IL17A and leprosy: The results of the IL-17 level in this study are similar to a previous study by Sadhu et al. which proved that Th17 was more significantly found in BT/TT type leprosy patients compared to BL/LL (p < 0.05), where the levels of IL-17 are higher in patients with PB leprosy than multibacillary (MB) leprosy [12].
