Abstract:
Objective We compared peripheral blood nucleotide-binding oligomerization domain-leucinerich repeats containing pyrin domain 3 (NLRP3),cysteinyl aspartate specific proteinase-1 (Caspase-1),interleukin-1β (IL-1β) and IL-18 between acute and chronic brucellosis patients before treatment and revealed their immune characteristics,to find targets for immune intervention of brucellosis.Methods From March to April 2016,42 acute and 42 chronic brucellosis patients were selected from Ulanqab Center for Endemic Disease Prevention and Control as the research subjects,and 20 local healthy persons were selected as healthy control.Brucellosis were diagnosed according to the "Diagnostic Criteria of Brucellosis".Enzyme-linked immunesorbent assay (ELISA) method was used to determine serum levels of NLRP3,Caspase-1,IL-1β and IL-18.Results The expression levels of NLRP3,Caspase-1,IL-1β and IL-18 [(1 264.40 ± 424.74),(1 350.67 ± 468.93),(192.96 ± 61.52),(162.74 ±54.23),(172.44 ± 60.56),(120.10 ± 61.52),(47.23 ± 13.79),(46.68 ± 14.72),(27.71-± 8.71),(202.23 ± 65.24),(169.19 ± 54.33),(108.62 ± 41.39) ng/L] were compared in acute,chronic and control groups,the differences were statistically significant (F =61.96,6.26,16.68,18.31,P ＜ 0.01).Compared to control group,the levels of NLRP3,Caspase-1,IL-1β and IL-18 in acute and chronic groups were significantly increased (P ＜ 0.05);compared to chronic group,the levels of IL-18 in acute group were significantly increased (P ＜ 0.05),and NLRP3,Caspase-1 and IL-1 β levels were not statistically different (P ＞ 0.05).Conclusions This study has showed that the expression of NLRP3 inflammasome in innate immunity is not significantly different between acute brucellosis and chronic brucellosis.The difference of IL-18 levels between acute and chronic brucellosis may affect their immune response.
