Summary

The pathophysiology of macrophage activation syndrome has been mainly studied in pediatric genetic primary forms. There is little data in secondary forms related to bacterial sepsis. Because of the seriousness of this entity (43% of deaths in intensive care in the largest cohort published so far by the medical resuscitation team of Rouen University Hospital), it is necessary to better understand the physiopathological mechanisms to be able to propose a suitable therapy. For now, the management of this syndrome is far from consensual. Some authors advocate a single etiological treatment, while others suggest the need for intensive management of anti-inflammatory and immunosuppressive type. The fragility of resuscitation patients does not allow intensive immunosuppressive therapies as proposed by some authors. In the era of immunotherapy, the precise knowledge of physiopathological data would make it possible to propose a targeted therapy with little risk of adverse effects. Recent work has indeed shown excellent tolerance of immunotherapy during sepsis and could be applied eventually in patients with macrophage activation syndrome.

Conditions

• Macrophage Activation Syndrome

Interventions

Type	Name	Description
BIOLOGICAL	Blood samples	There are 3 specific blood sampling times for each patient, on D1, D2 and D5 (D1 being the day of inclusion): cytokine samples (IL-1β, IL-6, IL-10, TNF-α, IFN-gamma) on 5ml dry tube. On D1, a 2.5ml PAXgene tube will also be taken for each patient.
