Cím:Evaluation of genetic risk related to high fasting glucose level in the Hungarian Roma population / Sz. Fiatal, V. Tomori, P. Pikó, Á. Moravcsik-Kornyicki, B. Soltész, A. Nagy, J. Sándor, R. Ádány

Megjegyzések:Background Studies showed that health status of Roma population, which represents the largest minority in Central and Eastern Europe, is significantly worse than that of the general population. It is recently pointed out that the prevalence of raised fasting plasma glucose or known type 2 diabetes mellitus (FPG/T2D) were significantly higher in all age groups in the Hungarian Roma (HR) population than in the Hungarian general (HG) population. Our aim was to identify whether a genetic susceptibility contributes to higher FPG/T2D in the HR population. Methods Eighteen single nucleotide polymorphisms were genotyped (Sequenom, MassARRAY platform) in 753 samples from the population of Roma and 1783 samples from the HG population. A genetic risk score (GRS), both unweighted and weighted were constructed for each individual and were compared using two sided t test. Considering the confounding effects of age, gender and BMI on differences in GRS between study populations, analysis of variance models were constructed. Results Although Roma people do not carry more risk alleles than Hungarians counterparts (20.5 2.8 vs. 20.3 2.9, P = 0.19), the average weighted GRS was significantly higher among them comparing to Hungarians (0.51 0.08 vs. 0.49 0.08, p = 4.8X10-4, respectively). This increase causes the distribution of genetic risk to be right-shifted in HR population compared to HG population. Adjustment for confounding factors did not change the inference of mean difference in weighted GRS (P = 5X10-3). Modelling of cumulative GRS suggested that the per-allele effect estimates are slightly also higher in HR than in HG population (OR= 1.1 vs. OR = 1.08, respectively). Conclusions GRS modelling showed that Roma individuals have greater burden of risk alleles compared to HG population. It suggests that there are ethnic specific differences in genetic architecture underlying raised FPG/T2D, which fosters the stratification of the Hungarian population according to T2D disease risk.

Cím:Increased genetic susceptibility of the Hungarian Roma population to venous thrombosis / S. Fiatal, P. Pikó, Z. Kósa, J. Sándor, R. Ádány
Dátum:2017
ISSN:1101-1262
Megjegyzések:Background Studies on Roma populations show the high prevalence of cardiovascular risk factors among them independently from the countries where they live. Sporadic findings suggest that in addition to the environmental/modifiable risk factors genetic susceptibility may also exist behind the high cardiovascular disease morbidity and mortality burden of Roma. Our aim was to define the genetic susceptibility of Hungarian Roma to venous thrombosis by investigating the prevalence of alleles contributing to thrombophilia to a highest extent and compare it to that of the general population. Methods Based on systematic literature review SNPs (N = 48) associated with venous-thrombosis in 32 genes (e.g. F2, F5, F9, F11, F15, FGA, FGB, FGG, CYP4V2, KLKB1, vWF) were selected and analysed in the Hungarian Roma (N = 962) and general (N = 1492) populations. Differences in allele frequencies, as well as genetic risk scores both unweighted (GRS) and weighted (wGRS) were defined for the study groups and compared to estimate the joint effect of SNPs. Results Differences in allele frequencies between the study populations were significant in case of 29 polymorphisms after multiple test correction, and almost all susceptible alleles were more prevalent in the Roma population. Both GRS and wGRS were found significantly higher in Roma than in the general population (GRS: 39.84 5.35 vs. 38.71 5.59, p<0.001; wGRS: 7 1.8 vs. 6.73 1.9, p < 0.01). Only 1.35% of subjects in the Roma population were in the bottom fifth of the wGRS (wGRS 2.5) compared with 2.28% of those in the general population, while 3.62% of the general subjects were in the top fifth of the wGRS (wGRS 9.9) compared with 5.09% of those in the Roma population (p<0.001). Conclusions The Roma population has increased genetic susceptibility to venous thrombosis as it is indicated by higher GRS values in comparison with that for the Hungarian general population.

