Introduction and aim - to determine the relationship of dyslipidemia and endothelial shear rate in the unpaired visceral arteries in patients with atherosclerosis in the abdominal aorta pool. Mathereals and methods. The study included 50 people. All patients were examined by a single protocol. Conduct a full clinical-laboratory and instrumental examination, supplemented by the following laboratory parameters: total cholesterol (TC), triglycerides, HDL, LDL, apolipoprotein A1, apolipoprotein B, Remnant cholesterol calculated using the formula: total cholesterol - (HDL+LDL). All patients underwent Doppler ultrasound unpaired branches of the abdominal aorta ultrasound scanner Voluson E6 (General Electric) was performed, Toshiba Aplio 500. Measurement of the shear rate (shear rate) is determined by the formula: SR=4xVpeak/Vd, Vpeak - peak flow rate visceral branches of the abdominal aorta, Vd - end-diastolic diameter of the visceral branches of the abdominal aorta. Results and discussion. The analysis of the various characteristics of the regional blood flow showed lower values of shear rate in the celiac trunk in patients with atherosclerosis of the visceral branches of the aorta. In the group of patients with abdominal aortic atherosclerosis pool demonstrated significantly lower levels of HDL, higher levels of VLDL, atherogenic factor, apolipoprotein B, triglycerides and Remnant cholesterol. Correlation analysis revealed an inverse association between the level of Remnant cholesterol and shear rate in the celiac trunk (r = -0.284, p = 0.04). Conclusions. The development of atherosclerosis in the celiac trunk and/or the superior mesenteric artery is associated with higher triglycerides, VLDL, Remnant cholesterol, apoliporoteinom B. In patients with atherosclerosis of visceral arteries decrease in endothelial shear rate in the celiac trunk was correlated with increased levels of Remnant cholesterol.

Abstract AIMS To critically evaluate the clinical implications of the use of non-fasting rather than fasting lipid profiles and to provide guidance for the laboratory reporting of abnormal non-fasting or fasting lipid profiles. METHODS AND RESULTS Extensive observational data, in which random non-fasting lipid profiles have been compared with those determined under fasting conditions, indicate that the maximal mean changes at 1–6 h after habitual meals are not clinically significant [+0.3 mmol/L (26 mg/dL) for triglycerides; −0.2 mmol/L (8 mg/dL) for total cholesterol; −0.2 mmol/L (8 mg/dL) for LDL cholesterol; +0.2 mmol/L (8 mg/dL) for calculated remnant cholesterol; −0.2 mmol/L (8 mg/dL) for calculated non-HDL cholesterol]; concentrations of HDL cholesterol, apolipoprotein A1, apolipoprotein B, and lipoprotein(a) are not affected by fasting/non-fasting status. In addition, non-fasting and fasting concentrations vary similarly over time and are comparable in the prediction of cardiovascular disease. To improve patient compliance with lipid testing, we therefore recommend the routine use of non-fasting lipid profiles, whereas fasting sampling may be considered when non-fasting triglycerides are >5 mmol/L (440 mg/dL). For non-fasting samples, laboratory reports should flag abnormal concentrations as triglycerides ≥2 mmol/L (175 mg/dL), total cholesterol ≥5 mmol/L (190 mg/dL), LDL cholesterol ≥3 mmol/L (115 mg/dL), calculated remnant cholesterol ≥0.9 mmol/L (35 mg/dL), calculated non-HDL cholesterol ≥3.9 mmol/L (150 mg/dL), HDL cholesterol ≤1 mmol/L (40 mg/dL), apolipoprotein A1 ≤1.25 g/L (125 mg/dL), apolipoprotein B ≥1.0 g/L (100 mg/dL), and lipoprotein(a) ≥50 mg/dL (80th percentile); for fasting samples, abnormal concentrations correspond to triglycerides ≥1.7 mmol/L (150 mg/dL). Life-threatening concentrations require separate referral for the risk of pancreatitis when triglycerides are >10 mmol/L (880 mg/dL), for homozygous familial hypercholesterolemia when LDL cholesterol is >13 mmol/L (500 mg/dL), for heterozygous familial hypercholesterolemia when LDL cholesterol is >5 mmol/L (190 mg/dL), and for very high cardiovascular risk when lipoprotein(a) >150 mg/dL (99th percentile). CONCLUSIONS We recommend that non-fasting blood samples be routinely used for the assessment of plasma lipid profiles. Laboratory reports should flag abnormal values on the basis of desirable concentration cutpoints. Non-fasting and fasting measurements should be complementary but not mutually exclusive.

