Insulin Management of Patients with Inadequately Controlled Type 2 Diabetes Admitted to Hospital: Titration Patterns and Frequency of Hypoglycemia as Results of a Prospective Observational Study (Hospital Study).

INTRODUCTION: Despite the continuously growing number of therapeutic options for type 2 diabetes mellitus (T2DM) including insulins, a large percentage of patients fail to achieve HbA1c targets. Several real-world studies focused on patients with T2DM receiving insulin treatment in outpatient settings were conducted, but information about real-world in-hospital insulin management is lacking. The aim of this study was to describe the management of insulin therapy with a focus on basal-bolus and premixed insulin regimens in patients with T2DM under routine in-hospital medical practice in the Czech Republic. METHODS: This non-interventional prospective study was conducted from June 2014 to December 2017 in 22 centers in the Czech Republic under routine clinical practice conditions. Adult patients admitted to hospital with metabolically uncontrolled T2DM [HbA1c ≥ 60 mmol/mol; > 7.6% Diabetes Control and Complications Trial (DCCT)] and there treated with basal-bolus and premixed insulin regimens were documented during hospitalization. RESULTS: Overall, 369 patients with T2DM (54.7% male, mean age 64.44 ± 13.84 years, BMI 31.10 ± 6.00 kg/m2, duration of diabetes 8.11 ± 9.93 years, HbA1c 95.90 ± 24.38 mmol/mol, length of stay was 7.94 ± 4.53 days) were included. The percentage of glucose values under 10 mmol/l at time of randomization (the group with basal-bolus insulin regimen vs. the premix insulin regimen group) was 24.2% vs. 33.5% (p = 0.053), at time of first insulin dose adjustment it was 43.1% vs. 50.0% (p = 0.330), and 1 day before hospital discharge it was 61.7% vs. 61.4% (p = 0.107). A hypoglycemic event occurred in a total of 15 patients in the basal-bolus regimen group, and no hypoglycemic event occurred in the premixed insulin regimen group. CONCLUSION: In-hospital insulin management regarding basal-bolus and premixed insulin regimens is safe and in concordance with current international recommendations.

Long term use of the telemonitoring system Diani in the therapy of a patient with type 1 diabetes.

Mobile and wearable technologies offer patients with diabetes mellitus new possibilities for data collection and their more effective analysis. The Diabesdagboga smartphone application and the Diani web portal enable to collect and analyze glycaemia values, carbohydrates intake, insulin doses and the level of physical activity. The data are not only accessible in the corresponding smartphone but also automatically transferred to an Internet portal, where they may be completed by the records from an electronic pedometer and continuous glucose monitor. All these data may then be displayed in various types of graphical outputs and are available to both the patient and the physician. The case report of a patient who has used the system for almost two years shows a significant improvement in metabolic compensation (a decrease in the mean HbA1c value by 18.6 mmol/mol as compared with the previous period).

Genetic variants associated with glycemic response to treatment with dipeptidylpeptidase 4 inhibitors.

Aim: We examined associations of eight SNPs in/near seven candidate genes with glycemic response to 6 month treatment with DPP4 inhibitors. Patients & methods: 206 patients with type 2 diabetes (116 men and 90 women) were treated with sitagliptin or vildagliptin (both 100 mg/day) in combination with metformin or metformin/sulphonylurea over 6 months, and the reduction in glycated hemoglobin (HbA1c) was measured. Results: Rs6923761 in GLP1R was significantly associated with a reduction in HbA1c (adjusted p = 0.006). Homozygotes for the minor A allele had smaller reduction in HbA1c by 0.4% (4 mmol/mol) than the G allele carriers (p = 0.016). Conclusion: The missense variant rs6923761 in the GLP1R gene was associated with a smaller glycemic response to 6 month gliptin therapy in diabetic patients of central European origin.

The impact of type 1 diabetes mellitus on male sexual functions and sex hormone levels.

