We observed 73 patients with the hemolytic uremic syndrome (HUS) in 9 years (1980-1988), comprising 34% of patients with acute renal failure treated over the same period. There were 53 boys and 20 girls; 59% were below the age of 2 years and 33% between 2 and 5 years. Acute, usually severe dysentery, responding poorly to various antibiotics, was the prodromal illness in 80%, whereas 12% had watery diarrhea. Most patients had severe renal involvement with anuria in 56% and oliguria in 30%. A polymorphonuclear leukocytosis was present in 85% of cases, but had no correlation with the highest levels of blood urea. Coagulation abnormalities suggesting consumption coagulopathy were found in 24 of 30 cases. The results of stool culture showed Shigella species in 7 cases and nontyphoidal Salmonella in 9. Escherichia coli were isolated in 11 cases, but were not further characterized. Renal biopsy showed total or patchy cortical necrosis in 20 of 50 cases. The patients were managed with supportive care, including transfusion of fresh blood or plasma and dialysis as required. The mortality was 60%, being chiefly related to the duration of renal failure and presence of renal cortical necrosis, whereas persistent dysentery and infections were complicating factors. The presence of convulsions and coagulation defects had no relation to the outcome. Our observations indicate that HUS in children in northern India is mostly related to dysentery, likely to be shigellosis, and is usually associated with severe renal damage and a high death rate.

The spectrum and outcome of acute renal failure (ARF) were studied in 205 children aged between 1 month and 12 yr. There were 145 boys and 60 girls; 23 per cent were below 1 yr and 49 per cent between 1 and 4 yr. The main causes of ARF were haemolytic uraemic syndrome (HUS) in 36 per cent, serious infections in 19 per cent, acute gastroenteritis and dysentery in 17 per cent, glomerulonephritis (GN) in 13 per cent and intravascular haemolysis (IVH) in 6 per cent. Most patients with HUS, serious infections and gastroenteritis were below 5 yr, whereas GN and IVH occurred in older children. HUS was mostly associated with dysentery; Shigella and several other pathogens were isolated from stools in 35 per cent. In most patients with HUS disseminated intravascular coagulation and renal cortical necrosis were present, with a high mortality. The outcome was also poor in infants with serious infections. IVH occurred in patients with G-6-PD deficiency. In such patients and in those with post-streptococcal GN the prognosis was good. Crescentic GN had a poor outcome. Our observations highlight the common and serious nature of ARF in India. However, most of the underlying causes are preventable.

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)

The precise etiology of hemolytic uremic syndrome (HUS) is unknown. However, it has been associated with bacterial (Shigella, Salmonella, E. coli, S. pneumoniae), Bartonella, and viral (coxsackie, ECHO, influenza, varicella. Epstein-Barr) infections and with endotoxemia. Recently, we experienced a case of HUS in a 16-year-old boy who was in the acute phase of an Epstein-Barr virus (EBV) infection. He had typical manifestations of HUS and EBV infection. He also transiently presented disseminated intravascular coagulation. His renal dysfunction recovered by supportive care, including hemodialysis, plasmapheresis, antihypertensive medication and aspirin. We present this case with a review of the literature as the second report of HUS associated with EBV infection.

Shigellosis is still an important public health problem in developing and under-developed countries. It may lead to rare but potentially fatal various extra intestinal complications like septicemia, involvement of CNS, urinary tract and liver especially in young malnourished children. The disease is difficult to prevent as only few bacteria are required for causing infection and there is increasing infection with multi drug resistant strains. A 6-month-old infant developed septicemia caused by multi drug resistant Shigella flexneri during an episode of gastrointestinal infection. The patient was managed in the emergency ward but unfortunately the infant expired. Considering septic shock, blood culture, stool culture and other relevant investigations were done. Stool as well as blood culture yielded Shigella flexneri. The isolates were multidrug resistant. Following is a rare case presentation of Shigella septicemia with severe shock, DIC and convulsions. The case report demonstrates how shigellosis can lead to a rare life threatening complication and hence should be considered as a possibility in septicemia associated with diarrhea and vomiting in infant and young children.
