Serum IL-6/ IL-10 Ratio As A Biomarker for Primary Open Angle Glaucoma Assessment
Abstract
Background: Substantial studies have been conducted on the function of interleukin-6 (IL-6) in various eye problems. While the versatile nature of IL-6 is well-documented, its primary role is to induce inflammation through its cytokine activity.
Objectives: The current work aimed to use serum IL-6 and IL-6/IL-10 ratio as potential biomarkers for primary open angle glaucoma (POAG) assessment.
Patients and Methods: 40 individuals were enrolled in this case-control study at Benha University hospitals' Ophthalmology, and Clinical and Chemical Pathology Departments. The participants were divided into two distinct groups: the case group consisted of twenty patients diagnosed with POAG and the control group included twenty healthy individuals who did not have glaucoma or any other ocular disorders. The cytokines levels of each participant were assessed using ELISA kits for serum IL-6 and IL-10.
Results: POAG and control groups showed no significant difference in age and sex. Regarding serum cytokines levels as diagnostic markers, POAG patients had a higher level of IL-6 and a lower level of IL-10 than control subjects. The IL-6 /IL-10 ratio displayed significantly higher values in POAG cases than controls. Regarding serum cytokines levels as prognostic markers, a significantly higher IL-6 level, and IL-6/IL-10 ratio were observed in the severe stage relative to the mild-moderate stages with no significant difference in the serum IL-10 levels.
Conclusions: It could be concluded that the serum IL-6 and IL-6/IL-10 ratio is potentially useful as biomarkers for diagnosis and evaluation of the severity of POAG. Consistently monitoring serum concentrations of IL-6 and IL-10 may be used as supplementary laboratory methods in the POAG assessment.
