Plasma Cytokines and Chemokines in Zambian Children With Measles: Innate Responses and Association With HIV-1 Coinfection and In-Hospital Mortality.

To identify immune factors present during the acute rash phase of measles and associations with outcome and human immunodeficiency virus type 1 (HIV-1) coinfection, we measured the plasma levels of 22 cytokines and chemokines in Zambian children hospitalized with measles (n = 148) and control children (n = 44). Children with measles had higher levels of innate cytokines tumor necrosis factor (TNF) α, interleukin 1β (IL-1β), interleukin 18, and interleukin 6; chemokines CCL2, CCL4, CCL11, CCL22, CXCL8, and CXCL10; and T-cell cytokines interferon γ, and interleukin 2, 10, and 17. Children who died in the hospital had higher levels of TNF-α, IL-1β, interleukin 12p70; CCL2, CCL4, CCL13, CCL17, CXCL8, CXCL10; and interleukin 2 and interferon γ than children who survived, and lower levels of interleukin 4. Children coinfected with HIV-1 had higher levels of TNF-α and IL-1β than HIV-uninfected children with measles, and lower levels of interleukin 4 and 5. Therefore, acute measles was characterized by activation of macrophages and T cells producing type 1, but not type 2, cytokines, which was more pronounced in fatal disease.
