Traumatic injury clinical trial evaluating tranexamic acid in children (TIC-TOC): a pilot randomized trial.

2022

2022 Mar 10

1553-2712

<p><strong>BACKGROUND: </strong>The antifibrinolytic drug tranexamic acid (TXA) improves survival in adults with traumatic hemorrhage; however, the drug has not been evaluated in a trial in injured children. We evaluated the feasibility of a large-scale trial evaluating the effects of TXA in children with severe hemorrhagic injuries.</p>

<p><strong>METHODS: </strong>Severely injured children (0 up to 18 birthday) were randomized into a double-blind randomized trial of 1) TXA 15 mg/kg bolus dose, followed by 2 mg/kg/hr infusion over 8 hours, 2) TXA 30 mg/kg bolus dose, followed by 4 mg/kg/hr infusion over 8 hours, or 3) normal saline placebo bolus and infusion. The trial was conducted at 4 pediatric Level I trauma centers in the United States between June 2018 and March 2020. We enrolled patients under federal exception from informed consent (EFIC) procedures when parents were unable to provide informed consent. Feasibility outcomes included the rate of enrollment, adherence to intervention arms, and ability to measure the primary clinical outcome. Clinical outcomes included global functioning (primary), working memory, total amount of blood products transfused, intracranial hemorrhage progression, and adverse events. The target enrollment rate was at least 1.25 patients per site per month.</p>

<p><strong>RESULTS: </strong>A total of 31 patients were randomized with a mean age of 10.7 years (standard deviation [SD] 5.0 years) and 22 (71%) patients were male. The mean time from injury to randomization was 2.4 hours (SD 0.6 hours). Sixteen (52%) patients had isolated brain injuries and 15 (48%) patients had isolated torso injuries. The enrollment rate using EFIC was 1.34 patients per site per month. All eligible enrolled patients received study intervention (9 patients TXA 15 mg/kg bolus dose, 10 patients TXA 30 mg/kg bolus dose, and 12 patients placebo) and had the primary outcome measured. No statistically significant differences in any of the clinical outcomes were identified.</p>

<p><strong>CONCLUSION: </strong>Based on enrollment rate, protocol adherence, and measurement of the primary outcome in this pilot trial, we confirmed the feasibility of conducting a large-scale, randomized trial evaluating the efficacy of TXA in severely injured children with hemorrhagic brain and/or torso injuries using EFIC.</p>

2574-3805

<p><strong>Importance: </strong>Severe outcomes among youths with SARS-CoV-2 infections are poorly characterized.</p>

<p><strong>Objective: </strong>To estimate the proportion of children with severe outcomes within 14 days of testing positive for SARS-CoV-2 in an emergency department (ED).</p>

<p><strong>Design, Setting, and Participants: </strong>This prospective cohort study with 14-day follow-up enrolled participants between March 2020 and June 2021. Participants were youths aged younger than 18 years who were tested for SARS-CoV-2 infection at one of 41 EDs across 10 countries including Argentina, Australia, Canada, Costa Rica, Italy, New Zealand, Paraguay, Singapore, Spain, and the United States. Statistical analysis was performed from September to October 2021.</p>

<p><strong>Exposures: </strong>Acute SARS-CoV-2 infection was determined by nucleic acid (eg, polymerase chain reaction) testing.</p>

<p><strong>Main Outcomes and Measures: </strong>Severe outcomes, a composite measure defined as intensive interventions during hospitalization (eg, inotropic support, positive pressure ventilation), diagnoses indicating severe organ impairment, or death.</p>

