당뇨병은 전 세계적으로 급격하게 증가하면서 심각한 대혈관 및 미세 혈관 합병증들의 원인이 되고 있으며 대다수 선진국에서 당뇨병은 만성 신질환 및 말기 신부전의 가장 중요한 원인으로 알려져 있다. 당뇨병성 신증은 단백뇨를 특징으로 하며 30% 정도의 환자에서는 혈뇨도 관찰된다. 그래서 당뇨병성 신증의 발병 검진은 미세알부민뇨 검사로 하는 것이 가장 이상적이며 제 1형 당뇨병환자는 일반적으로 당뇨병 발병 5년 이후에 하며 위험인자가 있는 환자는 더 조기에 한다. 제 2형 당뇨병환자는 당뇨병 진단 시점부터 매년 하는 것을 원칙으로 한다.

Purpose: Growth failure is a common problem in chronic renal failure(CRF). We studied the effect of growth hormone(GH) treatment and the factors influencing growth on chronic peritoneal dialysis patients. Methods: Seventeen patients who were treated with peritoneal dialysis and GH for more than one year were enrolled. Factors influencing growth such as age, height at start of GH treatment, total Kt/Vurea, residual renal Kt/Vurea, hemoglobin, albumin, BUN, creatinine, total $CO_2$, calcium, phosphate and iPTH during GH treatment were compared between the growth group (increase in height-standard deviation score(Ht-SDS) after one year of GH treatment, n=l1) and poor growth group(no increase in Ht-SDS after one year of GH treatment, n=6). Results: The mean age at the start of dialysis was 7.7${\pm}$5.2 years and the mean age at the start of GH treatment was 8.5${\pm}$4.8 years. In the growth group, Ht-SDS at start of GH treatment was smaller(-1.72${\pm}$1.00 vs. -0.77${\pm}$0.88, P=0.048) and residual renal Kt/Vurea was better (1.54${\pm}$0.51 vs. 0.15${\pm}$0.26, P=0.02) than the poor growth group. After three years of GH treatment, Ht-SDS of the growth group was better than the poor growth group. Conclusion: GH treatment in children with peritoneal dialysis was more effective on patients who had more severe growth retardation. The reservation of residual renal function was important for improvement of effect of GH treatment. And the growth response during the first year of GH treatment may be predicted as the indicator for long-term response.

배경: 말기 신부전 환자에서 심장병, 특히 관상 동맥 질환의 이환이 늘어나면서 관상동맥 우회수술의 대상 환자가 지속적으로 증가하고 있다. 이들 환자군은 수술후 유병률과 사망률이 매우 높고 고위험군으로 알려져 있다. 대상 및 방법: 1996년 3월부터 2000년 5우러까지 서울 중앙 병원 흉부외과에서 술전 말기 신부전증으로 진단 받은 후 관상 동맥 우회수술을 시행받은 환자 25명을 대상으로 의무 기록을 중심의 후향적 분석을 하였다. 술전 위험 인자 및 술전 신기능, 수술 결과, 술후 경과, 수술후 합병증, 사망률 및 생존률 등을 분석하였다. 결과: 술전 평균 크레아티닌 청소율은 12.7$\pm$5ml/mim였고 술전 평균 혈중 크레아티닌 치는 6.2$\pm$3mg/dl(1.7-14.4)였다. 술전 투석을 시행중인 환자는 11례(44%)였고 술전 투석을 시행하지 않았던 14례(56%)중 8례(8/14, 57.1%)는 수술전후로 새로이 투석이 필요하였다. 술전 혈액 투석 중이었던 9례중 2례에서 수술후 복막 투석으로 전환하였다. 수술 사망률은 2례(8%)로 흡인성 폐렴과 종격동염으로 1례, 그리고 수술후 출형과 종격도염으로 1례가 사망하였다. 수술후 합병증은 14명(56%)의 환자에서 발생하여 매우 높은 발생율을 보였다. 만기사항은 2례(8%)에서 발생하였으며 사망원인은 카테터에 의한 복막염이었다. 생존 환자의 4년 생존률은 82$\pm$13% 였다. 결론: 말기 신부전 환자에서의 관상동맥 우회수술을 비교적 만족스러운 범위의 수술 사망률(8%)을 보였으나 합병증 발생률이 매우 높고 합병증 발생 시 사망률이 매우 높아 수술주위 감염 예방과 세심한 환자 관리가 필요하다.

