RESUMEN
Hyper-IgE syndrome (HIES) comprises a group of rare primary immunodeficiencies, which are characterized by extremely high serum IgE levels, eczema, recurrent skin and pulmonary infections.Signal transduction and activator of transcription 3( STAT3)-HIES is the most common type, which is caused by dominant-negative mutations in STAT3.STAT3-HIES confers broad innate and acquired immune defects, defects in skeletal, connective tissue, and vascular functions, causing a clinical phenotype including eczema, staphylococcal and fungal skin and pulmonary infections, scoliosis and minimal trauma fractures, vascular tortuosity and aneurysm.In this article, the advance in diverse clinical manifestations and management strategies of STAT3-HIES was summarized.
RESUMEN
Objective:To analyze the clinical characteristics of pulmonary vein stenosis (PVS) in children, and to explore its treatment and prognostic factors.Methods:The clinical data of 19 children with PVS treated in Beijing Children′s Hospital, Capital Medical University from October 2016 to March 2022 were analyzed retrospectively.There were 16 males and 3 females.The median age at diagnosis was (2.81±1.95) years.A descriptive analysis of clinical characteristics of children was made.Results:Of the 19 children, 14 cases (73.7%) had primary PVS and 5 cases (26.3%) had secondary PVS after surgery of anomalous pulmonary venous connection (APVC). Thirteen children (68.4%) had hemoptysis.In the hemoptysis children, 5 cases had life-threatening massive hemoptysis, and 11 cases (57.9%) had a history of recurrent respiratory tract infection or pneumonia.Other manifestations of hemoptysis included failure to thrive (6 cases), cyanosis (5 cases), and dyspnea (3 cases). Complications were pulmonary hypertension (6 cases) and right heart failure (3 cases). There were 16 cases (84.2%) of unilateral PVS and 3 cases of bilateral PVS.Interlobular septal thickening, grid shadow and ground glass opacities were found on CT of all PVS cases.Ten cases underwent surgery, and 2 cases of them received angioplasty, but restenosis occurred in both of them.Eight children underwent pulmonary lobectomy, and their clinical symptoms were all relieved after operation.Nine patients were treated conservatively, and 3 cases of them died of bilateral PVS secondary to APVC.The remaining 6 alive cases still had intermittent clinical symptoms during follow-up.Conclusions:Hemoptysis and recurrent respiratory tract infection are the main clinical manifestations of PVS in children, and life-threatening massive hemoptysis can occur.Lobectomy is an effective treatment for unilateral PVS.The prognosis of secondary PVS after APVC is poorer and its mortality is higher, compared with primary PVS.

RESUMEN
Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.
RESUMEN
China has classified the Corona Virus Disease 2019(COVID-19) as a statutory category B infectious disease and managed it according to Category B since January 8, 2023.In view that Omicron variant is currently the main epidemic strain in China, in order to guide the treatment of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infection in children with the times, refer to the Diagnosis and Treatment Protocol for Novel Coronavirus Infection (Trial 10 th Edition), Expert Consensus on Diagnosis, Treatment and Prevention of Novel Coronavirus Infection in Children (Fourth Edition) and the Diagnosis and Treatment Strategy for Pediatric Related Viral Infections.The Expert Consensus on the Diagnosis, Treatment and Prevention of Novel Coronavirus Infection in Children (Fifth Edition) has been formulated and updated accordingly on related etiology, epidemiology, pathogenic mechanism, clinical manifestations, auxiliary examination, diagnosis and treatment, and added key points for the treatment of COVID-19 related encephalopathy, fulminating myocarditis and other serious complications for clinical reference.
RESUMEN
Recently, there have been outbreaks of Group A Streptococcus (GAS) infection in foreign countries.The reasons are varied.With the relaxation of control for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infection, it is very likely that concurrent or secondary GAS infection peaks will occur at the same time as the number of Corona Virus Disease 2019(COVID-19) cases increases dramatically.Children are generally susceptible to GAS and are more vulnerable.In response to possible outbreaks, early identification of GAS infections and rational use of antibiotics are particularly important.
RESUMEN
Acute necrotizing encephalopathy (ANE) is a subtype of acute encephalopathy presented with disturbance of consciousness and symmetric bilateral thalamic necrosis in neuroradiology.Patients with ANE had a high mortality or severe neurological sequela.ANE usually secondary to virus infectious disease, in which influenza is a common etiology.During the 3 years of the worldwide pandemic of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection, ANE has become a severe complication and cause of death in children, which has aroused much concern.Here is a review of the research progress of epidemiology, pathogenesis, diagnosis, treatments and prognosis of ANE, in order to improve the knowledge of clinicians on this disease.