<p><strong>Results: </strong>Among 3222 enrolled youths who tested positive for SARS-CoV-2 infection, 3221 (&gt;99.9%) had index visit outcome data available, 2007 (62.3%) were from the United States, 1694 (52.6%) were male, and 484 (15.0%) had a self-reported chronic illness; the median (IQR) age was 3 (0-10) years. After 14 days of follow-up, 735 children (22.8% [95% CI, 21.4%-24.3%]) were hospitalized, 107 (3.3% [95% CI, 2.7%-4.0%]) had severe outcomes, and 4 children (0.12% [95% CI, 0.03%-0.32%]) died. Characteristics associated with severe outcomes included being aged 5 to 18 years (age 5 to &lt;10 years vs &lt;1 year: odds ratio [OR], 1.60 [95% CI, 1.09-2.34]; age 10 to &lt;18 years vs &lt;1 year: OR, 2.39 [95% CI 1.38-4.14]), having a self-reported chronic illness (OR, 2.34 [95% CI, 1.59-3.44]), prior episode of pneumonia (OR, 3.15 [95% CI, 1.83-5.42]), symptoms starting 4 to 7 days prior to seeking ED care (vs starting 0-3 days before seeking care: OR, 2.22 [95% CI, 1.29-3.82]), and country (eg, Canada vs US: OR, 0.11 [95% CI, 0.05-0.23]; Costa Rica vs US: OR, 1.76 [95% CI, 1.05-2.96]; Spain vs US: OR, 0.51 [95% CI, 0.27-0.98]). Among a subgroup of 2510 participants discharged home from the ED after initial testing and who had complete follow-up, 50 (2.0%; 95% CI, 1.5%-2.6%) were eventually hospitalized and 12 (0.5%; 95% CI, 0.3%-0.8%) had severe outcomes. Compared with hospitalized SARS-CoV-2-negative youths, the risk of severe outcomes was higher among hospitalized SARS-CoV-2-positive youths (risk difference, 3.9%; 95% CI, 1.1%-6.9%).</p>

<p><strong>Conclusions and Relevance: </strong>In this study, approximately 3% of SARS-CoV-2-positive youths tested in EDs experienced severe outcomes within 2 weeks of their ED visit. Among children discharged home from the ED, the risk was much lower. Risk factors such as age, underlying chronic illness, and symptom duration may be useful to consider when making clinical care decisions.</p>

Serum Sodium Concentration and Mental Status in Children With Diabetic Ketoacidosis.

2021

2021 Aug 09

1098-4275

<p><strong>OBJECTIVES: </strong>Diabetic ketoacidosis (DKA) is typically characterized by low or low-normal serum sodium concentrations, which rise as hyperglycemia resolves. In retrospective studies, researchers found associations between declines in sodium concentrations during DKA and cerebral injury. We prospectively investigated determinants of sodium concentration changes and associations with mental status alterations during DKA.</p>

<p><strong>METHODS: </strong>Using data from the Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation in Diabetic Ketoacidosis Trial, we compared children who had declines in glucose-corrected sodium concentrations with those who had rising or stable concentrations. Children were randomly assigned to 1 of 4 intravenous fluid protocols that differed in infusion rate and sodium content. Data from the first 4, 8, and 12 hours of treatment were analyzed for 1251, 1086, and 877 episodes, respectively.</p>

<p><strong>RESULTS: </strong>In multivariable analyses, declines in glucose-corrected sodium concentrations were associated with higher sodium and chloride concentrations at presentation and with previously diagnosed diabetes. Treatment with 0.45% (vs 0.9%) sodium chloride fluids was also associated with declines in sodium concentration; however, higher rates of fluid infusion were associated with declines in sodium concentration only at 12 hours. Frequencies of abnormal Glasgow Coma Scale scores and clinical diagnoses of cerebral injury were similar in patients with and without declines in glucose-corrected sodium concentrations.</p>

<p><strong>CONCLUSIONS: </strong>Changes in glucose-corrected sodium concentrations during DKA treatment are influenced by the balance of free-water loss versus sodium loss at presentation and the sodium content of intravenous fluids. Declines in glucose-corrected sodium concentrations are not associated with mental status changes during treatment.</p>

Effects of Fluid Rehydration Strategy on Correction of Acidosis and Electrolyte Abnormalities in Children With Diabetic Ketoacidosis.

