    ABSTRACT: The incidence of necrotizing pneumococcal pneumonia has increased during the past two decades. We hypothothesized that increased pneumococcal load or augmented inflammatory cytokine production might lead to destructive pneumococcal lung disease. This study enrolled prospectively 0-18 year-old children with a diagnosis of community-acquired pneumonia with pleural effusion admitted to 6 medical centers during March 2010 to April 2012. Children were diagnosed with pneumococcal empyema if the pleural fluid tested positive for quantitative pneumococcal (lytA) detection by real-time polymerase chain reaction (RT-PCR). Pneumococcal empyema cases were further divided into four groups according to necrosis severity: 0) non-necrosis, 1) mild necrosis, 2) cavitation, and 3) bronchopleural fistula (BPF). Nasopharyngeal and pleural pneumococcal load, as well as proinflammatory cytokines (TNF-α, IL-1β, IL-6, IL-8), Th1-(IL-2, IFN-γ), Th2-(IL-4, IL-10), and Th17-cytokines (IL-17) in the pleural fluid were measured. Serotypes 19A and 3 accounted for 69.4% and 12.5% (respectively) of 72 cases of pneumococcal empyema. Pleural pneumococcal load was significantly higher in serotypes 19A and 3 infection than for other strains causing infection (P=0.006). There was a correlation between nasopharyngeal and pleural pneumococcal load (ρ=0.35; P=0.05). In multivariate ordinal logistic regression analysis, pleural pneumococcal load (adjusted odds ratio [aOR], 1.79; 95% confidence interval [CI], 1.03-3.06), and IL-8 (aOR, 2.64; 95% CI, 1.21-5.75) were independent factors associated with the severity of lung necrosis. Evolution of S. pneumoniae toward increased fitness in their interaction with host and exaggerated IL-8 expression may be responsible for the increase of necrotizing pneumococcal pneumonia.

    ABSTRACT: Few studies have focused on multidrug-resistant Acinetobacter baumannii (MDRAB) infection in neonates. The aim of this study was to investigate risk factors for mortality in neonates with MDRAB infection. This retrospective case-series study was conducted at the Children's Hospital of China Medical University, Taichung, Taiwan. All patients hospitalized between January 2010 and December 2013 in the neonatal intensive care unit (NICU) with MDRAB infections were reviewed. A total of 67 isolates from 59 neonatal patients were positive for MDRAB. Of the 67 isolates, 38 were from blood (56.72%), 16 from sputum (23.88%), seven from pus (10.45%), three from ascites (4.48%), two from cerebrospinal fluid (2.99%), and one from pleural fluid (1.49%). There were five episodes of MDRAB clusters consisting of 28 cases during the study period. The mortality rate due to MDRAB sepsis was 20.34% (12/59). The statistically significant risk factors for mortality due to MDRAB infection were being infected with MDRAB within 7 days of admission to the NICU, use of umbilical vein catheters, absolute neutrophil count < 1500/mm(3), platelet count < 100,000/mm(3), and a delay in initiating adequate antibiotic treatment. MDRAB infection is responsible for a high mortality rate among neonates in the NICU, especially in those who have neutropenia or thrombocytopenia. Infection control and appropriateness of the initial antimicrobial agent with colistin play an important role in reducing mortality. Copyright © 2014. Published by Elsevier B.V.

    ABSTRACT: Group B Streptococcus (GBS) is an important pathogen in neonates, pregnant women and non-pregnant adults with underlying diseases. There are few studies regarding GBS epidemiology in Asia. The aim of this study was to investigate serotype distribution and genetic correlation of GBS isolates.Methods Multiplex PCR assay and pulsed-field gel electrophoresis (PFGE) were performed on 126 invasive GBS strains from 126 patients (17 infants, 1 adolescent, 108 non-pregnant adults) and eight colonizing GBS isolates from pregnant women. Since serotype VI prevalence far exceeds that reported in prior studies, genetic relationship of isolates was analyzed by multilocus sequence typing (MLST).ResultsMost common serotype was Ib (n = 29), followed by V (n = 27), VI (n = 25), III (n = 21), II (n = 16), Ia (n = 15), and IX (n = 1). Serotype VI was also the leading type in infants with early onset disease (EOD) (3/8, 37.5%) and colonizing pregnant women (3/8, 37.5%). Among 25 serotype VI isolates tested, 14 were ST-1, 7 were ST-679, 3 were ST-678, 1 was ST-681 and distributed into 4 PFGE pulsotypes. ST-678, ST-679 and ST-681 were novel sequence types; ST-678 and ST-679 are single-locus variants of ST-1 that belongs to clonal complex (CC) 1.ConclusionsCC1 dissemination of serotype VI GBS thus emerges as a key invasive pathogen in infants and non-pregnant adults in Taiwan. Serotype prevalence of GBS must be continuously monitored geographically to guide prevention strategy of GBS vaccines.

