CCL4 and leprosy: Van Hooij et al. (2016) also identified IP-10 profiles in M. leprae infection and type of leprosy in Bangladesh using UCP-LFA. This cross-sectional study found the correlations of UCP-LFA and ELISA were significant for IL-10, CXCL10, CCL4, and anti-PGL-I-antibodies (p < 0.0001), proving UCP-LFA’s performance was in par with ELISA. Based on AUC, CXCL10 could differentiate MB patients from endemic control or EC (p ≤ 0.05, p ≤ 0.01, p ≤ 0.0001). Concentration of CXCL10 was found higher in HHC with BCG vaccination than HHC without BCG vaccination (p = 0.018).