2021

2021 Jun 29

1935-5548

<p><strong>OBJECTIVE: </strong>Fluid replacement to correct dehydration, acidosis, and electrolyte abnormalities is the cornerstone of treatment for diabetic ketoacidosis (DKA), but little is known about optimal fluid infusion rates and electrolyte content. The objective of this study was to evaluate whether different fluid protocols affect the rate of normalization of biochemical derangements during DKA treatment.</p>

<p><strong>RESEARCH DESIGN AND METHODS: </strong>The current analysis involved moderate or severe DKA episodes ( = 714) in children age &lt;18 years enrolled in the Fluid Therapies Under Investigation in DKA (FLUID) Trial. Children were assigned to one of four treatment groups using a 2 × 2 factorial design (0.90% or 0.45% saline and fast or slow rate of administration).</p>

<p><strong>RESULTS: </strong>The rate of change of pH did not differ by treatment arm, but Pco increased more rapidly in the fast versus slow fluid infusion arms during the initial 4 h of treatment. The anion gap also decreased more rapidly in the fast versus slow infusion arms during the initial 4 and 8 h. Glucose-corrected sodium levels remained stable in patients assigned to 0.90% saline but decreased in those assigned to 0.45% saline at 4 and 8 h. Potassium levels decreased, while chloride levels increased more rapidly with 0.90% versus 0.45% saline. Hyperchloremic acidosis occurred more frequently in patients in the fast arms (46.1%) versus the slow arms (35.2%).</p>

<p><strong>CONCLUSIONS: </strong>In children treated for DKA, faster fluid administration rates led to a more rapid normalization of anion gap and Pco than slower fluid infusion rates but were associated with an increased frequency of hyperchloremic acidosis.</p>

2020

e2025481

2020 Dec 01

2574-3805

<p><strong>Importance: </strong>Acute kidney injury (AKI) occurs commonly during diabetic ketoacidosis (DKA) in children, but the underlying mechanisms and associations are unclear.</p>

<p><strong>Objective: </strong>To investigate risk factors for AKI and its association with neurocognitive outcomes in pediatric DKA.</p>

<p><strong>Design, Setting, and Participants: </strong>This cohort study was a secondary analysis of data from the Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation in DKA Study, a prospective, multicenter, randomized clinical trial comparing fluid protocols for pediatric DKA in 13 US hospitals. Included DKA episodes occurred among children age younger than 18 years with blood glucose 300 mg/dL or greater and venous pH less than 7.25 or serum bicarbonate level less than 15 mEq/L.</p>

<p><strong>Exposures: </strong>DKA requiring intravenous insulin therapy.</p>

<p><strong>Main Outcomes and Measures: </strong>AKI occurrence and stage were assessed using serum creatinine measurements using Kidney Disease: Improving Global Outcomes criteria. DKA episodes with and without AKI were compared using univariable and multivariable methods, exploring associated factors.</p>

<p><strong>Results: </strong>Among 1359 DKA episodes (mean [SD] patient age, 11.6 [4.1] years; 727 [53.5%] girls; 651 patients [47.9%] with new-onset diabetes), AKI occurred in 584 episodes (43%; 95% CI, 40%-46%). A total of 252 AKI events (43%; 95% CI, 39%-47%) were stage 2 or 3. Multivariable analyses identified older age (adjusted odds ratio [AOR] per 1 year, 1.05; 95% CI, 1.00-1.09; P = .03), higher initial serum urea nitrogen (AOR per 1 mg/dL increase, 1.14; 95% CI, 1.11-1.18; P &lt; .001), higher heart rate (AOR for 1-SD increase in z-score, 1.20; 95% CI, 1.09-1.32; P &lt; .001), higher glucose-corrected sodium (AOR per 1 mEq/L increase, 1.03; 95% CI, 1.00-1.06; P = .001) and glucose concentrations (AOR per 100 mg/dL increase, 1.19; 95% CI, 1.07-1.32; P = .001), and lower pH (AOR per 0.1 increase, 0.63; 95% CI, 0.51-0.78; P &lt; .001) as variables associated with AKI. Children with AKI, compared with those without, had lower scores on tests of short-term memory during DKA (mean [SD] digit span recall: 6.8 [2.4] vs 7.6 [2.2]; P = .02) and lower mean (SD) IQ scores 3 to 6 months after recovery from DKA (100.0 [12.2] vs 103.5 [13.2]; P = .005). Differences persisted after adjusting for DKA severity and demographic factors, including socioeconomic status.</p>

<p><strong>Conclusions and Relevance: </strong>These findings suggest that AKI may occur more frequently in children with greater acidosis and circulatory volume depletion during DKA and may be part of a pattern of multiple organ injury involving the kidneys and brain.</p>

Cognitive Function Following Diabetic Ketoacidosis in Children With New-Onset or Previously Diagnosed Type 1 Diabetes.

