Disorders of Hemostasis01:24

Disorders of Hemostasis

1.0K
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.

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...

Introduction to Hemostasis

Hemostasis is a complex physiological process that prevents excessive bleeding when a blood vessel is injured. It's crucial for maintaining the integrity of the circulatory system, as it ensures that our blood remains fluid while still within the vascular network and yet clots to prevent blood loss upon vessel injury.
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized,...

Extrinsic and Intrinsic Pathways of Hemostasis

8.6K
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 platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Summary

People with mild hemophilia often develop joint damage (arthropathy) due to bleeds, significantly impacting their quality of life. Early diagnosis and treatment are crucial for managing this condition.

Area of Science:

  • Orthopedics
  • Hematology
  • Quality of Life Research

Background:

  • Mild hemophilia (PWMH) patients face diagnostic delays and inadequate care, leading to joint complications.
  • Arthropathy significantly impairs health-related quality of life (QoL) in PWMH, causing pain and mobility issues.

Purpose of the Study:

  • To determine the incidence, risk factors, and QoL impact of arthropathy in people with mild hemophilia.
  • To evaluate joint health using clinical, ultrasound, and radiological assessments.

Main Methods:

  • An observational, cross-sectional cohort study involving 85 patients and 510 joints.
  • Utilized Haemophilia Joint Health Score (HJHS), HEAD-US, Pettersson score (PS), VAS for pain, and QoL evaluations.
  • Defined arthropathy as a HEAD-US score ≥ 1 in any joint.

Main Results:

  • 72% of patients had arthropathy (HEAD-US ≥ 1), with the ankle being the most affected joint.
  • Patient age was the primary risk factor for arthropathy development (median age 44.2 with arthropathy vs. 14.9 without).
  • 90.5% of patients over 20 years old exhibited arthropathy.

Conclusions:

  • Joint damage from hemarthrosis is strongly linked to reduced QoL in PWMH.
  • Emphasizes the critical need for early diagnosis and proactive management of arthropathy in this population.