Cím:Fasting plasma glucose related genetic variants show ethnic variation in Hungarian populations / Sz. Fiatal, P. Pikó, Zs. Kósa, J. Sándor, R. Ádány
Dátum:2017
ISSN:1101-1262
Megjegyzések:Background Elevated fasting glucose (FG) level is a risk factor for diabetes. Meta-analyses of European populations' data identified many loci associated with glucose metabolism, but knowledge on other ethnicities is limited. Consequently, the generalizability of results to non-Europeans remains to be clarified. We addressed the question whether the individual effect of established FG related genetic loci are applicable to the Roma considered to have a South Asian origin. Methods Genotyping of 21 SNPs in 19 genes (among them C2CD4B, CDC123, CDKAL1, CDKN2A/B, FADS1, G6PC2, GCKR, GLIS3, SLC2A2, TCF7L2) was performed in Hungarian populations (General: N = 1411; Roma: N = 576). Single SNP associations (direction and magnitude of the effect on FG level) were estimated by regression models using covariates (age, sex). Data obtained on study populations were compared to formerly published European data and to each other. Individuals on antidiabetic treatment were excluded. Results The beta coefficients for SNPs on the sample of general population were found to be almost (except rs5219, rs174550) identical both in direction and magnitude, indicating that the effect is mostly concordant with the results obtained in large scale studies on Europeans. However, among Roma in case of 5 SNPs (rs10946398, rs340874, rs7034200, rs1111875 and rs174550) the effect direction differed in comparison with European data. The rs174550 variant showed difference in effect direction in both populations compared to data on Europeans. Between study populations in case of 5 SNPs (rs10946398, rs340874, rs7034200, rs1111875, rs5219) the association differed in direction, in addition one out of these variants (rs1111875) differed also in magnitude, pointing out the notable ethnic variation among Hungarians. Conclusions Differences observed in effect direction in case of 5 SNPs indicate that data obtained on European populations can be utilised in genetic risk estimation models for Roma with cautions.

Cím:Using SNP-based risk estimates in identification of susceptibility to cardiovascular diseases / S. Fiatal, P. Pikó, R. Ádány
Dátum:2018
ISSN:1101-1262
Megjegyzések:Background: Common cardiovascular disorders (CVDs) result from a combination of genetic and environmental factors. Advances in genomics have fostered huge expectations about use of susceptibility variants for prevention, diagnosis, and treatment. We summarized the developments in the field from a public health perspective focusing on the applicability of data on single-nucleotide polymorphisms (SNPs). Methods: Systematic review was performed according to the PRISMA statement using PubMed, Embase, CINAHL, and Web of Science databases. Final records were structured based on main public health domains (prevention, early detection, and treatment) using a four-phase framework suggested for translational research: T1. From gene discovery to candidate health applications; T2. From health application to evidence based practice guidelines; T3. From evidence-based practice guidelines to health practice; T4. From practice to population health impacts. Results: Majority of research belongs to the T1 phase, there are only a few population-based impacts estimated. Studies suggest that a single SNP is a poor estimator of risk, but an individual's genetic profile combined with non-genetic factors better predict CVD risk among certain patient subgroups. More research is needed to validate whether these genomic profiles can prospectively identify individuals at risk to develop CVDs. Research gaps were identified: little information is available on studies suggesting ♭♭Health application to evidence-based practice guidelines''; no study is available on ♭♭Guidelines to health practice.'' It was not possible to identify studies that incorporate environmental or lifestyle factors in the risk estimation. Conclusions: Identifying populations have larger risk of developing common CVDs may result in personalized prevention programs by reducing people's risk of onset or disease progression. However, limited evidence is available on the application of genomic results in health or public health practice.

