Purpose: Renal involvement is the most important prognostic factor of HSP. Therefore, the pathogenesis and prognostic factors in renal involvement have been studied by many researchers. The aim of this study was to evaluate the clinical risk factors and the role of TNF-$\alpha$ in renal involvement of HS purpura. Methods: The subjects of this study were 12 patients of HS purpura, 7 patients of HS nephritis, and 5 age-matched controls. We have analysed the rist factors for renal involvement in clinical symptoms and collected the sera and urines of all subjects in acute and convalescent stage. The concentration of TNF-$\alpha$ in the collected sera and urines were measured by sandwich ELISA and compared with that of age-matched controls. Results: Statistical analysis showed that persistent purpura increased the risk of developing renal involvement (P=0.0018). and serum TNF-$\alpha$ levels in the acute stage of patients with renal involvement($11.45{\pm}7.01$ pg/ml) were significantly higher than those of without renal involvement($6.32{\pm}1.31$pg/m1) and of age-matched controls($5.99{\pm}1.34$pg/m1)(P=0.012, 0.027, respectively). However, urine TNF-$\alpha$ levels have no correlation with renal involvement. On investigation of serum TNF-$\alpha$ levels in acute stage of HS purpura, persistent purpura had a significantly higher increase(P=0.038). Conclusion: Serum concentration of TNF-$\alpha$ is a risk factor and has a predictable value along with clinical risk factors, such as, persistent purpura for renal involvement in HS purpura. Also, the effectiveness of the specific treatment fur antagonizing TNF-$\alpha$ in HS nephritis may need further study.

Purpose : The Epstein-Barr virus(EBV), gamma herpesvirus, is an important pathogen that is widespread around the world. The EBV causes various diseases depending on the geographic location, and on the immunity or the premorbid condition of the person exposed to EBV. To evaluate EBV typing may be the most important step to figure out the pathogenesis of EBV associated diseases, and we need to re-evaluate the pathologic role of human leukocyte antigen(HLA) in developing Epstein- Barr virus associated acute infectious mononucleosis by using newly developed methods. Methods : This study included 24 children(age range : 6 to 13 years), serologically confirmed with acute infectious mononucleosis. The control group for the HLA type consisted of 200 age-matched healthy children. To classify HLA I, modified ARMs-PCR was used, while modified PCR-SSOP was utilized in typing of HLA II. Also, we performed EBV typing in study patients by using a one-step PCR. Results : The results of HLA types : In HLA class I, HLA-A24 was positive in 69 of 200 healthy children and positive in 14 of 24 patients in the study group(relative risk : 3.5724, chi-square; 5.26, P<0.05). In HLA class II, HLA-DRB1*07 was detected in 18 of 200 healthy children, and eight of 24 patients in the study group(relative risk; 506173, chi-square; 9.73, P<0.01). The results of EBV types : In the research group, 20(83.8%) of 24 patients were shedding type A virus, while 4(16.7%) were type B. Conclusion : We conclude that development of infectious mononucleosis may be associated with HLA types, and these results suggest that acute infectious mononucleosis could have hereditary traits. And we confirm that type A EBV is highly prevalent in patients with acute infectious mononucleosis in Korea. Also, our results suggest that further large scale studies, including adult groups, regarding the association between pathogenesis of EBV with HLA-DP or HLA-DQ will be warranted.