2020

2020 Sep 22

1935-5548

<p><strong>OBJECTIVE: </strong>This study assessed whether a single diabetic ketoacidosis (DKA) episode is associated with cognitive declines in children with newly diagnosed type 1 diabetes and whether the same is true in children who had previously been diagnosed after accounting for variations in glycemic control and other relevant factors.</p>

<p><strong>RESEARCH DESIGN AND METHODS: </strong>We prospectively enrolled 758 children, 6-18 years old, who presented with DKA in a randomized multisite clinical trial evaluating intravenous fluid protocols for DKA treatment. DKA was moderate/severe in 430 children and mild in 328 children. A total of 392 children with DKA had new onset of type 1 diabetes, and the rest were previously diagnosed. Neurocognitive assessment occurred 2-6 months after the DKA episode. A comparison group of 376 children with type 1 diabetes, but no DKA exposure, was also enrolled.</p>

<p><strong>RESULTS: </strong>Among all patients, moderate/severe DKA was associated with lower intelligence quotient (IQ) (β = -0.12, &lt; 0.001), item-color recall (β = -0.08, = 0.010), and forward digit span (β = -0.06, = 0.04). Among newly diagnosed patients, moderate/severe DKA was associated with lower item-color recall (β = -0.08, = 0.04). Among previously diagnosed patients, repeated DKA exposure and higher HbA were independently associated with lower IQ (β = -0.10 and β = -0.09, respectively, &lt; 0.01) and higher HbA was associated with lower item-color recall (β = -0.10, = 0.007) after hypoglycemia, diabetes duration, and socioeconomic status were accounted for.</p>

<p><strong>CONCLUSIONS: </strong>A single DKA episode is associated with subtle memory declines soon after type 1 diabetes diagnosis. Sizable IQ declines are detectable in children with known diabetes, suggesting that DKA effects may be exacerbated in children with chronic exposure to hyperglycemia.</p>

Hypertension During Diabetic Ketoacidosis in Children.

2020

2020 May 06

1097-6833

<p><strong>OBJECTIVES: </strong>To characterize hemodynamic alterations occurring during diabetic ketoacidosis (DKA) in a large cohort of children and to identify clinical and biochemical factors associated with hypertension.</p>

<p><strong>STUDY DESIGN: </strong>This was a planned secondary analysis of data from the Pediatric Emergency Care Applied Research Network (PECARN) Fluid Therapies Under Investigation in DKA (FLUID) Study, a randomized clinical trial of fluid resuscitation protocols for children in DKA. Hemodynamic data (heart rate, blood pressure) from children with DKA were assessed in comparison with normal values for age and sex. Multivariable statistical modeling was used to explore clinical and laboratory predictors of hypertension.</p>

<p><strong>RESULTS: </strong>Among 1258 DKA episodes, hypertension was documented at presentation in 154 (12.2%) and developed during DKA treatment in an additional 196 (15.6%), resulting in a total of 350 DKA episodes (27.8%) in which hypertension occurred at some time. Factors associated with hypertension at presentation included more severe acidosis, (lower pH and lower PCO), and stage 2 or 3 Acute Kidney Injury (AKI). More severe acidosis and lower Glasgow Coma Scale (GCS) scores were associated with hypertension occurring at any time during DKA treatment.</p>

<p><strong>CONCLUSIONS: </strong>Despite dehydration, hypertension occurs in a substantial number of children with DKA. Factors associated with hypertension include greater severity of acidosis, lower PCO and lower GCS scores during DKA treatment, suggesting that hypertension might be centrally mediated.</p>

Assessment of primary outcome measures for a clinical trial of pediatric hemorrhagic injuries.

