Purpose: We investigated the clinical outcomes of deceased donor kidney transplantation (KT) using kidneys with terminal acute kidney injury (AKI). Methods: Between February 2000 and December 2013, we performed 202 deceased donor renal transplants from 159 brain dead donors. According to the expanded criteria donor (ECD) and AKI network criteria, we divided 202 recipients into 4 groups: Group I: Non-AKI & standard criteria donor (SCD) (n = 97); group II: Non-AKI & ECD (n = 15); group III: AKI & SCD (n = 52); and group IV: AKI & ECD (n = 38). Results: The incidence of delayed graft function (DFG) was significantly higher in patients with AKI than it was in the non-AKI group (P = 0.008). There were no significant differences among the 4 groups in graft survival (P = 0.074) or patient survival (P = 0.090). However, the long-term allograft survival rate was significantly lower in group IV than it was in other groups (P = 0.024). Conclusion: Allografts from deceased donors with terminal AKI had a higher incidence of DGF than did those from donors without AKI. However, there is no significant difference in graft and patient survival rates among the groups. So, the utilization of renal grafts from ECDs with terminal AKI is a feasible approach to address the critical organ shortage.

Renal transplant recipients who received immunosuporessive agent are in high risk of development Kaposi's sarcoma. In Korea a few report of Kaposi's sarcoma has been pubilshed but any report of intrathoracic Kaposi's sarcoma provedn by open lung biopsy has not been pulbilshed until now. We report a case of intrathoracic Kaposi's sarcoma developed in a 25 year old Korean man, who had been operated renal transplantation due to end stage renal disease and received cyclosporine and prednisolone as immunosuppessive agent, without any other organ involvment and was proven by open lung biopsy. Although discontinuation of immunosuppressive agent, temporary symptomatic and radilolgic improvement were observed, he died 11 days later after open lung biopsy because of intractable resiratory failure.

Cyclosporin A(CsA) is now widely used to treat organ transplant recipients. But CsA has various short-and long-term side effects. Especially, gingival hyperplasia is not easy to resolve since its nature is still unknown. This study discusses the pathogenesis of CsA-induced gingival hyperplasia on the basis of data obtained from light and electron microscopic studies of biopsis from patients on CsA treatment after kidney transplantation. Light microscopically, the multilayered squamous epithelium showed an irregular surface of parakeratosis and deep invaginations in the subepithelial tissue. At lamina propria, we observed bundles of irregularly arranged collagen fiber, some fibroblasts, numerous capillary vessels and a large diffuse infiltration of plasma cells. Ultrastructurally, many fibroblasts, collagen fibers, collagen fibrils were present in lamina propria. On the basis of the data collected, we propose that the morphological features of the dimensional increase in gingival tissue associated with CsA treatment in kidney transplant patients may be considered proliferative fibroblasts, collagen fibers, collagen fibrils in lamina propria.

Purpose: Pneumocystis jirovecii pneumonia occurs in various immunocompromised patients. Despite the prophylaxis strategies in clinical practice, certain patients develop P. jirovecii pneumonia. This study was performed to investigate pediatric cases with P. jirovecii pneumonia in a single center. Methods: We identified pediatric patients younger than 19 years with microbiologically confirmed P. jirovecii pneumonia from January 2000 to February 2014. A retrospective chart review was performed. Results: Fifteen episodes of P. jirovecii pneumonia in 14 patients were identified with median age of 8.3 years (range, 0.4-18.6 years). Among these patients, 11 patients had hematology-oncology diseases, 2 had primary immunodeficiency disorders (one with severe combined immunodeficiency and the other with Wiskott Aldrich syndrome), 1 had systemic lupus erythematosus and 1 received kidney transplant. Four patients were transplant recipients; 1 allogeneic and 2 autologous hematopoietic cell transplant and 1 with kidney transplant. The median absolute lymphocyte count at the diagnosis of P. jirovecii pneumonia was $5,156cells/mm^3$ (range, $20-5,111cells/mm^3$). In 13 episodes (13 of 15, 86.7%), patients were not receiving prophylaxis at the onset of P. jirovecii pneumonia. For treatment, trimethoprim/sulfamethoxazole was given as a main therapeutic agent in all 15 episodes. Steroid was given in 9 episodes (60%). Median treatment duration was 15 days (range, 4-33 days). Overall mortality at 60 days was 35.7% (5 of 14). Conclusion: Majority of our patients developed P. jirovecii pneumonia while not on prophylaxis. Continuous efforts and more data are needed to identify high risk patients who may get benefit from P. jirovecii pneumonia prophylaxis.

