چکیده انگلیسی
Dry eye disease (DED) is a complex, multifactorial pathology characterized by corneal epithelium lesions and inflammation. The aim of the present study was to evaluate the efficacy of a cationic emulsion of cyclosporine A (CsA) in a mouse model that mimics severe dry eye. Eight to 12-week-old female C57BL/6N mice with tail patches of scopolamine were housed in controlled environment chambers to induce dry eye. At day three, following dry eye confirmation by corneal fluorescein staining (CFS, score 0-15) and phenol red thread (PRT) lacrimation test, the mice (n = 10/gp) were either treated 3 times a day in both eyes with drug-free cationic emulsion, a 0.1% CsA cationic emulsion, or 1% methylprednisolone (positive control), or non-treated. Aqueous tear production and CFS scores were evaluated at baseline and throughout the treatment period. The lacrimation test confirmed the scopolamine-induced decrease in aqueous production by the lacrimal gland. A reduction of 59% in induced-CFS was observed following topical treatment with 0.1% CsA. The beneficial effect of the cationic emulsion vehicle itself on keratitis was also clearly evidenced by its better performance over 1% methylprednisolone, -36%, vs. -28% on the CFS scores, respectively. This study indicates that the cationic emulsion of CsA (0.1%) was a very effective formulation for the management of corneal epithelium lesions in a severe DED mouse model. In addition, it performed better than a potent glucocorticosteroid (1% methylprednisolone). This cationic emulsion of CsA (0.1%), combining CsA and a tear film oriented therapy (TFOT), i.e. with vehicle properties that mechanically stabilize the tear film, represents a promising new treatment strategy for the management of the signs of dry eye.
