BACKGROUND: FK 506 inhalant was recently developed for localized administration. We investigated its effects on acute lung allograft rejection and compared its efficacy with that of intramuscular administration of FK 506. METHODS: Rats (n = 123) with orthotopic left lung transplantation were divided into 9 groups. Six groups inhaled FK 506 (5 puffs, 10 puffs or 20 puffs per day), or were given intramuscular administration of FK 506 (0.05, 0.1 or 1.0 mg/kg/day). The other groups included rats receiving an isograft, rats with an untreated allograft, and a placebo group. All groups (n = 6 each) were monitored for 14 days post-operatively as an end-point and graft survival time was determined. The remaining animals were killed 4 days after transplantation. The histologic grade of rejection was determined for all groups (n = 6 each). With both (n = 3 each) inhalation therapy and intramuscular administration of FK 506, which showed similar degrees of effectiveness, both blood FK 506 concentration and cytokine expression in the graft and spleen were evaluated. RESULTS: FK 506 inhalation therapy extended allograft survival time and reduced histologic rejection on Day 4 in all groups. Graft survival time and histologic rejection scores at a dose of 10 puffs/day were comparable to those with 0.1 mg/kg/day of intramuscular FK 506. Trough concentrations of FK 506 in blood were detectable with 0.1 mg/kg/day of intramuscular FK 506, but not with 10 puffs/day. The messenger RNA expression levels of interferon-gamma in the lung allograft was suppressed significantly at a dose of 10 puffs/day. CONCLUSIONS: FK 506 inhalant enhances acute lung allograft survival with lower blood concentrations than when using comparable intramuscular administration.  相似文献

Background : We clinically and pathologically analyzed renal allografts from 19 renal transplant patients treated with tacrolimus (FK506) for more than 1 year.
Methods : Twenty-six renal allograft biopsy specimens from 19 renal transplant patients who underwent transplantations between 1991 and 1 993 were evaluated. Thirteen biopsies were performed from stable functioning renal allografts with informed consent (nonepisode biopsy) and the other 13 were from dysfunctional renal allografts with a clinical indication for biopsy (episode biopsy).
Results : The main pathologic diagnoses (some overlap) were acute rejection (AR; n = 4), chronic rejection (CR;n = 5), AR + CR(n=4), recurrent IgA nephropathy (n = 5), normal findings (n = 2), minimal-type chronic FK506 nephropathy (n = 9), and mild-type FK506 nephropathy (n = 11). Of the nonepisode biopsies, 7 and 4 biopsies showed minimal-type and mild-type chronic FK506 nephropathy, respectively. Chronic FK506 nephropathy consisted of rough and foamy tubular vacuolization (5 biopsies), arteriolopathy (angio-degeneration of the arteriolar wall; 20 biopsies), focal segmental glomerulosclerosis (4 biopsies) and the striped form of interstitial fibrosis (11 biopsies). The serum creatinine levels of patients in the mild-type chronic FK506 nephropathy group, which included 7 episode biopsies, were statistically higher than those in the minimum-type chronic FK506-nephropathy group (P < 0.001).
Conclusions : This study demonstrates that chronic FK506 nephropathy consists primarily of arteriolopathy manifesting as insudative hyalinosis of the arteriolar wall, and suggests that mild-type chronic FK506 nephropathy is a condition which may lead to deterioration of renal allograft function.  相似文献

肝胰肾联合移植的免疫抑制治疗   总被引:1,自引:0,他引:1  
目的 介绍1例存活超过1年的肝胰肾联合移植患者术后免疫抑制治疗方法。方法对1例肝炎后肝硬化合并尿毒症、I型糖尿病、慢性胰腺炎患者施行原位背驮式肝、胰液空肠引流式胰、十二指肠及肾一期联合移植,采用二剂巴利昔单抗(舒莱)诱导,抗胸腺细胞球蛋白(ATG)、他克莫司(FK506)、吗替麦考酚酯(MMF)、泼尼松四联维持治疗。结果 术后移植肝脏及胰腺功能1周内逐渐恢复;肾功能延迟恢复,于术后第16天因消化道大出血致肾脏血流下降,切除移植肾脏,于原移植部位进行第2次肾移植,术后第3天肾功能恢复正常,未发生排斥反应。患者已健康存活超过1年,移植肝、胰、肾功能良好,生活自理。结论 肝胰肾联合移植术前后采用二剂舒莱诱导,同时用ATG、FK506、MMF及泼尼松作为免疫维持治疗安全有效,用药期间进行移植物功能、血药浓度及T细胞亚群(CD4^+,CD4^+)监测是防治排斥反应、感染及药物中毒的有效手段。  相似文献

Abstract All renal allograft recipients ( n = 32) in Sweden and Norway who were converted from cy-closporin(CyA)-based immunosuppression to FK 506 (tacrolimus) between October 1992 and June 1995 were analyzed retrospectively. The reasons for conversion were acute refractory rejection ( n = 21), chronic rejection ( n = 4), and suspected CyA toxicity ( n = 6); one patient was converted for psychological reasons. The mean time from transplantation to conversion was 29 (range 1–243) weeks and there was a mean follow-up of 46 (2–143) weeks. Overall graft survival was 59 %, with graft survival 52 % in patients converted because of acute rejection, 50 % in patients converted because of chronic rejection, and 83 % in patients converted because of CyA toxicity. There was no significant correlation between preconversion serum creatinine and outcome. Seventy-two percent of the patients had significant side effects during FK 506 treatment, the most frequent ones being neurological and gastrointestinal symptoms. These improved after dose reduction. Two patients became overimmunosup-pressed and developed lymphoma. One patient died of the primary kidney disease, hemolytic uraemic syndrome. We conclude that FK 506 therapy is able to salvage kidneys with acute refractory rejection and that it is an alternative in patients with CyA toxicity. However, the risk of overimmunosuppression must be considered.  相似文献

Calcineurin inhibitors such as cyclosporine (CsA) and tacrolimus (FK506) show similar efficacy to prevent rejection within the first year after organ transplantation. However, their use is limited by side effects, such as kidney damage, hypertension, new-onset diabetes, and hyperlipidemia. The consensus opinion suggests that compared with CsA, FK506 has fewer negative effects on blood pressure, serum lipids, and renal function. Nevertheless, FK506 use is associated with a higher incidence of posttransplantation diabetes mellitus. FTY720 is a new compound that has shown beneficial effects in animal models of rejection in transplantation, ischemia/reperfusion injury, autoimmune diseases, and tumor development. Our aim was to investigate whether FTY720 + tacrolimus association could provide additional immunosuppression without causing renal toxicity. FTY720 as a monotherapy or in association with FK506 was administered to C57BL/6 mice for 21 days to prevent skin graft rejection and to evaluate renal function and structure. Increased skin allograft survival in the FTY720 + FK506 group was associated with decreased cell numbers in the spleen, blood, and axillary lymph nodes. Changes in major histocompatibility complex (MHC) class II and intercellular adhesion molecule-1 (ICAM-1) expressions in splenocytes were also found in this group. The major effects already described for FK506 (diabetes) or FTY720 (lymphopenia) were observed after 21 days administration even when the drugs were associated. FTY720 associated with FK506 caused fewer changes in kidney structure, and blood glucose levels were lower than in FK506 monotherapy.  相似文献
