RESUMO
Objective:To investigate the clinical characteristics and prognosis of children with acute pancreatitis(AP)admitted to the pediatric intensive care unit(PICU).Methods:The etiology, clinical data, imaging features, complications, and outcomes of children with AP admitted to PICU at Shanghai Children′s Hospital from July 2016 to June 2021 were retrospectively analyzed.Results:Totally, 47 patients with AP including 24 males and 23 females were enrolled.The mean age was 84(48, 144)months.Four patients with mild AP, 5 patients with moderately severe AP(MSAP)and 38 cases with severe AP(SAP)were diagnosed.The main etiology was drug-related pancreatitis in 23 cases(48.9%). The organ dysfunction mainly included shock in 28 cases(59.6%), acute respiratory failure in 21 cases(44.7%), gastrointestinal disorders in 30 cases(63.8%), and coagulopathy in 29 cases(61.7%). The complications included capillary leakage syndrome in 18 cases(38.3%)and hyperglycemia(>8 mmol/L)in 24 cases(51.1%). Serum amylase and lipase levels were increased in 47 cases(100%). There were significant differences in blood lactate[3.0(2.1, 4.5)mmol/L vs.1.6(1.1, 3.1)mmol/L, P=0.013], and the use of vasoactive drugs[15.0(0, 75.0)vs.0(0, 8.8), P=0.035] between drug-induced pancreatitis and non-drug-induced pancreatitis.All the patients′conditions were improved after treatment and transferred out of PICU. Conclusion:The etiology of acute pancreatitis in children is mainly drug-related, and the main organ dysfunction includes shock, acute respiratory failure, gastrointestinal dysfunction and coagulation dysfunction.The prognosis of childhood pancreatitis is good.
RESUMO
Objective:To summarize the clinical features, imaging changes, treatment, and prognosis of children with severe autoimmune encephalitis (AE).Methods:A retrospective study was conducted on patients with severe AE admitted to PICU of Shanghai Children’s Hospital from June 2017 to May 2020. Clinical features, treatment protocols and follow-up data were collected.Results:A total of 27 children were included, among which 18 cases (66.7%) were girls. The on-set age was (7.9±3.2) years. Eighteen cases were diagnosed with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis. Fever (77.8%), headache (40.7%) and vomiting (44.4%) were most of prodromal symptoms in children with severe AE. Patients’ neurological symptoms showed seizures (88.9%), mental behavior abnormalities (81.5%), speech disorders (70.4%) and dyskinesia (70.4%). Moreover, epileptic discharge and slow wave activity were critical feature of electroencephalogram (EEG) abnormalities, and the abnormal signal changes on T2-weighted and FLAIR sequence of head MRI were in the posterior horn of the lateral ventricle. In addition, the main comorbidities included refractory status epilepticus (RSE), cardiovascular dysfunction, central hypoventilation syndrome and acute intracranial hypertension syndrome. For patients with central respiratory failure, the median duration of mechanical ventilation was 19.8 (14.8, 29.1) days. According to treatment protocol, the first-line immune treatment included the combination therapies of methylprednisolone, intravenous immunoglobulin (IVIG) and therapeutic plasma exchange (TPE). Eighteen cases were given with methylprednisolone [10-30 mg/(kg. d), 3-5 d] + IVIG (2 g/kg, within 2 d) + TPE, 1 case was treated with methylprednisolone [10-30 mg/(kg·d), 3-5 d] + TPE and 8 cases were given with[10-30 mg/(kg·d), 3-5 d] + IVIG (2 g/kg, within 2 d). Sequential therapy was given with methylprednisolone (1-2 mg/kg), gradually reduced from 3 to 6 months. Finally, 16 children (59.3%) had neurological damages at the first discharge, among which 8 cases (29.6%) were with dyskinesia, 5 cases (18.5%) were with speech disturbance, and 5 cases (18.5%) were with abnormal mental behaviors.Conclusions:The most of first clinical symptom is epileptic seizures in pediatric severe AE, and most of these patients are diagnosed with Anti-NMDA receptor encephalitis. RSE, cardiovascular dysfunction, central respiratory and acute intracranial hypertension syndrome constitute to main organ dysfunctions.
