Objective. To assess prevalence of metabolically healthy individuals among patients with abdominal obesity (AO) and to determine phenotype and potential genetic traits associated with a benign metabolic status. Methods. 503 AO patients without cardiovascular diseases were examined. Waist circumference (WC), BMI, blood pressure, plasma glucose and serum insulin levels, HOMA-IR, lipid profile, and adiponectin (AN) and leptin (LEP) concentrations in serum were measured. Polymorphisms A19G and Q223R of the LEP and LEP receptor gene, and G276T and T45G of the AN gene were investigated. Results. 91.3% of patients were metabolically unhealthy obese (MUO), and 8.7% metabolically healthy obese (MHO). MHO patients were younger, and had lesser BMI and WC, while duration of obesity, frequency, and duration of physical training were greater than MUO patients (p < 0.05). In MHO and MUO patients distribution of the G19G, G19A, and A19A genotypes of the LEP gene and G276G, G276T, and T276T genotypes of AN gene did not differ. The Т45Т genotype was associated with increase of metabolic disorders' risk for patients with АО (OR = 2.331; 95%  CI = 1.121 ÷ 5.132). Conclusions. Prevalence of MHO individuals among patients with AO is low. Benign metabolic status was associated with younger age, lower waist circumference, and higher physical activity, shorter duration of obesity, and G45G adiponectin genotype carriage.

The population of Russia consists of more than 150 local ethnicities. The ethnic diversity and geographic origins, which extend from eastern Europe to Asia, make the population uniquely positioned to investigate the shared properties of inherited disease risks between European and Asian ethnicities. We present the analysis of genetic and phenotypic data from a cohort of 4,145 individuals collected in three metro areas in western Russia. We show the presence of multiple admixed ancestry clusters spanning from primarily European to Asian and high identity-by-descent sharing with the Finnish population. As a result, there was notable enrichment of Finnish-specific variants in Russia. We illustrate the utility of Russian-descent cohorts for discovery of novel population-specific genetic associations, as well as replication of previously identified associations that were thought to be population-specific in other cohorts. Finally, we provide access to a database of GWAS results for 465 unique phenotypes and allele frequencies.

Актуальность. Адипонектин (АН) - протективный адипоцитокин, продуцируемый жировой тканью и циркулирующий в крови в виде различных изомеров. При абдоминальном ожирении (АО) сниженная концентрация АН ассоциируется с развитием метаболи- ческого синдрома (МС), его отдельных компонентов и различных сердечно-сосудистых заболеваний. АН кодируется геном ADIPOQ . Показано, что генетические варианты ADIPOQ ассоциированы с изменением концентрации АН сыворотки крови.Цель исследования. Выявить ассоциации полиморфных вариантов T(+45)G rs2441766 и С(-11377)G rs 266729 гена ADIPOQ с кон- центрацией АН сыворотки крови, АО и МС у женщин.Результаты. Обследованы 302 женщины с АО в возрасте от 30 до 55 лет. Группу сравнения составила 161 практически здоровая женщина без АО. У 185 обследованных с АО был диагностирован МС в соответствии с критериями Международной федерации диа- бета (IDF, 2005). Частоты генотипов и аллелей вариантов T(+45)G и С(-11377)G гена ADIPOQ у женщин с АО и без АО не различались (р>0,05). Среди женщин с АО и МС реже встречались носители аллеля G варианта T(+45)G гена ADIPOQ , чем среди женщин с АО без МС (р<0,05). Частоты генотипов и аллелей варианта С(-11377)G гена ADIPOQ у женщин с АО и МС и у пациенток с АО без МС не разли- чались (р>0,05). У женщин с АО - носителей аллеля G варианта T(+45)G гена ADIPOQ концентрация высокомолекулярного АН (ВМАН) была выше, чем у носителей генотипа TТ этого гена. При анализе частот гаплотипов вариантов T(+45)G и С(-11377)G гена ADIPOQ в обследованных группах достоверных различий не выявлено (р>0,05). Концентрации общего АН в сыворотке крови у женщин с АО и МС - носителей различных генотипов и гаплотипов вариантов T(+45)G и С(-11377)G гена ADIPOQ не различались (р>0,05). Концен- трация ВМАН у женщин с АО - носителей гаплотипа TGC(X) (Х - аллель С или G варианта С(-11377)G ) была выше, чем у женщин с АО - носителей других гаплотипов гена ADIPOQ (р<0,05).Выводы. Носительство аллеля G варианта T(+45)G гена ADIPOQ является протективным в отношении МС у женщин с АО. У женщин с АО - носителей аллеля G концентрация ВМАН выше, чем у женщин с АО - носителей TT генотипа варианта T(+45)G гена ADIPOQ . Background. Adiponectin (AN) - a protective adipocytokine, produced by fat tissue and circulating in the form of various isomers in the blood. With obesity, a decreased level of AN is associated with the development of metabolic syndrome (MS) and various cardiovascular diseases. Regulation of its level can be caused by genetic factors, including single nucleotide polymorphism T(+45)G and C(-11377)G of the ADIPOQ gene. Allelic variants of the ADIPOQ gene was associated with AN concentrarion in blood.Objective. To identify the association of genetic variants of ADIPOQ with adiponectin level, AO and MS in women.Results. A total of 302 women with abdominal obesity (AO) aged 30-55 years were examined. The comparison group consisted of 161 practically healthy women without AO. 185 patients with AO had MS according to the criteria of the International Diabetes Federation (IDF, 2005). The frequencies of genotypes and alleles of variants T (+45) G and C (-11377) G of the ADIPOQ gene among women with and without AO did not differ (p> 0,05). Among women with AO and MS, carriers of G allele variant T (+45) G of the ADIPOQ gene were less common than among women with AO without MS (р<0,05). The frequencies of genotypes and alleles of variant C (-11377) G of the ADIPOQ gene did not differ in women with AO and MS and in patients with AO without MS (p> 0.05). In women with AO - carriers of the G allele variant T (+45) G of the ADIPOQ gene, the concentration of high molecular weight AN (HMWA) was higher than that of the TT carriers of the genotype of this gene The haplotypes of the T (+45) G and C (-11377) G variants of the ADIPOQ gene did not differ in the studied groups (p> 0,05). The con- centration of total AN in the serum of women with AO and MS - carriers of different genotypes and haplotypes of variants T (+45) G and C (-11377) G of the ADIPOQ gene did not differ (p> 0,05). The concentration of HMWA in women with AO - carriers of the TGC(X) haplotype (X - allele C or G variant C (-11377) G) was higher than in women with AO - carriers of other haplotypes of the ADIPOQ gene (p <0,05). Coclusions. G allele of the T(+45)G variant the ADIPOQ gene is protective against MS in women with AO. In women with AO - carriers of the G allele, the concentration of HMWA is higher than in women with AO - carriers of the TT genotype of variant T(+45)G of the ADIPOQ gene.

In people with vitamin D deficiency, anxiety and depression were noted in 32.5% and 11.0%, respectively. There were negative correlations between serum 25(OH)D level and anxiety (r= -0,11, p=0.03). Symptoms of depression were not correlated with vitamin D status (r= -0.08, p=0.09) but were correlated with the age (r=0.12, p=0.02). After excluding other risk factors for psychogenic disturbances (obesity, hypertension and impaired glucose metabolism) we concluded that serum 25(OH)D could be an independent risk factor for anxiety (R2=0.02, p=0.01) in the population studied.
