ANCA is a powerful diagnostic tool—but only when used in the right clinical context.
A positive ANCA does not diagnose ANCA-associated vasculitis, and a negative ANCA does not exclude it.
This infographic summarizes when to order ANCA, how to interpret PR3-ANCA and MPO-ANCA, common diagnostic pitfalls, and why clinical phenotype always comes before laboratory results.
Interpret the patient—not just the antibody.

🌟IgG4RD: Lessons from the first 20 years🌟by Prof John Stone
⭐️Lesson 1- IgG4RD is a variable vessel vasculitis
✨Can cause small vessel vasculitis of the skin
✨One of few vasculitis causing coronary arteritis in adults
⭐️Lesson 2- IgG4RD is more common and severe in males
✨M/F- 2.2 to 1
✨Males diagnosed 5 years older
⭐️Lesson 3- IgG4RD has no diagnostic histopathology
✨Always remember (do NOT occur in IgG4RD)
⭐️Lesson 4-Serum IgG4 levels is a good biomarker
✨Reflects disease activity
✨Serum IgG4 levels >5 ULN [PPV-75% (69-81%)]
⭐️Lesson 5- Rising IgG4 levels should not be ignored
⭐️Lesson 6- Pancreas in IgG4RD is the analogue of the kidney in AAV
⭐️Lesson 7- B cell therapy is highly effective in IgG4RD
❤️❤️Only person who can make diagnosis of IgG4RD is the CLINICIAN❤️❤️
✨Future therapy- Obexelimab (Bifunctional antibody)✨

Frequency of ANCA positivity in different conditions. Atypical ANCAs w/negative PR3 or MPO can be found in a range of nonvasculitic conditions (inflammatory bowel disease, autoimmune disease, malignancy & chronic infection)

Good morning, dear ladies and gentlemen! Today, #Scientissimum would like to present an #anatomy case focusing on the #knee and its joints. The knee connects the thigh to the leg and comprises two joints: one between the femur and tibia known as the tibiofemoral joint, and another between the femur and patella referred to as the patellofemoral joint. Serving as the largest joint in the human body, the knee functions as a modified hinge joint, allowing for flexion and extension, along with subtle internal and external rotation movements.🦵🏼

¡Buenos días, queridos damas y caballeros! Hoy nos gustaría presentar un caso de #anatomía centrándonos en la #rodilla y sus articulaciones. La rodilla conecta el muslo con la pierna y comprende dos articulaciones: una entre el fémur y la tibia conocida como articulación tibiofemoral, y otra entre el fémur y la rótula denominada articulación femororrotuliana. La rodilla, la articulación más grande del cuerpo humano, funciona como una articulación de bisagra modificada, lo que permite la flexión y extensión, junto con sutiles movimientos de rotación interna y externa.👨🏽⚕️

Bom dia, queridos senhoras e senhores! Hoje gostaríamos de apresentar um caso de anatomia com foco no #joelho e suas articulações. O joelho conecta a coxa à perna e compreende duas articulações: uma entre o fêmur e a tíbia, conhecida como articulação tibiofemoral, e outra entre o fêmur e a patela, conhecida como articulação patelofemoral. Servindo como a maior articulação do corpo humano, o joelho funciona como uma articulação modificada, permitindo flexão e extensão, juntamente com movimentos sutis de rotação interna e externa.🏥
