Hypoglycemia related to treatment of type 2 diabetes mellitus patients constantly represents a substantial problem. It is connected with higher mortality and lower quality of life, mostly displayed with elder patients. Therefore it is vital to revise the antidiabetic therapy regularly and to inquire for the associated risks. Nevertheless, elder patiens are often following the inadvisable treatment by sulphonylureas derivates, which represent the second most risky medication causing hypoglycemia after insulin. In our retrospective study we analysed the occurence of serious hypoglycemia, caused by any factor, with severe diabetics urgently hospitalised at The Department of Internal Medicine of Masaryk Hospital in Ústí nad Labem, in relation to the applied antidiabetic therapy. We suspected a negative influence of hypoglycemizing therapy (above all sulphonylureas) with the elderly patiens. In sum, we hospitalised 32 patients with type 2 diabetes mellitus (average age 76,5 ± 8,2 years), 18 of these using sulphonylureas (average age 77,4, with a relatively wide range from 65 to alarming 93 years). The average figure of estimated glomerular filtration rate (eGFR) was 0,745 (±0,293) ml/s/1,73m2. Moreover, the patients manifested polmorbidity - the average of comorbidities was 3,125, and even 3,5 with patiens on sulphonylureas. Following the arguments summarised above, we believe that hypoglycemic episodes are extremely dangerous especially for elder patients with T2DM, and from this point of view, the medication using sulphonylureas derivates seems to be inappropriate.

Background: It is not always easy to classify diabetes (DM) diagnosed in adults, with a significant group of patients initially classified and treated for type 2 diabetes mellitus (DM2T) presenting signs indicating the presence of autoimmune insulitis (AI), which is characteristic of type 1 diabetes mellitus (DM1T), or latent autoimmune diabetes mellitus in adults (LADA)., Goal: Identify the proportion of patients entered with DM2T who present AI signs, and the number of patients of that proportion, who at the same time present low insulin secretion, and what clinical and laboratory manifestations could be used to differentiate between these patients.Cohort and methods: A randomized clinical trial with a pre-determined set of assessed parameters for n = 625 patients, who were hospitalized during the first 6 months of 2016 at the National Endocrinology and Diabetology Institute (NEDU), Lubochna. Apart from the standard parameters, C-peptide (CP) and autoantibodies to glutamic acid decarboxylase (GADA) were examined for each patient. GADA positive (GADA+) patients were compared to GADA negative (GADA-) patients in the following parameters: gender, age, age at the time of dia-gnosing DM, duration of DM, HbA1c, incidence of hypoglycemia, lipidogram, fasting C-peptide levels, BMI, waist circumference, incidence of hypoglycemias, presence of microvascular and macrovascular complications, treatment of dia-betes and incidence of other endocrinopathies. GADA+ with low CP were subsequently compared to GADA+ patients with normal CP., Results: Of 625 patients originally classified and treated as DM2T, 13 % were GADA+. 31 % of them had low CP (< 0.2 nmol/l) and 28 % had CP levels within the intermediary range (0.2-0.4 nmol/l). Females made up a larger proportion of GADA+ patients, with a lower BMI, smaller waist circumference, lower CP, higher HDL cholesterol levels, a greater incidence of hypoglycemias and lower total daily dose of insulin. GADA+ patients with low CP differed from GADA+ patients with normal CP in higher HDL cholesterol levels, lower triglyceride levels and earlier need of insulin thera-py. The testing for GADA and CP levels with regard to the other relevant characteristics led to re-classification, or more precisely adding of DM1T/LADA (as the main, or parallel cause of DM) for 2.9 % of all the patients included and a clinically significant proportion of AI could be assumed in 6.1 % of the patients., Summary: The results of our study show that the pathogenesis of DM in patients initially diagnosed and registered with DM2T and with concurrent presence of GADA includes mechanisms characteristic of both DM2T (insulin resistance) and DM1T (autoimmune insulitis) acting in parallel, with different intensity, in differing proportions and time sequence as a fluid continuum, which also accounts for the differences between individual patients. The characteristics highlighting the presence and role of AI based on our results include high titre of GADA+, low CP levels, early need of insulin therapy, presence of thyroid disorder, higher HDL cholesterol levels and lower triglyceride levels. The characteristics highlighting the dominance of mechanisms characteristic of DM2T (insulin resistance) included higher BMI and waist circumference values, normal CP levels, low HDL cholesterol levels, higher triglyceride levels, higher blood pressure and borderline titre of GADA., Key Words: autoimmune diabetes mellitus - C-peptide - GADA - HDL-cholesterol - classification.

