Abstract
BACKGROUND: The pattern of glomerular diseases in northwest Iran is unknown. This study was conducted to evaluate the histological pattern of renal diseases in this region. METHODS: We retrospectively studied the reports of 266 native adult renal biopsies at the Imam Reza and Taleghani Hospitals from June 2007 to June 2012. Pathological findings include minimal change disease (MCD), focal segmental glomerulosclerosis (FSGS), mesangioproliferative glomerulonephritis (MPGN), mesangiocapillary glomerulonephritis (MCGN), post streptococcal proliferative glomerulonephritis (PSPGN), membranous glomerulonephritis (MGN), hypertensive nephropathy (HN), crescentic glomerulonephritis or rapid progressive glomerulonephritis (CGN or RPGN), chronic tubular interstitial necrosis (CTIN), chronic sclerosing glomerulonephritis (CGN), Alport syndrome, acute tubular necrosis (ATN), lupus nephritis, renal amyloidosis. The data were collected and analyzed. RESULTS: The mean age of the patients was 37.41±15.78 years. Nephrotic syndrome was observed in 155 (58.3%) cases which was higher in frequency in females (61.9%) (p<0.005), followed by renal insufficiency in 87 (32.7%) cases. Totally, 187 (70.3%) had primary glomerulonephritis (GN) whereas, 79 (29.7%) had secondary GN. MCD was found to be the most common histological pattern (44%) and CGN (1.12%) was the least common. The frequencies of secondary glomerulonephritis (GN) include lupus nephritis to be the most frequent (41.8%) followed by chronic tubulo interstitial nephritis (38%) and type II diabetic nephropathy (19%). CONCLUSION: The results showed that minimal change disease ranked first followed by focal segmental glomerulosclerosis. We hope that this will form the basis for developing a renal biopsy registry across the continent in Iran.
