[PMID: 39937316 PMCID: PMC11821745 DOI: 10.1007/s00431-025-06013-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2024] [Revised: 01/19/2025] [Accepted: 01/28/2025] [Indexed: 02/13/2025]
Abstract
To describe outcomes of a cohort of patients with paediatric acute liver failure (PALF) treated with either one of two extracorporeal therapies (ECT) - continuous renal replacement therapy (CRRT) and molecular adsorbent recirculatory system (MARS®). Retrospective, observational, cohort study at two European paediatric intensive care units (PICUs) - UK (2006-2017, CRRT) and the Netherlands (2003-2017, MARS® and CRRT). Patients were children (0-18 years) admitted to the PICU with PALF who required CRRT or MARS®. Between each group, we compared baseline characteristics, biochemical parameters at 0 and 24 h after commencing MARS®/CRRT, and clinical outcomes. In total, 95 patients (23 MARS®, 72 CRRT) were included. The median age at admission for the whole cohort was 4.3 years (interquartile range (IQR) 1.0-12.1), and 47/95 (49.5%) of patients had an indeterminate aetiology. A lower proportion of patients in the MARS® group were on inotropes or were ventilated at admission, and they had a lower Pediatric Index of Mortality 3 risk % than the CRRT group (14.5% (7.5-22) vs 20.4% (16.8-26.4), p = 0.002). After treatment, there were no significant differences detected between groups in survival with native liver, or overall survival (15/23 (65.2%) for MARS® and 49/72 (68.1%) for CRRT, p = 0.998). CONCLUSION We did not detect a significant difference in clinical outcomes between PALF patients treated with CRRT or MARS®, despite a relatively sicker cohort in the CRRT group. Further high-quality evidence is necessary regarding the role of extracorporeal therapies in PALF, with consideration of clinical outcomes, feasibility, and cost. WHAT IS KNOWN • Outcomes for children with paediatric acute liver failure (PALF) have improved in recent years secondary to improved supportive care aimed at avoiding liver transplantation. • Extracorporeal therapies, in particular continuous renal replacement therapy (CRRT), are increasingly applied in the management of these children; however few studies have compared outcomes between different extracorporeal therapies. WHAT IS NEW • In this retrospective study across two centres, outcomes between patients with PALF treated with CRRT were compared to patients treated with MARS®. • There was no significant difference in key clinical outcomes between groups, including survival with native liver and overall survival.

Abstract
BACKGROUND/AIMS Acute liver injury is a common manifestation of parvovirus B19 (PVB19) infection in immunocompromised patients. However, literature in immunocompetent children is scarce. We aimed to study the clinicolaboratory features and outcome of hepatic involvement by PVB19 infection in hospitalized children. METHODS We retrospectively analyzed our prospectively kept database of all children (<18 years old) admitted with acute viral hepatitis (AVH), acute liver failure (ALF) or acute-on-chronic liver failure (ACLF), and PVB19 infection between January 2010 and December 2023. Clinical features, laboratory parameters, and complications were evaluated. Poor outcome was defined as death or liver transplantation. RESULTS A total of 35 children (19 boys [54%], median age: 7.25 [interquartile range: 4-10.8] years) with PVB19-related hepatitis were studied (28 [80%] isolated PVB19 infection and 7 [20%] coinfections [3 with Epstein-Barr virus, 2 with hepatitis A, and 1 each with hepatitis-E and cytomegalovirus]). AVH (17, 49%) was the most common presentation, followed by ALF (13, 37%) and acute insult in ACLF (5, 14%). Patients with coinfection had significantly higher bilirubin (14.6 [9.4-21.5] vs 6.8 [4.3-10.9] mg/dl; P=0.004) and transaminases (ALT: 697 [428-1296] vs. 277 [157-478] U/L; P=0.02) but similar mortality (1/7 vs 6/23; P=1.0) than PVB19 alone. Nine cases (25.7%) had extrahepatic complications (hemophagocytic lymphohistiocytosis [HLH]: 3, acute kidney injury: 3, aplastic anemia: 2, and myocarditis: 1). Poor outcome occurred in 38% (5/13) ALF, 11.7% (2/17) AVH (HLH: 1, myocarditis: 1), and none (0/5) of the ACLF cases. CONCLUSION PVB19 should be considered in children presenting with indeterminate acute liver injury, especially in younger children or those with complications such as aplastic anemia, HLH, or myocarditis.

J Inherit Metab Dis 2025; 48:e12707. [PMID: 38279772 PMCID: PMC11726157 DOI: 10.1002/jimd.12707] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 12/11/2023] [Accepted: 12/13/2023] [Indexed: 01/28/2024]
Abstract
Among genetic disorders of vesicular trafficking, there are three causing recurrent acute liver failure (RALF): NBAS, RINT1, and SCYL1-associated disease. These three disorders are characterized by liver crises triggered by febrile infections and account for a relevant proportion of RALF causes. While the frequency and severity of liver crises in NBAS and RINT1-associated disease decrease with age, patients with SCYL1 variants present with a progressive, cholestatic course. In all three diseases, there is a multisystemic, partially overlapping phenotype with variable expression, including liver, skeletal, and nervous systems, all organ systems with high secretory activity. There are no specific biomarkers for these diseases, and whole exome sequencing should be performed in patients with RALF of unknown etiology. NBAS, SCYL1, and RINT1 are involved in antegrade and retrograde vesicular trafficking. Pathomechanisms remain unclarified, but there is evidence of a decrease in concentration and stability of the protein primarily affected by the respective gene defect and its interaction partners, potentially causing impairment of vesicular transport. The impairment of protein secretion by compromised antegrade transport provides a possible explanation for different organ manifestations such as bone alteration due to lack of collagens or diabetes mellitus when insulin secretion is affected. Dysfunction of retrograde transport impairs membrane recycling and autophagy. The impairment of vesicular trafficking results in increased endoplasmic reticulum stress, which, in hepatocytes, can progress to hepatocytolysis. While there is no curative therapy, an early and consequent implementation of an emergency protocol seems crucial for optimal therapeutic management.

