A retrospective study of 76 children with hemolytic uremic syndrome (HUS) who were admitted to the Alberta Children's Hospital in Calgary. Alberta between January 1982 and December 1988 was undertaken to explore the gastrointestinal manifestations of the syndrome. The children (mean age of 4.0 +/- 3.1 years) presented primarily during the summer months with a microangiopathic hemolytic anemia (Hgb 94 +/- 26 g/L), thrombocytopenia (platelets 87 +/- 83 X 10(9)/L), and acute renal failure (oligoanuria with a BUN of 26 +/- 15 mmol/L, and a creatinine of 294 +/- 90 mumol/L). Forty-three children required dialysis for 10 +/- 17 days. The duration of hospitalization was 17 +/- 17 days. Four children died of complications attributable to HUS. The following symptoms and gastrointestinal manifestations of HUS were noted: fever (33%), vomiting (80%), abdominal discomfort/tenderness (59%), diarrhea (100%), hemorrhagic colitis (79%), rectal prolapse (13%), colonic stricture (3%), colonic perforation (1%), intussusception (1%), indirect hyperbilirubinemia (49%), and elevated hepatocellular enzymes (58%). Of the last 29 children studied, 19 (66%) had elevated levels of amylase and lipase in the presence of acute renal failure, and six (21%) had a marked elevation of lipase (more than four times normal) with additional supportive evidence of pancreatitis. The additional supportive evidence included persistent elevation of lipase after the resolution of acute renal failure in four children, a marked increment in lipase in association with abdominal pain and an abnormal ultrasound of the pancreas after the initiation of oral feeding in a fifth child, and pancreatic exocrine and endocrine necrosis at autopsy in a sixth child.(ABSTRACT TRUNCATED AT 250 WORDS)

Nine children with acute typical post-diarrhea hemolytic uremic syndrome (HUS) were treated with intravenous gammaglobulin (IVIG). These children were compared to nine children with HUS who did not receive IVIG. The use of IVIG did not appear to have a beneficial effect on eight of the nine treated children. There were no significant differences found in the duration of hemorrhagic colitis, thrombocytopenia, elevation of the white blood count (WBC), anuria, dialysis, or hospitalization, or the presence of a central nervous system complication or pancreatitis. Although no significant difference was found in the duration of thrombocytopenia, there was a trend towards a longer duration of thrombocytopenia in children treated with IVIG (P = 0.13). One child demonstrated both an increase in her platelet count and a decrease in her WBC count within 24 h of receiving her first dose of IVIG.

Hemolytic-uremic syndrome (HUS) of childhood is a triad of acute hemolytic anemia, thrombocytopenia, and acute renal failure associated with a gastrointestinal prodrome. From 1977 to 1988, 134 patients with HUS were admitted to this institution. All patients presented with abdominal pain and diarrhea, which was virtually always bloody. Seventy-eight patients (60%) required dialysis. Five patients died (4%). One patient died as a result of colon perforation, the other four patients died of other nonsurgical complications of HUS. Three patients underwent exploratory laparotomy. One patient had a hemoperitoneum from mesenteric and transmural bleeding of the entire intraabdominal colon. Another patient had undergone surgery elsewhere for presumed intussusception with pancolitis found at exploration. Fourteen days postoperatively, he had a spontaneous perforation of the transverse colon. The third patient presented with pancolitis and perforation of the transverse colon. Despite surgical intervention he died on the sixth postoperative day. One other patient was treated conservatively for pancreatitis, which developed 3 weeks after her presentation with HUS. Complications requiring surgical intervention in HUS are rare, potentially lethal, and usually involve the colon.

We employed a radioimmunoassay for human cationic trypsin to define the time course for alterations in the molecular forms of this enzyme in plasma from patients with pancreatitis. Six patients developed acute pancreatitis as a complication of a known disorder [three, Reye's syndrome; two, hemolytic uremic syndrome (HUS); one, choledochal cyst]. The immunoreactive forms of cationic trypsin were determined by gel filtration of each plasma sample followed by radioimmunoassay of the column fractions. Early in the course of the disease, predominantly free trypsinogen was released into the circulation in five patients. In the three patients with Reye's syndrome, subsequent plasma samples showed, in addition to free trypsinogen, increasing amounts of immunoreactive trypsin complexed to alpha 2-macroglobulin and alpha 1-protease inhibitor. In contrast, subsequent samples from the two patients with HUS contained little or no inhibitor-bound trypsin. The remaining patient had intermediate concentrations of cationic trypsin complexed to these two circulating protease inhibitors. Five patients died and postmortem studies showed a striking correlation between the histological severity of acute pancreatic inflammation and the amount of immunoreactive trypsin complexed to alpha 2-macroglobulin and alpha 1-protease inhibitor. This preliminary study suggests that measurement of alpha 2-macroglobulin or alpha 1-protease inhibitor-bound trypsin may be a useful method of monitoring the progression and severity of disease in patients with acute pancreatitis. Characterization of serial changes in the forms of circulating pancreatic proteases may enhance our understanding of time-dependent pathophysiologic events, possibly leading to improved forms of specific therapy.

Pancreatitis is a rare (approximately 2.0%) complication of thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS). The opposite finding has rarely been reported. We present a case of an 18 years old obese male with alcohol associated pancreatitis (amylase 840 IU/L) who three days after onset, as the pancreatitis subsided (amylase 341 U/L), developed TTP/HUS. The TTP/HUS was marked by oliguria and severe renal failure (creatinine 1,326 mumol/L), was treated with daily plasma exchanges, obtained a complete response, and recovered renal function (creatinine 115 mumol/L). Similarly, in six of seven other cases from the medical literature the TTP/HUS occurred within 2-3 days of the onset of pancreatitis.

