Objective: Recently scolopendrid aquacupuncture has been a good effect on pain control but it has not been known about clinical safety. So, In order to prove the clinical safety of scolopendrid aquacupuncture, We have observed the physical reac-tion and clinical pathology test after scolopendrid aquacupuncture treatment. Methods: We analyzed physical reaction and clinical pathology test before and after Scolopendrid aquacupuncture treatment of 30 patients suffering from pain, who admitted department of Acupunture and Moxibustion, College of Oriental Medicine, Won-Kwang University Kwangju hospital. Results & Conclusions: The results were summarized as follows. 1) The distribution of sex was 14 males and 16 females, and the average of patients age was 46.2 years. 2) The distribution of symptom was lumbago, lumbago with radiating pain, nuchal pain and knee joint pain. 3) In the 30 patients treated with Scolopendrid aquacupuncture, hematologic test did not show remarkable change. 4) In the 30 patients treated with Scolopendrid aquacupuncture, Liver function test(AST, ALT, ALP) showed a slight decrease on the contrary, and abnormal rate showed a decrease of 1.0%(from 3.3% to 2.3%) compared with previous study. 5) In the 30 patients treated with Scolopendrid aquacupuncture, Renal function test(BUN, Cr) and abnormal rate(from 2.5% to 2.0%) showed a slight decrease on the contrary. 6) In the 30 patients treated with Scolopendrid aquacupuncture. Electrolyte were normal range before & after treatment. 7) In the results of the Urine analysis of 30 patients, Leukocyte, Protein. Glucose, Keton, Bilirubin, U-bilinogen were not detected before and after Scolopendrid aquacupuncture treatment, and the rest almost made no difference. 8) In the Physical reactions, all of the patients complained of pain of body partially, only one patient showed reddish and itch, but symptoms like those were entirely disappeared within 24 hours and whole body pain, swelling, headache, dizziness, fatigue and nausea was not observed.

Purpose : Long-term use of Cyclosporine(CsA) reduce renal blood flow by afferent arteriolar vasoconstriction and lead to chronic pathologic changes of CsA nephrotoxicity - 1) interstitial nephritis(IN); tubular atrophy (TA) and/or interstitial fibrosis(IF),2) arteriolopathy(AP). The Object of this study is to estimate the incidence of chronic pathologic CsA nephrotoxicity by duration of treatment and type of renal disease, relationship between histologic and clinical nephrotoxicity, and optimal duration of CsA therapy. Methods : 102 children with steroid resistant or dependent nephrotic syndrome confirmed by renal biopsy and treated with CsA from 1986 to 1997 were enrolled in this study(58 MCNS, 10 FSGS, 10 MGN, 15 $Henoch-Sch\"{o}nlein$ purpura nephritis with nephrotic syndrome (HSPN) and 9 IgA nephropathy with nephrotic syndrome(IgAN)). CsA was administered for 1yr, 1.5yr, 2yr in 24, 12, 22 MCNS patients and 2, 2, 6 FSGS patients respectively, 1yr, 2yr in MGN and 1yr in HSPN and IgAN. Sequential biopsies were done in all 102 patients after CsA treatment for evaluation of pathologic nephrotoxicity. Results : Complete remission rate was 92.2% (100% in MCNS and MGN, 80% in FSGS, 86.6% in HSPN and 55.5% in IgAN). Incidence of relapse during 6months after CsA treatment was significantly decreased compaed with relapsing spisodes during 6months before CsA treatment in MCNS(P<0.0001) and FSGS(P<0.0001). According to pathologic changes, 71 patients(69.6%) showed no pathological change, 24 patients(23.5%) showed IN and 7 patients(6.8%) showed AP. IN was 16.6%, 33.3%, 27.2% in 1, 1.5, 2 year of CsA treatment group in MCNS. AP was 0%, 16.6%, 9% in 1, 1.5, 2 year of CsA treatment group in MCNS. 14 out of 58 MCNS(24.1%) showed IN and 4 out of 58 MCNS(6.8%) showed AP. Incidence of pathologic change was significantly lower in CsA therapy of <1yr than >1yr(P=0.03). There were no significant difference of incidence of pathologic change in original renal disease, age and sex. Conclusion : Duration of CsA treatment was significant risk factor for nephrotoxicity and optimal duration seemed to be 1 year. Pathologic change due to nephrotoxicity did not correlate with deterioration of renal function and only detectable by renal biopsy.