    ABSTRACT: Background Community-acquired pneumonia (CAP) is the leading cause of hospitalization of children. Mycoplasma pneumoniae is one of the most common pathogens. The disease severity is diverse, and the diagnosis remains a challenge to clinical pediatricians. The aims of this study are to provide a nationwide surveillance of the epidemiology and clinical manifestations of community-acquired mycoplasma pneumonia (CAMP) in children in Taiwan. Methods The medical records of children enrolled by the Taiwan Pediatric Infectious Disease Alliance (TPIDA) project during 2010–2011 were reviewed. Hospitalized children with segmental or lobar pneumonia were included. The demographic, clinical, laboratory and radiographic data were analyzed. Nasopharyngeal swabs, pleural effusion, and serum were collected for multiplex viral and bacterial polymerase chain reaction (PCR), mycoplasma immunoglobulin M (IgM), or paired immunoglobulin G (IgG) titer. Results There were overall 127 children with CAMP. Among them, 16 (12.6%) children had PCR and IgM positivity, 74 (58.3%) children had a positive serologic study, 34 (27.8%) children had positive PCR detection, and three (2.4%) children had paired IgG above a four-fold increase. Enrolled patients were divided into two groups before and after the age of 5 years. Children younger than 5 years or younger had a significantly longer hospitalization, higher intensive care unit (ICU) admission rates, and more complications. They were more frequent to receive oxygen supplementation and even surgical intervention. The white blood cell counts and C-reactive protein levels were higher in children 5 years old or younger. Conclusion Mycoplasma pneumoniae is an important etiology of CAP in children 5 years or younger. They had a longer length of hospitalization, higher inflammatory responses, and more complications, compared to children older than 5 years.

    ABSTRACT: Staphylococcus aureus is a versatile bacterium, which can lead to various infectious diseases. Various molecular typing methods are applied to the evolution and epidemiology surveys of S. aureus, mostly for methicillin-resistant S. aureus (MRSA). However, methicillin-susceptible S. aureus (MSSA) is still an important pathogen, but their molecular typing is evaluated infrequently.

    ABSTRACT: This prospective study aimed to investigate the immune responses and safety of an influenza vaccine in vaccine-naïve infants aged 6-12 months, and was conducted from November 2010 to May 2011. Fifty-nine infants aged 6-12 months received two doses of trivalent inactivated influenza vaccine 4 weeks apart. Hemagglutination inhibition titers were measured 4 weeks after the two doses of study vaccine. Based on the assumption that a hemagglutination inhibition titer of 1:40 or greater against the antigen would be protective in adults, two doses of the study vaccine generated a protective immune response of 63.2% against influenza A(H1N1), 82.5% against influenza A(H3N2) and 38.6% against influenza B viruses in infants aged 6-12 months. The geometric mean fold rises against influenza type A and B viruses also met the European Medicines Agency criteria for flu vaccines. The solicited events within 7 days after vaccination were mild in intensity. No deaths or adverse events such as optic neuritis, cranial neuropathy, and brachial neuropathy or Guillain-Barre syndrome were reported. Two doses of inactivated influenza vaccine were well tolerated and induced a protective immune response against influenza in infants aged 6-12 months.

    ABSTRACT: Streptococcus dysgalactiae subsp. equisimilis (SDSE) is increasingly recognized as a human pathogen responsible for invasive infection and streptococcal toxic shock syndrome (STSS). The pathogen possesses virulence genes that resemble those found in Streptococcus pyogenes (GAS). We analyzed the association between these specific toxic genes, clinical presentations, and outcome in patients with SDSE infections. Patients (older than 18 years) with community-acquired invasive bacteremia caused by SDSE bacteremia who were undergoing treatment at China Medical University Hospital from June 2007 to December 2010 were included in this study. Multiplex polymerase chain reaction was performed to identify virulence genes of the SDSE isolates. Demographic data, clinical presentations, and outcome in patients with SDSE infections were reviewed and analyzed. Forty patients with 41 episodes of SDSE bacteremia were reviewed. The median age of the patients with SDSE infection was 69.7 years; 55% were female and 78% had underlying diseases. Malignancy (13, 33%) and diabetes mellitus (13, 33%) were the most common comorbidities. The 30-day mortality rate was 12%. Compared with the survivors, the non-survivors had a higher rate of diabetes mellitus (80% vs. 26%), liver cirrhosis (60% vs.11%), shock (60% vs.17%), STSS (60% vs. 8%), and a high Pittsburgh bacteremia score >4 (40% vs. 6%). Most isolates had scpA, ska, saga, and slo genes, whereas speC, speG, speH, speI, speK, smez, and ssa genes were not detected. speA gene was identified only in one patient with STSS (1/6, 17%). All isolates were susceptible to penicillin, cefotaxime, levofloxacin, moxifloxacin, vancomycin, and linezolid. In invasive SDSE infections, most isolates carry putative virulence genes, such as scpA, ska, saga, and slo. Clinical SDSE isolates in Taiwan remain susceptible to penicillin cefotaxime, and levofloxacin.

