Introduction: The main goal of the diabetes mellitus type 1 (DM type 1) therapy is the achievement of the best compensation of this disease. One of the tools to attain this compensation is the correctly carried out self-monitoring, from which can be the right dose of the Insulin derived. To estimate the correct dose of the Insulin is the essential knowledge of the actual dietary records, especially the amount of the carbohydrates. The thorough dietary record is in this case another tool how to significantly improve the compensation of DM type 1. Objective: The main objective of this thesis was the description of the influence of the dietary record for the compensation of DM type 1. As the evaluating parameters were set the value of HbA1c before-and-after the observation and the glycemia variability during the observation. The observation had been provided during one month where in the beginning of the observation all patients took part in the educative stay. Methods: The examined sample included in total 34 persons, but 2 of them were excluded for health reasons. The final examined sample was consist of 32 persons, out of them 18 females and 14 males, which suffer from DM type 1. The average age of these patients was 36,6 years ± 12,6, where the average lasting of DM type 1 was 14,9 years ± 9,9. In...

The main objective of this study was research on biomarkers used in both diagnosis and therapy of diabetic complications. The main focus of our work came to be on one of these biomarkers - glycemic variability (GV). High GV is linked with more frequent occurance of hypoglycemia. There are even indications it might contribute to development of diabetic complications. With modern technology - continuous glucose monitoring (CGM), we are now able to reliably describe, calculate and reduce GV. So far it is unclear whether increased GV can contribute to the development of microvascular complications (MVC) in type 1 diabetes (T1D). Studies published so far have assessed GV primarily from routine self-monitoring of blood glucose (SMBG) using glucometers. In the light of this uncertaity, the first part of this work compares GV calculated from CGM with the presence of MVC in T1D patients. GV calculated from CGM, but not from SMBG, proved to be significantly higher in T1D patients with MVC, even though there was no significant difference in glycated hemoglobin (HbA1c). This finding supports the hypothesis that higher GV is related to higher risk of MVC and that HbA1c does not describe diabetes control completely. Moreover, it was shown that GV calculated from SMBG is insufficient. There is still no fully...

Introduction: Physical activity should be part of our everyday life. However, for people with Type 1 Diabetes Mellitus it is the most common cause of hypoglycemia. To control diabetes in the right way, it is therefore necessary to follow certain rules and recommendations that help preventing hypoglycemia while the physical activity remains beneficial at the same time. Aim of the work: The main aim of this study is to clarify the influence of physical activity in connection to long-term control of Type 1 Diabetes Mellitus. Methods: 102 respondents with diagnosed Type 1 Diabetes Mellitus in the age of 19-69 years participated in a quantitative analysis. This research was conducted in a form of multicentric examination at two independent medical centers. The data collection was done through questionnaires focused on physical activity and daily regime. The data from questionnaires were then compared to the values of glycated hemoglobin (HbA1C), HDL cholesterol and the total daily dose of insulin of certain patients. For statistical evaluation, analytical tools of Microsoft Office program were used (F-test and t-test). Results: We found correlation between HbA1C values in patients physically active for less than 2 hours/week compared to those who are physically active for more than 2 hours/week (62,72...

Title: Mountain tourism for diabetics with an insulin pump Objectives: The aim of this study is to find out whether it is suitable for patients with type 1 diabetes mellitus treated with an insulin pump to undergo physical activity in the form of mountain tourism, as the more intense physical aktivity affects blood glucose levels and whether patients are able to work with advanced insulin pump functions. Methods: The work is conceived as an observational study of the Medtronic educational project. One day mountain hike trip of a distance about 30 km was attended by 40 patients (men and women) with diabetes aged 15-25 years. Non-invasive methods were used. The data was obtained by monitoring insulin pump probes, glucometers and continuous monitoring, which were further evaluated using the CareLink Pro software. Results: Physical activity in the form of mountain tourism is suitable for patients with DM1 treated on an insulin pump. 80% of the probands did not have a risk status of hypoglycaemia, and even though the determined normoglycemia for research was performed by a larger number of adults as opposed to children, this FA has a demonstrable effect on blood glucose levels. It also brings positive benefits for patients because they learn how to work better with advanced insulin pump functions....

This thesis, entitled The Specific Needs of a Child with Type 1 Diabetes Mellitus in Primary School, is divided into two main parts. The theoretical part deals with the disease of diabetes mellitus, mainly type 1 diabetes mellitus and the specifics of childhood diabetes. In the practical part I focus on identifying the specific needs of children with type 1 diabetes mellitus attending the first level of primary school. Research information was obtained through interviews with parents of these children. The aim of the research was also to determine the level of satisfaction of parents with the schools' approach and whether and what they would like to change about the schools' approach. According to the responses, all school staff should know that a child is diabetic and be able to help them with hypoglycaemia. The child should be able to tell their classmates about the illness, respond to glycaemia at any time and contact parents if necessary. A negative experience associated with diabetes in the school environment was reported by 6 out of 15 children. In contrast, the same number of parents were satisfied with the approach and found nothing they wished to change. Parents would like teachers to be more empathetic and better educated. As a didactic output, an educational lecture was developed for...