이식을 위해서는 수여자와 공여자의 혈액형과 HLA type을 알아야 한다. 통상 ABO 혈액형이 적합한 경우 이식할 수 있으며 HLA 부적합은 근래 큰 문제가 되지 않으나 HLA 부적합이 없는 경우 이식장기의 장기생존률이 높다. PRA(panel reactive antibody)는 수여자가 HLA에 감작되었는지 검사하는 방법이며 이식 전에는 반드시 교차반응 검사를 하여 음성인 경우에만 이식을 진행한다. 이식 전후에 donor specific antibody(DSA)를 검사하여 이식장기에 대한 수여자의 면역반응을 예측 할 수 있다. 근래에는 스테로이드, calcineurin inhibitor(cyclosporine, tacrolimus), azathioprine 또는 mycophenolate mofetil (MMF)의 삼제요법을 주로 사용하며 항림프구 항체 (Thymoglobulin 또는 항IL-2 receptor 항체 basiliximab/daclizumab)을 이용하여 이식 초기에 면역억제상태를 induction하는 경우도 많다.

The field of vascularized composite allografts (VCAs) has undergone significant advancement in recent decades, and VCAs are increasingly common and accepted in the clinical setting, bringing hope of functional recovery to patients with debilitating injuries. A major obstacle facing the widespread application of VCAs is the side effect profile associated with the current immunosuppressive regimen, which can cause a wide array of complications such as infection, malignancy, and even death. Significant concerns remain regarding whether the treatment outweighs the risk. The potential solution to this dilemma would be achieving VCA tolerance, which would allow recipients to receive allografts without significant immunosuppression and its sequelae. Promising tolerance protocols are being studied in kidney transplantation; four major trials have attempted to withdraw immunosuppressive treatment with various successes. The common theme in all four trials is the use of radiation treatment and donor cell transplantation. The knowledge gained from these trials can provide valuable insight into the development of a VCA tolerance protocol. Despite similarities, VCAs present additional barriers compared to kidney allografts regarding tolerance induction. VCA donors are likely to be deceased, which limits the time for significant pre-conditioning. VCA donors are also more likely to be human leukocyte antigen-mismatched, which means that tolerance must be induced across major immunological barriers. This review also explores adjunct therapies studied in large animal models that could be the missing element in establishing a safe and stable tolerance induction method.

서 론 : 신이식을 받은 산모들은 이식 후 면역억제제 사용과 더불어 고혈압, 임신중독증, 감염등이 동반되어 임신의 고위험군으로 알려져 왔으며, 일반 임산부보다 태아 발육 부전 및 저체중아의 출산 확률이 높은 것으로 알려져 있으나 이러한 산모로부터 출생한 환아들의 출생시의 상태 및 그후의 성장 발육 상태에 대한 연구가 거의 없으므로, 본 연구는 신이식 산모로부터 출생한 소아의 평가와 그후의 성장 상태를 알아보고자 하였다. 대상 및 방법 : 1999년 6월까지 연세의료원에서 신이식을 받은 총 1822명중 여자가 561명이었으며 그중 54명이 임신하였다. 그중 출산한 산모 28명 및 이들에서 태어난 환아 29명(남아 16명, 여아 13명)을 대상으로 하여 산모의 임신시 연령, 이식후 임신까지의 기간 및 병력, 임신에 따른 신기능의 변화, 임신중의 합병증의 발생 빈도 등에 대해 후향적 연구를 시행하였고, 이 산모들로부터 출생한 소아의 출생시의 상태 평가 및 현재 성장과 발육 상태등을 조사하였다. 결 과 :산모의 신이식 시행 당시 평균나이는 $27.7{\pm}5.6$세였고, 출산당시 평균나이는 $30.3{\pm}3.8$세로 이식후 임신까지의 평균기간은 $35.9{\pm}23.2$개월 이었다. 신 이식을 받은 산모들은 모두 면역억제제 치료중이 있으며, 임신전부터 15명($52\%$)은 혈압약을 복용하고 있었으며 임신중에는 14명($48\%$)이 복용하였다. 임신 3기경 12명($41\%$)의 산모에서 임신 중독증이 동반되었다. 이외 임신기간중 14명($48\%$)에서 요로감염, 1명에서 양수 과소증이 있었다. 산모의 임신 전$\cdot$후의 평균 혈청 Cr치는 의미있는 변화는 없었다. 대상아의 평균 재태연령은 $36.3{\pm}3.0$주, 출생시 체중은 $2230{\pm}600gm$, 신장은 $45.1{\pm}3.6cm$, 두위는 $31.38{\pm}2.62cm$이었다. 출생당시 전체 환아중 14명($48\%$)이 자궁내 발육 지연이었고, 저출생 체중아는 18명($62\%$), 극소 저출생 체중아는 2명($7\%$)이었으며, 37주 미만의 미숙아는 15명($52\%$)이었다. 대상아의 현재 연령에서 평균 신장 표준편차 점수(Height SDS)는 $0.29{\pm}0.91$이었고, 평균 체중 표준편차 점수는 $0.62{\pm}1.34$이었다. 각 연령군에서 Height SDS가 -1.5이하인 저신장의 경우가 연령이 1세인 환아에서 1명 나타났으며, 대부분 현재 연령에서 정상범위에 속하였다. 대상아의 병력상 1명에서 소변 검사상 잠혈이 발견되어 신조직 검사를 시행하여 양성 재발성 혈뇨로, 다른 1명은 결절성 경화증으로 외래 추적 관찰중이며, 1명은 생후 50일째 패혈증으로 사망하였다. 결 론 : 출생시 저체중아의 발생율이 $62\%$로 높았으며 조산율도 $52\%$로 높았으나 유산율에 있어 인공유산을 제외한 경우 자연 유산이 $5.6\%$로 낮은 빈도를 보였다. 본 연구의 결과는 이들 산모로부터 태어난 환아를 현재 연령에서 신장분포를 평가하였을 때 $96\%$가 정상범위로 정상적인 성장 형태를 취하고 있었고 1명만이 저신장 소견을 보였다. 저신장을 보였던 1명은 현재 나이가 1세이므로 추후 저신장증 여부는 추후 관찰이 필요할 것으로 생각된다. 이로 미루어 철저한 건강관리와 산전관리가 이루어진다면 성공적인 임신이 가능하며 조산 및 저체중아 일 빈도는 높으나 일단 출생 후 추척 관찰한 결과 정상 산모로부터 태어난 아이와 차이 없이 정상 성장, 발육이 가능하다고 사료된다.

