Purpose : Kawasaki Disease(KD) is a febrile disease with acute multisystemic vasculitis which is seen commonly in early childhood. The cause and etiologic agents are still unknown to identify using ordinary bacterial and viral culture, but the clinical labaratory studies suggest that KD is one of autoimmune disorder caused by infectious agents, but that is not proved yet. The study was performed to investigate the IgG subclasses in acute stage of KB before treatment of IVIG(Intravenous immunoglobulin). Method : The 35 cases in acute stage of KD before treatment of IVIG who were hospitalized from jan. 1995 to dec. 1996. The obtained sera were measured level of total IgG, IgM, IgA, IgE and IgG subclasses IgGl, IgG2, IgG3, IgG4 by using EIA and SRID method. Results : 1) The sex ratio is male to female is 1.5: 1.0, and male is prone to infected. 2) Total IgG, IgM, IgA and IgE level is normal range with age adjusted, but few cases are shown slight high level of total IgG compare to normal range of age adjusted. 3) acute phage reactants such as CRP, C3, ESR are all increased in acute stage of cases. 4) IgG subclasses IgGl, IgG2, IgG3 are shown normal range of age adjusted, but remarkably low level of IgG4 in all of cases. Conclusions : The low level of IgG4 is able to increasing the incidence of KD, and may use early diagnostic tools combine with other clinical symptoms and signs. But the resulsts of reported studies are different to each other, so it needs more times and cases to get final evaluation of changes of serum immnunoglobulin levels correlate to increase the incidence of high risk group of KD patients.

One of the chief characteristics of the retrovirus life cycle is the appearance of provirus caused by integration of viral genome into the host cell genome, and its delivery stably to the next generation as a part of host germ line. This stable form is called endogenous retrovirus (ERV) and expressed by exogenous or endogenous factors. HERVs and MuERVs are present in humans and mice correspondingly, and their expressions frequently cause diseases. Several diseases such as cancer, autoimmunity and neurological disorders are related with HERVs. Therefore, various strategies should be established for the development of effective therapies for the suffering patients.

당뇨병환자에서의 감염증은 인슐린과 항균제의 사용으로 그 이환율과 사망률이 현저히 감소하였으나, 현재까지 당뇨병환자의 진료에 있어서 해결해야 할 중요한 문제로 남아있다. 당뇨병환자에서 감염증의 발생빈도는 대부분 일반인과 차이가 없다고 보고되고 있으나 일부 특정 감염증의 빈도는 현저하게 증가하고 감염증의 정도가 훨씬 심하며, 임상양상도 정상인과 다른 것으로 알려져 있다. 특히 인플루엔자, 세균뇨, 악성 외이도염, 비뇌모균증, 기종성 담낭염, 기종성 신우신염 또는 방광염, 급성 신유두괴사, 신주위 농양, 진균성 요로 감염증, 그람 음성균에 의한 폐렴, 괴사성 연조직 감염과 족부 궤양 관련 감염증 등은 당뇨병과의 관련성이 이미 입증된 감염질환들이다. 당뇨병 환자에서 감염증의 발생빈도는 약 14.4%에서 39.5%까지 보고되고 있으며, 국내에서는 폐결핵 20%, 요로 감염 20%, 폐렴 16%, 진균감염 7.6%, 균혈증 6.2%, 족부 궤양 관련 감염증 5.5%의 순으로 보고되고 있다. 당뇨병환자가 감염증에 대한 원인에 대해서는 확실히 밝혀지지는 않았지만 탈수, 영양실조, 다형 백혈구의 기능 장애, 혈액 순환장애 및 신경병증 등으로 설명되고 있다. 특히 당뇨병환자에서는 미세 혈관병증과 죽상경화증이 흔히 발생하기 때문에 각 조직으로의 혈액 공급이 감소되어 각 장기 조직에서는 정상적인 영양 및 산소 공급과 적절한 면역 반응을 유지하는 것이 어려워 결과적으로 감염증에 걸리기 쉽다. 이 글에서는 여러 가지 감염증 중 족부 궤양 감염증, 기종성 신우신염, 비대뇌모균증, 간농양에 대해 사례를 중심으로 알아보겠다.

