The Efficacy and Safety of Rebamipide Ophthalmic Suspension (OPC-12759) in Patients with Dry Eye Disease: A Systematic Review of Randomized Controlled Trials. J Clin Med 2023; 12:7155. [PMID: 38002767 PMCID: PMC10672675 DOI: 10.3390/jcm12227155] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 10/24/2023] [Accepted: 11/16/2023] [Indexed: 11/26/2023] Open
Abstract
The aim of this paper is to evaluate the efficacy and safety of Rebamipide (REB) ophthalmic suspension in dry eye disease (DED). A systematic review that only included full-length randomized controlled studies (RCTs) reporting the effects of REB ophthalmic suspension in three databases, PubMed, Scopus and Web of Science, was performed according to the PRISMA statement. The Cochrane risk of bias tool was used to analyze the quality of the studies selected. A total of seven studies were included in this systematic review. Although the overall risk of bias was low, most studies were sponsored by the manufacturer. REB ophthalmic suspension treatment achieved higher improvement than the control group in all reported variables. The mean differences between both groups were in favor of the REB group and were as follows: dry eye-related quality of life score (DEQS) -3.5 ± 2.9 points, tear film break-up time (TBUT) of 0.7 ± 0.6 s, Schirmer test (ST) without anesthesia of 0.3 ± 0.6 mm and total corneal fluorescein staining (tCFS) of -1.2 ± 0.7 points. Adverse events (AEs) were 5.2 ± 7.6% superior in the REB group, with an overall compliance > 95%. Therefore, REB ophthalmic suspension is a safe and effective treatment that could be recommended in patients with DED.

Abstract
OBJECTIVE To evaluate the presence of wiper epitheliopathy in patients with blepharospasm and/or hemifacial spasm before and 4 weeks after routine treatment with botulinum toxin. METHODS Prospective study comprising 31 eyes of 20 patients with neurological diagnosis of hemifacial spasm (9 eyes of 9 patients) and essential blepharospasm (22 eyes of 11 patients). Various ocular surface parameters were assessed before and 4 weeks after infiltration with botulinum toxin using the OSDI questionnaire, Schirmer's test, tear break-up time (BUT), fluorescein and lissamine green staining assessed with the Oxford test and the degree of involvement of the palpebral wiper. RESULTS 100% of the patients had palpebral wiper involvement before (30% mild and 70% moderate) and after toxin treatment (100% mild). 75% of patients had mild-normal OSDI before treatment, after treatment it was 80%. The BUT was 7.2 ± 0.2 sg before and 7.5 ± 0.7 sg after treatment. Schirmer's test was 11.4 ± 5.5 and 12.5 ± 5.5 mm before and after treatment. The Oxford test was initially pathological in 69.3% of patients, after 4 weeks it was pathological in only 54%. CONCLUSION Wiper epitheliopathy is present in 100% of patients with blepharospasm and/or hemifacial spasm. The main pathophysiological mechanism that triggers it in these patients is the increase in the coefficient of friction, as tear volume and stability are normal.

Clinical Factors for Determining the Severity of Lid Wiper Epitheliopathy in Dry Eye. Cornea 2021; 41:545-551.

Abstract
PURPOSE Lid wiper epitheliopathy (LWE) is an epitheliopathy of the marginal conjunctival portion of the eyelids that wipes the ocular surface during blinking. Although LWE is often observed in patients with dry eye, the factors determining LWE severity in dry eye remain unknown. Therefore, we investigated the relationship between LWE, tear abnormalities, and blinks in dry eye. METHODS This study involved 76 eyes of 76 female patients with dry eye (mean age: 57.2 yrs). In all eyes, tear meniscus radius, spread grade (SG) of the tear film lipid layer (ie, SG 1-5, with 1 being the best), fluorescein breakup time (FBUT), fluorescein breakup pattern, corneal and bulbar conjunctival epithelial damage (CED: 15 points maximum; CjED: 6 points maximum, respectively), upper eyelid LWE grade (3 points maximum), and Schirmer 1 test were evaluated. Blink rate, palpebral aperture height, upper eyelid opening/closing-phase amplitude, upper eyelid opening/closing-phase duration, and upper eyelid opening/closing-phase maximum velocity were measured by the use of a custom-made high-speed blink analyzer. Finally, the factors that determine the LWE grade were investigated by multiple regression analysis, in which the parameters were chosen using the stepwise procedure. RESULTS Significant correlations were found between LWE grade and tear meniscus radius, SG, FBUT, CED, CjED, and Schirmer 1 test (P < 0.002). LWE grade was found to be described as -0.001 + (0.283 × SG) - (0.253 × FBUT) + (0.003 × upper eyelid closing-phase maximum velocity) (R2 = 0.57, P < 0.0001). The prevalence and grade of LWE were significantly higher in aqueous deficient dry eye. CONCLUSIONS Tear volume, tear film stability, and blink should be considered as factors for determining LWE severity.