Islet transplantation (ITx) started in 2005 in IKEM as a potentially safer alternative to pancreas transplantation (PTx), which so far had represented the method of choice in type-1 diabetic patients with conservatively intractable hypoglycemia unawareness syndrome. The aim of the study was to compare these two methods with regard to severe hypoglycemia elimination and to frequency of complications.Up to November 2015 a total number of 48 patients underwent ITx. The results from 22 patients with hypoglycemia unawareness were statistically analyzed. The mean number of transplanted islet equivalents was 12,096 (6,93316,705) IEQ/kg administered percutaneously in local anesthesia under radiological control to the portal vein. 44 patients underwent PTx from 1996. We evaluated glycated hemoglobin(HbA1c), insulin dose, fasting and stimulated C-peptide, frequency of severe hypoglycemia and complications. Medians (interquartile range) were analyzed using the Wilcoxon signed-rank test.One and two years after ITx, HbA1c decreased, C-peptide became significantly positive, insulin dose and frequency of severe hypoglycemia decreased and 18 % of ITx recipients were temporarily insulin-independent. Bleeding was present in 41 % of patients. One year after PTx, 73 % of patients were insulin and hypoglycemia-free, after two years 68 % of patients were insulin and hypoglycemia-free; graftectomy occurred in 20 % of recipients.Both methods led to restoration of insulin secretion and severe hypoglycemia elimination. PTx made more recipients insulin-independent at the cost of serious complications.

Objective: Mild hypoglycaemia affects diabetes management, productivity and quality of life of patients. Data are scarce about the incidence of mild hypoglycaemia in daily life of type 2 diabetic patients treated with insulin analogues. The aim was to focus on the incidence of mild hypoglycaemia and its consequences in the international GAPP2 survey (Global Attitudes of Patient and Physicians) conducted also in the Czech Republic., Methods: The GAPP2 project - Global Attitudes of Patients and Physicians is an international cross-sectional study conducted online via Internet in a questionnaire form dedicated to type 2 diabetic patients treated with insulin analogues and physicians who treat these patients. The survey was realized in two steps including 17 countries. The first step was completed by six countries in 2012. The second step was terminated by additional eleven countries including the Czech Republic in 2014. The survey was designed to obtain data on some aspects of insulin therapy and persistent issues in daily practice from the views of patients and physicians. One part of survey was dedicated to mild hypoglycaemia occurring in treatment with insulin analogues. The incidence of mild hypoglycaemia and the reaction of patients and physicians on hypoglycaemia (including modification of therapy, self-monitoring) were investigated. Moreover, there was investigated the impact of mild hypoglycaemia on quality of life from the view of patients and physicians., Results: The results of the survey have shown that mild hypoglycaemia is common in patients with insulin analogues in the Czech Republic. In addition, patients in the Czech Republic are more afraid from hypoglycaemia and feel more limited in daily life in comparison to other countries in GAPP2 survey. Patients try to avoid nocturnal hypoglycaemia through reduction or omission of prescribed dose of insulin. Furthermore, research has observed that physicians are poorly informed by patients about incidence and severity of hypoglycaemia., Conclusion: The incidence of mild hypoglycaemia is in the Czech Republic as common as in other countries involved in the GAPP2 survey. However, the Czech patients are more afraid and this fact is often hidden before physicians. Increased fear of hypoglycaemia suggests inadequate education in terms of how to avoid and manage hypoglycaemia. Particular emphasis should be placed on nocturnal hypoglycaemia. Physicians should discuss more with patients about issue of hypoglycaemia. It is important to motivate patients to share the information with physicians about incidence and severity of hypoglycaemia.