We conducted a retrospective analysis of 37 children with Escherichia coli O157:H7-associated hemolytic-uremic syndrome. The infection was traced to contaminated hamburgers at a fast-food restaurant chain. Within 5 days of the first confirmed case, the Washington State Department of Health identified the source and interrupted transmission of infection. Ninety-five percent of the children initially had severe hemorrhagic colitis. Nineteen patients (51%) had significant extrarenal abnormalities, including pancreatitis, colonic necrosis, glucose intolerance, coma, stroke, seizures, myocardial dysfunction, pericardial effusions, adult respiratory disease syndrome, and pleural effusions. Three deaths occurred, each in children with severe multisystem disease. At follow-up two children have significant impairment of renal function (glomerular filtration rate < 80 ml/min/per 1.73 Hm2); both of these children have a normal serum creatinine concentration. Hemolytic-uremic syndrome is the most common cause of acute renal failure in children, and this experience emphasizes the systemic nature of this disease. Clinicians should anticipate that multisystem involvement may occur in these patients, necessitating acute intervention or chronic follow-up. This outbreak of Hemolytic-uremic syndrome also highlights the microbiologic hazards of inadequately prepared food and emphasizes the importance of public health intervention in controlling Hemolytic-uremic syndrome.

A 15-year-old girl had severe Raynaud's phenomenon and arthralgias. A high ANA-IF titer was found and undifferentiated connective tissue disease was diagnosed. After 7 years of moderately flaring disease the patient deteriorated and presented with congestive heart failure, pleuropericardial effusion, hemolytic uremic syndrome, proteinuria and moderate hypertension. Autoantibodies against DNA, Sm-protein, and very high titers against U1RNP were detected. Therapy with high steroid doses, a cyclophosphamide pulse and 4 weeks of plasmaphresis with plasma exchange improved the heart, but not the renal condition. Symptomatic pancreatitis became the dominant problem of a progressively consuming process that resulted in the death of the patient. Post-mortem examination revealed widespread vasculopathy with intima proliferation and only minimal fibrosis involving the kidneys, heart and other main organs, including the pancreas. Taken together, the clinical picture was of an overlap between scleroderma and systemic lupus erythemathosus; the serologic and histopathologic findings suggest a diagnosis of a severe form of mixed connective tissue disease (MCTD).

Sequelae of Escherichia coli O157:H7-associated hemolytic uremic syndrome (HUS) 2-3 years following an outbreak in Washington State have been prospectively studied to identify predictors of adverse sequelae. Logistic regression analysis was used to examine associations between findings in the acute course and long-term renal and gastrointestinal outcomes. Twenty-one percent of patients had gastrointestinal sequelae, which included cholelithiasis resulting in cholecystectomy (3/29), persistent pancreatitis (2/29), late colon stricture (1/29), and/or glucose intolerance (1/29). Logistic regression analysis found long-term gastrointestinal sequelae were higher in patients who, during HUS, had hypertension [odds ratio (OR) = 21.2, 95% confidence interval (CI) = 1.9-164.4, P = 0.01] or gastrointestinal complications (OR = 21.2, 95% CI = 1.9-164.4, P = 0.01). Renal sequelae were seen in 35% of patients. One patient (4%) had persistent hypertension and 9 (31%) had minor urinary findings (hematuria or proteinuria). Thrombocytopenia lasting longer than 10 days during the acute illness was associated with a risk for subsequent renal sequelae (OR = 15.0, 95% CI = 1.98-1,703.0, P = 0.009). We conclude a high incidence of gastrointestinal sequelae, especially cholelithiasis presenting long after the acute illness, may be seen with HUS. The short follow-up period may underestimate the extent and severity of eventual renal sequelae.

Presented is a study of 15 patients (seven males and eight females ranging between 5 and 10 years of age) with hemolytic uremic syndrome (HUS) associated with hemorrhagic colitis that was caused by enterohemorrhagic Escherichia coli (EHEC) O157:H7, encountered during the outbreak in Sakai City in July, 1996. The complete form of HUS, which includes the three characteristics hemolytic anemia, thrombocytopenia and acute renal dysfunction, was noted in eight patients, while an incomplete form of HUS, which did not include all three characteristics, was noted in seven patients. Regarding treatment, intravenous gamma-globulin was administered in nine patients and dialysis was performed in five patients (two males and three females) with the complete form of HUS. In three of these five patients, plasma exchange was also performed. Weaning from dialysis was accomplished by the 15th day of disease in all patients. Some patients developed pancreatitis, central nervous system symptoms, fundal hemorrhage and elevation of transaminase, although these abnormalities subsided uneventfully. Renal biopsy, which was performed in two patients who recovered from acute renal failure but still had mild proteinuria and a decrease in creatinine clearance, showed moderate changes in the glomeruli and tubulointerstitium. One year after onset of disease, hematological and urological findings were within normal limits in all patients except one with the complete form of HUS, who still had slightly decreased creatinine clearance.

The authors experienced an extremely rare case of secondary sclerosing cholangitis and portal hypertension developed as late complications of hemolytic uremic syndrome (HUS) owing to Escherichia coli O157:H7 in a 2-year-old boy. HUS after E coli O157 infection is the most frequent cause of acute renal failure in childhood and occasionally is accompanied by extrarenal complications such as encephalopathy, cardiomyopathy, ischemic colitis, and pancreatitis. Rarely, late colonic stenosis may develop secondary to the ischemic damage. Sclerosing cholangitis and subsequent cirrhosis with portal hypertension are very uncommon as late complications of HUS. To our knowledge, such a case has not been previously reported in the literature. J Pediatr Surg 36:1838-1840.
