Glomerular diseases in renal biopsy. Correlation of clinical syndromes with histological types].

Renal biopsies studied by light and electron microscopy as well as by immunohistochemistry seem to be continually necessary for an adequate typing and therapy of glomerulonephritis (GN) and other glomerular diseases. Basing on 653 renal biopsies examined in Rostock from 1990 to 1999, the morphological classification in a total of 585 cases with glomerular diseases is presented in comparison to their clinical syndromes according to the WHO classification. A nephrotic syndrome was most frequent and clinically reported in 258 of the 585 biopsy cases with glomerular diseases (44%). It was seen in 77 of the 87 cases with minimal change nephropathy (55%), in 46 of the 74 cases with focal segmental glomerulosclerosis (62%), and in 19 of the 24 diffuse membranous GN cases (79%). The majority of the varying histological subtypes of diffuse GN was not combined with a specific clinical syndrome except of diffuse crescentic GN presenting with a rapidly progressive nephritic syndrome in 14 of 16 cases (88%). IgA nephropathy was the most often diagnosed entity of glomerular diseases found in 122 of the 502 cases with primary or secondary GN (24%). It is obvious that a given morphological GN type can but must not be combined with a specific clinical GN syndrome, so that the clinical importance of renal biopsy is stressed.
