Executive summary: Japanese guidelines for allergic conjunctival diseases 2021.

Allergic conjunctival disease (ACD) is an inflammatory disease of the conjunctiva that is mainly caused by type I hypersensitivity response to allergens and accompanied by subjective symptoms and other findings induced by antigens. ACD is classified as allergic conjunctivitis, atopic keratoconjunctivitis, vernal keratoconjunctivitis, and giant papillary conjunctivitis. This article summarizes the third edition of the Japanese guidelines for allergic conjunctival diseases published in 2021 and outlines the diagnosis, pathogenesis, and treatment of ACD. Since the introduction of immunosuppressive eye drops, the treatment strategies for severe ACDs have significantly changed. To clarify the recommended standard treatment protocols for ACD, the advantages and disadvantages of these treatments were assessed using clinical questions, with a focus on the use of steroids and immunosuppressive drugs. This knowledge will assist healthcare providers and patients in taking an active role in medical decision making.

Japanese guidelines for allergic conjunctival diseases 2020.

The definition, classification, pathogenesis, test methods, clinical findings, criteria for diagnosis, and therapies of allergic conjunctival disease are summarized based on the Guidelines for Clinical Management of Allergic Conjunctival Disease 2019. Allergic conjunctival disease is defined as "a conjunctival inflammatory disease associated with a Type I allergy accompanied by some subjective or objective symptoms." Allergic conjunctival disease is classified into allergic conjunctivitis, atopic keratoconjunctivitis, vernal keratoconjunctivitis, and giant papillary conjunctivitis. Representative subjective symptoms include ocular itching, hyperemia, and lacrimation, whereas objective symptoms include conjunctival hyperemia, swelling, folliculosis, and papillae. Patients with vernal keratoconjunctivitis, which is characterized by conjunctival proliferative changes called giant papilla accompanied by varying extents of corneal lesion, such as corneal erosion and shield ulcer, complain of foreign body sensation, ocular pain, and photophobia. In the diagnosis of allergic conjunctival diseases, it is required that type I allergic diathesis is present, along with subjective and objective symptoms accompanying allergic inflammation. The diagnosis is ensured by proving a type I allergic reaction in the conjunctiva. Given that the first-line drug for the treatment of allergic conjunctival disease is an antiallergic eye drop, a steroid eye drop will be selected in accordance with the severity. In the treatment of vernal keratoconjunctivitis, an immunosuppressive eye drop will be concomitantly used with the abovementioned drugs.

Clinical practice guideline for Sjögren's syndrome 2017.

OBJECTIVES: The objective of this study is to develop clinical practice guideline (CPG) for Sjögren's syndrome (SS) based on recently available clinical and therapeutic evidences. METHODS: The CPG committee for SS was organized by the Research Team for Autoimmune Diseases, Research Program for Intractable Disease of the Ministry of Health, Labor and Welfare (MHLW), Japan. The committee completed a systematic review of evidences for several clinical questions and developed CPG for SS 2017 according to the procedure proposed by the Medical Information Network Distribution Service (Minds). The recommendations and their strength were checked by the modified Delphi method. The CPG for SS 2017 has been officially approved by both Japan College of Rheumatology and the Japanese Society for SS. RESULTS: The CPG committee set 38 clinical questions for clinical symptoms, signs, treatment, and management of SS in pediatric, adult and pregnant patients, using the PICO (P: patients, problem, population, I: interventions, C: comparisons, controls, comparators, O: outcomes) format. A summary of evidence, development of recommendation, recommendation, and strength for these 38 clinical questions are presented in the CPG. CONCLUSION: The CPG for SS 2017 should contribute to improvement and standardization of diagnosis and treatment of SS.

Comparison of performance of the 2016 ACR-EULAR classification criteria for primary Sjögren's syndrome with other sets of criteria in Japanese patients.

