Insights
An oral Shiga toxin-binding agent did not reduce the severity of diarrhea-associated hemolytic uremic syndrome (HUS) in children. This study found no significant difference in death, serious events, or dialysis needs between treated and placebo groups.
Area of Science:
- Pediatric Nephrology
- Infectious Diseases
- Gastroenterology
Background:
- Diarrhea-associated hemolytic uremic syndrome (HUS) is a leading cause of acute kidney failure in children.
- Shiga toxin-producing Escherichia coli strains are the primary cause of HUS.
- Effective treatments to mitigate HUS severity are critical.
Purpose of the Study:
- To evaluate the efficacy of an oral Shiga toxin-binding agent in reducing HUS severity.
- To assess the impact of the agent on mortality and renal outcomes in pediatric HUS patients.
Main Methods:
- A multicenter, randomized, double-blind, placebo-controlled trial involving 145 pediatric patients.
- Patients received either the Shiga toxin-binding agent or a placebo for 7 days.
- Outcomes measured included death, serious extrarenal events, and need for dialysis.
Main Results:
- No significant difference in the combined frequency of death or serious extrarenal events between the experimental (18%) and placebo (20%) groups (P=.82).
- The need for dialysis was similar in both groups: 42% in the experimental group and 39% in the placebo group (P=.86).
- Disease severity at randomization was comparable between groups.
Conclusions:
- Oral therapy with a Shiga toxin-binding agent was ineffective in diminishing the severity of diarrhea-associated HUS in pediatric patients.
- Further research may be needed to explore alternative therapeutic strategies for HUS.
Context:
Diarrhea-associated hemolytic uremic syndrome (HUS) is the most common cause of acute renal failure in children. Most cases are caused by an intestinal infection with Shiga toxin-producing strains of Escherichia coli.
Objective:
To determine if administration of an oral agent that binds Shiga toxin could diminish the severity of diarrhea-associated HUS in pediatric patients.
Design, Setting, And Patients:
Multicenter, randomized, double-blind, placebo-controlled clinical trial of 145 children (96 experimental and 49 placebo) aged 6 months to 18 years with diarrhea-associated HUS conducted between July 27, 1997, and April 14, 2001, at 26 tertiary care pediatric nephrology centers in the United States and Canada. Trial included 2 phases, the hospital course for treatment of the acute illness and a 60-day outpatient follow-up period after discharge from the hospital.
Intervention:
Patients were assigned to receive the binding agent, 500 mg/kg daily, or cornmeal placebo orally for 7 days in a 2:1 randomization scheme.
Main Outcome Measures:
Combined frequency of death or serious extrarenal events and need for dialysis in the experimental vs placebo group.
Results:
A total of 62 patients (43%) were male and 123 (85%) were white. The median age of the patients was 4.2 years. Most patients (59%) were transferred from other hospitals to participating sites. The severity of disease at the time of randomization was comparable in the 2 groups. The prevalence of death or serious extrarenal events was 18% and 20% in the experimental and placebo groups, respectively (P =.82). Dialysis was required in 42% of experimental and 39% of placebo groups (P =.86).
Conclusions:
Oral therapy with a Shiga toxin-binding agent failed to diminish the severity of disease in pediatric patients with diarrhea-associated HUS.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