Purpose: This retrospective study of 126 children with symptomless primary hematuria was undertaken to determine the distribution of various histologic types by renal biopsy, clinical outcome according to the biopsy findings and also to find out feasibility of performing renal biopsy in these children. Patients and Methods : Study population consisted of 126 children with symptom-less primary hematuria who have been admitted to the pediatric department of Kyung-poot National University Hospital for the past 11 years from 1987 to 1998 and renal biopsy was performed percutaneously. Hematuric children with duration of less than 6 months, evidences of systemic illness such as SLE or Henoch-Schonlein purpura, urinary tract infection, and idiopathic hypercalciuria were excluded from the study. Results : Mean age of presentation was 9.2${\pm}$3.3 years (range ; 1.5-15.3 years) and male preponderance was noted with male to female ratio of 2:1. IgA nephropathy was the most common biopsy finding occuring in 60 children ($47.6\%$), followed by MsPGN in 13 ($10.3\%$), MPGN in 5 ($3.9\%$), TGBM in 6 ($4.7\%$), Alport syndrome in 2 ($1.6\%$), FSGS in 1 ($0.8\%$), and in 39 children ($30.9\%$), 'normal' glomeruli were noted. Recurrent gross hematuria was more common than persistent microscopic hematuria (84 versus 42), and especially in IgA nephropathy, recurrent gross hematuria was the most prevalent pattern of hematuria. In 58 out of 126 cases ($46.0\%$), hematuria was isolated without accompa-nying proteinuria and this was especially true In cases of MsPGN and 'normal' glomer-uli by biopsy finding. Normalization of urinalysis (disappearance of hematuria) in IgA nephropathy, MsPGN and 'normal' glomuli group were similar and it was $14\%,\;27\%\;and\;21\%$ respectively during 1-2 years of follow-up period, and $37.1\%,\;40\%\;and\;35\%$ respectively during 3-4 years of follow-up periods. However, abnormal urinalysis persi-sted in the majority of children with MPGN, TGBM. Alport syndrome and FSGS. Renal function deteriorated progressively in 6 cases (3 with IgA nephropathy, 2 with Alport syndrome and 1 with TGBM). Conclusion : In summary, present study demonstrates that in 126 children with symptomless primary hematuria, IgA nephropathy was the most common biopsy findings followed by MsPGN, MPGN, TGBM, Alport syndrome and FSGS, and 'normal glomeruli' was also seen in 39 cases ($30.9\%$). Renal histology could not be predictable on the clinical findings, so that to establish appropriate long-term planning for these children, we would recommend to obtain precise histologic diagnosis by renal biopsy.

Purpose : One of the most important adverse effects of long-term cyclosporine therapy is nephrotoxicity, the morphologic changes of which include interstitial fibrosis and arteriolar hyalinization. Recently, several authors have shown that osteopontin plays an important role in the development of interstitial fibrosis by acting as a macrophage chemoattractant and stimulating the production of $TGF-{\beta}$ in experimental cyclosporine nephrotoxicity. However, the relationship between osteopontin and $TGF-{\beta}$ in humans has not been clearly documented so far. We studied the expression of osteopontin and $TGF-{\beta}$ in children with minimal change nephrotic syndrome treated with cyclosporine to demonstrate whether there is a relationship between cyclosporine toxicity and osteopontin expression as previously shown in animal models. Materials and methods : Nineteen children (15 males and 4 females) were the subject of this study. Renal biopsies had been performed before and after the cyclosporine therapy (mean duration: 15.9 months). In 5 patients, additional biopsies were performed after completing the cyclosporine treatment (mean; 26 months). The expressions of osteopontin and $TGF-{\beta}$ were evaluated by immunohistochemistry in the glomeruli and tubulointerstitium. Results : Osteopontin expression was significantly increased in the glomerular mesangium and tubules after cyclosporine treatment. But there was no statistically significant increase of $TGF-{\beta}$ in the interstitium. There was no significant increase in tubular osteopontin and interstitial $TGF-{\beta}$ expression in those cases developing interstitial fibrosis after cyclosporine treatment compared with cases those not developing interstitial fibrosis. No significant changes in osteopontin or $TGF-{\beta}$ expression were observed in subsequent 5 biopsy samples after discontinuation of cyclosporine compared with the first follow up biopsies. Conclusion : These results suggest that osteopontin is a nonspecific marker of renal injury rather than a mediator of interstitial fibrosis in cyclosporine nephrotoxicity of human.