Paediatric acute liver failure: a multidisciplinary perspective on when a critically ill child is unsuitable for liver transplantation. THE LANCET. CHILD & ADOLESCENT HEALTH 2024; 8:921-932. [PMID: 39572125 DOI: 10.1016/s2352-4642(24)00255-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2024] [Revised: 09/02/2024] [Accepted: 09/09/2024] [Indexed: 12/11/2024]
Abstract
Paediatric acute liver failure is a devastating condition with high morbidity and mortality, which is challenging to manage for the hepatologist, intensivist, and associated specialists. Emergency liver transplantation is required for 10-20% of patients, but for 10% of critically ill children, liver transplantation is deemed unsuitable; the child might be too unwell, or the underlying cause might carry a poor prognosis. Other social, logistical, or ethical considerations are often relevant. Liver transplantation when a patient is too unwell creates perioperative risk to the child that could lead to morbidity, mortality, and potential graft wastage, which is detrimental for others on the waiting list. Donor liver scarcity should prompt an evaluation of whether a transplant is justified through a holistic multidisciplinary lens that considers medical, social, logistical, and ethical concerns. In this Review, we explore, from a multidisciplinary perspective, why a critically unwell child with paediatric acute liver failure might be unsuitable for liver transplantation.

Abstract
Understanding the economics of pediatric liver transplantation (LT) is central to high-value care initiatives. We examined cost and resource utilization in pediatric LT nationally to identify drivers of cost and hospital factors associated with greater total cost of care. We reviewed 3295 children (<21 y) receiving an LT from 2010 to 2020 in the Pediatric Health Information System to study cost, both per LT and service line, and associated mortality, complications, and resource utilization. To facilitate comparisons, patients were stratified into high-cost, intermediate-cost, or low-cost tertiles based on LT cost. The median cost per LT was $150,836 [IQR $104,481-$250,129], with marked variance in cost within and between hospital tertiles. High-cost hospitals (HCHs) cared for more patients with the highest severity of illness and mortality risk levels (67% and 29%, respectively), compared to intermediate-cost (60%, 21%; p <0.001) and low-cost (51%, 16%; p <0.001) hospitals. Patients at HCHs experienced a higher prevalence of mechanical ventilation, total parental nutrition use, renal comorbidities, and surgical complications than other tertiles. Clinical (27.5%), laboratory (15.1%), and pharmacy (11.9%) service lines contributed most to the total cost. Renal comorbidities ($69,563) and total parental nutrition use ($33,192) were large, independent contributors to total cost, irrespective of the cost tertile ( p <0.001). There exists a significant variation in pediatric LT cost, with HCHs caring for more patients with higher illness acuity and resource needs. Studies are needed to examine drivers of cost and associated outcomes more granularly, with the goal of defining value and standardizing care. Such efforts may uniquely benefit the sicker patients requiring the strategic resources located within HCHs to achieve the best outcomes.

Abstract
OBJECTIVES Our aim was to determine the prevalence and explanatory factors associated with outcomes in children with acute liver failure (ALF) admitted to the PICU, who also develop severe acute kidney injury (AKI). DESIGN Retrospective cohort, 2003 to 2017. SETTING Sixteen-bed PICU in a university-affiliated tertiary care hospital. PATIENTS Admissions to the PICU with ALF underwent data review of the first week and at least 90-day follow-up. Patients with stages 2-3 AKI using the British Association of pediatric Nephrology definitions, or receiving continuous renal replacement therapy (CRRT) for renal indications, were defined as severe AKI. We excluded ALF cases on CRRT for hepatic-only indications. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Baseline characteristics, proportion with severe AKI, illness severity and interventions, and outcomes (i.e., transplant, survival with native liver, overall survival, duration of PICU stay, and mechanical ventilation). Ninety-four children with ALF admitted to the PICU were included. Over the first week, 29 had severe AKI, and another eight received CRRT for renal/mixed reno-hepatic indications; hence, the total severe AKI cohort was 37 of 94 (39.4%). In a multivariable logistic regression model, peak aspartate aminotransferase (AST) and requirement for inotropes on arrival were associated with severe AKI. Severe AKI was associated with longer PICU stay and duration of ventilation, and lower spontaneous survival with native liver. In another model, severe AKI was associated with greater odds of mortality (odds ratio 7.34 [95% CI, 1.90-28.28], p = 0.004). After 90 days, 3 of 17 survivors of severe AKI had serum creatinine greater than the upper limit of normal for age. CONCLUSIONS Many children with ALF in the PICU develop severe AKI. Severe AKI is associated with the timecourse of PICU admission and outcome, including survival with native liver. Future work should look at ALF goal directed renoprotective strategies at the time of presentation.

Abstract
Abstract
Background
Acute liver failure (ALF) is a serious condition that refers to the development of synthetic function impairment after severe acute liver injury in an individual without pre-existing liver disease. Understanding the epidemiology of ALF in children constitutes a cornerstone in its preventive and treatment plans. Nevertheless, there is a lack of information about its epidemiology in Egypt.
Objective
The aim of this study was to assess the epidemiologic data of ALF in Egyptian children.
Patients and methods
The medical records of children with ALF aged from 6 months to 18 years who were admitted from 2015 to 2020 were analyzed to identify the patient’s epidemiologic, laboratory, and investigational data together with their outcome.
Results
The study included 154 patients who fulfilled the definition of ALF were included. Their age ranged from 7 months to 17 years, with a median of 5.8 years. Hepatitis A virus (HAV) was the most commonly identifiable etiology (37.7%). Mortality was the outcome for 73 patients (47.4%). The prognostic factors associated with mortality were elevated international normalized ratio (INR), total bilirubin (TB), creatinine, and ammonia levels at presentation with cutoff values (2.97, 21.15, 0.385, and 212, respectively).
Conclusion
Hepatitis A virus is the most commonly identified etiology of ALF in Egyptian children. The mortality rate is high, and most of the deaths occurred early in the first 5 days of admission. So, early preparation for liver transplantation is recommended. Higher values of INR, TB, and creatinine above the cutoff levels at presentation may be potential markers for predicting death in affected children.

