背景:西罗莫司替代钙调磷酸酶抑制剂治疗肾移植后钙调磷酸酶抑制剂肾毒性和慢性移植肾肾病,转换对象的选择和时机至关重要。
目的:观察不同血肌酐水平下应用西罗莫司替代钙调磷酸酶抑制剂治疗肾移植患者钙调磷酸酶抑制剂肾毒性和慢性移植肾肾病的临床效果。
方法:选择肾移植后确诊钙调磷酸酶抑制剂慢性肾毒性和慢性移植肾肾病患者,根据转换前血肌酐≤220 μmol/L和血肌酐> 220 μmol/L,各分为钙调磷酸酶抑制剂肾毒性组、慢性移植肾肾病组和钙调磷酸酶抑制剂维持组;前两组将原有免疫抑制方案中钙调磷酸酶抑制剂转换为西罗莫司,转换组共53例,钙调磷酸酶抑制剂维持患者为对照组共28例,随访3年。动态观察各组在不同随访时间点的血肌酐水平及不良事件发生率,并在随访终点共行移植肾穿刺活检9例。
结果与结论:转换前血肌酐≤ 220 μmol/L钙调磷酸酶抑制剂肾毒性组、慢性移植肾肾病组血肌酐值,在随访第24、36个月血肌酐较转换前明显降低(P < 0.05),钙调磷酸酶抑制剂维持组血肌酐呈缓慢爬行上升高于前两组(P < 0.05)。血肌酐> 220 μmol/L钙调磷酸酶抑制剂肾毒性组血肌酐转换后显著下降(P < 0.05);后两组转换后血肌酐呈爬行上升(P < 0.05)。转换后主要不良事件有轻度贫血(30.2%)、高脂血症(35.8%)、白细胞低下(22.6%)等。肾移植后血肌酐爬行升高转换西罗莫司方案疗效显著,转换前穿刺活检确诊钙调磷酸酶抑制剂肾中毒还是慢性移植肾肾病,并结合血肌酐水平综合判断是否行西罗莫司转换治疗,注意监测血脂水平;转换应在移植肾功能发生严重损害前进行,早期转换,患者将获益更大。

慢性乙型肝炎患者肝组织中HBV抗原表达特征及其临床意义 总被引:5,自引:0,他引:5
目的探讨慢性乙型病毒性肝炎肝活检组织中检测乙肝表面抗原(HBsAg)和乙肝核心抗原(HBcAg)表达强度及表达方式的必要性。方法采用EnVision免疫组织化学法检测196例慢性乙型肝炎患者肝穿组织中HBsAg和HBcAg的表达水平,并用荧光定量PCR检测其血清中的HBV DNA的含量。对肝组织进行炎症活动度分级和纤维化分期。结果肝组织中的HBsAg表达强度和表达方式与炎症分级、纤维化分期和血清乙肝病毒载量均无相关性(P>0.05)。HBcAg表达强度与炎症分级无相关性(r=-0.02,P>0.05);与纤维化分期呈负相关(r=-0.28,P<0.01);与血清乙肝病毒载量呈正相关(r=0.53,P<0.01)。HBcAg表达方式与炎症分级为负相关(r=-0.27,P<0.01),其中浆型组炎症活动度分级高于核型组和混合型组(P<0.01),混合型组高于核型组(P<0.01)。HBcAg表达方式与纤维化分期亦呈较弱的负相关(r=-0.23,P<0.01),其中浆型组纤维化分期高于核型组和混合型组(P<0.05)。HBcAg表达方式与血清乙肝病毒载量呈正相关(r=0.22,P<0.01)。结论区分肝组织中的HBsAg表达强度和表达方式无益于了解慢性乙型肝炎患者肝损害的程度,而检测肝组织中的HBcAg则有助于临床抗病毒治疗。 相似文献

