RESUMEN
Context: Fibrosis is universally accepted as a poor prognostic finding in renal pathology. Semi-quantitative assessment is widely used for prognostication in pathology. Aims: We propose a semi-quantitative method to prognosticate primary nonproliferative glomerular diseases. Settings and Design: A semi-quantitative method based on Banff schema, 97 classification has been modified to suit the requirements. Glomerular, tubulointerstitial, and vascular compartments were scored independently, and the scores were totaled to obtain total scores. Materials and Methods: Seventy-six renal biopsies were assessed by semi-quantitative scores and the individual compartmental and total scores were correlated with serum creatinine levels. Follow-up was available in 24 cases. Statistical Analysis: Pearson correlation coefficient, two-tailed t test, to determine the P value. Results: P values were significant for the total scores as well as individual compartments. There is a linear correlation between the scores and serum creatinine levels. A total score of ≥5 was significant. Conclusions: The semi-quantitative scoring system based on modified Banff schema, 1997 is useful in prognosticating renal biopsies in primary nonproliferative glomerular diseases.