Purpose : Several methods of IV ${\gamma}-globulin$(IVG) infusion are effective in the treatment of autoimmune disease, including idiopathic thrombocytopenic purpura(ITP). But it is not known which method is more effective in the treatment of ITP. The effectiveness of these two methods of IVG infusion was studied in terms of platelet recovery rate, side effects and recurrence rate. Methods : Forty seven patients with acute ITP in the department of pediatrics, Eulji University Hospital from January 1995 to June 2001 were enrolled. We assesssed the treatment effects of 47 patients blindly selected; IV ${\gamma}-globulin$ 2 g/kg/day in one day(treatment group A, n=25), 400 mg/kg/day in five days(treatment group B, n=22). Results : Treatment group A increased platelet count more rapidly on the 2nd, 4th and 6th day of treatment than treatment group B. Side effects like fever, chill and vomiting were more frequent in treatment group A than treatment group B. The platelet count on the sixth day of treatment showed a greater increase in the cases which had side effects than in the cases which did not. There was no difference between the two groups in the recurrence rate. Conclusion : IV ${\gamma}-globulin$ 2 g/kg/day in one day increases platelet count more rapidly than 400 mg/kg/day in five days, and is favorable for the prevention of a severe hemorrhagic episode like early intracranial hemorrhage.

Infection of Epstein-Barr virus(EBV) gives rise to a broad spectrum of clinical manifestations in children. Although renal involvement is rare, diverse renal manifestations are known from hematuria to acute renal failure. Secondary membranous nephropathy(MN) associated with systemic EBV infection is an uncommon renal pathology and only two cases have been reported. We are adding another case of MN associated with EBV infection in a child. An 8-year-old girl was admitted for renal biopsy. She had been followed up for microscopic hematuria and intermittent proteinuria for 5 months. There had been no specific findings in serology and radiology. Tonsil biopsy had been done due to exudative tonsillar hypertrophy and enlarged multiple cervical lymph nodes. And it showed EBV-associated lymphoproliferative findings. Serologic tests for EBV showed positive evidence of recent infection; viral capsid antigen(VCA) IgM was borderline positive, VCA IgG and early antigen IgG were positive, and EB nuclear antigen IgG was negative. In Situ Hybridization of tonsil for EBV mRNA was positive. Because her proteinuria and hematuria were aggravated at that time(protein 3 +, RBC >60/HPF), renal biopsy was done. Renal biopsy showed the findings of MN, characterized by thickened capillary walls with epimembranous spikes on light microscopy and subepithelial, mesangial and subendothelial electron dense deposits on electron microscopy. On immunofluorescence microscopy, IgG, C1q, kappa and lambda chains were positive. After steroid administration, proteinuria and hematuria resolved gradually within 6 months.