背景:肾移植后慢性排斥反应及各种移植肾病变是移植肾失功能的常见原因,但对移植肾予以准确评估往往非常困难,活检仍是目前的主要手段。
目的:分析肾移植后出现合并症时移植肾穿刺活检的病理结果。
方法:对72例移植肾进行肾穿刺活组织检查,并进行病理诊断及分类,结合移植后情况进行分析。
结果与结论:72例中发生急性细胞介导性排斥反应35例,急性抗体介导性排斥反应12例,移植肾急性药物毒性损伤10例,慢性T细胞介导性排斥反应6例,慢性抗体介导性排斥反应2例,急性肾小管坏死4例,慢性移植肾肾病3例。移植肾组织活检的病理报告与穿刺前临床诊断的符合率在75%以上。移植肾穿刺活检未发生明显的不良反应。提示移植肾活检安全可靠,对肾移植后难以根据临床化验资料作出准确判断肾脏损害的并发症及治疗方案的选择有极为重要的指导意义。 相似文献

背景:目前,肾移植病理学检查仍为移植肾慢性排斥反应的“金标准”,但肾移植程序性活检在中国尚难以普及,且存在一定的风险;由于诸多原因,使患者慢性排斥反应早期因未及时发现而错失治疗时机。
目的:观察肾移植慢性排斥反应大鼠血浆中间α胰蛋白酶抑制剂的水平。
方法:实验以正常雄性Wistar大鼠为供体,正常雄性SD大鼠为受体进行肾移植。移植后分为慢性排斥反应组和正常肾移植组。慢性排斥反应组受体于移植前3 d起,每日给予腹腔注射环孢素A微乳化剂2 mg/kg,正常肾移植组则每日给予环孢素A微乳化剂腹腔注射5 mg/kg。
结果与结论:移植后4,6,8,10,12周,Western blot检测结果显示,与移植前1周相比,正常肾移植组和慢性排斥反应组间α胰蛋白酶抑制剂蛋白表达量明显降低(P < 0.01)。移植后第4,6周,慢性排斥反应组间α胰蛋白酶抑制剂蛋白表达高于正常肾移植组(P < 0.01),而在8,10,12周低于正常肾移植组(P < 0.01)。慢性排斥反应组血浆间α胰蛋白酶抑制剂呈时间依赖性下降(P < 0.01)。结果证实,大鼠肾移植后出现慢性排斥反应时,血浆α胰蛋白酶抑制剂水平显著下调。间α胰蛋白酶抑制剂水平变化与肾移植慢性排斥反应关系密切,可为肾移植后慢性排异反应的预测提供参考依据。 相似文献

背景:肝移植后受者体内绝大部分病毒负荷被清除,植入新肝后其复发性肝炎病原体从肝外进入肝内的途径及其复制规律目前尚无定论。
目的:检测肝移植前后外周血单个核细胞和肝组织中乙型肝炎病毒cccDNA及血清中乙型肝炎病毒DNA的表达。
方法:采用淋巴细胞分离液从乙肝病毒相关终末期肝病37例患者外周血中分离出单个核细胞,采用荧光定量PCR检测肝移植前后及移植后乙肝复发3个时期外周血单个核细胞和肝组织中cccDNA及血清乙型肝炎病毒DNA表达。
结果与结论:肝移植前,单个核细胞cccDNA阳性12例,肝组织cccDNA阳性6例,检出率分别为32%和16%,单个核细胞、肝组织中cccDNA拷贝范围分别为(3.028~6.508)×104,(4.158~6.234)×104 拷贝/mL。肝移植后,单个核细胞cccDNA阳性1例,无血清乙型肝炎病毒DNA检测阳性病例。6例肝移植后乙肝复发病例中外周血单个核细胞cccDNA阳性4例,肝组织活检cccDNA阳性1例,6例血清乙型肝炎病毒 DNA均为阳性。提示乙肝病毒相关终末期肝病患者肝移植后乙肝复发途径可能是残留乙肝病毒在外周单个核细胞中以cccDNA为模板复制,然后再迁移到肝脏。 相似文献

