The high expression of the pain-related inflammatory factors in the eyes of cataract patients infected with hepatitis B virus.

In cataract surgery, it is often found that patients infected hepatitis B virus (HBV) are likely to suffer from more pain than other patients. In order to assess the inflammation status of the aqueous humor in the eyes of cataract patients infected with HBV. RayBio Human Inflammation Array was used to assay aqueous humor samples collected from 14 eyes of patients infected with HBV and 14 eyes of cataract patients without HBV infection (the controls) during the cataract surgery. RayBio Human Quantibody Cutom Array was adopted for the validation of the screened cytokines, with aqueous humor samples collected from 40 eyes of patients infected with HBV and 40 eyes of the controls. A pain questionnaire survey about the surgery was conducted in all patients after operation. The results of questionnaire showed that patients infected with HBV were more likely to have pain during operation. The Human Inflammation Array revealed that the expression levels of monocyte chemoattractant protein-1 (MCP-1), tumor necrosis factor α (TNF-α) and tumor necrosis factor ß (TNF-ß) were very high in HBV infected patients and IL-1ra was much lower in patients infected with HBV (all, P < 0.05). In validation, the Human Quantibody Cutom Array revealed that the expression levels of MCP-1 and TNF-α were high in HBV infected patients with significant difference (all P < 0.05). These results revealed that pain-related inflammatory factors MCP-1 and TNF-α were increased in aqueous humor of cataract patients infected with HBV, which indicates that patients infected with HBV may be more prone to intraoperative pain.