Cím:Disparities in smoking habits in Hungarian Roma and general populations / S. Fiatal, P. Pikó, Z. Kósa, J. Sándor, R. Ádány
Dátum:2019
ISSN:1101-1262
Megjegyzések:Background: Smoking status, dependence and cessation efforts of the disadvantaged Hungarian Roma living in segregated settlements were compared to those of the general population. Methods: Data were collected through survey. Each study group consists of 500 randomly drawn subjects, and are representative of the adult (18-64) general and Roma population, living in two counties of North-East Hungary. Questions on smoking from the European Health Interview Survey were used with some modifications. Prevalence data were analysed according to age strata (18-29, 30-44 and 45-64 years) by chi2 test, and were compared to data from 2003 and 2014. Results: In Roma the proportion of never smokers is much less compared to the general ones (men:27.27% vs.75%, women:38.6% vs.70.75%, p < 0.05). Less Roma reported never smoking in all age compared to 2014, increasing trend can be found in the general population since 2003. Smoking prevalence is higher in Roma in all ages (72.73% vs.20 83%; 68.42% vs.28.42%; 59.02 vs. 32.26%, p < 0.05, respectively). Interestingly, the prevalence of Roma men smokers is decreasing by age, in the general population the trend is the opposite. Heavy smoker status is the highest in 30-44 age group of both populations. Increasing trend of heavy smoking can be detected in the Roma, but the opposite holds for general population compared to 2014. Half of the Roma smoke within 5 minutes after wakeup (50% vs. 36.92%, p < 0.05), smoke hand-rolled cigarettes (68.91%vs 30.77%, p < 0.05), higher proportion of them tried to quit (34.78% vs. 23.38%, p < 0.05) but smaller proportion of them obtained advise on how to quit (48.53% vs.59.09%, p < 0.05). Initiation starts earlier age among them (men: 15.1 vs.16.6, women: 16.2 vs.18.2, p < 0.05). Conclusions: Regular smoking (especially heavy) is much higher in the Roma and decreasing by age compared to the general in all age-groups. The 30-44 age group of Roma mean are exclusively heavy smokers but half of the Roma show effort to quit.

Cím:Roma socioeconomic status has higher impact on smoking behaviour than genetic susceptibility / M. A. Merzah, P. Pikó, R. Ádány, S. Fiatal
Dátum:2020
ISSN:1101-1262
Megjegyzések:Background: Prevalence of smoking in Hungarian Roma (HR) population is two to five times higher than in Hungarian general (HG) population. Our study aims to examine genetic susceptibility and other possible determinants associated to smoking behaviours in these populations. Methods: A questionnaire based cross-sectional study was designed in HG (N = 412) and HR (N = 402) populations. Ten Single Nucleotide Polymorphisms (SNPs) were genotyped known to be robustly linked to smoking behaviours. Risk allele frequencies were compared. Additive genetic risk scores (unweighted GRS and weighted GRS) were constructed to compare genetic load from SNPs in genes NRXN1, CHRNA5/. 4, AGPHD1, MAOA, TRPC7, KCNJ6, GABRA4, and CYP2A6. Smoking behaviour were associated with GRSs and confoun ders (age, gender, BMI, socioeconomic status-SES) in several regression models. SES was calculated based on Modified Kuppuswamy scale 2019. Results: Risk allele frequencies of four SNPs were found to be different between populations (p < 0.01). Median of GRS was equivalent among in populations; whilst wGRS median was slightly higher among Roma (5.2 compared to Hungarian 4.9; P = 0.02). In Roma both genders were more likely to be heavy smoker (OR = 2.05, 95%CI: 1.47-2.86; OR = 1.89, 95%CI: 1.58-2.25, for males and females, respectively) compared to counterparts from general population. GRS were higher among heavy smokers of both populations compared to other smoking behaviours (ORRoma= 1.06, 95%CI:0.98-1.15; ORHungarian=1.05, 95%CI=0.91-1.2). Strong reversible rela tionship was found between SES and smoking behaviours among study populations (p < 0.0001). Heavy, moderate, and former smokers were having lower SES compared to never smokers of both populations (SES =-0.037, P = 0.04 for Hungarian; =-0.039, P = 0.02 for Roma). Conclusions: Socioeconomic status was shown as a priority indicator based on multifactorial regression analysis. The highest efforts should be focused on improving the SES of Roma population.

Cím:Higher VTE in a Roma population attributed to raised genetic risk and gene-environmental interaction / Natae S., Sándor J., Ádány R., Fiatal S.
Dátum:2022
ISSN:1101-1262
Megjegyzések:Background: Interactions between genetic and environmental risk factors (GxE) contribute to an increased risk of venous thromboem bolism (VTE). Understanding how these factors interact provides insight for the early identification of at-risk groups within a population and creates an opportunity to apply appropriate preventive and curative measures. Objective: To estimate and compare GxE for VTE risk in the general Hungarian and Roma populations. Methods: The study was based on data extracted from a database consisting the results obtained previously in a three pillars complex health survey. DNA was genotyped for rs121909567 (SERPINC1), rs1799963 (F2), rs2036914 (F11), rs2066865 (FGG), rs6025 (F5), and rs8176719 (ABO) polymorphisms. Multivariable linear regression analysis was applied to test the impact of GxE on VTE risk. Results: Interestingly, the rs121909567 (SERPINC1) SNP was not present in the general population, however the risk allele frequency was 1.4% among Roma, which might suggest a founder effect in this minority. The risk of VTE was higher among depressive Roma subjects who carried the risk variant of rs2036914 (b = 0.819, p = 0.02); however, not for the general subjects. The joint presence of high level of LDL-C and rs2066865 increased the VTE risk only among Roma (b = 0.389, p = 0.002). A multiplicative interaction between rs8176719 and cancer was identified and higher for the Roma population (b = 0.370, p < 0.001). The VTE risk increased in the Roma population (b = 0.280, p = 0.001) but was higher in the general population (b = 0.423, p = 0.001) as a result of the multiplicative interaction between CAD and rs2036914 (F11). Conclusions: rs121909567 (SERPINC1) was confirmed as a founder mutation in the Roma population. As a result of higher genetic load and GxE interactions, the minority Roma population is at higher risk of VTE than the general Hungarian population.

