Vasculitis & polymyalgia rheumatica
Nailfold videocapillaroscopy abnormalities and vascular manifestations in Behçet's syndrome
Authors' conclusion
The presence of ≥2 qualitative abnormalities in NVC is associated with Vasculo-Behçet.
Study context
- Population
- Patients with Behçet's syndrome (BS), 52.3% men, 84.6% European Caucasian; vascular involvement in 24 (36.9%)
- Participants
- 65 patients
- Outcome
- Microcirculation abnormalities on nailfold videocapillaroscopy (NVC) and their clinical association, especially with vascular manifestations
Main finding
As reported in the abstract
Qualitative NVC abnormalities
- Any qualitative nailfold videocapillaroscopy (NVC) abnormality
- 47.7%
- Tortuous and branched capillaries
- 21.5%
- Microhaemorrhage
- 12.3%
- Enlarged capillary
- 7.7%
- Giant capillary
- 3.1%
- ≥2 qualitative NVC abnormalities associated with vascular involvement
- p=0.031
- ≥2 qualitative NVC abnormalities associated with venous thrombotic events
- p=0.024
- ≥2 qualitative NVC abnormalities associated with superficial thrombophlebitis (ST)
- p=0.003
- Tortuous and branched capillaries associated with previous superficial thrombophlebitis (ST)
- p=0.025
Observational data: associations, not effects.
Further findings
NVC vs Raynaud's phenomenon and ANA
- Positive ANA: more frequent non-specific capillaroscopic abnormalities
- P = 0.003
- No association between NVC and RP or ANA