    ABSTRACT: Pediatric pyogenic liver abscess is uncommon. This study aimed to investigate the clinical characteristics, radiologic features, pathogens, duration of hospitalization, and management of pediatric pyogenic liver abscess. Pediatric patients with pyogenic liver abscess admitted to the China Medical University Hospital from 1995 to 2011 were reviewed. Their clinical characteristics, radiological features, laboratory data, clinical management, and outcomes were analyzed. Those with liver abscess due to the complication of oncologic disease were excluded. Fifteen patients were diagnosed with pyogenic liver abscess. Their most common symptoms were fever and abdominal pain. Eight (53.0%) had leukocytosis (>15000/μL) and elevated C-reactive protein (CRP) level (>10 mg/dL). The main imaging presentation was a single abscess in right lobe of the liver (13/15, 86.7%). Blood culture were mainly negative (12/15, 80.0%). Pathogenic microorganisms cultured from pus revealed Klebsiella pneumoniae (6/15, 40.0%) and Streptococcus spp. (6/15, 40.0%) as the two most common pathogens. Percutaneous abscess drainage followed by adequate parenteral antibiotics were effective interventions. Hospitalization of at least 2 weeks was needed in most cases. There were no mortalities. Pyogenic liver abscess should be considered in children presenting with fever, abdominal pain, and leukocytosis with a high CRP level. Most cases involve a single lesion on right lobe of the liver. K. pneumoniae and Streptococcus spp. are the two most common pathogens. Drainage with adequate antibiotics has significantly good response.

    ABSTRACT: Complications regarding pneumonia occur in children during hospitalization and treatment. The objective of this study is to identify the risk factors of progressive pneumonia in order to institute early appropriate therapy. This was a prospective study which involved the pediatric departments of seven medical centers in Taiwan. Children aged from 6 weeks to 18 years old, hospitalized with community-acquired pneumonia (CAP) from January 2010 to August 2011, were enrolled. Progressive pneumonia was defined by the deterioration of discharge diagnosis as compared to admission. Demographic, clinical, and laboratory variables, diagnosis, antimicrobial therapy, and pathogens were compared. Four hundred and two children were included and 57 (14.2%) had progressive pneumonia. Independent associated factors identified for the development of progressive disease, by multivariate logistic regression analysis, included the following, age < 2 years, pleural effusion as admission diagnosis, Hb < 10 g/dL, WBC count > 17,500/μL, tachypnea, and duration to defervescence > 3 days. Streptococcus pneumoniae was the main etiology for progressive pneumonia (57.9%). There was no difference in choice of initial parenteral antibiotics between groups of progressive and non-progressive pneumococcal pneumonia. We found six clinical factors for predicting progressive pneumonia. Further evaluation should be performed in hospitalized pneumonic children with persistent fever not responding to therapy within 72 hours. The initial parenteral antibiotics were not related to the progression of pneumococcal pneumonia.

    ABSTRACT: Thromboembolism presenting with malignancy is common in adults but rare in children. We describe the case of a 17-year-old boy admitted to our hospital with syncope. Computed tomography revealed thromboembolism in both the lungs. Magnetic resonance imaging found thromboembolism in the inferior vena cava and a large heterogeneous mass in the pelvis. Pelvic osteosarcoma was confirmed by computed tomography-guided biopsy. Despite intensive chemotherapy and local radiation, only transient response was noted, the tumor remaining unresectable. To our knowledge, this is the first reported case of simultaneous pulmonary and inferior vena cava thromboembolism secondary to pelvic osteosarcoma in children. We also emphasize syncope as a unique feature of pulmonary thromboembolism. Accordingly, thromboembolism should be kept in mind as the first manifestation of occult malignancy, even in children.

