Background: Late-onset pulmonary complications can occur following hematological stem cell transplantation (HSCT). In allogeneic HSCT these complications are often associated with chronic graft-versus-host disease (GVHD). Lung transplantation (LTx) often remains the only viable therapeutic option in these patients.

Objectives: To describe our experience with LTx due to GVHD after HSCT and to compare the long-term survival of this group of patients to the overall survival of our cohort of LTx recipients for other indications.

Methods: We retrospectively retrieved all data on patients who had undergone LTx for end-stage lung disease as a sequela of allogeneic HSCT, between 1997 and 2021, at Rabin Medical Center in Israel.

Results: A total of 15 of 850 patients (1.7%) from our cohort of LTx recipients fulfilled the criteria of LTx as a sequela of late pulmonary complication after allogeneic HSCT. The median age at the time of HSCT was 33 years (median 15–53, range 3–60). The median time between HSCT and first signs of chronic pulmonary GVHD was 24 months (interquartile range [IQR] 12–80). The median time from HSCT to LTx was 96 months (IQR 63–120). Multivariate analysis showed that patients transplanted due to GVHD had similar survival compared to patients who were transplanted for other indications.

Conclusions: LTx for GVHD after allogeneic HSCT constitutes an important treatment strategy. The overall survival appears to be comparable to patients after LTx for other indications.

Background: Idiopathic pulmonary fibrosis (IPF) has poor prognosis. Anti-fibrotic treatment has been shown to slow disease progression. Lung transplantation (LTx) offers a survival benefit. The 5-year survival after LTx in IPF is between 40 and 50%

Objectives: To evaluate which IPF patients have better prognosis following LTx.

Methods: A retrospective study was conducted with all IPF patients who had undergone LTx in the Rabin Medical Center between 2010 and 2018. We collected data on pre-evaluation of pulmonary function tests, echocardiographic and right heart catherization, and anti-fibrotic treatments. The Kaplan-Meier method was used for survival analysis.

Results: Among148 patients who underwent LTx, 58 were double LTx (DLT) and 90 single LTx (SLT). Mean age was 58.07 ± 9.78 years; 104 males and 44 females. DLT patients had significantly lower survival rates than SLT in the short and medium term after LTx. Patients with saturation above 80% after the 6-minute walk test (6MWT) had higher survival rates. Patients over 65 years of age had a lower survival rates. Those with pulmonary hypertension (PHT) above 30 mmHg had a poorer prognosis with lower survival rates.

Conclusions: IPF patients with higher mean PHT, older age (> 65 years), and desaturation following 6MWT had lower survival rates following LTx. DLT may decrease survival rate compared to SLT just for the short and medium period of time after LTx. These results may lead to better selection of IPF patient candidates for LTx. Additional studies are warranted for choosing which patients will have better prognosis after LTx.

Background: Studies in lung transplantation demonstrate that the ancestry and gender dissimilarities of donor–recipients lead to a decrease in survival of the recipient. 

Objectives: To evaluate the survival of lung transplant recipients in Israel based on whether the donors and recipients are of Jewish or Arab ancestry as well as survival based on gender match or mismatch.

Methods: We performed a retrospective observational cohort study of 345 lung transplant recipients at the Rabin Medical Center, Petah Tikva, Israel between January 1997 and January 2013. We compared the survival of lung transplant recipients in two ancestry categories: ancestry matched (Jewish donors to Jewish recipients or Arab donors to Arab recipients) and ancestry mismatched (Jewish donors to Arab recipients and vice versa). We also compared the survival among the four gender donor and recipient combinations (male to male, female to female, male to female, and female to male). 

Results: Survival analysis revealed no significant differences between the two ancestry groups (P = 0.51) and among the four gender combinations (P = 0.58). On Cox multivariate analysis, younger donor age was the only significant parameter for longer survival (hazards ratio 1.025, 95% confidence interval 1.012–1.037).

Conclusions: Gender and ancestry mismatches in these two Israeli populations do not appear to alter the clinical outcomes following lung transplantation.

