Abstract

BACKGROUND:Neuromyelitis optica spectrum disorder (NMOSD) is a rare demyelinating disease in need of more studies to determine effective treatment regimens. The rarity of the disorder, however, makes large randomized-controlled trials challenging. Validation of the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code for NMO could facilitate the use of large healthcare claims data for future research. We aimed 1) to determine the positive predictive value (PPV) of the ICD-9-CM code for NMO as well as evaluate case-finding algorithms for the identification of patients with NMO/NMOSD and 2) to compare the evaluation of and treatment for pediatric versus adult patients. METHODS:This was a multicenter retrospective cohort study of patients with ≥ 1 ICD-9 code for NMO seen at 3 pediatric and 2 adult United States medical centers from 2001-2016. Using a standardized data entry form, pediatric and adult neurologists and rheumatologists reviewed patients' medical records to determine whether patients fulfilled the 2006 criteria for NMO and/or the 2015 criteria for NMOSD in order to determine the positive predictive value (PPV) for the ICD-9-CM code. Demographic and clinical information was abstracted from patient medical records to ascertain variables then evaluated in case-based finding algorithms for further identification of patients with true NMO/NMOSD. We also evaluated differences in clinical characteristics between pediatric and adult patients using chi-squared or Fisher's exact tests, as appropriate, to assess for treatment variation. RESULTS:A single code for NMO had a PPV of 47% across all sites, with significant site variation (0-77%). The best case-finding algorithm included at least 5 codes as well as a documented hospitalization (PPV = =90% for children and PPV = 92% for adults). Children were more likely to be evaluated by a rheumatologist or ophthalmologist, undergo magnetic resonance imaging of the orbits, and receive immunosuppressive and biologic agents than their adult counterparts. Rituximab was administered similarly among the two groups. CONCLUSION:The ICD-9 code for neuromyelitis optica (NMO) is inaccurate for identification of NMO/NMOSD. Using case-finding algorithms increases the PPV. The initial diagnostic evaluation and treatment of NMOSD differs significantly between children and adults.

摘要

背景: 视神经脊髓炎谱系障碍 (NMOSD) 是一种罕见的脱髓鞘疾病,需要更多的研究来确定有效的治疗方案。然而,该疾病的罕见性使得大型随机对照试验具有挑战性。NMO的国际疾病分类,第九次修订,临床修改 (ICD-9-CM) 代码的验证可以促进将大型医疗保健索赔数据用于未来的研究。我们的目的是1) 确定NMO ICD-9-CM代码的阳性预测值 (PPV),并评估用于识别NMO/NMOSD患者的病例发现算法,2) 比较儿科患者与成人患者的评估和治疗。 方法: 这是一项多中心回顾性队列研究,纳入了2001-2016期间在3个儿科和2个美国成人医疗中心就诊的NMO编码 ≥ 1 ICD-9的患者。使用标准化的数据录入表,儿科和成人神经科和风湿病学家审查了患者的医疗记录,以确定患者是否符合NMO的2006标准和/或NMOSD的2015标准,从而确定ICD-9-CM代码的阳性预测值 (PPV)。从患者病历中提取人口统计学和临床信息,以确定变量,然后在基于病例的查找算法中进行评估,以进一步识别具有真实NMO/NMOSD的患者。我们还使用卡方检验或Fisher精确检验 (视情况而定) 评估儿童和成人患者的临床特征差异,以评估治疗差异。 结果: NMO的单个代码在所有位点具有47% 的PPV,具有显著的位点变异 (0-77%)。最佳病例查找算法包括至少5个编码以及记录的住院 (儿童PPV = 90%,成人PPV = 92%)。儿童更可能由风湿病专家或眼科医生进行评估,接受眼眶磁共振成像,并接受免疫抑制剂和生物制剂。利妥昔单抗在两组中给药相似。 结论: 视神经脊髓炎 (NMO) 的ICD-9编码对NMO/NMOSD的鉴别不准确。使用病例发现算法增加PPV。NMOSD的初始诊断评估和治疗在儿童和成人之间显著不同。

METHODS::Purpose: To report on ocular Vogt-Koyanagi-Harada (VKH)-like syndrome under vemurafenib treatment for metastatic melanoma.Design: A case report.Method: Description of clinical and imaging manifestations including fundus photography, fluorescein, and indocyanine green angiography.Results: A 46-year-old Thai female was diagnosed with metastatic melanoma of the skin and had been treated with multiple surgical excisions, radiotherapy, and vemurafenib (initial dose 480 mg orally twice daily, subsequently increased to maximum dose of 960 mg twice daily). After 6 months of vemurafenib use, she complained of bilateral redness and photophobia and was diagnosed with bilateral anterior uveitis, which was topically treated. Two weeks later, her visual acuity (VA) sharply deteriorated to 20/80 and counting fingers. Ocular examination at that stage stronly resembled acute VKH disease. She exhibited intraocular inflammation, and her fundus examination revealed bilateral optic disc swelling and serous retinal detachment. Fluorescein angiogram showed disc leakage and multiple pinpoint hyperfluorescence leakage spots and indocyanine green demonstrated multiple hypofluorescent spots. Oral prednisolone 30 mg/day was commenced while vemurafenib medication was ceased. Three weeks later, her vision improved, and serous retinal detachment subsided. However, her cutaneous melanoma recurred.Conclusions: Vemurafenib, a potential adjunct treatment for metastatic melanoma, was complicated by the development of panuveitis, papillitis, and multiple serous detachments. These ocular symptoms were similar to the presentation of acute VKH syndrome.

METHODS::Comprehensive reviews of the clinical characteristics and pathogenesis of Aicardi-Goutières syndrome (AGS), particularly its contextualization within a putative type I interferonopathy framework, already exist. However, recent reports of attempts at treatment suggest that an assessment of the field from a therapeutic perspective is warranted at this time. Here, we briefly summarize the neurological phenotypes associated with mutations in the seven genes so far associated with AGS, rehearse current knowledge of the pathology as it relates to possible treatment approaches, critically appraise the potential utility of therapies, and discuss the challenges in assessing clinical efficacy. WHAT THIS PAPER ADDS: Progress in understanding AGS disease pathogenesis has led to the first attempts at targeted treatment. Further rational therapies are expected to become available in the short- to medium-term.

METHODS::Purpose: To report the efficacy of adalimumab in a case of chronic Vogt-Koyanagi-Harada (VKH) disease refractory to conventional corticosteroids and immunosuppressive therapy and complicated by central serous chorioretinopathy (CSC).Case report: A 66-year-old woman diagnosed with VKH was treated with intravenous corticosteroids followed by oral corticosteroids and cyclosporine. However, systemic corticosteroids could not be tapered because of recurrent ocular inflammation and systemic complications (diabetes mellitus, moon face, bone weakness), while CSC appeared in both eyes. A diagnosis of chronic VKH resistant to medications complicated by corticosteroid-induced CSC was made. Systemic corticosteroids and cyclosporine were tapered and adalimumab initiated. Bilateral ocular inflammation and CSC were gradually reduced and visual acuity improved without any adverse effect. Twelve months after starting adalimumab monotherapy, no signs of active VKH and CSC were present.Conclusions: Adalimumab is one of the effective therapeutic options for refractory VKH disease complicated with corticosteroid-induced adverse effects.
