    Introduction. Cystic fibrosis (CF) is a  hereditary disease with genetic heterogeneity and clinical polymorphism. Expanding the range of knowledge about the characteristics of the course of the disease in different regions is important to achieve the goal of improving the quality and life expectancy.Purpose. Comparative analysis of the features of the course of CF in the subjects of the Southern Federal District, Stavropol Territory.Methods. Data from the National Register of Patients of the RF MV 2016 were used. Results: there are clinical and genetic features between the regions of the Southern Federal District and the Stavropol Territory of the North Caucasus Federal District and in general with the Russian Federation. Analysis of the data showed differences in indicators: the proportion of patients aged ≥ 18 is the lowest in the Republic of Crimea (14.9%), in the Rostov region the lowest average age of patients (9.0 ± 6.3), and the lowest age of diagnosis 2.2 ± 3.1 years. Late terms of diagnosis were revealed in the Stavropol Territory (4.0 ± 8.0 years), but here there is one of the highest average age of CF patients (14.1 ± 11.5), the proportion of adult patients (23.3%) and the lowest allelic frequency of F508del, which is determined by the high number of patients with a “soft” genotype. There is a high proportion of patients with an undetermined genotype. A low proportion of two identified genetic variants of the CFTR gene is registered in patients of the Republic of Crimea. A low frequency of Burkholderia cepacia complex and Achromobacter spp was revealed, and a high infection with non-tuberculous mycobacteria was revealed in the Rostov region. FEV1 in children and adults was lower in Rostov Region and Stavropol Territory. In all regions, there is a discrepancy between the seeding of flora and azithromycin therapy and the severity of the genotype with the use of pancreatic enzymes.Conclusions. Analysis of the data of the registry, which allows substantiating the need to study the regional characteristics of the course of CF in order to differentiate the planning of measures to improve the quality of medical care for patients with CF

    Atorvastatin induces associated reductions in platelet P-selectin, oxidized low-density lipoprotein, and interleukin-6 in patients with coronary artery diseases.

    The development and progression of atherosclerosis comprises various processes, such as endothelial dysfunction, chronic inflammation, thrombus formation, and lipid profile modification. Statins are 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors that have pleiotropic effects in addition to cholesterol-lowering properties. However, the mechanisms of these effects are not completely understood. Here, we investigated whether atorvastatin affects the levels of malondialdehyde-modified low-density lipoprotein (MDALDL), an oxidized LDL, the proinflammatory cytokine interleukin-6 (IL-6), or platelet P-selectin, a marker of platelet activation, relative to that of LDL cholesterol (LDL-C). Forty-eight patients with coronary artery disease and hyperlipidemia were separated into two groups that were administered with (atorvastatin group) or without (control group) atorvastatin. The baseline MDA-LDL level in all participants significantly correlated with LDL-C (r = 0.71, P < 0.01) and apolipoprotein B levels (r = 0.66, P < 0.01). Atorvastatin (10 mg/day) significantly reduced the LDL-C level within 4 weeks and persisted for a further 8 weeks of administration. Atorvastatin also reduced the MDA-LDL level within 4 weeks and further reduced it over the next 8 weeks. Platelet P-selectin expression did not change until 4 weeks of administration and then significantly decreased at 12 weeks, whereas the IL-6 level was gradually, but not significantly, reduced at 12 weeks. In contrast, none of these parameters significantly changed in the control group within these time frames. The reduction (%) in IL-6 between 4 and 12 weeks after atorvastatin administration significantly correlated with that of MDALDL and of platelet P-selectin (r = 0.65, P < 0.05 and r = 0.70, P < 0.05, respectively). These results suggested that the positive effects of atorvastatin on the LDL-C oxidation, platelet activation and inflammation that are involved in atherosclerotic processes are exerted in concert after lowering LDL-C
