The history of renal transplantation in the Arab world: a view from Saudi Arabia

Challenges to establishing and maintaining kidney transplantation programs in developing countries: What are the coping strategies?

Kidney transplantation (KT) is the optimal form of renal replacement therapy for patients with end-stage renal diseases. However, this health service is not available to all patients, especially in developing countries. The deceased donor KT programs are mostly absent, and the living donor KT centers are scarce. Single-center studies presenting experiences from developing countries usually report a variety of challenges. This review addresses these challenges and the opposing strategies by reviewing the single-center experiences of developing countries. The financial challenges hamper the infrastructural and material availability, coverage of transplant costs, and qualification of medical personnel. The sociocultural challenges influence organ donation, equity of beneficence, and regular follow-up work. Low interests and motives for transplantation may result from high medicolegal responsibilities in KT practice, intense potential psychosocial burdens, complex qualification protocols, and low productivity or compensation for KT practice. Low medical literacy about KT advantages is prevalent among clinicians, patients, and the public. The inefficient organizational and regulatory oversight is translated into inefficient healthcare systems, absent national KT programs and registries, uncoordinated job descriptions and qualification protocols, uncoordinated on-site investigations with regulatory constraints, and the prevalence of commercial KT practices. These challenges resulted in noticeable differences between KT services in developed and developing countries. The coping strategies can be summarized in two main mechanisms: The first mechanism is maximizing the available resources by increasing the rates of living kidney donation, promoting the expertise of medical personnel, reducing material consumption, and supporting the establishment and maintenance of KT programs. The latter warrants the expansion of the public sector and the elimination of non-ethical KT practices. The second mechanism is recruiting external resources, including financial, experience, and training agreements.

Organ transplantation in Arabian Gulf countries: ethical and legal practice and beyond

Almost half a century ago, organ transplantation was introduced to Arabian Gulf countries. The criteria for diagnosing brain death among these countries is relatively similar, in which the main area of discrepancy is the number of physicians required to diagnose and their required specialties. Regarding the organs and tissues allowed for transplantation, they must possess an intrinsic regenerative ability if they are harvested from a living donor to avoid jeopardizing their health. To donate, Arabian Gulf countries follow an opt-in consent system, requiring the donor's informed consent before organ procurement. Live donors can be related or unrelated to the recipient, although the latter is subjected to variable restrictions among Arabian Gulf countries and prohibition in one of them. This is due to its implication in commercial trade. Furthermore, the Gulf Health Council was established to coordinate different health initiatives and programs between Gulf states, including organ transplantation, in an attempt to improve the health sector of all of its member states. Although organ trafficking is illegal in all Arabian Gulf countries, their penalty systems vary from barring physicians, subjecting them to fines or even imprisonment. As for the attitudes of people towards organ transplantation, the willingness to donate varies among these countries. The rate of organ transplantation remains low. This article aims to cover the history of organ transplantation, brain death diagnosis protocols, organ donation enrollment policies and conditions, as well as the issue of organ trafficking in Arabian Gulf countries.

Contribution of Arab world in transplant research: A PubMed-based bibliometric analysis

BACKGROUND

The Arab world consists of 22 countries situated in the Middle East and North Africa, tied together by linguistic and cultural bonds. Over numerous past decades, this region tended to fall behind regarding biomedical research. Organ, tissue, and cell transplantation are life-saving and life-improving treatments for various diseases. Given the positive correlation between research activity and the improvement of the clinical frame of transplantation, this article intended to examine the regional activity of transplantation research between 2005 and 2019.

METHODS

Using the PubMed database, the number of transplantation-related articles published by each country, and regarding 26 different procedures, was assessed. The results were normalized with respect to each country's average population & average Gross Domestic Product (GDP). In addition, the co-occurrence of keywords and the co-authorships were analyzed by VOS Viewer.

RESULTS

Arab countries contributed to 1.25% of total transplantation publications. The number of transplantation publications had an inflection in 2013, with the last six years alone contributing to 65.27% of the overall regional transplantation-related publications. Kuwait and Lebanon ranked first in terms of publications per million persons, while Egypt ranked first in terms of publications per national GDP. Stem cell, bone & kidney transplantations had the highest number of Arab transplantation-related publications. Low levels of collaboration between authors and organizations were observed, besides a modest but increasing trend towards experimental work on animals and newer therapies.

CONCLUSION

Despite the increase in transplant-related research activity in recent years, the Arab world still lags behind in this field compared to the worldwide contribution.