OBJECTIVES: To compare the performance of the new 2016 American College of Rheumatology (ACR)-European League Against Rheumatism (EULAR) classification criteria for primary Sjögren's syndrome (SS) with 1999 revised Japanese Ministry of Health criteria for diagnosis of SS (JPN), 2002 American-European Consensus Group classification criteria for SS (AECG) and 2012 ACR classification criteria for SS (ACR) in Japanese patients. METHODS: The study subjects were 499 patients with primary SS (pSS) or suspected pSS who were followed up in June 2012 at 10 hospitals in Japan. All patients had been assessed for all four criteria of JPN (pathology, oral, ocular, anti-SS-A/SS-B antibodies). The clinical diagnosis by the physician in charge was set as the 'gold standard'. RESULTS: pSS was diagnosed in 302 patients and ruled out in 197 patients by the physician in charge. The sensitivity of the ACR-EULAR criteria in the diagnosis of pSS (95.4%) was higher than those of the JPN, AECG and ACR (82.1%, 89.4% and 79.1%, respectively), while the specificity of the ACR-EULAR (72.1%) was lower than those of the three sets (90.9%, 84.3% and 84.8%, respectively). The differences of sensitivities and specificities between the ACR-EULAR and other three sets of criteria were statistically significant (p<0.001). Eight out of 302 patients with pSS and 11 cases out of 197 non-pSS cases satisfied only the ACR-EULAR criteria, compared with none of the other three sets. CONCLUSIONS: The ACR-EULAR criteria had significantly higher sensitivity and lower specificity in diagnosis of pSS, compared with the currently available three sets of criteria.

Steroid-Sparing Effect of 0.1% Tacrolimus Eye Drop for Treatment of Shield Ulcer and Corneal Epitheliopathy in Refractory Allergic Ocular Diseases.

PURPOSE: To evaluate the effects of 0.1% topical tacrolimus alone or in combination with steroids for the treatment of shield ulcers and corneal epitheliopathy in patients with refractory allergic ocular diseases. DESIGN: Open cohort study. PARTICIPANTS: Patients with refractory allergic conjunctivitis epitheliopathy, shield ulcers, or corneal plaques (N = 791). METHODS: The 791 patients were treated with topical tacrolimus alone or in combination with topical or oral steroids. The effectiveness of the treatments was determined by a corneal epitheliopathy score during the 3-month follow-up period. The clinical signs were rated on a 4-grade scale. Corneal epitheliopathy with no corneal staining was graded as 0, and shield ulcers or plaques were graded as 3, the highest grade. The effects of tacrolimus with and without topical steroids on the epitheliopathy scores were assessed after adjustments for the severity of the clinical signs and characteristics. MAIN OUTCOME MEASURES: Changes in the corneal epitheliopathy score. RESULTS: Adjusted mean epitheliopathy score at the baseline was 1.73 (95% confidence interval [CI], 1.65-1.81) for patients treated with tacrolimus alone, and this was significantly reduced by -0.93 at 1 month. The reduction of the score by topical and oral steroids was -0.02 for fluorometholone, 0.02 for betamethasone, and -0.02 for oral steroids, and these reductions were not significant compared with the reduction effect of topical tacrolimus alone at -0.93. The 238 patients with shield ulcer (score 3) were analyzed with adjustments, and the mean epitheliopathy score at 1 month was reduced to 1.38 with tacrolimus alone (95% CI, 1.24-1.51), 1.41 (95% CI, 1.26-1.56) with adjuvant fluorometholone, and 1.46 (95% CI, 1.32-1.61) with adjuvant betamethasone. No significant difference was observed in the adjunctive topical steroids. The presence of severe palpebral conjunctival symptoms, including giant papillae, was a significant resisting factor for topical tacrolimus. CONCLUSIONS: The significant effects of topical tacrolimus alone on shield ulcers and corneal epitheliopathy suggest that it may be used without the need for steroids.

Efficacy of epinastine hydrochloride ophthalmic solution in allergic conjunctivitis by conjunctival cedar pollen allergen challenge.