Purpose: This study was to evaluate the effects of a physical activity reinforcement program on exercise compliance, depression, and anxiety in continuous ambulatory peritoneal dialysis(CAPD) patients. Method: A nonequivalent control group with a pre-post test was designed. Data collection was done from December, 2002 to June, 2003 at a hoapital. The degree of depression and anxiety of the patients was assessed by the score of SCL-90-R, and exercise compliance was measured by exercise period, frequency, time and intensity. The experimental group was composed of 19 participants who were educated based on an exercise education protocol and carried out walking exercises two to four times a week after hearing verbal persuasion biweekly through the telephone or a face-to-face interview for 12 weeks, while 17 participants in control group received no intervention. Result: 1. The experimental group showed significant improvement in self-efficacy of exercise compliance (U=79.00, p=.01), exercise period ($x^2$=20.84, p=.00), exercise frequency ($x^2$=9.03, p=.0l), exercise time ($x^2$=9.03, p=.0l) and exercise intensity ($x^2$=11.09, p=.00) compared to those of the control group. 2. The experimental group showed a lower depression score (U=84.50, p=.01) than the results of the control group. 3. However, there were no changes in anxiety level compared to the control group. Conclusion: The physical activity reinforcement program was found to have an effect on exercise compliance and the depression score of CAPD patients. The results provided evidence for the importance of physical activity and verbal persuasion in CAPD patients.

Purpose : Dialysis in children with chronic renal failure presents with many difficulies. The purpose of this study is to find an improved method in chronic dialysis in infants and children less than 2 years of age by analyzing the experience with 10 cases. Methods : A retrospective review of the medical records of 10 patients(6 boys and 4 girls) was conducted. The patients had chronic renal failure and underwent chronic dialysis at Samsung medical center from March 1999 to February 2007. Results : At Initiation of dialysis, the median age was 3 months old(22 days-20 months), the median body weight was 3.75 kg(2.2-10.3 kg), and the median serum creatinine level was 4.3 mg/dL(2.0-11.4 mg/dL). The median duration of dialysis was 29.5 months(3-62 months). Dysplastic kidney disease was the most common underlying renal disease. Two patients were treated with hemodialysis, 4 patients with peritoneal dialysis, and 4 patients eventually switched dialysis modality. Nine of the 10 patients took erythropoietin and anti-hypertensive drugs. At the end of the follow up period, 1 patient received kidney transplantation, 2 patients died due to sepsis, and 5 patients were treated with peritoneal dialysis. Two patients were lost to follow up. The most common complication of dialysis was infection. Achieving vascular access and maintaining proper catheter function were the most important factors in treating patients with hemodialysis. The growth status of patients was aggravated after 6 month of dialysis but improved after 1 year of dialysis. Patients showed better growth on peritoneal dialysis than hemodialysis. Conclusion : Chronic dialysis can be performed successfully in infants and children under 2 years of age. Vascular access was the main limitation of hemodialysis, and infection was the common problem in both hemodialysis and peritoneal dialysis. To improve the patients survival rate and quality of life, major efforts should be directed toward the prevention of infection and preservation of catheter function.

Calcification in patients with endstage renal disease on renal replacement therapy can occur in extraskeletal area such as conjunctiva and cornea. Conjunctival and corneal calcification(CCC) has mostly has been reported in adults with endstage renal disease on hemodialysis. CCC seems to be associated with the duration of renal replacement therapy, and high Ca$\times$P value. We report a 10-year-old girl who was on peritoneal dialysis for 31 months and presented with CCC on both eyes. Her corneal calcification was resolved after the epithelial debridement and ethylenediaminetetraacetic acid(EDTA) soaking therapy.

