Background: Guillain Barre syndrome (GBS) is an immune-mediated peripheral neuropathy characterized by the demyelination and axonal damage of the peripheral neurons. The pathogenesis of GBS involves the breakdown of the blood-brain barrier after which pro inflammatory cytokines attack the neurons in the peripheral nervous system. Aims: This study aims to evaluate five markers, namely matrix metalloproteinase (MMP)-2 and MMP-9, vascular endothelial growth factor (VEGF)-A, basic fibroblast growth factor (bFGF), and SFLT-1, which could have a role in the inflammatory response in patients with GBS and healthy controls. Settings and Design: In this prospective study, patients diagnosed with GBS at the department of neurology, Kasturba Medical College, Manipal, Karnataka were enrolled. Methods and Material: The markers selected for this study were analyzed using the ELISA method and expressed as given in the kit provided by the company. Ethical clearance was obtained from the Institutional Ethical Committee. Statistical Analysis: Results were evaluated using SPSS version 17.0 and expressed as mean ± SD. Error bars for each were drawn. Results: The levels of all five parameters showed a significant increase in patients as compared to controls. Conclusions: Disruption of the basement membrane of endoneurium by MMP-2 and MMP-9, recruitment and migration of macrophages and other cytokines by VEGF-A, bFGF, and soluble fms-like tyrosine kinase-1 (SFLT-1) are plausible, which leads to inflammation process and thus neuronal damage leading to the development of GBS.
