Endotoxin-induced microclots in ulcerative colitis and Crohn's disease
Scandinavian Journal of Gastroenterology
|January 1, 1980
Summary
Patients with active Crohn's disease and ulcerative colitis show abnormal fibrin microclots in blood. This fibrin formation, increased by bacterial endotoxins, suggests the presence of circulatory endotoxins in these inflammatory bowel diseases.
Area of Science:
- Gastroenterology
- Hematology
- Immunology
Background:
- Crohn's disease and ulcerative colitis are chronic inflammatory bowel diseases.
- Previous research suggests a link between these conditions and circulatory endotoxins.
Purpose of the Study:
- To investigate the presence of fibrin microclots in patients with active inflammatory bowel disease.
- To determine if bacterial components influence fibrin formation in these patients.
Main Methods:
- Blood samples from patients with active Crohn's disease and ulcerative colitis were incubated in capillary tubes for 24 hours.
- Bacterial extract and endotoxins were added to assess their effect on fibrin formation.
Main Results:
- Radially oriented fibrin microclots were observed in blood from patients with active Crohn's disease and ulcerative colitis.
- Fibrin formation was enhanced by the addition of bacterial extract or endotoxins.
- This phenomenon was absent in healthy individuals and patients with healed disease.
Conclusions:
- The findings support the hypothesis that patients with active Crohn's disease and ulcerative colitis have circulatory endotoxins.
- The observed fibrin microclot formation is a potential indicator of endotoxemia in inflammatory bowel disease.
