Cultural barriers to kidney transplantation: a new frontier

Hemodialysis Patients' Willingness to Undergo Kidney Transplantation: An Observational Study

BACKGROUND

The number of dialysis patients is increasing, with only 20% undergoing kidney transplantation. In Saudi Arabia, no studies had examined transplantation barriers from the patients' perspectives. We aimed in this study to estimate hemodialysis (HD) patients' willingness to undergo kidney transplantation and to explore its underlying determinants.

METHODS

In an observational cross-sectional study involving adult HD patients from King Abdulaziz Medical City and King Abdullah Dialysis Center-Jeddah, patients were interviewed through a pre-tested questionnaire. Calculated sample size was 243.

RESULTS

Among the 252 HD patients (mean age, 55 years [standard deviation = 15.21]; 59% men; median duration on HD, 24 months [interquartile range, 11.1, 60]), 61% described their knowledge about kidney transplantation as "poor" or "very poor." Only 69% chose "willingness to undergo kidney transplantation" (proportion, 0.69; 95% confidence interval [CI], 0.64-0.75). The main reported reasons against willingness were being too old for transplantation (61%) and fear of surgical complications (26%). Less willingness was shown with age ≥60 years (adjusted odds ratio [AOR], 0.2; 95% CI, 0.11-0.36; P < .001), duration on HD ≥5 years (AOR, 0.47; 95% CI, 0.25-0.89; P = .021), and being non-married (AOR, 0.47; 95% CI, 0.24-0.93; P = .03).

CONCLUSIONS

Approximately one third of the respondents did not choose "willingness to undergo kidney transplantation." Willingness was negatively associated with older age, lack of spouse, and longer duration on HD. The majority of HD patients reported poor knowledge about kidney transplantation. Therefore, structured education may optimize the knowledge, perceptions, and attitudes of HD patients toward kidney transplantation and hence improve their transplantation willingness.

The prohibition of kidney sales and organ markets should remain

PURPOSE OF REVIEW

There is an ongoing vigorous debate regarding the wisdom of the current prohibition of organ sales in the United States. We argue that this prohibition must remain in place. We discuss the current international realities regarding organ vending in order to show that even a so-called 'regulated' market brings with it danger to the welfare of transplant donors, their recipients, and potential recipients of nonrenal organs. We counter the specific arguments made in favor of organ sales while recommending multiple measures that can serve to remove disincentives to noncommercial organ donation. We encourage the investment in innovative healthy transplant practice for the benefit of all.

RECENT FINDINGS

In 'natural experiments' performed in developing countries the outcome for kidney vendors, in terms of both their medical and psychosocial health, has been shown to be poor. A high incidence of serious infections has been reported in recipients of vended organs.

SUMMARY

Commercialization of living kidney donation does not serve the interests of the donors, endangers the health of recipients, and undermines the healthy development of the international transplant endeavor.

Kidney donation after cardiac death

There is continuing disparity between demand for and supply of kidneys for transplantation. This review describes the current state of kidney donation after cardiac death (DCD) and provides recommendations for a way forward. The conversion rate for potential DCD donors varies from 40%-80%. Compared to controlled DCD, uncontrolled DCD is more labour intensive, has a lower conversion rate and a higher discard rate. The super-rapid laparotomy technique involving direct aortic cannulation is preferred over in situ perfusion in controlled DCD donation and is associated with lower kidney discard rates, shorter warm ischaemia times and higher graft survival rates. DCD kidneys showed a 5.73-fold increase in the incidence of delayed graft function (DGF) and a higher primary non function rate compared to donation after brain death kidneys, but the long term graft function is equivalent between the two. The cold ischaemia time is a controllable factor that significantly influences the outcome of allografts, for example, limiting it to < 12 h markedly reduces DGF. DCD kidneys from donors < 50 function like standard criteria kidneys and should be viewed as such. As the majority of DCD kidneys are from controlled donation, incorporation of uncontrolled donation will expand the donor pool. Efforts to maximise the supply of kidneys from DCD include: implementing organ recovery from emergency department setting; improving family consent rate; utilising technological developments to optimise organs either prior to recovery from donors or during storage; improving organ allocation to ensure best utility; and improving viability testing to reduce primary non function.

The socioeconomic status of donors and recipients of living unrelated renal transplants in the United States

PURPOSE

We evaluated unrelated living kidney donation in the United States and examined the characteristics of unrelated donor-recipient pairs.

MATERIALS AND METHODS

We accessed United Network for Organ Sharing files to identify adult living donor renal transplant recipients who received a transplant between 1997 and 2007. We evaluated factors associated with unrelated donation and compared a composite index of the socioeconomic characteristics of donor and recipient ZIP Codes between living unrelated and living related renal transplantation pairs. Spousal pairs were categorized as living related.

RESULTS

Of 39,168 adult renal transplant recipients 19% underwent living unrelated renal transplantation. These recipients were more likely white (vs black, Hispanic and other race OR 0.77-0.82, p <0.05) and more highly educated (college vs less than high school OR 0.66, 95% CI 0.54-0.77), and more commonly received care at high volume transplant centers (vs lowest volume centers OR 0.89, 95% CI 0.82-0.95). Living unrelated renal transplantation recipients and donors lived in higher socioeconomic status index ZIP Codes than living related recipients (mean ± SD recipients and donors 0.62 ± 3.74 and 0.44 ± 3.63 vs 0.03 ± 3.85 and 0.10 ± 3.87, respectively, each p <0.001).

CONCLUSIONS

Living unrelated renal transplantation donors and recipients are generally of higher socioeconomic status than their living related renal transplantation counterparts. There is restricted access to unrelated donors among underserved populations.

Sociological and ethical issues in transplant commercialism

PURPOSE OF REVIEW

'Global transplant commercialism' (practices and policies involving international trade in organs from living vendors, e.g., 'transplant tourism') is currently subjected to unprecedented criticism. In parallel, the debate around 'local transplant commercialism' (practices and policies that confine trade in organs from living vendors to national markets or economic unions) is heating up. In an attempt to assess the potential outcomes of these trends, this article reviews and discusses some sociological and ethical issues, ending with a proposal for a reinvigorated anticommercialist strategy.

RECENT FINDINGS

The current international campaign against global transplant commercialism is conducted by an ad hoc alliance between strange bedfellows, proponents of local transplant commercialism on the one hand and opponents of any transplant commercialism on the other. Disparities in the rigor of the respective ethical discourses, the expanding list of precedents of legitimized commerce in the human body, and the political economy of transplantation, all suggest that the former have the upper hand.

SUMMARY

Recent achievements in the struggle against international organ trafficking may not herald the abolition of transplant commercialism but rather presage its reconfiguration in deglobalized forms. In light of such a prospect, those who wish to prevent the pervasive commodification of the human body from entering the gates of transplant medicine should consider devising a new, perhaps more radical, strategy.

Exploring Transplant Opportunities in Hmong Culture: A Case Report

A clinical case is used to explore the ethical complexities of solid organ donation and transplantation within the Hmong community in the United States. Although many cultures can present various ethical issues, the challenges of the Hmong belief system are unique and distinctly complex. Ways for the medical team to integrate with the Hmong value system to attempt to create an environment of transcultural respect and appreciation are described.
