[Necrotizing vasculitis with predominant kidney involvement].

We report five patients with necrotizing vasculitis with predominant renal involvement; the diagnostic and therapeutics was effected completely at regional hospital. We detach: a) the clinical presentation's forms with rapidly progressive renal failure with microscopic hematuria and minimal proteinuria; b) the biopsy of kidney with necrotizing vasculitis or necrotizing glomerulonephritis (microscopic polyarteritis). We review the necrotizing vasculitis with predominant renal involvement in its pathogenic, clinical and histological aspects, and we insist that the diagnostic and early treatment are fundamental for prognostic's improvement of these patients. We conclude that this diagnostic and treatment can be made in regional hospitals with sensible physicians by the theme.
