| Abstract |
Hemolytic uremic syndrome (HUS) is defined as microangiopathic hemolytic anemia, thrombocytopenia and uremia. It is an important cause of acute renal failure (ARF) in children all over the world. The present study was carried out to assess the incidence, clinical presentation, hematological and biochemical profile of children presenting with HUS from 1987 to 1990. Out of the 100 cases who presented with ARF 22 had HUS. A majority of these children were males below 1 year of age, and had a prodromal phase of mainly gastrointestinal manifestations lasting for about a week. Anemia was a constant feature followed by bleeding diathesis, mainly melena and purpura. Neurological manifestations included altered sensorium, irritability, coma, hypertensive encephalopathy and convulsions. Renal problems mainly included oliguria, hypertension, hematuria and edema. Investigations revealed thrombocytopenia and microangiopathic hemolytic anemia in all cases. Evidence of disseminated intravascular coagulation (DIC) was observed in 3 cases as decreased fibrinogen levels, increased fibrinogen degradation products and deranged clotting studies. Blood biochemistry revealed azotemia in all cases, hyponatremia in 5 cases, hypernatremia in 3 cases and hyperkalemia in 12 cases. Stool culture showed the presence of Shigella in 8, E. coli in 6 and Klebsiella in 4 cases. Out of 22 cases of HUS, 15 were treated conservatively; of these 2 died. Both of these deaths were due to DIC 7 children were put on peritoneal dialysis; only 1 child died in this group. Factors affecting the outcome were duration of oliguria, levels of blood urea and presence of encephalopathy.(ABSTRACT TRUNCATED AT 250 WORDS)
