Demographic Differences Between Two 7-Year Periods of Organ Donation in Iran: A Single-Center Experience

Changes in Clinical Features and Demographics in Donors After Brain Death Over the Past 20 Years: A Single-Center Experience in the Republic of Korea

OBJECTIVES

We investigated clinical characteristics and demographics of brain death in patients from a single center in Korea to identify possible changes in organ procurement by comparing early and late periods.

MATERIALS AND METHODS

Potential donors diagnosed as brain dead and who had provided organ donation consent from May 2000 to May 2020 were considered. Donors were divided into 2 categories: early period (2000-2010) and late period (2011-2020).Demographic data, clinicalrisk factors, cause of death, use ofinotropic and vasoconstrictor agents, laboratory findings, intensive care unit stay data, loss of donors, and number of donated organs were analyzed.

RESULTS

Mean age of donors significantly increased in the late period (36.0 ± 12.0 vs 46.0 ± 15.1 years), but there were no significant differences in the proportion of females and the number of pediatric donors (<18 years). The number of donors who smoked decreased (61% vs 41%), but hypertension rate increased significantly in the late period (17.4% vs 31.0%). In the late period, fewer brain dead donors were lost (19.0% vs 7.59%) and use of vasoconstrictor agents was more frequent (25.3% vs 64.5%) than use of inotropic agents (73.1% vs 49.3%). In the late period, heart(19.0% vs 37.3%) and lung (0% vs 18.3%) procurement rates increased and the number of transplanted organs per donorincreased (2.58 ± 1.6 vs 3.14 ± 1.50; P = .016). Causes of death were primarily from head traumas (34.4%), cerebral aneurysms (21.7%), spontaneous intracerebral hemorrhage (21.3%), and asphyxia/hanging (16.3%). Head trauma decreased in the late period (46% vs 29.7%; P = .021) but still constituted the most common cause of death.

CONCLUSIONS

We found no definite demographic changes in brain dead donors. Donors with cerebrovascular disease increased annually, but trauma was still the most common cause of brain death, with suicides being highly frequent.

Lung transplant programs in developing countries: challenges, solutions, and outcomes

PURPOSE OF REVIEW

The majority of lung transplants (LT) performed are in developed countries. In contrast, little is known about the status of LT in developing nations. The objective is to summarize the challenges, present solutions, and review outcomes of LT in developing countries. We hope this review will guide healthcare providers in such countries that are contemplating embarking on this journey.

RECENT FINDINGS

The key challenges that programs in developing countries encountered included shortage and marginal quality of donated organs, lack of dedicated multi-disciplinary LT team, limited availability of advanced technology and high risk of post-transplant infections. Education and collaboration among government, public, and healthcare sectors was seen as fundamental to building and maintaining a successful program. Despite minimal resources and huge challenges, LT survival rates in developing countries improved and were comparable with outcomes reported by the International Society for Heart and Lung Transplantation (ISHLT) Registry.

SUMMARY

Starting a new LT program is a daunting task that is complex and resource intensive, especially in developing countries. Improving outcomes indeed provide impetus to continue to persevere in this endeavor with support from all sectors. The findings presented here could help new programs to better anticipate and tackle challenges.
