Abstract
The objective of this study was to examine frequency of familial defective apo-B-100 (FDB, R3500Q mutation) in probands with the phenotype of familial hypercholesterolemia (FH) and in the general population of 40-year-old subjects in Slovakia and to characterize their lipid and clinical criteria and to compare the frequency of FDB with other populations. We identified 35 patients with FDB among 362 probands with clinical diagnosis of FH and two cases of FDB in the 40-year-old cohort of 2323 subjects from general Slovak population. Probands with FDB differed from those with FH only in plasma triglyceride concentrations (1.84+/-1.4 mmol/l versus 1.45+/-0.98 mmol/l, respectively, p<0.01). Evaluation of personal history of premature atherosclerosis did not show any differences (11.4% in FDB versus 20% in FH, p<0.16). The FDB patients had similar manifestation of xanthomatosis as the FH patients (17.1% versus 8.25%, p<0.25). The frequency of FDB of 9.7% found in the FH patients is among the highest of those reported to date. The frequency of R3500Q mutation of 0.09% found in Slovak 40-year-old subjects did not differ significantly from published population molecular data. Our comparison of estimated FDB frequencies with those which were found by DNA analysis demonstrated that estimated frequencies were not only wider in range, but also significantly higher than those which were assessed by the analysis. The definitive answer to the prevalence of FDB and its biochemical and clinical characteristics requires screening of unbiased samples of the general population from different ethnic groups based on molecular genetic methods.

Abstract
The influence of apolipoprotein E (ApoE) genotypes on plasma lipid levels and interaction with other environmental factors was determined in two Slovakian population samples; 146 Romany and 351 Slovak individuals. The two samples differ significantly in the distribution of E3/3 genotypes (p<0.014) and E3/2 (p<0.035). Analysis of variance did not reveal any significant effect of the ApoE genotypes on any of the plasma lipid levels in the Romany individuals. In the Slovak sample the variation in plasma low-density lipoprotein cholesterol (LDL-C) levels was significantly associated with the ApoE genotypes (p=0.012). We detected decreased LDL-C concentrations in males with E2 genotype when compared with E3 and E4 carriers (p=0.008). Further, the E2 genotype was found to be associated with high triglycerides levels (p=0.009). The ethnic samples differ significantly in the prevalence of metabolic syndrome and in the case of males of diabetes. Both the Romany and the Slovak males can be considered as having a more atherogenic profile compared with the females.

Abstract
The objective of this study was to examine plasma homocysteine levels and C677T methylenetetrahydrofolate reductase (MTHFR) gene polymorphism in two ethnic groups from Slovakia. The samples consisted of general Slovak-Romany population (68 men and 81 women) from Southwestern Slovakia and the Slovak-Caucasians (174 men and 177 women) who participated in the CINDI project. The homocysteine levels were examined by HPLC, the analysis of MTHFR genotypes was done by PCR. The Slovak-Romany men (12.0+/-5.6 (S.D.) micromol/l) and women (9.2+/-2.6 microol/l) have significantly lower plasma homocysteine levels (p<0.024 and p<0.00001) when compared to Caucasians (13.3+/-5.1 micromol/l in men and 11.3+/-4.3 micromol/l in women). The genetic equilibrium is assumed for the gene frequencies of the MTHFR polymorphism in both samples. The distribution of MTHFR genotypes did not differ between the two populations (TT 13 vs. 10.6 %; CT 46.6 vs. 41.7 %; CC 40.4 vs. 47.7 %, chí(2)2 = 2.315, df=2, ns). The effect of MTHFR genotypes on homocysteine levels was not confirmed in the Slovak-Romanies and TT homozygosity significantly increased plasma homocysteine levels only in Slovak-Caucasians (11.5+/-4.4 micromol/l, ns; vs. 14.8+/-4.8 micromol/l, p 0.002, respectively). To our knowledge, this is the first epidemiological study in the Romany population examining distribution of the MTHFR genotypes and their effect on homocysteine levels. Further studies are needed to establish the variety of cardiovascular risk factors among Romanies in order to evaluate the significance of particular factors.

Abstract
We examined, from a cohort of 165 families, 529 individuals for familial hypercholesterolemia (FH). Utilising clinical criteria for diagnosis, we identified 122 patients (n=41 families) as having FH. With PCR testing, 31 individuals (n=12 families) were found to have familial defective Apo B-100 (FDB). From the cohort, 102 normolipidemic (NL) individuals served as a control group. Patients with FH had the highest levels of total cholesterol (TC), LDL-cholesterol (LDL-C) and apolipoprotein B (Apo B), followed by FDB patients and the normolipidemic relatives had the lowest levels (P<0.0001 for all parameters). We did not find any effect of Apo E genotypes on lipid levels in the NL or FH group. Therefore, other genetic and/or environmental factors may be responsible for the diversity in the clinical expression in these populations.

