Predicting Adverse Outcomes for Shiga Toxin-Producing Escherichia coli Infections in Emergency Departments. J Pediatr 2021; 232:200-206.e4.

Abstract
OBJECTIVE To assess the performance of a hemolytic uremic syndrome (HUS) severity score among children with Shiga toxin-producing Escherichia coli (STEC) infections and HUS by stratifying them according to their risk of adverse events. The score has not been previously evaluated in a North American acute care setting. STUDY DESIGN We reviewed medical records of children <18 years old infected with STEC and treated in 1 of 38 participating emergency departments in North America between 2011 and 2015. The HUS severity score (hemoglobin [g/dL] plus 2-times serum creatinine [mg/dL]) was calculated using first available laboratory results. Children with scores >13 were designated as high-risk. We assessed score performance to predict severe adverse events (ie, dialysis, neurologic complication, respiratory failure, and death) using discrimination and net benefit (ie, threshold probability), with subgroup analyses by age and day-of-illness. RESULTS A total of 167 children had HUS, of whom 92.8% (155/167) had relevant data to calculate the score; 60.6% (94/155) experienced a severe adverse event. Discrimination was acceptable overall (area under the curve 0.71, 95% CI 0.63-0.79) and better among children <5 years old (area under the curve 0.77, 95% CI 0.68-0.87). For children <5 years, greatest net benefit was achieved for a threshold probability >26%. CONCLUSIONS The HUS severity score was able to discriminate between high- and low-risk children <5 years old with STEC-associated HUS at a statistically acceptable level; however, it did not appear to provide clinical benefit at a meaningful risk threshold.

Bonany P, Bilkis MD, Iglesias G, Braun A, Tello J, Ratto V, Vargas A, Koch E, Jannello P, Monteverde E. Fluid restriction versus volume expansion in children with diarrhea-associated HUS: a retrospective observational study. Pediatr Nephrol 2021; 36:103-109. [PMID: 32681274 DOI: 10.1007/s00467-020-04673-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Revised: 06/07/2020] [Accepted: 06/12/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND Fifty percent of patients with typical diarrhea-associated hemolytic uremic syndrome (D+HUS) require kidney replacement therapy (KRT). In these patients, dehydration worsens disease prognosis. We evaluated dialysis requirement, presence of seizures, and mortality rate among patients diagnosed with D+HUS treated with volume expansion (VE) versus fluid restriction (FR). METHODS Thirty-five patients with D+HUS were enrolled; 16 received VE and 19 were historical patients who received conventional FR. RESULTS Upon admission or during treatment, neither group presented evidence of fluid overload. The VE group received higher volumes of saline (VE 27 ml/kg [10-30] over a 3-h period vs. FR 0 ml), had higher urine output after 12 h (VE vs. FR: OR 6.2 [1.2-41.6], P = 0.03), and required less dialysis (VE 2 [12.5%, CI 95% 0-29] vs. FR 9 [47.4%, CI 95% 24-70], P = 0.035). The VE group had an absolute risk reduction of 0.34 (CI 95% 0.07-0.63); hence, three patients treated with VE were required to avoid one KRT. VE also corrected initial hyponatremia and maintained serum sodium within normal ranges. No statistical differences were observed regarding number of patients with seizures (P = 0.08) or mortality (P = 1.0). CONCLUSIONS VE markedly reduces the number of patients requiring KRT and keeps serum sodium within a normal range. We propose to initially hydrate every patient with D+HUS and without signs of fluid overload, with 10 ml/kg/h 0.9% saline solution IV, over a 3-h period. Afterwards, if urine output is ≥ 0.5 ml/kg/h, it is recommended to not dialyze and continue IV hydration schedule with isotonic (D5) saline solution, according to their needs.