Abstract
BACKGROUND Intraoperative Continuous Renal Replacement Therapy (iCRRT) can prevent life-threatening complications, facilitate fluid management, and maintain metabolic homeostasis during liver transplantation (LT) in adults. There is a paucity of data in pediatric LT. We evaluated the safety, efficacy, and impact on survival of iCRRT in pediatric LT. METHODS We conducted a retrospective cohort study of all children requiring CRRT pre-OLT at a quaternary children's hospital from 2014 to 2022. Demographic characteristics, intraoperative events, and post-LT outcomes were compared between those who received iCRRT and those who did not. RESULTS Out of 306 patients who received LT, 30 (10%) were supported with CRRT at least 24 h prior to LT, of which 11 (36%) received iCRRT. The two cohorts were similar in demographics, diagnosis of liver disease, and severity of illness. The iCRRT patients experienced massive blood loss and increased transfusion requirements. There was no difference in intraoperative metabolic balance. One-year post-LT mortality rates were similar. CONCLUSION ICRRT is safe in critically ill children with pre-LT renal dysfunction. It optimizes fluid and blood product resuscitation while maintaining metabolic homeostasis. Candidates need to be carefully chosen for this highly resource-intensive therapy to benefit this fragile population.

Abstract
INTRODUCTION Acetaminophen (APAP) toxicity remains a significant cause of adult and pediatric liver failure in North America and Europe. Previous research has evaluated the impaired mitochondrial function associated with APAP toxicity. The primary aim of this study was to evaluate the effects of APAP toxicity on platelet mitochondrial function using platelet oxygen consumption in a murine model in vivo. Our secondary objectives were to determine the effect of 4-MP on platelet mitochondrial function and hepatic toxicity in the setting of APAP overdose, and to correlate platelet mitochondrial function with other markers of APAP toxicity. METHODS Male C57Bl/6 mice were randomized to receive APAP (300 or 500 mg/kg) or vehicle followed 90 minutes later by either 4-MP (50 mg/kg) or vehicle via intraperitoneal injection. Mice were euthanized 0, 12, or 24 hours later and platelets isolated from cardiac blood and counted. Platelet oxygen consumption (POC) was determined using a closed-system respirometer. Liver injury was assessed by measuring alanine transferase (ALT) and histological evaluation. RESULTS Injection of 500 mg/kg APAP led to increased POC versus pair-matched control (vehicle) (p < 0.001). Administration of 4-MP did not affect POC in control or 300 mg/kg APAP mice. In mice receiving 500 mg/kg APAP and 4-MP, POC decreased significantly compared to mice receiving 500 mg/kg APAP alone (p < 0.01). Serum and histological analysis confirmed APAP-induced hepatic damage in mice receiving 500 mg/kg APAP and these effects blunted by treatment with 4-MP. CONCLUSIONS Platelet oxygen consumption as a measure of mitochondrial function may be useful as a biomarker of hepatic APAP toxicity in the setting of moderate to severe overdose. Treatment with 4-MP decreases hepatic necrosis and may mitigate the harmful effects of APAP on platelet mitochondrial function detected via POC.

Abstract
Acetaminophen overdose is common in the pediatric population. N-acetylcysteine (NAC) is effective at preventing liver injury in most patients when started shortly after the overdose. Delays to therapy increase risk of hepatotoxicity and liver failure that may necessitate organ transplant. Animal studies have demonstrated fomepizole may provide added benefit in acetaminophen overdose because of its ability to block the metabolic pathway that produces the toxic acetaminophen metabolite and downstream inhibition of oxidative stress pathways that lead to cell death. Several adult case reports describe use of fomepizole in patients at higher risk for poor outcomes despite NAC. We describe a case of a 7-month-old female who presented in acute liver failure with persistently elevated acetaminophen concentration secondary to repeated supratherapeutic doses of acetaminophen to manage fever. Fomepizole and NAC antidotes were used in the management of the patient. She fully recovered despite demonstrating multiple markers of poor outcome on initial presentation. Although randomized trials are lacking, this case suggests that fomepizole may safely provide additional benefit in pediatric patients at risk for severe acetaminophen toxicity.

Abstract
OBJECTIVES The objectives of this study was to describe variation in induction regimen, identify predictors of induction immunosuppression (IS) choice, and examine the impact of induction IS regimen on length of stay (LOS) and total perioperative costs in pediatric liver transplant recipients. METHODS We analyzed liver transplant utilization data in the Pediatric Health Information System database. Patients were divided into 3 induction IS groups: (1) steroids only, (2) T-cell depleting antibody (TDA), and (3) non-TDA. We identified predictors of induction IS regimen and examined associations between each outcome and choice of induction IS. RESULTS We analyzed 4905 liver transplant recipients (50% female, 80% under age 13 years, 42% non-Hispanic White). Most patients (3162, 64%) received steroids only induction, and about twice as many patients received a non-TDA regimen (1093, 22%) versus a TDA regimen (650, 13%). Median total perioperative costs were highest for the TDA group [$146,438 (interquartile range $113,461-$195,575)] versus the non-TDA group [$129,307 ($102,632-$173,953)] and the steroids only group ($127,049 ($98,814-$181,053)]. Compared to steroids only induction, TDA was associated with increased LOS (+2 days, P = 0.017) with no difference in cost. Non-TDA induction was associated with a decreased LOS (-3 days, P < 0.001) and increased cost (+$42,542; P < 0.001) independent of LOS. CONCLUSIONS Compared to a steroids only induction IS regimen, non-TDA induction was associated with increased total perioperative costs, even after adjustments for LOS. Future work will combine cost and outcome data to provide decision-making support in pediatric liver transplant recipients.

