How I treat quantitative fibrinogen disorders

Area of Science:

• Hematology
• Genetics
• Clinical Medicine

Background:

• Quantitative fibrinogen disorders (afibrinogenemia, hypofibrinogenemia) are monogenic conditions characterized by absent or reduced fibrinogen.
• Severity correlates with fibrinogen levels, impacting bleeding risk from mild to life-threatening.
• These disorders present unique challenges in managing bleeding, thrombosis, surgery, and pregnancy.

Purpose of the Study:

• To present clinical scenarios illustrating common challenges in managing quantitative fibrinogen disorders.
• To propose evidence-based strategies for addressing bleeding, thrombosis, surgical interventions, and pregnancy in affected individuals.

Main Methods:

• Diagnosis relies on measuring fibrinogen activity and antigen levels.
• Case-based approach presenting 4 distinct clinical scenarios.
• Review of current literature and clinical guidelines for management strategies.

Main Results:

• Afibrinogenemia typically involves severe bleeding, while hypofibrinogenemia ranges from asymptomatic to mild bleeding.
• A prothrombotic tendency exists, potentially worsened by fibrinogen supplementation.
• Management requires tailored fibrinogen replacement and thromboprophylaxis, especially during surgery and pregnancy.

Conclusions:

• Effective management of quantitative fibrinogen disorders necessitates a comprehensive approach addressing bleeding, thrombosis, and specific life events.
• Clinical scenarios highlight the complexity and need for individualized treatment strategies.
• Further research may refine optimal therapeutic protocols for these rare conditions.
