Objective:To assess changes in the pattern of glomerular diseases to help guide optimal allocation of resources, to focus future reasearch, and improve outcomes.Methods:A retrospective chart review was conducted on kidney biopsies taken between 2007 and 2016 at a single tertiary care center in Saudi Arabia (King Fahad Medical City, Riyadh) to evaluate the prevalence and pattern of glomerulonephritis (GN).Results:The most common primary GN in 102 biopsies from adult patients with a mean age of 28.9 ± 13.6 years and 40.2% female, was focal and segmental glomerulosclerosis (35.3%). Among 64 patients with systemic lupus erythematosus associated nephritis, of whom most (82.8%) were female, lupus nephritis (LN) 4 (46.9%), and (LN) 3 (32.8%) were the most common lupus nephritis classes.Conclusion:Establishing prospective GN registries from which robust diagnosis, treatment, and outcomes data can be acquired is warranted; however, registry development and maintenance are often precluded by resource limitations. Accordingly, retrospective analysis of administrative data will continue to provide important complementary information on GN epidemiology.
