  • Despite reports suggesting that tissue-resident natural killer (trNK) cells cause ischemic kidney injury, their contribution to the development of tubulointerstitial fibrosis has not been determined. This study hypothesized that the depletion of trNK cells may ameliorate renal fibrosis by affecting transglutaminase 2/syndecan-4 interactions. Aristolochic acid nephropathy (AAN) was induced in C57BL/6 mice as an experimental model of kidney fibrosis. The mice were treated with anti-asialo GM1 (ASGM1) or anti-NK1.1 antibodies to deplete NK cells. Although both ASGM1 and NK1.1 antibodies suppressed renal $NKp46^+DX5^+$ NK cells, renal $NKp46^+DX5^-$ cells were resistant to suppression by ASGM1 or NK1.1 antibodies during the development of tubulointerstitial fibrosis in the AAN-induced mouse model. Western blot analysis showed that both antibodies increased the expression of fibronectin, transglutaminase 2, and syndecan-4. These findings indicate that trNK cells played an exacerbating role in tubulointerstitial fibrosis by activating transglutaminase 2 and syndecan-4 in the AAN-induced mouse model.

  • Doing CABG in patient with renal transplantation requires special concern to keep and preserve renal function safely during and after operation. We experienced two cases of CABG for treatment of myocardial ischemia. who underwent renal transplantation 2 and 3 years ago respectively. The first patient received single reversed saphenous vein graft at LAD and second one received double saphenous vein graft at LAD and OMI. Peri & postoperative urinary volume and renal function test were comparable with preoperative status in both cases. Although abnormal lipid metabolism due to long term use of immunosuppressive regimen act a causative role in development and progression of coronary artherosclerosis in renal transplantation patient, CABG can be done safely with some precaution including maintenance of adequate mean blood pressure and blood level of immunosupressive regimen during cardiopulmonary bypass.

  • 국소 분절성 사구체 경화증은 소아 말기 신부전의 중요한 원인이며, 신이식 후에도 재발되는 특징을 보이는데, 이러한 재발에 대한 치료로는 혈장교환술과 사이클로스포린과 같은 면역억제제의 투여 등이 있다. 이에 저자들은 신이식 전 혈장교환술과 예방적 사이클로스포린을 투여하여 국소 분절성 사구체 경화증의 재발을 효과적으로 예방한 경험 2례를 보고하는 바이다.

  • Oligomeganephronia is a rare congenital form of bilateral renal hypoplasia histologically characterized by reduction in number and hypertrophy of nephrons. Clinically, this condition is presented in early infancy with vomiting, polyuria, polydipsia and dehydration. The problems are readily corrected, but slowly progressive renal failure follows accompanied by failure to thrive, short stature, and renal osteodystrophy. We experienced three cases of oligomeganephronia. Case 1. : A 3 2/12 years old female child was incidentally diagnosed as renal failure at age of 2 months when she was hospitalized due to pneumonia. She had open renal biopsy and was diagnosed as bilateral dysplastic kidney. On OPD follow-up, she progressed to end-stage renal failure (BUN/Cr 114/4.6 mg/dl) and had renal transplantation. The specimen was shrunk remarkably and light microscopy showed oligomeganephronia. Case 2. : A 14 8/12 years old female child with proteinuria was detected in an annual urine screening program for school children, she was diagnosed as renal failure (BUN/Cr 33.9/4.1 mg/dl), and had $5{\times}4{\times}3\;cm$ sized mass on abdominal CT scan. She had renal biopsy, and the specimen showed oligomeganephronia. She had hemodialysis for six months, and renal transplantation along with bilateral nephrectomy was performed. Case 3. : A 14 8/12 years old male child was diagnosed having chronic nephritis and chronic renal failure at 3 years old, progressed to end-stage renal failure (BUN/Cr 87/9.6 mg/dl) on OPD follow-up, and had a rephrectomy and renal transplantation. The biopsy specimen showed oligomeganephronic hypoplasia, secondary focal segmental glomerolosclerosis, and chronic interstitial nephritis. We report 3 cases of oligomeganephronia that progressed to end-stage renal failure and had successful renal transplantation with a brief review of related literatures.

