Study on the correlation between NLRP3 inflammasome and IL-1β,TNF-α in acute attacks of gouty arthritis
Objective To analyze the correlation between NOD like receptor pyrin domain containing 3(NLRP3)inflammasome and pro-inflammatory factors interleukin(1L)-1 β and tumor necrosis factor(TNF)-α in the pathogenesis of acute gouty arthritis.Methods From June 2023 to July 2024,76 patients in Wenzhou Hospital of Traditional Chinese Medicine with acute gouty arthritis were selected as case group,and 53 healthy individuals as control group.The mRNA expression levels of NLRP3 inflammasome,apoptosis-associated speck-like protein(ASC),Caspase-1,IL-1β,IL-18,TNF-α were monitored using real-time fluorescence quantitative real-time fluorescence quantitative(PCR),and concentrations of these proteins were determined using enzyme-linked immunosorbent assay(ELISA).Results Age,gender,and other data were similar between both groups(P＞0.05).levels of uric acid,C-reactive protein(CRP),and erythrocyte sedimentation rate(ESR)in case group were higher than those in control group(P＜0.001).Expression of NLRP3,ASC,and Caspase-1 were also higher(P＜0.001).Serum levels of IL-1β,IL-18,and TNF-α were higher in case group(P＜0.05).NLRP3 inflammasome activity correlated positively with IL-1β and TNF-α.Multivariate Logistic regression showed uric acid,CRP,ESR,NLRP3,ASC,Caspase-1,IL-1 β,IL-18,and TNF-α were important factors for acute gouty arthritis attacks(P＜0.05).Conclusion By inhibiting activation of NLRP3 inflammasome or release of downstream inflammatory factors,inflammatory response of gouty arthritis can be effectively reduced,thereby alleviating symptoms and preventing joint damage.