Knowledge, Attitude, and Willingness Toward Kidney Donation Among Health Sciences Students at King Saud Bin Abdulaziz University

Background: End-stage renal disease, as one of the most serious and major health problems, does not have many treatment options available. One of the best treatment modalities used to cure this debilitating disease is kidney transplantation. However, with the continuous increase in number of patients diagnosed with it, there is not enough supply of the organ. The aim of our study is to assess knowledge about, attitude toward, and willingness to donate kidney among health science students at King Saud bin Abdulaziz University in comparison to the general population in Jeddah and to investigate the factors that play a role on their willingness. Methods: This is an observational, analytical, cross-sectional study design conducted in 2019. Two target populations were included: King Saud bin Abdulaziz University for Health Sciences students and the general population in Jeddah. Data were collected via a self-administered, close-ended, structured, and previously validated questionnaire that contained 39 items divided into four sections. SPSS program version 22 was used in data analysis. Results: Out of 685 surveyed participants, 179 (26.1%) were willing to donate their kidney, with students showing a higher rate of willingness (N = 101; 32.3%) than the general population (N = 78; 21%). However, only 46 (6.7%) out of the total population hold an organ donor card. In bivariate analysis, it was found that knowledge significantly associated with a higher rate of willingness among the student population than the general population, while positive beliefs were associated with increased willingness in the general population than students. Positive attitude appeared to play a role in higher willingness among the general population and student population. Conclusion: There is a low perception of awareness regarding kidney donation in both populations of this study. The willingness rate of health science students at King Saud bin Abdulaziz University and the general population was low when compared with other studies conducted internationally.

Donor-derived strongyloidiasis in a Saudi pediatric kidney transplant recipient: A case report and mini-review

S. stercoralis infection has been identified as a donor-derived infection in cases of solid organ transplant among recipients with no prior risk factor for parasitic exposure. Worldwide and regional reports from the adult kidney transplant population highlight this indirect method of infection and caution about delayed diagnosis, severe complications, and death related to donor-derived S. stercoralis infection. We report a deceased-donor-derived S. stercoralis infection in a 12-year-old Saudi girl who underwent kidney transplantation. This is the first pediatric case reported outside the United States of America. Although she presented with mild bouts of gastrointestinal symptoms, the need for additional immune suppression put her at risk of serious complications. A literature review highlights the importance of awareness about S. stercoralis infections and complications in kidney transplant recipients, pretransplant screening of donors based on risk assessment, and the challenges with treatment availability and duration in this vulnerable population.

Thirty Years of Experience at the First Tunisian Kidney Transplant Center

OBJECTIVES

The aim of this study was to report the results of 30 years of experience at the first kidney transplant center in Tunisia.

MATERIALS AND METHODS

All kidney transplants performed at the center between June 1986 and June 2016 were included. The study period was divided into 3 decades. Recipient and donor data and follow-up information were obtained from a local database and patient medical records. Comparative analyses were performed using the t test for continuous variables and the Χ² test for qualitative variables. Patient and graft survival rates were calculated according to the actuarial method, and comparison of survival curves was performed according to the logrank test.

RESULTS

The mean age of recipients was 32.7 ± 11.5 years (range, 6-65 y) with a gender ratio of 2.2. Duration of prekidney transplant dialysis varied from 2 months to 20 years (median, 27.5 mo); 1.7% of patients underwent transplant preemptively. Kidneys were recovered from deceased donors in 21.2% of cases and from living donors in 78.8%. The proportion of deceased donors dropped from 27.4% during the period 2006-2010 to 12.9% during the period 2011-2015 (P < .04). Patient survival rates at 1, 5, 10, 15, and 20 years were 96%, 89.3%, 79.5%, 71.1%, and 65.4%. Graft survival rates were 95%, 86.5%, 76.2%, 66.3%, and 57.2%. The annual graft loss was 2.9%, with a mortality rate of 2.4% and without significant differences between patients receiving deceased-donor and living-donor organs.

CONCLUSIONS

Kidney transplant activity remains suboptimal in our country. The reduction in deceased-donor organs could be related to the political transformations facing our country with their resulting social and economic consequences. Efforts should be made to increase governmental resources and to improve both public awareness of organ donation and the motivation of transplant teams.

