BACKGROUND/AIMS: To assess 24 pro-inflammatory cytokines in the aqueous and serum of normal patients without diabetes.
METHODS: 94 consecutive eyes of 94 patients undergoing elective vitrectomy surgery were prospectively enrolled. Blood and aqueous sampling were done in the operating room. A microparticle bead-based multiplex assay was used to measure aqueous and serum levels of: fibroblast growth factor-2, eotaxin, granulocyte colony stimulating factor (G-CSF), FMS-like tyrosine kinase 3 ligand (FLT-3L), growth-regulated alpha protein (GROa), interleukin (IL)-10, monocyte chemotactic protein (MCP)-3, macrophage-derived chemokine (MDC), soluble CD40L (sCD40L), IL-17A, interleukin-1 receptor antagonist (IL-1RA), IL-1β, IL-2, IL-4, IL-6, IL-8, interferon gamma-induced protein 10 (IP-10), MCP-1, macrophage inflammatory protein-1β, tumour necrosis factor-α, vascular endothelial growth factor (VEGF), regulated on activation normal T expressed and secreted (RANTES), platelet-derived growth factor (PDGF)-AA and PDGF-AB/BB.
RESULTS: A significant positive correlation between aqueous and serum levels was observed for FLT-3L (r=0.45; p<0.001) and positive trends were observed for eotaxin (r=0.27; p=0.04), MDC (r=0.34; p<0.01) and RANTES (r=0.33; p=0.007). There were no significant differences observed based on age or gender. In contrast, aqueous cytokine levels for G-CSF, GROa and MCP-1 were significantly higher in pseudophakic eyes compared with phakic eyes: G-CSF (16.52 pg/mL±22.39 vs 2.77 pg/mL±6.80, p<0.0001), GROa (12.45 pg/mL±6.54 vs 8.26 pg/mL±5.48, p=0.001) and MCP-1 (1340.51 pg/mL±565.21 vs 830.44 pg/mL±454.36, p<0.0001), respectively.
CONCLUSIONS: We report the first characterisation of 24 different pro-inflammatory cytokines in 94 patients without diabetes. The absence of the crystalline lens was associated with significantly higher aqueous levels of G-CSF, GROa and MCP-1.
