Prevalence of glomerular diseases : King Khalid university hospital, Saudi Arabia

الملخص EN

To obtain a more recent and comprehensive insight into the prevalence of glomerular diseases in our patient population, medical records of 200 patients with biopsy proven glomerulonephritis (GN), between January 1994 and June 1999, at the King Khalid University Hospital, Riyadh, Saudi Arabia were analyzed.

Primary glomerular disease was found to be the most prevalent, accounting for 63.5 % of all glomerular diseases.

Among primary glomerular diseases, focal and segmental glomerulosclerosis (FSGS) was the most common histological lesion (34.6 %) and was associated with a high prevalence of hypertension (86.4 %), nephrotic syndrome (68.18 %), hematuria (63.6 %) and renal functional impairment (27.3 %).

Mesangioproliferative GN was the second most common lesion (25.1 %) followed by mesangiocapillary GN (15.7 %), IgA nephropathy (10.2 %), and minimal change disease (8.5 %).

Amongst secondary glomerular diseases, lupus nephritis was the most prevalent (24.5 %).

In conclusion, primary glomerular diseases constituted the commonest group encountered and the prevalence of FSGS was quite high with male sex and young adults predominating.

FSGS was also associated with a high prevalence of endstage renal disease.

Further collaborative studies are necessary to explore the predisposing factors and associations of glomerular disease, especially FSGS.
