Abstract
Present article is devoted to the study of the correlation between vitamin B12 serum level, hyperhomocysteinaemia and dyslipidemia. During research there were discovered that the lowest vitamin B12 serum level and the highest homocysteine serum level have been registrated in associated pathology (ischemic heart disease and acid peptic disease according to long-term proton pump inhibitor use) patients. It was shown evident correlation between that changes and dyslipidemia. Тhe complex therapy that includes parenteral B12 supplementation leads to more effective correction of hyperhomocysteinaemia and dyslipidemia in patients with comorbidity of ischemic heart disease and acid peptic disease with long-term use of proton pump inhibitors.

Abstract
This study compared the effect of simvastatin on lymphocyte secretory function between patients with impaired glucose tolerance (IGT) (n=30) and mixed dyslipidemia (n=29). Lipid profile, glucose metabolism markers (fasting and 2-h post-glucose challenge glucose levels, HOMA-IR and glycated hemoglobin), plasma CRP levels and the release of interleukin-2 and interferon-γ by phytohemagglutinin-stimulated T lymphocytes were determined before and after 30 and 90 days of simvastatin administration (20 mg daily). Phytohemagglutinin-stimulated T cells from both IGT and mixed dyslipidemic subjects released significantly higher amounts of both cytokines than lymphocytes of 30 dyslipidemia-free individuals with normal glucose tolerance. Despite improving the lipid profile, simvastatin produced no effects on glucose metabolism markers in either treatment groups. The drug normalized the lymphocyte cytokine release and plasma hsCRP in mixed dyslipidemic patients but not in IGT patients. Our study indicates that the presence of mixed dyslipidemia and IGT is associated with the enhanced secretory function of human lymphocytes. Simvastatin is an effective lymphocyte-suppressing agent in mixed dyslipidemic patients but not in IGT patients.

Abstract
Clinical observations revealed an increased prevalence of iron deficiency anemia without chronic bleeding in patients treated with serial low-density lipoprotein (LDL) apheresis. Since several different proteins are adsorbed by LDL apheresis beside pro-atherogenic lipoproteins, we examined the modification of the full blood count, plasma iron, vitamin B12, folic acid, and hemolysis by LDL apheresis. Nineteen patients (55 (50-59) years, 4 female, 15 male) undergoing chronic LDL apheresis due to mixed dyslipidemia (N = 17), homozygous familiar hypercholesterolemia (N = 1) or isolated elevated lipoprotein(a) (N = 1) were included in this study. They were treated with direct adsorption of lipoproteins (DALI; N = 6), heparin-induced LDL-precipitation (HELP; N = 7) or double filtration plasmapheresis (DFPP; N = 6). The patients' full blood count, iron metabolism (plasma iron, ferritin, transferrin, transferrin saturation), vitamins involved in erythropoiesis (vitamin B12 and folic acid), and markers of hemolysis (haptoglobin and free hemoglobin) were analyzed directly before and after LDL apheresis. A single LDL apheresis session significantly decreased the levels (reduction in the median [25(th)-75(th) percentiles] of: ferritin 9.8 [1.3-18] %; P = 0.004), transferrin (12.1 [10.0-15.96] %; P = 0.0005), and vitamin B12 (17.8 [16.2-20.8] %; P = 0.0005). Thereby, transferrin and vitamin B12 were decreased in all (N = 19) and ferritin in 74% (N = 14) of the patients. Twelve out of 19 patients (63.2%) had mild anemia despite iron administration in 14 out of 19 patients (73.7%). LDL apheresis had no significant influence on full blood count, plasma iron, transferrin saturation, folic acid, or hemolysis. Similar changes were observed in all LDL apheresis methods used. LDL apheresis significantly decreases ferritin, transferrin, and vitamin B12, suggesting an influence of serial LDL apheresis on erythropoiesis.

Abstract
A new cookie test was developed for the simultaneous evaluation of multiple risk factors such as glucose intolerance, hyperinsulinemia, insulin resistance and postprandial dyslipidemia. The cookie consisting of 75 g carbohydrate and 25 g fat is ingested and the blood samples are obtained at 0, 1 and 2 hours later. When the two carbohydrate sources, liquid glucose and test cookie, were compared as a glucose load within 3 months, the 2 hr plasma glucose levels were not statistically different, proposing the use of the same criteria at 2 hour glucose level for the diagnosis of diabetes and impaired glucose tolerance (IGT) in subjects without exocrine pancreatic dysfunction. In addition, hyperinsulinemia, insulin resistance (AUC insulin, and/or AUC insulin X AUC glucose), and postprandial hyperlipidemia (DeltaTG, Triglyceride; DeltaRLP, remnant like particles) have been simultaneously uncovered. Reactive hypoglycemia with adverse epigastric discomfort was observed in 26.3% of the control subjects with liquid glucose, while it was observed in only 1 case (5.3%) without any symptom with cookie tests. In fact, one reactive hypoglycemia out of 5 with liquid glucose turned out to be IGT with cookie test. In 64 subjects with lifestyle-related diseases, cookie test revealed hyperinsulinemia and insulin resistance in 56% respectively, postprandial hyperlipidemia in 39%, diabetes and IGT in 22-23% of each of the subjects and all showed at least one abnormal value. In contrast, in university students with exercise habit, all showed normal results with cookie test. In addition, improved insulin sensitivity over non-exercise group was obverved. In summary, the cookie test provided more informations compared with OGTT using liquid glucose and with fewer side effects. Simultaneous evaluation of glucose intolerance, hyperinsulinemia, insulin resistance, and postprandial hyperlipidemia was also possible.
