IL6 and parasitic infectious disease: Immune molecules such as interleukin-6 (IL-6), soluble triggering receptor expressed on myeloid (sTREM), eotaxin-1, fatty acid-binding protein (FABP), soluble CD23 (sCD23), and lipopolysaccharide (LPS) have been evaluated in previous studies as potential diagnostic markers for parasitic infections and sepsis (10–13).
