ABSTRACT
Objective To evaluate the effect of donor age on short-term survival of patients with idiopathic pulmonary fibrosis (IPF) after lung transplantation. Methods Clinical data of 235 IPF donors and recipients of lung transplantation were retrospectively analyzed. Univariate and multivariate Cox proportional hazard regression models were employed to analyze the correlation between donor age and short-term mortality rate of IPF patients after lung transplantation. Kaplan-Meier was used to draw the survival curve. Results Univariate Cox regression analysis showed that donor age was correlated with the 1-year fatality of IPF patients after lung transplantation. The 1-year fatality of recipients after lung transplantation was increased by 0.020 times if donor age was increased by 1 year (P=0.009). Oxygenation index of the donors, preoperative oxygenation index, preoperative lung allocation score, preoperative N-terminal pro brain natriuretic peptide, pattern of transplantation, pattern of intraoperative extracorporeal membrane oxygenation and intraoperative blood transfusion volume of the recipients were correlated with 1-year fatality after lung transplantation (all P < 0.1). Multivariate Cox regression analysis demonstrated that there was no correlation between donor age and 30-, 90-, 180-d and 1-year fatality of IPF patients after lung transplantation (all P > 0.05). Sensitivity analysis showed that there was no significant difference in 30-, 90-, 180-d and 1-year fatality after lung transplantation among donors aged < 18, 18-33, 34-49 and ≥50 years (all P > 0.05). Conclusions Donor age exerts no effect upon short-term survival of IPF patients after lung transplantation. Considering the mechanical ventilation time, oxygenation index, infection and other factors of donors, the age range of lung transplant donors may be expanded.
ABSTRACT
During the novel coronavirus pneumonia (COVID-19) pandemic from 2020 to 2021, lung transplantation entered a new stage of development worldwide. Globally, more than 70 000 cases of lung transplantation have been reported to the International Society for Heart and Lung Transplantation (ISHLT). With the development of medical techniques over time, the characteristics of lung transplant donors and recipients and the indications of pediatric lung transplantation recipients have undergone significant changes. Application of lung transplantation in the treatment of COVID-19-related acute respiratory distress syndrome (ARDS) has also captivated worldwide attention. Along with persistent development of lung transplantation, it will be integrated with more novel techniques to make breakthroughs in the fields of artificial lung and xenotransplantation. In this article, research progresses on the characteristics of lung transplant donors and recipients around the world were reviewed and the development trend was predicted, enabling patients with end-stage lung disease to obtain more benefits from the development of lung transplantation technique.
ABSTRACT
Lung transplantation is an efficacious treatment for end-stage lung diseases in children. Shortage of donor lungs, poor donor-recipient matching, difficult postoperative management, multiple postoperative complications and high fatality jointly restrict the development of pediatric lung transplantation. However, significant progress has been achieved in each transplantation center along with the popularization of organ donation after citizen' s death, advancement of medical science and technology and accumulation of lung transplantation experience. In recent years, clinical application of donor lung from donation after brain death and marginal donor lung repair, maturity of perioperative life support technology and surgical transplantation procedure and reference of management experience after adult lung transplantation have accelerated rapid development of pediatric lung transplantation. In this article, current status and progress on primary diseases, utilization and allocation of donor lungs, selection of surgical techniques, management of postoperative complications and clinical prognosis of pediatric lung transplantation were elucidated, aiming to provide reference for clinical diagnosis and treatment.
ABSTRACT
Lung transplantation has been advanced for nearly half a century around the globe, and it has been developed rapidly for over 20 years in China. The field of lung transplantation in China has been gradually integrated into the international community. The outbreak of novel coronavirus pneumonia (COVID-19) in 2020 brought big challenges, as well as diverted the worldwide attention to the development of lung transplantation in China, accelerating international communication and cooperation. With the steadily deepening of clinical and basic research on lung transplantation for severe cases of COVID-19, organ transplant physicians have deepened the understanding and thinking of the maintenance of donors, selection of elderly and pediatric candidates, and perioperative management of recipients, as the future perspective of lung transplantation in China. For interdisciplinary research related to lung transplantation, it is necessary to carry out multi-center clinical trials with qualified study design and constantly promote the theoretic and practical innovation.
ABSTRACT
Objective To improve the surgical efficacy of bilateral lung transplantation for pediatric cystic fibrosis through multi-disciplinary team (MDT). Methods Preoperative MDT consultation was delivered for a 10-year-old child with rare end-stage cystic fibrosis to establish the corresponding treatment protocol. Results The child was diagnosed with cystic fibrosis for 5 years, and the indication of lung transplantation were confirmed. After preoperative MDT consultation, bilateral lung transplantation via a Clam-shell incision was determined. The vital signs were maintained stable during operation. Postoperatively, ventilator-assisted ventilation, anti-infection, immunosuppression, acid suppression, prevention of stress ulceration and other treatments were delivered. Individualized treatment was given according to the characteristics of the child, and the child was well recovered. Conclusions Through preoperative MDT consultation, lung transplantation yields satisfactory surgical efficacy in treating pediatric cystic fibrosis and lowers the risk of postoperative complications, which deserves application in clinical practice.
