Abstract
Background: Aldosterone synthase (CYP11B2) is crucial for aldosterone production, and variations in its gene may influence type 2 diabetes mellitus (T2DM) development. This study explores the link between two single nucleotide polymorphisms (SNPs) in the CYP11B2 gene - -344T/C and K173R and T2DM in the Moroccan population . Methods: The research involved 86 individuals with T2DM and 75 control subjects. Genotyping for the -344T/C and K173R SNPs was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis . Result: Results indicated significant differences in the genotype and allelic distribution of the CYP11B2 K173R polymorphism between T2DM patients and control subjects, with P-values of 0.02 and 0.04, respectively. The -344T/C polymorphism showed no significant genomic level differences, but its allelic variations were statistically significant (P=0.01), indicating a notable association between the C allele and T2DM. Furthermore, the K173R polymorphism was found to significantly increase T2DM risk, with a 2.34-fold higher risk in individuals carrying the KR genotype. The study also examined the combined effect of these SNPs. The dominant model analysis (TT vs. TC+CC and KK vs. KR+RR) showed significant differences between T2DM patients and controls for both SNPs. Additionally, a haplotype-based analysis revealed that the C-R haplotype was associated with an increased risk of T2DM. Conclusion: Our study suggests a significant association between the CYP11B2-K173R polymorphism and T2DM in the Moroccan population. Conversely, while the CYP11B2 -344T/C polymorphism exhibits a significant difference in allelic distribution, no significant difference is observed at the genomic level.

Abstract
Abstract
Objective. The aim of present study was to analyze the serum lipid profile parameters in patients with type 2 diabetes mellitus (T2DM) and comorbidities [overweight/obesity and/or chronic pancreatitis (CP)] to determine the contribution of these pathologic factors to lipid metabolism disorders in T2DM.
Methods. The study involved 579 type 2 diabetic (T2D) patients with comorbid overweight/ obesity and/or CP. The serum lipid panel parameters [total cholesterol (TC), triglycerides (TG), and high-density lipoprotein cholesterol (HDL-C)] were determined by commercially available kits on a Cobas 6000 analyzer (Roche Hitachi, Germany). Low-density lipoprotein cholesterol (LDL-C), non-HDL-C, and remnant cholesterol (RC) levels were calculated using formulas. The data were statistically analyzed using STATISTICA 7.0.
Results. It was shown that dyslipidemia in T2D patients is characterized by unidirectional changes regardless the presence/absence of comorbid overweight/obesity or CP. At the same time, the most severe dyslipidemia was detected in T2D patients with a combination of comorbid over-weight/obesity and CP. Both the elevated body mass index (BMI) and CP can aggravate lipid metabolism disorders in T2DM. In our study, however, the BMI increase positively correlated with the number of dyslipidemia patients characterized by exceeding all target lipid levels for diabetic patients. This is in contrast to T2D patients with normal body weight and comorbid CP, in whom only LDL-C and TG exceeded the target lipid levels.
Conclusions. A combination of comorbidities, such as obesity and CP in T2D patients, produced a mutually aggravating course defined particularly by common pathogenic links, insulin resistance, chronic generalized low-intensity inflammation, endothelial dysfunction, and dyslipidemia caused primarily by triglyceridemia.