Purpose : Peritoneal dialysis (PD) is the major form of dialysis in use for infants and children with end-stage renal disease (ESRD). The aim of this study was to gain insight into the current status of children on PD in Korea. Methods : In May 2008, questionnaires were sent to the pediatric nephrologists via e-mail. Four centers replied and those data were reviewed. Results : A total of 103 patients were included in this study. Male to female ratio was 1.6:1. Mean age was $11.5{\pm}4.9$ years (0-19 years). Primary renal diseases diagnosed were as follows: primary glomerular disease (34%), chronic pyelonephritis-reflux nephropathy (14.6%), systemic disease (9.7%), renal hypoplasia/dysplasia (8.7%), heredofamilial disease (6.8%), vascular disease (3.9%), drug-induced nephropathy (1.0%), and unknown (12.6%). PD modalities were as follows: CAPD (42.7%), CCPD (27.2%), NIPD (11.7%), and Hybrid (18.4%). Weekly total Kt/V was $2.1{\pm}0.7$ (0.3-4.1). Results of peritoneal equilibrium test were as follows: low 36.8%, low average 31.6%, high average 19.7%, and high 11.8%. Z-score for weight was $-1.00{\pm}1.20$ (-4.54~+2.50). Z-score for height was $-1.55{\pm}1.65$ (-9.42~+1.87). Growth hormone was administered in 24.3% of patients. Anti-hypertensive drugs were administered in 64.0% of patients. Laboratory findings were as follows: hemoglobin $10.5{\pm}1.4$ g/dL, calcium $9.7{\pm}0.7$ mg/dL, phosphorus $5.4{\pm}1.4$ mg/dL, and parathyroid hormone $324.2{\pm}342.8$ pg/mL. Conclusion : Primary glomerular disease was the most common cause of ESRD. CAPD was the most prevalent PD modality. Low and low average peritoneal transport type were common. Growth disturbance were noted in many patients. Some patients had hypertension even with anti- hypertensive drugs. Calcium-phosphorus levels were maintained adequately, but many patients had secondary hyperparathyroidism.

Purpose : It has been suggested that the exposure to aeroallergens during early infancy after birth is important in the subsequent development of sensitization and allergic diseases. In Korea, the level of house dust mites as one of the important aeroallergens is known to be the highest in autumn. The aim of this study was to test whether the distribution of month of birth bears a relationship to the presence of mite sensitization in children with respiratory allergy. Methods : Skin prick tests and methacholine provocation tests were performed on 1,327 patients with chronic respiratory symptoms who visited Seoul National University Children's Hospital from January 1995 to May 2002. An analysis of patients' month of birth distribution according to the presence of mite sensitization was performed. Results : Atopic subjects who had at least one positive skin test numbered 864(65.1%); and non-atopic subjects numbered 463(34.9%). Among atopic subjects, 787(59.3%) had positive skin tests to mites and 77(5.8%) had positive skin test only to minor allergens. A significantly greater than expected number of mite atopic subjects were born in the months between August and November(P=0.03), however, the birth month of non-atopic subjects didn't show a consistent seasonal preference. Asthma patients numbered 543(40.9%). Among these, atopic asthmatics numbered 421(77.5%) and non-atopic asthmatics, 122(22.5%). Dust-mite atopic asthmatics numbered 387(91.9%) out of 421 atopic asthmatics. Dust-mite atopic asthmatics were born significantly higher in the season lasting from August to November in comparison to non-atopic asthmatics(P=0.002). Conclusion : Month of birth seems to be related with sensitization to allergens. Our results show that August to November is the risk period for the development of mite sensitization in Korea.

Purpose : Henoch-$Sch{\ddot{o}}nlein$ purpura(HSP) is a systemic vasculitis, characterized by cutaneous purpura, abdominal pain, arthralgia and renal involvement. The clinical features of HSP have been reasonably well documented but there are still many gaps in our understanding of HSP. The aim of this study was to present the clinical features of 125 children with HSP and compare them with previous reports, placing particular emphasis on clinical information. Methods : We collected the clinical data of 125 patients with acute HSP who visited Chungbuk National University Hospital from March 1992 to April 2002. Data were expressed as the mean or $mean{\pm}SD$ and statistical analysis was performed using Chi-square approximation. P<0.05 was considered as significant. Results : The patient population consisted of 87 boys and 38 girls ranging in age from one to 14 years. HSP occurs throughout the year, but this study shows seasonal skewing, with most patients presenting from fall through spring and a paucity of cases in summer. All patients had non-thrombocytopenic purpura concentrated on the buttocks and lower extremities. Purpuric lesions were also scattered on the arms and occaisionally on the face and ears, but the trunk was largely spared. A recurrence of purpura was defined as the reappearance of a rash or other symptoms following resolution of disease for at least two weeks. The mean number of recurrences was 0.51. Eighty eight patients(70.4%), 18 patients(14.4%) and 67 patients(53.6%) complained of abdomianl pain, gastrointestinal bleeding and arthralgia, respectively. Nephritis occurred in 48(38.4%) patients. Fifteen boys (17.2%) developed epididymitis. Neurologic features occurred in 13(10.4%) and two(15%) of these were seizures. Conclusion : HSP all showing purpura as defined is characterized by various clinical features, including abdominal pain, arthralgia, epididymitis and nephritis which could occur before the appearance of purpura. Therefore, we suggest that the possibility of HSP should be considered in children before invasive procedures, even if the above symptoms and signs present without purpura.