  • Purpose: This study was aimed to investigate the health related quality of life and related factors of organ transplant recipients. Method: The participants were 188 people who had liver(86), kidney(81), or heart(24) transplanted. Data on the demographic characteristics, transplantation-related characteristics, symptom frequency or discomfort measured by Transplant Symptom Frequency and Symptom Distress Scale by Lough et al(l987), and health related quality of life measured by SF-36(version 2) were collected. Result: Overall health related quality of life score was 492.1 for 100scoring and, 344.9 for norm based. Physical functioning showed the highest quality of life score (77.5) and vitality showed the lowest(51.l). The kidney transplanted showed the highest quality of life (504.4) and the heart transplanted showed the lowest(426.7) Quality of life was related with occupation(p=.016) and symtom discomfort(p < .0001). Conclusion: The health related quality of life of transplated patients was lower than the norm of American. Further studies need to be done to identify the norm of Korean and to investigate the effect of releving symptom discomfort on the increasing the health related quality of life.

  • 목적: 본 연구의 목적은 뇌사자로부터 공여받은 신장을 이식한 대상자들이 프레드니손을 생체이식 대상자들보다 더 많이 투여받는 임상상황에서 프레드리손이 근력과 일상생활활동에 영향을 주는지 규명하기 위함이다. 방법: 연구 대상은 뇌사자로터 신장을 응급으로 수여받은 32명이었으며 모두 혈액투석을 하고 있었다. 이식 수술 전날, 환자의 일반적인 정보, 근력, 일상생활활동에 대해 조사하였으며 이식수술 후 12주째 되는 날 외래에서 근력과 일상생활활동을 다시 조사하였다. 프레드니손 용량은 임상기록지를 통해 수집하였다. 연구결과: 신장이식술 후 12주의 근력은 고관절 신전근력을 제외하고는 유의하게 감소되지 않았다. 그러나 신장이식 후 12주의 일상생활활동은 수술 직전보다 유의하게 감소된 것으로 나타났다. 근력은 혈액투석을 시행한 기간에 의한 영향을 더 받았으며 일상생황활동의 저하는 3개월간 활동을 제한하는 퇴원교육의 영향이 큰 것으로 볼 수 있다. 결론: 본 연구에서 대상자의 근력과 일상생활활동은 프레드니손 투약의 영향을 받지 않았으며 오히려 혈액투석을 시행했던 기간에 따라 영향을 받은 것으로 나타났다. 따라서 혈액투석 환자들의 근력 증진을 위한 간호중재 개발이 필요하다.

  • Disseminated adenovirus infection can result in high mortality and morbidity in immunocompromised patients. Here, we report the case of a 10-year-old renal allograft recipient who presented with hematuria and dysuria. Adenovirus was isolated from his urine. His urinary symptoms decreased after intravenous hydration and reduction of immunosuppressants. However, 2 weeks later he presented with general weakness and laboratory tests indicated renal failure necessitating emergency hemodialysis. Adenovirus was detected in his sputum; therefore, intravenous ganciclovir and immunoglobulin therapy were initiated. Renal biopsy revealed diffuse necrotizing granulomatous tubulointerstitial nephritis compatible with renal involvement of the viral infection. Adenovirus was detected in his serum. Despite cidofovir administration for 2 weeks, adenovirus was also detected in the cerebrospinal fluid, resulting in generalized tonic-clonic seizure. The patient died 7 weeks after the onset of urinary symptoms. Adenovirus should be considered in screening tests for post-renal transplantation patients who present with hemorrhagic cystitis.

  • 긴 잔여 수명을 가진 소아-청소년기에 발생한 만성 콩팥병의 진행을 억제하는 것은 매우 중요하다. 콩팥 기능의 변화는 공식을 이용하여 혈청 크레아틴이나 시스타틴 C 치를 이용한 사구체 여과율의 추정치를 계산하는 것이 비교적 정확하고 편리하다. 고혈압과 단백뇨는 엄격하게 조절되어야 하며 빈혈은 에리트로포이에틴으로 교정되어야 한다. 혈압이 정상인 경우에도 특별한 금기사항이 없는 한 ACE 억제제나 안지오텐신 수용체 차단제를 사용하는 것이 필요하나 부작용의 발생에 주의할 필요가 있다. 만성 콩팥병의 진행 억제를 위한 노력은 만성 콩팥병이 확인되는 대로 가능한 일찍 시작되어야 하며 콩팥 이식을 받을 때까지 잔여 신기능이 남아 있는 한 계속되어야 한다. 온라인 한국 소아 만성 콩팥병 등록 시스템이 만성 콩팥병의 진료에 도움을 준다.

  • 본과에서는 신장 이식자에서 매우 드물게 발현되는 구강내의 카포시 육종을 경험하였으며 이와 같이 장기 이식 후 면역 억제제를 투여하는 환자에서 구강내 카포시 육종의 발현시에는 전신적으로 이환된 경우가 많으므로 특별한 주의를 요하리라 사료된다.
