Summary
Factor XIIIa levels are significantly lower in active Crohn's disease, correlating with disease severity. Low factor XIIIa may indicate coagulation activation in Crohn's disease pathogenesis.
Area of Science:
- Gastroenterology
- Hematology
- Immunology
Background:
- Factor XIIIa is crucial for stabilizing blood clots by cross-linking fibrin.
- Crohn's disease is a chronic inflammatory bowel disease with complex pathogenesis.
- The role of coagulation factors in inflammatory bowel disease is not fully understood.
Purpose of the Study:
- To investigate plasma concentrations of factor XIIIa in patients with Crohn's disease.
- To explore the relationship between factor XIIIa levels and disease activity.
- To examine the localization of factor XIIIa in inflamed and non-inflamed gut tissue.
Main Methods:
- Prospective study of 16 Crohn's disease patients from relapse to remission.
- Measurement of plasma factor XIIIa concentrations.
- Correlation analysis with Crohn's disease activity index, platelet count, and serum albumin.
- Immunohistochemical staining of gut tissue for factor XIIIa.
Main Results:
- Plasma factor XIIIa concentrations were significantly lower in active Crohn's disease compared to remission (p = 0.002).
- Factor XIIIa levels positively correlated with disease activity index and platelet count, and negatively with serum albumin.
- Factor XIIIa was detected in macrophages and capillary thrombi within the gut wall, including macroscopically normal mucosa.
Conclusions:
- Significantly reduced plasma factor XIIIa in active Crohn's disease suggests a potential role for coagulation activation in its pathogenesis.
- Factor XIIIa localization in gut thrombi indicates localized coagulation events.
- Plasma factor XIIIa concentration may serve as a valuable biomarker for Crohn's disease activity.

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...
01:20Extrinsic and Intrinsic Pathways of Hemostasis
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 forms a...

01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...

01:20Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