Little is known about type 1 diabetes mellitus (T1DM) impact on the male sexual and reproductive functions. We aim to evaluate the influence of T1DM on male sexual function, quality of sexual life, and sex hormone levels. A total of 57 male patients aged 18 to 50 years (mean = 33) with T1DM (duration mean = 15 years) had a medical examination and completed a set of questionnaires - International Index of Erectile Function-5 (IIEF-5), Beck Depression Inventory (BDI) and Sexual quality of life questionnaire male (SQoL-M). The prevalence of erectile dysfunction was 28.1% (IIEF-5 ≤21). Patients without diabetic nephropathy had better erectile function (p = 0.008). Subjects with better glycemic control (HbA1c <65 mmol/mol) had also better erectile function (p = 0.041). At least 8.8% patients had retrograde ejaculation. Blood serum levels of sex hormones were determined and compared to laboratory reference values of healthy men. Total testosterone level was not significantly changed, sex hormone binding globulin was higher (p < 0.001) and its level correlated with daily insulin dose adjusted to body weight (p = 0.008). Free androgen index and calculated free testosterone were lower (p = 0.013; p < 0.001), estradiol was not significantly changed, LH was higher (p < 0.001), FSH was unchanged, and prolactin was higher (p < 0.001). Prostate-specific antigen (PSA) negatively correlated with HbA1c (p < 0.001). To conclude, we found significant changes in sexual functions and sex hormone blood concentrations that indicate impairment of sexual and reproductive functions in T1DM males.

Strategy and tactics of treatment of type 2 diabetes mellitus.

The results of randomized double-blind studies provide scientifically accurate data on the efficacy of antidiabetic drugs. With the widening understanding of heterogeneity of the group of patients with type 2 diabetes mellitus and the broadening possibilities of interventions available, a differentiated approach to therapy is now accentuated. From the perspective of pathophysiology, 8-10 different disorders have been described which contribute to the occurrence of hyperglycemia, but they cannot be quantified in common practice. However, it is possible to evaluate the amount of insulin secretion (C-peptide), the presence or severity of insulin resistance (triacylglycerols), glomerular filtration and, of course, patient compliance. The strategic goal of treatment of diabetes mellitus is to reduce the risk of late complications, both specific and non-specific (atherosclerotic), and if they arise, then slowing-down of their progression. All of this as a means of reducing mortality and improving quality of life. The tactics of therapy for type 2 diabetes mellitus must first of all be chosen individually. We bear in mind the general circumstances (life expectancy, comorbidities, age, compliance, social background, type of work) and specific characteristics of the current development of diabetes (the dominant nature of metabolic disorder, the level of preservation of insulin secretion or response to prandial stimulation, presence and progression of complications). A timely combination of 2 or more antidiabetic drugs targeting individual pathophysiological mechanisms can be considered useful.

How well we treat with insulin in the Czech Republic and in the Slovak Republic A summary of results and comments on the original Czech-Slovak DIAINFORM study.

Despite the continuously improving treatment options, many patients with type 1 (T1DM) and type 2 diabetes (T2DM) still do not achieve the recommended treatment goals. The article provides summary and commentary of the results of DIAINFORM study focused on the level of metabolic control in T1DM and T2DM patients treated with insulin in the Czech and Slovak Republics. The overall percentage of patients with HbA1c 3 mmol/mol in the T1DM group was 29.9 % and in the T2DM group was 33.4 %.

Ethanol and risk of hypoglycemia in patients with type 1 diabetes mellitus: a brief overview for clinical practice.

Alcoholic drinks are one of the risk factors for hypoglycemia. Ethanol inhibits gluconeogenesis, decreases a level of growth hormone and impairs hypoglycemia awareness. The risk of hypoglycemia while drinking alcohol can be reduced by parallel ingestion of food (saccharides). Some recommendations also mention the change of insulin doses.

Sexual Dysfunction in Women Treated for Type 1 Diabetes and the Impact of Coexisting Thyroid Disease.

INTRODUCTION: More sexual problems are reported among people treated for diabetes; however, this situation is less explored in women than in men. AIM: To analyze the presence and causal links of female sexual dysfunction (FSD) among Czech women treated for type 1 diabetes. METHODS: 40 women completed a national version of the Female Sexual Function Index (FSFI), Female Sexual Distress Scale-revised (FSDS-R), and Beck's Depression Inventory-II (BDI-II). A metabolic and endocrine analysis was done using blood samples. Data were statistically analyzed using SPSS v.24 and the R environment. MAIN OUTCOME MEASURES: Patient details (personal information, diabetes-related data, and sex history), sexual performance (the FSFI and FSDS-R scores), and level of depression (the BDI-II score) were measured. RESULTS: FSD was present in 58% of the participants (based on the FSFI score), and 38% women declared significant sexual distress (according to their FSDS-R score). Even though only 4 women fulfilled the criteria for depression, we observed a strong association between BDI-II and FSFI (for total FSFI score P = .012, ρ = -0.394) resp. FSDS-R scores (P < .001, ρ = 0.552). Although we were not able to establish a clear direct connection between FSD and metabolic control, BDI-II scores were closely correlated with glycosylated hemoglobin (P = .009, ρ = 0.407). The duration of diabetes (based on FSDS-R: P = .046) but neither age nor the presence of chronic diabetic microvascular complications was associated with a higher FSD occurrence. We also observed an association between FSD and the presence of autoimmune hypothyroidism, even when successfully treated (FSDS-R: P = .009; FSFI: P = .067). CONCLUSION: FSD is more common in women with type 1 diabetes than in healthy women, and coexisting thyroid autoimmune disease seems to exacerbate FSD. Women suffering from type 1 diabetes, and particularly those with additional endocrinopathies, should be actively screened for FSD. Stechova K, Mastikova L, Urbaniec K, et al.

