        일차성 사구체신염의 치료

        임천규 ( Chun Gyoo Ihm ) 대한내과학회 2013 대한내과학회지 Vol.84 No.1

        Much progress has been made in the elucidation of potential pathogenetic mechanisms of glomerulonephritis such as anti-PLA2R autoantibody in membranous nephropathy and under-galactosylated IgA1 in IgA nephropathy as well as in the fields of treatment. This knowledge is, hopefully in the future, being applied in the development of the creation of rational therapeutic approaches. Current treatment strategies for glomerular diseases recommended by many clinical studies include high-dose glucocorticoids, calcineurin inhibitors, cyclophosphamide, mycophenolate mofetil, and rituximab. Although these therapies have been effective in treating immune-mediated glomerular diseases, they all have potentially serious side effects. (Korean J Med 2013;84:13-18)

        Bezafibrate is a lipid-lowering agent and one of the fibric acid derivatives. It is relatively safe and well tolerated and adverse reactions to bezafibrate have largely been restricted to gastrointestinal distrubances. But a few cases of rhabdomyolysis after bezafibrate administration have been reported and recently we experienced bezafibrate-induced rhabdomyolysis in patients with chronic renal failure. So we report this case with the bone scan finding and the literature review. We believe that this is the first case report of bezafibrate-induced rhabdomyolysis in Korea.

        디클로페낙(Diclofenac Sodium)에 의한 미세변화 신증후군

        임천규(Chun Gyoo Ihm),이태원(Tae Won Lee),김명재(Myung Jae Kim),박경분(Kyoung Bun Park),한요셉(Yo Seb Han),양문호(Moon Ho Yang) 대한신장학회 2000 Kidney Research and Clinical Practice Vol.19 No.3

        NSAIDs are now the most widely prescribed of all drugs for the therapy of a large variety of disorders including rheumatologic disorders, and so the population of patients who are at risk for adverse effects of these drugs is rapidly expanding. A number of renal and electrolyte problems have been associated with the use of NSAIDs, including alterations in glome-rular filtration rate, hyperkalemia, acute interstitial nephritis and papillary necrosis. While the use of NSAIDs has also been associated with minimal change nephrotic syndrome, this complication has almost invariably occured in association with an acute inter-stitial nephritis. Recently, we experienced a case of minimal change nephrotic syndrome without significant interstitial inflammation associated with the use of NSAIDs. This patient is a 64-year-old female who developed the generalized edema and about 10kg of weight gain since three days ago. She had taken the anti-inflammatory drugs for five years intermittently and started taking diclofenac sodium, 25mg orally three times a day, 10 days before admission for increasing pain in her knees. Laboratory findings disclosed the following values WBC 5,200/mm³with only 0.6% eosinophils, total serum protein 4.0g/dL, albumin 1.2 g/dL, BUN 17mg/dL, creatinine 0.8mg/dL, sodium 140 mmol/L, potassium 4.0mmol/L, chloride 113mmol/L, total cholesterol 338mg/dL, triglyceride 203mg/dL; 24-hour protein excretion 3.6g, creatinine clearance 52.8 mL/min ; serologic tests were unremarkable. A renal biopsy revealed no abnormality except for focal mild interstitial infiltration of chronic inflammatory cells with a few atrophic tubules on light microscopy. Im-munofluorescence studies showed diffuse trace mesan-gial deposits of IgM, and electromicroscopy revealed diffuse obliteration of the epithelial foot process and villous transformation of the epitherial cell cytoplasms without electron-dense deposits. These findings were consistent with minimal-change disease. Diclofenac was discontinued on admission because of the likeli-hood the renal disease was drug-related and she treated with low-dose(40-80mg/d) of furosemide. Four-teen days after stopping diclofenac, her massive edema and weight gain resolved and laboratory studies showed a 24-hour urine protein excretion of 80mg and serum albumin of 2.7g/dL. There has been no relapse for five months since then.