그레이브스 갑상선기능항진증은 자가면역질환의 하나로 방사성 옥소가 간편하고 경제적이며 효과적인 치료법임이 알려져 있는데 방사성 옥소 투여 후 갑상선 조직의 자극 및 파괴에 따라 각종 항원의 노출의 증가와 이에 대한 자가항체의 변동이 예상된다. 저자들은 추정 갑상선 무게를 고려한 6-10 mCi의 방사성 옥소를 투여 받은 그레이브스 갑상선기능항진증 환자 90명을 2년간 추적하여 치료 전 후의 혈청 갑상선자극 면역글로불린(TBIIl)활성도와 thyroglobulin 및 antithyroglobulin antibody의 변화를 관찰하였다. 1) 대상환자 90명의 연령분포는 14-58세(중앙치 30)였으며 여자가 72명(80%)이었다. 2) 평가대상 환자 중 치료 전 TBIIl 활성도가 정상범위였던 경우는 15명(30%)이었고 증가된 경우는 35명(70%)이었다. 치료 전보다 치료 3개월 후에 TBII 활성도가 더 증가된 경우는 31명(62% )이었다. 3) TBII 활성도가 치료 전에 증가하였거나, 치료 전에 정상범위였다가 치료 3개월 후에 증가한 환자의 TBII 활성도의 동태는 치료 3개월 후에 가장 높았고 그 후 점차 감소하였다. 이들의 TBIIl 활성도가 15%이내로 정상화된 정도는 치료 후 6개월에 40%, 12개월에 82%였다. 4) 치료 전 antithyroglobulin antibody가 양성인 경우 80%에서 3개월 후에도 혈청 thyroglobulin의 동태는 치료 3개월 후에 높았다가 증가가 없었으며 치료 전 antithyroglobulin antibody가 음성인 경우 60%에서 치료 3개월 후에 혈청 thyroglobulin의 증가가 있었다. 5) antithyroglobulin antibody가 음성인 경우의 혈청 thyroglobulin의 동태는 치료 3개월 후에 높았다가 점차 감소하는 경향을 보였으며 antithyroglobulin antibody가 양성인 경우의 혈청 thyroglobulin의 동태는 치료 후 시간이 지남에 따라 점차 감소하였다. 6) 치료 전 antithyroglobulin antibody가 음성인 경우 치료 후 시간 경과에 따라 동시에 측정한 혈청 TBII 활성도와 thyroglobulin 사이에는 통계적으로 유의한 상관관계가 있었다(p<0.01). 한편 치료 전 antithyroglobulin antibody가 양성인 경우 치료 후 시간 경과에 따라 동시에 측정한 혈청 TBII 활성도와 thyroglobulin 사이에는 통계적으로 유의한 상관관계가 없었다(p= 0.16). 이상의 결과로 방사성 옥소를 투여 받은 그레이브스 갑상선기능항진증 환자에서 혈청 TBII 활성도는 항갑상선제를 투여 받은 경우와는 달리 초기에 증가하였다가 시간이 지남에 따라 점차 감소함을 알 수 있었으며 그 감소 정도는 항갑상선제만을 쓴 경우보다 더 빠를 것으로 생각된다. 따라서 혈청 TBII 활성도와 thyroglobulin은 방사성 옥소 치료효과의 관찰에 중요한 역할을 할 것으로 생각되며 특히 antithyroglobulin antibody가 음성인 경우 혈청 thyroglobulin은 혈청 TBII 활성도를 반영할 것으로 사료된다.

Human endogenous retroviruses (HERVs) were inserted into the human genome millions of years ago but they are currently inactive and non-infectious due to recombinations, deletions, and mutations after insertion into the host genome. Nonetheless, recent studies have shown that HERV-derived elements are actually involved in physiological phenomena and certain diseases including cancers. Among the various physiological phenomena related to HERV-derived elements, it is necessary to focus on inflammatory response. HERV-derived elements have been reported to be directly involved in various inflammatory diseases, including autoimmune diseases such as rheumatoid arthritis, multiple sclerosis, amyotrophic lateral sclerosis, and Sjogren's syndrome. As a mechanism for regulating inflammation through HERV-derived elements, the possibility that HERV-derived elements may cause nonspecific innate immune processes and that HERV-derived RNA or proteins may cause selective signaling mechanisms through specific receptors can be considered. However, the mechanism through which HERV-derived elements regulate inflammatory response, such as how silent HERV elements are activated in inflammatory response and what factors and signaling mechanisms are involved in HERV-derived elements, have not been identified to date, making it difficult to study the onset of HERV-related inflammatory disease. In this review, we introduce HERV-related autoimmune diseases and propose the mechanisms of HERV-derived elements at the molecular level of HERV in inflammatory response.
