RESUMEN
This study utilized a prospective, large-sample, multi-center, and registered key specialty approach of hospitals to monitor the application of Reduning Injection. A total of 100 249 adolescent patients aged 14 years and below who received Reduning Injection were monitored, resulting in 83 cases of adverse events, with 76 of them being classified as adverse drug reaction(ADR). The calculated incidence rate of ADR for Reduning Injection was 0.076%, indicating a very rare ADR. The main symptoms of ADR were pruritus, diarrhea, abdominal pain, vomiting, high fever, dyspnea, convulsion, and chills. All ADR cases were reported for the first time, including three new ADR cases and 73 known ADR cases. The categories of ADR was general ADR. All ADR was mild in severity. There were more males than females in ADR patients. One patient had a history of ADR, and the drug causing ADR was buprofen. The largest number of ADR cases occurred when the dosage of Reduning injection was 5-10 mL. The dropping speed was 30 drops or less per min, and the solvent type was 5% glucose injection. The most common manifestation of ADR patients was pruritus, followed by diarrhea, abdominal pain, vomiting, high fever, dyspnea, convulsions, and chills. 72 patients(94.74% of ADR patients) discontinued the drug, and three patients(3.95% of ADR patients) were given oxygen inhalation. 47 cases(61.84% of ADR patients) were treated with medication, of which dexamethasone was the most used(24 cases, 46.15% of ADR patients). 76 ADR patients were cured or improved. ADRs are more likely to occur when diagnosed with acute bronchitis by western medicine and cough by traditional Chinese medicine(TCM), TCM syndrome type is wind heat syndrome, and the combination medicine is ambroxol hydrochloride and bromhexine hydrochloride injection, ascorbic acid/vitamin C injection. This result provides an evidence-based safety basis for active pharmacovigilance of Reduning Injection in adolescents aged 14 years and below.

OBJECTIVES: To investigate the clinical characteristics and prognosis of pneumococcal meningitis (PM), and drug sensitivity of Streptococcus pneumoniae (SP) isolates in Chinese children. METHODS: A retrospective analysis was conducted on clinical information, laboratory data, and microbiological data of 160 hospitalized children under 15 years old with PM from January 2019 to December 2020 in 33 tertiary hospitals across the country. RESULTS: Among the 160 children with PM, there were 103 males and 57 females. The age ranged from 15 days to 15 years, with 109 cases (68.1%) aged 3 months to under 3 years. SP strains were isolated from 95 cases (59.4%) in cerebrospinal fluid cultures and from 57 cases (35.6%) in blood cultures. The positive rates of SP detection by cerebrospinal fluid metagenomic next-generation sequencing and cerebrospinal fluid SP antigen testing were 40% (35/87) and 27% (21/78), respectively. Fifty-five cases (34.4%) had one or more risk factors for purulent meningitis, 113 cases (70.6%) had one or more extra-cranial infectious foci, and 18 cases (11.3%) had underlying diseases. The most common clinical symptoms were fever (147 cases, 91.9%), followed by lethargy (98 cases, 61.3%) and vomiting (61 cases, 38.1%). Sixty-nine cases (43.1%) experienced intracranial complications during hospitalization, with subdural effusion and/or empyema being the most common complication [43 cases (26.9%)], followed by hydrocephalus in 24 cases (15.0%), brain abscess in 23 cases (14.4%), and cerebral hemorrhage in 8 cases (5.0%). Subdural effusion and/or empyema and hydrocephalus mainly occurred in children under 1 year old, with rates of 91% (39/43) and 83% (20/24), respectively. SP strains exhibited complete sensitivity to vancomycin (100%, 75/75), linezolid (100%, 56/56), and meropenem (100%, 6/6). High sensitivity rates were also observed for levofloxacin (81%, 22/27), moxifloxacin (82%, 14/17), rifampicin (96%, 25/26), and chloramphenicol (91%, 21/23). However, low sensitivity rates were found for penicillin (16%, 11/68) and clindamycin (6%, 1/17), and SP strains were completely resistant to erythromycin (100%, 31/31). The rates of discharge with cure and improvement were 22.5% (36/160) and 66.2% (106/160), respectively, while 18 cases (11.3%) had adverse outcomes. CONCLUSIONS: Pediatric PM is more common in children aged 3 months to under 3 years. Intracranial complications are more frequently observed in children under 1 year old. Fever is the most common clinical manifestation of PM, and subdural effusion/emphysema and hydrocephalus are the most frequent complications. Non-culture detection methods for cerebrospinal fluid can improve pathogen detection rates. Adverse outcomes can be noted in more than 10% of PM cases. SP strains are high sensitivity to vancomycin, linezolid, meropenem, levofloxacin, moxifloxacin, rifampicin, and chloramphenicol.

