in Diamodule (n=294) in 2019 in the Voronezh region, who were additionally tested for serum calcium. The examination at the mobile medical center includes: assessment of anthropometric data (height, weight, BMI), biochemical data of blood lipids and creatinine levels with calculation of glomerular filtration rate (GFR-EPI), albuminuria and the albumin/creatinine in a single portion of urine, measurement of glycated hemoglobin (HbA1c), blood pressure, electrocardiogram, consultation with a cardiologist, ophthalmologist, specialist of the Diabetic Foot office, diabetologist. All biochemical parameters was carried out using commercial kits on a biochemical express analyzer Spotchem EZ ArkraySP-4430. Determination of HbA1c, albuminuria, albumin/creatinine was performed by immunochemical method on a DCA Vantage analyzer. Data analysis was carried out using the Statistica v.13.3 software package (TIBCO Software Inc., USA). The results are presented as medians and quartiles [25; 75], the level of reliability is taken as p<0.05. Results. Hypocalcemia (serum calcium level less 2.15 mmol/L) was detected in 88.3% of patients with T1DM and 73.6% of patients with T2DM. The level of serum calcium in T1DM was 1.96 [1.83; 2.07], in T2DM – 2.04 [1.97; 2.16] (p<0.001) with significant differences in GFR: in T1DM 69.6 [57.8; 82.5], with T2DM 50.5 [44.1; 59.9] (p<0.001). We observed correlation between GFR and calcium level r=-0.3 (p<0.05,). GFR<60 ml/min/1.73 m² was observed in 30.5% of T1DM patients, in 75.0% of T2DM. The HbA1c in T1DM was 8.7% [7.7; 9.8], in T2DM – 8.3% [6.8; 9.4] (p=0.01). Obesity was revealed in T1DM in 12.3%, in T2DM in 71.4%; the median BMI in T1DM was 25.5 kg/m2 [21.9; 28.4], in T2DM – 33.2 kg/m2 [29.7; 37.9]. There was correlation between BMI and calcium level r=0.26 (p<0.05). Conclusion. The results of the study revealed a high prevalence of hypocalcemia among patients with diabetes, the most pronounced in type 1 diabetes. In the presence of a correlation between calcium and GFR, there was a high incidence of hypocalcemia in patients with T1DM, even in the absence of a significant decrease in GFR, which may indicate to additional risk factors. Since the assessment of the level of calcium is not included in the list of standard clinical examination, it is recommended to include this parameter and conduct regular screening in risk groups, which include patients with diabetes. More extensive research is needed to analyze the factors.

The Impact

Diabetes – a disease in which the effect of the treatment substantially depends on the patient. Known a study showed that the use of glucometers with the technology of three-color display of test results facilitates self-monitoring of blood sugar and leads to a decrease in glycated hemoglobin (HbAlc). Purpose of the study: to modeling the impact of using of a glucometer with a color-coded display on the clinical outcomes of diabetes mellitus and calculating, the potential economic benefits of reducing the hospitalization rate of patients with diabetes. Material and methods. Based on data from two studies (O. Schnell et al. and M. Baxter et al.) simulation of the reduction in the number of complications with the use of a glucometer with a color indication. In a study by O. Schnell et al. a decrease of HbA1c by 0.69 percent is shown when using the considered type of glucometers, which was the basis of the model. Results. In the model, the use of a glucometer with a color-coded display for type 1 diabetes led to a decrease in the total number of complications by 9.2 thousand over 5 years per a cohort of 40 thousand patients with different initial levels of HbA1c. In a cohort of 40 thousand patients with type 2 diabetes, the simulated number of prevented complications was 1.7 thousand over 5 years. When extrapolating these data to all patients with diabetes included in the federal register of diabetes mellitus (FRD), the number of prevented complications was 55.4 thousand cases for type 1 diabetes and 67.1 thousand cases for type 2 diabetes. The possible economic effect from the use of the device by all patients with a diagnosis of diabetes, which are included in the FRD, estimated at 1.5 billion rubles for a cohort of patients with type 1 diabetes and 5.3 billion rubles for patients with type 2 diabetes. Conclusion. Improving the effectiveness of self-monitoring, which is the result of the use of glucometers with color indicators, can potentially significantly reduce the incidence of complications in diabetes and thereby provide significant economic benefits to society.

