RESUMEN
To evaluate associations between the domains of the ANCA-associated vasculitis patient-reported outcome (AAV-PRO) instrument and clinical variables. Patients with granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (EGPA), or renal-limited vasculitis (RLV) were recruited from a tertiary care center in Mexico City. Demographic, clinical, serological, and treatment-related data were retrieved. Disease activity, damage, patient and physician global assessments (PtGA and PhGA) were evaluated. All patients completed the AAV-PRO questionnaire, male patients also completed the International Index of Erectile Function (IIEF-5) questionnaire. Seventy patients (44 women and 26 men) were included, with a median age of 53.5 years (43-61), and a disease duration of 82 months (34-135). Moderate correlations were identified between the PtGA and the AAV-PRO domains: social and emotional impact, treatment side effects, organ-specific symptoms, and physical function. The PhGA correlated with the PtGA and prednisone doses. Subanalyses of the AAV-PRO domains according to sex, age, and disease duration showed significant differences in the treatment side effects domain, with higher scores in women, in patients < 50 years, and in patients with disease duration < 5 years. The domain of concerns about the future showed a higher score in patients with disease duration < 5 years. A total of 17/24 (70.8%) of men who completed the IIEF-5 questionnaire were classified as having some degree of erectile dysfunction. The domains of AAV-PRO correlated with other outcome measures, while differences were found between some of the domains according to sex, age, and disease duration.

Primary meningococcal septic arthritis (PMSA) is an extremely rare local infection by Neisseria meningitidis in the absence of meningitis or meningococcaemia syndrome. A 30-year-old healthy, immunocompetent man presented with arthralgia, fever, chest rash, and significant swelling of the right knee. On admission, a disseminated maculopapular and purpuric rash, oligoarthritis, neutrophilia, and elevated acute phase reactants were documented. Following arthrocentesis of the right knee, isolation of N. meningitidis and the presence of calcium oxalate crystals in the synovial fluid were reported. The diagnosis of PMSA was made. Histological analysis of the skin lesion showed leucocytoclastic vasculitis. He was treated with intravenous ceftriaxone plus open surgical drainage and ambulatory cefixime with adequate response. After 1 month, he presented resolution of the pathological process. We performed an extensive review of the literature, finding that the key elements supporting the diagnosis of PMSA are prodromal upper respiratory tract symptoms and skin involvement prior to or synchronous with the arthritis. Also, the most frequently involved joint is the knee. This report is the first case of a patient presenting with PMSA associated with calcium oxalate crystals in the synovial fluid. Herein, we discuss the most frequent clinical manifestations, the unusual histological features, the recommended treatment, and the reported prognosis of this rare entity.
