ANCA negative pauci-immune glomerulonephritis with systemic involvement

Abstract: Systemic vasculitides (SV) are a group of diseases with multi system involvement and varied clinical presentation. Anti-neutrophil cytoplasmic antibody (ANCA) testing has high sensitivity and specificity for SV. We describe the clinical course of four patients who had pauci-immune glomerulonephritis with systemic involvement without serological ANCA positivity; they were followed up for a cumulative 55 patient months. The mean Birmingham vasculitis score score was 23. All four had systemic symptoms with arthra… Show more

“…Only a small percentage of ANCA-negative pauce-immune vasulitis present with otolaryngological and pulmonary symptoms (6,10) in contrast to ANCAassociated vasculitis where paranasal sinus and lung involvement are predominant, with a high prevalence of pulmonary haemorrhage (40%) in MPO positive patients (11). The mechanisms leading to the occurrence of ANCA-negative vasculitis are not very clear.…”

“…Большинство исследователей отмечают, что гломе-рулосклероз и интерстициальный фиброз более выраже-ны у АНЦА-негативных пациентов, чем при АНЦА-ассо-циированном ГН [15,25,38,39]. Вместе с тем, в отличие от работы французских исследователей, отметивших сходство воспалительных морфологических изменений О р и г и н а л ь н ы е и с с л е д о в а н и я…”

“…2). Так, в Азии в общей когорте больных рauci-иммунным ГН была выше частота АНЦА-негативных случаев (33-39 и 3-27% соответственно), па-циенты были моложе (35-40 и 55-65 лет соответственно), при биопсии почки чаще выявляли клубочки с полулуния-ми (67-76 и 48-50% соответственно), была выше потреб-ность в ГД (43-68 и 10% соответственно) и наблюдалась склонность к нефротической протеинурии [22,38]. При этом наши данные в целом приближались к европей-ским.…”

“…Pauci-immune crescentic glomerulonephritis (CrGN) is the most common cause of rapidly progressive glomerulonephritis (RPGN) in adults. 1,2 Mostly, CrGN is attributed to systemic small-vessel vasculitis, like granulomatosis with polyangiitis, microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis, but also with renal limited vasculitis in a small number of cases. CrGN and RPGN share a common serologic hallmark, defined by the presence of the anti-neutrophil cytoplasmic antibodies (ANCAs), and for this reason they are known as ANCA-associated vasculitis.…”
