Vasculitis & polymyalgia rheumatica
Nailfold videocapillaroscopy in antineutrophil cytoplasmic antibody–associated vasculitis
Authors' conclusion
There was no evidence of differences in nailfold capillaroscopy abnormalities between those diagnosed with AAV and the control group.
Study context
- Population
- Patients with a current diagnosis of AAV (median age 59; 52% women; GPA 58%, EGPA 21%, MPA 21%; 82% antineutrophil cytoplasmic antibody (ANCA) positive) and controls
- Participants
- 33 vs 21
- Exposure
- AAV vs controls
- AAVn = 33
- Controlsn = 21reference
- Outcome
- Nailfold videocapillaroscopy abnormalities: capillary density, morphology, dilation, microhemorrhage and disorganization
Methodological detailscontrolled, semiquantitative analysis reviewed by 2 rheumatologists

- Semiquantitative analysis reviewed by 2 rheumatologists
Main finding
As reported in the abstract
Capillary density, dilation, morphology, microhemorrhages and disorganization
- No statistically significant differences between the 2 groups
Observational data: associations, not effects.