RESUMEN
Non-pharmaceutical interventions (NPIs) implemented during the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) epidemic have been proven to be effective in blocking the spread of the epidemic.While reducing SARS-CoV-2 transmission, NPIs also reduce children exposure to other pathogens, leading to a decline in the incidence of many viral and bacterial infections.The reduction in contact with viruses and bacteria and the delay or interruption of routine immunization during SARS-CoV-2 epidemic have resulted in insufficient immune stimulation of pathogens on the population, leading to an increase in susceptible populations and a decline in herd immunity, forming the immune debt during SARS-CoV-2 epidemic.After reducing or lifting NPIs, the incidence of some viral or bacterial infectious diseases was significantly higher than pre-epidemic.In this review, the definition, source, impact and strategies of immune debt during epidemic period were expounded, inorder to improve clinicians′ attention and understanding of immune debt and optimize the prevention of children′s infectious diseases.
RESUMEN
Asthma is a common chronic respiratory disease in children.Adolescent asthma is characterized by high prevalence rate, high mortality and poor disease control.The optimal adolescent asthma management is crucial to improve asthma control, as well as reduce the burden of asthma including mortality.The key of the management in adolescents with asthma is the self-management, which involves individual, family and social aspects.The imbalance between physical development and psychological development in adolescents leads to many challenges in the self-management in adolescents with asthma.This review elaborates the current situation, influence factors and promotional strategies of self-management in adolescents with asthma so as to achieve the optimal asthma self-management.
RESUMEN
The prevalence of anaphylaxis, which is underdiagnosed and undertreated, has been increasing recently.It was reported that about one fourth of anaphylaxis patients were children and there were some critical gaps in the initial treatment of anaphylaxis, including epinephrine use, when compared to the guidelines.Since most of anaphylaxis cases happen outside of medical institutions, and could recur unexpectedly, it is important for children with anaphylaxis to get long-term management.In order to improve management of anaphylaxis, a written China Children′s Anaphylaxis Emergency Action Plan (CCAEAP) is developed.It is a tool for children and parents/caregiver to recognize the symptoms and signs of anaphylaxis as early as possible and take proper action immediately, including using a predefined dose of intramuscular epinephrine and accessing to emergency department.
RESUMEN
Antipyretic-analgesics are currently one of the most prescribed drugs in children.The clinical application of antipyretic-analgesics for children in our country still have irrational phenomenon, which affects the therapeutic effect and even poses hidden dangers to the safety of children.In this paper, suggestions were put forward from the indications, dosage form/route, dosage suitability, pathophysiological characteristics of children with individual differences and drug interactions in the symptomatic treatment of febrile children, so as to provide reference for the general pharmacists when conducting prescription review.
RESUMEN
The diagnosis of food allergy in children is one hotspot attracting people′s attention in recent years.The incidence of it shows an increasing trend which exposes problems in the understanding of children′s food allergy in China, especially in the misdiagnosis and missed diagnosis.To further standardize the diagnosis and treatment of food allergy in children, based on the current domestic, foreign guidelines and relevant research evidence, the guideline recommends 16 clinical hot-button issues in the 4 aspects of diagnosis, treatment, prognosis, and prevention.Finally, a diagnosis flowchart has been formulated.The guideline aims to improve the standard diagnosis and treatment of food allergies in children in China.
RESUMEN
Exercise is medicine.Exercise is not only the cornerstone of children′s normal growth and development, but also the necessary condition of physical and mental health.Moreover, exercise contributes to the management of childhood asthma.Exercise prescription is an effective method for children with asthma, but there is no much experience in China, we should continuously explore and optimize it.Therefore, the level of physical activity could be improved in children with asthma.
RESUMEN
Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infection (LRTI) and hospitalizations in infants under 1 year of age, seriously jeopardizing infants′ health.Most hospitalizations (up to 80%) due to RSV-LRTI occur in otherwise healthy infants born at term.At present, no effective treatment and preventative measure against RSV is available domestically.Passive immunization with fully human long-acting monoclonal antibody Nirsevimab offers immediate protection for all infants experiencing their first RSV season with one shot, thus ushering in a new era of prevention of RSV infection among infants.
RESUMEN
With the emergence of new respiratory virus, it is more apparent for the vulnerability of population to respiratory viral infection.Non-pharmaceutical interventions (NPIs) for respiratory virus infection have become the main way to prevent corona virus disease 2019.Some studies had proven its effectiveness.In addition, the NPIs also significantly reduced the incidence and hospitalization rate of other respiratory disease in children.NPIs for respiratory virus infection in children have its particularity and challenge.In daily life, it is important to guide children how to do the NPIs, so as to protect susceptible children and reduce the disease burden in children′s health system.Therefore, the aerosol transmission, the specificity of the NPIs in children, and the impact on childhood respiratory diseases are described in this article, to improve the prevention of common respiratory diseases in children.
RESUMEN
Acute respiratory tract infection is the most common infectious disease in children, which seriously threatens children′s health.Rapid and accurate etiological diagnosis is of great significance for the clinical treatment and control of these diseases.Pathogen nucleic acid test was applied and became the main method of respiratory tract infection diagnosis for its high sensitivity and specificity.To regulate the application of pathogen nucleic acid amplification test in respiratory tract infection in children, improve the diagnosis level, expert consensus on nucleic acid amplification test of respiratory pathogens in children was prepared to guide the application and promote pathogens diagnosis ability.