Purpose : We know little about the natural course of IgA nephropathy (IgAN) in association with histologic changes especially in children. We investigated clinicopathologic features with long-term follow-up biopsy to clarify the outcomes and prognostic indicators for childhood IgAN. Methods : From our patients' medical records, we retrieved 20 patients with IgAN, to whom renal biopsies had been performed for the initial diagnosis and follow-up to find out any histologic changes. Initial and follow-up biopsies were classified by Haas classification. The changes of these parameters were compared with the evolution of clinical features. Results : Patients were treated with angiotensin-converting enzyme inhibitors in combination with angiotensin receptor blockers (in subclass II or above) and short-term cyclosporine A(in patients showing nephrotic syndrome). Histologic improvement in 7 cases and deterioration in 3 cases were observed. At the time of last biopsy, 10 cases (50%) showed clinical remission and the others showed improved clinical features. These clinical outcomes did not correlate with initial Haas classifications. Hypertension at onset observed in 5 cases (25%) revealed significant correlation with clinical outcome (P =0.01) and last Haas classification (P =0.007). None of the cases showed progression to CRF or ESRD. Conclusion : During a mean follow-up of $10.8{\pm}3.4$ years, childhood IgAN showed good clinicopathologic outcome. Hypertension at onset was only a strong predictor of clinicopathologic outcomes, but initial Haas classification cannot predict outcomes in children. Histologic change of IgAN in long term follow-up period cannot be completely predicted by clinical data and vice versa. Therefore, a renal biopsy should be considered as a part of follow-up plan.

Purpose: Rapidly progressive glomerulonephritis (RPGN) is characterized by the rapid increase in serum creatitnin and crescents formation involving more than $50\%$ of glomeruli. 10 patients who had been treated for RPGN were studied retrospectively for thier underlying diseases and clinical features Method: Cilinical review was performed on 10 children who were diagnosed with RPGN by clinical features and renal biopsy and followed up at department of pediatrics during tile last 10 years, from May 1990 to May 2000. Result: There were 6 males and 4 females between the ages of 2.1 and 14.3 years (mean $10.9{\pm}3.8$). 3 had Henoch-$Sch{\ddot{o}}nlein$ purpura nephritis; 2, idiopathic rapidly progressive glomerulonephritis; 2, lupus nephritis; 1, hemolytic uremic syndrome; 1, membranous glomerulonephritis and 1, microscopic polyangiitis. The most common chief complaints were gross hematuria and oliguria. Initial clinical features included proteinuria, edema, hypertension, nausea and arthralgia. Mean serum BUN was $74.2{\pm}39.1\;mg/dL$ mean serum creatinin, $3.2{\pm}1.8\;mg/dL$ and mean creatinin clearance, $26.5{\pm}13.2\;mL/min/1.73m^2$. Antineutrophil cytoplasmic antibody was positive only in microscopic polyangiitis. ANA and Anti-DNA antibody were positive in two lupus nephritis patients. Serum complements were decreased in 4 patients. All patients except Hemolytic uremic syndrome received steroid pulse therapy and immunosupressive agents. 3 patients were performed acute peritoneal dialysis and 2 patients were given plasmapheresis. At the last follow up, 1 patient was dead, 4 patients had elevated serum creatinin, 2 of these 4 patients were on chronic ambulatory peritoneal dialysis and 6 patients had normal renal function. Conclusion: Rapidly progressive glomerulonephritis is a medical emergency that requires very rapid diagnosis, classification, and therapy. Appropriate therapy selected on the basis of underlying disease mechanism can substantially improve renal survival. (J. Korean Soc Pediatr Nephrol 2001 ; 5 : 78-86)

