Circulating CXCL10 in leprosy patients and healthy controls. Each point represents one sample from a different individual. The groups were healthy controls, borderline tuberculoid without reaction (BT), borderline lepromatous without reaction (BL), polar lepromatous without reaction (LL), BT with reaction (BT plus RR), BL with reaction (BL plus RR), and LL patients with T2R (erythema nodosum leprosum). For patients with reaction (BT plus RR, BL plus RR, and T2R), the sample was taken at the time of reaction, prior to treatment. For LL, n = 6; for all other groups, n = 10. The horizontal lines indicate median values. The median level of CXCL10 in LL patients with type 2 reaction was not significantly elevated (P = 0.9).
