[Blood aggregation in duodenal ulcer]
Insights
Pediatric duodenal ulcers can involve coagulation disorders like disseminated intravascular coagulation (DIC) and Willebrand's disease. Untreated DIC in children with ulcers can worsen bleeding risks.
Area of Science:
- Pediatric Gastroenterology
- Hematology
- Coagulation Science
Context:
- Duodenal ulcers in children present complex hemostatic challenges.
- Accurate assessment of coagulation and platelet function is crucial for effective management.
Purpose:
- To investigate hemostasis in pediatric duodenal ulcer patients using novel synthetic peptide-based coagulologic methods.
- To identify specific hemostatic abnormalities, including disseminated intravascular coagulation (DIC) and other bleeding disorders.
Summary:
- Thirty-six children with duodenal ulcers were evaluated for hemostasis.
- New sensitive synthetic peptide methods allowed for precise analysis.
- Findings revealed compensated DIC in one-third of patients and coagulation disorders like Willebrand's disease and thrombasthenia in four patients.
Impact:
- Coagulologic alterations, particularly compensated DIC, require careful consideration in treatment to prevent hemorrhagic diathesis.
- Understanding these hemostatic issues is vital for managing severe, life-threatening hemorrhages in children with peptic ulcers.
Abstract:
Thirty-six children with duodenal ulcer were examined for the coagulation and thrombocytic components of hemostasis. Use was made of the new coagulologic research methods based on administration of the synthetic tri- and tetrapeptides containing a chromoform group. The high sensitivity of the synthetic peptides enables the use of plasma in high dilutions, owing to which the effect of inhibitors is decreased and a small amount of blood is only required, being of paramount importance in carrying out serial tests. In acute ulcer 1/3 of the children show the signs of the DIC syndrome compensated at the expense of the high content of anticoagulants. At the same time 4 patients were discovered to have coagulologic disorders characteristic of Willebrand's disease (3 cases) and thrombasthenia (1 case). The coagulologic alterations should be taken into consideration in treatment administration, since the compensated DIC syndrome untreated by anticoagulant therapy aggravates the course of the ulcerous process and gives rise to hemorrhagic diathesis. Meanwhile in children with hemorrhagic diathesis, peptic ulcer may cause severe, life-threatening hemorrhages.
