弹性假黄瘤(PXE)是一种罕见的多系统常染色体隐性结缔组织病。在大多数情况下,PXE 的皮肤表现首先出现,随后出现严重的眼部和心血管并发症。在我们目前的研究中,除了皮肤镜检查之外,我们还引入了新技术、自发荧光 (AF) 和漫反射 (DR) 成像来评估五名 PXE 患者受影响的皮肤部位。大多数皮肤部位受 PXE 影响的皮肤区域在皮肤镜检查中显示出先前观察到的模式。通过新颖的成像,受 PXE 影响的皮肤病变显示出高 AF 强度。在我们的测量过程中,发现与未受影响的皮肤相比,受 PXE 影响的皮肤区域的平均、最小和最大 AF 强度值明显更高。相反,使用 660 和 940 nm 照明获取的图像没有显示出明显的差异。我们的结果表明,AF 成像可用于 PXE 患者皮损严重程度的体内诊断和量化。此外,它还是一种安全、快速且经济有效的诊断方法。 AF 成像还可用于客观监测未来 PXE 可能的新型治疗方法的疗效。
Pseudoxanthoma elasticum (PXE) is a rare multisystemic autosomal recessive connective tissue disease. In most cases, skin manifestations of PXE are the first to develop, followed later by severe ocular and cardiovascular complications. In our present study, in addition to dermoscopy, we introduced novel techniques, autofluorescence (AF) and diffuse reflectance (DR) imaging for the assessment of affected skin sites of five PXE patients. PXE-affected skin areas in most skin sites showed a previously observed pattern upon dermoscopic examination. With the novel imaging, PXE-affected skin lesions displayed high AF intensity. During our measurements, significantly higher mean, minimum and maximum AF intensity values were found in areas of PXE-affected skin when compared to uninvolved skin. Conversely, images acquired with the use of 660 and 940 nm illumination showed no mentionable difference. Our results demonstrate that AF imaging may be used in the in vivo diagnostics and quantification of the severity of the skin lesions of PXE patients. In addition, it is a safe, fast and cost-effective diagnostic method. AF imaging may be also used to objectively monitor the efficacy of the possible novel therapeutic approaches of PXE in the future.