Assessment of mucin-related gene alterations following treatment with rebamipide ophthalmic suspension in Sjögren's syndrome-associated dry eyes. PLoS One 2020; 15:e0242617.

Abstract
Ocular surface mucins are thought to play vital roles in maintaining the homeostasis of the pre-ocular surface tear film. We performed ocular surface tests with impression cytology to assess the expression levels of mucin-related genes on the ocular surface in healthy eyes. In addition, we investigated alterations in mucin-related gene expression secondary to treatment with rebamipide ophthalmic suspension in patients with Sjögren’s syndrome-associated dry eyes (SS-DE). Thirty-three healthy individuals (control group) and 13 patients from our hospital with SS-DE were enrolled. Impression cytology was performed using Schirmer’s test paper for RNA sampling. The mRNA levels of SAM-pointed domain-containing ETS-like factor (SPDEF), mucin 5AC (MUC5AC), and mucin 16 (MUC16) were determined using a real-time reverse transcription-polymerase chain reaction. The ocular surface test was performed once for the control group, and at baseline as well as 2, 4, 8, and 12 weeks after treatment in the Sjögren’s syndrome-associated dry eyes group. mRNA levels of SPDEF, MUC5AC, and MUC16 were not significantly different between the control and SS-DE groups before rebamipide ophthalmic suspension treatment. SPDEF mRNA levels in control subjects were significantly correlated with levels of MUC5AC. Among SS-DE patients, SPDEF mRNA levels were significantly increased at 2, 4, and 8 weeks after treatment compared with baseline levels. MUC16 mRNA levels were significantly decreased from baseline levels at 4 and 8 weeks post-treatment. Ocular surface test using impression cytology is a clinically useful tool for assessing mucous conditions on the ocular surface and can be used to determine the effects of instillation treatment with eye drops that affect mucin production at the ocular surface.

Abstract
The 2017 consensus report of the Asia Dry Eye Society (ADES) on the definition and diagnosis of dry eyes described dry eye disease as "Dry eye is a multifactorial disease characterized by unstable tear film causing a variety of symptoms and/or visual impairment, potentially accompanied by ocular surface damage." The report emphasized the instability of tear film and the importance of visual dysfunction in association with dry eyes, highlighting the importance of the evaluation of tear film stability. This report also discussed the concept of tear film-oriented therapy, which stemmed from the definition, and which is centered on provision of insufficient components in each tear film layer and ocular surface epithelium. The current ADES report proposes a simple classification of dry eyes based on the concept of tear film-oriented diagnosis and suggests that there are three types of dry eye: aqueous-deficient, decreased wettability, and increased evaporation. It is suggested that these three types respectively coincide with the problems of each layer: aqueous, membrane-associated mucins, and lipid/secretory mucin. Although each component cannot be quantitatively evaluated with the current technology, a practical diagnosis based on the patterns of fluorescein breakup is recommended. The Asia Dry Eye Society classification report suggests that for a practical use of the definition, diagnostic criteria and classification system should be integrated and be simple to use. The classification system proposed by ADES is a straightforward tool and simple to use, only through use of fluorescein, which is available even to non-dry eye specialists, and which is believed to contribute to an effective diagnosis and treatment of dry eyes.

Abstract
Instability of the tear film (TF) protecting the ocular surface results in dry eye syndrome (DES), the most prevalent public health ophthalmic disease affecting the quality of life of 10 to 30% of the human population worldwide. Although the impact of the tear film lipid layer (TFLL) and of the aqueous tears (AT) to the TF stability is extensively studied, in contrast the contribution of the secretory mucins (SM) and of the membrane-associated mucins (MAM), i.e., one of the most abundant molecular classes in AT and in the corneal epithelium respectively, remains poorly defined. However, it is well known that in DES both types of mucins are quantitatively or qualitatively deficient. Numerous studies since the 1990s until now have proposed direct involvement of SM and MAM in the material properties (viscoelasticity, hydration, and protection of the ocular surface; synergistic cooperation with the rest of the TF layers; etc.) and stability of TF. These theories will be reviewed here in the context of the classical and modern in vitro and in vivo results that allow their reappraisal and in view of the novel mucin secretion enhancing pharmaceuticals, which have opened innovative routes for the therapy of DES.

