RESUMO
Objective:To analyze the patterns of antibacterial agents in Chinese children surveyed by the China multi-center monitoring network for the application of antibacterial agents in children and neonates in 2019 by using World Health Organization (WHO) Access, Watch, Reserve and Not-recommended (AWaRe) and typical anatomical/therapeutic/chemical (ATC) in this study.Methods:The cross-sectional method was adopted.A multi-center cross-sectional survey was conducted on one day from September to December 2019.The information of all inpatients taking antibiotics was uploaded to the network-based data collection system (https: //garpec-31.mobilemd.cn/login.aspx? relogin=true). This study covered 13 hospitals from 10 provinces and cities in China.All hospitalized children in the Respiratory Department, Infectious Disease Department, General Surgery Department, Pediatric Intensive Care Units, Neonatal Intensive Care Units and Neonatology joined in this survey.The clinically used antibacterial agents were classified by AWaRe and ATC, and the AWaRe and ATC distributions of antibacterial agents prescribed for Chinese children and neonates were described.Results:Of the 2 644 antibiotic prescriptions included from 13 hospitals, 2 134 (80.71%) were for children and 510 (19.29%) were for neonates.Of all antibiotic prescriptions, there were 368 (13.92%) Access antibiotics prescriptions, 1 973 (74.62%) Watch prescriptions, 60 (2.27%) Reserve prescriptions and 243 (9.19%) Not-recommended prescriptions.The top-five antibiotics prescribed for children and neonates were third-generation cephalosporins (1 056, 39.94%), macrolides (492, 18.61%), carbapenems (275, 10.40%), beta lactam-beta lactamase inhibitors (246, 9.30%), and second-generation cephalosporins (136, 5.14%). The use ratios of Access, Watch, Reserve and Not-recommended antibiotics in each center ranged from 0 to 30.00%, 36.67% to 97.20%, 0 to 17.02% and 0 to 33.33%, respectively.In 1 360 antibiotic prescriptions for children and neonates with pneumonia, there were 152 (11.18%) Access antibiotics, 1 051 (77.28%) Watch antibiotics, 37 (2.72%) Reserve antibiotics, and 120 (8.82%) Not-recommended antibiotics.The top-five antibiotics prescribed for children with pneumonia were third-generation cephalosporins (522, 38.38%), macrolides (388, 28.53%), beta lactam-beta lactamase inhibitors (141, 10.37%), carbapenems (117, 8.6%) and penicillins (49, 3.60%).Conclusions:Watch antibiotics and broad spectrum antibiotics such as third-generation cephalosporins and macrolides prone to induce resistance are the main antibacterial agents used in Chinese children and neonates with pneumonia.Broad-spectrum antibiotics may be overused in Chinese children and neonates.
RESUMO
Objective To summarize the clinical characteristics and outcome of infants with group B streptococcus (GBS) blood stream infection.Methods The medical records of 55 cases with GBS blood stream infection who were hospitalized in Shenzhen Children′s Hospital from 1st January 2010 to 31st December 2015 were retrospectively analyzed.Results There were 30 boys and 25 girls in this study.The age ranged from 1 hour to 78 days.Six cases (10.9%) were early-onset and 49 cases (89.1%) were late-onset.Forty cases (72.7%) were neonates and 15 cases were infants.The meningitis was diagnosed in 20 patients (36.4%).Peripheral white blood cell (WBC) counts declined in 10 cases (18.2%), and elevated in 32 (58.2%) cases.Increased levels C-reactive protein were found in 41 cases (74.5%).All of isolates were susceptible to penicillin, ampicillin, linezolid and vancomycin, while the resistance rates to erythromycin, clindamycin, tetracycline and ciprofloxacin were 56.6% (30/53), 77.4% (41/53), 98.1% (52/53), and 1.9% (1/53), respectively.Meropenem was used in 18 cases, and penicillins or cephalosporins were used in 37 cases.Combined therapy with linezolid was used in 13 cases, combined therapy with vancomycin was used in 3 cases, and combined therapy with two kinds of antibiotics was used in 37 cases (67.3%).In clinical outcome analysis, 54 children (98.2%) were improved and 1 child (1.8%) died of complicated multiple organ dysfunction syndrome and intracranial hemorrhage.Conclusions GBS blood stream infection occurs commonly in the infants aged younger than 3 months, more than one third cases complicated with purulent meningitis.All of isolates are susceptible to penicillin, while the resistant rates are high to erythromycin and clindamycin.The percentage of combination therapy is high.The outcomes are not good.
RESUMO
Objective To investigate the distribution of pathogens isolated from clinical samples and the resistance to the com‐mon antimicrobial agents .Methods Of the 3 745 children ,Hand‐foot‐mouth disease was the most prevalent disease with 1 397 (37 .30% ) cases ,followed by the bronchopneumonia ,rotavirus enteritis and bacterial intestinal infection ;784 strains were isolated from the samples mainly including Haemophilus parainfluenzae (16 .20% ) ,Streptococcus pneumoniae (14 .92% ) ,Moraxella ca‐tarrhalis (12 .88% ) ,Staphylococcus aureus (10 .59% ) and Salmonella enterica(10 .8% ) ;The positive rate of Methicillin‐resistance Staphylococcus aureus(MRSA) was 27 .50% and the ESBLs producing Escherichia coli and Klebsiella pneumoniae were 46 .43%and 81 .40% ,and two or more pathogens could be isolated from sputum .Conclusion Haemophilu ,Streptococcus pneumonia and Moraxella catarrhalis are the main bacterial pathogens in the department of infectious .There is a certain resistance to the common antimicrobial agents .It is important for us to focus on the pathogens and we should pay more attention to the control the resistance of the bacteria .