背景:经门静脉及经肝动脉是胰岛移植治疗1型糖尿病的2种途径,经门静脉途径并发症较多,经肝动脉移植创伤小,并发症少,但缺乏深入研究。
目的:对经肝动脉及经门静脉异种胰岛移植治疗糖尿病恒河猴模型的疗效进行比较。
方法:将18只恒河猴糖尿病模型分成经肝动脉组(n=6)、经门静脉组(n=9)及对照组(n=3)。经肝动脉组采用Seidinger技术肝动脉插管经导管植入处理好的新生猪胰岛(50 000胰岛当量/kg);经门静脉组在超声引导下门静脉穿刺经导管植入处理好的新生猪胰岛(50 000胰岛当量/kg);对照组2只经门静脉穿刺注入门静脉组等量生理盐水,1只经肝动脉注入肝动脉组等量生理盐水。各组均使用相同免疫抑制方案。
结果与结论:肝动脉组及门静脉组外源性胰岛素的用量较移植前分别平均减少约59.53%,48.39%,2组间外源性胰岛素减少的百分比差异无显著性意义(P > 0.05);肝动脉组及门静脉组血清猴C-肽一直保持在较低的水平,而血清猪C-肽的水平逐渐升高,2组之间血清猪C-肽浓度差异无显著性意义(P > 0.05),但门静脉组因移植后不同并发症出现4/9只糖尿病猴死亡,而肝动脉组仅因穿刺点渗血死亡1只,提示经肝动脉肝内移植途径操作较经门静脉途径更安全、简便,并发症及不良反应小,移植物均能长期成活并发挥生理功能。 相似文献

Diminished survival due to hepatitis B has been observed after renal transplantation (RT). Lamivudine, a second-generation nucleoside analogue, has been approved for the treatment of chronic hepatitis B virus (HBV) infection in patients with normal renal function. Numerous clinical experiences with lamivudine after RT have been recently published. Despite numerous shortcomings, all of these reports have shown encouraging results. The rate of clearance of HBV viremia ranged between 67% and 100%, and the frequency of ALT normalization was between 50% and 100% with lamivudine use. Even patients with fibrosing cholestatic hepatitis, a serious form of HBV-related liver disease with ominous course, have been successfully treated with lamivudine. Lamivudine therapy significantly improved the survival of HBsAg positive renal allograft recipients. However, numerous issues concerning the treatment of hepatitis B after RT remain unclear: the optimal time to initiate lamivudine, the appropriate duration of antiviral therapy after RT, and the role for pre-transplantation liver biopsy. Also, the management of lamivudine resistance remains a concern for physicians. Clinical trials are under way. 相似文献

The histologic findings in the original liver obtained from 9 liver allograft patients with active B virus hepatitis were compared with 28 posttransplant pathology specimens. All specimens were studied with the use of light and immunohistochemical microscopy in conjunction with pertinent clinical data. Eight of the 9 patients had chronic active hepatitis B (HB) with cirrhosis, prior to transplant, one of which had coexistent hepatocellular carcinoma. The ninth patient had fulminant hepatic necrosis secondary to acute HB prior to transplantation. In all of the patients with chronic HB prior to transplantation who survived more than 2 months after transplantation recurrent infection of the graft developed despite perioperative HB immunoglobulin therapy. The patient with acute fulminant hepatitis B pretransplant has done well postoperatively and has evidence of HB virus immunity (positive anti-HBs) 15 months after transplantation. Examination of tissue specimens obtained during episodes of allograft dysfunction in these 9 patients indicate that pathologic alterations of active HB infection of the allograft are associated with a preferential lobular insult, whereas those occurring in rejection preferentially involve portal tract structures. Serologic data combined with biopsy histopathologic data are essential in distinguishing between the two quite different events. 相似文献

One hundred and six consecutive chronic hepatitis B virus (HBV) carriers were studied for the prevalence of delta markers in serum and tissue, and the clinical and histological features of those with and without delta infection were compared. Twenty (18.9%) patients were positive for anti-delta in serum or delta antigen in the liver or both. They presented at a younger age (30.3 v 38 years). All of them were symptomatic at the time of biopsy, in contrast to 35% of patients without delta infection who were not symptomatic. Those with delta infection had higher serum transaminase values and showed more severe liver damage on biopsy: chronic active hepatitis in 45% and cirrhosis in 55%. There was more pronounced disease activity both within the parenchyma and in the portal and periportal zones. The histological diagnosis of the 86 patients without delta infection included minimal disease (10%), chronic persistent hepatitis (9%), chronic active hepatitis (62%), and cirrhosis (19%). Delta infection in chronic HBV carriers is associated with a more active and progressive liver disease. 相似文献

