Abstract

Introduction: With the life expectancy of patients with cystinosis increasing (ORPHA213), the corneal burden and the objective assessment of corneal crystal deposition have become increasingly important. Previous research highlights the disadvantages of hospital-prepared cysteamine solutions (HPCS), including limited efficacy, which can lead to visual decline. Cystadrops® is a viscous topical treatment in cystinosis care that counteracts these disadvantages.

Methods: A total of 14 patients with cystinosis and corneal involvement are being followed in the multidisciplinary cystinosis clinic of the University Hospital of Leuven. Data retrieved between September 2014 and March 2023 were analyzed. All patients were initially treated with HPCS before switching to Cystadrops®. Patients were assessed yearly according to the standard clinical ophthalmological examination for patients with cystinosis developed by Pinxten et al. Photophobia, corneal crystal deposition, and corneal crystal deposition depth were measured by the Liang cystinosis photophobia score, Gahl score, and anterior segment optical coherence tomography (OCT) respectively. Corneal densitometry was assessed with Scheimpflug imaging.

Results: OCT mean crystal depth was 83% of total corneal thickness. The mean corneal density was 28.9 grayscale units. We found a positive trend (F = 0.20, p = 0.65) in corneal densitometry despite the use of HPCS, with a decreasing trend (F = 3.30, p = 0.08) after switching to Cystadrops®. Photophobia scores significantly reduced after switching treatments (p = 0.008). In total, seven patients developed anterior segment complications while using HPCS. No new anterior segment complications developed while using Cystadrops®.

Conclusions: This study underscores previous research, demonstrating HPCS' limited effectiveness in reducing corneal crystal deposition due to unachievable dosing frequencies and poor stability. Our data highlights the effectiveness of Cystadrops® in treating the ocular symptoms of cystinosis. The data demonstrates the difficulty of reversing high levels of corneal crystal deposition and anterior segment complications. Starting Cystadrops® early in the disease course may prevent high rates of crystal deposition, thus reducing complications and their impact on vision and quality of life.

在比利时队列中使用粘性半胱胺滴眼液:早期3年结果
随着胱氨酸病患者预期寿命的增加(ORPHA213),角膜负担和角膜晶体沉积的客观评估变得越来越重要。先前的研究强调了医院配制的半胱胺溶液(HPCS)的缺点,包括效果有限,可能导致视力下降。Cystadrops®是一种用于胱氨酸病护理的粘性局部治疗,可以抵消这些缺点。方法:在鲁汶大学医院的多学科胱氨酸病门诊对14例胱氨酸病合并角膜受累患者进行随访。对2014年9月至2023年3月期间检索的数据进行分析。所有患者在切换到Cystadrops®之前最初使用HPCS治疗。根据Pinxten等人对胱氨酸病患者的标准临床眼科检查,每年对患者进行评估。分别采用Liang胱氨酸病畏光评分、Gahl评分和前段光学相干断层扫描(OCT)测量角膜的畏光程度、角膜晶体沉积和角膜晶体沉积深度。采用Scheimpflug显像评估角膜密度。结果:OCT平均晶体深度为角膜总厚度的83%。平均角膜密度为28.9灰度单位。我们发现,尽管使用HPCS,角膜密度测量仍呈阳性趋势(F = 0.20, p = 0.65),但改用Cystadrops®后,角膜密度测量呈下降趋势(F = 3.30, p = 0.08)。转换治疗后畏光评分显著降低(p = 0.008)。总共有7例患者在使用HPCS时出现了前段并发症。使用Cystadrops®时未出现新的前段并发症。结论:本研究强调了先前的研究,表明HPCS在减少角膜晶体沉积方面的有效性有限,因为其剂量频率难以达到,稳定性差。我们的数据强调了Cystadrops®在治疗胱氨酸病眼部症状方面的有效性。数据表明,扭转高水平的角膜晶体沉积和前段并发症的难度。在疾病早期开始使用Cystadrops®可以防止高晶体沉积率,从而减少并发症及其对视力和生活质量的影响。

