[Research Advances of Acquired Thrombotic Thrombocytopenic Purpura--Review]

Area of Science:

• Hematology
• Internal Medicine
• Pathology

Background:

• Thrombotic thrombocytopenic purpura (TTP) is a critical thrombotic microangiopathy (TMA).
• Diagnosis traditionally relies on clinical findings like thrombocytopenia and hemolytic anemia.
• Reduced ADAMTS13 activity (<10%) is an established diagnostic criterion for TTP.

Purpose of the Study:

• To review recent advancements in the understanding of TTP.
• To summarize current diagnostic approaches and therapeutic strategies for TTP.
• To highlight novel potential treatments for TTP.

Main Methods:

• Literature review of recent advances in TTP.
• Summary of established diagnostic criteria for TTP.
• Overview of current and emerging therapeutic interventions for TTP.

Main Results:

• Accurate diagnosis and prompt therapy significantly enhance patient survival.
• Current treatments focus on increasing ADAMTS13 activity and inhibiting antibodies via plasma exchange and corticosteroids.
• Novel strategies include recombinant ADAMTS13 and reducing human neutrophil peptide (HNP) release.

Conclusions:

• Early diagnosis and intervention are crucial for improving TTP outcomes.
• Therapeutic plasma exchange and corticosteroids remain cornerstone treatments.
• Emerging therapies targeting ADAMTS13 activity and platelet-vWF interactions show promise for TTP management.
