Discussion

Review highlights anti-PF4-related thrombosis and thrombocytopenia in various conditions, suggesting critical diagnostic and treatment pathways.

Anti-PF4 antibodies contribute to severe thrombosis, including heparin-induced thrombocytopenia and vaccine-induced immune thrombocytopenia.
Antibodies cause both arterial and venous thrombosis, often with moderate thrombocytopenia observed clinically.
Diagnosis relies on detecting anti-PF4 antibodies and platelet activation in the presence of heparin or PF4.
Treatment options include alternative anticoagulation and high-dose intravenous immunoglobulins for acute cases.

Schönborn et al. (2025) studied this question.
