Purpose: Hematopoietic cell transplantation (HCT) recipients are vulnerable to invasive infection by Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae (Sp). This study was performed to evaluate immune responses after Hib and Sp vaccination in Korean pediatric HCT recipients. Methods: Patients were prospectively enrolled at Samsung Medical Center during 2009-2011. ELISA tests to detect anti-PRP IgG antibody and antibodies to Sp serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F were performed at the Center for Vaccine Evaluation and Study, Ewha Medical Research Institute. Results: Ten patients (two allogeneic, eight autologous recipients) with median age 5.4 years (range 2.7-12.2 years) were enrolled. Before Hib vaccination, 60% of patients' anti-PRP IgG titers were below
. After vaccination, 100% of patients' anti-PRP IgG titers increased above
(cut-off value for detection) and
(cut-off value for seroprotection). For pneumococcus, in 2-5 year-old patients, pre-vaccination geometric mean concentrations (GMCs) of IgG for six serotypes (4, 6B, 9V, 14, 18C, and 23F) were below
and at 5 months post-vaccination GMCs of IgG for all seven serotypes increased to above
. In patients older than 5 years, pre-vaccination GMCs of IgG for four serotypes (4, 9V, 14, and 23F) were below
and at 3 months post-vaccination GMCs of IgG for all seven serotypes increased to above
. Conclusion: Most HCT recipients had low or no protective antibodies to Hib and Sp before vaccination, but showed good immune responses to protective levels after vaccination.

Purpose: The aim of this study is that the prevalence of rotavirus infection was evaluated by each group and clinical features of group A, B and C rotaviruses infections were described respectively to compare one with another. Methods: Between January 2010 and December 2010, we enrolled a group of children below 10 years of age admitted for management of acute diarrhea at the Catholic University of Korea Bucheon St. Mary's Hospital. A total of 310 stool samples documented to be free of common bacterial pathogens were collected from children with diarrhea. The presence of group A, B or C rotavirus is indicated by amplification of DNA segments of the expected lengths after the first and second PCRs Results: In a total of 310 stool specimens, 40 (12.9%) specimens were positive for rotaviruses. These included 23 (7.4%) positive for group A, 5 (1.6%) for group B and 12 (3.9%) for group C rotaviruses. Group B rotavirus infected patients had significantly less diarrheas per day (group A: P =0.01, group C: P =0.01) and shorter duration of vomiting days (group A: P =0.03, group C: P =0.03) than those with group A and C rotaviruses infection respectively. All the group B rotaviruses had been isolated in March and October. Group C rotavirus infections were prevalent during late summer and early winter and peaked in October. Conclusion: These findings indicate that group B and C rotaviruses are notable causes or the contributing causes of diarrhea among infants and children in Korea.

DOI : 10.14776/kjpid.2014.21.2.104
Purpose: We compared the clinical manifestations of patients with tsutsugamushi disease between children and adults. Methods: From January 2003 to December 2012, 768 patients diagnosed with tsutsugamushi disease were retrospectively reviewed, and the clinical characteristics, laboratory findings, and complications were compared between children and adults. Results: No patterns of annual increases in the number of patients were noted in both children and adults. The higher incidences occurred in October and November respectively. By gender, male outnumbered female in children, but the opposite trend was seen in adults. By residential area, the urban distribution of children was higher than that of adults. Rashes (P =0.001) and eschar (P =0.004) were more common in children, while myalgia was more common in adults. Children had a high prevalence of anemia (P =0.041), and low incidence rates of thrombocytopenia, abnormal liver and renal function. Children yielded better results in the duration of their hospital stay and the incidence of complications (P <0.001). A comparison of the therapeutic effects of doxycycline and macrolide antibiotics, which was performed only on the children, did not reveal any significant differences. Conclusion: Compared to adults, children had higher incidence rates of male patients and more often suffered from rashes and eschar. Children yielded better results in the laboratory findings and duration of the hospital stay and complications. Therefore, when children are suspected to have tsutsugamushi disease, especially during its peak occurrence period, detailed physical examination and serological test should be performed to ensure a prompt diagnosis, and the use of macrolide antibiotics, which have fewer side effects, is expected to yield the same therapeutic effects.

Purpose: The objective of this study was to assess and investigate the epidemiology of pertussis in infants under 6 months of age. Methods: A prospective study was conducted between October 1, 2011 and April 30, 2013 in CHA Bundang Medical Center, Seongnam, South Korea. Polymerase chain reaction (PCR) or culture was used to detect Bordetella pertussis in nasopharyngeal aspirates from case patients who were hospitalized for acute lower respiratory tract infection (LRTI). In addition, multiplex real-time PCR assays were also performed to detect 6 etiologic viruses, including adenovirus, human metapeumo-virus, influenza virus, parainfluenza virus, respiratory syncytial virus and rhinovirus. Results: Of the 79 enrolled case patients, whose median age was 2 months of age, the most common diagnoses uncovered in this study were acute bronchiolitis (60%) and pneumonia (28%). B. pertussis infection was found in 13 cases (16%), in which 7 (53%) was coinfected with respiratory syncytial virus and 1 (7%) with influenza A virus. Of the 13 patients with B. pertussis infection, 6 (46%) were not vaccinated with the diphtheria, tetanus toxoid, and acellular pertussis vaccine, while 6 (46%) received 1 dose, and 1 (8%) received 2 doses. Conclusion: B. pertussis infection was present in 16% of under 6 month-old infants, who were hospitalized for acute LRTI. Therefore, a nationwide epidemiological surveillance of pertussis, including institutions that cater to infants under 6 months of age is necessary and needed.