Opinions on the Legitimacy of Brain Death Among Sunni and Shi'a Scholars

The concept of brain death poses a great challenge to clinicians who may be required to bridge the interface of culture, religion, law, and medicine. This review discusses and applies Islamic jurisprudence to the question of whether brain death is accepted as true death under Islamic law. Among the five sources of Islamic law, the Qur'an and Sunnah do not directly address brain death. Scholarly consensus (Ijmā') does not exist, and Qiya does not apply. When applying Ijtihad, the identified collection of non-binding fatwā offer conflicting results. Debate continues as to the validity of brain-death criteria within Islamic circles.

Brain death and Islam: the interface of religion, culture, history, law, and modern medicine

How one defines death may vary. It is important for clinicians to recognize those aspects of a patient's religious beliefs that may directly influence medical care and how such practices may interface with local laws governing the determination of death. Debate continues about the validity and certainty of brain death criteria within Islamic traditions. A search of PubMed, Scopus, EMBASE, Web of Science, PsycNet, Sociological Abstracts, DIALOGUE ProQuest, Lexus Nexus, Google, and applicable religious texts was conducted to address the question of whether brain death is accepted as true death among Islamic scholars and clinicians and to discuss how divergent opinions may affect clinical care. The results of the literature review inform this discussion. Brain death has been acknowledged as representing true death by many Muslim scholars and medical organizations, including the Islamic Fiqh Academies of the Organization of the Islamic Conference and the Muslim World League, the Islamic Medical Association of North America, and other faith-based medical organizations as well as legal rulings by multiple Islamic nations. However, consensus in the Muslim world is not unanimous, and a sizable minority accepts death by cardiopulmonary criteria only.

Limitations of cadaveric organ donation on judicial cases and problems confronted in autopsy: Istanbul data in comparative perspective

Organ transplantation is one of the most important services of modern medicine to the humanity. In judicial death cases the interaction between judicial needs and transplantation needs is inevitable and both should be provided in a short time before the decomposition of the body. Thus, the description of this interaction and the algorithm which should be carried out to manage these cases are important. Aim of this study is to determine the problems confronted in forensic autopsies and to determine what to do for both judicial processes' and cadaveric organ donations' not becoming limited due to each other. With these aims, autopsy case archive of the Council of Forensic Medicine Istanbul Morgue Department was reviewed, between the years 2009 and 2011, to reveal the number of organ donors among autopsy cases and also to find out the judicial problems confronted during autopsies. Among 12,016 judicial death cases referred to Istanbul Morgue Department in 3 years, 35 cases were found to have undergone cadaveric solid organ harvesting procedure and 307 cases cornea-only harvesting procedure. Manner of deaths for organ donor cases were blunt trauma due to traffic accident in 20 cases, firearm injury in 3 cases, stabbing in 2 cases, suspicious criminal battery in 4 cases and fatal falls in 5 cases. Only 1 case was suspected to have died due to high dose insulin administration. Through the whole data presented in this study, it can be concluded that consulting with the Forensic Medicine Expert not only for the autopsies but also during the clinical process of a judicial case, who is a candidate to be an organ donor, is absolutely important. The early contribution of the Forensic Medicine Expert would provide help to plan both the judicial process and the transplantation process which needs urgent decisions. A Forensic Medicine Expert may be an organ harvest team member performing initial investigations on the cause of death and collecting some of the toxicological screening samples when needed.

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.

Religious attitudes towards living kidney donation among Dutch renal patients

Terminal kidney patients are faced with lower quality of life, restricted diets and higher morbidity and mortality rates while waiting for deceased donor kidney transplantation. Fortunately, living kidney donation has proven to be a better treatment alternative (e.g. in terms of waiting time and graft survival rates). We observed an inequality in the number of living kidney transplantations performed between the non-European and the European patients in our center. Such inequality has been also observed elsewhere in this field and it has been suggested that this inequality relates to, among other things, attitude differences towards donation based on religious beliefs. In this qualitative research we investigated whether religion might indeed (partly) be the explanation of the inequalities in living donor kidney transplants (LDKT) among non-European patients. Fifty patients participated in focus group discussions and in-depth interviews. The interviews were conducted following the focus group method and analyzed in line with Grounded Theory. The qualitative data analyses were performed in Atlas.ti. We found that religion is not perceived as an obstacle to living donation and that religion actually promotes helping and saving the life of a person. Issues such as integrity of the body were not seen as barriers to LDKT. We observed also that there are still uncertainties and a lack of awareness about the position of religion regarding living organ donation within communities, confusion due to varying interpretations of Holy Scriptures and misconceptions regarding the process of donation. Faith leaders play an important educational role and their opinion is influential. This study has identified modifiable factors which may contribute to the ethnic disparity in our living donation program. We argue that we need to strive for more clarity and awareness regarding the stance of religion on the issue of living donation in the local community. Faith leaders could be key figures in increasing awareness and alleviating uncertainty regarding living donation and transplantation.

