Lung transplantation is the only successful treatment option for patients experiencing end-stage lung disease. Results have improved significantly in the last decade; however, the number one limiting ...factor is still the shortage of donor lungs. Due to the discrepancy between available donor lungs and patients awaiting lung transplantation, many centers have reintroduced donation after cardiac death (DCD). According to their results, DCD and donation after brain death (DBD) are comparable in terms of survival and graft function.
Currently in Hungary, donation is only allowed from DBD donors; however, due to the Eurotransplant agreement, non-heart-beating donation (NHBD) organs can be transplanted into Hungarian patients, and in some cases Hungarian transplant teams can also take part in NHBDs within the Eurotransplant region.
The Hungarian experience. A Hungarian patient received a lung from a 15-year-old uncontrolled DCD in Vienna. The donor was reanimated for 54 minutes and after lung procurement the lungs were put on ex vivo lung perfusion and later successfully implanted into the Hungarian recipient. The recovery was very successful and the patient is still alive.
The Hungarian Lung Transplantation Team was involved in a controlled Maastricht III donation in 2017. A 49-year-old female donor was reported from Ghent, Belgium. A multiorgan donation was carried out with 15 minutes of warm ischemic time in the case of the lungs.
DCD is an effective, safe, and available method to increase the donor pool. In the case of controlled donations, the necessary protocols have already been prepared. Although DBD is working very successfully in Hungary, infrastructural developments, education of professionals, and social preparations are all needed to implement a DCD protocol in Hungary.
After its initial difficulties were overcome, lung transplantation became an accepted and effective treatment for end-stage lung disease. Patients can take part in almost all kinds of sports after ...lung transplantation, including high-altitude mountaineering, which is an extreme sport even for healthy individuals. Several articles have been published about high-altitude tolerance of transplanted patients. However, this was the first high-altitude expedition that included only lung transplant patients.
The Vienna lung transplantation team organized an expedition in 2017 to conquer the peak of Mount Kilimanjaro, which consisted of 10 lung transplanted patients and 24 accompanying medical personnel. The participants were tested before and several times during the hike to evaluate their general and cardiopulmonary status, the severity of altitude sickness, and radio-morphologic changes. The results of the lung transplanted patients were compared to the results of their healthy companions.
The group started at 2360 meters and reached the 5895-meter-high summit of Mount Kilimanjaro after 6 days on June 18, 2017. Eight transplant patients and 24 escorting medical personnel reached the peak. This means that the success rate was 94%, which is significantly higher than the reported 85% for this route. The 2 transplant patients who did not make the summit turned back on the first and second day because they lacked the necessary fitness for the trip. We did not see a significant difference in the results regarding cardiopulmonary status or the severity of altitude sickness, although we observed mildly higher blood pressure and altitude sickness score results in the lung transplant group.
Based on our experiences, we can state that a stable patient after lung transplantation who attains the necessary physical fitness can achieve similar or even better physical results than an average healthy individual.
