  • Title: Immune deposits and mesangial hypercellularity in minimal change nephrotic syndrome: clinical relevance.
    Author: Allen WR, Travis LB, Cavallo T, Brouhard BH, Cunningham RJ.
    Journal: J Pediatr; 1982 Feb; 100(2):188-91. PubMed ID: 7057326.
    Abstract:
    Occasional patients with nephrotic syndrome and minimal histologic change demonstrate glomerular deposition of small amounts of immunoglobulin and complement. Some consider this a disease distinct from MCNS. To investigate the clinical importance of immune deposits and mesangial hypercellularity in the initial biopsy, the clinical records, follow-up data, and renal biopsies of 68 patients (ages 6 months to 16 years) with MCNS by light microscopy were reviewed. Among 68 patients followed a mean of 6.2 years, eight of 25 patients with immune deposits on initial renal biopsy were steroid nonresponsive. Only one of 43 patients without immune deposits was steroid nonresponsive (P = 0.00005). Of 44 patients with normal mesangial cellularity, 31 experienced fewer than three relapses a year, whereas of 15 patients with mesangial hypercellularity, only six experienced fewer than three relapses a year (P = 0.035). The data suggest that immune deposits and increased mesangial cellularity in children with NS and minimal light microscopic change may predict the clinical course.
