RESUMO
INTRODUCTION: This study aimed to evaluate prognostic factors and outcomes in a single-center PICU cohort that received continuous renal replacement therapy (CRRT). METHODS: This retrospective study analyzed clinical characteristics, laboratory data, and outcomes. Ninety-day mortality and advanced chronic kidney disease (CKD) (eGFR <60 mL/min/1.73 m2) were defined as primary and secondary outcomes, respectively. RESULTS: Seventy-five patients were enrolled, all of whom received CRRT for indications including acute kidney injury with complicated refractory metabolic acidosis, electrolyte derangement, and existed or impending fluid overload. The 90-day mortality and advanced CKD were 53% and 29%, respectively. Multivariate Cox regression analysis demonstrated that only underlying bone marrow transplantation (BMT) (HR 4.58; 95% CI: 2.04-10.27) and a high pSOFA score (HR 1.12; 95% CI: 1.01-1.23) were independent risk factors for 90-day mortality. Among survivors, ten developed advanced CKD on the 90th day, and this group had a higher serum fibrinogen level (OR 1.01; 95% CI: 1.01-1.03) at the start of CRRT. CONCLUSION: In critically ill children with AKI requiring CRRT, post-BMT and high pSOFA scores are independent risk factors for 90-day mortality. Additionally, a high serum fibrinogen level at the initiation of CRRT is associated with the development of advanced CKD.

BACKGROUND: SARS-CoV-2 posed a threat to children during the early phase of Omicron wave because many patients presented with febrile seizures. The study aimed to investigate predicting factors for acute encephalopathy of children infected by SARS-CoV-2 Omicron variant presenting with febrile seizures. METHODS: The retrospective study analyzed data from pediatric patients who visited the emergency department of Chang Gung Memorial Hospital in Taiwan between April and July 2022. We specifically focused on children with COVID-19 who presented with febrile seizures, collecting demographic, clinical, and laboratory data at the pediatric emergency department, as well as final discharge diagnoses. Subsequently, we conducted a comparative analysis of the clinical and laboratory characteristics between patients diagnosed with acute encephalopathy and those with other causes of febrile seizures. RESULTS: Overall, 10,878 children were included, of which 260 patients presented with febrile seizures. Among them, 116 individuals tested positive for SARS-CoV-2 and of them, 14 subsequently developed acute encephalopathy (12%). Those with acute encephalopathy displayed distinctive features, including older age (5.1 vs. 2.6 years old), longer fever duration preceding the first seizure (1.6 vs. 0.9 days), cluster seizure (50% vs. 16.7%), status epilepticus (50% vs. 13.7%) and occurrences of bradycardia (26.8% vs. 0%) and hypotension (14.3% vs. 0%) in the encephalopathy group. Besides, the laboratory findings in the encephalopathy group are characterized by hyperglycemia (mean (95% CI) 146 mg/dL (95% CI 109-157) vs. 108 mg/dL (95% CI 103-114) and metabolic acidosis (mean (95% CI) pH 7.29(95% CI 7.22-7.36) vs. 7.39 (95%CI 7.37-7.41)). CONCLUSIONS: In pediatric patients with COVID-19-related febrile seizures, the occurrence of seizures beyond the first day of fever, bradycardia, clustered seizures, status epilepticus, hyperglycemia, and metabolic acidosis should raise concerns about acute encephalitis/encephalopathy. However, the highest body temperature and the severity of leukocytosis or C-reactive protein levels were not associated with poor outcomes.

