Since the introduction of a universal Japanese encephalitis (JE) vaccination program and urbanization, the incidence of JE has dramatically decreased in Korea. However, recent JE cases have occurred, predominantly among unvaccinated adults and with a shift in age distribution. Continuous surveillance of the seroprevalence of JE is required to establish a proper immunization policy in Korea. |
Advances in autoimmune encephalitis studies in the past 10 years have led to the identification of new syndromes and biomarkers that have transformed the diagnostic approach to the disorder. The disorder or syndrome has been linked to a wide variety of pathologic processes associated with the neuron-specific autoantibodies targeting intracellular and plasma membrane antigens. However, current criteria for autoimmune encephalitis... |
The introduction of the mumps vaccine has dramatically reduced the number of mumps cases, but outbreaks have recently occurred among highly vaccinated populations in developed countries. Epidemiological and clinical characteristics of patients with mumps admitted between 1989 and 2012 in a single hospital in Korea are described in the present study. We retrospectively evaluated inpatients with mumps between 1989 and 2012... |
Purpose : Antibody persistence after primary series of Haemophilus influenzae type b (Hib) vaccine and responses to boosters are seldom studied in Korean children. We performed this study to evaluate the antibody titer in relation to booster immunization of Hib vaccine in Korean children. Method : One hundred forty four children aged 12-23 months were enrolled in three university hospitals. The... |
Purpose : This study was conducted to validate enzyme immunoassay (EIA) for the quantitative measurement of human IgG antibodies specific for Haemophilus influenzae type b (Hib) capsular polysaccharide. Method : We evaluated specificity, repeatability, intermediate precision, accuracy, lower limit of quantification (LLOQ), and stability to validate standardized EIA for the quantitative measurement of human anti-polyribosylribitol phosphate (PRP) IgG antibodies. Results :... |
Purpose : Neonatal lupus is characterized by congenital complete heart block(CCHB), cutaneous rash, and laboratory abnormalities in infants born to mothers with systemic lupus erythematosus(SLE). This study aims to examine the incidence of CCHB and clinical outcome in neonates born to mothers with SLE. Methods : The study group consisted of 49 neonates, born from 57 pregnancies of 55 women with... |
Purpose : In order to evaluate the time of disappearance of cytomegalovirus(CMV) IgG antibodies from mothers, and the alteration of the positive rate of CMV IgG antibodies among preschool period children, we investigated the positive rate of CMV antibodies among preschool children. Methods : We studied 391 children who visited the Department of Pediatrics from March, 2001 to February, 2004. We... |
Purpose : Streptococcus pneumoniae serotype 6B and 6A are important pathogens in pneumococcal infections. It is commonly assumed that the 6B vaccines elicit antibodies cross-reacting with the 6A serotype and the cross-reactive antibodies protect against infections of 6A. To examine this assumption, we measured the opsonophagocytic capacity to serotype 6A and 6B in adults. Methods : Twenty-four adults were immunized... |
Purpose : Streptococcus pneumoniae is an important pathogen in children as well as in elderly people. The aim of this study was to assess the opsonization activity of pneumococal capsular antibody to seven serotypes in 23-valent pneumococcal polysaccharide vaccine before and after immunization in Korean children. Methods : Nine children from 24 to 49 months of age were immunized with 23-valent... |
Purpose : We investigated the spontaneous seroconversion rate of hepatitis B viral markers and predictive factors affecting seroconversion in children with chronic hepatitis B. Methods : The study population included 214 children diagnosed as chronic hepatitis B, with positive HBsAg, HBeAg and HBVDNA over six months, and all patients had a family history of chronic Hepatitis B. They were followed between... |
The presence of IgG, IgA and IgM antineutrophil cytoplasmic antibodies(ANCA) were inves-tigated in 32 children with Henoch-Schölein Purpura(HS purpura), in 14 children with HS pur-pura nephritis who were confirrned by renal biopsy and in 12 control children using flow cytom-etry(FASCan, Beckton-Dickinson, Co, USA) and indirect immunofluorescence technique(Sigma Diagnostics, USA). There were no evidence of IgG, IgA or IgM cytoplasmic ANCA(p-ANCA),... |
Purpose : Haemophilas influenzae type b is a significant pathogen in children and several v accines with different immunologic properties are clinically used. An individual produces oligoc-lonal anti-Hib-PS antibodies and the repertoire of human anti-HihPS Antibody (Ah) can be div- ided into two types by the structure of the light chain V region. Ah using A2-VK II gene product, which... |
Wegener's granulomatosis is a disease of unknown etiology that is characterized by the clinicopathologic complex of necrotizing granulomatous vasculitis of the upper and lower respiratory tract, glomerulonephritis, and variable degrees of small vessel vasculitis. Recently Antineutrophil Cytoplasmic Antibody (ANCA) has been reported to be a highly specific test for the diagnosis of Wegener's granulomatosis. We have experienced a patient of Wegener's... |
Mycobacteria cause diseases which occur the world over and whoich carry a considerable burden in morbidity, mortality and social problems. A battery of monoclonal antibodies specific for mycobacterial antigens would provide a useful tool for rapid diagnosis of mycobacterial diseases. Fourtenn monoclonal antibodies to perchloric acid soluble antigne of M. tuberculosis were produced. Immunoglobulin isotypes of monoclonal antibodies were ten... |
Mycobacteria causes disease which occur over the world. The development of reliable serological teset for the diagnosis of tuberculosis in humans has been complicated by the large degree of cross reactivitiy between antigens of Mycobacteria species can be used as a tool for serodiagnosis of tuberculosis. Fourteen monoclonal antibodies to perchloric acid extract antigen of M. bovis BCG were produced.... |