Reducing Carbohydrates

Low-carb and ketogenic diets are popular among clinicians and patients, but the appropriateness of reducing carbohydrates intake in obese patients and in patients with diabetes is still debated. Studies in the literature are indeed controversial, possibly because these diets are generally poorly defined; this, together with the intrinsic complexity of dietary interventions, makes it difficult to compare results from different studies. Despite the evidence that reducing carbohydrates intake lowers body weight and, in patients with type 2 diabetes, improves glucose control, few data are available about sustainability, safety and efficacy in the long-term. In this review we explored the possible role of low-carb and ketogenic diets in the pathogenesis and management of type 2 diabetes and obesity. Furthermore, we also reviewed evidence of carbohydrates restriction in both pathogenesis of type 1 diabetes, through gut microbiota modification, and treatment of type 1 diabetes, addressing the legitimate concerns about the use of such diets in patients who are ketosis-prone and often have not completed their growth.

Abstract Background Both type 1 and type 2 diabetes are well-established risk factors for cardiovascular disease and early mortality. However, few studies have directly compared the hazards of cardiovascular outcomes and premature death among people with type 1 diabetes to those among people with type 2 diabetes and subjects without diabetes. Furthermore, information about the hazard of cardiovascular disease and early mortality among Asians with type 1 diabetes is sparse, although the clinical and epidemiological characteristics of Asians with type 1 diabetes are unlike those of Europeans. We estimated the hazard of myocardial infarction (MI), hospitalization for heart failure (HF), atrial fibrillation (AF), and mortality during follow-up in Korean adults with type 1 diabetes compared with those without diabetes and those with type 2 diabetes. Methods We used Korean National Health Insurance Service datasets of preventive health check-ups from 2009 to 2016 in this retrospective longitudinal study. The hazard ratios of MI, HF, AF, and mortality during follow-up were analyzed using the Cox regression analyses according to the presence and type of diabetes in ≥ 20-year-old individuals without baseline cardiovascular disease (N = 20,423,051). The presence and type of diabetes was determined based on the presence of type 1 or type 2 diabetes at baseline. Results During more than 93,300,000 person-years of follow-up, there were 116,649 MIs, 135,532 AF cases, 125,997 hospitalizations for HF, and 344,516 deaths. The fully-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for incident MI, hospitalized HF, AF, and all-cause death within the mean follow-up of 4.6 years were higher in the type 1 diabetes group than the type 2 diabetes [HR (95% CI) 1.679 (1.490–1.893) for MI; 2.105 (1.901–2.330) for HF; 1.608 (1.411–1.833) for AF; 1.884 (1.762–2.013) for death] and non-diabetes groups [HR (95% CI) 2.411 (2.138–2.718) for MI; 3.024 (2.730–3.350) for HF; 1.748 (1.534–1.993) for AF; 2.874 (2.689–3.073) for death]. Conclusions In Korea, the presence of diabetes was associated with a higher hazard of cardiovascular disease and all-cause death. Specifically, people with type 1 diabetes had a higher hazard of cardiovascular disease and all-cause mortality compared to people with type 2 diabetes.

