  • Objectives : The current treatment regimens for patients with nephrotic syndrome due to membranous nephropathy(MN) are based on steroids or immunosuppressive therapy with the aim of reducing proteinuria and improving outcome. Although these treatments attenuate the deterioration of renal function in MN patients, it has been suggested that all are burdened by significant toxicity. Therefore, more specific and less toxic therapies are needed. This study was to evaluate the effects of Coptidis Rhizoma Extract(CRE) on the MN induced by cBSA in mice. Methods : Mice were divided into 4 groups. One group named for 'Normal' was injected with a saline solution not to be immunized. The rest groups were treated as follows; After mice were immunized with 0.2 mg of cBSA and Freund's complete adjuvant one time every two weeks for 6 weeks, they received intra-peritoneal injection of 10 mg/kg of cBSA daily for 4 weeks. Also, they were divided into 3 groups. The first named for 'Control' was not given CRE. The second for 'CRE-250' was given oral administration of 250 mg/kg of CRE daily for 4 weeks. The third for 'CRE-500' was given 500 mg/kg of CRE. All of mice were sacrificed 4 weeks after the first immunization. We measured a body weight and 24hrs proteinuria as well as serological analysis. The morphologic changes of renal glomeruli were also observed with a light microscope and an electron microscope. Results : The levels of 24 hrs proteinuria, triglyceride, IgG, IL-6 were significantly decreased in both CRE groups. And the level of IgM was significantly decreased in CRE-250 group. In histological findings of kidney tissue, thickening of GBM and deposition of electron-density were consideraly decreased in both CRE groups. Conclusions : The present study suggests that CRE is highly effective when treating mice with MN induced by cBSA. More clinical data and studies are to be done for efficient application.

  • Purpose: Hepatitis B virus (HBV) infection is among etiologies of secondary membranous nephropathy (MN) in pediatric patients. We evaluated expression of phospholipase A2 receptor (PLA2R), a specific target antigen of primary MN, in pediatric HBV-related MN. Methods: We retrospectively reviewed patients with biopsy-proven HBV-related MN from the renal biopsy registry and electronic medical records of Severance Hospital, Seoul, Korea, from 1993 to 2004. Paraffin-embedded human kidney tissues were retrieved and immunohistochemically stained for PLA2R. Results: Ten pediatric patients with 13 biopsied specimens were reviewed. The predominant pathological stage was stage II-III, and second was stage II. The intensity of staining for IgG was greatest, with less intense staining for IgM, IgA, C3, C4, and C1q. All the patients had angiotensin-converting enzyme inhibitor combined with glucocorticoid, and four patients converted to cyclosporine treatment from glucocorticoid monotherapy. Urinalysis of all the patients normalized after variable period. PLA2R staining was demonstrated in the outer glomerulus in 3 out of 13 biopsies, 2 of which were obtained from the same patient over a 5-year interval. Conclusions: PLA2R was expressed in a small number of cases diagnosed as pediatric HBV-related MN, indicating that some HBV-related MN cases may be primary MN concurrent with HBV infection.

  • Objective: The purpose of experimental study was to prove the effects of Boyangmakseong-bang (BYMSB) treatment on cBSA-induced in a MN mouse model. Methods: We divided mice into 4 groups. The Normal group had no treatment. We used cBSA and induced MN mouse model to the other 3 groups. The Control group was treated with cBSA (9mg/kg i.p) only. The second group, named 'BY-250', was treated with cBSA (9mg/kg i.p) and BYMSB extract (250mg/kg, p.o). The third group, named 'BY-500', was treated with cBSA (9mg/kg i.p) and BYMSB extract (500mg/kg, p.o). After cBSA and BYMSB extract treatment for 4 weeks, the increase in percentage of body weight, proteinuria, serum albumin, total cholesterol, creatinine and BUN of all groups were measured. The CD3+, CD19+, CD4+, CD8+ cell levels of spleen of all groups were analyzed. IgA, IgG, IgM, IL-$1{\beta}$, TNF-${\alpha}$, IL-6 and IFN-${\gamma}$ levels of all groups were gauged. H&E staining, immunofluorescence staining and electron microscopy of kidney were observed. Results: BYMSB showed significant decrease in the 24hrs proteinuria, serum total cholesterol, serum IgG levels and BUN levels, and showed significant increase in the serum albumin levels compared with the control group. BYMSB showed increase in the increasing percentage of body weight and IFN-${\gamma}$ levels compared with the control. BYMSB showed decrease in the CD3+ T cells, CD4+ Th cells, IL-$1{\beta}$, TNF-${\alpha}$ and IL-6 levels, but did not show significant change compared with the control. BYMSB showed considerable decrease in the thickening of the GBM on H&E staining, deposition of IgG on immunofluorescence staining and deposition of electron-density on electron microscopy of kidney compared with the control. Conclusions: According to the above results, it is suggested that BYMSB decreases the symptoms of MN induced by cBSA in a mouse model. Therefore BYMSB seems to be applicable to MN in clinical practice.

