Landmarks in clinical solid organ transplantation in Vietnam.

Renal transplantation was first performed in Vietnam in 1992. Up to the end of 2010, there have been 400 kidney and 16 liver transplantations from related and unrelated living donors. From 8 brain-dead donors between 2008 and 2010, we performed 15 kidney, 1 liver, and 1 heart transplantation. Few people agree to donate their own or their relatives' after death, mainly owing to the traditional belief of the Vietnamese that "as a man lives, so shall he die." The demand for organs for transplantation therefore exceeds the organ availability. This article sought to present some achievements and challenges in the field of solid organ transplantation in Vietnam as well as the necessary measures to develop this young promising specialty.

Pancreas preservation for pancreas and islet transplantation: a minireview.

Pancreas preservation by cold storage using University of Wisconsin solution was the mainstay method used for pancreas transplantation during the past 2 decades. Other solutions, such as HTK, Celsior, and SCOT 15, could not demonstrate any advantage for short preservation periods. But the advent of clinical islet transplantation and the larger use of controlled non-heart-beating donors have prompted the transplantation community to develop methods for increasing pancreas graft quality while preventing ischemic reperfusion damages. Oxygenation by 1- or 2-layer methods during pancreas preservation, as well as the use of perfluorocarbons, might increase the islet yield. Based on the former methods, there is a renewed interest in machine perfusion and oxygenation in pancreas preservation for pancreas transplantation and islet preparation.

Contribution of donors after cardiac death to the deceased donor pool: 2002 to 2009 University of Liege experience.

OBJECTIVE: In this study, we have evaluated the organ procurement and transplantation activity from donors after cardiac death (DCD) at our institution over an 8-year period. Our aim was to determine whether this program influenced transplantation programs, or donation after brain death (DBD) activity. METHODS: We prospectively collected our procurement and transplantation statistics in a database for retrospective review. RESULTS: We observed an increasing trend in potential and actual DCD number. The mean conversion rate turning potential into effective donors was 58.1%. DCD accounted for 16.6% of the deceased donor (DD) pool over 8 years. The mean age for effective DCD donors was 53.9 years (range, 3-79). Among the effective donors, 63.3% (n = 31) came from the transplant center and 36.7% (n = 18) were referred from collaborative hospitals. All donors were Maastricht III category. The number of kidney and liver transplants using DCD sources tended to increase. DCD kidney transplants represented 10.8% of the DD kidney pool and DCD liver transplants made up 13.9% of the DD liver pool over 8 years. The DBD program activity increased in the same time period. In 2009, 17 DCD and 33 DBD procurements were performed in a region with a little >1 million inhabitants. CONCLUSION: The establishment of a DCD program in our institution enlarged the donor pool and did not compromise the development of the DBD program. In our experience, DCD are a valuable source for abdominal organ transplantation.

Renal transplantation from living related donors: a single center experience in Viet Nam.

INTRODUCTION: End-stage renal disease is a major public health problem in Viet Nam. A cooperative project between the University of Liège, Belgium, and the University of Medicine Pham Ngoc Thach, Ho Chi Minh City, Viet Nam, has permitted the establishment of an autonomous program of renal transplantation from living-related donors at the Peoples' Hospital No 115. The aim of this paper was to report the primary results of the project and to draw conclusions for the future. PATIENTS AND METHODS: From January 2004 to July 2008, we performed 33 living-related renal transplantations. Mean ages of donors and recipients were 31.8 ± 9.5 and 41.6 ± 13.5 years, respectively. Laparoscopic nephrectomy was performed in 6 donors. The immunosuppressive regimen consisted of three drugs associated with induction therapy using anti-interleukin-2 receptor monoclonal antibody. RESULTS: The 33 donors are in good health at follow-up. Four developed major intra- or postoperative hemorrhage necessitating transfusion, with a surgical re-exploration in 1 donor. Wound infection occurred in 2 donors. Posttransplant recipient and graft survivals at 1 versus 3 years were 82% and 73% versus 82% and 65%, respectively. Eight recipients presented 13 biopsy-proven acute rejection episodes that were reversible in 7, but 1 patient lost his graft due to an irreversible rejection. Two recipients developed cancer. CONCLUSIONS: These initial results have encouraged us to continue the program of renal transplantation from living-related donors. However, they also pointed out the need to develop other donor sources.

Results of kidney transplantation from donors after cardiac death.

Confronting the organ donor shortage, many transplant centers around the world increasingly use donors after cardiac death (DCD). Over the past 20 years, follow-up studies in kidney recipients comparing DCD and donors after brain death (DBD) have shown comparable long-term graft function and survival. As a consequence, DCD programs should be continued and expanded, for these donors constitute a potential solution to the imbalance between the numbers of end-stage kidney disease patients on waiting lists versus available kidney grafts. DCD kidneys do not necessarily signify suboptimal grafts; they may merit to be allocated the same as DBD grafts.