Abstract
OBJECTIVE The objective of this study was to determine the etiologies, outcomes, prognostic indicators and the role of genetic testing in children with acute liver failure (ALF). METHODS This retrospective study included 46 patients with pediatric acute liver failure (PALF) according to the PALF study group definition, admitted to King Fahad Specialist Hospital-Dammam, Saudi Arabia, between January 2014 and December 2021. Patients who survived with supportive therapy were designated as the recovery group, whereas those who died or underwent liver transplantation were designated as the death/transplant group. RESULTS There were 26 (56.5%) patients in the recovery group and 20 (43.5%) patients in the death/transplant group. Four patients (8.7%) underwent liver transplantation. After indeterminate causes (45.6%), genetic-metabolic diseases and drug-induced liver injury (DILI) were the most common cause with 15.2 and 13%, respectively. Genetic testing had a high yield of (6/31) in identifying monogenic disease associated with ALF. Younger age, lower Glasgow Coma Scale and higher international normalized ratio (INR) on admission were predictors for poor prognosis. The death/transplant group had longer intensive care unit stay ( P < 0.001), and on admission they had more advanced hepatic encephalopathy ( P < 0.005), more prolonged prothrombin time ( P < 0.001), higher lactate ( P < 0.006), higher total and direct bilirubin ( P < 0.008) and ( P < 0.001), respectively. CONCLUSION Genetic, metabolic and DILI causes constituted the most common cause of PALF after indeterminate causes. The use of genetic testing can improve diagnostic rates in special cases, but we could not assess the effect of genetic testing on prognosis. The overall survival rate in our study was 65.2%. Younger age, higher admission INR and lower Glasgow coma scale were indicators of poor prognosis.

Abstract
BACKGROUND Acute kidney injury (AKI) is common in pediatric patients undergoing liver transplantation (LT), with an incidence 17%-55%. Fluid, metabolic, and acid-base aberrancies are often pronounced pre-operatively and further worsened by events during LT, making intra-operative continuous renal replacement therapy (CRRT) an option for critically ill LT recipients. METHODS All pediatric LT performed at our institution who underwent intra-operative CRRT between January 2017 and August 2021 were included. Patient demographics and clinical data including graft outcomes, intra-operative findings, and timing and indications for CRRT were collected from the electronic medical record. RESULTS CRRT was used in nine of the 76 (12%) pediatric LT performed at our center during the study period. Ages at LT ranged from 39 to 17.7 years. Recipients requiring CRRT were more likely to have acute liver failure, status 1A, and higher calculated MELD/PELD scores. CRRT was initiated pre-transplant in three recipients and continued post-transplant in six recipients. Median duration of CRRT was two (range 0-14) days. Indications included hyperammonemia (3/9), acidosis (3/9), fluid overload (6/9), and hyperkalemia (2/9). The CRRT group had a significantly longer post-transplant intensive care unit length of stay in comparison to those that did not require CRRT (median 6, range 3-40 days vs. median 3, range 0-121 days, p = .02], but there were no significant differences in reoperations, hospital length of stay, or recipient or graft survival. CONCLUSIONS We demonstrate that CRRT can be safely performed in pediatric LT recipients, including young infants through adolescents.

Abstract
Importance After a cluster of pediatric cases of hepatitis of unknown etiology were identified in Scotland in March 2022, the World Health Organization published an outbreak alert, and more than 1010 probable cases were reported. Some cases progressed to acute liver failure and required liver transplant. Although many patients had positive results for adenovirus on polymerase chain reaction testing from whole blood samples and/or reported recent COVID-19 infection (with or without seropositivity), the precise pathogenesis remains unclear despite the high potential morbidity of this condition. Objective To summarize the currently available evidence regarding novel pediatric hepatitis of unknown etiology (or novel hepatitis), encompassing case numbers, testing, management, and outcomes. Evidence Review A rapid review of the literature from April 1, 2021, to August 30, 2022, aimed to identify all available published case series and case-control studies of novel hepatitis. The search included PubMed and references and citations of short-listed studies. Findings A total of 22 available case series and case-control studies describing 1643 cases were identified, with 120 children (7.3%) receiving liver transplants and 24 deaths (1.5%). Outcome reporting and testing for adenovirus and SARS-CoV-2 was incomplete. Assessment of disease severity and management was mixed and results regarding testing for adenovirus and SARS-CoV-2 were inconsistent for both serological testing and testing of explant or biopsy liver samples. More recent studies suggest a more plausible role for adenovirus and/or adeno-associated virus 2. Conclusions and Relevance This systematic review without meta-analysis describes the challenge posed by hepatitis of unknown etiology in terms of investigation and management, with many cases progressing to acute liver failure. The lack of clarity regarding pathogenesis means that these children may be missing the potential for targeted therapies to improve outcomes and avert the need for transplant. Clinicians, immunologists, and epidemiologists must collaborate to investigate the pathogenesis of this novel hepatitis.

Abstract
Paediatric acute liver failure (PALF) is defined as a biochemical evidence of acute liver injury in a child with no previous history of chronic liver disease characterised by an international normalised ratio (INR) of 1·5 or more unresponsive to vitamin K with encephalopathy, or INR of 2·0 or more with or without encephalopathy. PALF can rapidly progress to multiorgan dysfunction or failure. Although the transplant era has substantially changed the outlook for these patients, transplantation itself is not without risks, including those associated with life-long immunosuppression. Consequently, there has been an increased focus on improving medical management to prioritise bridging of patients to native liver survival, which is possible due to improved understanding of the underlying pathophysiology of multiorgan involvement in PALF. In this Review, we discuss recent advances in the medical management of PALF with an aim of reducing the need for liver transplantation. The Review will focus on the non-specific immune-mediated inflammatory response, extracorporeal support devices, neuromonitoring and neuroprotection, and emerging cellular and novel future therapeutic options.