期刊介绍: Aims and Scope Ophthalmology and Therapy is an international, open access, peer-reviewed (single-blind), and rapid publication journal. The scope of the journal is broad and will consider all scientifically sound research from preclinical, clinical (all phases), observational, real-world, and health outcomes research around the use of ophthalmological therapies, devices, and surgical techniques. The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/series, trial protocols and short communications such as commentaries and editorials. Ophthalmology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. Rapid Publication The journal’s publication timelines aim for a rapid peer review of 2 weeks. If an article is accepted it will be published 3–4 weeks from acceptance. The rapid timelines are achieved through the combination of a dedicated in-house editorial team, who manage article workflow, and an extensive Editorial and Advisory Board who assist with peer review. This allows the journal to support the rapid dissemination of research, whilst still providing robust peer review. Combined with the journal’s open access model this allows for the rapid, efficient communication of the latest research and reviews, fostering the advancement of ophthalmic therapies. Open Access All articles published by Ophthalmology and Therapy are open access. Personal Service The journal’s dedicated in-house editorial team offer a personal “concierge service” meaning authors will always have an editorial contact able to update them on the status of their manuscript. The editorial team check all manuscripts to ensure that articles conform to the most recent COPE, GPP and ICMJE publishing guidelines. This supports the publication of ethically sound and transparent research. Digital Features and Plain Language Summaries Ophthalmology and Therapy offers a range of additional features designed to increase the visibility, readership and educational value of the journal’s content. Each article is accompanied by key summary points, giving a time-efficient overview of the content to a wide readership. Articles may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand the scientific content and overall implications of the article. The journal also provides the option to include various types of digital features including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations. All additional features are peer reviewed to the same high standard as the article itself. If you consider that your paper would benefit from the inclusion of a digital feature, please let us know. Our editorial team are able to create high-quality slide decks and infographics in-house, and video abstracts through our partner Research Square, and would be happy to assist in any way we can. For further information about digital features, please contact the journal editor (see ‘Contact the Journal’ for email address), and see the ‘Guidelines for digital features and plain language summaries’ document under ‘Submission guidelines’. For examples of digital features please visit our showcase page https://springerhealthcare.com/expertise/publishing-digital-features/ Publication Fees Upon acceptance of an article, authors will be required to pay the mandatory Rapid Service Fee of €5250/$6000/£4300. The journal will consider fee discounts and waivers for developing countries and this is decided on a case by case basis. Peer Review Process Upon submission, manuscripts are assessed by the editorial team to ensure they fit within the aims and scope of the journal and are also checked for plagiarism. All suitable submissions are then subject to a comprehensive single-blind peer review. Reviewers are selected based on their relevant expertise and publication history in the subject area. The journal has an extensive pool of editorial and advisory board members who have been selected to assist with peer review based on the afore-mentioned criteria. At least two extensive reviews are required to make the editorial decision, with the exception of some article types such as Commentaries, Editorials, and Letters which are generally reviewed by one member of the Editorial Board. Where reviewer recommendations are conflicted, the editorial board will be contacted for further advice and a presiding decision. Manuscripts are then either accepted, rejected or authors are required to make major or minor revisions (both reviewer comments and editorial comments may need to be addressed). Once a revised manuscript is re-submitted, it is assessed along with the responses to reviewer comments and if it has been adequately revised it will be accepted for publication. Accepted manuscripts are then copyedited and typeset by the production team before online publication. Appeals against decisions following peer review are considered on a case-by-case basis and should be sent to the journal editor. Preprints We encourage posting of preprints of primary research manuscripts on preprint servers, authors’ or institutional websites, and open communications between researchers whether on community preprint servers or preprint commenting platforms. Posting of preprints is not considered prior publication and will not jeopardize consideration in our journals. Authors should disclose details of preprint posting during the submission process or at any other point during consideration in one of our journals. Once the manuscript is published, it is the author’s responsibility to ensure that the preprint record is updated with a publication reference, including the DOI and a URL link to the published version of the article on the journal website.