Cím:Increased risk of Roma for 10-year development of CVDs based on Framingham Risk Score calculation / P. Piko, Sz. Fiatal, Z. Kosa, J. Sandor, R. Adany
Dátum:2019
ISSN:1101-1262
Megjegyzések:Background: Increased mortality and short life expectancy of Roma are well known epidemiological findings which can be partially explained by the high prevalence of cardiovascular risk factors among them. This study assesses the prevalence of the cardiovascular disease (CVD) risk factors (age, sex, systolic blood pressure, smoking and diabetes status, elevated total and reduced high density lipoprotein cholesterol level (HDL-C)) and the estimation of 10-year risk of development of CVD (CVD in general, coronary heart disease (CHD), myocardial infarction (MI) and stroke) and that of death from CHD and CVD based on the Framingham Risk Score (FRS) in case of the Hungarian general (HG) and Roma (HR) populations. Methods: A complex health survey incl. questionnaire based interview, physical examination and laboratory test was carried out in 2018 on the HG and HR populations. The prevalence of different cardiovascular risk factors was defined and FRS was computed and compared between the HG (n = 378) and HR (n = 386) populations. Results: The prevalence of diabetes was significantly higher among Roma females compared to females of general population (17.8% vs. 7.7%; p = 0.001) while the average systolic blood pressure level was less elevated among Roma males (127.9 mmHg vs. 129.4 mmHg; p = 0.020). The prevalence of smoking (males: 63.1% vs. 33.7%; females: 67.6% vs. 31%; p < 0.001) and reduced HDL-C level (males: 40% vs. 25.9%, p = 0.014; females: 55.5% vs. 35.1%, p < 0.001) were significantly higher in both sexes among Roma. The 10-year estimated risk for development of CHD, MI and CVD and the death from CHD was significantly (P < 0.05) higher in both sexes among Roma compared to the general population while the average risk scores for stroke and death from CVD were significantly higher only among Roma men. Conclusions: Our results show that both sexes in the Roma population have a significantly higher risk for 10-year development of CVD compared to the Hungarian general population.

Cím:Cut-off values of surrogate indices of insulin resistance as risk predictors for metabolic syndrome / P. Pikó, Sz. Fiatal, Zs. Kósa, J. Sándor, R. Ádány
Dátum:2020
ISSN:1101-1262
Megjegyzések:Background: The metabolic syndrome (MS) based on insulin resistance (IR) is a cluster of conditions indicating an increased risk of cardiometabolic diseases. This study aimed to define valid cut-off values for surrogate measures for IR to predicting the risk for the development of MS in the Hungarian general (HG) and Roma (HR) populations. Methods: This study included 397 HG and 368 HR subjects aged 20-64 years from a complex health survey in 2018/2019. Four surrogate measures, namely the homeostasis model assessment-IR (HOMA-IR), McAuley index (McA), TG to HDL-cholesterol ratio (TG/HDL-C) and TG and glucose index (TyG) were calculated for all participants. The cut-off values were determined as the value with the highest Youden index (YI) on the basis of results obtained by receiver operating characteristic (ROC) curve analysis for the development of MS on separate and combined populations. Results: Since no significant difference could be detected between the results obtained on separate populations, cut-off values defined on the combined one are proposed to use for risk prediction. The area under the ROC curve was 0.753 (95%CI: 0.718-0.787) for HOMA-IR, 0.827 (95%CI: 0.797-0.856) for McA, 0.843 (95%CI: 0.814-0.872) for TG/HDL-C ratio and 0.862 (95%CI: 0.835-0.889) for TyG. The cut-off value was 2.32 (sensitivity (sens.) 70.9%; specificity (spec.) 69.0%; YI: 0.399) for HOMA-IR, 5.989 (sens. 69.7%; spec. 82.7%; YI: 0.524) for McA, 1.274 (sens. 73.4; spec. 84.3%; YI: 0.574) for TG/HDL-C ratio and 4.694 (sens. 77.2%; spec. 84.3%; YI: 0.615) for TyG. Concerning the fact, that the TyG has the best indicative power for predicting IR to the estimation of MS risk in both populations the IR/MS prevalence was defined by using TyG and found to be as high as 42.3% and 40.5% in the HG and HR populations, respectively. Conclusions: Based on our results the TyG index could be a useful supplementary method for identifying individuals at risk for MS.