OBJECTIVE: Given the scarcity of studies analyzing the clinical predictors of pediatric septic cases that would progress to septic shock, this study aimed to determine strong predictors for pediatric emergency department (PED) patients with sepsis at risk for septic shock and mortality. METHODS: We conducted chart reviews of patients with ≥ 2 age-adjusted quick Sequential Organ Failure Assessment score (qSOFA) criteria to recognize patients with an infectious disease in two tertiary PEDs between January 1, 2021, and April 30, 2022. The age range of included patients was 1 month to 18 years. The primary outcome was development of septic shock within 48 h of PED attendance. The secondary outcome was sepsis-related 28-day mortality. Initial important variables in the PED and hemodynamics with the highest and lowest values during the first 24 h of admission were also analyzed. RESULTS: Overall, 417 patients were admitted because of sepsis and met the eligibility criteria for the study. Forty-nine cases progressed to septic shock within 48 h after admission and 368 were discharged without progression. General demographics, laboratory data, and hemodynamics were analyzed by multivariate analysis. Only the minimum diastolic blood pressure/systolic blood pressure ratio (D/S ratio) during the first 24 h after admission remained as an independent predictor of progression to septic shock and 28-day mortality. The best cutoff values of the D/S ratio for predicting septic shock and 28-day mortality were 0.52 and 0.47, respectively. CONCLUSIONS: The D/S ratio is a practical bedside scoring system in the PED and had good discriminative ability in predicting the progression of septic shock and in-hospital mortality in PED patients. Further validation is essential in other settings.

We present a pediatric case of acute hemorrhagic leukoencephalitis associated with SARS-CoV-2 Omicron BA 2.0 infection. A previously healthy girl presented with ataxia and diplopia three weeks after the COVID-19 confirmation from a nasopharyngeal swab. Acute and symmetrical motor weakness and drowsiness ensued within the following 3 days. She then became spastic tetraplegic. MRI revealed multifocal lesions in the cerebral white matter, basal ganglia, and brainstem, with hemorrhagic changes confirmed with T1-hyperintensity and hypointensity on susceptibility-weighted images. Peripheral areas of decreased diffusion, increased blood flow, and rim contrast enhancement were noted in the majority of lesions. She was treated with a combination of intravenous immunoglobulin and methylprednisolone pulse therapy. Neurological deterioration ensued with coma, ataxic respiratory pattern and decerebrate posture. Repeated MRI performed on day 31 revealed progression of abnormalities, hemorrhages and brain herniation. Despite the administration of plasma exchange, she died two months after admission.

BACKGROUND: Croup caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an emerging disease, and data on the risk factors associated with disease severity are still limited. The Westley croup score (WS) is widely used to assess croup severity. The current study aimed to analyze biomarkers associated with the WS and clinical outcomes in patients with croup and coronavirus disease 2019 in the pediatric emergency department (PED). POPULATION AND METHOD: Patients diagnosed with croup caused by SARS-CoV-2 were admitted at two PEDs. Clinical data including age, WS, length of hospital stay, initial laboratory data, and treatment were analyzed. Clinical parameters were evaluated via multivariate logistic regression analysis. The best cutoff values for predicting croup severity and outcomes were identified using the receiver operating characteristic curve. RESULT: In total, 250 patients were assessed. Moreover, 128 (51.2%) patients were discharged from the PED, and 122 (48.8%) were admitted to the hospital. Mild, moderate, and severe croup accounted for 63.6% (n = 159), 32% (n = 80), and 4.4% (n = 11) of all cases, respectively. A high mean age (years), neutrophil count (%), neutrophil-to-lymphocyte ratio (NLR), ALT (U/L), procalcitonin (ng/mL), and hemoglobin (g/dL) level, and length of hospital stay (days), and a low lymphocyte count (%) and blood pH were associated with croup severity and need for intensive care. Based on the multivariate logistic regression model, the NLR remained independent factors associated with croup severity and prognosis. Further, NLR was significantly correlated with WS. The area under the receiver operating characteristic curve of NLR for predicting a WS of ≥3 was 0.895 (0.842-0.948, p < 0.001), and that for predicting ICU admission was 0.795 (0.711-0.879, p < 0.001). The best cutoff values for a WS of ≥3 and ICU admission were 1.65 and 2.06, respectively. CONCLUSION: NLR is correlated with WS and is a reliable, easy-to-use, and cheap biomarker for the early screening and prognosis of croup severity in the PED. A higher NLR may indicate severe croup and the need for further treatment. And the WS score remains reliable for estimating the severity of croup caused by SARS-CoV-2 and the risk of intensive care.

