Background: Hypertension (HTN) is associated with subclinical target organ damage including cardiac, vascular and kidney injury. The immune system plays a role in hypertension and target organ damage. Activation of T cells has been reported among peripheral blood mononuclear cells (PBMCs) of patients with HTN. MicroRNAs (miRNAs) are crucial post-transcriptional regulators of immune cells. Whether miRNAs play a role in the activation of immune cells in hypertension complicated by target organ damage in humans remains unknown. We aimed to address this question by identifying differentially expressed (DE) miRNAs and their mRNA targets in PBMCs of patients with hypertension complicated or not with metabolic syndrome (MetS) or chronic kidney disease (CKD). Methods: Normotensive subjects and patients with hypertension (HTN) associated or not with at least 2 other features of MetS or CKD were studied (n=15-16). PBMCs were isolated from blood, RNA extracted for small and total RNA sequencing (RNA-seq) using Illumina HiSeq-2500 and data were analyzed using a systems biology approach. MiRDeep2 was used for novel miRNAs prediction, miRNA annotation and counting. TargetScan 7.07 was used to predict DE miRNA targets with weighted context score percentile >50%. DE genes miRNAs and mRNAs were identified with fold change (FC) >1.5 and P <0.005. DE miRNAs with FC>2 and mean read count number (MRCM) >500, and with predicted targets with MRCM>300 were validated by reverse transcription-quantitative PCR (RT-qPCR). Results: DE miRNAs, mRNAs and non-coding RNAs were identified in HTN (22, 19 and 0), MetS (57, 401 and 11) and CKD (6, 26 and 2) compared to NTN. TargetScan predicted that 7 miRNAs target 3 mRNAs in NTN, 57 miRNAs target 55 mRNAs in MetS and 3 miRNAs target 2 mRNAs in CKD. DE miR-409-5p (FC: 0.54±0.10 vs 1.00±0.09, P <0.05), miR-411-5p (FC: 0.40±0.06, vs 1.00±0.11, P <0.001) and the novel miR-pl-86 (FC: 1.96±0.17 vs 1.00±0.15, P <0.05) in MetS vs NTN were validated by RT-qPCR. RNA-seq data were correlated with RT-qPCR for miR-409-5p (R 2 =0.40, P <2.4E-07, n=55), miR-411-5p (R 2 =0.55, P <1.1E-10, n=55), miR-pl-86 (R 2 =0.37, P <5.5E-07, n=56). Conclusion: This study showed that DE miR-409-5p, miR-411-5p and miR-pl-86 may play a role in HTN associated with MetS.

Aims: to study the target organ damage in patients with metabolic syndrome (MS) and arterial hypertension (AH) 1 degree. Design and methods. We included 20 healthy volunteers and 60 patients with MS, AH 1 degree and dyslipidemia. Office blood pressure, 24-hour ambulatory blood pressure monitoring, measurements of the endothelial vasoactive mediators, carotid ultrasonography and echocardiography had performed at baseline. Results. The majority of patients with MS and AH 1 degree had metabolic abnormalities; the levels of vasoactive mediators were higher in comparison with control group; 30% of patients had signs of atherosclerotic process in carotid arteries; 40% of patients had left ventricular hypertrophy. Conclusion: the results showed high prevalence of target organ damage in patients with MS and AH 1 degree.

AbstractPsychosocial stress relating to an urban environment or acculturation increases the prevalence of metabolic syndrome (MetS). The objectives of this study were firstly to indicate and compare differences regarding appraisal of stress or active coping responses in urban African (n=88) and Caucasian (n=101) male teachers of South Africa, in accord with the prevalence of MetS indicators. And secondly to investigate the extent to which utilisation of active coping responses, together with MetS indicators, predict target organ damage, in these men. The Coping Strategy Indicator determined high and low active coping responses in male teachers from the Sympathetic Activity and Ambulatory Blood Pressure in Africans (SABPA) study. SABPA inclusion and exclusion criteria were used. Additionally, diabetic medication users (n=8), and participants with renal impairment (n=2) or HIV positive (n=13), were excluded. MetS indicators included glucose, triglyceride, high-density lipoprotein cholesterol, blood pressure, and waist circumference, independent of confounders (age, physical activity, gamma glutamyl transferase). Microalbuminuria and carotid intima-media thickness indicated target organ damage. More MetS indicators exceeded the IDF cut-off points in high active coping African men (14.71%) than in their Caucasian counterparts (3.33%), as determined from χ² analyses. Furthermore, stepwise regressions indicated that more MetS indicators predicted endothelial dysfunction, especially in the high active coping African men. High active coping African men showed more manifestation of MetS, compared to their Caucasian counterparts, and revealed progress towards endothelial dysfunction.