Purpose : This study was performed to report the diagnosis and treatment of nephrotic syndrome manifesting in the first year of life. Methods : We retrospectively reviewed the clinical data with chart review in 7 patients who were diagnosed as nephrotic syndrome manifesting in the first year of life from 1996 to 2007. Results : Three patients had congenital nephrotic syndrome, the other 4 patients had infantile nephrotic syndrome. Their ages ranged from birth to 11 months and male to female ratio was 1 to 6. Renal biopsies were done in 6 patients. One patient had Finnish type congenital nephrotic syndrome, 2 patients had diffuse mesangial sclerosis, 2 patients had focal segmental glomerulosclerosis and 1 patient had minimal change disease. Genetic analyses of NPHS2, PLCE1, and WT1 were done in 4 patients and 2 of them had WT1 mutation. Among 3 patients with congenital nephrotic syndrome, 1 patient was diagnosed as congenital nephrotic syndrome of Finnish type and the other 2 patients were diagnosed as Denys-Drash syndrome. All of the patients with congenital nephrotic syndrome died due to sepsis. Among 4 patients with infantile nephrotic syndrome, 2 patients died and 1 had remission, another patient progressed to end stage renal disease. Conclusion : Most of nephrotic syndrome manifesting in the first year was hereditary renal disease. Patients with nephrotic syndrome manifesting in the 3 month of life had poorer prognosis and needed more aggressive management including early dialysis and renal transplantation might be considered compared with infantile nephrotic syndrome. Further genotype-phenotype correlation studies are needed.

Purpose : Henoch-$Sch{\ddot{o}}nlein$ purpura nephritis(HSPN) accompanied by nephrotic syndrome(NS) is known to have a poor prognosis and effective treatment is still controversial, even though both corticosteroids and immunosuppresant have been used for therapy. Cyclosporine A(CsA) is a well known immunosuppresant and widely used in renal transplantation and glomerular diseases especially steroid resistant. The aims of this study was to evaluate the therapeutic effect of CsA and to compare CsA with previously reported our data of rifampin(RFP) and azathioprine(AZA) in children with HSPN accompanied by NS. Methods : 37 HSPN patients with NS confirmed by renal biopsy were selected. Of these, 17 patients were treated with CsA(5 mg/kg/day) fur 6-8 months, 7 children were treated with RFP(10-20 mg/kg/day) for 9-12 months and 13 patients were treated with AZA(2 mg/kg/day) fur 8 months. Along with these regimens, low dose oral prednisolone(0.5-1 mg/kg, qod) was also used. Sequential renal biopsy was done in all patients 1 month after termination of treatment. Results : Complete remission rate of nephrotic syndrome was $58.8\%$ in CsA, $57.1\%$ in RFP and $38.4\%$ in AZA group after 17, 22, 11 months of mean follow-up period. Overall remission rate including partial remission was $88.2\%$ in CsA, $85.7\%$ in RFP and $84.6\%$ in AZA group. Disappearance rate of hematuria was $58.8\%$ in CsA, $57.1\%$ in RFP and $46.2\%$ in AZA group. Improvement of grade of clinical status was observed in 17 out of 17 CsA, 7 out of 7 RFP and 10 out of 13 AZA group. Improvement of pathologic class on sequencial renal biopsy was shown in 5 CsA($29.4\%$), none RFP($0\%$) and 2 AZA group($12.4\%$). Improvement on histologic immune-deposition was seen in 15 CsA($88.2\%$), 6 RFP($85.9\%$) and 4 AZA group($30.8\%$). Conclusion : In conclusion, Both CsA and RFP treated groups showed better result in complete remission rate of nephrotic syndrome and significant improvement of histologic immune-deposition compared with AZA treated group(p=0.004). So, we recommend CsA and REP rather than AZA for immunosuppresant treatment in HSPN with nephrotic syndrome.

