Arthritis Research Therapy 2011 13 302 http content 13 1 302 LETTER Response to Comparison of laser Doppler imaging fingertip lacticemy test and nailfold capillaroscopy for assessment of digital microcirculation in systemic sclerosis - authors reply Marcelo JU Correa Luis EC Andrade and Cristiane Kayser See related letter by Sulli etal. http content 13 1 301 and related research by Correa etal. http content 12 4 R157 We thank Sulli and colleagues 1 for their interest in our article entitled Comparison of laser Doppler imaging fingertip lacticemy test and nailfold capillaroscopy for assessment of digital microcirculation in systemic sclerosis 2 which was published in a recent issue of Arthritis Research Therapy. Sulli and colleagues commented on our results regarding the lack of correlation between the laser Doppler imaging LDI technique and nailfold capillaroscopy NFC and raised interesting questions. We totally agree with the comment that NFC is a powerful tool for the assessment of microvascular damage in systemic sclerosis SSc . Recently we showed a positive correlation between NFC abnormalities and the extent of cutaneous and visceral involvement in SSc patients confirming that NFC is a relevant approach not only for diagnosis but also for the evaluation of the extension and severity of SSc 3 . However NFC evaluates only the morphological aspect of SSc vasculopathy and complementary tools are used with different results in many studies for the evaluation of functional aspects of peripheral vascular disease 4 . Sulli and colleagues mentioned three interesting recently published papers 5-7 with results different from those of our paper. However different methods for the evaluation of blood perfusion were used in each of them and it is difficult to compare results obtained with different techniques. Cutolo and colleagues 5 assessed fingertip blood perfusion by laser Doppler .