Abstract
OBJECTIVE Outcome of pediatric acute liver failure (PALF) in countries with limited availability of LT is not well described. We evaluated the outcome and prognostic indicators of PALF in Malaysia where emergency LT for ALF is limited. METHODS In this retrospective review on children < 18 years with PALF, we compared clinical and laboratory parameters between survival after supportive treatment and after LT or succumbed without LT. The predictive values of Liver Injury Unit (LIU; peak laboratory values for international normalized ratio [INR], ammonia, total bilirubin) and upon admission (aLIU) on outcome of PALF was evaluated using receiver operator characteristic (ROC) curves. RESULTS Of 77 children (39 males [51%]; median age 2.8 years) with PALF, the overall survival was 55% (n = 42); 52% (n = 40) survived with supportive management, 2.6% (n = 2) after LT. As compared to children who survived without LT, children who had LT/died had lower hemoglobin, aspartate transferase, γ-glutamyl transpeptidase (GGT), and higher serum bilirubin, alkaline phosphatase, ammonia, and serum sodium (p < 0.05). On multivariate analysis, significant independent predictor for death or LT were peak bilirubin > 452 μmol/L and peak GGT < 96 IU/L. The C-index of LIU and aLIU score were 0.79 and 0.68, respectively, indicating that LIU score was a good model in predicting outcome of PALF. CONCLUSIONS Overall survival of PALF remained poor. High peak bilirubin and low GGT predict poor outcome of PALF. LIU score is a good model in predicting outcome of PALF and maybe useful in selecting children for emergency LT.

Abstract
Paediatric acute liver failure (PALF) is a rare but devastating condition with high mortality. An exaggerated inflammatory response is now recognised as pivotal in the pathogenesis and prognosis of ALF, with cytokine spill from the liver to systemic circulation implicated in development of multi-organ failure associated with ALF. With advances in medical management, especially critical care, there is an increasing trend towards spontaneous liver regeneration, averting the need for emergency liver transplantation or providing stability to the patient awaiting a graft. Hence, research is ongoing for therapies, including extracorporeal liver support devices, that can bridge patients to transplant or spontaneous liver recovery. Considering the immune-related pathogenesis and inflammatory phenotype of ALF, plasma exchange serves as an ideal liver assist device as it performs both the excretory and synthetic functions of the liver and, in addition, works as an immunomodulatory therapy by suppressing the early innate immune response in ALF. After a recent randomised controlled trial in adults demonstrated a beneficial effect of high-volume plasma exchange on clinical outcomes, this therapy was incorporated in European Association for the Study of Liver (EASL) recommendations for managing adult patients with ALF, but no guidelines exist for PALF. In this review, we discuss rationale, timing, practicalities, and existing evidence regarding the use of plasma exchange as an immunomodulatory treatment in PALF. We discuss controversies in delivery of this therapy as an extracorporeal device, and practicalities of use of plasma exchange as a 'hybrid' therapy alongside other extracorporeal liver assist devices, before finally reviewing outstanding research questions for the future.

Abstract
OBJECTIVE To characterize a multi-institutional cohort of pediatric patients who underwent colectomy for familial adenomatous polyposis (FAP). STUDY DESIGN In this retrospective cohort study, diagnosis and procedure codes were used to identify patients who underwent colectomy for FAP within the Pediatric Health Information System (PHIS). The inclusion criteria were validated at 3 children's hospitals and applied to PHIS to generate a cohort of patients with FAP between 2 and 21 years who had undergone colectomy between 2009 and 2019. Demographics, clinical and surgical characteristics, and endoscopic procedure trends as identified through PHIS are described. Descriptive and comparative statistics were used to analyze data. RESULTS Within the PHIS, 428 pediatric patients with FAP who underwent colectomy were identified. Median age at colectomy was 14 years (range 2-21 years); 264 patients (62%) received an ileal pouch anal anastomosis and 13 (3%) underwent ileorectal anastomosis. Specific anastomotic surgical procedure codes were not reported for 151 patients (35%). Endoscopic assessment at the surgical institution occurred in 40% of the cohort before colectomy and in 22% of the cohort following colectomy. CONCLUSIONS In this cohort, colectomy took place at an earlier age than suggested in published guidelines. Ileal pouch anal anastomosis is the predominant procedure for pediatric patients with FAP who underwent colectomy in US pediatric centers. Endoscopic assessment trends before and after surgery suggest that the surgical institution plays a limited role in the care of this population.

Abstract
ABSTRACT Pediatric acute liver failure (PALF) is a rare, rapidly progressive clinical syndrome with significant morbidity and mortality. The phenotype of PALF manifests as abrupt onset liver dysfunction, which can be brought via disparate etiology. Management is reliant upon intensive clinical care and support, often provided by the collaborative efforts of hepatologists, critical care specialists, and liver transplant surgeons. The construction of an age-based diagnostic approach, the identification of a potential underlying cause, and the prompt implementation of appropriate therapy can be lifesaving; however, the dynamic and rapidly progressive nature of PALF also demands that diagnostic inquiries be paired with monitoring strategies for the recognition and treatment of common complications of PALF. Although liver transplantation can provide a potential life-saving therapeutic option, the ability to confidently determine the certainness that liver transplant is needed for an individual child has been hampered by a lack of adequately tested clinical decision support tools and accurate predictive models. Given the accelerated progress in understanding PALF, we will provide clinical guidance to pediatric gastroenterologists and other pediatric providers caring for children with PALF by presenting the most recent advances in diagnosis, management, pathophysiology, and associated outcomes.

