[Epidemiology of glomerular disease in adults: a database review]

Glomerular disease is among the top ten leading causes of death in Mexico.

To assess the frequency of glomerulopathy in western Mexico in a Regional Hospital belonging of the Instituto Mexicano Del Seguro Social.

Single hospital center retrospective analysis. We reviewed all native kidney biopsies between January 2003 and December 2011, in patients more than 16 years old, to establish clinical features, presentation, and histological report.

A total of 163 reports were analyzed; patients with a mean age of 32.6 ± 13.3 years, 55% female, 24% had systemic arterial hypertension, and 10% with a family history of chronic renal failure. The most frequent types of primary glomerulonephritis were focal segmental glomerulosclerosis (FSGS) in 47% of cases, followed by membranous nephropathy in 15%. The most frequent types of secondary glomerulonephritis were lupus nephritis in 14%, followed by diabetic nephropathy in 4% and amyloidosis in 1.2%.

Focal segmental glomerulosclerosis is the most frequent type of glomerulopathy in our population; we observed a minor percentage of Inmunoglobulin A (IgA) nephropathy compared with worldwide reports. This information is a contribution to the understanding of the prevalence of glomerulopathy in western Mexico.
