To assess the utility of nailfold video capillaroscopy (NVC) in patients diagnosed with acute and chronic graft versus host disease (GVHD) of the skin.
Patients diagnosed with acute and chronic skin GVHD (n=11) and those without the diagnosis of GVHD (controls) (n=21) underwent NVC to assess capillary density, morphology, and hemorrhage. Statistical comparisons were made using Fisher's exact test. The study was performed from March 1, 2024, to August 1, 2024.
Patients diagnosed with acute and chronic GVHD were observed to have considerably more microhemorrhages, ramifications, and disorganized capillaries when compared with patients without a diagnosis of acute or chronic GVHD.
This study reveals significant NVC abnormalities in patients with GVHD, suggesting distinct microvascular features that imply potential diagnostic value. The NVC may be a valuable tool for diagnosing and monitoring GVHD and warrants further investigation in larger cohorts.
评估甲襞视频毛细血管镜检查(NVC)在诊断为皮肤急慢性移植物抗宿主病(GVHD)患者中的应用价值。
诊断为急慢性皮肤GVHD的患者(n = 11)和未诊断为GVHD的患者(对照组)(n = 21)接受NVC检查,以评估毛细血管密度、形态和出血情况。采用Fisher精确检验进行统计学比较。该研究于2024年3月1日至2024年8月1日进行。
与未诊断为急慢性GVHD的患者相比,诊断为急慢性GVHD的患者观察到有更多的微出血、分支和毛细血管紊乱。
本研究揭示了GVHD患者存在明显的NVC异常,提示有独特的微血管特征,具有潜在诊断价值。NVC可能是诊断和监测GVHD的有价值工具,值得在更大队列中进一步研究。
