脑下垂体 amenorrhea患者表现出增加的choriocapillaris血管密度,这表明早期的微血管适应低雌激素主义. 光学连贯断层扫描血管学揭示了这些变化,影响了视网膜循环.
科学领域:
- 眼科医生 眼科 眼科
- 内分泌学 在内分泌学.
- 血管生物学 血管生物学
背景情况:
- 脑下垂体 amenorrhea (HA) 是一种由于脑下垂体功能障碍而缺乏月经的情况.
- 与HA相关的眼部微血管变化尚未得到充分理解.
- 光学连贯断层扫描血管造影 (OCTA) 允许对视网膜和胆道血管进行非侵入性评估.
研究的目的:
- 评估HA患者视网膜和胆囊细胞循环的变化.
- 调查眼部微血管变化与HA中的系统参数之间的关系.
主要方法:
- 一项前性,横截面的观察性研究,涉及25名HA患者和25名年龄相匹配的健康对照.
- 用OCTA测量了表面毛细血管 (SCP),深毛细血管 (DCP) 和胆毛细血管中的血管密度 (VD).
- 在HA组中收集了包括BMI,激素水平 (FSH,LH,prolactin),胰岛素和皮质醇在内的系统参数.
主要成果:
- 在HA患者和对照人群之间没有观察到SCP和DCP血管密度的显著差异.
- 在整个图像区域 (p=0.038 RE,p=0.044 LE) 中,在HA患者中发现了较高的胆角毛囊体内疾病的趋势 (p=0.038 RE,p=0.044 LE).
- 与对照组相比,HA女性的FOVALCHORIOCAPILLARIS VD显著更高 (p=0.005LE).与对照组相比,HA女性的FOVALCHORIOCAPILLARIS VD显著更高.
- 发现了骨SCP/DCP VD和子宫内膜厚度之间的相关性,以及骨SCP/整个区域SCP VD和皮质醇/FSH水平之间的相关性.
结论:
- 在HA患者中,OCTA检测到胆囊层的变化,其特点是静脉动脉疾病增加.
- 这一发现表明,胆管囊中的微血管"紧缩"可能代表了HA中对低雌激素的早期适应性反应.
- 这项研究强调了与HA相关的视网膜中潜在的早期血管变化.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
