• Lower levels of mHLA-DR (5913–7927 Ab/c vs 25,477–34,295 Ab/c; p<0.001) and lower CD4+ T cells (332–1186 cells/μL vs 895–2187 cells/μL; p<0.01) for patients with septic shock vs healthy controls• Lower levels of mHLA-DR for those with secondary infection vs those without secondary infection (Days 1–2 mHLA-DR, 4146 Ab/c vs 8704 Ab/c; p=0.28; Days 3–5, 4398 Ab/c vs 8474 Ab/c; p=0.022) (91). This evidence concerns the gene CD4 and infection.
