摘要

弹性假性黄瘤(PXE)是一种罕见的遗传性代谢性疾病,其特征是皮肤、视网膜和血管壁弹性纤维的营养不良钙化。心脏受累的数据不一致。因此,我们旨在评估PXE患者对增量心肺运动试验(CPET)的心肺反应。共有30名PXE患者(54.0±11.2岁,男性40.0%)和15名匹配的对照组接受了症状有限的增量CPET治疗。PXE的患者提供了一个受损的工作率峰值相比控制(84.2±16.0%和94.7±10.4%,p = 0.03),是伴随着较低的峰值耗氧量(%预测和mL / min /公斤),减少每增加耗氧量的增加工作效率(ΔV´O2 /ΔWR, 8.4±3.0毫升/分钟/ W和11.3±4.9毫升/分钟/ W, p = 0.02),低氧脉冲峰值(78.0±12.3%和90.6±19.6%,p = 0.01),减少每分通气量在高峰锻炼(V´E, 66.2±82.9±16.8%比25.2%,p = 0.02)。总而言之,我们目前观察到主要的心脏循环参数受损,而没有检测到实质性的通气限制。这一发现对PXE管理的潜在影响值得进一步研究。

Pseudoxanthoma elasticum is associated with cardiocirculatory inefficiency.

Pseudoxanthoma elasticum (PXE) is a rare, genetic, metabolic disease characterized by dystrophic calcification of elastic fibres in the skin, retina and vascular wall. Data on cardiac involvement are inconsistent. Hence, we aimed to evaluate cardiorespiratory response to incremental cardiopulmonary exercise testing (CPET) in PXE. A total of 30 PXE patients (54.0 ± 11.2 years, 40.0% male) and 15 matched controls underwent symptom-limited incremental CPET. PXE patients presented an impaired peak work rate as compared to controls (84.2 ± 16.0% vs. 94.7 ± 10.4%, p = 0.03) that was accompanied by a lower peak oxygen uptake (in % predicted and mL/min/kg), reduced increments in oxygen uptake per increments of work rate (ΔV´O2/ΔWR, 8.4 ± 3.0 mL/min/W vs. 11.3 ± 4.9 mL/ min/W, p = 0.02), lower peak oxygen pulse (78.0 ± 12.3% vs. 90.6 ± 19.6%, p = 0.01) and reduced minute ventilation at peak exercise (V´E, 66.2 ± 16.8% vs. 82.9 ± 25.2%, p = 0.02). To summarize, we presently observed impairment in mainly cardiocirculatory parameters, whilst no substantial ventilatory limitation was detected. The potential implications of this finding for PXE management warrant further study.
