Complement Activation Is Associated With Mortality in Patients With Necrotizing Soft-Tissue Infections-A Prospective Observational Study.

ABSTRACT: Aim: We assessed whether different complement factors and complement activation products were associated with poor outcome in patients with necrotizing soft-tissue infection (NSTI). Methods: We conducted a prospective, observational study in an intensive care unit where treatment of NSTI is centralized at a national level. In 135 NSTI patients and 65 control patients, admission levels of MASP-1, MASP-2, MASP-3, C4, C3, complement activation products C4c, C3bc, and terminal complement complex (TCC) were assessed. Results: The 90-day mortality was 23%. In a Cox regression model adjusted for sex, and SAPS II, a higher than median MASP-1 (HR 0.378, CI 95% [0.164-0.872], p = 0.0226) and C4 (HR 0.162, 95% CI [0.060-0.438], p = 0.0003), C4c/C4 ratio (HR 2.290 95
