Increased lacrimal inflammatory mediators in patients with keratoconus.
Purpose: This study aimed to characterize the tear film immunologic profile in keratoconus (KC) patients compared with healthy individuals (control group) and to investigate the correlation between the tear film immunologic profile and atopy, disease severity, and disease status over time.
Methods: The study involved 30 KC patients and 18 healthy individuals. Tear collection was obtained using microcapillary tubes. Tear film levels of fractalkine, granulocyte-macrophage colony-stimulating factor (GM-CSF), interferon (IFN)-γ, interleukin (IL)-1β, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-10, IL-12, IL-13, IL-17A, IL-21, IL-23, interferon-inducible T-cell alpha chemoattractant (ITAC), macrophage inflammatory protein-1 alpha (MIP-1α), MIP-1β, MIP-3α, and tumor necrosis factor (TNF)-α were detected. Keratometric measurements and topographic patterns were used to diagnose and define disease progression. Tear immunologic profiles were compared, emphasizing the presence or absence of ocular allergy. Correlations between the cytokine profile, disease severity, and disease status were also analyzed longitudinally in the KC patients.
Results: Lacrimal cytokine concentrations were higher in the KC patients than they were in the controls in 14 of 21 cytokines analyzed. IL-6 was the most relevant cytokine found in KC patients, especially when associated with ocular allergy. There was no correlation between KC progression and the level of inflammatory cytokines when analyzed longitudinally. KC severity correlated with IL-6 concentration, where the more severe KC presented a higher IL-6 concentration in tears.
Conclusions: Inflammatory activity seems to be involved in the pathogenesis of KC. Out of 21 cytokines, 14 were more concentrated in the tears of KC patients than healthy subjects. IL-6 was significantly higher in KC patients' tears and was related to disease severity. Disease progression did not correlate with cytokine levels when analyzed longitudinally.
期刊介绍：
Molecular Vision is a peer-reviewed journal dedicated to the dissemination of research results in molecular biology, cell biology, and the genetics of the visual system (ocular and cortical).
Molecular Vision publishes articles presenting original research that has not previously been published and comprehensive articles reviewing the current status of a particular field or topic. Submissions to Molecular Vision are subjected to rigorous peer review. Molecular Vision does NOT publish preprints.
For authors, Molecular Vision provides a rapid means of communicating important results. Access to Molecular Vision is free and unrestricted, allowing the widest possible audience for your article. Digital publishing allows you to use color images freely (and without fees). Additionally, you may publish animations, sounds, or other supplementary information that clarifies or supports your article. Each of the authors of an article may also list an electronic mail address (which will be updated upon request) to give interested readers easy access to authors.
