Background. Atherogenic lipoproteins, such as total cholesterol, LDL cholesterol, oxidized low density lipoprotein, and triglycerides, are associated with progression of retinopathy.Aim. To evaluate the relationship between lipoprotein(a) and retinopathy in patients with type 2 diabetes mellitus.Materials and Methods. We enrolled 145 diabetic consecutive patients (82 females, 63 males; mean age66.8±12years, mean duration of diabetes9.4±6.8years). Presence and severity of retinopathy were evaluated. Serum lipid profile, including Lp(a) level, was assessed.Results. High Lp(a) levels have been observed in 54 (78.3%) subjects and normal levels in 13 (18.85%) subjects as regards diabetic patients with retinopathy. Lp(a) levels were high in 15 subjects (21.75%) and normal in 63 subjects (91.35%) as regards patients without retinopathy.Conclusions. Lp(a) levels are increased in a significant percentage of patients with retinopathy compared to diabetic patients without retinopathy. The impact of Lp(a) levels on diabetic retinopathy needs to be further investigated.

Introduction: The aim of this study was to compare oxidized low-density lipoprotein (oxLDL) and blood glucose in very low and low levels of vitamin D.Methods: A total of 25 type-2 diabetic patients with very low serum levels of 25-hydroxy vitamin D (severe deficiency – <10 ng/ml); and 25 type-2 diabetic patients with low serum levels of 25-hydroxy vitamin D (deficient – 10 to 30 ng/ml) were recruited in this cross-sectional study. Fasting plasma glucose (FBS), postprandial glucose (PPG), HbA1C, oxLDL, and high-sensitivity C-reactive protein (hs-CRP) were measured. Diagnostic accuracies were determined by receiver-operating characteristic (ROC) curve analysis and measuring the area under the curve (AUC).Results: Patients with severe vitamin D deficiency had higher FBS, PPG, HbA1C, and oxLDL than the vitamin D deficient group (P<0.05). We showed that the AUC of FBS, PPG, HbA1C, and oxLDL were in the range of 0.7-0.9, which indicates moderate accuracies in differentiating severe vitamin D deficiency from deficiency condition.Conclusion: In conclusion, diabetic patients with severe vitamin D deficiency had higher FBS, PPG, and oxLDL levels compared with deficient ones. ROC curve analysis of FBS, PPG, HbA1C, and oxLDL showed these markers are independent predictors of severe vitamin D deficiency and significantly discriminate between very low and low levels of vitamin D deficiency in patients with diabetes. Keywords: Type 2 diabetes mellitus. Vitamin D deficiency. OxLDL. Fasting blood glucose.

Introduction: Carbamylated low-density lipoprotein (cLDL) has profound proatherogenic properties. Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) has been identified as the primary cLDL receptor. The soluble form of LOX-1 (sLOX-1) and 3-nitrotyrosine (NT) have recently been suggested as biomarkers of vascular disease. Although type 2 diabetes mellitus (T2DM) is characterised by an increased atherosclerotic risk, the clinical data on cLDL, NT and sLOX-1 levels in T2DM are limited. Aim: To explore the possible role of cLDL, NT and sLOX-1 as potential biomarkers for disease progression and complications in poorly controlled T2DM patients with and without microalbuminuria. Materials and methods: The serum concentrations of cLDL, NT and sLOX-1 were measured by ELISA in a cross-sectional study of 60 T2DM patients and 35 nondiabetic controls.Results: Both the normoalbuminuric (n = 34) and the microalbuminuric (n = 26) patients had significantly higher serum levels of cLDL and NT than the healthy controls, but sLOX-1 was only elevated in the microalbuminuric subgroup (p < 0.05). Carbamylated LDL correlated positively with NT in the diabetic subjects (rs = 0.266, p = 0.04) while it correlated with urea only in the control group (rs = 0.475, p = 0.004). The serum concentration of sLOX-1 correlated significantly with fasting glucose (rs = 0.441, p < 0.001), HbA1c (rs = 0.328, p = 0.01) and microalbuminuria (rs = 0.272, p = 0.035) in the whole diabetic cohort. Conclusions: The present study highlights the potential of cLDL, NT and sLOX-1 as possible markers of diabetic complications.

Цель - исследование взаимосвязи факторов риска сердечно-сосудистых заболеваний и развития предгипертонии. Методика. Проведен сравнительный и корреляционный анализы показателей модифицируемых и немодифицируемых факторов риска сердечно-сосудистых заболеваний у обследованных лиц в возрасте 30-60 лет с «оптимальным» артериальным давлением, (n = 63, АД <120/80 мм рт.ст.) и лиц с предгипертонией (n = 52, АД = 120-139/80-89 мм рт.ст.). Результаты. Показано, что лица с предгипертонией по сравнению с группой лиц, имеющих «оптимальное» артериальное давление характеризуются статистически значимо повышенным содержанием холестерина и холестерина липопротеидов низкой плотности, интеллектуальным характером трудовой деятельности, а также значимыми сочетаниями факторов риска: повышенный уровень холестерина липопротеидов низкой плотности с интеллектуальным характером трудовой деятельности; повышенное содержание креатинина с уровнем триглициридов; наследственная отягощенность по заболеваниям почек и интеллектуальным характером трудовой деятельности; наследственная отягощенность по сахарному диабету и гипертрофия левого желудочка сердца. У лиц с предгипертонией документированы перестройки структуры взаимосвязи (количество, направленность и сила корреляций) между показателями факторов риска в сравнении с лицами, имеющими «оптимальное» артериальное давление. Заключение. Выявленные особенности взаимосвязей факторов риска сердечно-сосудистых заболеваний при предгипертонии рассматриваются как проявление начальной стадии дизрегуляционной патологии и нарушения регуляции физиологических систем поддержания оптимального уровня артериального давления. The aim of the study was to investigate the relationship between risk factors for cardiovascular disease and development of prehypertension. Methods. Comparative and correlation analyses of modifiable and non-modifiable risk factors for cardiovascular disease were performed in subjects aged 30-60 with «optimal» blood pressure (n = 63, BP <120/80 mm Hg) and prehypertension (n = 52, BP = 120-139 / 80-89 mm Hg). Results. The group with prehypertension compared with the «optimal» blood pressure group had significantly increased serum levels of low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol, sedentary/intellectual type of occupation, and significant combinations of risk factors. The risk factor combinations included an increased level of LDL cholesterol and a sedentary/intellectual occupation; increased serum levels of creatinine and triglycerides; hereditary burden of kidney disease and a sedentary/intellectual occupation; hereditary burden of diabetes mellitus and cardiac left ventricular hypotrophy. In subjects with prehypertension compared to subjects with «optimal» blood pressure, changes in correlations (correlation number, direction, and strength) between parameters of risk factors were documented. Conclusion. The features of interrelationships between risk factors for cardiovascular disease observed in prehypertension are considered a manifestation of early dysregulation pathology and disordered regulation of physiological systems, which maintain optimal blood pressure.
