结核病是实体器官移植(SOT)术后严重而复杂的感染性疾病。SOT术后长期使用免疫抑制剂,使受者结核感染和结核病发生率升高。由于抗结核药物的肝肾毒性及其与免疫抑制剂之间药物代谢的相互干扰,导致临床诊断和抗结核治疗复杂性明显增加,病死率明显高于非移植结核病患者。SOT术后结核病的流行病学特点包括继发性肺结核、肺外结核和血行播散性肺结核发生率均高于普通人群。SOT术后结核病的临床诊断有其特殊性。由于免疫抑制剂的使用,结核相关的细胞免疫应答反应减弱,从而导致临床症状不典型和实验室检查敏感性降低。发热是其最常见的典型症状。病原学、细胞免疫学、影像学诊断应常规进行。SOT术后结核病的预防包括受者和捐献者评估,潜在结核杆菌感染供者与受者的治疗。严格掌握捐献者捐献和受者移植的适应证,排除活动性结核病。活动性结核病是器官移植和捐献的禁忌证。SOT术后活动性结核病的治疗比较困难,应尽可能在移植前诊断和治疗活动性结核病,筛查中区分移植受者潜伏性结核杆菌感染和无症状的活动性结核病常较困难,本文对移植后活动性结核病治疗的基本原则进行了具体的阐述。  相似文献

目的探讨乙型肝炎病毒(HBV)和(或)丙型肝炎病毒(hepatitis C virus,HCV)感染对肾移植受者长期存活的影响及预防措施。方法 HBV和(或)HCV感染肾移植受者110例(感染组),其中HBV感染受者56例、HCV感染受者52例,HBV与HCV合并感染2例。非HBV与非HCV感染受者694例(非感染组)。感染组受者术前有病毒复制者予积极治疗,研究早期肝功能正常者可接受肾移植,后期均用聚合酶链反应(PCR)检测,要求连续3~6个月HBV脱氧核糖核酸(DNA)0copy/ml,HCV核糖核酸(RNA)0copy/ml方可接受肾移植。术后定期检测HBV与HCV,定期检测感染组受者HBVDNA滴度、HCVRNA滴度。发现HBV复制,选用拉米夫定、阿德福韦酯治疗,酌情减少免疫抑制剂用量。分别比较两组术后1、3、5年人、肾存活率,比较两组的肝功能衰竭病死率。结果非感染组人、肾存活率分别为:1年94.2%、91.4%,3年为86.4%、85.2%,5年为82.7%、78.9%;感染组人、肾存活率分别为:1年90.2%、88.1%,3年为88.9%、86.2%,5年为81.5%、76.3%;两组数据比较差异均无统计学意义(均为P>0.05)。感染组中14例(12.7%)死于肝功能衰竭,其中10例为HBV感染者,非感染组受者无1例死于肝衰竭。感染组术后肝衰竭病死率明显高于非感染组(12.7%、0,P<0.05)。结论受者术前HBV和(或)HCV感染会明显增加肾移植术后肝衰竭死亡危险。患者术前处于病毒复制期应予积极治疗,在肝炎病毒停止复制6个月后再考虑肾移植。长期随访中应定期复查HBV与HCV感染指标,早确诊、早治疗,并及时调整免疫抑制剂剂量。  相似文献

BACKGROUND: Tuberculosis (TB) is an important infection encountered post-transplantation especially in developing countries, with high incidences of morbidity and mortality. In this report, we study the risk factors and impact of TB on the outcome of kidney transplantation. METHODS: Of 1200 live-donor Egyptian kidney transplantations, 45 (3.8%) patients developed post-transplant TB. Of these, five had had TB pre-transplantation and 40 were male. The mean age was 32.6 +/- 10.5 years. Primary immunosuppression treatment for 39 (86.7%) patients was cyclosporine (CsA). RESULTS: The mean time interval between transplantation and TB diagnosis was 49.8 +/- 41.5 (range 2-180) months. In 86.7% of patients, TB was diagnosed one year post-transplantation. Urinary TB was the most common form (53%), while pleuropulmonary TB accounted for 38%. All post-transplant TB patients received a triple anti-tuberculous therapy (rifampicin, ethambutol and INH) with a favorable response in all but two patients who needed another 24-month course. Hepatotoxicity was seen in 11 patients, eight were mild with normalization after temporary withdrawal of rifampicin, and three cases were severe, but mortality was not attributable to hepatocellular failure. Twelve patients died, 11 of them due to unrelated causes. Chronic rejection occurred in more than half of the patients (55.6%), of whom 24 (96%) were CsA-treated, which can be attributed to rifampicin/CsA interaction. More than 35% of TB patients lost their graft as a result. Pre-transplant tuberculosis patients had a comparable post-transplant course. CONCLUSIONS: TB is a common infection in renal transplant recipients with a peak incidence occurring one year post-transplant. Chronic rejection is a serious complication that had a negative impact on the graft survival, especially in CsA-treated recipients. INH prophylaxis is safe in pre-transplant TB. The post-transplantation outcome in the pre-transplant tuberculosis patients is no different from non-TB patients.  相似文献

