Abstract
BACKGROUND & AIMS This randomized controlled trial (RCT) was conducted with the aim to evaluate the efficacy and safety of using ROTEM-based transfusion strategy in cirrhotic children undergoing invasive procedures. METHODS This was a open-label, RCT which included (i) children under 18 years of age with liver cirrhosis; (ii) INR between 1.5 and 2.5; and/or (iii) platelet count between 20x10(9) /L to 50x10(9) /L (for procedures other than liver biopsy) and between 40x10(9) /L to 60x10(9) /L (for liver biopsy); and (iv) listed for invasive procedures. Stratified randomization was done for children undergoing liver biopsies. Patients randomized to the ROTEM and conventional groups received blood component transfusion using predefined criteria. RESULTS A total of 423 invasive procedures were screened for inclusion of which 60 were randomized (30 in each group with comparable baseline parameters). The volume of total blood components, fresh frozen plasma (FFP) and platelets transfused was significantly lower in ROTEM as compared to conventional group. Only 46.7% of children in ROTEM group received a blood component compared to 100% in conventional group (p<0.001). The requirement of FFP (ROTEM 43.3%, Conventional: 83.3%, p = 0.001) was significantly lower in the patients receiving ROTEM guided transfusions. There was no difference in procedure related bleed and transfusion related complications between the 2 groups. ROTEM was cost effective (p=0.002) despite the additional cost of the test. CONCLUSION ROTEM-based transfusion strategies result in lower blood component transfusion in cirrhotic children undergoing invasive procedures without an increase in risk of procedure-related bleed. ROTEM-guided transfusion strategy is cost-effective.
PICO Summary
Population
Children with liver cirrhosis undergoing invasive procedures (n= 60).
Intervention
ROTEM-based transfusion strategy (n= 30).
Comparison
Conventional coagulation tests-based transfusion strategy (n= 30).
Outcome
The volume of total blood components, fresh frozen plasma (FFP) and platelets transfused was significantly lower in ROTEM as compared to conventional group. Only 46.7% of children in ROTEM group received a blood component compared to 100% in conventional group. The requirement of FFP (ROTEM: 43.3%, conventional: 83.3%) was significantly lower in the patients receiving ROTEM guided transfusions. There was no difference in procedure related bleed and transfusion related complications between the two groups. ROTEM was cost-effective despite the additional cost of the test.

Abstract
BACKGROUND Erythropoiesis-stimulating agents (ESAs) revolutionized the management of anaemia in chronic kidney disease (CKD) when introduced in the late 1980s. A range of ESA types, preparations and administration modalities now exist, with newer agents requiring less frequent administration. Although systematic reviews and meta-analyses have been published in adults, no systematic review has been conducted investigating ESAs in children. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-analyses statement for the conduct of systematic reviews was used. All available literature on outcomes relating to ESAs in children with CKD was sought. A search of the MEDLINE, CINAHL and Embase databases was conducted by two independent reviewers. Inclusion criteria were published trials in English, children with chronic and end-stage kidney disease and use of any ESA studied against any outcome measure. An assessment of risk of bias was carried out in all included randomized trials using the criteria from the Cochrane Handbook for Systematic Reviews of Interventions. Two tables were used for data extraction for randomized and observational studies. Study type, participants, inclusion criteria, case characteristics, follow-up duration, ESA type and dosage, interventions and outcomes were extracted by one author. RESULTS Of 965 identified articles, 58 were included covering 54 cohorts. Six were randomized trials and 48 were observational studies. A total of 38 studies assessed the efficacy of recombinant human erythropoietin (rHuEPO), 11 of darbepoetin alpha (DA) and 3 of continuous erythropoietin receptor activator (CERA), with 6 studies appraising secondary outcome measures exclusively. Recruitment to studies was a consistent challenge. The most common adverse effect was hypertension, although confounding effects often limited direct correlation. Two large cohort studies demonstrated a greater hazard of death independently associated with high ESA dose. Secondary outcome measures included quality of life measures, growth and nutrition, exercise capacity, injection site pain, cardiovascular function, intelligent quotient, evoked potentials and platelet function. CONCLUSIONS All ESA preparations and modes of administration were efficacious, with evidence of harm at higher doses. Evidence supports individualizing treatments, with strong consideration given to alternate treatments in patients who appear resistant to ESA therapy. Further research should focus on randomized trials comparing the efficacy of different preparations, treatment options in apparently ESA-resistant cohorts and clarification of meaningful secondary outcomes to consolidate patient-relevant indices.