In our previous study on the prevalence of metabolic syndrome and its components reduced HDL-C level was found significantly more frequent in almost all age groups of the Hungarian Roma compared to the general population (Eur J Public Health 25:299, 2015). This fact in harmony with findings obtained in family and twin studies strongly suggests that plasma level of HDL-C is under genetic control. Our aim was to define whether genetic factors contribute to the higher prevalence of reduced HDL-C level and consequently to the increased susceptibility to atherosclerosis among Roma. Methods SNPs (N = 22) affecting HDL-cholesterol level in genes LIPC(G), CETP, GALNT2, HMGCP, ABCA1, KCTD10 and WWOX were analysed in the Hungarian Roma (N = 757) and general (N = 1787) populations. Genetic risk scores unweighted (GRS) and weighted (wGRS) were calculated and compared within the study populations. In addition the correlation between wGRS and the prevalence of reduced HDL-C level was analysed in both study groups stratified by quintiles. Results Both GRS and wGRS were found significantly higher in Roma than in the general population (GRS: 18.6 3.4 vs. 18.1 3.3, p = 0.001; wGRS: 0.54 0.10 vs. 0.52 0.11, p < 0.001). Only 3% of subjects in the Roma population were in the bottom fifth of the wGRS (wGRS 0.22) compared with 4.8% of those in the general population, while 7% of the Roma subjects were in the top fifth of the wGRS (wGRS 0.7) compared with 3.5% of those in the general population (p = 0.001). Furthermore the prevalence of reduced HDL-C level was significantly higher in the fifth quintile (with the highest genetic load) of the Roma population, than in that of the Hungarian general one (65% vs. 36.3%, p < 0.001). Conclusions The Roma population has increased genetic susceptibility to reduced HDL-C level and consequently to atherosclerosis as it is indicated by higher GRSs values in comparison with that for the general population.

Megjegyzések:Background Large scale association studies that mainly involve European populations identified many genetic loci related to high density lipoprotein cholesterol (HDL-C) levels, the most important indicator of the risk for cardiovascular diseases. Data on non-European populations are just emerging consequently, the generalisability of the association results to non-European populations are pending. We addressed the question whether the individual effect of established HDL-C level related genetic loci are applicable to the Roma population considered to have a South Asian origin. Methods We examined association of 21 SNPs (in genes LIPC(G), CETP, GALNT2, HMGCP, ABCA1, KCTD10 and WWOX) with HDL-C levels by linear regression models using age and sex as covariates. Single SNP associations (direction and magnitude of the effect on HDL-C) were estimated. Analyses were conducted in adults of the Hungarian General (N = 1542) and Hungarian Roma (N = 646) populations. Results The SNPs had small individual effects on HDL-C levels. The beta-coefficients for the general population were found to be identical both in direction and magnitude, indicating that the effect is concordant with large scale studies of European populations obtained previously. Among Roma in case of two SNPs the effect direction, while in case of one SNP the effect size differed in comparison with the general population. Significant associations between SNPs and HDL-C levels were more likely to be seen among general subjects compared to Roma (Roma: 5 SNPs; General: 10 SNPs). The CETP gene variants rs1532624, rs708272 and rs7499892; and the KCTD10 gene rs2338104 variant showed significant associa tions with HDL-C levels consistently in study groups (p < 0.05). Conclusions The patterns of influence of SNPs on HDL-C were consistent across ethnic groups, in large extent, but alteration observed even in effect direction in case of few SNPs indicate that data obtained on European populations can be applied with caution
