In cystic fibrosis (CF) patients with end-stage pulmonary disease, lung transplantation (LTx) remains a life-extending therapy with good outcome in most patients. Despite early concern about chronic pretransplantation infections in the context of posttransplantation immunosuppression, typical CF-associated organisms such as Pseudomonas aeruginosa turned out to be quite well manageable and associated with favorable outcomes in transplanted CF patients, even in patients with highly resistant strains. However, the situation is less evident with other pathogens.
Burkholderia cenocepacia is associated with reduced survival and regarded as a contraindication for LTx in most centers, other Burkholderia species are less problematic. Other resistant Gram-negative bacteria and methicillin-resistant staphylococcus aureus in CF patients are not regarded as a contraindication. Nontuberculous mycobacteria disease in CF patients does not preclude successful recovery after LTx, although postoperative complications can be expected in patients with Mycobacterium abscessus and specific management is indicated. Fungal species should be treated aggressively to limit morbidity after transplantation.
Despite its complexity, LTx is safe in most CF patients, with good outcomes if the pathogens that are present are identified and adequately treated.
在患有终末期肺部疾病的囊性纤维化(CF)患者中,肺移植(LTx)仍然是一种延长生命的治疗方法,大多数患者预后良好。尽管早期担心在移植后免疫抑制背景下的慢性移植前感染,但事实证明,典型的CF相关病原体,如铜绿假单胞菌,在移植的CF患者中相当易于管理,并且与良好的预后相关,即使是在具有高度耐药菌株的患者中也是如此。然而,对于其他病原体,情况则不太明确。
洋葱伯克霍尔德菌与生存率降低相关,在大多数中心被视为LTx的禁忌证,其他伯克霍尔德菌属则问题较小。CF患者中的其他耐药革兰氏阴性菌和耐甲氧西林金黄色葡萄球菌不被视为禁忌证。CF患者的非结核分枝杆菌病并不排除LTx后成功康复,尽管脓肿分枝杆菌患者术后可能会出现并发症,需要进行特殊管理。应积极治疗真菌种类,以限制移植后的发病率。
尽管LTx很复杂,但在大多数CF患者中是安全的,如果识别出存在的病原体并进行充分治疗,预后良好。