    ABSTRACT: Mycoplasma pneumoniae accounts for 10-30% of community-acquired pneumonia (CAP) in children. This study reveals the epidemiology and clinical manifestations of children with macrolide-resistant (ML(r) ) M. pneumoniae pneumonia in Taiwan. Respiratory tract specimens were collected from children hospitalized with CAP for evaluation via PCR followed by DNA sequencing for several point mutations related to the ML(r) character. Of the 412 specimens collected during the study period, 60 (15%) were positive for M. pneumoniae, 14 (23%) of which presented point mutation (all A2063G) in 23S rRNA. Clinical symptoms and chest X-ray findings between the ML(s) and ML(r) groups were not significantly different. However, the ML(r) group had longer mean duration of fever after azithromycin treatment (3.2 days vs. 1.6 days, P = 0.02) and significantly higher percentage of changing antibiotics for suspected ML(r) strain (42% vs. 13%, P = 0.04). Although 58% of children in the ML(r) group did not receive effective antibiotics, all children were discharged without sequelae. In conclusion, 15% of CAP in children is caused by M. pneumoniae and the macrolide-resistance rate is 23% in Taiwan. Despite ineffective antibiotics, children with ML(r) M. pneumoniae pneumonia recover completely. Pediatr Pulmonol. © 2012 Wiley Periodicals, Inc.

    ABSTRACT: BACKGROUND: Fungemia in preterm infants is associated with high mortality and morbidity. This study reports an outbreak of unusual fungemia in a tertiary neonatal intensive care unit (NICU). METHODS: Ten Candida pelliculosa bloodstream isolates were identified from six infants hospitalized in the NICU from February to March 2009. Environmental study was performed, and genetic relatedness among the 10 clinical isolates of C pelliculosa and six control C pelliculosa strains was characterized by randomly amplified polymorphic DNA assay. In vitro susceptibility of isolates to six antifungal agents was analyzed by broth microdilution method. Amphotericin B was given to infected infants and prophylactic fluconazole was prescribed to the other noninfected extremely low birth weight infants during the outbreak. RESULTS: Thrombocytopenia (platelet counts <100×10(9)/L) was the early laboratory finding in four infants. One of six patients died, making overall mortality 17%. Fluconazole, voriconazole, amphotericin B, and micafungin provided good antifungal activity. Cultures from the environment and hands of caregivers were all negative. Molecular studies indicated the outbreak as caused by a single strain. The outbreak was controlled by strict hand washing, cohort infected patients, confined physicians and nurses to take care of patients, prophylactic fluconazole to uninfected neonates, and proper management of human milk. CONCLUSION: The study demonstrated the clinical importance of emerged non-albicans Candida species in NICU. For unusual pathogen isolated from immunocompromised hosts, more attention should be paid to monitor the possibility of an outbreak.

    ABSTRACT: There is no national data on group B streptococcus (GBS) infection in Taiwan. We investigated incidence of maternal GBS colonization and neonatal GBS infection rate and clinical pictures of neonatal GBS infection to estimate the value of intrapartum chemoprophylactic strategy in Taiwan. From January 2004 to June 2005, a prospective study to estimate maternal colonization rate by maternal rectovaginal culture at six hospitals was conducted. Neonatal GBS infection rate based on inborn infants was calculated retrospectively from January 2001 to June 2005; clinical pictures of infants diagnosed with invasive GBS disease were reviewed. Maternal colonization rate of GBS was around 20% at hospital base, incidence of neonatal GBS infection was 1 per 1000 live births of infants born at hospitals. There were 221 infants with GBS infection: in 142, the disease occurred within 7 days of birth (early-onset disease, EOD), and in 79, it developed later (late-onset disease). Infantile EOD was more often seen in mothers with premature rupture of membrane, often accompanied by respiratory failure necessitating ventilator support. Infants with late-onset disease often manifested fever, leukopenia, thrombocytopenia, and meningitis. Fifteen infants died, mostly of EOD type (12 of 15). Risk factors of mortality included rescue at delivery room, leukopenia, thrombocytopenia, sepsis, respiratory distress, persistent hypertension of newborn, respiratory failure needing intensive respiratory support (intermittent mandatory ventilator and high frequency oscillatory ventilator), surfactant use, shock, and congenital heart diseases. We concluded that universal maternal rectovaginal culture of GBS with intrapartum antibiotic prophylaxis is an urgent call to reduce EOD and mortality because of GBS infection in neonates in Taiwan.