Addition of Basal Insulin to Oral Antidiabetic Agents in Patients with Inadequately Controlled Type 2 Diabetes Leads to Improved HbA1c Levels: Metabolic Control, Frequency of Hypoglycemia, and Insulin Titration Analysis as Results of a Prospective Observational Study (BALI Study).

INTRODUCTION: Despite the continuously growing number of therapeutic options for patients with type 2 diabetes mellitus (T2DM), a large percentage of these individuals fail to achieve their glycated hemoglobin (HbA1c) target. The aim of this study was to determine the change in metabolic control in insulin-naïve T2DM patients inadequately controlled with oral antidiabetic drugs (OADs) at 6 months after initiating basal insulin treatment as add-on to existing OADs. METHODS: This was a non-interventional prospective study conducted from June 2013 to December 2014 in 137 centers in the Czech Republic under routine clinical practice conditions. Adult patients whose diabetes was uncontrolled on their current OAD treatment (HbA1c ≥ 53 mmol/mol; Diabetes Control and Complications Trial [DCCT]-HbA1c 7%) and whose physician had decided to initiate treatment on a basal insulin regimen were documented over a 6-month period beginning from the time of initiation of basal insulin treatment. RESULTS: Overall, 1426 T2DM patients were included in the study, of whom 53% were male. The mean age of the study population was 63.8 ± 10.1 years, mean body mass index was 31.5 ± 5.3 kg/m2, and mean duration of diabetes was 10.2 ± 5.3 years. At the 6-month follow-up, the target HbA1c level of 53 mmol/mol (DCCT < 7%) was achieved by 18% of patients. The mean HbA1c overall had decreased from 77.2 ± 15.1 mmol/mol (DCCT 9.21 ± 1.38%) at baseline to 63.2 ± 12.5 mmol/mol (DCCT 7.93 ± 1.14 %) at the 6-month follow-up. This difference was significant at p < 0.001. The largest mean reduction in HbA1c, i.e., 20.9 mmol/mol (DCCT 2.4 %) was observed in the group of patients with a baseline HbA1c of ≥ 9%. The mean daily basal insulin dose at 6 months was 18.8 ± 8.9 units. Symptomatic hypoglycemia was reported in 12.3% of patients, of those only one patient (0.1%) suffered from severe hypoglycemia. CONCLUSION: The addition of basal insulin to the therapeutic regimen of insulin-naïve T2DM on OAD treatment resulted in an improved metabolic control of diabetes after 6 months of treatment. However, most patients did not achieve their HbA1c target, probably also due to inadequate titration of basal insulin. FUNDING: Sanofi, Czech Republic.

Prevalence of Diabetes Mellitus among Roma Populations-A Systematic Review.

BACKGROUND: The aim of this study was to estimate the prevalence of diabetes mellitus in the Roma population and compare it to the prevalence in the Caucasian population. METHODS: Using the words "Roma", "Gypsies", "Romani", and "traveler" in combination with "diabetes, "metabolic syndrome", "cardiovascular disease" and "health status" we searched the MEDLINE, Pubmed and Scopus databases for articles in English that focused on the prevalence of diabetes mellitus among Roma populations published until December 2017. RESULTS: Five studies met the inclusion criteria. The results of four of them suggested a higher prevalence of diabetes among Romani compared to Caucasians but none of them reached the standards regarding representative samples and number of cases for a conclusive result. CONCLUSION: Although some of the existing studies suggest a substantial prevalence of diabetes among Roma populations and even a higher risk of developing diabetes for Roma persons compared to Caucasians, the number of published literature on this topic remains very low and insufficient in design and number of participants to draw any conclusions.

