Zusammenfassung:Abstract Nephrologists are familiar with severe cases of anti-neutrophil cytoplasmic antibodies-associated vasculitis (AAV) presenting as rapidly progressive glomerulonephritis. However, less is known about AAV with slowly progressive renal involvement. While its existence is acknowledged in textbooks, much remains unknown regarding its relative frequency versus more aggressive cases as well as about the optimal therapeutic approach and response to therapy. Moreover, this uncommon presentation may be underdiagnosed, given the scarce familiarity of physicians. In this issue of Clinical Kidney Journal, Trivioli et al. report the largest series to date and first systematic assessment of patients with AAV and slowly progressive renal involvement, defined as a reduction in estimated glomerular filtration rate (eGFR) of 25–50% in the 6 months prior to diagnosis after excluding secondary causes. Key findings are that slowly progressive AAV may be less common than previously thought, although it still represents the second most common presentation of renal AAV, it usually has a microscopic polyangiitis, anti-myeloperoxidase, mainly renal phenotype in elderly individuals, diagnosis may be late (over one-third of patients had end-stage kidney disease at diagnosis), clearly identifying an unmet need for physician awareness about this presentation, but those not needing renal replacement therapy at diagnosis still responded to immunosuppression.
