随着移植技术逐年发展,异基因造血干细胞移植患者的生存期延长,长期并发症成为影响患者预后及生活质量的主要原因。眼移植物抗宿主病是异基因造血干细胞移植术后最常见的眼部并发症,发生率可高达50%以上。根据发病时间可分为急性及慢性眼移植物抗宿主病,临床上最常以慢性炎症及眼表组织纤维化为特点,主要表现为干眼和不同程度的角结膜炎,治疗较为棘手,可不同程度影响患者视觉质量及生活质量,严重可致盲。近年来眼移植物抗宿主病越来越受到国内外学者重视,其发病机制、临床特点、诊断及治疗相关研究逐渐深入,文章针对眼移植物抗宿主病的临床诊疗新进展进行综述。总体而言,眼移植物抗宿主病早期识别仍较为困难,早期诊断策略有待进一步探索。目前治疗对眼移植物抗宿主病的效果较为有限,或缺乏充足的循证医学证据,临床上缺乏针对不同严重程度及疾病活动度的分级诊疗策略,未来有待进一步探索新的治疗靶点及疾病活动监测指标,将有助于改善患者长期预后及生活质量。
Despite advancements in allogeneic hematopoietic stem cell transplantation techniques leading to improved overall survival rates, long-term complications have emerged as the primary contributors to poor prognosis and diminished quality of life. Ocular graft-versus-host disease (oGVHD), a prevalent complication affecting over 50% of patients post-transplantation, frequently manifests as refractory dry eye, often accompanied by keratoconjunctivitis. Patients with oGVHD routinely suffer from visual impairment and a decline in their quality of life.Currently, research into the mechanisms, clinical features, diagnosis, and treatment of oGVHD has progressively deepened. This article reviews the latest advancements in the clinical diagnosis and management of oGVHD. Notably, there is a pressing need for strategies focused on early diagnosis and treatment, as early recognition of oGVHD remains challenging. Existing treatments for oGVHD either exhibit limited efficacy or lack robust clinical evidence to support their use as the best available options.Further research is imperative to develop tiered diagnostic and treatment approaches, including the exploration of novel therapeutic targets and biomarkers for disease detection. Such endeavors hold the promise of enhancing patients' long-term prognosis and quality of life.
干眼是以泪膜稳态丢失及伴随眼部不适症状为特征的最常见眼表疾病,泪膜不稳定、泪液高渗透性、眼表炎症及感觉神经异常为其主要病因。地夸磷索钠是一种P2Y2受体激动剂,能刺激黏蛋白及泪液分泌,其独特的作用机制为干眼的治疗开辟了新的方向,本文就地夸磷索钠近年的临床及基础研究进展作一综述。
Dry eye is one of the most common ocular surface diseases. It is characterized by a loss of homeostasis of the tear film, and accompanied by ocular symptoms, in which tear film instability and tear hyperosmolarity, ocular surface inflammation, and neurosensory abnormalities play major etiological roles. Diquafosol tetrasodium is a purinergic P2Y2 receptor agonist that promotes mucin and aqueous tear secretion. The unique pharmacological mechanism of diquafosol tetrasodium opens up a new direction for the medical therapies of dry eye. This article reviews the clinical therapeutic effect and research progress of diquafosol tetrasodium for the past few years.
