    Abstract:
    The clinicopathologic correlation of 18 cases of idiopathic nephrotic syndrome (INS) with diffuse mesangial proliferation (MP), (over 3 cells per intercapillary space) showed clinical characteristics similar to INS with minimal glomerular lesions (MGL) in relation to age at onset, sex, period of evolution, intensity of proteinuria, hypercholesterolemia, hypoalbuminemia and edema. However, there was a greater incidence of cases with arterial hypertension, hematuria, azotemic retention and positive glomerular immunofluorescence. Out of the 18 cases, 10 were corticosensitive (group I) and 8 were corticoresistant (group II). Patients of I followed a similar course as those with MGL, while most cases of group II showed proteinuria through observation periods up to 5 years. No differences were found in the initial clinical presentation between these 2 groups. The only item with prognostic value was the intensity of the mesangial proliferation which in group I was of 3 to 5 cells per intercapillary space, while in group II, in the spaces of some glomeruli, there were up to 10 mesangial cells present. These findings suggest the convenience to practice renal biopsy before initiating treatment in children with INS and arterial hypertension, hematuria and/or azotemic retention in order to identify this group of patients that appears to be different from that with MGL.
