背景:环孢素A与他克莫司是肾移植后临床广泛应用的免疫抑制剂。 目的:观察他克莫司和环孢素A对肾移植后炎性细胞因子和血脂的影响。 方法:选择首次接受同种异体肾移植后患者112例,随机分为环孢素A组和他克莫司组,移植后分别给予环孢素A+吗替麦考酚酯+糖皮质激素三联疗法与他克莫司+吗替麦考酚酯+糖皮质激素三联疗法。 结果与结论:他克莫司组的1年人/肾存活率、治疗逆转率高于环孢素A组(P < 0.05),急性排斥反应发生率低于环孢素A组(P < 0.05);移植后1个月及1年的血清白细胞介素2,6,8和血糖水平高于移植前(P < 0.05),低于环孢素A组(P < 0.05),血清白细胞介素4,10低于移植前(P < 0.05),高于环孢素A组(P< 0.05);移植后1个月的血清总胆固醇、三酰甘油和低密度脂蛋白胆固醇高于移植前(P < 0.05),但低于环孢素A组(P < 0.05);移植后1年的血清总胆固醇和低密度脂蛋白胆固醇低于环孢素A组(P < 0.05)。说明他克莫司可通过抑制肾移植后炎性细胞因子释放,改善糖脂代谢等途径降低患者的排斥反应,提高肾移植的存活率。  相似文献

背景:足量吗替麦考酚酯联合低剂量他克莫司和皮质激素可能是目前针对肾移植受者的理想治疗方案,该方案因其具有低肾毒性以及较少的不良反应和较强的免疫抑制作用已在临床上开始逐渐普及。 目的:以吗替麦考酚酯联合标准剂量他克莫司加皮质激素为对照,评估吗替麦考酚酯联合低剂量他克莫司加皮质激素在肾移植患者中的疗效和安全性。 方法:210例首次接受单一器官同种异体移植的肾移植成人受者被随机分配到他克莫司标准剂量组(n=104)和他克莫司低剂量组(n=106),并接受12个月的治疗。主要疗效指标包括肾移植后第12个月慢性移植物损伤指数(CADI)以及肾小球滤过率;次要疗效指标主要包括急性排斥反应发生率、治疗失败率以及患者和移植肾的存活率等;同时对新发移植后糖尿病,新发高血压,新发高血脂等安全性指标进行评价。 结果与结论:两组绝大多数患者使用了足量的吗替麦考酚酯(1.5 g/d及以上)。在他克莫司剂量方面,他克莫司标准剂量组大多数受试者的实际血药浓度水平偏低,与低剂量组的实际血药浓度水平类似,由此反映了吗替麦考酚酯联合低剂量他克莫司和皮质激素方案已广泛为目前临床医师接受和使用。因此,两组也表现出类似的疗效和安全性:他克莫司标准剂量组和低剂量组肾移植后12个月肾脏病理改变的平均CADI评分分别为1.82分和2.13分(P=0.081 3),平均肾小球滤过率分别为77.08 mL/min和       80.12 mL/min(P=0.794 9),急性排斥反应发生率分别为2.6%和5.2%(P=0.681 2),患者和移植肾存活率分别高达100%和99.1%(P=1.000 0)。在安全性方面,他克莫司标准剂量组和低剂量组新发移植后糖尿病的比例分别为2.9%和1.9%,新发高血脂的比例分别为2.9%和3.8%。结果显示在吗替麦考酚酯联合他克莫司和皮质激素的肾移植免疫抑制治疗方案中,足量吗替麦考酚酯的使用,可以减少他克莫司的剂量,在保持较强的免疫抑制作用即成功地降低急性排斥反应发生率的同时,显著减少他克莫司所致的肾毒性、高血脂和新发糖尿病等不良反应,较好地达到了疗效和毒性间的平衡。  相似文献

