Background: The present study aimed to investigate the Nailfold Capillaroscopy (NC) features of the patients with dermatomyositis (DM) and its correlation with their disease activity indices, physical findings, and laboratory results.

Methods: The present cross-sectional study was conducted on 27 DM patients above 16 years old who had referred to an(there are 3 clinics not one) outpatient rheumatology clinics from 2012 to 2013. Nailfold capillaroscopy and calculation of disease activity indices were performed separately for all the patients by two rheumatologists who were blinded to each other's results. Statistical analyses were performed using chi-square and Mann-Whitney U tests.

Results: The mean age of the patients was 39.2±14.1 years with the mean disease duration of 13.1±15.2 months (range: 1-72 months). Myopathic electromyography (EMG) findings showed a strong association with scleroderma pattern (p=0.015). However, disease activity in each organ system and global disease activity showed no significant association between scleroderma pattern and other NC findings. (Disease activity in each organ system and also global disease activity were both assessed to see if they are associated with scleroderma pattern and other NC findings so if we use between it means we are looking for an association between scleroderma pattern and other NC findings and this is not what we have done and is wrong.)

Conclusion: This study revealed no significant relationship between disease activity indices and NC features. Thus, it may be more precise to interpret the results of NC in conjunction with other physical and laboratory findings.
