Abstract:
Objective The aim of the study was to observe the features of nail fold microcirculation in systemic sclerosis (SSc) patients and to compare these findings in SSc patients with patients with other connective tissue diseases.Methods Forty patients with SSc and thirty-seven patients with other connective tissue diseases were included in the study and all the patients reported symptoms of Raynaud's phenomenon in the hands were also included.Nail fold capillaroscopy (NFC) was performed and the abnormality of nail fold microcirculation between the two groups were compared.The relations between nail fold capillaroscopic findings and clinicolaboratory parameters in SSc patients were analyzed.Statistical analysis were carried out by t-test and Chi-square.Results The loss of capillaries and dilated and giant capillaries and hemorrhage as well as neoangiogenesis were hallmarks of the scleroderma capillary findings,which could be detected by nail fold capillaroscopy.The abnormalities of nail fold microcirculation in SSc patients were more severe and more specific than those in other connective tissue disease patients.The total scores of nail fold capillaroscopy test were obviously higher in SSc patients with lung or esophagus involvement than those patients without these organ involvement,meanwhile,the total scores of nail fold capillaroscopic findiugs were elevated in SSc patients with anti-Scl70 antibody than those with negative group.Conclusion The nail fold capillaries of patients with SSc have specific abnormalities,and nail fold capill-aroscopy could distinguish between SSc and other connective tissue diseases,therefore it could be used as a promising tool for early detection of patients who may have the potential to develop scleroderma and it is also helpful in assessing disease severity.