背景:肾移植后长期使用糖皮质激素(以下简称激素)可导致明显的不良反应,少用和不用激素的免疫抑制方案已成为国内外众多肾移植工作者研究的热点。但是,激素减量或撤除存在一定的风险,目前尚未有统一的方案。由于尿微量蛋白在肾小管损伤后可以立刻被检测出来,对肾移植受者而言,监测尿微量蛋白能及早发现移植后肾功能异常,为临床治疗争取时间。 目的:探讨撤除激素(以泼尼松为代表)对肾移植受者发生尿微量蛋白的影响。 方法:35例撤除泼尼松肾移植受者均采用环孢素A或他克莫司+吗替麦考酚酯二联免疫抑制方案,泼尼松开始剂量为30 mg/d,以后逐渐减量(每周减量5 mg),肾移植后1个月停用。其中环孢素A组16例,他克莫司组19例。分别对两组患者肾移植后3,6,12,24个月和加服泼尼松后3,6,12个月进行尿微量蛋白测定与尿蛋白定性测定,同时记录肾移植后2年血肌酐、空腹血糖、体质量增加、急性排斥率、感染、人/肾存活率与加服激素前后24 h尿蛋白定量情况。 结果与结论:两组撤除泼尼松后6个月,尿α1-微球蛋白开始升高;12个月,尿微量白蛋白、尿α1-微球蛋白、尿转铁蛋白明显升高,其中尿蛋白阳性:环孢素A组5例,他克莫司组3例;24个月时,尿微量白蛋白、尿α1-微球蛋白、尿转铁蛋白、尿免疫球蛋白(Ig)G均明显升高,其中尿蛋白阳性:环孢素A组11例,他克莫司组10例,其24 h尿蛋白定量均大于1 g。在此基础上两组加服激素后6个月,尿α1-微球蛋白、尿微量白蛋白开始下降,各1例尿蛋白转阴;12个月,尿微量白蛋白、尿α1-微球蛋白、尿转铁蛋白均下降,尿蛋白转阴:环孢素A组2例,他克莫司组3例,24 h尿蛋白定量在0.7 g左右。肾移植后2年时,环孢素A组血肌酐、急性排斥率高于他克莫司组(P < 0.05),空腹血糖、体质量增加、感染、人/肾存活率两组均无明显差异。结果表明撤除泼尼松对肾移植受者尿微量蛋白的出现影响较大,尤其在肾移植后2年,尿微量白蛋白、尿α1-微球蛋白、尿转铁蛋白、尿免疫球蛋白(Ig)G均明显升高,其安全性有待进一步探讨。 中国组织工程研究杂志出版内容重点:肾移植;肝移植;移植;心脏移植;组织移植;皮肤移植;皮瓣移植;血管移植;器官移植;组织工程全文链接:  相似文献

背景:近年来,多项研究表明环孢素A转换成他克莫司的免疫抑制方案对慢性移植肾肾病有一定疗效。 目的:探讨他克莫司替换环孢素A联合雷公藤多甙片治疗慢性移植肾肾病的疗效及安全性。 方法:回顾性分析经临床及病理证实为慢性移植肾肾病的患者57例,诊断前均采用环孢素A+吗替麦考酚酯+泼尼松免疫抑制治疗,然后根据不同的治疗方案分成两组:环孢素A组(n=27),继续采用原方案治疗;他克莫司+雷公藤多甙片组(n=30),环孢素A切换成他克莫司的同时再联用雷公藤多甙片治疗。 结果与结论:转换后3,6个月两组间血肌酐、24 h尿蛋白水平比较差异均有显著性意义(P < 0.05),各组3个月与6个月的血肌酐、24 h尿蛋白水平比较差异均无显著性意义(P > 0.05),血总胆固醇、三酰甘油、丙氨酸氨基转换酶、天冬酸氨基转换酶等指标两组间差异无显著性意义(P > 0.05)。他克莫司+雷公藤多甙片组震颤发生率较环孢素A组高(P < 0.05),但高血压、多毛症、血糖升高、牙龈增生的发生率显著低于环孢素A组(P < 0.05)。结果表明他克莫司替换环孢素A联合雷公藤多甙片的治疗方案对慢性移植肾肾病有显著的疗效,且安全性能好,有助于移植肾的长期存活。  相似文献