Current Level of Glycemic Control and Clinical Inertia in Subjects Using Insulin for the Treatment of Type 1 and Type 2 Diabetes in the Czech Republic and the Slovak Republic: Results of a Multinational, Multicenter, Observational Survey (DIAINFORM).

INTRODUCTION: The aim of the study was to determine the level of metabolic control in type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) patients in the Czech and Slovak Republics. METHODS: A non-interventional prospective (observational) study was conducted from January 2015 until April 2016 in routine clinical practice settings at 141 centers in the Czech and Slovak Republics. Data were analyzed from a total of 425 patients with T1DM and 1034 patients with T2DM, proportionally corresponding to the number of patients in both countries. The primary objective of the study was to determine the percentage of patients with HbA1c < 7% (53 mmol/mol). RESULTS: Patients with T1DM: In this group of patients (55.8% males, mean age 45.9 ± 14.83 years, BMI 25.8 ± 4.21 kg/m², diabetes duration 12.1 ± 9.44 years), 29.9% reached HbA1c levels < 53 mmol/mol. Patients with T2DM: In this group of patients (50.3% male, mean age 63.9 ± 9.65 years, BMI 31.0 ± 5.19 kg/m², diabetes duration 12.4 ± 7.47 years, duration of insulin therapy 5.8 ± 4.71 years), 33.4% reached HbA1c levels < 53 mmol/mol. CONCLUSION: The overall percentage of patients with HbA1c < 53 mmol/mol in the T1DM group was 29.9% and in the T2DM group was 33.4%. Despite an increasing number of treatment options, most patients still fail to reach the recommended HbA1c targets. FUNDING: Sanofi, Czech Republic.

Lessons Learned from Implementing a New Testing/Educational Tool for Patients Using an Insulin Pump.

BACKGROUND: To improve insulin pump therapy results, a special test for patients was devised. The model successfully used to achieve a license to operate different machines was followed. METHODS: The test (a practice and a full run, with a time limit) contained 42 questions, each with four optional choices, and could be answered online. Patients could familiarize themselves with the whole question pool first. Patients could repeat a full run attempt if they failed and were offered focused remedial education. The study group composed of adults, 46 females, and 54 males, all treated for type 1 diabetes, 38/100 newly introduced to insulin pump therapy. RESULTS: Eighty-five of 100 patients successfully completed their first full run attempt (80% or higher correct answers) and 3 of 100 on their second full run attempt; 12 of 100 patients were not able to succeed. The median of the test score was 2 mistakes (range 0-17 mistakes). The most problematic topics were diet and insulin regimens and their application. The crucial factor influencing the test score was the willingness to try practice run(s). Those who practiced had a significantly higher total test score with better results in 5 of 8 tested knowledge domains. Age and diabetes existing >15 years had an impact on the result, too. Both patients' and caregivers' opinions on the test were predominantly positive (or neutral). CONCLUSIONS: The type of test introduced is a good tool for checking a patient's theoretical knowledge and indirectly revealing a patient's level of motivation.

Analysis of Postprandial Glycemia in Relation to Metabolic Compensation and Other Observed Parameters of Outpatients with Type 2 Diabetes Mellitus in the Czech Republic.

INTRODUCTION: The goal of the study was to determine the level of metabolic compensation expressed by glycosylated hemoglobin, fasting plasma glucose, and postprandial glucose as determined after a standardized breakfast; further, to evaluate interrelationships between the studied parameters and postprandial glucose levels. METHODS: The study included 1055 patients with type 2 diabetes mellitus. Their fasting plasma glucose and postprandial glucose were measured before and after a standardized breakfast. Attending diabetologists completed a uniform questionnaire that included demographic data, type of antidiabetic treatment, duration of diabetes, latest glycosylated hemoglobin value, presence of dyslipidemia, and organic complications. RESULTS: Glycosylated hemoglobin < 53 mmol/mol was achieved in 363 (34.2%), postprandial glucose < 7.5 mmol/l in 211 (19.9%), and fasting plasma glucose < 6 mmol/l in 251 (23.7%) patients. Excellent metabolic compensation, indicated by all the above mentioned glycosylated hemoglobin, fasting plasma glucose, and postprandial glucose values simultaneously, was achieved in only 71 (6.7%) patients. Comparable to fasting plasma glucose and postprandial glucose values, correlation with glycosylated hemoglobin levels is statistically significant; however, there is no difference at different glycosylated hemoglobin levels. There was a significant correlation between dyslipidemia and postprandial glycemia (p = 0.013). CONCLUSION: The objective of care for patients with diabetes mellitus is to improve their long-term metabolic compensation; to that end, both fasting plasma glucose and postprandial glucose deserve equal attention.

