The tissue biobanking of specific biological residual materials, which constitutes a useful resource for medical/scientific research, has raised some ethical issues, such as the need to define which kind of consent is applicable for biological residual materials biobanks.

Background: Seeking consent for genetic and genomic research can be challenging, particularly in populations with low literacy levels, and in emergency situations. All of these factors were relevant to the MalariaGEN study of genetic factors influencing immune responses to malaria in northern rural Ghana. This study sought to identify issues arising in practice during the enrolment of paediatric cases with severe malaria and matched healthy controls into the MalariaGEN study. Methods: The study used a rapid assessment incorporating multiple qualitative methods (...) including in depth interviews, focus group discussions and observations of consent processes. Differences between verbal information provided during community engagement processes, and consent processes during the enrolment of cases and controls were identified, as well as the factors influencing the tailoring of such information. Results: MalariaGEN participants and field staff seeking consent were generally satisfied with their understanding of the project and were familiar with aspects of the study relating to malaria. Some genetic aspects of the study were also well understood. Participants and staff seeking consent were less aware of the methodologies employed during genomic research and their implications, such as the breadth of data generated and the potential for future secondary research.Moreover, trust in and previous experience with the Navrongo Health Research Centre which was conducting the research influenced beliefs about the benefits of participating in the MalariaGEN study and subsequent decision-making about research participation. Conclusions: It is important to recognise that some aspects of complex genomic research may be of less interest to and less well understood by research participants and that such gaps in understanding may not be entirely addressed by best practice in the design and conduct of consent processes. In such circumstances consideration needs to be given to additional protections for participants that may need to be implemented in such research, and how best to provide such protections.Capacity building for research ethics committees with limited familiarity with genetic and genomic research, and appropriate engagement with communities to elicit opinions of the ethical issues arising and acceptability of downstream uses of genome wide association data are likely to be important.

Background Genetic databases are becoming increasingly common as a means of determining the relationship between lifestyle, environmental exposures and genetic diseases. These databases rely on large numbers of research subjects contributing their genetic material to successfully explore the genetic basis of disease. However, as all possible research questions that can be posed of the data are unknown, an unresolved ethical issue is the status of informed consent for future research uses of genetic material. Discussion In this paper, we discuss the (...) difficulties of an informed consent model for future ineffable uses of genetic data. We argue that variations on consent, such as presumed consent, blanket consent or constructed consent fail to meet the standards required by current informed consent doctrine and are distortions of the original concept. In this paper, we propose the concept of an authorization model whereby participants in genetic data banks are able to exercise a certain amount of control over future uses of genetic data. We argue this preserves the autonomy of individuals at the same time as allowing them to give permission and discretion to researchers for certain types of research. Summary The authorization model represents a step forward in the debate about informed consent in genetic databases. The move towards an authorization model would require changes in the regulatory and legislative environments. Additionally, empirical support of the utility and acceptability of authorization is required. (shrink)

Background: Sharing of tissue samples for research and disease surveillance purposes has become increasingly important. While it is clear that this is an area of intense, international controversy, there is an absence of data about what researchers themselves and those involved in the transfer of samples think about these issues, particularly in developing countries. Methods: A survey was carried out in a number of Asian countries and in Egypt to explore what researchers and others involved in research, storage and transfer (...) of human tissue samples thought about some of the issues related to sharing of such samples. Results: The results demonstrated broad agreement with the positions taken by developing countries in the current debate, favoring quite severe restrictions on the use of samples by developed countries. Conclusions: It is recommended that an international agreement is developed on what conditions should be attached to any sharing of human tissue samples across borders. (shrink)

The ethics of biobanking is one of the most controversial issues in current bioethics and public health debates. For some, biobanks offer the possibility of unprecedented advances which will revolutionise research and improve the health of future generations. For others they are worrying repositories of personal information and tissue which will be used without sufficient respect for those from whom they came. Wherever one stands on this spectrum, from an ethics perspective biobanks are revolutionary. Traditional ethical safeguards of informed consent (...) and confidentiality, for example, simply don’t work for the governance of biobanks and as a result new ethical structures are required. Thus it is not too great a claim to say that biobanks require a rethinking of our ethical assumptions and frameworks which we have applied generally to other issues in ethics. This paper maps the key challenges and controversies of biobanking ethics; it considers; informed consent (its problems in biobanking and possibilities of participants’ withdrawal), broad consent, the problems of confidentiality, ownership, property and comercialisation issues, feedback to participants and the ethics of re-contact.

Background: The banking of biological samples raises a number of ethical issues in relation to the storage,export and re-use of samples. Whilst there is a growing body of literature exploringparticipant perspectives in North America and Europe, hardly any studies have been reportedin Africa. This is problematic in particular in light of the growing amount of research takingplace in Africa, and with the rise of biobanking practices also on the African continent. Inorder to investigate the perspectives of African research participants, we (...) conducted a studywith research participants in a TB study in the Western Cape, South Africa. Methods: Semi-structured interviews were conducted using an interview guide which drew on the mostprominent themes expressed in current literature on sample storage, re-use and exportation.Interviews were conducted in Afrikaans and subsequently translated into English by the sameinterviewer. Interviews were transcribed verbatim and analysed qualitatively. Results: The results of our study indicate that the majority of participants were supportive of givingone-time consent to the storage and re-use of their samples. The concept of research being fora "good cause" was a central prerequisite. Additionally, a significant minority requested thatthey be re-contacted if a future use was not stipulated on the original consent. There was alsoconsiderable variation in how participants understood the concept of a 'good cause', withparticipants describing three distinct categories of research, of which two were generallythought to constitute 'good cause' research. Research that was for-profit was considered tofall outside the spectrum of 'good cause' research. Participants displayed confidence in theabilities of the researchers to make future decisions regarding sample use, but seemedunaware of the role of ethics committees in either this process or more generally. Conclusions: Participants expressed a wide and complex range of views about issues of sample storage andre-use, and they showed a great deal of trust in researchers. Participants' willingness to havetheir samples stored and re-used is consistent with findings from existing studies. However,in contrast to existing literature, participants were generally not in favour of for-profitresearch. Further research needs to be done to explore these ideas in other communities, bothin South Africa and other countries. (shrink)

