Background: In individuals with type 2 diabetes mellitus (T2DM) the presence of Cardiac autonomic neuropathy (CAN) increases the risk of severe hypoglycaemia, cardiac arrhythmias, silent myocardial ischemia and stroke. It is also associated with increased perioperative morbidity and mortality, even with minor surgeries in these patients. The present study was conducted to assess the prevalence of CAN in T2DM patients and to investigate any possible association between CAN and micro vascular complications.Methods: 102 T2DM patients between the age of 30 years and 70 years, who attended outpatient department of Institute of Diabetology, Rajiv Gandhi Government General Hospital and Madras Medical College, Chennai, Tamil Nadu were included. All the selected patients underwent laboratory investigations, biothesiometry, fundus examination, and CAN assessment by CANS analyser.Results: A slight female preponderance was noted in the study, though it was statistically insignificant. Out of 102 patients, prevalence of CAN dysfunction was found in 82 (80.39%) of T2DM patients. No significant association of CAN was noted with duration of diabetes (p=0.772), HbA1c (p=0.827) and nephropathy (p=0.524). However, peripheral neuropathy (p=0.006) and retinopathy (p=0.03) were found to be significantly associated with CAN in T2DM patients.Conclusions: Prevalence of CAN in asymptomatic South Indian T2DM population was found to be 80.39%, with equal sex distribution and was most common in the 51- 60 years age group. Diabetic neuropathy and retinopathy were the most significant microvascular complications predictive of the incidence of CAN in T2DM patients.

Introduction. Currently, there is no unified treatment algorithm of cardiac autonomic neuropathy (CAN) in patients with type 2 diabetes mellitus (T2DM). The aim of the study was to investigate the effects of simvastatin (SIM) and -3 polyunsaturated fatty acids (-3 PUFAs) on blood lipid profile and insulin resistance (IR) in patients with type 2 diabetes mellitus and definite cardiac autonomic neuropathy. Materials and methods. The study involved 72 patients with T2DM and definite CAN. Patients were divided into four groups: 1st - received standard hypoglycemic therapy - control (n = 15); 2nd (n = 22) – in addition simvastatin (SIM) 20.0 mg/q.d.; 3rd (n = 18) - in addition 1 capsule/q.d. of the ω-3 PUFAs; 4th (n = 17) - in addition SIM 10.0 mg/q.d and 1 capsule/q.d of the ω-3 PUFAs for three months. The concentration of glucose, glycated hemoglobin A1c, immunoreactive insulin (IRI), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG) in the blood were determined. Homeostasis model assessment IR (HOMA-IR), atherogenic coefficient (AC), TG/LDL-C, TG/TC, TG/LDL-C and TG and glucose index (TyG) were calculated. Results. Prescription of SIM was accompanied by a statistically significant decrease in TC, LDL-C, TG concentrations. In parallel, SIM induced a decrease of AC, TG/HDL-C, increase in HDL-C, and does not affect the IRI, HOMA-IR, TG/LDL-C, TG/TC, TC/LDL-C/HDL-C, TyG. The use of ω-3 PUFAs has contributed to a significant reduction in TG, AC, TG/LDL-C, TG/TC, TG/HDL-C, TyG index, increase in HDL-C, and was not accompanied by changes in IRI content, HOMA-IR, TC, LDL-C, and TC/LDL-C/HDL-C. The combined prescription of SIM and -3 PUFAs was accompanied by more pronounced, statistically significant changes in the blood lipid spectrum, as well as a decrease in the IRI and HOMA-IR. Conclusions. Obtained results justify the appropriateness of combined simvastatin and -3 polyunsaturated fatty acids prescription to patients with type 2 diabetes mellitus and definite cardiac autonomic neuropathy. Keywords: diabetes mellitus, cardiac autonomic neuropathy, treatment.

