Abstract
Vernal keratoconjunctivitis (VKC) is a chronic, bilateral corneal and conjunctival problem which typically presents in young individuals. VKC is characterized by itching, photophobia, white mucous discharge, lacrimation, foreign body sensation, and pain due to corneal involvement of shield ulcers. Vernal keratoconjunctivitis is categorized within ocular diseases. The diagnosis is clinical, as no sure biomarkers pathognomonic of the disease have yet been identified. The VKC therapy relies on different types of drugs, from antihistamines and topical steroids to cyclosporine or tacrolimus eye drops. In extremely rare cases, there is also the need for surgical treatment for the debridement of ulcers, as well as for advanced glaucoma and cataracts, caused by excessive prolonged use of steroid eye drops. We performed a systematic review of the literature, according to PRISMA guideline recommendations. We searched the PubMed database from January 2016 to June 2023. Search terms were Vernal, Vernal keratoconjunctivitis, and VKC. We initially identified 211 articles. After the screening process, 168 studies were eligible according to our criteria and were included in the review. In this study, we performed a systematic literature review to provide a comprehensive overview of currently available diagnostic methods, management of VKC, and its treatments.

Clinical Outcomes of Topical 0.1% Ciclosporin Cationic Emulsion Used on Label in Children with Vernal Keratoconjunctivitis. Ophthalmol Ther 2023; 12:1787-1793. [PMID: 37043141 PMCID: PMC10164196 DOI: 10.1007/s40123-023-00707-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 03/22/2023] [Indexed: 04/13/2023] Open
Abstract
INTRODUCTION The purpose of this short article is to report the clinical outcomes of topical 0.1% ciclosporin cationic emulsion (CsA-CE) used on label in children with vernal keratoconjunctivitis (VKC). METHODS In this prospective, non-comparative, observational study children affected by active severe VKC were treated for at least 12 months with topical 0.1% CsA-CE. The drug was instilled in both eyes 4 times daily. Data collected from medical charts for the baseline visit (T0) and 1-year follow-up visit (T1) included symptomatic score (0-15), clinical score (0-15), side effects, rescue therapy (need and total number of courses with 0.1% dexamethasone 4 times daily for 5 days), ocular complications and tolerability (visual analog scale [0-100]). RESULTS Data from 25 children (20 boys, 5 girls; mean [± standard deviation] age 8.40 ± 2.54 years) were included in the study. Of the 25 patients, 23 (92%) used 0.1% CsA-CE eye drops as per label recommendations, including four patients who had prematurely stopped using topical galenic CsA due to side effects. Symptomatic and clinical scores decreased significantly after treatment, with the mean symptomatic score decreasing from 9.76 ± 1.27 at T0 to 3.80 ± 1.08 at T1, and the mean clinical score decreasing from 9.20 ± 1.32 at T0 to 3.44 ± 1.00 at T1; both P < 0.0001). Five patients (20%) required at least one course of rescue medication (mean 3.4 ± 4.8 courses/year). No patients experienced ocular complications during the study, and treatment tolerability was very high (mean score 89.40 ± 5.46). CONCLUSION Our findings confirm that topical CsA-CE is an effective on-label option for children with VKC in the real-life setting. In our pediatric patient population, CsA-CE provided good clinical outcomes with a limited need for rescue medication, and it was well tolerated by almost all patients, including those who were intolerant to galenic formulations.

Abstract
Vernal keratoconjunctivitis (VKC) is a form of ocular allergy primarily affecting children. Considered a rare disease in Europe, its prevalence varies by geographic region and is poorly studied in the United Kingdom. There is considerable national variation in the management of VKC within the United Kingdom, risking misdiagnosis and delays to treatment for some children. This can significantly impact their quality of life, with the potential for lasting negative consequences. Based on discussions between experienced clinicians from six large centers across the United Kingdom, this article describes best practice recommendations for United Kingdom settings, including principles for diagnosis, referral, initial and long-term management, and supportive care. Recommendations include guidance on referral timing, which should depend on VKC severity, and a stepwise approach to treatment. Joint management by primary care and secondary care is recommended and the importance of supportive care, including emotional support and outreach to schools, is highlighted. Because frequent flareups are common in VKC, it is essential that families have access to the information they need to manage the disease and routes to access rapid care if needed. A thorough understanding of the nature of VKC, its triggers, and how best to manage it, by both patients and their families, is critical to ensuring appropriate management and to improving patient outcomes.

