The aim of this study was to estimate the effects of oral supplementation of alpha-lipoic acid (ALA) on contrast sensitivity (CS) in patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM). The study included 12 patients with T1DM aged43±12years, 48 patients with T2DM aged59±10years, and 20 control subjects aged33±8years. Patients from each studied group, including the control group, were randomly assigned to receive 300 mg of ALA orally once daily for 3 months. CS was evaluated with the Functional Acuity Contrast Test (FACT, Stereo Optical). In the group of patients with T1DM receiving ALA for 3 months CS remained stable and improved in those with T2DM. Reduction of CS in both T1DM and T2DM patients without alpha-lipoic acid supplementation was observed. In the control group on alpha-lipoic acid supplementation, CS improvement was noticed at one spatial frequency. Changes in the CS were observed, despite stable visual acuity and eye fundus image in all studied subjects. Our study demonstrated that oral administration of alpha-lipoic acid had influence on CS in both T1DM and T2DM patients.

Objective: Relevance of cardiac autonomic neuropathy has not been fully recognized and there is no standardized treatment protocol.Aim: To evaluate the effects of alpha-lipoic acid on the beat-to-beat vectorcardiographic parameters, namely spatial QRS-T angle, QT dispersion (QTd) and corrected QT interval (QTc) in type 2 diabetes mellitus persons with cardiac autonomic neuropathy. Research designs and methods: Our study involved 33 persons with definite stage of cardiac autonomic neuropathy and diabetes mellitus type 2, which were assigned to each of two groups: one took standard antihyperglycaemic treatmen (n=15, control group) and the other (n=18) in addition to standard therapy - 600 mg of alpha-lipoic acid daily for three months. The analysis of vectorcardiographic parameters was performed. Results: It was found out that alpha-lipoic acid contributed to decrease of the vectorcardiographic parameters, namely QRS-T angle, QTd and QTc. Conclusions: The positive influences of alpha-lipoic acid suggest the usefulness of its prescription to type 2 diabetes mellitus persons with definite stage of cardiac autonomic neuropathy. The efficacy of alpha-lipoic acid is the result of its direct effect on the parameters of vectorcardiography.

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.

Abstract Erectile dysfunction (ED) is the inability to develop and/or maintain an erection that is sufficient for satisfactory sexual intercourse. The prevalence of erectile dysfunction in diabetic men is 28-75%, this percentage rising with patient’s age and duration of diabetes. The aim of the present study was to investigate erectile dysfunction and quality of life in patients with type 2 diabetes mellitus (T2DM) after treating them with transdermal testosterone or with alpha-lipoic acid. Materials and methods: The effect of a 12-week treatment with transdermal testosterone or alpha-lipoic acid on the erectile function and quality of life of 45 men with ED and T2DM was studied in a randomized, prospective, open clinical, comparative study. The parameters we measured in the patients were body weight and body mass index (BMI); the albumin, lipids, HbA1C, testosterone (T), sex hormone-binding globulin (SHBG), follicle stimulating hormone (FSH), luteinizing hormone (LH) and microalbuminuria levels; the International Index of Erectile Function (IIEF) and Health related quality of life (SF-36) questionnaires were completed to evaluate ED and quality of life before and after 12 weeks of treatment with alpha-lipoic acid (600 mg, parenterally, for 7 days, followed by 600 mg received per os) or with transdermal testosterone in a dose of 50 mg daily. Results: Testosterone treatment decreased BMI significantly (p < 0.01), increased testosterone concentrations (p < 0.01) and raised the SHBG levels (p < 0.05), improved the glycemic control and lipid profile (total cholesterol, p < 0.05; HDL cholesterol, p < 0.05; triglycerides, p < 0.05). The patients treated with alpha-lipoic acid had their BMI (p < 0.01), HbA1C (p < 0.01), total cholesterol (p < 0.01), HDL-cholesterol (p < 0.01) and triglycerides (p < 0.01) significantly reduced. The indicators for ED in both groups were also statistically significantly improved. There was improvement for all patients’ self-assessment score for “physical functioning” (p = 0.001), for “role limitations due to physical health” (p < 0.001) and for “general health perception” (p = 0.021). Conclusions: Transdermal testosterone and alpha-lipoic acid have a tangible beneficial effect on erectile dysfunction and on metabolic disorders in T2DM patients and can be used to treat such patients.

Abstract Objective. Significantly underdiagnosed, diabetes-associated cardiac autonomic neuropathy (CAN) causes a wide range of cardiac disorders that may cause life-threatening outcomes. This study investigated the effects of alpha-lipoic acid (ALA) on arterial stiffness and insulin resistance (IR) parameters in type 2 diabetes mellitus (T2D) patients and definite CAN. Methods. A total of 36 patients with T2D and a definite stage of CAN were recruited. This investigation was carried out on two separate arms: traditional hypoglycemic therapy (n=18, control) and ALA (n=18) 600 mg in film-coated tablets/q.d. in addition to traditional hypoglycemic therapy. The duration of the study was three months. Results. In subjects with T2D and definite stage of СAN, treatment with ALA resulted in a significant decrease of glucose, immunoreactive insulin concentration, and Homeostasis Model Assessment (HOMA)-IR (HOMA-IR) parameters; pulse wave velocity (PWV), aorta augmentation index (AIxao) during the active period of the day and decrease of PWV, AIxao, and brachial augmentation index during the passive period of the day compared with the results, obtained in the control group. Therefore, the administration of ALA to patients with T2D for three months promotes the improvement of glucose metabolism and arterial stiffness parameters. Conclusions. In patients with T2D and definite stage of СAN treatment with ALA improved HOMA-IR and arterial stiffness parameters. These findings can be of clinical significance for the complex treatment of diabetes-associated CAN.

Purpose. Determining the functional state of the outer and inner retina’s layers in patients with diabetes mellitus (DM) type 1 and 2 before the clinical manifestations and in the early stages of diabetic retinopathy (DR) using the methods of multifocal electroretinography (mfERG) and microperimetry (MP).Patients and methods. 91 patients were examined (182 eyes). The patients were divided into 4 groups: 1st — 23 people (46 eyes) with diabetes without DR (the duration of the disease is up to 2 years); 2nd — 22 people (44 eyes) with diabetes without DR (diabetes from 2 to 8 years); 3rd — 24 people (48 eyes) with NPDR on the background of diabetes; 4th — 22 people (44 eyes) of the control group (healthy eyes). In addition to the standard ophthalmologic examination, all patients were registered mfERG (FOK1) on the diagnostic equipment EP-1000 Multifocal (Tomey, Germany) and carried out MP using the device “MAIA” (CenterVue, Italy).Results. According to mfERG, it has been established that the components of mfERG, the biopotential density and the amplitude of P1, are most sensitive to diabetic changes. In groups with type 1 and type 2 diabetes, there is a significant decrease in the density of P1 in comparison with the control group (p < 0.005, Mann-Whitney test), as well as a decrease in the amplitude of P1 on almost all tested rings (p < 0.005). In all groups, there is an increase in the latency of P1 in the central ring (0–2.3°). According to MP data, it was found that patients with type 1 and type 2 diabetes showed a decrease in the average light sensitivity in comparison with the control group, however, our data are within the reference values, regardless of the presence or absence of clinical manifestations of PD.Conclusion. As a result of the study, early functional and morphological disorders of the neurosensory apparatus of the eye in diabetes were identified. It is proved that mfER and MP allow to detect violations at the preclinical stage of DR and are necessary studies for the dynamic control of the progression of DR.