BACKGROUND: Epinastine hydrochloride is a selective histamine H1 receptor antagonist that also inhibits IgE receptor-mediated histamine release from mast cells. OBJECTIVE: To show the superiority of epinastine 0.05% ophthalmic solution (epinastine) to placebo ophthalmic solution (placebo) and noninferiority to olopatadine 0.1% ophthalmic solution (olopatadine) for cedar pollen antigen-induced ocular itching and conjunctival hyperemia. METHODS: The study was conducted in ophthalmologically asymptomatic adult volunteers with seasonal allergic conjunctivitis using a conjunctival allergen challenge test. Subjects were randomized into 3 groups (n = 87) to evaluate superiority to placebo (visits 4 to 6) and 2 groups (n = 86) to evaluate noninferiority to olopatadine (visit 7). At each visit, a single administration of the study medication was instilled at 15 minutes (visit 4), 4 hours (visit 5), 8 hours (visit 6), and 4 hours (visit 7) before the conjunctival allergen challenge test. Ocular itching and conjunctival hyperemia of allergic conjunctivitis were assessed after the conjunctival allergen challenge test. RESULTS: For the primary end point, epinastine showed superiority to placebo for the inhibition of ocular itching and conjunctival hyperemia induced at 4 hours after the dose (equivalent to 4-times-daily dosing). For the secondary end points, epinastine significantly inhibited itching and conjunctival hyperemia induced at 15 minutes and 8 hours after the dose (equivalent to 2-times-daily dosing) compared with placebo. In addition, epinastine demonstrated noninferiority to olopatadine for ocular itching and conjunctival hyperemia. No adverse drug reactions or serious adverse events were reported throughout the study, indicating that epinastine has a good safety profile. CONCLUSION: Epinastine is effective and safe for the treatment of allergic conjunctivitis. TRIAL REGISTRATION: Clinicaltrials.gov identifier NCT01363700.

Primary and secondary surveys on epidemiology of Sjögren's syndrome in Japan.

OBJECTIVE: To characterize the epidemiology of Sjögren's syndrome (SS), including prevalence, disease type, extra-glandular involvement, satisfaction of diagnostic criteria sets, and treatment used in Japan. METHODS: The Research Team for Autoimmune Diseases, the Research Program for Intractable Disease by the Ministry of Health, Labor and Welfare conducted primary and secondary surveys on epidemiology of SS in 2011. The primary survey covered 4,729 out of 14,095 Japan-wide Hospital Departments to investigate the prevalence of SS. The secondary survey encompassed 214 Hospital Departments that agreed to the survey, to characterize disease type, extra-glandular involvement, satisfaction of diagnostic criteria sets, and treatments. RESULTS: The number of patients with SS in Japan estimated by the primary survey was 68,483. The secondary survey involving data collected from 2,195 SS patients from 98 Hospital Departments showed that the mean age of patients was 60.8 ± 15.2 years, male/female ratio was 1/17.4, primary/secondary SS was about 60%/40% and glandular/extra-glandular form in primary SS was about 70%/25%. The satisfaction rate was 53.8% for the 1999 revised Japanese Ministry of Health criteria for the diagnosis of SS, 47.7% for the 2002 American-European Consensus Group classification criteria for SS and 49.6% for 2012 American College of Rheumatology classification criteria for SS. Corticosteroids were used by 752 of 2,195 patients (34%), immunosuppressants by 358 patients (16%), biologics by 68 patients (3%) and secretagogues by 695 patients (32%). CONCLUSION: The surveys provided valuable information on the epidemiology of SS including prevalence, disease type, extra-glandular involvement, satisfaction of diagnostic criteria sets and treatments used today in Japan.

Validation of different sets of criteria for the diagnosis of Sjögren's syndrome in Japanese patients.

