Popis: | Superimposition of poststreptococcal glomerulonephritis (PSGN) on the course of IgA nephropathy (IgAN) is uncommon. A case of PSGN during IgA nephropathy is presented. A 30-year-old man who had alternating gross and microscopic hematuria for 7 months underwent a renal biopsy. The first renal biopsy revealed IgAN with mesangial deposits of IgA and C3. Two months later, the patient suffered generalized edema, proteinuria, hematuria, an increased ASO titer and a decreased C3 level. A second renal biopsy revealed diffuse endocapillary proliferative glomerulonephritis with epimembranous hump-like electron-dense deposits of C3, but the original mesangial IgA deposits had disappeared. A diagnosis of acute PSGN was indicated. Two months after the onset of acute nephritic syndrome, the patient remained asymptomatic, except for microscopic hematuria and proteinuria. Some cases with persistent proteinuria or hematuria after PSGN are probably related to preexisting IgAN. |
