Clinical profile of acute renal failure in children admitted to the department of pediatrics, Tikur Anbessa Hospital.

Case records of 30 pediatric patients with the diagnosis of acute renal failure (ARF) admitted to Tikur Anbessa Hospital in Addis Ababa between October 1997 and October 2001 were analyzed There were 15 females and 15 males. Three patients had glomerulonephritis, in two patients the cause of acute renal failure was not known, one child had obstructive uropathy. Twenty-three patients had post-diarrheal hemolytic uremic syndrome. The age ranges of post-diarrheal hemolytic uremic syndrome cases were between 0.6 years and 7 years with a median age of 2.2 years. Fourteen patients died of acute renal failure among this hemolytic urmic syndrome contributed to the death of 9 patients. The commonest clinical presentation was severe oligo-anuria in (25 patients), edema in (22 patients), and bloody diarrhea in (21 patients). From stool cultures of 16 patients with hemolytic uremic syndrome, there were five isolates of Shigella species, two isolates of E. coli, and two isolates of Salmonella species. Five patients had non-oliguric acute renal failure. Hemolytic uremic syndrome is the leading cause of acute renal failure in infants and young children in our series. Vigorous resuscitation and early dialysis will reduce mortality rate.