OBJECTIVE: To validate the revised Japanese Ministry of Health criteria for the diagnosis of Sjögren's syndrome (SS) (JPN) (1999), The American-European Consensus Group classification criteria for SS (AECG) (2002), and American College of Rheumatology classification criteria for SS (ACR) (2012). METHODS: The study subjects were 694 patients with SS or suspected SS who were followed-up in June 2012 at ten hospitals that form part of the Research Team for Autoimmune Diseases, The Research Program for Intractable Disease by the Ministry of Health, Labor and Welfare (MHLW). All patients had been checked for all four criteria of the JPN (pathology, oral, ocular, anti-SS-A/SS-B antibodies). We studied the clinical diagnosis made by the physician in charge and the satisfaction of the above criteria. RESULTS: Of the 694 patients, 499 patients did not have other connective tissue diseases (CTDs). SS was diagnosed in 476 patients (primary SS in 302, secondary SS in 174), whereas non-SS was diagnosed in 218 patients (without other CTDs in 197, with other CTDs in 21) by the physician in charge. The sensitivities of JPN, AECG, and ACR in the diagnosis of all forms of SS (both primary and secondary SS) were 79.6, 78.6, and 77.5 %, respectively, with respective specificities of 90.4, 90.4, and 83.5 %. The sensitivities of the same systems in the diagnosis of primary SS were 82.1, 83.1, and 79.1 %, respectively, with specificities of 90.9, 90.9, and 84.8 %, respectively. The sensitivities of the same systems in the diagnosis of secondary SS were 75.3, 70.7, and 74.7 %, respectively, with specificities of 85.7, 85.7, and 71.4 %, respectively. CONCLUSION: The sensitivity of JPN to all forms of SS and secondary SS, the sensitivity of AECG to primary SS, and the specificities of JPN and AECG for all forms of SS, primary SS, and secondary SS were highest in the diagnosis of SS in Japanese patients. These results indicate that the JPN criteria for the diagnosis of SS in Japanese patients are superior to ACR and AECG.

Blood level of tacrolimus in patients with severe allergic conjunctivitis treated by 0.1% tacrolimus ophthalmic suspension.

BACKGROUND: To estimate the efficacy and safety of 0.1% tacrolimus ophthalmic suspension based on the blood level of tacrolimus in patients with severe allergic conjunctivitis. METHODS: Fifty-two patients in whom topical anti-allergic agents had been ineffective were treated with 0.1% tacrolimus ophthalmic suspension twice daily for 12 weeks. Adverse drug reactions were monitored, as well as ocular symptoms and signs. The blood concentration of tacrolimus was measured before the initiation of treatment and 4 and 12 weeks later. RESULTS: About 75% of the patients without concomitant using of tacrolimus ointment had blood levels of tacrolimus below the detection limit of the assay (0.5ng/mL). On the other hand, 71% (week 4) and 57% (week 12) of patients with concomitant using of tacrolimus ointment had blood levels above the detection limit of the assay. However, the maximum blood concentration was less than 2ng/mL. Adverse drug reactions occurred in 16 patients. These were disorders of the eye such as warmness, irritation, and a burning sensation. However, all of the patients could continue treatment with tacrolimus for 12 weeks. There were no serious adverse events such as increased intraocular pressure or ocular infection during the study. All symptoms and signs improved over time. CONCLUSIONS: The good safety profile of 0.1% tacrolimus ophthalmic suspension based on the low blood concentration of tacrolimus, coupled with demonstrated efficacy, make it an important tool for treating severe allergic conjunctivitis.

[Evaluation of the efficacy of subjective symptoms, objective findings, and of a total tear IgE detection kit in diagnosis of allergic conjunctival diseases].

PURPOSE: To evaluate the efficacy of subjective symptoms, objective findings, and of a total tear IgE test kit in the diagnosis of allergic conjunctival diseases (ACD). SUBJECTS AND METHODS: The subjects were 223 patients with ACD, diagnosed according to the clinical practice guidelines for allergic conjunctival diseases in 28 medical facilities in Japan. The ACD patients were divided into the following five groups: 84 patients with seasonal allergic conjunctivitis (SAC), 52 patients with perennial allergic conjunctivitis (PAC), 41 patients with atopic keratoconjunctivitis (AKC), 38 patients with vernal keratoconjunctivitis (VKC) and 8 patients with giant papillary conjunctivitis (GPC). All cases were examined for clinical ACD, subjective symptoms, objective findings by the clinical score and by a total tear IgE test. An eosinophil examination by conjunctival smear was also performed in 87 ACD patients. RESULTS: The most prevalent subjective symptoms were itching (81.6%) and hyperemia (77.6%). The clinical scores of the objective findings in the patients with SAC, PAC, AKC, VKC and GPC were 16.3 +/- 3.8 (mean +/- SD) points, 16.2 +/- 2.8, 19.8 +/- 6.5, 23.1 +/- 5.3, and 21.4 +/- 3.9, respectively. In the total tear IgE test 72.2% of the ACD patients were positive; i.e., the ratios were 61.9% in SAC, 65.4% in PAC, 80.5% in AKC, 94.7% in VKC, and 75.0% in GPC. In the examination of eosinophils in the 87 ACD patients, 42.5% (37 eyes) were positive, i.e., the ratio was 20.0% in SAC, 36.8% in PAC, 53.3% in AKC, 75.0% in VKC and 33.3% in GPC. The rate of agreement between the total tear IgE test and the examination of eosinophils was kappa = 0.28 (Cohen kappa coefficient). CONCLUSION: Because of the high positive ratio in patients quasi-definitively diagnosed with ACD, we conclude that the total tear IgE test is useful as an auxiliary method for diagnosing ACD.

