  • Title: Anti-inflammatory response after infusion of p55 soluble tumor necrosis factor receptor fusion protein for severe sepsis.
    Author: Butty VL, Roux-Lombard P, Garbino J, Dayer JM, Ricou B, Geneva Sepsis Network.

    Abstract:
    OBJECTIVES: To investigate the effects of Lenercept , a recombinant soluble TNF receptor p55 fused to an immunoglobulin heavy chain IgG1, on the balance of pro- and anti-inflammatory mediators in sepsis. DESIGN: Post hoc analysis of a subgroup of patients enrolled in a multicenter phase III, prospective, double-blind, placebo-controlled, randomized study of Lenercept in severe sepsis. SETTING: Surgical and medical intensive care units, and postoperative recovery room of a tertiary care teaching hospital. PATIENTS: A total of 57 patients were enrolled in the multicenter study in our center. INTERVENTION: Septic patients were randomly assigned to receive either Lenercept 0.125 mg/kg or placebo. The patients were followed for up to 28 days after randomization. MEASUREMENTS AND MAIN RESULTS: Circulating levels of TNF-alpha, IL-6, TNFsR75 and IL-1Ra were measured before and after treatment. The two groups were comparable with regard to age, gender and diagnosis distribution. The total level of TNF-alpha increased significantly in treated patients, compared to patients receiving placebo. The levels of the other inflammatory mediators did not differ between the two groups CONCLUSIONS: Lenercept -treated patients experienced a protracted TNF-alpha half-life, leading to higher total TNF-alpha levels throughout the study. However, the treatment had no effects on anti-inflammatory mediators. Therefore, peripheral inflammatory processes might not have been significantly modified by the treatment. This might account for the lack of efficacy this treatment in septic patients
