Hypertension III: Clinical Manifestations and Diagnostic Studies

891
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...

Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

3.9K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Type 2 diabetes mellitus develops gradually and is often asymptomatic in early stages.Clinical ManifestationsWhen symptoms appear, they include fatigue, blurred vision, pruritus, delayed wound healing, and recurrent infections, particularly candidal infections. Peripheral neuropathy may present as numbness or tingling in the extremities. Classic hyperglycemia symptoms—polyuria, polydipsia, and polyphagia—are less common. Most patients are overweight and frequently have associated...

Diabetes Mellitus: Type 2 and Gestational

5.0K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Measurement of Blood Pressure01:17

Measurement of Blood Pressure

4.0K
Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Teratogenicity01:07

Teratogenicity

4.2K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

    Summary

    Preeclampsia (PE) prediction is improved by measuring angiogenic factors. Elevated soluble Fms-like tyrosine kinase 1 (sFlt-1) and low Placental growth factor (PIGF) levels can identify high-risk pregnancies, potentially reducing maternal and fetal mortality.

    Area of Science:

    • Obstetrics and Gynecology
    • Maternal-Fetal Medicine
    • Clinical Biochemistry

    Background:

    • Preeclampsia (PE) is a leading cause of pregnancy complications, characterized by hypertension and proteinuria.
    • The exact etiology of PE remains unclear, but anti-angiogenic factors like soluble Fms-like tyrosine kinase 1 (sFlt-1) and low Placental growth factor (PIGF) are implicated.
    • Altered levels of these angiogenic factors precede clinical PE manifestation, suggesting their potential as early diagnostic markers.

    Purpose of the Study:

    • To investigate the diagnostic utility of serum sFlt-1 and PIGF levels in differentiating preeclampsia from other hypertensive disorders in pregnancy.
    • To assess the correlation between angiogenic factor levels and the severity of PE and other pathological pregnancies.

    Main Methods:

    • Serum levels of sFlt-1 and PIGF were measured in 40 pregnant women over two years.

  • Participants were categorized into three groups: preeclampsia (PE), chronic kidney disease (CKD) without hypertension, and normal pregnancy (control).
  • Statistical analysis was performed using parametric Student's t-test with a significance level of p < 0.05.

    • Main Results:

    • Pregnant women with PE exhibited significantly higher sFlt-1 levels (4971.25 pg/ml) compared to controls (3125.53 pg/ml, p < 0.005) and CKD patients (3145.80 pg/ml, p = 0.0032).
    • Conversely, PE patients showed significantly lower PIGF levels (206.63 pg/ml) than controls (667.87 pg/ml, p = 0.0011) and CKD patients (643.13 pg/ml, p = 0.003).
    • These angiogenic factors demonstrated significant differences across the studied groups, indicating potential for diagnostic differentiation.

    Conclusions:

    • Serum sFlt-1 and PIGF levels are significantly altered in preeclampsia, distinguishing it from normal pregnancy and renal disease-related hypertension.
    • Angiogenic factor profiling may serve as a valuable tool for early prediction and differentiation of preeclampsia, potentially improving maternal and fetal outcomes.
    • This study highlights the role of angiogenic imbalance in the pathophysiology of PE, offering insights for improved diagnostic strategies.
