Interrelation of cardiovascular risk factors with high albuminury among patients with arterial hypertension living in Mountain Shoriya.

AIM: To evaluate the association of a complex of cardiovascular risk factors and genetic markers with the development of high albuminuria among patients with arterial hypertension in the population of Mountain Shoriya, taking into account ethnicity. MATERIALS AND METHODS: A clinical epidemiological study of a compactly residing population in remote areas of Mountain Shoria was carried out. 1409 people were examined [901 people - representatives of the indigenous nationality (Shorians), 508 people - representatives of non-indigenous nationality (90% of them are Caucasians)]. Hypertension was diagnosed according to the National Guidelines of the Russian Society of Cardiology/the Russian Medical Society on Arterial Hypertension (2010). All patients underwent clinical, laboratory and instrumental investigation. To study the state of the kidneys, the concentration (the presence of elevated levels) of albumin (albuminuria) in the morning portion of urine by an immunoturbidimetric method was analyzed. Polymorphisms of genes ACE (I/D, rs4340), АGT (c.803T>C, rs699), AGTR1 (А1166С, rs5186), ADRB1 (с.145A>G, Ser49Gly, rs1801252), ADRA2B (I/D, rs28365031), MTHFR (c.677С>Т, Ala222Val, rs1801133) and NOS3 (VNTR, 4b/4a) were tested using PCR. RESULTS: In the group of shors with arterial hypertension, high albuminuria was associated with polymorphisms of the ACE genes (OR=2.05), ADRA2B (OR=6.00), elevated triglyceride level (OR=2.86), decreased index of cholesterol of high density lipoproteins (OR=5.57) and increased index of low density lipoproteins (OR=2.49); in the new population - with polymorphisms of the AGTR1 genes (OR=8.66), ADRA2B (OR=6.53), MTHFR (OR=7.16), obesity (OR=2.72), and abdominal obesity (OR=3.14). CONCLUSION: The primary predictors determining the development of high albuminuria among patients with arterial hypertension in both ethnic groups were genetic ones. In addition to them, non-genetic risk factors also contributed to the development of this organ damage to the kidneys: age and lipid metabolism disorders in representatives of indigenous nationality; age and abdominal obesity in the examined patients non-indigenous nationality.

[Genetic determinants of hypertension in two national cohorts of Mountain Shoria]. / Geneticheskie determinanty arterial'noi gipertonii v dvukh natsional'nykh kogortakh Gornoi Shorii.

AIM: To estimate the prevalence of the genotypes of the candidate genes ACE (I/D, rs4646994), ADRB1 (Ser49Gly, A/G, rs1801252) ADRA2B (I/D), MTHFR (C677T, Ala222Val, rs1801133), and eNOS (4b/4a) and their association with hypertension in two ethnic groups of Mountain Shoria. SUBJECTS AND METHODS: A clinical and epidemiological study was conducted in a population compactly living in the hard-to-reach areas of Mountain Shoria (the settlements of Orton, Ust-Kabyrza, and Sheregesh of the Kemerovo Region). A continuous method was used to survey 1178 residents from the above settlements; the sample consisted of adults (aged 18 years and older), 565 people were genotyped. RESULTS: The prevalence of hypertension among the population of Mountain Shoria was 42.3%. The incidence of this disease among the Shorians was lower (39.9%) than that among the representatives of non-indigenous people (46.1%). The ethnically justified peculiarities of the association of ADRA2B and ACE I/D polymorphisms with hypertension were established. There were fewer patients with hypertension among ACE ID and ADRA2B DD genotype carriers in the cohort of the Shorians than in that of the non-indigenous population: 40.6% versus 58.6% and 38.3% versus 64%, respectively. Conversely, there were more hypertensive patients among the carriers of the homozygous ACE DD genotype in the native ethnic group (60%) than in the non-indigenous one (37.1%). CONCLUSION: Adverse prognostic ACE DD, ADRB1 AA, MTHFR TT, and eNOS 4a/4a genotypes were more frequently observed in the non-indigenous ethnic groups; the ADRA2B DD genotype was more common in the native population. Hypertension was associated with the ACE DD, МTHFR CT, and ADRB1 AA genotypes in the native ethnic group and with the ACE ID genotype in the non-indigenous population.

[Use of calcium channel blockers for prophylaxis of multiple organ failure in acute destructive pancreatitis]. / Blokatory kal'tsievykh kanalov v profilaktike poliorgannoi nedostatochnosti pri destruktivnom pankreatite.

The purpose of this study was to investigate effectiveness of the usage of calcium channels blockers and plasmaleukopheresis in prophylaxis of the syndrome of polyorganic insufficiency (SPI) in patients with acute destructive pancreatitis. 30 patients operated on for pancreonecrosis were divided into 2 groups: study group (13 patients) and control one (17 patients) matched for sex, age, extent and character of changes in the pancreas. Taking into account a substantial role of hyperactive neutrophils in pathogenesis of SPI, Verapamil (dose of 0.5 mg/kg/day) and discrete plasmaleukopheresis were included in the complex of treatment for patients of the study group. Effectiveness of the treatment was assessed according to the quantity of complications, lethality values of leukocytosis and leukocyte index of intoxication (LII) as well as by the scale of the severity of sepsis (SSS). Complicated postoperative course was seen in 41.18% of cases in the control group and 23.07%--in the study one. Lethality in the control group made up 11.8% (2 patients); there were no lethal outcomes in the study group. Anearlier decrease in leukocytes count, LII and SSS in the study group was significant. The conclusion is made on effectiveness of the use of calcium channels blockers and discrete plasmaleukopheresis for prophylaxis of SPI in acute destructive pancreatitis.
