    Insights

    Hypertension is common in hemolytic uremic syndrome (HUS), particularly in children with vascular thrombotic microangiopathy (TMA). Bilateral nephrectomy effectively treated hypertension, highlighting hyperreninemia

    Area of Science:

    • Nephrology
    • Pediatric Nephrology
    • Pathology

    Context:

    • Hemolytic uremic syndrome (HUS) is a serious condition affecting infants and children.
    • Hypertension is a significant complication of HUS, impacting patient outcomes.
    • Understanding the pathophysiology of HUS-associated hypertension is crucial for effective management.

    Purpose:

    • To evaluate the incidence and patterns of hypertension in pediatric patients with HUS.
    • To correlate clinicopathological findings with the severity of hypertension in HUS.
    • To investigate the role of hyperreninemia in HUS-induced hypertension.

    Summary:

    • This study reviewed 70 patients with HUS, analyzing hypertension incidence and histopathological findings.
    • Refractory hypertension was more prevalent in children than infants, predominantly associated with vascular thrombotic microangiopathy (TMA).
    • Bilateral nephrectomy rapidly resolved hypertension, supporting the role of hyperreninemia in HUS-related hypertension.

    Impact:

    • Provides critical insights into the clinical spectrum of hypertension in HUS.
    • Highlights the importance of histopathological classification (vascular TMA) for predicting severe hypertension.
    • Demonstrates the therapeutic efficacy of nephrectomy in severe HUS-associated hypertension, implicating hyperreninemia.

    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...

    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...

    Blood Pressure Imbalances and Circulatory Shock

    Disorders affecting blood volume, vascular tone, or vascular function can disrupt vascular homeostasis, including conditions like hypertension, hemorrhage, and shock.
    Blood Pressure: Hypertension and Hypotension
    Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...

    Hypertension 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,...

    Nephrotic Syndrome I : Introduction

    Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of fluid...

    Chronic Kidney Disease II: Clinical Manifestations

    Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...
