Relationship of the recovery in the glomerular filtration rate to the duration of anuria in diarrhea-associated hemolytic uremic syndrome.

The relationship of the duration of anuria to the recovery in glomerular filtration rate (GFR) was studied in 71 children with diarrhea-associated hemolytic uremic syndrome. A significant relationship was found, and regression analysis revealed that y = 114.61 - 5.68 x, where y is predicted GFR (ml/min/1.73 m2) and x is the square root of the duration of anuria in days. The presence of hypertension or proteinuria on follow-up was significantly related to the duration of anuria (p = 0.005 and p = 0.002, respectively).
