1/ What are PF4 Abs?

Abs against Platelet Factor 4 (PF4) can trigger immune responses, leading to dangerous clotting disorders. They play a central role in conditions like Heparin-Induced Thrombocytopenia (HIT) & Vaccine-Induced Thrombotic Thrombocytopenia (VITT). A short 🧵... 2/ Types of PF4 Abs

PF4 Abs can be classified into three types:
🟢Type 1: Non-pathogenic (no platelet activation)
🟠Type 2: Heparin-dependent, platelet-activating (HIT)
🔴Type 3: Heparin-independent, platelet-activating (autoimmune HIT, VITT)

The story of the anti-pernicious-anaemia factor started in 1938 and ended in 1948 with the isolation of a red crystalline compound now called B12.

1/ Did you get you right? A short 🧵on leucocytosis and leukostasis 2/ You can't solely rely on morphology for a diagnosis, but there is a good chance you are dealing with some sort of high-grade haematological malignancy. Monoblastic leukaemia topped the differentials and was the final diagnosis.

He’s Fredrick W Mott, an English 🏴󠁧󠁢󠁥󠁮󠁧󠁿surgeon who identified cells with multiple spherical inclusions packed in their cytoplasm in the brains of monkeys with trypanosomiasis. 2/ In the early 1900s, he identified them as plasma cells in inflammation and called them morular cells (Latin morus=mulberry).