PURPOSE: Enterovirus A71 (EV71) causes a broad spectrum of childhood diseases, ranging from asymptomatic infection or self-limited hand-foot-and-mouth disease (HFMD) to life-threatening encephalitis. The molecular mechanisms underlying these different clinical presentations remain unknown. We hypothesized that EV71 encephalitis in children might reflect an intrinsic host single-gene defect of antiviral immunity. We searched for mutations in the toll-like receptor 3 (TLR3) gene. Such mutations have already been identified in children with herpes simplex virus encephalitis (HSE). METHODS: We sequenced TLR3 and assessed the impact of the mutations identified. We tested dermal fibroblasts from a patient with EV71 encephalitis and a TLR3 mutation and other patients with known genetic defects of TLR3 or related genes, assessing the response of these cells to TLR3 agonist poly(I:C) stimulation and EV71 infection. RESULTS: Three children with EV71 encephalitis were heterozygous for rare mutations-TLR3 W769X, E211K, and R867Q-all of which were shown to affect TLR3 function. Furthermore, fibroblasts from the patient heterozygous for the W769X mutation displayed an impaired, but not abolished, response to poly(I:C). We found that TLR3-deficient and TLR3-heterozygous W769X fibroblasts were highly susceptible to EV71 infection. CONCLUSIONS: Autosomal dominant TLR3 deficiency may underlie severe EV71 infection with encephalitis. Human TLR3 immunity is essential to protect the central nervous system against HSV-1 and EV71. Children with severe EV71 infections, such as encephalitis in particular, should be tested for inborn errors of TLR3 immunity.

BACKGROUND: Vasoplegia is vascular hyporesponsiveness to vasopressors and is an important phenomenon in children with refractory septic shock. This study aimed to develop an objective formula correlated with vasoplegia and evaluate the predictive power for mortality in children with refractory septic shock. MATERIALS AND METHODS: We retrospectively analyzed children with refractory septic shock admitted to a pediatric intensive care unit (PICU) and monitored their hemodynamics via a pulse index continuous cardiac output (PiCCO) system. Serial hemodynamic data including cardiac index (CI), systemic vascular resistant index (SVRI) and vasoactive-inotropic score (VIS) were recorded during the first 72 hours after PICU admission. We defined vascular reactivity index (VRI) as SVRI/VIS and analyzed the effect of VRI in predicting mortality in children with refractory septic shock. RESULTS: Thirty-three children with refractory septic shock were enrolled. The SVRI was lower in the mortality group compared to the survival group (P < .05). The average area under the receiver operating characteristic curve of VRI within the first 72 hours was 0.8 and the serial values of VRI were significantly lower in the mortality group during the period from 0 to 48 hours (P < .05). However, there were no significant differences in serial CI values between the survival and mortality groups. CONCLUSIONS: Vasoactive-inotropic score may potentially be used to quantify the severity of vasoplegia based on the clinical response of vessels after resuscitation with vasopressors. Lower VRI levels may indicate a higher risk of mortality in children with septic shock.

Enterovirus A71 (EV-A71) is one of the causative pathogens of hand, foot, and mouth disease (HFMD), which may cause severe neurological and cardiopulmonary complications in children. In this review, we discuss the pathogenesis, clinical manifestations, management strategy, and clinical outcomes of cardiopulmonary failure (CPF) in patients with EV-A71 infection.The pathogenesis of CPF involves both catecholamine-related cardiotoxicity following brainstem encephalitis and vasodilatory shock due to cytokine storm. Sympathetic hyperactivity, including tachycardia and hypertension, are the early clinical manifestations of cardiopulmonary involvement, which may progress to pulmonary edema/hemorrhage and/or CPF. The management strategy comprises multidisciplinary supportive treatment, including fluid management, positive pressure ventilation support, and use of milrinone, vasopressors, and inotropes. Some patients may require extracorporeal membrane oxygenation. Major neurological sequelae are almost inevitable once a child develops life-threatening illness. Long-term care of these children is an important medico-social issue.