        N/A Objective: Diverse glomerular disorders leadsing to progressive glomerulosclerosis share the common features of increased mRNA expression for extra- cellular matrix protein and growth factors. The precise role of angiotensin II in contributing to these disturbances is currently unknown. ACE inhibitors have been proved to be beneficial in protecting against glomerular injury in animal models and many of human glomerular diseases. Type IV collagen is a main component of extracellular matrix in the mesangium : its increased accumulation is a common pathologic finding in the glomerulosclerosis. There are some evidences that the beneficial effect of ACE inhibitor does not solely depend on the hemodynamic effect, but may be mediated by other effect. The purpose of this study is to evaluate the effects of high glucose, angiotensin II and angiotensin converting enzyme inhibitor on the expression of PCa₁(lV) in mesansial cells(MCs). Methods: Human mesangial cells were cultured with standard method. To investigate the effect of each drug and high glucose condition, MCs were cultured in the normal-glucose medium(100mg/dl) and high-glucose medium(450mg/dl), respectively. An- giotensin II and angiotensin converting enzyme inhibitor(captopril) were added to culture medium at final concentration of 10 M which is the physiologic dose in vivo. MCs were cultured in each condition for 3days, when the maximal effect of high glucose on MCs, and harvested for mesurement of the expression of PCa₁(IV) mRNA. To quantitate the PCa(1V) mRNA levels in each condition, semiquantitatine RT-PCR was done with co-amplification of house keeping gene. Results: PCa₁(IV) mRNA expression was significantly increased in high-glucose medium(30mM) compared to normal-glucose medium(5.5mM)(2.28±0.34 vs 0.96±0.08, p<0.05). Administration of angiotensin ll(10(-6)M) in culture media induced a further increment in the PC a >(IV) mRNA expression to 4.64±0.28(p<0.05). Angiotensin II in the normal-glucose medium increased the PCa₁(lV) mHNA expression as 2.69±0.23 control(p<0.05). Addition of angiotensin converting enzyme inhibitor(Capopril, 10(-6)M) in high- glucose culture medium significantly suppressed the PCar(IV) mRNA expression as 0.690.11(p<0.05). Conclusion: High glucose concentration in culture medium significantly increases the mRNA expression of procollagen alphal(IV) than normal glucose concentration. Angiotensin II increases the collagen mRNA expression directly and this effect was significantly prevented by ACE inhibitor. This result suggests that hyperglycemia in diabetic millieu can directly increase collagen production, and ACE inhibitor may inhibit progressive glomerulosclerosis by decreasing collagen production as well as reducing intraglomerular pressure.

        IgA 신증 40여 년

        임천규 ( Chun Gyoo Ihm ) 대한내과학회 2009 대한내과학회지 Vol.77 No.4

        IgA nephropathy is characterized by the predominant deposition of IgA in a granular fashion diffusely in the mesangial zones of glomeruli. IgA nephropathy was first described over four decades ago and is now the most common form of primary glomerular disease. Much progress has been made in the elucidation of potential pathogenetic mechanisms such as undergalactosylated IgA1 as well as in the fields of clinical features, prognosis, and treatment. This knowledge is being applied in the development of new diagnostic methods and hopefully in the future the creation of novel and rational therapeutic approaches. (Korean J Med 77:435-443, 2009)

        N/A A multicenter prospective study was done in four-university hospital to evaluate the efficacy and safety of cyclosporin A(CyA, Cipol-N) in 64 patients with adult nephrotic syndrome mean age 34.8 years, male:female 2.4:1, duration of disease 38.0±40.9months, 31 patients with MCD, 33 patients with Non-MCD(8 FSGS, 14 MGN, 7 MPGN, 2 lupus nephritis, 1 HBsAg associated GN)]. The prior steroid responses of these patients were 17 steroid dependent, 9 frequent relapser, 4 steroid resistant and 1 other in MCD patients, and 5 steroid dependent, 5 frequent relapser, 22 steroid resistant and 1 other in Non-MCD patients. After a 2-week steroid(predni-solon 10mg/day or deflazacort 12mg/day) run-in period, CyA 5mg/kg/day and prednisolone 10mg/day (or deflazacort 12mg/day) were administered for up to 16 weeks. Of the 64 patients enrolled, ll patients were dropped out prematurely due to adverse events or protocol violation. Of the 53 patients who completed the study, 27 had MCD and 26 had Non- MCD. High response(CR and PR) rate of 68%(36/53) were obtained with CyA treatment in all patients. Although the response rate in MCD was significantly higher than that in Non-MCD(89 vs. 46%, p<0.05) and response rates were significantly different according to the previous steroid responses by univariate analysis, only previous steroid responses affected the response to CyA significantly by Logistic multiple regression analysis(p=0.03, RR 7.08); responses were 84%(27/32) in steroid dependent and frequent relapser patients, and 37%(7/19) in steroid resistant patients. 24-hr proteinuria significantly decreased after 2 weeks and serum albumin and cholesteroi increased significantly after 4 weeks of treatment compared to baseline level. The serum creatinine level was not changed during the study. No serious and unexpected side event was observed. In conclusion, cyclosporine therapy is a safe and effective mode of treatment in patients with ne-phrotic syndrome, especially in those who need pro- longed administration of steroids with resulting in unavoidable steroid complications such as frequent relapser and steroid dependent type. The patients with steroid resistant type and contraidications of steroid administration such as DM, aseptic bone neerosis etc. can also be candidates for this treatment.