2020

2020 Mar 09

1532-8171

<p><strong>OBJECTIVE: </strong>We evaluated the acceptability of the Pediatric Quality of Life Inventory (PedsQL) and other outcomes as the primary outcomes for a pediatric hemorrhagic trauma trial (TIC-TOC) among clinicians.</p>

<p><strong>METHODS: </strong>We conducted a mixed-methods study that included an electronic questionnaire followed by teleconference discussions. Participants confirmed or rejected the PedsQL as the primary outcome for the TIC-TOC trial and evaluated and proposed alternative primary outcomes. Responses were compiled and a list of themes and representative quotes was generated.</p>

<p><strong>RESULTS: </strong>73 of 91 (80%) participants completed the questionnaire. 61 (84%) participants agreed that the PedsQL is an appropriate primary outcome for children with hemorrhagic brain injuries. 32 (44%) participants agreed that the PedsQL is an acceptable primary outcome for children with hemorrhagic torso injuries, 27 (38%) participants were neutral, and 13 (18%) participants disagreed. Several themes were identified from responses, including that the PedsQL is an important and patient-centered outcome but may be affected by other factors, and that intracranial hemorrhage progression assessed by brain imaging (among patients with brain injuries) or blood product transfusion requirements (among patients with torso injuries) may be more objective outcomes than the PedsQL.</p>

<p><strong>CONCLUSIONS: </strong>The PedsQL was a well-accepted proposed primary outcome for children with hemorrhagic brain injuries. Traumatic intracranial hemorrhage progression was favored by a subset of clinicians. A plurality of participants also considered the PedsQL an acceptable outcome for children with hemorrhagic torso injuries. Blood product transfusion requirement was favored by fewer participants.</p>

PRagMatic Pediatric Trial of Balanced versus nOrmaL Saline FlUid in Sepsis: the PRoMPT BOLUS Randomized Controlled Trial Pilot Feasibility Study.

2019

2019 Jun 10

1553-2712

<p><strong>BACKGROUND: </strong>Resuscitation with crystalloid fluid is a cornerstone of pediatric septic shock treatment. However, the optimal type of crystalloid fluid is unknown. We aimed to determine the feasibility of conducting a pragmatic randomized trial to compare balanced (lactated Ringer's [LR]) with 0.9% normal saline (NS) fluid resuscitation in children with suspected septic shock.</p>

<p><strong>METHODS: </strong>Open-label pragmatic randomized controlled trial (RCT) at a single academic children's hospital from January - August 2018. Eligible patients were &gt;6 months to &lt;18 years-old who were treated in the emergency department for suspected septic shock, operationalized as blood culture, parenteral antibiotics, and fluid resuscitation for abnormal perfusion. Screening, enrollment, and randomization were carried out by the clinical team as part of routine care. Patients were randomized to receive either LR or NS for up to 48 hours following randomization. Other than fluid type, all treatment decisions were at the clinical team's discretion. Feasibility outcomes included proportion of eligible patients enrolled, acceptability of enrollment via the U.S. federal exception from informed consent (EFIC) regulations, and adherence to randomized study fluid administration.</p>

<p><strong>RESULTS: </strong>Of 59 eligible patients, 50 (85%) were enrolled and randomized. Twenty four were randomized to LR and 26 to NS. Only one (2%) of 44 patients enrolled using EFIC withdrew before study completion. Total median crystalloid fluid volume received during the intervention window was 107 (IQR 60, 155) mL/kg and 98 (IQR 63, 128) mL/kg in the LR and NS arms, respectively (p=0.50). Patients randomized to LR received a median of only 20% (IQR 13, 32) of all study fluid as NS compared to 99% (IQR 64,100%) of study fluid as NS in the NS arm (absolute difference 79%, 95% CI 48,85).</p>

<p><strong>CONCLUSIONS: </strong>A pragmatic study design proved feasible to study comparative effectiveness of LR versus NS fluid resuscitation for pediatric septic shock. This article is protected by copyright. All rights reserved.</p>
