Higher interleukin-33 levels in aggressive periodontitis cases.

ABSTRACT: Context:Interleukin-33 (IL-33) is a novel alarmin that warns immune cells of tissue destruction in injury or infection. Aims:This study is aimed at analyzing and correlating the concentration of IL-33 in the gingival crevicular fluid (GCF) and plasma of healthy subjects and chronic and aggressive periodontitis patients with intronic variant single nucleotide polymorphisms (SNPs), rs1157505 (C/G) and rs7044343 (C/T) in the IL-33 gene. Settings and Design:This is a cross-sectional, biochemical, genetic study. Materials and Methods:Ninety subjects were divided into Group H: subjects with healthy periodontium, Group CP: chronic periodontitis patients, and Group GAgP: generalized aggressive periodontitis patients, based on clinical parameters of periodontal inflammation. IL-33 concentration in GCF, as well as plasma, was quantified using enzyme-linked immunosorbent assay. The SNPs rs1157505 and rs7044343 were analyzed using polymerase chain reaction-restriction fragment length polymorphism. Results:A significant difference was found in IL-33 concentration in GCF and plasma between the three groups. GG genotype of IL-33 SNP rs1157505 was associated with the highest GCF and plasma IL-33 concentration and was significantly more in GAgP than healthy or CP groups. IL-33 SNP rs7044343 did not show any such association. All GAgP patients had the highest GCF and plasma concentration of IL-33. Conclusions:IL-33 may be a potential inflammatory marker of periodontitis. GG genotype of SNP rs1157505 may be associated with GAgP.

Project description:Abstract Background Previous studies reported that patients with asthma showed higher levels of interleukin (IL)‐33 in peripheral blood, compared to healthy control (HCs). However, we also noticed that there were no significant differences of IL‐33 levels between controls and asthma patients in a recent study. We aim to conduct this meta‐analysis and evaluate the feasibility of IL‐33 in peripheral blood that may act as a promising biomarker in asthma. Methods Articles published before December 2022 were searched in these databases (PubMed, Web of Science, EMBASE, and Google Scholar). We used STATA 12.0 software to compute the results. Results The study showed that asthmatics showed higher IL‐33 level in serum and plasma, compared to HCs (serum: standard mean difference [SMD] 2.06, 95% confidence interval [CI] 1.12−3.00, I2 = 98.4%, p < .001; plasma: SMD 3.67, 95% CI 2.32−5.03, I2 = 86.0%, p < .001). Subgroup analysis indicated that asthma adults showed higher IL‐33 level in serum, compared to HCs, whereas no significant difference in IL‐33 level in serum was showed between asthma children and HCs (adults: SMD 2.17, 95% CI 1.09−3.25; children: SMD 1.81, 95% CI −0.11 to 3.74). The study indicated that moderate and severe asthmatics showed higher IL‐33 level in serum, compared to mild asthmatics (SMD 0.78, 95% CI 0.41−1.16, I2 = 66.2%, p = .011). Conclusions In conclusion, the main findings of present meta‐analysis suggested that there was a significant correlation between IL‐33 levels and the severity of asthma. Therefore, IL‐33 levels of either serum or plasma may be regarded as a useful biomarker of asthma or the degree of disease. In conclusion, the main findings of present meta‐analysis suggested that there was significant correlation between interleukin (IL)‐33 levels and the severity of asthma. Therefore, the IL‐33 levels of either serum or plasma may be regarded as a useful biomarker of asthma or the degree of disease. However, we can not ignore the influences of ethnic and age factors on the IL‐33 levels. It is encouraged that data from multi‐center, well‐designed and large sample size studies should be conducted for validating the clinical value of IL‐33 on asthma.