Abstract
INTRODUCTION Vernal keratoconjunctivitis (VKC) is an inflammatory condition in children that can cause severe eye complications. Treatment is based on corticosteroid therapy during flare-ups, then antihistamines and cyclosporine in calmer periods. The dosage and posology of cyclosporine are subject to debate. METHODS The aim of the study is to compare the evolution in symptomatic and clinical scores, and need for topical corticosteroid treatment in a population of children with severe VKC treated with two dosages of cyclosporine treatment (0.1% and 2%). Data were compiled on inclusion then every three months from March, with a total follow-up duration of 12 months. Data concerning patient evolutions and complications were collected for the two treatment groups. RESULTS The mean age of the 46 children was 8.8 ±2.4 years with age at onset of symptoms of 5.1 ± 0.9 years. The cohort was predominantly (65%) male. Corticosteroid dependence on inclusion was present in 52% of the children included. A significant improvement in the various symptomatic and clinical scores was observed following treatment with cyclosporine (0.1% and 2%). Use of topical corticosteroid treatment reduced from 19 drops per month on inclusion to 4 drops per month at 12 months. Safety was comparable for the two groups. CONCLUSION Treatments with cyclosporine 0.1% and 2% lead to a favourable evolution in clinical and symptomatic scores and reduced corticosteroid use. Cyclosporine 0.1% is an interesting alternative to the 2% dosage, particularly due to its availability and ease of handling.

Abstract
Vernal keratoconjunctivitis (VKC) is a complex and chronic, multifactorial Th2 cell-mediated chronic ocular surface inflammatory condition that typically affects predominantly male children in hot or warm climates. The primary symptom is intense ocular pruritus, often significant enough to affect activities of daily living. Clinical features differ from simple forms of allergic conjunctivitis in that they are more-or-less confined to the superior tarsus and limbus. There is also a risk of corneal involvement, which leads to irreversible vision loss in approximately 6% of patients. Right now, there is no standardized treatment protocol, and many of the currently available options are not effective in severe and recurrent cases. As such, it is imperative to understand this complex allergic immune response in order to identify future therapeutic targets. This review will focus on potential drug targets in VKC, with particular emphasis on immunomodulators and immunobiologic agents.

Abstract
Vernal keratoconjunctivitis (VKC) and atopic keratoconjunctivitis (AKC) are potentially severe and complex disease in its management among the various allergic eye diseases. In this regard, studies clarified the etiopathogenetic mechanisms. The workup should be multidisciplinary. The treatment includes topical and systemic medications with anti-inflammatory and immunosuppressant activity. However, a definition of nationally- and internationally-shared diagnostic protocols would also be needed and validated access to therapeutic options of proven safety and efficacy to avoid the use of galenic preparations, up to now still essential in the management of moderate-severe VKC. Finally, recognizing VKC and AKC, among rare diseases, at a national and international level would be an essential step to allow the management of VKC with adequate timings and settings within the National Health System.

Abstract
BACKGROUND Vernal keratoconjunctivitis (VKC) is a severe type of allergic conjunctivitis for which treatment strategies are still under debate. OBJECTIVES This study sought to conduct a systematic review and meta-analysis to evaluate the efficacy of medical treatments for VKC. METHODS The PubMed, Cochrane Library, Embase, and ScienceDirect databases were searched to assess the efficacy of treatments for VKC. Random-effect meta-analyses on changes in clinical scores of symptoms and signs between baseline and after treatment, stratified on treatment classes, were computed. Meta-regressions were searched for potential influencing parameters. RESULTS Included were 45 studies (27 randomized controlled trials and 18 prospective cohort studies), 1749 patients (78% were men; mean age, 11.2 years), and 12 different treatment classes. Mast cell stabilizers (MCSs; usually considered as first-line therapy), cyclosporine, and tacrolimus were the most studied drugs (in three-quarters of studies). Overall, all clinical scores improved. Total symptom and sign score decreased for MCSs (effect size, -3.19; 95% CI, -4.26 to -2.13), cyclosporine (effect size, -2.06; 95% CI, -2.72 to -1.40), and tacrolimus (effect size, -2.39; 95% CI, -3.36 to -1.43). No significant differences were shown depending on treatment classes, concentration, age, sex, baseline activity scores, and atopy. Sensitivity analyses demonstrated similar results. CONCLUSIONS This study confirms the efficacy of MCSs in the treatment of VKC. Efficacy of cyclosporine and tacrolimus did not differ, suggesting that tacrolimus is a good alternative to cyclosporine for severe cases of VKC. Further studies are needed to compare other drugs and their precise place in treatment strategy.