Aboriginal populations experience a very high rate of end-stage renal disease (ESRD); however, little is known about the outcomes of transplantation in this population. We performed a retrospective database review to determine the short- and long-term outcomes of kidney transplantation in Aboriginals. Adult Aboriginal (AB) and Caucasian (C) individuals receiving primary kidney transplants between 1969 and 2003 in Manitoba, Canada were examined. A total of 705 recipients were included (126 AB and 579 C). AB recipients were younger, had different etiologies of ESRD, longer cold-ischemic times for deceased donor transplants, and higher peak panel reactive antibody levels. At 1 year post-transplant, there was no difference in serum creatinine, acute rejection or graft survival between AB and C recipients. However, AB recipients experienced greater weight gains early post-transplant and were more likely to develop post-transplant diabetes mellitus. AB recipients exhibited inferior 10-year graft (AB 26% vs. C 47%, p < 0.01) and patient survival (AB 50% vs. 75%, p < 0.01). When graft survival was censored for death with a functioning graft, there was no difference between the two groups. Multivariate analysis revealed AB race to be an independent predictor of premature graft failure and patient death. In conclusion, kidney transplant outcomes have historically been inferior in the Manitoba population of Canadian Aboriginals.  相似文献

BACKGROUND/AIMS: Lipid abnormalities present in the post-transplant period may contribute to the development and progression of complications leading to graft and patient loss. In the present study serum levels of antibodies against oxidised LDL (Ab-oxLDL) in kidney graft recipients were investigated along with their possible relation to the development of complications in the post-transplant period, and to the outcome of kidney transplantation. METHODS: Serum levels of Ab-oxLDL and lipid pattern were evaluated in 92 kidney graft recipients before and at 3, 6, 12, and 24 months after kidney transplantation, as well as in 90 healthy blood donors (control group). RESULTS: Kidney graft recipients had higher frequency of low levels of Ab-oxLDL as compared with the control group. A decrease in Ab-oxLDL levels was observed at 6 months post-transplant. Patients with early graft loss due to acute rejection had lower pre-transplant Ab-oxLDL levels (p < 0.05) as compared to patients with graft survival >3 months. CONCLUSIONS: It is suggested that decreased Ab-oxLDL levels found in kidney graft recipients may reflect impaired response to the products of lipid oxidation or increased consumption of Ab-oxLDL, and are associated with graft loss due to acute rejection.  相似文献

BACKGROUND: We previously defined an intermediate group of cadaver kidney transplant recipients who do not have immediate graft function (IGF), but do not have sufficient graft dysfunction to be classified as having delayed graft function (DGF). We showed that this group with slow graft function (SGF) had an increased risk of rejection and inferior long-term results vs. recipients with IGF. The aim of our current study was to determine risk factors for SGF, which have not been well defined (in contrast to risk factors for DGF). METHODS: Between January 1, 1984 and September 30, 1999, we performed 896 adult cadaver kidney transplants at the University of Minnesota. Recipients were analysed in three groups based on initial graft function: IGF [creatinine (Cr) < 3 mg/dL by post-operative day (POD) no. 5], SGF (Cr > 3 mg/dL on POD no. 5, but no need for dialysis), and DGF (need for dialysis in the first week post-transplant). A multivariate analysis looked specifically at risk factors for SGF, as compared with risk factors for DGF. Outcomes with regard to graft survival and acute rejection (AR) rates were determined for the three groups. RESULTS: Of the 896 recipients, 425 had IGF, 238 had SGF, and 233 had DGF. A multivariate analysis of risk factors for SGF showed donor age >50 yr (RR=3.3, p=0.0001) and kidney preservation time >24 h (RR=1.6, p=0.01) to be the most significant risk factors. A multivariate analysis of risk factors for DGF showed similar findings, although high panel-reactive antibodies (PRA) and donor Cr >1.7 mg/dL were also significant risk factors for DGF. Initial function of the graft significantly influenced the subsequent risk of AR: at 12 months post-transplant, the incidence of AR was 28% for those with IGF, 38% for those with SGF, and 44% for those with DGF (p=0.04 for SGF vs. DGF). Initial graft function also significantly influenced graft survival: the 5-yr death-censored graft survival rate was 89% for recipients with IGF, 72% for those with SGF, and 67% for those with DGF (p=0.01 for IGF vs. SGF; p=0.03 for SGF vs. DGF). CONCLUSIONS: SGF represents part of the spectrum of graft injury and post-transplant graft dysfunction. Risk factors for SGF are similar to those seen for DGF. Even mild to moderate graft dysfunction post-transplant can have a negative impact on long-term graft survival.  相似文献

