Anticoagulant Drugs: Low-Molecular-Weight Heparins

2.3K
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Venous Thrombosis I: Introduction

639
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Coagulation

11.7K
The coagulation phase is a critical part of the body's process to prevent blood loss following injury to blood vessels. It involves chemical reactions that form a clot to seal the injured area. The clotting process begins shortly after injury, within 15-20 seconds for severe damage and 1-2 minutes for minor injuries.
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...

Coagulation01:06

Coagulation

1.6K
Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

Extrinsic and Intrinsic Pathways of Hemostasis01:20

Extrinsic and Intrinsic Pathways of Hemostasis

14.8K
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...

Area of Science:

  • Hematology
  • Thrombosis Research
  • Coagulation Science

Background:

  • Hypercoagulable states arise from imbalances in coagulation factors, inhibitors, platelets, and endothelium.
  • Thrombosis and embolism are significant clinical outcomes of these imbalances.
  • Congenital deficiencies in coagulation inhibitors are increasingly recognized as key factors in thrombosis, especially in younger individuals.

Purpose of the Study:

  • To investigate the prevalence of inherited thrombophilia in patients presenting with thrombosis.
  • To identify specific coagulation inhibitor deficiencies as causes of thrombosis in a studied cohort.

Main Methods:

  • A cohort of 42 patients with thrombosis, primarily deep vein thrombosis, was analyzed.
  • Standard assay kits were used to evaluate Antithrombin, Protein C, Protein S levels, and activated Protein C resistance.

Main Results:

  • Resistance to activated Protein C was the most frequent finding (n=10), identified as the leading cause of thrombophilia.
  • Deficiencies in Antithrombin (n=4), Protein C (n=3), and Protein S (n=2) were also observed.
  • The majority of thrombosis cases occurred in patients during their third decade of life.

Conclusions:

  • Identifying the specific genetic or acquired cause of thrombophilia is essential for targeted therapy.
  • Understanding the underlying etiology guides patient management strategies for thrombosis prevention and treatment.
