Hyperhydration to Improve Kidney Outcomes in Children With Shiga Toxin-Producing E. Coli Infection: A Multinational Embedded Cluster Crossover Randomized Trial

Description

The objective of this study is to determine if early high volume intravenous fluid administration (hyperhydration) may be effective in mitigating or preventing complications of shiga toxin-producing E. coli (STEC) infection in children and adolescents when compared with traditional approaches (conservative fluid management).The hemolytic uremic syndrome (HUS) is the most serious complication of high-risk Shiga toxin-producing Escherichia coli (STEC) infection and the most common cause of acquired acute kidney injury in otherwise healthy children. HUS develops in up to 20% of children following STEC infection, 60% of whom require temporary renal replacement therapy (RRT); an additional 50% develop serious extrarenal complications. Although mortality from acute HUS is low (1-3%), it has remained constant for three decades and approximately 30% of HUS survivors experience long-term sequelae, chiefly chronic kidney disease, hypertension, and diabetes. There have been only three relatively

Trial Eligibility

Inclusion Criteria: In order to be eligible to participate in this study (i.e., to be enrolled in the relevant institutional clinical care pathway), an individual must meet all of the following criteria: 1. Aged 9.0 months to \<21 years at the time of informed consent. 2. Evidence of high-risk STEC infecting pathogen defined by any of the following: 1. Bloody diarrhea within the preceding 7 days * Positive STEC culture OR * Positive antigen/polymerase chain reaction test for toxin/gene type not otherwise specified OR 2. Bloody or Non-bloody diarrhea within the preceding 7 days •Presumptive diagnosis of HUS * (meeting all 3 HUS criteria - anemia, thrombocytopenia, and renal insufficiency) OR 3. Non-bloody or no diarrhea * Positive STEC culture for high-risk strain (i.e., O103, O104, O111, O113, O121, O145 or O157) OR * Positive antigen/polymerase chain reaction test Stx2 toxin/gene Exclusion Criteria: All individuals meeting any of the exclusion criteria at baseline will be excluded from study participation. 1. Presence of Advanced HUS defined by: 1. Hematocrit \<30% AND 2. Platelet count \<150 x 103/mm3 AND 3. Creatinine \> 2.0 mg/dL (177 µmol/L) * The presence of only 1 or 2 of these criteria will not result in patient exclusion, regardless of how close the 3rd criterion is to meeting the exclusion criteria. 2. Prior episode of HUS or diagnosis of atypical HUS. 3. Chronic disease limiting fluid volumes administered (e.g. impaired renal, liver, or cardiac function, chronic lung disease). 4. Evidence of anuria (i.e., no urine output for \> 24 hours). 5. Hypoxemia requiring oxygen therapy 6. Hypertensive emergency 7. Greater than or equal to 10 days since onset of diarrhea or if no diarrhea then the onset of other symptoms. 8. Patients with known pregnancy 9. Patients or caregivers with language barriers impairing appropriate conduct of the study protocol.