Health research is increasingly being conducted on a global scale, particularly in the developing world to address leading causes of morbidity and mortality. While research interest has increased, building scientific capacity in the developing world has not kept pace. This often leads to the export of human tissue (defined broadly) from the developing to the developed world for analysis. These practices raise a number of important ethical issues that require attention.

The use of biological samples in research raises a number of ethical issues in relation to consent, storage, export, benefit sharing and re-use of samples. Participant perspectives have been explored in North America and Europe, with only a few studies reported in Africa. The amount of research being conducted in Africa is growing exponentially with volumes of biological samples being exported from the African continent. In order to investigate the perspectives of African research participants, we conducted a study at research (...) sites in the Western Cape and Gauteng, South Africa. (shrink)

While the socio-ethical and legal issues surrounding clinical genetics have long been the subject of international interest, the thorny questions of genetic research and biobanking are more recent. Add to this the fact that national guidelines and laws usually precede international policymaking, and the delay in international approaches is understandable. In that regard, the United Nations Educational, Scientific and Cultural Organization’s 1997 Universal Declaration on the Human Genome and Human Rights is unique in its prospective guidance on genetic research. Also, (...) it is in the very nature of international normative instruments to be general, except on specific issues considered to be in the interest of humanity, such as research into human reproductive cloning or access to AIDS drugs.

ABSTRACT There is growing concern about the reuse and exportation of biological materials (human tissues) for use in research worldwide. Most discussions about samples have taken place in developed countries, where genetic manipulation techniques have greatly advanced in recent years. There is very little discussion in developing countries, although collaborative research with institutions from developed countries is on the increase. The study sought to identify and describe ethical issues arising in the storage, reuse and exportation of samples in a developing (...) country. Research protocols presented to two Ethics Review Committees in Kenya during a period of two years were reviewed. A record was made of the protocol title, sample collected, request for storage, reuse or exportation and whether or not subject consent was sought. The findings indicated that about 25% out of the 388 protocols sought permission for reuse and only half of those actually informed subjects of the contemplated re‐use. Less than 20% requested storage and again, about half of them sought consent from subjects. There is an indication that investigators do not see the need to seek consent for storage, reuse and exportation of samples. It is proposed that these issues should be addressed through policy interventions at both the national and global levels. (shrink)

Background Interest in biobanking for collection of specimens for non-communicable diseases research has grown in recent times. This paper explores the perspectives of Nigerians on donation of specimen for the biobanking research. Methods We conducted 16 Focus Group Discussions (FGD) with individuals from different ethnic, age and socio-economic groups in Kano (North), Enugu (Southeast), Oyo States (Southwest) and Abuja, the Federal Capital Territory (Central) of Nigeria. We used topic guides and prompt statements to explore the knowledge and understanding of interviewees (...) to general issues about biobanking of biospecimens, their use and specifically about role of biobanking in non-communicable diseases research. Results A total of 123 individuals participated in 16 focus group discussions in 2011. Our participants had limited knowledge of the concept of biobanking but accepted it once they were educated about it and saw it as a worthwhile venture. Half of our study participants supported use of broad consent, a quarter supported restricted consent while the remaining quarter were in favour of tiered consent. Most discussants support shipment of their samples to other countries for further research, but they prefer those collaborations to be done only with competent, ethical researchers and they would like to receive feedback about such projects. The majority preferred health care as a benefit from participation, particularly for any unexpected condition that may be discovered during the course of the research instead of financial compensation. Participants emphasized the need to ensure that donated samples were not used for research that contradicts their religious beliefs. Conclusions Our study demonstrates that our participants accepted biobanking once they understand it but there were different attitudes to elements of biobanking such as type of consent. Our study highlights the need to carefully document population attitudes to elements of modern scientific research and the consenting process. (shrink)

Biomedical research has always relied on access to human biological materials and clinical information, resources that when combined form biobanks. In the past, it appears that investigators sometimes used these resources with relatively little oversight, and without the consent of the individuals from whom these materials and information were obtained. Several developments in the last ten to fifteen years have converged to place greater emphasis on the role of individual consent in the creation and use of biobanks. The most important (...) by far is the power of information technology, which has transformed our lives in almost every domain. In the research setting, it is now easy to abstract information from electronic medical records. Computers make it possible to analyze enormous datasets and have contributed in essential ways to the dramatic increases in our understanding of genomics and other areas of biomedical science.

ABSTRACT A major moral problem in relation to the deCODE genetics database project in Iceland is that the heavy emphasis placed on technical security of healthcare information has precluded discussion about the issue of consent for participation in the database. On the other hand, critics who have emphasised the issue of consent have most often demanded that informed consent for participation in research be obtained. While I think that individual consent is of major significance, I argue that this demand for (...) informed consent is neither suitable nor desirable in this case. I distinguish between three aspects of the database and show that different types of consent are appropriate for each. In particular, I describe the idea of a written authorisation based on general information about the database as an alternative to informed consent and presumed consent in database research. (shrink)