Abstract Background Hypocholesterolemia is the most frequently encountered lipid abnormality in sickle cell disease (SCD). We enrolled pediatric patients to determine the relationships between lipid profile and parameters of hemolysis, oxidative stress and chronic inflammation in SCD. Methods The study involved 35 pediatric SCD patients and 19 healthy controls. Patients were crisis-free and had not received transfusions for the last 3 months. Total cholesterol, triglyceride, HDL-C, LDL-C, VLDL-C, apolipoprotein A1, apolipoprotein B, LCAT, LDH, bilirubin, haptoglobin, iron, ferritin, hemin, serum amyloid A (SAA), myeloperoxidase (MPO), uric acid, ALT and GGT levels were evaluated in patients’ blood. Results Patients had hypocholesterolemia depicted by lower levels of total cholesterol, HDL-C, LDL-C, as well as Apolipoprotein A1 and Apolipoprotein B compared to controls. The chronic hemolysis of SCD was evident in patients by higher LDH and bilirubin and almost undetectable haptoglobin levels. Hemin levels (as a measure of oxidized heme) were significantly increased in patients with SCD. Inflammation markers, SAA and MPO, were significantly increased in the patients as well. There were negative correlations between HDL-C and LDH, and Apo A1 and SAA. Hemin was positively correlated to MPO. Conclusion Hemolysis was associated with decreased HDL –C, and Inflammation was linked to decreased apolipoprotein A1 levels in our SCD patients. Therefore, we suggest that the HDL particle is altered during the course of the disease. The altered HDL in SCD may become dysfunctional and result with a slowing down of the reverse cholesterol transport.

Postprandial Lipid

Hypopituitary patients, particularly women, have excess mortality, mostly due to vascular disease. We have studied circulating lipid and lipoprotein concentrations, fasting and over 24 h, in hypopituitary women and men and in matched controls. Firstly, 67 hypopituitary patients (36 women) and 87 normal controls (54 women) were studied after an overnight fast. Secondly, 12 patients (6 women) and 14 matched controls (7 women) were studied over 24 h of normal meals and activity. The patients were all GH deficient and were replaced with cortisol, T4, and sex hormones where appropriate, but not with GH. In the first study, circulating triglycerides, total cholesterol, high density lipoprotein (HDL) cholesterol, and low density lipoprotein (LDL) cholesterol were measured after an overnight fast. In the second study, fasting levels of apolipoprotein B, apolipoprotein A1, and lipoprotein(a) were also measured, and then circulating triglyceride and total cholesterol concentrations were measured over 24 h. Fasting concentrations of triglyceride (mean ± sem, 1.73 ± 0.22 vs. 1.11 ± 0.09 mmol/L; P = 0.0025), total cholesterol (6.45 ± 0.25 vs. 5.59± 0.21 mmol/L; P = 0.002), LDL cholesterol (4.58 ± 0.24 vs. 3.80 ± 0.19 mmol/L; P = 0.007), and apolipoprotein B (135 ± 10 vs. 111 ± 9 mg/dL; P = 0.048) were elevated in hypopituitary compared to control women. The lipid alterations were observed in older and younger women and occurred independently of sex hormone or glucocorticoid replacement. Fasting values were not significantly different in hypopituitary and control men. Patients and controls (women and men) had similar fasting HDL cholesterol, apolipoprotein A1, and lipoprotein(a) concentrations. Although the differences that existed in fasting lipid values were most marked in women, the men were also abnormal in this respect, in that a higher proportion of hypopituitary than control men had total and LDL cholesterol above recommended values (≥6.2 and ≥4.1 mmol/L, respectively). In the postprandial period (0730–2030 h), the areas under the curve (AUC) for circulating triglyceride and total cholesterol were significantly higher in hypopituitary than control women (P = 0.0089 and P = 0.0016, respectively). The AUC for triglyceride and total cholesterol over 24 h were also significantly increased (P= 0.009 and P = 0.0004, respectively). No significant differences were observed for postprandial and 24-h AUC for triglyceride and total cholesterol concentrations in men. We conclude that hypopituitarism with conventional replacement therapy is associated with unfavorable fasting and postprandial lipid and lipoprotein concentrations, particularly in women. The changes may contribute to the observed increased vascular morbidity and mortality.