Purpose : We have studied the changes of cardiac troponin I(cTnI) level and left ventricular ejection fraction(LVEF) before and after treatment of IVGG to evaluate the efficacy of single high dose of intravenous gammaglobulin(IVGG)(2.0gm/kg) therapy for improving cardiac function and clinical symptoms and signs in patients with clinically suspected acute myocarditis. Methods : The patients consisted of 18 cases who admitted increased cTnI with clinically suspected acute myocarditis caused by viral infection, Kawasaki disease and fever unknown origin(FUO) from Jan. 1995 to Jun. 1998. The control group consisted of 20 cases suffered from hand-foot-mouth disease, herpangina and high fever with rash. The level of cTnI was measured by Chemiluminiscent immunoassay method(normal<0.1ng/ml) and cardiac function was evaluated by left ventricular ejection fraction(LVEF)(normal 64~83%) by echocardiogram. Results : The level of cTnI increased to $0.306{\pm}0.209ng/ml$ and LVEF decreased to $60.1{\pm}1.6%$ before treatment of IVGG significantly as compared with control group(P<0.05). All cases were returned to normal range of LVEF($71.4{\pm}3.7%$) and decreased cTnI significantly($0.089{\pm}0.082ng/ml$) after treated with IVGG within 1 week in patients group(P<0.05). Conclusion : The single high dose of IVGG(2.0gm/kg) therapy was rapid and effective improvement of cardiac function and clinical symptoms and signs of acute myocarditis, and the measurement of serum cTnI and LVEF may help to diagnose and evaluate efficacy of IVGG on it.

Purpose : We studied the value of clinical signs, laboratory findings and $^{99m}technetium$ dime-rcaptosuccinic acid(DMSA) scan in predicting the presence of vesicoureteral reflux(VUR) in children with first febrile urinary tract infection(UTI). Methods : A retrospective analysis of 84 hospitalized children with first febrile UTI was performed. They underwent DMSA scan and voiding cystourethrography(VCUG) during the acute phase, and were divided into three groups according to the results of the VCUG: absence of VUR, mild(grade I-II) and severe VUR(grade III-V). We studied the relation of VUR to age, gender, fever duration, causative organism, white blood cell count, serum C-reactive protein and result of DMSA scan. Results : Among 84 patients, 6 had mild and 17 had severe VUR. Thirty-eight had abnormal DMSA scan. results Patients with VUR were older than those without VUR(P<0.01). There was a lower probability of infection with Escherichia coli in patients with severe VUR than in those with mild and absent VUR(P<0.01). An abnormal DMSA scan correlated with the presence and severity of VUR(P<0.05). Severe VUR was present in 10.9% of patients with normal DMSA scan. The sensitivity, specificity, positive and negative predictive values of the DMSA scan in predicting the presence of VUR were 69.6%, 63.9%, 42.1%, and 84.8%, respectively. Conclusion : An abnormal DMSA scan correlated to the presence and severity of VUR, but the sensitivity, specificity and positive predictive value of the DMSA scan were low. There-fore, patient with an abnormal DMSA scan requires a VCUG. In order to prevent missing the 10.9% of patients with severe VUR but normal DMSA scans, a VCUG should be performed in patient with normal DMSA scan.