[A quality of life questionnaire for Japanese allergic conjunctival disease].

PURPOSE: To establish a specific quality of life (QOL) questionnaire for Japanese allergic conjunctival disease (ACD) (Japanese allergic conjunctival disease QOL questionnaire: JACQLQ). SUBJECTS AND METHODS: A multicenter study was conducted in 521 patients with ACD and 127 healthy volunteers (total 648 cases). The JACQLQ ver. 0 was developed by modifying the Japanese rhino-conjunctivitis QOL questionnaire (JRQLQ). The participants were asked to complete the questionnaire, and objective scores were determined by an ophthalmologist using a slit lamp. To confirm validity, item and factor analyses were conducted and correlation coefficients were calculated. RESULTS: The items were grouped into four subscales (Daily activity, Psychological well-being, Eye symptoms, Nasal symptoms) after factor analysis. The JACQLQ had good item-internal consistency (Cronbach's alpha: 0.846-0.934). QOL scores were correlated with eye itching, eye irritation and tearing. Objective scores were correlated with eye redness, eye itching and eye irritation. Face scores were correlated with eye itching, eye irritation and eye redness. CONCLUSION: The JACQLQ is a useful tool for assessing disease specific QOL in ACD.

Japanese guideline for allergic conjunctival diseases.

The definition, classification, pathogenesis, test methods, clinical findings, criteria for diagnosis, and therapies of allergic conjunctival disease are summarized based on the Guidelines for Clinical Management of Allergic Conjunctival Disease (Second Edition) revised in 2010. Allergic conjunctival disease is defined as "a conjunctival inflammatory disease associated with a Type I allergy accompanied by some subjective or objective symptoms." Allergic conjunctival disease is classified into allergic conjunctivitis, atopic keratoconjunctivitis, vernal keratoconjunctivitis, and giant papillary conjunctivitis. Representative subjective symptoms include ocular itching, hyperemia, and lacrimation, whereas objective symptoms include conjunctival hyperemia, swelling, folliculosis, and papillae. Patients with vernal keratoconjunctivitis, which is characterized by conjunctival proliferative changes called giant papilla accompanied by varying extents of corneal lesion, such as corneal erosion and shield ulcer, complain of foreign body sensation, ocular pain, and photophobia. In the diagnosis of allergic conjunctival diseases, it is required that type I allergic diathesis is present, along with subjective and objective symptoms accompanying allergic inflammation. The diagnosis is ensured by proving a type I allergic reaction in the conjunctiva. Given that the first-line drug for the treatment of allergic conjunctival disease is an antiallergic eye drop, a steroid eye drop will be selected in accordance with the severity. In the treatment of vernal keratoconjunctivitis, an immunosuppressive eye drop will be concomitantly used with the above mentioned drugs.

[A prospective, observational, all-prescribed-patients study of cyclosporine 0.1% ophthalmic solution in the treatment of vernal keratoconjunctivitis].