Abstract
Objective. The aim of the present study was to clarify the endothelial function biomarkers and carotid "intima media" thickness (IMT) changes in relation to GNB3 (rs5443) and NOS3 (rs2070744) genes polymorphism in the essential arterial hypertension (EAH). Methods. One-hundred EAH patients (48 - control) participated in the case-control study. Soluble vascular cell adhesion molecule (sVCAM-1), total NO metabolites (NO2 -+NO3 -), transcriptional activity of NOS3 gene, endothelium-dependent flow-mediated dilation of the brachial artery (FMD BA), and carotid IMT were studied. GNB3 (rs5443) and NOS3 (rs2070744) genotyping was performed by TaqMan probes (CFX96™Real-Time PCR). Results. The connection of NOS3 (rs2070744) with decreased total NO metabolites (F=71.11; p<0.001), reduced NOS3 genes transcription activity (F=8.71; p<0.001) and increased sVCAM-1 (F=6.96; p=0.002), especially in the C-allele carriers (particularly in CC-genotype patients with lower NO - 16.46% and 40.88%; p<0.001), lowered the transcription activity of NOS3 gene - 46.03% 7 times (p<0.001), and become higher sVCAM-1 - 35.48% and 89.48% (p<0.001), respectively. ANOVA did not confirm the association of GNB3 (rs5443) gene with endothelial function and carotid IMT. Severe EAH was associated with increased carotid IMT - 50.0% (p<0.001) and 57.14% (p=0.007), wider carotid arteries - 17.36% (p=0.012) and 21.79% (p=0.004), and decreased NOS3 genes transcription activity - 34.54% (p=0.003). Atherosclerotic plaques were unilateral - 24.77% (χ2=5.35; p=0.021) or bilateral - 27.62% (χ2=5.79; p=0.016). IMT---gt---0.9 mm was followed by a higher BP (p<0.001), FMD BA 11.80% decrease with compensatory increase in carotid arteries diameters - 17.38% and 21.99% (p<0.001) and sVCAM-1 by 20.49% (p=0.005). Conclusion. NOS3 (rs2070744), but not GNB3 (rs5443), gene associated with the essential arterial hypertension severity relying upon the endothelial function impairment and NOS3 genes reduced transcription activity.

Abstract
Early diagnosis of essential arterial hypertension (EAH), the search for risk factors for its occurrence and severity, which determine the metabolome and epigenetic structures activity, is an urgent task of modern medicine.
The objective: to assess the risks of metabolic disorders and the EAH occurrence, depending on the NOS3 (rs2070744) and GNB3 (rs5443) genes’ allelic state.
Materials and methods. 100 patients with EAH and 48 practically healthy (control group) were enrolled in the study. All participant underwent clinical and laboratory examinations. Metabolic changes were examined by blood glucose, total cholesterol (TC), triacylglycerol (TG), high and low density lipoprotein cholesterol (HDL-C, LDL-C), Atherogenicity index (AI). The NOS3 (rs2070744) and GNB3 (rs5443) genes were studied by real-time PCR. Risks, prognoses were determined by the clinical epidemiology method.
Results. The risk of metabolic disorders (dyslipidemia and hyperglycemia) in EAH patients does not depend on NOS3 gene polymorphism (rs2070744). However, the mutational T-allele of the GNB3 gene (825C>T) presence in the patients’ genotype increases the risk of hyperlipidemia due to atherogenic LDL-C 8.5 times [OR=8.45; OR 95%CI:0.99–72.70; p=0.05], with the CC-genotype protective role [OR=0.12; OR 95%CI:0.01–1.0; p=0.048].
The overall risk of EAH in the examined population increases with fasting hyperglycemia 9 times [OR 95%CI:2.86–27.08; p<0.001], with hypertriglyceridemia (>1.70 mmol/l) – 3 times [OR 95%CI:1.23–5.56; p=0.009] and with a decrease in HDL-C (<1.2 mmol/l) – more than 3.5 times [OR 95%CI:1.46–8.71; p=0.003], respectively.
Conclusion. The risk of metabolic disorders increases in EAH patients with the T-allele of the GNB3 gene (825C>T) 8.5 times with the lowest probability of such changes in the CC-genotype carriers [OR=0.12; p=0.048].

Abstract
BACKGROUND: Cardiovascular (CV) diseases are the most spread cause of mortality in the world. Essential arterial hypertension (EAH), as a major risk factor for the development of CV diseases, is a multifactorial disease involving environmental and genetic factors together with risk-conferring behaviors.
AIM: The purpose of this study was to analyze lipid metabolism changes in patients with EAH depending on the Vitamin D receptor (VDR rs2228570 (aka rs10735810)) and angiotensinogen (AGT rs699) genes polymorphism.
MATERIALS AND METHODS: The single-stage study involved 100 patients suffering from Stage 2 EAH, 1–3 degrees of blood pressure increase, high and very high CV risks, 21% (21) men, and 79% (79) women. The average age of patients was 59.86 ± 6.22 years old. The control group included 60 practically healthy individuals of an appropriate age and sex distribution. To examine the VDR gene (rs10735810, rs2228570) and AGT gene (rs699) polymorphism, a qualitative real-time polymerase chain reaction was made. The lipid metabolism was studied by determining the blood plasma content of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TGs).
RESULTS: Т allele of AGT gene is associated with reduced HDL-C level in men and increased TGs level in women. The EAH risk increases 4.5 times as much among the ТС-genotype carriers and lowered HDL-C level (odds ratio [OR] = 6.43; p = 0.01). The EAH risk increases as far as the HDL-C level reduction, irrespective of the VDR gene alleles condition 1.83 times (OR = 2.37; OR 95% confidence interval [CI]: 1.02–5.51; p = 0.04) and 1.9 times (OR=2.43; OR 95% CI: 0.99–5.97; p = 0.04). HDL-C reduction and LDL-C elevation in women increase the EAH risk 2.4 times (OR = 3.27; p = 0.01) and 1.24 times (OR = 3.67; p = 0.01), respectively.
CONCLUSIONS: The EAH risk increases with a reduced HDL-C level in the TC genotype carriers of the AGT gene and irrespective of VDR gene polymorphic variants.