BACKGROUND: Percutaneous ultrasound-guided renal biopsy (PURB) is an invasive but essential procedure in establishing the histologic diagnosis of pediatric renal diseases. Large studies which describe PURB complications and its contributory risk factors are scarce in the pediatric literature. METHODS: Patients who underwent real-time PURB from September 2011 to August 2017 were retrospectively reviewed. Data pertaining to clinical characteristics, histologic diagnosis and biopsy-related complications were collected. In addition, the risk factors for complications were also analyzed. RESULTS: Overall, 183 patients (109 females) were enrolled and 201 biopsies were obtained. The mean age was 14.4 ± 13.7 years. Over 98% of the biopsies were considered adequate in quality. The major complications were perirenal hematoma requiring blood transfusion (4 cases, 2.0%), followed by perirenal abscess (1 case, 0.5%) and arteriovenous fistula (1 case, 0.5%). All patients recovered without sequelae after treatment. Hypertension, low estimated glomerular filtration rate (eGFR) and anemia were more common in patients with complication than in those without. Further logistic regression model analysis demonstrated that eGFR <30 ml/1.73m2/min was an independent risk factor for major complications. CONCLUSIONS: Perirenal hematoma needing blood transfusion is the most common major complication for children undergoing renal biopsy. Low eGFR is an independent risk factor for major complications. Early recognition and timely treatment should be delivered to children with renal function impairment accordingly.

PURPOSE: The role of methylprednisolone pulse therapy as adjuvant treatment of Streptococcus pneumoniae meningitis complicated by cerebral infarction has rarely been reported. METHODS: We reported a case report and also performed a systematic literature review. RESULTS: A 1-year 2-month-old boy who presented with high fever, status epilepticus, and septic shock was diagnosed with cerebral infarction caused by Streptococcus pneumoniae meningitis on magnetic resonance imaging (MRI). He was treated with methylprednisolone pulse therapy and his clinical condition gradually improved thereafter. At the follow-up visit 1 year after discharge, he was able to sit without support, but he had moderate delays in speech and developmental milestones and epilepsy sequelae. CONCLUSION: In severe cases, the use of high-dose methylprednisolone should be considered to modulate the inflammatory response in patients with severe cerebral infarction caused by Streptococcus pneumoniae meningitis.

During recent 20 years, enterovirus A71 (EV-A71) has emerged as a major concern among pediatric infectious diseases, particularly in the Asia-Pacific region. The clinical manifestations of EV-A71 include uncomplicated hand, foot, and mouth disease, herpanina or febrile illness and central nervous system (CNS) involvement such as aseptic meningitis, myoclonic jerk, polio-like syndrome, encephalitis, encephalomyelitis and cardiopulmonary failure due to severe rhombencephalitis. In follow-up studies of patients with EV-A 71 CNS infection, some still have hypoventilation and need tracheostomy with ventilator support, some have dysphagia and need nasogastric tube or gastrostomy feeding, some have limb weakness/astrophy, cerebellar dysfunction, neurodevelopmental delay, lower cognition, or attention deficiency hyperactivity disorder. Long term sequelae may be related to greater severity of CNS involvement or neuron damage, hypoxia and younger age of onset.