Abstract
Glutathione S-transferase genotypes GSTT1, GSTM1, GSTP1 were characterised in 155 middle-aged men and compared with parameters of oxidative stress at the level of DNA and lipids, with antioxidant enzymes, and with plasma antioxidants in smokers and non-smokers. Smokers had on average significantly lower levels of Vitamin C, beta-carotene and beta-cryptoxanthin and higher amounts of oxidised purines and pyrimidines in lymphocyte DNA. The GSTM1 null genotype was associated with elevated glutathione as well as with higher Vitamin C concentration in plasma. Vitamin C was higher in GSTT1+ compared with GSTT1 null--as was glucose-6-phosphate dehydrogenase activity. The homozygous GSTP1 a/a genotype was associated with significantly higher levels of GST activity measured in lymphocytes, in comparison with the b/b genotype. Using multifactorial statistical analysis we found significant associations between smoking, GSTP1 genotype, plasma Vitamin C, and purine base damage in lymphocyte DNA. The difference in Vitamin C plasma levels between smokers and non-smokers was seen only with the GSTP1 b/b genotype. This group accounted also for most of the increase in purine oxidation in smokers. In contrast, the link between smoking and oxidised pyrimidines in DNA was seen only in the GSTT1 null group. It seems that polymorphisms in the phase II metabolising enzyme glutathione S-transferase may be important determinants of commonly measured biomarkers.

Abstract
The objective of this study was to evaluate the effect of diet and 677 C-->T mutation of the methylenetetrahydrofolate reductase (MTHFR) gene on plasma homocyst(e)ine concentrations in an adolescent population (113 males, age: 14.2+/-2.4 years; 202 females, age: 14.9+/-2.1 years) from a region characterized by high cardiovascular mortality. Homocyst(e)ine levels did not differ between males and females (9.4+/-3.5 and 8.9+/-3.1 micromol/l, respectively). The homozygosity for the 677 C-->T MTHFR mutation was found in 4.6 % of subjects. No differences in homocyst(e)ine levels were found between MTHFR genotypes. Analysis of the diet composition which was performed on a 24-hour daily recall basis and a food frequency questionnaire showed a low daily intake of vitamin B6 (males: 1.13 mg/66% RDA; females: 0.92 mg/61% RDA). Daily folic acid intake was 0.21 g/105% RDA in males and 0.23 g/115% RDA in females. The results of our study show that the high homocyst(e)ine levels in the adolescent population were not affected by the 677 C-->T MTHFR mutation. We conclude that an insufficient dietary intake of vitamin B6 and folic acid is responsible for this finding. This is in accord with the recommendation that the dietary allowances for folate should be reset to the originally prescribed levels of 0.4 g/day which should be sufficient to control the homocysteine levels.

Abstract
To explore the hypothesis that an interplay between genetic and environmental factors contributes to the development of coronary atherosclerosis, we compared the prevalence of risk factors for atherosclerosis among survivors of myocardial infarction (MI) and their spouses and apparently healthy men and women (spousal pairs) with no personal and family history of atherosclerosis in three generations. There were no significant differences in life-style and dietary habits between the groups. The daily vegetable and/or fruit intake was generally low and did not differ between the groups. Thirty percent and 25% of men and women did not consume any vegetables or fruits, respectively. All differences found in the male MI survivors and control men were also found between the female groups: MI survivors and their spouses were significantly more obese and had higher systolic and diastolic blood pressure and more pathologic plasma lipid levels compared with control males and females, respectively. Compared with the control men and women, MI survivors and spouses had higher plasma homocysteine (Hcgamma) levels (15.3 +/- 10.5, 11.9 +/- 4.0, 16.9 +/- 5.5, and 14.3 +/- 4.0, micromol/L, respectively, P = .01). The frequency of the homozygous C677T 5,10-methylenetetrahydrofolate reductase (MTHFR) polymorphism in MI survivors was twice that observed in their spouses and controls (12.1%, 4.8%, and 5.8%, respectively), but this difference did not reach statistical significance. A statistically significant association of the MTHFR genotype and Hcgamma concentration (multiple ANOVA) was shown. Neither the frequencies of apolipoprotein E (apoE) alleles nor Asp9Asn mutation of exon 2, Asn29lSer mutation of exon 6, and Ser447Ter of exon 9 of the lipoprotein lipase (LPL) gene varied significantly among the groups. A possible explanation for our findings is that individuals with a genetic predisposition for atherosclerosis and their spouses share a life-style that results in a higher body mass index (BMI) and waist to hip ratio (WHR). On the other hand, individuals with no family history of atherosclerosis, despite an unhealthy life-style similar to that in the affected families (diet and physical activity), had a lower BMI and WHR and more favorable metabolic parameters, including plasma Hcgamma. In conclusion, we have shown that a personal and/or family history of atherosclerosis corresponds to the prevalence and level of risk factors for atherosclerosis. A combination of life-style factors and inherited metabolic abnormalities, including high plasma Hcgamma, are the more likely explanation for our findings.