Objective: To assess the total prevalence of types 1 and 2 diabetes and to describe and compare cardiovascular risk factors, vascular complications and the quality of diabetes care in adults with types 1 and 2 diabetes in Salten, Norway. Research design and methods: Cross-sectional study including all patients with diagnosed diabetes in primary and specialist care in Salten, 2014 (population 80,338). Differences in cardiovascular risk factors, prevalence of vascular complications and attained treatment targets between diabetes types were assessed using regression analyses. Results: We identified 3091 cases of diabetes, giving a total prevalence in all age groups of 3.8%, 3.4% and 0.45% for types 2 and 1 diabetes, respectively. In the age group 30–89 years the prevalence of type 2 diabetes was 5.3%. Among 3027 adults aged 18 years and older with diabetes, 2713 (89.6%) had type 2 and 304 (10.0%) type 1 diabetes. The treatment target for haemoglobin A1c (⩽7.0%/53 mmol/mol) was reached in 61.1% and 22.5% of types 2 and 1 diabetes patients, respectively. After adjusting for age, sex and diabetes duration we found differences between patients with types 2 and 1 diabetes in mean haemoglobin A1c (7.1% vs. 7.5%, P<0.001), blood pressure (136/78 mmHg vs. 131/74 mmHg, P<0.001) and prevalence of coronary heart disease (23.1% vs. 15.8%, P<0.001). Conclusions: The prevalence of diagnosed type 2 diabetes was slightly lower than anticipated. Glycaemic control was not satisfactory in the majority of patients with type 1 diabetes. Coronary heart disease was more prevalent in patients with type 2 diabetes.

Objective Bone turnover has a diurnal variation influenced by food intake, incretin hormones, the sympathetic nervous system and osteocyte function. The aim of the study was to compare diurnal variation in bone turnover in patients with diabetes and controls. Design A clinical 24-h study with patients with type 1 diabetes (n = 5), patients with type 2 diabetes (n = 5) and controls (n = 5). Methods Inclusion criterion: age >50 years. Exclusion criteria: diseases/medication that affect bone metabolism or recent use of incretin-based drugs. We drew blood samples hourly during the day and every 3 h during the night. We served an identical diet on all study days. We used repeated-measures one-way ANOVA to compare the levels of the investigated markers, and we quantified the effect of time by comparing group mean standard deviations. Results The bone formation marker procollagen type 1 N-terminal propeptide showed a significant interaction between time and group (P = 0.01), and the mean standard deviation was lower in patients with type 2 diabetes compared with controls (P = 0.04) and patients with type 1 diabetes (P = 0.02). Other markers of bone formation and resorption showed significant effect of time. Levels of glucagon-like peptide-2, glucose-dependent insulinotropic peptide and sclerostin only showed significant effect of time (all P values 0.01), but levels of sclerostin tended to being highest in type 2 diabetes and lowest in controls. Conclusions The diurnal variation in bone formation is attenuated in patients with type 2 diabetes. This is not explained by changes in incretin hormone levels, but possibly mediated by sclerostin.

Abstract Background Although diabetes is a common complication of acromegaly or Cushing´s disease, there are only few detailed studies with a focus on cardiovascular risk, metabolic control or diabetes therapy. Here, we provide a comprehensive characterization from the longitudinal DPV (Diabetes Patienten Verlaufsdokumentation) registry. Methods Patients from the registry≥18 years of age with diabetes and acromegaly or Cushing´s disease were compared to patients with type 1 diabetes or type 2 diabetes using the statistical software SAS 9.4. Results Patients with diabetes and acromegaly (n=52) or Cushing’s disease (n=15) were significantly younger at diabetes onset (median age 50.1 and 45.0 vs. 59.0 years in type 2 diabetes; both p<0.05). Dyslipidemia was common in both diseases (71.0% and 88.9% vs. 71.8% in type 2 diabetes; n.s.), while hypertension was most frequent in acromegaly (56.8% vs. 20.9% in type 1 diabetes, p<0.00001). 36.5% of patients with acromegaly and 46.7% with Cushing´s disease receive insulin, compared to 50.4% with type 2 diabetes. Oral antidiabetic drugs were used in 36.5% of patients with acromegaly and 40% with Cushing´s disease, with a predominance of biguanides and dipeptidyl peptidase-4 inhibitors. HbA1c was well controlled in both groups (median 7.0% and 6.5%; vs. 7.2% in type 2 diabetes). Conclusion Patients with acromegaly are at a high risk for cardiovascular disease, reflected by dyslipidemia and hypertension. A high proportion of patients with diabetes in acromegaly or Cushing´s disease receives insulin. Based on a multicenter register, a sufficient number of patients with rare forms of diabetes can be analyzed.
