Abstract
- Introduction Takayasu arteritis (TA) is a large vessel vasculitis characterized by the involvement of the aorta and its branches. In the present study, the nailfold videocapillaroscopy (NVC) findings of the TA patients were evaluated and compared to healthy individuals. Additionally, the association of NVC abnormalities with disease activity and subclavian artery involvement was also investigated. Method In the present study, NVC changes of 15 TA patients and 15 age- and sex-matched healthy controls were compared. The frequency of hypertension, dyslipidemia, and smoking status was not different between the case and control group. Capillary density, avascular area, tortuosity, micro-hemorrhages, and ramification were investigated. Among capillaries' diameters; capillary length and width, arterial and venous limbs diameters were also compared between two groups. Results The capillary length and venous limb diameter were lower in TA patients compared to control cases (P-value: 0.026 and 0.049, respectively). Moreover, TA patients have more tortuous capillaries (P-value: 0.035). Among TA patients; capillary length, width, arterial and venous limbs diameter was lower in hands with subclavian involvement (P-value: 0.014, 0.034, 0.009 and 0.022, respectively). Furthermore, the arterial and venous limbs diameter were lower in TA patients with active disease compared to patients with inactive disease (P-value: 0.018 and 0.049, respectively). Conclusion In the present study, we have shown that the hands with subclavian artery involvement have short, thin and tortuous capillaries which could be secondary to hypoperfusion. To the best of our knowledge, this is the first report describing NVC changes in TA.
