title: [Renal function and histologic findings in immunoglobulin A nephropathy].
abstract: We investigated 28 patients with IgA nephropathy. Discriminatory analysis was the method used to determine discriminatory power of certain clinical and pathohistological parameters. Semiquantitatively were determined pathohistological parameters: glomerular index in range 0-10, vascular index 1-4, interstitial fibrosis 0-10, interstitial infiltration 0-3, tubular atrophy 0-3. Nephrotic syndrome (symbolic value), quantitative proteinuria and creatinine clearance at the time of biopsy and year after (continual variable) were used as clinical parameters. Discriminatory power was determined as a degree of decreasing Shennon's entropy by distinction of patients according to value of creatinine clearance at the time of biopsy, and a year after biopsy. Discriminatory power was measured in he information measurement units (bit). Based on discriminatory-predictive analysis we determined that glomerula changes and interstitial fibrosis had an equal effect (discriminatory power) on renal function at the time of biopsy and a year latter, as well as predictive value of these histological parameters and creatinine clearance at the time of biopsy.
