['Adjunctive immunoadjuvant therapies are now proposed in the treatment of septic patients that develop immune dysfunctions. However, a prerequisite is to identify patients at high risk of death that would benefit from such therapy. Knowing that rhIL-7 is a putative candidate for septic shock treatment, we evaluated the association between increased plasmatic level of soluble CD127 (sCD127, IL-7 receptor alpha chain) and mortality after septic shock.', 'sCD127 plasmatic level was measured in 70 septic shock patients sampled at day\xa01-2 (D1) and day\xa03-4 (D3) after the onset of shock and 41 healthy volunteers.', 'Compared with survivors, non-survivors presented with significantly higher sCD127 concentrations at D1 and D3 (p\xa0<\xa00.001 and p\xa0=\xa00.002). At D1, the area under the receiver operating characteristic curve for sCD127 level association with mortality was 0.846 (p\xa0<\xa00.0001). Kaplan-Meier survival curves illustrated that mortality was significantly different after stratification based on D1 sCD127 level (log rank test, hazard ratio 9.10, p\xa0<\xa00.0001). This association was preserved in multivariate logistic regression analysis including clinical confounders (age, SAPS\xa0II and SOFA scores, odds ratio 12.71, p\xa0=\xa00.003). Importantly, patient stratification on both D1 sCD127 value and SAPS\xa0II score improved this predictive capacity (log rank test, p\xa0=\xa00.0001).'] Is elevated plasmatic level of soluble IL-7 receptor associated with increased mortality in septic shock patients?
