Abstract

Systemic sclerosis (scleroderma) leads to morbidity and mortality through a combination of inflammation, fibrosis and vascular damage leading to internal organ complications affecting the heart, lung, kidneys and bowel. More than half of those diagnosed ultimately die from the disease. Current treatments focus on broad spectrum immunosuppression or organ-based therapy for complication such as lung fibrosis, pulmonary or systemic hypertension. Targeting peptide mediators such as endothelin-1 have already led to licensed effective therapies for SSc vasculopathy. Outcomes are improving but as well as providing a major clinical challenge there are great opportunities for research translation that can be expected to improve understanding of the pathogenesis of SSc and also develop better and more targeted therapy. Key pathways and mediators can be identified within the skin and blood vessels and these are now being examined in early stage clinical trials. Promising results are emerging from targeting cytokine signalling, including IL-6, and from other immune-inflammatory therapies including lipid mediators such as LPA1. Other approaches to modulate TGFbeta and other profibrotic pathways also have potential although safety and toxicity remain to be determined. Since many profibrotic pathways have important physiological roles the assessment of safety and toxicity will be paramount. Nevertheless, advances in understanding the interplay between different pathological processes and progress in clinical trial design and patients stratification mean that targeted therapies are emerging and likely to be further developed and refined to have application in other important clinical contexts such as lung fibrosis.

摘要

系统性硬化症(硬皮病)通过炎症、纤维化和血管损伤的综合作用导致发病和死亡,进而引发影响心脏、肺、肾脏和肠道的内脏器官并发症。超过半数的确诊患者最终死于该病。目前的治疗方法主要集中在广谱免疫抑制或针对诸如肺纤维化、肺动脉高压或系统性高血压等并发症的器官靶向治疗。靶向内皮素-1等肽类介质已经带来了针对系统性硬化症血管病变的获批有效疗法。尽管治疗效果正在改善,但这不仅带来了重大的临床挑战,也为研究转化提供了巨大机遇,有望增进对系统性硬化症发病机制的理解,并开发出更好、更具针对性的治疗方法。关键信号通路和介质可在皮肤和血管中得以识别,目前正在早期临床试验中对其进行研究。针对细胞因子信号传导(包括白细胞介素-6)以及包括溶血磷脂酸1等脂质介质在内的其他免疫炎症疗法已取得了有前景的结果。调节转化生长因子β和其他促纤维化信号通路的其他方法也具有潜力,尽管安全性和毒性仍有待确定。鉴于许多促纤维化信号通路具有重要的生理作用,安全性和毒性评估将至关重要。然而,对不同病理过程之间相互作用的理解取得进展,以及临床试验设计和患者分层方面的进步,意味着靶向治疗正在出现,并可能会进一步发展和完善,以应用于其他重要的临床情况,如肺纤维化。
