AI Article Synopsis

  • This study explored the link between specific genetic variations in the renin-angiotensin system and essential hypertension in people from Burkina Faso, using a case-control design with 202 hypertensive patients and 204 matched controls.
  • The research found that while two polymorphisms (AGT 235M/T and AT1R 1166A/C) showed no association with hypertension, the ACE I/D polymorphism had significantly different genotype frequencies between the groups, with the DD genotype being more prevalent in hypertensive patients.
  • Key risk factors identified included the DD genotype of the ACE gene, older age, obesity, dyslipidemia, and alcohol consumption, indicating that the DD genotype is a significant predictor of hypertension susceptibility.

Article Abstract

Objective. This study aimed to investigate the association between three polymorphisms of renin-angiotensin system and the essential hypertension in the population of Burkina Faso. Methodology. This was a case-control study including 202 cases and 204 matched controls subjects. The polymorphisms were identified by a classical and a real-time PCR. Results. The AGT 235M/T and AT1R 1166A/C polymorphisms were not associated with the hypertension while the genotype frequencies of the ACE I/D polymorphism between patients and controls (DD: 66.83% and 35.78%, ID: 28.22% and 50.98%, II: 4.95% and 13.24%, resp.) were significantly different (p < 10(-4)). The genotype DD of ACE gene (OR = 3.40, p < 0.0001), the increasing age (OR = 3.83, p < 0.0001), obesity (OR = 4.84, p < 0.0001), dyslipidemia (OR = 3.43, p = 0.021), and alcohol intake (OR = 2.76, p < 0.0001) were identified as the independent risk factors for hypertension by multinomial logistic regression. Conclusion. The DD genotype of the ACE gene is involved in susceptibility to hypertension. Further investigations are needed to better monitor and provide individualized care for hypertensive patients.

Diabetic kidney disease is a leading cause of kidney failure worldwide and is easily detectable with screening examination. Diabetes causes hyperfiltration and activation of the renin-angiotensin aldosterone system by hemodynamic changes within the nephron, which perpetuates damaging physiology. Diagnosis is often clinical after detection of heavy proteinuria in a patient with diabetes,but can be confirmed by observation of histologic stages on kidney biopsy.

The renin-angiotensin-aldosterone system (RAAS) is a complex regulator comprising hormones, proteins, and enzymes. The discovery of the RAAS and its pharmacological manipulation has been essential in the management of cardiovascular diseases, including hypertension. Beyond the benefits of hypertension, RAAS inhibition has implications for heart failure, atherosclerotic disease, and kidney disease.

Patient-specific premorbidity, age, and sex are significant heterogeneous factors that influence the severe manifestation of lung diseases, including COVID-19 fibrosis. The renin-angiotensin system (RAS) plays a prominent role in regulating the effects of these factors. Recent evidence shows patient-specific alterations of RAS peptide homeostasis concentrations with premorbidity and the expression level of angiotensin-converting enzyme 2 (ACE2) during COVID-19.

The role of the intrarenal renin-angiotensin system (iRAS) in diabetic kidney disease (DKD) progression remains unclear. In this study, we generated mice with renal tubule-specific deletion of angiotensinogen (Agt; RT-Agt-/-) in both Akita and streptozotocin (STZ)-induced mouse model of diabetes. Both Akita RT-Agt-/- and STZ-RT-Agt-/- mice exhibited significant attenuation of glomerular hyperfiltration, urinary albumin/creatinine ratio, glomerulomegaly and tubular injury.

Background: Angiotensin-converting enzyme (ACE) is a validated risk locus for developing late-onset Alzheimer's disease (LOAD). ACE1 controls blood pressure through the renin-angiotensin system (RAS), but it is also present and acts locally in the brain. Hypertension is associated with an increased risk for developing AD, and people taking select RAS-targeting therapeutics have reduced incidence of AD.