BACKGROUND: Pneumatosis intestinalis and portomesenteric venous gas are usually caused by necrotizing enterocolitis; however they can occur secondary to abusive abdominal trauma with bone fractures and bruising. It is difficult to recognize initially if there is no bruising on the skin or bone fractures. CASE PRESENTATION: We report a 1-year-old child with no obvious history of trauma who presented with conscious disturbance. Abdominal computed tomography showed acute ischemic bowel complicated with pneumatosis intestinalis and portomesenteric venous gas. The first impression was septic shock with acute ischemic bowel. Two weeks after admission, brain magnetic resonance imaging showed subdural hemorrhage of different stages over bilateral fronto-parietal convexities and diffuse axonal injury, suggesting abusive head trauma. He was subsequently diagnosed with occult child abuse. CONCLUSION: Pneumatosis intestinalis and portomesenteric venous gas are rare except in cases of prematurity. Occult abusive abdominal trauma should be considered as a differential diagnosis in patients with pneumatosis intestinalis and portomesenteric venous gas, even without any trauma on the skin or bone fractures.

PURPOSE: To report the clinical characteristics of abusive head trauma (AHT) in Taiwan and identify the risk factors associated with mortality of these patients. METHODS: Children with clinically diagnosed AHT from January 1, 2000, to October 31, 2015 were reviewed. The demographic data, clinical features, and associated retinal and radiologic findings were analyzed. The multivariable logistic regression model analysis was performed to identify the risk factors associated with in-hospital mortality. RESULTS: A total of 75 children were included. The mean age was 7.31 ± 6.57 months (range, 1-36 months). Retinal hemorrhages were detected in 69 children with AHT (92%). The majority of retinal hemorrhages were characterized by hemorrhagic numbers higher than ten (74.7%), multi-layered (54.7%), and extension beyond the posterior pole to the peripheral retina (73.3%). Twenty children (26.7%) had macular retinoschisis. As a direct result of AHT, ten children died in the hospital (13.3%). Logistic regression showed that respiratory distress or apnea (adjusted odds ratio [OR] = 22.46; 95% confidence interval [CI], 2.24-225.33; P = .0082), vomiting (adjusted OR = 11.94; 95% CI, 1.31-108.403; P = .0276), retinal finding of macular retinoschisis (adjusted OR = 8.9; 95% CI, 1.01-78.65; P = .0493), and the presence of subarachnoid hemorrhage (SAH) (adjusted OR = 15.17; 95% CI, 1.40-64.84; P = .0255) were independently associated with mortality. CONCLUSIONS: Respiratory distress or apnea, vomiting, SAH, and macular retinoschisis are independently associated with mortality in abusive head trauma. A complete ophthalmologic examination with the immediate visualization of intraocular injury should be performed to clarify the likelihood of child abuse and predict a potential poor neurologic outcome.

BACKGROUND: Invasive pneumococcal disease (IPD) results in high morbidity and mortality globally each year, although it is a vaccine-preventable disease. This study aimed to characterize the clinical features of IPD in a pediatric intensive care unit (PICU) in Taiwan. The seven-valent pneumococcal conjugate vaccine (PCV7) was introduced in the private sector in October 2005. The estimated coverage rate of PCV7 vaccination in 2010 was 45.5% among children <5 years of age. METHODS: We conducted a retrospective study at a single center in northern Taiwan for invasive pneumococcal disease in a PICU from 2009 to 2013. Demographic characteristics, clinical courses, serotype, antibiotic susceptibility, and outcomes were analyzed. RESULTS: Over the 5-year study period, 2167 patients were admitted to the PICU; 48 (2.2%) had IPD. There were 29 female and 19 male patients. Their mean age was 3.7 years (range 0.7-12.5 years, with the peak age at 2-5 years; n = 30, 63%). Pneumonia was the most frequent type (n = 38, 79%), followed by meningitis (n = 10, 21%). In total, three patients died, all within 72 h after admission; the final diagnoses were all meningitis. Thirty-four children with pneumonia received chest tube insertion for pleural effusion drainage. Of them, 22 (65%) finally still underwent video-assisted thoracoscopic surgery. Eight (17%) children had hemolytic uremic syndrome, and seven of them underwent hemodialysis. In total, 37 serotypes were detected; 95% were covered by PCV13. Serotype 19A was most common (54%) overall; however, in those with meningitis, serotype 19 F was most common. CONCLUSIONS: Meningitis is the most severe type of invasive pneumococcal disease in our pediatric intensive care unit. It may progress rapidly even when subjects are given antibiotics promptly. The most common serotype in meningitis is 19 F, which is vaccine preventable. Thus, universal mass pneumococcal vaccination is still needed.