Abstract
BACKGROUND This study investigated the association of angiotensin-converting enzyme (ACE I/D) and aldosterone synthase (CYP11B2-344C/T) gene polymorphisms in the renin-angiotensin-aldosterone system (RAAS) with atrial fibrillation (AF) in the Tunisian population. MATERIALS AND METHODS The study population included 120 patients with AF and 123 age-matched controls. Genotyping of the I/D polymorphism in the ACE gene and the -344C/T polymorphism in the CYP11B2 gene was performed by polymerase chain reaction (PCR) and PCR-RFLP methods, respectively. RESULTS The genotype distribution of the ACE I/D and CYP11B2-344C/T polymorphisms was significantly different between AF patients and control participants (p < 0.01 and p < 0.006 respectively). In addition, ACE I/D increased the risk of AF significantly by 3.41-fold for the DD genotype (OR = 3.41; 95% CI [1.39-8.34]; p < 0.007), and after adjusting for confounding factors (age, diabetes, hypertension, and dyslipidemia), the risk was higher (OR = 5.71; 95% CI [1.48-21.98]; p < 0.01). Likewise, the CYP11B2-344C/T polymorphism increased the incidence of AF for the TT genotype (OR = 3.66; 95% CI [1.62-8.27]; p < 0.002) and the CT genotype (OR = 2.68; 95% CI [1.22-5.86]; p < 0.01). After adjusting for confounding factors (age, diabetes, hypertension and dyslipidemia), the risk remained higher for the TT genotype (OR = 3.58; 95% CI [1.08-11.77]; p < 0.03). Furthermore, the haplotype-based association of the ACE I/D and CYP11B2-344C/T polymorphisms showed that the D-T haplotype increased the risk for AF. CONCLUSION Our study suggests a significant association of the ACE (I/D) and CYP11B2-344C/T polymorphisms with AF in the Tunisian population.

Abstract
Essential arterial hypertension (EAH) is a polygenic disease due to environmental, genetic, and epigenomic factors. The study aimed to establish the association of single nucleotide polymorphism (SNP) of AGTR1 (rs5186) and VDR (rs2228570) genes with the blood pressure (BP) elevation in EAH patients. 100 EAH subjects with hypertensive-mediated organ damaging (2nd stage), moderate, high, or very high cardiovascular risk were recruited into the case-control study. There were 70.83% females and 29.17% males, mean age 57.86±7.81 y.o. The control group included 60 healthy individuals of relevant age and gender distribution. Estimation of AGTR1 (rs5186) and VDR (rs2228570) gene polymorphism was performed by Real-Time Polymerase Chain Reaction. In EAH patients, the AGTR1 gene (rs5186) mutation occurs with a frequency of 2.78% in the absence of such among healthy individuals. The VDR (rs2228570) gene mutation occurs with a frequency of 23% cases. The C-allele carriers’ (AGTR1 gene) numbers with 2nd and 3rd BP values degree dominate over AA-genotype patients by 25.32% (χ2=4.52; p=0.033). VDR gene (rs2228570) polymorphic variants do not link to BP elevation values. Thus, the C-allele of the AGTR1 gene (rs5186) is associated with BP elevation in hypertensive patients. BP values do not depend on VDR gene (rs2228570) polymorphic variants.