Purpose: To compare the clinical characteristics and laboratory finding between adenoviral and group A streptococcal (GAS) pharyngitis. Methods: A retrospective review of medical records was performed in the patients with adenovirus infection among those who were admitted for febrile respiratory disease from January 2011 to July 2013 and GAS pharyngitis among those who visited for symptoms of scarlet fever from August 2006 to July 2013. Results: 179 patients (AV1 group) were diagnosed with adenoviral pharyngitis and 37 (AV2 group) of these patients had adenovirus single infection. 26 patients (GAS group) were diagnosed with scarlet fever. Adenoviral infection (AV2 group) developed in younger patients compared to GAS group (
years, P =0.000). Total durations of fever and admission were longer in AV2 (
days, P =0.000;
days, P =0.000, respectively). WBC counts were higher in AV2 (
, P =0.000). CRP was not significantly different between AV2 and GAS group (
mg/dL, P =0.368). No difference was found between two groups in the percentage of antibiotics use (91.9% vs. 100%, P =0.261). Conclusion: Clinical characteristics and measures of inflammation in the laboratory findings were similar between adenoviral and GAS pharyngitis group. It is necessary to conduct the test for respiratory virus and bacteria in early stage to differentiate in the pharyngitis patients with leukocytosis and elevation of CRP level.

Purpose: Streptococcus pyogenes is an important cause of invasive diseases in children. We aimed to describe the clinical characteristics of invasive infections due to S. pyogenes in children in Korea. Methods: A retrospective study of children under 18 years of age with invasive infections due to S. pyogenes at Seoul National University Children's Hospital between March 1992 and December 2012, and Seoul National University Bundang Hospital between March 2003 and December 2012 was conducted. Demographic factors, clinical characteristics, laboratory findings, treatment, mortality and morbidity of all patients were reviewed. Results: A total of 30 among 36 cases identified as invasive disease due to S. pyogenes were available for review. There was a predominance for male subjects (male:female=2.75:1). The median age was 50 months (range 12 days to 15 years) and 53.3% were under 5 years of age. Skin and soft tissue infections (9/30, 30.0%), bacteremia without identified focus (4/30, 13.3%) and bone and joint infections (6/30, 20.0%) were the most frequent clinical presentations. Streptococcal toxic shock syndrome (3/30, 10.0%) pulmonary, abdomen and central nervous system infections (2/30, 6.7%) were also seen. There was a peak in number of patients in year 2012 (9/30, 30.0%). There were no cases of mortality. Erythromycin and clindamycin resistance rates were low by 3.8% and 7.5%, respectively. Conclusion: We studied the clinical presentations of invasive infections due to S. pyogenes during the past 20 years in Korean children. The findings of this study help us understand the characteristics of the disease, enhancing early recognition and prompting adequate antibiotic therapy which is important in reducing morbidity and mortality.

Acute otitis media (AOM) is one of the most common childhood infectious diseases. Despite antibiotic treatment for AOM, AOM and its complication still continue to develop. Acute mastoiditis is a serious complication of AOM and epidural abscess constitutes the commonest of all intracranial complication of AOM. Neurological complication of acute mastoiditis are rare but can be life threatening. Their presentation may be masked by the use of antibiotics. We report the rare case of acute otitis media progressing to acute mastoiditis, epidural abscess formation and lateral sinus thrombophlebitis caused by Streptococcus pneumoniae in a child. She was admitted with acute otitis media with fever. Despite proper antibiotics, acute mastodititis and epidural abscess were developed, and after surgical drainage and antibiotics therapy she was recovered without sequalae.

Despite its rare occurrence, early diagnosis and appropriate treatment for neonatal herpes simplex virus infection are mandatory due to its high morbidity and mortality. In Korea, there has been no epidemiologic data on neonatal herpes simplex virus infection, and even case reports are rare. We observed a 16-day-old neonate who presented with fever and seizures. We diagnosed her with meningoencephalitis caused by herpes simplex virus type 2 based on the polymerase chain reaction test, and treated her with intravenous acyclovir and anticonvulsants. The seroprevalence of herpes simplex virus type 2 sharply increases in women in their 30s, and the average age for childbirth has increased to older than 30 years of age in Korea; we therefore expect that the incidence of neonatal herpes simplex virus type 2 infection will rise in Korea, and more attention should be directed to neonatal herpes simplex virus type 2 infection. We report this newborn patient's case along with a literature review.
