Summary. Mitral valve prolapse is a significant cardiovascular risk factor in young adults. Its combination with type 1 diabetes mellitus can influence the nature and development of the disease. Objective – a comparative analysis of free and peptide-bound oxyproline levels and basic echocardiographic parameters (ECP) in patients with mitral valve prolapse, type 1 diabetes and their combination. Materials and methods – 93 people aged 19–33 years were examined, including 24 people with mitral valve prolapse without concomitant pathology; 33 patients with mitral valve prolapse and type 1 diabetes; 36 patients with type 1 diabetes without mitral valve prolapse. Results. The level of free and peptide-bound oxyproline in blood serum and their ratio were assessed as a marker of collagen metabolism. The levels of free oxyproline were significantly higher only for the group of MVP patients with type 1 diabetes (p < 0.05) compared to the control group. Severity of destructive processes was demonstrated by a high level of peptide-bound oxyproline, both in combined pathology compared with control group, and compared with groups of patients with monomorbid diabetes and MVP (p < 0.05). In patients with mitral valve prolapse and type 1 diabetes for more than 10 years in anamnesis were found significant differences in the echocardiography parameters (ventricular septum thickness, posterior wall of the left ventricle thickness) compared with the subgroup of patients with less than 10 years of type 1 diabetes in anamnesis and the group with isolated mitral valve prolapse. Conclusions. The data obtained indicate an aggravation in collagen metabolism disorders in patients with mitral valve prolapse depending on the duration of type 1 diabetes, and demonstrate the effect of carbohydrate metabolism disorders on the risk of developing connective tissue degradation of the heart valve apparatus.

In order to study the influence of the main fibroblast growth factor on the indicators of the state of the main substance of the extracellular matrix, a comparative analysis of their levels in the blood serum was carried out in persons with mitral valve prolapse and type 1 diabetes mellitus. The data obtained showed that the highest level of FGF-2 was observed in patients with a combination of MVP and type 1 diabetes mellitus compared with isolated MVP and diabetes, the control group (p <0.01) Level II of the GAG ​​fraction, which is represented in the main substance of the extracellular the matrix of the heart valve apparatus was also the highest in comorbid pathology, significantly differing from the control group (p <0.05). The level of GAG fraction III was higher among diabetic patients, regardless of the presence or absence of MVP, which is associated with the localization of this GAG fraction in the basement membranes of blood vessels and may be one of the elements of the pathogenesis of diabetic angiopathy

The aim. The aim of the study was to conduct a comparative analysis of fibroblast growth factor-2, the total content and fractions of sulfated glycosoaminoglycans as well as free and peptide-bounding oxyproline as the markers of connective tissue metabolism in young patients with mitral valve prolapse, type 1 diabetes mellitus and the combination of both indications. Materials and methods. 93 patients between 19 and 33 years old with either mitral valve prolapse, or type 1 diabetes or the combination of both indications were examined. Group 1 was represented by 36 patients with the monomorbid type 1 diabetes mellitus. Group 2 consisted of 33 patients with type 1 diabetes mellitus and mitral valve prolapse. The comparison group included 24 people with diagnosed mitral valve prolapse. The concentration of fibroblast growth factor-2 in blood plasma was determined by the enzyme immunoassay using a Quantikine reagent kit (Human FGF basic Immunoassay), manufactured by R&D Systems, Inc. (USA) and expressed in pg/ml. The total content and fractions of glycosaminoglycans in blood serum were determined by the method of N. G. Stern et al. and expressed in units of optical density. The level of free and peptide-bounding oxyproline in blood serum were determined by the method of P. N. Sharaev and expressed in µmol/L. Results. Fibroblast growth factor-2 was higher in group 2, where it was 23.7±0.25 pg/ml compared to the control group – 14.20±0.22 pg/ml (p <0.01). There was also a significant difference in the levels of fibroblast growth factor-2 between groups 1 where it equaled 15.33±0.24 pg/ml and 2 – 23.71±0.25 pg/ml (p<0.01). The total content of glycosaminoglycans in comparison with the control group, where it was equal to 9.7±0.62 odu, was higher in all groups of patients: in group 1 it was 12.07±1.04 odu, in the comparison group it was 11.75±0.83 odu, in the group with the combined pathology it was 13.32±1.59 odu (p<0.05). The values of glycosaminoglycans II fraction, were higher in group 2 – 4.96±0.59 odu. The level of peptide-bound oxyproline, just as the level of free oxyproline, significantly increased in patients with comorbid pathology in group 2, compared to the control group: 16.06±1.54 µmol/l versus 8.7±0.81 µmol/l (p<0.01) respectively. Conclusions. The values of fibroblast growth factor-2, glycosaminoglycans II fraction, free and peptide-bound oxyproline were significantly higher in patients with diabetes mellitus and mitral valve prolapse in comparison with the control group. Fibroblast growth factor-2 was higher in patients with comorbid pathology compared to the monomorbid diabetes patients.