Abstract
Allergic conjunctivitis is a disease of increasing prevalence that affects both children and adults and causes significant deterioration of their quality of life and sometimes irreversible visual damage. There are various forms of the disease, some are allergen-induced such as seasonal and perennial allergic conjunctivitis, giant papillary conjunctivitis, and contact allergic blepharoconjunctivitis, whereas others are not always explained by allergen exposure, such as vernal keratoconjunctivitis and atopic keratoconjunctivitis. We review their clinical course, characteristics, and differential diagnosis, and highlight recent advances in their pathophysiology and treatment.

Abstract
In this study, a sensitive quantitative method based on high performance liquid chromatography combined with high-resolution mass spectrometry, Q ExactiveTM-Orbitrap® was set up and applied for the determination of the immunosuppressor agents cyclosporine A and tacrolimus in novel ethanol-free ophthalmic formulations for the treatment of Vernal keratoconjunctivitis. Different storage parameters in terms of storage temperatures and practical usage conditions were investigated to assess the stability of all formulations during shelf life simulating the real conditions as well to confirm the feasibility of use of ethanol-free products. The methodology was linear (r2 = 0.995) over the concentration range 0–200 ng/mL, and its selectivity, precision, accuracy and recovery were all within the required limits. Under different conditions (storage period 0–90 days, 5–25 °C, unopened/usage simulated conditions), our results revealed that both active pharmaceutical ingredients (API) show satisfactory stability up to 30 days of storage/usage, with a significant and consistent concentration decline of cyclosporine A after this time point when its hydroalcoholic formulation was kept at 25 °C.

Abstract
Vernal keratoconjunctivitis is a chronic inflammatory disease of the ocular surface and one of the worst types of allergic conjunctival diseases. Because of its chronic nature, it can damage the cornea, resulting in sight-threatening complications if left untreated. The disease affects mainly young children starting around the age of 7 years. We used keywords to search for published English articles in PUBMED, Google Scholar, EMBASE, and Cochrane Database of Systematic Reviews. Most of the published literature is focusing on general management of the disease and few publications focusing on treatment in the pediatric age group. We highlight the importance of how is the topical management differs between age groups. We focused on the importance of doing cycloplegic refraction for each child as the risk of keratoconus and oblique astigmatism is high in these cases. Furthermore, we highlight the importance of using eye lubricants as a therapeutic and preventive tool for the attacks of the disease. We highlight that most of the recent effective medications (especially the off-label ones) are not available in Saudi Arabia, such as tacrolimus, and some are only available to be prepared in tertiary center pharmacies as Cyclosporine A with higher concentrations.

Abstract
Vernal keratoconjunctivitis (VKC) is a rare, recurrent and multifactorial ocular disease, which typically flares up during spring and affects especially male children and adolescents. This condition does not usually respond to common treatments with antihistamines or mast cells stabilizers, whereas corticosteroids have effective results. Corticosteroids need to be carefully administered, to avoid adverse effects, mainly the secondary development of glaucoma, cataracts, or infections. Immunosuppressive agents, such as cyclosporin (CyA) or tacrolimus are, therefore, frequently employed in VKC patients. Only the 0.1% CyA (1 mg/mL) concentration has an approved and specific clinical indication for the treatment of VKC and this drug was given the denomination of orphan drug by the European Commission (EU/3/06/360) in 2006. So far, few studies have been conducted to evaluate the efficacy and the side effects of topical 0.1% CyA. Different topical CyA concentrations, ranging from 0.05% to 2%, and various types of formulation are available at the moment. In the future, 0.1% CyA will presumably take an important part in the management of VKC. The present review focuses on eye drops containing 0.1% CyA; however, more studies will be needed to define its long-term efficacy in the natural course of this severe ocular disease.

