ABSTRACT

Nail fold is one of the most accessible sites for studying changes in the microcirculation in various microangiopathies. The characterization of changes in microvasculature can provide useful clues towards the diagnosis and prognosis of a disease. The diagnostic utility of nail fold capillaroscopy has improved and expanded over the past couple of decades. Beyond connective tissue diseases, it is now explored for its role in various systemic and dermatological diseases. Incorporation of nail-fold capillaroscopy in the diagnostic criteria of systemic sclerosis has generated interest among dermatologists. The current review is aimed at providing knowledge about nail-fold capillaroscopy to dermatologists. For the purpose of review, a PubMed search was done using the keywords “nail fold capillaries” and “nail fold capillaroscopy”. All the articles were retrieved and classified into reviews and clinical studies of various types. The final data were then analyzed and presented in a narrative fashion.

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.