Abstract: Objectives: To analyze the characteristics of tuberculosis (TB) in Southern Chinese renal transplant recipients, and summarize the corresponding experiences in diagnosis and management. Method: Retrospectively study 41 documented post‐transplant TB cases out of the 2333 patients who received kidney transplantation in the First Affiliated Hospital of Sun Yat‐sen University between Jan. 1991 and Apr. 2007. Results: TB in the post‐renal‐transplant population in Southern China displayed the following characteristics: (i) high incidence within a short time after transplantation, the median interval between renal transplantation and diagnosis of TB was 8 months (range: 1‐156 months) and 56.1% were diagnosed within the first year post‐transplant; (ii) high prevalence (51.2%) of extra‐pulmonary tuberculosis; (iii) high co‐infection rate (19.5%), pathogens included candida albicans, pseudomonas aeruginosa, staphylococcus aureus, Acinetobacter haemolyticus and cytomegalovirus; (iv) fever (82.9%), cough (56.1%) and sputum (39.0%) are the most common clinical manifestations; (v) purified protein derivative of tuberculin (PPD) skin test had little diagnostic value in this group with a negative result in all 41 cases; (vi) acute rejection (29.3%) and liver function damage (17.1%) were the main adverse effects of anti‐tuberculosis chemotherapy; (vii) mortality of patients with post‐transplant tuberculosis reached up to 22.0%. Conclusions: Chinese renal transplant recipients face a high risk of TB because of their immuno‐compromised state and epidemiological prevalence of the disease. Therefore, attention should be given to this differential diagnosis in clinical practice. Balancing the benefits and disadvantages of anti‐tuberculosis chemotherapy is of importance for this specific population.  相似文献

Abstract:  In this single-institution study, we compared outcomes in diabetic recipients of living donor (LD) kidney transplants that did vs. did not undergo a subsequent pancreas transplant. Of 307 diabetic recipients who underwent LD kidney transplants from January 1, 1995, through December 31, 2003, a total of 175 underwent a subsequent pancreas after kidney (PAK) transplant; 75 were deemed eligible (E) for, but did not receive (for personal or financial reasons), a PAK, and thus had a kidney transplant alone (KTA); and 57 deemed ineligible (I) for a PAK because of comorbidity also had just a KTA. We analyzed the three groups (PAK, KTA-E, KTA-I) for differences in patient characteristics, glycemic control, renal function, patient and kidney graft survival rates, and causes of death. Kidney graft survival rates (actuarial) were similar in the PAK vs. KTA-E groups at one, five, and 10 yr post-transplant: 98%, 82%, and 67% (PAK) vs. 100%, 84%, and 62% (KTA-E) (p = 0.9). The long-term (greater than four yr post-transplant) estimated glomerular filtration rate (GFR) was higher in the PAK than in the KTA-E group: 53 ± 20 mL/min (PAK) vs. 43 ± 16 mL/min (KTA-E) (p = 0.016). The patient survival rates were also similar for the PAK and KTA-E groups. We conclude that the subsequent transplant of a pancreas after an LD kidney transplant does not adversely affect patient or kidney graft survival rates; in fact, it is associated with better long-term kidney graft function.  相似文献

Between January 1 and June 30, 1983, immunosuppressive drugs were administered in 20 renal transplant recipients undergoing 23 rejection episodes and in 3 patients with renal failure secondary to systemic disease. Legionella pneumophila, serogroup 1, pneumonia was diagnosed on 12/26 (47%) occasions. In an attempt to decrease this high rate, a program of erythromycin prophylaxis was instituted for every new patient who received immunosuppressive chemotherapy until eradication of the organism from the water supply could be realized. From July 1, 1983 to April 30, 1984, erythromycin prophylaxis (1.5-3 g/day by mouth) was administered during 39 episodes of high-dose immunosuppression (20 kidney graft recipients and 4 patients with systemic diseases); no cases of Legionnaire's disease were recorded. During the same period, erythromycin prophylaxis was withheld from 9 other high-dose immunosuppression episodes (7 kidney graft recipients and one patient with sarcoidosis); 5 cases of Legionnaire's disease occurred (56%) in this group. We conclude that erythromycin effectively protects immunocompromised patients in an environment contaminated with L pneumophila.  相似文献

Pre-donation kidney volume and function may be crucial factors in determining graft outcomes in kidney transplant recipients. We measured living donor kidney volumes by 3D helical computed tomography scanning and glomerular filtration rate (GFR) by (125)I-iothalamate clearances in 119 donors, and correlated these values with graft function and incidence of acute rejection at 2 years post-transplantation. Kidney volume strongly correlated with GFR (Pearson r= 0.71, p < 0.001). Body size and male gender were independent correlates of larger kidney volumes, and body size and age were predictors of kidney function. The effects of transplanted kidney volume on graft outcome were studied in 104 donor-recipient pairs. A transplanted kidney volume greater than 120 cc/1.73 m(2) was independently associated with better estimated GFR at 2 years post-transplant when compared to recipients of lower transplanted kidney volumes (64 +/- 19 vs. 48 +/- 14 mL/min/1.73 m(2), p < 0.001). Moreover, recipients of lower volumes had a higher incidence of acute cellular rejection (16% vs. 3.7%, p = 0.046). In conclusion, kidney volume strongly correlates with function in living kidney donors and is an independent determinant of post-transplant graft outcome. The findings suggest that (1) transplantation of larger kidneys confers an outcome advantage and (2) larger kidneys should be preferred when selecting from otherwise similar living donors.  相似文献
