🌍 Hoy, 1 de febrero, conmemoramos el Día Europeo de la enfermedad de von Willebrand (#EVW) el trastorno hemorrágico hereditario más frecuente. 🩸Hematomas recurrentes, sangrados nasales o menstruaciones muy intensas pueden ser señales de alerta. 🔬Desde la #SETH impulsamos el diagnóstico precoz, el tratamiento y la calidad de vida de las personas con EVW, a través de la formación, la investigación y la colaboración con otras entidades. 👉Más información sobre la EVW: seth.es/que-es-la-enfe… #DíaEuropeoEVW #coagulopatías #VonWillebrand #EVW #hemostasia #SETHemostasia #hemostasia @isth

🩸 Thrombocytopenia in CTD 🟢 ITP → isolated ↓PLT, no hemolysis 🔴 TMA → ↓PLT + MAHA = TMA until proven otherwise 🟠 MAS → fever + 🚀 ferritin + cytopenias 🔵 Drug-induced → recent drug, abrupt drop, rapid recovery 🚨 Red flags matter. Pattern recognition saves lives.

🩸 Anticoagulation in Hematologic Malignancies — Full Fellow Pearls 🔥 Why VTE risk is high 🧬 Malignancy: ↑ TF, ↑ FVIII/vWF, cytokines, endothelial injury 💉 Therapy: Asparaginase, steroids, TKIs, IMiDs, CAR-T, chemo 👤 Patient: Age, comorbidities, ECOG ≥2, CVCs, immobility ⸻ 🧨 Incidence by disease 🅰️ ALL: up to 30% 🅰️ AML: 11–16% 🧠 Primary CNS lymphoma: highest risk (up to 60%) 🔥 Aggressive lymphomas: 8–12% 🧱 Multiple Myeloma: 10–26% (IMiD-related) ⸻ 🧬 Acute Leukemias 🟣 ALL + Asparaginase = highest thrombosis driver 🟣 Prefer LMWH > DOACs 🧬 Antithrombin deficiency → key mechanism 🩸 Prophylaxis: only if Plt ≥50k + risk factors ⚠️ APL: DIC dominates → anticoagulation not routine ⸻ 🧬 Chronic Leukemias (CML/CLL) ⚡ BTK inhibitors (ibrutinib) → AF + platelet dysfunction ❤️ AF management: Prefer DOACs, avoid warfarin 🔄 Consider switching ibrutinib → acalabrutinib if bleeding risk ↑ ⸻ 🔥 Lymphomas ⛰️ High-risk settings: bulky disease, ECOG ≥2, mediastinal mass 💉 Checkpoint inhibitors ↑ VTE risk 🧮 ThroLy score = limited performance ⸻ 💥 Multiple Myeloma 🎯 IMPEDE-VTE = standard 🎯 PRISM = emerging strong model 🛡️ Prophylaxis: • Low risk → aspirin • High risk → LMWH or DOACs 🕒 Continue ≥4–6 months; extend if IMiDs continue ⸻ 🧬 HSCT 🔸 VTE 3–8% (mostly catheter-related) 🔸 No prophylaxis during aplasia 🔸 Chronic GVHD → 22% thrombosis at 5 years 🔸 Start AC after Plt >50k ⸻ ⚡ CAR-T 🔥 Cytokines + endothelial injury 📊 VTE = 2.4% per patient-month (first 6 months) 🛡️ No routine prophylaxis ⸻ 💊 Anticoagulant Choice 🟣 DOACs 👍 Easy use ⚠️ Avoid in GI lymphoma ⚠️ CYP3A4/P-gp interactions (BTKi, PI3Ki, azoles, HDACi) 🔵 LMWH ✔️ Best for unstable platelets, leukemia, HSCT, CAR-T ⚠️ Avoid CrCl <30 🔸 Fondaparinux ✔️ HIT-safe ⚠️ Long half-life ⚪ UFH ✔️ Best for high bleeding risk ✔️ Fully reversible 🟡 Warfarin ⚠️ Hard to control ✔️ Required in mechanical valves ⸻ 🩸 Thrombocytopenia + AC Plt ≥50k → full-dose Plt 25–49k → reduce-dose LMWH/UFH Plt <25k → hold AC 📌 For high-risk clot (PE/proximal DVT): transfuse to ≥40–50k 📌 Restart full dose when Plt ≥50k ⸻ 🧠 CNS Disease ✔️ Aim Plt ≥50k–80k ✔️ DOACs show lower ICH vs LMWH ⸻ 📌 Catheter-Related Thrombosis 🚫 No prophylaxis ✔️ Smallest catheter possible ✔️ Treat ≥3 months ⸻ 🔥 Superficial Thrombosis Treat if near deep system or within 3 cm of saphenofemoral junction ⸻ ⚠️ Drug Interactions 📌 BTKi → ↑ bleeding + AF 📌 PI3Ki → ↑ DOAC levels 📌 BCL-2i (venetoclax) → thrombocytopenia 📌 HDACi → ↑ DOAC levels 📌 TKIs → affect warfarin metabolism ⸻ 🔭 Ongoing Trials 🧪 HAT – risk of bleeding/clot in heme cancers 🧪 CICERO – DOACs + acalabrutinib safety 🧪 START – AC in thrombocytopenia 🧪 Apixaban Secondary Prevention phase 3 ⸻ 🧠 Fellow Pearls 🟣 Always check Plt count before AC choice 🟣 ALL on asparaginase → LMWH + AT monitoring 🟣 MM on IMiDs → mandatory risk scoring 🟣 BTKi-AF → DOAC + consider switch to acalabrutinib 🟣 HSCT → hold during aplasia 🟣 Avoid DOACs with mucositis/vomiting/malabsorption ⸻ 📚 Reference Alyamany R, Houghton DE.

@DrAkhilX Days are not far where irrespective of DNA/HbeAg status, all HbsAg will be started on therapy. Dr Sarin has spoken about this in various talks. If I remember correctly, WHO has started the same treat all approach in Africa