Chronic hepatitis B surface antigen (HBsAg) carriers run a high risk of developing chronic liver disease after renal transplantation. To determine the impact of liver disease on long-term morbidity and mortality of HBsAg carriers following kidney transplantation we analyzed 1977 patients, including 76 HBsAg carriers, who underwent renal transplantation during the period 1968–1992. Although the HBsAg carriers had a better 5-year patient and graft survival rate (94% and 83%) than HBsAg-negative patients (87% and 61%), the prognosis was poor after the tenth year of transplantation. Transplant loss is more frequently caused by death of the HBsAg carriers, in contrast to the total population (34% vs 17% for HBsAg-negative patients). Death occurs in 73% of cases due to complications of hepatitis B. In the HBsAg-negative patients, the predominant cause of death is cardiovascular failure (51% vs 11% in HBsAg carriers), whereas only 2% died of liver disease. Kidney transplantation in HBsAg carriers with normal liver function appears to be justified because of rare graft loss due to acute rejection, low early morbidity and mortality, and late onset of fatal hepatic deterioration.Abbreviations HBsAg

背景:研究认为肾移植后感染肝炎病毒,比术前感染有更为严重的肝损害表现,且有观点认为术前肝炎病毒感染对肾移植术后5年内肾功能影响不大。
目的:分析肾移植后的重症肝炎发病情况和治疗方法。
方法:对19例肾移植后重症肝炎病例进行回顾性分析。治疗包括一般治疗、抗病毒治疗、免疫抑制剂方案调整和人工肝治疗。主要观察患者综合治疗后一般情况、肝功能、血常规及死亡率。
结果与结论:19例重症肝炎患者经过常规治疗和抗病毒治疗,部分应用胆红素吸附治疗,12例应用人工肝治疗患者,精神和神智均有不同程度的好转,胆红素和转氨酶均有一定程度的下降。死亡13例,其中术后感染肝炎病毒的4例全部死亡,3例单纯药物性肝损害患者全部痊愈。结果提示肾移植后重症肝炎死亡率高,对于诊断为重症肝炎患者常规治疗基础上,进行一定的抗病毒治疗和/或人工肝治疗,可使部分患者病情逆转,可能降低死亡率。 相似文献

BACKGROUND: Histopathologic features of early recurrent hepatitis C after orthotopic liver transplantation (OLTx) may be modified by immunosuppressive therapy or complicated by other conditions. Hepatitis C virus (HCV) RNA level usually increases after OLTx, but its correlation to histologic findings is not clear. OBJECTIVE: To evaluate the histologic findings of early recurrent hepatitis C in liver allografts and its correlation to serum HCV RNA level. METHODS: We studied 14 patients who underwent OLTx for chronic HCV infection. Thirty liver biopsy specimens and HCV RNA levels of 22 corresponding plasma samples obtained during the first 6 months following OLTx were analyzed. The control group (9 patients, 25 biopsy specimens) was chosen at random from patients with chronic liver disease other than HCV who were undergoing OLTx, and all tested negative for HCV RNA by polymerase chain reaction after OLTx. RESULTS: Statistically significant pathological features of early recurrent HCV infection were the number of acidophilic bodies, piecemeal necrosis, lymphocyte predominance in the portal tracts, and fibrous septum. These findings and histologic activity index scores increased with time after OLTx. The HCV RNA levels determined by branched DNA assay showed no significant correlation with histologic features. However, patients with higher histologic activity index scores tended to have higher RNA levels. CONCLUSIONS: Liver biopsy specimens are helpful for the diagnosis or confirmation of early recurrent hepatitis C in liver allografts, but serial biopsy specimens are sometimes required for definite diagnosis. The HCV RNA levels are usually higher in patients who display signs of more severe liver damage. 相似文献

We report a case of rapidly progressive chronic active hepatitis (CAH) following acute delta infection in a previously asymptomatic hepatitis B virus carrier. Serologic evidence of delta superinfection coincided with an acute icteric hepatitis, and was followed by the development of clinically evident chronic liver disease. The liver biopsy specimens documented the acute hepatitis and subsequent progression of severe CAH. This case illustrates the clinical and pathologic changes that may follow acute delta infection in chronic hepatitis B carriers. 相似文献