Introduction. Aneurysms of visceral arteries in the abdominal cavity are very rare. Often aneurysms of branches of the abdominal aorta are an incidental finding as patients seldom present obvious clinical signs or pathological changes in the organ supplied by the artery involved. The incidence of aneurysms of branches connecting the celiac trunk and the upper mesenteric artery amounts to 3.5% of all the cases of aneurysms of abdominal aorta arteries, mostly the gastroduodenal artery. This paper presents a case of minimally invasive treatment of gastroduodenal artery pseudoaneurysm at the BSMU Clinic.Materials and methods. Patient K, a 47-year-old female, was admitted for emergency treatment at the Bashkir State Medical University Clinic in May 2019. The patient’s complaints included feeling weak, black stool for seven days prior, faintness and epigastric pain.Results and discussions. Instrumental examination and angiography data demonstrated that the size of the pseudoaneurysm has increased 2.5 times and reached 65×45 mm; the clinical picture led to the conclusion that the aneurysm was ready to rupture and that there was an immediate need to stop the blood flow to the gastroduodenal artery pseudoaneurysm.Conclusion. The range of currently available image-guided surgical procedures makes it possible to perform adequate embolization of pathological structures such as artery aneurysms.

Blood Total Cholesterol

Background: Literature shows an inverse association of circulating cholesterol level with the risk of Parkinson’s disease (PD); this finding has important ramifications, but its interpretation has been debated. Objective: To longitudinally examine how blood total cholesterol changes during the development of PD. Methods: In the Health, Aging and Body Composition study (n = 3,075, 73.6±2.9 years), blood total cholesterol was measured at clinic visit years 1, 2, 4, 6, 8, 10, and 11. We first examined baseline cholesterol in relation to PD risk, adjusting for potential confounders and competing risk of death. Then, by contrasting the observed with expected cholesterol levels, we examined the trajectory of changes in total cholesterol before and after disease diagnosis. Results: Compared to the lowest tertile of baseline total cholesterol, the cumulative incident ratio of PD and 95%confidence interval was 0.41 (0.20, 0.86) for the second tertile, and 0.69 (0.35, 1.35) for the third tertile. In the analysis that examined change of total cholesterol level before and after PD diagnosis, we found that its level began to decrease in the prodromal stage of PD and became statistically lower than the expected values∼4 years before disease diagnosis (observed-expected difference, –6.68 mg/dL (95%confidence interval: –13.14, –0.22)). The decreasing trend persisted thereafter; by year-6 post-diagnosis, the difference increased to –13.59 mg/dL (95%confidence interval: –22.12, –5.06), although the linear trend did not reach statistical significance (p = 0.10). Conclusion: Circulating total cholesterol began to decrease in the prodromal stage of PD, which may in part explain its reported inverse association with PD.

For the treatment of familial hypercholesterolemia, Liposorber LA-40 was clinically applied. The Liposorber is a commercially developed affinity adsorbent for plasma perfusion which selectivily adsorbs low density lipoproteins and very low density lipoproteins and is specially designed for plasmapheretic treatment of hypercholesterolemia. The Liposorber column, containing activated cellulose beads having an affinity for liporpotein containing apolipoprotein-B, has an excellent adsorption capacity, excellent selectivity, minimum albumin loss. This new apheresis system was applied to 2 clinical cases. After seven months of trial perfusion every 2 weeks, patient condition was good, with a level of total cholesterol under 300 mg/dl. No replacement fluids were given during or after treatment. In this paper, clinical results of these patients were shown and the mechanism of adsorption of this specific adsorbent was discussed.
