Rheumatoid Arthritis is a widespread disease causing varying degrees of disability. It is characterised by flares and remissions and since ancient times, every culture has tried to get the better of it. Even now, research is aimed at finding novel serum biomarkers as surrogates for disease activity and newer targets to sharpen therapy. One such target is IL-6.It mediates neutrophil migration, osteoclast maturation and pannus formation through vascular endothelial growth factor (VEGF) stimulation causing synovitis and joint destruction.IL-6 leads to various systemic manifestations like hepcidin production causing anemia hypothalamo-pituitary–adrenal (HPA) axis activation causing fatigue and mood changes and osteoclast activation causes osteoporosis while increase in acute phase reactants (ESR and CRP). The literature we reviewed and our research, enrolling 40 patients of RA as well describes the role of IL-6 in pathogenesis and various manifestations of RA including articular, extra-articular and other comorbid states. It supports that Serum IL-6 levels correlate with disease activity (DAS-28ESR and BRAF-MDQ) and that IL-6 remains a viable target for drug therapy.

Endothelial Growth Factor

Recent experimental and clinical studies have placed new emphasis on the role of angiogenesis in chronic inflammatory disease. Vascular endothelial growth factor (VEGF) and its receptors are the best characterized system in the regulation of rheumatoid arthritis (RA) by angiogenesis. Furthermore, in addition to its angiogenic role, VEGF can act as a direct proinflammatory mediator during the pathogenesis of RA, and protect rheumatoid synoviocytes from apoptosis, which contributes to synovial hyperplasia. Therefore, the developments of synovial inflammation, hyperplasia, and angiogenesis in the joints of RA patients seem to be regulated by a common cue, namely, VEGF. Agents that target VEGF, such as anti-VEGF antibody and aptamer, have yielded promising clinical data in patients with cancer or macular degeneration, and in RA patients, pharmacologic modulations targeting VEGF or its receptor may offer new therapeutic approaches. In this review, the authors integrate current knowledge of VEGF signaling and information on VEGF antagonists gleaned experimentally and place emphasis on the use of synthetic anti-VEGF hexapeptide to prevent VEGF interacting with its receptor.

The Impact

Abstract Background The full etiology of RA remains unclear; in addition to the contributions of infectious, hormonal, and environmental factors, several lines of evidence have suggested that the disease has a genetic basis. The VEGF gene is also an independent risk factor for RA severity and correlates with multiple disease parameters, such as disease activity, joint damage, and functional disability. This case-control study aimed to investigate the impact of a common genetic polymorphism in the vascular endothelial growth factor (VEGF) gene on disease activity and synovial lesions in patients with rheumatoid arthritis (RA). Results T allele was present in the RA group more frequently (22.5% vs. 10% respectively in controls). The C allele was less frequent in the RA group (77.7% vs. 90% respectively in controls) (P = 0.002). Homozygous genotype (CC) was found in 61.2% of patients and 82.5% of controls, homozygous genotype (TT) in 6.3% of patients, and 2.5% of controls while heterozygous (CT) genotype in 32.5% of patients and 15% of controls (P = 0.011). Grade 1 PDUS was found in 30.6% of CC and 11.5% of CT and not found in TT genotypes. The grade 2 was found in 69.4%, 65.4%, and only 20% of CC, CT, and TT genotypes, respectively. The grade 3 was found in 80% of TT, 23.1% of CT, and none of CC genotypes (P < 0.001). Conclusion An association between VEGF gene SNP rs3025039 and increased risk for RA among a sample of Egyptian population was noticed. VEGF gene polymorphism appears to be a potential diagnostic activity indicator and a promising therapeutic target for RA patients.

Hypoxia may lead to inflammatory responses by numerous signaling pathways. This investigation intended to inspect the defensive role of Quercetin (Quer) and/ or Melatonin (Mel) against reno toxicity induced by Sodium nitrite (Sod ntr). Sod ntr injection significantly decreased blood hemoglobin concentration (Hb) with a concurrent increase in serum tumor necrosis factor- α, interleukin-6, C-reactive protein, creatinine, and urea levels. Over protein-expression of vascular endothelial growth factor and heat shock, protein-70 and mRNA of HIF-1α were also observed. Pretreatment of the Sod ntr- injected rats with the aforementioned antioxidants; either alone or together significantly improved such parameters. Histopathological examination reinforced the previous results. It was concluded that the combined administration of Quer and Mel may be useful as a potential therapy against renal injury induced by Sod ntr. HIF-1α and HSP-70 are implicated in the induction of hypoxia and its treatment.
