New study probes blood clot secrets in sepsis patients on kidney machines
NCT ID NCT06440317
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how a special filter (OXIRIS membrane) used for kidney dialysis affects blood clotting and immune cells in intensive care patients with septic shock. Researchers will measure markers of clotting and immune activation before and after using the filter. The goal is to better understand the body's response during severe infection, not to provide a direct treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients aged 18 years and older * Admitted to the intensive care unit with septic shock, defined as an increase in the Sequential Organ Failure Assessment (SOFA) score of at least 2 points due to infection, requiring vasopressor drugs to maintain a mean arterial pressure (MAP) ≥ 65 mmHg, and a lactate level \> 2 mmol/L (18 mg/dL) despite adequate fluid resuscitation * Requiring renal replacement therapy according to consensus indications: * KDIGO stage 3 acute kidney injury with oliguria or anuria persisting for more than 72 hours * Urea \> 40 mmol/L * Plasma potassium \> 5.5 mmol/L despite medical treatment * pH \< 7.15 (pure metabolic acidosis with PaCO2 \< 30 mmHg or mixed acidosis with PaCO2 \> 50 mmHg without the possibility of improving alveolar ventilation) * Acute pulmonary edema secondary to hydrosaline overload resulting in severe hypoxemia (oxygen flow \> 5 L/min or FiO2 \> 50% during mechanical ventilation to maintain SaO2 \> 95%) despite diuretic therapy * Receiving continuous renal replacement therapy with a high-adsorption membrane (oXiris membrane) or a conventional membrane (HF1400 membrane) Exclusion Criteria: * Known history of constitutional thrombopathy (Bernard Soulier disease, Glanzmann thrombasthenia, Gray's syndrome or dense granule disease) * Myelodysplastic or myeloproliferative syndrome * Autoimmune thrombocytopenic purpura * Acute leukemia * Hemorrhagic shock * Platelet transfusion within 7 days prior to inclusion * Antiplatelet therapy with clopidogrel or ticagrelor within 5 days prior to inclusion, prasugrel or dipyridamole within 7 days prior to inclusion * Active HIV infection or hepatitis B or C * Pregnant woman * Not affiliated to a social security system or not benefiting from such a system
