Introduction

Glomerulonephritis represents a significant cause of chronic kidney disease, with renal biopsy playing a fundamental role in its diagnosis. In Brazil, comprehensive and systematized data remain limited, and previous reports commonly identify Focal Segmental Glomerulosclerosis (FSGS) as the most frequent glomerulopathy.

Methods

This was a descriptive study conducted at Santa Casa de Porto Alegre between 2021 and 2023, including adult patients who underwent kidney biopsy with a histological diagnosis of glomerulonephritis. Clinical, laboratory, and histological data of the included patients were analyzed.

Results

A total of 366 patients were included. Over the study period, a 21% increase in the number of biopsies performed was observed. The main indication for biopsy was nephrotic syndrome, followed by non-nephrotic proteinuria, with or without hematuria. IgA nephropathy was the most prevalent glomerulopathy (20%), followed by FSGS and lupus nephritis.

Conclusion

Previous studies have reported an increasing prevalence of IgA nephropathy in Brazil.This single-center study from the Southeast of Brazil confirms a higher prevalence of IgA nephropathy as the most common glomerulopathy which may be partially explained by a shift in biopsy indications—particularly an increase in biopsies performed outside the context of nephrotic syndrome, such as those prompted by non-nephrotic range proteinuria
