BACKGROUND: The anti-neutrophil cytoplasmic antibody-associated (ANCA) vasculitides includes granulomatosis with polyangiitis (Wegener's) (GPW), Chrug-Strauss syndrome (CSS) and microscopic polyangiitis (MPA). Since it has low incidence in our field, there are a few published papers. The aim of this study was to report the clinical characteristics, activity and damage of these vasculitides in Mexico City's metropolitan eastern area. METHODS: We studied 28 cases with ANCA-associated vasculitis in the aforementioned area. The classification was made according to the ACR 1990 criteria, the Chapel Hill 2012 consensus, and the EULAR 2007 recommendations. We collected demographic data, as well as data of clinical manifestations, laboratory, management and outcomes. The activity was established using the Birmingham Vasculitis Activity Score (BVAS) and the damage using the Vasculitis Damage Index (VDI). We used paired t test and 95% confidence intervals (95% CI). RESULTS: 15 females and 13 males were included, 20 with GPW and 8 with CCS. The mean age was 50.1 ± 12.7 years, and the evolution time was 69 ± 49.6 months. We didn't find cases of MAP. 23 patients (82.1%) had general symptoms. The initial and final BVAS means were 10.5 and 1.5 (p < 0.001) and the global VDI was 2.4. CONCLUSIONS: The presence of ANCA-associated vasculitides is rare in the eastern Metropolitan area of Mexico City. GPW was predominant over CCS, and MPA was absent. They are multi-system vasculitides with high scores of initial activity and moderate damage.
