Anticoagulant Drugs: Low-Molecular-Weight Heparins

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...

Extrinsic and Intrinsic Pathways of Hemostasis

6.7K
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...

The Chinese Haemophilia Individualized Prophylaxis Study (CHIPS) demonstrated long-term efficacy in reducing haemarthrosis in severe haemophilia A (SHA) patients. This approach also preserved joint health and improved quality of life, showing significant cost savings.

Area of Science:

  • Paediatric Hematology
  • Bleeding Disorders
  • Clinical Research

Background:

  • The Chinese Haemophilia Individualized Prophylaxis Study (CHIPS) initially showed reduced haemarthrosis in severe haemophilia A (SHA) patients over one year.
  • Long-term efficacy of the CHIPS protocol required further investigation.

Purpose of the Study:

  • To evaluate the long-term clinical outcomes of SHA patients following the CHIPS protocol.
  • To assess the sustained efficacy of individualized prophylaxis in managing haemophilia A.

Main Methods:

  • Follow-up of 18 SHA patients for three years post-initial CHIPS study.
  • Serial ultrasound examinations of index joints every six months.
  • Escalation of treatment based on index joint bleeding events.

Main Results:

  • Significant reduction in mean annual bleeding rates (from 18.9 to 1.7) and annual joint bleeding rates (from 3.1 to 1.2).
  • Resolution of 5 out of 8 target joints; 16 treatment escalations occurred.
  • Improved quality of life scores (CHO-KLAT) and cost savings observed, despite no change in ultrasound scores.

Conclusions:

  • The CHIPS protocol provides long-term efficacy in reducing haemarthrosis for SHA patients.
  • Individualized prophylaxis preserves joint health and enhances quality of life.
  • The CHIPS approach demonstrates cost-effectiveness in managing severe haemophilia A.