PURPOSE: To evaluate the effectiveness and safety of topical cyclosporine 0.1% in patients with vernal keratoconjunctivitis (VKC). METHODS: All patients who were prescribed topical cyclosporine 0.1% during the 2 year period after market launch were registered and followed up for 6 months. We assessed the severity of 6 subjective ocular symptoms, such as itching and 10 objective signs, such as giant papillae in the tarsal conjunctiva. RESULTS: All scores for symptoms and signs in 2597 patients with VKC significantly decreased throughout a 6-month follow-up. For total symptoms scores, mean changes from baseline at 1, 3, and 6 months were -4.0, -4.8, and -5.1, respectively. Total sign scores were -4.6, -6.1, and -6.5, respectively. Thirty percent of topical steroid users were able to discontinue the steroids within 3 months. Adverse drug reactions (ADRs) were found in 7.44% of patients, the most common ADR being eye irritation. Ocular infections were observed in 1.44% of patients. During long-term use of topical cyclosporine 0.1%, there was no increase in the incidence of ADR and no late-onset ADRs. CONCLUSIONS: Topical cyclosporine 0.1% is an effective and safe treatment for VKC over the long term, provided care is exercised to avoid the occurrence of infection.

Long-Term Safety and Effectiveness of Diquafosol for the Treatment of Dry Eye in a Real-World Setting: A Prospective Observational Study.

INTRODUCTION: Diquafosol is a P2Y2 receptor agonist that has been shown to be effective in the treatment of dry eye disease (DED) in short-term studies; however, its long-term safety and effectiveness have not been evaluated in a real-world setting. METHODS: This prospective, multicentre, open-label observational study was conducted in patients with DED over 12 months. Safety endpoints included the incidence of adverse drug reactions (ADRs) and serious ADRs. Effectiveness endpoints included change from baseline in keratoconjunctival staining score, tear film break-up time (BUT) and Dry Eye-related Quality of Life Score (DEQS). RESULTS: A total of 580 patients were included, most of whom were female (82.9%). The proportion of patients who completed 12 months of observation was 55.0%, the most common reason for discontinuation was patient decision (54.6%). The incidence of ADRs was 10.7% and was highest during the first month of treatment (5.5%); no serious ADRs were reported. Compared with baseline, significant improvements in all effectiveness outcomes, including keratoconjunctival fluorescein staining score, BUT and DEQS summary score, were observed at each evaluation during the treatment period (p < 0.001). CONCLUSION: The present, real-world study showed that diquafosol 3.0% ophthalmic solution was well tolerated and effective in the long-term treatment of DED.

Reduced steroid-induced intraocular pressure elevation in tacrolimus-treated refractory allergic ocular diseases.

PURPOSE: To determine whether topical tacrolimus can lessen steroid-induced intraocular pressure (IOP) elevation. STUDY DESIGN: Open cohort post hoc analysis study. METHODS: Five hundred eleven patients with vernal keratoconjunctivitis or atopic keratoconjunctivitis (mean age 17.0 ± 9.2 years) were studied. All 511 patients were treated with topical tacrolimus with or without topical steroids, and the changes in IOP were measured monthly for 3 months. The elevation in IOP induced by use of topical steroids was calculated using mixed linear regression analyses. The relationship between the elevation in IOP within 4 weeks and the use or nonuse of tacrolimus reported in published data was analyzed using metaregression analysis to estimate the effects of tacrolimus on the IOP in eyes treated with topical steroids. RESULTS: The mean topical steroid-induced IOP elevation in tacrolimus-treated eyes was lower, by 5.2 mmHg (P = 0.04), than that in earlier published data without tacrolimus as the control. In the tacrolimus-treated eyes, the mean betamethasone-induced IOP elevation was 1.3 mmHg without discontinuation of the steroid. Metaregression analysis indicated that glaucoma history and younger age had significant effects on topical steroid-induced IOP elevation, by 4.0 mmHg (P = 0.002) and 3.9 mmHg (P = 0.01), respectively. In tacrolimus-treated eyes, the most significant effect on the IOP was associated with glaucoma history or medication; however, its effect on the IOP was limited to 1.7 mmHg elevation (P = 0.006). CONCLUSIONS: Topical tacrolimus may lessen the steroid-induced elevation in IOP in younger individuals and may be a good adjunctive therapy to avoid IOP elevation in refractory cases.
