Current interpretation of nailfold capillaroscopy is largely based on qualitative and subjective parameters. These parameters make the accurate assessment of the extent of the nailfold microangiopathy difficult. The authors present a comprehensive method in which several quantitative or semiquantitative parameters are used to assess the main microangiopathic features, such as microhemorrhage, plexus visibility, devascularization, and morphologic anomalies of the end row loops. The method is checked for reproducibility and applied to a sample of 800 healthy people to establish the normal range. The influences of extrinsic variables, such as gender, ethnicity, age, and local nailfold conditions are also included.
目前对甲襞毛细血管镜检查的解读很大程度上基于定性和主观参数。这些参数使得准确评估甲襞微血管病变的程度变得困难。作者提出了一种综合方法，其中使用了几个定量或半定量参数来评估主要的微血管病变特征，如微出血、血管丛可见性、血管减少以及末排襻的形态异常。该方法经过了重复性检验，并应用于800名健康人的样本以确定正常范围。还纳入了外在变量的影响，如性别、种族、年龄和局部甲襞状况。