Pediatric acute liver failure: An experience of a pediatric intensive care unit from resource limited settings. Front Pediatr 2022; 10:956699. [PMID: 36120651 PMCID: PMC9478462 DOI: 10.3389/fped.2022.956699] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Accepted: 08/12/2022] [Indexed: 12/02/2022] Open
Abstract
INTRODUCTION Pediatric acute liver failure is a rare and serious disease. Though liver transplantation is considered as the established treatment option for patients who are unlikely to recover with medical management, however, with the advancement of medical care there has been an increase in spontaneous regeneration of liver, obviating the need for liver transplantation. We identified the etiologies, outcome and prognostic factors of acute liver failure and the validity of the existing liver transplantation criteria to predict the outcome of pediatric acute liver failure. MATERIALS AND METHODS This was a retrospective study done from January 2014 to December 2019 in a tertiary pediatric critical care unit in South India. All children aged between 1 month to 18 years admitted with acute liver failure were enrolled. RESULTS Of 125 children with acute liver failure, the main etiologies were infections (32%), indeterminate (23%), paracetamol toxicity (21%), metabolic (13%) and others (11%). Dengue was the most common infection (55%). The median pediatric logistic organ dysfunction score at admission was 12 (4-27). Of 125 patients, 63.2% (n = 79) had spontaneous regeneration which was higher in paracetamol induced (92.3%) compared to non-paracetamol induced acute liver failure (55.5%). Only two patients underwent liver transplantation and 35% died. Peak alanine transaminase and use of inotropes significantly predicted the outcome of disease. Of 38 children meeting King's College Hospital criteria for liver transplantation, 57.9% had spontaneous regeneration and 36.8% died. Of 74 children meeting INR > 4 criteria, 54% (n = 40) had spontaneous regeneration and 43.2% died. INR >4 criteria was more sensitive than King's College Hospital criteria for predicting the need for liver transplantation. CONCLUSION Pediatric acute liver failure is caused by varied etiologies and infections were the commonest cause. Despite having a seriously ill cohort of patients, medical management resulted in spontaneous regeneration in the majority of children with acute liver failure. The use of inotropes, advanced hepatic encephalopathy, and peak alanine transaminase were predictors of poor outcome in children with acute liver failure and these patients could be considered for liver transplantation as available. Therefore, we may need to develop better predictors of pediatric acute liver failure in resource limited settings.

Abstract
Liver disease results in approximately 15,000 pediatric hospitalizations per year in the United States and is a significant burden to child health. Major etiologies of liver failure and indications for transplantation in children include: biliary atresia, metabolic/genetic conditions, toxins, infections, tumors, and immune-mediated liver/biliary injury. Children requiring transplantation are placed on the United Network of Organ Sharing waitlist including those with acute liver failure (ALF) and acute on chronic liver failure (ACLF). ALF is a clinical syndrome in which a previously healthy child develops rapid-onset hepatic dysfunction, and becomes critically ill with multiple organ dysfunction within days. ACLF, by contrast, is generally described as an acute decompensation of pre-existing chronic liver disease (CLD) brought on by a precipitating event, with higher risk of mortality. Children with ALF and ACLF receive multidisciplinary care in pediatric intensive care units (ICUs) due to multiple organ system involvement and high risk of decompensation in these patients. The care of these patients requires a holistic approach that addresses the complex interplay between hepatic and extra-hepatic organ systems. This review will define and describe ALF and ACLF in the pediatric population, and outline the effects of ALF and ACLF on individual organ systems with diagnostic and management considerations in the ICU while awaiting liver transplantation.

Abstract
Management of acute liver failure (ALF) and acute on chronic liver failure (ACLF) in the pediatric population can be challenging. Kidney manifestations of liver failure, such as hepatorenal syndrome (HRS) and acute kidney injury (AKI), are increasingly prevalent and may portend a poor prognosis. The overall incidence of AKI in children with ALF has not been well-established, partially due to the difficulty of precisely estimating kidney function in these patients. The true incidence of AKI in pediatric patients may still be underestimated due to decreased creatinine production in patients with advanced liver dysfunction and those with critical conditions including shock and cardiovascular compromise with poor kidney perfusion. Current treatment for kidney dysfunction secondary to liver failure include conservative management, intravenous fluids, and kidney replacement therapy (KRT). Despite the paucity of evidence-based recommendations concerning the application of KRT in children with kidney dysfunction in the setting of ALF, expert clinical opinions have been evaluated regarding the optimal modalities and timing of KRT, dialysis/replacement solutions, blood and dialysate flow rates and dialysis dose, and anticoagulation methods.

Abstract
BACKGROUND We sought to identify factors that are associated with LOS following pediatric (<18 years) liver transplantation in order to provide personalized counseling and discharge planning for recipients and their families. METHODS We identified 2726 infants (≤24 months) and 3210 children (>24 months) who underwent pediatric liver-only transplantation from 2002-2017 using the Scientific Registry of Transplant Recipients. We used multilevel multivariable negative binomial regression to analyze associations between LOS and recipient and donor characteristics and calculated the MLOSR to quantify heterogeneity in LOS across centers. RESULTS In infants, the median LOS (IQR) was 19 (13-32) days. Hospitalization prior to transplant (ICU ratio:1.46 1.591.70 ; non-ICU ratio:1.08 1.161.23 ), public insurance (ratio:1.03 1.091.15 ), and a segmental graft (ratio:1.08 1.151.22 ) were associated with a longer LOS; thus, we would expect a 1.59-fold longer LOS in an infant admitted to the ICU compared to a non-hospitalized infant with similar characteristics. In children, the median LOS (IQR) was 13 (9-21) days. Hospitalization prior to transplant (ICU ratio:1.49 1.621.77 ; non-ICU ratio:1.34 1.441.56 ), public insurance (ratio:1.02 1.071.13 ), a segmental graft (ratio:1.20 1.271.35 ), a living donor graft (ratio:1.27 1.381.51 ), and obesity (ratio:1.03 1.101.17 ) were associated with a longer LOS. The MLOSR was 1.25 in infants and 1.26 in children, meaning if an infant received a transplant at another center with a longer LOS, we would expect a 1.25-fold difference in LOS driven by center practices alone. CONCLUSIONS While center-level practices account for substantial variation in LOS, consideration of donor and recipient factors can help clinicians provide more personalized counseling for families of pediatric liver transplant candidates.

Alginate microencapsulated human hepatocytes for the treatment of acute liver failure in children. J Hepatol 2020; 72:877-884.