Cost-Effectiveness of IDegLira Versus Insulin Intensification Regimens for the Treatment of Adults with Type 2 Diabetes in the Czech Republic.

INTRODUCTION: The aim of this study was to evaluate the long-term cost-effectiveness of the insulin degludec/liraglutide combination (IDegLira) versus basal insulin intensification strategies for patients with type 2 diabetes mellitus (T2DM) not optimally controlled on basal insulin in the Czech Republic. METHODS: Cost-effectiveness was evaluated using the QuintilesIMS Health CORE Diabetes model, an interactive internet-based model that simulates clinical outcomes and costs for cohorts of patients with diabetes. The analysis was conducted from the perspective of the Czech Republic public payer. Sensitivity analyses were conducted to explore the sensitivity of the model to plausible variations in key parameters. RESULTS: The use of IDegLira was associated with an improvement in the quality-adjusted life expectancy of 0.31 quality-adjusted life-years (QALYs), at an additional cost of Czech Koruna (CZK) 107,829 over a patient's lifetime compared with basal-bolus therapy, generating an incremental cost-effectiveness ratio (ICER) of CZK 345,052 per QALY gained. In a scenario analysis, IDegLira was associated with an ICER of CZK 693,763 per QALY gained compared to basal insulin + glucagon-like peptide-1 receptor agonist (GLP-1 RA). The ICERs are below the generally accepted willingness-to-pay threshold (CZK 1,100,000/QALY gained at the time of this analysis). CONCLUSIONS: Results from this evaluation suggest that IDegLira is a cost-effective treatment option compared with basal-bolus therapy and basal insulin + GLP-1 RA for patients with T2DM in the Czech Republic whose diabetes is not optimally controlled with basal insulin.

KCNQ1 gene polymorphism is associated with glycaemic response to treatment with DPP-4 inhibitors.

AIMS: Only afew gene variants were associated with the response to dipeptidylpeptidase-4 inhibitors (DPP4I). KCNQ1 gene variants were previously related both to type 2 diabetes (T2D) and incretin effect. We hypothesized that T2D related KCNQ1 variants would be associated with smaller glucose-lowering effect of DDP4I. METHODS: We performed a retrospective study in 137 Caucasian subjects with T2D who were followed for 6months after initiation of DPP4I treatment. Genotyping for KCNQ1 rs163184 and rs151290 was performed using PCR-HRMA and PCR-RFLP methods, respectively. The main clinical outcome was reduction in HbA1c (ΔHbA1c) after 6-month DPP4I treatment. RESULTS: KCNQ1 rs163184 T>G variant was associated with the response to DPP4I treatment in genetic additive model (ß=-0.30, p=0.022). For each G allele in the rs163184 genotype, we observed a 0.3% (3.3mmol/mol) less reduction in HbA1c during treatment with a DPP4I. Both the GG homozygotes and G-allele carriers had significantly smaller HbA1c reduction in comparison with the TT homozygotes. CONCLUSIONS: KCNQ1 rs163184 T>G variant was associated with a reduced glycaemic response to DPP4I. The difference of 0.6% (6.5mmol/mol) in HbA1c reduction between the TT and GG homozygotes might be of clinical significance if replicated in further studies.

Early urinary biomarkers of diabetic nephropathy in type 1 diabetes mellitus show involvement of kallikrein-kinin system.