RESUMO
Objective:To explore the clinical characteristics and prognostic risk factors of accidental injuries in pediatric intensive care unit(PICU).Methods:The children with accidental injuries admitted to the PICU at Shanghai Children′s Hospital from January 2017 to December 2019 were analyzed retrospectively.The patients were divided into survival group and death group according to outcome.We collected the patients′ clinical data and laboratory indexes, and analyzed the differences between two groups.Multivariate Logistic regression was used to screen the risk factors of death and receiver-operating characteristic(ROC)curve was used to determine the threshold.Results:(1)A total of 253 children were included, accounting for 5.2% of PICU hospitalization during the same period.There were 137 males(54.2%)and 116 females(45.8%), with an average age of 45(19, 96)months.The top three causes of accidental injuries were fall injury in 82 cases(32.4%), traffic accident in 70 cases(27.7%)and foreign body in 39 cases(15.4%). There were 22 cases of deaths, with a fatality rate of 8.7%.(2)The mean arterial pressure at admission in the death group was lower than that in the survival group( P<0.05), and the total length of stay was longer( P<0.001). There were significant differences in Glasgow coma scale, Pediatric Risk of Mortality Scoring Ⅲ(PRISM Ⅲ)between the two groups( P<0.001). In the death group, and the blood lactic acid(LA) significantly increased( P<0.001), hemoglobin and fibrinogen were lower than those in the survival group, the activated partial thromboplastin time and prothrombin time(PT)were significantly prolonged( P<0.001). (3)Multivariate Logistic regression analysis showed that PRISM Ⅲ score, LA and PT were independent risk factors for the death of accidental injuries.The area under curve(AUC)of PRISM Ⅲ score was 0.987(95% CI 0.976-0.999, P<0.001)and the cut-off value was 11 with a sensitivity of 100% and a specificity of 95.7%.The AUC of LA was 0.886(95% CI 0.810-0.961, P<0.001)and the cut-off value was 3.1 mmol/L with a sensitivity of 85.7% and a specificity of 77.3%.The AUC of PT was 0.835(95% CI 0.730-0.941, P<0.001)and the cut-off value was 13.9 s with a sensitivity of 86.6% and a specificity of 72.7%. Conclusion:The main accidental injuries in PICU of our hospital in the past three years are falling injuries, traffic accidents and foreign body injuries.PRISM Ⅲ score, LA and PT at admission are independent risk factors for predicting death.
RESUMO
Objective To investigate the association and predictive value of aspartate transaminase to platelet ratio index(APRI) in sepsis-associated liver injury(SALI). Methods We retrospectively ana-lyzed the medical records of patients with sepsis admitted to PICU in Shanghai Children′s Hospital of Shanghai Jiaotong University from April 2015 to March 2017. According to whether liver injury occurred in the sepsis patients during hospitalization,all the patients were divided into SALI group (n=34) and sepsis group(n=222). The clinical characteristics,serological indexes within 24 hours in the PICU,and the ratio of aspartate transaminase to alanine transaminase( AAR) and APRI were collected and analyzed. The receiver operating characteristic( ROC) curve was used to evaluate the power of APRI for the prediction of SALI. Results (1)A total of 256 patients were enrolled in this study. There were 34 cases with SALI,and there were 222 patients with sepsis only,the incidence of SALI was 13. 3％. (2) The values of APRI and AAR were both higher in the SALI group compared with the sepsis group[APRI:7. 12(1. 71,26. 96) vs. 0. 38 (0. 21,0. 83),P<0. 001;AAR:1. 43(0. 94,2. 69) vs. 2. 17(1. 35,2. 96),P<0. 05]. (3)The multivariate Logistic regression analysis showed that total bilirubin, APRI, AAR and platelet were the independent risk factors of SALI(P<0. 05). (4)In addition,the area under the ROC curve(AUC)for the APRI was 0. 891 (95％CI 0. 815-0. 966,P<0. 001),cut-off value was 1. 73,which was superior to total bilirubin(AUC =0. 744,95％CI 0. 634-0. 853,P<0. 001) and platelet(AUC=0. 726,95％CI 0. 611-0. 841,P<0. 001). The clinical sensitivity and specificity of the APRI for identification of SALI from sepsis was 80. 0％ and 92. 2％, respectively. Conclusion APRI is an independently risk factor for the occurrence of SALI and is a precursory marker for SALI.
RESUMO
Chimeric antigen receptor T lymphocyte immunological therapy (CAR-T)is a new oncologic immunotherapy in recent years,which has been widely used in patients with leukemia and lymphoma and achieved a certain effect.Neuroblastoma is one of the most common extracranial solid tumors in children and over 50％ of patients have metastatic recurrence when first diagnosed.The prognosis for the high-risk neuroblastoma remains poor at the moment and it's time to look for new treatments.In this review,we summarize the basic structure and development of CAR-T,discuss the principles and risks of CAR-T in the treatment of neuroblastoma,and give an outlook to CAR-T in the treatment of solid tumors.