Abstract
BACKGROUND Vernal keratoconjunctivitis (VKC) is a common eye disease and can result in permanent decrease or loss of vision. Houttuynia eye drops (HED) is used for the treatment of VKC. However, the clinical evidence of HED has not been well concluded. Herein, we described a proposed systemic review and meta-analysis to evaluate the clinical efficacy of HED for the treatment of VKC. METHODS Six electronic databases (Medline, Embase, the Cochrane database, Chinese National Knowledge Infrastructure, Wanfang database, and Chinese Biology and Medicine database) will be searched for randomized controlled trials (RCTs) which evaluating the clinical efficacy of HED for the treatment of VKC. Studies meet the eligibility criteria will be included. Data of the included studies will be extracted and the quality will also be evaluated. Data synthesis will be performed using RevMan software. Sensitivity analysis and publication bias will also be investigated. RESULTS This study will provide high-quality systemic review and synthesis of RCTs on efficacy of HED for the treatment of VKC. CONCLUSION This systemic review and meta-analysis will conclude the efficacy of HED for the treatment of VKC. REGISTRATION PROSPERO CRD42019124737.

Abstract
INTRODUCTION Vernal keratoconjunctivitis (VKC) is a severe disease with a prevalence of < 1 case out of 10,000 in Europe, which occurs mainly in pediatric age and is characterized by a severe and often bilateral chronic inflammation of the ocular surface. The diagnosis is generally confirmed by the finding at the ocular examination of conjunctival hyperemia, papillary hypertrophy in the tarsal conjunctiva, giant papillae, papillae in the limbus region. OBJECTIVE Aim of this review is to provide an updated overview on the disease focused on clinical grading system, searching papers published in the last decade on VKC in scientific databases. RESULTS Currently there are no standardized criteria for diagnosis of VKC and there is no uniformity to define disease severity, which makes difficult to diagnose and treat the disease. CONCLUSIONS Given the wide overlap of the symptoms of VKC with the allergic conjunctivitis, criteria of probable, possible or improbable diagnosis are needed, providing pediatricians with parameters useful for deciding whether to drive the patient to the ophthalmologist for diagnostic confirmation.

Abstract
The aim of this study was to evaluate whether the control of ocular symptoms with cyclosporine or with tacrolimus in eye drops allows to improve sun exposure and therefore serum level of vitamin D (VD; 25OHD), in the more severe forms of vernal keratoconjunctivitis (VKC). Out of 242 children followed for active VKC, 94 were treated with 1% cyclosporine or 0.1% tacrolimus eye drops, while the other 148 with mild VKC did not need to be treated with immunomodulators. VD serum levels were measured in spring and autumn in 71 children. In total, 60 of them were treated with cyclosporine eye drops (first group) and 11 (not responding to cyclosporine therapy previously) with 0.1% tacrolimus eye drops (second group) between March and November 2016. Pre-treatment median values of VD were 23.7 ng/mL in the first group and 23.8 in the second group, and post-treatment values increased up to 32.8 and 32.9 ng/mL, respectively. Before treatment, 33% presented a deficiency (25OHD < 20 ng/mL), and at the end of summer, only 4% were deficient. The overweight children had lower improvement in VD serum levels than children with a body mass index (BMI) lower than 85th percentile. Children in therapy with cyclosporine, but requiring the administration of local steroid therapy during the summer for control of the symptoms, showed a greater improvement in 25OHD serum levels in ng/mL (23-37 ng/mL) than children who did not require steroid therapy (24-35 ng/mL). Furthermore, there was a significant difference in change of 25OHD in children presenting limbal VKC (21-41 ng/mL) versus tarsal VKC (24-35 ng/mL) ( P = 0.04). Our study suggests that ocular treatment carried out with immunomodulator eye drops could allow for an improvement in 25OHD serum levels. In children with active VKC and at risk of 25OHD deficiency, likely due to avoidance of sun exposure, the role of other risk factors (BMI, phototype and treatment) on 25OHD serum levels should be considered.