Abstract
OBJECTIVE To determine whether intravenous (IV) or oral iron suppletion is superior in improving physical fitness in anemic children with inflammatory bowel disease (IBD). STUDY DESIGN We conducted a clinical trial at 11 centers. Children aged 8 to 18 with IBD and anemia (defined as hemoglobin (Hb) z-score < -2) were randomly assigned to a single IV dose of ferric carboxymaltose or 12 weeks of oral ferrous fumarate. Primary endpoint was the change in 6-minute walking distance (6MWD) from baseline, expressed as z-score. Secondary outcome was a change in Hb z-score from baseline. RESULTS We randomized 64 patients (33 IV iron; 31 oral iron) and followed them for 6 months. One month after the start of iron therapy, the 6MWD z-score of patients in the IV group had increased by 0.71 compared with -0.11 in the oral group (P=0.01). At 3- and 6-months follow-up, no significant differences in 6MWD z-scores were observed. Hb z-scores gradually increased in both groups and the rate of increase was not different between groups at 1, 3 and 6 months after initiation of iron therapy (overall P=0.97). CONCLUSION In this trial involving anemic children with IBD, a single dose of IV ferric carboxymaltose was superior to oral ferrous fumarate with respect to quick improvement of physical fitness. At 3 and 6 months after initiation of therapy, no differences were discovered between oral or IV therapy. The increase of Hb over time was comparable in both treatment groups. TRIAL REGISTRATION NTR4487 [Netherlands Trial Registry].
PICO Summary
Population
Children with anaemia and inflammatory bowel disease, enrolled in the POPEYE trial, in 9 Dutch and 2 Belgian hospitals (n= 64).
Intervention
Single intravenous dose of ferric carboxymaltose (IV group), (n= 33).
Comparison
12 weeks of oral ferrous fumarate (oral group), (n= 31).
Outcome
The primary endpoint was the change in 6-minute walking distance (6MWD) from baseline, expressed as z-score. The secondary outcome was a change in Hb z-score from baseline. One month after the start of iron therapy, the 6MWD z-score of patients in the IV group had increased by 0.71 compared with -0.11 in the oral group. At 3- and 6- months follow-up, no significant differences in 6MWD z-scores were observed. Hb z-scores gradually increased in both groups and the rate of increase was not different between groups at 1, 3 and 6 months after initiation of iron therapy.

Abstract
IMPORTANCE Intraventricular hemorrhage (IVH) is a major cause of neonatal morbidity and mortality in preterm infants without a specific medical treatment to date. OBJECTIVE To assess the safety and short-term outcomes of high-dose erythropoietin in preterm infants with IVH. DESIGN, SETTING, AND PARTICIPANTS Between April 1, 2014, and August 3, 2018, a randomized double-blind clinical trial enrolled 121 preterm infants (gestational age <32 weeks or birth weight <1500 g) aged 8 or less days with moderate to severe IVH identified by cerebral ultrasonography from 8 Swiss and Austrian tertiary neonatal units. Statistical analyses were performed between October 1, 2019, and September 12, 2022. INTERVENTIONS Infants received intravenous high-dose erythropoietin (2000 units/kg body weight) or placebo at 4 time points between weeks 1 and 4 of life. MAIN OUTCOMES AND MEASURES Secondary outcomes included (1) mortality and morbidity rates and (2) brain magnetic resonance imaging findings at term-equivalent age (TEA). The primary outcome was the composite intelligence quotient at 5 years of age (not available before 2023). RESULTS Sixty infants (48% male [n = 29]) were randomly assigned to receive erythropoietin, and 61 infants (61% male [n = 37]) were randomly assigned to receive placebo. The median birth weight was 832 g (IQR, 687-990 g) in the erythropoietin group and 870 g (IQR, 680-1110 g) in the placebo group. Median gestation was 26.1 weeks (IQR, 24.8-27.3 weeks) in the erythropoietin group and 27.0 weeks (24.9-28.1 weeks) in the placebo group. The 2 groups had similar baseline characteristics and morbidities. Up to TEA, 10 newborns died (16.7%) in the erythropoietin group, and 5 newborns (8.2%) died in the placebo group (adjusted odds ratio, 2.24 [95% CI, 0.74-7.66]; P = .15). Infants receiving erythropoietin had higher mean hematocrit levels. Conventional magnetic resonance imaging at TEA for 100 infants showed no significant differences in global or regional brain injury scores. CONCLUSIONS AND RELEVANCE This preliminary report of a randomized clinical trial found no evidence that high-dose erythropoietin in preterm infants with IVH affects brain injury scores on conventional magnetic resonance imaging at TEA. Higher mortality in the erythropoietin group was not significant but should be reassessed based on future results from similar trials. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02076373.

Abstract
OBJECTIVE We examined whether erythropoietin monotherapy improves neurodevelopmental outcomes in near-term and term infants with neonatal encephalopathy (NE) in low-middle income countries (LMICs). METHODS We searched Pubmed, Embase, and Web of Science databases to identify studies that used erythropoietin (1500-12,500 units/kg/dose) or a derivative to treat NE. RESULTS Five studies, with a total of 348 infants in LMICs, were retrieved. However, only three of the five studies met the primary outcome of death or neuro-disability at 18 months of age or later. Erythropoietin reduced the risk of death (during the neonatal period and at follow-up) or neuro-disability at 18 months or later (p < 0.05). Death or neuro-disability occurred in 27.6% of the erythropoietin group and 49.7% of the comparison group (risk ratio 0.56 (95% CI: 0.42-0.75)). CONCLUSION The pooled data suggest that erythropoietin monotherapy may improve outcomes after NE in LMICs where therapeutic hypothermia is not available.