Pregnancy in renal transplantation: Recipient and donor aspects in the Arab world

OBJECTIVE

There are many kidney transplant recipients and living donors of reproductive age, and the prevalence of pregnancies in kidney transplant recipients can reach 55% in the Middle Eastern countries. Living kidney donation is predominant in this region. As the risks and outcomes of pregnancy should be a part of counselling for both recipients and donors, we reviewed available reports on maternal and foetal outcomes in these particular populations.

METHODS

Information was obtained from retrospective analyses of a large database, and from single-centre reports indexed in PubMed on pregnancy in donors and kidney transplant recipients. The keywords used for the search included 'fertility', 'kidney disease', 'pregnancy', 'maternal/foetal outcomes', 'kidney transplant recipient', 'immunosuppression side-effects', 'living donor' and 'Arab countries'.

RESULTS

Pregnancies in kidney transplant recipients are most successful in those with adequate kidney function and controlled comorbidities. Similarly to other regions, pregnant recipients in the Middle East had a higher risk of pre-eclampsia (26%) and gestational diabetes (7%) than in the general population. Caesarean section was quite common, with an incidence rate of 61%, and the incidence of pre-term birth reached 46%.

CONCLUSIONS

Most living donors can have successful pregnancies and should not be routinely discouraged. Women who had pregnancies before and after donation were more likely to have adverse maternal outcomes (gestational diabetes, hypertension, proteinuria, and pre-eclampsia) in the latter, but no adverse foetal outcomes were found after donation. The evaluation before donation should include a gestational history and counselling about the potential risks.

Time to move away from damage control strategy in hemodialysis vascular access management: a view from Saudi Arabia

For the last 40 years, most of the research and publications on hemodialysis access, has focused on the management of its complications e.g. thrombosis, infection, aneurysms. In other words, a damage control strategy. While this is undoubtedly an important part of access management, it is a deficient reactive strategy that does not enhance a better quality of life for patients or help reduce the burden on health care resources. To achieve these objectives, efforts should be directed at ways which provide a longer access life with fewer complications. Such an approach would save costs and reduce the suffering of the patient. In this paper we will focus on hemodialysis management in Saudi Arabia, describe the reasons for the current unsatisfactory situation, and highlight possible remedies.

Altruistic, cognitive and attitudinal determinants of organ donation intention in Egypt: a social marketing perspective

This study investigates the influence of various altruistic, cognitive, and attitudinal factors on the organ donation intention in Egypt. Using a large sample, a conceptual model has been developed. The findings from the structural equation model confirm the influence of the respondents' altruistic values, perceived benefits and risks, and knowledge on their attitudes towards organ donation. Respondents' attitudes towards organ donation, in turn, are also found to affect their organ donation intention. One of the other important findings suggests that on a declarative level, more and more individuals in Egypt express their concern over the shortage of available organs and declare their willingness to contribute somehow to alleviate the problem. However, in reality this concern may not be manifested consistently.

Reasons for unwillingness of libyans to donate organs after death

Introduction

Organ transplantation in Libya depends exclusively on donations from live relatives. This limitation increases mortality and prolongs the patients’ suffering and waiting time.

Objectives

The aims of this study were to explore willingness to donate organs after death and to identify the reasons for refusal.

Methods

A population-based crosssectional study was conducted from April to July 2008 on a cluster sample of 1652 persons (58% males and 42% females). The questionnaire included demographic information and mainly enquired about willingness to donate organs after death and the reasons for refusal when applicable.

Results

About one-third (29.7%) of participants were in favor of donating their organs after death, 60.1% refused and 10.2% were undecided. Willingness was significantly associated with being male, younger age, having a college or graduate degree, and being single (P <0.05 for all). Lack of adequate knowledge about the importance of deceased organ donation and uncertainty about its religious implications were the most predominant reasons for refusal (43.8% and 39.5%, respectively). Other reasons included ethical concerns about retrieving organs from dead bodies (37.9%), preference for being buried intact (28%), and uneasiness about the idea of cadaver manipulation (33%).

Conclusion

There were a considerable resistance to deceased organ donation, especially among females, those of older age, married people, and those with a low education level. The barriers to cadaveric donations were lack of adequate knowledge, unease about body manipulation, and concerns about religious implications. Public educational campaigns should be coordinated with religious leadership.