背景:免疫抑制药物日新月异的发展及药物应用存在较大的个体差异使得目前国内外对于肾移植后免疫抑制的选择和应用剂量等仍无法达成完全统一的共识。 目的:观察以低剂量他克莫司为基础的四联免疫抑制剂方案的免疫抑制效能、保护肾功能的作用和安全性。 方法:以他克莫司+酶酚酸酯+泼尼松龙(方案1)为对照组;将方案1中他克莫司和酶酚酸酯减量为方案2,以方案2+西罗莫司为组1;方案2+咪唑立宾为组2。检测3组受者肾移植后第2,4周、6个月及1年时淋巴细胞对供体树突状细胞的反应强度;每6个月测定1次受者尿转化生长因子β1;移植后每1~3个月检查肝肾功能、血尿常规、血糖,随访时间为4年。 结果与结论:3组急性排斥反应发生率及感染发生率无显著差异;移植4周,组1,组2的反应强度明显低于对照组 (P < 0.05);移植1年,组1、组2尿转化生长因子β1浓度均显著低于对照组(P < 0.05);移植2年,组1、组2血肌酐和肌酐清除率降低值均显著低于对照组(P < 0.05);组1、组2肝功损害、高血糖等不良反应发生率均低于对照组 (P < 0.05)。提示与常规剂量他克莫司为基础的三联免疫抑制方案相比,低剂量他克莫司为基础的四联免疫抑制方案能够发挥同样的免疫抑制效果,同时能减轻移植肾纤维化进程,改善移植肾功能,减少严重不良反应发生率,更有利于移植肾长期存活。  相似文献

Background:

The toe to hand transplantation is a method of reconstruction on the unique or multiple amputations of the fingers. It can be used the whole toe or with certain modifications as a wrap-around flap from the big toe or fingertip. It is a widely accepted option for the thumb.

Methods:

It is a series of patients with amputation of one or more fingers of the hand were operated with second toe to hand transplantation. The survival was evaluated and the sensory recovery by 2-point discrimination.

Results:

We practiced 12 transplants, 8 thumb, and 4 in other fingers. Ten were adults and two children. All transplants survived. Two patients required tenolysis flexor. The sensibility was recovered with good 2-point discrimination of 8 mm.

Discussion:

In the more proximal finger amputations, a second toe is the most appropriate, with lower morbidity of the donor site. The rates of success are between 95 to 100%. We had a success rate of 100%. The resulting defect is in the foot is minimum when the second toe was used. The decision to use one of these techniques depends on the decision and transplant surgeon training. We always used the second toe for transfers to the hand, considering that it will be thinner than the original thumb; our patients had no complaint about the appearance.

Conclusion:

Toe-to-hand transplantation is a good technique, providing a very good aesthetic appearance and allowing the recovery of sensitivity. The defect that is created in the foot does not produce significant aesthetic and functional alterations.  相似文献

Objective

Heart or lung transplantation is a complex intervention requiring medication adherence. The objective of this systematic review is to estimate the prevalence of non-adherence (NA) with post-transplantation medication in heart or lung recipients and to assess its clinical impact. We examined in the selected studies if the authors considered the patient's perspective in their evaluations.

Methods

The electronic database MEDLINE, EMBASE and The Cochrane Central Register were searched. Only studies that reported the number of non-adhere subjects were eligible. The different methods of measurement, the ways in which authors defined NA and if authors had integrated patient's perspective in their secondary objectives were also assessed.

Results

The range frequency of NA was 1-42.9% for all drugs. Non-adherent patients tend to experience worse outcomes compared to adherent patients. The patient's perception of drug side-effects is the most reported patient-related factor for impairing adherence.

Conclusion

NA after heart or lung transplantation is an important issue and concerns not only immunosuppressant treatments. The main striking point of the selected studies is the lack of patient perspective and the omission of patients-healthcare providers’ relationship.

Practice implications

Future research must focus on patients’ motivation for the medication-taking behaviour.  相似文献

Over the last decade, liver transplantation has become an operational reality in our part of the world. As a result, clinicians working in an intensive care unit are more likely to be exposed to these patients in the immediate postoperative period, and thus, it is important that they have a working knowledge of the common complications, when they are likely to occur, and how to deal with them. The main focus of this review is to address the variety of critical care issues in liver transplant recipients and to impress upon the need to provide favorable circumstances for the new liver to start functioning and maintain the function of other organs to aid in this process.  相似文献