Acute cerebrovascular accidents remain an urgent problem in neurology. Heterogeneous pathologies accompanying stroke determine its course and development of complications. Such pathologies require early remodeling during the rehabilitation process. Understaging the symptoms of cardiac autonomic neuropathy (CAN) associated with type 2 diabetes mellitus (DM 2) worsens the patient prognosis after an ischemic stroke. The aim of the paper is to study the manifestations of cardiac autonomic neuropathy in patients with ischemic stroke associated with type 2 diabetes mellitus and to assess their dynamics during verticalization. Materials and Methods. The study involved 60 patients of both sexes (aged 45–75) with acute ischemic stroke (IS). The first group consisted of 30 patients with DM 2, the second group enrolled 30 patients without diabetes. At the beginning of the study, we collected complaints, anamnesis, analyzed risk factors for CAN, examined the patients according to the NIH Stroke Scale and the Rankin Scale, carried out cardiovascular tests (CVT) for CAN detection, electrocardiography, 24-hour blood pressure monitoring, and electroneuromyography. The patients underwent passive verticalization for 12 days, which was followed by neurological examination, CVT and ECG. We used both descriptive (calculating the median, 25th and 75th quartiles) and nonparametric statistics (Mann–Whitney U-test, Wilcoxon signed-rank test, Cochran's Q test) for data processing. Results. Initially, patients with DM 2 demonstrated significant changes in all CVTs, and a predominance of the advanced CAN. Confirmed CAN prevailed in the patients of the second group. After verticalization, some positive changes in neurological scales, CVT, and CAN severity were observed in patients of both groups. However, at the end of the trial, the decrease in CAN manifestation in patients with IS associated with DM 2 was less pronounced as compared with patients without DM. Conclusion. Passive verticalization helps to reduce CAN manifestations in patients with IS, including those with associated DM 2.

Гетерогенные патологии, сопутствующие инсульту, обусловливают особенности его течения, развитие осложнений, что требует своевременной коррекции при составлении реабилитационных программ. Недооценка симптомов кардиальной автономной нейропатии (КАН) на фоне сахарного диабета 2-го типа (СД 2) ухудшает прогноз при ишемическом инсульте. Цель работы – изучить проявления кардиальной автономной нейропатии у пациентов с ишемическим инсультом на фоне СД 2 и оценить их динамику при проведении вертикализации. Материалы и методы. В исследовании участвовали 60 пациентов обоего пола 45–75 лет с ишемическим инсультом (ИИ) в острейшем периоде. Первую группу составили 30 пациентов с СД 2, вторую группу – 30 пациентов без данного заболевания. В начале исследования проводились сбор жалоб, анамнеза, анализ факторов риска КАН, оценка по шкалам NIHSS, Рэнкин, кардиоваскулярные тесты (КВТ) на выявление КАН, электрокардиография, суточное мониторирование артериального давления, электронейромиография. На протяжении 12 дней пациентам осуществлялась пассивная вертикализация. Затем повторно проводились неврологический осмотр, КВТ и ЭКГ. Для статистической обработки данных использовалась описательная (подсчет медианы, 25-го и 75-го квартилей) и непараметрическая статистика (критерии Манна–Уитни, Вилкоксона, Кохрена). Результаты. Исходно у пациентов с СД 2 выявлены выраженные изменения всех КВТ, преобладание прогрессирующей формы КАН. Во второй группе преобладала подтвержденная форма КАН. После курса вертикализации отмечена положительная динамика по неврологическим шкалам, КВТ, степени выраженности КАН в обеих группах при сохранении различий между ними. У пациентов с ИИ на фоне СД 2 уменьшение проявлений КАН в конце исследования было менее выраженным по сравнению с пациентами без СД. Выводы. Пассивная вертикализация способствует уменьшению проявлений КАН у пациентов с ИИ, в т.ч. на фоне СД 2. Ключевые слова: кардиальная автономная нейропатия, вертикализация, ишемический инсульт, сахарный диабет.
