Two Patients with Dry Eye Disease Followed Up Using an Expression Assay of Ocular Surface Mucin

چکیده
Purpose: We report 2 patients with dry eye disease followed up using the expression levels of ocular surface mucin. Case Reports: Patient 1: a 57-year-old woman with Sjögren’s syndrome-associated dry eyes experienced severe dryness and foreign body sensation in both her eyes, and instilled sodium hyaluronate ophthalmic solution 0.3% about 10–15 times daily. We measured the expression levels of MUC5AC mRNA (MUC5AC) and MUC16 mRNA (MUC16) by using real-time reversed transcription polymerase chain reaction for the specimens of modified impression cytology. Expression levels of MUC5AC and MUC16 on her ocular surface were very low. Subjective symptoms and expression levels of ocular surface mucin improved after combined treatment of rebamipide (4 times daily) and fluorometholone (once daily) ophthalmic suspension. Patient 2: a 62-year-old man with chronic graftversus-host disease-associated dry eye experienced severe foreign body sensation and developed superficial punctate keratopathy with mucous thread and filamentary keratitis. Expression level of MUC5AC was very high at baseline. Subjective symptoms and expression levels of ocular surface mucin improved by combined treatment of rebamipide (4 times daily) and fluorometholone (once daily) ophthalmic suspension. Conclusion: Clinical test for MUC gene expression on the ocular surface was found to be useful in the follow-up of dry eye treatment. © 2016 The Author(s) Published by S.

Quantification of MUCIN 1, cell surface associated and MUCIN16, cell surface associated proteins in tears and conjunctival epithelial cells collected from postmenopausal women
PURPOSE To quantify the expression of mucin 1, cell surface associated (MUC1) and mucin 16, cell surface associated (MUC16) proteins and messenger ribonucleic acid (mRNA) in a cohort of postmenopausal women (PMW), to explore the relationship between mucin expression, dry eye symptomology, and tear stability. METHODS Thirty-nine healthy PMW (>50 years of age) were enrolled in this study. No sp...
متن کاملInvestigating Ocular Diseases in Patients with Psoriasis
Background and purpose: Psoriasis is an inflammatory disease with skin and joint manifestations. This disease can be associated with ocular complications and reduce vision and quality of life. The aim of this study was to determine the prevalence and type of ocular involvement in patients with psoriasis to prevent unwanted complications by identifying the disease at the right time. Materials a...
متن کاملOcular surface mucins and local inflammation—studies in genetically modified mouse lines
Mucins locate to the apical surfaces of all wet-surfaced epithelia including ocular surface. The functions of the mucins include anti-adhesive, lubrication, water retention, allergens and pathogen barrier function. Ocular surface pathologies, i.e. dry eye syndrome or allergic conjunctivitis, are reportedly associated with alteration of expression pattern of mucin components. Recent investigatio...