Although small bowel transplantation (SBT), or pancreas-spleen transplantation (PST) often lead to lethal graft-versus-host reaction (GVHR) in experimental animals, fatal GVHR is rare after clinical liver transplantation. This study describes a modified model of SBT and PST in the rat using cuff techniques applied to the renal artery and vein of the recipient. The ability of LEW (RT1(1)) or BN (RT1n) lymphocytes accompanying intestinal, splenic, or hepatic grafts to induce lethal GVHR in (LEW x BN) F1 hybrid recipients was compared. SBT and PST experiments showed that lethal GVHR always occurred in LEW-into-F1 combination, but was much less frequent in BN-into-F1 SBT. In mixed lymphocyte reaction (MLR), LEW mesenteric or splenic T cells showed significantly higher proliferative responses against BN stimulators than did BN mesenteric or splenic T cells against LEW. Adoptive cell transfer experiments using mesenteric or splenic cells also showed that LEW cells were higher responders than BN. In contrast with SBT and PST results, a lethal GVHR was not induced after liver or pancreas grafting alone in either parent-to-F1 combination. In MLR, hepatic T cells from either parent failed to elicit a proliferative response against allostimulators. These results indicate that the occurrence of lethal GVHR is dependent upon the reactivity of parental lymphocytes against allo-antigenicity of F1 hybrids and also upon the lymphoid tissue transplanted. The lack of alloreactivity of hepatic T cells accounts for the absence of lethal GVHR after liver grafting.  相似文献

Current theory holds that macrochimerism is essential to the development of transplant tolerance. Hematopoietic cell transplantation from the solid organ donor is necessary to achieve macrochimerism. Over the last 10–20?years, trials of tolerance induction with combined kidney and hematopoietic cell transplantation have moved from the preclinical to the clinical arena. The achievement of macrochimerism in the clinical setting is challenging, and potentially toxic due to the conditioning regimen necessary to hematopoietic cell transplantation and due to the risk of graft-versus-host disease. There are differences in chimerism goals and methods of the three major clinical stage tolerance induction strategies in both HLA-matched and HLA-mismatched living donor kidney transplantation, with consequent differences in efficacy and safety. The Stanford protocol has proven efficacious in the induction of tolerance in HLA-matched kidney transplantation, allowing cessation of immunosuppressive drug therapy in 80% of study participants, with the safety profile of conventional transplantation. In HLA-mismatched transplantation, multi-lineage macrochimerism of over a year’s duration can now be consistently achieved with the Stanford protocol, with complete withdrawal of immunosuppressive drug therapy during the second post-transplant year as the next experimental step and test of tolerance.  相似文献

To identify favored choice of transplantation in patients with acute promyelocytic leukemia (APL) in second complete remission, we studied 294 patients with APL in second complete remission (CR2) receiving allogeneic (n = 232) or autologous (n = 62) hematopoietic cell transplantation (HCT) reported to the Center for International Blood and Marrow Transplantation Research (CIBMTR) from 1995 to 2006, including 155 with pre-HCT PML/RAR∝ status (49% of allogeneic and 66% of autologous). Patient characteristics and transplantation characteristics, including treatment-related mortality, overall survival (OS), and disease-free survival, were collected and analyzed for both univariate and multivariate outcomes. With median follow-up of 115 (allogeneic) and 72 months (autologous), 5-year disease-free survival (DFS) favored autologous with 63% (49% to 75%), compared with allogeneic at 50% (44% to 57%) (P = .10). OS was 75% (63% to 85%) versus 54% (48% to 61%) (P = .002), for autologous and allogeneic transplantation, respectively. Multivariate analysis showed significantly worse DFS after allogeneic HCT (hazard ratio [HR], 1.88; 95% confidence interval [CI], 1.16 to 3.06; P = .011) and age > 40 years (HR, 2.30; 95% CI, 1.44 to 3.67; P = .0005). OS was significantly worse after allogeneic HCT (HR, 2.66; 95% CI, 1.52 to 4.65; P = .0006); age > 40 (HR, 3.29; 95% CI, 1.95 to 5.54; P < .001), and first complete remission < 12 months (HR, 1.56; 95% CI, 1.07 to 2.26; P = .021). Positive pre-HCT PML-RAR∝ status in 17 of 114 allogeneic and 6 of 41 receiving autologous transplantation did not influence relapse, treatment failure, or survival in either group. The survival advantage for autografting was attributable to increased treatment-related mortality (TRM) in the allogeneic group of 30% compared to 2% in the autologous group, in addition to the added mortality associated with GVHD. We conclude that autologous HCT yields superior OS for APL in CR2. Long-term DFS in autologous recipients, even with minimal residual disease–positive grafts, remains an important subject for further study.  相似文献

