Dino Mehic: Can Global Coagulation Testing Detect Abnormalities in BDUC?
Dino Mehic, Physician Scientist at the Medical University of Vienna, shared a post on LinkedIn about a recent article he and his colleagues co-authored, adding:
“Can global coagulation testing detect abnormalities in BDUC?
Bleeding disorder of unknown cause (BDUC) remains one of the most common diagnoses in patients with a lifelong bleeding tendency, yet routine laboratory testing is normal and objective biomarkers are lacking.
In our study of 464 BDUC patients from the Vienna Bleeding Biobank and 100 healthy controls, we evaluated non-activated whole-blood viscoelastic testing (ROTEM) to determine whether global assays capture hemostatic alterations.
Key findings:
- BDUC patients showed delayed clot formation and reduced maximum lysis resulting in an impaired overall clot formation profile.
- ROTEM parameters discriminated BDUC patients from healthy controls with good performance (ROC-AUC up to 0.81 using machine-learning models).
- Hemoglobin was the strongest determinant of ROTEM variability among clinical and laboratory parameters.
- However, ROTEM parameters did not correlate with bleeding severity, highlighting the complexity of bleeding phenotypes in BDUC.
Take-home: Global viscoelastic testing reveals detectable but modest alterations in clot formation in BDUC, yet these changes do not explain bleeding severity.
The search for robust biomarkers and underlying mechanism in BDUC therefore continues.
