Necrosis Factor

Background Many genes have been implicated in the pathogenesis of systemic lupus erythematosus (SLE). Tumor necrosis factor (TNF) is a potent cytokine stimulator acting through 2 cell surface receptors (TNFR I and II). TNFRII gene which controls expression of these receptors has been linked to SLE susceptibility through promoting apoptosis. Also; Protein tyrosine phosphatase non receptor 22 (PTPN22) gene enhances intrinsic phosphatase activity of T lymphocytes leading to their dysregulation and stimulates autoimmune process of lupus and its rs2476601 has been linked to susceptibility to thyroiditis in SLE patients in few studies. Objectives (i) to investigate the correlation between 2 SNPs of TNFR II and PTPN22 genes and SLE susceptibility in a cohort of Egyptian children compared to controls (ii) and to investigate their possible association with different clinical presentations of the disease in children. Subjects and methods Typing of TNFR II rs1061622 and PTPN22 rs2476601 SNPs were done using polymerase chain reaction-restriction fragment length polymorphism for 74 children with SLE and 100 matched healthy controls. Results Children with SLE had more frequent G allele and GG genotype of TNFR II rs1061622 ( p < 0.001) and more T allele and TT genotype of PTPN22 rs2476601 ( p = 0.012 and <0.001, respectively) compared to controls. Only 6 patients (8%) had thyroiditis (hypothyroidism) with T allele and TT genotype of PTPN22 1858 T more prevalent in those patients versus those without thyroiditis ( p ≤ 0.001). Apart from, thyroiditis, no significant association was found between genotypes and alleles frequencies of the 2 studied SNPs and other clinical manifestations of the disease. Conclusion The G allele and GG genotype of TNFR II rs1061622 and T allele and TT genotype of PTPN22 rs2476601 genes polymorphism can be considered as risk factors for the development of SLE. The presence of the T allele of PTPN22 rs2476601 may increase the risk of concomitant thyroiditis in Egyptian children with SLE but further studies are required to confirm this finding as thyroiditis was reported only in few cases in this study.

Objectives To analyze the association of adipokines and tumor necrosis factor α (TNFα) and its receptors with characteristics of systemic lupus erythematosus (SLE) and to investigate the correlation between adipokines and the TNF system. Methods One hundred and thirty-six SLE women, aged ≥18 years old, were assessed. TNFα, soluble TNFα receptors 1 (sTNFR1) and 2 (sTNFR2) and adipokines were analyzed by ELISA kits. Results The median (IQR) of age was 41.5 (33.0–49.7) years old and of disease duration 11.3 (7.8–15.8) years. The median (IQR) of disease activity was 0 (0–4) and of damage index was 2 (1–3). Higher levels of sTNFR1 and sTNFR2 were associated with nephritis ( p < 0.001 for both), and sTNFR1 ( p = 0.025) and TNFα ( p = 0.014) were positively associated with arthritis. Higher sTNFR1 levels were found in participants that were not using antimalarial drugs ( p = 0.04). Independent correlation was found between sTNFR1 (β = 0.253; p = 0.003) and sTNFR2 (β = 0.297; p < 0.001) levels and disease activity and damage index (sTNFR1: β = 0.367; p < 0.001; sTNFR2: β = 0.335; p < 0.001). Higher adiponectin levels were independently associated with nephritis ( p = 0.009) and antimalarial drugs use ( p = 0.015). There was a positive correlation between leptin and sTNFR2 levels ( p = 0.002) and between resistin levels and sTNFR1 ( p < 0.001) and sTNFR2 ( p < 0.001). Conclusion The correlation between adipokines and TNF system allows a better understanding of the role of adipokines in the inflammatory response in SLE patients.

Objective.To detect autoantibodies to tumor necrosis factor (TNF) in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), and to determine their clinical correlates.Methods.Ninety-two patients with RA and 62 with SLE were studied. Sera were examined for autoantibodies to TNF by enzyme linked immunoassay. Levels of these autoantibodies were analyzed in respect to markers of inflammation such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and joint erosions, as well as other clinical, laboratory, and therapeutic aspects of RA and SLE.Results.Anti-TNF levels were higher in those RA patients without erosions, but did not correlate with ESR or CRP.Conclusion.These observations suggest that autoantibody anti-TNF may be part of the innate immune system and may contribute to decreased inflammation in patients with RA.