The aim is to study morphofunctional structure of NALT (nasal associated lymphoid tissue) and visceral lymph nodes of rats with experimental type 1 diabetes mellitus (DM-1) and to define the effectiveness of the treatment with herbal drug “Imupret”. Materials and methods: The experiment involved 20 animals, divided into 4 groups: the 1st group was the control group of healthy rats, the 2nd group was the control group subject to prophylactic treatment with “Imupret, the 3rd group included rats with experimental diabetes, and the 4th group included rats with experimental diabetes subject to treatment with “Imupret. Functional changes in immune organs were evaluated by the results of morphometric analysis; morphological pattern was evaluated by histostructural changes. Results. The research revealed that under conditions of diabetes mellitus type 1, the volume, area and density of the lymphoid tissue decreased, and only its "fine" cell was detected. The paper demonstrates the development of relative immune deficiency in immunocompetent organs in rats with diabetes mellitus type 1. The use of drug "Imupret" demonstrated its immunomodulatory function, which is especially important in terms of immunosuppression in patient with DM-1. Conclusion. The received results are of a great clinical significance, and show the necessity of early prevention and treatment of immunity disorders under conditions of diabetes mellitus type 1.

Aim. To evaluate the effect of changes occuring in the organism in diabetes mellitus type 1 on the state of bone mineral density and its metabolism parameters; to determine the changes in serum markers of bone remodeling and bone mineral density in this disease. Methods. Bone mineral density (by dual-energy X-ray absorptiometry) and serum markers of bone remodeling (total alkaline phosphatase activity, level of aminoterminal propeptide of type 1 procollagen and C-terminal telopeptide) were examined in 98 patients with diabetes mellitus type 1 and in the control group consisting of 82 subjects. Results. The average concentration of C-terminal telopeptide in the blood serum of patients with type 1 diabetes (0.525±0.03 ng/ml) was significantly higher in comparison to the control group (0.424±0.02 ng/ml; p <0.01). Proximal femoral T-score in type 1 diabetes was significantly lower than the average value in the control group: -1.44±0.15 and -0.49±0.17 (p <0.001). In the femoral neck it was -1.68±0.14 and -0.64±0.18 (p <0.001), in LI-IV zone -2.04±0.16 and -0.73±0.19, respectively (p <0.001). Moderate negative significant correlation was found between T-score (LI-IV) and level of C-terminal telopeptide (r=-0.431, p=0.000). Conclusion. In patients with diabetes mellitus osteopenia is a relatively frequent complication, but bone loss increases with duration and decompensation of the disease; evaluation of bone mineral density and C-terminal telopeptide level (bone resorption marker) promotes detection of bone metabolism abnormalities at any stage of the disease, especially in the long-term course of type 1 diabetes.