Anatomic bases for liver transplantation   总被引:1,自引:0,他引:1  
Summary This study gathers the anatomic implications for a good liver transplantation. During hepatic removal a left hepatic a.exists in 20% of cases; a right hepatic artery originating from the superior mesenteric a. (SMA) can be the only arterial supply in 9% of cases; the whole lesser omentum has to be removed and the SMA from 6 cm to its origin. The SMA must be freed from the celiac ganglia and its ostium removed with the celiac trunk in an aortic patch cut on the anterior side in order to avoid the renal ostia. During total hepatectomy, dissection of the portal triad is often difficult because of portal hypertension dilating accessory portal veins (parabiliary arcade) and pedicular lymphatics. Nerve plexuses are thick in front of the hepatic artery or behind the portal triad. Transection of triangular ligaments leads to the retrohepatic inferior vena cava (IVC) that must be freed from its posterior tributaries (right suprarenal vein and inferior phrenic veins flowing either into the IVC or into the hepatic veins). One big problem during hepatic replacement is the biliary anastomosis which must be well irrigated. In the recipient, dissection up to the hilum preserves hepatic and pancreatico-duodenal pedicles. The biliary tract of the graft must be cut low, behind the pancreas, and several centimeters of the gastroduodenal artery must be preserved to save hepatic and gastroduodenal pedicles.
Bases anatomiques de la transplantation hépatique
Résumé Ce travail rassemble les notions anatomiques nécessaires au bon déroulement d'une transplantation hépatique. Le prélèvement du greffon doit enlever tout le petit omentum contenant une éventuelle a. hépatique gauche née de l'a. gastrique gauche (20%) et emporter l'a. mésentérique supérieure jusqu'à 6 cm de son origine pour ne pas oublier une a. hépatique droite née de cette dernière: son ostium est pris avec le tronc clique dans un patch aortique découpé sur la face antérieure. Lors de l'hépatectomie totale, la dissection du pédicule hépatique est rendue délicate par l'hypertension portale qui dilate les veines portes diets accessoires (arcade parabiliaire) et les lymphatiques pédiculaires. Les plexus nerveux sont riches devant l'artère hépatique et derrière le pédicule. La section des ligaments triangulaires droit et gauche amène à la veine cave inférieure (VCI) rétro-hépatique qu'il faut libérer de ses afférences postérieures (en particulier la veine surrénale principale droite toujours haut située et les veines phréniques inférieures qui s'abouchent soit dans la VCI soit dans les veines hépatiques du carrefour). Lors du remplacement, l'anastomose biliaire doit être vascularisée. Chez le receveur la dissection jusqu'au hile permet de conserver les pédicules. La voie biliaire du greffon doit être coupée bas derrière le pancréas et les premiers centimètres de l'artère gastro-duodénale conservés pour préserver les pédicules hépatique et pancréaticoduodénal.

Despite the prevalence and known adverse impacts of depression after hematopoietic cell transplantation (HCT), little is known about the trajectory of depression occurring after HCT, or which pretransplantation risk factors might help predict new or worsening post-HCT depression. This secondary analysis evaluated the relationships between pre-HCT patient-reported outcomes and demographic characteristics and post-HCT depression. A total of 228 adult HCT patients were evaluated pre-HCT (T1) and again at 6 to 7 weeks post-HCT (T2), using touch-screen computers in the transplantation clinic during participation in a larger trial. Measures evaluated included the Symptom Distress Scale, the EORTC QLQ-C30 for quality of life, a single-item pain intensity question, and the Patient Health Questionnaire 9 for measurement of depression. At T1, rates of depression were quite low, with only 6% of participants reporting moderate or higher depression. At T2, however, the prevalence of moderate or higher depression was 31%. We observed a strong linear relationship in PHQ-9 scores between T1 and T2 (P < .0001). Depression score at T1 was a significant predictor of depression score at T2 (P = .03), as was poorer emotional function at T1 (P < .01). Our results indicate that post-HCT depression is common, even in patients with a low pre-HCT depression score. Frequent screening for symptoms of depression at critical time points, including 6 to 7 weeks post-HCT, are needed in this population, followed by referrals to supportive care as appropriate.  相似文献
