Abstract
PURPOSE
To evaluate prediagnostic markers of endothelial dysfunction and inflammatory processes in primary open-angle glaucoma (POAG).
METHODS
Blood samples were collected from 1989 to 1990 in the nurses' health study (women) and from 1993 to 1995 in the health professionals follow-up study (men), and medical-record confirmed incident poag cases were identified (women: 229 cases and 455 controls; men: 116 cases and 228 controls). Controls were matched on cohort, age, race, ethnicity, cancer status, and date of blood collection. Plasma concentrations of ICAM-1, E-selectin, and soluble TNF receptor 2 (sTNF-R2), a marker related to TNF-α, were measured with ELISA assays. Cohort-specific multivariable conditional logistic regression model results were meta-analyzed.
RESULTS
We observed no associations with ICAM-1 or E-selectin. for sTNF-R2, the mean (SD) plasma levels (pg/ml) in cases and controls were 2888 (997) and 2993 (913), respectively, in women; and 2622 (664) and 2569 (688), respectively, in men. pooled multivariable results showed no relation between sTNF-R2 levels and POAG. however, compared with the lowest tertile of sTNF-R2, the highest tertile showed a significant decreased risk of POAG in women (multivariable odds ratio [OR] = 0.58, 95% confidence interval [CI] = 0.360.93; P(trend) = 0.03) but not in men (P(trend) = 0.21; P for heterogeneity by sex = 0.03). also, among women, the inverse association with sTNF-R2 was stronger with normal-tension glaucoma (ntg; maximum intraocular pressure 21 mm Hg at diagnosis): highest versus lowest tertile comparison OR = 0.29 (95% CI = 0.12-0.71; Ptrend = 0.007).
CONCLUSIONS
In women, but not in men, higher sTNF-R2 levels at 6 to 8 years before diagnosis were inversely associated with POAG, but more strongly for NTG.