AbstractThe aim of the study was to determine the frequency and titers of anti-thyroid peroxidase (Anti-TPO), anti-thyroglobulin (Anti-TG), and anti-glutamic acid decarboxylase (Anti-GAD) antibodies in Turkish patients with type 1 diabetes mellitus (DM), and to compare the frequency of anti-TPO and anti-TG titers in the presence or absence of anti-GAD. A total of 104 patients including 56 males and 48 females with type 1 DM and their age-, gender-, and body mass index-matched control group, including 31 males and 27 females, 58 cases in total with an age range of 15-50 years, were recruited into this study. In patients with type 1 DM, positive anti-GAD was detected in 30.8% (n=32). In patients with positive anti-GAD, rate of positive anti-TPO was 37.5%; however, in patients with negative anti-GAD, the rate of positive anti-TPO was 9.7% and the difference was statistically significant (p=0.001). In patients with positive anti-GAD, the rate of positive anti-TG was 18.8%. In patients with negative anti-GAD, the rate of positive anti-TG was 2.8%, and the difference between them was statistically significant (p=0.005). In patients with positive and negative anti-GAD, rates of both positive anti-TPO and anti-TG were 15.6% and 1.4%, respectively, with the difference showing statistical significance (p=0.004). Thyroid autoimmunity in type 1 DM patients with positive anti-GAD was apparently higher; therefore, these patients should be followed more frequently and carefully.

Background. The ELKa system is composed of computer software, with a database of nutrients, and a dedicated USB kitchen scale. It was designed to automatize the everyday calculations of food exchanges and prandial insulin doses. Aim. To investigate the influence of the ELKa on metabolic control in children with type 1 diabetes mellitus (T1DM). Methods. A randomized, parallel, open-label clinical trial involved 106 patients aged <18 years with T1DM, HbA1C≤10%, undergoing intensive insulin therapy, allocated to the intervention group, who used the ELKa (n=53), or the control group (n=53), who used conventional calculation methods. Results. After the 26-week follow-up, the intention-to-treat analysis showed no differences to all endpoints. In per protocol analysis, 22/53 (41.5%) patients reporting ELKa usage for >50% of meals achieved lower HbA1C levels (P=0.002), lower basal insulin amounts (P=0.049), and lower intrasubject standard deviation of blood glucose levels (P=0.023) in comparison with the control. Moreover, in the intervention group, significant reduction of HbA1C level, by 0.55% point (P=0.002), was noted. No intergroup differences were found in the hypoglycemic episodes, BMI-SDS, bolus insulin dosage, and total daily insulin dosage. Conclusions. The ELKa system improves metabolic control in children with T1DM under regular usage. The trial is registered at ClinicalTrials.gov, number NCT02194517.

Background. It is well known that intramammary arterial calcifications diagnosed by mammography as a part of generalized diabetic macroangiopathy may be an indirect sign of diabetes mellitus. Hence, the aim of this study was to determine the incidence of intramammary arterial calcifications, the patient?s age when the calcifications occur, as well as to observe the influence of diabetic polineuropathy, type, and the duration of diabetes on the onset of calcifications, in comparison with nondiabetic women. Methods. Mammographic findings of 113 diabetic female patients (21 with type 1 diabetes and 92 with type 2), as well as of 208 nondiabetic women (the control group) were analyzed in the prospective study. The data about the type of diabetes, its duration, and polineuropathy were obtained using the questionnaire. Statistical differences were determined by Mann-Whitney test. Results. Intramammary arterial calcifications were identified in 33.3% of the women with type 1 diabetes, in 40.2% with type 2, and in 8.2% of the women from the control group, respectively. The differences comparing the women with type 1, as well as type 2 diabetes and the controls were statistically significant (p=0.0001). Women with intramammary arterial calcifications and type 1 diabetes were younger comparing to the control group (median age 52 years, comparing to 67 years of age, p=0.001), while there was no statistically significant difference in age between the women with calcifications and type 2 diabetes (61 years of age) in relation to the control group (p=0.176). The incidence of polineuropathy in diabetic women was higher in the group with intramammary arterial calcifications (52.3%) in comparison to the group without calcifications (26.1%), (p=0.005). The association between intramammary arterial calcifications and the duration of diabetes was not found. Conclusion. The obtained results supported the theory that intramammary arterial calcifications, detected by mammography could serve as markers of co-existing diabetes mellitus and therefore should be specified in radiologic report in case of their early development.
