    Insights

    Patients with hypertensive chronic glomerulonephritis (CGN) exhibit disrupted daily arterial pressure (AP) rhythms, with higher nighttime pressure loads compared to essential arterial hypertension (EAH). This highlights significant cardiovascular differences in CGN patients.

    Area of Science:

    • Nephrology
    • Cardiology
    • Hypertension Research

    Background:

    • Chronic glomerulonephritis (CGN) can lead to secondary hypertension.
    • Essential arterial hypertension (EAH) serves as a comparator for understanding hypertensive CGN.
    • Preserved renal function in CGN patients allows focus on AP dynamics.

    Purpose of the Study:

    • To compare daily arterial pressure (AP) dynamics in patients with hypertensive CGN and EAH.
    • To investigate disturbances in diurnal AP rhythm in hypertensive CGN.
    • To identify specific AP variability patterns associated with hypertensive CGN.

    Main Methods:

    • Ambulatory arterial pressure (AP) monitoring in 136 hypertensive CGN patients and 49 EAH patients.
    • Analysis of diurnal AP dynamics including mean pressures, variability, and rhythm.
    • Clinical, laboratory, instrumental, and morphological (nephrobiopsy) verification of CGN diagnosis.

    Main Results:

    • Hypertensive CGN patients showed elevated daytime and nighttime AP.
    • Daily AP rhythm was significantly more disturbed in hypertensive CGN than in EAH.
    • Nighttime hypertension occurred in 27% of CGN patients versus 9% in EAH.
    • Inadequate nocturnal AP fall was observed in 53% of CGN patients.

    Conclusions:

    • Hypertensive CGN is associated with significant disruptions in daily AP rhythm and increased nighttime pressure load.
    • CGN-related hypertension exhibits distinct diurnal AP patterns compared to EAH.
    • These findings underscore the need for tailored antihypertensive strategies in hypertensive CGN.

    Glomerular Filtration Rate and its Regulation01:28

    Glomerular Filtration Rate and its Regulation

    The Glomerular Filtration Rate (GFR) is a measure of kidney function, reflecting the volume of filtrate formed per minute in the kidneys. On average, GFR is approximately 125 mL/min in males and 105 mL/min in females. Maintaining a relatively constant GFR is essential for the kidneys to effectively regulate body fluid homeostasis and maintain extracellular stability.
    GFR regulation involves two primary intrinsic controls: the myogenic and tubuloglomerular feedback mechanisms.
    The myogenic...

    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...

    Diabetic Nephropathy

    Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...

    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 Diuretics

    Diuretics are antihypertensive drugs used to treat hypertension resulting from sodium and water retention. Sodium, vital for fluid balance and nerve or muscle function, is regulated by the kidneys through millions of nephrons. Blood enters nephrons via afferent arterioles, which branch into capillaries called glomeruli. These filter blood plasma, allowing water and solutes, like sodium ions, to pass through capillary walls into Bowman's capsule. The filtrate then flows through various tubules...
    Blood Pressure01:30

    Blood Pressure

    Blood pressure (BP) is the pressure or force of blood exerted on the artery's walls as it circulates through the body. It is essential for maintaining blood flow throughout the body.
    The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
