Lung Transplantation for Cystic Fibrosis in Turkey: First Report.

Exp Clin Transplant 2021 Feb 17. Epub 2021 Feb 17.

From the Department of Thoracic Surgery, Kartal Kosuyolu Training and Research Hospital, Istanbul, Turkey.

Objectives: Lung transplant is the most important treatment approach that improves the life expectancy and quality of life for patients with cystic fibrosis with end-stage lung disease. In this study, we retros-pectively analyzed patients with cystic fibrosis who were referred to our lung transplant program in Turkey.

Materials And Methods: We evaluated 14 patients with cystic fibrosis who were referred to our lung transplant clinic between December 2016 and December 2019. The characteristics of the patients at the time of referral to our lung transplant clinic, survival, and lung transplant results were recorded.

Results: Four patients died on the wait list, 3 patients were not eligible for lung transplant, and lung transplant was performed in 7 patients. The mean age of all patients was 22.8 years (range, 11-41 years), and the mean age for patients who underwent lung transplant was 27.5 years (range, 21-41 years). The mean time of suitable donor offer or survival life was 140 days in the patients who were referred for lung transplant. The 1-year mortality rate was 28.6% (2 of 7 patients) after lung transplant. One patient died of chronic lung allograft dysfunction at the 25th month after lung transplant. Four patients were alive without any problems.

Conclusions: Lung transplant is the final treatment method for patients with cystic fibrosis with terminal period lung disease. To provide the best benefit, patients should be evaluated for transplant early. Cystic fibrosis care clinics and lung transplant clinics should work in coordination in order to increase the number of lung transplants and improve outcomes.

Lung transplantation for graft-versus-host disease after allogeneic stem cell transplantation: A report of two cases.

Turk Gogus Kalp Damar Cerrahisi Derg 2020 Jul 28;28(3):543-546. Epub 2020 Jul 28.

Allogeneic peripheral stem cell transplantation is an effective treatment of malignant and non-malignant hematological diseases. However, it is associated with several complications, such as graft-versus-host disease, and also various complications involving different organ systems. Late-onset non-infectious lung complication is one of them. This pathology may also affect the different anatomical regions in the lung as parenchymas, bronchi, or vessels and may manifest with different clinical presentations. Lung transplantation can be an effective treatment in patients with pulmonary complications after allogeneic stem cell transplantation and also in patients who do not respond to treatment adequately and with a limited life expectancy. Herein, we report two rare cases who underwent lung transplantation after allogeneic stem cell transplantation.

Extracorporeal membrane oxygenation as a bridge to lung transplantation in a Turkish lung transplantation program: our initial experience.

Lung transplantation is a life-saving treatment for patients with end-stage lung disease. Although the number of lung transplants has increased over the years, the number of available donor lungs has not increased at the same rate, leading to the death of transplant candidates on waiting lists. In this paper, we presented our initial experience with the use of extracorporeal membrane oxygenation (ECMO) as a bridge to lung transplantation. Between December 2016 and August 2018, we retrospectively reviewed the use of ECMO as a bridge to lung transplantation. Thirteen patients underwent preparative ECMO for bridging to lung transplantation, and seven patients successfully underwent bridging to lung transplantation. The average age of the patients was 45.7 years (range, 19-62 years). The ECMO support period lasted 3-55 days (mean, 18.7 days; median, 13 days). In seven patients, bridging to lung transplantation was performed successfully. The mean age of patients was 49.8 years (range 42-62). Bridging time was 3-55 days (mean, 19 days; median, 13 days). Two patients died in the early postoperative period. Five patients survived until discharge from the hospital. One-year survival was achieved in four patients. ECMO can be used safely for a long time to meet the physiological needs of critically ill patients. The use of ECMO as a bridge to lung transplantation is an acceptable treatment option to reduce the number of deaths on the waiting list. Despite the successful results achieved, this approach still involves risks and complications.

The effects of reactive hyperemia on stimulation of endothelium-derived nitric oxide in on-pump and off-pump coronary artery bypass surgeries.

Artif Organs 2011 Feb;35(2):131-6

Department of Cardiac Surgery, Kartal Kosuyolu Heart and Research Center, Istanbul, Turkey.

The purpose of this study is to compare the effects of cardiopulmonary bypass (CPB) on the endothelium-derived nitric oxide (NO) levels in on-pump and off-pump coronary artery bypass surgeries. Forty consecutive patients were divided randomly into two groups depending on use of CPB in coronary artery bypass graft surgery (group 1: n = 20, off-pump, and group 2: n = 20, on-pump). The plasma endothelium-derived NO levels were determined at baseline and after reactive hyperemia before and after surgery. Reactive hyperemia was induced by inflating a blood pressure cuff placed on the upper forearm, for 5 min at 250 mm Hg followed by a rapid deflation. Blood was collected at 1 min after cuff deflation from the radial artery on the same side. Preoperative use of all medications was recorded. The baseline plasma NO levels before operation were 17.10 ± 7.58 in group 1 and 15.49 ± 5.26 nmol/L in group 2. Before operation after reactive hyperemia, the plasma NO levels were 26.97 ± 11.49 in group 1 and 26.57 ± 12.87 nmol/L in group 2. Two hours after surgery, the plasma NO levels at baseline and after reactive hyperemia were not significantly different from each other (group 1: 18.03 ± 6.37 and group 2: 19.89 ± 9.83 nmol/L; group 1: 27.89 ± 18.36 and group 2: 39.13 ± 23.60 nmol/L, respectively; P > 0.05). A positive correlation was shown between preoperative nitroglycerine use and the postoperative plasma NO levels after reactive hyperemia (r = 0.51, P = 0.001). Linear regression analysis was performed (F = 4.10, R = 0.56, R(2)  = 0.32, P =  0.008) and the only independent parameter that had an effect on postoperative plasma NO levels after reactive hyperemia was found to be preoperative nitroglycerine use (t = 3.68, P = 0.001). Coronary artery bypass surgery with CPB does not have significant effect on plasma endothelial derived NO levels. The postoperative plasma NO levels after reactive hyperemia significantly correlated with preoperative nitroglycerine use.
