Summary
In children with primary hypertension (PH), elevated inflammatory markers like CRP, MIP-1beta, and RANTES suggest a vascular inflammatory process contributing to target organ damage (TOD). This inflammation may precede broader systemic changes.
Area of Science:
- Pediatric Cardiology
- Inflammation Research
- Vascular Biology
Background:
- Low-grade inflammation is implicated in primary hypertension (PH) and target organ damage (TOD).
- Understanding inflammatory profiles in children with PH is crucial for early intervention.
- Metabolic syndrome (MS) is increasingly recognized in pediatric hypertension.
Purpose of the Study:
- To evaluate the profile of inflammatory mediators in children with untreated PH.
- To investigate the relationship between inflammatory markers, metabolic syndrome, and target organ damage in pediatric PH.
Main Methods:
- Cross-sectional study comparing 44 children with PH to 30 healthy controls.
- Measurement of inflammatory mediators: CRP, RANTES, MIP-1beta, MIP-1alpha, MCP-1, IL-6, angiogenin, adiponectin.
- Assessment of metabolic syndrome criteria, body composition (MRI), carotid intima-media thickness (cIMT), and left ventricular mass index.
Main Results:
- Patients with PH showed higher CRP, MIP-1beta, and RANTES than controls.
- CRP levels correlated with MS criteria, BMI, visceral fat, and cIMT.
- RANTES correlated with lipid profiles; angiogenin correlated with BMI and visceral fat.
- Adiponectin was lower in patients with increased cIMT, suggesting vascular damage.
Conclusions:
- Elevated RANTES and MIP-1beta in pediatric PH suggest a specific vascular inflammatory process.
- CRP elevation and its correlations point to systemic inflammation linked to metabolic alterations and early vascular changes.
- The findings indicate that vascular inflammation may precede systemic inflammatory markers in pediatric PH.

01:18Hypertension and Regulation of Blood Pressure
Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
01:29Hypertension II: Pathophysiology
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
01:28Hypertension I: Introduction
Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...
01:17Antihypertensive Drugs: Action of β1 Blockers
β1-receptors are primarily located in the heart and kidneys. In cardiac myocytes, these receptors interact with neurotransmitters released by the sympathetic nervous system during heightened activity or danger. As a result, β1-receptors get activated, initiating a series of biochemical processes. Excessive activation of beta receptors due to chronic stress can abnormally increase heart rate and contractility, resulting in high blood pressure or hypertension. To counteract this, β1-blockers...
01:30Hypertension III: Clinical Manifestations and Diagnostic Studies
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
01:17Hormonal Regulation of Blood Pressure
Endocrinal or hormonal intervention in the cardiovascular system is predominantly exerted by the catecholamines - epinephrine and norepinephrine, as well as a slew of hormones that interact with renal function to modulate blood volume.
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