 Background: Lung transplantation is a well-established therapeutic option for end-stage lung disease in cystic fibrosis. Although it confers a clear survival advantage, outcome differs among centers according to local experience, patient selection, transplantation procedure, and postoperative care.

Objectives: To evaluate the national Israeli experience with lung transplantation in patients with CF[1].

Methods: We reviewed the medical charts of all CF patients who underwent lung transplantation between January 1996 and June 2005 at the two Israeli centers that performed this procedure.

Results: Eighteen transplantations were performed in 17 patients. Mean patient age at transplantation was 25.3 ± 9.1 years, and mean duration of follow-up in survivors (n=14) was 37.2 months (range 1–113 months). The actuarial survival rate was 88% at 1 year and 74% at 5 years. Pulmonary function, expressed as percent of predicted normal forced expiratory volume in 1 sec, improved from 22.4 ± 8.1% to 76 ± 16.8% at one year after transplantation. Bronchiolitis obliterans syndrome was diagnosed in 5 patients (29%), of whom 2 died and 2 are currently candidates for retransplantation. Median time to onset of BOS[2] was 34.2 months (range 17–64 months).

Conclusion: In Israel, the early and intermediate-term results of lung transplantation for cystic fibrosis are encouraging. BOS remains a major complication that threatens long-term outcome.

Background: Pulmonary disease is the most frequent cause of morbidity and mortality in cystc fibrosis patients. New techniques such as non-invasive positive pressure ventilation have resulted in prolongation of life expectancy in CF[1] patients with end-stage lung disease.

Objectives: To determine the role of NIPPV[2] in CF patients awaiting lung transplantation.

Methods: Between 1996 and 2001 nine CF patients (5 females) with end-stage lung disease were treated with bi-level positive airway pressure ventilation in the "spontaneous" mode.

Results: The patients' mean age at initiation of BiPAP[3] was 15 years (range 13–40 years) and the mean duration of BiPAP usage was 8 months (range 3–16 months). Four patients underwent successful lung transplantation, three patients died while awaiting transplantation, and the remaining two are still on NIPPV while waiting for transplantation. Patients' body mass index increased significantly (P < 0.05) during BiPAP therapy (from 16.1 to 17.2 kg/m2). Blood pH, paCO2, and bicarbonate improved significantly (from 7.31 to 7.38, 90.8 to 67.2 mmHg, and 48.9 to 40.3 mEq/L, respectively). Pulmonary function tests were not affected by BiPAP usage. The patients experienced a significant alleviation in morning headaches and improvement in quality of sleep (P < 0.003). There were no major complications during BiPAP usage.

Conclusions: We demonstrated that long-term NIPPV can stabilize and improve physiologic parameters such as ventilation, arterial blood gases and body mass index, as well as subjective symptoms such as sleep pattern, daily activity level, and morning headaches in CF patients with end-stage lung disease. Further prospectively controlled studies are needed to evaluate the potential of BiPAP therapy and its influence on morbidity and mortality in the post-lung transplantation period.

Background: Historically, donor age above 55 years has been considered to be a relative contraindication for organ transplantation. The shortage of organs for transplantation has led to the expansion of the donor pool by accepting older donors. 

Objectives: To compare the 1 year follow-up in patients after lung transplantation from older donors (>50 years old) and in patients after transplantation from younger donors (± 50 years).

Methods: The study group comprised all adult patients who underwent lung transplantation at the Rabin Medical Center between May 1997 and August 2001. Donors were classified into two groups according to their age: ≤ 50 years (n=20) and > 50 years (n=9). Survival, number and total days of hospitalization, development of bronchiolitis obliterans syndrome, and pulmonary function tests, were examined 1 year after transplantation.     

Results: We performed 29 lung transplantations in our center during the observed period. Donor age had no statistically significant impact on 1 year survival after lung transplantation. There was no statistically significant effect on lung function parameters, the incidence of hospitalization or the incidence of bronchiolitis obliterans between both donor age groups at 1 year after transplantation.

Conclusions: Donor age did not influence survival or important secondary end-points 1 year after lung transplantation. By liberalizing donor criteria of age up to 65 years, we can expand the donor pool, while assessing other possible mechanisms to increase donor availability.
