What an inspiring #ISTH2025!
It was wonderful to host the global #thrombosis & #hemostasis community in DC.
From the latest science & innovations to networking & building new collabs - it had it all!
Look out for recordings & other post- @isth.org congress updates.
Goodbye & see you @ #ISTH2026!

Now my favourite topic presented eloquently by prof Marc Rodger.

Answering all the questions needed for providing well-informed information to your patients.

Put the #LMWH needles away in patients with placenta-mediated complications in inherited #thrombophilia!

It took 7 years to recruit 51 patients for the IMPACT single-arm study on certiluzomab on top of LMWH-aspirin shows adverse outcome in 20% which is lower than non-contemporary controls.

More on pregnancy and #APS, now from obstetric perspective.

Only 1% of recurrent miscarriage patients had APS antibodies, similar to controls.

Implementation matters!
A guideline-driven VTE prevention program (Vermont Model) led to ~60% of high-risk cancer patients receiving prophylactic anticoagulation—resulting in a 60% reduction in VTE and 56% reduction in death. #ISTH2025 #VTEprevention 🩸

Why do we have so little data on pregnancy and thrombotic outcomes in #APS??

Well-illustrated by State-of-the-Art lecture by dr Karen Breen.

We MUST do better!

📣 ARIVA Trial at #ISTH2025:

🧪 First RCT on antithrombotic therapy post-venous stenting for PTS
🔵 6-month primary patency rate was higher than expected
💊 No added benefit of aspirin + rivaroxaban vs. rivaroxaban alone

Meta-analysis on GLP-1RA (vs. placebo) and VTE:
🔹 PE rates significantly lower 📉
🔹 VTE rates lower but not statistically significant
🔹 No difference in DVT
🔹 Study design matters: RCTs vs. observational data
Accepted for publication in JTH!

It’s really worth stopping by our @isth.org booth and get inspired for next year’s meeting in….. Paris!

What started as strong Mendelian observations, has now evolved to a strongly polygenenic etiology of #VTE. Inside and outside the coagulation cascade.

Tips for asking ?s as moderator #ISTH2025

Clinical talk: what future directions do you see this work taking?

Basic science: how do you envision this translating to the clinic?

Next level pro tip: contact author beforehand to see what they didn’t have time to present that they’d like you to ask

Adjust-DVT study. Only 5% of patients with suspected #DVT had an age-adjusted d-dimer that omits the need for compression ultrasound.

I don’t think it is worth it. What do you think?

This is why diagnosing, treating and investigating #APS is so complicated.
Massive differences in classification between Sydney 2006 and ACR/EULAR 2023. Only 40% of patients fulfilled the new criteria.
What are the implications for future research?

The effects of andexanet on enoxaparin are in line with effects on oral factorXa inhibitors.

State-of-the-Art talk bij de Luuk Scheres

Despite hormone use being the most prevalent and important risk factor for #VTE in women <50, there is huge underrepresentation of risk models and funding.

Food for thought and action 💪🏼

There is still taboo about discussing menstruation 🩸

There are differences between assessment of abnormal uterine bleeding between professional societies.
This is important to realisme and underscores the need to collaborate multidisciplinary.

Good morning everyone! Another exciting day ahead #ISTH2025.

Thirty years ago I visited my first @isth.org Congress.
📣 This morning, I can switch sessions to see two of my former PhD students shine in State-of-the-Art sessions.
We take good care of the next generation @isth.org!

Interesting data on influence of race from the RIETE registry. After correction for treatment etc, these differences did not show in multi-variate analysis.

VTE isn’t “over” at discharge.
Many patients face lasting symptoms & distress.

🗣️ PROMs help reveal what matters, if we use them right.
✅ Ask
✅ Act
✅ Guide care

Structured models like Attend-PE show the way.
