RESUMEN

Long-term observation of patients with ANCA-associated vasculitis (AAV) allows the identification of different longitudinal patterns of ANCA levels during follow-up. This study aimed to characterize these patterns and to determine their prognostic significance. All ANCA determinations performed in two university hospitals during a 2-year period were retrospectively reviewed. Patients were included in the analysis if they had high titers of anti-myeloperoxidase (anti-MPO) or anti-proteinase 3 (anti-PR3) antibodies at least once, ≥ 5 serial ANCA determinations and AAV diagnosed by biopsy or American College of Rheumatology (ACR) classification criteria. Patients' time-course ANCA patterns were classified as monophasic, remitting, recurrent or persistent. Associations between ANCA patterns and prognostic variables (relapse rate and renal outcome) were analysed by univariate and multivariate statistics. A total of 99 patients [55 with microscopic polyangiitis (MPA), 36 with granulomatosis with polyangiitis (GPA) and eight with eosinophilic granulomatosis with polyangiitis (EGPA)] were included. Median follow-up was 9 years. Among patients diagnosed with MPA or GPA, recurrent or persistent ANCA patterns were associated with a higher risk of clinical relapse [hazard ratio (HR) = 3·7, 95% confidence interval (CI) = 1·5-9·1 and HR = 2·9, 95% CI = 1·1-8·0, respectively], independently of clinical diagnosis or ANCA specificity. In patients with anti-MPO antibodies, the recurrent ANCA pattern was associated with worsening renal function [odds ratio (OR) = 5·7, 95% CI = 1·2-26·0]. Recurrent or persistent ANCA patterns are associated with a higher risk of clinical relapse. A recurrent ANCA pattern was associated with worsening renal function in anti-MPO-associated vasculitis.

RESUMEN

El liquen escleroso es una enfermedad inflamatoria crónica mucocutánea que causa una gran molestia en hombres y mujeres de todas las edades. La etiología exacta es desconocida, aunque factores genéticos, autoinmunitarios e infecciosos se han implicado en su patogénesis. El tratamiento de primera línea es la corticoterapia ultrapotente tópica durante un tiempo limitado, y se reserva la cirugía en caso de fimosis, estenosis uretral, sinequias y carcinoma escamoso (AU)


Lichen sclerosus is a chronic inflammatory mucocutaneous disease that is highly bothersome for men and women of all ages. The exact etiology is unknown, although genetic and autoimmune factors, as well as infections, have been implicated in its pathogenesis. First-line treatment is highly potent topical corticosteroid therapy for short periods. Surgery is reserved for cases of phimosis, urethral stenosis, synechiae, and squamous cell carcinoma (AU)
