Project Summary In the 21st century, adenoviral conjunctivitis (Ad-Cs) continues to be an eye infection of epidemic potential that can cause marked symptomatology, work-flow stoppages and significant economic losses. There is no FDA approved treatment for adenoviral conjunctivitis. A treatment that reduces the 5-12 day period of transmission and/or infection even by a few days would have significant public health and economic impact. “Reducing Adenoviral Patient-Infected Days” (RAPID), is a double-masked, randomized planning study of the efficacy of an in-office administration of 5% povidone iodine (PVP-I) compared to artificial tears to reduce duration and severity of Ad-Cs. Data collected at each visit include patient self-reported symptoms, clinical signs and conjunctival swab taken for adenoviral qPCR, IL-8, 16S amplicon sequencing. Of the 212 participants who were successfully screened, 56 tested positive for adenovirus by immunoassay and were randomized to receive either 5% PVP-I or artificial tears. Post-randomization visit completion rates at 1-2 days, 4, 7, 14 and 21 days were 88%, 75%, 79%, 63% and 68% respectively. The Data and Safety Monitoring Committee reviewed final results September 18, 2019 and recommended analysis/publication of several secondary analyses. Cross-sectional data for participants presenting with “pink eye” and longitudinal data for randomized participants provide an unprecedented opportunity to examine relationships between phenotypic data, 16S amplicon sequencing, qPCR and IL-8 (Aim A). Screening data from patient self-report and clinical signs provide strong evidence that a multivariate clinical prediction model could be developed to improve diagnostic accuracy of Ad-Cs in primary care practices where most patients with “pink eye” seek treatment (Aim B). All data reside in secure, de-identified datasets at the Washington University in St. Louis Coordinating Center ready for secondary analyses. This R-21 Secondary Analysis grant will support analysis, submission and publication of manuscripts from these 2 broad Aims within the 24 month funding period.

项目摘要 在21世纪，腺病毒结膜炎(Ad-Cs)仍是眼部感染的流行 可能会导致明显的症状、工作流程中断和显著 经济损失。目前还没有FDA批准的对腺病毒结膜炎的治疗方法。一种治疗 这将减少5-12天的传播和/或感染时间，即使是几天也会 对公共卫生和经济有重大影响。 《减少腺病毒患者感染天数》(RAPID)，是一个双掩蔽、随机的 办公室注射5%聚维酮碘(PVP-I)疗效的计划研究 与人工泪液相比，可减少Ad-Cs的持续时间和严重程度。在每个站点收集的数据 访视内容包括患者自述症状、临床体征和结膜拭子检查。 腺病毒定量聚合酶链式反应、白介素8、16S扩增序列测定。在212名参与者中， 成功筛查，56例腺病毒免疫检测呈阳性，并被随机 接受5%PVP-I或人工泪液。随机化后的访问完成率为1-2 第4、7、14、21天分别为88%、75%、79%、63%、68%。 数据和安全监测委员会审查了2019年9月18日的最终结果，并 建议的分析/出版几个二次分析。的横截面数据 为随机参与者提供“粉红眼”和纵向数据的参与者提供 一个前所未有的机会来研究表型数据、16S扩增子之间的关系 测序、定量聚合酶链式反应和白介素8(目标A)。从患者自我报告和临床体征中筛选数据 提供了强有力的证据，表明多变量临床预测模型可以开发成 在初级保健实践中提高Ad-Cs的诊断准确性，在这些实践中，大多数“粉红色”患者 眼睛“寻求治疗(目标B)。所有数据都驻留在华盛顿的安全的、未识别的数据集中 圣路易斯大学协调中心准备进行二次分析。这所R-21中学 分析补助金将支持分析、提交和出版这两个项目的手稿 广泛的目标是在24个月的资助期内。