BACKGROUND: Streptococcus pneumoniae (S. pneumoniae) is a major cause of bacterial meningitis, septicemia and pneumonia in children. Inappropriate choice of antibiotic can have important adverse consequences for both the individual and the community. Here, we focused on penicillin/cefotaxime non-susceptibility of S. pneumoniae and evaluated appropriateness of targeted antibiotic therapy for children with IPD (invasive pneumococcal diseases) in China. METHODS: A multicenter retrospective study was conducted in 14 hospitals from 13 provinces in China. Antibiotics prescription, clinical features and resistance patterns of IPD cases from January 2012 to December 2017 were collected. Appropriateness of targeted antibiotics therapy was assessed. RESULTS: 806 IPD cases were collected. The non-susceptibility rates of S. pneumoniae to penicillin and cefotaxime were 40.9% and 20.7% respectively in 492 non-meningitis cases, whereas those were 73.2% and 43.0% respectively in 314 meningitis cases. Carbapenems were used in 21.3% of non-meningitis cases and 42.0% of meningitis cases for targeted therapy. For 390 non-meningitis cases with isolates susceptible to cefotaxime, vancomycin and linezolid were used in 17.9% and 8.7% of cases respectively for targeted therapy. For 179 meningitis cases with isolates susceptible to cefotaxime, vancomycin and linezolid were prescribed in 55.3% and 15.6% of cases respectively. Overall, inappropriate targeted therapies were identified in 361 (44.8%) of 806 IPD cases, including 232 (28.8%) cases with inappropriate use of carbapenems, 169 (21.0%) cases with inappropriate use of vancomycin and 62 (7.7%) cases with inappropriate use of linezolid. CONCLUSIONS: Antibiotic regimens for IPD definite therapy were often excessive with extensive prescription of carbapenems, vancomycin or linezolid in China. Antimicrobial stewardship programs should be implemented to improve antimicrobial use.

BACKGROUND: Invasive S. pyogenes diseases are uncommon, serious infections with high case fatality rates (CFR). There are few publications on this subject in the field of pediatrics. This study aimed at characterizing clinical and laboratory aspects of this disease in Chinese children. PATIENTS AND METHODS: A retrospective study was conducted and pediatric in-patients with S. pyogenes infection identified by cultures from normally sterile sites were included, who were diagnosed and treated in 9 tertiary hospitals during 2010-2017. RESULTS: A total of 66 cases were identified, in which 37 (56.1%) were male. The median age of these patients, including 11 neonates, was 3.0 y. Fifty-nine (89.4%) isolates were determined from blood. Fever was the major symptom (60/66, 90.9%) and sepsis was the most frequent presentation (64/66, 97.0%, including 42.4% with skin or soft tissue infections and 25.8% with pneumonia. The mean duration of the chief complaint was (3.8 ± 3.2) d. Only 18 (27.3%) patients had been given antibiotics prior to the hospitalization. Among all patients, 15 (22.7%) developed streptococcal toxin shock syndrome (STSS). No S. pyogenes strain was resistant to penicillin, ceftriaxone, or vancomycin, while 88.9% (56/63) and 81.4% (48/59) of the tested isolates were resistant to clindamycin and erythromycin respectively. Most of the patients were treated with ß-lactams antibiotics and 36.4% had been treated with meropenem or imipenem. Thirteen (19.7%) cases died from infection, in which 9 (13.6%) had complication with STSS. CONCLUSIONS: Invasive S. pyogenes infections often developed from skin or soft tissue infection and STSS was the main cause of death in Chinese children. Ongoing surveillance is required to gain a greater understanding of this disease.

BACKGROUND AND OBJECTIVE: Haemophilus influenzae (HI) is a common cause of community-acquired pneumonia in children. In many countries, HI strains are increasingly resistant to ampicillin and other commonly prescribed antibiotics, posing a challenge for effective clinical treatment. This study was undertaken to determine the antibiotic resistance profiles of HI isolates from Chinese children and to provide guidelines for clinical treatment. METHODS: Our Infectious Disease Surveillance of Pediatrics (ISPED) collaboration group includes six children's hospitals in different regions of China. The same protocols and guidelines were used by all collaborators for the culture and identification of HI. The Kirby-Bauer method was used to test antibiotic susceptibility, and a cefinase disc was used to detect ß-lactamase activity. RESULTS: We isolated 2073 HI strains in 2016: 83.9% from the respiratory tract, 11.1% from vaginal secretions, and 0.5% from blood. Patients with respiratory isolates were significantly younger than nonrespiratory patients (P < 0.001). Of all 2073 strains, 50.3% were positive for ß-lactamase and 58.1% were resistant to ampicillin; 9.3% were ß-lactamase-negative and ampicillin-resistant. The resistance rates of the HI isolates to trimethoprim-sulfamethoxazole, azithromycin, cefuroxime, ampicillin-sulbactam, cefotaxime, and meropenem were 71.1%, 32.0%, 31.2%, 17.6%, 5.9%, and 0.2%, respectively. CONCLUSIONS: More than half of the HI strains isolated from Chinese children were resistant to ampicillin, primarily due to the production of ß-lactamase. Cefotaxime and other third-generation cephalosporins could be the first choice for the treatment of ampicillin-resistant HI infections.
RESUMEN
OBJECTIVE: To study the clinical characteristics, drug sensitivity of isolated strains, and risk factors of drug resistance in children with invasive pneumococcal disease (IPD). METHODS: The clinical characteristics and drug sensitivity of the isolated strains of 246 hospitalized children with IPD in nine grade A tertiary children's hospitals from January 2016 to June 2018 were analyzed. RESULTS: Of the 246 children with IPD, there were 122 males and 124 females. Their ages ranged from 1 day to 14 years, and among them, 68 (27.6%) patients were less than 1 year old, 54 (22.0%) patients were 1 to 2 years old, 97 (39.4%) patients were 2 to 5 years old, and 27 (11.0%) patients were 5 to 14 years old. Pneumonia with sepsis was the most common infection type (58.5%, 144/246), followed by bloodstream infection without focus (19.9%, 49/246) and meningitis (15.0%, 37/246). Forty-nine (19.9%) patients had underlying diseases, and 160 (65.0%) had various risk factors for drug resistance. The isolated Streptococcus pneumoniae strains were 100% sensitive to vancomycin, linezolid, moxifloxacin, and levofloxacin, 90% sensitive to ertapenem, ofloxacin, and ceftriaxone, but had a low sensitivity to erythromycin (4.2%), clindamycin (7.9%), and tetracycline (6.3%). CONCLUSIONS: IPD is more common in children under 5 years old, especially in those under 2 years old. Some children with IPD have underlying diseases, and most of the patients have various risk factors for drug resistance. Pneumonia with sepsis is the most common infection type. The isolated Streptococcus pneumoniae strains are highly sensitive to vancomycin, linezolid, moxifloxacin, levofloxacin, ertapenem, and ceftriaxone in children with IPD.

