    Abstract:
    BACKGROUND: Diarrhea-associated hemolytic uremic syndrome (D+HUS) causes acute renal failure and may lead to podocyte loss. Objective. To determine if the urinary mRNA excretion of podocyte proteins is detectable in children with D+HUS and if it is a biomarker of a poor long-term outcome. METHODS: Patients were randomly selected from participants in the SYNSORB Pk trial. Urine samples were collected daily during the first week of hospitalization. Specimens were also obtained in healthy volunteers. Synaptopodin and nephrin mRNA levels were measured using real-time PCR. RESULTS: Fifteen children, aged 4.9+/-2.8 years, were studied. Patients were categorized based on urinary mRNA levels into normal (marker:GAPDH<or=mean + SD) or high (marker:GAPDH>mean + SD) in controls. Twelve patients (80%) had increased urinary podocyte mRNA excretion; 11 (73%) had high synaptopodin and 5 (33%) had high nephrin mRNA levels. Follow-up data were available in 13/15 patients, all of whom had normal blood pressure, urinalysis, and serum creatinine concentration. CONCLUSION: The isolation of podocyte mRNA from routine urine samples is feasible in children with D+HUS. Most patients have podocyturia based on synaptopodin and nephrin mRNA excretion. Larger studies with extended follow-up are required to determine the relationship of these biomarkers to long-term renal prognosis in D+HUS.