BACKGROUND: Additional urinary biomarkers for diabetic nephropathy (DN) are needed, providing early and reliable diagnosis and new insights into its mechanisms. Rigorous selection criteria and homogeneous study population may improve reproducibility of the proteomic approach. METHODS: Long-term type 1 diabetes patients without metabolic comorbidities were included, 11 with sustained microalbuminuria (MA) and 14 without MA (nMA). Morning urine proteins were precipitated and resolved by 2D electrophoresis. Principal component analysis (PCA) and Projection to latent structures discriminatory analysis (PLS-DA) were adopted to assess general data validity, to pick protein fractions for identification with mass spectrometry (MS), and to test predictive value of the resulting model. RESULTS: Proteins (n = 113) detected in more than 90% patients were considered representative. Unsupervised PCA showed excellent natural data clustering without outliers. Protein spots reaching Variable Importance in Projection score above 1 in PLS (n = 42) were subjected to MS, yielding 33 positive identifications. The PLS model rebuilt with these proteins achieved accurate classification of all patients (R2X = 0.553, R2Y = 0.953, Q2 = 0.947). Thus, multiple earlier recognized biomarkers of DN were confirmed and several putative new biomarkers suggested. Among them, the highest significance was met in kininogen-1. Its activation products detected in nMA patients exceeded by an order of magnitude the amount found in MA patients. CONCLUSIONS: Reducing metabolic complexity of the diseased and control groups by meticulous patients' selection allows to focus the biomarker search in DN. Suggested new biomarkers, particularly kininogen fragments, exhibit the highest degree of correlation with MA and substantiate validation in larger and more varied cohorts.

[Promising molecules for treatment of hyperglycemia in patients with type 2 diabetes]. / Perspektivní molekuly pro lécbu hyperglykemie u pacientu s diabetem 2. typu.

New antidiabetic drugs are being developed today that expand the range of pharmacological intervention, in particular for patients with type 2 diabetes (imeglimin, semaglutide, dulaglutide, FGF 21 analogue). At the same time innovations take place that "better" the well-proven molecules, they offer new application forms we have no experience of diabetology (osmotic pump for exenatide, faster acting insulin aspart). New properties are brought by just the change of concentration (insulin glargine in a concentration of 300 U/ml), unexpected positive results are also brought by new fixed-ratio combinations of antidiabetics (fixed-ratio combination of insulin degludec and liraglutide, fixed-ratio combination of insulin glargine and lixisenatide). Also results of clinical studies appear that concern molecules already in use which facilitate the formulation of new recommendations regarding treatment type 2 diabetes.Key words: type 2 diabetes mellitus - dulaglutide - FGF 21 - imeglimin - insulin aspart - insulin degludek - insulin glargine - ITCA 650 - liraglutide - national information diabetes system - semaglutide.

[The SPACE project (Stav Pacientu Akceptovaných diabetologem Cestou Exportu/The Health Records of Patients Accepted by a Diabetologist by way of Export)]. / Projekt SPACE (Stav Pacientu Akceptovaných diabetologem Cestou Exportu).

INTRODUCTION: A structured care of patients with diabetes is in place in the Czech Republic and the majority of patients are followed up by a diabetologist in outpatient diabetes units. The SPACE project (The Health Records of Patients Accepted by a Diabetologist by way of Export) was initiated to address the lack of the data which would allow for objective evaluation of how the cooperation in the care of patients with diabetes works in the real-life health care practice in the Czech Republic. GOAL: Gaining the description of anthropometric parameters, presence of complications, the chosen therapy and metabolic state of patients registered for diabetes specialist care. Secondary goals involved identification of the average duration of diabetes at the first patient visit to the outpatient diabetes clinic, prevalence of diabetes-related complications on the registration for diabetes care, the structure of pharmacological therapy for diabetes, hypertension, hyperlipoproteinemia. METHODOLOGY: Retrospective collection of data for the first 20-25 patients, who were consecutively registered in diabetes outpatient clinics from 1 January 2015 onwards. RESULTS: 778 complete questionnaires were included in the analysis. The greatest number of patients were referred by the general practitioner (64.5 %). Over 55 % of the patients were aged 50-69, less than 10 % were up to 40 years of age. 95.6 % of all cases involved type 2 diabetes mellitus. In almost 65 % of the cases duration of diabetes before registration for diabetes care is up to 2 years. There were 433 late complications recorded in 272 patients of the total number of 778 patients. 506 patients (65 %) had no late complications. Three most frequently occurring complications were ischemic heart disease (18.6 %), diabetic neuropathy (7.8 %) and stroke (5.5 %). The analysis of pharmacotherapy shows a significant increase in the use of the followed drugs after visiting a diabetologist (74.9 % before the diabetes visit and 96.7 % after the visit). Antidiabetic drugs or insulin were taken by 48.3 % of patients before the diabetologist visit, and they were taken by 92.5 % of patients after the first diabetologist visit.Key words: diabetes mellitus - epidemiology of diabetes mellitus complications - glycated hemoglobin - diabetes mellitus therapy.