Abstract
Mucins, which play important roles on the ocular surface in wettability, lubrication, and barrier function, are classified into two categories: secreted mucins and membrane-associated mucins. The most important secreted mucin on the ocular surface is MUC5AC, which is secreted by the conjunctival goblet cells. In the human conjunctiva, goblet cells are present in higher concentrations in the fornix, inferior nasal bulbar, and the lid wiper on the lid margin. The number of conjunctival goblet cells and MUC5AC expression/secretion are decreased in a patient with dry eye. In Japan, drugs that stimulate mucin secretion or increase the number of conjunctival goblet cells are commercially available. A P2Y2 receptor, diquafosol, stimulates tear fluid secretion from conjunctival epithelial cells and promotes mucin secretion from conjunctival goblet cells. Rebamipide was marketed originally as an oral therapeutic drug to treat gastritis in Japan. Topical rebamipide increases numbers of goblet cells in the bulbar conjunctiva and the lid wiper area of palpebral conjunctiva. Many researchers have reported decreases in the ocular surface mucin expression including MUC5AC secreted by goblet cells in patients with dry eye. However, it is unknown whether changes in mucin expression on the ocular surface cause or result from dry eye. Further study is needed to determine the true mechanism of dry eye disease.

Abstract
The underlying mechanisms of dry eye are thought to be part of a vicious circle involving a hyperosmolarity-triggered inflammatory cascade, resulting in loss of goblet cells and glycocalyx mucin and observed corneal and conjunctival epithelial cell damage. This damage leads to increased tear film instability, further hyperosmolarity and hence perpetuating of a vicious circle. The aim of dry eye management is to restore the homeostasis of the tear film and break the perpetuation of this vicious circle. Despite the plethora of treatment options available, many of these are largely palliative, short-lived and require repeated instillations. Two emerging areas in dry eye therapy aim to promote tear secretion and to safely manage dry eye-associated inflammation and are the focus of this review.

Abstract
Mucins are key actors in tear film quality and tear film stability. Alteration of membrane-bound mucin expression on corneal and conjunctival epithelial cells and/or gel-forming mucin secretion by goblet cells (GCs) promotes in ocular surface diseases and dry eye disease (DED). Changes in the mucin layer may lead to enhanced tear evaporation eventually contributing to tear hyperosmolarity which has been associated with ocular surface inflammation. Inflammatory mediators in turn may have a negative impact on GCs differentiation, proliferation, and mucin secretion. This sheds new light on the position of GCs in the vicious circle of DED. As contributor to ocular surface immune homeostasis, GC loss may contribute to impaired ocular surface immune tolerance observed in DED. In spite of this, there are no tools in routine clinical practice for exploring ocular surface mucin deficiency/dysregulation. Therefore, when selecting the most appropriate treatment options, there is a clear unmet need for a better understanding of the importance of mucins and options for their replacement. Here, we comprehensively revisited the current knowledge on ocular surface mucin biology, including functions, synthesis, and secretion as well as the available diagnostic tools and treatment options to improve mucin-associated homeostasis. In particular, we detailed the potential link between mucin dysfunction and inflammation as part of the uncontrolled chronic inflammation which perpetuates the vicious circle in DED.

Abstract
The purpose of the study was to compare the two mucin secretogogues, diquafosol (DQS) and rebamipide (RBM), for the treatment of dry eye syndrome (DES) in office workers. Dry eye patients using computers for >4 h/day were randomly assigned treatment with either DQS or RBM. Main outcomes measures included changes in tear film break-up time (TBUT) and subjective symptoms assessed by the Dry Eye-Related Quality of Life Score (DEQS). The subjects had scheduled examinations at 0 and 4 weeks, and the examinations at 2 and 8 weeks were optional. Changes in keratoconjunctival fluorescein score and a patient satisfaction questionnaire were also recorded. Both groups showed significant improvements in the DEQS scores at 2, 4, and 8 weeks following the initiation of the study. Both groups showed significant increases in the TBUT at 2 and 4 weeks. No significant difference was found between the DQS and RBM groups at any time periods. Patients reported more comfort with the use of DQS compared with the use of RBM. No local or systemic side effects were noted. The results of the present study indicated that both DQS and RBM were effective for the treatment of DES in office workers.