    ABSTRACT: Group B Streptococcus (GBS) (Streptococcus agalactiae) is an important pathogen in neonates, pregnant women, and adults with underlying disease. Fifty clinical isolates were collected during the period 2001-2004 and analyzed by multilocus sequence typing and capsular serotyping. The six major sequence types (STs) identified by multilocus sequence typing were ST1, ST12, ST19, ST17, ST23, and ST10. Five major clonal complexes (CCs) and one single ST (ST61) from 11 different STs were found. CC1 (n=14) was the most common one, followed by CC12 (n=13), CC19 (n=9), CC17 (n=7), and CC23 (n=6). The most common serotypes were serotype III, followed by Ib, V, Ia, and IV. The most invasive strains in adults belonged to ST1 (CC1) and serotype V, and those in neonates belonged to ST17 (CC17) and serotype III. In addition, ST19 was distributed in adults and neonates. These results are similar to those of previous reports, but some geographic differences were found, suggesting that limited clonal lineages play important roles in GBS-associated diseases worldwide. Continued tracking of GBS in the population through clinical isolates is important for epidemiologic investigations and vaccine development.

    ABSTRACT: Empiric antibiotics are frequently given for children with acute exudative tonsillitis. A few studies have investigated the causative agent of acute "exudative" tonsillitis in children to evaluate the necessity of antibiotic therapy. This study tried to explore the common causative agent of acute exudative tonsillitis among children. From April 2009 to March 2010, throat swabs were obtained and cultured for viruses and bacteria from children who visited the pediatric emergency rooms of two medical centers in central Taiwan with acute exudative tonsillitis. Demographic data and microbiological results were analyzed. A total of 294 children with acute exudative tonsillitis were enrolled during the 1-year prospective study, and 173 (58.8%) of them were younger than 7 years. Group A streptococci were isolated from only three (1.0%) children, and they were all older than 6 years. A total of 143 viruses were isolated from 140 (47.6%) children. Adenovirus (18.7%) and enterovirus (16.3%) were the most common viral etiologies, followed by influenza virus (5.4%), parainfluenza virus (5.1%), herpes simplex virus Type 1 (2.7%), and respiratory syncytial virus (0.3%). Group A streptococcus only contributed to a minimal portion of acute exudative tonsillitis. Routine or immediate antibiotic therapy for acute exudative tonsillitis in children is not necessary.

    ABSTRACT: Concomitant infections are frequent and usually the causes of death in patients with severe AA. HSCT can restore hematopoiesis in AA, but it is usually life threatening when patients simultaneously have an IFI. Mixed IFIs have been reported on rare occasions. The exact diagnosis of IFIs is difficult because of low fungus culture rate, difficultly obtaining tissue specimens in severely immunocompromised patients or those with bleeding tendencies. Otherwise, treatment with anti-fungal drugs alone for DMIFI was always lethal in previous reports. Surgical resection is crucial for invasive zygomycosis, but severe pancytopenia and bleeding tendency make therapy difficult. Herein, we report that with a combination of aggressive anti-fungal drugs, HSCT, and surgery, we successfully treated a 10-yr-old boy with severe AA and pulmonary zygomycosis before HSCT and disseminated mixed invasive zygomycosis and aspergillosis after HSCT.

    ABSTRACT: Community-acquired pneumonia (CAP) is one of the most common diseases during childhood, and its features vary between countries. Death from CAP is rare in industrialized countries, but it is the leading cause of mortality in developing countries. The purpose of this study was to determine the epidemiology and morbidity of pneumococcal CAP (PCAP) in children hospitalized with pneumonia in Taiwan. We retrospectively screened the medical records of 12,914 children hospitalized with pneumonia at four hospitals in Taiwan from 2000 to 2005. This included a suspected PCAP group (2350 patients) and a group with likely/definite pneumococcal pneumonia (PP group, 901 patients). From 2000, the frequency of suspected PCAP increased gradually every year, and peaked in 2003 (22.14%); while the proportion of likely/definite PP was highest in 2004 (9.75%). The likely/definite PP group accounted for 6.98% of the hospitalized pneumonia patients from 2000 to 2005. Of children hospitalized with pneumonia, 17.9% of the suspected PCAP group and 21.3% of the PP group were admitted to the intensive care unit (ICU). Twenty-three patients died (14 in the PCAP and 9 in the PP groups) and nine (5 in the PCAP and 4 in the PP groups) were discharged with sequelae. Our results indicate that children hospitalized with PCAP are common in Taiwan. About 20% of these children need ICU admissions, and some still have a poor outcome. Effective immunization programs with pneumococcal conjugate vaccine are needed for disease control and prevention.