The grafting of a kidney has been found to be the best medical treatment for patients who have renal insufficiency failure, but the patients still have experienced much trouble and apprehension. This study was done to further nursing theory developing for patients who have has a kidney graft from another person. The research method followed grounded theory methodology of Strauss and Corbin. The subjects were three female and four male patients. This study done befween Oct. 1997 and Mar. 1998. All of the subjects were interviewed by the author. Interview were done by the long interview technique and observation. In the process of data analysis, 'heart-boiling' was found to be the core phenomenon. The results were composed to 101 concepts. These concepts were grouped into nineteen categories, and then to twelve categories. There were 12 super-class categories as follows ; 'pain', 'heart-boiling', 'experience of dialysis', 'term of admission to a hospital', 'support of other person', 'dependence on God', 'direction', 'negative reaction', 'positive reaction', 'comfortable', 'lacking', 'acceptance'. In this process, 14 hypotheses were derived from the categories as follows ; (1) The more experience with dialysis that the patients have, the stronger the heart-boiling will tend to be. (2) The less experience with dialysis the patients have, the weaker the heart-boiling will tend to be. (3) The longer admission to hospital the patients have, the stronger the heart-boiling will be. (4) The shorter the admission to hospital the patients have, the weaker the heart-boiling will be. (5) The weaker the intense-grief is, the more positive the reaction to heart-boiling the patients wll have. (6) The stronger the intense-grief is, the more negative the reaction to heart-boiling the patients will have. (7) The stronger the support of other persons that the patients have, the more positive the reaction to heart-boiling the patients will have. (8) The weaker the support of other person that the patients have, the more negative the reaction to heart-boiling the patients will have. (9) The stronger the dependence on God that the patients have, the mure positive reaction to heart-boiling the patients will have. (10) The weaker the dependence on God that the patients have, the more negative reaction to heart-boiling the patients will have. (11) The more positive thoughts that the patients have, the more positive reaction to heart-boiling the patinets will have. (12) The more negative thoughts that the patients have, the more negative reaction to heart-boiling the patients will have. (13) The more positive reaction the patients have, the more free from heart-boiling the patients tend to be. (14) The more negative reaction the patients have, the less free from heart-boiling the patients tend to be. From the analysis of observed data and comparing each class, I concluded that there are four formula relation types between reaction of patients and heart-boiling. (1) If patients have the experience of dialysis, have a long term admission to hospital, are strong in heart-boiling, depend on God, have positive thoughts and another's strong support, they experience release by positive reaction to the intense-grief. (2) If patients have the experience of dialysis, have a short term admission to hospital, are weak in heart-boiling, do not depend on God, have negative thoughts, and have few supports from others, they experience attachment to heart-boiling though a negative reaction. (3) If patients have the experience of dialysis, have a long term admission to hospital, are strong in heart-boiling, do not depend on God, and have negative thoughts, they experience attachment to heart-boiling through negative reaction in spite of support from another. (4) If patients have the experience of dialysis, have a long term admission into hospital, are strong in heart-boiling and satisfaction is low, but they have positive thoughts, then they experience acceptance and harmony through the positive reaction to heart-boiling. The results of this study are expected to help the way nurses care for patients who have had a kidney graft from another.
