Report of the Croatian registry of native kidney biopsies for year 2019

This report describes data collected by the Croatian Registry of Renal Biopsies (CRRB) for the year 2019. Patients and methods: nine centers (82%) provided data for 255 native kidney biopsies. We assessed the anthropometric data, data on serum creatinine concentration (sCr), 24 h proteinuria, haematuria, serum albumin level, arterial hypertension, histological diagnosis, and complications after renal biopsy. Results: examined group consisted of 58% males, median age 58 y (18-80 y) and 42% women, median age 57 y (20- 86 y). Males had a more impaired renal function at the time of renal biopsy, nephrotic syndrome, and hypertension. The most prevalent clinical presentation were urinary abnormalities (34.9%). Among all biopsy cases, primary glomerular diseases were the most often found histology group (41.5%), and IgA nephropathy was the most frequent diagnosis(47.1%). Among secondary glomerular diseases, pauci-immune glomerulonephritis (PIGN) was most often found (30.9%). The highest proteinuria was observed in minimal change disease and diabetic nephropathy (DN). The highest sCR values were found in membranoproliferative glomerulonephritis (MPGN) and necrotizing vasculitis. Patients with MPGN and DN had the highest blood pressure levels. Conclusion: CRRB provides important data on the epidemiology of biopsy-proven kidney diseases from the whole territory of Croatia.