Purpose : This study was performed to determine the natural history of histologically confirmed IgA nephropathy in pediatric patients who presented with hematuria and proteinuria. Patients and Methods : We reviewed the clinical course of 57 patients diagnosed with IgA nephropathy at the age of 15 years or younger from 1981 to 2000. All patients presented with hematuria or minimal proteinuria($<40\;mg/m^2/day$) and had normal renal function and blood pressure at the time of renal biopsy. Based on the clinical and pathological findings at the time of diagnosis, we sought for complications of IgA nephropathy such as heavy proteinuria(${\ge}40\;mg/m^2/day$), hypertension, and chronic renal failure. Results : The mean age at presentation was $9.5{\pm}2.8$ years(4 to 15 years) and 42(74%) were male. Isolated gross hematuria was observed in 20 patients(35%), microscopic hematuria in 3(5%), minimal proteinuria in 4(7%), both gross hematuria and minimal proteinuria in 15(26%), and both microscopic hematuria and minimal proteinuria in 15(26%). During a median follow-up of $7.0{\pm}3.5$ years, 38(67%) had complete resolution of hematuria and proteinuria, 12(21%) had persistently abnormal urinalysis without development of adverse events. Only 7(12%) developed adverse events : 4(7%) developed severe proteinuria, 1(2%) became hypertensive, and 2(3%) developed Impaired renal function. By univariate analysis using the chisquare test, the age at presentation(>10 years)(P<0.01) and poor histological classes of the Lee or Haas classification at onset(P<0.05) were significantly correlated with adverse events, whereas sex and clinical signs at onset were less concordant. Conclusion : We can conclude that the prognosis of IgA nephropathy diagnosed in early childhood is better and a good correlation exists between the clinical manifestations of this disease and the histological classes.

Purpose : Idiopathic Membranous Nephropathy(IMN) is a rare renal disease in children. To help better understanding of its clinical course and treatment strategies, we reviewed the clinical manifestations and pathological findings of children with IMN. Methods : Among 58 cases with MN, from 1977 to 2003, 42(72.4%) were hepatitis B virus (HBV) associated and 16(27.6%), 6 males and 10 females, were idiopathic. All cases diagnosed aster 2000 were IMN. Several clinicopathological findings(sex, onset age, proteinuria, serum albumin, cholesterol, creatinine clearance, tubulointerstitial changes, glomerular sclerosis, hypertension, renal vein thrombosis, the use of ACE inhibitor, and immunosuppressive therapy) were compared between the remission and the non-remission group of the patients with IMN. Results : The median onset age was 13.4 years. Clinical manifestations were nephrotic syn-drome(7 cases, 43.8%), gross hematuria(5 cases, 31.3%) and microscopic hematuria with proteinuria(3 cases, 18.8%). Hypertension, hypocalcemic tetany and renal vein thrombosis were accompanied in 2, 1 and 2 cases, respectively. In addition to the typical findings of MN, the kidney biopsies showed segmental sclerosis(5 cases, 31.3%) or global sclerosis(6 cases, 37.5 %), diffuse crescents(1 case), and mild(11 cases, 68.7%) or moderate tubulointerstitial changes(3 cases, 18.8%). Thirteen cases(86.7%) received oral steroid. Among them 2 cases received cyclophophamide and 1 received cyclosporin as well. Ten cases(62.5%) received ACE inhibitors. In the patients followed up, 7 cases(46.7%) became free from proteinuria (remission group) while 8(53.3%) presented continous proteinuria (non-remission group), two (13.3%) of which progressed to renal failure. Clinicopathological findings showed no significant differences between the two groups. Conclusion : With HBV vaccination, HBV associated MN decreased markedly and IMN has taken up most of MN in children. For better understanding of this rare disease, a prospective multicenter study of the clinical course and treatment strategies should be done.