Abstract
BACKGROUND & AIMS Liver transplantation (LT) is the most effective treatment for patients with acute liver failure (ALF), but is limited by surgical risks and the need for life-long immunosuppression. Transplantation of microencapsulated human hepatocytes in alginate is an attractive option over whole liver replacement. The safety and efficacy of hepatocyte microbead transplantation have been shown in animal models. We report our experience of this therapy in children with ALF treated on a named-patient basis. METHODS Clinical grade human hepatocyte microbeads (HMBs) and empty microbeads were tested in immunocompetent healthy rats. Subsequently, 8 children with ALF, who were awaiting a suitable allograft for LT, received intraperitoneal transplantation of HMBs. We monitored complications of the procedure, assessing the host immune response and residual function of the retrieved HMBs, either after spontaneous native liver regeneration or at the time of LT. RESULTS Intraperitoneal transplantation of HMBs in healthy rats was safe and preserved synthetic and detoxification functions, without the need for immunosuppression. Subsequently, 8 children with ALF received HMBs (4 neonatal haemochromatosis, 2 viral infections and 2 children with unknown cause at time of infusion) at a median age of 14.5 days, range 1 day to 6 years. The procedure was well tolerated without complications. Of the 8 children, 4 avoided LT while 3 were successfully bridged to LT following the intervention. HMBs retrieved after infusions (at the time of LT) were structurally intact, free of host cell adherence and contained viable hepatocytes with preserved functions. CONCLUSION The results demonstrate the feasibility and safety of an HMB infusion in children with ALF. LAY SUMMARY Acute liver failure in children is a rare but devastating condition. Liver transplantation is the most effective treatment, but it has several important limitations. Liver cell (hepatocyte) transplantation is an attractive option, as many patients only require short-term liver support while their own liver recovers. Human hepatocytes encapsulated in alginate beads can perform the functions of the liver while alginate coating protects the cells from immune attack. Herein, we demonstrated that transplantation of these beads was safe and feasible in children with acute liver failure.

Abstract
Evaluation for liver transplant candidacy is a multidisciplinary effort that involves all aspects of clinical care including social work, nutrition, and a multitude of medical specialties. The prognosis of a pretransplant clinical condition is integrated into the decision to list a patient. Herein, we report a successful liver transplant and recovery of a 3-month-old male following a large right hemispheric subdural hematoma related to acute coagulopathy secondary to undiagnosed end-stage liver disease. On presentation with jaundice, lethargy, and unequal pupils, a CT scan was obtained which demonstrated a large right subdural hematoma with herniation. Once his coagulopathy was corrected, he went for decompressive craniectomy. He survived with medically controlled seizures and improving L-sided neglect and extremity weakness. Six weeks later, given his continued neurologic recovery and worsening liver function, the decision was made to list him for liver transplantation. One month later, he underwent orthotopic liver transplant. His post-operative hospital course was complicated by DVTs and heparin-induced thrombocytopenia, but no neurologic decline, and he was eventually discharged from the hospital on post-op day 26. Three years later, he has a well-functioning allograft and no clinically evident neurologic deficits. The prognosis following pediatric neurologic trauma remains somewhat unclear as recovery and neurologic examinations can be influenced by numerous extrinsic factors. This is one of the first reports of near full neurologic recovery of a pediatric liver transplant recipient following a large subdural hematoma with herniation.

Abstract
BACKGROUND Liver dysfunction is an independent risk factor for poor prognosis of patients with sepsis. The aim of this study is to evaluate the effects of continuous hemofiltration in patients with bacterial sepsis complicated by liver dysfunction. METHODS We retrospectively analyzed the medical records of 27 cases of bacterial sepsis with liver dysfunction admitted to pediatric intensive care unit (PICU) of Shanghai Children's Hospital between January 2013 and December 2016. RESULTS 28-day mortality and length of PICU stay were significantly reduced in the continuous hemofiltration group (n = 16) compared with the conventional management group (n = 11) (31.3% vs. 72.7%, 9 [4-23] vs. 14 [4-36], respectively, both P < 0.05). The interval time between PICU admission and continuous hemofiltration initiation was (22.06 ± 17.68) h, and the median time of continuous hemofiltration duration was 48 h (31-70 h). After 72 h hemofiltration, the levels of total bilirubin (TBIL), direct bilirubin (DBIL), total bile acids (TBA), ammonia, lactate (Lac), TNF-α and IL-6 were significantly decreased in the continuous hemofiltration group. Moreover, multivariate logistic regression analysis indicated that continuous hemofiltration treatment and the TBIL level were independently associated with 28-day mortality of patients with bacterial sepsis complicated by liver dysfunction. CONCLUSIONS Continuous hemofiltration significantly decreases the serum levels of TBIL, DBIL, TBA, Lac, ammonia, TNF-α, IL-6, and improves 28-day mortality of patients with bacterial sepsis complicated by liver dysfunction.

Abstract
Background Acetaminophen is a common cause of acute liver failure in pediatrics. Cerebral edema is a significant complication of acute hepatic failure and is associated with increased mortality. Case presentation We present a case of a 13 -year old girl with severe cerebral edema secondary to acetaminophen toxicity and hepatic failure. Her poor neurological status precluded her from liver transplantation and withdrawal of life sustaining treatment was recommended. However, with supportive care, she remarkably made a full recovery. Conclusions This case highlights the difficulties surrounding prognostication in pediatric patients with cerebral edema from acute liver failure secondary to acetaminophen toxicity.

Abstract
Pediatric acute liver failure is a rapidly progressive, life-threatening, and devastating illness in children without preexisting liver disease. Due to the rarity and heterogeneity of this syndrome, there is a significant lack of data to guide evaluation and management of this disease. Most of our practice is extrapolated from adult literature and guidelines. This leads to significant controversies in medical management of acute liver failure in children. With advances in critical care, there has been a tremendous improvement in outcomes with decreased morbidity and mortality; however, there is a dire need for more research in this field. This chapter discusses challenges as well as controversies in diagnostic evaluation and management of this rare but potentially fatal disease. Latest developments in supportive care of liver failure, including advances in the area of liver support systems, are also discussed.

