    Insights

    Arterial hypertension, a widespread chronic condition, may be linked to complement dysregulation. New evidence suggests the complement system plays a crucial role in hypertension development and progression.

    Area of Science:

    • Nephrology
    • Immunology
    • Cardiovascular Medicine

    Background:

    • Arterial hypertension is a prevalent global chronic disease affecting one-third of adults, projected to be the most common by 2025.
    • Despite extensive research into risk factors, the exact cause of hypertension remains unknown.
    • Hypertension requires lifelong management without distinct attacks or remissions.

    Purpose of the Study:

    • To investigate the role of the complement system in the pathogenesis of arterial hypertension.
    • To explore the connection between complement dysregulation and conditions like atypical hemolytic-uremic syndrome in malignant hypertension.

    Main Methods:

    • Review of recent experimental data on complement's involvement in hypertension.
    • Analysis of evidence linking thrombotic microangiopathy in malignant hypertension to atypical hemolytic-uremic syndrome.

    Main Results:

    • Experimental data strongly implicate the complement system in all stages of arterial hypertension.
    • A significant subset of malignant hypertension cases are manifestations of atypical hemolytic-uremic syndrome, indicating complement dysregulation.

    Conclusions:

    • Complement dysregulation is a key factor in a substantial proportion of hypertension cases.
    • The complement system's role in hypertension is more significant than previously understood, necessitating a shift in perspective.

    Hypertension and Regulation of Blood Pressure01:18

    Hypertension 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...

    Disorders of the Autonomic Nervous System

    The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

    Antihypertensive Drugs: Angiotensin II Receptor Blockers

    In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...

    Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors

    Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...

    Antihypertensive 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,...
