The rapid progressive glomerulonephritis is an emergency case. Renal function is rapidly lost within weeks or a few months (rarely within days) due to necrotizing extracapillary proliferative crescentic glomerulonephritis. Early diagnosis and treatment improve prognosis, as the best prognostic marker is creatinine when treatment is initiated. Read More

Background: Nephritis is the most important chronic complication of IgA Vasculitis (IgAV)/Henoch-Schönlein purpura (IGAV/HSP) and thus the main prognostic factor of this most common childhood vasculitis. Since the prognosis and treatment selection depends on the mode of interpretation of biopsy material, in this manuscript we have presented several issues related to the uneven application of different histological classifications in IgAV/Henoch-Schönlein purpura nephritis (HSPN). The nephritis of IgAV/IGAV/HSP will be abbreviated as HSPN for this paper. Read More