Background: Lung injury that follows bypass has been well described. It is manifested as reduced oxygenation and lung compliance and, most importantly, increased pulmonary vascular resistance reactivity; this is a known cause of morbidity and mortality after repair of congenital heart disease. Injury to the pulmonary vascular endothelium, and its associated alterations of endothelin-1, is considered to be a major factor of bypass-induced lung injury. Removing endothelin-1 after bypass may attenuate this response. This study measured the concentration of serum and peritoneal effluent endothelin-1 after performing bypass to determine if endothelin-1 can be removed via peritoneal dialysis. Material and Method: From March 2005 to March 2006, 18 patients were enrolled in this study Peritoneal catheters were placed at the end of surgery. Serum samples were obtained before and after bypass, and peritoneal effluents were obtained after bypass. Endothelin-1 was measured by enzyme linked immunosorbent assay (ELISA). Result: In the patients with a severe increase of the pulmonary artery pressure or flow, the mean preoperative plasma endothelin-1 concentration was significantly higher than that in the patients who were without an increase of their pulmonary artery pressure or flow (4.2 vs 1.8 pg/mL, respectively, p<0.001). The mean concentration of plasma endothelin-1 increased from a preoperative value of $3.61{\pm}2.17\;to\;5.33{\pm}3.72 pg/ml$ immediately after bypass. After peritoneal dialysis, the mean plasma endothelin-1 concentration started to decrease. Its concentration at 18 hours after bypass was significantly lower than the value obtained immediately after bypass (p=0.036). Conclusion: Our data showed that the plasma endothelin-1 concentration became persistently decreased after starting peritoneal dialysis, and this suggests that peritoneal dialysis can remove the circulating plasma endothelin-1.

당뇨병은 혈액 속에 포도당이 높아져 이에 따른 각종 합병증 때문에 심각한 후유증을 초래할 수 있는 질환이다. 이 중에서 신장 합병증은 중요한 당뇨병 합병증 가운데 하나이다. 당뇨병성 신증은 거의 모든 당뇨병환자에게서 나타난다. 당뇨병성 신증의 마지막은 신장 기능이 거의 다 망가져 혈액투석이나 복막투석을 받는 말기신부전 환자의 가장 흔한 원인이 바로 당뇨병이므로 당뇨병의 신장 합병증을 줄이는 것이 환자의 삶의 질과 직결되는 문제라 할 수 있다. 신장합병증은 초기에는 증상이 잘 나타나지 않아 항상 주의가 필요하다. 신장이 손상되기 시작하면 단백뇨가 계속 나오고 혈압이 오르며 빈혈이 발생하고 몸이 붓는다. 이런 현상은 포도당의 대사물질이 사구체에 쌓이기 때문이다. '사구체'란 신장 안에서 오줌을 거르는 일을 하는 모세혈관 조직으로 일단 손상되면 회복되지 않고 진행되며 이 상태를 그대로두면 결국 더 이상 신장에서 혈액의 노폐물을 걸러내지 못하는 만성 신부전증으로 진행하게 되는 것이다.

Purpose: The aims of this study were to assess the clinical and laboratory profiles of chronic kidney disease-mineral bone disorder (CKD-MBD) and to assess the effects of treatment of active vitamin D analogs on severe hyperparathyroidism (SHPT) in pediatric patients on chronic peritoneal dialysis. Methods: This is a retrospective study included 53 patients who had been undergoing dialysis for more than 1 year, between January 2003 and December 2012. Results: Even after treatment with phosphate binders and active vitamin D analogs, the $mean{\pm}standard$ deviation of the percentage of time during peritoneal dialysis that the patients' serum concentrations of phosphorus, corrected total calcium, and parathyroid hormone (PTH) fell within the Kidney Disease Outcomes Quality Initiative recommended ranges was $25.06{\pm}17.47%$, $53.30{\pm}23.03%$, and $11.52{\pm}9.51%$, respectively. Clinical symptoms or radiological signs of CKD-MBD were observed in 10 patients (18.9%). There were significant differences in percentage of time that the serum intact PTH concentration was outside of the recommended range between patients with and without symptoms or signs of CKD-MBD (below recommended range, $11.74{\pm}7.37%$ vs. $40.77{\pm}25.39%$, P <0.001; above the recommended range, $63.79{\pm}27.86%$ vs. $37.09{\pm}27.76%$, P =0.022). Of the 25 patients with SHPT, high-dose alfacalcidol treatment was required in 13 patients that controlled SHPT in 7 of these patients, without marked complications. Conclusion: Despite our efforts to manage CKD-MBD, patients' met the recommended ranges from relevant guidelines at a low frequency. The treatment of high-dose active vitamin D analogs was required in about half of the patients with SHPT and effective in about half of them.