  • 목적 : 막성 신병증은 소아에서 드문 신질환이다. 저자들은 일차성 막성 신병증의 임상 경과의 이해와 치료 방침의 결정에 도움을 주고자 일차성 환자들을 후향적으로 고찰하였다. 방법 : 1977년부터 2003년에 소아 막성 신병증 환자 58명 중 42명(72.4%)이 B형 간염 연관성이었고, 16명(27.6%)이 일차성이었다. 2000년 이후 진단된 환자는 모두 일차성이었다. 임상-병리학적 소견(성별, 연령, 단백뇨, 혈청 알부민, 콜레스테롤, 크레아티닌 청소율, 신세뇨관-간질 변화, 신사구체 경화증, 고혈압, 신정맥혈전증, ACE inhibitor 및 면역억제제 사용력)을 조사하였고, 관해군과 비관해군 간 비교를 하였다. 결과 : 남자 6명, 여자가 10명이었고, 진단 시 중앙 연령은 13세 5개월이었다. 발현 증상은 신증후군(7명, 43.8%), 육안적 혈뇨(5명, 31.3%)와 현미경적 혈뇨 및 단백뇨(3명, 18.8%)였다. 고혈압(2명, 12.5%), 신정맥 혈전증(2명, 12.5%)과 저칼슘성 테타니(1명)가 동반되었다. 조직소견 상범사구체성(6명, 37.5%) 또는 분절성 경화증(5명, 31.3%), 반월체(1명)와 경도(11명, 68.7%) 또는 중등도의 신세뇨관-간질 변화(3명, 18.8%)가 보였다. 13명(86.7%)이 스테로이드를 투여 받았고, 이 중 2명은 cyclophosphamide, 1명은 cyclosporin을 투여 받았다 10명(52.5%)은 ACE inhibitor를 투여받았다. 진단 1개월 후 누락된 1명을 제외하고, 7명(46.7%)에서 단백뇨가 소실되었고, 8명(53.3%)은 단백뇨가 지속되었으며, 그 중 2명(13.3%)은 만성신부전으로 진행하였다. 관해군과 비관해군간에 임상-조직 병리학적 소견은 유의한 차이가 없었다. 결론 : 우리나라 소아에서 막성 신병증은 일차성이 막성 신병증의 대부분을 차지하게 되었는데, 그 이유는 B형 간염 예방 접종 도입 이후 B형 간염 연관성 막성 신병증이 현저하게 감소하였기 때문이다. 이 질환의 임상 경과의 이해와 치료 방침의 확립을 위해서 다기관의 전향적 연구가 필요하다.

  • 목적 : 경피적 신생검에 의해 사구체신염으로 진단된 환자들을 대상으로, 병리조직학적인 분류에 근거하여 사구체신염의 종류와 발생 빈도를 조사하였다. 또한 각 사구체 질환별로 발현된 임상 양상의 형태와 임상 양상의 형태에 따른 사구체신염의 종류와 발생 빈도를 분석하였다. 방법 : 1986년 1월부터 1996년 12월 사이에 인제의대 부산백병원 소아과에 입원하여 신질환이 의심되어 초음파 유도하에 Tru-cut needle을 이용하여 경피적 신생검을 시행한 환자 중 사구체신염으로 진단된 15세 이하의 환자 310례를 대상으로 하였다. 환아들의 임상 양상은 의무기록을 중심으로 후향적으로 분석하였다. 결과 : 1) 대상 환자는 310명 이었고, 나이는 13개월부터 15세사이 였으며, 남녀의 비는 남자 188명, 여자 122명으로 1.54:1 남자에서 발생빈도가 높았다. 2) 전체 사구체신염 환자중 원발성 사구체신염은 217명. 속발성 사구체신염은 93명으로, 원발성 사구체신염이 더 많았으며 2.33 : 1의 비율을 보였다. 이를 빈도순으로 살펴보면 미세변화 신증이 32.6%로 가장 많았으며, 다음으로는 IgA신증 15.8%, 알레르기 자반증성 신염 13.5%, 연쇄상구균 감염후 사구체신염 8.1%의 순이었다. 3)내원 당시에 발현되었던 임상 양상의 형태를 기준으로 하여 5가지의 임상 증후군으로 분류하였을 때, 무증상성 요이상을 동반한 사구체신염이 134례로 43.2%로 가장 많았으며, 신증후군이 127례로 41.0%, 급성 사구체신염이 44례로 14.2%, 만성 사구체신염이 3례로 1.0%, 급속진행성 사구체신염이 2례로 0.6%를 차지하였다. 4) 원발성 사구체신염의 분포를 보면 미세변화 신증이 46.5%로 가장 많았으며, 다음으로 IgA신증 22.6%, Thin GBM disease 7.8%, 막증식성 사구체신염 5.5%, 메산지움 증식성 사구체신염과 국소성 분절성 사구체경화증이 각각 4.6%, 막성 신병증 0.9%, 경화성 사구체신염 0.9%. 반월형 사구체신염 0.5%의 순이었고 기타 어느곳에도 분류하지 못하는 경우가 6.0%를 차지하였다. 5) 속발성 사구체신염의 원인 질환으로는 알레르기 자반증성 신염이 45.2%로 가장 많았으며, 연쇄상구균 감염 후 사구체신염이 26.9%, B형 간염 바이러스와 연관된 사구체신염이 17.2%, 낭창성 신염이 6.5% 그리고 기타질환이 4.2%를 차지하였다. 기타 질환에는 Alport증후군 2례, 용혈성 요독 증후군 1례, Fibrillary 신염 1례 였다. 결 론 : 신생검을 시행하는 기관에 따라 신생검의 적응증이 다르며, 병리조직학적 분류 또한 일치되지 않은 실정이다. 그러므로 각 기관의 특성에 따라 어떤 특정한 질환의 환자가 상대적으로 많을 가능성이 있으므로 국내에서의 소아 신질환의 발병형태를 보다 체계적으로 조사하고 이를 자료화하기 위해서는 개별 기관들의 연구결과만으로는 미흡하다고 생각되며, 이를 위해서는 전국적인 협동조사가 필요하다고 사료된다.