BACKGROUND: Enterovirus 71 (EV71) is a great disease burden across the whole world, particularly in Southeast Asia. However, in recent decades, the pathogenesis of severe EV71 infection was not well understood. This study was aimed to investigate the correlation between the presence of viremia and the clinical severity of EV71 infection. METHODS: We organized a prospective cohort study and enrolled laboratory-confirmed EV71 cases in six tertiary care hospitals in Taiwan during the EV71 epidemic from 2011 to 2012. Blood samples were collected once in the acute stage, on the first day of admission. We used real-time RT-PCR to detect EV71 viremia. Demographical and clinical data were collected and the clinical severity was categorized into four grades. Data analysis was performed to identify the risk factors of viremia and the correlation between viremia and clinical severity of EV71 infection. RESULTS: Of the total 224 enrolled patients, 59 (26%) patients were confirmed to have viremia. Two-thirds (68%) of viremic cases were detected within the first three days of infection. Viremia occurred more frequently in children under the age of one year old (odds ratios [OR] 4.82, p < 0.001) but the association between the presence of viremia and complicated EV71 infection was not found (OR 1.02, p = 0.96). In the viremia group, patients had significantly more severe complications if viremia was detected after the third day of disease onset (26% vs. 5%, p = 0.03). CONCLUSIONS: Viremia occurred more frequently in children under the age of one year and viremia detected beyond three days after the onset of disease correlated with more severe disease in EV71 patients.

BACKGROUND: Kabuki syndrome is a multi-system disorder with peculiar facial features, and ophthalmic abnormalities are frequently involved. This case report of a child with Kabuki syndrome describes two new previously unreported ophthalmic conditions. CASE PRESENTATION: A 3-year-old Taiwanese boy with Kabuki syndrome had a short stature, spinal dysraphism, intellectual disability and typical facial features. Ophthalmic findings which have been previously reported in the literature and in this patient, included ptosis, esotropia, coloboma of the iris, retina, choroid and optic disc, and microcornea. The newly identified ophthalmic features in this patient included colobomatous microphthalmos and a dysplastic and elevated disc without central cupping. The genetic analysis identified an MLL2 gene mutation. CONCLUSION: The presentations of a dysplastic disc and colobomatous microphthalmia are rarely reported in patients with Kabuki syndrome, but these ophthalmic abnormalities may affect vision. Detailed ophthalmic evaluations in children with Kabuki syndrome are advised.

