“…Thus, de spite the general concept that renal involvement with H U V has been relatively benign, careful observation is required as in the case o f SLE . Sixteen patients (18 cases) had histologically proven glomerular involvement [2,4,[5][6][7][8][9][10][11][12][13], O f the various histopathologic types reported from 1973 to 1990, mesangial proliferative glomerulonephritis has been most frequently found, whereas membranous type was found only in 2 cases [8,13]. With regard to the therapy and prognosis o f renal involvement, prednisolone plus cyclo phosphamide or azathioprine lowered serum creatinine level [5,7,11] but did not improve serum complement [11], In contrast, a case associated with severe proliferative glomer ulonephritis was refractory to 70 mg prednisolone every other day and progressed to end-stage renal function which required hemodialysis [12].…”