We aimed to evaluate the endothelial function by combining RHI measurements and specific biochemical markers in the children with possible risk of premature manifestation of atherosclerosis and in the control group of healthy children. In all, 124 children (of which 106 patients divided into five groups according to diagnosis - type 1 diabetes mellitus, Crohn's disease, cystic fibrosis, familial hypercholesterolemia and acute lymphoblastic leukemia and 18 healthy controls) were enrolled in the study. During the study, we measured RHI using a new plethysmographic method and further evaluated biochemical markers of endothelial dysfunction (ADMA, E-selectin, hsCRP and VCAM) and lipidogram in individual groups of children. The primary objective of our study was the determination of RHI and biochemical parameters in healthy subjects and in selected risk groups of children (type 1 diabetes mellitus, Crohn's disease, cystic fibrosis, familial hypercholesterolemia and children after successful treatment of acute lymphoblastic leukemia). At the same time, we compared patients from individual groups with the control group. We found significantly elevated RHI values in groups of children with type 1 diabetes, Crohn's disease, cystic fibrosis, and children after successful treatment of acute lymphoblastic leukemia....

During treatment of diabetes mellitus by immunointervention or transplantation, it is necessary to monitor the markers of immune destruction or rejection of surviving insulin producing cells. An aim of this thesis is to improve the possibilities of following autoimmunity and to detect the survival of transplanted pancreatic islet in vivo. Partial aims included vitality testing of isolated islets for transplantation by measurement of respiration activity, observing the process of in vitro labeling of isolated islets with superparamagnetic iron oxide (SPIO) contrast agent for subsequent magnetic resonance imaging (MRI) of islets and observing SPIO particles transport after transplantation. We also studied a new dual paramagnetic contrast agent combined with fluorescein intended for identification of the MRI contrast agent in samples for histology. Further, we assessed autoimmune reaction by evaluation of cytokine response to specific stimulation with auto-antigens. We tried to affect beta-cells destruction by polyclonal anti- thymocyte antibodies in a mouse experimental model. A new method of the islet respiration measurement correlated with other methods of islet quality testing and it was suggested as a diagnostic test before clinical transplantation. Results obtained studying the intercellular...

Type 1 diabetes (T1D) is an autoimmune disease with multifactorial aetiology that involves an attack of self-reactive cytotoxic CD8 lymphocytes on insulin-producing beta cells in the pancreas. In the T1D pathophysiology, both innate and adaptive immunity mechanisms cooperate in the development of inflammation leading to autoimmune destruction. Autoreactive T lymphocytes are the canonical destructors of the beta cells, and B cells produce autoantibodies; the innate immunity cells are considered the initiators of the pathological autoimmune reaction by promoting T and B cell activation. Here, we provide evidence of both innate and adaptive immunity cell types dysregulation in patients with T1D, and that these changes occur before the onset of the disease. The changes in T regulatory lymphocytes (Tregs) and B cell subpopulations occur already in asymptomatic T1D first-degree relatives. During the first year after the onset of the disease, there is a gradual decrease in the neutrophil numbers in the periphery, which probably infiltrate the pancreas. We have focused more closely on the innate immunity dysregulation and its contribution to T1D pathogenesis. Initially, we describe that neutrophil products called neutrophil extracellular traps (NETs) are able to induce IFNγ-producing T cells through...

Introduction: Relation of diabetes mellitus (DM) to the diabetic keratopathy and various stages of corneal nerve fiber damage has been well accepted. A possible association between changes in the cornea of diabetic patients and diabetic retinopathy (DR), DM duration, and age at the time of DM diagnosis were evaluated. Neuropathies are among the most common long-term complications of diabetes mellitus. Good glycemic control is essential in prevention of this complication. DM patients with similar mean glucose levels or glycated hemoglobin (HbA1c) levels often exhibit differences in evaluation of diabetic complications. One reason for these differences may be the differences in glucose variability. DM patients with similar mean glucose levels or HbA1c levels often exhibit differences in glucose variability Hypothesis: Diabetes mellitus damages the subbasal nerve fibers of the corneal and affects the density of epithelial, endothelial and stromal cells. Corneal changes in patients with DM are dependent on the degree of diabetic retinopathy (DR), age at diagnosis, duration of DM, and compensation parameters. Purpose: To compare changes in cell density in individual layers of cornea and status of subbasal nerve fibers in patients with type 1 DM (DM 1) and in healthy subjects. To evaluate the dependence...
