Stratégie gobale • Traitement curatif

– AB « the faster the better »; contrôle de la source

• Traitement symptomatique – Volume; presseurs; ± I+;

– Assistance respiratoire si besoin

– Assistance rénale si besoin

– Coagulation si besoin…

• Traitement adjuvent: – Anti- / pro- / temps dépendant?

– RCT négatifs… revoir les concepts

Removal of mediatorsCVVH

Payen et al, Crit Care Med 2009 Vol. 37, No. 3

Comparison: conventional therapy vs conventional therapy + CVVH (25ml/kg/h)

Inclusion within 24 hours after meeting the inclusion criteria • Conventional treatment: treatment decided by the physician in charge

• HF treatment: CVVH started within 24 hrs for at least 96 hrs

Primary end point: reduction of number and duration of sepsis-induced organ failure at day 14

Secondary end point:

mortality at day 14;

withdrawal of catecholamines infusion and

length of mechanical ventilation

Primary end point

Evolution of SOFA score in the 2 groups:

SOFA was compared to Day 0. A positive value indicates a maintenance

or a deterioration

Log Rank test: Chi2 : 8.73; p<0.003 HF group

CVVH was associated to longer need for cathecolamines and trend toward higher mortality

Nl

Patients with a slope of log(mHLA-DR) <0.06 (poor recovery of HLA-DR expression) had a

higher risk of secondary infection than the group with slope >0.06.

Sepsis - induced effector cell apoptosis in spleen tissue

Boomer, J. S. et al. JAMA 2011;306:2594-2605

It concerns both innate and adaptive immunity

- Innate: PMNs, Mono-Macro; B Ly; (APC)

- Adaptive: all subsets of Ly pop, except Treg CD25 Foxp3

It concerns both blood and tissue cells

Biomarker guided therapy

To conclude

• Protocolized treatment for acute care positive for outcome avoiding mistakes

• Supportive therapy guidelines are reasonable

– Customized treatment based on comorbidity

• Adjunct therapies: almost all disappeared!!!

• Work on and add some BM for inflammation status

• Immunodepression seems to be a solid concept to be taken potential treatment

Pour conclure:

• Harmoniser les pratiques OUI

• Homogénéiser les prises en charges OUI

• Edicter des Règles plus que des stratégies NON

• Confisquer la connaissance entre quelques mains NON

• Les risques:

– bloquer tout innovation; NON

– bloquer toute publication dans laquelle on ne dira pas avoir suivi la SSC!!! NON
