雷诺现象
  • 文章类型: Journal Article
    背景:系统性硬化症(SSc)是一种罕见的具有异质性表现的慢性自身免疫性疾病。在过去的十年里,已经进行了几项临床试验来评估SSc的新治疗方案.这项工作的目的是根据可用于SSc药理学管理的新证据更新巴西风湿病学会的建议。
    方法:系统综述,包括根据患者/人群阐述的预定义问题的随机临床试验(RCT),干预,比较,和结果(PICO)战略进行。可用证据的评级是根据建议评估的等级进行的,开发和评估(等级)方法。成为一个推荐,至少需要75%的投票小组同意。
    结果:阐述了关于雷诺现象的药物治疗的六项建议,治疗(愈合)和预防数字溃疡,皮肤受累,根据RCT的结果,SSc患者的间质性肺病(ILD)和胃肠道受累。新药,如利妥昔单抗,作为皮肤受累的治疗选择,利妥昔单抗,托珠单抗和尼达尼布被纳入ILD的治疗方案.根据投票小组的专家意见,详细阐述了硬皮病肾危象和肌肉骨骼受累的药物治疗建议,因为没有发现安慰剂对照的随机对照试验。
    结论:本指南根据文献证据和专家意见更新并纳入新的SSc治疗方案。为临床实践决策提供支持。
    BACKGROUND: Systemic sclerosis (SSc) is a rare chronic autoimmune disease with heterogeneous manifestations. In the last decade, several clinical trials have been conducted to evaluate new treatment options for SSc. The purpose of this work is to update the recommendations of the Brazilian Society of Rheumatology in light of the new evidence available for the pharmacological management of SSc.
    METHODS: A systematic review including randomized clinical trials (RCTs) for predefined questions that were elaborated according to the Patient/Population, Intervention, Comparison, and Outcomes (PICO) strategy was conducted. The rating of the available evidence was performed according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. To become a recommendation, at least 75% agreement of the voting panel was needed.
    RESULTS: Six recommendations were elaborated regarding the pharmacological treatment of Raynaud\'s phenomenon, the treatment (healing) and prevention of digital ulcers, skin involvement, interstitial lung disease (ILD) and gastrointestinal involvement in SSc patients based on results available from RCTs. New drugs, such as rituximab, were included as therapeutic options for skin involvement, and rituximab, tocilizumab and nintedanib were included as therapeutic options for ILD. Recommendations for the pharmacological treatment of scleroderma renal crisis and musculoskeletal involvement were elaborated based on the expert opinion of the voting panel, as no placebo-controlled RCTs were found.
    CONCLUSIONS: These guidelines updated and incorporated new treatment options for the management of SSc based on evidence from the literature and expert opinion regarding SSc, providing support for decision-making in clinical practice.

    Nailfold capillaroscopy (NFC) is a reproducible, simple, low-cost, and safe imaging technique used for morphological analysis of nail bed capillaries. It is considered to be extremely useful for the investigation of Raynaud\'s phenomenon and for the early diagnosis of systemic sclerosis (SSc). The capillaroscopic pattern typically associated with SSc, scleroderma (\"SD\") pattern, is characterized by dilated capillaries, microhemorrhages, avascular areas and/or capillary loss, and distortion of the capillary architecture. The aim of these recommendations is to provide orientation regarding the relevance of NFC, and to establish a consensus on the indications, nomenclature, the interpretation of NFC findings and the technical equipments that should be used. These recommendations were formulated based on a systematic literature review of studies included in the database MEDLINE (PubMed) without any time restriction.

    BACKGROUND: Systemic sclerosis (SSc) is an autoimmune chronic disease characterized by vascular impairment, immune dysfunction and collagen deposition. Raynaud\'s phenomenon (RP) and digital ulcers (DU) are prominent features of SSc. Intravenous (IV) iloprost (ILO), according to the recently updated EULAR recommendations, is indicated for RP after failure of oral therapy. Moreover, IV ILO could be useful in DU healing. IV ILO is currently available mainly on the European market approved for RP secondary to SSc with 3-5 days infusion cycle. Unfortunately, data published varies regarding regimen (dosage, duration and frequency). Up to now, ILO has been studied in small cohorts of patients and in few randomized controlled trials.
    METHODS: A systematic review of studies on IV ILO in patients with SSc complicated by DU and RP was performed. Insufficient data were available to perform a meta-analysis according to the GRADE system. We performed a three-stage internet-based Delphi consensus exercise.
    RESULTS: Three major indications were identified for IV ILO usage in SSc: RP non-responsive to oral therapy, DU healing, and DU prevention. IV ILO should be administered between 0.5 and 2.0ng/kg/min according to patient tolerability with a frequency depending on the indication.
    CONCLUSIONS: Although these suggestions are supported by this expert group to be used in clinical setting, it will be necessary to formally validate the present suggestions in future clinical trials.

    OBJECTIVE: Digital vasculopathy (comprising RP, digital ulceration and critical digital ischaemia) is responsible for much of the pain and disability experienced by patients with SSc. However, there is a limited evidence base to guide clinicians in the management of SSc-related digital vasculopathy. Our aim was to produce recommendations that would be helpful for clinicians, especially for those managing patients outside specialist centres.
    METHODS: The UK Scleroderma Study Group set up several working groups to develop a number of consensus best practice pathways for the management of SSc-specific complications, including digital vasculopathy.
    RESULTS: This overview presents the background and best practice consensus pathways for SSc-related RP, digital ulceration and critical ischaemia. Examples of drug therapies, including doses, are suggested in order to inform prescribing practice.
    CONCLUSIONS: A number of treatment algorithms are provided that are intended to provide the clinician with accessible reference tools for use in daily management.