Enterovirus A71 (EV-A71) infections pose a significant public health concern in the Asia-Pacific region. EV-A71 is primarily responsible for causing hand, foot, and mouth disease (HFMD) in children. However, this virus can also lead to severe and potentially fatal neurological consequences in affected individuals. This review aims to provide a comprehensive understanding of the molecular virology, epidemiology, and recombination events associated with EV-A71. The literature extensively covers the clinical manifestations and neurological symptoms that accompany EV-A71 infections. One of the complications explored in this review is brainstem encephalitis, which can arise as a result of EV-A71 infections. Brainstem encephalitis refers to inflammation of the brainstem, a critical region responsible for various bodily functions. The review examines the underlying mechanisms, diagnostic criteria, treatment options, and prognosis for central nervous system infections involving EV-A71. Neurological complications associated with EV-A71 infections are diverse and can have severe consequences. These complications may include aseptic meningitis, acute flaccid paralysis, and acute transverse myelitis. The review delves into the pathophysiology of these complications, shedding light on the molecular mechanisms through which EV-A71 affects the central nervous system. Accurate diagnosis of EV-A71 infections is crucial for appropriate management and treatment. Treatment options for EV-A71 infections primarily focus on supportive care, as there are currently no specific antiviral drugs available for this virus. The review highlights the importance of managing symptoms, such as fever, dehydration, and pain relief, to alleviate the burden on affected individuals. Prognosis for individuals with central nervous system (CNS) infections involving EV-A71 can vary depending on the severity of the complications. The review provides insights into the long-term outcomes and potential neurological sequelae associated with EV-A71 infections. In conclusion, EV-A71 infections have emerged as a major public health concern in the Asia-Pacific region. This review aims to enhance our understanding of the molecular virology, epidemiology, and neurological complications associated with EV-A71. By examining the underlying mechanisms, diagnostic criteria, treatment options, and prognosis, this review contributes to the development of effective strategies for the prevention, diagnosis, and management of EV-A71 infections. The paper presents a comprehensive analysis of worldwide data pertaining to outbreaks of EV-A71 and HFMD. The subsequent discourse delves into the advancement and strategic formulation pertaining to the creation of vaccines targeting EV-A71. In summary, this study provides a comprehensive examination of the potential obstacles and considerations involved in the management and treatment of EV-A71 infections. Additionally, it proposes suggestions for future research and development endeavors with the objective of formulating efficacious treatment approaches for this viral infection.
RESUMO
Children have been reported to be less affected and to have milder severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection than adults during the coronavirus disease 2019 (COVID-19) pandemic. However, children, and particularly those with underlying disorders, are still likely to develop critical illnesses. In the case of SARS-CoV-2 infection, most previous studies have focused on adult patients. To aid in the knowledge of in-hospital care of children with COVID-19, this study presents an expert review of the literature, including the management of respiratory distress or failure, extracorporeal membrane oxygenation (ECMO), multisystem inflammatory syndrome in children (MIS-C), hemodynamic and other organ support, pharmaceutical therapies (anti-viral drugs, anti-inflammatory or antithrombotic therapies) and management of cardiopulmonary arrest.

BACKGROUND: Acute necrotizing encephalopathy (ANE) is a fulminant disease with poor prognosis. Cytokine storm is the important phenomenon of ANE that affects the brain and multiple organs. The study aimed to identify whether hyperferritinemia was associated with poor prognosis in patients with ANE. METHODS: All patients with ANE had multiple symmetric lesions located in the bilateral thalami and other regions such as brainstem tegmentum, cerebral white matter, and cerebellum. Neurological outcome at discharge was evaluated by pediatric neurologists using the Pediatric Cerebral Performance Category Scale. All risk factors associated with poor prognosis were further analyzed using receiver operating characteristic curve analysis. RESULTS: Twenty-nine patients with ANE were enrolled in the current study. Nine (31%) patients achieved a favorable neurological outcome, and 20 (69%) patients had poor neurological outcomes. results The group of poor neurological outcome had significantly higher proportion of shock on admission and brainstem involvement. Based on multivariate logistic regression analysis, ferritin, aspartate aminotransferase (AST), and ANE severity score (ANE-SS) were the predictors associated with outcomes. The appropriate cutoff value for predicting neurological outcomes in patients with ANE was 1823 ng/mL for ferritin, 78 U/L for AST, and 4.5 for ANE-SS. Besides, comparison analyses showed that higher level of ferritin and ANE-SS were significantly correlated with brainstem involvement (P < 0.05). CONCLUSIONS: Ferritin may potentially be a prognostic factor in patients with ANE. Hyperferritinemia is associated with poor neurological outcomes in patients with ANE and ferritin levels more than 1823 ng/mL have about eightfold increased risk of poor neurological outcome.