OBJECTIVES: The treatment of acute herpangina is inconsistent. We aim to evaluate the effectiveness and safety of interferon α-2b spray versus Ribavirin for this disease. METHODS: A randomized, controlled trial was conducted in eight hospitals in China between 2016 and 2018. 668 patients (1-7 years old) were randomized into an experimental group (treated with Interferon α-2b spray) or control group (received Ribavirin Aerosol). Body temperature returning to normal within 72 h and remaining so for 24 h was the primary outcome; release of oral herpes and adverse events were the secondary outcomes. RESULTS: (1) The average age of onset was 2.5 years old. (2) After 72 h treatment, body temperature of 98.5% patients in experimental group and 94.3% in control group returned to normal and remained so for 24 h (P = 0.004). The differences were greater at 48 h treatment (95.2% vs. 85.9%, P < 0.001) and at 24 h (77.5% vs. 66.5%, P = 0.001). (3) The rate of improved oral herpes in the experimental group was higher than that in control group (46.7% vs.37.1%, P = 0.011). No adverse reaction occurred. CONCLUSIONS: Local application of recombinant interferon α-2b spray showed better efficacy for acute herpangina in children. It was safe for use.

BACKGROUND: Herpangina is a common infectious disease in childhood caused by an enterovirus. This consensus is aiming to standardize and improve herpangina prevention and clinical diagnosis. METHODS: The Subspecialty Group of Infectious Diseases, the Society of Pediatric, Chinese Medical Association and Nation Medical Quality Control Center for Infectious Diseases gathered 20 experts to develop the consensus, who are specialized in diagnosis and treatment of herpangina. RESULTS: The main pathogenic serotypes of herpangina include Coxsackievirus-A, Enterovirus-A and Echovirus. Its diagnosis can be rendered on the basis of history of epidemiology, typical symptoms, characteristic pharyngeal damage and virological tests. The treatment is mainly symptomatic, and incorporates topical oral spray with antiviral drugs. The course of herpangina generally lasts 4-6 days with a good prognosis. CONCLUSION: The consensus could provide advices and references for the diagnosis, treatment and management of herpangina in children.

OBJECTIVE: To explore the clinical characteristics and etiology of bacterial meningitis (BM) in Chinese children. METHOD: BM cases in children 28days to 18 years old were collected from January 2014-December 2016 and screened according to World Health Organization standards. Clinical features, pathogens, and resistance patterns were analyzed. RESULTS: Overall, 837 cases were classified into five age groups: 28 days-2 months (17.0%), 3-11 months (27.8%), 12-35 months (24.0%), 3-6 years (13.9%), and >6years (17.3%). Major pathogens were Streptococcus pneumoniae (S. pneumoniae, n=136, 46.9%), group B Streptococcus (GBS, n=29, 10.0%), and Escherichia coli (E. coli, n=23, 7.9%). In infants <3 months old, GBS (46.5%) and E. coli (23.3%) were most common; in children >3 months old, S. pneumoniae (54.7%), which had a penicillin non-susceptibility rate of 55.4% (36/65), was most frequent. The resistance rates of S. pneumoniae and E. coli to cefotaxime and ceftriaxone were 14.0%/40.0% and 11.3%/68.4%, respectively. All GBS isolates were sensitive to penicillin. CONCLUSIONS: The occurrence of BM peaked in the first year of life, while S. pneumoniae was the predominant pathogen in children >3months of old. The antibiotic resistance of S. pneumoniae was a concern.