J Pediatr 2018; 198:254-259.e1. [PMID: 29622340 DOI: 10.1016/j.jpeds.2018.02.033] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2017] [Revised: 01/18/2018] [Accepted: 02/13/2018] [Indexed: 10/17/2022]
Abstract
OBJECTIVE To assess the temporal association of flow restrictor introduction and the rate of accidental unsupervised ingestions (AUIs) of liquid acetaminophen products. STUDY DESIGN The National Poison Data System was used to identify AUIs of single ingredient acetaminophen in patients aged <12 years reported between 2007 and 2015. Six regional poison centers obtained additional information using a structured telephone survey. RESULTS Pediatric AUIs involving acetaminophen averaged 30 000 exposures per year between 2007 and 2012. From 2012 to 2015, after flow restrictor introduction, exposures steadily decreased at a rate of 2400 fewer exposures annually, reaching 21 877 exposures in 2015. Normalized to sales volume, exposures involving liquid acetaminophen products decreased by 40% from 2010 to 2015. Exposures involving products with flow restrictors tended to have a lower estimated ingestion per exposure, fewer exposures exceeding a 150 mg/kg acetaminophen threshold, and were associated with lower rates of hospital admissions when compared with products without restrictors. Caregivers reported improper storage and child confusion of the medicine with treats as common contributing factors to exposures. CONCLUSIONS The introduction of flow restrictors was associated with a decrease in pediatric AUIs of liquid acetaminophen products. Decreases in the dose ingested and risk of hospital admission per exposure may also have resulted. Efforts to optimize flow restrictors and increase their use with medicines associated with high pediatric overdose risk should be encouraged.

Abstract
BACKGROUND The objective of the study was to identify national trends in the utilization of histrelin acetate implants among transgender children in the United States. METHODS We analyzed demographic, diagnostic and treatment data from 2004 to 2016 on the use of histrelin acetate reported to the Pediatric Health Information System (PHIS) to determine the temporal trends in its use for transgender-related billing diagnoses, e.g. "gender identity disorder". Demographic and payer status data on this patient population were also collected. RESULTS Between 2004 and 2016, the annual number of implants placed for a transgender-related diagnosis increased from 0 to 63. The average age for placement was 14 years. Compared to natal females, natal males were more likely to receive implants (57 vs. 46) and more likely to have implants placed at an older age (62% of natal males vs. 50% of natal females were ≥;13 years; p<0.04). The majority of children were White non-Hispanic (White: 60, minority: 21). When compared to the distribution of patients treated for precocious puberty (White: 1428, minority: 1421), White non-Hispanic patients were more likely to be treated with a histrelin acetate implant for a transgender-related diagnosis than minority patients (p<0.001). This disparity was present even among minority patients with commercial insurance (p<0.001). CONCLUSIONS Utilization of histrelin acetate implants among transgender children has increased dramatically. Compared to natal females, natal males are more likely to receive implants and also more likely to receive implants at an older age. Treated transgender patients are more likely to be White when compared to the larger cohort of patients being treated with histrelin acetate for central precocious puberty (CPP), thus identifying a potential racial disparity in access to medically appropriate transgender care.

Abstract
Purpose of Review Pediatric acute liver failure is a rare, complex, rapidly progressing, and life-threatening illness. Majority of pediatric acute liver failures have unknown etiology. This review intends to discuss the current literature on the challenging aspects of management of acute liver failure. Recent Findings Collaborative multidisciplinary approach for management of patients with pediatric acute liver failure with upfront involvement of transplant hepatologist and critical care specialists can improve outcomes of this fatal disease. Extensive but systematic diagnostic evaluation can help to identify etiology and guide management. Early referral to a transplant center with prompt liver transplant, if indicated, can lead to improved survival in these patients. Summary Prompt identification and aggressive management of pediatric acute liver failure and related comorbidities can lead to increased transplant-free survival and improved post-transplant outcomes, thus decreasing mortality and morbidity associated with this potential fatal condition.

Abstract
Although there have been advances made in the diagnosis and management of pediatric acute liver failure, there is still no consensus regarding the definition or standardized evaluation, and an inability to predict outcomes, specifically irreversible brain injury, in many patients exists. Much of the research surrounding pediatric acute liver failure in the last several years has centered on the development of predictive scoring systems to enhance diagnosis and treatment decisions. In this article, we will discuss our current understanding of liver failure and updated management strategies in children with acute liver failure.

Abstract
Pediatric acute liver failure is rare but life-threatening illness that occurs in children without preexisting liver disease. The rarity of the disease, along with its severity and heterogeneity, presents unique clinical challenges to the physicians providing care for pediatric patients with acute liver failure. In this review, practical clinical approaches to the care of critically ill children with acute liver failure are discussed with an organ system-specific approach. The underlying pathophysiological processes, major areas of uncertainty, and approaches to the critical care management of pediatric acute liver failure are also reviewed.

Abstract
Liver transplantation (LT) is the only proven treatment for pediatric acute liver failure (PALF). However, over a period of time, spontaneous native liver survival is increasingly reported, making us wonder if we are overtransplanting children with acute liver failure (ALF). An effective prognostic model for PALF would help direct appropriate organ allocation. Only patients who would die would undergo LT, and those who would spontaneously recover would avoid unnecessary LT. Deriving and validating such a model for PALF, however, encompasses numerous challenges. In particular, the heterogeneity of age and etiology in PALF, as well as a lack of understanding of the natural history of the disease, contributed by the availability of LT has led to difficulties in prognostic model development. Several prognostic laboratory variables have been identified, and the incorporation of these variables into scoring systems has been attempted. A reliable targeted prognostic model for ALF in Wilson's disease has been established and externally validated. The roles of physiological, immunological, and metabolomic parameters in prognosis are being investigated. This review discusses the challenges with prognostic modeling in PALF and describes predictive methods that are currently available and in development for the future.
