Objective To compare the distribution of CD4+ Th17 and CD25+ FOXP3 T regulatory cell (Treg) between  type I reversal reaction (RR) and type II reversal reaction i.e. erythema nodosum leprosum (ENL) patient groups.


Methods A total of 50 samples, consisted of 27 samples of reversal reaction (RR) and 23 samples of ENL, were collected. Observation of CD4+ RORg-T Th17 and CD25+ FOXP3 Treg were conducted with immunohistochemistry staining technique using anti FOX-P3 and anti RORg-T. Expression of CD4+ ROR-g Th17 and CD25+ FOXP3 Treg in percentage were analyzed using T-test.


Results There is a significant difference in mean CD4+ ROR-g Th17 and IL17 cell distribution for RR patient group (14.96% and 10.72%) compared with ENL (9.12% and 4.28%). No significant difference were found between mean CD25+ FOXP3 Treg and TGF-β cell distribution in RR patient group (6.12% and 5.44%) compared with ENL group (6.16% and 5.96%).


Conclusion There is a significant increment od CD+RORg-T Th17 and IL17 in RR patients group compared with ENL patients group. however, the distribution of CD25+ FOXP3+ Treg and TGF beta in RR has no significant difference compared with ENL.
